Another blood sampling device has become known from EP 0 562 363 A1, which comprises a receptacle with a holder for a blood sample tube, an adapter part inserted in the holder and a double-ended sample withdrawal needle.

One end of the sampling needle protrudes into the interior of the holder and when inserting the blood sample tube, this can be pierced by the end of the sampling needle. To remove a blood sample, the blood sample tube is intended for insertion into the receiving device, during insertion of which an elastic sheath covering the end of the withdrawal needle is compressed in the axial direction until the end of the needle pierces both the sheath and the stopper of the blood sample tube , An adapter part is disposed between the holder and the evacuated blood sample tube. This adapter part has a cylindrical body with an outer dimension that is smaller than an inner dimension of the receiving device. At this cylindrical body a plurality of flexible extensions is formed, which are connected at one end to the cylindrically shaped body and projecting therefrom. These extensions extend axially of the cylindrical body so that they surround the plug of the inserted blood sample tube. The individual extensions are directed forwardly and have an inclined portion which is inclined from the uppermost end of the cylindrical body, starting from the axial center of the cylindrical body in the direction of the upper end of the holder. Following the flexible extensions, a front gripping portion is still provided, which extends parallel to the axial center of the cylindrical body from the oblique portion. Furthermore, additional retaining elements may be provided in the transition region between the flexible extensions and the front gripping portion. However, sufficient retention of the blood sample tube could not be achieved in all applications.

Another connector for a vessel for the introduction or withdrawal of a vaccine culture has become known from EP 0 587 347 B1, DE 693 06 070 T2, US 5,344,417 A and US 5,374,264 A. This connector has a main portion with a means for receiving a needle and an annular edge. This edge extends from the main portion and serves for positioning over the liquid inlet portion of the vessel. On the annular edge further a plurality of ribs on an inner surface thereof is arranged, which radially

protrude inwards. These ribs are capable of engaging the inlet portion of the vessel to substantially center and securely hold the fitting on the vessel during insertion or withdrawal of the seed culture. It could not be achieved in all applications, a secure hold of the fitting on the intended for removal or introduction vessel.

Further adapter pieces with retention extensions have become known from EP 0 192 661 B, US Pat. No. 4,607,671 A, EP 0 363 770 A1 and EP 0 351 643 A2. The disadvantage of this is that when placing or removing the adapter piece from the respective vessel, the entire outer circumference of the adapter piece must be correspondingly deformed in all these adapter pieces, the holder was achieved by a circumferential, annular collar or individual on the inner surface protruding nubs.

The present invention has for its object to provide a receiving device for receiving a medical device having a Haltevonichtung which is inexpensive to manufacture and easy to use and safe to use.

The object of the invention is achieved in that the Haltevonichtung comprises at least one inner surface of the container shell übenagendes in the direction of the longitudinal axis holding member and the retaining element is designed such that this protruding from a clear cross-section of the Aufhahmekammer and thereby with the medical Device engaging detent position is formed in a releasing the medical device release position by an aligned in the direction of the longitudinal axis relative adjustment between the medical device to be used and the container shell is automatically adjustable. The resulting by the features of the characterizing part of claim 1 surprising advantage is that at least one holding element of the Haltevonichtung in its rest position protrudes into the clear cross section of the Aufhahmekammer and upon insertion of the medical device in the Aufhahmekammer without additional operation from the outside an automatic adjustment of the holding element is performed. Thus, on the one hand, the insertion or insertion of the medical device into the receptacle is prevented. N2006 / 14100 14/07 '06 PR 14:37 [SE / EMN 7058] 1 14-7-06; 14: 35

And, on the other hand, after reaching the predeterminable position, the medical device is made possible secured accordingly against falling out. Thus, an unintentional pushing out of the medical device from the Aufnahmekam-mer is avoided by the deformed, hull-shaped shell, thus ensuring a safe removal process. After acceptance or filling of the blood sample tube, this can be easily pulled out of the Aufnahmekam-mer without any further additional operation. A further advantage is that a one-piece receiving device has thus been created, which can be produced cost-effectively without additional assembly costs, save for the possible insertion of the removal needle in an injection molding process.

