Description

Pick-up device for an insert element

The invention relates to a receiving device for an insert element, in particular for a needle arrangement for taking off body fluids, tissue parts or tissue cultures, as described in claim 1.

A known receiving device for an insert element has become known from US Pat. No. 5,755,673 A or WO 97/24067 A1, in which the receiving device comprises a receiving container with end regions spaced apart from one another, between which a container jacket extends, the first end region being open and the further end area is closed by an end wall. The container casing and the end wall delimit an interior space, a holding device for an insert element which can be inserted into the receiving device being arranged on the end wall in the region of the closed end region. In the end wall of the receptacle, an opening passing through it is arranged approximately in a center thereof, the holding device being formed by holding elements which can be pivoted in opposite directions and which are adjustable by means of an actuating device, starting from a blocking position into a release position. The actuating device is formed by a slide, which is adjustably mounted in a guide device in a direction parallel to the end wall. The holding device and the actuating device are covered with their own cover part on the side facing away from the interior and thus prevented from unintentional loosening. The holding device is adjusted by actuating the actuating device in the form of an associated swiveling operation of the two holding elements.

Another receiving device for an insert element, in particular a needle arrangement, has become known from US Pat. No. 5,797,490 A, which likewise comprises a receiving container which has end regions which are spaced apart from one another and between which the container jacket extends. The first end area is again open and the further end area is closed by an end wall. In the region of the end wall, the holding device for the insert element and an actuating device for the holding device are provided, which is mounted in a guide device in a direction parallel to the end wall and adjustable relative to the receiving container. The holding device comprises two holding elements which have half-shells with a corresponding nut thread. These two holding elements are opposite the receptacle by means of a locking element positioned held, a first holding element is held almost immovably by means of the positioning element in a predeterminable position with respect to the receiving container. The second holding element is, if necessary, held adjustably in a plane parallel to the end wall by means of the positioning element, the two mutually facing half-shells forming a closed receiving bore with an internal thread for the needle arrangement in the blocking position for the needle arrangement. By means of a further actuating element, the further or second holding element can be adjusted from the locked position to the release position by displacement in a direction parallel to the end wall.

The present invention has for its object to provide a receiving device of the type described above, the simple and one-handed operation of the actuating device and associated on the one hand a secure and firm mounting of the needle assembly in the locked position and on the other hand a secure release of the same in the release position enables.

This object of the invention is achieved by the features of claim 1. The surprising advantage resulting from the features of the characterizing part of claim 1 is that the combined arrangement of the opening penetrating the wall of the receiving body or the end wall of the receiving container in the region of the longitudinal central axis with the two diametrically opposite supporting elements and the design of the slide with the opening and the holding element forming the holding device and the release element in the opening, a very simple holding device consisting only of the integrally formed slide and the receiving body or receiving container is created. Due to this solution, which appears to be very simple, the insert element or the needle arrangement is held in the locked position of the slide with respect to the receiving body or receiving container in a fixed position in which the insert device with the insert element or the needle arrangement held therein can be used properly can be done. After the intended use, it is now possible for a user of such a receiving device to easily move the slide with the insert element or the needle arrangement from its locked position into the release position, in which the insert element or the needle arrangement is caused by the transverse movement - Movement of the slide in relation to the receptacle from the release element in a position detachable from the receptacle or slider and the used needle arrangement in a position in which the from the receptacle pointing away needle point in the direction of the ground or the earth shows, due to gravity or gravity can be easily removed with one hand, without further contact takes place. Furthermore, a very simple and, above all, cost-effective design of the receiving device, consisting of the receiving body or receiving container and the one-piece slide, for receiving the needle arrangement in relation to the manufacturing costs and assembly costs, which is due to the simple structure, is also advantageously created , which distinguishes operational safety and one-hand operation.

Another embodiment according to claim 2 is also advantageous. This configuration of the receiving body by means of a receiving container makes it easy to use for a removal process without the user being injured by the further needle tip in the region of the interior. In addition, easier handling is ensured due to the design of the receptacle.

Furthermore, an embodiment according to claim 3 is advantageous, since the one-piece design of the slide means that on the one hand a high manufacturing effort, which would be incurred in a plurality of parts, is eliminated and, likewise, assembly on the receptacle is also simplified and less expensive due to the one-piece design .

The configuration according to claim 4 makes it possible to ensure an exact transverse adjustment of the slide in a direction parallel to the end wall, in order to ensure simple one-hand operation.

According to another embodiment variant according to claim 5 or 6, a more precise guidance of the slide in relation to the receptacle is made possible, wherein in addition a limitation of the adjustment path can be achieved.

In the embodiments according to claims 7 to 10, the insert element or the needle arrangement can be supported exactly on one of the support surfaces of the support elements without the needle arrangement being displaced relative to the receiving body or receiving container.

Formations according to claims 11 to 16 are also advantageous since, due to these, different arrangements of the holding element and the release element on the one hand the holding force of the insert element or the needle arrangement on the receiving device and on the other hand the adjusting force to be applied can be determined. The greater the distance selected in the direction of the opening between the holding element and the release element, the greater the length of circle segments which serve to hold the insert element or the needle arrangement. At the same time, however, the passage cross section between the holding element and the release element is reduced, which leads to an increase in the adjusting force.

An embodiment according to claim 17 is also possible, since an exact positioning of the holding element or the release element in relation to the opening penetrating the wall or end wall can thereby be achieved.

The embodiments according to claims 18 to 20 allow an additional ejection or during the adjustment process of the slide with respect to the receiving container. Release force starting from the support surfaces inclined to the cover surface, whereby the release movement of the insert element or the needle arrangement is supported by the receiving device in the manner of a "kick-off" effect. Due to this rapid loosening process in the manner of an ejection movement, with the needle pointing downward, even when the needle is inclined, the loosening process takes place so quickly that even with an inclined position of the needle arrangement with respect to the receptacle, that part of the needle located in the interior of the receptacle is rubbed against one of the components of the receiving device is securely avoided. This also reliably prevents contamination of the entire receiving device.

Further advantageous embodiments of the receiving device are characterized in claims 21 to 49, the advantages achievable in this context being apparent from the detailed description.

Finally, other advantageous developments are described in claims 50 to 54, whereby a widening of the individual webs in the locked position is prevented and a stable and, above all, secure mounting of the needle arrangement in the use position can be achieved. At the same time, this also results in a reinforcing or stiffening effect of the webs, which, however, is canceled immediately when the locking position is released and the needle arrangement is released easily and securely in the release position. The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally etc. refer to the figure described and illustrated immediately and are to be transferred to the new position in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 to 8 show a receiving device 1 for an insert element, in particular for a needle arrangement 2 for taking off body fluids, tissue parts or tissue cultures, which have a receiving body, e.g. a receiving container 3, and a holding device 4, an actuating device 5 and optionally a guide device 6 comprises. The shape of the receptacle body or receptacle 3 can vary widely. However, it is also possible for the receiving device 1 to be used to hold the insert element releasably, if necessary, and also to be used for the administration of medication, solutions, mixtures, etc., instead of taking off body fluids or the like.

The receptacle 3 of the receptacle 1 has end regions 7, 8 spaced apart from one another, between which a container casing 9 extends. The first end region 7 of the receptacle 3 is open and the further end region 8 is closed by an end wall 10. As a result of the arrangement and design of the container shell 9 in connection with the end wall 10, these enclose an interior space 11, a longitudinal central axis 12 extending between the two end regions 7 and 8 approximately in a center of the container shell 9. An inner surface 13 of the container shell 9 and an inner surface 14 of the end wall 10 face the interior 11 of the receptacle 3. Furthermore, the receptacle 3 has an outer surface 15 on the side facing away from the interior 11 in the area of the container casing 9 and a further outer surface 16 in the area of the end wall 10. As can now be seen better from FIGS. 2 and 3, the end wall 10 of the receptacle 3 has an opening 17 passing through the end wall 10 approximately in the region of the longitudinal central axis 12. This opening 17 serves to receive the needle arrangement 2, which is held on the receiving device 1 by means of the holding device 4 and a part of a cannula 18, which is not shown here, protrudes into the interior 11 of the receiving container 3. The cross-sectional shape of the opening 17 can be selected in a wide variety of ways, depending on the application. This needle arrangement 2 is designed in this embodiment such that the cannula 18 is formed by a one-piece hollow needle with tips provided on both ends. Since the needle arrangement 2 can be designed in a wide variety of ways and is part of the generally known prior art, a detailed description thereof is omitted. Furthermore, the needle arrangement 2 has, over the longitudinal course in the direction of the longitudinal central axis 12, approximately in a central region of the same, a positioning element 19 which is designed such that it can be detachably held on the receiving device 1 by means of the holding device 4. The detailed description of the holding device 4 and its mode of operation is given below.

