Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for spraying a medical solution for sterilization or the like, particularly to a hospital room or an operating room.

[0002]

2. Description of the Related Art In recent years, nosocomial infections such as MRSA and Legionella have become a problem. Therefore, hospital rooms and operating rooms are sterilized. For this purpose, a commonly used chemical is formalin, in which paper or nonwoven fabric is infiltrated into this solution tank and heated by a heater to generate gas, or the solution is supplied from a formalin solution tank to a pan with a heater. The solution was vaporized with this pan, but in each case, it took time to fill the room with a gas having a sterilizing effect of a certain humidity or higher, and a relatively large amount of the solution was required.

[0003] Furthermore, after disinfection and sterilization, ammonia is vaporized and neutralized by the same method. However, this also requires time and consumes a large amount of ammonia.

[0004] Further, both methods require two tanks of a sterilizing solution and a neutralizing solution, each of which must be provided with a vaporizing means, and there is a problem that the apparatus becomes large.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of disinfecting and sterilizing sufficiently effectively by reducing the consumption of a chemical solution in a short time.

Another object of the present invention is to provide an apparatus which can be used in a small size and which can use a plurality of types of chemicals and which can be easily handled.

[0007]

In order to solve the above-mentioned problems, in the present invention, a nozzle for blowing out compressed air is arranged near an opening of a cylindrical hood, and the tip of a chemical solution supply pipe is made to face this nozzle. , Place a blower behind this nozzle,
A compressor for connecting a plurality of chemical liquid containers to the chemical liquid supply pipe via a switching valve and supplying compressed air to the nozzle.
From the air intake of the blower to the blower.
Thus, a configuration arranged in the air circulation zone is adopted.
Also, place a pressure switch on this air intake and
It is good to be able to detect clogging of ruta.
