Description

[Technical Field]

[0001] The present invention relates to a protective housing for a glass tag, a medical product, a connecting spring, a protective housing system, and a medical product system. [Background technology]

[0002] [Background of the invention] As the lifecycle management of sterile items becomes increasingly important in the future, there is a growing demand for the monitoring and traceability of these items, especially medical (surgical) instruments during the sterilization cycle. For this reason, all types of medical instruments are equipped with transponders, especially passive transponders using RFID (Radio Frequency Identification) or NFC (Near Field Communication) technology. This allows the location of the medical instrument to be determined at all times, and a decision can be made as to whether the medical instrument has (correctly) passed the entire reprocessing process or all maintenance steps. It also makes it possible to detect the number of sterilization cycles the sterile item has undergone and determine when the item's maximum useful life has been reached. The transponders in the form of glass tags are particularly advantageous.

[0003] [Prior art] Devices for attaching transponders to medical instruments are already known from the prior art. For example, in EP 2 087 850 A1, a transponder is attached to the medical instrument (e.g., its handle) using a housing, which has a cavity for receiving the transponder. The housing may consist of two separate parts, which can be connected to each other in a form-fitting manner after surrounding the transponder and the handle of the medical instrument in cutouts during the fixing process. As another fixing option, the transponder can be placed in a foldable protective housing via a hinge and then fixed to the medical instrument using a flexible strap (belt).

[0004] EP 3146477 A1 discloses a metallic fixing element for a metallic RFID tag. The fixing element is attached (glued) to the medical device via a flat base surface and holds a transponder via a two-sided cutout. The transponder and the fixing element are electrically conductively connected to each other, which can improve the strength and range of the transponder's signal, especially when attached to small objects.

[0005] Such transponder attachment can affect the handling and ergonomics of the sterile equipment by creating protrusions due to the transponder being attached to the outside of the medical article, making medical reprocessing or cleaning more difficult.

[0006] It is also known to attach transponders to the medical device housing, typically by gluing, potting, or welding, or in pre-drilled holes. However, these solutions are complex and require proper preparation of the medical device surface, such as ensuring that it is clean and oil-free. Furthermore, fixation of transponders by press-fit or gluing is not durable due to their plastic construction. Furthermore, such connections of transponders to medical devices make transponder replacement quite difficult.

[0007] In many cases, medical products only have a small wall thickness available to accommodate a transponder (e.g., a glass tag protected by a housing). This makes traditional snap-on fastening elements (e.g., snap buttons) difficult to implement due to the lack of required dimensions. Furthermore, certain instruments (e.g., motor-driven saws) are subject to high vibrations during operation, making such small snap-on fastening elements too delicate and likely to break in the long term.

[0009] SUMMARY OF THE INVENTION It is therefore an object of the present invention to obviate or at least mitigate the disadvantages of the prior art.

[0010] More specifically, the object of the present invention is to provide a method for interchangeably connecting a transponder, which may contain a unique identifier of a medical tool (medical instrument), to a medical tool (medical instrument), without altering the shape of the medical tool (medical instrument) in a manner that is protected from environmental influences and mechanical forces, and that would adversely affect its handling.

[0011] This object is solved by a protective housing according to claim 1, a medical product according to claim 3, a connecting spring according to claim 6, a protective housing system according to claim 8 and a medical product system according to claim 10.

[0012] In particular, the above object is achieved by a protective housing for accommodating a transponder, which can be received in a transponder receiving portion formed in the protective housing in a medical product (in particular a medical instrument and / or a pharmaceutical product in a sterilization cycle), the protective housing comprising (constitutes) a form-fit coupling device (coupling portion) in the form of a circumferential groove (protective housing groove) for receiving a connecting spring, and the connecting spring.

[0013] In other words, the above-mentioned object is solved by a protective housing and a transponder receiving part (transponder holder, transponder covering). The protective housing is provided and configured (separate) to be (permanently) installed on a medical product (medical tool) and for this purpose (integrally) comprises or constitutes a support device. The support device preferably has the form of at least one protective housing groove (engagement notch), at least one protrusion or a similar form-fit coupling device (coupling), and is provided and configured to engage with and be supported on the medical product (medical tool). The transponder receiving part is formed, configured or provided on the protective housing. The transponder receiving part is provided and configured so that a radio-readable transponder is inserted (is insertable) into the transponder receiving part.

