Problems solved by technology

Because the collected voltage signals are all on the millivolt level, the collected signal data is extremely susceptible to electromagnetic interference (such as static discharge, electrical fast bursts), which in turn affects the accuracy of the signal

Abstract

The invention provides a portable liver reserve function detection device. The portable liver reserve function detection device comprises a computer, a detector and fingers of a patient to be detected, the computer is provided with a Bluetooth receiving module, and the detector comprises a first circuit board and a second circuit board; the first circuit board and the second circuit board are connected through a data line and are symmetrically mounted in the upper supporting part and the lower supporting part of the detector respectively; a light source is arranged below the first circuit board, and a Bluetooth transmitting module and a photoelectric receiver are respectively arranged above the second circuit board; a finger of a patient to be detected is placed in the detector, the first circuit board controls the light source to emit a light signal, the Bluetooth emission module transmits a digital signal to the Bluetooth receiving module, and the plasma clearance rate and the ICG retention rate are calculated through the computer. According to the invention, non-invasive measurement is realized, the detection precision is improved, the stability is enhanced, the cost is low, and large-area popularization of the liver reserve function detection instrument in clinical use is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a portable liver reserve function detection device and a detection method thereof. Background technique [0002] The detection principle of the liver reserve function testing equipment is: using indocyanine green ICG indicator for concentration dilution and excretion test of pigment concentration measurement method, which is a commonly used method of liver reserve function detection technology in clinical medicine at home and abroad. ICG can quickly combine with plasma proteins after being injected into the blood through veins, and distributes throughout the body with arterial blood, and is only absorbed by liver cells and excreted into bile. Its concentration in blood decreases exponentially, and the slope of the downward trend is the plasma clearance rate. K( / min), it represents the rate of decrease of ICG concentration in the blood per minute, and the plasma clearanc...
