Apparatus and method for detecting plasma chyle and hemolysis suitable for multi-standard test tubes

Abstract

The invention discloses a detection device and method for plasma chyle and hemolysis suitable for multi-standard test tubes. The method includes: acquiring in real time the color sensing signal of the blood sample placed in the test tube in the test tube through a color sensor; according to the blood color sensing signal, through The signal processing system triggers the corresponding control signal, and sends the control signal to the motor; the motor rotates according to the control signal of the signal processing system, and then drives the power wheel to rotate the corresponding number of turns, so as to realize the height position adjustment of the color sensor; Provide working power signal for signal processing system, motor and color sensor through power supply. The detection result of the invention has high accuracy and high practicability, and can be widely used in the technical field of medical equipment.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a detection device and method for plasma chyle and hemolysis in multi-standard test tubes. Background technique [0002] In clinical trials, due to excessive negative pressure during blood collection, excessive shaking, and high fragility of the red blood cells of the subjects, the red blood cells in the collected blood samples rupture and undergo hemolysis. The substance in the plasma enters the plasma, and the plasma is light red, which affects the accuracy of clinical blood samples; when the subject suffers from hyperlipidemia, eats a large amount of fatty food or other reasons, the plasma contains a large number of chylomicrons, forming chylomicrons. At this time, the subject’s plasma color is milky white. When the subject develops chyle blood, it will affect the concentration detection of fat-soluble drugs. Therefore, after the blood sample is centrifuged, it is ne...

Problems solved by technology

[0003] In the process of collecting blood samples, different subjects may use test tubes of different specifications to collect, and the amount of blood collected for the test items is not necessarily the same, so the height of the blood collected in each collection test tube is not uniform. It is obviously not practical to use a device with a fixed height to obtain the blood status in test tubes of different specifications. The existing methods generally use the naked eyes of medical staff to observe the color of plasma to distinguish the degree of hemolysis and chyle. However, this method of subjective judgment has a high error rate higher
