Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and in particular to a sterile sealing cover structure used in a lung transplant ice maker. Background Art
[0002] Experimental research on lung transplantation can be traced back to the early 20th century. Human lung transplantation began in 1963. However, the longest survival time of nearly 40 patients who underwent surgery from 1963 to 1983 did not exceed 10 months. With the advent of cyclosporine A and the advancement of transplantation technology in the 1970s, Stanford University Hospital in the United States first achieved success in combined heart-lung transplantation in 1981; in 1983 and 1986, the Toronto Lung Transplant Group in Canada successfully performed single lung transplantation and double lung transplantation, ushering in a new era of lung transplantation. Since then, lung transplantation has developed rapidly. By 1997, the number of surgeries had reached 6,639, with a 3-year survival rate of more than 50% and a 5-year survival rate of more than 40%. After lung transplantation, patients have a good quality of life and can resume normal life. Some have already engaged in their previous work. Lung transplantation has become the only effective method for treating terminal lung disease.
[0003] With the gradual maturity of lung transplantation technology, donor preservation and perioperative management, the one-year survival rate of lung transplantation has increased from 70% in the past to 85%. Lung transplantation requires low-temperature preservation of organs from the beginning of organ acquisition, in order to reduce organ metabolism, oxygen consumption, and the production of oxygen free radicals, so that the organs can function better after transplantation. In lung transplantation, medical staff will pay attention to all aspects of organ protection, from organ acquisition to transplantation surgery to open perfusion, etc. During the implementation of the lung transplantation operation, the donor lung tissue is taken out of the low-temperature refrigerator and placed in the patient's chest cavity. Since the patient's body temperature will be maintained at a constant level of about 37°C after anesthesia, the donor lung will quickly heat up after contact with the patient, and the cell metabolism will be further accelerated. Due to the lack of blood supply, that is, the supply of nutrients, the cells will quickly become necrotic. If it is continuously maintained at 37°C without treatment, the function of the donor lung tissue after transplantation will be greatly reduced, so it needs to be continuously cooled during the lung transplantation process.
[0004] At present, most of the cooling methods used by medical staff during lung transplantation are to spread ice chips around the donor lungs. The ice chips are made by an ice maker. When making ice chips, medical staff need to put a refrigerant, such as alcohol, into the cooling tank of the ice maker, and then place a sterile ice basin on the cooling tank, and then inject sterile saline into the sterile ice basin. The sterile saline is slowly cooled by the refrigerant and finally forms ice. When medical staff need to spread ice chips around the donor lungs, they only need to use a sterile ice shovel to shovel on the ice formed by the sterile saline, and then spread the ice chips shoveled from the ice formed by the sterile saline around the donor lungs. During this process, the sterile ice basin is open and in contact with the external environment for a long time. The ice formed by cooling the sterile saline is very easy to be contaminated, which increases the probability of contamination of the ice formed by cooling the sterile saline, and brings great inconvenience to the lung transplantation work of medical staff. Summary of the invention
[0005] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a device with reasonable design, simple structure and easy operation. When medical staff need to spread ice chips around the donor lung, they only need to gently open the sterile cover body sealed on the sterile ice-making basin by hand, and then use a sterile ice shovel to shovel on the ice body formed by sterile saline, and spread the ice chips shoveled from the ice body formed by sterile saline on the periphery of the donor lung. Then the medical staff manually tears off a layer of sterile covering film close to the sterile ice-making basin from the observation hole, and casually seals the sterile cover body on the sterile refrigeration basin again, so that the ice formed by sterile saline in the sterile ice-making basin is in a sealed state at other times besides use, and reduces the contact time with the external environment, effectively reducing the probability of ice formed by cooling sterile saline being contaminated, and bringing great convenience to the lung transplantation work of medical staff.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.
[0020] Reference Figure 1-Figure 3 As shown in the figure, a sterile cover structure applied to a lung transplant ice maker includes a sterile cover towel 100 and a sterile cover body 200.
[0021] The sterile cover 100 is spread on the upper end surface of the lung transplant ice maker 300, and a clearance hole 110 corresponding to the cooling groove of the lung transplant ice maker 300 is opened in the middle of the sterile cover 100. This structure can further improve the practical performance of the sterile sealing structure.
