Description

Technical Field

[0001] This utility model belongs to the field of support structure technology, and in particular relates to an easily adjustable orthopedic nursing frame support structure. Background Technology

[0002] In orthopedic clinical nursing, for patients with lower limb fractures, joint injuries, etc., nursing frames are often used to support and fix their legs in order to promote wound healing, reduce pain and prevent secondary injury.

[0003] However, during the process of supporting the patient's lower limbs with a nursing frame, the different body shapes and lengths of the lower limbs of different patients, as well as the different injury conditions of the patients, lead to different support requirements for the nursing frame. If a single adjustable support structure is used for nursing support, the leg rest will not be able to effectively support the lower limbs, which will cause discomfort to the patient and may even cause secondary injury in severe cases. Therefore, an easily adjustable orthopedic nursing frame support structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable orthopedic nursing frame support structure. By setting an adjustment component, specifically a lateral adjustment piece, the distance between the two sets of leg supports and the seat can be adjusted to accommodate patients of different heights. When adjusting the height of the leg supports, pressing the front end of the lever disengages the pin from the pin hole, allowing the sleeve to slide up and down to adjust the height of the lower leg support. After releasing the lever, a spring causes the lever to reset, and the pin re-inserts into the corresponding pin hole for fixation. Combined with the initial height difference between the thigh and lower leg supports, the leg flexion and extension angles can be flexibly adjusted. This solves the problem that due to differences in body shape and lower limb length among patients, as well as variations in patient injury conditions, leg supports often fail to effectively support the lower limbs, leading to discomfort and potentially secondary injuries.

[0027] The lateral moving component includes an opening 213 inside the vehicle body 111. Two sliding grooves 214 are formed at the bottom of the vehicle body 111. The outer wall of the moving seat 212 is slidably connected to the inner wall of the opening 213. Two sliders 215 are fixedly connected to the top of the bottom of the moving seat 212. The outer surfaces of the two sliders 215 are slidably connected to the inside of the sliding grooves 214. The sliding grooves 214 are located on the front and rear sides of the opening 213. The sliding grooves 214 and the sliders 215 are used to limit and guide the movement trajectory of the moving seat 212. The moving seat 212 passes through the opening 213 and extends to the top and bottom. A threaded rod 216 is threadedly connected to the center of the moving seat 212. 16 extends through the opening 213 to the right side. The outer surface of the threaded rod 216 is rotatably connected to the inner edge of the vehicle body 111. A crank handle 211 is provided on the right side of the vehicle body 111. The inside of the crank handle 211 is fixedly connected to the outer surface of the threaded rod 216. The outer surface of the crank handle 211 is provided with anti-slip texture. Two bellows 217 are sleeved on the outer surface of the threaded rod 216. The corresponding sides of the two bellows 217 are fixedly connected to the left and right sides of the movable seat 212, respectively. The sides of the two bellows 217 away from the movable seat 212 are fixedly connected to the left and right sides of the inner wall of the opening 213, respectively. The bellows 217 are used to protect the connection between the threaded rod 216 and the movable seat 212.

[0028] One specific application of this embodiment is as follows: In use, the device is first moved to a suitable position and locked using the self-locking casters 112. The patient sits on the seat 114 and adjusts it according to the patient's body shape and rehabilitation needs. When adjusting the lateral spacing, the operator turns the crank handle 211, which drives the threaded rod 216 to rotate. Since the movable seat 212 is threadedly connected to the threaded rod 216, and the slider 215 slides along the slide groove 214, the movable seat 212 will move laterally along the opening 213, thereby adjusting the spacing between the two sets of leg supports and the seat 114 to fit the patient's leg length. The corrugated pipe 217 provides dust protection at the connection between the threaded rod 216 and the movable seat 212.

[0029] When adjusting the height, press the upper end of lever 2112. Lever 2112 rotates around the hinge seat, compressing spring 2115 and simultaneously causing pin 2116 to disengage from pin hole 2117. At this time, the sleeve 218 can be slid up and down to adjust the height of calf support 210 and thigh support 2111. After adjusting to the appropriate position, release lever 2112. Spring 2115 returns to its original position, causing lever 2112 to rotate. Pin 2116 re-inserts into the corresponding pin hole 2117 to fix the height. Lever 2112 slides along limit rod 2114 through slot 2113 to ensure stable movement trajectory of lever 2112.

[0030] The thigh support 2111 is initially higher than the calf support 210, forming a natural flexion and extension angle. The support rod 222 can slide along the support tube 221 and compress or stretch the second spring 223. In conjunction with the damping pivot, it can adaptively adjust according to the angle of the patient's leg placement, so that the thigh support 2111 conforms to the curve of the thigh. When the patient's leg is placed on the calf support 210 or during slight movement, the calf support 210 compresses the third spring 226 through the connecting rod 227. The damping rod 225 suppresses the rebound potential energy of the third spring 226, playing a buffering and shock absorption role and reducing the discomfort caused by impact.
