Description

An intelligent analyzer for wound outcome

technical field

The invention relates to the technical field of wound measurement and analysis, in particular to an intelligent analyzer for wound outcome.

Background technique

In surgical diseases, the diagnosis and treatment of acute and chronic wounds has long been a crucial part of clinical work. Therefore, rapid diagnosis and measurement of acute and chronic wounds are important for patient treatment, refined wound management, disease supervision, and wound prognosis. Judgment plays a very important role. Not only that, the accurate measurement and calculation of the wound area is also very important for clinical researchers to judge the situation of drugs promoting wound healing in clinical experiments or to judge the role of a new tissue engineering material on wound healing. With the progress of society and the development of science and technology, many emerging measurement technologies have gradually emerged. In addition to the most primitive direct measurement method with rulers, medical workers can also use methods such as grid transparent film to trace the wound boundary to measure the wound area. The wound area can also be calculated according to the pixel principle after taking pictures with a digital camera. Due to the difference in the cause of injury, the difference in the injury site and the individual differences of each injured patient, the wound of each patient or different wounds of the same patient shows individual appearance, size, volume, depth and other aspects. make differences.
