Description
Technical field
The invention belongs to software-hardware synergism field of medical technology, and in particular to a kind of electronics skin monitored in real time for wound
Skin.
Background technology
In recent years, soft electronic industry development is swift and violent, is got in the performance of the industries such as flexible screen, flexible battery, flexible sensor
Carry out bigger effect.But soft electronics permeates still inadequate in medical field.Medical field is due to its particularity, for soft material
Expect, the bio-compatibility of material has tightened up demand.On the other hand, in terms of specific to wound monitoring, traditional wound prison
Survey method mainly relies on unaided eye discrimination wound situation, more more complicated, is that extraction wound surface body fluid is further managed
Change detection.The former needs to rely on medical experience, and poor accuracy, easily by subjective impact, then flow is complicated by the latter, somewhat expensive, also
Pain may be brought to patient.Since the poor accuracy either flow of said program is complicated, lead to not carry out wound real
When monitoring, optimal processing can not be carried out to wound on optimal opportunity, therefore to the real-time monitoring system of wound
Demand is objective reality and urgent.
Traditional wound monitoring method is exactly mainly to take away bandage to observe wound, is sentenced according to the physics and chemistry form of wound tissue
Its disconnected healing situation.On the one hand, it if wound does not heal also, is likely to that wound is made to be infected in this way, leaving can not smear
The scar fallen increases patient suffering；On the other hand, the conclusion obtained is observed by the naked eye to need to rely on medical experience, accuracy
Difference easily by subjective impact, and can only obtain qualitative conclusions.
More complicated monitoring method is then that extraction wound surface body fluid carries out further Physico-chemical tests.For example, in the recent period
One of Melissa L Fernande etc. has found the uric acid content in detection wound exudate for the research of Venous Ulcers
Contribute to the severity of differentiation wound.Uric acid can deposit sodium urate crystals (Monosodium urate in wound
Crystal) cause inflammatory reaction, to inhibit wound healing.By detecting the composition of wound exudate, researcher has found when urine
When sour water is flat higher, wound is more serious, and healing time is also longer.Researcher thinks can be by monitoring in wound exudate
Uric acid or a variety of uric acid precursor levels differentiate the severity with predicted wound, have certain diagnostic value.Uric acid level
Raising be often proportionate with wound seriousness, and the raising of uric acid precursor such as purine level show wound severity compared with
It is low.Therefore the purine metabolism variation in monitoring wound exudate will be seen that the healing of chronic wounds such as Venous Ulcers etc.
Journey.In addition, Harvard Medical School's professor's Kang Na L Evans has developed a kind of bandage.This bandage adds fluorescent powder, it can
To absorb light, while being discharged again.When wound lacks oxygen, the fluorescent powder in this bandage will redden, such as
Fruit oxygen is sufficient, then can show green light.The oxygen supply situation of wound can be thus judged by fluorescence color.More than but
The method flow of these monitoring wound surface body fluid physicochemical properties is complicated, somewhat expensive, and cannot be carried out to wound real-time
Monitoring can not carry out optimal processing on optimal opportunity to wound.
It can be seen that the prior art is primarily present following defect：
(1) poor accuracy, a large amount of subjectivities and experience for relying on people.
(2) according to Physico-chemical tests method, somewhat expensive, flow is complicated, poor in timeliness.
(3) it can not monitor in real time, to adjust wound physicochemical environment in real time, miss best conditioning opportunity.
