Description

[0001] This application is a divisional application. The application number of the original application is 202180018456.9, the international filing date is March 3, 2021, and the invention title is "Methods and Devices for Urine Analysis". Technical Field

[0002] The present disclosure pertains to the field of urine analysis devices positioned inside a toilet. The present disclosure also relates to a method for analyzing urine received in a toilet. Background Art

[0003] Many biological parameters are reflected in an individual's urine. For example, health problems such as urinary tract infections, diabetes, or kidney failure can be detected from urine samples. Urine samples can also reflect the quality of diet, identify the fertile period or pregnancy, and detect drug or tobacco use. Thus, there is interest in periodically monitoring various biological parameters.

[0004] It is known to provide urine analysis capabilities for toilet devices. These devices are capable of obtaining a urine sample from a toilet and analyzing the urine sample to determine the levels of biological parameters.

[0005] US5720054 and US10383606 describe collecting urine samples via a moving arm located in a toilet. However, it is difficult with this solution to collect sufficient urine without air bubbles to perform inductive analysis. In addition, the use of the moving arm adds complexity to the device.

[0006] A urine analysis device attached to the rim of a toilet is known from US20180188231. However, there still seems to be room for improvement in urine collection.

[0007] US20170284925 proposes integrating a urine sampler into a toilet bowl. Nevertheless, this solution requires adapting the toilet to install and use the device.

[0008] Therefore, there is a need for a urine analysis device that can collect urine samples from a toilet and does not have the drawbacks of the prior art. Summary of the Invention

[0009] The present specification aims to provide a urine analysis device and related method that do not have at least one of the aforementioned drawbacks.

[0010] Specifically, there is provided a urine analysis device comprising a housing configured to be fully positioned inside a toilet, the housing having a front face configured to directly receive a urine stream from a user urinating on the toilet, a rear face opposite the front face, and a collection port disposed on the front face or the rear face, wherein the housing contains a test assembly configured to perform an analysis on urine collected via the collection port.

[0011] Therefore, it is advantageous that the urine analysis device can collect urine directly via the collection port through runoff on the side of the housing. The user does not need to worry about the position of the housing when urinating in the toilet. In addition, the housing is compact enough to be fully positioned inside the toilet. It can be unobtrusive and easy to install and remove. It is also suitable for any type of toilet. In addition, the housing does not have protruding parts that are uncomfortable for the user to see and may accumulate dirt. The integrated or monolithic appearance of the outer shell gives an impression of solidity and simplicity.

[0012] Urine collection becomes easy, and the user only needs to urinate without really worrying about the positioning of the device.

[0013] The features outlined in the following paragraphs can be implemented optionally. They can be implemented independently of each other or in combination with each other.

[0014] The collection port can be in a normal use position near the lower end of the housing. For example, the collection port can be in a normal use position on the lower half of the housing. Therefore, urine flowing downward along the side of the housing due to gravity can be collected. The urine collection area is increased, and it is sufficient for a small amount of urine to reach the outer shell and drip downward along the wall of the outer shell and reach the collection port.

[0015] The housing may not have ridges. Therefore, urine can runoff along the housing without dropping or forming bubbles.

[0016] The front and / or the back may include reliefs that form a path for urine to the collection port. Whenever urine contacts the housing, it will be directed to the collection port. Therefore, the urine collection surface is increased. The reliefs can be negative (such as recesses) or positive (such as protrusions). For example, the reliefs are formed in the housing (front and / or back).

[0017] The collection port is located in a recess with a boundary. The recess has two transverse grooves extending from the edge of the housing towards the central part of the recess. The central part of the recess houses the collection port. The depth of the transverse grooves can increase from the edge towards the central part. The boundary may have an inflection point between at least one transverse groove and the central part. The distance between the boundary of the recess and the edge of the housing can increase from the starting point of the transverse groove towards the central part. The central part may have an area between 3 and 8 cm 2 between.

[0018] The recess (or the central part of the recess) can extend towards the inside of the housing by a distance between 1 and 4 cm.

[0019] The housing may have a generally circular pebble shape. Thus, the shape of the housing is defined by a curved surface and is a simple and natural shape that users like to see. Urine can flow down along the entire housing without stagnating or forming bubbles.

[0020] The urine analysis device may not have moving parts outside the housing. The urine analysis device does not require a seal. The housing has no clogging points where urine may become clogged. The urine analysis device is very hygienic.

[0021] The housing may include a discharge port configured to discharge urine. Accordingly, the excess urine collected can be swept out from the urine analysis device. Urine collection is thus not contaminated by the previous collection. Several consecutive urine collections can be performed.

[0022] The discharge port and the collection port may be equipped with a metal mesh filter. In this way, the filter can prevent the introduction of contaminants or components that may clog the test system and filter the urine before it reaches the collection port.

