[0037] In the above embodiment, as shown in Figure 1 The main body of the severed finger storage device is composed of a tank body 100 and a cover body 200, the cover body 200 is detachably arranged on the tank body 100, and is used for closing the open part in the tank body 100 to ensure the storage state of the severed finger in the tank body 100.

[0038] Specifically, as shown in Figure 2 The inside of the tank body 100 is provided with a refrigeration cavity 101 and a placing cavity 102, wherein the refrigeration cavity 101 is used for pouring low-temperature liquid to cool the air in the placing cavity 102 through temperature conduction, the placing cavity 102 is sleeved in the inside of the refrigeration cavity 101, and the placing cavity 102 is used for placing the severed finger in actual use, in this embodiment, when the severed finger is placed in the placing cavity 102, the low-temperature liquid in the refrigeration cavity 101 is poured to wrap the predetermined part of the placing cavity 102, and the placing cavity 102 can be stably kept in a certain temperature range within a certain time under the action of temperature conduction, thereby realizing the storage of the severed finger.

[0039] Further, in order to facilitate medical staff to conveniently observe the state of the severed finger during the transportation of the severed finger, and to determine whether the storage of the severed finger is effective, whether the low-temperature liquid needs to be replaced and the like in real time, in this embodiment, observation parts 110 are arranged on opposite sides of the tank body 100, as shown in Figure 1 and Figure 3 The cross-sectional shape of the observation part 110 is oval, and the observation part 110 is made of transparent material, specifically, can be made of transparent plastic, transparent glass and the like, since the cross-sectional shape of the observation part 110 is oval, the transmission effect of a convex lens can be formed, when the medical staff observes the tank body 100, the surface of the severed finger in the placing cavity 102 can be enlarged, thereby facilitating the medical staff to observe the detail condition change of the surface of the severed finger and deduce the storage state.

[0040] Based on the above embodiment, in one embodiment of the present application, as shown in Figure 1 and Figure 2 The tank body 100 includes shells 120 symmetrically arranged at both ends of the two observation parts 110, that is, the shells 120 are arranged on the left and right sides of the tank body 100, the shells 120 are used for protecting other parts of the tank body 100 and forming the containing vessel of the refrigeration cavity 101; at the same time, the tank body 100 also includes temperature guide walls 130 symmetrically arranged at both ends of the two observation parts 110, that is, the temperature guide walls 130 are also arranged on the left and right sides of the tank body 100 and are located on the inside of the corresponding shells 120; as shown in Figure 3As shown in the figure, the shell 120 is arranged along a first predetermined arc, and the space between the shell 120 and the temperature-conducting wall 130 forms the refrigeration cavity 101; the temperature-conducting wall 130 is arranged along a second predetermined arc, and the space between the temperature-conducting wall 130 and the observation part 110 forms the placement cavity 102. When the low-temperature liquid is poured into the refrigeration cavity 101, the placement cavity 102 corresponding to the temperature-conducting wall 130 is wrapped, and the temperature of the low-temperature liquid is conducted to the placement cavity 102, so that the air in the placement cavity 102 is cooled, and the severed finger is not in contact with the low-temperature liquid, thereby meeting the low-temperature and dry storage requirements of the severed finger.

[0041] Further, as shown in the figure, Figure 2 The shell 120 further comprises a first bottom plate 123, which is an extension of the shell 120, is tightly connected with the two ends of the shell 120, and is bent at a certain angle to form the bottom of the tank 100. Meanwhile, the two sides of the first bottom plate 123 are tightly connected with the two observation parts 110. Correspondingly, the temperature-conducting wall 130 further comprises a second bottom plate 131, which is an extension of the temperature-conducting wall 130, is tightly connected with the two ends of the temperature-conducting wall 130, and is bent at a certain angle to form the bottom of the placement cavity. Meanwhile, the two sides of the second bottom plate 131 are tightly connected with the side walls of the two observation parts 110. Through the above arrangement, the first bottom plate 123 and the second bottom plate 131 together with the side walls of the observation parts 110 form a channel structure, which connects the refrigeration cavities 101 on both sides of the placement cavity 102. According to the principle of the communicating vessels, when the low-temperature liquid is poured into one side of the refrigeration cavity 101, the low-temperature liquid can be poured to the same height on the other side, thereby ensuring that the low-temperature liquid in the refrigeration cavity 101 uniformly conducts the temperature to the placement cavity 102.

