Negative-pressure mask device

Abstract

The invention belongs to the technical field of medical equipment, and discloses a negative-pressure mask device, which is used for assisting in treating and sampling respiratory tracts such as the mouth and the throat and comprises a negative-pressure mask unit and a negative-pressure driving unit. Wherein the negative-pressure mask unit comprises a mask and a trachea connector, the negative-pressure driving unit comprises a variable-frequency exhaust motor and an exhaust pipe, the variable-frequency exhaust motor is driven by motor wind power, local negative pressure is formed around the area, corresponding to the mouth and nose, of the mask, and gas is pumped out through the exhaust pipe. By means of the device, correspondingly, when medical staff operates the device, the medical staffcan be prevented from inhaling droplets and aerosol exhaled by a patient, the possible infection risk is reduced, and the device has the advantages of being compact in structure, convenient to operate, high in environmental adaptability and the like. The device has wide applicability, can be used for otolaryngology, pneumology, intensive care units, stomatology and the like, can be used for infectious disease control and the like, and can also provide basic equipment for intelligent medical services.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and more specifically relates to a negative pressure mask device. Background technique [0002] In the process of disease diagnosis and treatment, medical personnel sometimes need to perform oral and respiratory sampling and treatment operations. At this time, patients will discharge a large number of pathogens from the respiratory tract. These pathogens are bacteria or viruses, in the form of droplets, aerosols, etc. Spread in the air, pollute the operating surface environment, cause potential harm to medical staff, or directly cause medical staff to become infected. [0003] These dangerous behaviors can occur in the daily operations of departments such as stomatology, respiratory, infection, and ENT, as well as in some special examinations and treatments, such as nasopharyngeal sampling, tracheal intubation, and bronchial fiberscope Or douche and so on. [0004] At present, in the ...
