Description

Technical Field

[0001] This utility model relates to the field of storage container technology, specifically to a container for convenient storage and recycling of guidewires used in cardiac angiography stent surgery. Background Technology

[0002] In cardiac surgery, guidewires, sheaths, and stents are among the most common instruments. A guidewire is a thin, long wire made of precious metal. Its function is to first enter the blood vessel during stent placement. Utilizing the highly malleable tip of the guidewire, it is inserted into the correct blood vessel, thereby guiding the subsequent sheath and stent along the guidewire to their designated positions.

[0003] Due to current manufacturing processes, most guidewires contain precious metals such as nickel-titanium alloys and platinum. Therefore, the safety of guidewire recycling and storage is paramount. Firstly, their sharp and thin nature makes them prone to puncturing packaging and contamination during transportation. Secondly, their high precious metal content makes them susceptible to loss during recycling. Finally, current technology often involves directly stuffing guidewires into recycling bags, leading to tangling and knotting. To ensure better guidewire recycling, the guidewires must be straightened before the post-recycling cleaning process begins to guarantee effective cleaning and prepare for subsequent sorting. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the guide wire in the prior art that it is easy to be contaminated and easily tangled during transportation and recycling, thereby providing a medical guide wire storage container.

[0005] This utility model provides a medical guidewire storage container, which includes:

[0006] A pull-out box has a guide post inside, a guide wire is wound on the guide post, and the side of the pull-out box has a guide wire inlet;

[0007] A guide wheel is rotatably disposed inside the guide wire inlet;

[0008] The casing is movable and engages with the pull-out box.

[0009] Preferably, the pull-out box has a middle base plate, and the edges of the middle base plate are sequentially connected to an outlet curved wall, a first straight wall, a first curved wall, a second straight wall, and a second curved wall; the guide wire inlet is formed between the outlet curved wall and the second curved wall.

[0010] Preferably, the housing has an upper base plate, a supporting outer wall, and a lower base plate, with the upper and lower sides of the supporting outer wall respectively connected to the upper base plate and the lower base plate, and notches formed at both ends of the supporting outer wall;

[0011] When in the assembled state, the casing and pull-out box are stacked, and the notch is positioned for the placement of the second curved wall and guide wire inlet.

[0012] Preferably, the upper base plate has a first positioning protrusion in the middle, and the top of the guide post has a positioning groove, with the first positioning protrusion cooperating with the positioning groove.

[0013] Preferably, the upper base plate also has a second positioning protrusion, which is used to cooperate with the positioning groove.

[0014] Preferably, the upper base plate has an upper limit portion, and the lower base plate also has a lower limit portion;

[0015] When in the assembled state, the first straight wall, the first curved wall, the second straight wall and the upper limit position are arranged adjacent to each other and cooperate with each other.

[0016] Preferably, the second curved wall has a mounting hole inside the guide wire inlet, a fixed shaft is provided in the mounting hole, and the guide wheel is rotatably mounted on the fixed shaft.

[0017] Preferably, a portion of the guide wheel is located in the outer space of the second curved wall.

[0018] Preferably, the outer side of the second curved wall has a handle.

[0019] Preferably, the guide wheel is a flexible roller.

[0020] The technical solution of this utility model has the following advantages:

[0021] 1. The medical guidewire storage container provided by this utility model allows one end of the used guidewire to pass through the guidewire inlet, enter the pull-out box along the guide wheel, and gradually coil around the guide post, thus straightening the guidewire during retrieval. Simultaneously, the casing provides a sealed storage function, improving storage safety. The casing prevents the guidewire from being punctured during both pre-use transportation and post-use retrieval. Furthermore, the pull-out design of the casing facilitates opening and closing the pull-out box, making it convenient to remove the guidewire all at once during later collection and retrieval.

[0022] 2. The storage container provided by this utility model can simultaneously fulfill the dual functions of guidewire packaging at the factory and recycling after use. After attaching product information to the storage container, the used guidewires can be recycled using the same container, making guidewire recycling management more convenient and preventing guidewire loss after use.

[0023] 3. The combination design of the shell and the pull-out box facilitates the separation of the shell and the pull-out box. The two form a pull-out structure, that is, the shell fits and cooperates with the first straight wall and the second straight wall. Then, the shell is separated from the pull-out box by pulling each other to expose the internal guide post for one-time removal of the guide wire.

