Stomatological treatment chair with clean positive-pressure air curtain

Abstract

The invention provides a stomatological treatment chair with a clean positive-pressure air curtain, and relates to a novel stomatological treatment chair which is provided with a clean positive-pressure air system, can form a downward blowing type clean air curtain between mouths and noses of a doctor and a patient and is provided with a polluted air recovering system. The stomatological treatment chair is characterized in that a pressure equalizing box with an air filtering layer is connected to the upper end of an elbow which is fixed to the rear surface of a headrest; the lower end of the elbow is connected with a positive-pressure air valve and then is connected with the clean positive-pressure air system; corresponding vacuum branch tubes at two sides of a seat board are connected with a main vacuum tube; a filtering net is arranged in a vacuum absorbing head which is connected to a vacuum valve at an upper head of each vacuum branch tube. With the adoption of the stomatological treatment chair with the clean positive-pressure air curtain, water mist containing saliva, blood and bacteria of the patient can be prevented from spreading between the doctor and the paint; particularly, the stomatological treatment chair has an important social significance on preventing infectious diseases spread by the ways above, such as venereal disease, aids, influenza hepatitis B and phthisis. The stomatological treatment chair is novel in structure design, practical, scientific and reasonable; the treatment quality and level of a department of stomatology of a modern hospital can be improved; the stomatological treatment chair is suitably popularized and applied to the department of stomatology of the hospital at all levels and the dental clinics.

Description

technical field [0001] The invention relates to a hospital dental chair, in particular to a dental chair with a clean positive pressure air curtain which can prevent water mist pollution containing patients' saliva, blood and germs and cross transmission of diseases between doctors and patients. Background technique [0002] The dental chair is the most basic medical equipment in the stomatology department of the hospital; but at present, during the use of mobile phones, dental cleaners and other equipment in the stomatology department, a large amount of water mist containing patients' saliva, blood or germs will be generated and spread in the air. In the process of diagnosis and treatment of oral diseases, due to the comparison of the distance between the mouth and nose between doctors and patients In the near future, it may cause the transmission of respiratory infectious diseases between doctors and patients; especially for infectious diseases such as sexually transmitted...

[0002] The dental chair is the most basic medical equipment in the stomatology department of the hospital; but at present, during the use of mobile phones, dental cleaners and other equipment in the stomatology department, a large amount of water mist containing patients' saliva, blood or germs will be generated and spread in the air. In the process of diagnosis and treatment of oral diseases, due to the comparison of the distance between the mouth and nose between doctors and patients In the near future, it may cause the transmission of respiratory infectious diseases between doctors and patients; especially for infectious diseases such as sexually transmitted diseases, AIDS, influenza, hepatitis B, tuberculosis and other infectious diseases transmitted through saliva, blood, and respiratory system. There is a chance of infection between patients
