Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a wound cleaning and nursing device for orthopedic trauma. Background Art

[0002] The orthopedic wound cleaning process is a meticulous and important step to ensure wound cleanliness, reduce the risk of infection, and promote healing. The general operation process is as follows: First, remove the old gauze and dressing from the affected area of the patient, then rinse and clean the wound with a disinfectant cleaning solution. After cleaning, wipe off the moisture with a clean gauze or medical cotton to keep the wound dry. Finally, re-dress the affected area and wrap a new gauze.

[0003] In the above operation process, generally, doctors perform manual operations. The doctor needs to hold the cleaning bottle and aim it at the patient's wound, and then pour the cleaning bottle to let the cleaning solution flow out of the bottle mouth, and use the flowing cleaning solution to rinse the wound. Generally, during the cleaning process, the doctor needs to manually clean the stains and dressings near the wound. Since a doctor cannot pour the cleaning solution and clean the stains near the wound at the same time, the cleaning work generally requires multiple people to cooperate. Moreover, during the cooperation of multiple people, it is difficult to timely adjust the flow rate and direction of the cleaning solution according to the cleaning position, resulting in some cleaning solution being lost and wasted during the cleaning process. Therefore, based on the above problems, the present invention provides a wound cleaning and nursing device for orthopedic trauma to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wound cleaning and nursing device for orthopedic trauma. By setting a positioning component and a cleaning mechanism, the operator can perform the cleaning treatment on the patient's wound alone, saving manpower while improving the efficiency of wound cleaning. Moreover, during the cleaning process, the cleaning solution can be reasonably utilized to avoid waste. When the wound cleaning is completed, the positioning component and the cleaning mechanism can remove and dry the remaining liquid at the patient's wound, improving the efficiency of the wound cleaning process and avoiding discomfort to the patient caused by too long cleaning time. Through the above settings, the problems of low cleaning efficiency and easy loss and waste of the cleaning solution during the current cleaning of the patient's wound can be solved.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] Optionally, a placement plate is fixedly connected to the bottom of the first positioning plate. The width of the placement plate is greater than the width of the first positioning plate. First elastic bending parts are symmetrically installed at the middle position of the first positioning plate. The first elastic bending parts have an outwardly convex arc-shaped contour. The middle position of the top of the first positioning plate is set as an open structure.

[0009] Optionally, a second elastic bending part is fixedly connected to the connection position between the guide plate and the first positioning plate. The second elastic bending part has an outwardly convex arc-shaped contour. Guide holes are respectively opened at the middle position and the end far from the second elastic bending part of the guide plate. A hook plate is fixedly connected to the end of the guide plate far from the first positioning plate. The hook plate is perpendicular to the guide plate.

[0010] Optionally, a return spring is fixedly connected to the outer wall of the grip. The return spring is of a conical structure. One end of the return spring far from the grip is fixedly connected to a base. A limiting rod is fixedly connected to the outer wall of the base. A pulley is sleeved at one end of the limiting rod.

[0011] Optionally, a conical expansion plate is fixedly connected to the bottom of the grip. The conical expansion plate has a conical contour and the bottom is of a segmented structure. An extrusion sleeve is slidably connected to the outer wall of the conical expansion plate. The bottom of the extrusion sleeve is of a segmented structure.

[0012] Optionally, a drainage plate is fixedly connected to the bottom of the second positioning plate. The drainage plate has a downwardly bent arc-shaped contour. A plug-in part is fixedly connected to the bottom of the hanging rod. A jack with a size matching that of the plug-in part is opened at the top of the second positioning plate.

[0013] Optionally, the cleaning mechanism includes a storage tray fixedly connected to the top of the mounting plate. The storage tray and the mounting plate are fixed by screws. Two storage tanks are fixedly connected to the top of the storage tray. A piston is slidably connected in the storage tank. A pressing rod is fixedly connected to the middle position at the top of the piston. A hanging ring is fixedly connected to the end of the pressing rod.

[0014] Optionally, a first infusion tube is fixedly connected to the bottom of one of the storage tanks. A first valve is installed on the first infusion tube. A second infusion tube is fixedly connected to the bottom of the other storage tank. A second valve is installed on the second infusion tube. The output ends of the first infusion tube and the second infusion tube converge onto the same pipe.

