Problems solved by technology

[0002] During infusion, it is often necessary to indwell the human body for infusion. The use of indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections, reduce the anxiety of parents, and facilitate clinical medication; After the infusion needle is pulled out, there will be a period of drug liquid reflux after the indwelling needle is pulled out of the catheter hub, and blood reflux often occurs, forming a thrombus and affecting the next infusion; therefore, it is necessary to provide a method that can prevent the formation of Indwelling needle for thrombus

Abstract

The invention relates to the technical field of medical apparatuses, in particular to a pushing and pulling type anti-thrombus remaining needle. The pushing and pulling type anti-thrombus remaining needle comprises a Y-shaped three-way connecting base, the Y-shaped three-way connecting base is internally provided with a drainage tube, a heparin cap is installed at the inlet end of the drainage tube, an infusion tube is connected to the outlet end of the drainage tube, and a catheter base is connected to the tail end of the infusion tube; the heparin cap is provided with an extending tube usedfor generating positive pressure for the drainage tube, the extending tube is connected in the drainage tube in a sleeving mode, slidably abuts against the drainage tube and is communicated with the drainage tube; an adjustable flow liquid stopping clamp is installed between the Y-shaped three-way connecting base and the catheter base and is arranged on the infusion tube. The positive pressure isgenerated by pushing and pulling the heparin cap, then it is avoided that thrombi are formed in the remaining needle, and the extending tube and the drainage tube are directly matched, the pushing andpulling type anti-thrombus remaining needle is simple in structure and reasonable in design.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a push-pull antithrombotic indwelling needle. Background technique [0002] During infusion, it is often necessary to indwell the human body for infusion. The use of indwelling needles can reduce the pain caused by repeated venipuncture and the fear of injections, reduce the anxiety of parents, and facilitate clinical medication; After the infusion needle is pulled out, there will be a period of drug liquid reflux after the indwelling needle is pulled out of the catheter hub, and blood reflux often occurs, forming a thrombus and affecting the next infusion; therefore, it is necessary to provide a method that can prevent the formation of Indwelling needle for thrombus. Contents of the invention [0003] The present invention provides a push-pull antithrombotic indwelling needle aimed at the problems of the prior art, which has a simple structure and a reasonable desig...