[0014] For example, the protective housing may be configured around a radio-readable transponder such that the protective housing completely (particularly integrally) surrounds the transponder or the transponder receiving portion. Alternatively, the protective housing may include an opening through which the transponder can be inserted into the transponder receiving portion. The transponder is, in particular, a passive RFID tag with a glass tag structure. However, other types of radio-readable transponders (e.g., NFC tags) are also conceivable. The protective housing includes a circumferential protective housing groove in its outer peripheral wall. In other words, the protective housing groove extends around the entire circumference (annularly) of the protective housing and forms a channel-like recess in the outer peripheral wall of the protective housing. The protective housing groove is provided and configured to receive a connecting spring.

[0015] By forming the protective housing with a protective housing groove, the protective housing can be reversibly (detachably) connected to the medical tool (medical instrument) by a connecting spring. The connecting spring can absorb vibrations that occur during operation of the medical tool (medical instrument), thereby preventing damage to the transponder. The protective housing can also prevent mechanical, thermal, and chemical damage to the transponder.

[0016] In a first aspect, the protective housing groove may be configured to be coplanar or parallel to the central axis of the transponder receiving portion.

[0017] In other words, the transponder receiving portion may be a cylindrical recess. The transponder receiving portion has a central axis. The central axis of the transponder receiving portion and the protective housing groove may be arranged in the same plane. Alternatively, the central axis of the transponder receiving portion may be configured parallel to the plane in which the protective housing groove is arranged.

[0018] Such an arrangement of the protective housing groove and the transponder receiving portion can ensure that the transponder located in the transponder receiving portion is integrated into the medical tool in such a way that it is protected by the medical tool.

[0019] In another aspect, the protective housing may have a substantially pill-shaped geometry, and the protective housing groove may extend within a plurality of parallel walls that make up the pill-shaped geometry.

[0020] In other words, the protective housing groove extends substantially along the protective housing.

[0021] In another aspect, the parallel wall portion may have a first extension width (first length) in a height direction perpendicular to the same plane as the central axis of the protective housing or a plane parallel to the central axis, and the protective housing may have a second extension width (second length) in the height direction of the protective housing, and the first extension width may substantially coincide with the second extension width.

[0022] In another aspect, the protective housing may be configured to be substantially symmetrical with respect to a plane that is the same as the central axis or a plane that is parallel to the central axis.

[0023] Furthermore, the object of the present invention is solved by a medical product (in particular a medical instrument and / or a pharmaceutical product in a sterilization cycle) having a protective housing receiving part provided and configured to receive a protective housing and a transponder received in the protective housing, the protective housing receiving part comprising a wall groove for receiving a connecting spring in at least two parallel side walls of the protective housing receiving part.

[0024] In other words, the medical product comprises a protective housing receiving part consisting of two parallel side walls. One wall groove is provided in each side wall. The wall groove extends in particular over the entire length (entire longitudinal extent) of the parallel side walls. The wall groove extends in a depth direction perpendicular to the side walls, away from the receiving space (accommodation space) of the protective housing receiving part. The depth of the wall groove in the depth direction is constant over the entire length of the parallel side walls. The wall groove is provided and configured to be able to receive the connecting spring in a form-fitting manner.

[0025] Such protective housing receptacles in medical products are simple and inexpensive to manufacture, are easily accessible, and can be implemented as a retrofit solution to existing instruments.

[0026] In one embodiment, the protective housing receiver may be configured as a through opening in the medical product or in a wall of the medical product.

[0027] In other words, the protective housing receiver may connect a top surface or wall of the medical product to a bottom surface or wall of the medical product.

[0028] The protective housing receiver is configured so that the protective housing is easily inserted into and easily removed from the protective housing receiver.

[0029] In another embodiment, two parallel side walls of the protective housing receiving portion may be connected to each other via a semicircular portion (radial portion), and the wall groove may be interrupted (terminated) at the semicircular portion.

