Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the passage cross section between the holding element and the release element is reduced, which leads to an increase in the adjusting force.
  • 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.
