Description
Title of the invention: Device and method for urine analysis Technical field
[0001] The present disclosure relates to the field of urine analysis devices intended to be positioned inside a toilet. The present disclosure also relates to a method for analyzing urine being received in a toilet. Prior art
[0002] Many biological parameters are reflected in an individual's urine. From a urine sample, it is for example possible to detect health problems such as a urinary tract infection, diabetes or kidney failure. The urine sample can also reflect the quality of a diet, identify a period of fertility or pregnancy and detect drug or tobacco use. It is therefore interesting to monitor various biological parameters periodically.
[0003] It is known to propose devices installed in toilets having a urine analysis function. These devices are capable of taking urine samples from the toilets and analyzing them in order to determine the level of a biological parameter.
[0004] Document US20180188231 discloses a urine analysis device to be fixed to a toilet rim. This device allows an analysis to be carried out with a field effect transistor.
[0005] Documents US20170284925 and US 10383606 propose devices comprising test strips passing in front of an analysis section.
[0006] However, such devices are bulky. In particular, they require a storage area for new and used test strips. These devices must then be positioned largely outside the toilet or must be integrated into it.
[0007] Furthermore, such devices are not flexible. It appears particularly difficult to refill new test strips and remove used strips. It also appears difficult to carry out analyses requiring several types of strips.
[0008] There is therefore a need for a urine analysis device which does not have the drawbacks of the prior art.
[0009] Disclosure of the invention: A urine analysis device is provided for positioning inside a toilet comprising a test assembly comprising: - at least one rotating support comprising a plurality of test strips fixed on the rotating support; - an injector configured to inject a controlled volume of urine onto at least one of the test strips; - an analysis system configured to detect a urine injection result on the test strip.
[0010] Thus, advantageously, the urine analysis device is sufficiently compact to be positioned entirely inside the toilet. It can then be discreet and be installed and removed easily. It can also adapt to any type of toilet. The use of a rotating support on which the strips are fixed makes it possible to carry out a plurality of analyses very simply. The use of such a rotating support makes it possible to reduce the size of the device for a given number of analyses. The rotating support can also be replaced. The device is thus modular and versatile.
[0011] By 'rotary support', it is meant here that the support is a part mounted to rotate on a part forming a base.
[0012] The features set out in the following paragraphs may optionally be implemented. They may be implemented independently of one another or in combination with one another.
[0013] The or each rotating support may be configured to rotate a test strip and selectively present it in front of the injector and / or in front of the analysis system. This reduces the number of moving parts in the device. It also appears possible to select a specific type of strip to perform an analysis. The device is versatile and modular.
[0014] The or each rotating support may be configured to rotate in the direction clockwise and counterclockwise. Thus, the test strip can be presented in front of the injector and / or the analysis system along the shortest path. This arrangement also allows great flexibility in the design of the device, in particular by reducing constraints regarding the positioning of the analysis system or the injector in relation to the rotating support.
[0015] The or each rotating support may comprise housings receiving one or more test strips. This keeps the test strips in the rotating holder. Each slot can separate one or more test strips from neighboring test strips, improving strip preservation and analysis accuracy.
[0016] The housings may be closed by at least one cover, preferably transparent or translucent. Thus, reagents contained in the test strips are preserved before analysis. They can be easily analyzed by the analysis system, in particular by optical analysis.
[0017] The rotary support may be cylindrical, and the housings may be arranged on a outer wall of the rotating holder. This configuration maximizes the number of test strips received in the rotating holder slots. A large number of analyses can be performed without having to reload the device with test strips.
[0018] In one variant, the housings may be provided on an internal wall of the cylindrical rotating support. This arrangement allows great flexibility in the design of the device, in particular by reducing the constraints regarding the positioning of the analysis system or the injector relative to the rotating support.
[0019] The rotating support may comprise one or more markers, the device may comprise a sensor configured to detect the markers. Thus, the device can precisely control the angular position of the rotating support.
[0020] The markers may be optical markers, for example lines or barcodes. The sensor may then perform an optical analysis to establish the position of the rotating support. In addition, the optical sensor may identify a type of test strip. The sensor may also be the same as that of the analysis system. As a result, the complexity of the device is reduced, by reducing the number of components used during its operation.
[0021] The injector may be configured to inject between 1 microliter and 20 microliters of urine onto a test strip, preferably between 2 microliters and 4 microliters. Then, the injector injects enough urine onto a test strip to perform a conclusive analysis.
[0022] A housing may enclose the test assembly, the housing being configured to be entirely positioned inside a toilet, in particular inside a toilet bowl, against an interior wall of said bowl. The housing then protects the test assembly from the outside. The device is devoid of moving parts outside the housing. Thus, the urine analysis device is discreet. The housing is also devoid of stagnation points where urine could stagnate. The urine analysis device is hygienic. The housing is also devoid of moving parts outside the housing, and therefore devoid of a rotating joint, which is problematic in the environment considered.
[0023] The rotating holder may be removably arranged in the housing. Thus, a user may remove the rotating holder to replace it, for example to refill the device with test strips or change the type of test strips.
[0024] The housing may have a front face intended to receive a jet of urine directly from a user urinating while seated on the toilet, a rear face opposite the front face, and a collection orifice, arranged on the front face or on the rear face. The collection orifice may also be located at a boundary between the front face and the rear face. Thus, advantageously, the urine analysis device may Collect urine through the collection port directly by running it through the box. A user does not need to worry about the position of the box when urinating in the toilet.
[0025] The housing may include a drain port configured to drain urine. Then, excess collected urine may be purged from the previously collected urine analysis device. A subsequent urine collection is then not contaminated by a previous collection. Multiple consecutive urine collections may be performed.
[0026] The housing may have a general shape of a circular pebble. Thus, the shape of the housing is defined by curved surfaces. Urine may run over the entire housing without detaching or forming air bubbles.
[0027] The urine analysis device may comprise a urine presence sensor, in the vicinity of the collection orifice, the sensor being configured to detect the presence of urine, preferably the sensor being a temperature sensor. Thus, the urine analysis device may trigger an analysis when urine is detected on the housing.
