Tourniquet used for internal arteriovenous fistula in hemodialysis

Abstract

The invention discloses a tourniquet used for internal arteriovenous fistula in hemodialysis. The tourniquet comprises a support base, a long groove which enables a elastic band to be embedded is formed in the upper end surface of the support base, a press piece used for tightly pressing the elastic band is arranged in the part, above the elastic band, of the long groove, one end of the press piece is rotationally connected with the inner side wall of the long groove through a rotation shaft, and protruding pieces are arranged on the outer walls on the two sides at the other end of the press piece. Clamping grooves capable of being matched with the protruding pieces are formed in the inner side wall of the long groove, a pull ring is arranged on the upper surface of the end, where the protruding pieces are located, of the press piece, an embedding groove is formed in the lower end surface of the support base, a sponge block is embedded into the embedding groove, the lower end of the sponge block protrudes out of the embedding groove, and a child inserting fastener and a mother inserting fastener are fixed to the two ends of the elastic band respectively. By adopting the structure,the support base and the sponge block can be prevented from freely moving on the elastic band, and the aim that the sponge block reliably stops bleeding can be achieved.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and relates to a tourniquet for hemodialysis arteriovenous fistula. Background technique [0002] At present, in the process of hemodialysis, it is often necessary to use a tourniquet. The current tourniquet generally includes an elastic band and a hemostatic block installed on the elastic band. The hemostatic clot can move freely on the elastic band, so that it is easy to cause the hemostatic clot to be displaced, which will make the hemostatic clot unable to stop bleeding. Contents of the invention [0003] In order to solve the above problems, the present invention designs a tourniquet for hemodialysis arteriovenous fistula. After the internal support seat and sponge block are adjusted in position, it can prevent the support seat and sponge block from moving arbitrarily on the elastic band. Come, can make the sponge block achieve the purpose of reliable hemostasis. [0004] The pu...