Of course, however, it is also possible for the receiving body of the receiving device 1 to have at least one wall in which the opening 17 is arranged and provided with the guide device 6. In addition, however, any differently designed insert element can be held instead of the needle arrangement 2.

In addition, at the end of the cannula 18 which faces the interior 11 of the receptacle 3, a cover device in the form of a hose valve, which can be pierced or opened as required, can also be arranged.

For easier handling or operation of the receiving device 1, a handle is formed on the container jacket 9 in the region of the open end region 7, which handle has only been shown here in a simplified, schematic manner. Both the handle and the end wall 10 are preferably aligned in a plane 20 extending approximately perpendicular to the longitudinal central axis 12.

The receiving device 1 shown and described here with the needle arrangement 2 inserted into it serves to receive a blood sampling tube (not shown in more detail) in the region of the interior 11 enclosed by the container jacket 9. The blood sampling tube can, for example, according to the information WO 89/09735 be formed and consists of a cylindrical housing open on one side, which is closed on the open end by means of a gas-tight closure device. The closure device in turn consists of a cap which overlaps the housing and a stopper which closes an interior of the housing. The interior of the

Blood sampling tubes can be used when unused, e.g. be evacuated to a vacuum between 100 mbar and 800 mbar.

The outer surface 16 in the region of the end wall 10 forms a plane 20 oriented approximately perpendicular to the longitudinal central axis 12, parts of the guide device 6 in the form of guide elements 21 being arranged in the region of the surface 16. A schematically indicated parting plane 22 runs through the center of the longitudinal center axis 12 and can also be referred to as the plane of symmetry in this exemplary embodiment. Due to the parallel alignment to the longitudinal central axis 12, this parting plane 22 is at a right angle, that is to say perpendicular, to the plane

20 arranged. The two guide elements 21 of the guide device 6 described above are arranged on both sides of the parting plane 22 on the outer surface 16 of the end wall 10 and protrude beyond the side facing away from the interior 11. Due to this symmetrical arrangement of the two guide elements 21 with respect to the parting plane 22, one speaks of the arrangement of two guide elements

21 also from a diametrically opposite arrangement.

As can now be seen better from FIG. 3, the guide elements 21 each have an approximately L-shaped cross section, which is designed in the form of a profile 23, one leg 24, 25 of the end wall 10 of the receiving container 3 facing and connected to this. The profiles 23 forming the guide elements 21 have on the side facing away from the end wall 10 further legs 26, 27 or projections or projections which face one another or are aligned in the direction of the parting plane 22 and are spaced apart from the outer surface 16 of the end wall 10 are. The interaction of the guide elements 21 with the actuating device 5 will be described in detail in one of the following figures. Furthermore, it is possible for guide surfaces 28 to 33 to be formed in the region of the legs 24 to 27 on the side facing the end wall 10. Depending on the different design of the actuating device 5 with the guiding device 6, different guiding surfaces 28 to 33 can be used for guiding. In this exemplary embodiment shown here, the guide surfaces 28, 30 and 31 and 33 are parallel to the parting plane 22 and the guide surfaces 29, 32 aligned parallel to level 20. Of course, it is also possible to align the individual guide surfaces 28 to 33 at an angle with respect to plane 20 or parting plane 22. It is essential, however, that a distance between guide surfaces 28, 31 or 30, 33 facing each other is chosen to be constant over their longitudinal course.

The guide surfaces 28, 29 and 31, 32, which are angled, in particular perpendicular to one another, form groove-shaped guide channels with the surface 16 of the end wall 10 on both sides of the parting plane 22. The further guide surfaces 30, 33 can also be angular, in particular perpendicular to the

Guide surfaces 29, 32 may be aligned. These guide channels of the guide elements 21, delimited by the legs 24 to 27, are used to guide the actuating device 5 parallel to the plane 20 and in the direction of the parting plane 22 relative to the receiving container 3, as required, on the latter.

As can further be seen from FIGS. 2 and 3, at least one, preferably a plurality of support elements 34, 35 are arranged in the region of the end wall 10 on the side facing away from the interior 11, which in this exemplary embodiment are parallel to the guide surfaces 28, 30 and 31, respectively , 33 are aligned in their longitudinal extent. Furthermore, the support elements 34, 35 are arranged one behind the other in the region of the parting plane 22 and on both sides of the opening 17. These support elements 34, 35 also project beyond the surface 16 of the end wall 10 on the side facing away from the interior 11, ends 36, 37 of the support elements 34, 35 facing away from one another being arranged at a distance 38 from one another. The support elements 34, 35 have a thickness 39 transversely to the longitudinal extent in a direction perpendicular to the parting plane 22, which is preferably smaller than a clear inner dimension 40 of the opening 17 in the end wall 10. As already described above, the two support elements 34, 35 are arranged in the parting plane 22, and in the direction of the parting plane 22 it can also be said that the two supporting elements 34, 35 or a diametrical arrangement are arranged one behind the other. In the embodiment shown here, two support elements 34, 35 are shown and described, but it is of course possible to arrange only a single support element 34 or 35 which is penetrated by the opening 17. Irrespective of this, it is also possible to arrange several of these support elements 34, 35 in the area of the surface 16 of the end wall 10.

Mutually facing ends 41, 42 of the two support elements 34, 35 each form Support surfaces 43, 44, which are preferably arranged directly adjacent to the opening 17 in the end wall 10 of the receptacle 3. These support surfaces 43, 44 can be flat, parallel to one another or curved in relation to the longitudinal central axis 12. The mutually facing support surfaces 43, 44 can, however, also be concave or formed by part of a cylindrical surface, a center of curvature of these partial surfaces being able to run through the longitudinal central axis 12. The design of the opening 17 in its cross-sectional shape can also be freely selected depending on the application and can be, for example, circular, elliptical, square, rectangular, and possibly also polygonal. In this exemplary embodiment shown here, a circular representation has been chosen, but it is of course also possible to make the opening 17 square. It is also shown here that the two support surfaces 43, 44 are arranged approximately flush with the boundary surfaces of the opening 17 and are aligned with them. Of course, it is also possible to arrange these support surfaces 43, 44 at a distance from the boundary surfaces of the opening 17. It is advantageous if the support surfaces 43, 44 are aligned parallel to one another and parallel to the longitudinal central axis 12. The interaction of the support elements 34, 35 and their support surfaces 43, 44 with the actuating device 5 and the needle arrangement 2 will also be described in more detail in the following figures.

4 to 6, the actuating device 5 for the receiving device 1 is shown in detail, which in this embodiment is formed by a slide 45. This slide 45 is approximately plate-shaped and, in its position on the receptacle 3, has a bearing surface 46 facing the end wall 10 of the receptacle 3 and a cover surface 47 distanced therefrom. Side surfaces 48 to 51 extend between the support surface 46 and the top surface 47, as a result of which the slider 45 is approximately fixed in its spatial shape.

5 shows a schematically indicated further parting plane 52, which in this exemplary embodiment also approximately forms a plane of symmetry and is arranged approximately in the direction of the longitudinal extension of the slide 45. In the area of this parting plane 52, a preferably slot-shaped opening 53 is arranged in the slide 45, which extends between the support surface 46 and the top surface 47. This opening 53 has a length 54 in the direction of the parting plane 52 or in the longitudinal extension of the slide 45 and a width 55 in the direction perpendicular thereto. Furthermore, the previously described holding device 4 for the needle arrangement 2 is provided in the region of the longitudinal course of the opening 53, which in this exemplary embodiment is formed by a holding element 56 and a release element 57.

In this exemplary embodiment, the length 54 of the opening 53 is selected to be greater than its width 55. Furthermore, the length 54 of the opening 53 in its longitudinal extent is greater than the greatest distance 38 between the ends 36, 37 of the two supporting elements 34, 35 facing away from one another this difference in length between the length 54 of the opening 53 and the distance 38 enables an adjustment movement of the slide 45 in the plane 20 in the longitudinal direction of the opening 53 in cooperation with the support elements 34, 35. Furthermore, the width 55 of the opening 53 is at least the same, but preferably greater than the thickness 39 of the two support elements 34, 35, which prevents the slider 45 from rotating with respect to the receiving container 3 if the tolerances are selected accordingly.

