Abstract
A tourniquet includes an elastic band including uneven top and bottom surface. The uneven surface includes rows of a plurality of spaced first uneven zones and rows of a plurality of spaced second uneven zones. The first uneven zone is disposed between two adjacent ones of the second uneven zone. The second uneven zone is disposed between two adjacent ones of the first uneven zone. The first and second uneven zones are concave rectangular. Each uneven zone includes two raised, opposite inclined edges and the other two raised, opposite inclined edges. A ridge is formed between two adjacent inclined edges of different uneven zones.

A tourniquet, comprising:
- an elastic band including an uneven surface on each of top and bottom surfaces, the uneven surfaces and the elastic band being formed integrally, each of the uneven surfaces including a plurality of rows of a plurality of spaced first uneven zones and a plurality of rows of a plurality of spaced second uneven zones, the first uneven zone being disposed between two adjacent ones of the second uneven zone, and the second uneven zone being disposed between two adjacent ones of the first uneven zone;
- wherein the first uneven zones are substantially rectangular and concave toward its center;
- each of the first uneven zones include two raised, opposite first inclined edges, two raised, opposite second inclined edges, and four corners;
- length of the second inclined edge is greater than that of the first inclined edge;
- height of the first inclined edge is greater than that of the second inclined edge;
- the second inclined edges and the elastic band are oriented lengthwise;
- the second inclined edges are parallel to one another;
- extent of an elastic deformation of the second inclined edge is greater than that of the first inclined edge;
- the second uneven zone is surrounded by two second inclined edges of two adjacent first uneven zones of the same row and two first inclined edges of two adjacent first uneven zones of two spaced rows of the first uneven zones;
- the second uneven zones are substantially rectangular and concave toward its center;
- each of the second uneven zones include two raised, opposite third inclined edges and two raised, opposite fourth inclined edges;
- a first ridge is formed between the first inclined edge and the third inclined edge;
- a second ridge is formed between the second inclined edge and the fourth inclined edge;
- height of the first ridge is greater than that of the second ridge;
- length of the fourth inclined edge is greater than that of the third inclined edge;
- the concave first uneven zone has a first depth;
- the concave second uneven zone has a second depth;
- and the first depth is greater than the second depth.
