Description

Technical Field

[0001] This utility model relates to the field of medical protective gear technology, specifically to a modular distal radioulnar joint supination fixation brace. Background Technology

[0002] The function of the distal radioulnar joint is to stabilize the rotation of the radius distal to the ulna. Its stability is maintained by the distal radioulnar palmar ligament, the distal radioulnar dorsal ligament, and the triangular fibrocartilaginous disc. When there is a direct or indirect force causing a rupture of the distal radioulnar palmar or dorsal ligament, or accompanied by a rupture of the triangular fibrocartilaginous disc, the ulnar process may dislocate dorsally or palmarly.

[0003] Currently, the conservative treatment for distal radioulnar joint dislocation (wrist dislocation) is mainly through manual reduction and plaster cast immobilization. Utility Model Content

[0004] Therefore, this utility model provides a modular radioulnar joint supination fixation brace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular distal radioulnar joint supination fixation brace, the fixation brace comprising an upper fixation brace covering the inner side of the upper arm from the patient's distal radioulnar joint and a lower fixation brace covering the outer side of the upper arm from the patient's distal radioulnar joint, the inner layer of the lower fixation brace near the elbow joint having a detachable positioning structure, and the outer sides of the upper and lower fixation braces having a fixing structure.

[0006] Furthermore, the fixed lower guard has an opening on its inner side, which is located on one side of the positioning structure, and the size of the opening is such that it can pass through the positioning structure.

[0007] Furthermore, the positioning structure includes a soft cotton cloth and an aluminum plate, with the aluminum plate disposed in the inner layer of the soft cotton cloth.

[0008] Furthermore, the positioning structure also includes a flexible pressure sensor and a display screen mounted on the fixed upper guard. One side of the flexible pressure sensor is bonded to one side of the soft cotton cloth, and the pressure applied by the deformation of the aluminum plate to the flexible pressure sensor is transmitted to the display screen.

[0009] Furthermore, the fixing structure includes multiple elastic straps disposed on one side of the outer wall of the lower protective garment. The elastic straps are provided with Velcro, which includes a hook and loop side and an adhesive side. The hook and loop side is disposed on the inner side of the elastic straps, and the adhesive side is disposed on the outer bottom end of the lower protective garment. Both the upper and lower protective garments are provided with positioning buckles corresponding to the elastic straps.

[0010] This utility model has the following advantages:

[0011] In actual use, the size of the upper and lower fixation braces is made according to the patient's arm length and other body data. The patient's elbow is aligned with the bend of the upper and lower fixation braces, and pressure can be applied in different directions according to the fracture type. One end of the upper and lower fixation braces on the same side can cover the patient's distal radioulnar joint. The upper fixation brace is on top and the lower fixation brace is on the bottom. The elastic bandage is passed through the positioning buckles on the upper and lower fixation braces in sequence, and the hook and loop fasteners are attached together to achieve fixation of the wrist joint itself after the wrist dislocation is reduced.

[0012] If the patient's range of motion is too large, causing pressure on the aluminum plate in the positioning structure and resulting in deformation, the wireless gateway can convert the signal from the flexible pressure sensor into a digital signal. The display shows the real-time pressure value and emits an audible alert, prompting the patient to reset the position. The pressure value is then sent to a remote mobile device for remote monitoring and recording. This invention is characterized by its ease of use, secure fixation, and good reduction effect. Clinically, it is used for the conservative treatment of distal radioulnar joint dislocations and distal radius fractures. Attached Figure Description

The inner layer of the lower fixation brace 2 near the elbow joint is provided with a detachable positioning structure 3, and the outer sides of the upper fixation brace 1 and the lower fixation brace 2 are provided with fixation structures.

[0021] As a preferred technical solution of this application, the inner side of the fixed lower guard 2 is provided with an opening 4, the opening 4 is located on one side of the positioning structure 3, and the size of the opening 4 is such that it can pass through the positioning structure 3.

[0022] As a preferred technical solution of this application, the positioning structure 3 includes a soft cotton cloth 5 and an aluminum plate 6, wherein the aluminum plate 6 is disposed in the inner layer of the soft cotton cloth 5.

[0023] As a preferred technical solution of this application, the positioning structure 3 further includes a flexible pressure sensor 7 and a display screen 8 disposed on the fixed upper guard 1. One side of the flexible pressure sensor 7 is bonded to one side of the soft cotton cloth 5, and the pressure applied by the deformation of the aluminum plate 6 to the flexible pressure sensor 7 is transmitted to the display screen 8.

[0024] The flexible pressure sensor 7 in this embodiment is a piezoelectric pressure sensor. The dielectric layer material can be one of carbon nanotubes, graphene, nanowires, organic polymers, or ion gels. In this embodiment, carbon nanotubes are selected. The piezoelectric pressure sensor in this embodiment can be wirelessly networked to remotely connect with mobile devices such as mobile phones and tablets, which facilitates data recording and monitoring.

[0025] As a preferred technical solution of this application, the fixing structure includes multiple elastic straps 9 disposed on one side of the outer wall of the fixed lower protective garment 2. The elastic straps 9 are provided with hook and loop fasteners, which include a hook and loop loop surface 11 and a hook and loop loop fastener surface 12. The hook and loop loop surface 11 is disposed on the inner side of the elastic straps 9, and the hook and loop loop fastener surface 12 is disposed on the outer bottom end of the fixed lower protective garment 2. The fixed upper protective garment 1 and the fixed lower protective garment 2 are both provided with positioning buckles 10 corresponding to the elastic straps.

[0026] In actual use, the sizes of the upper and lower braces 1 and 2 are made according to the patient's arm length and other body data. The patient's elbow is aligned with the bend of the upper and lower braces 1 and 2 (pressure can be applied in different directions depending on the fracture type). One end of the upper and lower braces 1 and 2 on the same side can cover the patient's distal radioulnar joint. The upper brace 1 is on top and the lower brace 2 is on the bottom. The elastic bandage 9 is passed through the positioning buckles 10 on the upper and lower braces 1 and 2 in sequence, and the hook and loop fasteners 11 and 12 are attached together to achieve the purpose of wrist joint supination fixation and immobilization.

[0027] If the patient's range of motion is too large, causing pressure on the aluminum plate 6 in the positioning structure 3, the aluminum plate 6 will deform. The wireless gateway can convert the signal from the flexible pressure sensor into a digital signal, display the real-time pressure value on the screen, and issue a prompt sound to alert the patient to reset the position. The pressure value is then sent to a remote mobile device for remote monitoring and recording. This invention is convenient to use, provides secure fixation, and achieves good reduction results. Clinically, it is used for the conservative treatment of distal radioulnar joint dislocation and distal radius fractures.

[0028] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