[0022] The sterile cover body 200 is sealed around the sterile refrigeration basin. The sterile cover body 200 is arranged on the sterile cover towel 100 and is located at the position of the give way hole 110. One side of the sterile cover body 200 is hinged on the sterile cover towel 100. An observation hole 210 for observing the freezing condition of sterile saline in the sterile ice-making basin is opened in the middle of the sterile cover body 200. A multi-layer sterile sealing film 600 made of transparent soft plastic is arranged along the axial direction of the observation hole 210. The sterile sealing film 600 is sealed on the sterile ice-making basin.
[0023] A first anti-spray gasket 400 is provided at the lower end of the sterile cover 100 and around the make way hole 110 to prevent the refrigerant medium from spraying out from between the sterile cover and the cooling groove when medical staff are shoveling ice. The first anti-spray gasket 400 can effectively prevent the refrigerant medium from spraying out from between the sterile cover and the cooling groove, thereby effectively improving the practical performance of the sterile covering structure.
[0024] A second anti-spray gasket 500 is provided at the upper end of the sterile cover towel 100 and around the make way hole 110 to prevent the refrigerant medium from spraying out from between the sterile ice-making basin and the cooling groove when medical staff are shoveling ice. The second anti-spray gasket 500 can effectively prevent the refrigerant medium from spraying out from between the sterile ice-making basin and the cooling groove, further improving the practical performance of the sterile covering structure.
[0025] The first blowout preventer gasket 400 and the second blowout preventer gasket 500 are both made of flexible materials with good water absorption performance. In addition to being able to effectively prevent the refrigerant medium from spraying out from between the sterile ice basin and the cooling trough and between the sterile cover towel and the cooling trough, the first blowout preventer gasket 400 and the second blowout preventer gasket 500 made of such materials can also effectively reduce the vibration feeling of the sterile ice basin during the ice shoveling process by medical staff, further improving the stability performance between the sterile ice basin and the ice maker.
[0026] A handle 220 is provided on the other side of the sterile cover 200 for medical staff to open or close the sterile cover. This structure enables medical staff to open and close the sterile cover 200 more conveniently, further improving the practical performance of the sterile cover structure.
[0027] The specific operation of the present invention is as follows:
[0028] When the medical staff needs to cool down the donor lung during the lung transplantation, the medical staff only needs to gently hold the handle 220, then open the sterile cover 200 covering the sterile ice basin, and then use a sterile ice shovel to shovel the ice formed by the sterile saline solution, and spread the ice chips shoveled from the ice formed by the sterile saline solution around the donor lung. After the spreading is completed, the medical staff manually tears off a layer of sterile cover film 600 near the sterile ice basin from the observation hole 210. Then, hold the handle 220 by hand to slowly cover the sterile cover body 200 on the periphery of the sterile ice-making basin, and at the same time, cover the sterile cover film 600 on the sterile refrigeration basin. The cooling treatment of the donor lung is completed once. When the donor lung is cooled down for the next time, the specific operation is as above until the last layer of the sterile cover film 600 is torn off. The sterile cover film can be conveniently covered on the sterile ice-making basin under the gravity of the sterile cover body, and the sealing performance between the sterile cover film and the sterile ice-making basin is good.
[0029] In summary, the present invention adopts the above-mentioned structure. When medical staff need to spread ice chips around the donor lung, they only need to gently open the sterile cover sealed on the sterile ice basin by hand, and then use a sterile ice shovel to shovel the ice body formed by sterile saline, and spread the ice chips shoveled from the ice body formed by sterile saline on the periphery of the donor lung. Then the medical staff manually tears off a layer of sterile sealing film close to the sterile ice basin from the observation hole, and casually seals the sterile cover on the sterile refrigeration basin again. This can keep the ice formed by sterile saline in the sterile ice basin in a sealed state at other times besides use, and reduce the contact time with the external environment, effectively reducing the probability of ice formed by cooling sterile saline being contaminated, and bringing great convenience to the lung transplantation work of medical staff.
