Abstract

The invention relates to a blood pressure manometer comprising a housing, a cuff connected to the housing, a cuff storage element in which a section of the cuff can be retracted to adjust the width of the cuff, and a cuff tightener which pulls the cuff section into the cuff storage element with a pre-determined tractive force. The cuff tightener comprises a pre-tensioned spring drive and a detachable withdrawal blocking element which prevents the cuff from withdrawing counter to the spring drive. The spring drive causes the cuff to automatically tighten with a pre-determined force, ensuring reproducible measuring results. The cuff storage element and the cuff tightener can be integrated into or engaged in a locking manner with the housing. An automatic switch-on mechanism switches the appliance on as soon as the cuff storage element is locked to the housing when the cuff is positioned on the limb.
