Medical catheter indwelling device

Abstract

The invention provides a medical catheter indwelling device, and belongs to the field of manufacturing of medical supplies. The device comprises a shell, a puncture needle, a guide wire and a catheter, the puncture needle is fixed in the shell and extends out of the puncture end; the guide wire is slidably located in the puncture needle, and the catheter is arranged on the outer side of the puncture needle in a sleeving mode. A slidable push button is arranged on the shell, and the tail part of the guide wire is fixed on the push button; the push button slides towards the puncture end relative to the shell, so that the guide wire slides out towards the puncture end along the puncture needle; a slidable push rod is further installed on the shell, and the guide pipe is clamped on the push rod. The push rod slides towards the puncture end relative to the shell, so that the catheter slides to the guide wire from the puncture needle. The puncture needle is fixed to the shell, the guide wire is inserted into the guide wire through the slidable push button, the catheter slides to the embedded guide wire from the puncture needle through the push rod, and therefore the placement work of the catheter is completed; the guide wire, the catheter and the puncture needle are effectively integrated on the same shell, the two hands are liberated to the maximum extent, and therefore operation is easier and more convenient.

Description

technical field [0001] The invention relates to medical device manufacturing technology, in particular to a medical catheter insertion device, which belongs to the technical field of medical product manufacturing. Background technique [0002] With the continuous development of infusion tools, peripheral venous catheters, medium length catheters (MC), central venous catheters (CVC), peripherally inserted central catheters (PICC) and infusion ports (PORT) are widely used in clinical practice. . Compared with several other infusion methods, the medium-length catheter has the advantages of fast puncture speed, high safety, and low maintenance cost, and provides an economical and safe intravenous infusion method for patients. Midline catheters are divided into common types of 20-30 cm and mini-types of 8-10 cm. Mini-type midline catheters are mostly used to replace indwelling needles. [0003] The midline catheter is suitable for patients with an estimated treatment time of 1 ...
