The first cavity is used to store water, and the second cavity is used to store coolant. A puncture assembly includes a housing and a puncture member disposed within the housing. The housing is disposed on the cooling wall, and the housing has an opening communicating with the interior of the housing on the side facing the separating membrane. The puncture member includes a puncture portion. The disposable medical finger amputation storage bag has a storage state and a use state. In the storage state, the puncture part is located inside the outer shell. In the use state, the puncture part extends out of the opening to puncture the separator membrane, so that the water in the first cavity and the coolant in the second cavity merge and absorb heat.

[0007] According to an embodiment of the present invention, the disposable medical finger amputation storage bag includes a puncture assembly that further includes a control component. The puncture component is a puncture wheel rotatably connected to the outer shell. The puncture portion is located on one side of the puncture component and is toothed. One end of the control component is connected to the puncture component, and the other end is located outside the bag body. The teeth rotate under the action of the control component and extend out of the opening to puncture the separator membrane.

[0008] According to the disposable medical finger amputation storage bag of this utility model embodiment, the puncture component further includes a pressing part connected to the puncture part; a sliding channel is provided inside the outer shell, one end of the sliding channel has the opening, and the other end has a pressing port; the puncture component is slidably disposed in the sliding channel, and the pressing part at least partially extends out of the pressing port.

[0009] According to the disposable medical finger amputation storage bag of this utility model embodiment, the puncture component further includes an elastic member, which is connected to the outer shell and the puncture member; the elastic force of the elastic member causes the puncture portion to be completely contained within the outer shell.

[0020] Reference Figures 1 to 6 The following are several embodiments of the disposable medical finger amputation storage bag of this utility model.

[0021] like Figures 1 to 6 As shown, the disposable medical finger amputation storage bag of this utility model embodiment includes a bag body 100 and a puncture component 200; the bag body 100 includes two oppositely arranged sides 110, and a storage space 130 is formed between the two sides 110; at least one side 110 is a cooling wall 300; the cooling wall 300 includes a first membrane 310, a second membrane 320 and a separating membrane 330, the first membrane 310 and the second membrane 320 are connected, and a cooling cavity 340 is formed between the first membrane 310 and the second membrane 320; the separating membrane 330 is disposed in the cooling cavity 340 to divide the cooling cavity 340 into a first cavity and a second cavity; The first chamber is used to store water, and the second chamber is used to store coolant. The puncture assembly 200 includes a housing 220 and a puncture member 210 disposed within the housing 220. The housing 220 is disposed on the cooling wall 300, and the side of the housing 220 facing the separating membrane 330 has an opening communicating with the interior of the housing 220. The puncture member 210 includes a puncture portion 211. The disposable medical severed finger storage bag has a storage state and a use state. In the storage state, the puncture portion 211 is located inside the housing 220. In the use state, the puncture portion 211 extends out of the opening to puncture the separating membrane 330, so that the water in the first chamber and the coolant in the second chamber merge and absorb heat.

[0022] In use, the puncture part 211 punctures the separator membrane 330, connecting the first and second chambers. This allows water and coolant to mix and rapidly absorb heat, thereby lowering the temperature of the cooling wall 300 to freeze the severed finger within the storage space 130, effectively delaying tissue cell necrosis and buying valuable time for replantation surgery. During storage, the separator membrane 330 isolates the cooling chamber 340 into two chambers, the first and second, allowing water and coolant to be stored separately. This ensures that water and coolant do not come into contact with each other during storage and transportation, thus ensuring stable separation during storage and transportation. In use, the puncture component 200 directly punctures the separator membrane 330, allowing the isolated water and coolant to come into instantaneous contact and fully mix, achieving an immediate cooling effect. The operation is simple and quick.

[0023] Generally, the coolant can be ammonium nitrate crystals or ammonium nitrate in both solid and liquid states. When ammonium nitrate dissolves in water, it undergoes a strong endothermic reaction, rapidly absorbing heat from the surrounding environment, thereby quickly and significantly reducing the temperature of the entire cooling wall 300. The cold energy generated by the reaction is transferred through the cooling wall 300 to the storage space 130 inside the bag, which in turn lowers the temperature of the storage space 130, creating a low-temperature environment for the severed finger. By creating and maintaining a low temperature for the severed finger, a constant storage environment of 2-8°C is formed, which effectively delays tissue cell necrosis and buys valuable time for replantation surgery.