[0023] The housing may be made of a hydrophilic material, preferably one of the following: ceramic, polyamide, silicone, hydrophilic polymer, and / or the housing may be treated by a hydrophilic surface treatment. Thus, the urine that starts to contact the housing will adhere to and spread on the housing.

[0024] The diameter of the housing may be between 50 mm and 150 mm, preferably the diameter may be between 80 mm and 120 mm, and more preferably the diameter of the housing is about 100 mm. The housing is thus compact enough to be fully received in a toilet. The housing is discrete. The housing is also large enough to come into contact with the urine being received in the toilet over a large area.

[0025] The housing may consist of a front shell layer and a rear shell layer. The front shell layer and the rear shell layer may be joined by screwing, gluing, clamping, magnetization, or ultrasonic welding. In this way, the assembly of the housing is easier. In addition, the joining between the front shell layer and the rear shell layer may allow urine to flow between the front shell layer and the rear shell layer.

[0026] The urine analysis device may include a sensor for the presence of urine adjacent to the collection port, the sensor being configured to detect the presence of urine, preferably the sensor is a temperature sensor. Thus, the urine analysis device can start performing an analysis when urine is detected on the housing.

[0027] The urine presence sensor may be a temperature sensor. The temperature sensor can distinguish urine detected on the housing from water. In addition, the temperature sensor can detect the fertile period. Thus, the temperature sensor can detect the presence of urine and perform an analysis. The number of components of the urine analysis device is reduced.

[0028] The urine analysis device may include a fastener configured to position the housing on the inner wall of the toilet bowl. Thus, the urine analysis device can be removed or detached from the toilet.

[0029] The urine analysis device may include a module for communicating with a certain device and / or server and / or smartphone. Thus, the urine analysis device can be controlled to start performing the analysis. The urine analysis device can analyze and transmit one or more test results.

[0030] The device may include a button. The device may include a button by which the analysis can be triggered when the user presses the button.

[0031] The button may be equipped with a biometric sensor. This allows the user to be identified and the analysis to be triggered only when the user is identified. The analysis can be adapted for the identified user.

[0032] The test assembly may include one or more of the following: a plurality of test strips, a microfluidic chip, a field effect transistor, a conductivity measuring device, a pH measuring device, a spectroscopic measuring device, an electrochemical measuring device. Thus, a single housing can be adapted to analyze various biological parameters contained in urine. The urine analysis device is universal.

[0033] According to another aspect, a method of operating a urine analysis device to collect urine is provided, which includes:

[0034] - Detecting the presence of urine near the collection port;

[0035] - Collecting urine running off along the front and / or back;

[0036] - Analyzing the collected urine to establish one or more analysis results.

[0037] The features outlined in the following paragraphs may be implemented optionally. They may be implemented independently of each other or in combination with each other.

[0038] The method may be triggered by interacting with the user. The method may be triggered by pressing a button. The method may be started by detecting the user near the toilet. The method may also be started after urine is detected on the urine analysis device.

[0039] The test results may be transmitted to the user's smartphone and / or a remote server. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 1 ​​​​​​​​​​​​Figure 10 shows a toilet 10 equipped with a urine analysis device 12. In a known manner, the toilet includes a water tank 14, a bowl 16, a seat 18, and a lid 20. The urine analysis device 12 is arranged on the inner wall 16a of the toilet bowl 16. Advantageously, the urine analysis device 12 is fully received within the toilet bowl 16. In fact, the urine analysis device 12 does not protrude from the upper edge 16b of the toilet bowl and thus remains unobtrusive.

[0055] Here, the urine analysis device 12 is positioned in the path of the urine stream secreted by the user. The urine analysis device receives the urine stream when the user urinates while sitting on the toilet. The position of the urine analysis device is thus suitable for any type of user, male or female, regardless of age. Thus, the user can urinate in the toilet without having to worry about the position of the urine analysis device.

[0056] Here, the urine analysis device 12 is also positioned in the path of the flush from the tank 14. Thus, the urine analysis device can be flushed when the toilet is flushed. The urine analysis device is very hygienic.

[0057] The urine analysis device 12 includes a housing 22 that encloses a test assembly 24. The test assembly is designed to analyze the urine being received in the urine analysis device.

[0058] The housing 22 is removably arranged in the toilet bowl 16. Thus, the analysis device 12 can be removed or repositioned in the toilet. The urine analysis device is unobtrusive. In addition, the urine analysis device can be removed to recharge the battery 94 or to replenish the consumable 44 of the test assembly 24.

[0059] In Figure 2 the illustrated example, the housing 22 is arranged on the toilet wall 16a. The housing is positioned by a fastener 66. The fastener 66 includes a suction cup 88 designed to cooperate with the wall 16a of the toilet and a magnet 70. The magnet 70 is designed to cooperate with a magnet 23 (or several pieces of ferromagnetic material) arranged inside the housing. This configuration allows the housing to be easily removed or repositioned in the toilet.

