Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an adjustable nursing support device for children after surgery. Background Technology
[0002] The elbow joint is composed of the distal end of the humerus and the proximal articular surfaces of the radius and ulna, which are enclosed in a joint capsule. During the rehabilitation treatment after elbow fracture surgery, auxiliary fixation devices are needed to fix and limit the elbow joint, restrict the patient's elbow joint movement, and avoid affecting the rehabilitation of the elbow joint.
[0003] For children, it is even more uncontrollable. Existing technologies use children's elbow restraint and fixation devices to fix the elbow, but after fixation, the arm is kept in a straight position and the angle cannot be adjusted. Although the patent with authorized publication number CN114732586B discloses an orthopedic elbow joint fracture postoperative rehabilitation device, which allows the elbow to move within a small range to help muscle recovery when the recovery reaches a certain level, it does not limit the relative position of the ulna and radius in the child's forearm. The ends of the ulna and radius closer to the palm can still rotate, and rotation will affect the postoperative recovery of the elbow joint. Moreover, after the elbow joint is fixed, the elbow joint flexion point is still exposed, and there is a risk of bumping or hitting this point when the child is playing. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the existing technology and provide an adjustable nursing support device for children after surgery. It can firmly clamp and fix the child's elbow joint. As the child recovers after surgery, the relative angle between the upper arm and forearm can be adjusted at any time. In the early postoperative period, it can limit the relative position of the ulna and radius in the forearm, preventing the child from uncontrollably rotating the end of the forearm and affecting the postoperative recovery of the elbow joint. The elbow protection mechanism can prevent the elbow joint flexion point from being bumped or knocked. It can also be removed to change dressings or perform physical therapy at the elbow joint flexion point. It can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable nursing support device for postoperative care in children, comprising an upper and lower arm support and clamping mechanism, wherein the upper and lower arm support and clamping mechanism includes a forearm support plate, a first support plate, an adjusting shaft, a second support plate, an arc support plate, an upper arm restraint plate, and an upper arm restraint assembly. The forearm support plate is an arc plate. Two first support plates are respectively provided on the front and rear sides of the left end of the forearm support plate. The two first support plates are respectively fixedly connected to one end of two longitudinal adjusting shafts on the sides of the two support plates that are far apart from each other. Two second support plates are respectively provided on the front and rear sides of the bottom of the arc support plate. The two second support plates are respectively rotatably connected to the corresponding adjusting shafts. The top of the arc support plate is fixedly connected to the bottom of the upper arm restraint plate. An upper arm restraint assembly is provided on the outer side of the upper arm restraint plate.
[0006] Also includes:
[0007] The boom and arm angle adjustment mechanism is installed on the outside of support plate two;
[0008] The radius and ulna position limiting mechanism is installed on the inner side of the forearm support plate, and the radius and ulna clamping mechanism is installed on the inner side of the radius and ulna position limiting mechanism.
[0009] The upper arm restraint plate is secured to the upper arm via an upper arm restraint assembly, and it rests against the back of the upper arm. The forearm support plate supports the bottom of the forearm near the elbow flexion point. The upper arm restraint plate and forearm support plate are connected by support plate one, support plate two, and an adjusting shaft. The adjusting shaft corresponds to both sides of the elbow flexion point, thus maintaining a stable position of the elbow flexion point when the upper arm restraint plate and forearm support plate move relative to each other. After adjusting the angle of the upper arm restraint plate and forearm support plate, the upper and lower arm angle adjustment mechanism is used to maintain its angle stability. Due to the existence of the upper and lower arm angle adjustment mechanism, the angle of the upper arm and forearm can be continuously adjusted as needed during subsequent rehabilitation. The radius and ulna position limiting mechanism can extend and retract relative to the forearm support plate to accommodate different children's arm lengths. The radius and ulna clamping mechanism aligns with the ends of the ulna and radius closest to the palm. This clamping mechanism secures and fixes these ends. The radius and ulna position limiting mechanism can rotate a certain angle relative to the forearm support plate before fixing, thus allowing the radius and ulna clamping mechanism to rotate and fix. This allows the ends of the ulna and radius closest to the palm to rotate and be fixed, maintaining a specific relative position. For example, the ends of the ulna and radius closest to the palm can be in a vertically or anteriorly aligned position. This stabilizes the elbow joint and prevents the elbow joint from being pulled by movement of the distal ends of the ulna and radius, even though the elbow joint is fixed. This addresses common postoperative support issues in children's elbow joints.
[0010] Furthermore, the arm and boom angle adjustment mechanism includes an adjustment disc and an elastic locking control component. The end of the adjustment shaft away from the support plate is fixedly connected to the adjustment disc. Multiple adjustment slots are arranged in a ring array on the outer periphery of the adjustment disc. A sliding sleeve is provided on the outer side of the support plate. A locking slide rod is slidably connected inside the sliding sleeve. A locking head is fixedly connected to the bottom end of the locking slide rod. The locking head engages with the corresponding adjustment slot. The locking slide rod is connected to the sliding sleeve through the elastic locking control component. Since the adjusting shaft and the corresponding support plate are fixedly connected, when support plate one and support plate two move relative to each other, the adjusting disc will move with the adjusting shaft and support plate one. With the help of the elastic locking control component, the locking head is disengaged from the corresponding adjusting slot. At this time, the relative angle of support plate one and support plate two can be freely adjusted, that is, the angle of the upper arm restraint plate and the forearm support plate can be freely adjusted. When the angle of the patient's upper arm and forearm is appropriate, the locking head is engaged with the corresponding adjusting slot on the adjusting disc by the elastic locking control component, and the relative angle of support plate one and support plate two moves accordingly. At this time, the angle of the upper arm restraint plate and the forearm support plate is moved accordingly, thus completing the locking of the angle of the patient's upper arm and forearm. During the postoperative recovery process, the relative angle of the upper arm and forearm can be adjusted as needed.
