Sputum suction device for internal medicine nursing

Abstract

A sputum suction device for internal medicine nursing comprises an upper tooth socket, a hose, a liquid injection tank, an air suction tank and a lower tooth socket, a breathing groove penetrates through the interior of the hose, an annular air bag is connected to the bottom of the hose, and a through hole is formed in the inner side of the annular air bag. By arranging the liquid injection tank and the air suction tank which are consistent in height and inconsistent in volume and arranging the liquid injection groove and the sputum suction pipe on the hose which are communicated with the liquid injection tank and the air suction tank respectively, in the sputum suction process, conveniently the extrusion head is extruded in a reciprocating mode to generate conveying force on cleaning liquid and absorbing force on sputum at the same time, operation is convenient. Lifting and resetting of the extrusion head are achieved through the reset spring, manpower is saved, the volume differencebetween the liquid injection tank and the air suction tank is used for generating a powerful sputum suction effect, the flow speed of air in the sputum suction opening and the sputum suction pipe is higher than that in the liquid injection groove and the liquid spraying hole, suction force is larger, and the sputum suction cleanliness is improved; accumulated liquid or sputum backflow in the sputum suction process is avoided, and the sputum suction effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sputum suction device for internal medicine nursing. Background technique [0002] Internal medicine patients may have sputum that cannot be coughed out on their own, and sputum suction requires professional nursing staff. For patients with phlegm, nurses need to perform sputum suction multiple times in a short period of time, or even at regular intervals. Phlegm operation, and when the patient's sputum is relatively viscous, which makes it difficult to suck out the sputum, it is necessary to inject a certain amount of normal saline into the patient's respiratory tract. The sputum suction tube will also cause damage to the patient's respiratory tract, and the injection of normal saline will easily cause the normal saline to drive the sputum down together, affecting the suction effect of the sputum. [0003] At present, the existing sputum suction device has simple stru...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sputum suction device for internal medicine nursing to solve the problem that the existing sputum suction device proposed in the above background technology has simple structure, complicated operation, low sputum suction efficiency, increased sputum suction time, and increased patient pain. It is difficult to control the suction force of sputum during the suction process, and it is easy to cause damage between the pipeline and the patient's esophagus during the suction process. , it is easy to absorb dirty, and it is easy to produce fluid accumulation after absorption