[0028] The urine presence sensor may be a temperature sensor. The temperature sensor can distinguish between urine and water being detected on the housing. In addition, the temperature sensor can detect a fertile period. Then, the temperature sensor can both detect the presence of urine and perform an analysis. The number of components of the urine analysis device is reduced.
[0029] The urine analysis device may comprise a communication module with a remote device and / or a server and / or a smartphone. Thus, the urine analysis device may be controlled to trigger an analysis. The urine analysis device may analyze and transmit one or more analysis results.
[0030] The remote device may include a button. Then, an analysis may be triggered when a user presses the button.
[0031] The button may be provided with a biometric sensor. Then, the user can be identified and the analysis only starts if a user is identified. An analysis can be adapted to the identified user.
[0032] According to another aspect, there is provided a urine analysis method using the urine analysis device, comprising: - position a test strip in front of the injector by rotating the rotating support; - inject a controlled volume of urine onto the test strip; - position a test strip in front of the analysis system by rotating the rotating support; - analyze the test strip to establish an analysis result, preferably by optical analysis.
[0033] The characteristics set out in the following paragraphs may, optionally- ally, be implemented. They can be implemented independently of each other or in combination with each other.
[0034] The method may be triggered by a prior step of interaction with a user. The method may be triggered by pressing a button. The method may be initiated by detecting a user near the toilet. The method may also be initiated upon detection of urine on the urine analysis device.
[0035] A user can select an analysis. For example, a user can choose the type of analysis they wish to perform.
[0036] The analysis result can be transmitted to a user's smartphone and / or a remote server. Brief description of the drawings

[0054] [fig.17] illustrates a flowchart of a second method of using the urine analysis device. Description of the embodiments
[0055] Figure 1 illustrates a toilet 10 equipped with a urine analysis device 12. In known manner, the toilet comprises a water tank 14, a bowl 16, a seat 18 and a cover 20. The urine analysis device is arranged on an internal wall 16a of the toilet bowl. Advantageously, the urine analysis device 12 is entirely received in the toilet bowl. Indeed, the urine analysis device is discreet.
[0056] Here, the urine analysis device 12 is positioned on the path of a urine stream secreted by a user. The urine analysis device 12 receives a urine stream when a user urinates while sitting in the toilet. The position of the urine analysis device is then suitable for any type of user, male or female, regardless of age. The user can then urinate in the toilet without worrying about the position of the urine analysis device.
[0057] Here, the urine analysis device 12 is also positioned in the path of a flush from the cistern 14. Thus, the urine analysis device can be rinsed when the flush is actuated. The urine analysis device is hygienic.
[0058] The urine analysis device 12 comprises a housing 22 enclosing a test assembly 24. The test assembly 24 is for analyzing urine being received in the urine analysis device 12.
[0059] The housing 22 is arranged in the toilet bowl 16 in a removable manner. The analysis device can then be removed or repositioned in the toilet. The urine analysis device is discreet. In addition, the urine analysis device can be removed to recharge a battery 94 or a rotating support 44 of the test assembly 24.
[0060] In the example illustrated in Figure 2, the housing 22 is arranged on the wall 16a of the toilet. The housing is positioned by a fixing element 66. The fixing element 66 comprises a suction cup 88 intended to cooperate with the wall 16a of the toilet and magnets 70. The magnets are intended to cooperate with magnets 23 (or pieces of ferromagnetic material) arranged inside the housing. This configuration makes it easy to remove or reposition the housing in the toilet.
[0061] The attachment element 66 may also include a ball joint. The ball joint allows the housing 22 to be oriented to increase the likelihood of contacting urine being received in the toilet bowl 16.
[0062] Alternatively, the fixing element 66 may be a hook mounted on a rim 16b of the toilet bowl.
[0063] General characteristics of the case
[0064] The housing 22 has an external shape of a circular pebble. In other words, the housing has a flattened spheroid shape. An axis A is the median axis of the housing. The housing has a front face 25 and a rear face 26, substantially normal to the axis A. Thus, urine can be collected directly from the faces 25, 26 of the housing. The housing serves as a urine collector.
[0065] The front face 25 is oriented towards the inside of the bowl 16. The front face 25 is then intended to receive urine when the user urinates while sitting on the toilet. The rear face 26 is oriented facing the inner wall 16a of the bowl 16. The front face 25 and the rear face 26 are connected by curved edges 27. Then, the outer surface of the housing 22, consisting of the front face 25, the rear face 26 and the curved edges, is defined by curved lines, forming a generally convex object. The housing is devoid of edges. Urine can run over the entire outer surface of the housing without detaching from the housing or forming air bubbles, which could compromise a urine analysis.
[0066] Preferably, the housing 22 has a diameter D22, measured in the direction normal to the axis A, of between 50 mm and 150 mm, preferably close to 100 mm. The housing 22 also has a thickness E, measured in the direction of the axis A, of between 15 mm and 50 mm, preferably close to 30 mm. Thus, the housing is sufficiently compact to be entirely received in the toilet bowl. The urine analysis device is discreet. In addition, the housing is sufficiently extended to systematically come into contact with urine being received in the bowl. The user can then urinate in the toilet without worrying about the urine analysis device.
[0067] The outer surface of the housing is smooth. Thus, the urine jet coming into contact with the housing clings to and spreads over the outer surfaces of the housing. Preferably, the housing is made of a hydrophilic material. For example, the housing may be made of one of: a ceramic, a polyamide (PA), a silicone or a hydrophilic polymer. The outer surface of the housing may also be treated with a hydrophilic surface treatment, for example acuWet® from the company Aculon, a hydrophilic polymer, or Pebax® from Arkema.
[0068] As more visible in Figure 4, according to a particular embodiment, the housing 22 is formed as an assembly of two half-shells and is here constituted by a front shell 28 and a rear shell 30. The front shell and the rear shell form a joint 31 of the housing, in a plane normal to the axis A. The assembly of the urine analysis device is facilitated when the housing is constituted by the front shell and the rear shell.
[0069] The front shell 28 and the rear shell 30 are assembled to maintain the outer surface of the housing defined by curved lines. Then, the joint 31 between the front shell and the rear shell allows urine to flow between the front face and the rear face. The impact of the joint on the flow of urine on the housing is minimized.