[0011] Furthermore, the radius and ulna position limiting mechanism includes a forearm end support plate. The forearm support plate has two transverse through grooves on its front and rear sides, and multiple arc-shaped sliding grooves are equally spaced on the upper and lower sides of each transverse through groove. Positioning grooves are equally spaced on the left side of each arc-shaped sliding groove. The forearm support plate is provided inside the forearm support plate. An anti-agglomeration guide surface is provided on the inner side of the left end of the forearm end support plate. The anti-agglomeration guide surface is used to prevent the left edge of the forearm end support plate from aggravating the bottom of the forearm. Two limiting sliders are provided on the front and rear sides of the forearm end support plate, and the two limiting sliders extend into the corresponding two transverse through grooves. The end of the limiting slider away from the forearm end support plate is threaded with a locking bolt. The hexagonal head of the locking bolt presses against the outer side of the forearm support plate. Loosen the locking bolt so that the hexagonal head of the locking bolt is away from the outside of the forearm support plate. The limiting slider can slide laterally along the corresponding transverse groove, allowing the forearm end support plate to move left and right relative to the forearm support plate. The forearm end support plate needs to be slid to the right end corresponding to the position of the patient's forearm near the palm, that is, the radius and ulna clamping mechanism corresponds to the end of the ulna and radius near the palm. Then, let the radius and ulna clamping mechanism initially limit the end of the ulna and radius near the palm. When the radius and ulna clamping mechanism limits the end of the ulna and radius near the palm, the ulna and radius are in a state of vertically corresponding distribution. At this time, the forearm can still move left and right relative to the radius and ulna clamping mechanism for adjustment. When it is necessary to adjust the distribution state of the end of the ulna and radius near the palm, rotate the forearm end support plate relative to the forearm support plate. First, ensure that the limiting slider corresponds to the arc groove. In order to make the limiting slider correspond to the arc groove, the forearm end support plate may need to be rotated halfway. The support plate slides a short distance to the left and right relative to the forearm support plate. This distance will not affect the limiting effect of the radius and ulna clamping mechanism on the end of the ulna and radius near the palm. After the forearm end support plate is rotated to a suitable angle relative to the forearm support plate, the forearm end support plate is moved to the left relative to the forearm support plate, allowing the limiting slider to extend into the corresponding positioning groove. Then, the locking bolt is tightened, allowing the hexagonal head of the locking bolt to press against the outer side of the forearm support plate, completing the fixation of the forearm end support plate relative to the forearm support plate after adjustment. At this time, the limiting slider can no longer move along the arc groove. The radius and ulna clamping mechanism further clamps and fixes the end of the ulna and radius near the palm, thus completing the limiting and fixation of the distribution state of the ulna and radius. This prevents uncontrolled child movement from changing the state of the ulna and radius and affecting the recovery of the elbow joint. As the elbow joint recovers, the clamping force of the radius and ulna clamping mechanism on the ulna and radius can be relaxed.
[0012] Furthermore, the radius and ulna clamping mechanism includes a radius and ulna splint. Two strip grooves are respectively opened on the front and back sides of the bottom of the forearm end support plate. The two strip grooves are movably connected to the bottom ends of the two radius and ulna splints through two movable shafts. The tops of the two radius and ulna splints are respectively bent relative to each other. Two nuts are respectively embedded and installed on the front and back sides of the right end of the forearm end support plate. Each nut is threaded with two clamping bolts. The end of each clamping bolt abuts against the side of the corresponding radius and ulna splint. Two radius and ulna splints are used to clamp the sides of the ulna and radius. Twisting the first clamping bolt allows it to move relative to the first nut, causing it to press against the corresponding radius and ulna splint. This brings the two splints closer together, clamping and fixing the sides of the ulna and radius. When the two splints clamp the ulna and radius, they are aligned vertically. Rotating the forearm end support plate will also cause the ends of the ulna and radius near the palm to rotate around the center of the forearm, thus changing the distribution of the ulna and radius and allowing the muscles at the elbow joint to recover properly. Since the clamping bolt provides a rigid clamping effect on the two radius and ulna splints, the splints will fit tightly against the patient's forearm. Therefore, breathable gauze can be wrapped around the forearm or a breathable pad can be placed on the inside of the splints.
[0013] Furthermore, the radius and ulna clamping mechanism also includes a forearm tightening band. An inner arc groove is provided on the front side of the forearm end support plate, and one end of the forearm tightening band is connected in the inner arc groove. The other end of the forearm tightening band is connected to a second male Velcro fastener. An outer arc groove is provided on the rear side of the forearm end support plate, and a second female Velcro fastener is provided in the outer arc groove. A second notch is provided on the top rear side of the forearm end support plate corresponding to the position of the outer arc groove. A first notch is provided on the top of the radius and ulna clamping plate corresponding to the position of the inner arc groove. When the ulna and radius do not need to be fixed, for comfort, the radius and ulna splint is no longer tightly attached to both sides of the patient's forearm. At this time, the forearm can move within the forearm end support plate. However, the forearm is prone to detaching from the forearm end support plate and the forearm support plate. Therefore, a forearm tightening strap is provided. The forearm tightening strap is tightened on the upper side of the forearm by using the adhesion of the male side two and the female side two of the Velcro. The inner arc groove is designed to facilitate the connection of the forearm tightening strap. The outer arc groove is designed to avoid affecting the retraction of the radius and ulna splint into the forearm support plate. The notch one and notch two are designed to avoid affecting the restraining effect of the forearm tightening strap on the upper side of the forearm, allowing the forearm tightening strap to fit tightly against the upper side of the forearm.
