Disinfection and sterilization device of medical negative pressure suction system

Abstract

The invention discloses a disinfection and sterilization device of a medical negative pressure suction system. The device comprises a sterilization box, a high-temperature sterilization frame is fixedly arranged in the center of the inner cavity of the sterilization box, an electric heating pipe is fixedly arranged on the inner side of the high-temperature sterilization frame, activated carbon filter boxes are fixedly arranged on the two sides of the inner cavity of the sterilization box, and ultraviolet lamps are fixedly arranged on the outer sides of the activated carbon filter boxes. The ultraviolet lamps are connected to a power supply to generate ultraviolet light to sterilize waste gas, the activated carbon filter boxes are used for deodorizing and filtering the waste gas, the electric heating pipe emits high temperature of 200 DEG C to perform high-temperature sterilization treatment, and the disinfected and sterilized waste gas enters a waste gas pipe from an exhaust pipe and is finally discharged into air through the exhaust pipe. According to the disinfection and sterilization device, the technical principle of high-temperature inactivation is adopted to treat highly-polluted waste gas exhausted from a hospital vacuum suction system, bacteria, microorganisms, viruses and the like possibly carried in the waste gas are inactivated and then cleanly exhausted, and the practicability is good.

Description

technical field [0001] The invention relates to the technical field of medical disinfection and sterilization, and more specifically, the utility model relates to a disinfection and sterilization device of a medical negative pressure suction system. Background technique [0002] The negative pressure gas generated by the suction system of the medical center is a kind of medical gas commonly used in clinical practice in hospitals. It is used to remove thick phlegm from patients’ wounds and oral cavity, and remove body fluids and accumulated water in patients’ surgical procedures. The air supply pipeline is exhausted to the atmosphere after being pumped by the vacuum pump equipment at the central suction station; [0003] The existing technology has the following disadvantages: because the gas extracted from the clinical gas point contains bacteria, microorganisms or viruses with a high concentration in the patient's body, a large number of bacteria, microorganisms or viruses ...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following disadvantages: because the gas extracted from the clinical gas point contains bacteria, microorganisms or viruses with a high concentration in the patient's body, a large number of bacteria, microorganisms or viruses are accumulated in the central suction device, and the gas is not used. After sterilization treatment, it is directly discharged into the atmosphere, which has a greater risk of infection. In the industry, the gas is not sterilized and discharged in the central suction station. Especially for infectious disease hospitals, the risk of infection is extremely high, and it is easy to cause hospital cross infection
