Pulsating vacuum pressure steam sterilizer

Abstract

The invention relates to a pulsating vacuum pressure steam sterilizer, which comprises an inner chamber, a jacket, a steam generating device and a steam inlet mechanism, wherein the steam inlet mechanism comprises a filter, a jacket safety valve, a jacket air control angle seat valve, an inner chamber safety valve, an inner chamber air control angle seat valve and a drain valve, and the jacket air control angle seat valve is arranged between the jacket and the steam generating device; the inner chamber air control angle seat valve is arranged between the inner chamber and the steam generating device, and the inner chamber and the jacket are provided with the inner chamber safety valve and the jacket safety valve; the drain valve is arranged at the lower end of the steam inlet mechanism so as to drain condensate water in the steam inlet mechanism. Steam is supplied to the jacket and the inner chamber by the steam generating device respectively, so that steam can quickly flow into the inner chamber, and thus the work time of the sterilizer is shortened; meanwhile, the pressure of the jacket is always in a steady state, so that the corresponding steam temperature keeps steady, and thus the preheating and heat insulation effects of the jacket on the inner chamber are ensured.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a pulsating vacuum steam sterilizer in the medical equipment. Background technique [0002] In the medical industry, the pulsating vacuum steam sterilizer is a relatively common sterilization equipment, which uses high-temperature steam to sterilize medical devices. The pulsating vacuum steam sterilizer in the prior art is provided with an inner chamber, a jacket, a steam generating device and a steam inlet mechanism, wherein the steam inlet mechanism is provided with a filter, a jacket steam inlet air control angle seat, and an inner chamber inlet steam Air control angle seat valve, in which the jacket steam inlet air control angle seat is set between the jacket and the steam generator, and the inner chamber steam inlet air control angle seat valve is set between the jacket and the inner chamber, and the steam is first passed through the jacket The steam inlet line is used to f...

AI Technical Summary

Problems solved by technology

[0003] 1. The external saturated steam first enters the jacket, and then the jacket provides steam to the inner chamber. The steam needs to circulate from the jacket for one week before entering the inner chamber, resulting in slow steam entering the inner chamber and increasing the working time of the sterilizer

And if the steam inlet speed in the inner chamber is too slow, more condensed water will be produced on the sterilized items, which will lead to the phenomenon of "wet pack";

[0004] 2. When the steam enters the inner chamber from the jacket, the pressure of the jacket drops sharply, resulting in a sharp drop in the temperature of the saturated steam under the corresponding pressure, thus losing the insulation effect of the jacket on the inner chamber and increasing the generation of condensed water in the inner chamber
