[0040] As Figure 4 And Figure 5As shown, the outer part of the ring-shaped frame 1 is provided with a limiting component for driving the arc-shaped connecting frame 18 to move. The limiting component includes a plurality of connecting plates 13 arranged on the outer wall of the ring-shaped frame 1, and the inner side wall of each connecting plate 13 is fixedly connected with two groups of first limiting slide rods 15 respectively. One end of each group of first limiting slide rods 15 penetrates through the inner side of the ring-shaped frame 1 and is fixedly connected with the outer wall of one arc-shaped connecting frame 18 respectively. The outer wall of the ring-shaped frame 1 is rotationally connected with a lead screw 16, one end of the lead screw 16 penetrates through the outer part of the connecting plate 13 and is threadedly connected with the connecting plate 13, and one end of the lead screw 16 is fixedly connected with a rocker 14.
[0041] As shown in Figure 6 The fitting mechanism includes a second air bag 23 mounted on the inner side of the ring-shaped frame 1. The inner side of the ring-shaped frame 1 is fixedly connected with a second fixed pipeline 7. The first air outlet end of the second fixed pipeline 7 is in communication with the air inlet end of the second air bag 23. The second air outlet end of the second fixed pipeline 7 is provided with a pressure relief valve 8. The air inlet end of the second fixed pipeline 7 is provided with a first one-way valve 9. The air inlet end of the first one-way valve 9 is provided with a first air bag 10. The air inlet end of the first air bag 10 is provided with a second one-way valve 11.
[0042] As shown in Figure 2 The water conveying channel 3 is externally connected with a water pump through a communication hose. The water pump draws clean water into the water conveying channel 3 and then out through the first fixed pipeline 4, so as to wet the wiping cloth 5.
[0043] The outer wall of the handle 12 is provided with a first PLC controller for controlling the start and stop of the pressure relief valve 8. The first PLC controller is provided with a start and stop button.
[0044] First, the medical staff rotates the rocker 14 by hand to drive the lead screw 16 to rotate on the outer wall of the ring-shaped frame 1, so that the connecting plate 13 drives the two groups of first limiting slide rods 15 on the inner side to move towards the inner side of the ring-shaped frame 1, and the two groups of first limiting slide rods 15 drive the plurality of first clamping rollers 25 on the inner side of the two arc-shaped connecting frames 18 to move towards the center of the ring-shaped frame 1. When the lead screw 16 is twisted to the maximum limit, the first clamping roller 25 is butt jointed with the second clamping roller 26, clamping the two side edges of the wiping cloth 5 in the middle. Then, the remaining lead screws 16 are repeatedly operated, so as to limit the edges of the wiping cloth 5, avoid displacement and wrinkles caused by self-weight sagging, water flow impact or wiping friction after the wiping cloth 5 is wetted by water, lay a foundation for subsequent work, and improve the overall practicability of the equipment.
[0045] Then the medical staff holds the handle 12, lifts the lower limbs of the patient towards the face, puts the feet into the fixed plate 2, and simply fixes the lower limbs of the patient, so that the lower limbs form an obtuse angle with the upper body, moves the fixed plate 2 to the thigh position, and then the medical staff repeatedly presses the first air bag 10, air is sucked into the second one-way valve 11, and then enters the second air bag 23 from the first one-way valve 9 through the second fixed pipeline 7, so that the second air bag 23 expands, the part of the second air bag 23 that expands pushes the inner side of the wiping cloth 5 from the outer wall of the wiping cloth 5 to the skin of the thigh of the patient, so that the wiping cloth 5 can be attached to the skin of the lower limbs of the patient, the second air bag 23 expands by inflation to generate a flexible pushing force, and the wiping cloth 5 is pushed from the outer wall of the wiping cloth 5 to the skin of the patient, and the elastic deformation characteristics of the air bag are used to adapt to the curved contour of the thigh of the patient, such as muscle lines, limb thickness differences, so that the wiping cloth 5 fully covers the skin surface, eliminates the problem of "partial suspension and poor adhesion" in traditional manual wiping, ensures that there is no gap between the wiping cloth 5 and the skin, thereby improving the effect during wiping, and further improving the work efficiency of the medical staff;
[0046] In the process of pushing the wiping cloth 5 to adhere to the skin of the lower limbs of the patient by the second air bag 23, the two side edges of the wiping cloth 5 will be shrunk to the center, and since the first clamping roller 25 and the second clamping roller 26 clamp the two sides of the wiping cloth 5, at this time, the first clamping roller 25 inside the multiple sets of arc-shaped connecting frames 18 on the two side edges of the wiping cloth 5 moves relatively under the action of the second spring 34 and the third fixed seat 24, and continues to limit the two side edges of the wiping cloth 5, the relative movement of the clamping roller does not need manual operation intervention, and can automatically adapt to different shrinkage amplitudes, so that the limiting function is synchronized with the adhesion process, the medical staff does not need to adjust the wiping cloth 5 in the middle, significantly improves the operation continuity and operation convenience, and thereby improves the work efficiency of the medical staff;
[0047] When the wiping cloth 5 is attached to the skin of the lower limbs of the patient, the medical staff presses the first air bag 10 again, since the lower limbs of the patient block the second air bag 23 from expanding, and the gas in the second air bag 23 continues to increase the pressure, when the pressure value of the air inlet of the pressure relief valve 8 exceeds the set value, the gas will automatically leak from the pressure relief port of the pressure relief valve 8 (the pressure relief of the second air bag 23 can also be performed by the medical staff pressing the start-stop button on the first PLC controller according to the judgment), at this time, the medical staff stops pressing the first air bag 10 and performs the next operation, thereby avoiding skin compression injury caused by overpressure, especially for elderly patients, patients with fragile skin after surgery, or patients with poor blood circulation, thereby improving the overall applicability of the equipment.
