Description

Technical Field

[0001] This invention belongs to the field of refrigeration equipment technology, and more specifically, relates to a wound cleaning and nursing device and method for operating room care. Background Technology

[0002] In the field of operating room nursing, wound debridement devices are considered crucial specialized medical equipment. They play a vital role in removing various harmful substances from wounds and aiding in wound healing. Specifically, they can precisely and efficiently remove foreign objects, necrotic tissue, and contaminants from wounds. The device's core function is powerful and unique, integrating physical, chemical, and biological methods. Through meticulous operation, it accurately locates and removes inactive tissue that hinders normal wound repair, minimizing secondary damage to the wound. Simultaneously, it cleverly preserves healthy tissue to the maximum extent possible, maintaining the normal physiological structure and function of the wound periphery. Wounds treated with these devices are cleaner, creating extremely favorable conditions for subsequent treatments such as suturing and skin grafting, significantly improving the quality and speed of wound healing.

[0003] While wound cleaning devices play a crucial role in current operating room nursing practices, they also have significant shortcomings. When medical staff use these devices to perform wound cleaning on patients, they often need to alternate between clean water and disinfectant to complete different stages of the procedure. For example, they might first use clean water to initially rinse the wound and remove visible surface dirt, and then use disinfectant for deep sterilization. However, this operating mode forces medical staff to frequently change equipment or repeatedly adjust device settings, which not only increases the complexity of the operation but also seriously reduces overall work efficiency and hinders the smooth progress of operating room nursing procedures. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes a wound cleaning and nursing device and method for operating room care, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a wound cleaning and nursing device for operating room care, comprising a mobile cart as the basic support for the entire device. A lifting mechanism is cleverly designed above the cart, precisely controlling the up-and-down movement of a support plate to meet the needs of wound cleaning at different heights and angles. A wastewater basket is movably installed on the support plate to facilitate the collection of wastewater generated during wound cleaning, maintaining a clean surgical environment. Simultaneously, two ergonomically designed support frames are fixedly mounted on the support plate to stably place the patient's limbs, ensuring smooth wound cleaning. Above the support plate, a sliding lifting base is flexibly adjusted in height to accommodate different patients' needs. A medicine tank and a disinfection tank are fixedly installed above the lifting base, connected at both ends by a three-way pipe for convenient switching between medicine and disinfectant solutions. The connecting pipe in the middle of the three-way valve is connected to a wound cleaning mechanism. This mechanism includes a connecting frame fixedly mounted on a lifting base. A water outlet is fixedly connected inside the connecting frame, serving as the outlet for medication and disinfectant. The connecting pipe in the middle of the three-way valve is tightly connected to one end of the water outlet, while the other end of the water outlet is fixedly connected to a first connecting pipe. The first connecting pipe is further fixedly connected to a rotating disk, which is rotatably mounted on the connecting frame, allowing the wound cleaning head to rotate at multiple angles. A connecting piece is fixedly connected above the rotating disk, and above the connecting piece are a water spray head and a misting nozzle. The water spray head is used to directly rinse the wound, while the misting nozzle is used to spray disinfectant, achieving comprehensive wound cleaning care. The water spray head is fixedly connected to the first connecting pipe, and the misting nozzle is fixedly connected to a second connecting pipe, which is also fixedly connected to the bottom of the rotating disk. The connector is located inside the baffle plate to effectively prevent the medicine from splashing. In addition, both ends of the tee are equipped with sealing mechanisms. These mechanisms are precisely designed to prevent the convection and outflow of liquid in the medicine tank and the disinfection tank, ensuring the stability and safety of the wound cleaning process.

