Double-tracer detection device and method capable of simultaneously detecting ICG (indocyanine green) and methylene blue

Abstract

The invention discloses a double-tracer detection device capable of simultaneously detecting ICG (indocyanine green) and methylene blue. The detection device comprises a host machine, a light source transmitter, an optical system, an image pickup system, a computer processing system and a display system, wherein a controller is arranged in the host machine; and the light source transmitter, under the control of the controller, can transmit light which are in two wavelengths, namely 660nm and 785nm. By virtue of the controller, power of the light source transmitter can be changed. The optical system is a double-wavelength optical system and can enable light of 690nm and 815nm to pass through and screen spectra of other wavelengths. Meanwhile, the invention also discloses a detection method which makes use of the device; the method, which implements tracking on the basis of fluorescence characteristics of the methylene blue, not only achieves independent display of ICG and methylene blue fluorescent light but also achieves simultaneous display of the ICG and methylene blue fluorescent light; and the detection rate is improved.

Description

technical field [0001] The invention relates to a trace display method and device applied in the medical field, in particular to a dual trace detection device and method capable of simultaneously detecting ICG and methylene blue. Background technique [0002] Both ICG and methylene blue are currently commonly used tracer drugs in clinical practice. Among them, ICG uses its fluorescence characteristics for tracing, and methylene blue uses the color of methylene blue for detection and tracing. [0003] After ICG enters the human body, it will combine with albumin in the body to form a substance with a large molecular weight. Due to the large molecular weight of this substance, it diffuses slowly during the tracing process. When encountering lymphatic or vascular pathology In the case of sexual blockage, this substance cannot even pass. [0004] After entering the human body, methylene blue will not combine with substances in the human body, and will maintain its good small mo...

Problems solved by technology

[0006] Although methylene blue has good penetrability, since the traditional tracer method is to trace by observing the color of methylene blue, it requires a higher concentration of methylene blue

In the actual use process, as the methylene blue enters the depth of the human body, the concentration of methylene blue will gradually decrease, so in the process of use, sometimes the concentration will decrease and the color will become lighter and the detection will be missed.

[0007] In addition, since the human body has different absorption rates for ICG and methylene blue, although the traditional tracer method is to inject ICG and methylene blue into the human body at the same time, since ICG uses its fluorescence properties for tracer, methylene blue Blue is to use the color of methylene blue for detection and tracing, so it cannot be displayed at the same time, and the detection rate is low
