Abstract
Abstract The invention relates to a method and device for an emergent treatment of hypovolemic shock caused by loss of blood. According to the new method an elastic covering tube is applied onto the injured part of a patient's body, said tube possessing two main characteristics: (1) it is twisted along its horizontal axis as a rolled-up tube the end of which is rolled onto said body parts and (2) the material used for the elastic tube has to provide a pressure of between 100 to 400 mm Hg and to possess a critical elasticity coefficient. The critical elasticity coefficient being defined by a given formula which correlates the thickness of the material, unstretched radius and length of the tube, and length and radius of the injured part of the body to be covered.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A method for emergent treatment of hypovolemic shock, comprising the step of: applying a gradual pressure to a portion of a patient's body without any decrease in the pulmonary vital capacity, by inserting a distal end of said portion of said patient's body through a sock-shaped covering tube having a free end and a stationary end, said tube being applied as a roll with said free end of said tube being radially outward of said stationary end; and then, unrolling said tube so that said stationary end remains stationary along said portion of said patient's body while said free end moves proximally along said portion of said patient's body until all of said portion of said patient's body is covered, thus providing a radial tension around said portion of said patient's body whereby said covered portion of said patient's body is exsanguinated.
Claim 2
Independent Claim
142 words
A method for emergent treatment of hypovolemic shock, comprising the step of: applying a gradual pressure to a portion of a patient's body without any decrease in the pulmonary vital capacity, by inserting a distal end of said portion of said patient's body through a sock-shaped covering tube having a free end and a stationary end, said tube being applied as a roll with said free end of said tube being radially outward of said stationary end; and then, unrolling said tube so that said stationary end remains stationary along said portion of said patient's body while said free end moves proximally along said portion of said patient's body until all of said portion of said patient's body is covered, thus providing a radial tension around said portion of said patient's body whereby said covered portion of said patient's body is exsanguinated.
Claim 3
Dependent Claim
28 words
A method according to claim 1, wherein a portion of the rolled tube remains rolled in order to provide radial tension around a proximal portion of the extremity.
Claim 4
Dependent Claim
84 words
The method of claim 1, wherein said tube has an elastic constant (K) and provides a pressure (P) on said portion of the body of between 100-400 mm Hg according to the following equation: ##EQU2## wherein: h=thickness of the material, r o =unstretched radius of the tube, r=radius of the portion of the body to be covered, L 1 =length of the portion of the body to be covered, L o =length of the tube; and P is between 100 to 400 mm Hg.
