## Abstract

A stretchable belt (1) provided for medical purposes for use on the body of a patient has at least one sensor (8) for detecting at least one parameter of the patient's body. An adaptation to different body sizes and motions of the patient is provided without separate length adjusting members being necessary or without the need to stock different belt sizes. Furthermore, the belt is able to be manufactured at a low cost and makes possible simple and reliable handling, even for patients. The belt material (1) has at least one material area (2) with a lower spring rate in the longitudinal extension than at least one material area (3) with a higher spring rate of the belt (1).

## Claims

### Claim 1

A stretchable belt for medical purposes for use on the body of a patient, the belt comprising:
a sensor for detecting at least one parameter of the patient's body;
stretchable belt material comprising a first material area occupying a first area of a belt material longitudinal extent in a belt longitudinal direction and a second material area occupying a second, different, area of said belt material longitudinal extent in the belt longitudinal direction, said first material area having a lower spring rate of longitudinal extension in the longitudinal direction than said second material area with a higher spring rate of longitudinal extension in the longitudinal direction, wherein the first material area with the lower spring rate is embodied with perforations and/or interruptions of the belt material with the lower spring rate attained by mechanically altering the structure of the belt material through perforations and/or interruptions in the first material area; and
a blocking means to prevent stretching or allow stretching only slightly of the first material area with the lower spring rate.

### Claim 2 (depends on 1)

A stretchable belt in accordance with claim 1, wherein said first material area with the lower spring rate is activated by removing the blocking means.

### Claim 3 (depends on 2)

A stretchable belt in accordance with claim 2, wherein the blocking means is an adhesive tape and/or a thread.
