Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic auxiliary appliances, in particular to an auxiliary positioning splint for arm fractures. Background Art

[0002] As we all know, fracture refers to the complete or partial break of the continuity of bone structure. This disease is more common in children and the elderly, and sometimes occurs in young and middle-aged people. Patients often have a single fracture, and a few have multiple fractures. With timely and appropriate treatment, most patients can recover their original functions. A few patients may have sequelae of varying degrees if they are not treated in time or errors occur during treatment.

[0003] The forearm is the part between the elbow and wrist of the forelimb, the front part of the hand joint, and the bones on the forearm include the radius and ulna. Since the forearm is a relatively long cantilever physical structure, children and the elderly are prone to fractures of the radius and ulna when carrying heavy objects or in winter when bone density is low; after a fracture, it is generally necessary to restore the displaced fracture ends to a normal or nearly normal anatomical relationship, reconstruct the support function of the bone, and then maintain the fracture in the reduced position so that it can heal firmly under good alignment, which is the key to fracture healing. The existing technology generally uses plaster materials for fixation, that is, soaking the plaster roll in warm water, squeezing out the water from the plaster roll, applying it to the required position of the plaster, and shaping it at the same time, wrapping it with a bandage, and holding the tubular plaster, reducing activity before the tubular plaster hardens, and exposing the finger tips to observe blood circulation. After the tubular plaster solidifies, an X-ray examination is performed to determine whether ectopicity occurs; the tubular plaster Although plaster-assisted positioning can firmly position the fracture site, it is heavy, and the tubular plaster will shrink during the hardening process. The interior of the tubular plaster structure is very airtight and has no air permeability, which makes the patient's arm skin breathable. After long-term use, they will often sweat, and because of the itchy skin, the patient's comfort is poor; the fracture rehabilitation process generally lasts for several months, during which the user also needs to use a shoulder strap to hang the arm and the tubular plaster on the chest, and the tubular plaster is heavy, which causes a heavy burden on the patient's shoulders and neck, and the comfort is also poor; and after the fracture is healed, the tubular plaster layer needs to be cut and removed with a cutting machine, and the patient's skin may be cut during the cutting process, causing secondary injury to the patient. Therefore, the above-mentioned many shortcomings cannot meet the actual use needs of medical staff and patients, so the above-mentioned defects are very obvious. For this reason, we propose an auxiliary positioning splint for arm fractures to solve the above-mentioned problems. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide an auxiliary positioning splint for arm fractures.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An auxiliary positioning splint for arm fractures comprises a deformable sleeve, the inner cavity of the sleeve is cylindrical and adapted to the surface of a human forearm, an opening is arranged on the peripheral side of the sleeve, the sleeve is opened through the opening and is fitted on the human forearm, a hook piece is arranged at one end of the sleeve and opposite to between the thumb and index finger of the human body, a strap is arranged on the sleeve and on one side of the opening, the strap is detachably connected to the other side of the opening through a locking piece, and the inner cavity of the sleeve is tightly fitted on the surface of the human forearm.

[0007] Preferably, a plurality of limiting rings are provided on the surface of the sleeve and along the length direction of the sleeve, and the binding strap can selectively pass through different limiting rings and be fixed to the surface of the sleeve by Velcro.

[0008] Preferably, the sleeve body is made of a plastic flexible plate, and the surface of the sleeve body is covered with a soft shell.

[0009] Preferably, a plurality of air holes are provided on the surface of the sleeve.

[0012] Due to the adoption of the above scheme, the utility model has the following obvious advantages and beneficial effects compared with the prior art:

[0013] 1. The sleeve is made of a lightweight plastic flexible board and is tightly wrapped around the surface of the human forearm through a strap, so the overall weight is light. The plastic flexible board also has a certain structural strength. The hook is located at the base of the thumb and index finger of the human body, so the fracture of the patient can be effectively located and fixed. Even if the user uses a shoulder strap to hang the sleeve and the arm in front of the chest, the burden on the user's shoulder and neck is small, which improves the user's comfort;

[0014] 2. The sleeve body is provided with a number of ventilation holes, the surrounding side of the sleeve body is provided with openings, and the surface of the sleeve body is covered with a soft shell, so the overall air permeability is good and it is not airtight. The soft shell exerts less pressure on the patient's skin, effectively preventing sweating on the arm after long-term use, and the patient feels more comfortable when using it;

[0015] 3. When the patient's fracture has recovered, the medical staff or the patient only needs to open the locking piece on the strap to remove the sleeve through the opening, which effectively prevents the patient from being injured again during the removal process and improves the safety of use. Therefore, it has multiple practical functions, which greatly meets the actual use needs of medical staff and patients. It has a simple structure, is easy to operate, and is very practical.