Furthermore, it is possible to arrange additional guide elements 58 for guiding the relative adjustment movement of the slide 45 in relation to the receptacle 3 in the area of the side surfaces 48, 49, which interact with the guide elements 21 of the receptacle 3 and form the guide device 6. In this exemplary embodiment, the two guide elements 58 on the slide 45 are formed by recesses 59, 60 arranged on both sides of the slide 45 in the transition region between the cover surface 47 and the side surfaces 48 and 49, which are preferably aligned parallel to one another, each of the recesses 59, 60 being formed by Sliding surfaces 61 to 64 is limited, which are preferably aligned parallel to the longitudinal extent of the opening 53 in the slide 45. A length 65 of the individual sliding surfaces 61 to 64 in the slide 45 corresponds to at least one longitudinal dimension 66 of the guide elements 21 on the receiving container 3 plus a center distance 67 between the center of the holding element 56 and the center of the release element 57.

In this exemplary embodiment, the holding element 56 is formed in the slide 45 by a bore 68 which is provided with an internal thread 69, a clear inner dimension 70 being larger than the width 55 of the opening 53. The release element 57 in this exemplary embodiment is a preferably circularly formed recess 71 passing through the slide 45, the inside clear width 72 of which is larger than the clear inside dimension 70 of the holding element 56. It is also advantageous if the holding element forming the bore 68

56 and the release element 57 forming the recess 71 are aligned parallel to one another and perpendicular to the support surface 46 and the top surface 47 of the slide 45, since a parallel alignment of the needle arrangement with respect to the longitudinal central axis 12 of the receiving device 1 can be achieved in this way.

As can be seen better from the illustration in FIGS. 5 and 6, the retaining element 56 forming the bore 68 and the release element forming the recess 71 are

57 in the direction of the length 54 of the opening 53 arranged directly adjacent to one another in the slide, it being advantageous if the bore 68 and the

Recess 71 overlap in the direction of length 65 of opening 53. In order to achieve this overlap in the area of the opening 53, the center distance 67 between the bore 68 and the recess 71 can be less than half the sum of the clear dimension 70 of the bore 68 plus the inside clear width 72 of the recess 71. The larger the Center distance 67 between the

Bore 68 and the recess 71, the greater the displacement between the locked position and the release position and longer circular segments are formed in the area of the bore 68 and the recess 71, due to the longer circle segments in the area of the bore 68 a higher one Holding force for the insert element or the needle assembly 2 can be achieved. This also forms a smaller passage width between the bore 68 and the recess 71, which leads to an increase in the adjusting force.

As can now be seen better from FIGS. 4 and 5, at least one support surface 73, 74 is arranged on both sides of the parting plane 52 or on both sides of the opening 53 on the top surface 47 of the slide 45, which extends inclined to the top surface 47 over its longitudinal course is trained. In this case, a start 75 of the support surfaces 73, 74 is arranged in the region of the recess 71 or the release element 57 in the slide 45 and an end 76 of the same on the side facing away from the holding element 56 or the bore 68. The beginning 75 of the support surfaces 73, 74 is arranged to run approximately flat to the top surface 47, the end 76 of the same projecting above the top surface 47. Due to the inclined orientation of the support surface 73, 74 with respect to the top surface 47, these enclose an angle between 5 ° and 30 ° between them.

The opening 53 has end sections 77, 78 spaced apart from one another in the direction of the longitudinal extent, as a result of which the length 54 of the opening 53 in its longitudinal extension is limited. The interaction of the slide 45 with the receptacle 3, in particular the holding device 4 with the support elements 34, 35 and the mode of operation of the guide device 6 will be described in detail in one of the following figures.

7 and 8, the receiving device 1 with the needle arrangement 2 held thereon, the receiving container 3 and the actuating device 5 is shown in a schematically simplified, enlarged illustration, in FIG. 7 the blocking position for the needle arrangement 2 in the holding device 4, namely the holding element 56 is shown.

As already described above, the positioning element 19 is held on the cannula 18, and this can be designed in a wide variety of ways. In this exemplary embodiment, the positioning element 19 in the area of the holding element 56 formed by the bore 68 with the thread 69 has an extension 79 of opposite design, an external thread 80 being arranged on its outer surface. This external thread 80 is designed such that it interacts with the thread 69 or its threads in the bore 68, which is designed as a nut thread or internal thread, and can thus be screwed into the slide 45. The positioning element 19 further has, in the direct connection to the extension 79 on the side facing away from the receptacle 3, a projection 81 which projects beyond the extension 79 in the radial direction and limits the screw-in depth of the positioning element 19 with the cannula 18 held thereon and in this screwed-in state in comes to rest on the top surface 47 of the slide 45.

In this position of the receiving device 1 shown in FIG. 7, the center of the holding element 56 is aligned approximately centrally to the longitudinal central axis 12 of the receiving container 3. As already described above, the opening 17 is arranged in the end wall 10 of the receptacle 3 in the region of the longitudinal center axis 12, the two supporting elements 34, 35 being arranged on the end wall 10 of the receptacle 3 in the immediate vicinity of this opening 17. The two ends 36, 37 are spaced apart from one another in the direction of the parting plane 22 by the distance 38, the opening 35 having the greater length 54 in the same direction compared to this distance 38. Due to the central or congruent orientation or arrangement of the bore 68 of the holding element 56 in the slide 45 and the longitudinal central axis 12 or the opening 17, the opening 53 in the slide is Art designed that the first end portion 77 of the opening 53 is aligned in this position approximately adjacent to the end 37 of the support member 35.

The further end section 78 of the opening 53 is arranged at a distance 82 from the further end 36 of the support element 34. This distance 82 can be such that when the slide 45 is adjusted in the direction of an arrow 83, the slide 45 is moved from the locked position shown in FIG. 7 into the release position shown in FIG. 8 and therefore the positioning element 19 and thus the needle arrangement 2 comes from the holding element 56 in the slide 45 into the area of the release element 57, which is formed by the recess 71 in the slide 45, without a substantial transverse displacement of the needle arrangement 2 with respect to the receiving container 3 taking place. This transverse displacement of the needle arrangement 2 in the direction of the sliding movement of the slide 45 is prevented by the positioning of the positioning element 19 on one of the support surfaces 43, 44. Due to the previously described dimensional differences between the holding element 56 and the release element 57, a reliable release of the needle arrangement 2, in particular the one, takes place in a simple manner, due to the transverse adjustment of the slide 45 with respect to the receiving container 3 and possibly in cooperation with the guide device 6 Positioning element 19, from slide 45.

8 shows the release position of the slide 45 in relation to the receptacle 3, in which case the further end section 78 now comes to rest approximately at the further end 36 of the support element 34 and the first end section 77 of the opening 53 is spaced apart is arranged from the first end 37 of the support element 35.

During the adjustment movement of the slide 45 in the direction of the arrow 83 in relation to the receiving container 3, it can now be seen from a synopsis of FIGS. 4 to 8 that the attachment 81 of the positioning element 19 before the start of the adjustment process in the area of the beginning 75 of the Support surfaces 73, 74 is arranged and in the course of the adjustment process from the blocking position into the release position, the support surfaces 73, 74, which are inclined to the cover surface 47, bring about an additional detaching effect of the needle arrangement 2, in particular of the extension 79, from the holding element 56 and this results in one Movement of the entire needle assembly 2 in

Direction of a schematically entered arrow 84 on the direction of the slide 45 facing away from the receiving container 3 is achieved. This additional adjusting or releasing force in the direction of arrow 84 or in the direction facing away from the receptacle 3 additionally favors the release of the needle arrangement 2 from the release element 57, with a assisted release movement of the needle arrangement 2 being advantageously achieved when the needle tip of the cannula 18 points towards the earth, whereby this effect is increased by the force of gravity.

In order to prevent a relative adjustment of the needle arrangement 2, in particular of the positioning element 19 in relation to the receiving container 3 during the displacement process of the slide 45 in the direction of the arrow 83, the two previously described support elements 34, 35 with their support surfaces 43, 44 are on both sides of the opening 17 arranged, which prevent a relative displacement of the needle assembly 2 with respect to the receptacle 3 during the adjustment movement of the slider 45. As a result, it is now possible for the slide 45 to be moved from the locked position into the release position without the needle arrangement 2 being adjusted or displaced with respect to the receiving container 3.

FIGS. 9 to 12 show a further and possibly independent embodiment of the receiving device 1 in a simplified, schematic representation, the same reference numerals being used for the same parts as in FIGS. 1 to 8. For the sake of simplicity and in order to avoid unnecessary repetitions, reference is made to the description in the preceding figures for the formation and arrangement of individual parts or assemblies.

In this embodiment, the receiving device 1 consists of the receiving container 3 and the actuating device 5, which in turn is formed by the slide 45. Between the receptacle 3 and the actuating device 5, the guide device 6 described above is in turn arranged, which enables a relative adjustment of the actuating device 5, namely the slide 45, with respect to the receptacle 3 in a direction perpendicular to the longitudinal central axis 12.

