Description

Pick-up device with adjustable cover element

The invention relates to a receptacle with an elongated, outer receptacle for a receptacle, in particular a blood sample tube, the receptacle with a container wall delimiting a receptacle chamber and having a proximal and a distal end at a distance from one another in the direction of a longitudinal axis, and the receptacle wall through the inner surface facing the receiving chamber and an outer surface facing away from it is limited, with a needle carrier for a needle arrangement which can be held thereon, in particular a double-ended cannula, the needle carrier in the receiving chamber of the receiving container relative to the latter as required, from an insertion position in the area of the proximal end Is designed to be displaceable in the direction of the distal end into a disposal position, with a first adjusting device for the needle carrier for the necessary displacement from the inserted position into the Disposal position, with a cover element for the needle arrangement that can be held on the needle carrier in the disposal position of the needle carrier.

US Pat. No. 5,810,775 A discloses a receiving device for medical blood sampling tubes, in which, by pivoting the closure element relative to the receiving container, an adjusting element arranged in its receiving chamber is adjusted in the direction of the longitudinal axis towards the proximal end by adjusting elements provided on the closing element is released, whereby the needle carrier held in the region of the proximal end is released from its clamped seat in the adjusting element and, after being released, is returned to the interior of the receiving device together with the needle arrangement by a prestressed spring element. Due to the pivoting movement of the closure element, in this embodiment, on the one hand, a longitudinal adjustment of the adjusting element in the direction of the longitudinal axis and, on the other hand, after the needle carrier has been triggered or unlocked from the adjusting element, the interior of the receiving device is closed, thereby preventing the operator from contacting the needle arrangement , The disadvantage of this embodiment is that the connection between the needle carrier and the adjusting element in the form of a clamp seat is very complex and complex to carry out, on the one hand to achieve a sufficient tight fit for the removal process and on the other hand the trigger force required for unlocking this connection is not too high choose. In addition, because of the Spring pretensioning of the needle carrier in the event of an unintentional loosening of the clamping connection between the needle carrier and the adjusting element, due to the rapid return of the needle into the interior, there is a high risk of injury for the user of this receiving device.

Another receiving device for blood sampling devices is known from US 5,769,826 A and WO 98/41249 AI, in which a needle carrier biased by a spring is held locked in the receiving container by a slide in the use position and after the intended removal process the locking between the Slider and the needle carrier can be released, whereby this is reset due to the spring preload together with the needle arrangement in the interior of the receiving device. If necessary, the distal end of this receiving device can be closed by a closure element pivotably arranged on the receiving container. The disadvantage here is that when the slide is actuated and the associated return movement occurs due to the spring prestressing force, the needle carrier is jerked back into the interior, with the risk of a puncture injury for the operating personnel when the cover or closure element is not closed.

From document US 5,407,436 A and WO 93/23098 AI, a receptacle with a holding device for a needle carrier and a double needle inserted therein has become known, the needle holder equipped with the double needle automatically entering the inside of the holding device of the holding device after loosening a retaining device in the receiving chamber is retractable. The needle holder is held in place by fixing elements in an end region of the receptacle, a compressed and thus pre-tensioned spring being arranged between the end face and the needle holder, which exerts a force directed parallel to the longitudinal axis of the receptacle on the needle holder. This force pushes the needle holder against the retaining lugs of several fixing elements. The fixing elements are designed as finger-like extensions of the receptacle directed parallel to the central longitudinal axis and are arranged such that they surround a disk-shaped part of the needle holder on its circumference and their holding lugs directed inwards towards the central longitudinal axis as far as over the edge of this disk-shaped part of the Protect the needle holder so that it is held against the action of the spring. A is used to trigger the automatic needle retraction tubular plunger, which has an outwardly facing, truncated cone-shaped bevel at its end region to be inserted into the receptacle of the holding device. If this plunger is now pushed into the holding device so that the frustoconical bevel comes into operative connection with the holding lugs, the fixing elements with the holding lugs are pressed apart on the side facing away from the longitudinal axis, thereby releasing the needle carrier and, due to the spring force, into the receiving chamber is adjusted. The disadvantage here is that a separate component is necessary for triggering and a one-hand operation is not possible.

Another removal device has become known from US Pat. No. 5,423,758 A or WO 95/16389 AI, in which the removal needle together with the needle carrier is held in an adjusting sleeve and is surrounded by a further protective sleeve, so that the removal needle is completely protected from the removal process. A spring device is arranged between the needle carrier and the outer protective sheath. The needle carrier is held in the adjustment sleeve by means of a clamp fit, whereby for the intended

Use the adjusting sleeve relative to the outer protective sleeve and subsequently the spring device is biased. At the same time, one end of the removal needle protrudes over the protective cover, in which case the intended removal process can then be carried out. The distances or limit stops are between a handle arranged on the adjusting sleeve and the one that interacts with it

Protective cover coordinated in such a way that the spring device is only pre-tensioned for the intended removal process to such an extent that the needle carrier is not loosened firmly in the adjusting sleeve. In this position there is a mutual locking between the protective sleeve and the adjusting sleeve in order to avoid another pulling apart between them. In the course of the removal process, the handle which can be displaced on the adjusting sleeve is moved into a further position distanced from the protective sleeve, whereby due to this spacing, a further relative displacement between the protective sleeve and the adjusting sleeve can take place, and thus the tight fit of the needle carrier takes place via the prestressed spring device and after Loosening this tight fit the resetting of the needle carrier into the interior of the adjusting sleeve takes place. The disadvantage here is that a large number of adjustment processes must be carried out between the individual components of the receiving device in order to ensure proper functioning. Likewise, an intervention into the interior of the adjusting sleeve is still possible, which makes it undesirable Sting injuries can occur for the operating personnel.

A further safety acceptance device has become known from US 2002/0099355 AI, in which the entire needle carrier with the angularly designed puncture needle for the blood sample collection tube can be reset by the operator in a separate longitudinal guide from the use position to the disposal position. The disadvantage here is that, once again, an intervention into the interior of the receiving device is possible in the disposal position.

The present invention has for its object to provide a pick-up device in which, after the intended use, an adjustment movement of the needle carrier into the interior of the pick-up device which can be triggered by the operator is possible when the interior is automatically closed against unwanted intervention towards the reset removal needle.

