Description

Novel protection of avoiding respiratory infectious disease to spread device

Technical Field

The utility model relates to a medical treatment protection facility field, in particular to novel avoid protective device of respiratory infectious disease transmission.

Background

Pneumonia infected by the novel coronavirus can be transmitted by people, the virus infectivity is extremely strong, and the transmission of the pneumonia through respiratory droplets, contact and aerosol is a main transmission path of the novel coronavirus. The medicine dispensing window of the outpatient pharmacy of most traditional medical institutions in China adopts a local open design so as to realize that medical staff dispense medicines outwards, and the medical staff has the risk of infection due to the fact that the medical staff is in close contact with patients and is spread by respiratory droplets and aerosol. Not only hospitals, such as bank office windows, station ticket windows, letter visit reception windows and the like, also adopt local open structures close to hospital dispensing windows, and workers also have the risk of spreading viruses through respiratory droplets and aerosols.

The patent of application No. 201320851413.1 discloses a medical infectious disease prevention operation box, which comprises a support frame, a protective cover, a transparent observation hole, a push-pull glass door, an operation hole, an oxygen tube, an exhaust tube and an ultraviolet germicidal lamp, wherein the protective cover is arranged around the support frame, the transparent observation hole is arranged around and at the top of the protective cover, the push-pull glass door is arranged on one surface of the protective cover, the operation hole is arranged on the push-pull glass door, and the oxygen tube and the exhaust tube are respectively arranged at the top of the protective cover; the bottom of the protective cover is provided with an ultraviolet germicidal lamp and an electric heating furnace, the ultraviolet germicidal lamp and the electric heating furnace are connected with an external power supply, and the ultraviolet germicidal lamp and a control switch of the electric heating furnace are arranged on the supporting frame. Can realize the isolation of the infectious patient and the medical care personnel without influencing the daily nursing work. However, the periphery and the top of the protective cover are provided with transparent observation holes, and the push-pull glass door is provided with operation holes, the arrangement of the holes is convenient for operation, but air airflow in the box body still can flow to the space outside the box, and the protective cover cannot play a role in complete isolation for viruses which are mainly propagated by air media and have strong transmissibility like novel coronavirus.

The patent of application No. 201721163908.X discloses an infectious disease prevention cage, when using, at first, keep apart the translucent cover and remove suitable position, stretch out the telescopic link again, cover patient in it with keeping apart the translucent cover, open sterilamp and scavenger fan again, take out the inside air of translucent cover through the scavenger fan, filter treatment is carried out to the inside air of keeping apart the translucent cover through filter equipment, prevent that the virus from spreading to the air in, carry out the pollution of second time, lead to giving other patients with the virus propagation, later take out fresh air and supply patient's use in keeping apart the translucent cover again. The device is suitable for local isolation of patients in specific departments of a hospital through the isolation transparent cover, and is not suitable for being applied to open spaces with dense and complex mobility of personnel such as a hospital dispensing window, a bank office window, a station ticket selling window and a letter and visit receiving window.

Therefore, it is highly desirable to design a new protection device for preventing the transmission of respiratory infectious diseases, which can avoid the infection risk to the maximum extent.
