[0002] Wound irrigation is a method used to clean wounds, aiming to remove dirt, bacteria and necrotic tissue from the wound surface to reduce the risk of infection and promote healing.

[0003] Wound cleaning generally includes water flushing, sodium chloride flushing solution, hydrogen peroxide solution flushing, iodine tincture flushing, soapy water flushing, etc., which can speed up wound healing and prevent slow recovery.

[0004] Water flushing: If there is blood stains or other secretions on the wound, you can simply clean the wound by flushing it with water, which is helpful to remove the secretions and prevent infection in the wound.

[0005] Sodium chloride rinse: Using sodium chloride rinse to clean the wound tissue can have a bactericidal and anti-inflammatory effect, promote wound tissue healing, and prevent slow recovery.

[0006] Rinse with hydrogen peroxide solution: It has antibacterial and anti-inflammatory effects. Hydrogen peroxide solution can be used to rinse the wound tissue, which is beneficial for removing local secretions or blood scabs, preventing slow wound healing, and accelerating the improvement of skin tissue.

[0007] Iodine flushing: In case of skin trauma, you need to go to a regular hospital to flush the wound tissue with iodine, which is beneficial to clean the local dirt or foreign matter on the wound, promote the growth of new tissue, prevent inflammation, have a good debridement effect, and improve local congestion and swelling symptoms.

[0008] Rinse with soapy water: After the skin is scratched or bitten, the wound tissue needs to be cleaned with soapy water in time, which helps prevent bacteria or harmful substances from entering the blood, reduces the chance of illness, and achieves the effect of debridement.

[0009] During the wound cleaning process, doctors usually spray liquid onto the wound surface through a syringe.

[0047] Specifically, the positioning through hole 41 is a rectangular through hole. By replacing positioning pads 4 of different sizes, the length of the positioning through hole 41 is at least one centimeter greater than the longest length of the wound surface, and the width of the positioning through hole 41 is at least one centimeter greater than the longest width of the wound surface.

[0048] Specifically, an infrared rangefinder 13 is also provided on the side of the top frame 11 facing the positioning pad 4, and the controller is electrically connected to the infrared rangefinder 13; the infrared rangefinder 13 is used to detect the distance data between the infrared rangefinder 13 and the wound surface and send it to the controller; the controller is used to determine the height data of the wound surface according to the distance data, and then control the first driver 5 and the second driver 6 respectively according to the height data, so that the flushing mechanism 2 and the liquid suction mechanism 3 respectively operate in the positioning through hole 41, and cooperate with the positioning pad 4 abutting against the patient's skin to perform a flushing operation.

[0049] Specifically, the detection point of infrared ranging is located in the positioning through hole 41 .

The two fixed rods 53 are detachably connected to the positioning pad 4, and by pressing down at multiple points, the positioning pad 4 is ensured to better contact the patient's skin.

[0051] Specifically, one end of the two fixing rods 53 away from the mounting plate 52 of the first electric control slide 51 is detachably connected to the positioning pad 4 through a spring seat 54. The arrangement of the two spring seats 54 can ensure the tightness of the positioning pad 4 and the patient, and can also avoid excessive pressure on the patient.

[0052] Specifically, the positioning through hole 41 is located between the two fixing rods 53 .

[0053] The flushing mechanism 2 includes a nozzle 21, a first connecting pipe 22, a first pump body 23 and a first telescopic hose (not shown in the figure), the second driver 6 drives and connects the first connecting pipe 22, one end of the first connecting pipe 22 is provided with the nozzle 21, the other end of the first connecting pipe 22 is connected to one end of the first telescopic hose, and the other end of the first telescopic hose is used to connect to the external liquid storage mechanism; the first pump body 23 is provided on the first connecting pipe 22, and one end of the first connecting pipe 22 provided with the nozzle 21 is inclined toward the positioning pad 4; the controller is electrically connected to the first pump body 23, and the controller is used to control the second driver 6 to drive the nozzle 21 to align with the wound surface located in the positioning through hole 41, so that the first pump body 23 drives the liquid in the external liquid storage mechanism to pass through the first telescopic hose and the first connecting pipe 22 in turn, and spray the liquid to the wound surface through the nozzle 21. The horizontal height of the nozzle 21 when spraying the liquid will be the height of the liquid suction mechanism 3, which can avoid the collision between the flushing mechanism 2 and the liquid suction mechanism 3 during the process of sucking the waste liquid.

The second connecting tube 32 extends into the positioning through hole 41 through the flexible suction head 31, which can avoid rigid contact with the patient's wound surface.

[0056] The second driver 6 includes a second electrically controlled slide 61, a first adjustment mechanism 7 and a second adjustment mechanism 8. The second electrically controlled slide 61 is slidably connected to the track 15. The first adjustment mechanism 7 and the second adjustment mechanism 8 are both arranged on the side of the second electrically controlled slide 61 away from the track 15. The second electrically controlled slide 61 is used to vertically adjust the horizontal heights of the first adjustment mechanism 7 and the second adjustment mechanism 8 along the track 15. The second adjustment mechanism 8 is located on the side of the first adjustment mechanism 7 away from the positioning pad 4. The first adjustment mechanism 7 is driven to be connected to the liquid suction mechanism 3. The first adjustment mechanism 7 is used to drive the first adjustment mechanism 7 to move to a preset height when the second electrically controlled slide 61 drives the first adjustment mechanism 7 to move to the preset height. The liquid suction mechanism 3 moves horizontally so that the liquid suction mechanism 3 absorbs the waste liquid in the positioning through hole 41; the second mechanism drives the connection flushing mechanism 2, and the second adjustment mechanism 8 is used to drive the flushing mechanism 2 to move horizontally when the second electric control slide 61 drives the first adjustment mechanism 7 to move to a preset height, so that the flushing mechanism 2 sprays liquid into the positioning through hole 41; the controller is electrically connected to the second electric control slide 61, the first adjustment mechanism 7 and the second adjustment mechanism 8 respectively, and the controller is used to control the second electric control slide 61, the first adjustment mechanism 7 and the second adjustment mechanism 8 respectively, so that the flushing mechanism 2 and the liquid suction mechanism 3 respectively operate in the positioning through hole 41.

[0057] The first adjustment mechanism 7 includes a first linear motor 71, a first mounting frame 72, a retractor 73 and a fixed frame 74.

The spraying of liquid does not require the nozzle 21 to be fully aligned, so the flushing mechanism 2 only needs to move laterally to meet the needs of flushing the wound surface. The setting of the connecting frame 83 can increase the linear distance between the flushing mechanism 2 and the frame 1, thereby increasing the adjustment distance of the liquid suction mechanism 3 in disguised form.

[0060] The second linear motor 81 is located at a side of the first linear motor 71 away from the positioning pad 4 ; the first linear motor 71 and the second linear motor 81 are arranged in parallel and spaced apart.