This object of the invention is achieved in that the cover element in the inserted position of the needle carrier is arranged adjacent to it on the side facing away from the proximal end in the receiving chamber and is held relative to the latter in the inserted position with a releasable latching device between the cover element and the receiving container and a further adjustment device is arranged between the needle carrier and the cover element, the cover element being adjusted in the direction of the distal end of the receptacle by the further adjustment device when the latching device is released. The surprising advantage that results from this is that the immediate adjacent arrangement of the needle carrier and the cover element within the receptacle means that the entire receptacle is ready for use for the intended use without any preparatory work and that the respective operator triggers the latching device by means of one-hand operation can be. This can be done very simply by arranging the locking device on the receptacle through the pre-tensioned and locked cover element in cooperation with the likewise pre-tensioned needle carrier. On the one hand, this ensures safe operation and, after completion of the removal process, a secure closure of the interior by the cover element for the cannula end facing the interior or the distal end. This is an unintentional reach into the interior and thus prevent an unwanted puncture injury, which greatly reduces the risk of infection for the operating personnel or avoids it at all. At the same time, however, this also creates a cost-effective receiving device which is sufficient with a small number of components and at the same time offers high operational reliability.

A further embodiment according to claim 2 is also advantageous, since as a result the needle carrier can still be safely returned to its disposal position even after a longer storage period, thus ensuring high operational reliability.

A design according to claim 3 is also advantageous, since on the one hand the needle carrier is positioned in the direction of the longitudinal axis of the receptacle in its operating position and on the other hand after the locking device has been released the cover element is distanced from this in the disposal position by this further adjusting device with simultaneous adjustment of the needle carrier is arranged within the receptacle and thus automatic coverage of a needle end of the needle arrangement is ensured.

The configuration according to claim 4 makes it possible to be able to arrange the needle carrier between the two adjusting devices, it being possible for the needle carrier to be inserted starting from the larger end region towards the smaller end region.

According to another embodiment variant, a simple assembly is created, within which the needle carrier can still be clamped between the windings and on the one hand an exact longitudinal positioning in the direction of the longitudinal axis of the receptacle and on the other hand a compact assembly can be created. Furthermore, the assembly of the needle carrier with the adjusting device can be greatly simplified by the conically widening adjusting devices.

A further development according to claim 6 is also advantageous, since it enables simple operation, in particular one-hand operation, in which no additional movement sequences need to be carried out simply by symmetrically releasing the latching device, and thus the end of the needle arrangement which is predetermined for removal or reception . for example, from the veins or veins of a patient, can be pulled out relative to the patient by the first adjusting device without further changing the location of the receiving container. At the same time, however, the further end of the double-ended cannula is also covered in the region of the distal end, as a result of which access and associated puncture injury from the two ends of the cannula are prevented. A simple one-hand operation has thus been created, in which the two ends of the needle arrangement are additionally arranged within the receptacle and an unintentional puncture injury can also be avoided in the region of the distal end.

In the embodiment according to claim 7, it is advantageous that in this way the insertion of the blood sample tube for the intended removal process and the puncturing process into one end of the cannula is reliably made possible in the smallest longitudinal extent in the direction of the longitudinal axis, and on the other hand it is operationally reliable in the disposal position Covering this cannula end is made possible.

The refinement according to claim 8 ensures that the end of the cannula facing the blood sampling tube can protrude through the cover element in the smallest position in the use position and that this end is nevertheless securely covered by the cover element in the disposal position.

Due to the design according to claim 9, residues on the cannula or the protective sheath surrounding it can be sucked up or ingested during the relative adjustment movement between the cover element and the needle carrier and thus infection or infection by spraying away individual particles, in particular body fluids such as blood or the like, can be prevented.

An embodiment according to claim 10 is also advantageous, since on the one hand a secure mounting of the cover element and the needle carrier connected therewith is ensured within the receptacle and on the other hand a uniform triggering by the diametrically opposite latching elements can take place by the user. This also prevents the components to be adjusted from tilting within the receptacle. According to the designs as described in claims 11 to 13, a simple interaction of the locking elements on the cover element with the locking recesses arranged in the container wall can be achieved, here simple operation by a simple pressure in the direction of the longitudinal axis, that is to say the center of the receiving container , is created for releasing the locking device. Due to the multiple arrangement of the

Locking elements on the cover element can be achieved by loosening the locking device by the additional locking elements, a support or centering of the cover element relative to the receptacle, better centering can be achieved, whereby a more reliable triggering with an associated, immediately subsequent guidance during the entire adjustment movement into the Disposal position is reached.

The embodiment according to claim 14 is advantageous, since it enables simple actuation of the latching device from the outside of the receptacle.

As described in claim 15, on the one hand an unintentional triggering is prevented by the possible protrusion of the latching elements over the outer surface of the container wall and on the other hand the necessary adjustment path for triggering the latching device is defined in a predeterminable way in order to prevent incorrect operation or incorrect triggering.

In this case, an embodiment according to claim 16 proves to be advantageous, since it always ensures a secure locking of the latching device in the operating position and thus a high level of operational reliability of the entire receiving device is achieved.

According to the designs, as described in claims 17 and 18, a distancing of the base body from the inner surface of the receptacle is achieved, whereby the guide arrangement between the cover element and the receptacle is reduced to a partial area, viewed in the radial direction, compared to the overall circumference and so a smooth and tilt-free guide arrangement has been created.

A further development according to claim 19 is also advantageous, since on the one hand for the assembly process and on the other hand over the entire adjustment movement of the cover element between its two end positions, the adjusting device is always held in a predeterminable position on the base body, thereby ensuring a smooth movement.

According to advantageous developments according to claims 20 to 23, a tilt-free longitudinal movement is always ensured during the relative adjustment of the cover element in the direction of the longitudinal axis relative to the receptacle, without the cover element being rotated about the longitudinal axis.

In the embodiment according to claim 24, it is advantageous that the distance between the groove base of the guide groove and the longitudinal axis is constant over the entire adjustment path of the cover element. A secure longitudinal adjustment of the cover element between its two end positions is thereby achieved.

The embodiment according to claim 25 enables proper guidance in the direction of

Longitudinal axis also a directional arrangement and triggering of the locking device.

Another embodiment according to claim 26 is also advantageous, since as a result the cover element is always guided over its entire longitudinal movement in the direction of the longitudinal axis between its two settings, and a high level of operational reliability of the entire receiving device can be achieved.

Furthermore, an embodiment according to claim 27 is advantageous, since this always results in a parallel alignment of the guideways with respect to the longitudinal axis, and so the distance between the longitudinal axis and the guideways is always the same over the entire adjustment path.

Due to the design according to claim 28, it is also possible to achieve a flawless guidance between the use position and the disposal position of the respective parts to be adjusted within the receptacle, thereby ensuring high operational reliability and thus adequate protection for the operating personnel.

