Description

[0001] FIELD OF TECHNOLOGY

[0002] The invention relates to medical equipment, namely to orthopedic equipment, in particular to a rehabilitation device for supporting a paralyzed arm.

[0003] PRIOR ART

[0004] From the prior art, similar means, for example, a limb training system based on environmental information (see JP 2002102300 A, published 2002-04-09). The limb training system consists of a training target, for example, a cup and a jug placed on a table and provided with sensor parts, respectively, an instructed path generator that calculates and processes the instructed path in a computing part and outputs it based on information on a number of conditions (environmental information) measured by each sensor part, original information stored in a storage part, and a work task, and a path presentation device having a driving part for driving a support part supporting a training section, for example, the upper limbs, based on the instructed path output by the generator in accordance with the instructed path.

[0005] A manipulator is also known (see NL 1031376 C2, see 2007-09-18), which is intended for a body support device, such as a wheelchair, and has at least one base, to the upper end of which a shoulder is attached, wherein a first end of the upper arm is attached to the shoulder. The manipulator is intended for a body support device, such as a wheelchair, and has at least one base, to the upper end of which a shoulder is attached, with the upper end of the arm attached to the shoulder. The first end of the arm is attached to the opposite second end, which is attached to a gripper with the opposite second end. The manipulator has at least three degrees of freedom and a maximum of five for motorized movement of the gripper relative to the base. The shoulder can rotate relative to the base around the first axis.During use, this first axis extends approximately vertically, and the upper arm can rotate around a second axis that covers an angle with the first axis, which is preferably located at a right angle.

[0006] A device for developing contractures of the upper limb (see SU 1158195 A1, published 1985-05-30) may also be recognized as an analogue of the claimed device. It contains shoulder and forearm splints that are pivotally connected and provided with screw fasteners and are rigidly connected to the corresponding sleeves, characterized in that, in order to ensure the possibility of rotational movements of the forearm, the forearm splints are provided with a rotation mechanism made in the form of a sleeve with an end wall having concentric grooves, and a ring mounted on the sleeve with the possibility of rotation and fixation by means of guide bolts located in the concentric grooves.

[0007] In the applicant’s opinion, the closest analogue may be a rehabilitation device (see GB 2631683 A, published 2025-01-15).An auxiliary device for supporting a user's limb, the auxiliary device comprising a limb support element and an articulated armature having a plurality of levers extending sequentially between a base and a limb support element, wherein each lever is pivotally attached to an adjacent lever and wherein an adjustable resistance mechanism is installed between two adjacent levers in the articulated armature to counteract the load on the limb support element by the user during use, the auxiliary device comprising one or more sensors for determining the movement of the articulated armature and a controller for receiving an output signal from one or more sensors, so that the auxiliary device can be used to evaluate the user's physical capabilities when moving the supported limb.Also disclosed is a physiotherapy system including an auxiliary device and an operator interface device connected to a controller and configured to output information about the user's movements received from one or more sensors.

[0008] Common disadvantages of analog devices are the complexity of their manufacture and use.

[0038] EMBODIMENT OF THE INVENTION

[0039] According to the embodiment of the invention shown in Fig. 1, a rehabilitation device for supporting a paralyzed arm comprises a support frame (1) for accommodating the patient's arm. The support frame includes three arch supports (2): two for the forearm and one for fixing the elbow joint. The supports are secured to two rods (3), allowing for adjustment of the length and width of the support frame. This allows for individual adaptation of the device to each patient, taking into account their anatomical characteristics.

[0040] The middle support arc connects to the arm relief adjustment mechanism (4). This mechanism is designed as a damper, ensuring smooth movement and protecting the joints from sudden loads.

[0041] The support arc, located in the middle part of the bed, is connected to the damper support (5), combined with the means for adjusting the degree of hand unloading (4), the means for adjusting the degree of hand unloading, which can be made in the form of a screw pair, adjusted by a wing nut. The damper support is made in the form of a lever (6), on which a gas lift support (7) is placed. The lever and the gas lift are rotatably connected by a movable, rotating support (8) with a system of at least two levers (6), connected to a clamp (8), containing a shoe and a screw for fastening to a fixed support.

[0042] The rotation of the levers is achieved by means of a bearing, such as a rotary bearing.

[0043] For the patient's convenience and more comfortable placement of the hand, the tray is equipped with a backing, which is made of non-woven fabric and secured with Velcro.

[0044] On the lever connected to the means of fastening to the fixed support, there is a stand for fastening (9) - fixing the bed, which allows you to bring the device into a static state for ease of storage and use.

[0045] A latch-lock is fixed on the stand for fastening the bed for placing the bed rod with the corresponding internal diameter.

[0046] By changing the dimensions of the trays, it is also possible to change the power of the device.

[0047] The device operates and is used as follows.

[0048] Before the procedure, the device can be adjusted to individual dimensions and parameters that determine the degree of the patient's disease by changing the length and width of the tray, adjusting the height and angle of the supporting elements.

[0049] The patient independently removes the arm support from the clamp-fixing post (9), placing the arm in the arm support (1). The arm is preferably secured to the support using Velcro. The arm is positioned in the arm support (1) so that it rests on all three arch supports (2), corresponding to the position of the forearm and elbow. A soft pad provides additional support for the arm.

[0050] Through training and use, the required pressure is adjusted to provide optimal muscle and tendon tension, helping to restore strength and coordination. The load level is mechanically adjusted using the screw mechanism of the hand relief adjustment device (4).

[0051] Using a rehabilitation device to support a paralyzed arm, the patient can perform essential everyday activities, such as holding and moving a spoon, telephone, etc., thereby returning to normal activities without assistance. Simultaneously, the patient performs passive and active exercises aimed at restoring muscle activity and motor coordination, as well as specialized exercises that include various types of flexion and extension movements, as well as rotations of the wrist and palm.

[0052] The rehabilitation process is carried out under the supervision of a specialist who monitors the patient's condition and can give recommendations on the use of the device.

[0053] Using the device promotes the gradual return of lost hand functions, helps prevent the development of contractures and muscle atrophy, and improves overall mobility and functionality of the upper limb.

[0054] Advantages and features of the device:

[0055] Convenient mounting: can be fixed to any supporting, horizontal surface on any table.

[0056] Convenient mechanism for fixing the device.

[0057] The effectiveness of the device has been confirmed by measurements of hand strength and the angle of hand lifting, which revealed improvements in these indicators compared to similar devices.

[0058] The effectiveness of the device also lies in the fact that you can do exercises using the stated device at home, every day.

[0059] INDUSTRIAL APPLICABILITY

[0060] The device is used in medical practice for the rehabilitation of patients with upper limb injuries, such as moderate or severe weakness in one or both arms with partial loss of arm mobility, small range of motion after a neurological disease (stroke, brain injury, multiple sclerosis, myopathy, etc.).
