Background
The temperature-changing water tank is temperature-changing equipment in an extracorporeal circulation heat exchange system. According to different operations, the temperature-changing water tank can be applied to a plurality of operating departments.
At present, the medical variable temperature water tank is basically imported in the operating room of the domestic hospital.
The medical temperature-changing water tank used at present has many disadvantages, some of which are even fatal. For example, the medical variable temperature water tank has a large water volume (about tens of liters), and is very inconvenient to replace water in the variable temperature water tank, so that medical staff in a hospital cannot complete the operation and only needs to enter an operating room for replacement by a manufacturer or a professional, thereby increasing the hidden danger of pollution; the temperature-changing water tank is provided with an outlet and an inlet to form a closed environment, usually water is supplemented after water shortage, and due to the structural design, on one hand, bacteria can be easily bred, and on the other hand, the water in the temperature-changing water tank is inconvenient to replace; this refill also results in the water in the tank being very old and dirty; the water in the water tank is old and dirty, meanwhile, the water can also cause the generation of bacteria aerosol, and the dirty water in the temperature-changing water tank can enter the membrane lung in an accident state, and in this case, the death of a patient can be caused.
It has been reported in foreign articles that medical variable temperature water tanks cause bacterial infection of wounds of patients who have undergone cardiac surgery, and the infected bacteria are the same as bacteria grown in water in the variable temperature water tank used during surgery. It is easy to speculate that the temperature-variable water tank is used in the operation, and aerosol in the temperature-variable water tank enters the body from a wound and infects the heart because the wound is open.
For a long time, both domestic and foreign, the art has tried to improve such pollution problems by some means, such as replacing the water tank with circulating water from the wall of the operating room, but this solution is difficult to implement in practice, i.e. it requires the original hospital facilities to be modified, since the normal wall of the operating room is not designed with a flowing water source, and the water source facilities are re-constructed to introduce the water source, which obviously is too large and costly for the hospital.
In a more specific view, the current design of medical variable temperature water tank products, such as non-detachable water tank design schemes using small-sized water filling ports, 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 inconvenient to change, 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 device has no disinfection function, needs frequent water change, is inconvenient to maintain and has high long-term use cost;
4. the compression refrigeration system adopting Freon as a refrigeration working medium damages the ozone layer by using the working medium discharged after slow leakage or fault leakage for a long time, and is not environment-friendly;
5. the water tank system is large in size, difficult to carry and easy to break down in the actual use process.
The present invention solves the above-mentioned problems of the conventional water tank. Compared with the existing imported variable temperature water tank, the design scheme of the medical variable temperature water tank is reliable, obvious in characteristics and remarkable in excellence. The medical variable temperature water greatly solves the problems that the water inlet and the water outlet of the traditional variable temperature water tank are easy to leak, generate pollution, breed harmful substances such as toxic aerosol and the like through a convenient water changing design; in the actual use process, the water tank can be rapidly disassembled through the convenient water tank with the cart function, the water is convenient to change, a manufacturer or professional maintenance personnel is not required to enter an operating room for operation, and general medical personnel can easily complete the water changing operation, so that the hidden pollution danger of the operating room is reduced; the medical variable temperature water tank designed by the invention has disinfection functions such as ultraviolet disinfection and the like, so that the water changing frequency is greatly reduced, the pollution is reduced, the working strength is reduced for medical staff, and the long-term use cost is lower; the design and use of the pollution-free refrigerant improve the refrigeration efficiency, and are more energy-saving and environment-friendly; the design adopts products such as a heat conduction membrane with extremely high heat conductivity parameters, a low contact thermal resistance interface material and the like, and combines a human engineering design means, so that the water tank system is small and exquisite, high in performance, durable and extremely low in failure rate.