[0015] Optionally, a foot pedal is fixedly connected to the bottom of the bracket. A chain is fixedly connected to the top of the foot pedal. A connecting rod is hung on the top of the chain. The top of the connecting rod is of a hook-type structure. A limiting groove corresponding to the position of the connecting rod is formed on the mounting plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting the positioning component and the cleaning mechanism, compared with the existing cleaning methods, the cleaning and nursing equipment provided in this application enables the operator to clean the patient's wound by single-person operation, saving manpower while improving the efficiency of wound cleaning. Moreover, during the cleaning process, the cleaning liquid can be reasonably utilized to avoid waste. After the wound cleaning is completed, the positioning component and the cleaning mechanism can remove and dry the liquid remaining at the patient's wound, improving the efficiency of the wound cleaning process and avoiding discomfort to the patient caused by too long cleaning time.

[0018] By setting the first positioning plate and the second positioning plate, not only can the fixation effect of the patient's calf be achieved, but also during the process of the operator placing the patient's calf between the first positioning plate and the second positioning plate, the placement efficiency is high, the safety of the patient's calf is good, and the comfort of the patient's calf is high after placement, improving the comfort of the patient during the entire cleaning process. In addition, after the patient's calf is placed on the first positioning plate and the second positioning plate, the patient's calf is in a state of tilting towards the second positioning plate. During the cleaning process, the cleaning liquid flowing from the patient's calf will flow along the tilted calf of the patient to the position of the second positioning plate, and then under the drainage effect of the downwardly bent arc-shaped contour of the drainage plate, the cleaning liquid will fall into the liquid accumulation tank. Such a setting not only makes the cleaning liquid not stay on the patient's calf during the cleaning process, but also does not cause the cleaning liquid to flow to other parts of the patient except the calf during the cleaning process, improving the comfort of the patient and the recovery effect of the cleaning liquid.

[0019] By setting the grip, the user can first determine the specific location of the patient's wound and then selectively slide the grip onto the corresponding guide plate, ensuring that the cleaning liquid flowing out of the liquid outlet tube can accurately wash the wound location of the patient, avoiding waste of the cleaning liquid. The grip can not only slide on the guide plate but also change the angle at the bottom of the grip by rotating the grip, thereby adjusting the angle of the liquid outlet tube by means of the adjustment of the grip angle to clean wounds at different positions. In all the above operations, the operator can fully achieve them with one hand, saving the input of human resources and improving the efficiency of wound cleaning. The user can slide down the extrusion sleeve and, by means of the extrusion of the extrusion sleeve, contract the conical contour of the conical expansion plate expanding outward, thereby achieving the effect of changing the size of the end of the liquid outlet tube. By changing the size of the end of the liquid outlet tube, the speed and range of the liquid flowing out of the liquid outlet tube can be changed, making it more convenient for the operator to perform local flushing and large-range cleaning of the patient's wound, improving the convenience and efficiency of wound cleaning.

[0020] By setting the foot pedal and the storage tank, not only can the cleaning liquid be supplied to the liquid outlet tube, but also air can be supplied to the infusion tube after cleaning the patient's wound. By means of the air, the wound of the patient is blown, blowing away the cleaning liquid attached to the patient's calf and accelerating the drying efficiency of the cleaning liquid. Moreover, the user can adjust the force of stepping on the foot pedal according to the need, thereby changing the speed of the cleaning liquid or air flowing out of the liquid outlet tube. Such a setting, combined with the effect of the conical expansion plate adjusting the size of the end of the liquid outlet tube, can more accurately control the speed and range of the cleaning liquid and air flowing out of the end of the liquid outlet tube, so as to process the patient's wound with different ranges and intensities according to the need, improving the cleaning and drying effects of the patient's wound.

