Monitoring system and monitoring method capable of collecting high-quality plasma

Abstract

The invention relates to a monitoring system and a monitoring method capable of high-quality collection of blood plasma. A technical scheme in the invention is as follows: the monitoring system comprises a blood inductor; a photoelectric induction part comprises a photoelectric amplifier and an optical fiber probe; the photoelectric amplifier can emit a three-primary-color hybrid light source which irradiates on to-be-tested blood plasma through the optical fiber probe; a reflected light source can be conducted to the photoelectric amplifier through the optical fiber probe for calculation, chromatic aberration changes are automatically analyzed and processed based on a diffuse reflection light source, chromatic aberration change jumping is carried out according to changing conditions of the light sources, and calculation results are fed back to a master control system through a TTL level; blood plasma and erythrocytes are judged through spectral wavelengths (of three primary colors consisting of a red color, a green color and a blue color), i.e., through wavelengths; changes of wavelengths are analyzed based on received reflected (scattered) light, so a medium is determined, thereby realizing determination of the amount of erythrocytes in blood plasma. The invention has the following beneficial effects: the problems of great external interference in separation of blood plasma, poor stability and great possibility of a failure in monitoring of erythrocytes are overcome, and collection of useless components in platelets and erythrocytes is prevented.

Description

Technical field: [0001] The invention relates to a medical device for plasma collection and a monitoring method during collection, in particular to a monitoring system and a monitoring method capable of collecting high-quality plasma. Background technique: [0002] At present, domestic centrifugal blood component separators have a single function in the monitoring of blood components. Blood sensors (visible light direct-radiation type) are generally used in the monitoring of red blood cells to identify changes in plasma night color, which is subject to large external interference, poor stability, and easy to cause damage to red blood cells. Failure to monitor directly affects the quality of plasma collection. Invention content: [0003] Purpose of the invention: [0004] In order to provide a monitoring system and a monitoring method capable of collecting high-quality plasma that can perform double monitoring, improve monitoring effect and precision, and determine the pla...
