        產品詳情

        植入式生理信號無線遙測系統用于長時間測量清醒無束縛的大鼠、小鼠、兔子、比格犬、猴子、魚等多種動物的心率、體溫和活動量等生理參數。使用此系統可以保證動物在籠內自由活動,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下的動物生理狀況??捎糜谏锕澛裳芯亢拖嚓P的生命體征監測。


        植入式生理信號無線遙測系統可無線遙測和記錄實驗動物的:心率、體溫、活動量.  


        植入式生理信號無線遙測系統由植入體(E-Mitter)、接收數據轉換器(Receiver)、電纜和記錄分析計算機(VitalView)構成。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射器,根據測量信號不同有多種規格。植入式E-Mitter轉發器不需電池,由接收數據轉換器(Receiver)輸出電力。實驗人員將植入體埋入動物皮下,生理信號被植入體采集到并轉換成相應的電信號后用無線電發射出來,由飼養籠下方的接收器接收到并傳遞給數據轉換器,完成數據轉換后送入處理器進行數據處理。系統最多可同時連接32個接收器,完成大規模的試驗。


        植入體(E-Mitter)是植入在動物體內的微型設備,它集成了傳感器,放大器,數字轉換,無線發射的功能并解決了生物體的抗排異反應。植入體有用于測量生物心率,體溫和活動量等多種參數的規格。

        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.


        如只需要測量大鼠、小鼠的核心體溫,可以選擇植入式體溫膠囊,對體溫數據進行遙測:
