High-precision invasive blood pressure monitoring device

Abstract

The invention relates to a high-precision invasive blood pressure monitoring device which comprises a reflection column for being flush with the central position of the heart of a patient lying on a backboard of an operating bed in the vertical direction and a first support arranged on one side in rear of the backboard. A horizontal platform for placing an energy converter is arranged on the top of the first support, a rotating shaft is arranged on the horizontal platform vertically, the lower end of the rotating shaft is rotatably connected with the horizontal platform while the upper end ofthe same is fixed with a laser ruler capable of horizontally emitting laser, a rotating angle sensor for monitoring rotating angle of the rotating shaft is arranged on the horizontal platform, an inclination angle sensor for monitoring inclination angle when the backboard turns leftwards, rightwards, forwards and backwards is arranged at the bottom of the backboard, and the energy converter, the laser ruler, the rotating angle sensor and the inclination angle sensor are all electrically connected with a controller. The device has the advantages that by arranging the laser ruler, a reflection column, a corner sensor and the inclination sensor, height difference between the heart of a patient and the energy converter caused by bed changing can be acquired in real time by a processor throughcalculation, and a blood pressure value acquired by the energy converter is corrected to acquire an accurate blood pressure value.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to medical monitoring equipment, in particular to a high-precision invasive blood pressure monitoring device and method. Background technique [0002] Blood pressure is one of the most important vital signs of the human body. There are usually two methods of blood pressure monitoring: non-invasive blood pressure monitoring and invasive blood pressure monitoring. Non-invasive blood pressure measurement and invasive blood pressure monitoring. Non-invasive blood pressure measurement is an indirect method of measuring human blood pressure. There is a certain gap between the blood pressure measured by various non-invasive blood pressure measurement methods and the real blood pressure value of the human body. At the same time, the measurement site of non-invasive blood pressure is limited (only the arterial blood pressure of the extremities), and for critically ill patients with unstable b...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a high-precision invasive blood pressure monitoring device, aiming to solve the technical problem of inaccurate blood pressure monitoring value due to the height difference between the patient's heart and the transducer when the table top of the operating table is adjusted.
