Pedal type sputum suction device

Abstract

The invention relates to the field of medical instruments, in particular to a foot-stepping type sputum suction device which comprises a fixed bottom plate, two rotating supports which are symmetrically distributed are fixedly installed on the fixed bottom plate, a rotating pedal is rotatably installed between the two rotating supports, and a plurality of movable inserting grooves are formed in the rotating pedal in a linear distribution mode. The two ends of the movable inserting groove penetrate through the rotating pedal, and a movable inserting rod is inserted into the movable inserting groove. When an existing manual sputum aspirator sucks sputum, manual pressing is generally needed to drive a piston to move to generate suction force, when a silica gel hose is inserted into the trachea of a patient, manual force exerting can cause the silica gel hose to shake and touch the trachea of the patient, and after the trachea of the patient is touched, the patient generates body reaction. And the use stability is poor. According to the manual sputum aspirator, the piston can be driven to move to generate suction force through force generated by the feet, shaking caused by force generated by the hands of a user is avoided, and the problem that an existing manual sputum aspirator is poor in stability when used is solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a foot-stepped sputum suction device. Background technique [0002] A sputum suction device is a device used to absorb the sputum accumulated in the trachea of ​​a patient. It belongs to a kind of medical device. It is generally divided into an electric sputum suction device and a manual sputum suction device. It drives the piston movement to generate suction, and then inserts one end of the silicone hose pre-connected to the suction device into the patient's trachea and contacts the accumulated sputum. The suction generated by the piston movement sucks the accumulated sputum into the suction device. . [0003] At present, most of the manual sputum suction devices are used at home, which can accurately grasp the position, adjust the suction force or terminate the suction force in time, and the use method is simple and easy to operate. When the silicone hose is inserted into t...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the manual sputum suction devices are used in households, which can accurately grasp the position, adjust the suction force or stop the suction force in time, and the method of use is simple and easy to operate. Generally, manual pressing is required to drive the piston to generate suction. When the silicone hose is inserted into the patient's trachea, artificial force will cause the silicone hose to shake and touch the patient's trachea. Response, at this time, the silicone hose inserted into the patient's trachea is likely to cause damage to the patient's trachea, and its use stability is poor. Multiple operations are required to achieve the purpose, which reduces the efficiency of manual sputum suction and increases the patient's discomfort due to sputum suction
