[0002] Burn is a kind of tissue damage caused by various physical or chemical factors.

[0003] In the healing process of patients with large area burns, the part of the limbs adhering to the bed surface is deepened due to skin compression, which leads to prolonged healing time, so the affected limb needs to be raised to separate it from the bed surface and increase the healing speed.

[0004] In actual implementation process, although the suspension assembly is used to suspend the burned part of the patient to prevent the wound from being pressed for a long time and causing aggravation risk, the wound of the burn patient needs to be supported, which is usually located in the limbs, and the device of the suspension rehabilitation training device is bulky, and the suspension belts in the suspension assembly are numerous, which is easy to cause the wound to be aggravated by accidentally touching other suspension belts during the suspension of the affected limb, and the suspension operation is messy and complex.

[0005] Therefore, the present application provides a portable burn rehabilitation suspension protection device and method to solve the above problems. SUMMARY

[0006] To solve the above problems, the present application provides a portable burn rehabilitation suspension protection device and method, which uses a support plate and a soft pad to support the affected limb and then uses an air bag to fix the affected limb, thereby reducing the risk of collision of the affected limb and improving the convenience of suspending the affected limb.

[0007] In order to achieve the above object, the technical scheme of the present application is as follows: A portable burn rehabilitation suspension protection device, comprising a base, a hollow column fixedly connected to the top of the base, a sliding column slidingly fitted in the hollow column, the top of the sliding column extending out of the hollow column, a crossbar fixedly connected to the top of the sliding column, two support plates fixedly connected to the bottom of the crossbar away from the sliding column, one of the support plates being fixedly connected to the bottom of an arc-shaped soft pad, the side of the arc-shaped soft pad away from the connection with the support plate being provided with a locking assembly for fixing the arc-shaped soft pad, air bags fixedly connected to the bottom of the support plates away from each other, an air pump fixedly connected to the top of the crossbar near the arc-shaped soft pad, the air pump and the air bags being in communication, and the air pump being signal-connected to a controller; the affected limb is placed on the arc-shaped soft pad, the locking assembly is used to preliminarily fix the affected limb, and the air pump is controlled by the controller to supply air to the air bags to fix the affected limb.

[0008] The technical principle of the above scheme is as follows: the affected limb is slightly lifted and placed on the arc-shaped soft pad, the locking assembly is triggered by the gravity of the affected limb to preliminarily fix the affected limb, and then the air pump is controlled by the controller to inflate the air bags, so that the air bags are in close contact with the surface of the affected limb to complete the fixation of the affected limb.

[0009] The above scheme has the following beneficial effects: compared with the device using a combination of multiple suspension belts, the present scheme supports the affected limb by a single arc-shaped soft pad, avoiding the risk of secondary injury to the affected limb caused by the entanglement of multiple suspension belts; at the same time, the present scheme realizes the self-adaptive locking of the affected limb through the locking assembly, and can adjust the fixing force according to the movement changes of the affected limb, thereby preventing the affected limb from sliding and reducing the secondary injury caused by the sliding of the affected limb.

[0010] Further, the locking assembly comprises a first support and a second support, the first support and the second support are fixedly connected to the side wall of the support plate away from the fixed side of the arc-shaped soft pad, a rotating shaft is rotatably connected to the first support, a hanging rod and a first gear are fixedly connected to the rotating shaft, a through hole is opened in the side of the hanging rod away from the rotating shaft, a rotating shaft is rotatably connected to the second support, the rotating shaft extends out of the second support on one side, a connecting rod is fixedly connected to the side of the rotating shaft away from the second support, the other end of the connecting rod is hingedly connected to the bottom of the arc-shaped soft pad, a spring is fixedly connected to the end of the rotating shaft away from the second support, the other end of the spring is fixedly connected to the bottom of the connecting rod, a second gear corresponding to the first gear is fixedly connected to the side of the rotating shaft away from the connecting rod, a toothed chain is engaged with the second gear, the top of the toothed chain is engaged with the first gear, a pull rope is fixedly connected to the middle of the connecting rod, an arc-shaped clamp plate is fixedly connected to the other end of the pull rope, the top of the arc-shaped clamp plate is hingedly connected to the bottom of the support plate near the first support, and a hanging rope is fixedly connected to the side of the arc-shaped soft pad away from the sliding column and passes through the through hole in the hanging rod.

