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...

Examples

Embodiment 1

[0033] Such as Figure 1~4 As shown, a special infusion set for indwelling catheters is composed of an infusion set 1 containing simple infusion or other performances and a positive pressure set 2 with antithrombotic performance. The infusion set 1 does not have an infusion needle and can be used for clinical infusion Or on this basis, a complete infusion set with other performances is attached, the end of which is an external conical infusion connector 11, and the positive pressure component 2 is arranged at the end of the infusion component 1 and connected with the infusion connector 11, which is a part of the infusion channel. It is a device that has positive pressure performance and utilizes the medicinal liquid remaining in the cavity to realize long-acting micro-volume slow-release infusion. Switching assembly, wherein the rear joint 21 is connected to the infusion joint 11 of the infusion set 1, and the front joint 22 is an outer conical joint connected to the indwellin...
