Wound detection system based on ultrasonic technology

Abstract

The invention discloses a wound detection system based on an ultrasonic technology. A control module controls the output frequency, a local oscillation module generates an oscillation current signal according to the output frequency provided by the control module, an amplification module amplifies the oscillation current signal, an energy converter converts amplified oscillation current into mechanical energy, a receiving probe receives reflected back ultrasonic waves, a scanning module converts an ultrasonic wave signal received by the receiving probe into a pulse electric signal, and an oscilloscope displays the pulse electric signal converted by the scanning module and the oscillation current signal amplified by the amplification module. According to the wound detection system based on the ultrasonic technology, through the arrangement of the modules, the wound depth can be detected without extending into a wound, the pain of a wounded person cannot be caused, the healing wound cannot be influenced, and the detection system is beneficial for wound healing.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wound detection system based on ultrasonic technology. Background technique [0002] Wound measurement parameters can provide objective data to predict changes in wound prognosis for exudate, necrotic tissue, slough, granulation tissue, undermining, and sinus tracts. According to relevant studies, it has been confirmed that the reduction in wound size within the first two to four weeks of treatment is significant. Statistically significant independent factors predicting wound healing. [0003] The depth of the wound is the depth perpendicular to the skin surface with the deepest part of the wound as the bottom. The current measurement of wound depth is to put a sterile fine cotton swab into the deepest part of the wound perpendicular to the wound surface, then make the tweezers flush with the wound surface to clamp the cotton swab, take out the cotton swab, and measure the len...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing wound depth detection method is easy to cause pain for the wounded, and at the same time, for the healing wound, the tissue at the wound will be destroyed, which is not conducive to wound healing. Wound detection system to solve the above problems
