Infusion apparatus special for indwelling catheter

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and discloses an infusion apparatus special for an indwelling catheter. The infusion apparatus is composed of an infusion assembly and a positive pressure assembly, wherein the infusion assembly has the pure infusion performance or additional other performances, and the positive pressure assembly has the thrombus preventing performance. When connected with an indwelling needle for infusion and disengaged from the infusion apparatus at the end of infusion, the positive pressure assembly can be separated from the infusion assembly and can indwell on the indwelling catheter, long-acting micro slow-release infusion is achieved by means of liquid medicine left over in a positive pressure cavity of the positive pressure assembly, the indwelling catheter is made to maintain positive pressure for a long time, blood backflow can be effectively prevented, and the problem that indwelling catheter coagulation or thrombus blockage can be effectively prevented in a long-acting mode. By the adoption of the infusion apparatus, the indwelling positive pressure assembly is detached to be discarded before next infusion is carried out, and then a new infusion apparatus is connected to the indwelling catheter to be used.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a special infusion set for indwelling catheters used to prevent blood reflux and thrombus formation during indwelling catheters for infusion in blood vessels. infusion set. Background technique [0002] The infusion set is an irreplaceable broad-spectrum diagnosis and treatment method for clinical infusion. Its technological development has made major breakthroughs in recent years. On the basis of special features such as precision filtration, light protection, and sub-packaging, it has also developed automatic exhaust technology and automatic stop. Infusion technology and other safety models that get rid of the dependence on the experience of nursing staff have made great progress, but as a special infusion set for use with indwelling needles, it is a blank. At present, the indwelling needle is advocating steel-free infusion for occupational safety in the world...
