DETAILED DESCRIPTION
[0019] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] It should be noted that the leg fixing device of the present invention is usually placed next to a bed or a stool, generally a bed. During treatment or rehabilitation, orthopedic patients can use the leg fixing device of the present invention to fix their legs. The leg fixing device of the present invention is generally placed on both sides of the bed. When the orthopedic patient only needs to fix one leg, one of the leg fixing devices can be removed.
[0021] Embodiment: A leg fixation device for orthopedic care, such as Figure 1-2 As shown, the leg fixing device includes a support seat 1, a clamping member 4, a driving mechanism, a support frame and an inflatable device (not shown in the figure). The support frame is used to support the support seat 1, and the support frame includes a base plate 21, a universal wheel 22 and a telescopic mechanism. The universal wheel 22 is installed at the bottom of the base plate 21. In order to fix the leg fixing device on both sides of the bed, specifically, the universal wheel 22 is a self-locking universal wheel 22. The telescopic mechanism includes an outer support tube 231, an inner support tube 232 and a tightening bolt 234. The lower end of the outer support tube 231 is fixed to the base plate 21, the upper end of the inner support tube 232 is fixed to the bottom of one end of the support seat 1, and the lower end is inserted into the outer support tube 231. The outer support tube 231 and the inner support tube 232 are both elliptical tubes. The inner support tube 232 is provided with a plurality of limiting holes 233 at equal intervals along the height direction, and the outer support tube 231 is provided with a mounting hole. The tightening bolts 234 are used to be installed in the mounting hole and the limiting hole 233 to ensure a stable connection between the outer support tube 231 and the inner support tube 232.
[0022] In the above technical solution, the setting of the telescopic mechanism enables the support seat 1 to be adjusted in height according to the needs. When adjusting, it is only necessary to loosen the tightening bolt 234, and then pull the inner support tube 232 upward or downward to align the mounting hole on the outer support tube 231 with another limit hole 233 of the inner support tube 232 at a suitable height, and then tighten the tightening bolt 234. It is simple and convenient to use. The outer support tube 231 and the inner support tube 232 are both located on both sides of the end of the bed. One end of the support seat 1 is connected to the inner support tube 232, and the other end extends to the other side of the end of the bed, so that orthopedic patients can place their legs on the support seat 1 more conveniently and comfortably after lying on the bed.
[0023] Preferably, the inflatable device is used to drive the clamping member 4 to clamp, and the inflatable device can be an external device or a device installed separately on the bottom plate 21, the outer support tube 231 or the support seat 1, and is not specifically limited. Specifically, the inflatable device is an air pump or others.
[0024] like Figure 1-6As shown, the support seat 1 is provided with a groove 3 for placing the patient's legs. The groove 3 is an arc-shaped groove and a support airbag 5 for contacting the orthopedic patient's legs is fixed on the inner surface. After the leg is fixed in the groove 3, the skin is in close contact with the support airbag 5. If it is not breathable, human sweat cannot be dissipated, which will make the local skin moist, creating conditions for the growth of bacteria and fungi, and increasing the risk of skin infection. Therefore, in order to improve the breathability and patient comfort, the surface of the support airbag 5 is evenly distributed with multiple convex strips 8 along the length direction of the patient's legs to facilitate air circulation. The clamping member 4 is located on the opposite sides of the groove 3 and is used to clamp the patient's legs. The driving mechanism is located on the opposite sides of the groove 3 and is used to automatically adjust the clamping distance of the clamping member 4 according to the specific conditions such as the thickness and shape of the patient's legs.
[0025] Preferably, the driving mechanism includes an active channel 77, a driving airbag 71, an active column 73, a receiving groove 76, a spring 74 and a plurality of steel balls 72. A top plate 6 is provided on the top surface of the support seat 1, and the top plate 6 is detachably connected to the support seat 1 by screws. Two top plates 6 are provided, and the two top plates 6 are symmetrically arranged on opposite sides of the groove 3 along the length direction of the patient's legs. The active channel 77 is located between the support seat 1 and the top plate 6. The active channel 77 includes an arc channel 771 and a straight channel 772. The straight channel 772 is arranged at both ends of the arc channel 771. One end of the straight channel 772 is connected to the arc channel 771, and the other end is connected to the groove 3. The arc channel 771 is projected in a semicircular shape when viewed from above, and the cross sections of the arc channel 771 and the straight channel 772 are both circular. The driving airbag 71 is accommodated and fixed in the middle position of the arc-shaped channel 771. The driving airbag 71 is inflated by the inflation device. Specifically, the supporting airbag 5 is connected to the inflation device, and an air pipe is connected between the supporting airbag 5 and the driving airbag 71. A plurality of steel balls 72 are respectively accommodated in the arc-shaped channel 771. The movable column 73 is located in the linear channel 772 and one end is fixed to the clamping member 4, and the other end is in contact with the steel ball 72. The steel ball 72 is located between the driving airbag 71 and the movable column 73.
