Puncture method of artery puncture needle for invasive arterial blood pressure monitoring

Abstract

The invention discloses a puncture method of an artery puncture needle for invasive arterial blood pressure monitoring. The puncture method is characterized by comprising the following steps: (1) preparing materials; (2) connecting an invasive arterial blood pressure monitoring device; (3) checking whether the invasive arterial blood pressure monitoring device is normally connected; (4) determining an artery pulsation point; (5) disinfecting the skin; (6) puncturing; (7) judging whether the puncture is successful; and (8) extracting a steel needle after successful puncture, sending a soft needle to a vessel position, and finally fixing an artery puncture needle. The puncture method can realize digitized guidance of operation through arterial blood pressure waveforms on a monitor and judge whether puncture of the artery puncture needle is in place according to the arterial blood pressure waveforms on the monitor; and the whole puncture process is performed in a closed manner, so that blood overflow is prevented, puncture points are protected against contamination, the puncture success rate is high, and the puncture time is short.

Description

technical field [0001] The invention belongs to the technical field of medical care and relates to a puncturing method of an arterial puncture needle for invasive arterial pressure monitoring. Background technique [0002] Invasive arterial pressure monitoring is to puncture and place a catheter in the peripheral artery, and connect the pressure sensor to the monitor to reflect the blood pressure changes in each cardiac cycle, which can directly display systolic blood pressure, diastolic blood pressure and mean arterial pressure. Invasive arterial pressure monitoring has the advantages of not being affected by external factors such as artificial pressure, decompression, cuff looseness and tightness, etc., and can accurately and intuitively detect instantaneous changes in arterial blood pressure in a timely manner, and can take arterial blood for analysis, reducing the risk of repeated punctures. It relieves the pain of the patient and wins precious time for rescuing the pati...

AI Technical Summary

Problems solved by technology

Arterial needle puncture is operated entirely by experience, and it is difficult to determine whether the puncture is in place or successful during the puncture process; the success rate of arterial puncture is not as high as that of the improved one, and the success rate is only about 80%, and the arterial puncture takes a long time, averaging 9 ~10min
