Problems solved by technology

[0002] Among the existing technologies, the more mature technology is to detect the content of free hemoglobin in blood bags through chemical testing, which has the outstanding advantage of high accuracy, but the method of chemical testing cannot meet the needs of fast, non-contact, and pollution-free. Due to its non-contact and pollution-free characteristics, spectroscopic measurement may also detect the content of free hemoglobin in blood bags
[0003] In view of the complexity of blood components, the pure transmission spectrum obtains the information of whole blood, which is poor in pertinence. In order to further improve the measurement accuracy of free hemoglobin, combined with the strong pertinence of fluorescence, but affected by the strong scattering of blood, Therefore, it cannot reflect the characteristics of the measured substance very well.

Embodiment 3

[0066] In actual implementation, due to the limitation of the space structure, it may occur that the light source 1 and the spectrum receiving device 5 cannot be close to the blood bag 3. At this time, an optical fiber can be respectively arranged at the light source 1 and the spectrum receiving device 5 as the incident optical fiber 2 and outgoing fiber 6.

[0067] see image 3 , the light source 1 transmits and excites the blood sample in the blood bag 3 through the incident optical fiber 2, and the spectrum receiving device 5 collects the transmission spectrum and the fluorescence spectrum through the outgoing optical fiber 6, and the incident optical fiber 2 and the outgoing optical fiber 6 are respectively close to the blood bag 3, Position a is the first position of the incident optical fiber 2, and the spectrum receiving device 5 collects the transmission spectrum and the fluorescence spectrum at this position; the incident optical fiber 2 is controlled by the displacem...
