Detailed introduction

心率 体温和活动量 等生理参数。 The implantable physiological signal wireless telemetry system is used for long-term measurement of physiological parameters such as heart rate , body temperature, and activity of various animals such as awake, unconstrained rats, mice, rabbits, beagles, monkeys, and fish . Using this system can ensure that the animals move freely in the cage without anesthesia or restraint, so the measured physiological signals can better reflect the physiological conditions of the animals in the natural state .Can be used for biological rhythm research and related vital signs monitoring .


无线遥测和记录实验动物 的: 心率、体温、 活动量 . The implantable physiological signal wireless telemetry system can wirelessly telemeter and record laboratory animals : heart rate, body temperature, and activity .  


式生理信号无线遥测系 由植入体 (E-Mitter) 、接收 数据转换器 (Receiver) 、电缆和记录分析计算机 ( VitalView ) 构成。 The implantable physiological signal wireless telemetry system consists of an implant (E-Mitter) , a receiver data converter (Receiver) , a cable, and a record analysis computer ( VitalView ) . 厘米大小的植入体 E-Mitter 集成了传感器、放大器和无线信号发射器,根据测量信号不同有多种规格。 The 1- cm implant E-Mitter integrates sensors, amplifiers, and wireless signal transmitters. There are various specifications depending on the measurement signal. E-Mitter 转发器不需电池 接收数据转换器 (Receiver) 输出电力。 The implanted E-Mitter transponder does not need a battery , and the receiver data converter (Receiver) outputs power. 将植入体埋入动物皮下,生理信号被植入体采集到并转换成相应的电信号后用无线电发射出来,由饲养笼下 方的接收器接收到并传递给数据转换器,完成数据转换后送入中央处理器进行数据处理。 The experimenter buried the implant under the skin of the animal. The physiological signal was collected by the implant and converted into the corresponding electrical signal. It was then transmitted by radio, received by the receiver below the breeding cage and passed to the data converter. After the data is converted, it is sent to the central processing unit for data processing. 32 个接收器,完成大规模的试验 The system can connect up to 32 receivers at the same time to complete large-scale experiments .


(E-Mitter) 是植入在动物体内的微型设备 , 它集成了传感器, 放大器 数字转换 无线发射的功能并解决了生物体的抗排异反应 Implant (E-Mitter) is a miniature device implanted in an animal . It integrates the functions of sensors, amplifiers , digital conversion , wireless transmission and solves the anti-rejection response of the organism . 入体有用于测量生物心率 体温和活动量等多种参数的规格 The implant has specifications for measuring various parameters such as biological heart rate , body temperature, and activity .

ER4000 signal receiver
ER4000 signal receiver is used to charge E-Mitters and receive measurement data returned by E-Mitters. Suitable for standard rat and mouse cages.

主要参数 The main parameters of the signal receiver

ER-4000Energizer / Receiver size 56 cm x 29 cm x 7 cm
Form of communication RS 232 serial
Maximum number of excitation receivers 32
Number of Excited Receivers Supported by a Single Power Supply 4
Exciting receiver requires space 30 cm (horizontal); 20 cm (vertical)
E-Mitter transmission range 12 cm above ER-4000

VitalView software

The excitation receiver and sensor are connected to the computer via VitalView software. A maximum of 240 data channels can be recorded, with 120 test objects typically used, and up to 32 test objects for E-mitter systems.


VitalView software can set experimental parameters and collect data. The software manages the connection to the hardware and stores basic graphical data analysis. 可以输出数据。 The software also provides data display in statistical form, which can output data.

 

Telemetry-used to monitor temperature, gross motor activity and heart rate data.
Physiological and behavioral monitoring of transgenic 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.