[0014] Furthermore, it also includes a pressure massage component, which includes an airbag. An airbag is positioned between the radius and ulna splint and the forearm end support plate. The airbag has evenly distributed airbag protrusions on the side near the radius and ulna splint, and each airbag protrusion is provided with massage adhesive dots. The radius and ulna splint has through holes corresponding to the airbag protrusions, and the airbag protrusions extend into the corresponding through holes. An inflation / deflation port is provided on the side of the airbag, and an air valve is installed on the inflation / deflation port. Open valve one and inflate / deflate the airbags using the inflation / deflation ports. When the airbags inflate, their expansion applies pressure to the forearm using the radius and ulna splint. The bulges on the airbags also expand, allowing the bulges to apply a point massage to the forearm through the holes in the radius and ulna splint using the massage dots. When the airbags deflate, they relax. This alternation of compression and relaxation completes the massage of the forearm, promoting blood circulation and relieving the discomfort caused by the pressure of the radius and ulna splint on the forearm.
[0015] Furthermore, the system also includes a functional implementation module, which comprises a detachable base box, an inflation component, and a power supply component. The detachable base box is detachably installed at the bottom of the forearm support plate, and the inflation component and power supply component are installed inside the detachable base box. Since arm massage is neither necessary nor a regular occurrence, the inflation component and power supply component do not need to be constantly installed at the bottom of the forearm support plate. When massage is required, the detachable base box is installed, allowing the inflation component and power supply component to work together to achieve the massage function. During massage, the patient does not need to remain in one place; when not in use, the detachable base box can be removed, reducing the burden and improving comfort, making it suitable for postoperative rehabilitation care of pediatric patients.
[0016] Furthermore, it also includes a large arm clamping and pressing mechanism, which comprises hinges, large arm clamping plates, arc-shaped convex plates, retaining grooves, and large arm clamping plate clamping control components. The front and rear sides of the large arm restraint plate are respectively connected to two large arm clamping plates via hinges. The bottom ends of the two large arm clamping plates are integrally formed and connected to the top ends of two arc-shaped convex plates. Two retaining grooves are respectively provided on the inner sides of the front and rear ends of the arc-shaped support plate, and the bottom ends of the two arc-shaped convex plates are respectively located within the two retaining grooves. Large arm clamping plate clamping control components are installed at the front and rear ends of the arc-shaped support plate. The retaining grooves on the arc-shaped support plate limit the arc-shaped convex plates, thereby limiting the maximum opening angle of the two large arm clamping plates. The large arm clamping plate clamping control components allow the two large arm clamping plates to be closer to the sides of the large arm, providing better clamping action and improving the restraint stability between the large arm restraint plate and the large arm, preventing the large arm restraint plate from affecting the support effect on the elbow joint relative to the movement of the large arm.
[0017] Furthermore, it also includes an elbow protection mechanism, which includes an elbow-side arc-shaped protective plate, an arc-shaped guide groove in the middle of the arc-shaped support plate, an elbow-side arc-shaped protective plate slidably connected in the arc-shaped guide groove, a control protrusion on the top of the elbow-side arc-shaped protective plate, and an adjusting screw threadedly connected to the middle of the outer side of the arc-shaped support plate, the adjusting screw abutting against the side of the elbow-side arc-shaped protective plate.
[0018] Furthermore, the elbow protection mechanism also includes a mounting plate, a curved frame, and an elbow bottom guard plate. Two mounting plates are respectively provided on the two support plates on opposite sides. The two mounting plates are respectively fixedly connected to the two curved frames by mounting bolts. The bottom ends of the two curved frames are respectively fixedly connected to the front and rear sides of the right end of the elbow bottom guard plate. An infrared therapy lamp slot is provided in the middle of the left end of the elbow bottom guard plate, and mounting holes are respectively provided in the elbow bottom guard plate at the front and rear sides of the infrared therapy lamp slot.
[0019] The elbow base plate and elbow side arc-shaped protective plate provide protection for the elbow joint flexion point, preventing bumps and knocks from children's movements. This provides more comprehensive protection for the elbow joint and is more suitable for children. The infrared therapy lamp slot and mounting holes allow for the installation of therapy equipment, such as an infrared therapy lamp, at the elbow base plate. Combined with the power supply component in the functional module, therapy can be administered during children's activities without restricting their movement, making it suitable for post-operative care. When using the infrared therapy lamp or for elbow examination and dressing changes, the adjusting screw can be loosened, and the elbow side arc-shaped protective plate can be pulled upwards by manipulating the raised edge to provide more installation space on the upper left side of the elbow base plate. At other times, the elbow side arc-shaped protective plate should be positioned close to the left side of the elbow base plate for comprehensive elbow protection.