Further advantageous embodiments of the guide arrangement are in claims 29 to 31 described. It is advantageous that the contact force directed by the latching elements onto the guideway means that the cover element is always positioned centrally to the longitudinal axis and, due to the predeterminable contact force, the same friction conditions can always be achieved for the entire adjustment path, provided the surface quality remains the same.

Further advantageous embodiments of the further guide arrangement are characterized in claims 32 to 34, a predetermined, linear guide arrangement having also been created for the needle carrier, with which a safe adjustment of the same from the use position to the disposal position is made possible. The multiple arrangement of the guide elements also results in a tilt-free and, above all, non-rotatable longitudinal movement.

In addition to the guide elements in the area of the inner surface of the receptacle, the design according to claim 36 provides an additional, further guide option, as a result of which the needle carrier can be adjusted even more precisely in the direction of the longitudinal axis.

The further developments of the further guide arrangement, according to claims 37 to 40, on the one hand create an exact and above all non-rotatable longitudinal guidance of the needle carrier in the area of the inner surface of the receptacle, and on the other hand ensure a longitudinal movement into the disposal position so that the risk of injury for the operating personnel is high is reduced.

The embodiment according to claim 41 is advantageous, since this allows longitudinal adjustment to take place in the region between the cover element and the inner surface of the receptacle, but an unintentional intervention in the interior of the receptacle sealed off from the cover element is reliably prevented.

According to claim 42, simple insertion of the structural unit formed by the needle carrier and the cover element into the receiving container is made possible, support being provided in the region of the further end for the structural unit supported by springs. In the embodiment according to claim 43, a longitudinal guide for the needle carrier is created in the region of the end wall, in order to be able to absorb transverse loads during the intended use and subsequently to allow a simple sliding movement between these components after the intended use.

According to claim 44, a receiving space for the adjusting device, which is separate from the needle carrier, is created for the adjusting device in order to be able to store a sufficient restoring force exerted by the adjusting device in a very small space and also to prevent jamming between the components during their intended use.

Due to the design according to claim 45, a double-ended removal needle can simply be used in the sleeve-shaped support body, and support can also be provided on the receptacle in the region of the outer surface.

In the embodiment according to claim 46, it is advantageous that the adjustment devices for fixing the position of the entire needle carrier can be supported during its intended use in the use position.

Advantageous designs and arrangements of the adjustment devices on the support element are described in claims 47 to 49, since in this way a simple and, above all, inexpensive to assemble unit is created when the needle carrier is clearly positioned relative to the receptacle.

Further advantageous embodiments of the needle carrier are described in claims 50 to 52, whereby a continuous support for the first adjusting device with simultaneous centering of the same with respect to the needle carrier can be achieved. The tubular recess also creates a predeterminable support position for the further adjusting device, as a result of which the needle carrier is kept positioned between the two adjusting devices and a high level of operational safety can thus be achieved. Furthermore, the centering element can also be used for the oriented alignment of the needle carrier for installation in the receptacle, so that the alignment of the needle arrangement to be used in the thread arrangement in relation to the latching device - left

to be able to fix

As described in claims 53 and 54, a predefined position of the cannula tip, in particular the bevel arranged thereon, for the puncture in relation to the latching device can be created, in order to allow simple one-hand operation without the

To allow danger of a puncture injury caused by the usual adjustment processes.

Due to the design according to claim 55, a simple handling is achieved for the insertion process of the removal needle into the needle carrier, since here the entire receptacle can be kept simple and the removal needle in the needle carrier without another

Fixation can be screwed in easily.

Further advantageous embodiments of the cover element and the receptacle are characterized in claims 56 to 59, wherein this prevents the cover element from being readjusted into the receptacle chamber of the receptacle and thus an unwanted puncture injury with a possible infection can be prevented.

In the embodiment according to claim 60, an undesired emergence of the cover element from the receiving space of the receptacle is prevented, wherein a clear position fixation is created in the direction of the longitudinal axis when interacting with the retaining elements. Furthermore, the spring force of the adjusting devices can thereby be increased, since an undesired emergence is prevented in this way.

However, an embodiment as described in claim 61 is also possible, since this prevents additional protection against rotation of the cover element about the longitudinal axis relative to the receptacle.

Through the developments according to claims 62 and 63, in the area of the distal end, on the one hand, a high degree of installation friendliness is achieved when the securing element has not yet been inserted, and on the other hand, after the securing element has been inserted into the receiving container, a high level of operational safety of the entire receiving device is achieved. An embodiment according to claim 64 is also advantageous, since it enables a precisely fitting insertion of the securing element into the distal end of the receptacle and, at the same time, a clear positional positioning within the receptacle can be achieved in cooperation with the flange-shaped attachment.

Further developments according to claims 65 to 68 are also advantageous, since on the one hand the insertion of the securing element is made easy by the projecting positioning elements and on the other hand a stop limitation for the adjustment path of the needle carrier and thus a safe positioning of the same within the receptacle in the disposal position is created , A higher spring force can thus be applied to the needle carrier by the adjusting device, with which the latter is then securely pressed onto the positioning elements.

Furthermore, configurations as described in claims 69 and 70 are also possible, since in this way the cover element is held on the securing element in both directions in the direction of the longitudinal axis in the disposal position of the receiving device. As a result, a higher spring force can be applied to the cover element by the further adjusting device, in order to achieve a safe adjustment thereof in the disposal position. This is particularly important for the latching elements arranged on the holding arm, since they have to be adjusted over the retaining elements to reach the disposal position in order to reach the disposal position.

Finally, a further development, as characterized in claim 71, is advantageous, since this also prevents pivoting or twisting about the longitudinal axis in the disposal position and thus prevents subsequent manipulation. On the one hand, injury to the operating personnel and, on the other hand, reuse of the entire receiving device with the already unlocked latching device can be prevented.

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 position information selected in the description, such as, for example, top, bottom, side, etc., are based on the figure described and illustrated immediately and are to be transferred accordingly to the new position in the event of a change in 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 6, a receptacle 1 for a receptacle, not shown here, such as a well-known blood sample tube, is shown in simplified form, and this an outer receptacle 2, a cover element 3 inserted therein and a needle carrier 4 with a mostly double-ended cannula 5 includes.

The receptacle 2 has an elongated spatial shape and delimits a receptacle chamber 7 with a receptacle wall 6. In the direction of a longitudinal axis 8, the receptacle 1 or the receptacle 2 has a proximal end 9 and a distal end 10 spaced apart from one another. The container wall 6 is delimited by an inner surface 11 facing the receiving chamber 7 and an outer surface 12 facing away from it. In the embodiment shown here, one of the two ends - in the present embodiment the distal end 10 is open and the other end - here the proximal end 9 - is at least partially closed. The proximal end 9, which is partially closed here, is partially closed by an end wall 13.