[0011] Beneficial effects: Some patients with severe limb trauma cannot independently raise the limb height. Through the design of the hanging rod and the hanging rope, the affected limb is placed on the arc-shaped soft pad. The gravity of the affected limb moves the arc-shaped soft pad downward, and at the same time pushes the connecting rod to move downward. At this time, the connecting rod rotates counterclockwise around the rotating shaft as the center, thus driving the rotating shaft and the second gear to rotate counterclockwise. Through the meshing of the tooth chain with the first gear and the second gear, the first gear drives the rotating shaft and the hanging rod to rotate counterclockwise, and then the hanging rod and the through hole rotate upward, pulling the hanging rope to move upward, so that the arc-shaped soft pad supports the affected limb upward and locks the arc-shaped soft pad at the same time, avoiding the situation that the patient can only be supported by suspension when the affected limb is raised to the specified height. At the same time, when the connecting rod moves downward, it drives the middle pull rope to move synchronously, and then generates a pulling force on the bottom of the arc-shaped clamping plate through the pull rope, so that the bottom of the arc-shaped clamping plate moves closer to the connecting rod, and at the same time, the top of the arc-shaped clamping plate moves closer to the affected limb, preliminarily clamping and fixing the affected limb.

[0014] Further, the side close to each other of the air bag and the top of the arc-shaped soft pad are fixedly connected with a pressure sensor, and the pressure sensor is signal connected with the controller.

[0015] Beneficial effects: According to the real-time monitoring of the pressure sensor, the pressure of the contact surface between the affected limb and the air bag and the arc-shaped soft pad is adjusted to avoid the aggravation of the wound caused by excessive pressure on the affected limb.

[0016] Further, the side close to each other of the air bag and the top of the arc-shaped soft pad are fixedly connected with a pressure sensor, and the pressure sensor is signal connected with the controller.

[0017] Beneficial effects: When the pressure value remains unchanged, the vibrator starts to vibrate through the controller, which promotes blood circulation on the contact surface between the affected limb and the soft pad and the air bag, and avoids the aggravation of the wound caused by long-term pressure on the skin of the affected limb.

[0018] Further, the bottom of the base is provided with a plurality of universal wheels.

[0019] Beneficial effects: Through the design of the universal wheel, the use position of the arc-shaped soft pad is more flexible, and the convenience of suspending the affected limb is improved.

[0021] Beneficial effects: Through the antibacterial coating, the risk of bacterial growth on the contact surface between the affected limb and the soft pad is reduced, thereby reducing the risk of aggravating the wound on the affected limb.

[0022] Further, a portable burn rehabilitation suspension protection method comprises the following steps:

[0023] S1: placing the affected limb: placing the affected limb on the arc-shaped soft pad;

[0024] S2: locking: self-adaptive locking through the locking assembly;

[0025] S3: fixing the affected limb: inflating the air bag by the air pump controlled by the controller to fix the affected limb;

[0027] S5: automatic adjustment: according to the signal feedback of the pressure sensor, filling the gas by the air pump controlled by the controller to reinforce, and vibrating the vibrator to massage the affected limb.

[0028] Further, the output pressure of the air pump in S3 is 12-15kPa.

[0029] Further, in S5, when the pressure sensor has no pressure change for 5 minutes, the controller controls the vibrator to start vibrating, and the vibration frequency is 10-35Hz.

[0030] Beneficial effects: the arc-shaped soft pad supports the affected limb, the air bag is used to fix the affected limb to avoid sliding during lifting, the pressure sensor is used to monitor the pressure value in real time during lifting to control the gas amount in the air bag and the vibration of the vibrator, reduce the risk of aggravating the affected limb trauma, and improve the comfort of the patient.

