Abstract

Use of a vibration cuff for optimized fitting and facilitating the fitting of prostheses, wherein the vibration cuff a cuff (1) with at least one to a maximum of four vibration motors (4, 5, 6, 7) and a microcontroller (3) and a start-stop button (2) which are mounted on the cuff, wherein the cuff (1) is arranged on a prosthesis and are generated by the at least one vibration motor (4, 5, 6, 7) algorithmically controlled by the microcontroller (3) vibrations.

Description

The invention relates to a special use of a vibration cuff for optimized adaptation and ease of fitting a prosthesis.

Adaptation and Anprobehilfen for prostheses are known in various variations, with these only an attempt is made to allow by manual movement of the stump mass entry into the prosthesis. Due to the uneven body mass and the different skin thickness of the amputation, some parts of the prosthesis are not filled optimally and thus amputation of skin and tissue is compressed, which prevents the blood circulation and leads to bruises.

From the DE 10 2009 034 708 A1 For example, an apparatus and a method for generating a vibration pattern are known. Here, by means of a drive and a mass, which is set in a rotational movement, a vibration pattern to be generated and detected and provided via a sensor device, the data, wherein pressure sensors, load sensors, torque sensors, motion sensors and / or temperature sensors are used.

From the US 5,730,705 A an ultrasonic transducer for endoprostheses is known, which can be attached by means of a cuff, for example, on an arm or a thigh and promote bone growth.

From the US 2008/0119944 A1 For example, a vibratory drive is known, which is used for inserting an endoprosthesis, for example a hip joint prosthesis, in order to drive it into the existing femur.

Next is from the KR 100699546 B1 a vibration cuff for simultaneous massage and heating of a knee joint known.

The present invention is therefore based on the object to eliminate the existing disadvantages and to achieve an improvement of the adaptation and fitting.

According to the invention, the use of a vibration sleeve with the features of claim 1 is provided to achieve the object. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The vibration generated by the vibration motors stimulates the tissue and allows an efficient entry into the prosthesis. At the same time, the vibrations optimally introduce the tissue into the prosthesis mold, minimizing the risk of tissue squeezing.

It should be noted that the degree of vibration varies according to body mass and tissue condition and is adjusted by the responsible technician.

In a particular embodiment of the invention, it is provided that the position of the vibration motors on the sleeve is to be arranged in a circular shape and contralateral. Furthermore, the elastic cuff allows ideal positioning of the vibration cuff on the prosthesis.

The rotation speed as well as the direction of rotation is here calculated and controlled by a microcontroller according to an algorithm.

The axes of rotation of the vibration motors can be diagonal.

The invention will be explained in more detail below with reference to FIGS.

1 shows a perspective view of the invention used with elastic cuff vibration cuff, mounted thereon vibration motors and the microcontroller used for the control of the vibration motors.

2 shows the perspective view of the vibration motors and their diagonal axis of rotation, which each produce a horizontal and a vertical movement.