[0060] In Figure 12 the illustrated example, the shape of the fastener 66 can also be circular. The fastener 66 fits into a complementary housing provided on the housing 22. The housing can be provided at the battery charging connector 94 of the urine analysis device 12. Thus, the charging connector can be protected from coming into contact with the water in the toilet 10.

[0061] Mechanical aids, including indentations, can be provided on the fastener 66. The mechanical aids can facilitate the positioning of the housing 22 when inserted into the toilet 10. The proper positioning of the housing 22 in the toilet 10 ensures the proper operation of the urine analysis device 12.

[0062] The fastener 66 may also include a ball and socket connection. The ball and socket connection allows the housing 22 to be oriented to increase the probability of contact with the urine being received in the toilet bowl 16.

[0063] Alternatively, the fastener 66 can be a hook mounted on the rim 16b of the toilet bowl 16.

[0064] General characteristics of the housing

[0065] The housing 22 has an external shape of a round pebble. In other words, the housing 22 has a flattened sphere shape. Axis A is the centerline of the housing. The housing 22 has a front face 25 and a rear face 26 that are generally perpendicular to axis A. Advantageously, the front face 25 may be generally rotationally symmetric, which provides a streamlined appearance for the device once installed. Thus, urine can be collected directly from the faces 25, 26 of the housing. The housing serves as a urine collector.

[0066] The front face 25 faces the interior of the toilet bowl 16. The front face 25 is thus intended to receive urine when the user urinates while sitting on the toilet 10. The rear face 26 faces the inner wall 16a of the toilet bowl 16. The front face 25 and the rear face 26 are connected by a curved edge 27. The respective curved edges 27 of the front and rear faces meet at the equatorial joint region. Thus, the outer surface of the housing 22 formed by the front face 25, the rear face 26, and the curved edge 27 is defined by a curve and forms a generally convex object. The housing 22 does not have a ridge. Urine can flow over the entire outer surface of the housing 22 without falling off the housing or forming bubbles, which may impair urine analysis.

[0067] A ridge can be defined as an abrupt transition between two surfaces. A curved surface can be defined as a surface having a continuous derivative and a small second derivative.

[0068] The outer surface of the housing 22 can also be white or light-colored. The color of the outer surface can be similar to the color of the toilet, making the device less conspicuous.

[0069] Generally, the housing 22 has a diameter D22 measured in a direction perpendicular to axis A between 50 mm and 150 mm. Preferably, a diameter D22 between 80 mm and 120 mm can be selected; in some embodiments, a diameter close to 100 mm can be selected. The housing 22 also has a thickness E between 15 mm and 50 mm, preferably approximately 30 mm, measured in the direction of axis A. Thus, the housing 22 is compact enough to be fully received in the toilet bowl 16 of the toilet 10. The urine analysis device 12 is discrete. In addition, the housing 22 is large enough to have a large area of contact with the urine being received in the toilet bowl 16. Thus, the user can urinate in the toilet without having to worry about the urine analysis device or aiming hurriedly.

[0070] In another aspect, in one embodiment, the housing has an overall form factor such that the E / D22 ratio is in the range of [0.2 - 0.5], and preferably in the range of [0.3 - 0.4]; these ratios are reminiscent of natural pebbles and impart a soothing appearance to the device.

[0071] The outer surface of the housing 22 is smooth. Thus, the urine flow contacting the housing 22 adheres to the outer surface of the housing and spreads over said outer surface. Preferably, the housing 22 is made of a hydrophilic material. For example, the material of the housing 22 can be one of the following: ceramic, polyamide (PA), silicone, or a hydrophilic polymer. The outer surface of the housing 22 can also be treated by a hydrophilic surface treatment, such as a hydrophilic polymer from Aculon, or

[0072] as Figure 4 more clearly seen in, according to a particular embodiment, the housing 22 is formed as a combination of two half - shells and consists of a front shell layer 28 and a rear shell layer 30. The front shell layer 28 and the rear shell layer 30 form an annular joint 31 (also referred to as an edge 31) of the housing 22 in a plane perpendicular to the axis A. When the housing 22 consists of the front shell layer 28 and the rear shell layer 30, it facilitates the assembly of the urine analysis device 12.

[0073] The front shell layer 28 and the rear shell layer 30 are joined together to hold the outer surface of the housing 22 defined by the curve. Thus, the annular joint 31 between the front shell layer and the rear shell layer allows urine to flow between the front 25 and the rear 26. The influence of the joint 31 on the urine flow on the housing is minimized.

[0074] The front shell layer 28 and the rear shell layer 30 can be assembled by screwing, gluing, clamping, magnetization, or ultrasonic welding. Of course, other fastening means can be used to assemble the front shell layer 28 and the rear shell layer 30.

