Description

Title of the invention: Portable physiological measuring device Technical field

[0001] The present invention relates to portable physiological measurement devices (hereinafter the measurement device), of the personal hand-held monitor (PHHM) type and incorporating a plurality of physiological data sensors. Such devices can be used in particular in the context of remote monitoring, for example by a doctor during a teleconsultation or during an asynchronous consultation. In English terminology, we generally speak of "telehealth" or "remote patient monitoring" (RPM). In the context of the description, the term RPM will be used.

[0002] One of the particularities of these devices is that they are operable in self-measurement, that is to say that the person holding the device is the person who is undergoing the measurements.

[0003] The measurements taken are physiological measurements of a user holding the measuring device in their hand. These measurements are representative of the user's state of health. Prior art

[0004] Many measuring devices exist. Some are capable of performing a single measurement: thermometer, stethoscope, ECG, etc., while others are capable of performing several of these measurements.

[0005] Among the electronic stethoscopes, we can cite those described in the following documents: US926547, US20220354451, US11741931, US20220031256, US20010030077, US20230142937, US5737429A, US5638453A. However, not all of these documents provide devices suitable for self-measurement and some are even explicitly designed to be held by a doctor. In addition, the number of measurements may be insufficient to have a device suitable for RPM.

[0006] Among the thermometers, we can cite that described in document WO2017114923A2 (in the name of Withings™).

[0007] Document US2022035445 in the name of EKO HEALTH™ and more generally all publications of this company describe an electronic stethoscope incorporating an electrocardiogram.

[0008] Other documents describe devices capable of making two or three measurements.

[0009] For example, document PL423977A1 ​​describes a stethoscope with an infrared sensor, but without detailing the integration.

[0010] For example, document WO2022200743 describes a device with a parallelepiped housing which integrates a stethoscope, an oximeter, an otoscope and a thermometer, in addition to a bra for pressure measurement.

[0011] For example, document US20200015774 describes a device with a circular handle for bringing a base into contact with a user. The base includes an electronic stethoscope which may also include a thermometer or an oximeter. The disclosure also mentions, without any details, the capture of ECG and ultrasound signals.

[0012] For example, document WO201704463 describes a finger-worn device for oximetry that integrates a stethoscope and an otoscope.

[0013] For example, document WO2022253723 describes an essentially cylindrical device with two opposite faces which comprise three physiological sensors: thermometer, stethoscope and oximeter.

[0014] For example, the Linktop 6-in-l™ product provides a square mini-slab-shaped device, having a temperature sensor and an electrode on a single side face, an optical sensor and an electrode on the square top face, and an electrode on the square bottom face.

[0015] However, these documents have limitations. One limitation lies in the transition between a conceptual idea and a functional product on the market. Another limitation lies in the number of measurements that can be carried out by each device, one or two measurements, sometimes three measurements. To have an effective RPM device, it is essential to maximize the number of measurements on a single device. Another limitation lies in ergonomics and practicality of use, even more so when the number of available measurements increases. Indeed, the measuring device must remain small and easy to handle by users who may be elderly and in poor health. These technical constraints have direct consequences on user adoption and retention. Summary

[0016] The description relates to measuring devices offering improved practicality of use. This practicality may relate to ergonomics. This practicality may relate to the number of measurements permitted by the device.

[0017] According to one aspect of the present description, there is presented a portable physiological measurement device which can be grasped by a manipulator comprising: - a housing of elongated shape in a direction of extension and comprising, in the direction of extension, a first end defining a first edge and a second end defining a second edge, - a first physiological extremity sensor positioned at the first extremity and comprising a functional surface intended to be positioned facing a user, the functional surface being inscribed in the edge at the level of the end, - a second physiological end sensor positioned at the level of the second end, - a physiological finger sensor arranged on the housing near the first end or the second end.

[0018] This device is easily manipulated by a user who is himself the manipulator. Thanks to the inscribed character of the first end sensor, the latter does not hinder gripping, whether with one hand or two hands.

[0019] More specifically, the device is configured so that when the device is gripped by a hand on the side of the first end, in the extension of the longitudinal direction, the physiological sensor does not interfere and in which the physiological finger sensor is positioned so that when gripped a finger of the hand can be in contact with the finger sensor.

[0020] In particular, the physiological finger sensor is arranged on the housing to receive an index finger of a hand and / or a thumb of a hand.

[0021] In one embodiment, the second end defines a second edge and the second physiological sensor comprises a functional surface inscribed in the second edge. This provides a symmetrical operating device for the end sensors, which does not interfere with one-handed (in either direction) and two-handed gripping.

[0022] In one embodiment, the device comprises a substantially parallelepiped shape with a front face and a rear face disposed between the first end and the second end. The second physiological end sensor is arranged on the rear face, proximate the second end.