[0030] In other words, the width of the wall groove in the depth direction at the semicircular portions (radii) may gradually decrease from the parallel side walls, in particular may become zero. The longitudinal extent of the side walls may extend between the semicircular portions (radii).

[0031] This configuration of the wall grooves ensures that the connecting spring engages in a form-fitting manner with the protective housing receiving part in the area of ​​the parallel side walls, and that the connecting spring does not engage in a form-fitting manner with the protective housing receiving part of the medical tool in the semicircular part (radius part), which can significantly simplify the insertion and removal of the protective housing into the protective housing receiving part.

[0032] In another embodiment, a first distance from the wall groove to the top surface of the medical product may substantially match (correspond) a second distance from the wall groove to the bottom surface or wall of the medical product.

[0033] In other words, the wall groove is configured in the center of the protective housing receiving portion in the height direction.

[0034] Furthermore, the object of the present invention is solved by a connection spring for form-fitting fixing of a protective housing in a medical product, the connection spring having two legs and a front part connecting the legs, the connection spring being configured substantially in a U-shape.

[0035] In other words, the connecting spring is provided and configured to engage in a form-fitting manner with the wall groove of the protective housing receiving portion. At the same time, the connecting spring is provided and configured to engage in the protective housing groove of the protective housing. The connecting spring is configured in the shape of a clasp.

[0036] In one embodiment, the legs of the connecting spring may have a convex shape.

[0037] In other words, the two legs of the connection spring, together with the front part, may have a substantially elliptical or partially elliptical geometric shape, which starts from the front part and then widens initially, before gradually narrowing towards the opening (free end) of the connection spring.

[0038] In another embodiment, the connecting spring may be made of metal, in particular spring steel.

[0039] The object of the present invention is further solved by a protective housing system comprising a protective housing according to any one of the above aspects and a connection spring according to any one of the above aspects, wherein the connection spring surrounds the protective housing, the front part of the connection spring is fully or nearly fully receivable (received) in the circumferential protective housing groove, and the legs of the connection spring protrude beyond the protective housing in an untensioned (untensioned) state.

[0040] In other words, in the assembled state, the connection spring surrounds the protective housing in such a manner that the legs of the connection spring extend substantially parallel to the longitudinal direction (extension direction) of the protective housing. In the assembled state, the front part of the connection spring is received in the circumferential protective housing groove of the protective housing. Preferably, the front part of the connection spring is received in the circumferential protective housing groove of the protective housing in such a manner that it does not protrude beyond the geometric shape (contour) of the protective housing.

[0041] In one embodiment, the legs of the connecting spring may be at least partially receivable in a circumferential protective housing groove in the protective housing when in a tensioned state.

[0042] In other words, the legs of the connection spring may be arranged parallel to the protective housing groove in such a manner that they protrude into the protective housing groove of the protective housing when the connection spring is stretched (tensioned).

[0043] This configuration of the protective housing system ensures that the connection spring does not jam, pinch, or slip when the protective housing system is inserted into the medical product (the protective housing receiving portion of the medical product), and a form fit between the connection spring, the protective housing, and the medical product can be reliably achieved.

[0044] The object of the present invention is further achieved by a medical product system comprising a protective housing according to any one of the above aspects, a medical product according to any one of the above aspects, and a connection spring according to any one of the above aspects, wherein in an assembled state, the connection spring engages in a form-fitting manner with a circumferential protective housing groove of the protective housing and simultaneously engages in a form-fitting manner with a wall groove of the protective housing receiving part, thereby fixing the protective housing in the medical product.

[0045] In other words, in the assembled state, the connecting spring (particularly the front part) may engage in a form-fitting manner with the circumferential protective housing groove of the protective housing. In the assembled state, the legs of the connecting spring may engage at least with the wall grooves of the protective housing receiving part.

[0046] In one embodiment, the medical product may include a disassembly opening that connects the wall channel to the surrounding environment of the medical product system in an assembled state to allow tensioning of the connection spring.

