[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-5 , an auxiliary device for cleaning wounds of orthopedic patients, comprising a bed 1, a backrest 2 is fixedly connected to one end of the top of the bed 1, a tailboard 3 is fixedly connected to the other end of the top of the bed 1, and the same joint stabilization assembly 29 is installed on the outer wall of the backrest 2 and the tailboard 3. The joint stabilization assembly 29 can limit the position of the patient's arms and legs after lying on the bed 1 to avoid shaking. A nursing port 4 is opened in the middle of the bed board 1 of the bed 1, and the nursing port 4 is opened in the middle of the bed board 1. When a fracture occurs and the patient lies on the bed board 1, the nursing port 4 can generally be located below the patient's waist.

[0041] A driving chamber 8 is fixedly connected to the bottom of the inner wall of the bed body 1, and a first driving device 9 is arranged inside the driving chamber 8. The output end of the first driving device 9 is fixedly connected to a driving shaft 10, and the output end of the driving shaft 10 is fixedly connected to a power steering gear 11. The output end of the power steering gear 11 is connected to a rotary column 22 arranged below the nursing port 4. A sleeve column 23 is sleeved on the surface of the rotary column 22, and an arc-shaped slideway 203 is provided on the surface of the sleeve column 23. The arc-shaped slideway 203 extends in an arc shape from the upper end of one side of the front of the sleeve column 23 to the lower end of the other side, and then continuously extends in an arc shape along the lower end of one side of the back to the upper end of the other side, forming a closed loop circulation. The surface of the sleeve column 23 is slidably connected to a sliding rod 24 along the arc-shaped slideway 203, and the end of the sliding rod 24 away from the sleeve column 23 is fixedly connected to a massage stick 25. The arc slide 203 is a trapezoidal structure with a relatively small opening end and a relatively large internal space. A spherical block protrudes from one end of the sliding rod 24, and the spherical block is inserted into the arc slide 203. Since the size of the spherical block is larger than the size of the opening end of the arc slide 203, the sliding rod 24 will not slide out of the arc slide 203. The size of the sliding rod 24 itself is smaller than the size of the opening end of the arc slide 203, so it can slide in the arc slide 203. Under the drive of the first drive device 9, the driving shaft 10 is driven to move, and the driving shaft 10 drives the driving steering device 11. When the rotating column 22 rotates, it will drive the rotation of the sleeve column 23. In conjunction with the arc slide 203, the sliding rod 24 can slide more smoothly on the surface of the sleeve column 23. When the sliding rod 24 slides on the arc slide 203 opened on the surface of the sleeve column 23, the massage stick 25 will rotate accordingly, and a large range of massage rehabilitation will be performed on the patient's waist.

[0042] See also Figure 2The top of the inner wall of the bed body 1 is fixedly connected to a limiting slide 12, and blocking plates are fixed at both ends of the limiting slide 12. A sliding area is formed on the limiting slide 12 between the two blocking plates, and a baffle 13 is laterally fixed to the middle part of the limiting slide 12. The baffles 13 respectively form sliding areas with the two blocking plates. The baffles 13 are located in the middle of the position, so the space of the sliding areas on both sides is the same. The top surface of the limiting slide 12 is located in the two sliding areas and is slidably connected to two lower sliding blocks 14 respectively, which can slide back and forth in the sliding area through the lower sliding blocks 14. A telescopic driving rod 15 is fixedly connected to the right side of one of the lower sliding blocks 14, and the telescopic driving rod 15 is connected to the first driving device 9, and the first driving device 9 drives the telescopic driving rod 15 to drive the lower sliding block 14 to reciprocate in the sliding area.