In general, it should also be pointed out here that the designation of the two ends 9, 10 was chosen based on the patient. Thus, the proximal end 9 faces the patient and the distal end 10 faces away from the patient.

In the position of use of the needle carrier 4 shown in FIG. 1 and a needle arrangement 14 that can be held thereon or therein, which in the present exemplary embodiment is formed by the double-ended cannula 5, one end protrudes, which is designed to be inserted into a living being or a removal vessel , over the end wall 13 in the direction facing away from the receiving chamber 7. The further end of the cannula 5 protrudes over a partial area into the receiving chamber 7 of the receiving container 2, as a result of which, in a known manner, a receptacle, not shown here, in particular a blood sampling tube, is inserted into the receiving chamber 7 and the sealing device of the blood sampling tube is pierced by this end of the cannula 5 is and so a connection can be made via the cannula 5 with the interior of the blood sampling tube. Furthermore, the needle carrier 4 in the receiving chamber 7 of the receiving container 2 is designed to be displaceable relative to the latter, if necessary, from the use position shown in FIG. 1 in the area of the proximal end 9 in the direction of the distal end 10 into a disposal position according to FIG. 2. For this purpose, a first adjustment device 15 is assigned to the needle carrier 4 for this shift, if necessary, from the use position into the disposal position. The cover element 3 is arranged in FIG. 1 - the use position of the needle arrangement 14 - directly adjacent to the needle carrier 4 on the side facing away from the proximal end 9 in the receiving chamber 7. Between the cover element 3 and the receptacle 2 of the receptacle 1 it is further shown in FIG. 1 that a detachable locking device 16 is arranged here, with which the cover element 3 is held relative to the receptacle in the position of use. Furthermore, a further adjustment device 17 is arranged between the needle carrier 4 and the cover element 3, the cover element 3 being released by this further adjustment device 17 when the latching device 16 is released

Direction of the distal end 10 of the receptacle 2 is adjusted.

The needle carrier 4 is thus assigned on the one hand on the side facing the end wall 13 the first adjusting device 15 and on the other hand on the side facing the cover element 3 the further adjusting device 17 and by these two adjusting devices 15,

17 positioned in its position in the use position in the direction of the longitudinal axis 8. The further adjusting device 17, as already described above, is arranged between the needle carrier 4 and the cover element 3, the cover element 3 being releasably held in its position, if necessary, relative to the receptacle 2 in its position by the latching device 16.

The first adjusting device 15 and / or the further adjusting device 17 are advantageously each formed by an elastically deformable spring element 18, 19, in particular a compression spring. These compression springs can be formed from a wide variety of materials and with a wide variety of deformation and spring properties, and spiral springs can preferably be used. Furthermore, it is advantageous if the further adjusting device 17, starting from the needle carrier 4 to the cover element 3, is designed to expand conically, as is shown in simplified form in FIG. 2. Irrespective of this, it is also possible to form the first and the further adjusting device 15, 17 by means of a one-piece component, since the assembly effort and the number of

Items can be reduced.

Due to the arrangement of the two adjustment devices 15, 17, both the needle is ger 4 and the cover 3 at the same time from the use position to the disposal position after releasing the locking device 16.

In this exemplary embodiment, the cover element 3 is formed by a base body 21 which is approximately disc-shaped in a plane 20 oriented perpendicular to the longitudinal axis 8.

As already described above, the end of the cannula 5 facing the blood sampling tube and thus the receiving chamber 7 projects through the cover element 3 in the region of the longitudinal axis 8 in an opening 22. Furthermore, FIG. 2 shows in a simplified manner that in the region of the opening 22 there is a a liquid absorbing or absorbing component 23 can be arranged, which can be penetrated by the cannula 5 or the protective sheath 24 shown above and simplified. This component 23 serves to remove possible residues in the area of the cannula 5 or on the protective sheath 24, in particular blood drops, during the relative adjustment movement between the

Needle carrier 4 and the cover element 3, due to the adjusting device 17, to be able to pick up or absorb, in order to avoid splashing away and thus a possible infection of the operator.

The locking device 16 has at least one, but preferably two diametrically opposite locking elements 25 and locking recesses 26 cooperating therewith. In this exemplary embodiment, this or the latching elements 25 are arranged on the disk-shaped basic body 21 of the cover element 3, the latching recesses 26 being arranged in the container wall 6 of the receiving container 2 and enforcing them for the release of the latching elements 25 from outside the receiving container 2. In order to avoid unintentional detachment of the latching elements 25 from the latching recesses 26, it is advantageous if the latching element (s) 25 protrude only partially into the latching recesses 26 in the radial direction, starting from the inner surface 11 towards the outer surface 12 of the container wall 6. As a result, the trigger path is reduced in the radial direction toward the longitudinal axis 8 and at the same time the risk of incorrect operation or unintentional triggering is reduced. The one or more locking elements 25 are resilient, for example via a web connected to the disc-shaped basic body 21 of the cover element 3. The locking elements 25 protrude by means of the resilient web Direction of the needle carrier 4 from the disc-shaped basic body 21 in front.

Furthermore, at least one guide arrangement 27 can be provided between the cover element 3 and the inner surface 11 of the container wall 6, by means of which the cover element 3 is adjusted in an exclusive longitudinal movement in the direction of the longitudinal axis 8 from the use position to the disposal position in the region of the distal end can, without being able to rotate about the longitudinal axis 8. This guide arrangement 27 is formed by at least one guide groove 28, which is recessed in the container wall 6 and runs in the direction of the longitudinal axis 8, and at least one guide extension 29 on the cover element 3 which engages in the guide groove 28. To achieve a tilt-free

Longitudinal adjustment in the direction of the longitudinal axis 8, it is advantageous if a plurality of guide grooves 28 are arranged uniformly distributed over the circumference of the receptacle 2, in which a plurality of guide extensions 29 of the cover element 3 also engage. In a diametrically opposed arrangement of the latching devices 16, these are arranged symmetrically between the guide grooves 28, seen in the direction of the longitudinal axis 8, over the circumference of the receiving container 2, since on the one hand a perfect release and on the other hand an unimpeded longitudinal adjustment of the cover element 3 in the direction of the longitudinal axis 8 within the Receiving container 2 can be done. Furthermore, it is advantageous if a groove base of the guide groove 28 runs parallel to the longitudinal axis 8 over its longitudinal extent relative to the latter.