The longitudinal center axis 12 is aligned centrally with respect to the container jacket 9, the opening 17 again being provided in the end wall 10 of the receiving container 3. In this embodiment, it is shown that the opening 17 has an approximately square cross section, in which the corner regions have a rounded transition. Both sides of the opening 17 are in turn in the area of Parting plane 22, the two support elements 34, 35 are arranged on the end wall 10 of the receptacle 3, which protrude beyond the end wall 10 or its surface 16 in the direction of the side facing away from the interior.

The interaction between the support elements 34, 35 with the needle arrangement 2, not shown here, in particular its positioning element 19, takes place analogously to that embodiment, as has already been described in detail in FIGS. 1 to 8.

In this exemplary embodiment, the slider 45 is in turn symmetrical to the parting plane 52 running in its longitudinal direction, the opening 53 being arranged in the parting plane 52 within the slider 45, which penetrates it in the direction of the longitudinal central axis 12. The holding device 4 is in turn arranged in the opening 53, part of the opening 53 forming the holding element 56 and another part forming the release element 57. The holding element 56 in the slide 45 is formed by the bore 68 with the internal thread 69 and has the clear internal dimension 70. Immediately adjacent to the holding element 56 is the release element 57, which here is formed by the preferably circular recess 71 that passes through the slide, the inner clear width 72 of the same being larger than the clear inner dimension 70 of the holding element 56.

It is also shown in this exemplary embodiment that the two support surfaces 73, 74 running parallel to the parting plane 52 are arranged in the immediate vicinity of the release element 57 and are arranged at a distance 85 from one another in the direction perpendicular to the parting plane 52. These two support surfaces 73, 74 in turn run at an angle to the top surface 47 of the slide 45.

The distance 85 between the two support surfaces 73, 74 is selected such that it is smaller than an outer dimension 86 - see FIG. 8 - of the extension 81 of the positioning element 19. Due to these dimensional differences, it is ensured that the side of the cover surface 47 facing the Approach 81 comes into contact with the two support surfaces 73, 74 at least in some areas on both sides of the release element 57, as a result of which the releasing action of the needle arrangement 2, in particular the positioning element 19, described above in FIGS. 1 to 8 during the relative adjustment movement of the slide 45 is related to the receptacle 3 is supported. Furthermore, in this exemplary embodiment of the receiving device 1 shown here, it is shown that between the receiving container 3 and the actuating device 5 a latching device 87, which is adjustable as required, is arranged, which detects the two positions of the slide 45 in relation to the receiving container 3 in the locked position and / or in the release division locked if necessary. This latching device 87 is formed from first latching elements 88, 89 which, in this exemplary embodiment, are arranged as spherical cap-shaped depressions in the surface 16 of the end wall 10. These two latching elements 88, 89 are each arranged at a distance 90 from one another symmetrically to the parting plane 22. As can be seen from the illustration in FIG. 11, these latching elements 88, 89, which are recessed in the shape of a spherical cap, are provided between the opening 17 and the guide elements 21 of the guide device 6. However, it is of course also possible to arrange these latching elements 88, 89, for example in the region of the guide elements 21. However, it is of course also possible to design the latching elements 88, 89 at a different location or in a different spatial shape than that shown and described here.

As can now be seen better from FIG. 9 and this has already been shown and described in detail in the previous FIGS. 4 to 6, the center of the holding element 56 is distanced from the center of the release element 57 by the center distance 67.

On the support surface 46 of the slide 45, opposite the locking elements 88, 89, further locking elements 91 are arranged, which in this exemplary embodiment are arranged at half the center distance 67 between the holding element 56 and the release element 57. The two locking elements 91 are arranged at a distance 92 from one another transversely to the parting plane 52, which distance corresponds to the distance 90 in the same direction between the individual locking elements 88, 89.

In order to achieve an exact positioning and alignment of the holding element 56 or the release element 57 with respect to the longitudinal central axis 12 or the opening 17, the latching elements 88, 89 are aligned in the region of the end wall 10 in a direction perpendicular to the parting plane 22 and parallel to the longitudinal central axis 12 Transverse plane in the direction perpendicular to the transverse plane or parallel to the parting plane 22 spaced apart from one another by a longitudinal distance 93, the dimensions of which correspond to the center distance 67 between the holding element 56 and the release element 57. Due to the dimensional selection and arrangement of the individual latching elements 88, 89, 91 relative to one another, an approximately central alignment of the holding element 56 with the opening 17 occurs when the latching elements 91 of the slide 45 engage with the latching elements 88 on the end wall 10 of the receptacle 3 . With a relative adjustment of the slide 45 in relation to the receiving container 3, the latching elements 91 disengage from the first latching elements 88 and, after a displacement movement in the direction of the parting plane 22 or in the direction perpendicular to the transverse plane, engage in the further latching elements 89 of opposite design , which in turn results in an approximately central alignment of the release element 57 with respect to the longitudinal central axis 12 or the opening 17. As a result of this adjustment movement and the different interlocking of the locking elements 91 on the slide 45 with the locking elements 88, 89 spaced apart from one another, there is a certain locking effect between the locking elements in the different positions, as a result of which the slide 45 is held in the respective relative position to the receiving container 3 or is set.

However, it is also possible, as is shown in a simplified representation in dash-dotted lines in FIG. 12, that at least a first latching element 88 on the surface 16 of the end wall 10 of the receiving container 3 in the edge region to the container jacket 9 and on the bearing surface 46 facing this of the slide 45, at least one further latching element 91 is arranged, wherein in the engaged position of the two latching elements 88, 91 there is a central or congruent alignment of the holding element 56 with the opening 17 or with the longitudinal central axis 12. In the release position, however, the two latching elements 88, 91 are disengaged and the latching elements 91 protrude beyond the outer surface 15 of the container casing 9 on the side facing away from the interior 11. This arrangement only locks the two locking elements 88, 91 in the locked position.

The opening 53 can be designed and arranged in relation to the support elements 34, 35 as in the previously described FIGS. 1 to 8. Furthermore, it is also advantageous if a longitudinal extension of the slide 45 in the direction of the opening 53 corresponds approximately to an outer dimension of the receptacle 3 in the region of its closed end region 8. As a result, a relatively flat angle between the body part and the receiving device 1 is achieved during the puncturing process for the removal of body fluids or the administration of medication or solutions. In addition, an unintentional unlocking of the needle assembly 2 from the receptacle 3 by an unwanted th adjustment process of the slider 45 prevented.

Of course, it is also possible, however, to determine the displacement path of the slide 45 with respect to the receptacle 3 - which corresponds at least to the center distance 67 between the holding element 56 and the release element 57 - for example only via the individual interlocking locking elements 88, 89 and 91. In addition, it is of course also possible to determine or limit the relative displacement between the slide 45 and the receptacle 3 by the choice of the length 54 of the opening 53 and the distance 38 between the ends 36, 37 of the support elements 34, 35. Of course, this relative displacement path can also take place through the mutually engaging guide elements 21 and 58, as has also already been described in FIGS. 1 to 8. Of course, any combination and multiple limitation of the displacement path are also possible from the previously described embodiments.

FIGS. 13 to 15 show a further and possibly independent embodiment of the receiving device 1, the same reference numerals being used for the same parts as in FIGS. 1 to 12. In order to avoid unnecessary repetitions here, reference is made to the description in the preceding FIGS. 1 to 12 for detailed configurations of individual parts or assemblies.

The receiving device 1 in turn consists of the receiving container 3 and the actuating device 5, between which in turn the guide device 6 is arranged. The design and arrangement of the guide elements 21 and 58 forming the guide device 6 can take place according to FIGS. 1 to 15. On the end wall 10 of the receptacle 3 there are in turn the support elements 34, 35 arranged in the parting plane 22, which support the positioning element 19 - see FIG. 1 - during the relative displacement process of the actuating device 5, namely the slide 45, in relation serve to the receptacle 3. The opening 17 in the end wall 10 is also in turn aligned centrally to the longitudinal central axis 12 of the receptacle 3. Of course, it is also possible to arrange the opening 17 and the two support elements 34, 35 eccentrically or eccentrically with respect to the receiving container 3 or the longitudinal central axis 12 if the needle arrangement 2 is not centered in relation to the approximately circular one here Container jacket 9 is desired. This arrangement can of course can be freely selected and depends on the respective application or area of application of the receiving device 1. It should be noted that the arrangement of the individual components is adjusted accordingly in relation to the extent of the displacement.

