Description

Title of the invention: Portable physiological measurement device technical field

[0001] The present invention relates to portable physiological measurement devices (hereinafter referred to as the measurement device), of the type of personal hand-held monitor (PHHM) incorporating a plurality of physiological data sensors. Such devices are particularly useful for remote monitoring, for example, by a physician during a teleconsultation or asynchronous consultation. In English, the terms "telehealth" or "remote patient monitoring" (RPM) are generally used. For the purposes of this 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. Previous technique

[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 electronic stethoscopes, examples include 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 physician. Furthermore, the number of measurements may be insufficient to justify a device suitable for RPM (respiratory pressure monitoring).

[0006] Among the thermometers, we can mention the one described in document WO2017114923A2 (on behalf of Withings™).

[0007] Document US2022035445 on behalf 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-shaped housing that integrates a stethoscope, an oximeter, an otoscope and a thermometer, in addition to a bra for pressure measurement.

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

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

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

[0014] For example, the Linktop 6-in-l™ product offers a device in the shape of a square mini-slab, featuring a temperature sensor and an electrode on the same 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 from a conceptual idea to a functional product on the market. Another limitation lies in the number of measurements achievable by each device: one or two measurements, and only rarely three. 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 ease of use, especially as the number of available measurements increases. Indeed, the measuring device must remain small and easy to handle for users who may be elderly or in poor health. These technical constraints have direct consequences on user adoption and retention. Summary

[0016] The description relates to measuring devices offering improved ease of use. This ease of use may relate to ergonomics. This ease of use may also relate to the number of measurements the device allows.

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

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

[0019] More specifically, the device is configured so that when the device is grasped 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 finger physiological sensor is positioned so that when grasping 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 one hand and / or a thumb of one hand.

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

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

[0023] In one embodiment, the distance along the extension direction between the first end and the second end is of a length L and "arranged close to 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 end-physiological sensor, and in particular the functional surface of the end-physiological sensor, is positioned inside 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 end-physiological sensor does not interfere with gripping the device.

[0025] The end-physiological sensor may be an audio sensor (e.g., piezoelectric) and the functional surface may include a membrane. The end-physiological 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 extension direction at the end and / or the lateral face defined by the first edge (and / or the second edge) is orthogonal to the extension direction at the end.

[0027] In one embodiment, the finger physiological sensor includes an optical sensor, for example a PPG-type sensor with LEDs or a laser. The optical sensor allows, in particular, the measurement of 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 near the first end and the device further includes a second physiological finger sensor, arranged on the housing near the second end.

[0029] For example, the first and / or second physiological finger sensor includes an electrode. For example, the electrodes are electrocardiogram (ECG) electrodes. More specifically, there may be only two ECG electrodes to perform an ECG. This arrangement simplifies the procedure for obtaining an ECG since it is sufficient to touch only two electrodes, and not three or more. Alternatively or complementarily, the electrodes may be impedance 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 includes 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 a top face arranged between the first end and the second end, the front face and the top face being connected, for example perpendicularly 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 includes a display.

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

[0036] The device may include a gyroscope and / or an accelerometer configured to determine the device's orientation in space and to adapt the display's reading direction according to this orientation.

[0037] In one embodiment, the device includes 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 the length of the housing along the extension direction from the second edge. Alternatively, the physical interface is positioned between the first edge and half, or even one-third, of the length of the housing along the extension direction from the first edge.

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

[0039] According to another aspect of this description, a method for using a device as described above is presented. The method may include the following steps: - measurement using the end-body physiological 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 include 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 comprises a step of selecting the measurement to be performed by the user 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] This description will describe several embodiments and variations of physiological measurement devices that are portable, can be grasped with one or two hands, and are suitable for self-measurement. For simplicity, the term "device" will be used. By definition, the operator is the one who holds the device, and the user is the one who undergoes the measurement. In this description, unless otherwise stated, the operator and the user are considered the same.

[0057] The device incorporates 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 the following: a temperature sensor to measure the user's body temperature, a sound sensor to measure heart or lung sounds, or an ECG sensor. (electrocardiogram) to measure heart rate and pulse, an impedance sensor, an optical sensor, of the PPG type (for "PhotoPlethysmography") for example, for oximetry, to measure blood oxygen saturation (SpO2) or other quantities such as heart rate, a force sensor, in particular to measure a force or pressure relative to the finger (ultimately to determine blood pressure), a spirometer, etc.

[0058] Physiological measurement means measurements of a user's physiological characteristics (hereafter referred to as "user") that reflect a state of health, such as: temperature, heart sounds, lung sounds, heart rate, arrhythmia, etc. In particular, in one embodiment, the device incorporates at least two physiological sensors; in another embodiment, the device incorporates at least three physiological sensors (for example: thermometer, stethoscope, ECG); in yet another embodiment, the device incorporates at least four physiological sensors (for example: thermometer, stethoscope, ECG, PPG).