[0042] In the above embodiment, as shown in the figure, Figure 2As shown, the shell 120 is specifically composed of a protective layer 121 and a heat preservation layer 122, wherein the protective layer 121 is made of metal or other anti-collision materials and is used for protecting the tank body 100, and the inner side of the shell 120 is attached with the heat preservation layer 122 on the side facing the refrigeration cavity 101, and the heat preservation layer 122 is specifically made of polyurethane foam plastic or other materials with low thermal conductivity, only 0.022-0.033 W / (m*K), so as to realize the heat preservation effect of the inner side of the shell 120. Correspondingly, the temperature-conducting wall 130 should be made of materials easy to conduct temperature, such as aluminum, temperature-conducting polymer, ceramic material, etc., and at the same time, the selection of the above-mentioned materials should also consider the connection strength with the observation part 110, so as to avoid the situation that the low-temperature liquid contacts the severed finger due to liquid leakage. The embodiment sets the temperature-conducting wall 130 easy to conduct temperature, so that the low-temperature liquid in the refrigeration cavity 101 can quickly conduct low temperature to the placing cavity 102, thereby forming a storage environment suitable for placing the severed finger and maintaining a suitable storage state within a certain time, and when the low-temperature liquid in the refrigeration cavity 101 needs to be replaced, the operation process will not affect the severed finger, and the severed finger can be effectively preserved.

[0043] In another embodiment of the present application, as shown in Figure 1 and Figure 2 As shown, the tank body 100 further comprises a top plate 300, which is in close connection with the upper end of the shell 120, the temperature-conducting wall 130 and the observation part 110, and the position corresponding to the placing cavity 102 on the top plate 300 is open, and the remaining parts are sealed, so that the refrigeration cavity 101 forms a closable cavity, and the cover 200 is detachably arranged on the top plate 300 to close the position corresponding to the placing cavity 102 on the top plate 300, thereby preventing the severed finger from falling out after being placed.

[0044] In order to realize the combination of the top plate 300 and the cover 200, a connecting ring 310 is further arranged on the side of the top plate 300 away from the placing cavity 102 in the embodiment, the connecting ring 310 is arranged protruding from the side surface of the top plate 300, and a screw thread is arranged on the outer side of the connecting ring 310, and correspondingly, a connecting groove is further arranged on one side of the cover 200, and a screw thread adapted to the connecting ring 310 is arranged on the inner side of the connecting groove, by buckling the cover 200 on the connecting ring 310 and rotating in a predetermined direction, the cover 200 can be combined with the top plate 300 firmly to realize the effect of closing the placing cavity 102.

[0045] In the embodiment, the cover 200 or the inside of the cover 200 is made of a heat preservation material, such as the polyurethane foam mentioned above, and the connecting ring 310 is preferably integrally formed with the top plate 300. When the cover 200 is combined with the connecting ring 310, the cover 200 not only forms a closed upper end of the storage cavity 102, but also has a heat preservation effect, thereby prolonging the heat preservation time of the severed finger storage device.

[0046] Further, when the heat conducting ring is arranged, it should correspond to the open part of the upper end of the storage cavity 102. In some specific embodiments, the inner hole size of the heat conducting ring may not correspond to the inner size of the open part of the upper end of the storage cavity 102, for example, the inner hole size of the heat conducting ring is larger than the inner hole size of the upper end of the storage cavity 102, so as to constrain the placement position of the severed finger in the storage cavity 102; or the inner hole size of the heat conducting ring is smaller than the inner hole size of the upper end of the storage cavity 102, so as to place multiple severed fingers in the storage cavity 102 at the same time. For the above-mentioned cases, the position corresponding to the connecting ring 310 of the storage cavity 102 is smoothly transitioned, so as to avoid damaging the severed finger when placing or taking out the severed finger.

[0047] Further, as shown in Figure 1 and Figure 2 , in order to facilitate the medical staff to pour the low-temperature liquid into the refrigeration cavity 101, a pouring port 320 is arranged on one side of the cover 200 in the embodiment. The pouring port 320 is a through hole structure penetrating through the cover 200, which is used to facilitate the medical staff to pour the low-temperature liquid into the refrigeration cavity 101. In the embodiment, in order to prevent the low-temperature liquid from leaking from the pouring port 320, a rubber plug 321 is arranged on the top plate 300 in the embodiment. The rubber plug 321 can be detachably sleeved in the pouring port 320, and the rubber plug 321 can realize the sealing effect of the refrigeration cavity 101. When the cover 200 is buckled on the tank body 100, the cover 200 presses the rubber plug 321, thereby further fixing the rubber plug 321, so as to effectively avoid the low-temperature liquid flowing out along the pouring port 320 due to the bumping during transportation.

