Development Of The Wearable Respiration Parameter Monitor And Wireless Transmission System

Respiration is the exchanging process of gas between human's body and the environment. It is the important physiological process of human. The detection of the respiration is also a important constitute of the modern iatrical ward technology. The respiratory frequency is a significant parameter of the respiration. We can obtain many hidden information through analysis of it . For the detection for the respiratory frequency is easy to realize, it is the primary object for the existing respiratory detecting equipment.Design of a wearable system is that one kind of collection moves the medical sensor and wireless data communication measures the low physiology load new and developing checking up pattern. wearable sensor has broken tradition medical treatment instrument measurement way , style has measured method with being next to the skin melting to enter life monitoring life indication , the electrode has developed from the wet electrode , the dry electrode to "spinning and weaving electrode " , has had the fine man-machine interface , has been design idea new and original be once growing safe low physiology , mentality load detecting technology , implication among them. The wearable sensor , distributed data collect system , wireless short distance low rate data communication,virtual instrument platform , modularization multiple parameter check, the continuous displacement collecting information monitors these integrated feasible technology life bodies having realized miniaturization-- convenience carry --wearable propulsion.wearable technology as designing idea, applying respiratory inductive plethysmograph(RIP), designed wearable breath sensor. Respiratory inductive plethysmograph is one kind of high performance breath measurement technology, It's able to accurate depict the mark chest, the abdomen respiratory movement curve being able to determine the amounts of the components of a substance breathing volume course calibrating , gain quantify information such as tidal volume , breathable amounts of lung , be to there be no the effective means that the wound , the development breath pattern monitor. By being a technology's turn to be able to gain rich respiratory system physiology parameters, if respiratory rate , air-breathing time time parameter such as fractional , sucking / to call a ratio, tidal volume , every mark of breathable amounts , belly breath contribution are more parametric than waiting for volume , can gain breath Mechanics parameters such as breath flow rate , peak value air-breathing flow rate. Breath measurement technology has keen merit such as accurate , gaining quantify information , resisting to move the load disturbing an ability being put into use by force, going to the lavatory, to the patient low of signal relatively other , longtime dynamic measurement especially suitable is put into use.With the wireless communication developing constantly, facing to the low cost equipment, ZigBee technology appeared in recent years. It is a bidirectional wireless communication technology which is less distance, lower complex, lower power loss, lower data rate and lower cost. It has the widespread prospect in environment monitoring, military, medical industry, family intelligence monitoring and other commercial domains.The holistic idea in design of system: Judge by breath signal characteristic, applying respiratory inductive plethysmograph technology, constant excitations of amplitude electric current depicting mark importing frequency in the coil being 460 KHz in breath induced coil, the circle both ends voltage signal extracting outgoing line, again course preposition amplification , detection , wave filtering , host amplification circuit detecting take place breath signal wave form, the module CC1100 launch goes out after the data collect , the data handling queen, from wireless radio frequency, The far end carries out the data real time display by that CC1100 receives the machine communicating by letter by serial the day after tomorrow believing sending in PC. System includes six modules mainly: And central authority controller module structure builds , design , A/D stimulating source module design , signal to abstract the module design , signal treatment module change the module design and monolithic machine procedure write, the development coordinating super ordination machine demonstrates a software, the wireless breath coming true ZigBee based monitors.