The container wall 6 has a circular cross-section in the plane 20 aligned perpendicular to the longitudinal axis 8, an outer diameter 30 of the disk-shaped basic body 21 roughly corresponding to an inner diameter 31 of the receiving chamber 7 in the same plane or being selected only slightly smaller , This ensures that, on the one hand, an unimpeded longitudinal adjustment of the cover element 3 in the direction of the longitudinal axis 8 can take place within the receiving chamber 7 and, on the other hand, the receiving chamber 7 is also covered by the cover element 3 over a large part of the cross-sectional area.

The receptacle 2 is open in the area of the distal end and partially closed with the end wall 13 in the area of the proximal end 9. As a result, in the area of the proximal end 9, support is provided which is supported by the adjusting device 15. practiced pressure forces on the end wall 13 possible. Furthermore, an opening 32 is arranged in the end wall 13 in the region of the longitudinal axis 8, the cross-sectional dimension 33 of which corresponds approximately to an outer cross-sectional dimension 34 of the needle carrier 4. Thus, as can best be seen from FIG. 1, a portion of the needle carrier 4 can protrude into the opening 32, as a result of which the needle arrangement 14, in particular the cannula, is inserted

5, can be facilitated in the needle carrier 4.

Furthermore, a receiving space 35 for the first adjusting device 15 or the one-piece component formed by the adjusting devices 15, 17 is arranged in the end wall 13. As a result, both the needle carrier in its bearing, guided in the direction of the longitudinal axis 8 and the adjustment device 15 or the component formed by it, can be stored and held separately in the smallest space.

The needle carrier 4 is formed by an approximately sleeve-shaped support body 36, with at least one support element 37 projecting radially outward from it being arranged in the plane 20 oriented perpendicular to the longitudinal axis 8. This support element 37 is preferably designed to run continuously over the circumference and is used for the fact that the adjusting devices 15, 17 are supported thereon at the end regions facing each other. However, it is also possible to arrange a plurality of support element 37 distributed over the circumference on the supporting body 36. To better fix the position of the needle carrier 4 relative to the adjustment devices 15, 17, it is advantageous if at least one of the end regions is fixed on the support element 37. This in turn can reduce the assembly effort for final assembly. When the adjusting device 15, 17 is formed in one piece, the support element 37 is arranged in a transition region thereof and is held on this one-piece component. If, as already described above, the further adjustment device 17 or the part of the one-piece component forming it is conical in the direction of the distal end 10, it is possible to insert the needle carrier 4 with the support element arranged thereon up to the transition region, in which case the support element 37 can accordingly be inserted and held between the turns of the adjusting device.

Furthermore, it can be seen from FIG. 3 that in the area of the opening 32 in the end wall 13, between the latter and the part of the needle carrier 4 protruding into the opening 32 (see FIG. 1), an anti-rotation device 38 is arranged, which in the operating position the needle carrier gers 4 is engaged and prevents relative pivoting or rotation between the receiving container 2 and the needle carrier 4 about the longitudinal axis 8. In the present exemplary embodiment, this anti-rotation device 38 is formed by flats arranged on the supporting body 36 and in the region of the opening 32 with corresponding, oppositely designed stop surfaces. This results in a longitudinal movement of the needle carrier 4 in

Direction of the longitudinal axis 8 is possible, but prevents rotation about the longitudinal axis 8 in the use position.

1, 2 and 4, it can also be seen that when the needle carrier 4 is in the disposal position, the cover element 3 in the region of the distal end — as shown in FIG. 2 — by the interaction of the adjustment devices 15 , 17 and is held there relative to the receptacle 2 in its longitudinal movement in the direction of the longitudinal axis 8 by means of a locking device 39. In this exemplary embodiment, the locking device 39 is by at least one arranged on the receiving container 2 and facing the distal end 10

Retaining element 40 and at least one locking element 41 cooperating therewith are formed on the cover element 3. The one or more retaining elements 40 can each be formed by a resilient part of the container wall 6, which is designed to protrude at least over a partial area of its longitudinal extent in the direction of the longitudinal axis 8 over the inner surface 11 in the direction of the longitudinal axis 8. Due to the resilient design of this retaining element 40, a movement of the cover element 3 from the proximal end 9 in the direction of the distal end 10 is possible, the retaining elements 40 being adjusted radially outwards against their spring action on the side facing away from the longitudinal axis 8, and thus the Passage of the cover element 3 up to the springing back of the retaining elements 40 is made possible.

If the retaining elements 40 are in turn moved back into their original position or are sprung open, a movement of the cover element 3 in the direction of the proximal end 9 is prevented. This prevents accidental reaching into the receiving chamber 7 of the receiving container 2 and the needle arrangement 14 located therein.

In order to prevent the cover element 3 from escaping from the receiving chamber 7 of the receiving container 2 during the adjustment movement into the disposal position, the locking device 39 additionally has at least one arranged on the receiving container 2 and the distal end 10 facing stop element 42 for the cover element 3. Thus, the cover element 3 is seen in the direction of the longitudinal axis 8 on both sides in its ability to move and thus fixed in the disposal position.

The retaining element or elements 40 are arranged in the region of the guide arrangement 27, in particular in the guide groove 28, in the end region thereof facing the distal end 10. Likewise, the stop element or elements 42 are also arranged in the region of the guide arrangement 27, in particular in the guide groove 28.

As is generally known, a thread arrangement 43 for the needle arrangement 14 is arranged in the sleeve-shaped support body 36 of the needle carrier 4, but this thread arrangement 43 is oriented in such a way that when the releasable latching device 16 for the cover element 3 is arranged opposite one another and horizontally oriented, one on a cannula tip 44 is arranged Bevel 45 is arranged running on an upper side of the cannula 5, as can best be seen from FIG. 1. Thus, the entire receiving device 1 can be held with the thumb and forefinger, for example during right-handed operation, and already held in the area of the latching device 16 for the removal process or intended use, at the same time the cannula 5 then in the correct position for the removal process, namely with the bevel is arranged on the side of the cannula 5 facing the user and visible. This always ensures a directed position after the insertion process of the needle arrangement 14 in the needle carrier 4 relative to the entire receiving device 1. A twisting or adjusting or additional handling of the cannula and the associated stab injury is therefore very highly excluded or even prevented.

