At present, the basic use of the operating room of the domestic hospital is imported medical variable-temperature water tank.
The medical variable-temperature water tank used at present has a plurality of defects, and some of the defects are even fatal. For example, the medical variable-temperature water tank has large water quantity (about tens of liters), when the water in the variable-temperature water tank is replaced, the medical staff in the hospital cannot finish the operation and can only enter an operating room to be replaced by a manufacturer or a professional, so that the hidden pollution trouble is increased; the temperature-changing water tank is provided with an outlet and an inlet to form a closed environment, and water is usually replenished after water is deficient, so that bacteria can be easily bred on one hand, and water in the temperature-changing water tank is inconvenient to replace on the other hand due to the structural design; this water replenishment also results in very old and dirty water in the tank; the old dirty water in the water tank can also cause the generation of bacterial aerosol, and the dirty water of the temperature-changing water tank can enter the membrane lung in an accident state, so that the death of a patient is often caused.
It has been reported in foreign articles that medical variable temperature water tanks have caused bacterial infection in wounds of patients who do cardiac surgery, and the bacteria detected to be infected are the same as bacteria growing in water of variable temperature water tanks used in the surgery. It is easy to speculate that the temperature-changing water tank is used in operation, the wound is opened, and the heart is infected after aerosol of the temperature-changing water tank enters the body from the wound.
For a long time, both domestic and foreign, attempts have been made in the art to improve such pollution problems, such as replacing the water tank with the circulating water from the operating room wall, but this solution is difficult to implement in practice, i.e. requires modification of the original hospital facilities, since the conventional operating room wall is not designed with a flowing water source, and the water source facilities are rebuilt to introduce the water source, which obviously is too large for the hospital, and is too costly.
From a general more specific point of view, the current medical variable-temperature water tank product design, such as a non-detachable water tank design scheme adopting a small-size water filling port, has the following serious problems:
1. the water inlet and the water outlet are easy to leak, pollution is generated, and harmful substances such as toxic aerosol and the like are bred;
2. in the actual use process, the water tank cannot be disassembled, so that the water is very inconvenient to change, the auxiliary water adding and sewage collecting equipment is needed, and a manufacturer or a professional maintainer is needed to enter an operating room for operation;
3. the disinfection function is not realized, frequent water replacement is needed, the maintenance is inconvenient, and the long-term use cost is high;
4. the compression refrigeration system adopting freon as refrigeration working medium has the advantages that the ozone layer is destroyed by the working medium discharged after slow leakage or fault leakage is used for a long time, and the environment is not protected;
5. the water tank system is huge, difficult to carry and extremely easy to generate faults in the actual use process.
The present invention solves the above-mentioned problems with existing tanks. The medical variable-temperature water tank design scheme is reliable, has obvious characteristics and remarkable superiority compared with the existing inlet variable-temperature water tank. The medical variable-temperature water tank has the advantages that the problems that the water inlet and outlet of the traditional variable-temperature water tank are easy to leak, pollution is generated, and harmful substances such as toxic aerosol are bred are greatly reduced through the convenient water changing design; in the actual use process, the water tank with the trolley function can be quickly disassembled conveniently, water is conveniently changed, a manufacturer or a professional maintainer does not need to enter an operating room to operate, and common medical staff can easily complete the water changing operation, so that the hidden danger of pollution is reduced in the operating room; the medical variable-temperature water tank has the sterilization functions of ultraviolet sterilization and the like, thereby greatly reducing the water changing frequency, reducing pollution, reducing the working strength for medical staff and having lower long-term use cost; the pollution-free refrigerant is designed and used, so that the refrigeration efficiency is improved, and the energy conservation and environmental protection are realized; the design adopts the products such as the heat conduction film with extremely high heat conductivity parameter, the interface material with low contact thermal resistance, and the like, combines the means of human engineering design, and the water tank system is small and exquisite, high-performance and durable, and has extremely low failure rate.