[0045] Because the patient has difficulty in lifting the affected limb independently or even cannot lift it independently due to burns, auxiliary lifting is needed, as shown in the accompanying Figure 3As shown, the hollow column 2 is welded with an electric control cylinder 11 at the bottom wall, the model of the electric control cylinder 11 is preferably SMC LEFS50B-500 of Japan, the output shaft of the electric control cylinder 11 is welded with the bottom end of the sliding column 3, and the electric control cylinder 11 is signal connected with the controller; and the bottom of the base 1 is provided with a plurality of lockable universal wheels 12, the arc-shaped soft pad 6 is moved to the appropriate position by moving the base 1 to support the affected limb, so as to be suitable for patients with different burn sites;

[0046] The protective effect of lifting the affected limb is to prevent the skin from being pressed to cause the wound to be aggravated by the long-term contact of the affected limb with the bed surface, and during the process of lifting the affected limb, the contact surface of the affected limb with the arc-shaped soft pad 6 and the air bag 7 is also long-term pressed, in order to prevent the pressure of the contact surface of the affected limb with the arc-shaped soft pad 6 and the air bag 7 from continuously causing the wound of the contact surface to be aggravated, the air bag 7 is fixedly connected with a pressure sensor on the side close to each other and the top of the arc-shaped soft pad 6, the model of the pressure sensor is preferably MS5837-30BA of TE Connectivity, the pressure sensor is signal connected with the controller, and the side close to each other of the air bag 7 and the top of the arc-shaped soft pad 6 are provided with a vibrator corresponding to the pressure sensor, the model of the vibrator is preferably JDH-280-04115 of Jinlong Electromechanical, the vibrator is signal connected with the controller, and the contact surface of the arc-shaped soft pad 6 with the affected limb is provided with an antibacterial coating, the material of the antibacterial coating is preferably a nano-silver-chitosan compound, so as to reduce the risk of infection of the affected limb.

[0047] The specific implementation process is as follows: since patients with large area burns usually need to be bedridden and have low self-movement ability, the limb wound is in contact with the bed surface for a long time and the skin of the affected limb is in a compressed state during the bedridden process, so the affected limb needs to be lifted to play a protective role. First, the base 1 needs to be moved to the side close to the affected limb, and the universal wheel 12 is locked to fix the position of the base 1 after the position is confirmed. Then, the controller controls the electric cylinder 11 to operate, and the electric cylinder 11 drives the sliding column 3 to slide vertically, controls the lifting of the cross bar 4, and then controls the height of the support plate 5 and the arc-shaped soft pad 6. After adjusting the arc-shaped soft pad 6 to be in contact with the bed surface, the medical staff lifts the affected limb and places it on the arc-shaped soft pad 6. The controller controls the electric cylinder 11 to raise the cross bar 4 to the specified height. During the lifting process, the gravity of the affected limb exerts a downward pressure on the arc-shaped soft pad 6, causing the arc-shaped soft pad 6 to move downward and push the bottom of the connecting rod 13 to move downward, thereby causing the connecting rod 13 to rotate counterclockwise around the rotating shaft 17. Since the connecting rod 13 and the second gear 21 are both welded to the rotating shaft 17, the connecting rod 13 synchronously drives the rotating shaft 17 and the second gear 21 to rotate counterclockwise. Through the meshing of the tooth chain 22 with the first gear 20 and the second gear 21, the first gear 20 rotates counterclockwise. Since the first gear 20 and the hanging rod 9 are both welded to the rotating shaft 18, the first gear 20 drives the rotating shaft 18 and the hanging rod 9 to rotate counterclockwise synchronously, thereby causing the through hole 23 on the hanging rod 9 to move upward, pulling the hanging rope 10 to move upward, and causing the arc-shaped soft pad 6 to move upward to provide support to the affected limb. When the connecting rod 13 rotates downward, it will cause the pull rope 19 to move closer to the connecting rod 13, thereby exerting a pulling force on the bottom of the arc-shaped clamp 14 through the pull rope 19, causing the bottom of the arc-shaped clamp 14 to move closer to the connecting rod 13 and the top of the arc-shaped clamp 14 to move closer to the affected limb, thereby exerting pressure on the affected limb to preliminarily fix it. Then, the controller controls the air pump 8 to inflate the air bag 7, causing the air bag 7 to expand to fit the skin of the affected limb. According to the pressure signal output by the pressure sensor on the air bag 7, the pressure of the air bag 7 on the affected limb is determined. When the pressure value increases to a level that can fix the affected limb without causing injury to the wound, the controller controls the air pump 8 to stop inflating.

