- Document FR-A-2,727,850 discloses a method which comprises the following successive steps: in an autonomous device carried by a patient: a) acquisition of raw data from at least one measurement channel by collection on a patient d 'an electrical signal and possible digitization of this signal, b) preprocessing of this raw data, so as to produce a set of analysis result data, c) recording of the results and the raw data possibly compressed, in a memory of 1 device, d) constitution of a results file obtained by the preprocessing of step b, and e) transmission to a remote site of this results file, and to the remote site f) reception of the results file transmitted by at least one autonomous device, g) processing of the result file thus received, so as to produce [diagnostic] data interpretable by an operator.
- the first object of the present invention is to improve the precision and finesse of detection carried out in surveillance.
- the invention also allows monitoring and reaction of nursing staff.
- an embodiment of the device according to the invention makes it possible to remotely control peripheral care devices, such as a self-propelled syringe in order to react immediately to the alarm, without any delay.
- this medicine can be injected under the sole responsibility of a nurse because apart from the antagonization of morphine and related substances there is no effect of its own and its use is without risk.
- the only imperative is the time factor.
- the brain is a fragile organ that only has three minutes of autonomy in case of anoxia. Beyond that, irreversible lesions appear.
- the immediate reaction made possible by the invention can have a beneficial character for the patient.
- the present invention allows the recording and the exploitation of a reference state of the patient recorded at the start of monitoring and allowing a comparison with his future evolution.
- the present invention relates to a method for monitoring the value of physiological parameters comprising a phase for measuring the value of one or more physiological parameters and a phase for transmitting the measured data from a module carried by the patient to a measurement unit.
- control characterized by the fact that the trend trend curve of the value of each physiological parameter is stored and analyzed to determine the slope of a regression line.
- An alarm is triggered when the calculated slope leaves a predetermined range of values.
- This process could present the embodiments introduced below: - a storage and analysis of the trend curves is carried out over a period of one hour or 24 hours.
- the memory of the module carried by the patient is periodically discharged to the control unit, in order to limit the memory capacity of the module carried.