[0006] Furthermore, a filter screen is installed inside the wastewater frame to effectively filter impurities in the wastewater, facilitating subsequent treatment. The support frame is made of medical-grade rubber, which is soft and comfortable, reducing pressure on the patient's limbs. The sealing mechanism includes a cross-shaped component fixedly installed inside the three-way pipe. One end of the cross-shaped component is fixedly mounted with a return spring, and the other end of the return spring is fixedly mounted on a sealing ball. The sealing ball has a larger area than the outlet, which is located on a sealing plate fixedly installed inside the three-way pipe. When the liquid medicine or disinfectant flows, the sealing ball moves away from the outlet under pressure, allowing the liquid to flow; when the flow stops, the sealing ball re-seals the outlet under the action of the return spring, preventing liquid convection and outflow.

[0007] Furthermore, a sliding groove is provided above the support plate, and a first threaded rod is rotatably installed inside the sliding groove. The first threaded rod is threadedly connected to a lifting base frame. By rotating the first threaded rod, the lifting base frame can slide within the sliding groove, thereby adjusting the height of the debridement mechanism. One end of the first threaded rod is fixedly installed with the output end of a micro motor, which provides power to achieve automated adjustment of the lifting base frame.

[0008] Furthermore, the connecting frame has an arc-shaped groove, through which a limit rod is slidably connected. The limit rod is fixedly installed at the bottom of the rotating disk to limit the rotation angle of the rotating disk, ensuring the stability and accuracy of the cleaning head. The distance between the first and second connecting pipes is the distance the limit rod rotates along the inside of the arc-shaped groove. This design ensures that the cleaning head is not interfered with by the tubing during rotation.

[0009] Furthermore, the lifting mechanism includes a first connecting rod fixedly mounted on the mobile frame, with a second threaded rod rotatably mounted inside the first connecting rod. The second threaded rod is threadedly connected to the second connecting rod, and the second connecting rod is slidably connected inside the first connecting rod. By rotating the second threaded rod, the second connecting rod can slide up and down within the first connecting rod, thereby driving the lifting and lowering of the support plate.

[0010] Furthermore, four of each of the first connecting rod, second connecting rod, and second threaded rod are provided, and each of the four second threaded rods is fixedly equipped with a worm gear. The four worm gears are arranged in pairs, and each pair of worm gears is engaged with a worm. There are two worms, and each worm is fixedly equipped with a drive wheel, which is connected by a drive belt. One of the worms is fixedly equipped with the output end of a drive motor, which is fixedly mounted on the mobile frame. When the drive motor starts, it drives the two worms to rotate synchronously via the drive belt, thereby driving the four worm gears and the second threaded rods to rotate, achieving smooth lifting and lowering of the support plate.

[0011] Furthermore, the wastewater frame is fixedly connected to a wastewater tank via a sewage pipe. The wastewater tank is fixedly mounted on a mobile frame for collecting and storing wastewater. The bottom of the mobile frame is fixedly equipped with casters that are self-locking, facilitating the movement and securing of the device. This design allows the wound cleaning and nursing device to be flexibly positioned within the operating room to meet the needs of different surgical areas.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This device is equipped with a lifting mechanism. A drive motor rotates the worm gear and worm wheel, causing the four second threaded rods to rotate synchronously. This allows the second connecting rod to slide smoothly within the first connecting rod, precisely adjusting the height of the support plate to meet the needs of different patients' heights and nursing requirements. Simultaneously, the lifting base above the support plate can be driven by a micro-motor to rotate the first threaded rod, achieving height adjustment and facilitating the repositioning of the wound cleaning mechanism to be closer to the patient's wound. Furthermore, the rotating disc can rotate on the connecting frame, flexibly adjusting the angle of the water spray head and atomizing nozzle, facilitating the care of different wound areas and greatly improving operational flexibility and precision.

[0013] 2. The three-way tube has internal sealing mechanisms at both ends, consisting of a cross, a return spring, a sealing ball, and a sealing plate. When the disinfectant solution flows from the solution tank into the three-way tube, the sealing ball inside the disinfection tank seals the outlet under the action of the return spring, preventing the disinfectant solution from flowing out. Similarly, when the disinfectant solution flows out of the disinfection tank, the sealing mechanism inside the solution tank prevents the solution from flowing out. When the supply of solution stops, the return spring pushes the sealing ball to reseal the outlet, preventing backflow or leakage, ensuring that only pure disinfectant solution enters the spray head and only pure disinfectant solution enters the atomizing nozzle, thus guaranteeing the quality and safety of wound cleaning and care.

[0014] 3. The support frame is made of medical-grade rubber, which is soft, elastic, non-toxic, and odorless, effectively reducing pressure on the patient's limbs and improving patient comfort. An adjustable filter screen is installed inside the wastewater container to pre-filter the collected wastewater, removing larger impurities for easier subsequent wastewater treatment. The mobile cart is equipped with self-locking casters at the bottom, allowing for easy movement and locking of the device to prevent movement during care. This facilitates wound cleaning and nursing procedures, demonstrating the device's practicality and user-friendly design.

[0015] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0021] Please see Figures 1-7As shown, this invention is a wound cleaning and nursing device for operating room care, including a mobile carriage 1. A lifting mechanism is installed above the mobile carriage 1. The main function of the lifting mechanism is to precisely control the up-and-down movement of a support plate 2 to meet the adjustment needs of the patient's limb height in different nursing scenarios. A wastewater frame 3 is movably installed on the support plate 2 to collect wastewater generated during the nursing process, preventing contamination of the surgical environment. Simultaneously, two support frames 4 are fixedly installed on the support plate 2. These two support frames 4 are specifically used to place the patient's limb, ensuring the patient maintains a comfortable and stable posture during wound cleaning and nursing. Above the support plate 2, a lifting base frame 5 is slidably installed, and a medicine tank 6 and a sterilization tank 7 are fixedly installed above the lifting base frame 5. The medicine tank 6 and the sterilization tank 7 are connected through the two ends of a three-way pipe 8, and the connecting pipe in the middle of the three-way pipe 8 is connected to the wound cleaning mechanism. The wound cleaning mechanism includes a connecting frame 9 fixedly mounted on a lifting base 5. A water outlet 10 is fixedly connected inside the connecting frame 9. A connecting pipe in the middle of a three-way pipe 8 connects to one end of the water outlet 10, and the other end of the water outlet 10 is fixedly connected to a first connecting pipe 11. The first connecting pipe 11 is fixedly connected to a rotating disk 12, which is rotatably mounted on the connecting frame 9. This design allows the rotating disk 12 to rotate flexibly, thereby adjusting the angle of the wound cleaning nozzle. A connecting piece 13 is fixedly connected above the rotating disk 12. A water spray head 14 and an atomizing nozzle 15 are fixedly connected above the connecting piece 13. The water spray head 14 is fixedly connected to the first connecting pipe 11 and is used to spray a large flow of cleaning water for initial rinsing of the wound. The atomizing nozzle 15 is fixedly connected to a second connecting pipe 16, which is fixedly connected to the bottom of the rotating disk 12. The atomizing nozzle 15 can spray a fine atomized medicinal solution for disinfection of the wound. The connecting piece 13 is located inside a baffle plate 17 to prevent the medicinal solution from splashing. In addition, both ends of the three-way pipe 8 are equipped with sealing mechanisms, which can effectively prevent the liquid in the medicine tank 6 and the disinfection tank 7 from convection and outflow, ensuring the purity of the medicine and disinfectant.

[0022] The working principle of the wound cleaning and nursing device for operating room care proposed in this invention is as follows: when performing wound cleaning and nursing work in the operating room, the device is first pushed to a suitable position. Using a lifting mechanism, the height of the support plate 2 is precisely adjusted to achieve a position suitable for caring for the patient's limb.

[0023] Place the patient's limbs securely on the two fixed support frames 4 on the support plate 2, allowing the patient to maintain a comfortable and stable posture. At this time, the wastewater frame 3 installed on the support plate 2 is ready to collect wastewater.

[0024] The lifting base 5 above the sliding support plate 2 is used to adjust the debridement mechanism to a suitable position so that it is close to the patient's wound.

