The application of vacuum pumps in medical devices includes steam sterilization, respiratory devices, mattresses, protective clothing, dental treatment equipment, and central vacuum systems
Vacuum pump application
Steam sterilization
Sterilization of various devices and equipment is crucial in medical practice, hospitals, laboratories, and pharmaceutical equipment. The three different working cycles of a sterilizer: extracting air: air prevents hot steam from directly contacting the sterilized object, which is why it must be evacuated from the container. The air pressure should be reduced to 100 mbar (27 "HgV), and then hot steam should be injected. This process is repeated 3 to 4 times. Sterilization: at a pressure of 2-3bar (30-45 psi) and 121-134 ° C; Inject steam into the container at a temperature of 250 to 275 ° F and kill all bacteria. During the sterilization process, the vacuum pump does not work. Drying: After sterilization is completed, the vacuum pump exhausts the air inside the sterilizer until the vacuum degree reaches 50mbar (28.5 "HgV), which is used to dry the sterilized object
Central vacuum system
Hospitals and surgical clinics use central vacuum systems to extract liquids generated during surgery. Install a separator near the surgical equipment to separate particles of different sizes and then handle them appropriately. Usually, due to limited space near surgical equipment, vacuum systems can be installed in distant locations