[0042] As Figures 1 to 12As shown in the figure, an embodiment of the present invention provides an orthopedic trauma wound cleaning and nursing device, including a bracket 6. A universal wheel is fixedly connected to the bottom of the bracket 6. A liquid storage tank 5 is fixedly connected to the top of the bracket 6. A drain pipe 501 is fixedly connected to the bottom of the liquid storage tank 5. A control valve is installed on the drain pipe 501. A mounting plate 601 is fixedly connected to the middle position of the bracket 6; a positioning assembly for fixing the patient's calf, the positioning assembly is connected to the liquid storage tank 5; a cleaning mechanism for flushing and cleaning the patient's wound, the cleaning mechanism is connected to the bracket 6. The cleaning and nursing device provided in this application is mainly set for patients with calf fractures. Compared with the existing cleaning methods, by setting the positioning assembly and the cleaning mechanism in this application, the operator can clean the patient's wound alone, saving manpower and improving the efficiency of wound cleaning. Moreover, through the cooperation of the positioning assembly and the cleaning mechanism, the cleaning liquid is reasonably utilized during the cleaning process to avoid waste. In addition, after the wound cleaning is completed, the positioning assembly and the cleaning mechanism can remove and dry the remaining liquid at the patient's wound, improving the efficiency of the wound cleaning process and avoiding discomfort to the patient caused by too long cleaning time.

[0043] As an implementation manner in this embodiment, as Figures 2 to 8As shown, the positioning assembly includes a first positioning plate 1 and a second positioning plate 2 fixedly connected to the top of the liquid accumulation tank 5. A connecting plate 106 is fixedly connected to the outer side wall of the first positioning plate 1. The first positioning plate 1 and the second positioning plate 2 are fixedly connected through the connecting plate 106. A placement plate 102 is fixedly connected to the bottom of the first positioning plate 1. The width of the placement plate 102 is greater than the width of the first positioning plate 1. At the middle position of the first positioning plate 1, first elastic bending parts 101 are symmetrically installed. The first elastic bending parts 101 have an outwardly convex arc-shaped contour. The top middle position of the first positioning plate 1 is of an open structure. A plurality of guide plates 103 distributed in a circumferential array are fixedly connected to the top of the first positioning plate 1. At the connection position between the guide plate 103 and the first positioning plate 1, a second elastic bending part 104 is fixedly connected. The second elastic bending part 104 has an outwardly convex arc-shaped contour. One end of the guide plate 103 away from the first positioning plate 1 is fixedly connected with a hook plate 105. The hook plate 105 is perpendicular to the guide plate 103. A hanging rod 202 is inserted into the top of the second positioning plate 2. A drainage plate 201 is fixedly connected to the bottom of the second positioning plate 2. The drainage plate 201 has a downwardly bent arc-shaped contour. A plugging part 203 is fixedly connected to the bottom of the hanging rod 202. A jack matching the size of the plugging part is opened at the top of the second positioning plate 2. The core structure in the positioning assembly mainly includes the first positioning plate 1 and the second positioning plate 2. Both the first positioning plate 1 and the second positioning plate 2 are installed on the top of the liquid accumulation tank 5, and they are used to position and fix the two ends of the patient's calf. Specifically, the first positioning plate 1 is located on one side of the top of the liquid accumulation tank 5. The overall contour of the first positioning plate 1 is a circular contour and the top is of an open structure. Since the first elastic bending parts 101 are symmetrically installed at the middle position of the first positioning plate 1 and the first elastic bending parts 101 have an outwardly convex arc-shaped contour, the first positioning plate 1 has a certain elasticity under the action of the first elastic bending parts 101. The operator can bend the top of the first positioning plate 1 outward so that the first positioning plate 1 deforms by bending at the positions of the two first elastic bending parts 101 on both sides, so that the opening at the top of the first elastic bending parts 101 is larger, which is more convenient for the operator to place the patient's calf in the first positioning plate 1. The integrated structure setting of the first positioning plate 1 and the first elastic bending parts 101 can improve the efficiency of the operator in placing the patient's calf on the first positioning plate 1; the placement plate 102 is installed at the bottom of the first positioning plate 1. Since the width of the placement plate 102 is greater than the width of the first positioning plate 1, when the patient's calf is placed in the first positioning plate 1, the contact area between the first positioning plate 1 and the patient's calf is larger under the action of the placement plate 102, thereby improving the supporting effect of the first positioning plate 1 on the patient's calf and thus improving the comfort of the patient's calf.

[0044] The first positioning plate 1 and the second positioning plate 2 are connected together by a connecting plate 106. The connecting plate 106 is arranged on both sides of the first positioning plate 1 and the second positioning plate 2. Such a position setting enables the connecting plate 106 not to block the bottoms of the first positioning plate 1 and the second positioning plate 2, thereby ensuring that the patient's lower leg is in a suspended state between the first positioning plate 1 and the second positioning plate 2, and improving the operating space and operating vision of the operator.

