Description

METHOD AND DEVICE FOR MONITORING PHYSIOLOGICAL PARA ETERES

The present invention relates to a monitoring method and a device for ambulatory monitoring of the value of physiological parameters. The invention applies mainly to monitoring in the medical field and especially in the post-operative monitoring or risk patients.

The method and apparatus presented here allow an efficient monitoring and avoiding continual presence of personnel around the patient to monitor.

In this area, we connai t ambulatory monitoring devices do not give complete satisfaction.

In this context, French patent application FR 2750236 relates to an ambulatory monitor, continuous and remote physiological parameters measured by at least one sensor, carried by at least one person. It also relates to a method which uses such a device.

The device consists of a fixed station comprising a computer and a modem transceiver and at least one mobile electronic module worn by the person to be monitored, comprising means for analyzing physiological parameters transmitted by the or sensors, and a transceiver; the transmitter s- s receiver of the fixed station and the mobile electronic module operate in radio frequency. FR-A-2727850 discloses a method which comprises the following successive steps: in a standalone device worn by a patient: a) acquisition of raw data from at least one measuring channel by collection on a Patient an electric signal and possible digitizing this signal, b) pretreatment of the raw data to produce a set of results of data analysis, c) recording the results and optionally compressed raw data in a memory 1 unit, d) establishment of a results file obtained by the preprocessing step b and e) transmission to a remote site that results file, and remote site f) receipt of results file issued by at least a standalone device, g) processing the results file thus received, so as to generate data [diagnostic] interpretable by an operator. This process allows the formation of a results file but provides no operating evolutionary trend lines of the value of the measured physiological parameters. The devices according to the prior art are advantageous but can be improved. This is one of the purposes of the present invention to make improvements to this device.

Firstly, the devices according to the mentioned prior art allow only a limited detection of the patient's potential problems. Indeed, only a breach of threshold detection is performed. However, a sudden change in the value of one of the physiological parameters of the individual monitored may indicate a health problem even if this variation remains within the range chosen threshold.

Therefore, the change in the patient's state of health is not always perfectly detected by current devices. The first object of the present invention is to improve the accuracy and fineness detection performed in the monitoring.

The invention also enables monitoring and reaction caregivers. To this end, an embodiment of the device according to the invention can control, remote care of peripheral devices, such as a syringe autopulsée to respond immediately to the alarm, without any delay.

Moreover, the trip command of care devices can be operated automatically trigger the alarm device.

This variant of the invention will be particularly advantageous in the context of the fight against pain.

analgesia techniques controlled by the patient are being extended. In this case the patient manages his own morphine injections with a syringe autopulsée. But this technique requires mandatorily monitoring capillary oxygen saturation and heart rate as the main complication is the responsible overdose of insufficient up to respiratory arrest and cardiac arrest. The present invention brings a solution. The specific treatment of this respiratory distress is the injection of naloxone which is an antagonist of morphine. This drug antagonizes immediately respiratory depression and thus prevents severe complications. Unlike most other prescriptions the drug can be injected under the sole responsibility of a nurse because apart from the antagonism of morphine and related substances it n 'no independent effect and its use is safe. The only requirement is the time factor. The brain is a delicate organ that has only three minutes remaining when anoxia. In addition, irreversible damage occurs.

Therefore, the immediate reaction made possible by the invention may have a beneficial character to the patient.

Moreover, the method and device presented here provide a comprehensive analysis of the situation and the evolution of the health status of the individual. therefore carried out more than a picture of the health status at a given time.

Furthermore, the present invention allows the registration and operation of a patient's baseline recorded at the beginning of supervision and to allow comparison with future developments. Other objects and advantages will appear during the following description which is however given only.

The present invention relates to a method for monitoring the value of physiological parameters comprising a phase measurement of the value of one or more physiological parameters and a phase of transmission of the measured data from a module carried by the patient to a unit control characterized in that that stores and analyzes the development trend curve of the value of each physiological parameter to determine the slope of a regression line. an alarm is triggered when the calculated slope out of a predetermined range of values.

This method may present the embodiments introduced below: - performing a storage and analysis of the trend curves over a period of one hour or 24 hours.

- Module memory periodically discharge worn by the patient to the control unit, to limit the memory capacity of the common module. - is stored at the start of monitoring, the value of physiological parameters or for forming reference curves.

The invention also relates to a device adapted to implement the method comprising - at least one sensor for measuring the value of monitored physiological parameters, a control unit with display means, a module carried by the person to be monitored , transmission means between the common module and the control unit, at least one member alarm characterized in that it comprises: memory means for recording an evolution trendline the value of each physiological parameter, analytical means, from the trend line to determine the slope of a regression line and triggering the alarm when the calculated slope out of a predetermined range of values .

The accompanying drawings are given by way of example and not limiting. They represent an embodiment. They permit easy understanding of the invention.

FIG 1 is a general block diagram of the device according to the invention in a particular embodiment.

Ambulatory device 1 shown here comprises various components. Firstly, it comprises at least one measuring sensor shown schematically by element 5 in Figure 1. The one or more measuring sensors 5 may be of various types according to the nature of the physiological parameter being monitored. by physiological parameter is any type of data for defining the health status of the individual on a particular medical plan. For example, we can measure heart rate or temperature.

In the case of regular measurement of heart rate, of particular detect possible arrhythmias. Another constituent element of the device 1 is a unit 3 carried by the person to be monitored.

This module 3, small footprint, is fit to be worn regularly by the person. This allows a practical and fully mobile device 1.

Module 3 is on one hand connected to the sensor 5 as shown diagrammatically in Figure 1.

The module 3 comprise a memory area capable of storing data received from the sensors 5. Moreover, as shown, a screen 11 may be used for example to visualize the measurements or to display other information.

The device 1 according to the invention comprises a control unit 2. For example, a computer terminal may constitute the control unit. Computer functions are then operate for the purposes of the present invention.

As illustrated, transmission means are formed between the module 3 and the control unit 2. In this way, a regular transfer of information from the module to the control unit 2 is performed. It may form the transmission means in the form of current design transceivers referenced 8a, 8b in FIG 1.

However, other transmission routes are possible such as a modem transmission or satellite.

The control unit 2 also comprises storing means.

These means ensure the reception and storage of data from the sensors 5 via the module 3. The storage means may be formed by a ROM as a memory of the EEPROM type.

In a particular embodiment, the memory module is periodically discharge 3 to the storage means of the control unit 2. In this way one avoids overloading the memory of the module 3 which makes it possible to limit the capacity. The device according to the invention also comprises means of analysis. Indeed, the control unit 2 not only performs a reception and storage of the measured values. It also carries an operating values. To do this, the analysis means performs a linear regression calculation from the measured values ​​so as to determine the slope of the regression line. Then a comparison between the determined inclination value and the maximum or minimum values ​​prerecorded slope can be performed.

Furthermore, with respect to the state of the art technology, full storage of the values ​​measured by the sensors 5 is made. This creates continuous and regular trend lines of the evolution of physiological parameters. These trend lines are not only exploited by the analysis means also available at any time by the practitioner.

The control unit 2 presented here may also include an alarm member such as a ring or a visual message that can indicate the crossing of the slope value beyond the prerecorded values.

The control unit 2 may also comprise display means 9 as shown in Figure 1. For example, a computer screen can enable to form said display means 9.

To enable the practitioner to follow at all times monitoring patients, the device 1 may include a portable receiver 4 equipping the practitioner. The connection between the control unit 2 and the mobile receiver 4 may be effected through a transceiver 6 connected to the control unit 2 and a receiver 7 integral with the portable receiver 4. If necessary , a transmitter is also present to ensure a bidirectional link. The receiver 4 can itself also comprise a display 10 to display any messages necessary to the practitioner.

Depending on conditions, the nature of the physiological parameters to be monitored may change. To adapt the device to these possibilities, it may include a smart card reader allowing the use of processing cards. Each processing card will correspond to a set of parameters able to adapt the device functions as required of the practitioner. For example, treatment of the maps integrating acceptable maximum or minimum values ​​for physiological parameters or slope variations.

For the sake of centralization, the device 1 presented here can be connected to a computer network to globalize monitoring, for example at a hospital.

The device 1 described here allows the implementation of the method according to the invention.

This method allows the storage of evolution trend curves of the value of each physiological parameter and analysis.

In one embodiment of the method, the storage and analysis of trend lines is done on the basis of time periods, for example of 1 hour or 24 hours. Moreover, to have a baseline or comparison of changes in physiological parameters, we can make reference curves at the start of monitoring. Future trend curves can be analyzed in view of the reference curves. Preferably, use of the transmission means in the form of radio frequency transceivers as known from the prior art. The information supplied is thus very effective and practical. To respond quickly to a fault detected in the patient, the device may include care devices controlled via a serial transmission device.

A syringe device autopulsée can, for example, be the care devices.

Two examples of care devices through the transmission device, are presented below.

The command may initially come from the practitioner. In this context, the receiver 4 which it is provided comprises a transmitter portion in the direction of the transmission device directly or indirectly via the control unit 2.

It can also automatically control a health device when an alarm is triggered. Device operating parameters will then fixed in advance by the practitioner.