[0025] When initial rinsing of the wound is required, first rotate the rotating disk 12 to accurately connect the first connecting pipe 11 to the water outlet 10. The medication flows from the medication tank 6, enters the three-way pipe 8 through the end connected to the medication tank 6, then flows through the connecting pipe in the middle of the three-way pipe 8 into one end of the water outlet 10 fixedly connected inside the connecting frame 9, and then flows through the first connecting pipe 11 to the rotating disk 12. Finally, a large flow of cleaning water is sprayed from the spray head 14 on the fixedly connected connector 13 above the rotating disk 12 to rinse the wound. During this process, the sealing mechanism inside both ends of the three-way pipe 8 functions to prevent convection and outflow of the disinfectant in the disinfection tank 7, ensuring that only pure medication enters the spray head 14. Wastewater generated during rinsing flows into the wastewater frame 3.

[0026] When wound disinfection is required, rotate the rotating disc 12 to connect the second connecting pipe 16 to the water outlet 10. Disinfectant flows from the disinfection tank 7, enters the three-way pipe 8 through the end connected to the disinfection tank 7, then flows through the connecting pipe in the middle of the three-way pipe 8 into one end of the water outlet 10 fixedly connected inside the connecting frame 9, and then flows through the second connecting pipe 16 connected to it to the rotating disc 12. Finally, it is sprayed out as a fine atomized disinfectant solution through the atomizing nozzle 15 on the connecting piece 13 fixedly connected above the rotating disc 12 to disinfect the wound. Similarly, the sealing mechanism inside both ends of the three-way pipe 8 prevents convection and outflow of the disinfectant solution in the medicine tank 6, ensuring that only pure disinfectant solution enters the atomizing nozzle 15. Wastewater generated during the disinfection process also flows into the wastewater frame 3.

[0027] During rinsing or disinfection, the angle of the wound cleaning nozzles (spray nozzles 14 and atomizing nozzles 15) can be flexibly adjusted by rotating the rotating disc 12 mounted on the connecting frame 9, so as to better care for different parts of the wound. The connector 13 is located inside the baffle plate 17, which can effectively prevent the medicine from splashing.

[0028] In one embodiment, the wastewater frame 3 is equipped with a filter screen 18, which performs preliminary filtration of the collected wastewater, removing larger impurities and facilitating subsequent wastewater treatment. The support frame 4 is made of medical-grade rubber, which is soft, elastic, non-toxic, and odorless, reducing pressure on the patient's limbs and improving patient comfort. The sealing mechanism includes a cross 34 fixedly installed inside the three-way pipe 8. One end of a return spring 35 is fixedly installed on the cross 34, and the other end of the return spring 35 is fixedly installed on a sealing ball 36. The sealing ball 36 has a larger area than the outlet 37, which is located on a sealing plate 38 fixedly installed inside the three-way pipe 8. When the medicine or disinfectant needs to flow out, the pressure of the liquid overcomes the elasticity of the return spring 35, pushing open the sealing ball 36 and allowing the liquid to flow out from the outlet 37. When the liquid supply stops, the return spring 35 pushes the sealing ball 36 to reseal the outlet 37, preventing backflow or leakage.

[0029] The working principle of the wound cleaning nursing device proposed in this invention for operating room care is as follows: when performing wound cleaning nursing operations in the operating room, the wound cleaning nursing device is first moved to a suitable position, and the support plate 2 is precisely adjusted to a suitable height using the lifting mechanism to meet the height requirements of the patient's limbs in different nursing scenarios.

[0030] The patient's limbs are securely placed on two medical-grade rubber supports 4 fixedly mounted on the support plate 2. This material is soft, elastic, non-toxic, and odorless, effectively reducing pressure on the patient's limbs and improving patient comfort. At this time, the wastewater frame 3, movably mounted on the support plate 2, is in a wastewater collection state. The internally mounted filter screen 18 can perform preliminary filtration of the collected wastewater, removing larger impurities to facilitate subsequent wastewater treatment.

