Description

Technical Field

[0001] The utility model relates to the technical field of fracture braces, in particular to an inflatable radial wrist brace. Background Art

[0002] Distal radius fractures are very common. When patients seek medical treatment, they often present with swelling and deformity of the affected wrist. After X-ray examination, depending on the type of fracture, manual reduction and plaster external fixation are usually performed first. If the reduction is satisfactory after another X-ray, the patient is generally asked to return for a follow-up visit one week later.

[0003] Currently, distal radius fractures are usually fixed on-site with a plaster brace or plastic brace. However, as the swelling of the patient's limb subsides, the plaster will become loose, resulting in loss of reduction. Replacing the plaster may also cause loss of fracture reduction. The brace cannot adjust the palmar flexion angle on its own, and the original plaster needs to be removed and re-fixed with plaster. There is no continuous pressure device or pressure sensing device, so the pressure inside the brace cannot be monitored at any time and the pressure to maintain reduction cannot be maintained for a long time.

[0004] Based on this, an inflatable radial wrist brace is now provided, which can eliminate the disadvantages of existing devices. Utility Model Content

[0005] The purpose of the utility model is to provide an inflatable radial wrist brace to solve the problems in the background art that as the swelling of the patient's limb subsides, the plaster will become loose, resulting in loss of reduction; the fracture reduction may be lost when the plaster is replaced; the brace cannot adjust the palmar flexion angle by itself, and the original plaster needs to be removed and re-fixed with plaster; there is no continuous pressurization device and no pressure sensing device, and the pressure in the brace cannot be monitored at any time to maintain the reduction pressure for a long time.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An inflatable radial wrist brace includes a brace outer shell, wherein one side of the bottom of the brace outer shell is open, a first inflatable pressure regulating mechanism is provided in the brace outer shell, a connecting sleeve is provided at the upper portion of the outer end of the brace outer shell, a second inflatable pressure regulating mechanism is provided in the connecting sleeve, and a fixing mechanism is provided on the outer side of the brace outer shell.

[0008] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0009] In an optional solution, the first inflatable pressure regulating mechanism includes a first airbag, which is located on the inner wall of the brace outer shell. A first inflation hole is provided on the surface of the brace outer shell, and the first inflation hole is connected to the first airbag. A first deflation hole is provided on the brace outer shell on one side of the first inflation hole.

[0010] In an optional solution: the second inflatable pressure regulating mechanism includes a second airbag, the second airbag is located on the inner side wall of the connecting sleeve, a second inflation hole is provided on the connecting sleeve, and the second inflation hole is connected to the second airbag, and a second deflation hole is provided on the connecting sleeve on one side of the second inflation hole.

[0011] In an optional solution, the fixing mechanism includes a first fixing block, which is located on one side of the opening of the brace cover and is provided with a plurality of restraining belts. A plurality of evenly distributed connecting belts are provided on the other side of the opening of the brace cover, and buckles are provided on the connecting belts. The restraining belts correspond to the buckles.

[0012] In an optional solution: symmetrical second fixing blocks are provided on both sides of the connecting sleeve, and fixing belts are provided on the second fixing blocks.

[0013] In an optional solution, a pressure display is provided on the surface of the brace outer shell, and pressure sensors are provided inside the first airbag and the second airbag.

[0014] In an optional solution: the brace cover is a disposable brace, the brace cover is made of soft material, the inner core is a polymer plastic deformable material, the first airbag and the second airbag are made of silicone soft material, and the second airbag has a three-dimensional structure that is thick in front and thin in the back when inflated.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. After the first airbag is inflated, it can continuously apply pressure to the affected arm to prevent the brace from loosening. The airbag contains a pressure sensing device that can automatically sense the pressure changes in the brace airbag. As the swelling intensifies, the pressure in the brace increases. The air can be deflated through the deflation valve. When the swelling subsides, the pressure in the brace decreases. By inflation, the pressure in the brace always maintains the optimal reduction pressure.

[0017] 2. As the swelling subsides, the pressure gradually decreases, and the airbag can continue to inflate to maintain the required pressure. The constant pressure in the brace prevents the brace from loosening, and avoids loss of reduction due to loosening of the plaster, as well as loss of reduction caused by replacing the plaster after loosening.

[0018] 3. After the second airbag is inflated, it maintains the palmar flexion position of the wrist joint. By releasing air through the second airbag's second air hole, the flexion angle can be gradually reduced. When the gas is completely released, the neutral position of the wrist joint can be maintained. Therefore, there is no need to replace the plaster during the treatment process, which can avoid loss of reduction when replacing the plaster. BRIEF DESCRIPTION OF THE DRAWINGS