Also advantageous is an embodiment according to claim 25 or 26, as this despite the release of the holding element or support arm with unhindered freedom of movement, the container wall can be almost completely formed.

According to an embodiment as described in claim 27, a simple shaping of the holding device is achieved. In addition, the spring behavior of the retaining element with the associated support arm is not adversely affected or stiffened.

In this case, embodiments according to claim 28 or 29 prove advantageous because a safer and, above all, more uniform retention of the medical device in the receiving device is achieved.

According to claim 30, an additional centering of the medical device during its insertion into the receiving device is achieved at least partially between the holding devices in the immediate vicinity thereof. As a result, a centric puncture of the cannula is ensured by the closure device. In addition, however, a safer locking of the holding elements is achieved with the medical device. It is also possible an embodiment according to claim 31, as this over the entire insertion length of the medical device into the receiving device there is no jamming or no misadjustment of the cannula in the Dichtungsvoirichtung.

The embodiment according to claim 32 is advantageous, since only in certain areas a guide is created between the medical device and the receptacle during the insertion movement into the receptacle. If the dislocations of the guide surface aligned parallel to the longitudinal axis, a simple Längsfuh-tion can be achieved during the entire intended use here, whereby the reliability is significantly increased.

Finally, however, an embodiment as described in claim 33 is possible, since this already sufficient pre-centering of the medical device can be done with the closure device relative to the held in the receiving device cannula. As a result, an almost centric puncture is achieved by the closure device, in particular the sealing element.

By way of 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, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the various exemplary embodiments shown and described can also represent separate, inventive or inventive solutions. 1 to 6, a possible embodiment of a receiving device 1 for receiving a medical device 2, in particular a blood sampling tube 3 of a blood collection device, is shown. The medical device 2 can furthermore also be used for receiving body fluids, tissue parts or tissue cultures and, in turn, comprises a receiving vessel 4 shown in simplified form as well as at least one closure device S, with which at least one end region of the receiving vessel 4 is closed.

The receiving device 1 in turn comprises a receptacle 6 with a container jacket 7, the distance from each other in the direction of a longitudinal axis 8 forms a proximal end 9 and a distal end 10. Here, the proximal end 9 is to be understood as referring to the patient to whom the receiving device 1 is turned during the intended use.

Furthermore, the receptacle 6 comprises an end wall 11 arranged at least in regions in the region of the proximal end 9. The container casing 7 and the end wall 11 define a receiving chamber 12. The distal end 10 of the receptacle 6 is open in this embodiment and the medical device 2 , starting from the distal end 10 in the direction of the proximal end 9, are pushed into the housing chamber 12. The receiving chamber 12 is preferably formed in its cross section circular with respect to the longitudinal axis 8 and can, starting from the open distal end 10 toward the proximal end 9 at least in the N2006 / 14100 14/07 '06 FR 14:37 [SE / EM NO 7058] 1 4-7-06; 14: 35 OEPA CENTRAL # 13/41

• Be rich of its outer surface 13 be conically tapered, as is customarily carried out in plastic molded injection molded parts • ·················································· Furthermore, the receiving chamber 12 defines a clear cross section 14 in a plane oriented perpendicular to the longitudinal axis 8 or in a direction perpendicular thereto. This clear cross section 14 is to be formed as a function of the medical device 2 to be accommodated in the receiving channel 11.

Furthermore, the receiving device 1 also comprises a needle assembly 13 to be fastened to the receptacle 6, which is formed by a double-ended cannula 16 in the present exemplary embodiment. The cannula 16 is further associated with a needle holding part 17, with which the needle assembly IS can be coupled in the region of the end wall 11. Irrespective of this, however, it would also be possible to mold the cannula 16 directly during the manufacture of the receptacle 6 with it in one operation or to glue the cannula in the region of the end wall 11 to the receptacle 6.

One end of the needle assembly protrudes after the arrangement of the receptacle 6, starting from the end wall 11 in the Aufhahmekammer 12 into it. To protect against the escape of disposed within the cannula 16 remaining amounts of liquids that part of the cannula 16, which projects into the Aufhahmekammer 12, in a known manner a stocking shaped protective cover 18 made of an elastically deformable, pierceable, and self-closing material assigned.

