Description

The invention relates to devices for facilitating the movement of people with diseased lower extremities, namely crutches.

The invention is known as the “Crutch” (RU 2012316, A61H 3/02, 1994), comprising a rod with a tip, an armpit, straight additional racks, S-shaped racks are attached to the middle of them, and the upper ends of the straight additional racks are connected with the axillary, between the lower ends of the direct additional racks mounted handle.

The disadvantage of this crutch is the presence of only two supports: axillary and for the hands.

The well-known "Medical crutch with folding seat" (utility model RU 152269, A61H 3/02, 2015), consisting of a double stand in the upper part, turning into a single support with a rubber tip, crossbars for the armpit in the upper part, handles for hands fixed at the top of the double rack, which can be converted into a seat in the form of a chair on four legs by simply folding the seat by hand.

The disadvantage of this crutch is the presence of only two supports: axillary and for the hands, and the seat is designed to rest and is not a support when walking.

In case of violation of the statodynamic function of the upper limb, the use of crutches with two supports: axillary and for the hands is not possible.

The aim of the invention is the development of vehicles using three fulcrum, with wider functionality and versatility.

To achieve this goal, a three-legged crutch was developed, including a telescopic stand with the possibility of height adjustment and fixation in the desired position, equipped with a cross member with two rubber tips at the bottom, and an armpit support on which the handle for the hands with height and fixation adjustment is put on in the desired position, and in the upper part of the rack there is an axillary support, in the upper part of the telescopic rack there is a socket for the cross member with an eye, to which it is hinged Eden with the possibility of adjusting the width of the pelvis and fixed in position on the end cross member is arranged to nest underarm support strut to be adjustable in height and fixing in position.

The essence of the invention lies in the fact that the proposed crutch has three points of support: axillary, for the hands and pelvis. Used on the damage side, it is universal (can be used both on the left and on the right). On the contralateral side, a support structure of a conventional design may be used.

This design greatly facilitates movement, can be adjusted to the individual characteristics of the patient. With proper adjustment of the structure, the load is evenly distributed to all support points, which ensures comfortable movement.

The technical result from the use of the invention lies in the manufacturability of manufacture, installation, safety and ease of operation.

The design of the proposed tri-crutch is shown in the drawing.

The three-legged crutch consists of a telescopic stand 1, which can be adjusted in height and fixed in position with a screw and nuts 2. At the bottom of the stand there is a crossbar with two rubber tips 3, providing directional and lateral stability.

In the upper part of the rack there is a nest for cross member 4 with an eyelet for attaching the seat. The seat 9 is hinged to the ear. Cross member 4 can be adjusted along the width of the pelvis and fixed in position with screw 5.

The armpit support 6 can be height-adjustable and fixed in position with a screw and nut 2. An axillary support 7 is located at the top of the rack.

A handle for the hands 8 is put on the armpit support column, which can be adjusted in height and fixed in position with a screw and nut 2.

Tricycle crutch is used as follows.

When individually selecting a crutch, four parameters should be considered:

- the total height of the crutch from the tip to the axillary bar;

- the position of the handle to support the hand;

- seat height;

- the width of the device depending on the constitutional characteristics of the patient.

The height of the telescopic stand is adjusted in height with the screw and nut 2 so that the seat 9 is at the level of the patient's pelvis. Then, the seat 9 is moved along the cross member 4 so that the seat is under the patient’s buttock and secured with a screw 5. In the socket located at the end of the cross member, insert the armpit support 6 with the handle 8 and axillary support 7. The armpit support is fixed at the desired height screw with nut 2. Next, install the handle for the hands 8 in the desired position and secure with a screw with nut 2.

Three-legged crutch provides high reliability of the desired patient positioning while walking. The functionality of the three-legged crutch provides for the distribution of load on three reference points: hand, axillary region and pelvis.

The proposed design of a three-legged crutch can be used for:

- violation of the support of one of the limbs;

- during the period of early rehabilitation;

- in the early postoperative period with TEP of the hip, knee joints;

- with amputation of the stump of the lower limb at different levels in the postoperative period;

- MOS of lower limb segments with external fixation devices;

- the condition after surgical treatment for fractures of the proximal femur, intraarticular fractures of the knee and ankle joints, if necessary, the exclusion of support on the lower limb;

- violation of the statodynamic function of the upper limb;

- the impossibility of using other means of support.
