Description

Technical Field

[0001] The present invention relates to a tray for accommodating a plurality of medical hollow bodies.

[0002] Based on U.S. Patent No. 6,216,885, a tray for accommodating a plurality of syringes, particularly deep-drawn, made of a thermoformed plastic material is known. This known tray has extremely low rigidity and is thus difficult to handle. In order to enable handling of the tray, a plurality of holding pieces are provided at regular intervals, and the tray can be held, for example, by gripping with a vacuum gripper. The tray is designed to fit a specified syringe format and has a firm clamping element for stably and safely holding a syringe of the specified format. Therefore, the tray cannot be used flexibly for different syringe formats, and due to the clamping element for stably fixing the syringe, it is time-consuming to attach or remove the syringe from the tray.

[0003] Also known is a tray into which a medical hollow body is loosely inserted. This is particularly disadvantageous when the medical hollow body contains or consists of glass. In this case, contact between the glasses occurs, which may cause damage, particularly during transportation. Also, in this case, there is a risk of damage to the label placed on the medical hollow body or impairment of the label readability.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, the underlying problem of the present invention is to provide a tray for accommodating a medical hollow body in which the above-mentioned drawbacks are at least partially eliminated, preferably in which the above-mentioned drawbacks are not present.

Means for Solving the Problems

[0005] This problem is solved by the technical teachings of this specification, in particular the teachings of the independent claims and the teachings of the dependent claims and the embodiments disclosed in the specification being provided.

[0006] This problem is solved, in particular, by providing a tray for accommodating a plurality of medical hollow bodies. The tray has a bottom plate. The bottom plate has an upper surface and a lower surface. On the upper surface, a wall extending all around along the outer edge of the tray is arranged. The bottom plate and the wall define an accommodation volume for accommodating the medical hollow bodies. The tray has a finite length along the longitudinal direction and a finite width along the width direction extending perpendicular to the longitudinal direction. The tray has at least one holding structure for holding the medical hollow bodies. And this holding structure has a first holding wall. This first holding wall extends longitudinally from a first width section of the wall to an opposite second width section of the wall. In the first holding wall, first through-holes spaced apart from each other are formed. The holding structure further has a second holding wall that is spaced from the first holding wall by a first width interval and extends from the first width section to the second width section parallel to the first holding wall. In this second holding wall, second through-holes spaced apart from each other are formed. Each of these second through-holes is aligned with one respective first through-hole assigned to each of them. In particular, the second through-holes and the first through-holes are assigned to form pairs with each other, and the first through-holes and the second through-holes assigned to form pairs with each other are aligned with each other. The holding structure further has a row of spacers that are spaced from the holding wall by a second width interval, extend parallel to the holding wall, and are spaced apart from each other to form a plurality of voids. The spacers are arranged offset with respect to the through-holes such that each void is aligned with one respective first through-hole and one respective second through-hole. Accordingly, one void is assigned to each pair consisting of one first through-hole and one second through-hole. In this case, the corresponding void is aligned with each first through-hole and each second through-hole of each pair of a plurality of correspondingly assigned first and second through-holes. One holding position for one medical hollow body is defined by one respective void, the first through-hole assigned to this void, and the second through-hole assigned to this void and the first through-hole. This holding position extends in the width direction of the tray.The first width interval is shorter than the second width interval.

[0007] Due to a geometric structure comprising a bottom plate that defines a receiving volume together with walls extending over the entire periphery, the tray has high rigidity and can thus be handled in a simple and stable state simultaneously. In particular, the holding pieces that were previously required to be provided specifically for this purpose are no longer necessary, so the volume that was previously required to be provided for this purpose can be saved and it can be used to accommodate medical hollow bodies. The holding structure, depending on the holding position formed by the through-hole and the gap, enables the use of a large number of different types of medical hollow bodies, particularly various syringe types, in a very flexible manner regardless of whether a finger grip, a piston rod and / or an injection needle are pre-assembled. At the same time, the holding structure omits a firm clamping element, whereby a medical hollow body can be easily and quickly inserted into and removed from the tray, especially by hand or using a machine, particularly a robot. That is, this tray enables both the easy installation and the easy removal of medical hollow bodies. At the same time, the holding position provides a unique insertion pattern for subsequent processing of the medical hollow body. Furthermore, since the holding position defines unique spaced-apart regions for individual medical hollow bodies, contact between glasses is particularly avoided. This also eliminates the risk of damage to the medical hollow body and / or the label that may be arranged on the medical hollow body in some cases. In particular, when using the tray proposed in this specification, the readability of the label is not impaired.

