Sputum suction device

Abstract

The invention relates to the field of medical devices, in particular to a sputum suction device which comprises a machine body, a sputum storage bottle, an air filter, a negative pressure pump, a vacuum meter for detecting negative pressure value, a vacuum pump, a silencer, a negative pressure adjusting valve, a dual-station reversing valve, a three-way valve, an oxygen pipe, a sputum suction pipe and a trachea sleeve. The silencer is connected with an exhaust opening of the vacuum pump. The air filter is connected with an air suction opening of the vacuum pump. The air filter, the sputum storage bottle, the negative pressure adjusting valve, the dual-station reversing valve and the three-way valve are sequentially connected in series from left to right. Disinfectant is contained in the sputum storage bottle. The trachea sleeve is connected with the outlet end of the three-way valve through the oxygen pipe. The sputum suction pipe does not need to be manually pulled out, the damage to the respiratory mucosa of a patient by insufficient personal experience or misoperation can be avoided, the trachea sleeve can be well fixed in a trachea through an inner air bag so that disengagement can be prevented, and through the combination of an outer air bag and a medicine applying pipe, medicine applying and sputum suction at the position of the air bags can be achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a sputum suction device. Background technique [0002] Aspiration method (aspiration n of sputum) refers to a method of sucking out respiratory secretions through the mouth, nasal cavity, and artificial airway to keep the airway unobstructed and prevent complications such as aspiration pneumonia, atelectasis, and suffocation. Clinically, it is mainly used for those who cannot effectively cough and expectorate due to various reasons, such as the elderly, infirm, critically ill, coma, and before anesthesia. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a sputum suction device, which does not need to manually pull out the sputum suction tube, and can avoid damage to the patient's suction tract mucosa due to insufficient manual experience or operational errors.

Problems solved by technology

[0003] The present invention aims to solve the above problems, and provides a sputum suction device, which does not need to manually pull out the sputum suction tube, and can avoid damage to the patient's suction tract mucosa due to insufficient manual experience or operational errors. The airbag can be well fixed in the trachea to prevent loosening, and the outer airbag combined with the medicine tube can be used to apply medicine and absorb sputum at the airbag. The technical scheme adopted is as follows:
