The closer the first magic tape pad is to the back side of the head, the closer the first magic tape pad is to the back side of the head, and infection caused by bacteria contacting with the face skin due to separation of the isolation protection mask when the isolation protection mask is worn on the head of a person is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of infectious diseases, in particular to an isolation and protection mask. Background Art

[0002] Infectious diseases are an important field in medicine that focuses on the study, diagnosis, and treatment of a variety of infectious diseases that may be caused by bacteria, viruses, fungi, or parasites. They use their expertise to quickly locate pathogens, develop treatment plans, and monitor the patient's disease progression, so the public needs to be vaccinated in a timely manner, educate patients and the public, and formulate health policies.

[0003] According to a kind of isolation protective mask disclosed in patent search announcement number CN215585285U, its beneficial effects are: by arranging an air inlet pipe and an air outlet pipe in the eye mask, the internal air can be replaced by injecting air to avoid the generation of fog due to excessive humidity, and a valve core is provided on the air outlet pipe to prevent air backflow and prevent outside air from entering the eye mask, thereby improving the safety of medical staff.

[0004] Generally, Velcro is needed to wear the isolation protection mask on the back of the head to prevent the person from respiratory infection. However, the Velcro may loosen and fall off during the bonding process, which may inadvertently release the isolation protection mask from the head, and pathogens may also stick to the facial skin of the person, causing infection.
