Sterile sealing cover structure applied to lung transplantation ice maker

Abstract

The invention discloses a sterile sealing cover structure applied to a lung transplantation ice maker. The sterile sealing cover structure comprises a sterile cover towel and a sterile cover body, the sterile cover body is arranged on the sterile cover towel and located at the position of a receding hole, one side of the sterile cover body is hinged to the sterile cover towel, an observation hole used for observing the icing condition of sterile normal saline in a sterile ice-making basin is formed in the middle of the sterile cover body, a plurality of layers of sterile sealing cover films made of transparent soft plastics are arranged on the observation hole in the axial direction of the observation hole, and the sterile sealing cover films cover the sterile ice-making basin in a sealing mode. According to the sterile sealing cover structure, ice formed by the sterile normal saline in the sterile ice-making basin can be in a sealed state in other time except for use, the contact time of the ice and the external environment is shortened, the probability that the ice formed by cooling the sterile normal saline is polluted is effectively reduced, and great convenience is brought to lung transplantation work of medical staff.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an aseptic cover structure applied to a lung transplant ice maker. Background technique [0002] Experimental research on lung transplantation dates back to the early 20th century. Human lung transplantation began in 1963. However, in 1963-1983, the longest survival time of nearly 40 surgical patients did not exceed 10 months. With the advent of cyclosporine A in the 1970s and the advancement of transplantation technology, in 1981, Stanford University Hospital in the United States first achieved the success of combined heart-lung transplantation; in 1983 and 1986, the lung transplantation group in Toronto, Canada successfully performed single-lung transplantation. Transplantation and double lung transplantation ushered in a new era of lung transplantation. Since then, lung transplantation has developed rapidly. By 1997, the number of surgical cases had reached 6639, t...

Problems solved by technology

[0004] At present, most of the cooling methods used by medical staff during lung transplantation are to spread ice chips around the donor lungs, and the ice chips are made by an ice machine. When making ice chips, medical staff need to Put a refrigeration medium, such as alcohol, in the cooling tank of the ice machine, then place the aseptic ice-making basin on the cooling tank, and then inject sterile saline into the aseptic ice-making basin, and the sterile saline will be refrigerated It is slowly cooled under the action of the medium, and finally forms ice. When the medical staff need to spread ice chips around the donor lung, they only need to use a sterile ice shovel to shovel on the ice formed by sterile normal saline, and then put the The ice chips shoveled from the ice formed by sterile normal saline can be spread around the donor lungs. During this process, the sterile ice-making basins are all open and in contact with the external environment for a long time, and the sterile normal saline is cooled. The formed ice is very easy to be contaminated, which increases the probability of contamination of the ice formed by the cooling of sterile saline, which brings great inconvenience to the medical staff in the lung transplantation work
