Invasive arterial blood pressure monitoring device

Abstract

The invention discloses an invasive arterial blood pressure monitoring device. The invasive arterial blood pressure monitoring device comprises a pressure connecting pipe filled with a pipe flushing liquid and provided with a switch, a continuous flushing system and an electronic monitor, wherein one end of the pressure connecting pipe is connected with an artery puncture needle, and the other end of the pressure connecting pipe is connected with the electronic monitor; a three-way joint A, a liquid extracting device and a transducer are sequentially arranged from the end, connected with the artery puncture needle, of the pressure connecting pipe to the end, connected with the electronic monitor, of the pressure connecting pipe; and the transducer is connected with a pressurizing bag. When the invasive arterial blood pressure monitoring device is used for invasive arterial blood pressure monitoring, according to arterial blood pressure waveforms on the electronic monitor, digital guidance of operation can be realized, and whether the artery puncture needle punctures in place is judged, so that the puncture success rate is improved and the puncture time is shortened.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an invasive arterial pressure monitoring device. 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 patient. [0003] In the prior...

AI Technical Summary

Problems solved by technology

Existing arterial puncture needles rely entirely on experience to operate. In the process of puncture, it is difficult to grasp whether the puncture is in place or successful; the success rate of arterial puncture is not as high as the improved one, and the success rate is only about 80%. in 9~10min
