Problems solved by technology

[0002] At present, during the infusion operation of the existing infusion set, the medical staff generally judge whether the puncture is successful by whether the blood returns, but for various complicated causes, such as severe dehydration, hypotension, shock, vascular contracture, severe diarrhea in children, etc. When venipuncture is performed on patients such as children, obese children, etc., it is not easy to return blood, and the success rate of puncture is low. Sometimes multiple punctures are required to bring unnecessary pain to patients.

Abstract

The invention discloses a negative-pressure intravenous infusion set which can increase the success rate for first puncture and reduces the pain of patients caused by repeated punctures. The infusion set comprises a transfusion tube (3), and a negative-pressure device is arranged on the section of the transfusion tube (3) from a pulley switch to a filter; the negative-pressure device comprises a housing (1), the top face of which is open, and round holes allowing the transfusion tube threading through are formed on the two sides of the housing (1); a leaf spring (4) is arranged on the inner bottom surface of the housing, an extrusion body (8) is arranged in the housing (1), and the extrusion body (8) is connected with the housing (1) through a hinge (7). The invention solves the problems of blind puncture and repetitive failure of puncture exisiting in clinic practice ever since a long time ago.

Description

technical field [0001] The invention relates to a negative pressure intravenous infusion set. technical background [0002] At present, during the infusion operation of existing infusion sets, medical staff generally judge whether the puncture is successful by whether the blood returns, but for various complicated etiologies, such as severe dehydration, hypotension, shock, vascular contracture, and severe diarrhea in children When venipuncture is performed on patients such as children, obese children, etc., it is not easy to return blood, and the success rate of puncture is low. Sometimes multiple punctures are required to bring unnecessary pain to the patient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a negative-pressure venous infusion set that improves the success rate of first puncture and reduces pain caused by repeated punctures. [0004] In order to solve the above-mentioned technical problems, the ...
