Description
[technical field]
The utility model relates to a kind of wireless launcher, particularly a kind of wireless monitoring terminal of remote controlled monitoring system.
[background technology]
From Waller in 1887 first since human body records electrocardio-activity, just learn as long as put two electrodes at any position of human body, with lead it is linked to each other with special galvanometer and to form a closed-loop path, can record the electrical activity of heart in cardiac cycle and change, the external circuit connection of this kind is referred to as to lead.This test electrode (+) that leads, contrast electrode (-) and the ground electrode position in the body placement is depended in the definition of leading.According to the position of placing electrode and with electrocardiograph mode of connection different multiple combination is arranged, constitute different leading---the system of leading.Einthoven foundation standard I, II, III led and the equilateral triangle theory in 1903, and making it becomes the standard lead that cardiogram detects, and uses till today.Nineteen forty-two Goldberger has revised the unipolar extremity lead negative input end, and with the centra electric terminals that R, L, F3 end are formed, changing the reference of forming at two ends into is RL, LF and FR; Eliminate the common mode inhibition of exploring electrode (F, R, L) signal self and amplified; The result makes the recording geometry wave amplitude increase 50%, so be called augmented limb lead (aVR, aVL, aVF).More than two kinds of lead systems obtain ECG information and emphasize particularly on different fields, be applicable to different occasions.The line that leads that is adopted is also different, is respectively three line and five lines that lead that lead.
Along with development of technology, occurred can remote diagnosis remote controlled monitoring system, system is by being carried at the telemetry transmitter of patient's monitoring terminal on one's body, launch after the information acquisition processing with patient, receiving magazine is finished Data Receiving, give central station and show printing etc., realize real-time monitoring, remote diagnosis etc.The great activity space of patient is given on the one hand in the application of radio-frequency technique in the remote measurement, but to central station the adjustment and the control of monitoring terminal function is brought restriction on the other hand.General bedside machine formula patient monitor can select to control monitoring and the ECG that the shows data of leading by menu, and the monitoring terminal in the remote controlled monitoring system is owing to be subjected to the restriction of factors such as volume, and function realizes fairly simple.Adopt three to lead under the line situation, only gather the II lead signals; Gather I, II, three signals that lead of V when adopting five to lead line.
Because the communication and the controlling mechanism of remote controlled monitoring system are unidirectional, promptly the remote measurement launch-box of monitoring terminal initiatively sends data, the passive reception of central station, and the centre does not have information feedback.Because the remote measurement launch-box of prior art does not possess the identification function of leading that inserts, and maybe can only insert leading of fixed type, central station must manually be provided with the type of leading, and could correctly receive, display message, causes very big inconvenience to use.
