Embodiment Construction

[0048] The working principle of the probe of the present invention is that: due to the difference in permittivity and conductivity between the wound tissue of the living body and the normal tissue near the probe, the phase change and amplitude loss of the electromagnetic field in the process of propagating between the probe feed ports are limited. different. This variability causes the instrument to measure differences in the transmission parameters of the electromagnetic field propagating between the probe feed ports. By establishing a model to extract the main analysis parameters, the database information can be compared according to these parameters, and then the information of the biological wound status can be judged.

[0049] Based on the above principles, this embodiment provides a non-invasive external trauma in vivo monitoring probe and measurement method, its structural composition and working method are as follows:

[0050] refer to figure 1 , this embodiment prov...

Abstract

The invention discloses a non-invasive monitoring probe for an in-vitro wound. The monitoring probe comprises outer-edge metallic pole plates and a medium substrate and further comprises central metallic conducting bands, wherein the outer-edge metallic pole plates are located on the medium substrate, the central metallic conducting bands are arranged on the outer-edge metallic pole plates, and gaps are reserved between the central metallic conducting bands and the outer-edge metallic pole plates; and via holes are separately formed in the two ends of each metallic conducting band, the two ends of each outer-edge metallic pole plate and the two ends of the medium substrate, so as to form coaxial-feed excitation ports. The invention further discloses an in-vitro wound monitoring method for the monitoring probe. According to the monitoring method, the probe is connected with a vector network analyzer during measuring, major parameters are extracted from measurement parameters through a specific conversion relationship and a circuit analysis model, and a state of the wound can be discriminated and analyzed based on the parameters.

Description

technical field [0001] The invention relates to the field of electromagnetic detection of biological tissue, in particular to a high-frequency (>1 GHz) electromagnetic non-invasive wound in-body monitoring probe of biological tissue and a measurement method thereof. The invention is applicable to the real-time and in-body monitoring of the wound condition outside the body. It is easy to conform, can be miniaturized, has high portability and measurement accuracy, and has a good application prospect. Background technique [0002] Wound healing is a very important and lengthy process for the injured. Monitoring the wound can not only understand the wound status in real time, and then effectively deal with it, but also provide real-time and effective information for wound assessment and treatment planning. In addition, it provides a reliable information resource for clinical research. Therefore, wound monitoring has very important application value and research significanc...