[0048] In the embodiment, as shown in Figure 1 , in order to avoid the influence of the medical staff replacing the low-temperature liquid on the severed finger, a suitable sealing plug 311 is arranged on the connecting ring 310. The sealing plug 311 is also made of rubber material, which is used to sleeve and close the inner hole of the connecting ring 310. Therefore, when the medical staff replaces the low-temperature liquid, the tank body 100 can be tilted to pour or pour the low-temperature liquid. During the process, since the storage cavity 102 is closed by the sealing plug 311, the temperature in the storage cavity 102 will not change suddenly, or the severed finger will not slide out of the storage cavity 102.

[0049] In the above embodiment, in order to avoid heat exchange between the observation section 110 and the outside, which would result in poor heat preservation of the severed finger storage device, a heat insulation layer is provided on the side of the observation section 110 facing the cooling chamber 101 and the placement chamber 102, respectively. The heat insulation layer should be a transparent heat insulation layer and should not affect the optical effect of the observation section 110, such as a nano transparent heat insulation coating, etc. In this way, together with the heat insulation layer 122 in the outer shell 120 and the heat insulation cover 200, a full-range wrapping of the placement chamber 102 and the cooling chamber 101 can be formed to ensure the effective duration of the cryogenic liquid.

[0050] In the above embodiments, the cryogenic liquid can be made of various materials depending on the transport time of the severed finger. For example, by utilizing the heat absorption effect of inorganic ammonium salts dissolved in water, inorganic ammonium salts (ammonium nitrate salts, ammonium chloride salts) can be pre-placed in the cooling chamber 101. When in use, water is poured into the cooling chamber 101 to form a cooling effect similar to an artificial ice pack, so that the severed finger storage device provided by this utility model can be used quickly and conveniently.

[0051] Based on the above embodiments, the actual use of this new finger-severing storage device is as follows:

[0052] First, prepare a device for storing severed fingers in advance, and place inorganic ammonium salts in the cooling chamber 101 in advance;

[0053] When a severed finger needs to be transferred, such as Figure 1 As shown, separate the cover 200 from the tank 100, remove the sealing plug 311 on the connecting ring 310, place the patient's severed finger into the placement cavity 102, fasten the sealing plug 311, then open the rubber stopper 321, pour water into the cooling cavity 101, and fasten the rubber stopper 321. Figure 4 As shown, the lid 200 is then combined with the tank 100. Due to the large amount of heat absorbed by the reaction of inorganic ammonium salt with water, the temperature inside the placement chamber 102 can be quickly cooled to the predetermined temperature range to create a suitable storage environment for severed fingers.

[0054] During transportation, medical staff can observe the magnified image of the surface of the severed finger through the observation unit 110 to determine the preservation status of the severed finger. When long-distance transportation is required, the refrigerant in the cooling chamber 101 can be replaced during the process without affecting the preservation of the severed finger, which can effectively protect the severed finger. At the same time, since the cooling is based on a physical reaction and is not limited by electrical energy factors, it can avoid the situation where the severed finger cannot be preserved due to damage to the power supply device.

[0055] In addition, to ensure more secure preservation during the transport of severed fingers, it can be used in conjunction with existing refrigeration boxes. During transport, medical staff can directly remove the storage device for the severed finger and observe it through the observation unit 110, thus facilitating real-time monitoring of the finger's condition.

[0056] Based on the above-mentioned embodiments, the utility model still provides a kind of sample container, the sample container includes the severed finger storage instrument described in any one of the above-mentioned embodiments, the severed finger storage instrument includes: jar body, refrigeration cavity is provided inside jar body, placing cavity is set in the inboard of refrigeration cavity, corresponding placing cavity's opposite sides of jar body are provided with observation part respectively, the cross-sectional shape of observation part is oval, and observation part is transparent observation part;Cover body, the upper end of jar body is open and set at the position corresponding to placing cavity, and cover body is detachably connected with the upper end of jar body.The utility model is by being provided with refrigeration cavity inside jar body, and placing cavity is set in the inboard of refrigeration cavity, and the observation part of transparent, cross section oval is set in the two sides of placing cavity, and observation part forms convex lens, and in use, the preservation of severed finger in placing cavity is formed by pouring low-temperature liquid into refrigeration cavity, and medical staff can observe the condition of severed finger by the magnifying function of observation part without opening cover body, it is convenient to observe severed finger and adjust the state of preservation, reduce the probability of the failure of replantation caused by the poor state of preservation of severed finger in the process of transportation.