[0008] In particular, with the tray proposed in the present specification, the exact number of inserted medical hollow bodies can be appropriately grasped. A number of medical hollow bodies of different forms and variations can be carried by just one tray. When using the tray proposed in the present specification in particular, different syringe forms with a piston rod and / or a finger grip and different syringe forms without a piston rod and / or a finger grip can be individualized. Due to the exact seating (passgenauen) provided by the holding position, lateral sliding of the medical hollow body during transportation is eliminated.

[0009] The bottom plate is preferably formed flat and horizontally. The bottom plate in particular does not have outward protrusions and / or bulges.

[0010] The tray is in particular not deep-drawn.

[0011] Preferably, the tray is manufactured by injection molding. In particular due to the robustness of the injection molding material, the tray can be used multiple times and in particular more frequently than a deep-drawn material. The tray can in particular be used as a recycled material.

[0012] On the one hand, by arranging the holding wall and on the other hand by arranging a spacer that forms a gap, placing the medical hollow body in the wrong orientation is eliminated.

[0013] The wall preferably extends at a 90° angle to the bottom plate. The wall in particular extends in the height direction starting from the bottom plate. This height direction extends perpendicular to the longitudinal direction on the one hand and perpendicular to the width direction on the other hand.

[0014] The longitudinal direction is preferably the longest extending direction of the tray. The width direction preferably corresponds to the direction in which the tray extends over a width shorter than the length along which it extends in the longitudinal direction. The height direction is the vertical direction, i.e., the direction extending in the geodesic height direction, especially when the tray is arranged as specified. In contrast, the longitudinal direction and the width direction extend in a plane in the height direction, i.e., a plane in which a vertical line extends vertically in space, when the tray is arranged as specified.

[0015] The wall preferably extends in the height direction up to at least the upper edge of the largest medical hollow body that can be inserted into the accommodation volume when the largest medical hollow body that can be inserted into the accommodation volume is inserted into the accommodation volume. Preferably, the wall extends above the upper edge of the largest hollow body when the largest hollow body to be inserted into the accommodation volume is inserted into the accommodation volume.

[0016] The retaining wall preferably has the same height as the wall in the height direction, i.e., it extends in the height direction from the bottom plate in particular up to the upper edge of the wall.

[0017] The through-hole is preferably open upward, i.e., it has an open end facing away from the bottom plate.

[0018] The tray has, in particular, the following tip sizes, i.e., For 1 ml, with a diameter of 8.15 mm, with and without a piston rod / finger grip, the glass body length with Vetter RNS (rigid needle shield) is 81.2 mm, and the glass body length with Vetter OVS is 73.9 mm. For 1.5 ml, with a diameter of 10.85 mm, with and without a piston rod / finger grip, the glass body length with RNS is 73.3 mm, and the glass body length with Vetter OVS is 63.5 mm. For 2.25 ml, with a diameter of 10.85 mm, with and without a piston rod / finger grip, the glass body length with Vetter RNS is 82.8 mm, and the glass body length with Vetter OVS is 75 mm. It can be used according to the tip size. As the closure member, Vetter OVS, Vetter TipCap, Vetter NS (needle shield) and Vetter RNS may be used.

[0019] The length of the tray measured in the longitudinal direction is preferably at least 300 mm to at most 400 mm, preferably at least 325 mm to at most 375 mm, preferably 350 mm.

[0020] The width of the tray measured in the width direction is preferably at least 200 mm to at most 300 mm, preferably at least 225 mm to at most 295 mm, preferably at least 250 mm to at most 280 mm, preferably at least 265 mm to at most 275 mm, preferably 270 mm.

[0021] The tray is preferably formed as an insert in a container for insertion or fitting into a larger transport container. A plurality of such trays can be inserted or fitted into the transport container. The dimensions of the tray, in particular the length and width of the tray, are preferably dimensioned such that two such trays can be placed side by side and inserted into the transport container. The height of the tray is in particular dimensioned such that a plurality of trays, in particular more than two trays, preferably four or more trays, can be stacked and inserted into one such transport container.

[0022] The height of the tray measured in the height direction is from the lower edge of the bottom plate to the upper edge of the wall at least 15 mm to at most 30 mm, preferably at least 17.5 mm to at most 25 mm, preferably at least 20 mm to at most 23 mm, preferably 22 mm. If the tray additionally has leg elements, the height of the tray including these leg elements is preferably at least 23 mm to at most 30 mm, preferably at least 24 mm to at most 28 mm, preferably 26 mm.

