Description

Technical Field

[0001] The utility model relates to the field of fracture fixation instruments, in particular to an external fixation device for human forearm fractures. Background Art

[0002] For patients with upper limb fractures, a specialized forearm sling is often used to suspend the affected limb during treatment to promote venous return, facilitate the resolution of hematomas, and facilitate fracture healing. Forearm slings are typically made of textile material in a pouch-like shape and are placed around the neck with a webbing strap. When used, the elbow is generally flexed 90 degrees and then placed in the middle position on the chest for suspension. However, commonly used forearm slings only wrap the forearm around the chest and cannot guarantee a permanent hold on the forearm. They often shift with movement, especially in children, who are highly active. Their constant movement can cause the sling to detach from the forearm or prevent the elbow from being flexed 90 degrees, adversely affecting fracture fixation treatment. Summary of the Invention

[0003] The utility model aims to solve the deficiencies of the prior art and provides an external fixation device for a human forearm fracture.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] Disclosed is an external fixation device for a human forearm fracture, comprising a cloth bag, an internal fixation sleeve, and an adjustable sling. The cloth bag is U-shaped, and the front and rear ends of the adjustable sling are each connected to a connecting buckle. The top of the cloth bag is open, and both side walls of the front end of the top opening of the cloth bag are connected to the front sling, and both side walls of the rear end of the top opening of the cloth bag are connected to the rear sling. The adjustable sling is respectively connected to the front sling and the rear end sling through the connecting buckles, and the internal fixation sleeve is adhered to the bottom of the cloth bag. The internal fixation sleeve can be unfolded into a rectangle or rolled into a sleeve shape.

[0006] The inner surface of the inner fixing sleeve is wrapped with a plurality of breathable memory strips along the length direction.

[0007] One side edge of the inner fixing sleeve is connected with a plurality of Velcro hook strips, and the other side outer surface edge of the inner fixing sleeve is connected with a Velcro fleece block.

[0008] A Velcro hook surface block is connected to the middle portion of the outer surface of the inner fixing sleeve, and the bottom of the inner surface of the cloth bag is a fleece surface corresponding to the Velcro hook surface block.

[0009] The adjustable sling is sleeved with a protective cover, the outer surface of which is a cotton surface.

[0010] The adjustable sling is a double-layer belt-shaped fabric, and the length of the adjustable sling is adjusted by a connecting buckle at one end.

[0011] The connecting buckle is a "sun" shaped connecting buckle.

[0012] The beneficial effects of the utility model are as follows: the utility model has a compact structure, the internal fixation sleeve and the cloth bag are detachably connected, the cloth bag is easy to disassemble and clean, the internal fixation sleeve is tightly wrapped around the forearm, and the internal fixation sleeve is prevented from moving randomly on the forearm, ensuring that the elbow joint is flexed 90 degrees, and then the fracture site is placed in front of the chest for suspension, thereby ensuring the fixation of the forearm fracture.

[0017] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figure 1 As shown, an external fixation device for a human forearm fracture comprises a cloth bag 5, an internal fixing sleeve 6 and an adjustable sling 1. The cloth bag 5 is U-shaped, and the front and rear ends of the adjustable sling 1 are each connected to a connecting buckle 3. The top of the cloth bag 5 is open, and the two side walls of the front end of the top opening of the cloth bag 5 are connected to the front sling 4, and the two side walls of the rear end of the top opening of the cloth bag 5 are connected to the rear end sling 10. The adjustable sling 1 is respectively connected to the front sling 4 and the rear end sling 10 through the connecting buckle 3. The internal fixing sleeve 6 is adhered to the bottom of the cloth bag 5, and the internal fixing sleeve 6 can be unfolded into a rectangle or rolled into a sleeve shape.

[0020] The inner surface of the inner fixing sleeve 6 is wrapped with a plurality of breathable memory strips 7 along the length direction.

[0021] One side edge of the inner fixing sleeve 6 is connected to a plurality of Velcro hook strips 9 , and the other side outer surface edge of the inner fixing sleeve 6 is connected to a Velcro fleece block 8 .

[0022] A Velcro hook surface block 11 is connected to the middle portion of the outer surface of the inner fixing sleeve 6 , and the bottom of the inner surface of the cloth bag 5 is a fleece surface corresponding to the Velcro hook surface block 11 .

[0023] The adjustable sling 1 is sleeved with a protective cover 2, and the outer surface of the protective cover 2 is a cotton surface to prevent the adjustable sling 1 from rubbing the neck.

[0024] The adjustable sling 1 is a double-layered belt-shaped fabric, and the length of the adjustable sling 1 is adjusted by a connecting buckle 3 at one end.

[0025] The connecting buckle 3 is a "sun" shaped connecting buckle.

[0026] When the present invention is used, the internal fixation sleeve 6 is first unfolded, the fractured forearm is placed on the internal fixation sleeve 6, and then the internal fixation sleeve 6 is rolled up on the forearm, and the forearm is tightly wrapped by sticking the Velcro hook noodles 9 on the Velcro fleece block 8 and squeezing the breathable memory strip 7 on the plaster surface of the forearm. Then the internal fixation sleeve 6 is placed on the bottom of the cloth bag 5, and the Velcro hook block 11 is stuck on the fleece surface at the bottom of the inner surface of the cloth bag 5, and the internal fixation sleeve 6 is tightly connected to the cloth bag 5. Then the adjustable sling 1 is put on the neck, the length of the adjustable sling 1 is adjusted according to comfort, and the forearm is suspended in front of the chest to prevent the forearm from easily falling off from the cloth bag 5.
