Abstract
Abstract A sleeve for measuring blood pressure has an inner hollow space connected with a source of pressure means. The invention is particularly characterized by the provision of an inner tubular piece consisting of an elastic thermoplastic artificial material and an outer tubular piece of substantially the same length consisting of bendable thermoplastic artificial material which is provided with a connection to the inner space. The inner space is formed by welding the edges of the two pieces, said edges extending substantially transversely to the longitudinal direction of the pieces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A sleeve for measuring blood pressure, comprising an inner tubular piece consisting of an elastIc thermoplastic material, an outer tubular piece enclosing said inner tubular piece and consisting of bendable thermoplastic material with glass fiber reinforcement, said glass fiber reinforcement having glass fiber threads forming a net with some threads extending at an angle of substantially 45* to the longitudinal direction of the tubular pieces, other glass fiber threads extending parallel to each other in said longitudinal direction and located at equal distances from each other equal to the diagonals of the meshes of said net, the inner tubular piece being devoid of glass fiber reinforcement, the two tubular pieces being of substantially equal length, the outer tubular piece consisting of a thicker thermoplastic material than the inner tubular piece, said tubular pieces having adjacent longitudinal edges which are joined by welding defining a flat torus sleeve having a closed inner space formed between the two tubular pieces, and a pressure supplying piece carried by said outer tubular piece and communicating with said inner space.
Claim 2
Dependent Claim
175 words
A sleeve for measuring blood pressure, comprising an inner tubular piece consisting of an elastIc thermoplastic material, an outer tubular piece enclosing said inner tubular piece and consisting of bendable thermoplastic material with glass fiber reinforcement, said glass fiber reinforcement having glass fiber threads forming a net with some threads extending at an angle of substantially 45* to the longitudinal direction of the tubular pieces, other glass fiber threads extending parallel to each other in said longitudinal direction and located at equal distances from each other equal to the diagonals of the meshes of said net, the inner tubular piece being devoid of glass fiber reinforcement, the two tubular pieces being of substantially equal length, the outer tubular piece consisting of a thicker thermoplastic material than the inner tubular piece, said tubular pieces having adjacent longitudinal edges which are joined by welding defining a flat torus sleeve having a closed inner space formed between the two tubular pieces, and a pressure supplying piece carried by said outer tubular piece and communicating with said inner space.
Claim 3
Dependent Claim
28 words
A sleeve in accordance with claim 1, wherein the inner and outer tubular pieces are completely free relatively to each other with the exception of their welded edges.
Claim 4
Dependent Claim
30 words
A sleeve in accordance with claim 1, wherein the inner and outer tubular pieces are also joined along a line extending substantially in the longitudinal direction of the tubular pieces.
Claim 5
Dependent Claim
25 words
A sleeve in accordance with claim 8, wherein said connecting piece consists of a joint made of a thermoplastic material and receiving a connecting hose.
