Background technique

At present, environmental pollution is increasing day by day, and there are more and more patients with respiratory medical diseases, especially coughs are the most frequent attacks. In the middle stage of the cough, there is a lot of phlegm, which blocks the patient's trachea, affects vocalization, eating, breathing, etc., and brings discomfort to the patient. Some long-term bedridden patients, the infirm, young children and other people cannot cough up the sputum by themselves and need to use sputum suction. The device is used for manual suction of sputum, and all components of the existing disposable sputum suction device are polluted after use, resulting in serious waste.

Therefore, the sputum suction device of the prior art is provided with an air filter between the sputum collection tank and the suction mechanism. However, after the air filter has filtered the sputum for many times, the filter holes will inevitably be blocked, which hinders the airflow from collecting sputum. Continuity of tank flow to the pumping mechanism.

The phlegm-inducing part includes a sputum suction tube 7, a first one-way valve 8 and a second one-way valve 9, one end of the sputum suction tube 7 is connected to the sputum suction mouth 20, and the other end is connected to the first one-way valve. The inlet 15 of the valve 8, the outlet 16 of the first one-way valve 8 is connected to the top wall of the tank 1, the inlet 15 of the second one-way valve 9 is connected to the side wall of the tank 1, The outlet 16 of the second one-way valve 9 communicates with the external environment;

Wherein, the outlet 16 of the first one-way valve 8 and the inlet 15 of the second one-way valve 9 are respectively connected to the parts of the tank body 1 outside the filtering space.

Nursing sputum suction device works as follows:

When it is necessary to suck sputum from the patient's respiratory tract, one end of the sputum suction tube 7 is inserted into the patient's airway, and the piston rod 6 is pushed and pulled to drive the piston 5 to reciprocate in the barrel 4 .

During the reciprocating movement of the piston 5, when the piston 5 moves away from the first side wall, the distance between the piston 5 and the first side wall expands, a negative pressure space is formed in the cylinder body 4, and the air in the tank body 1 enters through the air pipe 3 The cylinder 4, the first one-way valve 8 is opened, and the sputum in the suction tube 7 passes through the first one-way valve 8 and enters the tank 1. Due to the blocking effect of the air filter 2, the sputum components cannot pass through the air. The filter sheet 2 is deposited on the lower part of the tank body 1, and the air in the tank body 1 passes through the air filter sheet 2 forwardly.

When the piston 5 is close to the first side wall, the distance between the piston 5 and the first side wall is reduced, the air in the barrel 4 flows back into the tank 1, the second one-way valve 9 is opened, and the air in the tank 1 Exhaust to the external environment. During the above-mentioned air backflow process, the air reversely passes through the air filter 2 to blow off the sputum components attached to the air filter 2 to prevent the sputum components from clogging the filter holes on the air filter 2 .

In the technical solution of the present utility model, through the above process, since the air filter 2 is periodically blown forward and back by the air, the filter holes on the air filter 2 will not be blocked, and the gap between the tank body 1 and the cylinder body 4 will not be blocked. There can be a continuous airflow between them, so the strength of the forward-flowing airflow will not weaken, thereby ensuring that the strength of sucking sputum in the sputum suction tube 7 will not be weakened.

Specifically, the reciprocating motion of the piston 5 matches the breathing of the patient. When the patient inhales, the piston 5 moves toward the direction close to the first side wall, the first one-way valve 8 is not opened, and the sputum in the suction tube 7 is not sucked out. to the tank body 1; when the patient exhales, the piston 5 moves away from the first side wall, and the first one-way valve 8 is opened (atmospheric pressure in the human trachea 3, negative pressure in the tank body 1, the first one-way valve The pressure at the inlet 15 of the valve 8 is greater than the pressure at the outlet 16 of the first one-way valve 8, so the first one-way valve 8 is opened), and the sputum in the trachea 3 flows out to the tank body 1 through the sputum suction tube 7.

As shown in Figure 2 and Figure 3, in a specific embodiment, it also includes a cleaning pipe 10, the air filter 2 has an arc surface, and one side of the air filter 2 is connected to the tank body 1 The top wall, the other side is connected to the side wall of the tank 1, the cleaning pipe 10 is connected to the top wall of the tank 1, and the cleaning pipe 10 is along the arc of the upper surface of the air filter 2 extend in the tangential direction of the shape.

The upper surface of the sheet 2 flows downwards, and passes through each filter hole in reverse order, and finally deposits at the bottom of the tank body 1 to strip the sputum components that block the filter holes.

Specifically, the cleaning pipe 10 is provided with a control valve 11 for controlling the addition of cleaning liquid.

As shown in Figure 5, in a specific embodiment, the structure of the first one-way valve 8 and the second one-way valve 9 are the same, both including a housing 12, a valve core block 13 and a spring 14, the inlet 15 is located at one end of the housing 12, the outlet 16 is located at the axial side of the housing 12, the spring 14 is arranged between the valve core block 13 and the other end of the housing 12, the valve The diameter of the pellet 13 is larger than the inner diameter of the inlet 15 .

In this embodiment, specifically, when the air pressure at the inlet 15 of the one-way valve is greater than the air pressure at the outlet 16 of the one-way valve, an air pressure difference is formed, and the pressure difference drives the valve core block 13 to overcome the elastic force of the spring 14 to the other side of the housing 12. One end moves, the valve core block 13 is separated from the inlet 15 of the one-way valve, the inlet 15 and the outlet 16 of the one-way valve are connected, and the fluid flows through the inlet 15 and the outlet 16 of the one-way valve in turn; with the pressure of the inlet 15 and the outlet 16 of the one-way valve As the difference decreases, the spring 14 drives the valve core block 13 to return, and the valve core block 13 presses against the inner edge of the inlet 15 of the one-way valve again, thereby blocking the passage of fluid again.