[0043] Each lower sliding block 14 is movably connected to a lifting adjustment rod 16 on one side close to the baffle 13. The two lifting adjustment rods 16 are cross-arranged and hingedly connected in the middle of the two lifting adjustment rods 16. A hinge shaft 1601 is provided in the middle. An upper sliding block 17 is movably connected to the top of the lifting adjustment rod 16. The inner sides of the two upper sliding blocks 17 are respectively fixedly connected to the two ends of the positioning spring 18. The tops of the two upper sliding blocks 17 are slidably connected to a support plate 19. The support plate 19 is arranged parallel to the limit slide 12. The upper sliding block 17 is slidably connected along the support plate 19. When the first driving device 9 drives one of the lower sliding blocks 14 to reciprocate in the sliding area, a lifting adjustment rod 16 corresponding to this lower sliding block 14 will gradually tilt or stand upright. When the telescopic driving rod 15 is telescopic, the lower sliding block 14 can slide on the surface of the limit slide 12, and cooperate with the sliding of the positioning spring 18 and the upper sliding block 17 to achieve the effect of stretching or compressing the lifting adjustment rod 16 as a whole. Driven by the hinge shaft 1601 and the positioning spring 18, the other lifting adjustment rod 16 will be driven to move synchronously, so that the support plate 19 will rise or fall.

[0044] The top of the support plate 19 is fixedly connected with a bracket 20, which is the general frame of the entire massage mechanism and plays a role of stable support during the massage rehabilitation process of the patient. When the support plate 19 rises or falls, it will drive the bracket 20 to move synchronously, so that the bracket 20 will pass through the nursing port 4 or retract back. When passing through the nursing port, it can contact the patient's waist, and can push up or fall back the waist to achieve a certain massage. Strip holes are provided on both sides of the bracket 20, and a cover plate 21 is fixedly connected to the top of the bracket 20. A rotation groove is provided in the middle of the bottom surface of the cover plate 21. The rotary column 22 is movably inserted into the rotation groove and can rotate along the rotation groove, which is equivalent to the rotary column 22 being sleeved in the entire bracket 20 and limited by the rotation groove of the cover plate 21. When the rotary column 22 is driven to rotate by the first driving device 9, the driving shaft 10 and the power steering gear 11, the arc slide 203 rotates synchronously, driving the massage rod 25 to rotate synchronously. Because the massage rod 25 is arranged on both sides of the bracket 20, it can massage both sides of the patient's waist.

[0045] See also Figure 1 and Figure 3 A buffer plate 26 is fixedly connected to one side of the tail plate 3 facing the bed body 1, and a surround 206 is fixed on both sides of the buffer plate 26. One end of the surround 206 is fixed on the tail plate 3, and a buffer compression spring 27 is fixedly connected to the outer side of the buffer plate 26. A massage plate 28 is fixedly connected to the outer side of the buffer compression spring 27. Both ends of the massage plate 28 are slidably connected to the surround 206. A number of massage balls are evenly arranged on the outer side of the massage plate 28. The buffer plate 26 is connected to the second driving device, and the second driving device drives the buffer plate 26 to vibrate. At the same time, the patient's feet stepping on the massage balls can achieve a certain reciprocating massage under the action of the buffer compression spring 27. The buffer plate 26 cooperates with the buffer compression spring 27 to enable the massage plate 28 to massage the soles of the patient's feet, thereby achieving the effect of assisting rehabilitation of the patient's body.

[0046] A control room 5 is fixedly connected to the bottom of the inner wall of the bed body 1, and a first controller 6 is arranged inside the control room 5. The first drive device 9 and the second drive device are electrically connected to the first controller 6 respectively. The first controller 6 is used to control the movement of the first drive device 9 and / or the second drive device, control the movement of the first drive device and / or the second drive device, realize intelligent control and monitoring, and reduce manual operation costs.

[0047] See also Figure 6-9The same joint stabilizing assembly 29 is installed on the outer wall of the backrest 2 and the tail plate 3. The joint stabilizing assembly 29 includes: a mounting bracket 30, the mounting bracket 30 is embedded in the backrest 2 and the tail plate 3, a through hole 31 is opened on the mounting bracket 30, a through slot 32 is provided in the mounting bracket 30, a movable kit 34 is movably arranged in the through slot 32, two groups of positioning columns 35 are symmetrically fixed on the outer wall of the movable kit 34, and the positioning columns 35 are movably arranged in the through hole 31, and the threaded connecting rod 36 is connected to the movable kit 34 by threads. The mounting adjustment plate 33 is mounted on the outer wall of the threaded connecting rod 36 through a threaded sleeve 37. Specifically, a threaded sleeve 37 is fixed on one side of the mounting adjustment plate 33, and the threaded sleeve 37 can be fixedly connected to one side of the mounting adjustment plate 33 by welding or other fixing methods, and a threaded connecting rod 36 is movably penetrated in the threaded sleeve 37.