[0023] In one embodiment, the distance along the direction of extension between the first end and the second end is a length L and "arranged near the first end (or the second end)" means "between the first edge (or the second edge) and strictly half the length L from the first edge (or the second edge), or even strictly a quarter of the length L from the first (or the second edge).

[0024] In one embodiment, the physiological extremity sensor, and in particular the functional surface of the physiological extremity sensor, is positioned within the volume defined by the housing or, in a variant, at most 1 mm outside the volume defined by the housing. This ensures that the extremity sensor does not interfere with gripping the device.

[0025] The physiological extremity sensor may be an audio sensor (e.g., piezoelectric) and the functional surface may comprise a membrane. The physiological extremity sensor may be a temperature sensor and the functional surface may include a cone. The end physiological sensor may be a spirometer and the functional surface may include a mouthpiece.

[0026] In one embodiment, the functional surface is orthogonal to the direction of extension at the end and / or the lateral face defined by the first edge (and / or the second edge) is orthogonal to the direction of extension at the end.

[0027] In one embodiment, the physiological finger sensor comprises an optical sensor, for example a PPG type sensor with LEDs or a laser. The optical sensor makes it possible in particular to measure a heart rate and its variations, or oxygen saturation.

[0028] In one embodiment, the physiological finger sensor is a first physiological finger sensor, arranged on the housing proximate the first end and the device further comprises a second physiological finger sensor, arranged on the housing proximate the second end.

[0029] For example, the first and / or second physiological finger sensor comprises an electrode. For example, the electrodes are electrocardiogram (ECG) electrodes. More particularly, there may be only two ECG electrodes to perform an ECG. This arrangement simplifies handling to have an ECG since it is sufficient to touch only two electrodes, and not three or more. Alternatively or additionally, the electrodes may be impedancemetry electrodes, for impedance analysis.

[0030] In one embodiment, the first physiological finger sensor and the second physiological finger sensor are aligned parallel to the extension direction.

[0031] In one embodiment, the device comprises a physical interface, for example a navigation button. The physical interface is then arranged on the housing and the second physiological finger sensor can be positioned on the physical interface.

[0032] In one embodiment, the device comprises an essentially parallelepiped shape with a front face and an upper face arranged between the first end and the second end, the front face and the upper face being connected, for example perpendicular to each other.

[0033] In one embodiment, the first physiological finger sensor and / or the second physiological finger sensor are positioned on the upper face.

[0034] In one embodiment, the device comprises a display.

[0035] The display may be located on the front face.

[0036] The device may comprise a gyrometer and / or an accelerometer configured to determine the spatial orientation of the device and to adapt the reading direction. of the display according to this orientation

[0037] In one embodiment, the device comprises a physical interface, for example a navigation button, positioned on the front face. The physical interface is positioned between the second edge and half, or even one-third, of a length of the housing along the direction of extension from the second edge. Alternatively, the physical interface is positioned between the first edge and half, or even one-third, of a length of the housing along the direction of extension from the first edge.

[0038] In one embodiment, the finger sensor is positioned within the volume defined by the housing or at most 2 mm outside the volume defined by the housing.

[0039] According to another aspect of the present disclosure, there is provided a method of using a device as described above. The method may comprise the following steps: - measurement with the physiological extremity sensor by the user in a one-handed handling position, - measurement with the physiological finger sensor by the user in a two-handed manipulation position.

[0040] The method may further comprise a measurement with the second physiological sensor by the user in a one-handed manipulation position,

[0041] In one embodiment, wherein the device comprises a display and a physical interface, the method further comprising a step of user selection of the measurement to be performed on the display with the physical interface in a navigation position. The navigation position is typically one-handed. Brief description of the drawings

[0055] General presentation

[0056] The present description will describe several embodiments and variants of physiological measurement devices which are portable, grippable by one or two hands and suitable for self-measurement. We will refer to the term "device" to simplify the language. By definition, the manipulator is the one who holds the device and the user is the one who undergoes the measurement. In the context of this description, unless otherwise stated, manipulator and user are the same.

[0057] The device integrates one or more physiological sensors to measure physiological characteristics (“physiological measurement”) of a user who is also the operator. In this regard, the sensor may be one of: a temperature sensor to measure the user’s body temperature, a sound sensor to measure heart or lung sounds, an ECG (electrocardiogram) sensor to measure heartbeat and rhythm, an impedance sensor, an optical sensor, such as a PPG (for “PhotoPlethysmoGraphy”) sensor for example, for oximetry, to measure blood oxygen saturation (SpO2) or other quantities such as heart rate, a force sensor, in particular to measure force or pressure relative to the finger (ultimately to determine blood pressure), a spirometer, etc.