7 to 17 a further embodiment of the receiving device 1 for a receiving vessel, also not shown here, such as, for example, a generally known blood sample tube, is shown in simplified form. Likewise, the same reference numerals or component names are used for the same parts. To avoid unnecessary repetitions, reference is made to the detailed description in the preceding

Fig. 1 to 6 pointed out or referred. 18 basically shows the components shown in FIGS. 7 to 17, but with a modification of the anti-rotation device 38 between the needle carrier 4 and the receptacle 2. In this exemplary embodiment, the receiving device 1 in turn comprises the receiving container 2, the cover element 3, the needle carrier 4 with the needle arrangement 14 inserted or insertable therein, in the first instance the double-ended cannula 5. In addition, the receiving device 1 also includes in the region of the distal end 10 of the receiving container - At least 2, at least one security element 46 inserted in this, which is shown schematically in FIGS. 15 and 16 schematically in perspective representations.

FIG. 7 again shows, as has already been shown in FIG. 1, the use position in which the needle carrier 4 with the cannula 5 inserted or insertable therein and the cover element 3 are arranged in the region of the proximal end 9 of the receiving container 2 are and the two adjusting devices 15, 17 are in a prestressed position, from which they release or adjust the needle carrier 4 and the cover element 3 into the disposal position by the spring force acting on these parts after unlocking the latching device 16. This adjustment process has already been described in detail in the previous FIGS. 1 to 6 and will not be discussed further here.

The securing element 46 is inserted into the receiving chamber 7 of the receiving container 2 and can be locked or held thereon. This creates the possibility of inserting the needle carrier 4, the cover element 3, optionally the cannula 5, and the adjusting devices 15, 17 or also a single component formed from these two into the receiving chamber 7 of the receiving container 2 and the latching device 16 in the region to position the proximal end 9 in its locked position and only then to insert the securing element 46. This makes assembly easier since, over the entire insertion process of the previously described individual parts in the area of the proximal end 9, the receptacle 2 has no retaining elements or stop elements in the area of its distal end 10, and the insertion process can thus be carried out simply and almost unhindered.

As can now be seen from the simplified illustration of the receiving device 1 from FIGS. 7 and 8, the first adjusting device 15 is arranged between the end wall 13 and the needle carrier 4. In order to center or stabilize this adjusting device 15, a groove-promoting section is provided in the area of the end wall 10 on the side facing the receiving comb. arranged or formed recess 47, in which one end of the adjusting device 15 is inserted. The further end of the adjusting device 15 which is turned away from it is supported on at least one support element 37 which projects radially outward beyond the sleeve-shaped support body 36. In this exemplary embodiment, the support element 37 is designed as a support part 48 which extends over the circumference and projects beyond the support body 36.

In addition, it is also possible for at least one first centering element 49 for the first adjustment device 15 to be arranged on the region of the support part 48 or the support element 37 facing the proximal end 9. The interaction of the support body 36 with the centering element (s) 49 in turn results in the first adjustment device 15 being positioned relative to the needle carrier 4.

In addition, the centering element 49 can also be used for pre-orientation and subsequently for the correct insertion of the needle carrier 4 into the receiving chamber 7. Since the thread arrangement 43, as has already been described in FIGS. 1 to 6 and will be briefly explained again below, is a clearly predetermined one

Position or position in relation to the receptacle 2 and the locking device 16 arranged between the latter and the cover element 3 for the alignment of the cannula tip, this predetermined insertion position is important for this process. With one-handed operation of the receiving device 1, the end of the cannula 5, which is in use during the intended use, can be pulled out of the patient by the adjusting forces applied by the adjusting devices 15, 17 by simply triggering the latching device 16, without having to change the grip and thus one Change in position of the entire receiving device 1 with respect to the patient must take place. The cannula end can be pulled out of the patient with one-handed operation, for example by the interaction of the thumb and forefinger, and the puncture opening can be covered with a swab with the other free hand. This creates a high level of safety for the operating personnel and greatly reduces or even avoids the risk of injury from unintentional stinging and an associated infection.

Furthermore, in the center of the sleeve-shaped support body 36, the thread arrangement 43 for the needle arrangement 14 is provided, which is aligned in its alignment with the threads of the needle arrangement 14 in such a way that, when the position is completely screwed in, a short zere opening axis of the opening on the beveled cannula tip in the region of the proximal end 9 is aligned approximately parallel to the two opposite recesses 26. The thread arrangement 43 for the needle arrangement 14 can be formed by a two-start thread, the thread segments being aligned in such a way that when the arrangement is opposite and the orientation is horizontal, the releasable ones

Latching device 16 for the cover element 3, a bevel 45 arranged on a cannula tip 44 is arranged running on an upper side of the cannula 5, as has already been explained or shown in the description and the illustration of FIG. 1. Independently of this, however, any other coupling device between the needle arrangement 14 and the needle carrier 4 can of course also be selected. Likewise, the needle arrangement 14 can also comprise only one cannula 5 with a correspondingly designed holding part, the cannula 5 exclusively facing the proximal end 9 and not projecting into the receiving chamber 7. A syringe needle could also be used.

Furthermore, it can be seen from FIG. 8 that the latching device 16 in the region of the receptacle 2 has at least one projection which is assigned to the latching elements 25 and projects beyond the inner surface 11 in the direction of the longitudinal axis 8, this projection being the end of the latching recess 26 represents. In the present case, this latching recess 26 is only recessed in the container wall 6 and is closed in the region of the outer surface 12. In this area, the container wall has only a very small wall thickness, which enables the latching device 16 to be actuated. The covered design of the locking recess 26 provides additional protection against the escape of liquids from the receiving chamber 7 to the outside. Otherwise, this would be easier by adjusting the tip of the cannula into the receiving chamber 7.

The further adjusting device 17, between the needle carrier 4 and the cover element 3, is supported on the one hand in the area of the needle carrier 4 on the area of the supporting body 36 or possibly the support element 37 facing the distal end 10 and on the other hand on the base body 21 of the cover element 3. The distal end is preferred

10 facing area of the needle carrier 4, in particular the Tragköφers 36, in this a further tubular recess 50 is formed, in which one end of the further adjusting device 17 can be inserted. This in turn ensures good centering same reached.

A further centering element 51 for the further adjusting device 17 can also be arranged on the cover element 3 in the area of the base body 21 facing the proximal end. This centering element 51 is here in the form of a tubular extension

Grundköφer 21 formed, and can serve as an inner or outer centering for the spring element preferably formed by a compression spring made of a metallic or a plastic material.

