Because they are fully disclosed, they will not be repeated in this article.

[0041] Through the above structure, the working principle of the negative pressure drainage device for post-implantation wound provided by the present application is as follows:

[0042] Fill the liquid storage tank 18 with an appropriate amount of disinfectant, and then place the device stably in a suitable position next to the patient's head;

[0043] Next, push the cushion 221 to slide on the drainage hose 14 and the disinfectant delivery hose 20, so that the cushion 221 is at a suitable distance from the drainage head 15 and the ball-shaped nozzle 21, and then let the patient open his mouth, put the cushion 221 into the patient's mouth, and let the patient's upper teeth and lower teeth bite into the tooth grooves 223 on the silicone pad 222 respectively, and adjust the drainage head 15 and the ball-shaped nozzle 21 to align with the wound site of the patient after the dental implant surgery, so as to avoid the patient's mouth being kept open for a long time and feeling fatigue during the subsequent drainage process, so as to avoid the teeth directly biting the drainage hose 14 and the disinfectant delivery hose 20;

[0044] Then, open the check valve 1 7, the check valve 2 10 and the check valve 4 27, and keep the check valve 3 12 in the closed state, start the negative pressure vacuum pump 4, and its suction end draws air from the suction cylinder 5 through the suction pipe 6. The suction cylinder 5 is connected with the negative pressure tank 2, so that a negative pressure environment is formed in the negative pressure tank 2. The top of the left side of the negative pressure tank 2 is connected with the drainage hose 14 through the connecting pipe 13. The drainage head 15 at the left end of the drainage hose 14 is placed at the wound after the dental implant surgery. Then, under the action of negative pressure, the exudate from the wound after the dental implant surgery is sucked into the drainage hose 14, and then flows into the negative pressure tank 2 for temporary storage and collection, so as to achieve the effect of negative pressure drainage of the wound and promote wound healing.

[0045] In the process of the negative pressure vacuum pump 4 pumping air to form negative pressure drainage in the negative pressure tank 2, the gas pumped by the negative pressure vacuum pump 4 enters the fixed cylinder 3 through the outlet pipe 8, and the power generated when the gas flows from the outlet pipe 8 to the fixed cylinder 3 is converted into mechanical energy, so that the gas flow entering the fixed cylinder 3 drives the blades 167 to rotate, and then drives the vertical shaft 166 and the active bevel gear 168 at the bottom thereof to rotate, and the active bevel gear 168 and the driven bevel gear 169 engage to drive the horizontal shaft 163 to rotate, and the external threaded joint 164 and the stainless steel filament 165 of the left end screw of the horizontal shaft 163 rotate accordingly, so that the stainless steel filament 165 can rotate in the drainage hose 14 and the drainage head 15. During the drainage process, the drainage channels in the drainage hose 14, the drainage head 15 and the connecting pipe 13 can be effectively prevented from being blocked, thereby ensuring the smoothness of the drainage and avoiding the influence of the wound healing due to the blockage;

[0046] When the negative pressure vacuum pump 4 is evacuating air to form a negative pressure in the negative pressure tank 2, the gas entering the fixed cylinder 3 enters the liquid storage tank 18 through the exhaust pipe 19, so that the air pressure in the liquid storage tank 18 is gradually increased, and then the air pressure can be used to spray the disinfectant contained in the liquid storage tank 18 through the connecting pipe 2 19 and the disinfectant delivery hose 20, and finally from the ball-shaped nozzle 21 to the wound site after the dental implant operation, so as to achieve flushing, cleaning and disinfection and sterilization of the wound site, reduce the risk of wound infection, and promote wound healing. In addition, by providing the ball-shaped nozzle 21, the range of disinfectant spraying can be increased, and the wound site can be fully disinfected. The dirty liquid generated by flushing is sucked into the drainage head 15, and then flows into the negative pressure tank 2 through the drainage hose 14 and the connecting pipe 13 in turn. After the drainage and flushing of the wound site are completed, the negative pressure vacuum pump 4 is stopped, and the check valve 1 7, the check valve 2 10 and the check valve 4 27 are closed;

[0047] When the device is used to perform negative pressure drainage on the wound of a patient after dental implant surgery and no cleaning and disinfection is required, open the check valve 1 7 and the check valve 3 12, keep the check valve 2 10 and the check valve 4 27 in a closed state, start the negative pressure vacuum pump 4, and according to the above-mentioned operating principle, negative pressure drainage can be performed on the wound and blockage can be prevented during the drainage process, so that the gas entering the fixed cylinder 3 is finally discharged directly into the atmosphere from the exhaust pipe 2 11.