[0045] The overall contour of the second positioning plate 2 is a semi-circular structure. A drainage plate 201 is installed at the bottom of the second positioning plate 2. Since the drainage plate 201 has a downwardly bent arc-shaped contour and the height of the second positioning plate 2 is less than the height of the first positioning plate 1, such a setting makes it so that when the patient's lower leg is placed between the first positioning plate 1 and the second positioning plate 2 (the patient's foot is close to the first positioning plate 1), the patient's lower leg is in a state of inclining towards the second positioning plate 2. During the cleaning process, the cleaning liquid left on the patient's lower leg will flow along the inclined lower leg of the patient to the position of the second positioning plate 2, and then under the drainage effect of the downwardly bent arc-shaped contour of the drainage plate 201, the cleaning liquid will fall into the liquid collection tank 5. Such a setting not only makes the cleaning liquid not stay on the patient's lower leg during the cleaning process, but also does not cause the cleaning liquid to flow to other parts of the patient except the lower leg during the cleaning process, improving the comfort of the patient and the recovery effect of the cleaning liquid.

[0046] A plurality of guide plates 103 arranged in a circumferential array are installed on the top of the first positioning plate 1, and a second elastic bending part 104 is fixedly connected at the connection position between the guide plate 103 and the first positioning plate 1. The second elastic bending part 104 has an outwardly convex arc-shaped contour. Such a setting enables the guide plate 103 to have an upward elastic force in the normal state. Under the action of the elastic force, the guide plate 103 inclines upwards. The inclined guide plates 103 make the circular area enclosed by the plurality of guide plates 103 arranged in a circumferential array have a larger opening. Such a setting enables the operator to place the patient's lower leg between the first positioning plate 1 and the second positioning plate 2 without being blocked by the structure of the guide plate 103, improving the efficiency and safety during the placement process of the patient's lower leg. Since a hook plate 105 is fixedly connected to the end of the guide plate 103 far from the first positioning plate 1 and the hook plate 105 is perpendicular to the guide plate 103, when the placement of the patient's lower leg is completed, the operator can press down the guide plate 103 to make the bottom of its hook plate 105 hang on the hanging rod 202 on the second positioning plate 2, and then fix the guide plate 103 by means of the elastic force of the second elastic bending part 104. After the guide plate 103 is fixed, the originally upwardly inclined guide plate 103 becomes straight.

[0047] In this embodiment, as Figures 2 to 8As shown, a handle 3 is slidably connected to the guide plate 103. A liquid outlet pipe 4 is inserted into the handle 3. A return spring 302 is fixedly connected to the outer wall of the handle 3. The return spring 302 is of a conical structure. One end of the return spring 302 away from the handle 3 is fixedly connected to a base 301. A limiting rod 303 is fixedly connected to the outer wall of the base 301. One end of the limiting rod 303 is sleeved with a pulley 305. A conical expansion plate 304 is fixedly connected to the bottom of the handle 3. The conical expansion plate 304 has a conical profile and a segmented structure at the bottom. An extrusion sleeve 306 is slidably connected to the outer wall of the conical expansion plate 304. The bottom of the extrusion sleeve 306 is of a segmented structure. Guide holes are respectively formed through the middle position and the end away from the second elastic bending part 104 of the guide plate 103. The handle 3 is slidably arranged on the guide plate 103. The handle 3 is limited and slides on the guide plate 103 through two pulleys 305. The pulleys 305 are fixed to the base 301 through two limiting rods 303. The two pulleys 305 are respectively located at the top and bottom of the guide plate 103. Such a setting makes it impossible for the handle 3 to be disengaged during the sliding process on the guide plate 103. The bottom of the handle 3 is inserted into the guide hole at the middle position of the guide plate 103. When the operator slides the handle 3, the pulleys 305 rotate at the top and bottom of the guide plate 103, and the bottom of the handle 3 slides in the guide hole. Further, the handle 3 is inserted into the middle position of the base 301, and a through hole is formed at the middle position of the base 301. The size of the through hole is larger than that of the handle 3. Since the handle 3 and the top of the base 301 are connected together by the conical return spring 302, the user can change the angle of the bottom of the handle 3 by rotating the handle 3. When the rotation of the handle 3 stops, the handle 3 will reset to the middle position of the base 301 under the elastic force of the return spring 302. Through the setting of the above structure, not only can the handle 3 slide on the guide plate 103, but also the angle of the bottom of the handle 3 can be changed by rotating the handle 3. Since the liquid outlet pipe 4 is installed in the handle 3, the angle of the liquid outlet pipe 4 can be changed by adjusting the angle of the handle 3, so as to clean the wounds at different positions. In all the above operations, the operator can completely achieve them with one hand, saving the input of human resources and improving the efficiency of wound cleaning.

