Bluetooth-based wireless telemonitor system

Abstract

The invention discloses a Bluetooth-based wireless telemonitor system, which comprises an acquisition terminal, a bedside unit and a central station. Data transmission between the acquisition terminal and the bedside unit is achieved through wireless Bluetooth, and the bedside unit transmits data to the central station. The acquisition terminal at least comprises two physiological acquisition modules. The bedside unit is provided with a storage module, a central control unit, a man-machine interface and a Bluetooth transmission module. Digitally converted signals from the physiological acquisition modules are transmitted to the central control unit of the acquisition terminal, and are organized prior to being transmitted to the Bluetooth module. The system employs the wireless Bluetooth technology, Bluetooth protocol is self-adaptive and capable of automatically frequency-hopping, and accordingly transmission reliability and communication rate can be guaranteed. The acquisition terminal is low in power consumption, and capable of continuously operating over more than 24 hours with single lithium ion batteries.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a bluetooth-based wireless telemetry monitoring method and system. Background technique [0002] Existing conventional bedside monitors are usually wired and movable with 220V mains power supply. When in use, the monitor is fixed beside the bed, and patients are basically unable to move during monitoring. For patients who need to monitor the bed activities, it has caused a lot of inconvenience. [0003] Existing portable wireless telemetry monitor has the following disadvantages: [0004] The parameters are incomplete, only 1 or 2 parameters such as ECG and blood oxygen, which cannot meet the needs of clinical monitoring; [0005] Using WIFI wireless technology, the system consumes a lot of power, resulting in a large product size and short continuous working time; [0006] Using GPRS wireless technology, the data volume of the wireless channel is small, and there is a...

Problems solved by technology

[0004] The parameters are incomplete, only 1 or 2 parameters such as ECG and blood oxygen, which cannot meet the needs of clinical monitoring;

[0005] Using WIFI wireless technology, the system consumes a lot of power, resulting in a large product size and short continuous working time;

[0006] Using GPRS wireless technology, the data volume of the wireless channel is small, and there is a large delay, and it is impossible to transmit signals with a large amount of data in real time;

[0007] At present, all telemetry monitoring has canceled the bedside machine, and the terminal is directly connected to the central monitoring system. This system is very different from the conventional bedside monitor, and it is difficult for users to accept and use it.
