Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an orthopedic splint. Background Technology

[0002] When a finger is fractured, a finger fracture rehabilitation splint is generally used to immobilize it. A finger fracture rehabilitation splint is a commonly used medical device for treating finger fractures. It can provide stable support and restrict finger movement, helping the fracture site to heal. Current finger fracture rehabilitation splints generally consist of a wrist strap, a fixation plate, a placement plate, and Velcro. By placing the finger inside the splint, the Velcro is used to fix the finger to the splint, thereby helping the fracture site to heal.

[0003] However, the main function of traditional orthopedic finger splints is to fix the finger position and maintain the stability of the bones. Prolonged fixation can easily cause many problems, such as poor local blood circulation in the finger. This can not only slow down the wound healing process, but may also lead to complications such as muscle atrophy and joint stiffness, which will have an adverse effect on the recovery of the patient's finger function.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution: an orthopedic splint, comprising:

[0032] The finger clamp includes a lower panel 1 and an upper panel 2, which are long, arc-shaped pieces that can clamp the upper and lower sides of the finger respectively. The front ends of the lower panel 1 and the upper panel 2 are connected by a bending plate 3.

[0033] A fixing strap is provided on the outside of the finger clamp, and the finger clamp is fixed to the finger by the fixing strap;

[0034] The air pressure chamber 9 is formed inside the lower plate 1 and the upper plate 2. Multiple air outlets 10 are provided on the opposite sides of the lower plate 1 and the upper plate 2. One end of the air outlet 10 is connected to the air pressure chamber 9, and the other end of the air outlet 10 extends to the opposite side of the lower plate 1 and the upper plate 2 and is connected to a soft air bag 11. An opening connected to the air pressure chamber 9 is provided on the opposite side of the lower plate 1 and the upper plate 2. A flexible membrane 8 that can expand, contract and seal the opening is sealed at the port of the opening.

[0035] Specifically, the finger clamp consists of a lower panel 1 and an upper panel 2, forming a long, arc-shaped structure that clamps onto the upper and lower sides of the finger, respectively. The front ends are connected by a bending plate 3, forming a wrapping structure around the finger. A fixing strap secures the finger clamp to the finger. An air pressure chamber 9 is located inside the lower panel 1 and upper panel 2. One end of an air outlet 10 communicates with the air pressure chamber 9, and the other end connects to a soft air bag 11, which can contact the finger. The flexible membrane 8 is sealed at the opening on the opposite side of the lower panel 1 and the upper panel 2, which communicates with the air pressure chamber 9. When the air pressure inside the air pressure chamber 9 changes, the flexible membrane 8 can expand or contract, thereby changing the air pressure inside the air pressure chamber 9 and causing the soft air bag 11 to change accordingly, such as expanding or contracting, applying or changing pressure to the finger. This design, while achieving finger fixation, allows for adjustment of the pressure on the finger as needed through the cooperation of the air pressure chamber 9, the air outlet 10, the soft air bag 11, and the flexible membrane 8, promoting local blood circulation in the finger. This solves the problem of poor blood circulation caused by prolonged fixation of traditional splints in the background technology, helps reduce complications such as muscle atrophy and joint stiffness, and facilitates the recovery of finger function in patients. The arc-shaped design of the finger splint conforms to the shape of the finger, improving wearing comfort.

[0036] It should be noted that, as another massage method, when using it, the patient can hold the entire splint with their other hand and repeatedly squeeze it. During the squeezing process, the hand squeezes the flexible membrane 8, and the gas inside the flexible membrane 8 will enter the air pressure chamber 9, disturbing the gas flow in the air pressure chamber 9, thereby causing the soft air bag 11 to repeatedly expand or contract, further improving the comfort of the massage. At the same time, it can be adjusted according to the patient's needs.

[0037] See Figure 6 An air inlet chamber 12 is provided inside the bent plate 3. The air inlet chamber 12 is connected to the air pressure chamber 9. An air inlet hole 13 is installed on the side wall of the bent plate 3, and a valve 14 is installed on the air inlet hole 13.

[0038] Specifically, by opening valve 14, air can be injected or released into air inlet chamber 12 through air inlet 13, thereby changing the air pressure in air pressure chamber 9 and realizing the regulation of pressure in soft air bag 11.

[0039] The air inlet chamber 12, air inlet 13 and valve 14 provide a convenient way to adjust the air pressure in the air pressure chamber 9. Medical staff can flexibly control the air pressure according to the patient's actual situation, further optimize the effect of promoting blood circulation in the patient's fingers, and improve the flexibility and targeting of the splint.

[0040] See Figure 6 A valve plate 15 is provided inside the air intake chamber 12, which can slide along its inner wall in a sealing manner. The valve plate 15 divides the air pressure chamber 9 into a left chamber and a right chamber.