7 to 9 and 17 and 18, it can be seen that between the receiving container 2, in particular its container wall 6, and the cover element 3, in turn, at least the first guide arrangement 27 and between the needle carrier 4 and the receiving container 2 a further guide arrangement 52 is provided. To form at least part of one of the guide arrangements 27, 52, a partial region 53, 54 of the inner surface 11 of the container wall 6 is in each case designed as a guide track 55, 56. The guideways 55, 56 or the subregions 53, 54 are preferably aligned parallel to the longitudinal axis 8 thereof along their longitudinal extent. The partial areas 53, 54 of the inner surface 11 or the entire inner surface 11 is particularly preferably cylindrical in relation to the longitudinal axis 8 - that is to say always at the same distance from the longitudinal axis 8. However, it would also be possible to design the entire inner surface 11 or even only at least one of the partial areas 53, 54 with a production-related draft. This can, for example, up to max. Amount to 0.5 ° and depends on the selected manufacturing process and the materials used.

As already described previously in FIGS. 1 to 6, the first guide arrangement 27 is formed between the cover element 3 and the receptacle 2. The latching device 16 in turn comprises at least one latching element 25 and at least one latching recess 26 cooperating therewith in the receiving container 2. The latching recess 26 can either be arranged in the container wall 6 or else in the region of the end wall 13. In this embodiment shown here are on the Grundköφer 21 of the cover

3 a plurality of, preferably four, locking elements 25 arranged uniformly distributed over the circumference, with several, preferably two diametrically opposed and together with two of the locking elements 25 to form the locking device 16 in the receiving container 2. acting recesses 26 are arranged or recessed.

Furthermore, it is possible for the latching element (s) 25 to be arranged on a holding arm 57 protruding from the base body 21 of the cover element 3 in the direction of the needle carrier 4 or the proximal end 9, as best shown in FIGS 11 and 12 can be seen. In this case, the latching elements 25 and, if appropriate, the holding arm or arms 57 are arranged in the region of the outer circumference of the cover element 3. The first guide arrangement 27 extends at least over an entire adjustment path 58 of the cover element 3 between the use position or its standby position in the area of the proximal end 9 and the disposal position or its cover position in the area of the distal end 10. This ensures that Cover element 3 is always guided in the direction of the longitudinal axis 8 during its entire adjustment movement. The first guide arrangement 27 is formed here by the abutment or interaction of the latching elements 25 arranged on the holding arm 57 on the one or more guideways 55. It is advantageous if the latching element (s) 25, optionally with the interposition of the holding arm 57, bear with a predeterminable or predetermined radially directed bearing force in the direction of the guideway 55. If, as already described above, the partial region 53 of the guideway 55 is aligned parallel to the longitudinal axis 8, an almost equally high contact force is achieved over the entire adjustment path 58 of the cover element 3.

The further guide arrangement 52 between the receptacle 2 and the needle carrier 4 comprises in the region of the receptacle 2 at least one guide element 59 which is arranged on the inner surface 11 thereof and projects in the direction of the longitudinal axis 8 and projects beyond the inner surface 11, e.g. a web, a rib or the like. Zur

To achieve a linear adjustment, this is or the guide elements 59 are aligned in the direction of the longitudinal axis 8. Two guide elements 59, which are arranged next to one another over the circumference, preferably form part of the further guide arrangement 52 between the receptacle 2 and the needle carrier 4. To achieve a more uniform and tilt-free guide, a plurality of guide elements 59 are preferably evenly distributed in pairs over the circumference, in particular arranged in a cross shape to each other. As already described above, the further guide arrangement 52 comprises at least one further guideway 56, which is between the two side by side guide elements 59 is arranged to extend.

As can best be seen now from FIGS. 7, 8 and 13 and 14, the further guide arrangement 52 in the area of the needle carrier 4 comprises at least one guide extension 60 which interacts with the guide element (s) 59. The guide extension 60 is in this case is approximately web-shaped and extends approximately parallel to the longitudinal axis 8. In this exemplary embodiment shown here, the or the guide extensions 60 are connected to the support element 37 or support part 48 via the interposition of a support arm 61 shown in simplified form and subsequently to the support body 36. The entire needle carrier 4 is preferably produced from a one-piece component, in particular by injection molding.

In the assembled state, the guide extensions 60 are arranged in the area of the receptacle 2 in each case between the two guide elements 59 arranged next to one another and seen on the one hand in the radial direction through the partial area 54 forming the guide track 56 and in the direction of the longitudinal axis 8 by at least one , but preferably between the two guide elements 59. The guide extensions 60 and optionally the support arms 61 are preferably evenly distributed over the circumference, in particular mutually arranged, on the support element 37 or support part 48 in accordance with the circumferential arrangement of the guide elements 59.

If the number of guide tracks 55, 56 arranged on the inner surface is uniform, they are each cruciform with respect to one another - that is to say they are each distributed over the circumference by 90 °. Furthermore, the guideways 55 are in turn offset with respect to the guideways 56 by a uniform amount over the circumference, an angle of 90 ° also being found here as preferred.

The previously described first guide arrangement 27, between the cover element 3 and the receiving container 2, is formed at least by the latching elements 25 brought into abutment on the inner surface 11. To ensure that the cover element 3 is secured against rotation about the longitudinal axis 8, it is advantageous if at least one of the guide elements 59 projects into or engages with at least one partial cutout 62 formed in the peripheral region of the cover element 3, this partial cutout 62 in FIG Seen peripheral area, is arranged in the Grundköφer 21 between the locking elements 25 or holding arms 57. This can best be seen from the simplified illustration in FIG. 17.

As described in the introduction to these figures, is additionally in this embodiment

Area of the distal end 10 of the receptacle 2 is arranged on this at least one securing element 46, which can best be seen from an overview of FIGS. 15, 16 and 18. This securing element 46 is designed for subsequent insertion into the receiving chamber 7 and held there in a latched manner on the receiving container 2. In the exemplary embodiment shown here, the securing element 46 comprises a sleeve-shaped support part 63 and a flange-shaped extension 64 connected to it, which projects beyond the support part 63 in the direction facing away from the longitudinal axis 8. For better positioning, it can be advantageous if the flange-shaped extension 64 has diametrically opposite flats 65 and these can be used in cooperation with the extension 64 in a recess in the receptacle 2 arranged in the region of the distal end 10.

