An easy-to-clean manual sputum suction device

Abstract

The invention discloses a sputum aspirator convenient to clean. The sputum aspirator comprises a suction pipe, a connection pipe and a sputum collection bottle, wherein a multi-layer cone head I is fixed at the end, away from the suction pipe, of the connection pipe, and the multi-layer cone head I is movably connected with a sputum collection pipe; a multi-layer cone head II is communicated withthe sputum collection bottle through a communication port, and a garbage bag is arranged in the sputum collection bottle; extrusion springs are symmetrically arranged in a flow limit block; the sputumcollection pipe is movably arranged between the extrusion springs; the extrusion springs are connected to an extrusion plate which is fixedly connected with a push rod; limit rods are symmetrically fixed on the side, close to a through hole, of a baffle block; each limit rod comprises an outer rod and an inner rod, and the outer rod is provided with an outer rod inner cavity; grooves are formed in fixing blocks, and springs are arranged in the grooves. The sputum aspirator convenient to clean can be cleaned and disinfected wholly, reassembly after dismounting and cleaning is not needed, and the sputum aspirator is simple to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sputum aspirators, in particular to a manual sputum aspirator that is easy to clean. Background technique [0002] The sputum suction device is a common instrument in respiratory medicine. It is of great significance to keep the patient's airway unobstructed, prevent suffocation, remove airway secretions, and reduce lung infection. At present, most wards of the hospital are generally equipped with a central negative pressure suction interface. However, in some auxiliary departments, there is often no central negative pressure interface, and electric sputum aspirators can only be used for sputum suction, and electric sputum aspirators rely on fixed power sources, and are large in size and difficult to carry. In most cases, it is necessary to rely on the manual sputum suction device. The existing manual sputum suction device has a complicated structure and cannot be cleaned as a whole, or it needs to be dis...

AI Technical Summary

Problems solved by technology

[0004] However, there are still obvious defects in its use: the inner cavity of the sputum suction device and the sputum collection bottle are not easy to clean, and if it is cleaned by disassembling part by part, it will be cumbersome to reassemble; if alcohol is sucked through the sputum suction tube, etc. If the cleaning solution is used for overall cleaning and disinfection, the disinfectant will flow directly into the sputum collection bottle and cannot clean the suction port and the suction tube. If there is dirt in the suction port and the suction tube, it will be difficult to clean, resulting in insufficient cleaning and pollution Hidden danger, easy to breed bacteria
