Dermatoscope capable of detecting bloodstream

Abstract

The invention provides a dermatoscope capable of detecting bloodstream. The dermatoscope comprises a dermatoscope probe and a processing unit connected to the dermatoscope probe, the dermatoscope probe comprises a light source component, first polarizing film located in front of the light source component and an imaging optical path arranged next to the light source component, the imaging optical path comprises second polarizing film and an imaging component, the imaging component comprises an imaging lens, a filter switch device and a photoelectric detection chip, the light source component comprises the two light sources of a broadband spectrum light source and a laser light source, the broadband spectrum light source is used for the dermatoscope probe to obtain skin morphology information, the laser light source is used for the dermatoscope probe to obtain a laser speckle image to detect skin bloodstream information, and the combination of the skin morphology information and the skin bloodstream information can synchronously provide structure information and function information of skin. The dermatoscope capable of detecting bloodstream not only is applied to skin disease diagnosis, bu also has an important effect on therapeutic effect evaluation.

Description

technical field [0001] The invention relates to a dermatoscope, in particular to a dermatoscope capable of detecting blood flow. Background technique [0002] The skin is the first line of defense of the human body, protecting internal tissues and organs from various mechanical, chemical, pathogenic microorganisms and other hazards. In recent years, with the continuous escalation of food safety and environmental problems, the health, life safety and psychological problems of patients caused by skin diseases have attracted more and more attention from the society; at the same time, skin diseases are also the most diverse diseases; and the current diagnosis of skin diseases is mainly based on Clinical manifestations and histopathological examination, the former depends on the doctor's clinical experience and has a subjective component, while the latter is an invasive test, which can lead to serious consequences such as the metastasis of malignant melanoma in severe cases. It ...

Problems solved by technology

Laser speckle blood flow imaging technology or laser Doppler technology is an emerging means of detection and imaging of blood flow signals in recent years, both of which have the advantages of non-contact, non-invasive, and no need for contrast agents. Field blood flow imaging, the time resolution can reach tens of milliseconds, and the spatial resolution can reach microns. Because of its non-invasive and real-time performance, it has been popular in clinical detection in recent years, but there is no blood flow imaging technology currently available. Dermoscopy devices with detection functions, such as: the invention patent "Polarized Dermatoscope" with application number 201010178190.8, which only observes the microstructure information of skin damage; Different methods are used to observe the structural information of the skin surface and below the cutin of the skin. The above-mentioned patents only observe the structural information and do not have the functional information of observing the blood flow.