In order to establish a flow connection between the cannula 16 and an inner space 19 of the receptacle 4, it is necessary to insert the medical device 2 into the receiving chamber 12 of the receptacle 6 until the end of the cannula 16 protruding into the receiving chamber 12 passes through an elastically deformable sealing element 20 of the closure device 5 passes through, so as to subsequently produce the flow connection. In this case, the sleeve-shaped protective sleeve 18 is also pierced and pushed along the cannula 16 together. Due to the material of the hull-shaped protective sheath 18 inherent, elastic and spring-back properties, it may happen that the medical device 2 by the prestressed, hull-shaped protective sleeve 18 so far from the Aufhahmekammer 12 in N2006 / I4100 14/07 '06 FR 14 : 37 [SE / EM NR 7058] 7-06; 14: 35; 1 # 14/41

Direction of the open distal end 10 is adjusted so that the flow connection between the cannula 16 and the interior 19 is interrupted. This unintentional relative adjustment movement between the receiving device 1 and the inserted medical device 2 can also be supported by a coating which improves the sliding properties of the cannula 16 and thus reduces the ranking. This coating serves to facilitate the puncture process by the sealing element 20 of the medical device 2. This can occur when the user of the Aufiiah-meeinrichtung 1 is not in mutual position fixation between the receptacle 6 and the medical device 2 when standing in flow-connected interior 19 with the cannula 16.

In order to avoid unintentional pushing out of the medical device 2 from the receiving chamber 12, the receiving device 1 is further associated with a holding device 21, which is formed by a part of the container shell 7. The holding device 21 in turn comprises at least one holding element 23 projecting beyond an inner surface 22 of the container jacket 7 in the direction of the longitudinal axis 8. The holding element 23 is designed such that it projects from a clear cross-section 14 of the receiving chamber 12 is designed to be automatically adjustable with the medical device 2 engaged locking position in a release of the medical device 2 releasing position. This adjustment or displacement between the two positions takes place by means of a relative adjustment movement in the direction of the longitudinal axis 8 between the medical device 2 to be used and the container jacket 7 in the radial direction with respect to the longitudinal axis 8. The holding element 23 projecting into the clear cross section 14 becomes Area of the holding member 23 a comparison with the clear cross-section 14 lesser cross-section or clearance defined and so the medical device 2 relative to the receptacle 6 in its inserted into the receiving chamber 12 position held or fixed until a conscious unlocking and connected a release of the medical device 2 from the receptacle 6 takes place.

In addition to the sealing element 20, the closure device S can also have a cap 24 comprising the same. The cap 24 has in a known manner a cap N20O6 / 14I00 14/07 '06 FR 14:37 [SE / EM NR 7058] 1 4-7-06; 1 4: 35 OEPA CENTRAL # 15/41 ····························· On which a cap edge 26 is formed on the side facing the receptacle 4.

The holding element 23 is arranged so far away from the end wall 11 of the receptacle 6 that the holding element 23 engages behind the cap edge 26 of the medical device 2 to be inserted into the receiving chamber 12 on the side facing the open distal end 10 of the receptacle 6. This ensures that, on the one hand, the sealing element 20 is completely pierced by the cannula 16 projecting into the receiving chamber 12 and, on the other hand, the entire medical device 2 can not inadvertently be pushed out of the receiving chamber 12 by the sleeve-shaped protective sheath 18 against the insertion direction.

In order to favor the holding element 23 of the holding device 21 in its relative movement relative to the stationary container casing 7, it is advantageous if this is associated with at least one support arm 27. This support arm 27 may extend from the proximal end 9, ie from the region of the end wall 11, towards the distal and open end 10 of the receptacle 6, wherein the support arm 27 is connected to the Be-hältermantel 7. The support arm 27 is in turn part of the container shell 7 as well as the holding element 23. To determine the suspension properties of the support arm 27, this has a wall thickness 28 which corresponds to a maximum wall thickness 29 of the container shell 7. Preferably, however, the wall thickness 28 of the support arm 27 is selected to be smaller, in order not to increase too much with sufficient retention force of the support members 23 for the medical device 2 to be applied to the user of the Aufnahmeeinrich-1 separation force. As a result, a jerky extension of the medical direction 2 from the receiving device 1 is avoided and nevertheless achieved in the held position of the medical device 2 within the receiving device 1, a secure support.

