Description

Technical Field

[0001] This invention relates to a suspension device, and more particularly to a suspension device for fracture rehabilitation treatment. Background Technology

[0002] After a fracture, it is often necessary to elevate the affected limb. The main purpose of elevating the affected limb is to reduce swelling, relieve pain, and promote tissue repair. By using gravity to reduce the accumulation of blood and body fluid in the injured area, vascular pressure can be reduced, circulation can be improved, thereby accelerating recovery and reducing the risk of complications. Elevating the affected limb requires the use of a suspension device.

[0003] For example, the Chinese patent publication number for an adjustable lifting tripod includes a frame, two supporting vertical rods, a suspension horizontal rod, two vertical adjustment mechanisms, two horizontal locking structures, two moving mechanisms, and two bandages. This utility model's adjustable lifting tripod has the advantages of simple structure, ease of use, and strong practicality for medical care. It solves the problem of bandage contraction and subsequent compression of the feet due to the weight of the patient's lower limbs, making it difficult for medical staff to treat the patient. Furthermore, foot compression can easily lead to iatrogenic injuries in fracture patients. Alternatively, two identical devices are needed to solve this problem, which makes it difficult for medical staff to ensure the patient's legs are properly positioned and separated during lower limb disinfection and examination, resulting in incomplete medical care. This patent has the following problems: Firstly, some patients with unilateral lower limb fractures can get out of bed on their own to perform daily activities such as urination with the help of crutches, but because the fractured limb is treated with suspension, the patients themselves have difficulty taking the limb off the suspension and need the assistance of additional medical or caregivers. Secondly, the device occupies a lot of space when it is not in use, making storage a major problem. Third, because patients with lower limb fractures generally have difficulty bending their legs, but the support rods of the device are placed on both sides of the bed, the patient's lower limbs will interfere with the support rods, affecting the patient's ability to get out of bed directly. Summary of the Invention

[0004] The purpose of this invention is to provide a suspension device for fracture rehabilitation treatment, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a suspension device for fracture rehabilitation treatment, comprising a U-shaped support frame, the U-shaped support frame comprising a base, a support rod, and a cantilever, wherein an insertion groove is provided near the front edge of the cantilever, a support beam is inserted and installed in the insertion groove, a connecting slider is slidably installed on the support beam, a drive motor is fixedly connected to the front of the connecting slider, a take-up reel is fixedly connected to the output end of the drive motor, a connecting rope is wound in the take-up reel, a lifting device is fixedly connected to the other end of the connecting rope, and a control host is fixedly connected to the top of the connecting slider.

[0006] Preferably, the lower end of the support rod is fixedly connected to the base, and the cantilever is fixedly connected to the support rod near the rear end.

[0007] Preferably, a limiting groove is formed on the cantilever, a return spring is fixedly connected in the limiting groove, a limiting pin is fixedly connected to the other end of the return spring, and a displacement handle is fixedly connected to the limiting pin.

[0008] Preferably, the end of the limiting pin is inserted into the insertion slot, and the limiting pin is slidably installed in the limiting groove.

[0009] Preferably, the supporting crossbeam has limiting holes at the positions near both ends, and the limiting holes cooperate with the limiting pins.

[0010] Preferably, the drive motor is equipped with a power-off locking mechanism.

[0011] Preferably, a friction block is embedded in the support beam, and the friction block is roughened.

[0012] Preferably, the connecting slider has a connecting groove, which is larger than the supporting crossbeam.

[0013] Preferably, the control host is equipped with a control module, a power module, a wireless module, and a built-in power supply.

[0014] Preferably, an antenna is fixedly connected to the control host.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The control host can remotely control the start and stop of the drive motor, allowing the patient to freely control the start and stop of the drive motor while lying down. When the patient needs to get out of bed, they can control the sling to lower the suspended lower limb without the need for additional medical staff assistance. This increases the patient's freedom of movement while reducing the workload of medical staff. Furthermore, the suspension height of the fractured lower limb can be freely adjusted according to the patient's own condition.

[0016] 2. A U-shaped support frame consisting of a base, support rods, and cantilever is placed on both sides of the hospital bed. Because the U-shaped support frame is U-shaped as a whole, its vertical support rods are close to the rear end of the hospital bed, which can minimize interference with the fractured lower limbs when the patient gets out of bed and affect the patient's normal getting out of bed activities.

[0017] 3. The connecting slider, supporting beam, and U-shaped support frame can be easily disassembled and broken down into individual parts, reducing the overall size of the device and facilitating storage or transportation. Attached Figure Description

Detailed Implementation

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0022] Example 1 A suspension device for fracture rehabilitation includes a U-shaped support frame, which includes a base 1, a support rod 101, and a cantilever 102. A insertion groove 103 is provided near the front edge of the cantilever 102. A support beam 3 is inserted and installed in the insertion groove 103. A connecting slider 4 is slidably installed on the support beam 3. A drive motor 402 is fixedly connected to the front of the connecting slider 4. A take-up reel 403 is fixedly connected to the output end of the drive motor 402. A connecting rope 404 is wound inside the take-up reel 403. A lifting device 405 is fixedly connected to the other end of the connecting rope 404. A control host 5 is fixedly connected to the connecting slider 4.

