Negative pressure hood for transferring respiratory infectious disease patient

Abstract

A negative pressure hood comprises a hood body, an exhaust pipe and an exhaust purification device, the upper end of the exhaust pipe is arranged in the hood body, and the lower end of the exhaust pipe is connected with the exhaust purification device; the hood body comprises a hood shell, a neck limiting sealing belt, a shoulder and chest lower hem, a fixing belt of the shoulder and chest lower hem, a face transparent elastic air bag, an oxygen inlet pipe and two side transparent elastic air storage bags, the shell is supported at the periphery of the head of a transferred patient; the face elastic transparent air bag and the two side elastic transparent air storage bags are made of elastic thin film materials. The face elastic transparent air bags are positioned in front of eyes of the transshipment patient; the two lateral elastic transparent air storage bags are located on the outer sides of two ears of the transshipment patient respectively. When the patient wears the negative pressure hood and starts the air exhaust purification device to exhaust and filter air in the negative pressure hood, negative pressure can be kept in the negative pressure hood, and the negative pressure condition in the negative pressure hood can be displayed according to the sunken degree of elastic films of the face elastic transparent air bags and the two side elastic transparent air storage bags. The isolation effect is good, and the transfer cost is low.

Description

technical field [0001] The invention relates to the field of medical protective articles, in particular to a negative pressure headgear used for transporting patients with respiratory infectious diseases. Background technique [0002] As we all know, the recent new type of coronavirus can be described as sweeping the world, together with the previous SARS and Ebola, it can be said that such a severe infectious disease has become more and more severe in recent years, which not only seriously affects people's production and life, but also affects people's lives. Front-line medical staff pose a great risk, and it can even spread from person to person through droplets and aerosols. Therefore, the transfer of patients with this respiratory infectious disease must be extremely strict to avoid infection of close contacts. At present, the transfer of patients with this respiratory infectious disease is mainly completed by masks and negative pressure cabins, so as to prevent the pat...

Problems solved by technology

The tidal fluctuation of the gas demand in the hood during exhalation and inhalation and its challenge to maintain the internal negative pressure at all times. Excessive airflow is not easy to lose the internal negative pressure but it is uncomfortable to blow, and it also shortens the battery life of the device. Real-time Barometer monitoring is complex and unreliable
