Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-3:

a windowing type polymer radius distal end small splint provided with a pressure receptor comprises a radius plate 1, a dorsal plate 11, an ulnar plate 12, a palmar plate 13 and a plurality of strapping tapes 3, wherein the radius plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate 13 are made of polymer materials, the upper part, the middle part and the bottom of the upper surface of the radius plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate 13 are all provided with fixing belt holes 2 at equal height positions, and the strapping tapes 3 are arranged among the fixing belt holes 2 in a penetrating manner to sequentially connect the radius plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate in series; the back side plate 11 and the palm side plate 13 are both provided with windows 4, and one side of each window 4 is hinged with a cover plate 5 through a hinge 6; and a pressure sensor is arranged in the middle of the palm side plate or the back side plate, and a display 7 connected with the pressure sensor is arranged at the top of the palm side plate or the back side plate.

The pressure sensor 8 preferably adopts a piezoelectric pressure sensor, and pressure sensors widely applied in the medical field at present mainly comprise a resistance type pressure sensor, a piezoelectric pressure sensor, a capacitance type pressure sensor, a piezoresistive type pressure sensor, an optical fiber type pressure sensor, an integrated pressure-sensitive sensor and the like. The resistance type pressure sensor has larger components and weak output signals; the piezoelectric pressure sensor has high sensitivity, small volume and light weight; the piezoresistive pressure sensor has wide frequency band, high sensitivity and light weight; when selecting pressure sensors, piezoelectric pressure sensors are undoubtedly the best choice in view of the requirements of light weight, small size, high sensitivity and no harm to skin.

As the preferred scheme, the radial plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate 13 are all made of high molecular polyester plates, have the characteristics of light weight, good air permeability, high plasticity and convenient manufacture, can be quickly manufactured by combining a 3D printing technology, and the fixing belt holes 2 can also be integrally formed so as to avoid the subsequent installation of the fixing belt holes 2. The two points of light weight and good air permeability are obviously higher than the plate selected by the traditional material; the plasticity is high, the individual requirements of different patients are fully met, and the shape of the splint is customized and corrected in a targeted manner; the characteristic of convenient manufacture is that the material is softened by soaking in hot water at 65-70 ℃ for 4-5 minutes, so that the design concept of windowing can be adjusted and modified according to specific conditions. The size and shape of the window 4 can be modified according to the forearm condition of the patient by simply using a tool, so that the window 4 can adapt to the dressing change requirements under different conditions. Make the design of windowing and macromolecular material's organic combination, when showing both sides characteristics, make clinical practice possible again, in order to apron and window can closely cooperate, all be provided with sealed boss in the marginal upper portion of apron and the marginal lower part of window.

In order to facilitate the connection and the release of the binding belt 3, the fixing belt hole 2 is integrally formed with the radial plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate 13.

The two sides of the radial plate 1, the dorsal plate 11, the ulnar plate 12 and the palmar plate 13 are all provided with radians (the radians are measured according to the hand shape of the patient), so that the two sides can be better attached to the arm of the patient, and the compressive stress is reduced.

The traditional small splint has great obstruction in dressing change. In order to increase the treatment effect, the healing of the affected part is promoted by adopting the traditional Chinese medicine ointment while the small splint is adopted for fixation, and the fixed splint needs to be removed for dressing change operation.

And this design has carried out breakthrough's institutional transformation on the basis of traditional splint to radius distal end fracture, increases the window 4 of hinge 6 connection on the splint, and under the closure state, window 4 is closed, and each splint is in the enclosed state as a whole, and the stress state can not be because of window 4 dispersion, can not exert an influence to the fixed effect of splint.

After the window is opened, the areas of the windows on the two adjacent small clamping plates and the gaps between the clamping plates are added, so that the affected part is fully exposed, and the ointment is removed and stuck through the magic tape. Due to the design of windowing, the complex process that the traditional small clamping plate needs to be disassembled for dressing change is simplified. The contradiction between different requirements of different medicines and inconvenience and risk caused by the disassembly of the splint in different time periods in the initial stage of fracture is solved. Compared with the mode of fumigation for carrying out drug treatment on the affected part, the small splint is convenient to open the window without bringing redundant time burden, and brings better curative effect due to direct long-term contact with solid drugs, thereby overcoming the defects that the traditional small splint is not independent and tedious in operation of externally applied drugs and brings secondary damage. And when necessary, the small splint window is opened, the dressing change process is simple and convenient, and when the pressure is overlarge, the small window is opened, so that the pressure can be released to a certain degree, and the effect of balancing the pressure is achieved.

Compared with the existing hollow-out type clamping plate, the hollow-out type small clamping plate can influence the stress of the clamping plate, so that the small clamping plate loses good supporting and fixing effects; and the design of fretwork can make the forearm of swelling find to declare the mouth and thus make pressure to fretwork gathering, leads to near the fretwork to produce serious indentation, leads to local capillary's fracture even, so it is not a good choice to fretwork the splint for a short time. And the small splint is windowed, and in a closed state, the small splint is a complete closed structure, so that the burden is not generated. In the process of changing dressings, the strapping in the middle of the loosening, open the purpose that the fenestrate can reach again and change dressings, and because the fixed and supporting role of two strapping in addition, the affected part can not produce fracture end aversion at this in-process yet, causes the secondary damage. After accomplishing the dressing change, the strapping restores to suitable elasticity degree with little splint under the help of baroreceptor for the process of changing dressings need not dismantle splint, reaches the patient and does not need the doctor to do the parent and do the purpose that also can convenient dressing change, with this healing that promotes the fracture.

Set up electron sensor main part (pressure sensor) between splint and the human tissue, utilize the pressure size between electron sensor main part detection splint and the human tissue to digital display and scintillation warning light warning remind the patient to carry out the elasticity regulation of strapping, can avoid effectively because of the limbs necrosis that splint tension leads to, also can reduce because of the splint tension leads to the risk of fracture aversion too.