[0059] By portable, we mean a device that is lightweight and compact. The device can therefore be easily grasped with one hand by a user and 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 along an extension direction, for example an essentially parallelepiped shape.

[0061] Furthermore, the device can be connected, in 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 a remote patient-referential (RPM) device, with the user becoming a patient of a remote physician. The teleconsultation can be synchronous, with live or near-live interaction with the physician, or asynchronous. In synchronous mode, the patient uses the device to acquire physiological data, which is transmitted immediately or almost immediately (within seconds). In asynchronous mode, the patient uses the device when available, and the physician accesses the physiological data when available, i.e., later.

[0062] The shape of the housing and the arrangement of the sensor(s) in the device are designed so that the device can be easily used with one hand to perform certain physiological measurements (e.g., temperature and heart or lung sounds) and with two hands to perform other physiological measurements (e.g., ECG or PPG). In one embodiment, the one-handed position may resemble a The remote control position, with which users are generally familiar, and the two-handed position can be likened to a video game console controller position, with which users are also generally familiar.

[0063] The device is intended for use in self-measurement. It must therefore be easy for a user to operate so that they can perform measurements on themselves.

[0064] However, the device must also be usable by two people, for example when one person is unable to operate the device (due to a disability or being a child, for example). Thus, the constraints related to the condition of use alone must not create constraints for use by multiple people.

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

[0066] The casing

[0067] The device 100 comprises an elongated housing 102 that defines an extension direction X. The housing 102 also defines two orthogonal transverse directions Y and Z. Hereafter, the term "transverse" is defined with respect to the X direction. This extension direction X is called the principal direction because the device 100 presents its largest dimension along this direction. The extension direction X is rectilinear in the figures, but a curvature is possible provided that the manipulation of the device would not be significantly altered.

[0068] Along the extension direction X, the housing 102 comprises a first end 102L (L for "Left") and a second end 102R (R for "Right"), 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 cross-section of the housing 102 at the first end 102L and the second end 102R).

[0069] To allow for easy gripping, each edge 104L, 104R has a length of less than 30 cm, or even 15 cm. The description will detail the different possible manipulation 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 20 cm, or even 15 cm. This distance L ensures the portability of the device 100.

[0071] In one embodiment, the distance L between the two edges 104L, 104R, along the extension direction X, is greater than 8 cm, or even 10 cm. This distance L ensures that the device is easy to grip with one hand and with two hands. Indeed, a device that is too small cannot be easily manipulated, especially by everyone.

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

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

[0074] By essentially cylindrical, it is meant that the section orthogonal to the extension direction 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, their hand(s) are primarily in contact with the housing 102. The housing 102 can be formed from several parts assembled together. In Figures 1 and 2, the housing 102 comprises two shells, labeled 102a and 102b respectively, which can be assembled at a junction parallel to the extension direction X. Alternatively, the housing 102 is formed from a single shell. Other assembly methods are possible.

[0076] At least two faces connecting edge 102L to edge 102R can be defined for the housing 102. In the case of an oblong or rectangular cross-section, the device is defined, as illustrated in [Fig. 2], as follows: a front face 102F (F for "Front"), a rear face 102R (R for "Rear") (opposite the front face), a top face 102T (T for "Top"), and a bottom face 102U (U for "Under"), opposite the top face; finally, the two edges 104L and 104R each define a lateral face. The front face 102F and rear face 102R are connected by the top face 102T and the bottom face 102U. In particular, the front face 102F and the top 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 with respect to the two-handed manipulation position illustrated in [Fig.6].

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

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

[0080] The front face 102F and rear face 102R have a length (X dimension) greater than the height (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), which 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 includes one or more physiological sensors arranged in different locations. The physiological sensors allow for physiological measurements that generate physiological data.

[0083] Physiological sensors at the extremities

[0084] In particular, in one embodiment, the device 100 includes a physiological end sensor 106L at the level of the first end 102L, which is called the first end sensor 106L.

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

[0086] For example, the first end sensor 106L can 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 lungs. In this case, the functional surface 108L includes the membrane. The membrane is, in particular, the part of the piezoelectric sensor visible to the user.

[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 includes the lens and, where applicable, the cone. The lens and the cone are, in particular, the parts of the thermometer visible to the user.

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

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

[0090] Thanks to these features, the gripping of the device 100 is not hindered by the end sensor 106L. In particular, the user can hold the device 100 by one end, with their hand (for example, their palm) in line with the direction of extension. This feature also makes it easy to 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 within the volume defined by the housing 102 (and therefore by the edge 104L at the end 102L). The end sensor 106L is therefore not projecting out of the housing 102. However, for certain sensors, particularly those requiring contact, such as a stethoscope, the functional surface 108L (for example, the diaphragm) may extend at most 5 mm out of the volume defined by the housing 102 along the extension direction X, or even at most 2 mm, or at most 1 mm.

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

[0093] In one embodiment, illustrated in [Fig.1], 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 allows these two measurements to be carried out, 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 device is handled by the user to carry out the measurements.

[0096] The device 100 further comprises one or more physiological finger sensors 110L, 110R arranged on the housing 102 (hereafter referred to as the "finger sensor"). Each finger sensor 110L, 110R is designed to receive a finger of the user (index finger or thumb, for example). Several embodiments will be described later.

[0097] The device 100 includes a display 112, for example a screen (illustrated in dotted lines on [Fig.1] 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 to 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 includes a gyroscope and / or an accelerometer configured to determine the spatial orientation of the device 100 and adapt the reading direction of the display 112 accordingly. 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 panel 102F of the housing 102, so that the user can see the display 112 in navigation position, in one-handed position, and in two-handed position. The positioning of the display 112 will be described in more detail later.

[0100] The device 100 further includes a physical interface 114 with the user, which may take the form of a joystick, an arrow, etc. The physical interface 114 is functionally connected to the display 112 and allows, for example, navigation through a menu displayed on the display 112 and the selection of actions. The physical interface 114 may be positioned on the front panel 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 figures 1 to 10, the physical interface 114 is positioned on the side of the second end 102R.

[0102] Figure 3 illustrates position 300, known as the navigation position. The navigation position is preferably a one-handed navigation position. It is a Position in which the user uses the physical interface 114 to select a measurement. For example, in the illustrated embodiment, the user grasps the device 100 in their right or left hand, like a television remote control, by wedging the casing between the palm 304 and the fingers 306. Given the arrangement between the display 112 and the physical interface 114, the second end 102R is positioned downwards and the first end 102L is positioned upwards. In this way, the thumb 308 naturally finds the location of the physical interface 114. This position is equally suitable for left- and right-handed users. In this position 300, the display 112 can be configured to show information in a transverse reading direction relative to the extension direction X. As illustrated here, the selection menu for available measurements (ECG, SpO2, Steth, Thermo, for example) is displayed.The user can then navigate and select the measurement they wish to perform with the physical interface 114.

[0103] Figure 4 illustrates position 400, known as 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 their thumb and forefinger (left or right hand) and positions the functional surface 108L in front of the user's body (which is generally also the manipulator). In the embodiment shown in Figures 1 to 6, the first sensor 106L is a stethoscope, the functional surface 108L is the diaphragm, 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 transverse reading direction relative to the extension direction X.As illustrated here, the information displayed can be a temporal representation of the sounds captured by the stethoscope, or information relating to 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 captured sounds.

[0104] Figure 5 illustrates position 500, referred to as the one-handed handling position. In particular, this is a one-handed handling position for the second end sensor 104R at the first end 102R. In this position 400, the user holds the device 100 between their thumb and forefinger and positions the functional surface 108R in front of their body. In the embodiment of Figure 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 positions itself in front of the forehead 502 without making contact. Alternatively, the device 100 can make contact with the forehead to measure the temperature. In this position 500, the display 112 can be configured to show information in a specific direction. of transverse reading relative to the X extension direction. As illustrated here, the result of the temperature measurement can be displayed.

[0105] The finger sensor

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

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

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

[0109] In relation to Figures 1 to 6, the finger sensor 110L is positioned so that the user's index finger 601L, 601R naturally rests on it when the device is held by the first end 102L and / or the second end 102R. In this respect, the finger sensor 110L is positioned on the upper face 102T.

[0110] According to an embodiment not shown, the finger sensor is positioned on the housing 102 so that it falls under the thumb when the device is held by the first end 102L and / or the second end 102R. In this respect, the finger sensor is positioned on the front face 102F. For example, the finger sensor can be integrated into the physical interface 114 to simplify the user interface: in [Fig. 6], it can be seen that the user can simply extend their thumb to reach the physical interface, or the sensor can be positioned in the vicinity of the physical interface 114.

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

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

[0113] In one embodiment, the device 100 includes 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 Another embodiment, "in the vicinity," means "between the first edge 104L and strictly one-quarter of the length L from the first edge 104L." These examples are shown 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 can be positioned similarly to the first finger sensor 110R as described above, i.e., both finger sensors are on the upper face 102T (positional 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 can be aligned parallel to the extension direction X. The positional symmetry simplifies the measurement process. Alternatively, one of the two finger sensors 110L, 110R is on the top 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 perform an ECG.

[0116] In this embodiment, the two electrodes can be spaced at least 5 cm apart along the extension direction X. This distance ensures proper handling without the risk of the hands touching each other.

[0117] In one embodiment, only two ECG electrodes may be provided. By eliminating the third electrode often required to perform 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] Figure 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 extremities 102L, 102R, with the hands 602L, 602R respectively. In position 600, the proximal phalanges 604L, 604R of the index fingers 601L, 601R are in line with the extension direction X, while the back face 102R rests on the middle or ring fingers 606L, 606R and the thumbs 608L, 608R rest on the front face 102F.

[0119] When the user holds the device 100 in the two-handed manipulation position 600, the fingers naturally fall 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 real-time information.

[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 time-based representation of the ECG being measured can be displayed. The user can then view the current measurement.

[0121] Furthermore, the finger sensor(s) 110L, 110R, whether located 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 into the ends 102L, 102R (by being embedded in the edge). Neither end sensor 106L, 106R generates any additional (or only marginal) bulk compared to the housing 102 and does not interfere with the hand in 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 includes a third finger sensor 116L positioned near the first end 102L (as illustrated in Figures 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 (e.g., an ECG electrode, in order to perform ECG and optical measurements simultaneously). Such integration allows the same finger position to be used for multiple measurements.

[0123] In one embodiment, the device 100 includes a fourth finger sensor (not visible because it is positioned below the optical sensor), located in the same way near the first or second end. The fourth finger sensor may be a force sensor, which measures the 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 from the physical interface 114. This arrangement means that the finger sensors 110L, 110R, 116L do not interfere with handling at positions 300, 400 and 500, for which the finger sensor 110L, 110R, 116L is not used.

[0125] Thus, the device 100 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 therefore possible to perform 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 positioned between the navigation interface 114 and the first sensor 106L, which is a stethoscope (along the extension direction X). Thus, in position 400, i.e., in the one-handed manipulation position with the first end sensor 106L, which is in this case a stethoscope, the display 112 is close to the body, which may hinder reading the display.

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

[0129] Thus, along the extension direction 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 stethoscope is used in a one-handed position.

[0130] Due to the positioning of the physical interface 114, the display 112 is located further 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 from the torso 402 than in the embodiment of Figures 1 to 6, which facilitates its reading by limiting the angle of neck flexion and also allowing those with a higher body fat percentage or more body hair not to partially obscure the display 112.

[0131] In particular, during stethoscope measurement, the display 112 may provide instructions to the user for the placement of the diaphragm 108R. It is therefore important that the user can easily see the display 112.

[0132] In addition, the part of the housing 102 between the second edge 104R and the physical interface 114 allows the device 700 to be held, 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] (a position similar to position 300 in [Fig. 3]). With the physical interface 114, they select the stethoscope measurement and then simply move the stethoscope directly against their torso 402, holding the device 700 between their thumb and index / middle finger, to position 900 illustrated in [Fig. 9]. The transition between position 800 and position 900 is particularly simple and does not require any The device rotates 700 degrees in the hand. Furthermore, as mentioned previously, the 112 display is more easily visible in this variant due 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, insofar as the hand holds the device 700 by the side opposite the thermometer 102L. Consequently, when raising the hand to the forehead, the device 700 may end up with the face 102F facing downwards, but positioning remains simple, with no rotation of the device 700 in the hand.

[0135] Variant of the device

[0136] Figure 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 operating positions 300, 500, and 600 remain unchanged.

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

[0138] In this embodiment, a physiological end sensor 1006L includes a functional surface 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 the "membrane plane") in the X extension direction.

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

[0140] The mechanical interface 114 is located on the front face 102F, between the second end 102R and half the length L, or even one 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 diaphragm 1008L to the torso. In the stethoscope's operating position, the extension direction X is therefore essentially parallel to the torso, whereas in the device's position 300, the extension direction X is essentially perpendicular to the torso.

[0142] Figure 10 illustrates another embodiment of the finger sensor, which was mentioned previously. This embodiment is not directly related to the stethoscope described earlier.

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

[0144] The sensor can be made by a metallic deposit on the edge or by adding a metallic part.

[0145] This embodiment is particularly suitable for cases 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 so, the second end sensor as described may be at the first end.

[0149] Presentation of the device and its environment

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

[0151] The device 1100 includes 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 other components.

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

[0153] The device 1100 includes one or more sensors 1112 (all the sensors described above are schematically represented under a single reference 1112).

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

[0155] The device 1100 further includes 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 power, the device 1100 includes a battery 1120, for example a cell or a rechargeable battery. The battery 1120 is configured to power, in particular, the control unit 1104, the display 1114, and the sensors 1112.

[0157] Finally, for connectivity, the device 1100 includes a wireless communication module 1122 (Bluetooth, BLE, Wi-Fi, cellular, etc.), connected to the control circuitry 1102. The module 1122 enables communication, via a communication network 1124, with a mobile terminal 1126 (for example, a smartphone) 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 Bluetooth or BLE communication).