[0024] This disposable medical finger amputation storage bag instantly activates cooling through a simple puncture operation, requiring no external power supply or pre-cooling equipment. It provides a low-temperature environment for the amputated finger immediately after an accident, significantly shortening the cooling time. The separator 330 strictly isolates water and coolant during storage and transportation, effectively preventing accidental mixing and resulting failure or leakage, ensuring the product is always usable. During storage, the puncture part 211 is housed within the outer shell 220, preventing it from accidentally puncturing the separator 330 during transport. The mixture of water and coolant (such as ammonium nitrate) undergoes a vigorous endothermic reaction, which occurs rapidly and quickly reaches the required low temperature, rapidly and significantly reducing the temperature inside the bag. Operation is simple and convenient; even non-professionals can easily operate it in emergencies to implement critical treatment. The continuously low-temperature environment effectively slows down the metabolism and necrosis of the amputated finger tissue cells, maximizing tissue viability and providing valuable time for subsequent replantation surgery, thus improving the replantation survival rate. This disposable medical finger amputation storage bag, as described in this embodiment, has a simple structure, low cost, and is disposable after single use, reducing cross-infection.

[0025] like Figures 4 to 6As shown, in some embodiments, the piercing assembly 200 further includes a control element 230. The piercing element 210 is a piercing wheel rotatably connected to the housing 220. The piercing portion 211 is located on one side of the piercing element 210 and has teeth. One end of the control element 230 is connected to the piercing element 210, and the other end is located outside the bag body 100. The teeth rotate under the action of the control element and extend out of the opening to pierce the separator membrane. Figure 5 This is a structural diagram of the puncture component 200 in use. Figure 6 This is a structural diagram of the puncture component 200 in its stored state.

[0026] Understandably, the user operates the control unit 230 to rotate the puncture wheel. In the stored state of the disposable medical finger amputation storage bag, the teeth of the puncture wheel face the bottom inside the outer shell 220, and the teeth are located inside the outer shell 220 to prevent the teeth from protruding outside the opening and accidentally puncturing the separator membrane 330. In the used state of the disposable medical finger amputation storage bag, the teeth protrude from the opening and puncture the separator membrane 330, allowing water and coolant to mix and absorb heat, thereby lowering the temperature of the storage space 130 and providing a stable low-temperature environment for the amputated finger within the storage space 130. One end of the control unit 230 is connected to the puncture component 210, and the other end is located outside the bag body 100, facilitating switching the used state of the disposable medical finger amputation storage bag via the control unit 230. It should be noted that the length of the teeth is greater than one-third of the circumference of the puncture wheel to ensure that the teeth can puncture the separator membrane 330. The control unit 230 can be a rotating shaft, which is rotatably connected to the first membrane 310 or the second membrane 320. One end of the control component 230 is connected to the puncture component 210. The user can rotate the control component 230 forward or backward to control the teeth to extend the opening, providing high flexibility and facilitating quick activation and switching of the disposable medical finger amputation storage bag in emergencies. Puncture components 200 can be provided on both sides of the separating membrane 330, with one puncture component 200 located in the first cavity and the other in the second cavity. In use, rotating the control component 230 causes the teeth of both puncture components 200 to face the separating membrane 330, puncturing the separating membrane 330 and connecting the first and second cavities. The first membrane 310 or the second membrane 320 is fitted tightly against the outer shell 220, allowing one end of the control component 230 to be positioned outside the bag body 100.

[0027] like Figures 2 to 3As shown, in some embodiments, the piercing member 210 further includes a pressing part 212 connected to the piercing part 211; a sliding channel 221 is provided inside the housing 220, one end of the sliding channel 221 has an opening, and the other end has a pressing port; the piercing member 210 is slidably disposed in the sliding channel 221, and the pressing part 212 at least partially extends out of the pressing port; by pressing the pressing part 212 through the pressing port, the piercing member 210 slides within the sliding channel 221, causing the piercing part 211 to extend out of the opening to pierce the separating membrane 330; the sliding channel 221 can guide the movement path of the piercing member 210, so that the piercing part 211 can quickly and accurately pierce the separating membrane 330. The pressing part 212 at least partially extends out of the pressing port for easy pressing. Figure 3 This is a structural diagram of the puncture component 200 in use.

