Description

Technical field

This utility model relates to the main elements/components of devices such as adjustable functional supports intended for rehabilitation and habilitation activities in patients with disabilities in health, with impaired functions of the lower extremities, hip girdle and spine, with diseases of the central nervous system, including number of children with cerebral palsy. The utility model can be used in devices such as adjustable functional supports that provide support and placement of patients in vertical, horizontal or inclined positions during positional therapy, both at home and in medical institutions.

State of the art

A corrective device for the lower extremities is known, disclosed in the RF patent for utility model No. 191738 (publ. 29.04.2019, IPC A61H 3/00). The known device contains a belt and associated rods, made in the form of elastic bands. The lower ends of the elastic linen are equipped with elements for fixing the feet in the form of loops. However, the known device requires significant improvement in order to ensure reliable fixation of the limbs when the user's body is verticalized. This is due to the predominance of flexible connecting nodes in the design, which are deformed during fixation of the limbs and do not provide reliable support for the body. In addition, the device is not adapted for installation on a rigid support, does not contain the necessary components for this, and the revision will require a partial revision of the device design.

Known apparatus for the lower limbs and torso for patients with cerebral palsy, disclosed in the RF patent for utility model No. 204629 (publ. 06/02/2021, IPC A61F 5/00). The known apparatus includes a corset on the torso and cuffs connected to each other by means of rod tires. The cuffs provide a girth of the lower extremities of the patient at the level of the thigh and lower leg. The tightening of the cuffs on the thighs and legs is carried out with the help of tapes and Velcro fasteners. However, the known apparatus requires significant improvement in order to ensure reliable fixation of the lower extremities when the human body is verticalized. This is due to the fact that the cuffs do not provide a reliable support of the limbs when the user's body is verticalized, since they do not have a reliable rigid support that is resistant to deformation when in contact with body parts that are most often in tension when the body is verticalized. In addition, ensuring the possibility of fixation on a rigid support will require a significant revision of the apparatus design.

Known stander knee, disclosed in the patent of the Russian Federation for utility model No. 207896 (publ. 207896, IPC A61F 5/37). Known stander includes U-shaped knee pads, which have horizontal pins and latches to allow horizontal adjustment of the knee pads on the vertical racks of the stander. However, the known device is characterized by insufficient reliability of fixing the user's knees in the stander. This is due to the U-shaped shape of the knee pads, which does not provide a reliable grip of the knee from all sides, which, in turn, limits the possibility of fixing the thigh, lower leg or knee during the anterior or posterior verticalization of the user's body. In addition, the implementation of the knee stops limits the possibility of adjusting their position in depth and height.
