Manual sputum aspirator

Abstract

The invention discloses a manual sputum aspirator, comprising a piston assembly, a transition tube and a sputum suction tube, wherein one end of the transition tube is connected with the sputum suction tube while the other end thereof is connected with the piston assembly in sealing; the piston assembly comprises a piston shell, a hand-held handle, a piston and a connecting rod; the hand-held handle is connected with the piston through the connecting rod; a pulley element is respectively arranged in two contact planes of the hand-held handle and the piston shell; the middle part of the transition tube is downward sunken into a 'V-shaped' tube, a sputum-obstructing plate is arranged in an oblique plane of the inner tube surface of the 'V-shaped' tube, and the inner tube surface is adjacent to one end of the piston; the bottom of the 'V-shaped' tube is connected with a branched tube on which a sputum-collecting bottle is connected in sealing. The manual sputum aspirator is simple in structural design and convenient to operate; various parts are easy to disassemble and assemble and convenient to clean and disinfect, and thus the manual sputum aspirator has a good sputum collecting effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a manual sputum suction device. Background technique [0002] In the process of clinical nursing, many patients cannot expectorate sputum on their own and need artificial suction to keep the airway open. Electric sputum suction devices are generally used in clinical care and first aid in hospitals, which are not only expensive, cumbersome and inconvenient to carry, but more seriously, they must rely on power to work, which brings inconvenience to outdoor rescue and is not suitable for widespread use. The existing manual sputum suction device is generally designed with a negative pressure system, which has no energy consumption, no noise, and is dedicated to a special person, which can avoid cross-infection and is safe to use. And it is not easy to clean and disinfect, which increases the labor intensity of nursing staff. SUMMARY OF THE INVENTION [0003] I...

Problems solved by technology

Electric sputum suction devices are generally used in hospital clinical care and first aid. Not only are they expensive, bulky and inconvenient to carry, but more seriously, they must rely on power to work, which brings inconvenience to outdoor rescue and is not suitable for widespread use. However, the existing manual sputum suction devices are generally designed with a negative pressure system, which has no energy consumption and noise, and is dedicated to special personnel, which can avoid cross-infection and is safe to use. However, the existing manual sputum suction devices have complex structures and poor sputum collection effects. And it is not easy to clean and disinfect, which increases the labor intensity of nursing staff
