Portable sputum aspirator

Abstract

The invention relates to a portable sputum aspirator. The sputum aspirator comprises a machine body, a liquid storage bottle, a safety bottle and an air pump are arranged on the machine body, and theupper end surface of the liquid storage bottle is respectively connected with a liquid inlet pipe and an exhaust pipe, the upper end of the liquid inlet pipe is connected with a sputum suction hose, the upper end of the exhaust pipe is connected to an air inlet pipe connected to the upper end surface of the safety bottle through a connecting pipe, and the part, located on one side of the air inletpipe, of the upper end surface of the safety bottle is provided with an air suction pipe, the air suction pipe is connected with the air pump through a connecting pipe, a funnel-shaped protective cover is arranged in the part, located below the exhaust pipe, of the liquid storage bottle, the bottom end surface of the protective cover is provided with a filter plate, and the liquid inlet pipe, theexhaust pipe, the air inlet pipe and the air suction pipe are provided with pipe stoppers near the upper ends. In general, the sputum aspirator has the advantages of having reasonable structure design and being capable of effectively preventing secondary pollution of sputum in the sputum aspirator.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a portable sputum suction device. Background technique [0002] For critically ill patients, due to the inability to cough up sputum, sputum can easily block the respiratory tract and endanger life safety. At this time, it is one of the important ways for patients to get out of life danger as soon as possible by using a sputum suction device. It generally includes a disposable sputum collection tube. The sputum collection tube is connected with a soft suction tube and a suction tube. The suction tube is connected to a negative pressure source. The sputum is sucked into the tube body by the suction tube. , the viscous sputum is easily splashed to the back end of the trachea by the suction of the trachea, or the suction tube is deflected toward the back end of the trachea by suction, thereby blocking the trachea, causing equipment failure, affecting normal opera...

[0002] For critically ill patients, due to the inability to cough up sputum, sputum can easily block the respiratory tract and endanger life safety. At this time, it is one of the important ways for patients to get out of life danger as soon as possible by using a sputum suction device. It generally includes a disposable sputum collection tube. The sputum collection tube is connected with a soft suction tube and a suction tube. The suction tube is connected to a negative pressure source. The sputum is sucked into the tube body by the suction tube. , the viscous sputum is easily splashed to the back end of the trachea by the suction of the trachea, or the suction tube is deflected toward the back end of the trachea by suction, thereby blocking the trachea, causing equipment failure, affecting normal operation, and increasing the pain of the patient. The tube body is dumped, and the sputum in the tube is easy to flow out of the tube, thereby polluting the surrounding medical environment; therefore, a portable device with a reasonable structure design that can effectively prevent the secondary pollution of the sputum in the sputum suction device is provided. Aspirator is very necessary