[0020] Compared with existing technologies, the beneficial effects of this adjustable postoperative nursing support device for children are:
[0021] 1. This adjustable postoperative nursing support device for children consists of an upper arm restraint plate that is secured to the upper arm via an upper arm restraint assembly and rests against the back of the upper arm. A forearm support plate supports the bottom of the forearm near the elbow flexion point. The upper arm restraint plate and forearm support plate are connected by a support plate, a support plate, and an adjustment shaft. The adjustment shaft corresponds to both sides of the elbow flexion point, thus ensuring a stable position of the elbow flexion point during relative movement of the upper arm restraint plate and forearm support plate. After adjusting the angles of the upper arm restraint plate and forearm support plate, an upper and lower arm angle adjustment mechanism is used to maintain their angle stability. Due to the presence of this mechanism, the angles of the upper and lower arms can be continuously adjusted as needed during subsequent recovery.
[0022] 2. This adjustable postoperative nursing support device for children features a radius and ulna position limiting mechanism that can extend and retract relative to the forearm support plate to accommodate different children's arm lengths. This allows the radius and ulna clamping mechanism to correspond to the ends of the ulna and radius near the palm, clamping and fixing them. The radius and ulna position limiting mechanism can rotate a certain angle relative to the forearm support plate before fixing, thus allowing the radius and ulna clamping mechanism to rotate and fix. This allows the ends of the ulna and radius near the palm to maintain a specific relative position, such as being vertically or anteriorly aligned. This stabilizes the elbow joint and prevents the elbow joint from being pulled by movement of the ulnar and radial ends despite the elbow joint being fixed. This addresses common issues in postoperative nursing support for children's elbow joints.
[0023] 3. This adjustable postoperative nursing support device for children provides a secure clamping and fixation for the child's elbow joint. As the child recovers, the relative angle between the upper arm and forearm can be adjusted at any time. In the early postoperative period, it can limit the relative position of the ulna and radius in the forearm, preventing the child from uncontrollably rotating the end of the forearm and affecting the postoperative recovery of the elbow joint. The elbow protection mechanism can prevent the elbow joint flexion point from being bumped or knocked, and the protection can also be removed to change dressings or perform physical therapy at the elbow joint flexion point.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Example 1, please refer to Figures 1 to 9This embodiment provides a technical solution: an adjustable nursing support device for pediatric postoperative care, including an upper and lower arm support and clamping mechanism 1. The upper and lower arm support and clamping mechanism 1 includes a forearm support plate 11, a first support plate 12, an adjusting shaft 13, a second support plate 14, an arc support plate 15, an upper arm restraint plate 16, and an upper arm restraint assembly. The forearm support plate 11 is an arc plate. Two first support plates 12 are respectively provided on the front and rear sides of the left end of the forearm support plate 11. The two first support plates 12 are respectively fixedly connected to one end of two longitudinal adjusting shafts 13 on the side that is far apart from each other. Two second support plates 14 are respectively provided on the front and rear sides of the bottom of the arc support plate 15. The two second support plates 14 are respectively rotatably connected to the corresponding adjusting shafts 13. The top of the arc support plate 15 is fixedly connected to the bottom of the upper arm restraint plate 16. An upper arm restraint assembly is provided on the outer side of the upper arm restraint plate 16.
[0036] The upper arm restraint assembly includes a fixing seat 17, an upper arm restraint strap 18, a male hook and loop fastener 19, and a female hook and loop fastener 110. Two fixing seats 17 are provided on the outer middle of the upper arm restraint plate 16. Each fixing seat 17 is connected to the middle of the upper arm restraint strap 18. One end of the upper arm restraint strap 18 is provided with the male hook and loop fastener 19, and the other end of the upper arm restraint strap 18 is provided with the female hook and loop fastener 110. The two ends of the upper arm restraint strap 18 are glued together by the male hook and loop fastener 19 and the female hook and loop fastener 110, so that the upper arm restraint strap 18 restrains and fixes the upper arm restraint plate 16 to the upper arm.
[0037] It is also equipped with an upper and lower arm angle adjustment mechanism 2, a radius and ulna state limiting mechanism 3, and a radius and ulna clamping mechanism 4.
[0038] The boom and arm angle adjustment mechanism 2 is installed on the outside of the support plate 2 14.
[0039] The boom and arm angle adjustment mechanism 2 includes an adjustment disc 21, an adjustment slot 22, a sliding sleeve 23, a locking slide rod 24, a locking head 25, and an elastic locking control assembly. The adjustment disc 21 is fixedly connected to the end of the adjustment shaft 13 away from the support plate 12. Multiple adjustment slots 22 are arranged in a ring array on the outer periphery of the adjustment disc 21. A sliding sleeve 23 is provided on the outer side of the support plate 14. A locking slide rod 24 is slidably connected inside the sliding sleeve 23. A locking head 25 is fixedly connected to the bottom end of the locking slide rod 24. The locking head 25 engages with the corresponding adjustment slot 22. The locking slide rod 24 is connected to the sliding sleeve 23 through the elastic locking control assembly.