[0070] The front shell 28 and the rear shell 30 can be assembled by screwing, gluing, clipping, by magnetization, or ultrasonic welding. Of course, other fixing means can be implemented to assemble the front shell and the rear shell.
[0071] For example, the front shell 28 and the rear shell 30 are assembled by screwing. Then, an internal portion of the front shell has a thread. The thread of the front shell is intended to cooperate with a tapping of the rear shell. The housing can thus easily be disassembled to access the test assembly 24 inside the housing.
[0072] A seal may be present at the joint 31 between the shell front and rear shell. Thus, the housing is waterproof. The interior of the housing is impervious to urine, water from the water tank 14 or the bowl 16, and any other type of contaminant. Only collection and drainage holes connect the exterior and interior of the housing, as described in more detail later.
[0073] Other functions supported by the device
[0074] In the example illustrated in Figure 5, a removable cover 90 is arranged on the rear shell. The removable cover makes it easier to access the test assembly 24, in particular to a rotating support 44 of the test assembly. The removable cover 90 makes it possible in particular to reload the rotating support of the test assembly.
[0075] The removable cover 90 is here fixed to the rear shell 30 by clipping, screwing or by a bayonet mechanism. Of course, other fixing means can be implemented to fix the removable cover 90 to the rear shell. Alternatively, in an example not illustrated, the removable cover 90 could be fixed to the front shell 28.
[0076] The removable cover 90 is arranged in a sealed manner. For example, a joint between the removable cover 90 and the rear shell 30 may comprise a seal. Thus, the interior of the housing 22 remains impermeable to urine, to water coming from the tank water 14 or bowl 16, and any other type of contaminant.
[0077] The housing 22 has a collection orifice 32. The collection orifice 32 can receive urine flowing by gravity onto the outer surface of the housing. Urine is collected directly from the faces 25, 26 of the housing.
[0078] The collection orifice 32 is located on a lower end 36 of the housing 22. The lower end 36 is oriented towards the bottom of the bowl 16 when the housing 22 is positioned in the bowl 16 of the toilet. This position corresponds to a normal position of use. This position allows collection of urine flowing by gravity over the majority of the exterior surface of the housing.
[0079] In this case, a distance D separating the collection orifice 32 from a lower edge 22a of the housing is less than 40 mm, preferably less than 20 mm. According to a particular embodiment, the collection orifice 32 is arranged a few millimeters above the lower edge of the housing. Alternatively, the collection orifice may be on the lower edge 22a.
[0080] The collection orifice 32 is a circular opening, preferably with a diameter of between 0.3 mm and 2 mm. The diameter of the collection orifice may be chosen to maximize the volume of urine collected from the outer surface of the housing.
[0081] The housing has a drain orifice 34. The drain orifice 34 allows the urine analysis device 12 to be purged of excess urine.
[0082] The drain orifice 34 may be separate from the collection orifice 32. Then, the drain orifice is also located on the lower end of the housing, in the vicinity of the collection orifice. The drain orifice is also a circular opening. The drain orifice has a diameter of between 0.3 mm and 2 mm. In the normal position of use, the drain orifice is located below the collection orifice
[0083] Alternatively, as illustrated in Figure 5, the drain orifice 34 may be the same as the collection orifice 32. A single orifice makes it possible to limit the number of openings towards the interior of the housing. Then, the risk of introducing contaminants or elements likely to obstruct the test assembly is reduced.
[0084] As seen in Figure 6, the collection orifice 32 and the drain orifice 34 may be topped by a metal mesh filter 92. The filter covers the orifices 32, 34. The mesh filter is, for example, oblong in shape covering the orifices 32, 34. The average mesh opening of the filter is, for example, 20 microns. The filter prevents the introduction of contaminants or elements likely to obstruct the test assembly 24, and filters the urine received in the collection orifice. Furthermore, the filter could be cleaned using an air flow generated by an air pump.
[0085] In the examples illustrated in Figures 2 to 7, the collection port and the drain port are located on the rear face of the housing. Then, the collection port and the drain port drain holes face the inner wall 16a of the bowl when the urine analysis device is positioned in the toilet. This position allows the collection hole and the drain hole to be hidden by the front face of the housing. Also, this position helps prevent the introduction of contaminants or elements that could clog the test set.
[0086] The collection orifice and the drainage orifice are located in a recess 37. The recess 37 comprises two lateral grooves 39 extending from the joint 31 of the housing towards a central part 43 of the recess 37 comprising the orifices 32, 34. The depth of the lateral grooves 39, i.e. the distance from the rear face 26 towards the inside of the housing in the direction of the axis A, increases from the joint to the central part 43. Thus, the recess 37 forms a urine supply from the front face 25 to the collection orifice. Advantageously, the recess makes it possible to collect urine running down the front face and convey it towards the collection orifice. Thus, the volume of urine reaching the collection port from the front of the box is sufficient for the purposes of the analysis.
[0087] A border 40 delimiting the recess is rounded. In other words, the border is defined by curved surfaces. The border is edgeless. Urine in contact with the rear face can flow toward the collection orifice without detaching from the housing or forming air bubbles. Thus, the volume of urine reaching the collection orifice from the rear face of the housing is increased.
[0088] The housing 22 is not limited to the embodiments described above with regard to the figures, but is, on the contrary, capable of numerous variants accessible to those skilled in the art.
[0089] The housing may in particular take any geometric shape defined by curved lines. The housing may in particular have a diamond shape or an inverted drop shape. Then, the housing has a point on the lower part in order to guide the urine towards the collection orifice.
[0090] The collection port and the drain port may be on the front face of the housing. Thus, urine flowing down the front face reaches the collection port more directly.
[0091] The collection orifice and the drainage orifice may be located on a positive relief, in particular a projection, or a negative relief, in particular a gutter or a recess. Generally, the relief may be of any geometry allowing the urine flowing over the housing to be channeled and directed towards the collection orifice without detaching from the housing or forming air bubbles.
[0092] In an exemplary embodiment, the collection orifice 32 is arranged on the front face 25, while the drain orifice 34 is located on the rear face 26.
