Abstract

The invention belongs to the technical field of medical instruments and discloses a device and method for judging PICC (peripherally inserted central catheter) malposition. The method comprises: judging that a tip of a PICC enters superior vena cava by detecting continuous interruption of liquid drip. The device comprises a single-chip microcomputer, a photoelectric sensor for measuring liquid dripping speed, and an acoustic prompter for giving a prompt according to a prompt signal transmitted by the single-chip microcomputer; an I / O output end of the photoelectric sensor is electrically connected with an I / O input end of the single-chip microcomputer, and an I / O output end of the single-chip microcomputer is electrically connected with an I / O input end of the acoustic prompter; the method can conveniently and effectively judge the PICC malposition; the device is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device and a method for judging the abnormal position of a PICC catheter. Background technique [0002] With the wide application of peripherally inserted central catheter (PICC) technology in clinic, more and more attention has been paid to its related complications. Catheter malposition is a common complication of PICC and the leading cause of unplanned extubation. Ectopia can occur during and after surgery. The occurrence of intraoperative ectopy is related to the catheterization method and individual blood vessel conditions. According to research reports, the incidence of intraoperative ectopy is 12.5% ​​to 25%. At present, the conventional method for judging the abnormal position of the catheter is chest fluoroscopy or X-ray film. Usually, it is necessary to go to the relevant examination department after the catheter is placed, and then adjust it afte...