[0040] The elastic locking control assembly includes a compression spring 26 and a pull ring 27. A guide groove is provided on the outer side of the locking slide 24, and a guide block is provided on the inner side of the slide sleeve 23, which is slidably connected to the guide groove. The compression spring 26 is provided in the guide groove. One end of the compression spring 26 is connected to the locking head 25, and the other end of the compression spring 26 is connected to the guide block. The pull ring 27 is detachably installed on the top of the locking slide 24. The elastic force of the compression spring 26 pushes the locking slide 24 toward the control disc 21, so that the locking head 25 engages with the corresponding control slot 22. When it is necessary to adjust the state of the forearm support plate 11 and the upper arm restraint plate 16 by contacting the engagement state, the pull ring 27 is pulled to compress the compression spring 26, so that the locking head 25 disengages from the control slot 22.
[0041] Since the adjusting shaft 13 and the corresponding support plate 12 are fixedly connected, when the support plate 12 and the support plate 24 move relative to each other, the adjusting disc 21 will move with the adjusting shaft 13 and the support plate 12. With the help of the elastic locking control component, the locking head 25 is disengaged from the corresponding adjusting slot 22. At this time, the relative angle of the support plate 12 and the support plate 24 can be freely adjusted, that is, the angle of the upper arm restraint plate 16 and the forearm support plate 11 can be freely adjusted. When the angle of the patient's upper arm and forearm is appropriate, the locking head 25 is engaged with the corresponding adjusting slot 22 on the adjusting disc 21 by means of the elastic locking control component, and the relative angle of the support plate 12 and the support plate 24 moves accordingly. At this time, the angle of the upper arm restraint plate 16 and the forearm support plate 11 is moved accordingly, thus completing the locking of the angle of the patient's upper arm and forearm. During the postoperative recovery process, the relative angle of the upper arm and forearm can be adjusted as needed.
[0042] The radius and ulna position limiting mechanism 3 is installed on the inner side of the forearm support plate 11, and the radius and ulna position limiting mechanism 3 is equipped with a radius and ulna clamping mechanism 4.
[0043] The radius and ulna positioning mechanism 3 includes a transverse groove 31, an arc-shaped sliding groove 32, a positioning groove 33, a forearm end support plate 34, an anti-agitation guide surface 35, a limiting slider 36, and a locking bolt 37. Two transverse grooves 31 are respectively opened on the front and rear sides of the forearm support plate 11. Multiple arc-shaped sliding grooves 32 are equidistantly opened on the upper and lower sides of each transverse groove 31. Positioning grooves 33 are equidistantly opened on the left side of each arc-shaped sliding groove 32. A forearm end support plate 34 is provided inside the forearm support plate 11. The left end of the forearm end support plate 34 is provided with an anti-agglomeration guide surface 35. The anti-agglomeration guide surface 35 is used to prevent the left edge of the forearm end support plate 34 from aggravating the bottom of the forearm. The front and rear sides of the forearm end support plate 34 are respectively provided with two limiting sliders 36. The two limiting sliders 36 extend into the corresponding two transverse through grooves 31. The end of the limiting slider 36 away from the forearm end support plate 34 is threaded with a locking bolt 37. The hexagonal head of the locking bolt 37 presses against the outer side of the forearm support plate 11. Loosen the locking bolt 37 so that the hexagonal head of the locking bolt 37 is away from the outside of the forearm support plate 11. The limiting slider 36 can slide laterally along the corresponding transverse groove 31, thereby allowing the forearm end support plate 34 to move left and right relative to the forearm support plate 11. The forearm end support plate 34 needs to slide to the right end corresponding to the position of the patient's forearm near the palm, that is, the radial and ulnar clamping mechanism 4 corresponds to the end of the ulna and radius near the palm. Then, let the radial and ulnar clamping mechanism 4 initially clamp the end of the ulna and radius near the palm. When the radius and ulna clamping mechanism 4 limits the position of the ulna and radius near the palm, the ulna and radius are in a vertically corresponding distribution. At this time, the forearm can still move left and right relative to the radius and ulna clamping mechanism 4 for adjustment. When it is necessary to adjust the distribution of the ulna and radius near the palm, the forearm end support plate 34 is rotated relative to the forearm support plate 11. First, ensure that the limiting slider 36 corresponds to the arc groove 32. In order to make the limiting slider 36 correspond to the arc groove 32, the forearm end support plate may need to be rotated in the middle. The support plate 34 slides a short distance to the left or right relative to the forearm support plate 11. This distance does not affect the limiting effect of the radius and ulna clamping mechanism 4 on the end of the ulna and radius near the palm. After the forearm end support plate 34 is rotated to a suitable angle relative to the forearm support plate 11, the forearm end support plate 34 is moved to the left relative to the forearm support plate 11, allowing the limiting slider 36 to extend into the corresponding positioning groove 33. Then, the locking bolt 37 is tightened, so that the hexagonal head of the locking bolt 37 presses against the outer side of the forearm support plate 11, completing the forearm support plate 11 movement. After the arm end support plate 34 is fixed relative to the forearm support plate 11, the limiting slider 36 can no longer move along the arc groove 32. The radius and ulna clamping mechanism 4 further clamps and fixes the ends of the ulna and radius near the palm, thus completing the limiting and fixing of the distribution state of the ulna and radius. This prevents uncontrolled child movements from changing the state of the ulna and radius and affecting the recovery of the elbow joint. As the elbow joint recovers, the clamping force of the radius and ulna clamping mechanism 4 on the ulna and radius can be relaxed.