[0041] It should be noted that a sealing film is provided on the outer surface of the valve plate 15. The valve plate 15 is attached to the inner wall of the air intake chamber 12 through the sealing film, so that the valve plate 15 can slide along the inner wall of the air intake chamber 12 and ensure that the valve plate 15 is sealed during the sliding process.

[0042] Specifically, the valve plate 15 adds a dimension to the air pressure regulation of the air pressure chamber 9, which can adjust the air pressure of different areas according to the needs of different parts of the finger, and promote local blood circulation in the finger in a more targeted manner.

[0043] See Figure 3 The side wall of the bent plate 3 has a movable slot 17 that communicates with the air intake chamber 12. A toggle rod 18 is slidably installed inside the movable slot 17. One end of the toggle rod 18 extends into the air intake chamber 12 and is connected to the valve plate 15.

[0044] Specifically, by moving the lever 18, the valve plate 15 can slide within the air intake chamber 12, thereby adjusting the position of the valve plate 15 and thus adjusting the air pressure distribution within the air pressure chamber 9. The design of the movable slot 17 and the lever 18 allows medical staff to easily operate the valve plate 15, adjusting the air pressure distribution in the air pressure chamber 9 without the need for complex tools. This improves the convenience and efficiency of operation and helps to adjust the treatment plan in a timely manner according to the patient's condition.

[0045] See Figure 3 and Figure 6 An extension plate 16 is provided on the side wall of the valve plate 15. The curvature of the extension plate 16 is the same as that of the movable slot 17, and the extension plate 16 is attached to the port of the movable slot 17.

[0046] Specifically, the extension plate 16 serves two purposes: firstly, it acts as a seal to prevent gas leakage from the connection between the movable slot 17 and the valve plate 15; secondly, it allows the valve plate 15 to slide more smoothly within the movable slot 17, ensuring the stability of the valve plate 15 during movement. The extension plate 16 enhances the sealing of the device, ensuring the accuracy and stability of air pressure regulation, preventing air pressure regulation failure due to gas leakage, and improving the smoothness of the valve plate 15's sliding, extending the service life of the device, and improving the overall performance of the clamping plate.

[0047] See Figure 1 The fixing strap includes,

[0048] The first strap 4 is connected at one end to the outer surface of the bottom plate 1, and its outer surface is provided with a Velcro surface.

[0049] The second strap 5 has one end connected to the outer surface of the bottom plate 1, and its outer surface is provided with a hook and loop surface that is bonded to the hook and loop fabric.

[0050] Specifically, in use, the first strap 4 and the second strap 5 are wrapped around the finger, and the finger clip is securely fixed to the finger by the adhesion between the hook and loop sides of the Velcro. The Velcro fixation method is simple and convenient to operate. Patients or medical staff can easily adjust the tightness of the straps to accommodate different finger sizes and patient comfort needs, while ensuring the finger clip is firmly fixed to the finger and preventing it from loosening and affecting the treatment effect.

[0051] See Figure 1 Both the lower panel 1 and the upper panel 2 have pads 7 installed on their inner walls. The pads 7 are made of sponge.

[0052] Specifically, sponge pads 7 are installed on the inner walls of the lower panel 1 and the upper panel 2 to provide soft support for the fingers and reduce pressure.

[0053] See Figure 1 Ventilation holes 6 are provided on both the lower panel 1 and the upper panel 2, and there are multiple ventilation holes 6.

[0054] Specifically, multiple ventilation holes are provided on the splint to promote air circulation and keep the skin of the fingers breathable.

[0055] Working principle: The finger clamp is composed of a lower panel 1 and an upper panel 2 connected by a bending plate 3. It is long and arc-shaped to fit the shape of the finger and wraps the finger inside. The fixing straps include a first strap 4 and a second strap 5, which are fastened around the finger with Velcro to firmly fix the finger clamp. The lower panel 1 and the upper panel 2 are equipped with air pressure chambers 9. Through the air inlet 13 on the side wall of the bending plate 3, the valve 14 controls the air intake or exhaust. The gas enters the air pressure chamber 9 through the air inlet 12. The air pressure chamber 9 is connected to the soft air bag 11 through the air outlet 10. When the air pressure changes, the soft air bag 11 expands or contracts accordingly, applying or changing the pressure on the finger. At the same time, by moving the lever 18 in the movable slot 17 of the bending plate 3, the valve plate 15 is moved to slide in the air inlet 12 to adjust the volume of the left and right chambers of the air pressure chamber 9, so as to achieve precise adjustment of the air pressure in different parts.

[0056] The extension plate 16 on the side wall of the valve plate 15 fits into the movable slot 17 to ensure smooth sliding and prevent gas leakage. The flexible membrane 8 installed on the opposite side of the lower panel 1 and the upper panel 2, which connects to the air pressure chamber 9, can expand or contract due to changes in air pressure in the air pressure chamber 9 to assist in regulating air pressure.

[0057] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
