Monitor of vacuum sterilizer

Abstract

A monitor device for the vacuum sterilizer features that the outputs of the pressure and temp sensors in the internal chamber of sterilizer and the humidity sensor in the external cylinder are connected to the input of single-chip computer, whose output is connected to terminal.

Description

Technical field: [0001] The invention relates to a monitoring device for the sterilization effect of a vacuum pressure steam sterilizer. Background technique: [0002] After decades of development, the pulsating vacuum pressure steam sterilizer has become increasingly mature. It has the advantages of reliable sterilization effect, high sterilization efficiency, no residual toxic substances after sterilization and low sterilization cost. It is widely used in medical treatment. In industries such as medicine, scientific research and pharmaceuticals, it is even more widely used in hospitals. The main factor affecting the sterilization effect of the pulsating vacuum pressure steam sterilizer is cold air. Once the residual amount of cold air in the inner chamber of the sterilizer exceeds 2%, it is likely to form a cold air mass during the sterilization process to hinder the pressure steam on the equipment. Penetration can eventually lead to sterilization failure (can cause large...

Problems solved by technology

However, the B-D test must be realized with the help of chemical indicators, and the limitations are increasingly prominent: one is the high cost of testing, and the cost of only standard chemical testing kits (mostly imported) and steam is more than 120 yuan each time. It is often not done according to the regulations or even not done; the second is that in addition to being affected by the cold air mass, the detection effect is also affected by non-monitoring target factors such as the quality of chemical test paper, pressure steam quality, effective action time, temperature, humidity, and visual differences. It leads to distorted results and also affects the normal use of the sterilizer; the third is that with the rapid development of science, most of the current pulsating vacuum pressure steam sterilizers have developed into modern equipment with excellent performance and a high degree of automation, and the failure rate Relatively small, dozens or even hundreds of B-D tests may not detect the existence of a single cold air mass, the actual significance of the B-D test is debatable

It can be seen that the technology of B-D experiment is getting more and more lagging behind and will be eliminated by new technology
