This utility model provides a leg brace for preventing pressure injuries, relating to the field of nursing equipment technology. It includes a transverse bidirectional drive seat, a longitudinal drive seat, a leg support frame, a limiting and blocking component, a first strip-shaped airbag, a second strip-shaped airbag, and a strip-shaped roller massage component. The device is clamped and fixed to a hospital bed for use. The patient's legs are placed on the upper end of the leg support frame. The height of the leg support frame is adjusted by the longitudinal drive seat to regulate the support height of the legs. When the legs are supported, the upper end of the strip-shaped square bar can be moved left and right to relieve muscle fatigue caused by maintaining one position for a long time. The first and second strip-shaped airbags are both inflatable airbags, supporting the legs to ensure comfort. When leg muscles are fatigued, the patient can move to the strip-shaped roller massage component for faster muscle relief, achieving long-term leg support and keeping the heels suspended.

Collapsible storage container stands are shown and disclosed. In some embodiments, the stand includes first and second planar frames pivotably attached to each other and each defining an opening sized to receive a storage container. The stand additionally includes first and second legs pivotably attached to the first frame, and third and fourth legs pivotably attached to the second frame. The stand further includes a first leg brace attached to the first leg, and a second leg brace attached to the fourth leg. The first and fourth legs are pivotable to place the first and second leg braces on first and second roof portions of a roof. In some embodiments, the stand additionally includes first, second, third, and fourth support arms pivotably attached to the first and second frames.

A leg brace with interactive force acquisition function suitable for lower limb rehabilitation robots includes a brace body, an inflatable airbag, and an interactive force acquisition system. The brace body can be fitted onto the leg. The inflatable airbag is disposed inside the brace body. The interactive force acquisition system includes a flexible thin-film pressure sensor and a signal acquisition device, realizing the integrated function of leg fixation and precise interactive force acquisition. The flexible thin-film pressure sensor is disposed inside the inflatable airbag. The flexible thin-film pressure sensor is connected to the signal acquisition device for direct acquisition of interactive forces. This invention achieves the integration of leg fixation and precise interactive force acquisition, combining high adaptability, high measurement accuracy, good comfort, and safety. It can provide reliable interactive force parameters for lower limb rehabilitation robots, assisting in personalized rehabilitation training and improving the accuracy and safety of rehabilitation training.

A connecting-plate-type support mechanism of a tripod, including a connecting component, three support leg assemblies and a center column. An outer circumference of the center column is provided with at least one raised rib or groove. An inner side of each support leg assembly is provided with a leg brace. An end of an outer leg tube of each support leg assembly is provided with a locking wrench socket. A side of the locking wrench socket is provided with a protrusion, on which an external articulation base is provided. One end of the leg brace is fixed on an inner side of the outer leg tube through the external articulation base. An outer circumference of a connecting sleeve is provided with an inner articulation base corresponding to the protrusion. The other end of the leg brace is articulated with a side of the inner articulation base.

A strain sensor for a leg brace and a real-time interactive detection system for lower limb rehabilitation are disclosed. The sensor includes a leg brace body and strain gauges mounted on the leg brace body. A double-hole, narrow-beam stress concentration structure is provided at the point of maximum torque near the exoskeleton drive end of the leg brace body. The strain gauges are mounted on the stress concentration structure. The stress concentration structure is designed based on finite element mechanical simulation and is used to concentrate stress and facilitate strain detection. This system, through a self-developed strain gauge leg brace-type human-machine interactive force sensor structure, combined with multi-level noise reduction filtering and high-precision force calculation algorithms, achieves real-time, accurate, and stable detection of human-machine interactive forces during lower limb rehabilitation training. This provides reliable data support for intelligent closed-loop control, active / passive mode switching, and quantitative evaluation of rehabilitation effects of lower limb rehabilitation robots, reducing equipment costs and improving clinical adaptability and widespread adoption.

The present invention provides an adjustable fixing brace comprising a lower leg, a thigh, a hip joint brace, and knee and hip adjustment parts. The second serration on the side surface of the knee joint adjustment part engages with the first serration of the first connecting part of the lower leg brace. The lower first fixing part has a groove, and the upper second fixing part has a third serration. The lower end of the third fixing part extends into the groove within the third opening in the middle to push and rotate. The upper end of the locking block of the first pushing part of the limiting component within the second opening engages with the third serration. A retaining ring in the middle is connected to the second pushing part via a first spring, and a second spring is fitted on the lower part. The retaining ring compresses the second spring for adjustment. In the hip joint adjustment part, the thigh brace connecting part has a buckle, the fourth fixing part of the hip brace connects to a support column, and the upper rotating part is fitted onto the support column. One end of the upper rotating part has a fourth serration. The fifth serration on the upper surface of the lower rotating part engages with the fourth serration and can rotate around the support column. A third spring between the fourth fixing part and the upper rotating part lifts the upper rotating part. The upper part of the support column is fitted with the adjustment part and fixed to the first screw hole of the support column by screws.
