Abstract

The invention provides a wound surface monitoring device. The wound surface monitoring device comprises a flexible substrate, a lead wire arranged on the surface of the flexible substrate, and at least one sensor which is arranged on the surface of the flexible substrate and is connected with the lead wire; the flexible substrate is provided with at least one vent hole; and the sensor is used formonitoring information, wherein the information comprises the temperature, the humidity, the pH value, the electrical impedance and the pressure of a wound surface. The wound surface monitoring deviceprovided by the invention can carry out multi-position integrated real-time monitoring on healing and infection conditions of the wound surface, and is beneficial to healing of the wound surface. Meanwhile, the flexible substrate is provided with the vent holes, so that ventilation and liquid permeability of the wound surface monitoring device are facilitated, healing of the wound surface is further promoted, and wound surface infection is prevented. Moreover, flexibility of the wound surface monitoring device is improved, and then the wound surface monitoring device can be well attached to the wound surface, so that monitoring on the wound surface is facilitated, and thus a monitoring result is more accurate and reliable. The invention also provides a preparation method of the wound surface monitoring device and a wound surface dressing component comprising the wound surface monitoring device.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a wound monitoring device, a preparation method thereof, and a wound dressing assembly. Background technique [0002] The traditional wound monitoring method is mainly to observe with the naked eye and make judgments based on the physical and chemical forms of wound tissue. Wound healing is a complex process, and many factors can directly or indirectly affect the healing. At the same time, the understanding and control of wound infection also play a very important role in promoting wound healing. Monitoring only through naked eye observation needs to rely on the medical experience of the observer, which has low accuracy and is easily affected by subjective effects, and cannot accurately and objectively reflect the status of wound healing and infection. Contents of the invention [0003] In order to solve the above problems, this application provides a wound monitoring device,...