[0093] Test assembly, injector. analysis system
[0094] Subsequently, a test set 24 using colorimetric strips is described in more detail. The colorimetric strips are also referred to herein as “test strips” 56.
[0095] The test set 24 is controlled by an electronic control unit 45. The electronic control unit 45 makes it possible to control the components of the test set 24 to carry out a urine analysis using the test strips 56 and obtain one or more analysis results.
[0096] As seen in Figure 14, the test strips 56 are of the lateral or vertical flow immunoassay type. Then, the test strips 56 comprise a sampling pad 100 and an absorption pad 102. A nitrocellulose membrane 104 extends between the sampling pad 100 and the absorption pad 102. Then, when a urine sample is introduced onto the sampling pad 100, it migrates by capillarity to the absorption pad 102 by passing through a conjugate pad 106, one or more test lines 108, and a control line 110. The conjugate pad 106, the test line(s) 108 and the control line 110 contain reagents.
[0097] The conjugate pad 106 includes, among other things, detection antibodies sensitive to compounds contained in the urine. If the compounds are present when the urine sample passes through the conjugate pad 106, then the antibodies bind to the compounds to form markers. The markers migrate to a test line 108. The test line includes, among other things, test antibodies. The test antibodies bind to the markers and retain them on the test line 108. Then, a colored line is formed and the density of the line varies depending on the concentration of markers present. The remaining sample migrates to a control line 110. The control line includes control antibodies, making it possible to indicate that the sample has passed through the nitrocellulose membrane 104.
[0098] For example, the test strips 56 may be ELISA type strips. This type of test strip 56 allows detection of the pregnancy hormone hCG in urine. Then, the detection antibody may be “mouse monoclonal beta hCG”, the test antibody may be “goat polyclonal anti-mouse IgG” and the control antibody may be “rabbit polyclonal anti-mouse IgG”.
[0099] Alternatively, the test strips 56 may be conventional colorimetric strips. Then, each test strip comprises a pad containing one or more reagents sensitive to one or more compounds contained in the urine sample. For example, the compound(s) may be: LH hormone, HCG hormone, leukocytes / nitrites, urobilinogen / bilirubin, proteins, pH, specific gravity and / or glucose.
[0100] Each test strip 56 is generally rectangular. A width 156 of each test strip 56 may be between 0.5 mm and 3 mm, preferably about 1 mm. A length L56 of each test strip may be between 10 and 15 mm, preferably about 12 mm. Alternatively, each test strip may have any shape, for example square or circular. The shape and dimensions of the test strips make it possible to store a large number of test strips in the urine analysis device 12. Indeed, it appears possible to store up to 120 test strips, which corresponds to 4 months of analyses when a user performs one analysis per day.
[0101] The test assembly 24 utilizing the test strips specifically comprises one or more rotating supports 44, an injector 46, a urine delivery means 48 and an analysis system 50.
[0102] The test assembly 24 is arranged on a base 68. The base makes it possible to position, or even fix, the injector 46, the rotary support(s) 44, the urine conveying means 48 and the analysis system 50 in the housing.
[0103] Rotating support
[0104] The test strips 56 are stored in the rotating support 44. Preferably, the rotating support 44 is of hollow cylindrical shape extending annularly around the median axis A of the housing 22, in practice the rotating support is generally symmetrical in revolution around the axis A. The rotating support 44 makes it possible to store a large number of test strips 56 while being sufficiently compact to be arranged inside the housing.
[0105] In its shape and function, the rotary support 44 is similar to a barrel.
[0106] In this case, an external diameter D44 of the rotary support 44 may be between 30 mm and 130 mm, preferably approximately 60 mm. A height H44 of the rotary support, measured in the direction of the axis A, may be between 12 mm and 40 mm, preferably approximately 14 mm. A ratio between the diameter D44 of the rotary support 44 and the diameter D22 of the housing 22 may be greater than or equal to 0.3, preferably greater than or equal to 0.5. This provides a solution of very good compactness with regard to the large number of test strips available.
[0107] Here, the test strips 56 are received in an outer wall 44a of the rotatable holder 44. As a result, the number of test strips 56 that can be stored by the rotatable holder is even greater.
[0108] Alternatively, in an example not shown in the figures, the test strips may be stored in an inner wall of the rotating holder. This arrangement prevents the user from touching the strips when handling the rotating holder. This configuration further allows flexibility in the positioning of the injector and the analysis system relative to the rotating holder.
[0109] According to another example not illustrated, the rotating support 44 could be a washer, with an axis coincident with the median axis A of the housing. The washer then extends radially, along a plane substantially normal to the median axis A of the housing. The test strips can then be stored on one face of the washer, normal to the axis A. This configuration makes it possible in particular to adapt the rotating support to different shapes of housing. Then, the rotating support can be implemented in various urine analyzers.
[0110] As illustrated, the outer wall 44a of the rotating support has a succession of grooves 52 delimited by walls 78. The walls form housings 54 for the test strips. The walls make it possible to isolate a housing 54 from neighboring housings in the circumferential direction. Then, the housings 54 can separate the test strips 56 to be used during successive analyses. The used test strips are separated from new test strips.
[0111] The grooves 52 extend here in the direction of the axis A, substantially over the entire height of the rotary support 44. Then, the rotary support can comprise between 40 and 150 housings, preferably between 60 and 120. Thus, a large number of test strips can be stored in the rotary support.
[0112] Alternatively, the grooves 52 could extend in the radial direction. This configuration appears advantageous for further increasing the number of housings of the rotary support 44, and for storing more test strips.
[0113] Each housing 54 can receive a single test strip 56. All the test strips in the housings can be of the same type. By same type, it is meant that they are sensitive to the same compounds contained in urine. The rotating support is then adapted for a specific analysis.
[0114] Alternatively, the test strip 56 received in the housing 54 may be of a different type than the test strip received in the neighboring housing. Thus, several types of analyses, requiring different types of test strips, may be performed from the same rotating support 44.
[0115] Alternatively, each housing 54 may contain a plurality of test strips of different types. Thus, several types of analyses may be carried out from the same housing.