[0075] For example, the front shell layer 28 and the rear shell layer 30 are screwed together. Thus, the inner part of the front shell layer 28 includes threads. The threads of the front shell layer 28 are designed to cooperate with the complementary threads of the rear shell layer 30. This allows for easy disassembly of the housing 22 to access the test assembly 24 inside the housing.

[0076] In another example, the inner part of the rear shell layer 30 includes threads 140 designed to cooperate with the threads of the front shell layer 28. The two shell layers 28, 30 are assembled by screwing. Alternatively, the combination of the two shell layers 28, 30 can be a bayonet system.

[0077] A seal may be present at the junction 31 between the front shell layer 28 and the rear shell layer 30. Thus, the outer shell 22 is waterproof. The interior of the housing 22 cannot be penetrated by urine, water from the water tank 14 or the cylinder 16, and any other type of contaminants. Only the collection port and the discharge port connect the exterior and the interior of the housing, as described in more detail below.

[0078] Other functions supported by the device

[0079] In Figure 5 In the illustrated example, a removable cover 90 is disposed on the rear shell layer. The removable cover allows easy access to the test assembly 24. Specifically, the removable cover allows the refill of the consumables 44 of the test assembly 24.

[0080] Here, the removable cover 90 is attached to the rear shell layer 30 by a clamping, screwing, or bayonet mechanism. Of course, other attachment means may be implemented to secure the removable cover to the rear shell layer 30. Alternatively, in another example, the removable cover may be attached to the front shell layer 28.

[0081] The removable cover 90 is disposed in a sealed manner. For example, the junction between the removable cover and the rear shell layer 30 may include a seal. Thus, the interior of the housing 22 cannot be penetrated by urine, water from the water tank 14 or the cylinder 16, and any other type of contaminants.

[0082] In another example, the removable cover 90 is formed by the front shell layer 28 of the housing 22. Thus, the removable cover 90 can be removed by unscrewing the front shell layer 28 from the rear shell layer 30. The housing 22 has fewer junctions that may be contaminated and / or wetted by the water in the toilet bowl.

[0083] The housing 22 has a collection port 32. The collection port can receive urine flowing on the outer surface of the housing 22 due to gravity. Urine is collected directly from the sides 25, 26 of the housing.

[0084] The collection port 32 is located on the lower end 36 of the housing. When the housing 22 is positioned in the toilet bowl cylinder, the lower end 36 faces the bottom of the toilet bowl cylinder 16. This position corresponds to the normal use position. This position allows urine to be collected by gravity on most of the outer surface of the housing.

[0085] In the present case, the distance D between the collection port 32 and the lower edge 22a of the housing 22 is less than 40 mm, preferably less than 20 mm. According to a specific embodiment, the collection port 32 is arranged a few millimeters above the bottom edge of the outer housing. Alternatively, the collection port may be on the bottom edge 22a.

[0086] The collection port 32 is an opening, typically circular, with a diameter preferably between 0.3 mm and 2 mm. The diameter of the collection port can be selected to maximize the volume of urine collected from the outer surface of the housing.

[0087] The housing 22 has a discharge port 34. The discharge port allows excess urine to be flushed from the urine analysis device.

[0088] The discharge port 34 can be separated from the collection port 32. Thus, the discharge port is also located at the lower end of the housing 22, near the collection port. The discharge port is also a circular opening. The discharge hole 34 has a diameter between 0.3 mm and 2 mm. In the normal use position, as Figure 7 shown in the embodiment, the discharge port can be below the collection port.

[0089] The discharge port 34 can also be located away from the collection port 32. The position of the discharge port 34 can be selected to facilitate access to the discharge port by the test assembly 24. For example, Figure 13 this discharge port 34 is shown. This will be described in more detail below.

[0090] Alternatively, as Figure 5 shown, the discharge port 34 can be the same as the collection port 32. A single port limits the number of openings into the interior of the housing 22. Thus, the risk of introducing contaminants or components that could clog the test assembly 24 is reduced.

[0091] As Figure 6 can be seen, the tops of the collection port 32 and the discharge port 34 can be covered with a metal mesh filter 92. The filter covers ports 32, 34. The screen filter 92 is, for example, oval in shape and covers ports 32, 34. The typical mesh of the filter 92 is, for example, 20 microns. The filter 92 prevents the introduction of contaminants or components that could clog the test assembly 24 and filters the urine received in the collection port 32. Alternatively, the filter 92 can be cleaned by an air stream generated by an air pump. In one embodiment, only the collection port 32 is protected by the metal mesh filter 92. The discharge port 34, due to its arrangement, function, and the flow rate of its jet, is less likely to contaminate the collection port 32.

[0092] Specifically, in Figures 2 to 7 In the example shown, the collection port 32 and the discharge port 34 are located on the rear 26 of the housing. Thus, when the urine analysis device 12 is positioned in the toilet 10, the collection port and the discharge port face the wall 16a of the toilet bowl 16. This position allows the collection port and the discharge port to be hidden by the front 25 of the housing and not visible for use. The front visible to the user is similar to the simple and uniform pebbles as already mentioned, without any individual points or holes, which gives the urine analysis device a somewhat curious appearance (it looks very simple but produces very complex results). And, it should be noted that this positioning prevents the introduction of contaminants or components that may block the test assembly 24.

