Wound monitoring method and device

Abstract

The invention discloses a wound monitoring method and device. Thus, a wound image isolated by a binding material is more suitable for being observed by human eyes and suitable for subsequent diagnosing, tracking and early warning. Wound image data is monitored through the binding material of a permeable nylon or mixed cotton fabric, a gray-level-enhanced image is obtained by preprocessing the infrared wound image through a gray level enhancing method, finally clearness treatment is conducted on the image, an algorithm is simple, the anti-noise capacity is high, fuzzy shadows generated by uneven infrared reflection can be well removed, the original style of the wound image can be well kept, the image is clearer in details, features in the image are well enhanced, the visual effect is more satisfactory, and the visual effect of the infrared image is greatly enhanced.

Description

technical field [0001] The present disclosure relates to the technical field of medical image processing, in particular to a wound monitoring method and device. Background technique [0002] Clinically, the wound healing after surgery needs to be observed every day. The conventional method is that the medical staff remove the wound dressing and observe the wound healing, disinfect the wound and replace the sterile dressing. However, there is no need to change dressings every day for primary wounds. Medical staff can only make objective judgments based on the patient's complaints, body temperature, and blood exudate contamination of external dressings when observing the wounds, which lacks intuitive judgments. Since infrared light has a longer wavelength than visible light, it can be less reflected by certain materials or textile fabrics than visible light, and can pass through the dressing material and be reflected by the wound dressing hidden under the fabric and then pass ...

Problems solved by technology

However, the first-stage wound does not need to be changed every day, and the medical staff can only make objective judgments based on the patient's complaint, body temperature, and whether the external dressing has blood exudate contamination when observing the wound, which lacks intuitive judgment.

Since infrared light has a longer wavelength than visible light, it can be less reflected by certain materials or textile fabrics than visible light, and can pass through the dressing material and be reflected by the wound dressing hidden under the fabric and then pass through the dressing material again, resulting in The infrared image of the wound, of course, not all clothes can be seen through. The pure cotton material is the safest and cannot be seen through the infrared function. Nylon and cotton blended fabrics can achieve the see-through effect, and the see-through of nylon and silk dressing materials It is as high as 75% or more. Due to the bandage material between the infrared camera and the monitored wound, the contrast of the collected wound image is blurred, making it difficult to identify the details of the monitored wound image, and the characteristic information of the wound image is very unclear.
