CTOnews.com February 13 news, according to the Chinese Academy of launch vehicle Technology released, the Rocket Institute developed Huiyi-I ECMO (extracorporeal lung support equipment) product has been released. Recently, the blood thermostat ("variable temperature water tank"), the core device of extracorporeal membrane oxygenation equipment (ECMO) independently developed by the Air Department of Rocket Institute, has made new progress.

In view of the problems of inlet and outlet pollution and inconvenient maintenance of similar imported equipment, and with the goal of asepsis, easy cleaning and miniaturization, the variable temperature water tank adopts the refrigeration / heating variable temperature circulation system of all-solid-state device. it has greatly broken through the key core technology sticking problem, and reached the intention of cooperation with Beijing Anzhen Hospital affiliated to Capital Medical University.

ECMO is used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure and is widely used in the operating room of patients with severe cardiopulmonary failure. CTOnews.com learned that the variable temperature water tank, as the core part of ECMO, is a driving device for providing heated water, cooling water and raw water for heat exchangers in the blood heat exchange system of cardiopulmonary bypass, which is used by medical units to adjust the temperature during cardiopulmonary bypass.

The variable temperature water tank developed by the Air Department is based on three key technologies that have been mature and applied to aerospace products: thermoelectric refrigeration, accurate temperature control, and thermal insulation.

The schematic diagram of the variable temperature water tank of the △ airfront part relies on the multi-disciplinary computer-aided simulation design capability as the overall research and design unit, and the researchers of the airfront department accurately simulate the key physical parameters such as flow field temperature, structure strength, electric power consumption and so on, and realize the omni-directional accurate prediction with the actual deviation of ±0.1℃.

△ variable temperature water tank structure schematic diagram in addition, by greatly improving the internal structure of the traditional water tank, the device not only effectively improves the heat and cold heat transfer efficiency, but also increases the ultraviolet eliminate virus function, which is more convenient for the cleaning and maintenance of the device, and greatly reduces the risk of surgical death caused by water tank pollution. A pull-up water tank replacement mechanism is added to shorten the water replacement time from 1 hour to 3-5 minutes, which greatly improves the work efficiency of medical staff.

Schematic diagram of △ portable water replenishment and storage mechanism at present, after more than ten rounds of demonstration, the device has completed the simulation design of each system and the construction of digital three-dimensional structure, and the core key technology has applied for international patent protection and is about to enter the stage of prototype development.
