Intelligent indwelling needle based on anticoagulation and blood coagulation coatings

Abstract

The invention provides an intelligent indwelling needle based on anticoagulation and blood coagulation coatings. The intelligent indwelling needle comprises a medical indwelling steel needle, a connector, a connecting pipe, a three-way valve, a medical catheter, a positive pressure valve, a positive pressure connector, a quantity control regulating valve, a blocking plug, a needle holding handle and anti-skid holes, one end of the connector is in threaded connection with the right end of the interior of the connecting pipe, and the other end of the connector is in threaded connection with theleft end of the medical indwelling steel needle; and the left end of the connecting pipe is in threaded connection with the right end of the three-way valve. Through the arrangement of a mounting sleeve, a protective pad, anti-falling lacing main belts, fixing secondary buckles, anti-falling lacing secondary belts and fixing primary buckles, the fixing effect is achieved, falling is avoided, the indwelling stability is guaranteed, and after the medical indwelling steel needle is pricked into the vein of the human body and successfully indwelled, the anti-falling lacing main belts and the anti-falling lacing secondary belts can be connected to the wrist of a patient in a holding mode, the fixing secondary buckles and the fixing primary buckles are mutually buckled and firmly fixed, the anti-skid supporting effect can be achieved through the protective pad, the indwelling stability is guaranteed, and falling is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an intelligent indwelling needle based on anticoagulation and coagulation coating. Background technique [0002] The use of indwelling needles can reduce the pain and fear of injections caused by repeated venipuncture in children, relieve the anxiety of parents, facilitate clinical medication, rescue medication for acute and critical patients, reduce the workload of nurses, and reduce the risk of children's anxiety. Pain, so intravenous indwelling needles are widely used clinically. Facing the special group of children, the indwelling time of intravenous indwelling needles and the comfort of children have become the most concerned issues for nurses and parents, and they are also the symbol and promotion of the successful use of indwelling needles. premise. [0003] At present, catheter materials for indwelling needles have also undergone changes from ordinary poly plasti...
