Definitions
- the present invention relates to a device for detecting, in a patient, the observance of an oxygen therapy treatment with a continuous supply of oxygen and the use of this device.
- the invention also relates to a method for monitoring adherence to an oxygen therapy treatment.
- COPD chronic obstructive pulmonary disease
- Oxygen therapy is an effective treatment for patients with respiratory insufficiency, especially COPD.
- the treatment if properly followed, can lead to a marked improvement in the quality of life of the patient and reduce the number of exacerbations of the disease and therefore of hospitalizations.
- US-A-5,706,801 discloses a device used to provide oxygen enriched air, concentrated or compressed, to a patient via a diffuser. It includes a detection and communication system to be used periodically to check the performance of the device and whether the oxygen supplied to the patient corresponds to what has been prescribed, that is to say if the flow rate and oxygen concentration are in accordance with the doctor's prescription. However, this device does not detect the presence of the patient and recover elements on his health.
- the document US-A-2007/0023039 teaches an apparatus which makes it possible to enrich the patient's environment with oxygen, to detect the patient's breathing but not his respiratory frequency, and to check whether he observes his treatment. It comprises, between the oxygen source and the cannula, an ultrasonic sensor which measures the speed of propagation of the sound waves and the flow rate of oxygen entering the cannula and, moreover, a component for synchronizing or regulating the demand for oxygen. oxygen at the moment of breathing. A frequency shift due to breathing is used to detect the patient's breathing (frequencies calculated from sound waves). However, at no time is the respiratory rate measured.
- a solution of the invention is then a device for the implementation of a system for the detection in a patient of the observance of an oxygen therapy treatment with an oxygen supply, allowing the recording of data of said processing and allowing the transmission of said data.
- the device of the invention comprises:
- two absolute pressure sensors one for measuring the pressure in the cannula for delivering oxygen to the patient's airways, particularly for the nasal passages, the other for measuring atmospheric pressure, or a differential pressure sensor ;
- a microprocessor implementing an algorithm capable of transforming the pressure measurements into respiratory frequencies of the patient and of deducing therefrom the duration of the daily treatment;
- the device can also adapt to a discontinuous supply, that is to say, only during the patient's inspirations.
- the device is located between the patient's nasal cannula and the oxygen source and is adaptable to the use of standard cannulas that are not specifically designed for use with said device. They are cannulas that meet the standard NF EN 13544-2 ("Respiratory Therapy Equipment -
- the device can be adapted to oxygen sources conventionally used in oxygen therapy, chosen from a compressed oxygen bottle, an oxygen concentrator and a liquid oxygen tank.
- oxygen sources conventionally used in oxygen therapy, chosen from a compressed oxygen bottle, an oxygen concentrator and a liquid oxygen tank.
- the flow rate of oxygen is between 0.5 and 4 1 / minute.
- this flow is adapted to the medical prescription.
- the device of the invention has a volume and weight sufficiently small for it to be portable by the patient without traction on the nasal cannula connecting the source of oxygen to the patient.
- the weight of the device is between 20 and 100 g, preferably between 25 and 80 g and even more preferably between about 30 and 50 g.
- the device can optionally be worn on the belt by means of a system of hooked adapted or the neck with a hanging pendant system.
- the device according to the invention can communicate the data recorded by radiofrequency to a desktop or laptop computer, a personal digital assistant (PDA) or another device capable of directly recording the transmitted data, or to a GSM modem that will send remotely , one or more messages, such as SMS or the like, containing the recordings of the device to a health center.
- PDA personal digital assistant
- GSM Global System for Mobile communications
- the device uses a radio frequency in free Industrial Scientific Medical (ISM) frequency bands for communication between 800 MHz and 5 GHz, preferably between 850 MHz and 3 GHz, even more preferably 868 MHz or 2.4 MHz. GHz.
- ISM free Industrial Scientific Medical
- the invention also relates to the use of a device according to the invention for monitoring the compliance of an oxygen therapy treatment by measuring the duration of treatment of the patient and its respiratory rate.
- the invention also relates to a method for monitoring the observance of an oxygen treatment by measuring the duration of treatment of the patient, characterized in that it comprises the following steps:
- the transformation of pressure values into respiratory rate using an algorithm.
- the objective of this method is to detect with at least two sensors, on the one hand, the average overpressure in the cannula due to oxygen flow, and on the other hand pressure variations related to inspirations (depression) and expiration (overpressure) of the patient in the cannula, the respiratory rate being deduced from the pressure variations related to the inspirations / expirations of the patient.
- the transformation of pressure values into respiratory rate is done using an algorithm called "FFT” or an algorithm called "TDS”.
- the algorithm is such that it can filter the interference caused by oxygen sources.
- the algorithms use the pressure values measured periodically over a determined period of time, that is to say they use a measurement window comprising a fixed number of samples.
- the principle of use of the FFT algorithm is as follows.
- the Fourier Transform analysis method is applied to the signals received in the measurement window. Some frequency signals are then filtered, such as the frequency signals typical of the oxygen sources and in particular oxygen concentrators as well as the lowest and highest frequency signals not corresponding to the respiratory frequency signals. Finally, the frequency resulting from the Fourier Transform analysis which will have the highest spectral power will be considered as the actual respiratory rate.
- this type of algorithm requires the recording of the frequency spectrum for each oxygen source. However, this step is not generally necessary if the frequencies below the minimum threshold and above the maximum threshold of the respiratory rate are not taken into account when calculating the respiratory rate. It is therefore recommended for greater simplicity (no information is required regarding the oxygen source) and the quality of the results does not take into account the spectral powers at these frequencies when using this type of oxygen. algorithm and in particular when using multiple oxygen sources.
- the principle of using the TDS algorithm for its part is to detect when the filtered pressure signal to eliminate the frequencies due to the oxygen sources intersects an upper threshold signal and a lower threshold signal.
- the lower and upper threshold signals are constructed from the mean and standard deviation of the last filtered pressure signal data.
- the algorithm records this event as "high”.
- the algorithm records this event as "low”. It records an event again as "high” when the signal comes from a lower threshold and crosses the upper threshold.
- the instantaneous breathing period is the counting of the samples between these two "high” events.
- the pressure data in the cannula are measured during successive first periods ti with a very low consumption of energy, these data measured during said first periods t i are exploited by said algorithm for second periods t 2 during which no other additional pressure data is recorded, these second periods t 2 requiring energy consumption for the calculation for transforming the pressure values into respiratory rate, and with t 2 which is a multiple of ti.
- the measurement period ti is between 20 seconds and 120 seconds and preferably around 60 seconds
- - Figure 1 is a schematic representation of the possible communication modes of the device
- - Figure 2 is a schematic representation of the device comprising a tip and more particularly of the internal cavity of said device;
- FIG. 3A is a schematic representation of the device comprising a system hooked to the belt;
- FIG. 3B is a schematic representation of the device comprising two end caps and a pendent hanging system
- FIG. 4 is a diagram of the steps included in the method for monitoring compliance with an oxygen therapy treatment.
- Figure 1 illustrates the possible communication modes of the device according to the invention.
- the device (1) can transmit the recorded data by radio frequency (RF) to a personal computer, PDA or other device capable of directly recording the transmitted data (2), or to a GSM modem (3), data recorded by (2) and by (3) being subsequently sent to the care center (4).
- Figure 2 illustrates the inner cavity of the device according to the invention (1) which comprises, inter alia, a battery (5) and a microprocessor (6). It is also possible to observe in this figure the presence of a single endpiece (7).
- RF radio frequency
- FIG. 3A illustrates the device according to the invention comprising a system hooked to the belt (8).
- FIG. 3B illustrates a second embodiment of said device comprising two endpieces (7) with a pendant hanging device (9). It is understood that the hanging systems can be found both on the device to a tip that two bits.
- Figure 4 illustrates the different steps for monitoring adherence to an oxygen therapy treatment.
- the pressure data in the cannula are measured during successive periods ti.
- the periods ti are interspersed with periods t 2 , during which the measured pressure data are exploited by an algorithm.
- the pressure in the cannula is measured successively throughout the duration of the treatment by sensors for a period ti of 60s called "measuring window".
- t 2 Between two measuring windows there is therefore a period of time t 2 during which the pressure is not recorded. It has been chosen that t 2 be a multiple of t i in order to leave a minimum period of time between two windows as well as a period of time for the exploitation of the data.
- the period between the beginning of a measurement window and the start of the next window is called the "window period” and has a duration equal to a multiple> 2 of the measurement window duration (60s).
- the pressure signal on 60s is acquired then one must determine if there is treatment on the measurement window and in this case calculate the corresponding respiratory rate.
- the results obtained are accumulated on each of the windows for a given number of periods between two measurement windows (> 1). All of these periods are called “period for rendering the results”.
- the calculation of the treatment time (sum of the duration of the periods between 2 windows for which treatment has been observed) is made as well as the calculation of the mean and maximum respiratory rate (mean and maximum respiratory frequencies calculated on each period between 2 measurements).
- the device of the invention appears to be truly innovative since it can be worn continuously by patients at home, thanks to its advanced integration - small size, low weight, high autonomy and adaptability to different sources of oxygen, and makes it possible to measure and communicate remotely the information relating to the observance of their oxygen treatment, in particular the effective treatment time whatever the source.
- this device allows monitoring and safety in home autonomy never reached through the possibility of alarming the patient and his care center in case of non-prescription, to avoid costly hospitalization.
