In addition, as the foreign body collection box is filled with sputum, the movement of the push plate piston is gradually affected.

[0007] The utility model provides the following technical solutions:

[0008] An airway patency device, comprising:

[0009] A sputum storage tank, wherein a tank cover is threadedly connected to the tank opening at the top of the sputum storage tank, a sputum suction tube and an air extraction tube are respectively plugged into two joints at the top of the tank cover, the other end of the air extraction tube is connected to a cylindrical tube, a piston plate is slidably connected inside the cylindrical tube, a one-way exhaust valve is connected to one side of the cylindrical tube, and the one-way exhaust valve is located above the air extraction tube;

[0010] The reciprocating assembly is arranged in the cylindrical cylinder and is used to drive the piston plate to reciprocate so as to generate negative pressure in the sputum storage tank, without the need for manual operation by medical staff, thereby reducing the workload of medical staff;

[0011] The anti-detachment component is arranged on the sputum suction tube and the air extraction tube to prevent the sputum suction tube and the air extraction tube from being separated from the tank cover joint during operation, which helps to ensure the air tightness of the device.

[0012] In one possible design, the reciprocating assembly includes a reciprocating screw arranged in a cylindrical barrel, one end of the reciprocating screw is rotatably mounted on the inner wall of the cylindrical barrel, a rotating plate is fixedly arranged in the cylindrical barrel, the other end of the reciprocating screw is rotatably mounted on one side of the rotating plate, a matching sliding seat is threadedly connected to the reciprocating screw, the sliding seat and the piston plate are fixedly connected by two connecting rods, and a micro motor for driving the reciprocating screw to rotate is fixedly mounted on the outer wall of the cylindrical barrel.

[0013] In a possible design, the top and bottom of the sliding seat are fixedly provided with limit blocks to prevent the sliding seat from rotating when the reciprocating screw rotates, and the inner wall of the cylindrical tube is provided with a limit groove for slidingly connecting the corresponding limit blocks.

[0014] In a possible design, a power storage block for supplying power to the micro motor is fixedly disposed at the bottom of the outer wall of the cylindrical tube, and a charging interface is disposed on the power storage block.

[0015] In a possible design, the anti-detachment component includes a fastener provided on the outer wall of the sputum suction tube and the air extraction tube, and the two joints on the top of the tank cover and the sputum suction tube and the air extraction tube are reinforced by tightening the corresponding fasteners.

[0016] In a possible design, the end of the sputum suction tube is provided with a plurality of side suction holes for improving sputum suction efficiency.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0018] In this application, the specific usage process is as follows:

[0019] Preparation: The medical staff first ensures that the sputum storage tank is empty, and then fixes it tightly with the tank cover through threaded connection. Then, the suction tube and the air extraction tube are respectively inserted into the corresponding joints on the top of the tank cover, and reinforced by tightening to ensure that the connection is tight and there is no air leakage. Then, the power of the micro motor is turned on to prepare for the upcoming suction operation.

[0020] Suction operation: insert the end of the suction tube into the patient's airway to the position where suction is required, start the micromotor, and the micromotor drives the reciprocating screw to rotate. The rotation of the reciprocating screw causes the sliding seat to move back and forth in the cylindrical tube, and the piston plate is driven to reciprocate in the cylindrical tube through the connecting rod. When the piston plate moves away from the suction pipe, negative pressure is generated in the sputum storage tank, and the sputum or blood clots in the patient's airway are extracted through the suction tube. The sputum or blood clots are sucked into the sputum storage tank. The one-way exhaust valve ensures that the gas can only be discharged in one direction during the reciprocating motion of the piston plate, forming a continuous negative pressure. When the piston plate moves toward the direction close to the suction pipe, the gas is discharged through the one-way exhaust valve and prepares for the next suction operation.

[0021] The utility model has the following beneficial effects:

[0022] Automated operation: Through the design of the reciprocating component, the suction operation is automated, eliminating the need for manual operation by medical staff, reducing the workload of medical staff and improving work efficiency.

[0023] Ensure air tightness: The tight design ensures that the suction tube and the air extraction tube are tightly connected to the tank cover without air leakage, ensuring the air tightness of the device and improving the suction effect.

[0024] Improve suction efficiency: The multiple side suction holes at the end of the suction tube increase the suction surface area, improve the suction efficiency, and can more comprehensively absorb the sputum or blood clots in the patient's airway.

[0025] The utility model automatically drives the piston plate to reciprocate in the cylindrical tube through the reciprocating component to generate negative pressure, thereby realizing automatic sputum suction. There is no need for manual operation by medical staff, thus reducing the workload of medical staff. At the same time, the provision of the anti-detachment component ensures the airtightness of the device and improves the sputum suction effect. In addition, the side suction hole design at the end of the sputum suction tube further improves the sputum suction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