[0048] When the affected limb is continuously lifted, the pressure sensor on the arc-shaped soft pad 6 can monitor the force on the skin of the affected limb in real time. When the pressure value does not change for a period of time, the time during which the pressure value does not change is preferably set to 5 minutes. The corresponding vibrator is started through the controller. For acute patients, a low-frequency vibration of 10-15 Hz is adopted, and the single time length is ≤2 minutes. For rehabilitation patients, a medium-frequency vibration of 20-35 Hz is adopted, and the single time length is ≤5 minutes. The vibration frequency and time length are controlled to ensure that the pressure on the contact surface of the affected limb can be relieved without aggravating the injury to the affected limb.

[0049] When the affected limb is lifted, both the affected limb and the arc-shaped soft pad 6 are in an inclined state. If the affected limb is lifted for a long time, the affected limb may slip due to the secretion of body fluids, and the wound may be further injured during the slipping process. When the affected limb slips for a long time, the pressure on the arc-shaped soft pad 6 is the gravity of the affected limb and the pressure caused by the slipping, so that the pressure on the arc-shaped soft pad 6 increases, and the pressure of the arc-shaped soft pad 6 on the connecting rod 13 also increases. Through the meshing action of the first gear 20, the second gear 21 and the toothed chain 22, the rotating shaft 18 and the hanging rod 9 rotate upward, thereby increasing the supporting force of the arc-shaped soft pad 6. At the same time, the movement of the connecting rod 13 increases the tension of the pull rope 19 on the arc-shaped clamping plate 14, so that the top of the arc-shaped clamping plate 14 further approaches the affected limb, and the pressure of the arc-shaped clamping plate 14 on the affected limb is increased, thereby fixing the affected limb and preventing the affected limb from slipping and causing further injury to the affected limb;

[0050] The base 1 is controlled by the universal wheel 12, so that the arc-shaped soft pad 6 can be moved to be suitable for suspending burns at different positions. Through the design of a single arc-shaped soft pad 6, the traditional problem of multiple suspension belts being entangled and further injuring the affected limb is avoided. In addition, the arc-shaped soft pad 6 is detachably installed on one side, which reduces the initial lifting height of the affected limb, reduces the burden on the affected limb, and improves the operation convenience. In addition, the pressure sensor can monitor the pressure and fixation of the contact surface of the affected limb in real time, and the fixation pressure of the affected limb can be adjusted and the pressure can be relieved through the feedback of the pressure value, so as to avoid the affected limb from slipping and the skin from being further injured due to pressure.

[0051] According to the convenient burn rehabilitation suspension protection device of embodiment 1, the traditional suspension rehabilitation training device is compared, and the specific experiment is as follows:

[0052] The purpose of the experiment is to improve the operation efficiency and reduce the risk of accidental touch during the fixation of the affected limb. The probability of slipping or colliding of the affected limb in the suspended state is reduced. The dynamic adjustment effect of the pressure of the contact surface of the affected limb is improved. The subjective comfort of the patient and the operation satisfaction of the nursing staff are improved.

[0053] The experimental steps are as follows: 1. Sample grouping: 40 cases of Ⅱ-Ⅲ degree burn patients (20 cases of upper limbs and 20 cases of lower limbs) are randomly divided into two groups:

[0054] Experimental group: use the device of embodiment 1 (arc-shaped soft pad + air bag fixation + self-adaptive locking)

[0055] Control group: use the traditional XY-SET-IIB suspension rehabilitation training device (multiple suspension belt combination)

[0056] 2. Operation process:

[0057] Initial setting:

[0058] Experimental group: adjust the height of the device to the level of the bed surface, place the affected limb on the arc-shaped soft pad, and start the self-adaptive locking and air bag inflation (12 kPa).

[0059] Control group: according to the position of the affected limb, install narrow sling + T-shaped belt combination and adjust the tension.

[0060] Suspension stage:

[0061] Both groups will lift the affected limb to 30 cm above the bed surface, maintain for 2 hours.

[0062] Record the displacement of the affected limb, contact surface pressure value (pressure sensor collection) and patient pain score (0-10) every 20 minutes.

