The negative pressure drainage tube is made of medical polymer materials. After the injection of local anesthetics, it is as soft as a sponge, which plays a compressive and supporting role around the anus, and performs infiltration and long-term sustained-release analgesia around the anus. When there is intestinal bleeding, patients can find it early, report it early, and deal with it early to avoid medical accidents.

[0025] 2. The drainage hemostasis and sustained-release analgesia device for anorectal department can achieve the purpose of quantitative injection and reduced shaking. The liquid storage tank can be used to store anesthetics. After pressing the second pressing plate alone, the rubber airbag deflates, thereby unlocking the float plate, and the float plate will automatically float up and float on the liquid surface. Then, the second pressing plate can be pressed and the first pressing plate can be pressed. The movable column and the second piston move down, which is convenient for pressing the anesthetic in the pre-stored cylinder into the infusion pipeline. The anesthetic is injected into the negative pressure drainage pipe through the injection pipeline. The entire injection operation is convenient and fast, and the capacity of the pre-stored cylinder is fixed. The pump pressure is the same each time, which is convenient for better control of the injection volume. After releasing the second pressing plate, the rubber airbag expands and presses against the float plate. In the process of moving the device, the float plate can reduce the shaking of the anesthetic in the liquid storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

After anesthetics such as ropivacaine are injected into the honeycomb material wall of the negative pressure drainage tube 1, the negative pressure drainage tube 1 rapidly expands to form a soft body, and a dumbbell-shaped structure is formed at the tooth line. The arc-shaped top support frame 3 better matches the dumbbell-shaped structure, which can prevent the device from loosening from the human body.

[0039] In this embodiment, Figure 1 , Figure 2 and Figure 8 As shown, a top plug 8 is threadedly connected to the top of the liquid storage tank 7, and a liquid inlet hole 9 is opened on the top plug 8. Elastic sealing sheets 10 are fixed on the inner wall of the liquid infusion pipe 4 and the inner wall of the liquid inlet hole 9, and the elastic sealing sheets 10 are evenly distributed circumferentially in the liquid infusion pipe 4 and the liquid inlet hole 9. The liquid inlet hole 9 can be used to pass liquid into the liquid storage tank 7, and the liquid infusion pipe 4 can be used for infusion. The circumferentially evenly distributed elastic sealing sheets 10 can play a role in preventing backflow.

[0040] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the liquid pressure mechanism 11 includes a movable column 1101, and the movable column 1101 passes through the liquid storage tank 7. The top of the liquid storage tank 7 is connected to the first pressing plate 1102 through the first compression spring 1103, and the first compression spring 1103 is wrapped around the outside of the movable column 1101. When the first pressing plate 1102 is pressed, the movable column 1101 moves down with the first pressing plate 1102. After the first pressing plate 1102 is released, the first pressing plate 1102 can automatically pop up under the action of the first compression spring 1103.

When the rubber airbag 1110 is in an expanded state, it will press against the floating plate 12, and the movable column 1101 is locked together with the floating plate 12. When the first pressing plate 1102 is held by hand to press the second pressing plate 1107, the first piston 1106 and the movable pipe 1108 move downward together with the second pressing plate 1107. At this time, the movable pipe 1108 draws air upward, and the rubber airbag 1110 deflates, which facilitates unlocking the floating plate 12 and the movable column 1101.

[0043] In this embodiment, Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, four rubber airbags 1110 are provided, and the four rubber airbags 1110 are evenly distributed in the inflation channel 1109 in the circumferential direction.

The anesthetic is pressed into the infusion pipe 4, and the anesthetic is finally injected into the negative pressure drainage pipe 1 through the injection pipe 5. The honeycomb material wall of the negative pressure drainage pipe 1 expands rapidly to form a soft body, forming a dumbbell-shaped structure at the tooth line, and then slowly released through the anal canal mucosal tissue, which can play a role in long-term sustained-release analgesia. The exhaust drainage pipe 2 reserved in the middle has the function of exhaust drainage and observation of internal bleeding. After releasing the first pressing plate 1102 and the second pressing plate 1107, the first pressing plate 1102, the movable column 1101 and the first piston 1106 bounce up as a whole, and the rubber airbag 1110 expands and presses against the floating plate 12.
