Description

Apparatus and method for detecting skin disease symptoms

The present invention relates to the technical field of a device and method for detecting skin disease symptoms, in particular to a device that can detect potential early skin symptoms in advance, so that effective prevention and treatment can be carried out, so as to prevent the disease from being discovered until the later stage. A device and method for detecting skin symptoms that greatly increase the cure rate.

Many common diseases will show symptoms on the skin, and this kind of symptoms from the inside, when it develops under the skin in the initial stage, although it may cause slight depression or swelling on the skin surface due to inflammation and other reasons, it is due to The change is very small, and it is not easy to detect such a small change on the skin surface with the naked eye. Generally, it is usually discovered when it develops to the later stage and forms a wound on the skin. Once it develops into a wound shape, it is not only difficult to cure, but it is also susceptible to external bacterial infection and further deterioration. For example, "bedsores" usually occur on people with poor physical activity such as lying on a hospital bed or sitting for a long time and unable to move freely. They are also called pressure ulcers. The main cause is the skin and the soft tissues underneath. Long-term pressure (or compression) leads to hypoxia and necrosis of cells. Therefore, it often occurs in the protruding parts of bones (such as buttocks, back, sacrum, seat bones, heels, etc.). When these parts are under pressure for a long time, When the blood circulation of the tiny blood vessels under the skin is blocked, the compressed part cannot get enough nutrition, so it will cause local skin tissue damage and enter And gradually form bedsores. Therefore, in the early stage of occurrence, bedsores cannot be seen with the naked eye from the surface of the skin. Once they develop to a later detectable wound state, it is not only difficult to cure, but also susceptible to bacterial infection and further deterioration. According to medical statistics, if bed sores cannot be controlled and healed in time, the fatality rate will exceed 50% within half a year, and no more than 20% will survive one year.

Therefore, how to detect the skin disease in the early stage when the skin disease is not manifested, and enable effective prevention and treatment in advance, so as to prevent the disease from being discovered until the later stage, is a topic that needs to be solved urgently.

The main purpose of the present invention is to solve the problem that the conventional skin disease cannot be seen from the surface of the skin with the naked eye in the early stage of occurrence, and it is often discovered when it develops to the later stage and forms a wound shape, which makes it difficult to cure and susceptible to bacterial infection. Problems such as further deterioration.

The present invention provides a device for detecting skin disease symptoms, which includes an optical detecting instrument and a processing device. Among them, the optical detection instrument can capture skin texture images of specific parts of the human body. The processing device can store the time, location and image information of each skin texture image captured, and calculate and compare the skin texture density in the previous and previous captured skin texture image information for the same part, and then determine whether there is any For abnormal changes that exceed the preset range, when it is determined that the skin texture density has abnormal changes, a warning signal is displayed to remind the medical care personnel to take corresponding treatment.

The present invention provides a method for detecting skin symptoms, including (a) Capture skin texture images of specific parts of the human body at intervals; (b) Store the time, location and image information of each captured skin texture image; (c) Perform Gaussian filtering on each skin texture image to obtain a clear Skin texture; (d) Use the Canney edge calculation method to obtain whether there are any abnormal changes in the density of the skin texture captured before and after; (e) Compare and determine whether the skin texture has abnormal changes; and (f) When judging the texture density of the skin When there is an abnormal change, a warning signal is issued.

The device and method for detecting skin symptoms provided by the present invention can use the optical detection instrument to capture skin texture images of a specific part of the human body at different times, and then use the processing device to calculate and compare the previous and previous captured images of the same part Take the skin texture density of the image and determine whether it has abnormal changes that exceed the preset range. When it is determined that the skin texture density has abnormal changes, a warning signal is displayed to remind the medical care staff to take corresponding treatments. The potential early symptoms of the skin can be detected in advance, so that effective prevention and treatment can be carried out to prevent the disease from being discovered until the later stage, so as to greatly increase the cure rate.
