Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a child's upper limb fixation device. Background Art
[0002] During the growth process of children, due to their immature bone development and their lively and active nature, upper limb fractures become a relatively common health problem. Children's bone structure is relatively fragile, with low bone density and sparse trabeculae, which makes them more susceptible to upper limb fractures when faced with external force impacts, such as falls, collisions, or falls from heights. For the treatment of upper limb fractures in children, fixing the fracture site is a crucial step. The main purpose of fixation is to maintain the reduction of the fracture and prevent the fracture ends from being displaced again during the healing process, thereby ensuring that the fracture can heal as expected. At the same time, fixation can also create conditions for early movement of muscles and joints, preventing complications such as muscle atrophy and joint stiffness.
[0003] At present, there are corresponding upper limb fracture fixation devices for fixing children's upper limb fractures. When fixing, the arm is directly fixed over a large area, which facilitates fixation to a certain extent. However, when fixing a certain part, the entire arm needs to be fixed, and the two sides of the fracture site cannot be fixed specifically. Fixing the entire arm over a large area for a long time will cause atrophy of the arm muscles, or may also cause the risk of pressure sores in non-fracture sites. There are still defects to a certain extent.
[0004] Therefore, a children's upper limb fixation device is needed to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION
[0019] Example 1
[0020] The utility model discloses a child upper limb fixation device, comprising: a forearm fixation plate 1, an upper arm fixation plate 2, and a reinforcement mechanism 3; the upper arm fixation plate 2 is rotatably mounted on one end of the forearm fixation plate 1 via a rotating shaft 11, and a slide groove 13 is provided on both sides of the upper ends of the forearm fixation plate 1 and the upper arm fixation plate 2, and the reinforcement mechanism 3 is slidably mounted on the slide groove 13; the forearm and upper arm parts of the patient can be fixed respectively by the forearm fixation plate 1 and the upper arm fixation plate 2, and the reinforcement mechanism 3 is slidably mounted on the forearm fixation plate 1 and the upper arm fixation plate 2, and the fracture part of the patient can be slidably reinforced by the reinforcement mechanism 3, and only the two sides of the fracture part need to be fixed in a targeted manner. Compared with traditional devices, different parts can be reinforced;
[0021] Specifically, the reinforcement mechanism 3 includes: a support plate 31, a fixing head 32 and a snap mechanism 34, the support plate 31 is slidably installed on the slide groove 13, the fixing head 32 is movably installed in the middle of the upper end of the support plate 31, and a pressing head 33 is fixedly installed on the upper end of the fixing head 32, the fixing head 32 passes through the inner side of the support plate 31 and a contact plate 35 is fixedly installed at the end, the contact plate 35 is an arc structure, and a plurality of cushion layers 351 are arranged in a circular array on the inner surface; in order to ensure that the contact plate 35 reduces the pressure on the patient's skin when contacting the patient's skin, a corresponding cushion layer 351 can be added to the contact surface of the contact plate 35 to increase comfort, and at the same time, it can reduce pressure and protect the skin of the patient's fracture site. The cushion layer 351 can be made of materials such as silicone rubber; the fixing head 32 between the contact plate 35 and the support plate 31 is sleeved A spring 322 is provided; a plurality of sockets 321 are provided in a linear array on the side wall of the fixing head 32, and the snap mechanism 34 is fixedly installed on the support plate 31 corresponding to the position of the sockets 321; the upper and lower positions of the contact plate 35 are controlled by controlling the position of the snap mechanism 34 on the socket 321 to achieve different fixing needs; when in use, the fixing head 32 is pressed, and the spring 322 is compressed, and then the snap mechanism 34 is used to clamp it, that is, the snap mechanism 34 is clamped into the socket 321 to form a fixing effect; after use, the snap mechanism 34 is pulled out and restored to its original position under the elastic force of the spring 322, and the fracture point can be further fixed by the provided reinforcement mechanism 3 so that the fracture point will no longer be relatively dislocated; on the one hand, it can reduce the patient's pain, and on the other hand, it can reduce the damage of the broken bone to the surrounding tissues.
[0022] Example 2
[0023] Based on the snap mechanism 34 of Example 1, in this embodiment, the snap mechanism 34 includes a fixed block 341 and an insertion strip 342; the fixed block 341 is a hollow structure and is fixedly installed on the outer wall of the support plate 31, and a spring 322 is fixedly installed inside the fixed block 341, and the end of the spring 322 is fixedly installed with the insertion strip 342, and the insertion strip 342 can be inserted into the interior of the fixed block 341 and a clamping block 343 is fixedly installed on the insertion strip 342; when using the snap mechanism 34, by pulling the clamping block 343, the insertion strip 342 is moved along the inside of the fixed block 341, so that the insertion strip 342 and the socket 321 lose the fixing effect on each other, and at this time the fixing head 32 returns to its original position, that is, it no longer forms a fixing effect.
[0024] In addition, in this embodiment, based on what is described in Example 1, square grooves 12 are provided on both sides of the forearm fixing plate 1, and telescopic rods 21 are rotatably installed on both sides of the upper arm fixing plate 2 close to one end of the forearm fixing plate 1, and the other end of the telescopic rod 21 is rotatably fixed on the direction groove by a bolt 22; the angle between the forearm fixing plate 1 and the upper arm fixing plate 2 can be adjusted by the mutual cooperation of the bolt 22 and the telescopic rod 21. When a large angle adjustment is required, that is, when the angle between the upper arm fixing plate 2 and the forearm fixing plate 1 is greater than 90 degrees, the bolt 22 is loosened, and then the upper arm fixing plate 2 is directly rotated. The fixing plate 2 is adjusted to the corresponding angle, and then the bolts 22 are tightened to achieve fixation; the angle can be adjusted to meet different fixation needs. At the same time, a reinforcement mechanism 3 is provided on the upper arm fixing plate 2 and the forearm fixing plate 1, and the reinforcement mechanism 3 can slide to adjust the fixation of different fracture sites; the reinforcement mechanism 3 slides with a certain damping when adjusting. At the same time, when fixing the patient's arm, due to the existence of friction between the arm and the contact plate 35, it is difficult for the reinforcement mechanism 3 to move after the fracture site is fixed by the reinforcement mechanism 3, which can form a relatively stable effect.
[0025] The principle of use of the present invention is as follows: before use, it should be determined whether the patient's fracture site is located in the upper arm, forearm or elbow; after determination, when using, if the fracture site is the upper arm or forearm, the reinforcement mechanism 3 is slid to the corresponding position according to the corresponding site, and then it is put on the patient's arm and the fracture site is further fixed by using the reinforcement mechanism 3; at the same time, if there is a demand for the fixed angle, the angle can be adjusted accordingly, and the adjustment method is as described in Example 2 and will not be explained in detail here; if it is an elbow fracture, first loosen the bolt 22, then rotate the upper arm fixing plate 2 and the forearm fixing plate 1 to a colinear position and then tighten the bolt 22, then put the arm in, and then fix the forearm and upper arm at the same time by the reinforcement mechanism 3 to complete the fixation; after use, loosen the reinforcement mechanism 3 and take out the arm.
[0026] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all details in detail, nor do they limit the present invention to only the specific implementation methods described.
