Polarized skin lens

Abstract

The invention discloses a polarized skin lens, which can be applied for observing the deep-layer fine structure of a skin pigment damaging part directly, and does not need an infiltrated liquid. The polarized skin lens provided by the invention comprises a lens base, a lens group and a ring-shaped light source, wherein the lens group is arranged in the lens base; the ring-shaped light source is arranged at the periphery of the lens base; the lens group comprises at least two lenses; the polarized skin lens also comprises a first polarized sheet arranged in the lens base, and a ring-shaped second polarized sheet arranged at the periphery of the lens base; the first polarized sheet is arranged between the lenses of the lens group; the second polarized sheet is arranged between the ring-shaped light source and a skin sample to be tested; and the second polarized sheet and the first polarized sheet are vertical on the polarization direction. The polarized skin lens does not need the infiltrated liquid, and has the characteristics of being small, convenient and simple and being easy in operation.

Description

technical field [0001] The invention relates to a dermatoscope, in particular to a polarized dermatoscope. Background technique [0002] The skin is the largest organ of the human body. It is mainly responsible for the isolation and communication between the inside and outside of the human body, and has the functions of protecting the internal environment, sweating and feeling external stimuli. Skin diseases can bring itching, pain and various cosmetic problems to patients, seriously affecting the physical and mental health of patients, and even affecting the lives of patients. In recent years, the incidence of skin cancer has shown a gradual upward trend. Therefore, the development of tools for assisting the diagnosis of skin pigmented lesions is very necessary. [0003] At present, the diagnosis of skin diseases mainly depends on clinical manifestations and histopathological examination. Skin histopathological examination is the basis for deeply exploring the occurrenc...

AI Technical Summary

Problems solved by technology

During observation, the lens directly contacts the skin, and requires infiltration fluid, artificially squeezed on the skin, not suitable for the head and face, especially in mucous membranes such as the mouth, eyes and nose, and image observation of sensitive skin

Moreover, when the traditional infiltration method is used for observation, the lens directly contacts the skin to cause extrusion deformation, and the required infiltration solution as the infiltration solution will cause contact dermatitis, and there are potential risks such as iatrogenic cross-infection

Therefore, so far, there is still a blank in the domestic field of dermoscopic products that are practical, convenient, and do not require an infiltration solution.