[0048] Further, since the guiding holes are formed through the middle position of the guiding plate 103 and one end away from the second elastic bending portion 104, and multiple guiding plates 103 are provided, before cleaning the patient's wound, the user can first determine the specific position of the patient's wound according to the situation, and then selectively slide the handle 3 onto the corresponding guiding plate 103, so as to ensure that the cleaning liquid flowing out of the liquid outlet pipe 4 can accurately wash the wound position of the patient, avoiding waste of the cleaning liquid. Optionally, this device is used in cooperation with a hospital bed. Move this device to one side of the bed, let the patient lie on the bed with the calves placed on the device, and then the cleaning operation can be carried out. The operator can choose to let the patient lie in a prone position or a supine position according to the position of the calf injury, so as to ensure that this device can clean the wound at any position of the calf.

[0049] Furthermore, a conical expansion plate 304 is installed at the bottom of the handle 3. The conical expansion plate 304 has a conical profile and a segmented structure at the bottom. Since the liquid outlet pipe 4 is a flexible hose, when the end of the liquid outlet pipe 4 is installed in the conical expansion plate 304, the end of the liquid outlet pipe 4 will also have a conical profile (as Figure 8 shown). A squeezing sleeve 306 is slidably connected to the outer wall of the conical expansion plate 304. The bottom of the squeezing sleeve 306 is a segmented structure. The user can slide down the squeezing sleeve 306 to make it abut against the outer wall of the conical expansion plate 304, and then contract the outward-expanding conical profile of the conical expansion plate 304 by means of the squeezing action of the squeezing sleeve 306, reducing its tendency to expand outward, so as to achieve the effect of changing the size of the end of the liquid outlet pipe 4. By changing the size of the end of the liquid outlet pipe 4, the flow rate and range of the liquid flowing out of the liquid outlet pipe 4 can be changed, making it more convenient for the operator to perform local flushing and large-area cleaning of the patient's wound, improving the convenience and efficiency of wound cleaning. It is worth mentioning that the squeezing sleeve 306 is a straight cylindrical structure in its normal state. Due to the segmented structure of its end, when the squeezing sleeve 306 squeezes the conical expansion plate 304, its end will expand and deform. This setting ensures that during the process of adjusting the expansion size of the conical expansion plate 304 by means of the squeezing sleeve 306, excessive frictional damage will not be caused to the outer wall of the conical expansion plate 304, and when the end of the squeezing sleeve 306 expands and deforms, it forms a better fitting effect with the profile of the conical expansion plate 304, thus improving the adaptability and friction between the squeezing sleeve 306 and the conical expansion plate 304, preventing the squeezing sleeve 306 from sliding.

