Camera-based plasma chyle and hemolysis detection device and method

Abstract

The invention discloses a camera-based plasma chyle and hemolysis detection device and method. The method comprises steps: blood or plasma image information in a sample test tube stored in a test tubegrid is taken through the camera; based on the image taken by the camera, a plasma chyle degree and hemolysis degree detection result is generated through a signal processing system; corresponding control signals are triggered, and the control signals are then sent to a motor; the motor rotates according to the control signals of the signal processing system, and the amplitude of rotating drivesthe rotating turn number of a corresponding power wheel; the information of a test tube in a test tube grid, the chyle degree and hemolysis degree detection result of the plasma in the test tube and the control signals of the signal processing system are stored by a storage device; and a power supply provides working power for the camera, the storage device, the signal processing system and the motor. The device and the method disclosed in the invention are high in accuracy and 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 camera-based plasma chyle and hemolysis detection device and method. 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 necessary to observe a...

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 blood volume collected in different clinical trials is not necessarily the same, so the blood level 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 distinguish the degree of hemolysis and chyle by observing the color of plasma with the naked eye of medical staff. higher rate
