Description

Title of the invention: System for remote monitoring of a patient at home

[0001] The invention relates to a system for remote monitoring or telesurveillance, i.e. a medical device for remote monitoring, of one (or more) patients treated at home by a medical treatment device, comprising computer means for processing data to remotely detect a treatment which is not or not sufficiently effective or a clinical condition which is deteriorating in the patient or any other non-compliant parameter, and alert means configured to inform and / or alert a user in the event of such detection, in particular a home health provider (HHP).

[0002] Patients suffering from chronic illness sometimes require the initiation of treatment by a medical device at home, i.e. outside a hospital or similar environment, and over long periods, typically several months or years.It could be a respiratory assistance device, such as a medical ventilator, a continuous positive airway pressure ventilator, an oxygen concentrator, an insulin pump, an apomorphine pump, an L-Dopa pump...or other.

[0003] Monitoring patients with chronic illnesses treated at home requires regular visits by professionals, such as technicians and / or nurses, to the patient's home, in particular to check the clinical efficacy and compliance with the treatment or the occurrence of any adverse effects, and to take operating records of the medical devices for the prescribing physician, for example. Such monitoring makes it possible to take actions to reinforce compliance and / or limit adverse effects, and to make adjustments or settings to the operating parameters of the treatment devices implemented.

[0004] Despite these regular follow-ups, many patients are treated in a manner that is not entirely effective due to poorly adapted settings or other reasons, such as weariness or discouragement of the patient leading to a drop in compliance with their treatment, or the occurrence of a technical problem.

[0005] Home visits to patients can be made more efficient by having prior knowledge of the patient's parameters, or even their history since the last visit. Variations in measured physiological parameters can also help to quickly and remotely detect the occurrence of acute events in certain patients, i.e. to make an early diagnosis, and potentially at a less severe stage, of the acute event.

[0006] It is therefore essential to be able to quickly detect an ineffective or insufficient treatment, or a deteriorating state of health in a patient treated at home with a medical treatment device, so as to be able to intervene quickly and avoid an impact on the state of health of the patient in question.

[0007] Remote monitoring or tele-tracking systems allow remote monitoring of one or more parameters from the medical device for treating the patient(s) treated at home, processing of the data or parameters monitored.

[0008] These systems trigger an alert to warn or inform a user, such as a PS AD, when one or more parameters are non-compliant, for example when their value exceeds a given threshold value.

[0009] Currently, the triggering of an alert is based solely on the value(s) of the data / parameters collected and processed electronically, i.e. without taking into account the action(s) already programmed, taken in response to an alert having been triggered, which are intended to correct the alert having been triggered.

[0010] We then witness an automatic generation of new occurrences of the alert, which no longer provide value to the remote monitoring, or even degrade its performance due to the number and / or frequency of alerts generated which may be high, and the time spent closing these new alerts without any more action than on the first occurrence of the alert.

[0011] Indeed, the intervention decided following a first alert does not always have an immediate effect on the measured parameters and therefore the triggering of successive alerts. For example, it may require a trip to the patient's home, a change in the setting of the medical treatment device on medical prescription, a therapeutic education action, etc.

[0012] The problem is therefore to avoid unnecessary repetitive alerts being generated in response to remote detection of one (or more) non-compliant parameters at the level of the medical device used to treat a patient at home and to the triggering of a first alert, i.e. to avoid one (or more) new occurrences of this alert being generated until a corrective intervention has been completely carried out.

[0013] The solution of the invention relates to a remote monitoring system, i.e. remote surveillance, of a patient treated at home by means of a medical device, said remote monitoring system comprising: - computer data processing means configured to cooperate with the medical device located at the patient's home, to collect at least one monitoring parameter provided by the medical device, said computer data processing means comprising:

[0014] . storage means for storing at least reference parameters compliant and

[0015] . at least one processor implementing at least one algorithm configured to process said at least one tracking parameter and trigger an alert when said at least one tracking parameter is non-compliant with at least one stored reference, that is, it reflects a non-conformity after comparison with at least one stored conforming reference parameter, and - a human-machine interface (HMI) comprising a display screen cooperating with the data processing computer means to display at least one alert on said display screen in response to an alert being triggered,

[0016] characterized in that the human-machine interface (HMI) comprises alert blocking means making it possible to prevent (i.e. block or prohibit), for a blocking duration, any repetition by the processor of the triggering of the alert having been triggered, i.e. any new occurrence of the alert already triggered and displayed on the HMI.

[0017] Depending on the embodiment considered, the system of the invention may comprise one or more of the following characteristics: - the HMI includes one or more selection keys or buttons, or the like, allowing the user to make one or more choices, adjustments, selections, validations or other actions. - the HMI includes a touchscreen display. - the HMI includes a touchscreen display configured to display one or more virtual selection keys. - the HMI includes a color or black and white display screen. - the given blocking duration is a predefined or adjustable duration. - the HMI is configured to allow the user to choose or select the blocking duration. - the blocking duration corresponds to the time required to complete an intervention initiated to resolve the current alert and / or to meet safety and / or regulatory requirements relating to the treatment of said patient. - typically, the blocking duration is several minutes, preferably one or several tens of minutes, or even one to several hours, or even in some cases from one to several days. - according to a first embodiment, the alert blocking means can be actuatable, activated or selected by the user. - the alert blocking means comprise a selection key, the actuation of which by the user causes any repetition of the triggering of the alert having been triggered to be blocked, for the blocking duration, in particular a virtual selection key displayed on the display screen of the HMI. - according to a second embodiment, the alert blocking means are at automated. In this case, the processor is programmed not to trigger a new alert during the pre-set and stored blocking period, once an alert has been triggered. the processor is configured to be able to repeat an alert that has already been triggered only when the blocking duration has elapsed. the alert blocking means are configured to deliver a blocking signal to the processor to prevent any reiteration of alert triggering during the blocking duration stored by the storage means. the processor is configured to compare said at least one tracking parameter with said at least one stored compliant reference parameter and deduce therefrom whether the tracking parameter is compliant or non-compliant with said stored reference parameter. said at least one stored compliant reference parameter is a reference threshold, i.e. a threshold value, in particular one or more high thresholds and / or low thresholds of one or more parameters. for example, the reference parameter may be a respiratory rate (RR) and a treatment duration or other. the display screen is configured to display one or more pieces of information relating to at least one triggered and / or blocked alert, in particular an alert and / or alert blocking date, a blocking duration and a blocking end date. said at least one processor implements at least one configured algorithm For :

[0018] . process said at least one tracking parameter and obtain at least one processed value of said at least one tracking parameter,

[0019] . compare said at least one processed value with at least one parameter of stored conforming reference, for example at least one stored threshold value or a range of values, and

[0020] . trigger an alert when said at least one value processed by said at least one tracking parameter becomes greater (eg a high threshold) or less than (eg a low threshold) said at least one stored compliant reference parameter. - it comprises electrical power supply means supplying the various elements of the system of the invention requiring electrical current to operate, in particular the processor and the display screen, for example a connection to the mains (110 / 220V). - the storage means include computer memory, such as flash memory or the like. the means of data transmission from the patient's medical device include a modem and / or a transmitting antenna or any other device enabling remote communication via the internet network or another network, such as GSM networks, in particular 4G / 5G, Lora or Sigfox, and / or via a virtual computing space of the "cloud" type. the data transmission means of the medical device are configured to remotely transmit at least said monitoring parameter. the data transmission means can either be integrated into the medical device or be part of an external module connected to the medical device, for example being attached to said medical device. the medical device is a medical ventilator, oxygen concentrator or other. the medical device is preferably a medical ventilator, i.e. a respiratory assistance device, comprising measuring means configured to determine at least one ventilatory parameter acting as a monitoring parameter. the alert triggered by the alert means in order to warn or inform the user, includes a prior notification, for example one or more characters (letters, numbers or others), in particular a message in text format, a color code, an icon, a bar graph, or other and / or their combinations, for example a bar graph of several colors. the monitoring parameter(s) from the medical device, typically a medical ventilator, comprise one or more primary monitoring parameters selected from respiratory rate (RR), leaks, an abnormal respiratory event (eg apneas, hypopneas, etc.) and / or treatment duration, preferably respiratory rate (RR) and treatment duration. the ventilatory parameter(s) from the medical device, typically a medical ventilator, include one or more secondary monitoring parameters selected from tidal volume (Vt), proportion (i.e. %) of spontaneous inspirations (relative to the total number of inspiratory cycles, i.e. triggered by the ventilator and the patient), and minute ventilation. the parameter(s) originating from the medical device, typically a medical ventilator, further comprise one or more operating parameters, in particular information relating to an absence of data transmission by the medical ventilator. This makes it possible to warn the user (e.g. PS AD) of a fault or malfunction of the ventilator affecting the proper transmission of data, i.e. parameters. - the monitoring parameter(s) are determined and / or measured over a given period that can be modified by a user, in particular a PSAD or healthcare staff, for example a period of several consecutive days. - the medical ventilator supplies air or an air / oxygen mixture at a pressure higher than atmospheric pressure (i.e. 1 bar absolute). - the computer data processing means include at least one remote computer server, i.e. located at a distance from the patient's home of at least several tens or hundreds of meters, typically several kilometers. - the processor is a microprocessor(s). - the processor(s) is(are) arranged on an electronic card(s). - the data storage means are configured to store at least one respiratory rate and / or duration of use alert threshold value. - the display screen can be that of a computer, a digital tablet or a multifunction telephone (i.e. smartphone).

[0021] In the context of the present invention: - the duration of use of non-invasive ventilation by a medical ventilator is the duration during which the patient used the ventilator during a given period of time, for example one day (i.e. 24 hours). - respiratory rate (RR) is the number of respiratory cycles, i.e. inspiration and expiration phases, per unit of time, measured in a patient, for example it is 12 to 20 cycles per minute (cycles / min) in a healthy adult but which can increase in the event of respiratory disorders or decrease during sleep. - leaks are gas (e.g. air) escaping around the mask, limiting the effectiveness of ventilation and causing discomfort for the patient. Leaks are estimated by the ventilator, for example, from measured gas flow rates. - the proportion (%) of spontaneous inspirations corresponds to the percentage of respiratory cycles which are initiated by the patient, and not by the ventilator, reported to the total number of cycles. - the number of respiratory events (i.e. apneas, hypopneas) per hour of treatment corresponds to the number of stops and / or reductions in airflow during a given period of time, for example greater than or equal to 10 seconds, also called the apnea-hypopnea index. - tidal volume (Vt) is the volume of air entering the patient's lungs during each respiratory cycle, for example an air volume of approximately 0.5 L. - the minute ventilation corresponds to the Vt.FR product.

[0022] A system according to the invention is suitable for use in monitoring a patient suffering from severe chronic respiratory failure, in particular chronic obstructive pulmonary disease (COPD), obesity-hypoventilation syndrome (OHS), or a neuromuscular disease, such as amyotrophic lateral sclerosis or Duchenne muscular dystrophy.

[0023] The invention will now be better understood thanks to the following detailed description, given for illustrative but non-limiting purposes, with reference to:

[0024] [Fig-1] which diagrams a patient monitoring system according to the invention.

[0025] [Fig.l] schematizes a monitoring system 10 of a patient P treated at home, for example a patient P under non-invasive ventilation (NIV) provided by a medical device 1, namely here a medical ventilator, typically a patient P treated for severe chronic respiratory failure, in particular chronic obstructive pulmonary disease (COPD), obesity-hypoventilation syndrome (OHS) or a neuromuscular disease, such as amyotrophic lateral sclerosis or Duchenne muscular dystrophy.

[0026] Here, as part of his treatment, the patient receives a pressurized respiratory assistance gas (i.e. > 1 bar abs), such as air or an air / O2 mixture, delivered by the medical ventilator, i.e. a respiratory assistance device, acting as the medical device 1. Conventionally, the gas is conveyed to the patient's airways by a flexible hose fluidically connected to the ventilator and equipped with a patient respiratory interface, such as a mask or the like (not shown). The medical ventilator is electrically powered by the electrical network (110 / 220V) or by one or more internal batteries, in particular rechargeable batteries, or the like.The medical ventilator comprises parameter measuring means configured to monitor one or more ventilatory parameters or monitoring parameters, such as for example the respiratory rate (expressed in cycles / min) and the duration of use (expressed in min for example) of the ventilator by the patient which reflects the duration during which the patient has inhaled respiratory gas, i.e. has followed his treatment.

[0027] According to the invention, a remote monitoring system 10 makes it possible to remotely monitor the medical treatment of the patient P treated at home.

[0028] The remote monitoring system 10 comprises computer data processing means 11, such as a remote computer server, cooperating with the medical device 1, i.e. the ventilator, located at the patient's home, to collect at least one monitoring parameter provided by the medical device 1.

[0029] Storage means 12 are also provided, such as a flash memory or the like, for storing compliant reference parameters, such as values- upper and / or lower thresholds or threshold value ranges.

[0030] One (or more) processors 13 implementing one (or more) algorithms makes it possible to process the monitoring parameter(s) provided by the medical device 1 and trigger 14 an audible and / or visual alert in the event of detection of one (or more) monitoring parameter(s) not conforming to one or more of the reference values ​​stored by the storage means 12, for example exceeding a high threshold value (i.e. maximum value) or falling outside a range of stored values.

[0031] A human-machine interface 20 comprising a display screen 21, preferably in color, cooperates with the data processing computer means 11 so as to display a visual alert 22 on the display screen 21 in response to an alert 14 being triggered by the processor 13.

[0032] According to the invention, alert blocking means 23 make it possible to prevent, for a pre-set or adjustable blocking duration, any repetition by the processor 13 of the triggering 14 of the alert having been triggered.

[0033] The elements of the system 10 requiring electric current to operate are electrically powered by the electrical network (110 / 220V), in particular the computer data processing means 11, typically the computer server and its components, the HMI, etc.

[0034] In order to ensure the transmissions 2 of monitoring parameters to the computer data processing means 11, i.e. to the server, there are provided at the level of the medical device 1, i.e. the ventilator, means of (remote)transmission of data configured to remotely transmit one or more monitoring parameters, such as ventilatory parameters provided by measuring means of the ventilator.

[0035] For example, the data (remote)transmission means 3 comprise a GSM or other type modem and a transmitting antenna. The transmitted tracking parameters 2 transit, for example via the internet network or another network, such as GSM, Lora or Sigfox networks, and / or can be processed in a virtual computing space of the “cloud” type.

[0036] The processing of the monitoring parameters is carried out within the computer data processing means 10 which comprise data reception means 15, configured to receive the monitoring parameters transmitted remotely 2 by the data transmission means 3 of the fan 1, which cooperate with the processor 13 implementing one or more processing algorithms.

[0037] Preferably, each day, the system 10 stores the latest data transmitted by the ventilator 1, in particular the duration of use and the respiratory rate (RR) and this, for several consecutive days, preferably between 5 and 10 days.

[0038] In the context of the present invention, the algorithm for processing the tracking parameters which is hosted on one (or more) computer servers 10, makes it possible to process remotely the measurements (i.e. measured monitoring parameters), for example here the respiratory rate (RR) and / or the duration of use carried out over several days, and transmitted remotely by the communicating ventilator 1 located at the patient's home.

[0039] The alert means displayed on the screen 21 of the HMI 20 make it possible to alert the user, such as a home health care provider (HHP), of any alert triggered by the processor 13 of the data processing computer means 10.

[0040] The alert notification comprises at least one visual alert 23, such as a notification, displayed on the screen 21, such as the computer monitor or display, the screen of a telephone or a digital tablet. The notification may comprise, for example, one or more characters (i.e., letters, numbers or other symbols), in particular a message in text format, but also a color code, an icon, a bar graph or any other graphic representation, and / or their combinations, for example a bar graph of several colors, for example green, yellow, storm and red depending on the severity of the alert.

[0041] Generally speaking, the system of the invention makes it possible to remotely detect an ineffective, insufficient or deteriorating NIV in a given patient, and to alert a user, such as an AD PS, to enable them to intervene quickly at the patient's home so as to avoid or minimize any negative impact on the state of health of said patient. The system of the invention therefore makes it possible to quickly, efficiently and remotely detect one or more elements / indicators representative of NIV type ventilation which is not or not sufficiently effective or which is deteriorating, and thus to put in place technical corrective actions or to inform health professionals about a drop in compliance or too significant a variation in the patient's respiratory rate, which may be a precursor sign of deterioration in the state of health of this patient.

[0042] Thanks to the alert blocking means 23, it is possible to prevent, for a blocking duration, any repetition by the processor 13 of an alert that has already been triggered, and this, preferably, for a predefined duration.

[0043] According to the invention, the processor 13 is configured to be able to repeat an alert that has already been triggered only when the blocking duration has elapsed.

[0044] The alert blocking means 23 may comprise one (or more) keys, buttons or the like, typically a key of the HMI 20, which, when activated, sends a blocking signal to the processor 13 which, in response to this blocking signal, prevents any reiteration of the triggering of the alert during the blocking duration prefixed and memorized by the storage means 12.

[0045] According to another embodiment, the alert blocking means 23 may comprise one (or more) keys, buttons or the like, such as a key of the HMI 20 which, when activated, makes it possible to select a given duration from among several different pre-set blocking durations and stored by the storage means 12, for example several blocking durations displayed by the screen 21 and selectable by means of the alert blocking means 23 within a drop-down menu or the like.

[0046] According to yet another embodiment, the blocking duration is adjustable or adjustable by the user via the HMI 20. He can set it by means of the alert blocking means 23, such as a key on the HMI 20. Typically, the blocking duration can be between one or more minutes to one or more hours, or even in certain cases, up to one or more days.

[0047] Generally speaking, the system of the invention is compatible with all communicating medical ventilators and is furthermore capable of censoring the parameters measured during periods of compliance that are too short so that the value is relevant.
