Abstract
The utility model discloses a manual operate sputum aspirator, comprising a gasbag, a triple valve connected with the air inlet and outlet of the gasbag, a sputum aspirating tube connected with one outlet of the triple valve by a one-way valve, and a sputum discharging tube connected with the other outlet of the triple valve by a one-way valve. When the utility model is used, the sputum aspirating tube is inserted into throat of patient, and the sputum discharging tube is connected with a plastic bag or a spittoon. When the gasbag is extruded, the one-way valve connected with the sputum aspirating tube is closed and the one-way valve connected with the sputum discharging tube is opened, thus the air in gasbag can be discharged via the sputum discharging tube; when the gasbag is loosened, the gasbag generates a negative pressure due to intrinsic elastic force, simultaneously the one-way valve connected with the sputum aspirating tube is opened and the one-way valve connected with the sputum discharging tube is closed, thus the sputum is aspirated into the gasbag via the sputum aspirating tube; when the gasbag is extruded again, the sputum is discharged via the sputum discharging tube. The utility model has simple structure, disposability and great social benefit.
Description
Technical field
This utility model relates to a kind of sputum aspirator.
Background technology
The sputum aspirator that uses mostly is electronic now, and its shortcoming is: 1, volume is bigger, is not easy to move; 2 and cost higher, be not easy to apply, especially can not use in the family, the patient's who is in to bed nursing brings very big inconvenience; 3, many people reuse, and cause cross infection easily.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, manually actuated sputum aspirator.
For achieving the above object, the technical solution of the utility model is: manually sputum aspirator comprises that an outlet of air bag, the three-way valve that is connected with the air bag air inlet/outlet, three-way valve is connected with sputum aspirator tube by check valve, and another outlet of three-way valve is connected with the expectoration pipe by check valve.
Owing to adopt technique scheme, manually sputum aspirator comprises that an outlet of air bag, the three-way valve that is connected with the air bag air inlet/outlet, three-way valve is connected with sputum aspirator tube by check valve, and another outlet of three-way valve is connected with the expectoration pipe by check valve.Like this, when people use, sputum aspirator tube is inserted patient throat, external plastic bag of expectoration pipe or spittoon, extruding gasbag, the check valve that be connected with sputum aspirator tube this moment ends, and with the one-way valve opens that the expectoration pipe is connected, air goes out by the expectoration bank of tubes in the air bag; Unclamp air bag, air bag is because self elastic force produces negative pressure, the one-way valve opens that be connected with sputum aspirator tube this moment, and the check valve that is connected with the expectoration pipe ends, and sputum is inhaled in the air bag by sputum aspirator tube; Extruding gasbag once more, then sputum goes out by the expectoration bank of tubes.This utility model is simple in structure, can be used as disposable products uses, and has great social benefit.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment
As shown in drawings, manually sputum aspirator comprises that an outlet of air bag 1, the three-way valve 2 that is connected with air bag 1 air inlet/outlet, three-way valve 2 is connected with sputum aspirator tube 4 by check valve 21, and another outlet of three-way valve 2 is connected with expectoration pipe 3 by check valve 22.
During use, sputum aspirator tube 4 is inserted patient throat, expectoration pipe 3 an external plastic bag or spittoons, extruding gasbag 1, the check valve 21 that be connected with sputum aspirator tube 4 this moment ends, and the check valve 22 that is connected with expectoration pipe 3 is opened, and air is discharged by expectoration pipe 3 in the air bag 1; Unclamp air bag 1, air bag 1 is because self elastic force produces negative pressure, and the check valve 21 that be connected with sputum aspirator tube 4 this moment is opened, and the check valve 22 that is connected with expectoration pipe 3 ends, and sputum is inhaled in the air bag 1 by sputum aspirator tube 4; Extruding gasbag 1 once more, and then sputum is discharged by expectoration pipe 3.This utility model is simple in structure, can be used as disposable products uses, and has great social benefit.
