Probe for synchronous multi-point measurement of arterial plane pressure waves

Abstract

The invention discloses a probe for synchronous multi-point measurement of arterial plane pressure waves. The probe comprises a probe shell and measuring probes, wherein the probe shell comprises a first shell body and a second shell body, one side of the first shell body and one side of the second shell body are connected with the measuring probes respectively, the side face of the first shell body and the side face of the second shell body are connected with the measuring probes through threaded holes respectively, and a circuit board in the first shell body and a circuit board in the secondshell body are connected with the measuring probes through transmission lines respectively. During measurement, a mounting plate moves on the outside of the body, and rollers can move along with themounting plate on the outside of the body, which reduces the friction force during movement and can have a supporting effect on the measuring probes, so that the measuring probes are in even contact with the body, and the measurement effect is better. During measurement, the mounting plate is pressed downward, so that when the pressure between the measuring probes and the body is increased, forcebearing points of the body are increased, which cannot make the body damaged. When the pressured is decreased, damping springs push threaded cylinders and threaded rods to move outward from the innerportions of loading holes, so that the use is convenient and quick.

Description

technical field [0001] The invention relates to a measuring probe, in particular to a probe for synchronous multi-point measurement of arterial plane pressure waves, which belongs to the application field of medical probes. Background technique [0002] Since arterial vessels are not homogeneous, compliance varies in different parts of the same vessel. Simultaneously measuring the diameter of a section of arterial vessel and the blood pressure in that region allows direct calculation of local arterial compliance. Blood vessel diameter can be measured using ultrasound or MRI. In order to accurately measure the expansion pressure of blood vessels, at present, sufficient measurements are usually performed at the same site to improve accuracy. [0003] Most of the existing arterial plane pressure wave synchronous measurement probes are single, and when measuring outside the patient's body, only one point can be measured at a time, the measured data is limited, the accuracy is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a probe for synchronous multi-point measurement of arterial plane pressure wave, which can solve the problem that most of the existing arterial plane pressure wave synchronous measurement probes are single, and when measuring outside the patient's body, only one point can be measured at a time. The measured data is limited, the accuracy is not enough, and the measurement effect is not good

During the measurement process, the contact comfort between the patient's body and the probe is not high, and the parts where the probe is installed cannot be adjusted according to the size of the patient's body, which is a technical problem with large limitations