[0058] By physiological measurement, it is meant measurements of physiological characteristics of a user (we will speak of user hereinafter), which reflect a state of health, such as: temperature, heart sounds, lung sounds, heart rate, arrhythmia, etc. In particular, in one embodiment, the device integrates at least two physiological sensors; in another embodiment, the device integrates at least three physiological sensors (for example: thermometer, stethoscope, ECG); in another embodiment, the device integrates at least four physiological sensors (for example: thermometer, stethoscope, ECG, PPG).

[0059] By portable, it is meant a device which is light and compact. The device can therefore be easily grasped by a user in one hand and the device can for example be easily stored in a drawer, a handbag or a trouser pocket. For example, the device weighs less than 250g, or even 150g. For example, the device has a volume of less than 20x5x10 cm, or even 18x3x5cm, or even 15x2.5x4cm.

[0060] The device has an elongated shape in a direction of extension, for example an essentially parallelepiped shape.

[0061] In addition, the device can be connected, in the sense that it can send data to a third-party device, such as a smartphone or a server. This connectivity allows the device to function as an RPM device, the user then becoming a patient of a remote doctor. The teleconsultation can be done synchronously, with live or quasi-live interaction with the doctor, or asynchronously. In synchronous mode, the patient uses the device to acquire physiological data which is immediately or almost immediately transmitted to the doctor (a few seconds later). In asynchronous mode, the patient uses the device when he can and the doctor consults the physiological data when he can, i.e. later in time.

[0062] The shape of the housing and the arrangement of the sensor(s) in the device is intended so that the latter can be easily used with one hand to perform certain physiological measurements (for example: temperature and sound of the heart or lungs) and with two hands to perform other physiological measurements (for example ECG or PPG). In one embodiment, the one-handed position may be similar to a remote control position, with which users are generally familiar, and the two-handed position may be similar to a video game console controller position, with which users are generally familiar as well.

[0063] The device is intended to be used for self-measurement. It must therefore be easily usable by a user so that they can take measurements on themselves.

[0064] However, the device must also be able to be used by two people, for example when one person is unable to operate the device (disabled or child for example). Thus, the constraints linked to the condition of use alone must not generate constraints of use by several people.

[0065] [Fig. 1] represents two three-dimensional views of a device 100 according to one embodiment. [Fig. 2] illustrates the device 100 according to four projections. [Fig. 3] represents a view of the device 100 during manipulation in a navigation position, with one hand. Figures 4 and 5 each illustrate a view of the device 100 during manipulation in a measurement position with one hand (for two different measurements). [Fig. 6] illustrates a view of the device 100 during manipulation in a measurement position with two hands.

[0066] The case

[0067] The device 100 comprises a housing 102 of elongated shape which defines an extension direction X. The housing 102 also defines two orthogonal transverse directions Y and Z. Subsequently, the notions of “transverse” are defined with respect to the direction X. This extension direction X is said to be principal because the device 100 has its largest dimension in this direction. The extension direction X is rectilinear in the figures but a curvature is possible to the extent that the handling of the device would not be significantly altered.

[0068] Along the direction of extension X, the housing 102 comprises a first end 102L (L for “Left” or gauche in French) and a second end 102R (R for “Right” or droit in French), opposite the first end 102L. The first end 102L defines a first edge 104L and the second end 102R defines a second edge 104R. Each edge 104L, 104R defines a closed curve (ovoid in shape in the figures due to the section of the housing 102 at the first end 102L and the second end 102R).

[0069] To allow easy gripping, each edge 104L, 104R has a length of less than 30cm, or even 15cm. The description will present in detail the different possible handling positions of the device 100 by a user.

[0070] In one embodiment, the distance L between the two edges 104L, 104R, along the extension direction X is less than 20cm, or even 15cm. This distance L makes it possible to guarantee the portable nature of the device 100.

[0071] In one embodiment, the distance L between the two edges 104L, 104R, along the direction of extension X is greater than 8cm, or even 10cm. This distance L makes it possible to guarantee that the device can be grasped by one hand and two hands. Indeed, a device that is too small cannot be easily handled, in particular by the whole person. world.

[0072] The device 100 is designed to be grasped by at least one of the two ends 102L, 104R with the hand in the extension of the housing 102 in the longitudinal direction. In particular, a navigation position is defined, illustrated in [Fig.3].

[0073] The housing 102 may have an essentially cylindrical shape, with a transverse section in the YZ plane (i.e. orthogonal to the direction of extension X) of convex shape. In one embodiment, this section has two axes of symmetry, for example the Y and Z axes as shown in the figures. The section is for example an oblong section, as illustrated in the figures, or a rectangular section (with more or less rounded angles), or a circular section.