[0024] 4. In the assembled state, the first positioning protrusion engages with the positioning groove for positioning. When the shell is pulled, it gradually separates from the pull-out box. At this time, the first positioning protrusion loses its engagement with the positioning groove. After moving a certain distance, the second positioning protrusion engages with the positioning groove again for positioning. At this time, a portion of the internal space of the pull-out box is exposed. When needed, the engagement of the second positioning protrusion with the positioning groove can be overcome again to completely separate the shell from the pull-out box. Attached Figure Description

Detailed Implementation

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, the present invention provides a medical guidewire storage container, which includes:

[0037] The pull-out box 10 has a guide post 11 inside, on which a guide wire 12 is wound. The side of the pull-out box 10 has a guide wire inlet 13. A guide wheel 20 is rotatably disposed inside the guide wire inlet 13. A cover 30 has an overall shape similar to a drawer cover and is used for pulling out the pull-out box 10.

[0038] In this embodiment, the medical guidewire storage container allows one end of the used guidewire 12 to pass through the guidewire inlet 13, enter the pull-out box 10 along the guide wheel 20, and gradually coil around the guide post 11. The casing 30 thus provides a sealed storage function, improving storage safety. Furthermore, the movable design of the casing 30, allowing it to move relative to the pull-out box 10, facilitates opening and closing the box, making it easier to remove the guidewire 12 from the box 10 in one go during later collection and retrieval.

[0039] In this embodiment, the pull-out box 10 has a middle base plate 16, and the edge of the middle base plate 16 is sequentially connected to an outlet curved wall 161, a first straight wall 162, a first curved wall 163, a second straight wall 164, and a second curved wall 165; the guide wire inlet 13 is formed between the outlet curved wall 161 and the second curved wall 165.

[0040] Combination Figure 6As shown, the casing 30 has an upper base plate 31, a supporting outer wall 32, and a lower base plate 33. The upper and lower sides of the supporting outer wall 32 are respectively connected to the upper base plate 31 and the lower base plate 33, and notches 331 are formed at both ends of the supporting outer wall 32. It should be noted that, in Figure 4 For ease of observation, the casing 30 is divided into an upper base plate 31 and a lower base plate 33 for display. However, in reality, the upper base plate 31 and the lower base plate 33 are connected together by the supporting outer wall 32, forming a one-piece structure. The casing 30, as a whole, can move relative to the pull-out box 10.

[0041] When in the assembled state, the housing 30 is fitted over the pull-out box 10, and the notch 331 is positioned for the placement of the second curved wall 165 and the guide wire inlet 13.

[0042] The combination design of the housing 30 and the pull-out box 10 facilitates the separation of the housing 30 and the pull-out box 10. The two form a pull-out structure, that is, the housing 30 fits and cooperates with the first straight wall 162 and the second straight wall 164. Then, the housing 30 is separated from the pull-out box 10 by mutual pulling, so as to expose the internal guide post 11 for placing the guide wire 12.

[0043] Preferably, the upper base plate 31 has a first positioning protrusion 34 in the middle, and the top of the guide post 11 has a positioning groove 17, with the first positioning protrusion 34 engaging with the positioning groove 17. The upper base plate 31 also has a second positioning protrusion 35, which engages with the positioning groove 17. In the assembled state, the first positioning protrusion 24 engages with the positioning groove 17 for locking and positioning. When the sleeve 30 is pulled, it gradually separates from the pull-out box 10. At this time, the first positioning protrusion 24 loses its engagement with the positioning groove 17. After moving a certain distance, it engages with the positioning groove 17 again through the second positioning protrusion 35, thus exposing a portion of the internal space of the pull-out box 10. When needed, the engagement of the second positioning protrusion 35 with the positioning groove 17 can be overcome again to completely separate the sleeve 30 from the pull-out box 10.

[0044] Preferably, the upper base plate 31 has an upper limit portion 36, and the lower base plate 33 also has a lower limit portion 18;

[0045] When assembled, the first straight wall 162, the first curved wall 163, and the second straight wall 164 are arranged adjacent to and cooperate with the upper limit part 36. This arrangement ensures that when the housing 30 moves relative to the pull-out box 10, the cooperation between the upper limit part 36 and the first straight wall 162 and the second straight wall 164 provides linear guidance, preventing deviation from the desired position during movement.

[0046] Preferably, the second curved wall 165 has a mounting hole 19 inside the guide wire inlet 13, a fixed shaft 191 is provided in the mounting hole 19, and the guide wheel 20 is rotatably mounted on the fixed shaft 191.

[0047] Preferably, a portion of the guide wheel 20 is located in the outer space of the second curved wall 165.

[0048] Preferably, the outer side of the second curved wall 165 has a handle 166, and when the housing 30 moves, one hand holds the handle 166 while the other hand drives the housing 30 to move.

[0049] Preferably, the guide wheel 20 has a rigid inner core for cooperating with the fixed shaft 191, and a flexible material is sleeved on the outside of the rigid inner core for cooperating with the guide wire, which improves the friction while avoiding damage to the guide wire.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
