Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to an adjustable integrated splint for proximal humeral fractures in adults. Background Technique

[0002] Proximal humeral fracture is a common type of fracture. Most domestic and foreign literatures believe that its incidence rate is 4%-5%. Among them, 80%-85% are non-displaced or mildly displaced fractures, and 15%-20% are displaced fractures, and most of them require surgical treatment. Proximal humeral fractures can occur at any age, but are common in elderly patients. For patients treated conservatively, traditional Chinese medicine uses supra-articular splints for external fixation, and Western medicine uses plaster for external fixation. Plaster external fixation has high requirements for shaping, poor compression effect on fractures, cannot be disassembled at any time to observe the skin, and is not convenient for applying traditional Chinese medicine externally. The supra-shoulder joint splint is composed of four separate wooden boards. If the binding is too tight, it is easy to cause local blood circulation disorders and skin breakdown. If the binding is too loose, it cannot effectively splint the fracture, resulting in fracture displacement again. Due to the specific anatomical structure of the shoulder joint, the splint is often not firmly fixed during fixation. Therefore, it is basically very difficult for the proximal humeral fixation braces on the market to effectively fix the fracture. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to provide an adjustable integrated splint for proximal humeral fractures in adults to solve the above problems.

[0004] The technical solution of the utility model to solve the above technical problems is as follows: an adjustable integrated splint for proximal humeral fractures in adults, comprising: a splint mechanism, a plurality of buckles, a three-way buckle, a plurality of fixing straps, a connecting strap, a forearm sling and a plurality of figure-eight buckles; the three-way buckle is arranged at one end of the splint mechanism, the plurality of fixing straps pass through the splint mechanism side by side, and the ends are respectively connected to the plurality of buckles, the two ends of the connecting strap are respectively connected to the other end of the splint mechanism and the forearm sling, and the figure-eight buckles are arranged on the fixing straps and the forearm sling. When the buckles and the three-way buckle are both buckled, the splint mechanism and the fixing straps are wound around the patient's upper arm. When the forearm sling is hung on the patient's neck through the figure-eight buckle, the patient's forearm is placed in the forearm sling.