[0050] In this embodiment, as Figures 1 to 12As shown, the cleaning mechanism includes a storage tray 7 fixedly connected to the top of the mounting plate 601. The storage tray 7 and the mounting plate 601 are fixed by screws. Two storage tanks 8 are fixedly connected to the top of the storage tray 7. A piston 801 is slidably connected in the storage tank 8. A downward pressure rod 802 is fixedly connected to the middle position at the top of the piston 801. A hanging ring is fixedly connected to the end of the downward pressure rod 802. A first infusion tube 803 is fixedly connected to the bottom of one storage tank 8. A first valve 804 is installed on the first infusion tube 803. A second infusion tube 805 is fixedly connected to the bottom of the other storage tank 8. A second valve 806 is installed on the second infusion tube 805. The output ends of the first infusion tube 803 and the second infusion tube 805 converge onto the same pipe. A foot pedal 9 is fixedly connected to the bottom of the bracket 6. A chain 901 is fixedly connected to the top of the foot pedal 9. A connecting rod 902 is hung on the top of the chain 901. The top of the connecting rod 902 is of a hook-like structure. A limiting groove 602 corresponding to the position of the connecting rod 902 is formed on the mounting plate 601. The cleaning mechanism is mainly used to supply liquid to the liquid outlet pipe 4 mentioned above. Specifically, the storage tray 7 is installed on the mounting plate 601. A total of two storage tanks 8 are arranged in the storage tray 7. A cleaning liquid and air are respectively filled in these two storage tanks 8. The first infusion tube 803 is installed at the bottom of the storage tank 8 filled with the cleaning liquid, and the second infusion tube 805 is installed at the bottom of the storage tank 8 filled with air. The output ends of the first infusion tube 803 and the second infusion tube 805 converge onto the same pipe, and this pipe is communicated with the liquid outlet pipe 4. When cleaning the patient's wound, first open the first valve 804 and close the second valve 806, and then hang the top of the connecting rod 902 on the downward pressure rod 802 at the top of the storage tank 8 filled with the cleaning liquid. When the user steps on the foot pedal 9, the foot pedal 9 will pull down the chain 901, and the chain 901 drives the connecting rod 902 to move downward. Since the top of the connecting rod 902 is hung on the downward pressure rod 802, the connecting rod 902 will drive the downward pressure rod 802 to move downward together. At this time, the piston 801 slides towards the bottom of the storage tank 8, and pushes the liquid in the storage tank 8 into the first infusion tube 803, then flows into the liquid outlet pipe 4 along the first infusion tube 803, and finally flows out from the liquid outlet pipe 4 to wash the patient's wound. When it is necessary to dry the patient's wound, first close the first valve 804 and then open the second valve 806, hang the top of the connecting rod 902 on the downward pressure rod 802 at the top of the storage tank 8 filled with air, and then let the air in the storage tank 8 spray out from the liquid outlet pipe 4 by stepping on the foot pedal 9, and use the sprayed air to blow the patient's wound, blow off the cleaning liquid attached to the patient's calf, and accelerate the drying efficiency of the cleaning liquid.

[0051] Further, the user can adjust the force of stepping on the pedal 9 according to needs, so as to change the flow rate of the cleaning liquid or air flowing out of the liquid outlet pipe 4. Such a setting, combined with the effect of the conical expansion plate 304 on adjusting the size of the end of the liquid outlet pipe 4, can more accurately control the flow rate and range of the cleaning liquid and air flowing out of the end of the liquid outlet pipe 4, so as to process the patient's wound in different ranges and with different forces according to needs, and improve the cleaning and drying effects of the patient's wound.

[0052] The working principle of the technical solution provided by the present invention is as follows:

[0053] When it is necessary to flush and clean the wound on the patient's calf, first place the patient's calf between the first positioning plate 1 and the second positioning plate 2. The operator first bends the top of the first positioning plate 1 outwards, so that the first positioning plate 1 undergoes a bending deformation at the position of the first elastic bending part 101 on both sides, so that the opening at the top of the first elastic bending part 101 is larger, making it more convenient for the operator to place the patient's calf in the first positioning plate 1. A placement plate 102 is installed at the bottom of the first positioning plate 1. Since the width of the placement plate 102 is greater than the width of the first positioning plate 1, when the patient's calf is placed in the first positioning plate 1, the contact area between the first positioning plate 1 and the patient's calf is larger due to the action of the placement plate 102, thereby improving the support effect of the first positioning plate 1 on the patient's calf and thus improving the comfort of the patient's calf. After the patient's calf is placed, the user selectively slides the handle 3 onto the corresponding guide plate 103 according to the specific position of the patient's wound, and then presses down the guide plate 103 so that the bottom of its hook plate 105 is hooked onto the hanging rod 202 on the second positioning plate 2, and then the guide plate 103 is fixed by means of the elastic force of the second elastic bending part 104. When the guide plate 103 is fixed, the originally upwardly inclined guide plate 103 becomes straight.

