A smart wireless sensing dressing for real-time monitoring of wound healing

Abstract

The invention discloses intelligent wireless sensing dressing capable of being used for monitoring wound surface heeling in real time. The intelligent wireless sensing dressing comprises wound surface dressing and a monitoring device, wherein the monitoring device is embedded in the wound surface dressing, is used for monitoring the temperature, the humidity, the pH value, the oxygen content, the NO (Nitrogen Oxide) concentration and microbes of the wound surface, and comprises a CPU (Central Processing Unit) control module, an input module, an output module, a Bluetooth module, sensor modules, a storage module and a power supply module; the CPU module is arranged on a flexible circuit board or an ordinary circuit board; the input module, the output module, the Bluetooth module, the sensor module, the storage module and the power supply module are interacted with the CPU control module; and the power supply module is simultaneously and electrically connected with the input module, the output module, the Bluetooth module, the storage module and various sensor modules. The intelligent wireless sensing dressing has the advantages that the wound surface information can be provided under the condition without changing the dressing; the dressing is reasonably changed according to the heeling condition of a patient; and the personalized medical care is realized, so that unnecessary waste is reduced; the pain of the patient is reduced; the wound surface heeling is accelerated; the hospital staying time of the patient is shortened; and the hospitalization expenses are reduced.

Description

【Technical field】 [0001] The invention relates to an intelligent wireless sensing dressing capable of real-time monitoring of wound healing, including sensor monitoring technology, wireless transmission technology, wearable technology, cloud storage technology, etc., and is applied in the medical field. 【Background technique】 [0002] Wound healing is a complex process that is affected by many factors throughout the healing process. Systemic factors include age, nutritional status, functional status of the blood circulation system, infection, diabetes, obesity, etc. The final manifestation of the influence of these systemic factors is the local factors of the wound, such as wound temperature, humidity, pH, bacterial infection, etc. When the parameters of these local factors are in an appropriate range, the wound will heal well. Among them, the healing process of chronic wounds is particularly complicated. The etiological mechanism of chronic wounds is complex. Through compl...

Problems solved by technology

[0004] In 2015, Petar Kassal proposed a smart bandage that can monitor the uric acid content of the wound to judge the state of the wound, but the smart bandage can only monitor one indicator of uric acid, and cannot monitor other parameters of the wound, such as temperature, humidity, pH value, oxygen content, etc.

The antibacterial effect of different pH values ​​in the local microenvironment of the wound is not exactly the same. The antibacterial effect is the best when the pH value is in an acidic environment (PH=5). As the pH value increases, the effect of inhibiting bacterial growth weakens. , when PH=7, the most suitable bacterial growth, alkaline environment can inhibit bacterial growth, but compared with acidic environment (PH=5), the ability to inhibit bacterial growth is weaker, the difference is significant (P<0.05)