[0044] The radius and ulna clamping mechanism 4 includes a strip groove 41, a movable shaft 42, a radius and ulna splint 43, a nut 44, and a clamping bolt 45. Two strip grooves 41 are respectively opened on the front and rear sides of the bottom of the forearm end support plate 34. The two strip grooves 41 are movably connected to the bottom ends of the two radius and ulna splints 43 through two movable shafts 42. The tops of the two radius and ulna splints 43 are respectively bent relative to each other. Two nuts 44 are respectively embedded on the front and rear sides of the right end of the forearm end support plate 34. Each nut 44 is threadedly connected to two clamping bolts 45. The end of each clamping bolt 45 abuts against the side of the corresponding radius and ulna splint 43. Two radius and ulna splints 43 are used to clamp the sides of the ulna and radius. Twisting the clamping bolt 45 allows the clamping bolt 45 to move relative to the nut 44, so that the clamping bolt 45 abuts against the corresponding radius and ulna splint 43, and the two radius and ulna splints 43 move closer to each other to clamp and fix the sides of the ulna and radius. When the two radius and ulna splints 43 clamp the ulna and radius, the ulna and radius are in a corresponding vertical position. If the forearm end support plate 34 is rotated, it will also cause the end of the ulna and radius near the palm to rotate around the center of the forearm, thereby changing the distribution of the ulna and radius, so that the muscles at the elbow joint are in a proper recovery state. Since the clamping bolt 45 has a rigid clamping effect on the radius and ulna splint 43, the radius and ulna splint 43 will be tightly attached to the patient's forearm. Therefore, breathable gauze can be wrapped around the forearm or a breathable pad can be placed on the inside of the radius and ulna splint 43.
[0045] The radius and ulna clamping mechanism 4 also includes an inner arc groove 46, a forearm tightening band 47, a notch 48, a second hook and loop fastener male surface 49, an outer arc groove 410, a second hook and loop fastener female surface 411, and a second notch 412. The inner arc groove 46 is provided on the front side of the forearm end support plate 34. One end of the forearm tightening band 47 is connected to the inner arc groove 46, and the other end of the forearm tightening band 47 is connected to the second hook and loop fastener male surface 49. The outer arc groove 410 is provided on the rear side of the forearm end support plate 34. The second hook and loop fastener female surface 411 is provided in the outer arc groove 410. The second notch 412 is provided on the top rear side of the forearm end support plate 34 at the position corresponding to the outer arc groove 410. The notch 48 is provided on the top of the radius and ulna clamp 43 at the position corresponding to the inner arc groove 46. When the ulna and radius do not need to be fixed, for comfort, the radius and ulna splint 43 is no longer tightly attached to both sides of the patient's forearm. At this time, the forearm can move within the forearm end support plate 34. However, the forearm is prone to detach from the forearm end support plate 34 and the forearm support plate 11. Therefore, a forearm tightening strap 47 is provided. The forearm tightening strap 47 is tightened on the upper side of the forearm by means of the adhesion of the male side 49 and the female side 411 of the Velcro. The inner arc groove 46 is designed to facilitate the connection of the forearm tightening strap 47. The outer arc groove 410 is designed to avoid affecting the retraction of the radius and ulna splint 43 into the forearm support plate 11. The notch 48 and notch 412 are designed to avoid affecting the restraining effect of the forearm tightening strap 47 on the upper side of the forearm, allowing the forearm tightening strap 47 to fit tightly against the upper side of the forearm.
[0046] The radius and ulna clamping mechanism 4 also includes an anti-interference groove 413. The right end of the forearm support plate 11 is provided with an anti-interference groove 413 corresponding to the position of the clamping bolt 45. When not in use, the forearm end support plate 34 is retracted into the forearm support plate 11, and the clamping bolt 45 is in the anti-interference groove 413. The forearm end support plate 34 will not be retracted into the forearm support plate 11 due to interference from the outer end of the clamping bolt 45.
[0047] In use, the upper arm restraint plate 16 is restrained to the upper arm via the upper arm restraint assembly, and the upper arm restraint plate 16 is attached to the back of the upper arm. The forearm support plate 11 is used to support the bottom of the forearm near the elbow flexion point. The upper arm restraint plate 16 and the forearm support plate 11 are connected together by the first support plate 12, the second support plate 14 and the adjusting shaft 13. The adjusting shaft 13 corresponds to both sides of the elbow flexion point, so the position of the elbow flexion point can remain stable when the upper arm restraint plate 16 and the forearm support plate 11 move relative to each other. After adjusting the angle of the upper arm restraint plate 16 and the forearm support plate 11, the upper and lower arm angle adjustment mechanism 2 is used to maintain its angle stability. Due to the existence of the upper and lower arm angle adjustment mechanism 2, the angle of the upper arm and forearm can be continuously adjusted as needed during subsequent recovery. The radius and ulna position limiting mechanism 3 can extend and retract relative to the forearm support plate 11. To accommodate different children's arm lengths, the radius and ulna clamping mechanism 4 is designed to correspond to the ends of the ulna and radius near the palm. The radius and ulna clamping mechanism 4 clamps and fixes the ends of the ulna and radius near the palm. The radius and ulna state limiting mechanism 3 can be fixed after rotating a certain angle relative to the forearm support plate 11, thereby driving the radius and ulna clamping mechanism 4 to rotate and fix. This allows the ends of the ulna and radius near the palm to rotate and be fixed, thus maintaining a specific relative position of the ends of the ulna and radius near the palm, such as a vertical or front-back correspondence. This keeps the elbow joint stable and prevents the elbow joint from being pulled by the movement of the ends of the ulna and radius even though the elbow joint is fixed. This can address the common situation of postoperative care support for children's elbow joints.