[0116] The rotary support 44 comprises an opening 74. The opening allows the passage of a needle 96 of the injector 46 through the rotary support, in particular to carry out an evacuation of urine contained in the urine analysis device 12.
[0117] In the example of Figure 9, the opening 74 is a circular opening extending radially through the rotary support. Alternatively, the opening 74 may be a slot extending over the entire height H44 of the rotary support. Alternatively again, the opening 74 may be defined by an angular sector, as illustrated in Figure 11. The shape of the opening makes it easier to manufacture the rotary support, in particular during injection molding manufacturing.
[0118] In the example illustrated in Figure 9, the rotary support 44 is made of a single piece. As more visible in Figure 10, the grooves 52 are then arranged in groups of 3 in a plane tangential to the outer wall 44a of the rotary support. This arrangement limits the number of inserts necessary for the manufacture of the rotary support during manufacture by injection molding.
[0119] Alternatively, in the example illustrated in Figure 11, the rotary support 44 is formed by two parts. A first part 58, called the 'armature', takes the form of a hollow cylinder or ring extending around the axis A, being coaxial with it. An annular rib 60, extending radially outwards, surrounds one end 58a of the first armature part 58. Then, the test strips 56 can be positioned on the first armature part 58. The test strips can then be connected to form a ribbon 62. A second part 64 comprises a ring 95. The ring 95 is intended to cooperate with the end 58b of the first armature part 58, opposite the first end 58a in the direction of the axis A, to form the rotary support.
[0120] The ring 95 comprises a succession of projections 97 extending in the direction of the axis A, in the assembled position, up to the annular rib 60 of the first armature part 58. The projections 97 separate the test strips 56 from the ribbon 62. Then, the projections 97 form the walls of the housings 54 receiving the test strips. This configuration facilitates the handling and assembly of the test strips in the rotating support.
[0121] Each housing 54 is covered and closed by a seal 72. The seal makes it possible to hermetically isolate the test strips received in a housing from the external environment and from neighboring housings. Thus, before an analysis, the reagents of the test strips are protected from possible contamination. In addition, after an analysis, the seal 72 can contain urine introduced into the housing 54
[0122] As can be seen in particular in Figures 9 and 11, the cover 72 can take the form of a continuous film. The film is glued to the outer wall 44a of the rotary support to cover the housings 54. This configuration facilitates the installation of the cover 72 on the rotary support.
[0123] Such a construction allows for simple and automatable assembly, from relatively simple components. The cost of a rotating support equipped with test strips is thus advantageous.
[0124] Alternatively, each housing 54 may be covered by a separate cover 72. This configuration makes it possible to limit the risk of contamination of test strips received in two neighboring housings.
[0125] Alternatively, the test strips 56 may be individually encapsulated. This configuration appears particularly advantageous when the test strips are connected to form a ribbon 62. Indeed, the ribbon 62 can be assembled in the rotating support without requiring the addition of an additional seal 72. The assembly of the urine analysis device 12 is facilitated.
[0126] The seal 72 is here made of an inert material. For example, the seal may be made of silicone or acrylic. Preferably, the seal is of medical grade, to avoid contamination of the test strips with undesirable products contained in the seal. Then, the reagents of the test strips are kept intact before an analysis.
[0127] Furthermore, the seal 72 is transparent, a transparency rate preferably being greater than 99%. Then, a colorimetric analysis can be carried out on a test strip through the seal.
[0128] The rotary support 44 is assembled on the shaft of a motor 76 (figure 4) to be driven in rotation about the axis A. The rotary support can then be selectively positioned to align a test strip facing the injector 46 or facing the analysis system 50. Thus, the use of the rotary support makes it possible to have a simple mobile assembly with a single axis of rotation. In addition, this configuration reduces the constraints linked to the positioning and arrangement of the injector 46 and the analysis system 50 in the analysis device 12.
[0129] The motor 76 can drive the rotary support 44 in a clockwise or counterclockwise direction. The rotary support can then quickly reach the desired position, following the shortest path. This further reduces the constraints related to the positioning and arrangement of the injector 46 and the analysis system 50 in the analysis device 12.
[0130] The motor 76 is for example a stepper motor. Then, the stepper motor allows controlled indexing of the rotary support. Alternatively, the motor can be a direct current motor.
[0131] The angular position of the rotating support 44 can be controlled by detecting one or more markers on the rotating support. The marker(s) allow the position of the rotating support in the urine analysis device to be precisely controlled. The electronic control unit 45 is coupled to a sensor configured to detect the presence in a particular position of the marker(s).
[0132] The rotating support can be inserted into the urine analysis device randomly, and the positioning of the rotating support can advantageously be carried out automatically, after an initialization step consisting of a “blind” rotation until at least one of the above-mentioned markers is located.
[0133] A point marker may be provided on the rotating support, this point marker acting as a 'zero' angular reference point. From the knowledge of this reference angular position called 'zero'. Then the stepper motor control memorizes the number of steps taken in each direction allows the electronic control unit to continuously follow the current angular position of the rotating support. This process is carried out in an open loop, but a possible recalibration can be provided each time the 'zero' marker is in front of the sensor.
[0134] In one example, the marker(s) may for example be magnetic markers.
[0135] In another example, the marker(s) may for example be optical markers. The optical markers may be lines or barcodes on the rotating support. The optical markers are intended to cooperate with an optical sensor 99. Advantageously, the use of an optical sensor may also make it possible to identify the type of test strips in the rotating support. In addition, the same optical sensor 99 may perform the colorimetric analysis on the test strips. This configuration makes it possible to reduce the complexity and costs associated with the manufacture of the urine analysis device, by limiting the number of components used during its operation.
[0136] The rotating support 44 is mounted in the urine analysis device in a removable manner. Then, the rotating support can be removed from the housing. The rotating support can be replaced, in particular to refill the test set 24 with test strips or to change the type of test strips. Then, the urine analysis device is modular and versatile.
[0137] In the example of Figure 8, the rotary support 44 has a female splined sleeve 93 capable of being assembled on a toothed male pinion of the motor shaft 76. The rotary support can then be easily removed and inserted from the housing by translation along the axis A, without compromising the rotation of the rotary support.