At least one positioning element 66 aligned in the direction parallel to the longitudinal axis 8 can be arranged on the sleeve-shaped support part 63, which extends beyond the support part 63 in the direction of the proximal end 9 of the receptacle 2. Advantageously, several, preferably four, positioning elements 66 are provided, distributed uniformly over the circumference, in particular arranged in a cross shape with respect to one another. This division corresponds in terms of angle to the arrangement of the partial areas 54 on the inner surface 11 of the receptacle 2, as can best be seen from FIG. 9. During assembly, the positioning elements 66 protrude in the direction of the proximal end 9 and are additionally arranged between the guide elements 59 which are arranged next to one another in pairs. These positioning elements 66 thus protrude into the partial area 54 or guide tracks 56 for the guide extensions 60 arranged on the needle carrier 4 and limit an adjustment path 67 of the needle carrier 4, starting from the proximal end 9 in the direction of the distal end 10. It is therefore possible that to provide the adjusting device 15 with a correspondingly high pretensioning force in order to ensure a secure adjustment of the needle carrier 4 and thus the needle arrangement 14 into the disposal position and the needle carrier 4 by the stop of the guide extensions 60 on the proximal end 9 pressed ends of the positioning elements 66.

To limit the adjustment path 58 of the cover element 3 and thus prevent it from escaping from the receiving chamber 7 of the receptacle 2, in this exemplary embodiment instead of the stop element 42 described in FIGS. 1 to 6, which was arranged directly on the receptacle 2, here at least one securing element 46; however, preferably a plurality of stop elements 68 arranged distributed over the circumference are arranged. In this exemplary embodiment, these stop elements 68 protrude from the flange-shaped extension 64 in the direction of the longitudinal axis 8 and are thus in cooperation with the locking element or elements 41 on the cover element 3, its longitudinal movement, starting from the proximal end 9 in the direction of the distal end 10, fixed.

In order to prevent the cover element 3 from being pushed in unintentionally, starting from the distal end 10 in the direction of the proximal end 9 in the disposal position, at least one, but preferably in turn a plurality of retainer elements 69 can be arranged on the securing element 46, which in turn has at least one , but preferably a plurality of further locking elements cooperating therewith on the cover element 3, in particular the one or more locking elements 25 arranged on the holding arm 57 form or form part of the locking device 39. In the installed position of the securing element 46 in the receiving container 2, the retaining elements 69 are closer to the proximal end 9 and, in order to facilitate sliding into one another or mutual locking, with the locking elements 25 assigned to them, have a beveled contact surface 70, which starting from the outer edge of the support part 63, which is closer to the proximal end 9 and the inner surface 11 of the receiving container 2, is tapered in the direction of the longitudinal axis 8 and the distal end 9. For mutual locking with the locking element 25, a locking lug 71 cooperating therewith is arranged on the retaining element 69, which protrudes beyond the tubular support part 63 in the direction of the longitudinal axis 8 and forms the locking lug 71 with the contact surface 70.

The latching elements 25, preferably two diametrically opposed ones, on the one hand form the latching device 16 with the latching recess 26 in the position of use in the area of the proximal end 9 and in cooperation with the retention devices in the area of the distal end 10 elements 69 a part of the locking device 39. In the area of the locking device 39, the locking elements 25, which here are distributed uniformly over the circumference, interact with the retaining elements 69 in order to better fix the position of the cover element 3. In the present exemplary embodiment, four latching elements 25 and retaining elements 69, which are evenly distributed over the circumference, are provided.

Of course, it is also possible to provide any number of locking elements 25, locking recesses 26, retaining elements 69, stop elements 68 and locking elements 41. This depends on the size, design and the intended use of the receiving device 1 and can be freely selected according to the requirements placed on the receiving device 1.

Likewise, however, it is also possible, as has already been described in FIGS. 1 to 6, for the cover element 3 to have the opening 22 in the region of the longitudinal axis 8 for the passage of a part of the cannula 5, additionally in the region of the

Breakthrough 22, a liquid absorbing or receiving component 23 can be arranged.

The same also applies to the anti-rotation device 38 arranged between the needle carrier 4 and the receiving container 2. This serves, when the needle carrier 4 is in the operating position, to ensure that relative pivoting or twisting when the needle arrangement 14 is inserted about the longitudinal axis 8 between the needle carrier 4 and the receptacle 2 is prevented secured. In the embodiments described in FIGS. 7 to 17, as can best be seen from an overview of FIGS. 9 and 13, part of the anti-rotation device 38 in the region of the end wall 13 of the receptacle 2 is formed by a groove or web shape Indentations and in the area of the needle carrier 4 formed by the protruding 36 protruding locking projections. In this case, when the needle carrier 4 is in the inserted position, the locking projections engage with the groove-shaped or web-shaped recesses.

However, the anti-rotation device 38 can of course also be formed by any other arrangement or design of components which are in engagement with one another in the operating position, as has already been described and shown in FIGS. 1 to 6 is. In the illustration in FIG. 18, the needle carrier 4 has flats lying opposite one another, which can cooperate with corresponding mating surfaces which are designed in the opposite direction.

As can be seen from a summary of FIGS. 9, 12, 15, 16 and 18, the cover element 3 interacts during its longitudinal movement from the inserted position to the disposal position in the area of the receptacle 2 through the partial cutout 62 arranged on the peripheral area secured against rotation about the longitudinal axis 8 with the guide elements 59. In the area of the securing element 46, in particular in the area of its supporting part 63, no such guide elements 59 are provided in the area of the inner surface 11 of the receptacle 2, which means that the cover element 3 can now be rotated by a certain angular amount about the longitudinal axis 8, which means that or the latching elements 25 can be brought out of engagement with the retaining elements 69 by pivoting or twisting and so the cover element 3 can be adjusted or pressed again in the direction of the proximal end 9 into the receiving chamber 7. This would result in a stab injury through the end of the cannula 5 arranged in the receiving chamber 7.

To prevent this possibly unwanted relative rotation of the cover element 3 with respect to the receptacle 2, in this exemplary embodiment one, but preferably a plurality of rotation locks 72 is provided between the latter or between the securing element 46 and the cover element 3. In the area of the cover element 3, the anti-rotation device 72 is formed by the or the partial cutouts 62 in the peripheral area of the cover element 3. In the area of the receptacle 2 or the securing element 46, the anti-rotation device 72 is arranged, for example, by means distributed over the circumference

Webs 73 are formed which, viewed in the direction of the longitudinal axis 8, are arranged in an extension of the guide elements 59 on the inside of the suspension cable 63. As a result, the cover element 3 is also clearly fixed and held in position in relation to the receiving container 2 or the securing element 46 arranged therein, both in the direction of the longitudinal axis 8 and about the longitudinal axis 8. An unintentional twisting and associated injury and, subsequently, an infection is almost impossible. For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the receiving device, these or their components have been partially shown to scale and / or enlarged and / or reduced.

The object on which the independent inventive solutions are based can be found in the description.

Above all, the individual in FIGS. 1 to 6; 7 to 17; 18 shown embodiments form the subject of independent, inventive solutions. The relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
