無線遙測實(shí)驗(yàn)動(dòng)物的：活動(dòng)量、體溫、心率

VitalView植入式生理信號無線遙測系統(tǒng)用于長時(shí)間測量清醒無束縛的鼠兔貓狗猴魚等動(dòng)物的心率、體溫和活動(dòng)量等生理參數(shù)。使用此系統(tǒng)可以保證動(dòng)物在籠內(nèi)自由活動(dòng)，不需要麻醉或束縛，這樣測量到的生理信號更能反映自然狀態(tài)下的動(dòng)物生理狀況，滿足GLP 實(shí)驗(yàn)室要求.

VitalView植入式生理信號無線遙測系統(tǒng)由植入體(E-Mitter)、接收 數(shù)據(jù)轉(zhuǎn)換器(Receiver)、電纜和記錄分析計(jì)算機(jī)(VitalView )構(gòu)成。1-厘米大小的植入體E-Mitter集成了傳感器、放大器和無線信號發(fā)射器，根據(jù)測量信號不同有多種規(guī)格。植入式E-Mitter轉(zhuǎn)發(fā)器不需電池， 由接收數(shù)據(jù)轉(zhuǎn)換器(Receiver)輸出電力。操作者將植入體埋入動(dòng)物皮下，生理信號被植入體采集到并轉(zhuǎn)換成相應(yīng)的電信號后用無線電發(fā)射出來，由飼養(yǎng)籠下方的接收器接收到并傳遞給數(shù)據(jù)轉(zhuǎn)換器，完成數(shù)據(jù)轉(zhuǎn)換后送入中央處理器進(jìn)行數(shù)據(jù)處理。系統(tǒng)*多可同時(shí)連接32個(gè)接收器，完成大規(guī)模的試驗(yàn)。

植入體(E-Mitter)是植入在動(dòng)物體內(nèi)的微型設(shè)備，它集成了傳感器，放大器，數(shù)字轉(zhuǎn)換，無線發(fā)射的功能并解決了生物體的抗排異反應(yīng)。植入體有用于測量生物心率，體溫和活動(dòng)量等多種參數(shù)的規(guī)格。

VitalView植入式生理信號無線遙測系統(tǒng)的特點(diǎn)：

·無線遙測

·植入式E-Mitter轉(zhuǎn)發(fā)器沒有電池

·長期監(jiān)測-植入裝置后允許連續(xù)、遙測實(shí)驗(yàn)動(dòng)物一生

·準(zhǔn)確、可靠， 報(bào)告清醒無束縛動(dòng)物的生理和行為數(shù)據(jù)

Telemetry – used to monitor temperature， gross motor activity and heart rate data.

Physiological and behavioral monitoring oftransgenic mice and other laboratory animals has never been simpler. Through the use of biotelemetry and a variety of available sensors， it is possible for VitalView to monitor up to seven different physiological or behavioral parameters from a single laboratory subject

Combinations of the following parameters may be monitored for multiple laboratory subjects using VitalView:

Body Core Temperature

Heart Rate

Gross Motor Activity

Running Wheel Turns

Drinking/Licking Frequency

Feeding Behavior

Ambient Temperature

Ambient Light

E-Mitter Battery-Free Implantable Transponders

Using telemetry to provide temperature， gross motor activity and heart rate data. An E-Mitter is a small implantable transponder that is powered by capturing energy from electrical fields generated by the ER-4000 Energizer/Receiver. This allows the E-Mitter to operate without batteries and remain implanted indefinitely to monitor the subject''s temperature， activity or heart rate. As a result， high costs and downtime of explantation， refurbishment and reimplantation are avoided.