[0026] The receiving groove 76 is provided on opposite sides of the linear channel 772, and a limit block 75 is fixed on the side of the movable column 73 close to the steel ball 72, and the limit block 75 is located in the receiving groove 76. The length direction of the spring 74 is consistent with the axial direction of the movable column 73, and the spring 74 is located in the receiving groove 76, and one end of the spring 74 is fixed to the limit block 75, and the other end is fixed to the inner wall of the receiving groove 76, so as to realize the automatic reset function of the clamping member 4.
[0027] There are two driving mechanisms, which are symmetrically arranged on opposite sides of the patient's legs. Each driving mechanism is provided with two clamping members 4 arranged along the length direction of the patient's legs, that is, the orthopedic patient's legs are clamped front and back by four clamping members 4, and the clamping effect is better.
[0028] In the above technical solution, since the support airbag 5 is connected to the driving airbag 71, when the support airbag 5 is inflated by the inflation device, the driving airbag 71 will also be inflated, thereby squeezing the steel balls 72 to both sides. Under the squeezing of the driving airbag 71, the steel balls 72 will push the movable column 73 and the clamping member 4 to move toward the orthopedic patient's leg until the clamping member 4 contacts and clamps the surface of the patient's leg. Since the movable column 73 is driven by the driving airbag 71 and the steel balls 72, the moving distance of the movable column 73 has an adaptive effect. When a certain clamping member 4 is already clamped very tightly, the steel balls 72 will naturally not continue to push the movable column 73 to slide, but push another movable column 73 to slide, so that the clamping member 4 on the other movable column 73 can be quickly clamped. The extension distance of the clamping member 4 can be automatically adjusted according to the specific conditions such as the thickness and shape of the orthopedic patient's leg, and has good adaptability.
[0029] like Figure 1-5 As shown, the clamping member 4 includes a disc-shaped clamping block 41, which is located in the groove 3 and contacts the side wall of the groove 3. One side of the clamping block 41 is fixed to the movable column 73, and the other side is provided with a protective pad 42. In order to protect the legs of orthopedic patients and to improve the clamping comfort and clamping stability, the protective pad 42 is preferably a sponge pad, a rubber pad, a silicone pad or an airbag pad.
[0030] In the above technical solution, the legs of orthopedic patients are clamped front and back by four clamping members 4. For this purpose, the present invention fixes a protective pad 42 on the surface of the clamping block 41, which can improve the clamping stability on the one hand, and play a good protective role on the other hand to prevent the patient from being clamped, while also correspondingly improving the clamping comfort.
[0031] Usage process and principle: After the orthopedic patient lies on the bed, he only needs to put his legs into the groove 3 to support the patient's legs through the groove 3, and then start to inflate the support airbag 5. At this time, the support airbag 5 expands to support the patient's legs through the support airbag 5, which is comfortable. While the support airbag 5 is inflated, the gas will also enter the driving airbag 71 to expand the driving airbag 71, thereby squeezing the steel balls 72 at both ends. Under the push of the steel balls 72, the movable column 73 slides in the linear channel 772. At this time, the spring 74 is compressed, and the pressing block will automatically adjust the moving distance according to the specific situation of the patient's legs. After the legs are completely clamped by the four clamping blocks 41, the inflation is stopped. When the legs stop being fixed, it is only necessary to deflate the support airbag 5. At this time, the driving airbag 71 will also shrink synchronously. Under the action of the spring 74, the movable column 73 and the clamping block 41 will automatically reset, and the clamping block 41 will release the fixation of the patient's legs. It is simple and convenient to use.
[0032] In summary, the present invention is very flexible to use, adopts pneumatic adjustment, is not only easy to adjust, but also can automatically adjust according to the specific conditions of the orthopedic patient's leg thickness, shape, etc., has good adaptability, and improves versatility. In addition, the present invention is supported by the support seat and clamped by the clamping piece, and the overall structure is very stable.
[0033] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