To facilitate this Ausschwenkbewegung to release the medical device 2, it is advantageous if the holding member 23 and / or the support arm 27 is at least partially connected via a foil-like, elastic connecting part 30 with the container shell 7 or are. For this purpose is further between the holding member 23 and / or the support arm 27 and the container shell 7 at least partially a slot N2006 / 14100 14/07 '06 FR 14:37 [SE / EM NR 7058] t 4.- 7-06; 14:35 OEPA CENTRAL # 16/41 ·· ·· ···· ·· • · • · · • • • • • • • • • • • • • • • Is arranged with these limiting slot walls 32, 33. This slot 31, the container shell 7 and its container wall completely enforce, but also additionally in this slot 31, the previously described connecting part 30 may be provided or arranged, as schematically simplified from a synopsis of Figs. 4 and 6 to see is and this connecting part 30 is indicated in Fig. 6 in dotted lines. With the arrangement of this connecting part 30, it is possible on the one hand to allow a sufficient radial adjustment of the holding member 23 with respect to the largest cross-section 14 of the receptacle 6 and on the other hand still form a completely enclosed Aufhahmekammer 12, provided that the connecting member 30 arranged continuously in the slot 31 or formed is. The necessary radial adjustment forces for the relative displacement of the holding element or elements 23 and optionally the support arm or arms 27 relative to the container shell 7 depend on the wall thickness of the film-like, elastic connecting part 30. However, this connecting part 30 could also be formed in the course of multi-component injection molding from a material different from the material of the receiving container 6. This material then has a high elongation at low stress and thus a lower modulus of elasticity than the container jacket 7. As a result, the connecting part 30 is made more elastic in its properties.

Due to the combined arrangement of the holding element 23 with the support arm 27, the slot 31 seen in the vertical direction on the longitudinal axis 8, an approximately U-shaped and preferably continuous longitudinal profile. Legs 34 of the U-shaped extending or aligned slot 31 extend from the holding element 23 in the direction of the closed proximal end 9 and the end wall 11. In addition, the legs 34 of the U-shaped slot 31 in the vertical direction on the Longitudinal axis 8 seen an expanding longitudinal course, which increases the distance between the legs 34, starting from the holding member 23 toward the junction of the support arm 27 with the container wall 7, increases. The slot has a width between the slot walls of between 0.3 mm and 2.0 mm, preferably between 0.8 mm and 1.2 mm. This not only a technically simpler shape for the Spritzgussvörgang is possible, but also prevents mutual jamming between the adjustable components and the fixed container wall.

If the elastic springback force of the above-described connecting part 30 is too great for the necessary release force of the medical device, then only a portion of a film-like cover element 35 can be arranged in the slot 31, as best seen in FIG. 6 in the right-hand part is. In this case, the cover member 35 is connected to only one of the slot 31 delimiting slot wall 32,33. In the present exemplary embodiment, the cover member 35 is connected to the slot wall 32 and arranged thereon, which is formed by the container shell 7. In this case, the film-like covering element 35 preferably extends only in part between the mutually spaced apart slot walls 32, 33 in order to be able to form this shape-technically more favorably. Thus, the film-like cover member 35 extends, starting from the container casing 7 in the direction of the holding device 23 and the support arm 27. However, it would also be possible independently to arrange the film-like cover member 35 on the holding device 23 and / or on the support arm 27 , so that this extends in the direction of the container shell 7. Regardless of this, however, a cover element 35 could also be arranged on each of the two slot walls 32, 33, which then extends in the direction of the respective opposite slot wall 32, 33 and preferably ends before it. With appropriate design and arrangement, the two cover 35 may overlap in the slot 31, whereby on the one hand a simple adjustment of the holding device 23 and / or the support arm 27 and on the other hand, a nearly completely closed receiving chamber 12 can be achieved.

As can now best be seen from FIG. 6, the retaining element 23 also has a wall thickness 36 which corresponds at most to the wall thickness 29 of the container jacket 7. Preferably, however, the wall thickness 36 by about 5 to 20%, but usually also 30 and 45% smaller than that of the remaining container wall 7 is selected. For example, the wall thickness 29 of the container wall 7 in the region of the open distal end can be approximately 0.8 mm. The wall thickness 28 of the support arm 27 and the wall thickness 33 of the support member 23 may be about 0.5 mm.