[0023] In this embodiment, the support beam 3 is inserted into the insertion slot 103, thereby installing the support beam 3 between two U-shaped support frames. The connecting slider 4 is slidably installed on the support beam 3, and the support beam 3 supports the connecting slider 4 in a suspended state. The U-shaped support frames are set on both sides of the hospital bed. Since the U-shaped support frame is U-shaped, its vertical support rod 101 is close to the rear end of the hospital bed, which can minimize interference with the fractured lower limb when the patient gets out of bed, thus avoiding affecting the patient's normal ambulation. The sling 405 can be used to hook bandages, etc., and the binding straps can be used to bind the lower end of the fracture. The drive motor 402 is started to drive the winding reel 403 to rotate. The winding reel 403 rotates to wind up or release the connecting rope 404. The connecting rope 404 drives the sling 405 to move. First, the height of the sling 405 can be freely adjusted. Then, according to the patient's own situation, the suspension height of the fractured lower limb can be freely adjusted. Second, the control host 5 is equipped with a wireless module, which can be controlled by a remote control or an app. The control host 5 is electrically connected to the drive motor 402, and the control host 5 can control the start of the drive motor 402. This allows the patient to freely control the start and stop of the drive motor 402 while in bed. When the patient needs to get out of bed, he / she can control the sling 405 to lower the suspended lower limb without the need for additional medical staff assistance. This increases the patient's freedom of movement while reducing the workload of medical staff.

[0024] Example 2 The lower end of the support rod 101 is fixedly connected to the base 1. The cantilever 102 is fixedly connected to the support rod 101 near the rear end. A limiting groove 2 is provided on the cantilever 102. A return spring 201 is fixedly connected in the limiting groove 2. A limiting pin 202 is fixedly connected to the other end of the return spring 201. A shift handle 203 is fixedly connected to the limiting pin 202. The end of the limiting pin 202 is inserted into the insertion groove 103. The limiting pin 202 is slidably installed in the limiting groove 2. A limiting hole 302 is provided near the two ends of the support beam 3. The limiting hole 302 and the limiting pin 202 cooperate with each other.

[0025] In this embodiment, a U-shaped frame is formed by the base 1, the support rod 101, and the cantilever 102, so that the support rod 101 is positioned as far back as possible to avoid interference with the patient's lower limbs. The return spring 201 can provide a certain pushing force to the limiting pin 202. When the limiting pin 202 is pushed, it will insert into the limiting hole 302, thereby fixing the support beam 3 inside the insertion slot 103 and fixing the support beam 3 between the two U-shaped support frames to avoid the problem of the support beam 3 slipping off. The shift handle 203 can be used to drive the limiting pin 202 to move.

[0026] Example 3 The drive motor 402 is equipped with a power-off locking mechanism. A friction block 301 is embedded in the support beam 3. The friction block 301 is roughened. A connecting slide 401 is opened in the connecting slider 4. The connecting slide 401 is larger than the support beam 3. The control host 5 is equipped with a control module, a power module, a wireless module, and a built-in power supply. An antenna 501 is fixedly connected to the control host 5.

[0027] In this implementation scheme, the locking mechanism built into the drive motor 402 ensures that the drive motor 402 is in a power-off state during normal use. This locking mechanism restricts the rotation of the output end of the drive motor 402, thereby maintaining the original height of the lifting device 405 and preventing it from shifting downwards due to force after power failure. The control host 5 has a built-in power supply that needs to be charged according to power usage. The built-in power supply avoids the need for cumbersome wiring. The control module, in conjunction with the wireless module, enables remote control of the start and stop of the drive motor 402. The antenna 501 is used for signal connection, and the connecting groove 401 is slightly larger than the supporting beam 3. Figure 5 As shown, when the patient's lower limb is suspended, the weight of the lower limb is transmitted to the connecting slider 4. At this time, the connecting slider 4 will press down on the supporting beam 3, thereby causing the top of the connecting groove 401 to fit together with the friction block 301. The friction force restricts the connecting slider 4 from moving freely left and right. When the patient's lower limb is not suspended, the connecting slider 4 can be easily lifted up to make the top of the connecting groove 401 contact and separate from the friction block 301. Then, without friction, the connecting slider 4 can slide easily left and right, making it easy to adjust the position of the connecting slider 4.

[0028] The working principle and usage process of this invention are as follows: When in use, the U-shaped support frame needs to be set on both sides of the patient's bed. Depending on the number of fractures in the patient's lower limbs, one or two connecting sliders 4 are fitted onto the support beam 3. Then, the support beam 3 is inserted into the insertion slot 103, and the limiting pin 202 is inserted into the limiting hole 302 to complete the assembly of the device. The patient's lower limbs are tied with bandages, and the other end of the bandages is hung on the sling 405. The drive motor 402 is started to drive the winding reel 403 to wind up the connecting rope 404. The connecting rope 404 will drive the sling 405 to move upward, thereby using the bandages to suspend the patient's lower limbs, which is conducive to the healthy recovery of the patient's lower limbs.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
