Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a pressure sore prevention and fracture fixation device. Background Art
[0002] If the ankle is fractured and the heel is in contact with the bed sheet, long-term pressure will easily cause pressure sores. Therefore, considering the risk of pressure sores, it is necessary to wrap the ankle with a cushion or other material. This can not only provide ventilation and prevent the occurrence of pressure sores, but also fix the fracture.
[0003] However, existing pressure sore and fracture fixation devices have many defects. For example, in order to ensure smooth blood flow at the injured area, the foot should be placed diagonally upward. However, existing fixation devices cannot complete this operation. It is necessary to use a sling or the like to achieve the above purpose. However, the adjustment of the sling is relatively difficult, and it is also uncomfortable for the patient to maintain an upward diagonal angle for a long time. Therefore, we propose an anti-pressure sore and fracture fixation device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] Example: Figure 1 As shown, a pressure sore prevention fracture fixation device includes a wearable component 10 for wrapping a fracture site. The wearable component 10 includes a first clamp 101 and a second clamp 102 that are rotatably connected to each other. Figure 2 As shown, a first soft pad 105 and a second soft pad 104 are padded along the inner sides of the first clamp 101 and the second clamp 102. The soft pads and the clamps can be fixed by bonding or other methods. The first soft pad 105 and the second soft pad 104 are made of soft breathable material. The sole of the foot is placed in the second soft pad 104, and the calf is placed in the first soft pad 105. Since the soft pads are made of breathable material and are relatively soft, the problem of pressure sores caused by excessive pressure can be avoided as much as possible. In addition, the heel is suspended in the air, so the problem of pressure sores will not occur.
[0027] Among them, such as Figure 1 As shown, a base 20 is fixedly sleeved on the outer side of the bottom of the first clamp 101, and a rotating portion 21 is integrally provided on one side of the base 20. A bottom plate 30 is provided below the rotating portion 21, wherein the bottom plate 30 and the base 20 are connected through the rotating portion 21. In addition, a support plate 40 is provided between the bottom plate 30 and the base 20 for supporting and adjusting the inclination angle of the base 20, as shown in FIG. Figure 4 As shown, a connecting seat 22 is also provided at the middle position of the base 20, the upper end of the support plate 40 is rotatably connected to the connecting seat 22, and the other end is fixed to the upper end surface of the bottom plate 30, in order to make the support plate 40 adjustable, as shown in FIG. Figure 1-2As shown, a slot 31 is provided on the upper end surface of the bottom plate 30 at a position corresponding to the lower end of the support plate 40. The slots 31 are provided in several groups. According to the needs of the patient, the other end of the support plate 40 can be inserted into different slots 31 to make the base 20 have different tilt angles, making it easier for the patient to lie still.
[0028] Among them, such as Figure 2 As shown, a binding belt 103 is provided on the upper end surface of the first clamp 101 and the side wall of the second clamp 102, which can be used to tie the fixing device to the patient's ankle;
[0029] Among them, such as Figure 1-3 As shown, a variable elastic member is further provided between the first clamp 101 and the second clamp 102, and the elastic member can be removed from the first clamp 101 and the second clamp 102. The elastic member includes an airbag 50 and an air nozzle 51 provided on the side of the airbag 50. The airbag 50 can be inflated. By connecting the air nozzle of an inflation device (not shown) and the air nozzle 51, the airbag 50 is inflated by the inflation device to change the angle between the first clamp 101 and the second clamp 102. During the patient's recovery period, plantar flexion of the patient's ankle can be achieved. In addition, the ankle can be dynamically expanded and contracted, for example, by connecting a device that can inflate and inhale air (not shown) to achieve frequency expansion and contraction of the airbag 50, thereby achieving rehabilitation training for the patient's ankle.
[0030] Among them, such as Figure 3 As shown, an adhesive piece 106 is further provided at the upper end of the first clamp 101 and at a position corresponding to the side wall of the second clamp 102 and the airbag 50. The adhesive piece 106 is a Velcro, and a matching surface is provided at a position corresponding to the airbag 50 and the Velcro, which is used to fix the airbag 50 on the first clamp 101 and the second clamp 102, and the airbag 50 can also be removed from the clamp.
[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