[0074] By essentially cylindrical, it is meant that the section orthogonal to the direction of extension X does not exhibit any significant variation in dimension (for example less than 20% variation in maximum diameter).

[0075] The housing 102 is typically made of plastic material, to be lightweight, economical and electrically insulating. When the user holds the device 100, his or her hand(s) are mainly in contact with the housing 102. The housing 102 may be formed of several parts assembled together. In Figures 1 and 2, the housing 102 comprises two shells, denoted respectively 102a, 102b, which may be assembled at a junction parallel to the direction of extension X. Alternatively, the housing 102 is formed of a single shell. Other types of assembly are possible.

[0076] At least two faces connecting the edge 102L to the edge 102R can be defined for the housing 102. In the case of an oblong or rectangular section, a front face 102F (F for "Front" or avant in French), a rear face 102R (R for "Rear" or arrière in French) (opposite the front face), an upper face 102T (T for "Top" or haut in French), and a lower face 102U (U for "Under" or bas in French), opposite the upper face; finally the two edges 104L, 104R each define a lateral face. The front 102F and rear 102R faces are connected by the upper face 102T and the lower face 102U. In particular, the front face 102F and the upper face 102T are perpendicular or essentially perpendicular to each other (neglecting possible rounded shapes such as those visible in [Fig. 1]).

[0077] These face names are defined relative to the two-handed manipulation position illustrated in [Fig.6].

[0078] As illustrated in [Fig.2], each of the upper 102T and lower 102U faces extends mainly in a longitudinal plane XY. Each of the front 102F and rear 102R faces extends mainly in a longitudinal plane XZ, orthogonal to the XY plane. Each of the two edges 104L, 104R extends mainly in a transverse plane XZ, i.e. the side faces are also, in the figures, or thogonal to the direction of extension X. Rounded shapes for the front 102F, rear 102R, upper 102T and lower 102U faces can be provided, as illustrated in the figures, to avoid having an edge or thus facilitate gripping.

[0079] The front 102F and rear 102R faces have a height (the Z dimension) greater than the depth (the Y dimension) of the rear 102R and upper 102T faces. In other words, the housing 102 is higher than it is deep.

[0080] The front 102F and rear 102R faces have a length (the X dimension) greater than the height (the Z dimension). In other words, the housing 102 is longer than it is tall.

[0081] These size considerations apply similarly to the device 100. The device 100 has a length (X dimension) that is greater than a height (Z dimension) that is itself greater than a depth (Y dimension). For example, the length is at least 3 times greater than the height and the height is 1.5 times greater than the depth. These dimensions correspond to the aforementioned volumes for the device (in the form X dimension, Y dimensions, Z dimensions)

[0082] The device 100 comprises one or more physiological sensors arranged at different locations. The physiological sensors allow physiological measurements to be carried out which generate physiological data.

[0083] Physiological sensors at the extremities

[0084] In particular, in one embodiment, the device 100 comprises a physiological extremity sensor 106L at the first extremity 102L, which is referred to as the first extremity sensor 106L.

[0085] The first end sensor 106L comprises a functional surface 108L. By functional surface 108L is meant a surface intended to be positioned facing the user, to interact with the latter, with or without contact, to obtain the physiological measurement by the first end sensor 106L.

[0086] For example, the first end sensor 106L may be an electronic stethoscope, with a piezoelectric sensor and a membrane intended to be positioned on the user. The membrane functions as an amplifier of the mechanical waves generated by the heart or the lungs. In this case, the functional surface 108L comprises the membrane. The membrane is in particular the part visible to the user of the piezoelectric sensor.

[0087] For example, the first end sensor 106L may be a thermometer, with a thermopile type sensor and a lens. The lens may be surrounded by a cone. In this case, the functional surface 108L comprises the lens and, if applicable, the cone. The lens and the cone are in particular the parts visible to the user of the thermometer.

[0088] For example, the first end sensor 106L may be a spirometer with a volume and / or air flow sensor and a mouthpiece. In this case, the functional surface 108L includes the mouthpiece. The mouthpiece is in particular the part visible to the user of the spirometer.

[0089] The first end sensor 106L is positioned at the first end 102L and its functional surface 108L is inscribed in the edge 104L. This means that, in a projection along the direction of extension X in a transverse plane YZ at the end 102L, the functional surface 108L is positioned inside the edge 104L. In other words, the projection of functional surface 108L is included in the projection of the lateral face defined by the edge 106L.

[0090] Thanks to these characteristics, gripping the device 100 is not hindered by the end sensor 106L. In particular, the user can hold the device 100 by one end, with the hand (for example the palm) in line with the direction of extension. This characteristic also makes it possible to easily store the device 100, for example in a pocket or in a box.