13 shows the blocking position between the slide 45 and the receptacle 3, in which the holding element 56 is aligned approximately centrally with respect to the longitudinal central axis 12 or the opening 17. In this so-called initial position or blocking position, it is possible to insert the insert element or the needle arrangement 2 into the holding elements 56 and also to hold it there. This insertion takes place due to the thread arrangement between the positioning element 19 and the holding element 56 by a simple screwing-in process. Of course, it is also possible, for example, to provide a corresponding snap connection or snap connection instead of this thread arrangement.

Furthermore, it is shown in simplified form in FIG. 13 that the latching device 87 is formed by latching elements 88 or 91 which can be brought into engagement with one another, at least one first latching element 88 on at least one of the guide surfaces of a guide element 21 and at least one further latching element 91 on at least a sliding surface of the recess 59, 60 facing this guide surface is arranged in the slide 45. The arrangement of the two locking elements 88, 91 relative to one another can be selected such that a central or congruent alignment of the holding element 56 with the opening 17 or the longitudinal central axis 12 is defined in the locking position of the locking elements 88, 91. Irrespective of this, however, any combination of the arrangements of the latching elements 88, 89, 91 described above is also possible. Thus, mutually associated latching elements 88, 89, 91 can be located between the outer surface 16 of the wall or end wall 10 and the bearing surface 46 of the slide 45 facing them and further mutually associated latching elements 88, 89, 91 between mutually facing guide surfaces 28 to 33 of the guide element 21 and sliding surfaces 61 to 64 of the indentations 59, 60 in the slide 45. The number and the alignment and arrangement of the individual latching elements 88, 89, 91 to one another can be chosen freely.

In this starting position or blocking position, the end section 77 of the slide 45 is aligned approximately abutting the end 37 of the support element 35 and at the same time the holding element 56 is also aligned centrally to the longitudinal central axis 12 or the opening 17. To prevent an unwanted displacement or adjustment of the slide 45 in to prevent receiving container 3, in this embodiment, a separate spring element 94 is arranged in the slide 45, which comes to rest here at the end 36 of the support element 34.

To form this spring element 94, the opening 53 on the side of the release element 57 facing away from the holding element 56 is enlarged in its cross section, the curved spring element 94 protruding into this opening. The arrangement and design of the spring element 94 within the opening 53 is not restricted to the spatial shape shown here and can of course have any spatial shape in order to achieve a sufficient locking force of the slide 45 in relation to the receiving container 3 in its initial position or locked position. Due to this applied spring force of the spring element 94 on the end 36 of the support element 34, there is a pressing force of the slide 45 in the region of the end section 77 in the direction of the end 37 of the support element 35.

If the slide 45 is now displaced in the direction of the arrow 83 relative to the receptacle 3, then due to the deformation of the spring element 94, a restoring force of the slide 45 in the direction of an arrow 95 is achieved, so that after the needle arrangement 2 is released, the spring is automatically reset

Slider 45 takes place in the starting position or blocking position. As a result, it is possible in a simple manner, immediately after reaching the release position in which the needle arrangement 2 or the insert element is released from the receiving device 1, that the slide 45 is automatically reset.

In this embodiment shown here, an opening 96 is additionally arranged on both sides of the parting plane 52 in the region of the opening 53 between the latter and the side surfaces 48, 49 in order to determine the necessary or to be applied to the slide 45 in the direction of the arrow 83, which also passes through the slide 45 in the direction of the opening 53. In this exemplary embodiment, the openings 96 extend in the longitudinal direction of the slide 45 approximately between the end section 77 and the end of the release element 57 facing away from this end section 77. This makes it possible to determine the adjusting force to be applied in the direction of the arrow 83 in which Due to the selection and size of the opening 96, a separate web 97 is formed between the opening 96 and the opening 17 in the region of the parting plane 52, has a variable web thickness 98 depending on the size of the opening 96, oriented to the parting plane.

Due to the different dimensions between the holding element 56 and the release element 57, the two webs 97 are oriented at an angle to one another, which enclose an acute angle between them, which tapers from the release element 57 towards the holding element 56 or the two webs 97 converge are aligned. Due to this arrangement of the opening 96, approximately the same web thickness 98 is achieved over the longitudinal extent of the webs 97. The smaller the web thickness 98 is selected, the lower the deformation force that must be applied in order to deform the two webs 97 transversely to the parting plane 52 or in the direction perpendicular to the latter. The transition from the holding element 56 to the release element 57 and the release of the positioning element 19 from the holding element 56 which is thus effected can thus be easily coordinated with one another, and the adjustment force can thus be predetermined and thereby increased or reduced. As a result, a larger or longer choice of the center distance 67 between the holding element 56 and the release element 57 is possible - as has already been described in FIGS. 5 and 6 -, as a result of which a better holding of the insert element or of the Positioning element 19 takes place.

As can now be seen better from FIGS. 14 and 15, it is additionally possible to arrange at least one recess 99 in the area of the support surface 46 of the slide 45, in order to reduce the size of the support surface 46 on the surface 16 of the end wall 10 . At the same time, however, a certain amount of material can be saved. However, in order to increase the full screw-in depth due to the arrangement of at least one recess 99 in the area of the support 46, it is possible to design the holding element 56 over the entire thickness of the slide 45. As a result, a support surface 46 is also formed in the area of the holding element 56 for support on the surface 16 of the end wall 10, as a result of the support in this area being supported on the end wall 10 and thus preventing deformation during the screwing-in process. Likewise, due to the greater screw-in depth over the full strength of the slide 45, a firmer and more secure mounting of the needle arrangement 2 is achieved during the intended use of the receiving device 1.

Furthermore, through the choice of the extent of the depression 99 and the weakening of the slide 45 associated therewith, the thickness of the webs 97 and also associated therewith also the necessary or to be applied deformation force for the adjustment process can be determined. The larger the size of the recess 99 is chosen, the smaller the thickness of the webs 97 in the direction perpendicular to the top surface 47.

In Fig. 15 it is further shown that on the support surface 46 of the slide 45 there is a projection 100 on the slide 45 which projects beyond the direction facing away from the cover surface 47 and which for the one-sided limitation of the displacement path during the adjustment process of the slide 45 is formed relative to the receiving container 3. The projection 100 is arranged and formed on the bearing surface 46 in the region of the side surface 50 in such a way that it comes to rest on the outer surface 15 of the container casing 9 in the release division of the slide 45 and thus ensures a further adjustment beyond the release position is prevented. Therefore, in the locked position of the slide 45, the projection 100 is arranged at a distance from the outer surface 15 of the container casing 9, this distance approximately corresponding to the center distance 67 between the holding element 56 and the release element 57. This design is advantageous in the arrangement of a spring element 94 within the opening 53, since excessive deformation and thus permanent plastic deformation or breakage of the same is also prevented. As a result, the necessary adjustment path between the blocking position and the release position corresponds approximately to the center distance 67 between the holding element 56 and the release element 57. As already described above, further limitation of the displacement or adjustment path can also be achieved by the guide elements which are in engagement with one another 21 or 58 of the guide device 6.

16 and 17 show a further and possibly independent design of a further receiving device 110, in particular for a needle arrangement 2 (not shown here in more detail) for taking off body fluids, tissue parts or tissue cultures, which comprises a receiving body, e.g. a receptacle 111 with a holding device 112 and an actuating device 113. In order to avoid unnecessary repetition, the same component designation as in the previous FIGS. 1 to 15 is used in the description for the same components.

The receptacle 11 of the receptacle 110 has end regions 114, 115 spaced apart from one another, between which a container jacket 116 extends. The first end region 114 is open and the further end region 115 is closed design, an end wall 117 being arranged in the end region 115. Due to the arrangement and design of the container jacket 116 in connection with the end wall 117, these enclose an interior 118, in this exemplary embodiment a longitudinal central axis 119 extending approximately centrally to the container jacket 116 between the two end regions 114, 115 facing away from one another.

In this exemplary embodiment, the actuating device 113 is formed by an approximately annular slide 120, the dimensions of which are such that an internal clear dimension thereof roughly corresponds to an outer dimension of the container shell 116. This makes it possible for the slider 120 to be adjustably supported along an outer surface 121 of the container casing 116 in the direction of the longitudinal central axis 119 along the latter. This requires an approximately cylindrical or with the same dimensions to the longitudinal central axis 119 in the direction of the container jacket 116 formed. In the region of the end wall 117, a stop 122 arranged at least partially over the circumference projects beyond the outer surface 121 in the direction facing away from the longitudinal central axis 119. Due to this arrangement of the stop 122, an undesired release of the slide 120 from the receptacle 111 is prevented.