[0063] Interference test:

[0064] Simulate the patient's turning action (affected limb horizontal movement ± 15°), record the time spent by the device adjustment and the stability of the affected limb.

[0065] 3. Data collection:

[0066] Objective indicators:

[0067] Operation time (initial fixation + height adjustment)

[0068] Affected limb slip distance (monitored by laser displacement sensor)

[0069] Maximum contact surface pressure value and fluctuation range

[0070] Number of accidental entanglement events

[0071] Subjective indicators:

[0072] Patient comfort score (Likert 5-point scale)

[0073] Nursing staff operation difficulty score (1-5, 5 being the most complex)

[0074] Experimental data:

[0075]

[0076]

[0077] Experimental conclusion:

[0078] Safety is significantly improved: the experimental group completely avoids the risk of entanglement of the suspension belt (0 accidental events) through the closed fixation design of the arc-shaped soft pad + air bag, while the control group has 60% of patients with accidental touch due to the crossing of multiple suspension belts. The contact surface pressure is reduced by 52% (9.9kPa vs 19.2kPa), and the experimental group reduces the pressure fluctuation range by 69% through dynamic inflation adjustment, effectively preventing pressure ulcers.

[0079] Operation efficiency optimization: The initial operation time of the experimental group was shortened by 76% (2.5 minutes vs 10.6 minutes), and the adaptive locking mechanism reduced the need for manual intervention. The nursing staff's operation difficulty score decreased by 66%, confirming the convenience advantage of the device.

[0080] Stability and comfort: The sliding distance of the affected limb was controlled within 1.5 mm (the control group reached 12.3 mm), and the adaptive reinforcement function of the air bag prevented slipping. Vibration massage (10-35 Hz) improved patient comfort scores by 65%, especially for patients in the rehabilitation period who reported that low-frequency vibration could relieve muscle stiffness.

[0081] Example 2:

[0082] As shown in the accompanying Figure 1 A portable burn rehabilitation suspension protection method includes the following steps:

[0083] S1: Place the affected limb: Place the affected limb on the arc-shaped soft pad 6;

[0084] S2: Lock: Adaptive locking through the locking assembly;

[0085] S3: Fix the affected limb: Control the air pump 8 to inflate the air bag 7 through the controller, so that the air bag 7 expands to fix the affected limb;

[0086] S4: Adjust the height: Adjust the suspension height of the affected limb by controlling the electric cylinder 11 to adjust the lifting of the sliding column 3 through the controller;

[0087] S5: Automatic adjustment: According to the signal feedback of the pressure sensor, fill the gas through the controller to control the air pump 8 to reinforce, and control the vibrator to vibrate to massage the affected limb;

[0088] The output pressure of the air pump 8 in S3 is 12-15 kPa; When the pressure sensor does not change for 5 minutes in S5, the controller controls the vibrator to start vibrating, and the vibration frequency is 10-35 Hz

[0089] The specific implementation process is as follows: the affected limb is placed above the arc-shaped soft pad 6, the lifting height of the affected limb is controlled by the electric control cylinder 11, the arc-shaped soft pad 6 is locked by the hanging rod 9 and the hanging rope 10, the arc-shaped clamping plate 14 preliminarily fixes the affected limb, then the air pump 8 is controlled by the controller to inflate the air bag 7, so that the air bag 7 is inflated to be in close contact with the affected limb to fix the affected limb; during the process of keeping the affected limb raised, the support force of the arc-shaped soft pad 6 and the pressure of the arc-shaped clamping plate 14 on the affected limb are adaptively adjusted by the pressure change of the arc-shaped soft pad 6 and the connecting rod 13 to avoid the affected limb from slipping and aggravating the injury; and the vibrator is controlled to vibrate according to the pressure condition of the arc-shaped soft pad 6, since the Burns Pathology (third edition) page 178 explains that vibrations below 10 Hz can cause tissue resonance damage, and high-frequency vibrations above 35 Hz can activate pain C fibers, therefore the vibration frequency is controlled to be 10-35 Hz.

[0090] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Other different forms of changes or variations can be made on the basis of the above description for those skilled in the art. All the embodiments do not need and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