[0048] Furthermore, a slide groove 38 is provided on the other side of the mounting adjustment plate 33, and two groups of annular fixing units 39 are movably provided in the slide groove 38. The annular fixing units 39 and the threaded sleeves 37 are respectively located on the two sides of the mounting adjustment plate 33 without affecting each other. Figure 1 The structure of the annular fixing unit 39 is omitted in the figure, which is a schematic diagram.

[0049] Further, the annular fixing unit 39 includes: an arc-shaped fixing member 41, avoidance grooves 55 are provided at both ends of the arc-shaped fixing member 41, a guide groove 42 is opened on the arc-shaped fixing member 41, an arc-shaped plate 1 40 and an arc-shaped plate 2 44 are respectively movably arranged in the avoidance grooves 55 at both ends of the arc-shaped fixing member 41, and one end of the arc-shaped plate 1 40 and the arc-shaped plate 2 44 arranged in the avoidance groove 55 are respectively fixed with a guide limit column 2 49 and a guide limit column 1 43, and the guide limit column 2 49 and the guide limit column 1 43 are movably arranged in the guide groove 42 and can adjust their positions along the guide groove 42, and the end of the arc-shaped plate 1 40 away from the avoidance groove 55 extends to form an insertion rod 47, An arc groove 46 is formed at one end of the arc plate 2 44 away from the avoidance groove 55, and the central box body 45 is fixedly connected to the arc plate 2 44, and a plurality of groups of buffer air cushions 48 are formed on the inner circles of the arc plate 1 40 and the arc plate 2 44, and a ratchet 50 is formed on the side of the insertion rod 47 close to the central box body 45, a rectangular movable bracket 51 is movably arranged in the central box body 45, a driving motor 52 is fixedly arranged in the central box body 45, a cam 53 is fixedly sleeved on the output shaft of the driving motor 52, and the cam 53 is movably arranged on the rectangular movable bracket 51, and the rectangular movable bracket 51 extends on the side close to the insertion rod 47 to form a bevel tooth 54 that matches the ratchet 50.

[0050] Working principle and beneficial effects: When in use, by twisting the threaded connecting rod 36, since the threaded connecting rod 36 is threadedly connected to the movable kit 34, the threaded connecting rod 36 will extend and contract along the movable kit 34, thereby adjusting the distance between the installation adjustment plate 33 and the bed body 1, and then the installation adjustment plate 33 can be toggled so that the installation adjustment plate 33 can rotate in the horizontal direction with the through hole 31 as the rotation point through the movable kit 34 under the restriction of the positioning column 35, thereby adjusting the angle between the installation adjustment plate 33 and the bed body 1, and since the threaded connecting rod 36 is extended and contracted, the installation adjustment plate 33 is driven to rotate as a whole. At this time, the installation adjustment plate 33 can be rotated around the threaded connecting rod 36 by rotating the threaded sleeve 37, so that the angle of the installation adjustment plate 33 along the Z-axis direction can be fine-tuned to keep it horizontal. After adjusting the installation adjustment plate 33 to a comfortable posture for the patient in the above manner, the two sets of annular fixing units 39 are toggled to move along the slide groove 38, thereby adapting to patients of different body shapes. Subsequently, after the patient's arm or thigh is placed in the arc-shaped fixing member 41, the guide limit column 1 43 and the guide limit column 2 49 are moved to slide along the guide groove 42, so that the arc plate 1 40 and the arc plate 2 44 move towards each other until several groups of buffer air cushions 48 are in contact with the patient's arm or thigh. The drive motor 52 is started to drive the cam 53 to rotate, and the cam 53 will push the rectangular movable bracket 51 to slide along the inner wall of the central box body 45 until the oblique teeth 54 match the ratchet teeth 50, completing the locking between the arc plate 1 40 and the arc plate 2 44, thereby fixing the patient's arm or thigh to prevent the patient from moving around during the treatment process and causing treatment failure.

