Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 4, including the left and right axial gas cylinder 1, the right side of the lower end of the gas cylinder 1 is provided with a left-right direction and a rectangular hole 2 passing through the inside and outside, the gas cylinder 1 is coaxially slidably connected with a piston 3, and the right end of the piston 3 is coaxially connected. A cylindrical rod 4 is provided, and the right end of the cylindrical rod 4 is provided with a connecting block 5 in the up and down direction. The lower end of the connecting block 5 penetrates the rectangular hole 2 and is provided with a handle 6 in the up and down direction. The left end of the cylinder 7 is provided with a collection cylinder 8 coaxially, the left end of the collection cylinder 8 is provided with a suction pipe 9, and the free end of the suction pipe 9 is provided with an upper and lower axial suction head 10, and the outer diameter of the suction head 10 is larger than that of the suction pipe 9. Outer diameter, the left end of the air cylinder 1 is provided with an air outlet pipe 11 located above the cylinder 7 and in the left and right axial directions.

In order to facilitate the use of the device, the lower end of the gas cylinder 1 is provided with a fixing rod 13 located on the right side of the rectangular hole 2 and in the up-down direction.

In order to enable the piston 3 to reset, the right end of the handle 6 is connected to the fixed rod 13 via the spring 14 .

In order to prevent the gas in the gas cylinder 1 from entering the collecting cylinder 8 , the cylinder 7 is provided with a one-way inlet valve 15 with an opening facing to the right.

In order to prevent the patient's breathing during the smooth process, a plurality of arc-shaped grooves 16 are formed on the outer edge of the suction head 10 , which are evenly distributed along the circumferential direction thereof and penetrate up and down.

In order to increase the comfort of the patient, the outer edge of the suction tube 9 is coaxially slidably connected with a T-shaped bite block 17 with a large upper and a lower small.

When the utility model is in use, first place the suction head 10 on the patient's airway opening, and then slide the bite block 17 down along the outer edge of the suction tube 9. When the bite block 17 slides to the patient's mouth, the patient's upper and lower The lips are in contact with the lower end of the bite block 17, and the bite block 17 is fixed on the patient's mouth, so that the suction tube 9 slowly enters the patient's mouth, and the suction tube 9 drives the suction head 10 into the patient's airway slowly, and the suction head 10 enters the patient's airway process. , the patient can breathe through a plurality of arc-shaped grooves 16 on the suction head 10;

When the suction head 10 is in contact with the sputum or blood clot in the patient's airway, stop the suction tube 9 from sliding, hold the fixing rod 13 with one hand, hook the handle 6 with two fingers and apply force to the right, the handle 6 is compressed to the right The spring 14 drives the connecting block 5 to slide to the right in the rectangular hole 2, the connecting block 5 drives the cylindrical rod 4 to move to the right, the cylindrical rod 4 drives the piston 3 to slide to the right in the gas cylinder 1, and a negative pressure is formed in the cavity on the left side of the piston 3, The one-way air outlet valve 12 in the air outlet pipe 11 is closed, the one-way air inlet valve 15 in the cylinder 7 is opened, and the sputum or blood clot in the patient's airway is sucked into the suction head 10, and then enters the collection tube 8 through the suction tube 9 ;

If the sputum or blood clot does not fully enter the suction head 10, loosen the handle 6, the spring 14 drives the handle 6 to move to the left, the handle 6 drives the cylindrical rod 4 to move to the left through the connecting block 5, and the cylindrical rod 4 drives the piston 3 to slide to the left, At this time, the air pressure in the cavity at the left end of the piston 3 increases, the one-way air inlet valve 15 in the cylinder 7 is closed, the one-way air outlet valve 12 in the air outlet pipe 11 is opened, and the air cylinder 1 at the left end of the piston 3 reaches the air cylinder 1 through the air outlet pipe 11.