[0138] As illustrated in Figure 5, the housing 22, comprising a removable cover 90, is particularly suitable for removing the rotary support 44 from the housing. Indeed, the rotary support is easily accessible. In addition, the removable cover makes it possible to protect the rest of the test assembly 24 when removing the rotary support.
[0139] Bonnet variant, double barrel variant
[0140] In one example, the removable cover 90 is arranged on the front face 25 of the housing. In another example, the removable cover 90 is arranged on the rear face 26 of the housing.
[0141] As illustrated in Figure 5, a groove 90a is provided on the external face of the removable cover. This groove 90a makes it possible to rotate the removable cover 90 by inserting a coin therein, for example. The depth of the groove can be from 1 mm to 1.5 mm. Its length is close to the diameter D44 and its width can be from 2 mm to 2.5 mm.
[0142] In the example illustrated in Figure 12, the test assembly 24 comprises two rotating supports as described above, namely a first rotating support 44 on the outside and a second 442 arranged inside the first. The two rotating supports 44 are coaxial along the axis A. Two rotating supports make it possible to store more test strips in the housing. Then, each rotating support 44, 442 has an opening 74 in the form of a slot. The slots also allow the needle 96 to pass through to access the housings 54 of one or other of the rotating supports 44, 442.
[0143] Each rotary support 44,442 is driven in angular position by its own motor, two motors then being arranged in coaxial configuration.
[0144] The injector 46 comprises an automated syringe 80, on which the needle 96 is oriented towards the housings of the rotating support(s). The injector 46 is intended to pierce the seal 72 and inject a urine sample onto a test strip.
[0145] In the example illustrated in Figure 13, the injector 46 is arranged outside the rotating holder. The automated syringe 80 extends radially in the direction of the axis A. Then, the needle 96 points towards the outer wall 44a of the rotating holder. Alternatively, for example when the test strips are stored in an inner wall of the rotating holder, the injector could be arranged radially inside the rotating holder.
[0146] The automated syringe 80 injects, through the needle 96, a controlled volume of urine onto a test strip, for example between 2.5 microliters and 3.5 microliters. Thus, the automated syringe 80 injects a sufficient volume of urine onto a test strip to perform a conclusive analysis without risking urine overflow from the housing.
[0147] The needle 96 has a lateral opening. The lateral opening allows the passage of the urine sample from the syringe to the housings. The lateral opening prevents obstruction of the tip of the needle during several successive piercings.
[0148] The injector 46 may comprise a first sensor 89. The first sensor is arranged upstream of the automated syringe 80. The first sensor then makes it possible to detect whether urine is received in the automated syringe. The injector may further comprise a second sensor 87. The second sensor 87 is arranged in the automated syringe 80, near the needle 96. Then, the second sensor can verify that the automated syringe contains urine to perform an injection. The sensor(s) 89, 87 can then control the injection of urine onto the test strip.
[0149] The automated syringe 80 is arranged on a linear motor 91. The linear motor allows the automated syringe to be moved radially. At rest, the automated syringe is moved away from the rotating support to allow rotation of the rotating support. In addition, the automated syringe can be brought closer to the rotating holder to reach a test strip. The automated syringe 80 can also pass through the opening 74 of the rotating holder, in particular to evacuate excess urine from the automated syringe.
[0150] Furthermore, in the example comprising two rotary supports 44, 442 the automated syringe 80 can be moved radially to reach a test strip from one or other of the rotary supports 44. An overtravel is therefore provided to reach the second rotary support 442.
[0151] Pump and pipes
[0152] The urine conveying means 48 comprises a collection channel 82, a purge channel 84 and a pump 86. The collection channel connects the collection port 32 to the injector 46, in particular to the automated syringe 80. Then, urine can reach the automated syringe from the collection port. The purge channel 84 connects the injector, in particular the automated syringe 80, to the drain port 34. The purge channel then allows the urine contained in the urine analysis device to be evacuated.
[0153] Here, the purge channel 84 is arranged radially internally to the rotating support. The automated syringe 80 accesses the purge channel 84 through the opening 74 of the or each rotating support. Then, the urine can be evacuated by injecting the automated syringe into the purge channel. The urine analysis device may be devoid of components particularly dedicated to the evacuation of urine. The complexity of the urine analysis device is reduced.
[0154] The automated syringe 80 is here inserted into the purge channel 84. Then, the connection between the automated syringe and the purge channel is sealed. The risk of leakage during passage of urine from the automated syringe to the purge channel is reduced.
[0155] Preferably, the purge channel 84 is hydrophobic, allowing better evacuation of urine. Then, the risk of contamination of the urine conveyed between two successive urine collections is reduced.
[0156] The pump 86 is arranged between a first portion 82a and a second portion 82b of the collection channel 82.
[0157] The pump 86 can draw urine from the collection orifice 32. The pump draws, for example, between 5 microliters and 1 mL, preferably approximately 20 microliters. In addition, the pump makes it possible to convey a sufficient volume of urine to the injector 46 to be able to carry out a conclusive analysis. A suction flow rate of the pump 86 is chosen according to the diameter of the collection orifice. Advantageously, the pump can draw urine from the collection orifice to the injector without forming air bubbles.
[0158] According to another phase, after urination and outside the flushing sequence, the pump 86 can also draw air from the collection port 32. The air then passes through the urine delivery means 48 and the automated syringe 80 to the drain port 34. Then, the pump allows urine or water contained in the urine analysis device to be expelled. Urine collected for analysis is then protected from possible contamination by toilet water or from a previous collection.
[0159] According to another phase or an alternative embodiment, it may be provided that the pump 86 can suck in water when activating the toilet flush to evacuate the urine contained in the urine analysis device.
[0160] The pump 86 may be of various possible types. The pump 86 may be a miniaturized peristaltic pump. The pump 86 may be a miniaturized pneumatic pump system as detailed below.
[0161] In the case where the pump 86 is a miniaturized pneumatic pump, this pneumatic system is configured to create a vacuum in order to suck the urine from the collection orifice 32, then a positive pressure to push the urine towards the injector 46 and the purge channel. In addition, this pneumatic system comprises an internal buffer space interposed between the first portion 82a and the second portion 82b of the collection channel 82, an intake valve (non-return valve) and a discharge valve (non-return valve).
