A sputum suction device for emergency department

Abstract

The invention relates to a sputum suction device in the emergency department, which comprises a casing, on which there is a handle and a pull ring, and the pull ring slides horizontally with the casing and is connected via a first spring; there is a vertical end face cam on the casing, The end face cam is connected with the pull ring through the crank linkage mechanism; there are multiple vertical piston barrels on the housing, and there are pistons and piston push rods in the piston barrels; one end of the piston push rod is connected with the piston, and the other end is in contact with the end face cam; the piston There is a second spring on the push rod to make it reset; there is an air intake channel and an exhaust channel with a duckbill valve on the piston barrel; there is a Venturi tube on the housing, and multiple exhaust channels are connected to the Venturi tube at the same time; It also includes a sputum suction tube, a sputum collection tank and a three-way joint. The sputum suction tube is composed of an outer tube and an inner tube. The two ends of the outer tube are connected to the inner tube. One end of the outer tube is a bellows structure. The scraper sleeve on the periphery of the corrugated tube has a number of suction holes on the outer tube; the three-way joint is connected with the sputum collection tank, the outer tube and the Venturi tube through flexible tubes.

Description

technical field [0001] The invention relates to emergency medical equipment, in particular to an emergency sputum suction device. Background technique [0002] In the process of emergency treatment, some emergency patients often encounter the problem of mucus blocking the airway due to various reasons, resulting in dyspnea. In this case, it is necessary to suck out the mucus in the patient's body as soon as possible to ensure normal breathing and prevent suffocation. Therefore, the emergency department usually has a sputum aspirator; however, the existing sputum aspirators are mainly electric multifunctional negative pressure sputum aspirators and simple manual sputum aspirators. It is more convenient to use in the consulting room. Once there is a power failure or when going out for first aid, it will be unusable, which will bring inconvenience to the rescue work; the simple manual sputum suction device does not need energy to drive, and uses the piston movement to achieve t...