[0091] In this regard, in one embodiment, the functional surface 108L is positioned inside the volume defined by the housing 102 (and therefore by the edge 104L at the end 102L). The end sensor 106L therefore does not protrude from the housing 102. However, for certain sensors, in particular those which require contact, such as the stethoscope, the functional surface 108L (for example the membrane) may deviate by at most 5 mm outside the volume defined by the housing 102 along the direction of extension X, or even at most 2 mm, or even at most 1 mm.

[0092] In one embodiment, the device 100 comprises a second physiological extremity sensor 106R at the second extremity 102R. This second physiological sensor 106R is defined similarly to the first physiological sensor 106L and will be referred to as the "second extremity sensor".

[0093] In one embodiment, illustrated in [Fig.l], the first end sensor 106L is an electronic stethoscope and the second end sensor 106R is a temperature sensor.

[0094] In one embodiment, illustrated in Figures 7 to 9 and which will be described later, the first end sensor 106L is a temperature sensor and the second end sensor 106R is an electronic stethoscope.

[0095] The positioning of the two end sensors 106L, 104R makes it possible to carry out these two measurements, in two different positions which will be described in the following paragraphs, with increased maneuverability and a grip which is not hindered by the end sensors 106L, 106R when the user handles the device to carry out the measurements.

[0096] The device 100 further comprises one or more physiological finger sensors 110L, 11OR arranged on the housing 102 (hereinafter called “finger sensor”). Each finger sensor 110L, 110R is intended to receive a finger of the user (index finger or thumb for example). Several embodiments will be described hereinafter.

[0097] The device 100 comprises a display 112, for example a screen (illustrated in dotted lines in [Fig.l] because the outline of the screen is invisible to the user, or at least barely visible, in this embodiment), intended to display information and / or measurement results for the user.

[0098] In one embodiment, the display 112 is configured to display information in a reading direction parallel and / or transverse to the extension direction X. In one embodiment, the device comprises a gyrometer and / or an accelerometer configured to determine the orientation in space of the device 100 and adapt the reading direction of the display 112 according to this orientation. Thus, as will be explained in more detail later, the display can be transverse when the user holds the device with one hand and longitudinal when the user holds the device with two hands.

[0099] In one embodiment, the display 112 is positioned on the front face 102F of the housing 102, such that the user can view the display 112 in the navigation position, the one-handed position, and the two-handed position. The positioning of the display 112 will be described in more detail later.

[0100] The device 100 further comprises a physical interface 114 with the user, which may take the form of a joystick (Anglicism for "navigation button" in French), an arrow, etc. The physical interface 114 is functionally connected to the display 112 and allows, for example, navigation in a menu displayed on the display 112 and selection of actions. The physical interface 114 may be positioned on the front face 102F of the housing 102.

[0101] To simplify navigation, the display 112 and the physical interface 114 are positioned side by side, for example on the front face 102F. In the embodiment of FIGS. 1 to 10, the physical interface 114 is positioned on the side of the second end 102R.

[0102] [Fig. 3] illustrates the position 300, called the navigation position. The navigation position is preferably a one-handed navigation position. This is a position during which the user uses the physical interface 114 to select a measurement. For example, for the illustrated embodiment, the user grasps the device 100 in his right or left hand, like a television remote control, by wedging the housing between the palm 304 and the fingers 306. In view of the arrangement between the display 112 and the physical interface 114, the second end 102R is arranged downwards and the first end 102L is arranged upwards. In this way, the thumb 308 naturally finds the location of the physical interface 114. This position is equally suitable for left-handed and right-handed people. In this position 300, the display 112 can be configured to display information in a reading direction transverse to the extension direction X. As illustrated here, the selection menu of available measurements (ECG, SpO2, Stetho, Thermo, for example) is for example displayed. The user can then navigate and then select the measurement he wishes to carry out with the physical interface 114.

[0103] [Fig.4] illustrates the position 400, called the one-handed manipulation position. In particular, this is a one-handed manipulation position for the first end sensor 106L at the first end 102L. In this position 400, the user holds the device 100 between the thumb and index finger (left or right hand) and places the functional surface 108L in front of the user's body (who is generally also the manipulator). In the case of the embodiment of FIGS. 1 to 6, the first sensor 106L is a stethoscope, the functional surface 108L is the membrane and the body part is the torso 402. The functional surface 108L is then in contact with the body. In this position 400, the display 112 can be configured to display information in a reading direction transverse to the extension direction X.As illustrated here, the information can be a temporal representation of the sounds picked up by the stethoscope or information about the placement of the stethoscope on the body. The user can then view the current measurement and adjust the position of the device to improve the volume of the sounds picked up.

[0104] [Fig. 5] illustrates the position 500, called the one-handed manipulation position. In particular, this is a one-handed manipulation position for the second end sensor 104R at the first end 102R. In this position 400, the user holds the device 100 between the thumb and index finger and places the functional surface 108R in front of the body. In the case of the embodiment of [Fig. 1], the second sensor 106R is a thermometer, the functional surface 108R is a lens and / or a cone and the body part is the forehead 502. The device 100 then comes in front of the forehead 502, without contact. Alternatively, the device 100 can come into contact with the forehead to measure the temperature. In this position 500, the display 112 can be configured to display information in a reading direction transverse to the extension direction X.As shown here, the temperature measurement result can be displayed.

[0105] The finger sensor

[0106] As previously indicated, the device 100 comprises a first finger sensor 110L, positioned near the first end 102L so that in the two-handed gripping position the finger sensor 110L is positioned under a finger. such position 600 is illustrated in [Fig.6].

[0107] This 100L finger sensor may comprise an electrode, for example an ECG electrode and / or an impedancemetry electrode for impedance analysis (for example impedanceplethysmogram IPG or body composition), an optical sensor (for example of the PPG, photoplethysmogram, or laser type), a force sensor, a pressure sensor, a magnetic sensor, etc.

[0108] This first finger sensor 100L can be arranged at different locations of the housing 102.

[0109] In relation to Figures 1 to 6, the finger sensor 110L is positioned so that the index finger 601L, 601R of the user is naturally positioned on it when the device is held by the first end 102L and / or the second end 102R. In this regard, the finger sensor 110L is positioned on the upper face 102T.

[0110] According to a non-illustrated embodiment, the finger sensor is positioned on the housing 102 to fall under the thumb when the device is held by the first end 102L and / or the second end 102R. In this regard, the finger sensor is positioned on the front face 102F. For example, the finger sensor may be integrated into the physical interface 114 to simplify the user interface: in [Fig.6], it is visible that the user can simply extend the thumb to reach the physical interface or the sensor may be positioned in the vicinity of the physical interface 114.

[0111] Alternatively, the finger sensor is positioned on the front face 102F, spaced from the physical interface 114.

[0112] According to an embodiment illustrated in [Fig. 10] and which will be described subsequently, the finger sensor is an electrode and the electrode is arranged on all or part of the edge 104L, 104R of the end 102L, 102R, for example via a metal deposit or an addition of a metal part.

[0113] In one embodiment, the device 100 comprises a second finger sensor 110R positioned near the second end 102R so that in position 600, of two-handed manipulation, each finger sensor 110L, 110R is positioned under a finger.

[0114] According to one embodiment, "near an end" means "between the edge of the end and strictly half the length L from the edge". According to another embodiment, "near" means "between the first edge 104L and strictly a quarter of the length L from the first edge 104L". These examples are visible in [Fig.2], with the distances L / 2 and L / 4 represented.

[0115] In one embodiment, the first finger sensor 110L and the second finger sensor 110R are electrodes, for example ECG (electrocardiogram) electrodes. The second finger sensor 110L may be positioned similarly to the first finger sensor 110R as described above, i.e. both finger sensors are on the upper face 102T (positioning symmetry visible on the upper face 102T in [Fig.2]), or both finger sensors are on the front face 102F. More generally, the first finger sensor 110L and the second finger sensor 110R may be aligned parallel to the direction of extension X. The positioning symmetry makes it possible to simplify the measurement. Alternatively, one of the two finger sensors 110L, 110R is on the upper face 102U and the other of the two finger sensors 110L, 110R is on the front face 102F. By simultaneously touching the two ECG electrodes with two fingers of different hands, the user can thus perform an ECG.

[0116] In this embodiment, the two electrodes may be spaced apart, along the extension direction X, by at least 5 cm. This distance ensures good handling without the risk of having the hands touching.

[0117] In one embodiment, only two ECG electrodes can be provided. By eliminating the third electrode often provided for performing an ECG, the handling of the device 100 is greatly simplified, since the positioning constraint only affects the fingers, which naturally fall into position.

[0118] [Fig. 6] illustrates the two-handed measurement position 600 in which at least one finger sensor 110L, 110R is used. This position consists of holding the device 100 by the ends 102L, 102R, with the hands 602L, 602R respectively. In position 600, the proximal phalanges 604L, 604R of the index fingers 601L, 601R are in the extension of the extension direction X, while the rear face 102R rests on the middle or ring fingers 606L, 606R and the thumbs 608L, 608R come to rest on the front face 102F.

[0119] When the user holds the device 100 in the two-handed manipulation position 600, the fingers are naturally placed on the finger sensors 110L, 110R. In addition, the positioning of the finger sensors also ensures that the display 112 remains clearly visible during manipulation so that the user can receive information in real time.

[0120] In this position 600, the display 112 can be configured to display information in a reading direction parallel to the extension direction X. As illustrated here, a temporal representation of the ECG being measured can be displayed. The user can then view the measurement in progress.

[0121] Furthermore, the finger sensor(s) 110L, 110R, whether on the upper face 102U or the main face 102F, are easily accessible in position 600 due to the integration of the end sensor(s) 106L, 106R in the ends 102L, 102R (being inscribed in the edge). None of the end sensors 106L, 106R generate additional (or only marginal) bulk compared to the housing 102 and does not interfere with the hand during position 600. The device 100 can therefore be quickly and easily switched between positions 300, 400, 500 with one hand and position 600 with two hands.

[0122] In one embodiment, the device 100 comprises a third finger sensor 116L positioned near the first end 102L (as illustrated in FIGS. 1 and 2) or the second end 102R so that in a two-handed gripping position the third finger sensor 116L is positioned under a finger. For example, the third finger sensor 116L is an optical sensor integrated into the electrode (for example an ECG electrode, in order to make the ECG and optical measurements at the same time). Such integration makes it possible to have the same finger position for several measurements.

[0123] In one embodiment, the device 100 includes a fourth finger sensor (not visible because positioned below the optical sensor), similarly located near the first end or the second end. The fourth finger sensor may be a force sensor, which measures a force that the finger applies to the device 100. For example, the force sensor is located below the optical sensor.

[0124] In one embodiment, the finger sensor(s) 110L, 110R, 116L are positioned within a volume defined by the housing 102. In other words, they do not extend outside the housing 102, or only slightly, for example over a distance of less than 2 mm, or, in the case of a finger sensor 110L, 110R, 116L in the physical interface 114, protrude relative to the physical interface 114. This arrangement means that the finger sensors 110L, 110R, 116L do not interfere with manipulation during positions 300, 400 and 500, for which the finger sensor 110L, 110R, 116L is not used.

[0125] Thus, the device 100 therefore allows at least two manipulation positions: a one-handed navigation position 300, one or two one-handed manipulation positions 400, 500 and a two-handed manipulation position 600. In two measurement positions, it is thus possible to carry out at least three measurements, or even four or five.

[0126] Variant for the stethoscope

[0127] In the embodiment illustrated in Figures 1 to 6, the display 112 is arranged between the navigation interface 114 and the first sensor 106L, which is a stethoscope (along the extension direction X). Thus, in position 400, that is to say in the one-handed manipulation position with the first end sensor 106L, which is here a stethoscope, the display 112 is close to the body, which may hinder reading of the display.

[0128] Figures 7 to 9 illustrate a device 700, a variant of the device 100 of the embodiment of [Fig.l]. In the device 700, the second end sensor 102R is a stethoscope. The first end sensor 102L can then be a thermometer. The remainder of the device 700 is unchanged from that of Figures 1 to 6. In this embodiment, the physical interface 114 is between the display 112 and the second end sensor 106R which is a stethoscope (along the extension direction X).

[0129] In this way, along the direction of extension X, the physical interface 114 is located between the display 112 and the stethoscope 106R (which is the second end sensor 106R). [Fig. 9] represents a position 900, corresponding to the position 400 previously described with reference to [Fig. 4], in which the use is in a one-handed position for the stethoscope.

[0130] Due to the positioning of the physical interface 114, the display 112 is further away from the second edge 104R (distance D in [Fig.9] greater than the distance D, not shown, in [Fig.4]). Thus, when the second sensor 106R (here the stethoscope) is in contact with the torso 402, the display 112 is further away from the torso 402 than in the embodiment of FIGS. 1 to 6, which makes it easier to read by limiting the angle of bending of the neck and also allowing those who have a higher body fat or higher body hair not to partially mask the display 112.

[0131] In particular, when measuring the stethoscope, the display 112 may indicate instructions to the user for the placement of the membrane 108R. It is therefore important that the user can easily see the display 112.

[0132] In addition, the portion of the housing 102 between the second edge 104R and the physical interface 114 makes it possible to hold the device 700, as illustrated in the navigation position 800, which is identical for this variant.

[0133] The user thus holds the device 700 as in position 800, illustrated in [Fig.8] (position similar to position 300 of [Fig.3]). With the physical interface 114, he selects the stethoscope measurement and then he only has to move the stethoscope directly against his torso 402, holding the device 700 between the thumb and the index / middle finger, to bring it to position 900 illustrated in [Fig.9]. The transition between position 800 and position 900 is particularly simple and does not require rotation of the device 700 in the hand. In addition, as indicated previously, the display 112 is more easily visible in this variant thanks to the distance D.

[0134] In this variant, when the first end sensor 102L is a thermometer, the position 500 of [Fig.5] may change slightly, since the hand holds the device 700 by the side opposite the thermometer 102L. Consequently, by raising the hand to the forehead, the device 700 may end up with the face 102F facing downwards, but the positioning remains simple, with no rotation of the device 700 in the hand.

[0135] Variant of the device

[0136] [Fig. 10] illustrates another embodiment of a device 1000. This embodiment is similar to the device 100, except for an end sensor 1006L, which is not inscribed in an edge as previously described. The use positions 300, 500 and 600 remain unchanged.

[0137] In [Fig. 10], it is the first end sensor 1006L that is modified, but it could be the second end sensor 1006R.

[0138] In this embodiment, an extremity physiological sensor 1006L comprises a functional face 1008L which is disposed on the front face 102F or the rear face 102R. In the illustrated example, the functional surface 1008L is positioned on the rear face 102R, on the side opposite the display 112 and the mechanical interface 114. In particular, this sensor 1006L is a stethoscope and the functional interface 1008L is a membrane. The membrane typically extends along an orthogonal plane YZ (called a “membrane plane”) to the extension direction X

[0139] However, the end sensor 1006L remains close to the end 1002L, with in particular “close to” meaning in half or a quarter of the length L of the device 1000 (same definition as previously).

[0140] The mechanical interface 114 is located on the front face 102F, between the second end 102R and half of the length L, or even a third of the length L.

[0141] The user can hold the housing 102 between the physical interface 114 and the second edge 104R to apply the membrane 1008L to the torso. In the stethoscope's use position, the extension direction X is therefore essentially parallel to the torso, whereas in position 300 of the device 100, the extension direction X is essentially perpendicular to the torso.

[0142] [Fig. 10] illustrates another embodiment of the finger sensor mentioned above. This embodiment is not directly related to the stethoscope described above.

[0143] Indeed, one or more finger sensors 1010R (only the finger sensor 1010R is concerned in [Fig. 10] but alternatively the two finger sensors 1010R, 1010L may be concerned) can be positioned on all or part of the edge 104R of the end 102R. Thus, contact is no longer made solely by the finger but also by the palm of the hand, in the two-handed manipulation position, as in position 600.

[0144] The sensor can be made by a metal deposit on the edge or by the addition of a metal part.

[0145] This embodiment is particularly suitable for the case where the finger sensor is an electrode. In the case of an optical sensor, positioning under the finger remains preferable.

[0146] Other variants

[0147] As described, combinations are possible between the given variants and embodiments.

[0148] In particular, the first end sensor as described may be at the second end and, if applicable, the second end sensor as described may be at the first end.

[0149] Presentation of the device and its environment

[0150] [Fig. 11] illustrates a diagram of the architecture of a device 100, 700, 1000 (referenced 1100 in this figure) as described and its environment.

[0151] The device 1100 comprises a control unit 1102 with control circuitry 1104 comprising a processor 1106, a memory 1008 and an I / O interface 1110 (“In / Out” in English or “Entrée / Sortie” in French) for communicating with the other components.

[0152] The memory 1008 stores programs, instructions or other things allowing both navigation on the device 1100 as well as taking measurements (algorithms in particular). The memory 10008 in particular is divided into a volatile memory 214, of the RAM type, and a non-volatile memory, of the flash type (or ROM or SSD).

[0153] The device 1100 comprises one or more sensors 1112 (all the sensors described previously are shown diagrammatically under a single reference 1112).

[0154] The control unit 1102 typically comprises an interface module 1114 interfacing between the sensors 1112 and the FO interface 1110 of the control circuitry 1104. The interface module 1114 notably comprises ADCs, filters, amplifiers, etc.

[0155] The device 1100 further comprises a display 1116, which communicates with the FO interface 1110, and a mechanical interface 1118 which communicates with the interface module 1114 for navigation in the menu of the display 1116.

[0156] To supply the various components with electrical energy, the device 1100 comprises a battery 1120, for example a cell or a rechargeable battery. The battery 1120 is configured to supply in particular the control unit 1104, the display 1114 and the sensors 1112.

[0157] Finally, for connectivity, the device 1100 comprises a wireless communication module 1122 (Bluetooth, BLE, Wifi, cellular, etc.), connected to the control circuitry 1102. The module 1122 makes it possible to communicate, via a communication network 1124, with a mobile terminal 1126 (for example a smartphone-type mobile phone) and / or a remote server 1128. The physiological data thus acquired by the device 1100 can be stored, analyzed, processed in the server 1128 and displayed by the mobile terminal 1126. The mobile terminal 1126 can also serve as a relay between the device 1100 and the server 1128 (for example in the case of a Bluetooth or BLE communication).