[0093] The collection port 32 and the discharge port 34 are located in the recess 37. The recess 37 is formed on the housing 22, specifically on the rear 26. The recess extends inwardly from the housing 22 by a maximum distance between 1 and 4 cm, for example between 1.5 and 3 cm. The recess 37 has two transverse grooves 39 that extend from the rear 31 of the housing towards the central portion 43 of the recess 37 having the openings 32, 34. The depth of the transverse groove 39, that is, the distance from the rear 26 to the interior of the housing 22 in the direction of the axis A, increases from the rear 31 towards the central portion 43. Thus, the recess 37 forms a urine path from the front 25 to the collection port 32. Advantageously, the recess 37 allows urine flowing down along the front 25 to be collected and directed to the collection port. Thus, the volume of urine reaching the collection port from the front 25 of the housing is sufficient to meet the needs of the analysis.

[0094] The central portion 43 of the recess 37 serving as a buffer pool generally extends inwardly from the housing by a distance between 1 and 4 cm, for example between 1.5 and 3 cm. Horizontally, these same dimensions of the central portion 43 are applicable. In one embodiment, the area of the central portion 43 of the recess is at least 3 cm 2 and less than 8 cm 2 . In this way, the recess 37 and specifically the central portion 43 of the recess 37 form a buffer pool (open outwardly) that can receive urine that has run off along the device, thereby ensuring that the collection port 32 receives urine.

[0095] The recess 37 can extend across the entire lower half of the device 12. Assuming the device 12 has a spherical shape, it is possible to angularly define each point of the joint 31 around the axis A. By defining the collection port 32 as angle zero, the position of the joint 31 from which the groove 39 is formed can be at 90° (on both sides), or between 80 or 90°. Or, for example, as Figure 13As shown, the position can be closer to the collection port 32 and can be between 20° and 55°. As for the central part 43, it is positioned at less than 20°. Thus, depending on the position of the starting point of the groove 39 on the joint 31 (such as 90°, 80°, 55° or 20°, etc.), the groove 39 is longer or shorter.

[0096] In Figure 13 In one embodiment shown, for example, only the collection port 32 is in the recess 37. The discharge port 34 is located on the rear 26, outside the recess 37 (usually between 20 and 40°). In the normal use position of the device 12, the discharge port 34 is thus higher than the collection port 32. The spacing between the two ports 32, 34 makes the recess 37 neater. In addition, it has been observed that the discharge port 34 arranged in this way does not cause contamination of the collection port 32.

[0097] The boundary 40 defining the recess 37 is rounded. In other words, the boundary 40 is defined by a curved surface. The edge 40 does not have a ridge. Urine in contact with the rear 26 can run off to the collection port 32 without falling from the housing or forming air bubbles. Thus, the volume of urine reaching the collection port from the rear of the housing increases. The absence of a ridge is verified along the boundary 40 (along a line) and also perpendicular to the boundary 40 (also along a line). In other words, the three-dimensional surface defining the recess 37 (and including the boundary 40) does not have a ridge. This means that there is no ridge in the transition from the rear 30 to the boundary 40 and no ridge in the transition from the boundary to the interior of the recess.

[0098] In an exemplary embodiment, the collection port 32 is positioned 8 mm below the boundary 40.

[0099] The boundary 40 of the recess 37 can have an inflection point between each transverse groove 39 and the central part 43, such that, following the edge of the recess 37, the transverse groove 39 is convex (defining convexity from the perspective of the material of the device rather than from the perspective of the negative space complementary to the device), and then the inflection point forms and the central part 43 is concave, and then another inflection point forms and another transverse groove 39 is convex. Alternatively, the boundary 40 of the recess 37 does not have an inflection point and remains convex.

[0100] For the purpose of use (i.e., the urine analysis device 12 is horizontally placed in the middle on the inner wall 16a of the cylinder 16a), the recess 37 is generally symmetric. However, the recess can have a slight asymmetry to facilitate installation on the slightly left or right side of the inner wall 16a of the cylinder 16, and the collection port 32 can be slightly positioned on the right or left side (such that in use, the collection port 32 is generally horizontally centered on the inner wall 16a of the cylinder 16).

[0101] The distance between the boundary 40 and the lower edge of the device 12 (i.e., the distance between the segment intersecting the boundary 40 and the lower edge of the device, the segment being orthogonal to the tangent of the edge at the intersection point) increases from the position of the junction 31 from which the transverse groove extends (i.e., the starting point of the transverse groove) towards the central part 43.