Furthermore, the receiving device 110 in the region of the end wall 117 has the holding device 112 for a needle arrangement (not shown here), which in this exemplary embodiment is formed by a holding element 123 of approximately circular design. The holding element 123 preferably has a bore 124, which is centered on the central longitudinal axis 119 and has a thread 125 in the form of a nut thread or internal thread. This makes it possible to screw the needle assembly into the holding element 123 by means of a screwing movement and to hold it in this screwed-in position.

17, the actuating device 113 in the form of the slide 120 is shown in full lines in the locked position and in the dashed position in the release position for the needle arrangement, the release division being shown only for the possible position of the slide, without one possible deformation caused by the adjustment process. The blocking position is the position in which the slide 120 is aligned approximately abutting the stop 122 in the region of the end wall 117. According to an entered double arrow 126, the sliding movement of the slide 120 takes place from the locked position into the release division shown in dashed lines, in which one The needle assembly is released from the holding device 112 and then the same is returned to the locked position.

16 and 17 can be seen, the end wall 117 is divided into several, in this embodiment in three end wall parts 127 to 129, this division being formed by slot-shaped openings 130 in the end wall 117. In this exemplary embodiment, the slot-shaped openings 130 are offset from one another in a plane oriented perpendicular to the longitudinal central axis 119 by an angle of approximately 120 ° to one another, but this size of the angle depends on the number of end wall parts. With a symmetrical distribution of the end wall parts 127 to 129 and the angle between the slot-shaped openings 130, this angle is calculated by dividing the full circle by the number of end wall parts. It is possible to form at least two, but preferably several end wall parts. This slot-shaped opening 130 also divides the holding element 123 into a number of holding element parts 131 to 133 corresponding to the number of end wall parts 127 to 129, which thus form circular ring segments with an internal thread.

The slot-shaped openings 130 extend from the closed end region 115 or the end wall 117 in the direction of the open end region 114 in the direction of the longitudinal central axis 119 over a length 134. Furthermore, in this exemplary embodiment, FIG. 17 shows that the slot-shaped one Opening 130 in the container jacket 116, starting from the end wall 117 in the direction of the end region 114, is designed to taper towards one another, the length 134 of the opening 130 being arbitrary and being dependent on the opening amount of the holding element parts 131 to 133 to be achieved with respect to the longitudinal central axis 119.

Furthermore, it is shown here that actuating elements 135 are arranged on the inner surface of the slide 120 in equal number and equal pitch angle with respect to the slot-shaped openings 130, which protrude beyond the inner surface of the slide 120 in the direction of the longitudinal central axis 119. Due to this protrusion or protrusion of the individual actuating elements 135, they engage in the slot-shaped openings 130, which due to the likewise wedge-shaped design of the same during the adjustment process in the direction of the double arrow 126, starting from the locked position, widening in the release division Breakthroughs 130 takes place. The individual foreheads Wall parts 127 to 129 with the holding element parts 131 to 133 connected to them and the wall parts 136 to 138 formed in the region of the container shell 116 between the openings 130 arranged in regions over the circumference are elastically deformed and adjusted in the direction of schematically indicated arrows 139. This expansion process, due to the sliding movement of the slide 120 starting from the locked position in the release division, results in a central expansion of the holding element 123 with respect to the longitudinal central axis 119, as a result of which the individual holding element parts 131 to 133 with their internal threads disengage from the positioning element (not shown here) 19 of the needle arrangement 2 come.

When the receiving device 110 is in a downward position, in which the needle tip points in the direction of the floor and thus the weight or gravity acts on the needle arrangement, the needle arrangement is easily released from the receiving device 110 The manner in which the slide 120 moves from the locked position to the release position enables the held needle assembly to be released, and after the slide 120 is reset to the locked position, the needle assembly 2 is screwed into the receiving device 110 again can be done.

18 and 19 show a further and possibly independent design of another receiving device 110, which is used in particular for a needle arrangement 2 (not shown here) for taking off body fluids, tissue parts or tissue cultures, and a receiving body, e.g. a receptacle 11 and a holding device 112. In order to avoid unnecessary repetitions, the same component designation as in the previous FIGS. 1 to 17 is used in the description for the same components.

The receptacle 111 has end regions 114, 115 spaced apart from one another, between which a container jacket 116 extends. Again, the first end region 114 is open and the further end region 115 is closed, the end wall 114 closing the end region 115. A longitudinal center axis 119 extends approximately centrally to the container jacket 116 between the two end regions 114, 115 which face away from one another.

As already described above, the receiving device 110 has in the area of the End wall 117, the holding device 112 for a needle arrangement 2, not shown here, which is formed in this embodiment by an approximately circular-shaped holding element 123. The holding element 123 preferably has a bore 124, which is centered on the central longitudinal axis 119 and has a thread 125 in the form of a nut thread or internal thread. This in turn makes it possible to screw the needle assembly 2 into the holding element 123 by means of a screwing movement and to hold it in this screwed-in position.

As can now be seen from an overview of FIGS. 18 and 19, in the area of the end wall 117, parallel to this or in a plane oriented perpendicular to the longitudinal central axis 119, a swivel axis 140 is arranged or formed on both sides of the holding element 123, which pivot extends between the outer periphery of the receptacle 111 and the outer periphery of the holding member 123. In this exemplary embodiment, the two pivot axes 140 are aligned concentrically or coaxially with one another, as a result of which an approximately aligned arrangement of the two pivot axes 140 is formed in the longitudinal direction. The two swivel axes 140 facing one another form, in conjunction with the longitudinal center axis 119, a division plane 141 running therethrough, in which, within the holding device 112, starting from the swivel axes 140, slot-shaped openings 142 in the holding element 123 extend in the direction facing away from the interior 118 are arranged. These slot-shaped openings 142 subdivide the holding element 123 into a holding element part 131 or 132 arranged on both sides of the division plane 141. The pivot axes 140 can be designed in very different ways and e.g. be realized by joints, hinges, material weakening, etc.

As is now shown in FIG. 18, in the intersection of the parting plane 141 with the container jacket 116 there is a recess 143 passing through it in each case, which has a different width over its longitudinal course, starting from the closed end region 115 towards the open end region 114 perpendicular to the division plane 141. The width, starting from the division plane 141, preferably increases over a first partial region of the recess 143 and, after a certain distance from the end region 115, the width of the recess 143 is designed to decrease. This recess 143 serves to take advantage of the elastic deformation properties of the receptacle 1 1 1 and, as shown in FIG. 20, the container jacket 1 16, due to the arrangement of the recess 143, by applying a compressive force, as is shown schematically by Arrows 144 is shown to deform it in such a way that the two holding element parts 131, 132 can be adjusted relative to one another about the pivot axes 140 and an opening movement of the holding device 112 takes place.

This application of the pressure force according to the arrows 144 is preferably carried out in the direction perpendicular to the division plane 141, as a result of which, due to these forces, the recesses 143 arranged on both sides in the container jacket 116 are also deformed, as a result of which the two holding element parts 131, 132 in their, from Interior 1 18 facing away, end region are moved away from each other and thereby an enlargement of the bore 124 is achieved. In this way, a release of a needle arrangement 2 held in the holding device 112 is achieved in a simple manner.

FIGS. 21 to 23 show another and possibly independent embodiment of a receiving device 110 in a simplified, schematic representation, the same reference numerals being used for the same parts as in the previous FIGS. 1 to 20. For the sake of simplicity and to avoid unnecessary repetitions, reference is made to the description in the preceding figures for the formation and arrangement of individual parts or assemblies.

In this exemplary embodiment shown here, the entire representation of the receptacle 11 1 has been dispensed with, since its detailed design, in particular in the region of the open end region 1 14, is not of importance for the invention. In the section of the end region 115 of the receptacle 111, the end wall 117 is arranged in the plane 20 oriented perpendicular to the longitudinal central axis 119, which, in cooperation with the container jacket 116, delimits the interior 118 of the receptacle 111. An opening 145 passing through the end wall 117 is arranged centrally to the longitudinal center axis 119. This has a clear inner dimension, which corresponds to at least one outer dimension of a positioning element 19 of the needle arrangement 2 shown in simplified form. Furthermore, in the area of the closed end area 115, the receiving device 110 comprises a holding device 146 for the schematically simplified positioning element 19 of the needle arrangement 2, which, in this exemplary embodiment, has an adjusting element 147 which extends over the container jacket 116 at least in some areas, and a plurality of the end wall 11 to the interior 1 18 opposite direction protruding guide elements 148 and the guide elements 148 associated and interacting with the adjusting member 147 includes holding elements 149. In this exemplary embodiment, guide elements 148 assigned to one another are arranged several times over the circumferential area of the end wall 117 in the plane 20 oriented perpendicular to the longitudinal central axis 119, a division angle 150 being formed between guide elements 148 assigned to each other. In the exemplary embodiment shown here, each of the holding elements 149 is assigned two guide elements 148 oriented parallel to one another on both sides, the pitch angle 150 between the holding elements 149 or the guide elements 148 assigned to them being divided by the division of the full circle in plane 20 by the number of holding elements 149 calculated. In the exemplary embodiment shown here, the pitch angle 150 is 120 °, as a result of which a symmetrical division of the individual holding elements 149 from one another is formed. The guide elements 148 arranged on both sides of the holding element 149 represent a type of guiding device for the holding element 149 arranged between them and each enable the holding elements 149 to be adjusted in accordance with a double arrow 151 entered in a direction perpendicular to the longitudinal central axis 119 and parallel to the plane 20.

