Description

Technical Field

[0001] The invention relates to the technical field of orthopedic care, and in particular to a bracket with a leg supporting and fixing function. Background Art

[0002] Orthopedic care refers to professional nursing services for diseases or injuries of the bones, joints, muscles and other systems. Its main purpose is to help patients relieve pain, promote wound healing, restore function, prevent complications and improve quality of life through comprehensive nursing measures. Orthopedic care includes care for patients with fractures, joint replacements, spinal diseases, sports injuries, etc., covering aspects such as condition assessment, preoperative and postoperative care, pain management, activity recovery, rehabilitation training, etc.

[0003] For example, a Chinese invention patent (CN108392345A) discloses an orthopedic care bracket with a leg support and fixation function, which records: "The beneficial effect of the present invention is that when the buffer column moves upward, the polarity between the first magnetic pole and the second magnetic pole is the same, then the repulsive force will increase when the distance is reduced, thereby improving the repulsiveness; and when the buffer block squeezes the extrusion block, the spring has a reactionary repulsive force on the extrusion block, which can achieve a buffering and protective effect on the legs and effectively improve the recovery speed of the legs." It also records: "When caring for orthopedic legs, the patient's legs are placed on a bracket installed on the bed, and the height of the bracket cannot be adjusted, and the long-term suspension makes it difficult for the blood in the legs to circulate, which is not conducive to recovery." Technical problems.

[0004] In summary, it can be seen that the prior art uses an upper support plate and a lower support plate to support and fix the patient's legs, but this method has the following technical problems: when the external temperature is low, a thermal blanket is generally required to cover the patient's legs to reduce the low temperature of the patient's legs, and the above-mentioned device lacks a structure to separate the thermal blanket from the patient's leg skin, which may cause the thermal blanket to compress the patient's wound or the thermal blanket and the skin near the patient's wound to move relative to each other, thereby affecting the patient's wound healing. For this reason, the present application proposes a bracket with a leg support and fixation function, which provides a new technical solution to solve the technical problems mentioned in the above-mentioned patent. Summary of the invention

[0005] Based on this, it is necessary to provide a bracket with a leg support and fixing function to address the above technical problems. The support frame can be raised to a suitable height through an electric telescopic rod, and then the patient's legs can be placed on the support plate, and then the patient's legs can be slowly released, and the double-sided rack and the support plate can move downward under the action of the patient's leg gravity, and then the two second gears can be driven by the two first gears to rotate accordingly, so that the two arc-shaped protection frames can slide evenly on the outside of the support frame, and then the arc-shaped protection frames can be unfolded. When the external temperature is relatively low, a thermal insulation blanket can be laid on the base of the device, and the first fleece-side Velcro can be pasted to the first thorn-side Velcro, and the second fleece-side Velcro can be pasted to the second thorn-side Velcro and the third thorn-side Velcro, and then the thermal insulation blanket can be The thermal blanket is fixed to keep the patient's legs warm to avoid the situation where the patient's legs have a low temperature. At the same time, the thermal blanket is supported by the arc-shaped protection frame and the limiting rack, which can avoid direct contact between the thermal blanket and the patient's legs, thereby reducing the thermal blanket from pressing the patient's leg wounds, affecting blood circulation and thus affecting wound healing. It also avoids the situation where the thermal blanket and the patient's leg wounds rub against each other and move, causing secondary injuries to the patient, thereby improving the practicability of the device. In addition, the cooperation of the first thorny surface Velcro, the second thorny surface Velcro and the third thorny surface Velcro with the first fleece surface Velcro and the second fleece surface Velcro facilitates the installation and disassembly of the thermal blanket, thereby facilitating the subsequent cleaning and replacement of the thermal blanket, and also facilitating the dressing change and inspection of the patient's leg wounds, thereby improving the practicability of the device.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The bracket with leg support and fixing function provided by the present invention can raise the support frame to a suitable height through an electric telescopic rod, and then the patient's legs can be placed on the support board, and then the patient's legs can be slowly released, so that the double-sided rack and the support board can move downward under the action of the patient's leg gravity, and then the two second gears can be driven to rotate by the two first gears, so that the two arc-shaped protection frames can slide evenly on the outside of the support frame, and then the arc-shaped protection frames can be unfolded, and when the external temperature is relatively low, a thermal insulation blanket can be spread on the base of the device, and the first fleece-surface Velcro is pasted with the first thorn-surface Velcro, and the second fleece-surface Velcro is pasted with the second thorn-surface Velcro and the third thorn-surface Velcro, and then the thermal insulation blanket is fixed, and the thermal insulation blanket is The patient's legs are kept warm to avoid the situation where the patient's legs have a low temperature.

It also avoids the thermal blanket and the patient's leg wounds rubbing against each other and moving, causing secondary injuries to the patient, thereby improving the practicability of the device. In addition, through the cooperation of the first thorny surface Velcro, the second thorny surface Velcro and the third thorny surface Velcro with the first fleece surface Velcro and the second fleece surface Velcro, the installation and disassembly of the thermal blanket is convenient, thereby facilitating the subsequent cleaning and replacement of the thermal blanket, and also facilitating the dressing change and inspection of the patient's leg wounds, thereby improving the practicability of the device.

[0022] The bracket with leg supporting and fixing function provided by the present invention can control the height of the supporting frame through the electric telescopic rod, and then after comprehensively judging the height that the patient's legs should support according to the patient's body shape, injury condition and the patient's own feelings, the supporting frame can be raised to a suitable position through the electric telescopic rod, thereby improving the flexibility of the device in supporting the height of the patient's legs, and when the device is not in use, the electric telescopic rod can be controlled to drive the corresponding supporting frame to descend to the lowest level, so that the two arc-shaped protection frames are then retracted into the inside of the supporting frame to the maximum extent, so that the bottom of the fixed shell is tightly attached to the top of the sliding block, and due to the limitation of the fixed shell and the sliding block, the double-sided rack cannot slide inside the fixed shell, and then the double-sided rack and the arc-shaped protection frame are folded and locked, thereby reducing the space occupied by the device when it is idle, and the locking between the components after folding can improve the stability of the device, reduce the shaking of the structure inside the device during transportation to cause unnecessary wear, and improve the practicability of the device.

[0023] The bracket with leg supporting and fixing function provided by the present invention can support the patient's legs through the double-sided racks, and can drive the corresponding arc-shaped splints to move toward the patient's legs by pushing the corresponding limiting racks respectively, and then rely on the two arc-shaped splints and the double-sided racks to clamp the patient's legs.