[0023] The first width interval is preferably at least 6 mm to at most 12 mm, preferably 9 mm. The second width interval is preferably at least 26 mm to at most 30 mm, preferably 28 mm. The third width interval is preferably at least 36 mm to at most 42 mm, preferably 39 mm. Only one of the plurality of gaps preferably has an extension length of at least 6 mm to at most 12 mm, preferably 9 mm, measured in the longitudinal direction of the tray, that is, has an inner method width. Preferably, all the gaps are formed identically.

[0024] According to an improved form of the present invention, the tray has two holding structure parts as at least one holding structure part, and these two holding structure parts are arranged side by side in the width direction and are separated from each other by a partition wall extending from the first width section to the second width section in the longitudinal direction. That is, the tray has two holding structure parts in total. In this case, in particular, the two holding positions are also arranged side by side in the width direction. Therefore, the tray can accommodate two rows of medical hollow bodies arranged side by side in the width direction. This means that the hollow bodies in both rows are paired with each other and are arranged one behind the other in the tray when viewed in the longitudinal direction of the hollow body. Thus, the tray can accommodate a large number of medical hollow bodies extremely functionally and neatly.

[0025] The partition wall preferably extends up to the upper edge of the wall in the height direction, that is, is formed at the same height as the wall.

[0026] According to an improved form of the present invention, it has been identified that the first retaining wall of at least one retaining structure is spaced apart by a third width interval from an end wall selected from the longitudinal section of the wall and the separating wall. This preferably applies to both retaining structures of the tray when the tray has two retaining structures. In this case, in one of the two retaining structures, the end wall is the longitudinal section of the wall, and in the other of the two retaining structures, the end wall is the separating wall that separates the two retaining structures from each other. Advantageously, when the medical hollow body has its piston rod, such a piston rod can be accommodated in the region arranged between the first retaining wall and the end wall.

[0027] According to an improved form of the present invention, it has been identified that the width sections of the wall each have a cavity between the second retaining wall and the row of spacers. This cavity advantageously enables easy engagement with a gripper or, in the case of using the hand, with the hand, for example a finger, whereby a medical hollow body, especially one arranged on the edge side, can be reliably and easily inserted into the tray and also removed again.

[0028] The cavity is preferably open upwards, that is, it has an open end opposite the bottom plate.

[0029] According to an improved form of the present invention, it has been identified that the bottom plate has a convex portion in the region of the row of spacers. In particular, the bottom plate may have a shape different from the plane in the region of the spacers, particularly an upwardly curved portion. The spacer is disposed on the convex portion. Since this convex portion provides a placement area for the medical hollow body stepped from the remaining bottom surface of the tray in the region of the gap, the medical hollow body is not placed on the bottom surface, particularly in the region between the second holding wall and the row of spacers. In this case, the hollow body can be particularly easily captured, particularly grasped there. Furthermore, the convex portion structurally reinforces the tray, whereby the tray has particularly high stability. On the lower surface of the bottom plate, the upper convex portion forms a concave portion, and this concave portion enables particularly simple grasping and handling of the tray itself, whether by hand or by machine. In particular, the convex portion formed on the upper side forms an engagement groove on the lower side, and this engagement groove enables particularly easy removal of the tray from the transport container.

[0030] According to an improved form of the present invention, it has been identified that the spacer is formed in an elongated shape when viewed in plan view. This constitutes a configuration that can be particularly simply and easily manufactured for the spacer.

[0031] Alternatively, preferably, it has been identified that the spacer is formed in a cross shape when viewed in plan view. Thereby, the spacer satisfies an additional function with respect to separating the medical hollow bodies by contributing to the reinforcement and thus the stability of the tray based on its cross-shaped structure. In particular, based on this structural reinforcement, high stacking of a large number of trays on each other is possible.

[0032] According to an improved form of the present invention, it is specified that the bottom plate has leg elements on its lower surface. In a preferred configuration, the tray may have four leg elements on the lower surface of the bottom plate, particularly one leg element at each corner. The leg elements protrude from the lower surface (geodesically downward). Thus, the leg elements form upright elements that can make the tray stand up. In this case, the lower surface of the bottom plate is spaced apart from the upright plane on which the tray stands. Preferably, the leg elements are arranged offset inwardly by at least a part of the wall thickness from the outer edge of the bottom plate. Particularly preferably, the leg elements are arranged offset inwardly exactly by the wall thickness. In particular, this enables stable stacking of multiple trays on top of each other. In this case, the leg elements of the tray located on the upper side engage within the accommodation volume of the tray located on the lower side, and preferably, in a stable state, they are in contact with the inner surface of the wall. This particularly precise seating of the leg elements effectively prevents, preferably, the stacked trays from sliding relative to each other.