21 and 23, the blocking position of the holding elements 149 for the positioning element 19 of the needle arrangement 2 is shown in simplified form, whereas, in FIG. 22, the release position or opening position of the individual holding elements 149 is shown. In this exemplary embodiment, the adjusting member 147 is approximately cap-shaped and has an inner clear dimension in the form of an inner diameter with respect to the longitudinal central axis 119, which corresponds to at least one outer diameter of the container shell 116 in the section of the end region 115. As a result, a cylindrical wall part 152 of the adjusting member 147 of the container jacket 116 can be overlapped at least in regions. Furthermore, in the direction parallel to the end wall 117 of the receptacle 111 or in the direction parallel to the plane 20, the adjusting member 147 has a further end wall 153 connecting the cylindrical wall part 152, which also has a further opening 154 centrally to the longitudinal central axis 119.

The dimensions of an inner clear dimension or an inner diameter of the opening 154 can correspond to the opening 154 in the end wall 117, but it is of course possible to make the opening 154 larger. It can prove to be advantageous if the opening 154 has a clear dimension which corresponds to the outer dimension 86 of the extension 81 of the positioning element 19 shown in FIG. 8 or is selected to be larger. This makes it possible for the shoulder 81 comes to rest on a surface 155 of the holding element 149 facing away from the end wall 117 in the screwed-in position and in the locked position of the holding elements 149. Of course, however, it is also possible to design the inside dimension to be approximately the same or smaller than the opening 145, so that when the holding elements 149 are in the blocking position, the shoulder 81 of the positioning element 19 bears against the outer surface of the end wall 153.

To adjust the individual holding elements 149, starting from the locked position into the release division, the adjusting member 147 is pivotally or rotatably mounted on the container jacket 116 with respect to the longitudinal central axis 119. Due to the arrangement of the guide elements 148 projecting beyond the end wall 117 and the arrangement of the holding elements 149 chosen between the end wall 117 of the receptacle 11 1 and the end wall 153 of the adjusting member 47, it is possible to move the adjusting member 147 by a corresponding pivoting or rotating movement relative to the Receiving container 111 according to an arrow 156 to achieve an adjustment of the holding elements 149 from the release division shown in FIG. 22 into the locking position shown in FIG. 23 and then back again into the locking position.

In order to enable the adjustment of the holding elements 149 from the release position into the blocking position or vice versa, each of the holding elements 149 has at least one adjusting element 157 which projects above the surface 155 and which has an actuating element 157 in the end wall 153 on the end wall 117 of the receptacle 111 facing side is in drive connection with a groove-shaped recess 158 arranged recessed therein. This groove-shaped depression 158 or backdrop has a different distance from the longitudinal central axis 119 over its longitudinal course, which serves to effect the adjustment of the individual holding elements 149 according to the double arrows 151 in cooperation with the guide elements 148.

On the side facing the positioning element 19, each of the holding elements 149 has at least a partial area of an internal thread, wherein in the locked position of the holding elements 149 it is possible to screw the positioning element 19 of the needle arrangement 2 properly. Furthermore, by selecting the distance of the groove-shaped recess 158 with respect to the longitudinal central axis 119, the extent of the adjustment path and thus also the adjustment speed, due to the selected slope of the curve, can be determined for the holding elements 149. It has proven to be advantageous if the first section of the groove-shaped depression 158 has a relatively large slope or increasing and increasing distance from the longitudinal center Axis 1 19 is selected, since a rapid opening movement of the individual holding elements 149 is achieved and the positioning element 119 and thus the needle arrangement 2 are already released after a short adjustment path in the form of a turning operation of the adjustment member 147.

In order to prevent unintentional detachment of the adjusting member 147 from the receiving container 111, it is possible to arrange a securing device 159 between the wall part 152 of the adjusting member 147 and the container jacket 116 of the receiving container 111, which on the one hand pivots or rotates the adjusting member 147 relative to the receiving container 111 allows and on the other hand, the adjusting member 147 in the direction of the longitudinal central axis 1 19 immovably on the receptacle 111. This ensures that an equal distance or an equal distance is always maintained or fixed between mutually facing surfaces of the end wall 11 of the receptacle 111 and the end wall 153 of the adjusting member 147. This securing device 159 can be formed, for example, by at least one annular or groove-shaped depression formed in the container jacket 116 and at least one projection or projection on the wall part 152 of the adjusting member 147 which cooperates with and engages in this groove-shaped depression. This groove-shaped recess can also be arranged, for example, only partially in the container jacket 116 over its longitudinal course in the direction of the circumference, a length of this groove-shaped recess of the securing device 159 being able to correspond to the adjustment path of the adjusting member 147 relative to the receiving container 111. This makes it possible in a simple manner, due to the length of the groove-shaped depressions, to determine exact end stops both for the locking position and for the release division.

However, it is also possible to form the groove-shaped recess of the securing device 159 continuously over the circumference of the container shell 116, which enables an unimpeded rotational movement of the adjusting member 147 relative to the receiving container 111. The locking and release position can be determined, for example, over the length of the groove-shaped recesses 158 in the end wall 153 of the adjusting member 147. In this embodiment described here, the securing device 159 only serves to hold the adjusting member 147 in a predeterminable position on the receiving container 11 in the direction of the longitudinal central axis 119.

If, for example, the securing device 159 is covered by a 23, it is also possible, as is shown in simplified form in FIG. 23, to additionally arrange a separate limiting device 160 between the adjusting member 147 and the receiving container 111, which limits the two end positions between the adjusting member 147 and the receiving container 1 1 1 serves in connection with the holding elements 149. Again, at least one, but preferably a plurality of groove-shaped recesses extending over a partial region of the circumference can be formed in the container jacket 116, a length of which corresponds to the relative adjustment path between the adjustment member 147 and the receiving container 111. A projection or projection engages in this groove-shaped recess, which defines either the blocking position or the release division in the respective end position. An angle of approximately 90 ° has proven to be the preferred angle of rotation between the adjusting member and the receptacle 111. Of course, smaller or larger angles of rotation are also possible. With a selection of approx. 90 ° for the angle of rotation, simple one-hand operation is possible for the adjustment from the locked position to the release division and back again.

It has been found to be advantageous and necessary if the materials used for the receiving device 1 can be steam sterilized. For example, 3 polypropylene (PP) and for the slide 45, 120, the adjusting element 147 and the holding elements 149 polyoxymethylene (POM) can be used as the material for the receiving body or the receiving container. In addition, the material of the slider 45 should also have a higher hardness than the insert element or the positioning element 19. This reduces or prevents damage and wear of the slider 45 over a longer period of use.

FIGS. 24 and 25 show a further embodiment of the receiving device 1, which is possibly independent of its own, again using the same reference numerals for the same parts as in FIGS. 1 to 15. In order to avoid unnecessary repetitions here, reference is made to, or reference to, the description in the preceding FIGS. 1 to 15 for detailed configurations of individual parts or assemblies.

The receiving device 1 in turn consists of the receiving container 3 and the actuating device 5, between which in turn the guide device 6 is arranged. The design and arrangement of the guide elements 21 and 58 forming the guide device 6 can take place according to FIGS. 1 to 15. On the forehead Wall 10 of the receptacle 3, in turn, the support elements 34, 35 arranged in the parting plane 22 are provided, which are used to support the positioning element 19 - see FIG. 1 - during the relative displacement process of the actuating device 5, namely the slide 45, with respect to the receptacle 3 serve. The opening 17 in the end wall 10 is also in turn aligned centrally to the longitudinal central axis 12 of the receptacle 3. Of course, it is also possible to arrange the opening 17 and the two support elements 34, 35 eccentrically or eccentrically with respect to the receiving container 3 or the longitudinal central axis 12 if the needle arrangement 2 is not centered in relation to the container jacket 9, which is of approximately circular design here is desired. This arrangement can of course be chosen freely and is dependent on the respective application or field of application of the receiving device 1. It should be noted that the arrangement of the individual components is adjusted accordingly in relation to the extent of the displacement.