[0048] Example 2, please refer to Figures 1 to 9 This embodiment provides a technical solution: an adjustable nursing support device for pediatric postoperative care. This embodiment is structurally similar to Embodiment 1, with the difference being:
[0049] It also includes a pressure massage component 5, which includes an airbag 51, an airbag protrusion 52, massage dots 53, an inflation / deflation port 54, and an air valve 55. An airbag 51 is positioned between the radius and ulna splint 43 and the forearm end support plate 34. An airbag protrusion 52 is evenly distributed on the side of the airbag 51 near the radius and ulna splint 43. Each airbag protrusion 52 is provided with a massage dot 53. The radius and ulna splint 43 has through holes corresponding to the airbag protrusions 52, and the airbag protrusions 52 extend into the corresponding through holes. An inflation / deflation port 54 is provided on the side of the airbag 51, and an air valve 55 is installed on the inflation / deflation port 54. The inflation / deflation port 54 and the air valve 55 pass through the plate holes on the forearm end support plate 34. Open the air valve 55 and inflate / deflate the airbag 51 through the inflation / deflation port 54. When the airbag 51 is inflated, it expands and applies pressure to the forearm through the radius and ulna splint 43. The airbag protrusion 52 on the airbag 51 also expands, allowing the protrusion 52 to apply a point massage to the forearm through the through hole on the radius and ulna splint 43 and the massage dots 53. When the airbag 51 is deflated, it relaxes. With the alternation of compression and relaxation, the massage operation on the forearm is completed, promoting blood circulation and relieving the discomfort caused by the pressure of the radius and ulna splint 43 on the forearm.
[0050] It also includes a function implementation module 6, which includes a detachable base box 61, an inflation component and a power supply component. The detachable base box 61 can be detachably installed at the bottom of the forearm support plate 11, and the inflation component and the power supply component are installed inside the detachable base box 61.
[0051] The functional implementation module 6 also includes a seat block 65, studs 66, and disassembly nuts 67. Four studs 66 are fixedly connected to the top four corners of the detachable base box 61, and four seat blocks 65 are fixedly connected to the bottom four corners of the forearm support plate 11. The four studs 66 pass through the seat holes on the four seat blocks 65 and are threadedly connected to the four disassembly nuts 67. The detachable connection between the detachable base box 61 and the forearm support plate 11 is achieved by means of the studs 66 and the disassembly nuts 67. In order to fit the detachable base box 61 and the forearm support plate 11, an arc-shaped fitting groove is provided on the top of the detachable base box 61.
[0052] The inflation assembly includes a pressurizing air pump 64, air hoses 68, and connectors 69. The pressurizing air pump 64 is installed inside the detachable base box 61. The air outlet of the pressurizing air pump 64 is connected to multiple air hoses 68. Each air hose 68 has a connector 69 at the end away from the pressurizing air pump 64. The connector 69 is connected to the inflation / deflation port 54. The pressurizing air pump 64 enables the inflation / deflation of the airbag 51. Specifically, a PLC controller is installed on the pressurizing air pump 64, and an inflation / deflation solenoid valve is installed on each air hose 68. The PLC controller controls the pressurizing air pump 64 and the inflation / deflation solenoid valves to achieve the inflation / deflation of the airbag 51. The specific control method adopts existing technology. The number of air hoses 68 is selected as needed, generally not less than four.
[0053] The power supply assembly includes a power supply 62, a charging port 63, a cable 610, and an electrical interface 611. The power supply 62 is also installed inside the detachable base box 61. The charging port 63 is provided on the outside of the power supply 62. The charging port 63 is connected to the power supply 62 through a charging circuit, and the power supply 62 can be charged through the charging port 63. The power supply 62 is connected to multiple electrical interfaces 611 through multiple cables 610. The specific number of cables 610 and electrical interfaces 611 can be selected as needed. The power supply 62 can supply power to the pressurized air pump 64, the inflation / deflation solenoid valve, and the PLC controller through the cables 610 and electrical interfaces 611.
[0054] Since arm massage is neither necessary nor a regular occurrence, the inflation and power supply components do not need to be constantly installed at the bottom of the forearm support plate 11. When massage is required, the detachable base box 61 is installed, allowing the inflation and power supply components to work together to achieve the massage function. The patient does not need to stay in one place during the massage, and the detachable base box 61 can be removed when not needed, reducing the load and improving comfort, which is suitable for postoperative rehabilitation care of pediatric patients.
[0055] The upper and lower arm support and clamping mechanism 1 also includes an upper arm heat therapy heater 111, a lower arm heat therapy heater 112, and a temperature control switch 113. The upper arm heat therapy heater 111 is embedded in the inner wall of the upper arm restraint plate 16, and the lower arm heat therapy heater 112 is embedded in the bottom inner wall of the lower arm support plate 11. The input terminals of the upper arm heat therapy heater 111 and the lower arm heat therapy heater 112 are both connected to the temperature control switch 113. The power supply 62 supplies power to the temperature control switch 113, the upper arm heat therapy heater 111, and the lower arm heat therapy heater 112 through the cable 610 and the electrical interface 611. The temperature control switch 113 controls the operation of the upper arm heat therapy heater 111 and the lower arm heat therapy heater 112. The control method adopts existing technology to apply heat to the upper arm and lower arm, promote blood circulation through heat application, and improve the postoperative recovery speed.
