Problems solved by technology

[0013] In the conventional steam sterilizer disclosed in Patent Document 1, a vacuum pump is used to evacuate the inside of the pressure vessel, but there is a problem that an additional power supply (AC200V) for driving the pump is required, the equipment becomes large-scale, and it cannot meet the requirements. Requirement to reduce power consumption

Embodiment Construction

[0032] Hereinafter, the steam sterilizer of this embodiment is demonstrated based on drawing.

[0033] figure 1 It is a schematic diagram which shows the structure of a steam sterilizer.

[0034] The steam sterilizer 30 includes a pressure container 32 for accommodating an object to be sterilized, and a vacuum generating member 34 connected to the pressure container 32 for bringing the inside of the pressure container 32 into a vacuum state.

[0035] The pressure vessel 32 has a double-layer tank structure including an inner tank 35 and an outer tank 36 , and the gap between the inner tank 35 and the outer tank 36 is a jacket portion 38 . Objects to be sterilized, such as bandages, scalpels, forceps, or surgical gowns, are accommodated in the inner tank 35 . Saturated water vapor described later can be introduced into the jacket portion 38 to heat the inner tank 35 to a predetermined temperature and maintain the temperature.

[0036] A steam pipe 41 for introducing saturat...

Abstract

Provided is a steam sterilizer capable of performing water vapor sterilization without using a vacuum pump as a mechanism for bringing the inside of a pressure vessel into vacuum. The steam sterilizer includes a pressure vessel (32) which stores an object to be sterilized and in which sterilization is performed with water vapor supplied from a steam piping, and vacuum-generating means (34) which is connected to the pressure vessel (32) and brings the inside of the pressure vessel (32) into a vacuum state. The vacuum-generating means (34) includes a water ejector (48), a tank (50) for storing supply water supplied from an outside, and a pump (52) for supplying the supply water inside the tank (50) to the water ejector (48).

Description

technical field [0001] The invention relates to a steam sterilizer for sterilizing objects to be sterilized by steam. Background technique [0002] In hospitals and the like, it is necessary to sterilize objects to be sterilized, such as bandages for treatment, scalpels, forceps, and surgical gowns. In the sterilization of such objects to be sterilized, a steam sterilizer having a pressure vessel for accommodating the object to be sterilized is often used. [0003] A general steam sterilizer operates in such a way: by introducing saturated water vapor into a pressure vessel, pressurizing and heating, and maintaining a predetermined pressure and temperature for a constant time to sterilize the object to be sterilized (for example, refer to Patent Document 1). [0004] In the steam sterilizer described in Patent Document 1, the sterilization chamber for accommodating the object to be sterilized is a pressure vessel with a double-layer tank structure composed of an inner tank...
