Abstract

The invention provides a nail growth detector and a detection method. The detector comprises a fixing device used for correcting the posture of a finger to be measured, an image acquiring device and an image analyzing device, wherein the image acquiring device is adjacent to the fixing device, and connected with the image analyzing device in data communication. The image acquiring device is used for collecting a finger image of the finger to be measured fixedly placed at the fixing device, and sending the finger image to the image analyzing device. The image analyzing device obtains a reference point and a moving point from the finger image, and the distance between the reference point and the moving point is calculated to obtain a measured value. The nail growth detector and the detection method disclosed by the invention can fast and accurately obtain the nail growth conditions to greatly reduce the difficulty of nail measurement.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a nail growth detector and a detection method. Background technique [0002] Nails are specialized skin appendages with fixed morphology, constant growth direction and growth rate. Nail growth depends on the continuous proliferation and keratinization of nail matrix keratinocytes, which belong to early response tissues. Nail radiation reactions can be observed shortly after radiation exposure. The changes before and after the control nail irradiation, especially the growth velocity, should be able to predict the sensitivity of the normal tissue of the patient, especially the early response tissue. At present, nail growth is mostly measured with a vernier caliper as a tool. Select two measuring points on the finger, use the vernier caliper to measure the distance between the two points, after a certain time interval, measure the distance between the two measuring points again. ...
