Description
Technical Field
The invention relates to the technical field of vacuum sterilizers, in particular to a sterilizer vacuumizing system.
Background
After the medical equipment is used, the medical equipment needs to be put into a sterilizer for sterilization, and all bacteria and liquid medicine residues on the equipment are removed, so that the cleanness and the sanitation of the equipment are kept, and the cross infection of patients is prevented. In order to ensure the sterilization effect, the sterilization process of the sterilizer generally includes the following steps: firstly, pumping out air in the pot body through a vacuum pumping system of a sterilizer, and reducing the pressure in the pot body to minus 80 KP; then, filling high-temperature high-pressure steam into the pot body, preserving heat for a period of time, and cleaning and disinfecting the equipment in the pot body by the high-temperature high-pressure steam; and finally, releasing pressure and releasing steam, pumping out air and water vapor in the pot body through a vacuumizing system of the sterilizer, then filling high-temperature and high-pressure steam for sterilization, and releasing pressure and releasing steam after sterilization is finished.
The vacuum pumping methods commonly used in the market at present mainly include two methods, one is a vacuum pump, and the other is a jet generator. The working mode of the vacuum pump is as shown in fig. 2, the piston in the cavity of the vacuum pump moves downwards, gas is sucked from the gas inlet valve port, then the piston moves upwards, and the gas in the cavity of the vacuum pump is discharged from the gas outlet valve port. The vacuum pump has high air pumping efficiency and can quickly pump out the air in the pot body at the beginning. However, when pumping steam subsequently, the temperature in the piston is high, and the volume of the steam in the cavity of the vacuum pump is compressed in the upward movement process of the piston, and the steam is quickly liquefied into water drops, and then is gathered in the cavity and is difficult to discharge; when the piston moves downwards, the volume of the cavity becomes large, the liquefied water drops are changed into water vapor again, and therefore the efficiency of the vacuum pump in pumping the water vapor is extremely low, and even the pumping vapor is ineffective. In addition, the apparatus may carry oil stains, and the piston is corroded when the oil stains are sucked into the vacuum pump, so that the service life of the vacuum pump is influenced. The jet generator works in such a way that a jet is formed at the nozzle through high-speed water flow, so that a low-pressure area is formed around the nozzle, and gas in the area can be continuously taken away by the jet, so that additional entrainment flow is formed, and the aim of vacuumizing is fulfilled. This vacuum can be used not only to evacuate air but also to evacuate water vapor. The device has high flow rate of extracting water vapor, but has extremely low flow rate of extracting air, so that the sterilizer adopting the mode has the defect of low flow rate of extracting air, the process of injecting water vapor into the pan body and then exhausting air and water vapor is needed for a plurality of times in the early stage of the sterilizer, and the process takes a very long time for ensuring that the air in the pan body is exhausted as much as possible, and the process takes twenty-thirty minutes.
