Uniquely designed experimental methods and matcheddevices are provided for meeting requirements of different experimental researches.
The provided devices have following characteristics:
-
Power consumption reaches μA level, enabling long-term continuous data collection, transmission, recording, analysis and processing of the system. Our technical team has been devoting to research on super-low power consumption circuit and program design. Electricity consumption is strictly controlled through various aspects including circuit design, component selection and software operation. In terms of design of different function modules, power consumption is allocated using μA level current. 550mAH battery used in current products can realize continuous 28-day recording of human ECG signals. Under the condition of identical volume, this working time is two times of that of foreign similar products.
-
Our products are highly integrated and compact, suitable for implantation into various experimental animals or convenient, non-invasive clinical measurement of physiological parameters. Products can be worn by people or implanted into small animals. Extremely small volume has no influence on normal physiological activities of animal or people. Light weight and miniaturization is originated from optimization of various aspects such as circuit element power supply. In the wireless telemetry system for small animal, volume of the signal collecting and emitting system implanted into mouse is <1.4ml, causing no additional burden to small animals. During the design of clinical medical product, it is more necessary to consider long-term wearing, numerous functions and other features. Therefore, the device must be designed as compact, miniature and light so that important physiological signal monitoring and examination can be accomplished under easy and comfortable conditions.
-
Multiple microprocessor control functions are combined and the microprocessor with the strongest function is selected, in order to complete signal collecting, sending, receiving and testing, and trigger corresponding function. For example, correspondingly adjust frequency, interval and intensity of nerve or heart stimulation signal according to the collected electrocardiosignal so as to achieve reasonable therapeutic effect of nerve regulation and heart stimulation. Intellectualized operating system will become the mainstream of new-generation scientific-research and clinical products.
-
Our products enhance efficiency, efficacy and animal welfare level of animal experiment works, and are suitable for long-term continuous observation in physiological, pharmacological, toxicological experiments and drug safety evaluation. In this way, it is possible to meet requirements of long-term chronic experiments, better conform to animal’s actual physiological conditions, avoid influences of acute reaction and anesthetics on experiment results, reduce animal killing rate, become more humanistic, increase efficiency of animal use, and significantly enhance animal welfare. Product packages are made of materials of good biocompatibility. Furthermore, water-resistance performance is especially reinforced. With regard to the control of animal’s inflammatory response and tissue proliferation, we also implement appropriate treatment (add slow-release coating of steroids) so that the implanted products can work in animal’s body continuously, normally and stably.
-
Focus is put on development of different functions including bioelectrical signals (ECG, EMG, EEG, nerve action potential and so on), pressure (blood pressure,intracranial pressure, chest pressure, respiratory system pressure, cardiac pressure, intraocular pressure, uterine pressure, gland pressure and so on), temperature, oxygen saturation, 3Daccelerated speed, skin electrical impedance, ultrasonic blood flow, ultrasonic measurement, non-contact electric signal collection, and dry electrode. Diverse combinations can meet requirements of different experiments and clinical applications. Additionally, many special electrodes and interfaces for use in corresponding measurement are also supplied.

Wireless transmission and remote monitoring
High-sensitivity receiving system can realize multi-band wireless bi-directional high-quality signal transmission and network-based remote monitoring. Wireless interactions and communications between different function modules are achieved. Alternatively, intelligent local area network is established for data exchange. Furthermore, there is combination with remote communication.

Intellectualized real-time continuous monitoring and managing of patient’s various physiological parameters can be done bothin hospitalor outof hospital. Patients or other testees can accept monitoring and examination under comfortable and unconstrained conditions. Wearable devices help testees return to normal living environment so that their daily life is not disturbed and limited. Moreover, for wearable devices, corresponding protective measures are designed. In special conditions, certain-degree function of first-aid treatment can be achieved. Contact us