24 shows the blocking position between the slide 45 and the receptacle 3, in which the holding element 56 is aligned approximately centrally with respect to the longitudinal central axis 12 or the opening 17. In this so-called initial position or blocking position, it is possible to insert the insert element or the needle arrangement 2 (not shown for the sake of clarity) into the holding elements 56 and also to hold it there. This insertion takes place due to the thread arrangement between the positioning element 19 and the holding element 56 by a simple screwing-in process. Of course, it is also possible, for example, to provide a corresponding snap connection or snap connection instead of this thread arrangement.

In the starting position or blocking position shown here, the end section 77 of the slider 45 is aligned approximately abutting the end 37 of the support element 35 and at the same time the holding element 56 is also aligned centrally to the longitudinal central axis 12 or the opening 17. In order to prevent an undesired displacement or adjustment of the slide 45 in relation to the receptacle 3, in this exemplary embodiment a separate spring element 94 is arranged in the slide 45, which comes into contact here at the end 36 of the support element 34.

To form this spring element 94, the opening 53 on the side of the release element 57 facing away from the holding element 56 has an enlarged cross section, the curved spring element 94 being formed in this opening protrudes. The arrangement and design of the spring element 94 within the opening 53 is not tied to the spatial shape shown here and can of course have any spatial shape in order to achieve a sufficient locking force of the slide 45 in relation to the receptacle 3 in its initial position or locked position and around on the other hand to ensure a simple adjustment movement with sufficient resetting. Due to this applied spring force of the spring element 94 on the end 36 of the support element 34, there is a pressing force of the slide 45 in the region of the end section 77 in the direction of the end 37 of the support element 35.

However, it is also possible that the spring element 94 is designed such that in the initial position or locked position of the slide 45 with respect to the receptacle 3 it is almost undeformed and thus comes into contact with the end 36 of the support element 34 without applying any spring force and Only when the adjustment is made in the release division, due to the deformation of the spring element 94, is a spring force built up which causes the slide to be reset after the needle arrangement 2 has been released into the starting position or into the blocking position. As a result, it is possible in a simple manner that, immediately after reaching the release position, in which the needle arrangement 2 or the insert element is released from the receiving device 1, the slide 45 is automatically reset.

In this embodiment shown here, the opening 96 is additionally arranged in the slide 45 on both sides of the parting plane 52 in the region of the opening 53 between the latter and the side surfaces 48, 49 in order to determine the necessary or to be applied to the slide 45 in the direction of the arrow 83, which also passes through the slide 45 in the direction of the opening 53. In this exemplary embodiment, the openings 96 extend in the longitudinal direction of the slide 45 approximately between the end section 77 (see FIG. 5) and the end of the release element 57 facing away from this end section 77. This makes it possible to apply the adjusting force in the direction of the arrow 83 To be defined, in which, due to the selection and size of the opening 96, a separate web 97 is formed between the latter and the opening 17 in the region of the parting plane 52, which is arranged in a direction approximately perpendicular to the parting plane depending on the size of the Opening 96 has a variable web thickness 98 (see FIG. 14).

Due to the different dimensions between the holding element 56 and the release element 57, the two webs 97 are oriented at an angle to one another, wherein they enclose an acute angle between them, which tapers from the release element 57 to the holding element 56 or the two webs 97 are aligned toward one another. Due to this arrangement of the opening 96, approximately the same web thickness 98 is achieved over the longitudinal extent of the webs 97. The smaller the web thickness 98 is selected, the lower the deformation force that must be applied in order to deform the two webs 97 transversely to the parting plane 52 or in the direction perpendicular to the latter. The transition from the holding element 56 to the release element 57 and the release of the positioning element 19 by the holding element 56 which is thus effected can thus be easily coordinated with one another and the adjustment force can thus be predetermined and thereby increased or reduced. As a result, a larger or longer choice of the center distance 67 between the holding element 56 and the release element 57 is possible - as has already been described in FIGS. 5 and 6 -, as a result of which a better holding of the insert element or of the Positioning element 19 takes place.

Furthermore, it is additionally possible to arrange at least one recess 99 in the region of the support surface 46 (see FIG. 4) of the slide 45, in order to reduce the size of the support surface 46 on the surface 16 of the end wall 10. At the same time, however, a certain amount of material can be saved. However, in order to increase the full screw-in depth due to the arrangement of at least one recess 99 in the area of the support surface 46, it is possible to design the holding element 56 over the entire thickness of the slide 45. As a result, a support surface 46 for support on the surface 16 of the end wall 10 is also formed in the region of the holding element 56, as a result of which the support in this region is supported on the end wall 10 and thus prevents deformation during the screwing-in process is. Likewise, due to the greater screw-in depth, the full strength of the slide 45 results in a firmer and more secure mounting of the needle arrangement 2 during the intended use of the receiving device 1.

Through the choice of the extent of the depression 99 and the weakening of the slide 45 associated therewith, the thickness of the webs 97 and, in connection therewith, also the necessary or to be applied deformation force for the adjustment process can be determined. The larger the size of the recess 99 is selected, the smaller the thickness of the webs 97 in the direction perpendicular to the top surface 47. Likewise, on the contact surface 46 of the slide 45, this can be adapted to that of the top surface 47. opposite direction projecting projection 100 may be arranged on the slider 45.

24 and 25, a locking device 161, which can be released as required, is arranged between the slide 45 and the wall or end wall 10 of the receptacle 3, which is on both sides, in particular centered on the parting plane 52 and on both sides of the Opening 17 is arranged. However, it is of course also possible to arrange the locking device 161 only on one of the two sides of the parting plane 52. In the case of a symmetrical arrangement of the locking device 161, it has a plurality of locking elements 162 - two locking elements 162 in the exemplary embodiment shown here - which are arranged on the wall or end wall 10 of the receptacle 3 on the side facing away from the interior 11 and the wall or end wall 10 protrude to the side facing away from the interior 11. These two locking elements 162 are arranged in a normal plane 163 running perpendicular to the parting plane 22 and through the longitudinal central axis 12. These locking elements 162 are arranged on the wall or end wall 10 of the receptacle 3 in such a way that they protrude into the openings 96 of the slider 45 and at least on side surfaces 164 of the webs 97 facing away from the opening 53 in the locked position between the slider 45 and the receptacle 3 concern in some areas.

In the locked position, the holding element 56 is aligned approximately centrally to the longitudinal central axis 12, as a result of which the needle arrangement 2 can be screwed into the slide 45. To achieve sufficient lateral stability of the two webs 97 in conjunction with the variable web thickness 98, it is possible for the two webs 97 to deform elastically, as a result of which the holding element 56 can be expanded and the needle arrangement 2 is no longer securely held. This widening takes place approximately in the normal plane 163. In order to enable a corresponding adjustment movement of the slide 45 relative to the receptacle 3 according to the arrow 83, the formation and inclination of the side surfaces 164 of the webs is required when the locking elements 162 are arranged on the end wall 10 97 to be taken into account in order to be able to carry out a corresponding adjustment movement without obstructing the same.

In the embodiment shown here, it is necessary, due to the inclined side surfaces 164, that further locking elements 165 are also arranged on these, which, in the locked position, interact with the locking elements 162 on the receptacle 3 and thus form the locking device 161. These further locking elements 165 project beyond the side surfaces 164 on the opening 53 opposite side and protrude into the openings 96 of the slide 45. Due to the conically tapering side surfaces 164, the protrusion of the further locking elements 165 over the side surfaces 164 is to be selected such that when the slide 45 is moved from the blocking position into the release division, the locking elements 162 no longer come into contact with the side surfaces 164 Concerns are only possible in the approval department.

The interaction of the locking elements 162 with the further locking elements 165 in turn prevents the holding element 56 from expanding in the blocking position, as a result of which secure securing or fixing of the needle arrangement 2 is ensured during the intended use of the receiving device 1. Due to this arrangement of the cooperating locking elements 162 with the further locking elements 165, the locking device 161 is engaged in the locked position of the slide and disengaged in the release division.

Of course, it is also possible, as has also been simplified here and has already been described in detail in the previous FIGS. 1 to 15, to arrange the support surfaces 73, 74 accordingly on the cover surface 47.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the receiving device, in particular the holding device, this or its components have been partially shown to scale and / or enlarged and / or reduced.
