Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an aseptic sealing cover structure applied to a lung transplantation ice maker.
Background
Experimental studies of lung transplantation dates back to the beginning of the 20 th century. Human lung transplantation began in 1963. However, the maximum survival time of the last 40 patients after the operation in 1963-1983 is not more than 10 months. With the advent of cyclosporin a in the 70 th 20 th century and the advancement of transplantation technology, the university hospital stanford in the united states in 1981 first achieved the success of cardiopulmonary combination transplantation; in 1983 and 1986, the lung transplantation group of Toronto, Canada successfully performed single lung transplantation and double lung transplantation one after the other, opening a new era of lung transplantation. Thereafter, lung transplantation work rapidly progressed. By 1997, the number of operation cases has reached 6639, the 3-year survival rate reaches more than 50%, and the 5-year survival rate exceeds 40%. The patients after lung transplantation have good quality of life, can recover normal life, and some patients have been engaged in past work. Lung transplantation has become the only effective method for treating end-stage lung disease.
With the progressive maturation of lung transplant technology, donor preservation and perioperative treatments, the 1-year survival rate of lung transplants has increased from the past 70% to 85%. Lung transplantation starts with organ harvesting and requires cryo-preservation of the organ in order to reduce organ metabolism, reduce oxygen consumption, and reduce the production of oxygen radicals, thereby allowing better functioning of the organ after transplantation. In lung transplantation, medical personnel are concerned with the aspects of organ protection, from organ harvesting, to transplant surgery, to open perfusion, and the like. In the implementation process of the lung transplantation operation, donor lung tissues are taken out from a low-temperature refrigerator and placed in the chest cavity of a patient, and the body temperature of the patient can be constantly maintained at about 37 ℃ after anesthesia, so that the temperature of the donor lung can be quickly raised after the donor lung contacts the patient, the metabolism of cells can be further accelerated, and the cells can be quickly necrotized due to lack of blood supply, namely supply of nutrient substances. If the temperature is continuously maintained at 37 ℃ without treatment, the function of the donor lung tissue after transplantation is greatly reduced, so that the lung transplantation process needs to be continuously cooled.
At present, most of the cooling treatment methods used by medical workers in the lung transplantation process are to spread ice scraps around the donor lung, and the ice scraps are made by an ice maker, when the ice scraps are made, the medical workers need to put a refrigeration medium, such as alcohol, into a cooling tank of the ice maker, then place a sterile ice making basin on the cooling tank, then fill sterile physiological saline into the sterile ice making basin, the sterile physiological saline is slowly cooled under the action of the refrigeration medium, and finally form ice, when the medical workers need to spread the ice scraps around the donor lung, only a sterile ice shovel needs to be used for shoveling the ice formed by the sterile physiological saline, then the ice scraps shoveled from the ice formed by the sterile physiological saline are spread around the donor lung, in the process, the sterile ice making basin is open and is contacted with the external environment for a long time, and the ice formed by the cooling of the sterile physiological saline is extremely easy to be polluted, the probability of ice pollution formed by cooling the sterile normal saline is improved, and great inconvenience is brought to the lung transplantation work of medical personnel.
