Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic instruments, in particular to an orthopedic splint. Background Art

[0002] Orthopedics is a common department in major hospitals, and fractures are also common injuries. After a fracture occurs, the fracture site needs to be restored and fixed to prevent secondary injury. The wound surface will slowly repair after the combination to achieve the purpose of healing the fracture, so a splint is needed to fix the fracture part;

[0003] However, during the use of the existing splint, the splint is tied on the fracture position. The most common practice is to use the splint and bandage to tie it up to achieve the fixation effect. However, since it is not ventilated, when encountering hot weather, the patient sweats, and the sweat can easily cause skin inflammation at the injured part. This will cause secondary injuries to the patient, which not only affects the efficiency of recovery, but also brings troubles to medical staff. For this reason, we propose an orthopedic splint to solve the above problems. Utility Model Content

[0026] Through the above technical scheme, the hand crank 2 can be used to easily drive the forward and reverse threaded rods 3 to rotate. Since the threads on the surfaces of the forward and reverse threaded rods 3 and the threads in the inner cavity of the threaded sleeve 10 are threadedly connected, when the forward and reverse threaded rods 3 rotate, the threaded sleeve 10 is driven to move, and the movement of the threaded sleeve 10 drives the support block 13 to move, and the movement of the slide plate 12 drives the support block 13 to move, and the movement of the support block 13 drives the sliding plate 6 to move, and the movement of the sliding plate 6 drives the C-type splint 7 to move, and the movement of the C-type splint 7 fixes the fracture site of the patient, which is convenient for better recovery of the fracture site. Through the fan 17, it is easy to drive the suction pipe 16 to absorb gas, and discharge it to the surface of the C-type splint 7 through the cooperation of the exhaust pipe 8, and through the cooperation of the through holes on the surface of the C-type splint 7, the air flow on the inner surface of the C-type splint 7 is accelerated, thereby achieving the ventilation effect of the splint.

[0027] Specifically, a through hole is provided on the surface of the C-shaped clamping plate 7, a bearing is fixedly connected to the right side of the inner cavity of the fixed shell 1, and the right side of the positive and negative threaded rod 3 is rotatably connected to the inner cavity of the bearing, and the two ends of the left center of the fixed shell 1 and the two sides of the positive and negative threaded rod 3 are fixedly connected to the limit block 5, and the surface of the positive and negative threaded rod 3 is provided with a plug hole, and the plug hole and the inner cavity of the limit block 5 are plugged with a pin rod 4, and the inner cavity of the fixed shell 1 is provided with a slide groove 11 on both sides, and one side of the slide plate 12 is slidably connected to the inner cavity of the slide groove 11, and the bottom of the inner cavity of the shell 9 is fixedly connected to the inner cavity of the slide groove 11. A filter plate 14 is fixedly connected to the left side, and an air inlet 15 is provided at the bottom of the left side of the inner cavity of the shell 9. When the fan 17 is working, its own negative pressure generates suction, and the air enters the inner cavity of the shell 9 through the air inlet 15 due to the influence of the suction. The absorbed gas is filtered through the filter plate 14, and debris in the air, such as lint, is effectively removed to prevent debris from entering the interior of the fan 17 and causing damage to its internal parts, thereby improving the use efficiency of the fan 17 and solving the troubles of the staff.

[0028] The working principle of the utility model is as follows: first, the user places the fractured part of the patient's leg on the surface of the fixing shell 1 on the inner side of the C-shaped splint 7; secondly, the user holds the hand crank 2 and drives the positive and negative threaded rod 3 to rotate through the hand crank 2; since the threads on the surfaces of the positive and negative threaded rod 3 and the threads in the inner cavity of the threaded sleeve 10 are threadedly connected, when the positive and negative threaded rod 3 rotates, the threaded sleeve 10 is driven to move; the movement of the threaded sleeve 10 drives the support block 13 to move; the movement of the slide plate 12 drives the support block 13 to move; the movement of the support block 13 drives the sliding plate 6 to move; the movement of the sliding plate 6 drives the C-shaped splint 7 to move; the movement of the C-shaped splint 7 fixes the fractured part of the patient, which is convenient for better rehabilitation of the fractured part. When encountering hot weather, When the patient sweats and the injured part feels uncomfortable, the user starts the fan 17 through the external controller, and the fan 17 drives the suction pipe 16 to absorb air. Due to the suction force, the air enters the inner cavity of the shell 9 through the air inlet 15, and passes through the filter plate 14 to filter the absorbed gas, effectively remove the debris in the air, such as lint, etc., to prevent the debris from entering the interior of the fan 17 and causing damage to its internal parts, thereby improving the use efficiency of the fan 17 and solving the troubles of the staff. After the air is filtered by the filter plate 14, it is discharged to the surface of the C-type splint 7 through the cooperation of the air outlet pipe 8. Through the cooperation of the through holes on the surface of the C-type splint 7, the air flow on the inner surface of the C-type splint 7 is accelerated, thereby achieving the ventilation effect of the splint.