[0102] Alternatively, in Figure 8 the illustrated example, the collection port 32 integrated with the discharge port 34 is located on the front face 25 of the housing. Thus, urine flowing down along the front face reaches the collection port more directly.

[0103] As shown, the collection port 32 is on the protrusion 52 of the front face 25. The protrusion 52 extends from the junction 31 towards the lower end 36 of the housing having the port 32. The protrusion also forms a path for urine from the junction 31 of the housing to the collection port 32. The protrusion allows urine dripping from the front face 25 to be collected and directed towards the collection port.

[0104] It should be noted that the collection port may have an upwardly directed mouth, or a downwardly directed mouth, not excluding a completely radially directed mouth (i.e., flush with the overall surface of the outer casing).

[0105] The housing 22 is not limited to the implementation modes described above with respect to the figures, but on the contrary, admits many variations achievable by those skilled in the art.

[0106] Specifically, the housing 22 can take any geometric shape defined by curves. Specifically, the housing can have a rhombus or an inverted teardrop shape. In this case, the housing has a point on the lower part for guiding urine towards the collection orifice 32.

[0107] The collection port 32 and the discharge port 34 (if present) can be located on positive reliefs such as protrusions or on negative reliefs such as grooves or recesses. Generally speaking, the relief can be any geometric structure that allows urine to flow above the housing 22 and be directed towards the collection port 32 without falling from the housing or forming air bubbles.

[0108] In one embodiment, the collection port 32 is arranged on the front face 25, while the discharge port 34 is located on the rear face 26.

[0109] Test assembly

[0110] Subsequently, the test assembly 24 will be described in more detail with reference to Figure 9 more specifically.

[0111] The test assembly 24 is controlled by an electronic control unit 45. The electronic control unit 45 is within the housing 22. The electronic control unit 45 controls the components of the test assembly to perform urine analysis and obtain one or more test results.

[0112] The test assembly 24 includes an analysis system 50. The analysis system 50 performs an analysis on urine collected from the collection port 32 to establish one or more results. Here, the analysis can be one or more of the following:

[0113] - Analysis using colorimetric strips of conventional or lateral or vertical flow immunoassay types: Urine is received on a strip containing one or more reagents sensitive to one or more components of urine, and an analysis based on optical detection is used to obtain the analysis result;

[0114] - Analysis using a microfluidic chip of the "lab on a chip" type: The chip mixes urine with one or more reagents contained in microdrops, and an analysis based on optical detection makes it possible to obtain the analysis result;

[0115] - Analysis using a microfluidic chip on a porous support: The mixing of urine with one or more reagents is achieved by capillary action;

[0116] - Analysis using a field effect transistor, as described in the published patent application Withings EP3562407;

[0117] - Analysis by urine conductivity measurement;

[0118] - Analysis by measuring pH using a metric pH probe;

[0119] - Analysis by spectrophotometric measurement;

[0120] - Analysis by electrochemical measurement.

[0121] The test assembly 24 includes a urine delivery member 48. The urine delivery member 48 allows urine to be delivered from the collection port 32 to the discharge port 34 via the analysis system 50. Preferably, the urine delivery member 48 includes a collection channel 82, a flushing channel 84, and a pump 86.

[0122] The collection channel 82 connects the collection port 32 to the analysis system 50. The collection channel 82 allows urine to be transported from the collection port 32 to the analysis system 50.

[0123] The flushing channel 84 connects the analysis system 50 to the discharge port 34. Specifically, the flushing channel allows the urine contained in the urine delivery member 48 to be emptied. Preferably, the flushing channel 84 is hydrophobic, thus allowing better emptying of urine. Therefore, the risk of contamination of the urine transported between two consecutive collections is reduced.

[0124] The pump 86 is arranged between a first part 82a and a second part 82b of the collection channel 82.

[0125] The pump 86 can draw urine from the collection port 32. For example, the pump 86 aspirates between 5 microliters and 1 mL, preferably about 20 microliters. Subsequently, the pump can deliver a sufficient volume of urine to perform an inductive analysis. The aspiration rate of the pump is selected according to the diameter of the collection port. Thus, the pump can draw urine from the collection port into the analysis system 50 without forming air bubbles.

[0126] The pump 86 can also draw air from the collection port 32. The air flows through the urine delivery member 48 to the discharge port 34 to discharge the urine contained in the urine delivery member. Thus, the urine collected for analysis is protected from possible contamination from a previous collection.

[0127] Alternatively, the pump 86 can draw water after initiating the flush of the toilet 10 to discharge the urine contained in the urine delivery member 48.

[0128] Here, the pump 86 is a piezoelectric pump. By using a piezoelectric pump, the urine analysis device can be free of controlled valves, which can simplify the urine analysis device.

[0129] Alternatively, the pump can be a pneumatic system. Thus, the pneumatic system is configured to form a negative pressure to draw urine from the collection port and a positive pressure to push the urine to the analysis system 50 and the discharge port. This solution allows for precise control of the volume collected by the urine analysis device 12.