[0048] As Figure 8 and Figure 9The cleaning mechanism is located on the outer wall of the annular frame 1 and is used for cleaning the lower limbs of the patient. The cleaning mechanism comprises two first fixed seats 19 fixedly connected to the outer wall of the fixed plate 2 through a second bolt assembly. The inner side of the first fixed seat 19 is rotationally connected with a winding roller 20 through a first rotating shaft. The outer wall of the fixed plate 2 is fixedly connected with two second fixed seats 21 through a third bolt assembly. The inner side of the second fixed seat 21 is rotationally connected with an unwinding roller 22 through a second rotating shaft. One side of the first fixed seat 19 and the second fixed seat 21 is provided with a driving component for driving the winding roller 20 and the unwinding roller 22 to rotate synchronously. The driving component comprises synchronous wheels 33 fixedly connected to one end of the first rotating shaft and the second rotating shaft, respectively. The outer wall of the two synchronous wheels 33 is provided with a synchronous belt 32. The driving component further comprises an auxiliary fixed plate 35 fixedly connected to one side of the first fixed seat 19. The auxiliary fixed plate 35 is fixedly connected with a servo motor 31 on one side. The execution end of the servo motor 31 penetrates through the synchronous wheel 33 and is fixedly connected with the first rotating shaft. The inner side of the annular frame 1 is provided with a through slot. The two ends of the wiping cloth 5 are mounted on the outer wall of the winding roller 20 and the unwinding roller 22 through the through slot. The inner side of the through slot is rotationally connected with two groups of auxiliary rollers 30. The two groups of auxiliary rollers 30 are arranged between the wiping cloth 5 and the through slot, respectively.
[0049] A second PLC controller for controlling the start and stop of the servo motor 31 is arranged on the handle 12. A plurality of start and stop buttons of different rotating speed gears are arranged on the second PLC controller.
[0050] When the wiping cloth 5 is attached to the skin of the lower limbs of the patient, the staff can press the start and stop button on the second PLC controller to adjust the rotating speed of the servo motor 31 according to the needs. When the servo motor 31 is started, the first rotating shaft is driven to rotate the synchronous wheel 33 at the bottom of the first fixed seat 19 counterclockwise, and the winding roller 20 is driven to rotate counterclockwise to perform unwinding work on the wiping cloth 5. At this time, the synchronous belt 32 drives the synchronous wheel 33 to rotate and drives the unwinding roller 22 to rotate counterclockwise to wind the wiping cloth 5, so that the wet wiping cloth 5 rotates on the skin of the patient to clean the lower limbs of the patient. When cleaning, the medical staff can move up and down on the skin to clean multiple parts, so that the medical staff can complete the cleaning of the lower limbs of the patient in all directions by only controlling the rotating speed and moving the equipment up and down through the button, avoiding the difference in cleaning effect caused by manual wiping, and greatly improving the work efficiency of the medical staff.
[0051] When the thigh moves to the position of the calf, the wiping cloth 5 cannot completely attach to the skin due to the different circumferences of the legs. At this time, the staff only needs to press the first air bag 10 again to reattach the wiping cloth 5 to the skin, and then the cleaning can continue, thereby improving the practicability of the equipment.
[0052] When the device is used, the medical staff can press the button on the first PLC controller to manually open the pressure relief port of the pressure relief valve 8, at this time the gas in the second air bag 23 is discharged from the pressure relief port of the pressure relief valve 8, at this time the first clamping roller 25 and the second clamping roller 26 are driven to return to the original position under the action of the second spring 34 and the first spring 28, so that the wiping cloth 5 returns to the original state, and when it is necessary to clean and replace the wiping cloth 5, only the first, second and third bolt assemblies need to be disassembled, at this time the fixed plate 2, the first fixed seat 19 and the second fixed seat 21 are released from the limiting, and the rocker 14 is reversely rotated to release the limiting of the first clamping roller 25 and the second clamping roller 26 on the wiping cloth 5, so that the wiping cloth 5 can be cleaned and replaced, thereby improving the overall practicability of the device.