[0031] The lifting base 5 above the sliding support plate 2 is used to adjust the position of the debridement mechanism so that it is close to the patient's wound.

[0032] When initial rinsing of the wound with the disinfectant solution is required, the water pump built into the disinfectant tank 6 is activated to start the flow of the solution. The solution flows out of the tank 6 and enters the three-way pipe 8 through the end connected to the tank 6. During this process, the sealing mechanism inside another disinfection box 7 is in a sealed state. This sealing mechanism is a cross 34 fixedly installed inside the three-way pipe 8. One end of a return spring 35 is fixedly installed on the cross 34, and the other end of the return spring 35 is fixed to a sealing ball 36. The area of ​​the sealing ball 36 is larger than the outlet 37 opened on the sealing plate 38 fixedly installed inside the three-way pipe 8. At this time, the sealing ball 36 seals the outlet 37 under the action of the return spring 35, preventing the disinfectant solution from flowing out. After the solution flows into the three-way pipe 8, the liquid pressure overcomes the elastic force of the return spring 35, pushes open the sealing ball 36, and allows the solution to flow out from the outlet 37. Then, it flows through the connecting pipe in the middle of the three-way pipe 8 into one end of the water outlet 10 fixedly connected inside the connecting frame 9. Next, the rotating disk 12 is rotated to accurately connect the first connecting pipe 11 to the water outlet 10. The medicine flows through the first connecting pipe 11 to the rotating disk 12, and finally, a large flow of cleaning water is sprayed out through the spray head 14 on the fixed connecting piece 13 above the rotating disk 12 to rinse the wound. The wastewater generated during rinsing flows into the wastewater frame 3 and is initially filtered by the filter screen 18. When the supply of medicine is stopped, the reset spring 35 pushes the sealing ball 36 to reseal the outlet 37 to prevent the medicine from flowing back or leaking.

[0033] When wound disinfection is required, the built-in water pump of the disinfection tank 7 is activated to start the flow of disinfectant. The disinfectant flows out of the disinfection tank 7 and enters the three-way pipe 8 through the end connected to the disinfection tank 7. At this time, the sealing mechanism inside the medicine tank 6 is in a sealed state, and its working principle is the same as that of the sealing mechanism of the disinfection tank 7. The sealing ball 36, under the action of the return spring 35, seals the outlet 37 to prevent the medicine from flowing out. After the disinfectant flows into the three-way pipe 8, the liquid pressure overcomes the elastic force of the return spring 35, pushing open the sealing ball 36, allowing the disinfectant to flow out from the outlet 37, and then through the connecting pipe in the middle of the three-way pipe 8 into one end of the fixedly connected water outlet 10 inside the connecting frame 9. Next, the rotating disk 12 is rotated to connect the second connecting pipe 16 to the water outlet 10. The disinfectant flows through the second connecting pipe 16 to the rotating disk 12, and finally, a fine atomized medicine is sprayed out through the atomizing nozzle 15 on the fixedly connected connector 13 above the rotating disk 12 to disinfect the wound. Wastewater generated during the disinfection process also flows into wastewater container 3 and is filtered. When the supply of disinfectant is stopped, the reset spring 35 pushes the sealing ball 36 to reseal the outlet 37, preventing the disinfectant from flowing back or leaking.

[0034] During rinsing or disinfection, the rotating disc 12 mounted on the connecting frame 9 can be rotated to flexibly adjust the angle of the wound cleaning nozzles (water spray head 14 and atomizing nozzle 15) for better care of different parts of the wound. The connector 13 is located inside the baffle plate 17 to effectively prevent splashing of medicine.

[0035] In one embodiment, the support plate 2 has a groove 19 on its upper surface. A first threaded rod 20 is rotatably mounted inside the groove 19. The first threaded rod 20 is threadedly connected to a lifting base frame 5, and the output end of a micro motor is fixedly mounted at one end of the first threaded rod 20. When the micro motor starts, it drives the first threaded rod 20 to rotate. Since the lifting base frame 5 is threadedly connected to the first threaded rod 20 and is constrained by the groove 19, the lifting base frame 5 slides up and down along the groove 19, thereby achieving height adjustment of the lifting base frame 5 to meet the needs of different nursing operations.