[0130] The test assembly 24 includes a urine presence sensor 38. The urine presence sensor 38 is disposed near the collection port 32. The urine presence sensor then detects when urine is present near the collection port.

[0131] According to one embodiment, the urine presence sensor 38 can form a loop around the collection port. The integration of the urine presence sensor into the urine analysis device is thus discrete.

[0132] Preferably, the urine presence sensor 38 is a temperature sensor, such as a thermistor. This is because the temperature sensor can distinguish urine from water from the toilet 10. In addition, the temperature sensor can also be used to measure the temperature of the urine. Specifically, the temperature of the urine can be used to detect the fertile period. The use of the temperature sensor thus reduces the number of components operated by the test assembly 24 to perform the analysis. The complexity and cost of manufacturing the urine analysis device are reduced.

[0133] Alternatively, the urine presence sensor 38 can be any type of liquid sensor, such as a capacitive or resistive sensor. Thus, the temperature sensor is separated from the urine presence sensor. The temperature sensor can be dedicated to measuring the temperature of the urine, specifically for detecting the fertile period.

[0134] Communication and system aspects

[0135] The urine analysis device includes a communication module 41. The communication module 41 is wireless. The communication module 41 operates a local area network, such as Bluetooth, Bluetooth Low Energy (BLE), or Wi-fi. The local area network allows the battery 94 of the test assembly 24 to be conserved. Thus, the autonomy of the analysis device 12 is increased.

[0136] Alternatively, the communication module 41 can operate a cellular telecommunications network. The cellular telecommunications network can be, for example, GSM, 3G, 4G, 5G, 4G-LTE. The communication module 41 thus has a longer range.

[0137] Alternatively, the communication module 41 can operate a gateway connected to a cellular telecommunications network. Specifically, the gateway can be a router (e.g., a Wi-fi router connected to the cellular network), a hub (i.e., a device directly connected to the cellular network), or the user's smartphone. Thus, the urine analysis device 12 can be connected to the cellular network without affecting the battery life 94.

[0138] Preferably, the communication module 41 communicates with the user's smartphone 61 using Bluetooth Low Energy (BLE) technology and connects to the remote server 98 using Wi-Fi technology.

[0139] The communication module 41 allows the analysis to be triggered via remote control.

[0140] Preferably, the analysis is initiated from the user's smartphone 61. The user can initiate the analysis from an application on the smartphone. The user can control the urine analysis device 12 and can select when to perform the analysis. The user can also be identified by using the smartphone. The analysis performed is thus customized for the user. The user can also select which tests they wish to perform.

[0141] Alternatively, the analysis is initiated by communicating with a remote device 42 near the toilet. The remote device has a button 55. The user can then press the button to initiate the analysis. The user can control the urine analysis device and can select when to perform the analysis.

[0142] The button 55 can be equipped with a biometric sensor 57. The button can thus identify that the button has been pressed by the user. Then, an analysis related to the identified user can be performed by the urine analysis device. In addition, the analysis performed can be selected based on the identified user, and the results can be sent to enrich the medical history of the identified user.

[0143] The remote device 42 also includes a display 59. For example, the display can consist of one or more colored light-emitting diodes (LEDs). The display can also include a screen. The display can notify the user. For example, the user can be informed that the button press has been detected, and / or the user has been identified, and / or the analysis is about to be performed.

[0144] Alternatively, the remote device 42 can be a connected wristband associated with the user. In this case, when the user is near the toilet, the user can be automatically detected. The user can also be identified through the connected wristband. Therefore, the analysis can be automatically started without any action by the user. It should be noted that the connected wristband can be a connected watch.

[0145] The communication module 41 is also used to transmit test results. The test results can be one or more of the following: fertility, pregnancy, urinary tract infection, liver problems, kidney failure, uric acid poisoning, dehydration, heart disease, and / or diabetes. The results can also be an indicator of medication compliance.

[0146] The communication module 41 can directly send the test results to the display 59 or the smartphone 61. The communication module can thus not have a connection to the cellular telecommunications network. The test results can be locally interpreted by the electronic control unit 45 or by a smartphone application. Therefore, the operating cost of the urine analysis device 12 is reduced.

[0147] Alternatively, the communication module 41 can send the one or more results to the remote server 98. The remote server 98 can interpret the results. The operation server reduces the amount of computation required to locally interpret the test results.

[0148] The remote server 98 can also have storage capabilities. Therefore, the remote server can store the results of multiple consecutive analyses.

[0149] The user can view and utilize one or more results received directly from the analysis device 12 or spoken by the server. For example, the user can view and utilize the results from a smartphone application. Alternatively, the user can access a website with a computer.