The holding element 23 is seen in cross-section - see Fig. 6 - formed in an approximately L-shaped and has converging legs on. This form is therefore chosen to

N2006 / 14IOO 14/07 '06 FR 14:37 [SE / EM NR 7058]

• Save plastic material in this area and achieve an approximately equal wall thickness of 28 and 36, respectively.

Thus, the holding element 23 on the side facing the distal end 10 on a guide surface 37, which tapers, starting mostly from the inner surface 22 and from the distal end 10 toward the proximal end 9. As a result, when the medical device 2 is inserted in the receiving chamber 12, this results in mutual contact and deformation of the support arm 27 connected to the holding element 27. The guide surface 37 encloses an angle 38 with the longitudinal axis 8, which is in one region with a lower limit of 10 °, preferably 20, in particular 30 ° and an upper limit of 35, preferably 45, in particular 50 °. This guiding surface 37, which generally runs relatively flat with respect to the longitudinal axis 8, thus facilitates the insertion of the medical device 2 into the receiving chamber 12 with simultaneous puncturing of the sealing element 20 of the closure device 5.

Furthermore, the retaining element 23 has on the side facing the proximal end 9 a retaining surface 39 which, starting from the proximal end 9, is designed to taper in the direction of the distal end 10. The holding surface 39 in turn encloses with the longitudinal axis 8 an angle 40 which is in a range with a lower limit of 40 preferably 50 °, in particular 55 ° and an upper limit of 65 °, preferably 70 °, in particular 75 ° , lies. This substantially steeper angle to the longitudinal axis 8 selected angle 40 forms on the one hand with its holding surface 39 sufficient support and on the other hand, the medical device 2 in turn from the receiving chamber 12 pull out without doing the closure device 5, in particular their cap 24, and optionally the sealing element 20 is withdrawn from the blood sampling tube 3.

Furthermore, it is advantageous if a transition region between the holding surface 39 and the guide surface 37 is formed starting from the holding surface 39 almost sharp-edged or only with a slight rounding, so as to achieve an additional latching or holding action. Because the receiving device 1 is basically a disposable article,

Preferably, the holding device 21 a plurality of, the inner surface 22 of the container shell 7 superior support members 23. In the present embodiment, two diametrically opposite to the longitudinal axis 8 opposite holding elements 23 are provided.

4, the connecting piece or the transition region between the support arm 27 and the container jacket 7 faces the proximal end 9 or is assigned to the latter in its next region. Depending on the puncture path of the cannula 16 in the sealing element 20, the holding element 23 is arranged approximately at the end of the front third, starting from the proximal end 9 in the direction of the distal end 10, at a distance therefrom. In order to achieve alignment of the medical device 2 to be used with respect to the longitudinal axis 8 and the holding element or elements 23 for the puncturing operation and the holding process to take place later, it is advantageous if the inner surface 22 of the container skirt 7 facing the longitudinal axis 8 at least in the region of the holding device 21 This guide device 41 preferably acts together with the end region of the medical device 2 which is closed by the closure device S, for example for the medical device 2 to be inserted into the receiving chamber 12. In this case, for example, the guide surface 42 of the container casing 7 may be cylindrical, resulting in a slight thickening of the wall thickness 29 in this area relative to the remaining container casing 7. As a result, since this receiving device 1 is an injection-molded part, it is designed for easier removal from the mold with the usual draft deviations, which lie, for example, in a range of 0.5 to 3 °. Furthermore, the guide surface 42 projects beyond the holding element 23 in the direction of the open distal end 10.

The guide surface 42 of the guide device 41 could, however, independently of this, as shown schematically simplified in FIG. 7, be formed by an offset 43 of the container jacket 7 directed in the direction of the longitudinal axis 8. This offset 43 only forms a deformation of the container jacket 7, whereby the arrangement N2006 / 14100 14/07 '06 FR 14:37 [SE / EM NR 7058] t 4-7-06; 14:35 OEPA CENTRAL; 1 # 20/41 ··························································································································································································································· Ribs on the inner surface 22 and associated excessive accumulation of material is avoided.

With appropriate mutual arrangement or dislocation - in the present case of 90 ° - with respect to the respective opposing holding elements 23 and guide surfaces 42, there is always a safe access to the holding element 23 with the medical device to be accommodated therein 2. A lateral sliding during the on Setting movement of the medical device 2 in the Aufhahmekammer 12 is thereby prevented. The longitudinal extension of the displacements 42 in the direction of the longitudinal axis 8 is again to be chosen so that even before the insertion process of the cannula 16 in the sealing element 20 is already a guide the medical device 2 relative to the receptacle 6.

The dislocations 43 of the container jacket 7 described above can be used, for example, if the basic outer shape of the receiving container 6 of the receiving device 1 is to be retained, but the receiving chamber 12 is to receive different sized medical devices 2 in its cross section. This can be done by appropriately trained inserts in the forming tool a simple conversion, without the need for a completely new mold must be made. FIGS. 8 to 11 show a further possible and, if appropriate, independent configuration of the receiving device 1 with at least one retaining device 21 formed thereon, wherein the same reference numerals or component designations for the same parts, as in the preceding FIGS. be used. In order to avoid unnecessary repetition, reference is made to the detailed description, in the preceding Figs. 1 to 7, respectively.

This receiving device 1 in turn comprises the receptacle 6 with the container casing 7, the distance from each other in the direction of the longitudinal axis 7 forms a proximal end 9 and a distal end 10. Furthermore, the receptacle 6 comprises an end wall 11 arranged at least in regions in the region of the proximal end 9. The container casing 7 and the end wall 11 define the receiving chamber 12. The distal end 10 of the receptacle 6 is also N2006 / 14100 14/07 '06 in this exemplary embodiment FR 14:37 [SE / EM NO 7058] 14- 7-06; 14: 35 OEPA CENTRAL # 21/41

The container casing 7 has on the side facing away from the Aufhahmekammer 12 side, the outer surface 13, as well as on the receiving chamber 12 side facing the inner surface 22 on.

In the region of the proximal end 9, the receiving chamber 12 again has the guide device 41 with at least one guide surface 42 for the relative mutual positional positioning of the medical device 2 to be inserted into the receiving chamber 12. This in turn results in a mutual alignment between the medical device 2, in particular its sealing element 20, and the cannula 16 penetrating it.

In order to prevent the inserted into the receiving chamber 12 and during normal use to be held medical device 2 from accidental ejection or falling out of the Aufhahmekammer 12, here again the holding device 21 is provided, which structurally different from the previously shown Ausfüh- tion example is lolled to.

The holding device 21 shown here in turn comprises the holding element 23, which is arranged on the support arm 27 in the present embodiment. The support arm 27 is formed shorter in contrast to the embodiment described above in its extending in the direction of the longitudinal axis 8 length. The support arm 27 with the protruding in the direction of the longitudinal axis 8 holding member 23 is formed in the region of its outer periphery on three sides of the U-shaped slot 31 separated from the rest of the container wall 7. The connection with the container shell 7 takes place on the side facing away from the holding member 23 and the proximal end 9 facing portion of the support arm 27. The U-shaped extending slot 31 in turn has the two legs 34, which towards the proximal end. 9 , starting from the holding element 23, extend. The longitudinal course of the legs 34 can in turn be seen in the vertical direction on the longitudinal axis 8, have a widening longitudinal course. In this embodiment shown here corresponds to a length 44 of the leg 34 of the U-shaped slot 31 in approximately a Lfingserstreckung N2006 / 14100 14/07 '06 FR 14:37 [SE / EM NR 7058] 1 4-7-06; 14:35; 1 # 22/41

Between the slit walls bounding the slot 32, 33, the film-like cover member 35 may again be arranged at least in some areas, which is here connected to the slit wall 32 delimiting the slot 31, in particular formed thereon. This cover element 35 serves to further minimize the access cross section from the outer surface 13 to the receiving chamber 12 in the region of the slot 31.

