[0030] (1) By setting up an anti-backflow component in the present invention, specifically when the connecting pipe head is connected to the drain pipe, at this time, the two pistons are subjected to force and will squeeze the second spring. At the same time, due to the limiting effect of the fixed plate, the second spring will contract and store energy.

When the connecting pipe head continues to advance, several limiting balls will pass through the limiting ring and be on the left side of the limiting ring. At this time, the limiting sleeve is released, and at the same time, the first spring will generate a certain resilience and drive the limiting sleeve to reset. When the limiting sleeve resets, it will squeeze several limiting balls. At this time, the outer surfaces of several limiting balls will contact the outer surface of the drain pipe. At this time, several limiting balls limit the connecting pipe head through the limiting ring. Through this simple and convenient connection method, the installation time is greatly reduced, and the work efficiency is greatly improved.

[0032] (3) By setting up an adjustment component in the present invention, specifically, the knob is rotated clockwise to drive the threaded rod to rotate. When the threaded rod rotates, it will drive the moving frame to move. When the moving frame moves, it will drive the adjusting roller on the front to move towards the back. At this time, through the action of the two adjusting rollers, the first drainage pipe will be clamped to adjust the flow rate of the gas or liquid inside the first drainage pipe. By adjusting the negative pressure intensity, it is applicable to different patients, avoiding gastric mucosa damage caused by excessive suction force and the occurrence of stomachache and other situations, greatly improving the versatility of the equipment.

When the connecting pipe head 321 is connected to the drain pipe 323, at this time, the two pistons 335 are subjected to force and will squeeze the second spring 334. At the same time, the second spring 334 will contract and store energy under the limiting action of the fixed plate 331. At this time, the two pistons 335 are respectively separated from the drain pipe 323 and the connecting pipe head 321, and at this time, the liquid can flow. When the connecting pipe head 321 is separated from the drain pipe 323, the two pistons 335 will be reset under the action of the resilience of the second spring 334.

Subsequently, drainage is carried out through the negative pressure drainage device body 111. At this time, the staff can adjust the flow rate. Specifically, rotate the knob 125 clockwise to drive the threaded rod 126 to rotate. When the threaded rod 126 rotates, it will drive the moving frame 124 to move. Then, when the moving frame 124 moves, it will slide inside the chute 127 through the pin shaft. At the same time, 217 provides a certain limit for the movement track of the moving frame 124.

When the connecting pipe head 321 continues to be pushed forward, several limit balls 326 will pass through the limit ring 324 and be on the left side of the limit ring 324. At this time, the limit sleeve 322 is released, and at the same time, the first spring 325 will generate a certain resilience and drive the limit sleeve 322 to reset. When the limit sleeve 322 resets, it will squeeze several limit balls 326, and several limit balls 326 will approach each other under the extrusion of the limit sleeve 322. At the same time, the outer surfaces of several limit balls 326 will come into contact with the outer surface of the drain pipe 323. At this time, several limit balls 326 will limit the connecting pipe head 321 through the limit ring 324. At this time, the connection and fixation of the connecting pipe head 321 and the drain pipe 323 are completed. For disassembly, just toggle the limit sleeve 322 to the right, and at this time, the connecting pipe head 321 can be detached from the outside of the drain pipe 323. Through this simple and convenient connection method, the installation time is greatly reduced, and the work efficiency is greatly improved;

[0072] When the connecting pipe head 321 is connected to the drain pipe 323, the two pistons 335 will come into contact. At this time, the two pistons 335 will move away from each other under the action of force. At the same time, when the pistons 335 move, they will drive the support rods 333 to move together. When the support rods 333 move, they will slide inside the fixed plate 331. At the same time, a number of holes 332 are provided inside the fixed plate 331. The number of limit sleeves 322 facilitates the flow of the liquid inside the negative pressure drainage device body 111. When the support rods 333 move, the pistons 335 will squeeze the second spring 334. At the same time, the second spring 334 will contract and store energy under the limiting action of the fixed plate 331. At this time, the two pistons 335 are respectively separated from the drain pipe 323 and the connecting pipe head 321, and at this time the liquid can flow. When the connecting pipe head 321 is separated from the drain pipe 323, the two pistons 335 will return to their original positions under the action of the resilience of the second spring 334. At the same time, the two first springs 325 will respectively seal the inside of the connecting pipe head 321 and the drain pipe 323 to avoid the outflow of the liquid, reduce the outflow of the liquid in the pipe to the outside when treating the liquid inside the collection bottle 312, reduce the pollution of the environment, and at the same time avoid the infection of patients or medical staff, greatly improving the practicability of the device.