[0150] The housing 22 can include one or more indicator lights (e.g., light-emitting diodes, i.e., LEDs), which are arranged inside the housing opposite the translucent portion of the front of the housing, in order to provide visual feedback to the user regarding the operation of the analysis device 12. Various colors and flash patterns can be provided to indicate various device states to the user.

[0151] Finally, the user can access the button 192 from the housing 22. The user can access the button 192 to reset the urine analysis device 12. Specifically, when the removable cover 90 is removed, the user can access the button 192.

[0152] Electronic control unit

[0153] Preferably, the control unit is built from a system-on-chip. A first Bluetooth Low Energy chip can control the electronic components of the urine analysis device. The first BLE chip can also support communication with nearby devices. A second Wifi chip can support data exchange with a remote server. Thus, the second system-on-chip can be disconnected when communication with the server is not in use. The power consumption of the control unit is improved and the battery consumption is reduced.

[0154] The control unit can also be divided into different circuit boards. Each circuit board can control different electronic components of the urine analysis device. The main circuit can ensure the cooperation between different circuit boards. This configuration allows for flexibility in the construction of the electronic control unit and its integration into the housing.

[0155] The electronic control unit 45 is powered by a battery 94 disposed inside the housing 22. The battery 94 is of the lithium-ion type. The capacity of the battery is approximately 1080 mAh. This capacity makes it possible to ensure satisfactory autonomy of the device without compromising the dimensions of the housing.

[0156] The battery 94 includes a charging connector 54. As can be seen in particular Figure 13 here, the charging connector 54 can be accessed from outside the housing 22 to allow the battery 94 to be recharged. For example, the housing 22 can be placed on a stand to connect the charging connector 54 to a power source. Alternatively, inductive charging can also be considered.

[0157] Process aspects

[0158] Below, two processes for initiating the urine analysis and receiving the results are described in more detail. These processes are implemented by the electronic control unit 45.

[0159] In Figure 10 the example shown, the implementation process is initiated by interacting with the user.

[0160] In step E0, the urine analysis device 12 is in an inactive state. In the inactive state, the urine analysis device is waiting to receive a request for analysis.

[0161] Thus, step E1 corresponds to the reception of an analysis request. The analysis request can come from the user pressing a button 55. The analysis request can also be issued from a smartphone 61. The analysis request can also be automatically executed when the user is located near the toilet 10. The display 59 can indicate to the user that his support has been received. The display can also indicate whether the user is recognized when the button is pressed.

[0162] In step E2, the urine analysis device 12 enters an active state. In the active state, the urine analysis device waits to detect urine near the collection port 32. The housing 22 can be further equipped with an LED to alert the user that the urine analysis device is in the active mode.

[0163] If no urine flow is received within a specified time period, the urine analysis device 12 returns to the inactive state of step E0. However, if a urine flow is detected, the pump 86 is activated to deliver urine from the collection port 32 to the analysis system 50 (step E3).

[0164] Step E4 involves performing an analysis on the collected urine. The analysis performed depends on the analysis device 50 in the housing 22. The analysis performed may also depend on the user identified by the button 55. The analysis performed may also depend on the selection made by the user.

[0165] Step E5 corresponds to transmitting the results. The results can be directly transmitted to the user. The results can also be sent to the server 98. For example, the user can view and evaluate the results on the smartphone application 61 or on a website. The results can also be sent to a healthcare professional.

[0166] Finally, step E6 is to activate the pump 86 to flush excess urine from the urine analysis device 12. The urine analysis device then returns to the inactive state of step E0.

[0167] Alternatively, in Figure 11 the example shown, the process is initiated when urine is detected on the housing 22.

[0168] In step E100, the urine analysis device 12 is in an inactive state. Here, the inactive state corresponds to waiting to detect urine near the collection port 32.

[0169] Next, step E101 is to detect the presence of urine near the collection port.

[0170] In step E102, the pump 86 is activated to draw urine from the collection port into the analysis system 50. The display 59 can indicate that it is ready to perform the analysis. Alternatively, the housing 22 with an LED can indicate that it is ready to perform the analysis.

[0171] In step E103, the urine analysis device 12 waits to receive an analysis request from the user. The analysis request can originate from the user pressing the button 55. The analysis request can also be issued from the smartphone 61.

[0172] If no analysis request is received within a specified time period, the pump 86 is activated to flush the collected urine from the urine analysis device 12 (step E106). The urine analysis device returns to the inactive state of step E100.

[0173] However, if an analysis request is received, the analysis is performed at step E104. In addition, the display 59 can indicate to the user that their press has been received. The display can also indicate whether the user is identified when the button 55 is pressed.

[0174] Step E105 corresponds to the transmission result. The result can be directly transmitted to the user. The result can also be sent to server 98. For example, the user can view the result on the smartphone application 61 or on a website. The result can also be sent to a healthcare professional.

[0175] Finally, step E106 is to activate pump 86 to flush excess urine from urine analysis device 12. The urine analysis device then returns to the inactive mode of step E100.