[0056] Example 3, please refer to Figures 1 to 9This embodiment provides a technical solution: an adjustable nursing support device for pediatric postoperative care. This embodiment is structurally similar to Embodiment 2, with the difference being:
[0057] It also includes a boom clamping and pressing mechanism 7, which includes a hinge 71, a boom clamping plate 72, an arc-shaped convex plate 73, a retaining groove 710, and a boom clamping plate clamping control assembly. The front and rear sides of the boom restraint plate 16 are respectively movably connected to the two boom clamping plates 72 through the hinge 71. The bottom ends of the two boom clamping plates 72 are respectively integrally formed and connected to the top ends of the two arc-shaped convex plates 73. The inner sides of the front and rear ends of the arc support plate 15 are respectively provided with two retaining grooves 710, and the bottom ends of the two arc-shaped convex plates 73 are respectively located in the two retaining grooves 710. The front and rear ends of the arc support plate 15 are respectively equipped with the boom clamping control assembly. The groove 710 on the arc support plate 15 limits the arc protrusion 73, thereby limiting the maximum opening angle of the two upper arm clamps 72. The upper arm clamp control assembly can bring the two upper arm clamps 72 closer to the sides of the upper arm, thereby better clamping the upper arm, improving the binding stability of the upper arm restraint plate 16 and the upper arm, and preventing the upper arm restraint plate 16 from affecting the support effect on the elbow joint relative to the upper arm movement.
[0058] The boom clamping control assembly includes a second nut 74 and a second clamping bolt 75. Two nuts 74 are installed at the front and rear ends of the arc support plate 15, and two clamping bolts 75 are threaded into the two nuts 74. The clamping bolts 75 clamp the arc protrusion plate 73, thereby clamping the boom with the two boom clamps 72 to achieve rigid clamping and fixation. This method is stable, but lacks buffering.
[0059] The boom clamping control assembly also includes an airbag slot 76, a compression airbag 77, an inflation / deflation port 78, and an air valve 79. Two airbag slots 76 are respectively formed within two retaining grooves 710, and a compression airbag 77 is installed in each airbag slot 76. An inflation / deflation port 78 is connected to the compression airbag 77, and an air valve 79 is installed on the inflation / deflation port 78. The inflation / deflation port 78 and the air valve 79 pass through holes in the arc-shaped convex plate 73, and the compression airbag 77 is inflated and deflated by the inflation assembly. The deflation operation uses existing technology. When inflating, pressing the airbag 77 pushes the arc-shaped convex plate 73, causing the two upper arm clamps 72 to clamp the upper arm. This provides a buffered clamping and fixing of the upper arm. However, this method has a relatively large free space for the upper arm to move after clamping. The two appropriate clamping methods mentioned above can be selected according to specific needs. If the airbag 77 is repeatedly inflated and deflated, the upper arm clamps 72 can also provide a squeezing, relaxing, and massaging effect on both sides of the upper arm, which is suitable for use in the later stages of rehabilitation.
[0060] Example 4, please refer to Figures 1 to 9This embodiment provides a technical solution: an adjustable nursing support device for postoperative care in children. This embodiment is structurally similar to Embodiment 3, with the difference being:
[0061] An elbow protection mechanism 8 is also provided, which includes an elbow-side arc-shaped protective plate 81, an adjusting screw 82, and a control flange 83. An arc-shaped guide groove is provided in the middle of the arc-shaped support plate 15, and the elbow-side arc-shaped protective plate 81 is slidably connected in the arc-shaped guide groove. The top of the elbow-side arc-shaped protective plate 81 is provided with a control flange 83. An adjusting screw 82 is threadedly connected to the middle of the outer side of the arc-shaped support plate 15, and the adjusting screw 82 abuts against the side of the elbow-side arc-shaped protective plate 81.
[0062] The elbow protection mechanism 8 also includes mounting plates 84, mounting bolts 85, bending frames 86, elbow bottom guard plate 87, infrared therapy lamp slots 88, and mounting holes 89. Two mounting plates 84 are respectively provided on the side of the two support plates 12 that are far apart from each other. The two mounting plates 84 are respectively fixedly connected to the two bending frames 86 by mounting bolts 85. The bottom ends of the two bending frames 86 are respectively fixedly connected to the front and rear sides of the right end of the elbow bottom guard plate 87. An infrared therapy lamp slot 88 is opened in the middle of the left end of the elbow bottom guard plate 87, and mounting holes 89 are respectively opened in the front and rear sides of the infrared therapy lamp slot 88 on the elbow bottom guard plate 87.
[0063] The elbow base plate 87 and the elbow side arc-shaped protective plate 81 provide protection for the elbow joint flexion point, preventing bumps and knocks from children's movements. This provides more comprehensive protection for the elbow joint and is more suitable for children. The infrared therapy lamp slot 88 and mounting hole 89 allow for the installation of therapy equipment, such as an infrared therapy lamp, at the elbow base plate 87. Combined with the power supply component in the function module 6, this enables therapy during children's activities without restricting their movement, making it suitable for post-operative care. When using the infrared therapy lamp or for elbow examination and dressing changes, the adjusting screw 82 can be loosened, and the elbow side arc-shaped protective plate 81 can be pulled upwards by manipulating the protruding edge 83, providing more installation space on the upper left side of the elbow base plate 87. At other times, the elbow side arc-shaped protective plate 81 is positioned close to the left side of the elbow base plate 87 for comprehensive elbow protection.