[0036] In one embodiment, the connecting frame 9 has an arc-shaped groove 22, which is slidably connected to a limiting rod 23, which is fixedly installed at the bottom of the rotating disk 12. The distance between the first connecting pipe 11 and the second connecting pipe 16 is the distance the limiting rod 23 rotates along the inside of the arc-shaped groove 22. This design allows the limiting rod 23 to slide within the arc-shaped groove 22 during the rotation of the rotating disk 12. When the limiting rod 23 reaches both ends of the arc-shaped groove 22, it restricts further rotation of the rotating disk 12, thereby ensuring that the rotation angle of the wound cleaning nozzle is within a safe range and avoiding damage to the equipment due to excessive rotation angle.

[0037] In one embodiment, the lifting mechanism includes a first connecting rod 24 fixedly mounted on the mobile frame 1. A second threaded rod 25 is rotatably mounted inside the first connecting rod 24. The second threaded rod 25 is threadedly connected to a second connecting rod 26, which is slidably connected inside the first connecting rod 24. By rotating the second threaded rod 25, the second connecting rod 26 can slide up and down within the first connecting rod 24, thereby adjusting the height of the support plate 2 to accommodate the height and care needs of different patients.

[0038] In one embodiment, four of each of the aforementioned first connecting rod 24, second connecting rod 26, and second threaded rod 25 are provided. Each of the four second threaded rods 25 is fixedly equipped with a worm gear 39, arranged in pairs. This symmetrical design ensures the stability of the support plate 2 during lifting. The fixed installation of worm gears 39 on each of the four second threaded rods 25, with the worm gears 39 arranged in pairs, facilitates the subsequent rotation of the worm gears 39 via the worm 27, thereby achieving synchronous rotation of the four second threaded rods 25.

[0039] In one embodiment, for the aforementioned worm gears 39, both sets of worm gears 39 are meshed with worms 27. There are two worms 27, and each worm 27 is fixedly mounted with a transmission wheel 28. The two transmission wheels 28 are connected by a transmission belt 29. One of the worms 27 is fixedly mounted with the output end of a drive motor 30, which is fixedly mounted on the mobile frame 1. When the drive motor 30 starts, it drives one of the worms 27 to rotate. This worm 27 drives the other worm 27 to rotate synchronously through the transmission wheel 28 and the transmission belt 29. The two worms 27 drive the two sets of worm gears 39 to rotate, thereby causing the four second threaded rods 25 to rotate synchronously, achieving the smooth lifting and lowering of the support plate 2.

[0040] In one embodiment, the wastewater frame 3 is fixedly connected to a wastewater tank 32 via a sewage pipe 31. The wastewater tank 32 is fixedly mounted on the mobile frame 1. This design facilitates the centralized storage and treatment of collected wastewater. The bottom of the mobile frame 1 is fixedly equipped with casters 33, which are self-locking. Medical personnel can easily push the device to a designated location and secure it using the self-locking function to prevent movement during nursing care, ensuring the smooth progress of nursing work.

[0041] The working principle of the wound cleaning nursing device proposed in this invention is as follows: when performing wound cleaning nursing work in the operating room, the device is first easily pushed to the designated position and locked by the self-locking casters 33 fixedly installed at the bottom of the mobile frame 1 to prevent the device from moving during the nursing process.

