Lung clearing and sputum excretion device for respiratory medicine department

Abstract

The invention discloses a lung clearing and sputum excretion device for the respiratory medicine department. The device comprises a body; a sputum conveying tube is installed on the inner side face of the body; a fixed base is welded to the outer surface of the sputum conveying tube; a connecting base is installed at the end, away from the body, of the sputum conveying tube; a sputum suction tube is installed on the side, away from the sputum conveying tube, of the connecting base; a through hole is formed in the end, away from the connecting base, of the sputum suction tube; a first cavity is formed in the body; an inclined plate is installed on the lower end face of the first cavity; a built-in thread is formed in the side, away from the inclined plate, of the body; a locking piece is installed on the side, away from the body, of the built-in thread; a collecting box is installed on the inner side face of the locking piece; a first installing block is installed on the side, away from the sputum conveying tube, of the first cavity; and medical cotton is installed on the inner side surface of the first installing block. According to the invention, a medical staff can clean the device conveniently; a fixing device is arranged, so that the medical staff can move the sputum excretion device conveniently, and the working difficulty of the medical staff is lowered; and meanwhile a protecting piece is installed, so that the device can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lung-clearing and phlegm-expelling device for respiratory medicine. Background technique [0002] Respiratory diseases are common and frequently-occurring diseases of human beings. The mucous glands and goblet cells of the human trachea and bronchi often secrete liquid to moisten mucous membranes and adhere to dust and microorganisms in the air. If sputum retention will promote the reproduction of microorganisms in the respiratory tract, the growth will cause harm to the body and cause disease exacerbation, aggravation of infection. [0003] The traditional sputum removal device needs to replace the entire sputum suction tube after use. Since the sputum suction tube is directly connected to the main body, frequent replacement will cause a gap between the sputum suction tube and the main body, affecting the first cavity At the same time, when the negative pressure stru...

AI Technical Summary

Problems solved by technology

[0003] The traditional sputum removal device needs to replace the entire sputum suction tube after use. Since the sputum suction tube is directly connected to the main body, frequent replacement will cause a gap between the sputum suction tube and the main body, affecting the first cavity At the same time, when the negative pressure structure on the sputum discharge device extracts the air in the first cavity, due to the excessive power of the negative pressure fan, the sputum will be sucked into the negative pressure structure, causing damage to the negative pressure structure. Moreover, the inside of the sputum discharge device is not easy to clean, and there is also the problem that the sputum delivery tube will shake back and forth when the medical staff moves the sputum discharge device after the patient has used the sputum discharge device