The support arm 27 has a wall thickness 28 with respect to the wall thickness 29 of the container jacket to 28 small wall thickness. Thus, an outer surface 46 formed on the support arm 27 on the side away from the receiving chamber 12, with respect to the outer surface 13 of the container shell 7, may be offset from it in the direction of the receiving chamber 12. This has the advantage that due to the areally relatively small design of the holding device 21 with respect to the surface 13 when hands or holders of the receiving device 1 of the operator no unintentional displacement or adjustment of the holding device 21 takes place. Likewise, however, an overhanging of the outer surface 13 is prevented or minimized even during the snap-in or release operation of the medical device 2 by the receiving device 1 in the course of the common adjustment movement of the support arm 27 with the holding element 23 arranged thereon.

As can best be seen from FIG. 10, in this exemplary embodiment the holding element 23 again has the guide surface 37 facing the distal end and the holding surface 39 facing the proximal end 9. With respect to the longitudinal axis 8, the guide surface 37 or holding surface 39 in turn close the previously described in detail angle 38,40, which are within the limits specified therein. Preferably, the angle 38, for example, a size of 46 ° and the angle 40 of 70 °.

In contrast to the embodiments previously described in FIGS. 1 to 7, here, the holding member 23 is formed as a solid body, whereby the support arm 27 may be formed in the region of its outer surface 46 planar over. N2006 / 14I00 14/07 '06 FR 14:37 [SE / EM NO 7058] 1 4-- 7-06 ί 14:35 OEF »A CENTRAL # 23/41 · ♦ · ······ · In this case, in FIG. 10, it is indicated in simplified form that in the transition region between the.. Holding surface 39 and the guide surface 37, a transition radius 47 is formed. This transition radius 47 can be kept relatively low and, for example, be 0.3 mm.

The receiving device 1 with its clear cross section 14 is designed such that a recording of different dimensions having medical devices 2 is possible. Currently, blood sampling tubes 3 having a nominal dimension of 13 mm and 16 mm, respectively, are commonly used. Due to these different dimensions of the receiving vessel 4, the respective closure devices 5 also have mutually different external dimensions in the plane aligned perpendicular to the longitudinal axis 8. In order not to have to provide different receiving devices 1 for the different medical devices 2, the guide device 41 is formed in the receiving device 1 such that it ensures sufficient guidance and positioning for both nominal dimensions.

When dimensioning the closure devices S, in particular the caps 24, it was attempted in the case of the different nominal dimensions of the medical devices 2 to form the respective outer dimensions of the closure devices 5 with only slight dimensional differences.

The retaining forces of the holding device 21 for fixing the medical device 2 relative to the receiving device 1 can be effected by varying component dimensions. The restraint forces may be defined by determining a so-called pull-out force necessary to release the medical device 2 set in the holding device 1 by the holding device 21. The size or the extent of the restraining force or the pull-out force to be applied by a user may be a lower limit of 1N, preferably 2N, up to an upper limit of 5N, preferably ION, which also depends on the dimension of medical device 2 is dependent. For example, if a medical device is used with a nominal size of 13 mm, the retention or. Pull-out force 2 N. For the same receiving device 1, but a medical device 2 with a nominal dimension of 16 mm, the retention force or the withdrawal force can be 5.5 N. N2006 / I4100 14/07 '06 FR 14:37 [SE / GM NO 7058] 1 4 - 7-06; 14: 35 OEPA CENTRAL; 1 # 24/41 ♦ ··· ♦♦♦ · t · • · · · · · · · · · · · · ···········································································

The retention or extraction forces described above can be set and determined by varying the length or longitudinal extent of the support arm 27 and / or the wall thickness 28 of the support arm 27 and / or the formation of the support member 23 itself. If the support arm 27 and the leg or legs 34 connected thereto are relatively short and the wall thickness 28 is chosen to be relatively high, the retention or extraction forces are increased by the higher deformation resistance. The same also applies to the choice of the angle 40 of the support surface 39 with respect to the longitudinal axis 8. The steeper the support surface 39 is inclined to the longitudinal axis 8, the higher the retention or extraction force. Furthermore, the restraining or the pull-out forces can also be influenced by the projection or the projection of the holding elements 23 into the clear cross-section 14 of the receiving chamber 12. All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

The embodiments show possible embodiments of the receiving device 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this possibility of variation due to the teaching of technical action representational invention in the skill of those skilled in this technical field. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the receiving device 1, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