[0042] When adjusting the height of the support plate 2 to accommodate different patient heights and nursing needs, the drive motor 30, fixedly mounted on the mobile frame 1, is activated. The output of the drive motor 30 drives one of the worm gears 27 to rotate. The transmission wheel 28 fixedly mounted on the worm gear 27 drives the other worm gear 27 to rotate synchronously via the transmission belt 29. The two worm gears 27 drive two sets of worm wheels 39 to rotate respectively. Since all four second threaded rods 25 are fixedly mounted with worm wheels 39, and the four worm wheels 39 are arranged in pairs, the four second threaded rods 25 can rotate synchronously. The second threaded rods 25 are threadedly connected to the second connecting rods 26. The second connecting rods 26 are slidably connected inside the first connecting rod 24 fixedly mounted on the mobile frame 1. By rotating the second threaded rods 25, the second connecting rods 26 slide up and down within the first connecting rod 24, thereby achieving the smooth raising and lowering of the support plate 2.

[0043] A sliding groove 19 is provided above the support plate 2. A first threaded rod 20 is rotatably installed inside the sliding groove 19. The output end of a micro motor is fixedly installed at one end of the first threaded rod 20, and the first threaded rod 20 is threadedly connected to the lifting base frame 5. When it is necessary to adjust the height of the lifting base frame 5 to meet different nursing operation needs, the micro motor is started, driving the first threaded rod 20 to rotate. Since the lifting base frame 5 is threadedly connected to the first threaded rod 20 and is restricted by the sliding groove 19, the lifting base frame 5 will slide up and down along the sliding groove 19 to achieve height adjustment.

9. The method of using a wound cleaning and nursing device in operating room care according to claim 1, characterized in that, Includes the following steps: Step 1: When performing debridement and nursing work in the operating room, first push the debridement and nursing device to a suitable position, and use the lifting mechanism to precisely adjust the height of the support plate (2) to make it suitable for nursing the patient's limbs. Place the patient's limbs securely on the two support frames (4) fixedly installed on the support plate (2) to keep the patient in a comfortable and stable position. At this time, the wastewater frame (3) installed on the support plate (2) is ready to collect wastewater. Step 2: Slide the lifting base frame (5) above the support plate (2) and adjust the debridement mechanism to a suitable position so that it is close to the patient's wound; Step 3: When the wound needs to be initially rinsed, first rotate the rotating disk (12) to accurately connect the first connecting pipe (11) with the water outlet (10). The medicine flows out from the medicine tank (6), enters the three-way pipe (8) through the end connected to the medicine tank (6) at both ends, and then flows into the water outlet (10) fixedly connected inside the connecting frame (9) through the connecting pipe in the middle of the three-way pipe (8). Then it flows to the rotating disk (12) through the first connecting pipe (11) connected to it. Finally, a large flow of cleaning water is sprayed out through the spray head (14) on the fixedly connected connector (13) above the rotating disk (12) to rinse the wound. During this period, the sealing mechanism set inside both ends of the three-way pipe (8) plays a role in preventing the disinfectant in the disinfection box (7) from convection and outflow, ensuring that the medicine entering the spray head (14) is pure medicine. The wastewater generated by rinsing flows into the wastewater frame (3). Step 4: When it is necessary to disinfect the wound, rotate the rotating disk (12) to connect the second connecting pipe (16) with the water outlet (10). The disinfectant flows out from the disinfection box (7), enters the three-way pipe (8) through the end connected to the disinfection box (7) at both ends, and then flows into the water outlet (10) fixedly connected inside the connecting frame (9) through the connecting pipe in the middle of the three-way pipe (8). Then it flows to the rotating disk (12) through the second connecting pipe (16) connected to it. Finally, it sprays out fine atomized medicine through the atomizing nozzle (15) on the connecting piece (13) fixedly connected above the rotating disk (12) to disinfect the wound. Similarly, the sealing mechanism inside both ends of the three-way pipe (8) prevents the medicine in the medicine tank (6) from convection and outflow, ensuring that the medicine entering the atomizing nozzle (15) is pure disinfectant. The wastewater generated during the disinfection process also flows into the wastewater frame (3). Step 5: During rinsing or disinfection, the angles of the spray head (14) and the atomizing nozzle (15) can be flexibly adjusted by rotating the rotating disc (12) installed on the connecting frame (9) so as to better care for different parts of the wound. The connector (13) is set inside the baffle plate (17) to effectively prevent the medicine from splashing.
