Selection method of non-intravenous injection treatment injection point

Abstract

A selection method of a non-intravenous injection treatment injection point comprises the steps: S1, using a near-infrared imaging device for imaging a to-be-injected part of a user, and obtaining a near-infrared vein image ORIGINAL of the to-be-injected part; S2, performing preprocessing such as cutting and zooming on the near-infrared vein image ORIGINAL obtained in the S1, and obtaining a gray level image GRAY; S3, carrying out gray level normalization processing on the gray level image GRAY obtained in the S2, and obtaining a normalized gray level image NORM; S4, carrying out image binarization operation on the normalized gray level image NORM obtained in the step S3 to obtain a near-infrared binary image BINARY; S5, carrying out filtering operation on the near-infrared binary image BINARY obtained in the step S4, and obtaining a vascular binary image VESSEL; and S6, acquiring candidate pixel points for the vascular binary image VESSEL obtained in the S5, respectively calculating the size of a range square of each candidate pixel point, and comparing to obtain pixel point positions corresponding to one or more specific positions most suitable for being used as injection points, thereby completing the selection of a non-intravenous injection treatment injection point.

Description

technical field [0001] The invention relates to the application of computer vision in the medical field. Background technique [0002] Injection therapy is a commonly used treatment. Depending on where the needle reaches the body tissue, injection therapy is divided into different specific treatment methods such as intradermal injection, subcutaneous injection, intramuscular injection and intravenous injection. Different injection treatment methods have different clinical applications. Injection therapy allows the drug to be absorbed faster than other treatments, resulting in faster therapeutic effects. In addition, some special drugs do not enter the human body through oral means, such as insulin, etc., they must be injected into the human body to achieve therapeutic effects. [0003] However, there are some deficiencies and shortcomings in injection therapy at present. On the one hand, current injection therapy usually requires professional medical personnel to operate...

Problems solved by technology

[0006] Aiming at the problem of injection treatment in the prior art, combined with the characteristics of near-infrared light and human tissue absorption, the present invention is based on near-infrared vein images, and is specifically aimed at non-intravenous injection treatment (that is, injection treatment including intradermal injection, subcutaneous injection, intramuscular injection, etc.) methods, but not including intravenous injection treatment), use image processing methods to find the appropriate injection point in the near-infrared vein image, realize autonomous treatment or assist medical staff in treatment, reduce the possibility of medical accidents, and improve The success rate of injection therapy makes injection therapy easier and safer
