Wireless lead device of wireless sensor network architecture

Abstract

The invention relates to a wireless lead device of a wireless sensor network architecture. The wireless lead device of the wireless sensor network architecture comprises a lead and probe front end and a lead instrument end, the lead and probe front end is wirelessly connected with the lead instrument end to realize point-to-point communication and networking communication, so that a common monitor can be conveniently accessed to a monitoring network and the Internet, and the functions of movable monitoring, on-site monitoring, upper computer monitoring and the like are realized; the system has the characteristics of ad hoc network, multiple network nodes, low complexity, low power consumption and no maintenance.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a wireless lead device of a wireless sensor network architecture. Background technique [0002] Wireless lead electrocardiographs and wireless lead monitoring devices have been produced in the market, but they adopt the Bluetooth communication mode between a single lead and the ECG host or monitoring device, the communication signals of each lead are not only easy to interfere with each other, but also due to Too many leads lead to a waste of frequency resources; Bluetooth can connect up to 8 devices at the same time, and the types of devices are different, but the same device can only be connected to one, and the range is usually 10 meters; the small size of the chest lead is not considered And the installation location is special, requiring the antenna to be small in size and not have corners and other problems; the front end of the lead is equipped with pre-amplifica...

[0002] Wireless lead electrocardiographs and wireless lead monitoring devices have been produced in the market, but they adopt the Bluetooth communication mode between a single lead and the ECG host or monitoring device, the communication signals of each lead are not only easy to interfere with each other, but also due to Too many leads lead to a waste of frequency resources; Bluetooth can connect up to 8 devices at the same time, and the types of devices are different, but the same device can only be connected to one, and the range is usually 10 meters; the small size of the chest lead is not considered And the installation location is special, requiring the antenna to be small in size and not have corners and other problems; the front end of the lead is equipped with pre-amplification, filtering and other processing circuits composed of discrete components, the consistency is not good, and different instruments cannot be used interchangeably; The circuit modification of the original electrocardiogram machine or monitoring device has caused limitations in use; at the same time, the above-mentioned communication methods have to take into account factors such as the relative position and distance between each lead and the electrocardiogram machine or monitoring device, resulting in inconvenient use; because Bluetooth communication requires Pairing, the data collected by the lead can only be transmitted to a specific ECG machine or monitoring device, it is not interchangeable, and the data cannot be transmitted to other similar devices or host computers; there are also wireless lead signal lines that use right and wrong 2.4 GHZ (ISM) is a radio frequency communication technology solution that does not apply for frequency bands. It is difficult to network, has low reliability, and consumes a lot of power. There are also problems of mutual interference and collision between lead transmission signals.
