Description

Isolation heating device and water injection pump system with heating function Technical Field The utility model belongs to the technical field of medical appliances, and particularly relates to an isolation heating device and a water injection pump system with a heating function. Background The water injection pump is an auxiliary device used in cooperation with surgical treatment, and washes tissues to remove blood, excrement and other organic substances by supplying water to the body, the lumen, the body cavity or the internal cavity of the body, so as to improve the visibility of diagnosis and treatment in the diagnosis and treatment process. At present, a water injection pump used clinically is used for conveying sterile liquid to a wound surface part in a pressurized manner through a peristaltic pump so as to finish the cleaning of the wound surface. In some operations, the injected sterile fluid needs to be close to the body temperature of the patient, and the fluid at room temperature can cause muscle contraction, which is detrimental to the operation. The endoscope water supply device used clinically at present does not have a heating function, and sterile liquid needs to be heated in advance through a water bath and then pumped in through a water injection pump in operation. The initial temperature of hot water for water bath is not well controlled, and along with the reduction of the water temperature, the temperature of sterile liquid also fluctuates, which is not friendly to operation. Chinese patent document CN222102246U (202420718248.0) discloses a temperature-controllable animal perfusion peristaltic pump, wherein an isolating heating device which can be extended and contracted on a hose is sleeved at one end of the hose, and the isolating heating device is used to make the perfused solution constantly at a specified temperature when entering an animal or organ.
