Embodiment 1

[0022] Embodiment 1, a kind of oral and nasal secretion suction device, such as figure 1 As shown, it includes a sputum suction tube 2, and a negative pressure unit 1 is connected to the rear end of the sputum suction tube 2, and the negative pressure unit 1 can make the sputum suction tube 2 suck and discharge secretions in the mouth and nose.

[0023] The negative pressure unit 1 includes a shell 1-1 communicated with the sputum suction tube 2, a piston 1-2 is arranged inside the shell 1-1, a piston rod 1-5 is connected to the rear center of the piston 1-2, the piston 1 -2 Divide the inner chamber of the shell 1-1 into a rod chamber 1-3 and a rodless chamber 1-4, the rear end of the suction tube 2 communicates with the rodless chamber 1-4, and the rodless chamber 1-4 connects with the suction chamber A first one-way valve 4 is arranged between the sputum tubes 2, and a second one-way valve 5 is arranged on the side walls of the rodless chambers 1-4. The first one-way valve ...

Embodiment 2

[0030]Embodiment 2, a kind of oral and nasal secretion suction device, such as figure 1 As shown, the outer side of the housing 1-1 is provided with a fixed handle 1-7, and the fixed handle 1-7 is hinged with a movable handle 1-6 inserted into the housing 1-1. The rear ends of the rods 1-5 are hinged. When the operator holds the movable handle 1-6 and rotates relative to the fixed handle 1-7, the movable handle 1-6 will drive the piston rod 1-5 to move, and then drive the piston 1-2 to move in the shell 1-1, thereby realizing a single Negative pressure is formed by hand operation, and the operation is very convenient.

[0031] Specifically, the rear end of the piston rod 1-5 is provided with a pin shaft 1-8, and one end of the movable handle 1-6 protruding into the housing 1-1 is provided with a long hole 1-9 which is slidingly and hingedly fitted with the pin shaft. The operator can discharge the air in the rodless cavity 1-4 by reciprocatingly pressing the movable handle 1...

Abstract

The invention discloses a mouth and nose secretion suction device. The technical problems that an existing sputum suction bag has cross contamination and easily damages the nasal mucosa or the oral mucosa are solved. The mouth and nose secretion suction device comprises a sputum suction tube, wherein the rear end of the sputum suction tube is connected with a negative pressure unit; the front endof the sputum suction tube is connected with a mouth and nose suction device; the middle of the sputum suction tube is detachably connected with a drainage tank or a drainage bag; the mouth and nose suction device comprises a handheld bin; the front end of the handheld bin is connected with a flexible suction end; the rear end of the handheld bin is communicated with the sputum suction tube; the front end of the handheld bin is communicated with the outside through the suction end; and a side hole is formed in one side of the handheld bin. The mouth and nose secretion suction device is convenient to operate, the negative pressure is easy to control, and cross contamination and damage to the nasal mucosa or the oral mucosa can be avoided.

Description

technical field [0001] The invention belongs to the technical field of clinical suction of secretions, in particular to an oral and nasal secretion suction device. Background technique [0002] The disposable sputum aspirator bag clinically used at present includes a sputum suction tube and a sterile glove for disposable use. During use, it is necessary to suck the oral secretions first, and then the nasal secretions, or first suck the secretions of the intubation tube, and then suck the oral and nasal secretions. In order to avoid contamination of the sputum suction tube after the first suction, and another suction, the sputum suction tube contaminated by the first suction of secretions will be polluted again, so it is required to first suction the parts that require a higher degree of cleanliness. Even so, the oral cavity and / or nasal cavity have to be forced to use the polluted sputum suction tube to suction again, which is likely to cause cross-contamination. [0003] ...