[0054] When cleaning the patient's wound, first open the first valve 804 and close the second valve 806. Then, hang the top of the connecting rod 902 on the pressing rod 802 at the top of the cleaning liquid storage tank 8. When the user steps on the foot pedal 9, the foot pedal 9 will pull down the chain 901, and the chain 901 drives the connecting rod 902 to move downward. Since the top of the connecting rod 902 is hung on the pressing rod 802, the connecting rod 902 will drive the pressing rod 802 to move downward together. At this time, the piston 801 slides towards the bottom of the storage tank 8 and pushes the liquid in the storage tank 8 into the first infusion tube 803, then flows into the liquid outlet tube 4 along the first infusion tube 803, and finally flows out from the liquid outlet tube 4 to wash the patient's wound. The liquid outlet tube 4 is fixed in the grip 3, and the grip 3 is limited and slides on the guide plate 103 through two pulleys 305. The pulleys 305 are fixed on the base 301 through two limiting rods 303. The two pulleys 305 are respectively located at the top and bottom of the guide plate 103. Such a setting makes the grip 3 not detach during the sliding process on the guide plate 103. By sliding the grip 3, the position of the liquid outlet tube 4 can be changed, thereby changing the washing position of the patient's wound. The grip 3 is inserted into the middle position of the base 301, and a through hole is opened at the middle position of the base 301. The size of the through hole is larger than the size of the grip 3. Since the grip 3 and the top of the base 301 are connected together by a return spring 302 with a tapered profile, the user can change the angle of the bottom of the grip 3 by rotating the grip 3. When the rotation of the grip 3 stops, the grip 3 will reset to the middle position of the base 301 under the elastic force of the return spring 302. Through the setting of the above structure, not only can the grip 3 slide on the guide plate 103, but also the angle of the bottom of the grip 3 can be changed by rotating the grip 3, and the angle of the liquid outlet tube 4 can be changed by adjusting the angle of the grip 3, so as to clean the wounds at different positions. In all the above operations, the operator can completely achieve them with one hand, saving the input of human resources and improving the efficiency of wound cleaning. Since the height of the second positioning plate 2 is less than the height of the first positioning plate 1, such a setting makes it that when the patient's calf is placed between the first positioning plate 1 and the second positioning plate 2, the patient's calf is in a state of tilting towards the second positioning plate 2. During the cleaning process, the cleaning liquid left on the patient's calf will flow along the tilted calf of the patient to the position of the second positioning plate 2, and then under the drainage effect of the downwardly bent arc-shaped profile of the drainage plate 201, the cleaning liquid will fall into the liquid collecting tank 5. Such a setting not only makes the cleaning liquid not stay on the patient's calf during the cleaning process, but also does not cause the cleaning liquid to flow to other parts of the patient except the calf during the cleaning process, improving the comfort of the patient and the recovery effect of the cleaning liquid.

[0055] When it is necessary to dry the patient's wound, first close the first valve 804 and then open the second valve 806. Hang the top of the connecting rod 902 on the pressing rod 802 mounted on the top of the air storage tank 8. Then step on the foot pedal 9 to make the air in the storage tank 8 spray out from the liquid outlet pipe 4, and use the sprayed air to blow the patient's wound, blowing away the cleaning liquid attached to the patient's calf and accelerating the drying efficiency of the cleaning liquid. Since the bottom of the grip 3 is equipped with a conical expansion plate 304, the conical expansion plate 304 has a conical profile and the bottom is a segmented structure. Install the end of the liquid outlet pipe 4 inside the conical expansion plate 304, and the end of the liquid outlet pipe 4 will also have a conical profile. The user can slide down the extrusion sleeve 306 to make it contact the outer wall of the conical expansion plate 304, and then use the extrusion effect of the extrusion sleeve 306 to contract the outward-expanding conical profile of the conical expansion plate 304, making its outward-expanding trend smaller, so as to achieve the effect of changing the size of the end of the liquid outlet pipe 4. The user can adjust the force of stepping on the foot pedal 9 according to needs, so as to change the flow rate of the cleaning liquid or air flowing out from the liquid outlet pipe 4. Combining with the effect of the conical expansion plate 304 on adjusting the size of the end of the liquid outlet pipe 4, the flow rate and range of the cleaning liquid and air flowing out from the end of the liquid outlet pipe 4 can be controlled more precisely, so as to process the patient's wound in different ranges and strengths according to needs, and improve the cleaning and drying effects of the patient's wound.
