Problems solved by technology
The pulsating vacuum sterilizer has a high sterilization rate, is easy to use and reliable, and represents the latest scientific and technological achievements in the sterilizer industry; however, defects that need to be improved are gradually exposed during use: the processing capacity (efficiency) of the sterilizer is not satisfactory, and the vacuum pump works intermittently Negative effects of mode on sterilizer reliability
[0011] The above-mentioned beneficial explorations have certain reference value, but there are still limitations in the exploration results

Embodiment Construction
[0036] As shown in Fig. 1(a), Fig. 1(b), and Fig. 1(c), the pulsating vacuum sterilizer in which the vacuum tank auxiliary vacuum pump vacuumizes the inner pot consists of an outer pot pressure and temperature sensor group 100, an inner pot pressure and The temperature sensor group 200, the outer pot valve group 300, the inner pot valve group 400, the vacuum pump 500, the vacuum tank valve group and the pressure sensor 600, the main control module 700, and the communication module 800. The sterilizer adopts a double pot of inner / outer pot body structure, the vacuum tank is a closed tank, and the steam generator provides high-pressure steam for the sterilizer; the outer pot pressure and temperature sensor group 100 includes an outer pot pressure sensor 110, an outer pot temperature sensor 120, and an inner pot pressure and temperature sensor group 200 Including inner pot pressure sensor 210, inner pot temperature sensor 220, outer pot valve group 300 includes outer pot steam int...

The invention discloses a pulsation vacuum sterilizer for vacuumizing an inner pot by a vacuum-tank-assisted vacuum pump and a method. The pulsation vacuum sterilizer consists of an outer / inner pot pressure and temperature sensor group, an outer / inner pot valve group, a vacuum pump, a vacuum tank valve group, a pressure sensor, a main control module and a communication module. The sterilization process is divided into an inner-pot vacuumizing process and a non-inner-pot vacuumizing process. For the inner-pot vacuumizing process, by means of the vacuum tank and the inner-pot valve group, one path of air in an inner pot is suctioned by the vacuum pump, and the other path of the air in the inner pot is diffused to the vacuum tank with high vacuum degree, so that the vacuumizing efficiency isdoubly increased, and the benefit for deeper vacuumization of the inner pot is achieved; when the air in the inner pot is diffused to the vacuum tank, the vacuum degree of the inner pot is changed suddenly, so that the benefit for exhausting the air at dead corners of the inner pot and small gaps of instruments to be sterilized can be achieved, and the sterilization quality is higher. For the non-inner-pot vacuumizing process, the vacuum tank is vacuumized by the vacuum pump, so that the continuous operation mode of the vacuum pump replaces the traditional intermittent operation module, and the efficiency and the reliability of the vacuum pump are improved.
Description
technical field [0001] The invention belongs to the technical category of a medical pulsating vacuum sterilizer, in particular to a pulsating vacuum sterilizer and a method for vacuuming an inner pot by a vacuum tank auxiliary vacuum pump. Background technique [0002] Medical devices are the vectors of blood and digestive tract transmission of pathogenic microorganisms--AIDS virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV); flaws in sterilization operations will surely Hazard to the health of patients and medical personnel. With the spread of severe viruses such as hand, foot and mouth disease, H1N1, H7N9, and SARS, the importance of medical device sterilization is increasing day by day; at present, medical sterilizers are included in the standard equipment list of medical units at all levels without exception. Sterilization methods are divided into two categories: physical and chemical sterilization; chemical sterilization methods include formaldehyde, ozone ...
