E-Mitter（植入體系統(tǒng)）主要技術(shù)參數(shù):

ER4000 信號接收器
ER4000信號接收器用于給E-Mitters充電和接收E-Mitters傳回來的測量數(shù)據(jù)。適合標(biāo)準(zhǔn)的大小鼠飼養(yǎng)籠具。

信號接收器的主要參數(shù)

激發(fā)接收器和感應(yīng)器通過VitalView軟件連接到電腦。最多可以記錄240個數(shù)據(jù)通道典型應(yīng)用120個測試對象對于E-mitter系統(tǒng)最多32個測試對象。

VitalView軟件可以設(shè)置實驗參數(shù)和采集數(shù)據(jù)。軟件管理與硬件的連接并且儲存顯示基本的圖形化的數(shù)據(jù)分析。軟件也提供統(tǒng)計形式的數(shù)據(jù)顯示可以輸出數(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 telemetry 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(shù)據(jù)進(jìn)行遙測
