[0002]

2. Description of the Related Art In a hospital, an operating room, ICU, CU
MRS from patients by disinfecting U, general ward, outpatient room, etc.
It is necessary to prevent so-called nosocomial infections such as A (methicillin-resistant Staphylococcus aureus), and conventionally, disinfection was performed by spraying a disinfectant solution or irradiation with a germicidal lamp. According to the above, disinfecting the entire hospital room requires a lot of man-hours, and since the worker must enter the room, special clothing that covers the body must be worn, so disinfection should be performed easily. However, there is a drawback that it is difficult for a nurse to find out the man-hours from busy nursing activities.

Further, when disinfecting by spraying formalin which is an effective disinfectant, there is a drawback that the strong odor of formalin remains after disinfection and the patient room cannot be used for a while after disinfection. there were.

The method using a germicidal lamp is convenient for disinfecting small devices such as medical instruments, but it is inconvenient for disinfecting large objects such as hospital rooms, and it is impossible to disinfect the shaded areas where ultraviolet rays cannot reach. There was a drawback.

After the solution is stored in a neutralizing solution supply tank equipped with a neutralizing solution supply valve, the disinfecting solution is supplied into the container of the vaporizer to be vaporized and diffused and exhausted into the room to be disinfected,
The neutralizing solution is supplied to the same container where the disinfectant solution is supplied to the end of the vaporizer to vaporize and diffuse and exhaust into the room, and then compressed air is discharged as fine bubbles into the deodorant solution to remove the deodorant solution. By vaporizing and diffusing and exhausting into the room, after disinfecting the room, the disinfectant solution remaining in the room is neutralized and the odor of the disinfectant solution can be deodorized. The purpose is to prevent hospital infections such as MRSA by increasing the disinfection with a gaseous disinfectant so that it can disinfect everywhere, and improve the safety of hospitals. For example, the odor of formalin disinfectant is removed. It is to be able to use the patient room afterwards immediately after disinfection.

Another object is to control the vaporizer, the disinfecting liquid supply valve, the neutralizing liquid supply valve, the deodorizing liquid vaporizing device and the exhaust device by the control device to disinfect, neutralize and deodorize the room to be disinfected. It is to be able to perform each work of step 1 automatically automatically, and this makes it possible to easily perform disinfection work using a small disinfection device and reduce the burden on the nurse. It is to be able to concentrate on the original nursing work.

A disinfecting liquid supply tank for supplying the required amount of the stored formalin to the container, and a neutralizing liquid supply tank for supplying the required amount of the stored ammonia to the container by providing a neutralizing liquid supply valve at the discharge port. , A malic acid vaporizer for storing liquid malic acid and discharging compressed air into the malic acid as fine bubbles to vaporize the malic acid, and disinfect the vaporized gaseous formalin, ammonia and malic acid An exhaust device for diffusing and exhausting into the room is provided, and a necessary amount of the liquid formalin is supplied from the disinfectant solution supply tank to the container to be vaporized and diffused into the room to be disinfected. After sterilization, a necessary amount of the liquid ammonia is supplied from the neutralization liquid supply tank to the same container to be vaporized and diffused into the chamber to be sterilized to neutralize the formalin remaining in the chamber, Further, the indoor automatic sterilizer is characterized in that the malodor is deodorized in the room by the deodorant liquid vaporizer. 4. A vaporizer comprising a container having an open upper portion and a heater disposed above the container for heating and vaporizing liquid formalin and liquid ammonia stored in the container, and a discharge port. An antiseptic solution supply valve is provided to supply the required amount of the stored formalin to the container, and a required amount of the stored ammonia is stored in the container with a neutralizing solution supply valve provided at the discharge port. A neutralization liquid supply tank for supplying, a deodorizing liquid vaporizer for storing liquid malic acid and discharging compressed air supplied from a blower into the malic acid as fine bubbles to vaporize the malic acid, An exhaust device for diffusing and exhausting the gaseous formalin, ammonia, and malic acid into the chamber to be disinfected, and the formalin, ammonia, and ammonia from the volume of the chamber to be disinfected. And the required amount of the malic acid is calculated, and the calculated result is stored, and the disinfecting liquid supply valve is opened to supply the calculated required amount of the formalin to the container, which is heated by the heater to be vaporized. After the gaseous formalin is diffused into the room by an exhaust device and sterilized, the neutralizing liquid supply valve is opened to supply the calculated necessary amount of the ammonia to the container and heat it by the heater to vaporize it. Then, the gaseous ammonia is diffused into the chamber by the exhaust device to neutralize the formalin remaining in the chamber, and then the blower is operated to discharge compressed air into the malic acid as fine bubbles. A chamber provided with a control device that vaporizes the malic acid and controls the exhaust device to diffuse the gaseous malic acid into the chamber to deodorize the malic acid. Automatic sterilization device.