[0047] In other words, the medical product may comprise a disassembly opening directly adjacent to the protective housing receiving portion. The disassembly opening is a hole (through-hole) that allows a special tool to be inserted into the wall groove. The special tool is used to press the legs of the connection spring into the protective housing groove by overcoming the spring force of the connection spring. This allows the form-fit between the connection spring, the wall groove and the protective housing groove to be released. The protective housing with the transponder held therein can then be non-destructively removed from the medical product.

[0048] The disassembly opening can be positioned in any orientation relative to the wall groove, as long as tension can be applied to the connection spring through the disassembly opening.

[0049] Preferably, the disassembly opening may be located on the top and / or bottom surface of the medical product and may extend perpendicularly from the top and / or bottom surface.

[0050] Alternatively or additionally, the disassembly opening may be provided on a side of the tool (preferably a surface essentially perpendicular to the upper and / or lower surfaces) or may extend parallel to the upper and / or lower surfaces.

[0051] In another embodiment, the medical product and / or protective housing may be constructed from a hard, inelastic material. [Brief explanation of the drawings]

[0053] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0054] FIG. 1 shows a tool (medical tool) 1 according to the present invention, which includes a protective housing receiving portion 3. In FIG. 1, the protective housing receiving portion 3 is shown enlarged. FIG. 2 shows the protective housing receiving portion 3 in a cross-sectional view taken along line AA of FIG. 1. The protective housing receiving portion 3 forms a substantially cylindrical recess within the tool 1. The base surface (negative extrusion) of the protective housing receiving portion 3 has a pill-like shape, with two parallel sections and two semicircular sections (radius sections) separating the parallel sections. However, other shapes are also possible, and the shape of the protective housing receiving portion 3 is adapted to the shape of the protective housing (see, for example, FIG. 6 ). The inner wall 5 of the protective housing receiving portion 3 has a wall groove 7. The wall groove 7 is located in the parallel section of the protective housing receiving portion 3 and terminates in the semicircular section (radius section) of the inner wall 5 of the protective housing receiving portion 3. However, it is also possible for the wall groove 7 to be located around the entire circumference of the inner wall 5 of the protective housing receiving portion 3. The wall groove 7 is provided as a substantially rectangular recess in the inner wall 5, extending away from the protective housing receiving portion 3. The wall groove 7 is oriented parallel to the tool surface 9 and is centrally located in the protective housing receiving portion 3 in the height direction Z.

[0055] In this embodiment, the protective housing receiving portion 3 is configured as a through opening in the tool 1. However, it is also conceivable that the protective housing receiving portion 3 is configured as a kind of blind hole.

[0056] FIG. 3 shows the protective housing receiving portion 3 in another cross-sectional view. In FIG. 3, the protective housing 11 is shown with a glass tag 13. The glass tag 13 is received (received) in a tag receiving portion 15 of the protective housing 11. The protective housing 11 is arranged in the protective housing receiving portion 3. The glass tag 13 is a radio-readable transponder element that allows at least one identification of the tool 1. Further, tool-related information may be stored in the glass tag 13. The glass tag 13 may be completely enclosed by the protective housing 11. Alternatively, the tag receiving portion 15 may be configured with an opening accessible from the outside, which opening allows the glass tag 13 to be inserted into the protective housing 11.

[0057] The tag receiving portion 15 extends in the longitudinal direction of the protective housing 11. The protective housing 11 also has a protective housing groove 17 provided circumferentially on the outer surface of the protective housing 11. The protective housing groove 17 is provided in the same plane as the central axis M of the tag receiving portion 15. The wall groove 7 of the protective housing receiving portion 3 and the protective housing groove 17 together form a groove space 19 in an assembled state. A spring (connecting spring) 21 is provided in the groove space 19 to fix the protective housing 11 in the protective housing receiving portion 3 in a form-fitting manner. The protective housing 11 and the protective housing receiving portion 3 are adapted to each other so that the protective housing 11 is substantially completely received in the protective housing receiving portion 3.

[0058] 4 shows a spring 21 having a substantially U-shaped geometry. The spring 21 is made of spring steel and is integrally formed. The spring 21 forms a clasp with two ovally shaped legs 23 that are open on one side. The legs 23 have spherical (semicircular) recesses 25 on their inner parts (inner edges) facing each other. The two legs 23 are connected to each other at a front part 27.

