Tourniquet Cuff and method for manufacturing same

Abstract

A tourniquet cuff for placement on a limb, has an inflatable body 2 which encloses an inflatable chamber 1 and which can be inflated with a compressed gas so as to create blood flow restriction in thelimb, with the inflatable body 2 being formed from an elongated support 3 made of a bendable support material extending along a longitudinal direction and from a stretchable wall 4 made of a stretchable material attached to the support. In order to enable thorough and easy cleaning and sterilization of the tourniquet cuff and easy placement on a limb and to ensure the most uniform possible distribution of the pressure exerted by the tourniquet cuff on the limb, the stretchable wall is affixed to the elongated support while the stretchable material is stretched at least in the longitudinal direction. A method of manufacturing the tourniquet cuff is also disclosed.

Description

technical field [0001] The invention relates to a tourniquet cuff for placement on a limb and for achieving hemostasis in a limb, and a method for producing such a tourniquet cuff. Background technique [0002] Hemostatic devices in the form of inflatable cuffs are known from the prior art, for example from US Pat. The inflatable cuff is connected to a source of compressed gas for hemostasis in the limb, and is inflated with the compressed gas (or compressed air) so that the cuff exerts a pressure on the limb that is great enough to hold the limb, while being held by the cuff. The blood flow in the section surrounded by the band is at least largely or completely interrupted. Such hemostatic devices are used, for example, during surgery on limbs in which extensive or complete hemostasis or even bloodless areas in the operative field are produced and should be maintained during surgery in order to simplify surgery or reduce the vascular system. risk of damage. To inflate th...

Problems solved by technology

Here, due to the flexible textile structure of the cuff cover, there is the risk that wrinkles will develop in the cover

Creases occur especially when inflating the cuff, since the inner circumference becomes shorter than the outer circumference, thereby creating an excess of material which causes wrinkles

Furthermore, the tourniquet cuff known from US 2013 / 028 96 12 A1 can only be cleaned and sterilized insufficiently, and it is provided only for one-time use, which is disadvantageous in terms of waste generation and from the point of view of resource efficiency. Adverse