[0033] According to an improved form of the present invention, it is specified that the tray is formed of an integral and consistent material. Thus, the tray can be manufactured particularly simply and inexpensively, particularly by injection molding.

[0034] Preferably, the tray is formed of an integral and consistent material, preferably plastic. Thus, the tray can be manufactured particularly simply and inexpensively, particularly by injection molding. The plastic is preferably selected from the group consisting of autoclave - treatable plastic, machine - washable plastic, acrylonitrile - butadiene - styrene copolymer (ABS), polycarbonate, and polypropylene. In particular, these plastics enable particularly simple cleaning of the tray by a washing machine. In this case, the tray is preferably also autoclave - treatable. In particular, this enables the reuse of the tray, particularly its use in a recycling process.

[0035] In addition, the present invention includes a tray belonging to the present invention or a tray described in one of the above-described plurality of embodiments, and a predetermined medical hollow body, particularly a combination of the tray with a predetermined medical hollow body among the above-described plurality of medical hollow bodies that can be preferably used together with the tray. The medical hollow body has a cylindrical section and a flange region. When the medical hollow body is disposed within the tray, the flange region is disposed between a first retaining wall and a second retaining wall. In this case, the flange region preferably engages with the rear side of the second through-hole assigned to the medical hollow body among the second through-holes. The cylindrical section extends into the void assigned to the second through-hole assigned to the medical hollow body through the second through-hole in the width direction of the tray. Thus, the medical hollow body is stably and safely held within the tray. In particular, the medical hollow body neither slides laterally within the tray nor contacts another medical hollow body housed within the tray. Thus, contact between the glasses is particularly avoided between the medical hollow bodies disposed within the tray.

[0036] The flange of the medical hollow body may particularly be a finger grip or a backstop. The medical hollow body is disposed with play, at least within the void and possibly at least within the second through-hole (particularly depending on its outer diameter). The dimensions of the tray are preferably adapted to the largest medical hollow body to be disposed within the tray, and thus this largest medical hollow body can be placed in the holding position with just a slight play, without a firm clamp. When the medical hollow body is formed as a syringe, the injection end of the syringe is preferably disposed between the row of spacers and the rear end wall. In this case, the rear end wall is selected from the longitudinal section of the wall and the separating wall depending on to which holding structure the row of spacers is assigned. Thus, the separating wall becomes the rear end wall particularly for the first holding structure of both holding structures, and the front end wall for the second holding structure of both holding structures.

[0037] According to an improved form of the present invention, it has been identified that the piston rod of the medical hollow body extends in the direction of the end wall through the first through portion. Therefore, the third width interval is provided particularly for arranging the piston rod.

[0038] Hereinafter, the present invention will be described in detail with reference to the drawings.

Mode for Carrying Out the Invention

[0040] FIG. 1 shows a first example of a tray 1 configured to accommodate a plurality of medical hollow bodies. This tray 1 has a bottom plate 3 having an upper surface 5 and a lower surface 7. On the upper surface 5, a wall 11 extending all around along the outer edge 9 of the tray 1 is arranged. The bottom plate 3 and the wall 11 define an accommodation volume 13 for accommodating the medical hollow body. The tray 1 has a finite length along the longitudinal direction L and a finite width along the width direction B extending perpendicular to the longitudinal direction L. The tray 1 further has a holding structure 15 for holding the medical hollow body.

[0041] In the illustrated configuration, the tray 1 particularly has a first holding structure 15 and a second holding structure 15'. Since both of these holding structures 15, 15' are formed identically, hereinafter, only the configuration of the first holding structure 15 will be described in detail. The corresponding elements of the second holding structure 15' are illustrated with symbols with apostrophes respectively.

[0042] The holding structure 15 has a first holding wall 17. This first holding wall 17 extends in the longitudinal direction L from the first width section 21 of the wall 11 to the opposed second width section 23 of the wall 11. The first holding wall 17 is formed with first through-holes 25 spaced apart from each other. The holding structure 17 further has a second holding wall 19 spaced from the first holding wall 17 by a first width interval ΔB1. This second holding wall 19 extends from the first width section 21 to the second width section 23 in parallel with the first holding wall 17. The second holding wall 19 is formed with second through-holes 27 spaced apart from each other. Each of the second through-holes 27 is aligned with one of the first through-holes 25 assigned to each of them. The holding structure 15 further has a row 29 of a plurality of spacers 33 spaced from the holding walls 17, 19 by a second width interval ΔB2. This row 29 extends in parallel with the holding walls 17, 19, and the spacers 33 are spaced apart from each other, forming a plurality of voids 31. The spacers 33 are arranged shifted with respect to the through-holes 25, 27 such that each of the voids 31 is aligned with one of the first through-holes 25 and one of the second through-holes 27. Thus, one holding position 35 for one medical hollow body is defined by one of the voids 31, the first through-hole 25 assigned to this void 31, and the second through-hole 27 assigned to this void 31. This holding position 35 extends in the width direction B.