[0051] Furthermore, it also includes: a counter, which is arranged on the upper sliding block 17 and is used to detect the number of times the upper sliding block 17 moves;

[0052] A displacement sensor, disposed on the upper sliding block 17, for detecting the maximum displacement of the upper sliding block 17;

[0053] An alarm device 7, fixedly arranged on the top of the control room 5, for monitoring the critical failure point of the positioning spring 18;

[0054] A second controller, which is arranged in the control room 5 and is electrically connected to the counter, the displacement sensor and the alarm device 7 respectively;

[0055] The second controller controls the alarm device 7 to work based on the counter and the displacement sensor, including the following steps:

[0056] Step 1: Based on the detection values ​​of the counter and the displacement sensor, the failure critical point of the positioning spring 18 is calculated by formula (1):

[0057]

[0058] Wherein, X is the critical failure point of the positioning spring 18, N1 is the detection value of the counter, L1 is the maximum displacement detected by the displacement sensor, L2 is the minimum displacement detected by the displacement sensor, L3 is the natural length of the positioning spring 18, R1 is the outer diameter of the positioning spring 18, R2 is the inner diameter of the positioning spring 18, S is the cross-sectional area of ​​the positioning spring 18, N2 is the number of spiral turns of the positioning spring 18, h is the spiral moment of the positioning spring 18, E1 is the elastic modulus of the positioning spring 18, C is the Poisson's ratio of the material of the positioning spring 18, and E2 is the tensile strength of the positioning spring 18;

[0059] Step 2: The second controller compares the critical failure point of the positioning spring 18 with the preset critical failure point of the positioning spring 18. When the critical failure point of the positioning spring 18 is not within the preset critical failure point range of the positioning spring 18, the second controller controls the alarm device 7 to issue an alarm prompt.

[0060] Working principle and beneficial effects: When the present invention is used for a long time, the lifting and adjusting rod 16 drives the two groups of upper sliding blocks 17 to drive the support plate 19 to rise and fall. The positioning spring 18 will fail due to repeated stretching and compression, and cannot play a role of buffering and supporting the two groups of upper sliding blocks 17 and the lifting and adjusting rod 16, which may cause the patient to be bumped during treatment. Therefore, a counter and a displacement sensor are used to detect the displacement distance of the two groups of upper sliding blocks 17 and the number of times the positioning spring 18 is stretched and stretched. The second controller uses formula (1) to calculate the critical failure point of the positioning spring 18. When the critical failure point of the positioning spring 18 is not within the preset critical failure point range of the positioning spring 18 (0.85-1.0), the second controller controls the alarm device 7 to issue an alarm prompt to remind the operator to detect the strength of the positioning spring 18 to prevent the positioning spring 18 from breaking or being damaged, thereby improving the safety and reliability of the device.

[0061] Working principle and beneficial effects: The general working principle and operation process of the orthopedic patient wound cleaning auxiliary equipment are as follows: first, when the patient is not using the physiotherapy bed for rehabilitation, the patient can use it as an ordinary bed and rest on the backrest 2. When rehabilitation is needed, the first drive device 9 can be started to move the telescopic drive rod 15 inward, thereby moving the lower sliding block 14 inward, and the linkage lifting and adjusting rods 16 are close to each other. Under the action of the positioning spring 18, the upper sliding block 17 slides on the top of the support plate 19. At this time, the lifting and adjusting rod 16 is pulled up as a whole, so as to avoid moving the patient when cleaning the patient's wound. By adjusting the equipment, it is convenient to clean the patient's wound, so the support plate 19 moves up, and the cover plate 21 will gradually rise until it passes through the nursing port 4.
