Problems solved by technology

[0002] The existing general medical sputum suction device includes a suction tube and a negative pressure air bag. The negative pressure air bag has small pressure and small suction, and the negative pressure of the negative pressure air bag is not easy to control.
When the negative pressure airbag is used, there may be a backflow phenomenon, and it is very inconvenient to clean at the same time
The sputum suction tube is relatively smooth, and the doctor can’t use his wrist to suck phlegm. There is no scale on the sputum suction tube, and the doctor is not accurate when placing the length of the sputum suction tube to the patient’s throat.

Embodiment Construction

[0013] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises a sputum suction tube 1 and a piston 2, and a sputum container 3 with a cover 4 is arranged between the sputum suction tube 1 and the piston 2, so when cleaning the sputum container 3, open the cover 4 and pour the sputum into the garbage cylinder, and then clean the expectorant 3. The sputum suction tube 1, the piston 2 and the sputum holder 3 are connected through a three-way pipe 5. The sputum holder 3 and the piston 2 are respectively provided with a one-way valve 6 near the three-way pipe 5, and the piston 2 is connected with a negative pressure gauge 7. The sputum suction tube 1 is provided with anti-slip lines 8 and a scale 9 . The anti-splash mask 10 is provided with a hole adapted to the sputum suction tube 1, and the anti-splash mask 10 is sleeved on the sputum suction tube 1 through the hole thereon.

[0014] Slide the anti-splash mask 10 during use, pu...

Abstract

The invention relates to a medical appliance, in particular to a medical sputum aspirator. The medical sputum aspirator comprises a suction catheter and a piston and is characterized in that: a sputum accommodating container with a cover is arranged between the suction catheter and the piston; the suction catheter, the piston and the sputum accommodating container are connected with one another though a three-way pipe; the sputum accommodating container and the piston, which are close to the three-way pipe, are respectively provided with a one-way valve; and the piston is connected with a negative pressure meter. Therefore, the medical sputum aspirator has the advantages of simple structure, large suction, convenient cleaning and accurate pressure.

Description

(1) Technical field [0001] The invention relates to a medical appliance, in particular to a medical phlegm suction device. (2) Background technology [0002] Existing common medical sputum suction device comprises sputum suction tube and negative pressure air bag, and negative pressure air bag pressure is little, and suction is also little, and the negative pressure size of this negative pressure air bag is also difficult to grasp. When the negative pressure airbag is in use, backflow may also occur, and cleaning is also very inconvenient. The sputum suction tube is relatively smooth, and the doctor's wrist does not need to be strong when sucking sputum. There is no scale on the sputum suction tube, and the doctor is inaccurate when placing the length of the sputum suction tube on the patient's throat. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a medical sputum suction device with strong...
