Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a medical infectious disease protection hood. Background Art

[0002] Currently, the main medical devices for preventing viruses on the market are protective clothing, protective masks, goggles, and protective gloves. Based on the main transmission routes of infectious viruses through saliva, respiratory infections, and contact infections, many medical staff are also infected by the current epidemic prevention devices.

[0003] Problems existing in the facial protection of the prior art: too many medical devices need to be worn, which on the one hand causes waste of material costs and cannot provide good protection for the face. Moreover, the overall protective hood on the market currently cannot be used for eating and drinking, and the internal temperature is likely to be too high in the sealed hood, resulting in fogging of the lens and affecting the work of medical staff. Summary of the Invention

[0004] The purpose of the present invention is to ensure the safety of the work of medical staff. Therefore, a medical infectious disease protection hood is provided to solve the problems raised in the above background art. The present invention seals the nose clip against the nose and the lens into two areas, and the hot air generated by breathing will not cause the lens to fog. In addition, the angle of the lens can be adjusted. At the same time, a straw can be used to drink water and intake liquid food through a movable plug. In addition, if a traditional mask is worn for too long, there will be indentations on the face. In this application, a silicone material is provided at the skin contact area to protect the skin. In addition, two filter layers are provided, which can block viruses well.
