Rapid lung-heat-clearing sputum excretion device for respiratory medicine nursing

Abstract

The invention provides a rapid lung-heat-clearing sputum excretion device for respiratory medicine nursing, relates to the technical field of medical instruments, and solves the problems that adsorption type fixation cannot be realized through structural improvement, and elastic locking of an air suction structure and drawing limiting of the air suction structure cannot be achieved through structural improvement. The rapid lung-heat-clearing sputum excretion device for respiratory medicine nursing comprises a collecting barrel; the collecting barrel is connected with the air suction structure;and an auxiliary structure is installed on the air suction structure. An elastic telescopic rod is welded to the tail end of a connecting rod, and the head end of the elastic telescopic rod is of anarc-shaped structure; The head end of the elastic telescopic rod is connected with a clamping groove in a clamped mode, the elastic telescopic rod and the clamping groove jointly form an elastic locking structure of a piston rod, and when the piston rod moves leftwards by 20 cm, the elastic telescopic rod makes contact with a handle of a piston pipe, so that on one hand, backflow of the piston rodunder the negative pressure effect of the lung can be prevented through elastic locking, and on the other hand, the elastic telescopic rod can also realize drawing limiting of the piston rod.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and more specifically relates to a rapid lung-clearing and expectorant-expelling device for respiratory internal medicine nursing. Background technique [0002] Sputum suction is a method of using the principle of negative pressure suction to remove secretions in the respiratory tract through the mouth, nose or artificial airway with a catheter to keep the respiratory tract unobstructed, and the purpose of suctioning is to remove respiratory secretions and keep the respiratory tract unobstructed , prevent aspiration pneumonia, atelectasis, suffocation and other complications, promote respiratory function, and improve lung ventilation. In the nursing process of respiratory medicine, sputum suction is a common operation. [0003] For example, the application number: CN201921372624.0, this utility model provides a lung clearing and expectorant device for respiratory medicine nursing. The ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a fast lung-clearing and sputum-expelling device for respiratory medical care to solve the existing problem that the sealing ring installed on the barrel body of the existing device is easy to fall off, and cannot pass through the structure. Improvement to achieve adsorption fixation; moreover, after suction is completed, under the action of lung negative pressure, it is easy to cause reflux in the inspiratory structure, and it is impossible to achieve elastic locking of the inspiratory structure through structural improvement, and The problem of the extraction limit of the suction structure