[0162] When this pneumatic system creates a vacuum, this sucks fluid from the collection orifice 32 via the first portion 82a and the inlet valve; the sucked fluid can then be, depending on the case, urine and / or water and / or air.
[0163] The fluid thus sucked is stored in the internal buffer space of the pneumatic system. Then, this pneumatic system creates an overpressure, and this pushes fluid, from the internal buffer space, through the discharge valve and the second portion 82b, towards the injector 46.
[0164] Thanks to the non-return valves, the pneumatic system can be free of controlled valves, which reduces the complexity of the urine analysis device.
[0165] The pump of the pneumatic system may here be a rotary type pump, the direction of rotation respectively and selectively providing a vacuum or an overpressure. The pump of the pneumatic system may also be a piezoelectric type pump.
[0166] When urine is aspirated, the injector may be provided to be in the purge position to evacuate air until urine reaches the threshold of the needle.
[0167] The solution presented makes it possible to precisely control the volume conveyed into the urine analysis device.
[0168] Other functions supported by the device
[0169] In one embodiment, the test assembly 24 comprises a urine presence sensor 38. The urine presence sensor is arranged proximate the orifice of collection. The urine presence sensor then detects when urine is present near the collection opening.
[0170] Preferably, the urine presence sensor 38 is a temperature sensor, for example a thermistor. The temperature sensor makes it possible to distinguish between urine and water coming from the toilet. In addition, the temperature sensor can also be used to measure the temperature of the urine. The temperature of the urine makes it possible in particular to detect periods of fertility, by comparison with one or more reference curves. The use of a temperature sensor then makes it possible to reduce the number of components used by the test set to carry out an analysis. The complexity and costs associated with the manufacture of the urine analysis device are reduced.
[0171] Alternatively, the urine presence sensor 38 may be any type of liquid detector, for example a capacitive or resistive type sensor. Then, a temperature sensor is distinct from the urine presence sensor. The temperature sensor may be dedicated to measuring the temperature of the urine, in particular to detect a period of fertility.
[0172] The analysis system 50 performs the colorimetric analysis on the test strips. “Colorimetric analysis” means a measurement of absorbance or fluorescence under predetermined illumination, in transmission or in reflection. The analysis system can then determine one or more analysis results.
[0173] The analysis system 50 is here arranged radially outside the rotating support. Alternatively, for example when the test strips are stored on an internal face of the rotating support, the analysis system could be arranged radially inside the rotating support.
[0174] Alternatively, the analysis system 50 may be arranged on a linear motor. By means of this, the analysis system may move closer to a test strip to perform a more precise analysis. This configuration appears particularly advantageous when the urine analysis device comprises two rotating supports. Indeed, the analysis system may perform a conclusive analysis on a test strip stored in the radially internal rotating support 442.
[0175] The analysis system 50 may include one or more light-emitting diodes (LEDs). The LED(s) illuminate a test strip.
[0176] Preferably, the analysis system 50 comprises several LEDs of wavelength specific to the different reagents contained in different types of test strips. Thus, the urine analysis device can perform different analyses with precision.
[0177] Alternatively, the analysis system 50 may comprise a single LED. For example, the LED may be white. Then, the LED may cover the entire visible spectrum. This configuration helps reduce the complexity of the analysis system.
[0178] The analysis system 50 may also include a collimator. The collimator makes it possible to direct the illumination of the LED(s) towards the test strip.
[0179] The analysis system 50 also comprises the optical sensor 99. The optical sensor 99 is in particular of the photodiode, CCD (“Charged Coupled Device”) or CMOS (“Complementary Metal Oxide Semiconductor”) type. Then, the optical sensor can measure the absorbance or fluorescence of the reagent of the test strip, in particular by transmission or reflection, to establish the analysis result(s).
[0180] The optical sensor 99 can be topped with a filter. The filter makes it possible to increase the sensitivity of the optical sensor to specific wavelengths. The precision of an analysis is then very satisfactory.
[0181] Communication and system aspects
[0182] The urine analysis device comprises a communication module 41. The communication is wireless. The communication module 41 uses a local network, for example of the Bluetooth, Bluetooth Low-Energy (BLE) or Wi-Fi type. The local network makes it possible to preserve a battery 94 of the test set 24. Thus, the autonomy of the analysis device is increased.
[0183] Alternatively, the communication module 41 may operate a cellular telecommunications network. The cellular communication network may, for example, be GSM, 3G, 4G, 5G, 4G-LTE. The communication module 41 then has a longer range.
[0184] Alternatively, the communication module 41 may operate a gateway connected to the cellular telecommunications network. The gateway may in particular be a router, for example a Wi-Fi router connected to the cellular network, a hub, i.e. a device connected directly to the cellular network, or the user's smartphone. Then, the urine analysis device may be connected to the cellular network without compromising the autonomy of the battery 94.
[0185] The communication module 41 makes it possible to trigger an analysis, via a remote command.
[0186] Preferably, the user can launch an analysis directly from a smartphone 61. The user has control over the urine analysis device, and can choose when he wishes to carry out an analysis, as well as the type of analysis he wishes to carry out. In addition, the user can be identified by the smartphone. The analysis carried out can be adapted to the identified user, and the results sent to enrich the history of this identified user.
[0187] Alternatively, the analysis is launched by communication with a remote device 42 near the toilets.
[0188] The remote device has a button 55. The user can then press the button to start an analysis. The user has control over the analysis device urine, and can choose when he wants to perform an analysis.
[0189] The button 55 may be provided with a biometric sensor 57. The button may then identify the user pressing the button. Then, an analysis relevant to the identified user may be performed by the urine analysis device. Furthermore, the analysis performed may be chosen based on the identified user, and the results sent to enrich the history of this identified user.
[0190] The remote device 42 also comprises a display 59. For example, the display may consist of one or more colored light-emitting diodes (LEDs). The display may also comprise a screen. The display makes it possible to inform the user. For example, the user may be informed that a button press has been perceived, and / or that the user has been identified and / or that an analysis will be carried out.