[0043] The first width interval ΔB1 is shorter than the second width interval ΔB2.

[0044] The first holding structure 15 and the second holding structure 15' are arranged side by side in the width direction B and are separated from each other by a partition wall 37 extending in the longitudinal direction L from the first width section 21 to the second width section 23.

[0045] The first retaining wall 17 is spaced apart from the end wall 39 by a third width interval ΔB3. In this case, the end wall 39 is the longitudinal section 41 of the wall 11. Similarly, the first retaining wall 17' of the second retaining structure 15' is also spaced apart from another end wall 39' by a third width interval ΔB3. In this case, the other end wall 39' is the separating wall 37.

[0046] The width sections 21, 23 of the wall 11 each have a cavity 43 between the second retaining wall 19 and the row 29 of spacers 33.

[0047] The bottom plate 3 has a protruding portion 45 in the region of the row 29 of spacers 33. In this case, the spacer 33 is arranged on this protruding portion 45.

[0048] In the first embodiment shown in FIG. 1, the spacer 33 is formed in a cross shape as viewed in plan view.

[0049] The bottom plate 3 has leg elements 47 protruding from its lower surface 7. These leg elements 47 are preferably displaced inwardly by at least a part of the wall thickness of the wall 11, preferably by the wall thickness, from the outer edge 9 of the bottom plate 3.

[0050] The tray 1 is formed, in particular, integrally and from a consistent material, preferably from plastic. This plastic is preferably selected from the group consisting of autoclave-treatable plastic, machine-washable plastic, acrylonitrile-butadiene-styrene copolymer, polycarbonate, and polypropylene.

[0051] FIG. 2 shows a cross-sectional view of the tray 1 according to the first embodiment along the line A-A shown in FIG. 1. In FIG. 2, in particular, the first width interval ΔB1, the second width interval ΔB2, and the third width interval ΔB3 are indicated. Furthermore, it is indicated in FIG. 2 that the height of the tray 1 including the leg elements 47, measured in the height direction, is 26 mm. Note that the height excluding the leg elements 47 is 22 mm.

[0052] Figure 3 shows a plurality of trays 1 according to a second embodiment stacked on top of each other in combination with a plurality of medical hollow bodies 49. The same elements and functions are denoted by the same reference numerals as those of the same elements, so for this, please refer to the above description. However, for clarity, only one hollow body 49 is provided with the corresponding reference numeral, and other reference numerals related to this hollow body 49 are also provided.

[0053] In particular, the leg elements 47 enable stable stacking of the plurality of trays 1 with each other without the risk of the individual trays 1 slipping laterally relative to each other. For this purpose, in particular, the leg elements 47 of the trays 1 located on the upper side are engaged in the accommodation volume 13 of the trays 1 located on their lower side, and preferably, they are in contact with the inner surface of each wall 11.

[0054] In this second embodiment of the tray 1, the spacers 33, 33' are formed elongated as seen in plan view.

[0055] The medical hollow body 49 is formed as a syringe in particular in this specification. Hereinafter, only one medical hollow body 49 will be described in detail. The medical hollow bodies 49 are preferably formed identically or at least similarly to each other in this specification. The medical hollow body 49 to be considered in detail in this specification has a cylindrical section 51 and a flange region 53. This flange region 53 is arranged between the first holding wall 17 and the second holding wall 19. In this case, the flange region 53 is engaged behind the second through portion 27 assigned to the medical hollow body 49. The cylindrical section 51 extends into the gap 31 through the second through portion 27 in the width direction B of the tray 1. This gap 31 is assigned to the second through portion 27, and this second through portion 27 itself is assigned to the medical hollow body 49.

[0056] The piston rod 55 of the medical hollow body 49 extends in the direction of the end wall 39 through the first through portion 25.

[0057] The flange region 53 is preferably formed as a finger grip or a backstop.

[0058] However, unlike the drawings selected in this specification, a medical hollow body 49 that has not yet been assembled, that is, in particular, that does not yet have a flange region 53 and / or a piston rod 55, may be accommodated in the tray 1.