[0028] like Figures 1 to 3 As shown, in some embodiments, the piercing assembly 200 further includes an elastic element 240, which is connected to the housing 220 and the piercing element 210. The elastic force of the elastic element 240 ensures that the piercing part 211 is completely contained within the housing 220, preventing the piercing part 211 from being vibrated during transportation and protruding from the opening, thus preventing premature puncture of the separator membrane 330 and its failure. After use, the elastic force of the elastic element 240 causes the piercing part 211 to move in the opposite direction of the piercing direction, completely retracting the sharp piercing part 211 into the housing 220, thereby safely containing the piercing element 210 within the housing 220 without manual operation, achieving rapid and reliable return of the piercing element 210 and preventing accidental scratches to the user by the piercing part 211, thus avoiding secondary injury. Generally, the elastic element 240 is a spring. Figure 2 This is a structural diagram of the puncture component 200 in its stored state.

[0029] like Figures 1 to 3 As shown, in some embodiments, the sliding channel 221 has a limiting protrusion 222 at one end near the opening, the pressing part 212 has a stepped surface on the side facing the opening, and the elastic member 240 is disposed in the sliding channel 221, with one end of the elastic member 240 connected to the limiting protrusion 222 and the other end connected to the stepped surface; when the pressing part 212 is pressed through the pressing port, the piercing member 210 slides in the sliding channel 221, and the piercing part 211 pierces the separating membrane 330. At this time, the elastic member 240 is compressed and stores energy; when the pressing part 212 is released, the elastic member 240 releases elastic potential energy, and the piercing part 211 moves in the opposite direction of the piercing direction and retracts into the sliding channel 221.

[0030] like Figure 1As shown, in some embodiments, both sides 110 are cooling walls 300. The two cooling walls 300 work together to absorb heat and cool down, making the temperature of the storage space 130 more uniform, improving the cooling efficiency, and avoiding the problem of uneven cooling effect or insufficient local cooling that may be caused by unilateral cooling, thereby ensuring the preservation effect of the severed finger tissue.

[0031] like Figure 1 As shown, in some embodiments, the bag body 100 also includes a bottom 120, which connects to two sides 110. The bottom 120 can provide support for the severed finger from below the bag body 100, reducing the shaking of the severed finger during transportation and avoiding secondary damage to the severed finger. The bottom 120 is a cooling wall 300. Since the severed finger naturally sinks to the bottom in the storage space 130, the surface of the severed finger is in close contact with the cooling wall 300 of the bottom 120, achieving efficient heat absorption to achieve the cooling environment required for the storage of the severed finger, thereby enhancing the cooling efficiency and temperature uniformity of the disposable medical severed finger storage bag.

[0032] like Figures 1 to 3 As shown, in some embodiments, the puncture component 200 is provided on both sides of the separator membrane 330, allowing puncture to be performed from either side of the bag body 100. This facilitates rapid cooling of the disposable medical finger amputation storage bag, enabling users to quickly preserve the amputated finger in emergencies, thus gaining valuable time for subsequent replantation surgery and improving the replantation survival rate. A protective membrane can be provided on the outside of the bag body 100, with the first membrane 310 located outside the second membrane 320. The puncture component 200 can be fixed to the protective membrane and positioned between the protective membrane and the first membrane 310. In use, the puncture part 211 punctures the first membrane 310 and the separator membrane 330 in sequence, connecting the first cavity and the second cavity. This arrangement isolates the puncture component 200 from the first cavity, preventing corrosion and failure of the puncture component 200 due to prolonged immersion in water.

[0033] like Figure 1 As shown, in some embodiments, the bag body 100 is provided with an access port 140 communicating with the storage space 130, and the access port 140 is equipped with a zipper. Because the access port 140 of the storage space 130 is equipped with a zipper, the severed finger can be quickly accessed and placed, and a reliable seal is obtained when the severed finger is stored. The user pulls the zipper to quickly open and close the access port 140. When the zipper is opened, the severed finger can be put in or taken out without obstruction, and when the zipper is closed, a physical seal is formed by the tight engagement of the zipper teeth. This not only meets the need for rapid storage and retrieval of severed fingers in emergency situations where every second counts, but also effectively prevents external contaminants from entering the storage space 130, preventing the severed finger stored in the storage space 130 from being contaminated. At the same time, it prevents the internal cold air from escaping, maintains a stable low-temperature storage environment, and allows the severed finger to be effectively stored, thereby improving the survival rate of replantation.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