[0191] Alternatively, the remote device 42 may be a connected bracelet associated with the user. In this case, the user may be automatically detected when he is near the toilet. The user may also be identified by the connected bracelet. Thus, an analysis may be launched automatically, without action by the user. Note that the connected bracelet may be in the form of a connected watch.
[0192] The communication module 41 also makes it possible to communicate the analysis result(s). The analysis result(s) may be one or more magnitude(s) revealing one of: a fertile period, pregnancy, urinary tract infections, liver problems, kidney failure, uric lithiasis, dehydration, heart disease and / or diabetes.
[0193] The communication module 41 can send the analysis result(s) directly to the display 59 or to the smartphone 61. The communication module can then be without a connection to the cellular telecommunications network. The analysis result(s) can be interpreted locally by the electronic control unit 45, or by the smartphone application. Thus, the operating costs of the urine analysis device are reduced.
[0194] Alternatively, the communication module 41 can send the result(s) to a remote server 98. The remote server can interpret the analysis result(s). The use of a server makes it possible to reduce the computing capacity required locally for the interpretation of the analysis result(s).
[0195] The remote server 98 may also be provided with a storage capacity. Then, the remote server may store the result(s) of a plurality of successive analyses, for one (or each) user.
[0196] The user can view and use one or more analysis results, received directly from the analysis device or the server. For example, the user can view and use the results from the smartphone application. Alterna Typically, the user can access a website from a computer, to access this result data.
[0197] Process aspects
[0198] Subsequently, two methods for carrying out an analysis using the urine analysis device described above are described in more detail, with reference to FIG. 16 and FIG. 17. The methods are carried out by the electronic control unit 45. As illustrated in FIG. 15, the electronic control unit 45 receives information from the sensors 38, 99 and controls the motors 76, 91 as well as the pump 86.
[0199] The first method, illustrated in Figure 16, consists of launching an analysis following a user request.
[0200] Step E0 consists of maintaining the urine analysis device in a purge position. The opening 74 of the rotating support is aligned with the automated syringe 80 of the injector 46. The automated syringe passes through the opening of the rotating support. The automated syringe is inserted into the purge channel. Thus, urine or water received from the toilet in the collection channel 82 can reach the drain port 34.
[0201] In step E1, the urine analysis device receives the urine analysis request. The analysis request may come from the user pressing the button 55. The analysis request may also be ordered from the smartphone 61. The analysis request may also be carried out automatically, when the user is near the toilet. The display 59 may indicate to the user that their press has been received. The display may also indicate whether a user has been recognized when the button was pressed.
[0202] In step E2, the urine analysis device waits to detect urine near the collection port. The housing may further be equipped with LEDs to alert a user that the urine analysis device is waiting to detect urine.
[0203] If no urine stream is received within a given time, then the urine analysis device returns to step E0.
[0204] If, on the contrary, a jet of urine is detected, step E3 consists of activating the pump 86 to convey the urine from the collection orifice to the automated syringe 80. Step E3 stops when sufficient urine is detected in the internal buffer space or in the automated syringe to carry out an analysis.
[0205] Step E4 comprises positioning the urine analysis device in a pre-injection position. The pre-injection position prepares the urine analysis device for an injection of urine onto a test strip. The automated syringe 80 is retracted from the purge channel and the opening 74 of the rotatable holder, or it was already in a retracted position. The rotatable holder is rotated so that a housing of the rotatable holder faces the automated syringe.
[0206] It should be noted that steps E3 and E4 can be carried out simultaneously.
[0207] Step E5 then consists of positioning the urine analysis device in an injection position. The automated syringe 80 is translated by the action of the motor 91, to pierce the seal 72. The automated syringe injects urine onto a test strip. The injected urine can then react with the reagents of the test strip. After the actual injection, the needle can be retracted.
[0208] Step E6 consists of positioning the urine analysis device in the analysis position. It is first checked that the automated syringe is retracted from the housing. The automated syringe returns to the pre-injection position. The rotating support rotates to position the test strip having received the urine in step E4 facing the analysis system.
[0209] Step E7 consists of establishing the analysis result(s). The analysis system 50 performs a colorimetric analysis on the test strip. The urine analysis device deduces the analysis result(s) therefrom. The analysis performed depends on the type of test strip. The analysis performed may also depend on a user choice. The analysis performed may also be chosen based on the identified user.
[0210] Step E8 corresponds to the transmission of the result(s). The result(s) may be transmitted directly to the user. The result(s) may also be sent to the server 98. The user may, for example, view and use the result(s) on the smartphone application 61, or on a website. The result(s) may also be sent to a healthcare professional.
[0211] Step E9 consists of purging the urine analysis device. The pump 86 is activated to push air into the conveying means 48. Then, the urine is expelled from the urine analysis device via the purge channel and through the drain port 34. The urine analysis device then returns to the purge position of step E0.
[0212] It should be noted that steps E4 to E7 can be repeated several times. Thus, several test strips receive urine and are analyzed. Then, several analyses can be carried out from a single urine aspiration in step E3.
[0213] Alternatively, in the example illustrated in Figure 17, the method is initiated when urine is detected on the box.
[0214] Step E0 consists of maintaining the urine analysis device in the purge position, as described above.
[0215] Step E101 consists of detecting the presence of urine near the collection orifice 32.
[0216] Then, step E102 consists of activating the pump 86 to draw the urine from the collection port 32 to the automated syringe 80. Step E3 stops when enough urine is detected in the automated syringe and / or in the internal buffer to carry out an analysis. The display 59 can indicate that an analysis is ready to be performed. Alternatively, the box, equipped with LEDs, can indicate that an analysis is ready to be performed.
[0217] In step E103, the urine analysis device waits to receive an analysis request from a user. The analysis request may come from the user pressing the button 55. The analysis request may also be ordered from the smartphone 61.
[0218] If the analysis request is not received within a given time, then the pump is activated to purge the urine analysis device of the collected urine (Step E9). The urine analysis device returns to the purge position of Step E0.
[0219] If, on the contrary, the analysis request is received, then an analysis is carried out. The urine analysis device then carries out steps E4 to E9 as described previously.