[0059] In the following, the assembly process of the protective housing 11 with the spring 21 in the protective housing receptacle 3 will be explained in more detail with reference to FIGS.

[0060] 5 shows the protective housing 11 and spring 21 in a pre-assembled state. In other words, the spring 21 is inserted into the protective housing groove 17 of the protective housing 11. The legs 23 of the spring 21 protrude beyond the basic pill-shaped shape of the protective housing 11, and the front part 27 of the spring 21 is fully received within the protective housing groove 17.

[0061] To secure the protective housing 11 including the glass tag 13 within the protective housing receptacle 3 of the tool 1, the legs 23 of the spring 21 are pushed together so that they are at least partially inserted into the protective housing groove 17, thereby tensioning the spring 21. The protective housing 11 with the tensioned spring 21 is pushed into the protective housing receptacle 3 by a user, and the inner wall 5 of the protective housing receptacle 3 holds the spring 21 in the tensioned state. When the protective housing 11 is placed in the predetermined position provided for it within the protective housing receptacle 3, i.e., when the protective housing groove 17 and the wall groove 7 of the protective housing receptacle 3 are arranged in the same plane, the spring 21 relaxes and the legs 23 of the spring 21 engage with the wall groove 7 of the protective housing receptacle 3. The spring 21 is thus received in both the wall groove 7 of the protective housing receptacle 3 and the protective housing groove 17, thereby connecting the protective housing 11 to the tool 1 in a form-fitting manner.

[0062] FIG. 7 shows a protective housing 11 with a spring 21 in a first alternative embodiment, where the protective housing 11 is mounted in the protective housing receiving portion 3. This embodiment substantially corresponds to the previously described embodiment. In addition, the first alternative embodiment includes two disassembly openings 29. In the first alternative embodiment, the disassembly openings 29 are configured as holes that perpendicularly intersect (penetrate) the wall grooves 7 of the protective housing receiving portion 3. The disassembly openings 29 enable the protective housing 11 to be removed from the protective housing receiving portion 3. Specifically, by using a special tool (not shown), the legs 23 of the spring 21 can be pushed together through the disassembly openings 29. This applies tension to the spring 21 so that the spring 21 disengages from the wall grooves 7 of the protective housing receiving portion 3. This allows the protective housing 11 to be removed from the protective housing receiving portion 3.

[0063] 8 shows a protective housing 11 with a spring 21 in a second alternative embodiment, which is mounted in the protective housing receptacle 3. This embodiment substantially corresponds to the first alternative embodiment. In contrast to the first alternative embodiment, the disassembly opening 29 is provided flush with the wall groove 7 and the protective housing groove 17.

[0064] The arrangement of the disassembly opening 29 is determined mainly by the shape of the tool 1 .

[0065] In the illustrated embodiment, the wall groove 7 is configured as a rectangular recess. Alternatively, the wall groove 7 may be configured as a rounded, spherical, or elliptical recess. In particular, if the wall groove 7 is configured as a rounded recess, the spring 21 may be made of rounded wire. When the wall groove 7 and the spring 21 are configured in this way, the release force of the groove-spring connection can be set by selecting the overlap between the spring 21 and the wall groove 7. If the release force is appropriately low, tool-free disassembly (removal) can be achieved. If the spring 21 and the wall groove 7 overlap completely, a non-removable connection, or a connection that cannot be removed without tools, can also be produced with this type of design.

[0066] In the illustrated embodiment, the protective housing groove 17 is coplanar with the central axis M of the tag receiving portion 15. However, alternative embodiments are contemplated in which the protective housing groove 17 is not coplanar with the central axis M of the tag receiving portion 15.

[0067] In the illustrated embodiment, the spring 21 (the legs 23 of the spring 21) is configured with spherical recesses 25. However, these recesses 25 are not necessarily required. If a suitable material is selected for the spring 21, the recesses 25 may be omitted. The recesses 25 may be used, among other things, to adjust the spring force of the spring 21.
