Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a controllable timing ultraviolet irradiation type medical waste garbage can and a working method.
Background
A medical waste receptacle is a receptacle for holding waste that is generated by health care facilities during medical, preventive, health care and other related activities and has direct or indirect infectious, toxic and other hazardous properties.
Aiming at the conventional medical waste, the medical waste garbage can opened by foot step can be discarded in the can between the opening and the closing. Under the background of prevention and control of new coronary pneumonia epidemic situation, the transmission through respiratory droplets and close contact is the main transmission route. There is a potential for transmission through aerosols when exposed to high concentrations of aerosols for extended periods of time in a relatively closed environment. In fact, when disposing medical waste, or according to the order of removal and the removal area required by the documents, there is a neutral position where medical staff removes and wears the mask, especially after the cap and the medical protective mask are removed by hand hygiene in the second removal area and before the medical surgical mask is worn by hand hygiene. This neutral position exposes the medical staff to the risk of exposure in the second stripping zone.
In a suspected or confirmed new crown patient fixed-point recovery and treatment ward, medical wastes exposed in a new crown virus pollution environment are abandoned in the garbage can, and aerosol diffusion generated by opening and closing can become a hidden danger of infection of medical care personnel when related medical wastes are treated. In an isolation ward, the most economical and effective air disinfection method is to use a medical ultraviolet lamp which is regularly detected in intensity and has effective wave band wavelength and intensity to perform radiation disinfection at regular time. However, the medical ultraviolet lamps on the market at present often use lamp boxes and moving vehicles as carriers, and the products for disinfecting the air and the object tables in the barrels with short distance and high strength are not applied, so that in the epidemic prevention and control normalization, products which can contain medical wastes and can be regularly disinfected during storage are needed, the prevention and control details are perfected, and the effect that 1+1 is greater than 2 is achieved.
The prior art has the irradiation type disinfection of a medical ultraviolet lamp, and has the defect that the simple ultraviolet irradiation can only disinfect the ward environment and the object surface and can not disinfect the air in the medical waste garbage can so as to reduce the generation of aerosol. The existing medical waste garbage can only plays a role of a containing container and does not prevent aerosol transmission problems. In the new crown isolation ward, the operation range is reduced, the operation is slow, and the double-layer garbage bag gooseneck knot sealing is disposed only when medical waste reaches the packaging bag 3/4 by nursing staff. In conclusion, various products currently circulated in the market cannot be fused and used at the same time, and no related application product makes it difficult to control detailed standards in the link of medical waste treatment in the ward in actual work. Therefore, a controllable timing ultraviolet irradiation type medical waste garbage can and a working method thereof are urgently needed to solve the problem of incomplete disinfection in the garbage can.
