Sputum aspirator for emergency use in the Department of Respiratory Medicine

Abstract

The invention relates to the field of medical apparatus and instruments, and particularly relates to a sputum aspirator for emergency use in the Department of Respiratory Medicine. The sputum aspirator comprises a shell body and a handle member arranged on the lower side of the shell body, a piston member is arranged in the shell body, a fixing block is connected to the right side of the shell body in a clamped mode, baffles are glued on the middle of the inner wall of the shell body in front-back symmetry connection, the piston member is fixed between the fixing block and the baffles in clamped connection, the right side of the piston member is provided with an air outlet, the right end of the air outlet is connected with a three-way air-guide tube in a interference fit mode, the right end and the middle part of the three-way air-guide tube are provided with a one-way rubber exhaust nozzle and a one-way rubber vacuum nozzle, respectively, the left end of the three-way air-guide tube is in glued connection with a screw cap, the screw cap is fixedly connected to the left side of the shell body through first clamping arms which are symmetrically arranged, and the lower side of the screw cap is spirally connected with a phlegm storing bottle. The invention is not only simple in structure, low in production cost, small and exquisite in structure, easy to carry and use, easy to disassemble and clean and convenient for secondary use, but also capable of avoiding the return of some phlegm to patient's body resulted from repeated pressing, thereby improving the efficiency of phlegmremoval.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an emergency sputum suction device for respiratory medicine. Background technique [0002] Respiratory medicine, medical staff checks the patient for phlegm in the throat, and urgently clears the phlegm for the patient, otherwise the patient has difficulty breathing, which may endanger the patient's life in severe cases. Usually, severe patients or comatose patients have phlegm and cannot cough it out on their own , At this time, it is necessary to use a sputum suction device to help the patient suck out the sputum. [0003] Usually, the sputum suction device adopts the principle of negative pressure. One is to use an air pump type to suck out the sputum in the throat through a catheter; the other is to use a piston type to suck out the sputum in the throat by pulling the piston rod. However, the air suction pump type has a large footprint, is not easy to carry, is inconvenient ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides an emergency sputum aspirator for respiratory medicine, which can effectively solve the problem of adopting the air suction pump type in the prior art. Inconvenient, and the production cost is high. If the piston type is used, part of the sputum will return to the patient's body after repeated pulling, resulting in low efficiency of sputum removal. At the same time, the pump type and the piston type are not suitable for disassembly and cleaning, which will affect the suction The problem of the secondary use of the device