[0053] The working process of the technical scheme provided by the application is as follows:
[0054] The water inlet channel 3 is connected with a water pump through a communication hose, and the water pump pumps clean water into the water inlet channel 3 and flows out through the first fixed pipeline 4, so as to wet the wiping cloth 5;
[0055] The moving path of the first clamping roller 25 finally abuts against the second clamping roller 26, and the outer walls of the first clamping roller 25 and the second clamping roller 26 are provided with anti-skid pads;
[0056] The outer wall of the handle 12 is provided with a first PLC controller for controlling the start and stop of the pressure relief valve 8, and the first PLC controller is provided with a start and stop button;
[0057] First, the medical staff rotates the rocker 14 by hand to drive the lead screw 16 to rotate on the outer wall of the annular frame 1, so that the connecting plate 13 drives the two groups of first limiting slide rods 15 on the inner side to move towards the inner side of the annular frame 1, and the first clamping rollers 25 on the inner sides of the two arc-shaped connecting frames 18 are driven to move towards the center of the annular frame 1 through the two groups of first limiting slide rods 15, when the lead screw 16 is twisted to the maximum limit, the first clamping roller 25 and the second clamping roller 26 are butted, and the edges of the wiping cloth 5 are clamped in the middle, and the remaining lead screws 16 are repeatedly operated, so as to limit the edges of the wiping cloth 5, avoid displacement and wrinkles caused by self-weight sagging, water impact or wiping friction after wetting by water, and lay a foundation for subsequent work, thereby improving the overall practicability of the device;
[0058] Then the medical staff holds the handle 12, lifts the lower limbs of the patient towards the face, puts the feet into the fixed plate 2, and simply fixes the lower limbs of the patient, so that the lower limbs form an obtuse angle with the upper body, moves the fixed plate 2 to the thigh position, and then the medical staff repeatedly presses the first air bag 10, air is sucked into the second one-way valve 11, and then enters the second air bag 23 from the first one-way valve 9 through the second fixed pipeline 7, so that the second air bag 23 expands. The part of the second air bag 23 expands pushes the inner side of the wiping cloth 5 from the outer wall of the wiping cloth 5 to the patient's thigh skin direction, so that the wiping cloth 5 can be attached to the skin of the patient's lower limbs. The second air bag 23 generates a flexible pushing force by inflation and expansion, and exerts force from the outer wall of the wiping cloth 5 to the inner side of the patient's skin. By utilizing the elastic deformation characteristics of the air bag, the wiping cloth 5 can fully cover the skin surface by adapting to the curved profile of the patient's lower limbs, such as muscle lines, limb thickness differences, eliminating the problem of "partial suspension and poor adhesion" in traditional manual wiping, ensuring that there is no gap between the wiping cloth 5 and the skin, thereby improving the wiping effect and the work efficiency of the medical staff;
[0059] In the process of pushing the wiping cloth 5 to adhere to the skin of the patient's lower limbs by the second air bag 23, the two side edges of the wiping cloth 5 will shrink towards the center. Since the first clamping roller 25 and the second clamping roller 26 clamp the two sides of the wiping cloth 5, the two side edges of the wiping cloth 5 relatively move to the inside of the first clamping roller 25 and the second clamping roller 26 of the multiple sets of arc-shaped connecting frames 18 at this time, and continue to limit the two side edges of the wiping cloth 5. The relative movement of the clamping rollers does not require manual intervention and can automatically adapt to different shrinkage amplitudes, so that the limiting function is synchronized with the adhesion process. The medical staff does not need to adjust the wiping cloth 5 in the middle, significantly improving the continuity of the operation and the convenience of the operation, thereby improving the work efficiency of the medical staff;
[0060] When the wiping cloth 5 is adhered to the skin of the patient's lower limbs, the medical staff presses the first air bag 10 again. Since the patient's lower limbs block the second air bag 23 from expanding, the gas in the second air bag 23 continues to increase the pressure. When the pressure value of the air inlet of the pressure relief valve 8 exceeds the set value, the gas will automatically leak out of the pressure relief port of the pressure relief valve 8 (the second air bag 23 can also be relieved by the medical staff pressing the start-stop button on the first PLC controller), at this time, the medical staff stops pressing the first air bag 10 and performs the next operation, thereby avoiding skin compression injury caused by overpressure, especially for elderly patients, postoperative fragile skin or patients with poor blood circulation, thereby improving the overall applicability of the equipment;
[0061] The handle 12 is provided with a second PLC controller for controlling the start and stop of the servo motor 31. The second PLC controller is provided with multiple start-stop buttons of different rotating speeds;
