This type of trauma is relatively common in clinical practice. Improper treatment can easily lead to infection, delayed wound healing or complications. In severe cases, it may have a long-term impact on the patient's quality of life. In the process of trauma treatment, wound irrigation is a key step. Its purpose is to remove dirt, bacteria and necrotic tissue in the wound through flushing and cleaning, thereby reducing the risk of infection and promoting wound healing, minimizing the disability rate and improving the degree of functional recovery.

[0011] Preferably, the cylindrical tube is provided with a movable mechanism for adjusting the flushing position of the irrigation nozzle, the movable mechanism includes a cylindrical block fixedly connected to one end of the cylindrical tube close to the incomplete gear, a support rod fixedly connected to the side of the fixed rod close to the cylindrical block, an inclined groove is provided on the outer contour of the cylindrical block for the support rod to drive the cylindrical tube to perform axial reciprocating movement, and the end of the support rod passes through the inner wall of the inclined groove and is movably connected.

[0012] Preferably, the cylindrical shell is provided with a drainage mechanism for the irrigation nozzle to flush the wound, and the drainage mechanism includes liquid inlet pipes that are penetrated and fixedly connected at symmetrical positions near both ends of the top side of the cylindrical shell, and the two ends of the liquid inlet pipes are penetrated and fixedly connected with a liquid storage box for storing cleaning liquid, and the inner wall of the cylindrical shell is axially movably connected to a piston plate for extracting and discharging the cleaning liquid inside the liquid storage box, and the piston plate is penetrated and fixedly connected by the cylindrical tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a combination of an adjustment mechanism, an arc-shaped slider and a track plate on the fixed rod, the automatic adjustment function of the irrigation nozzle is realized. The adjustment mechanism and the arc-shaped slider cooperate with each other to enable the irrigation nozzle to move freely in the arc-shaped track and adjust the spray angle according to the specific location of the patient's wound, so as to facilitate the cleaning of dirt in the crevices of the patient's wound, thereby achieving a more comprehensive and accurate flushing effect. Compared with traditional devices, this design not only reduces the frequency of manual adjustment by medical staff, but also greatly improves the efficiency and cleanliness of wound cleaning, effectively reducing the risk of infection.

[0016] Second, the moving mechanism of the inclined groove and the support rod designed on the columnar block enables the irrigation nozzle to achieve reciprocating movement. At the same time, the horizontal movement of the semicircular frame in the guide groove further expands the cleaning range of the nozzle, ensuring that the irrigation nozzle can flexibly cover every corner of the wound area. It is particularly suitable for difficult-to-reach wound gaps, effectively improving the comprehensive flushing effect of the wound area. Compared with the traditional fixed nozzle design, this device significantly improves the comprehensiveness and flexibility of cleaning.

[0017] 3. A piston plate, a one-way liquid inlet valve and a one-way liquid discharge valve are arranged inside the cylindrical tube. The reciprocating movement of the piston plate realizes the continuous extraction and quantitative discharge of the cleaning liquid. The axial reciprocating movement of the piston plate in the cylindrical shell ensures the continuous supply of the cleaning liquid during the cleaning process. At the same time, the quantitative control of the one-way valve avoids the unstable injection caused by uneven pressure, which not only ensures the cleaning continuity of the irrigation nozzle, but also improves the removal effect of dirt in the wound gap, which helps to accelerate the healing process of the wound.

[0018] Fourth, a swingably connected fan plate is provided on the L-shaped rod, so that during the cleaning process, the fan plate can fan the wound area. Driven by the swing rod, the fan plate coordinates with the horizontal movement of the semicircular frame to evenly fan and cool the wound area. The fanning operation can not only reduce the pain of the patient during the flushing process, but also accelerate the drying and healing of the wound area, improve the patient's comfort and treatment effect. This function achieves multiple care effects while cleaning, further enhancing the practicality of the device.

[0019] The coordinated use of the above-mentioned structure solves the problem that in actual use of the existing device, medical staff need to manually adjust the position of the irrigation nozzle to fully rinse the wound, which is time-consuming and labor-intensive, occupies medical resources, and therefore it is difficult to automatically adjust the irrigation nozzle to fully rinse the patient's wound area.
