Description

The present invention relates to a device for determining the urinary flow rate of a user.

By examining a person's urine, broad conclusions can be drawn about their physical well-being. In this way, not only indications of diseases of the kidney and urinary system, but also of metabolic diseases such as diabetes or liver diseases can be discovered.

The amount of urine released when the urinary bladder is emptied or the flow rate of the urinary stream also provides clues to possible diseases such as prostate enlargement, which leads to a narrowing of the urethra and thus affects the flow rate.

The biochemical composition of urine can be examined using self-tests in the person's usual environment, although this often involves a subjective and by no means expert evaluation of the test.

Examinations that relate to both the flow rate and the biochemical composition of urine are often more complex and are usually carried out in doctor's offices or hospitals. Since many of the affected people shy away from going to a specialist or consider it unnecessary due to symptoms that are not yet too bothersome, many illnesses remain undetected that could be treated more efficiently through early detection.

The WO 2019/231513 A1 describes a uroflowmeter and a method for processing the data generated by it. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber connected to the handle, and a sensor connected to the flow chamber that detects a parameter of the urine received in the flow chamber. The uroflowmeter can contain both reusable and disposable components. As a uroflowmeter, it can identify and record data corresponding to the flow rate over the measured duration of a void, but it can also timestamp the void and transmit the data to an external data collection center for additional analysis and inclusion in a comprehensive void report or void diary . The urine is first collected in the uroflowmeter, which must be emptied and cleaned after use. However, a biochemical examination of the urine is not provided.

In the DE 10 2014 008 760 A1 A single-use urinary flow measuring device is disclosed, which comprises a substantially funnel-shaped collecting container with a lower end having an outlet opening for receiving urine liquid whose maximum flow rate (Qmax) is to be measured, wherein at the outlet opening a flow measuring device for measuring the maximum flow rate (Qmax) is arranged. This device also does not allow analysis of the biochemical composition of urine.

Finally describes the EP 3 331 450 A1 a device for determining physiological data by analyzing human excrement in a toilet using at least one indicator and / or sensor and a method for determining physiological data by analyzing human excrement in a toilet by measuring urine and / or stool values. A measuring system is used for this purpose, in which an indicator or sensor can be brought into a measuring position by means of an arm in which there is sufficient contact with the urine or stool to be examined, whereby the indicator or sensor is designed as an independent unit/ are, as well as a corresponding method in which a number of previously determined values are measured and then further processed and, if necessary, forwarded. The disadvantage of this device is that it has to be attached to a toilet and cannot be used hand-held.

The previously known devices either do not carry out uroflowmetry and/or biochemical analysis of the urine or are too large and too complicated to operate and are not suitable for home use.

In an application that has not yet been published, a device for measuring urine flow and for determining the biochemical composition of a user's urine stream is disclosed, having a flow area surrounded by an edge area, which can be brought manually into a measuring position. The device further has at least two first sensors for contactless detection of the flow rate of the urine stream and means for contactless detection of the biochemical composition of the urine stream, the first sensors being arranged on or in the edge region and one arranged in the flow area of the device or in the direction of the flow area have a pointing detection field and wherein the first sensors are optical sensors and / or ultrasonic sensors. This The device is very cost-intensive and can lead to undesirable measurement errors if the user holds it unsteadily.

The invention is based on the object of providing a device for simple urological prevention, which can be manually brought into a measuring position by a user and with which a user's urine flow rate can be determined.

According to a further object of the invention, a biochemical analysis of the urine should also be possible.

The task is solved by the features of protection claim 1. Further expedient embodiments of the invention are the subject of the dependent claims.

The invention is solved by a device for measuring the urinary flow of a user, comprising a vessel for collecting urine, which can be manually brought into a measuring position by a user, the device having a handle and the vessel having a base and a wall laterally delimiting an interior space, and with at least one signal processing unit and at least one first sensor connected to the signal processing unit for detecting the weight of the urine received in the vessel.

Furthermore, the device has means for recording the duration of micturition and the signal processing unit evaluates the increase in weight during the duration of micturition and determines the urine flow rate per period of time.

The first sensor is preferably designed as a weighing cell.

To determine the biochemical composition of the urine stream, the device further has at least one means for releasably attaching a test strip in an interior of the vessel.

As is known, the test strip indicates its biochemical composition when it comes into contact with urine.

According to the invention, the device further has at least one optical sensor for contactless detection of the test strip, wherein the at least one optical sensor is arranged on the vessel or on the handle and has a detection field directed or arranged into the interior of the vessel or in the direction of the interior of the vessel .

For the purposes of the invention, “urinary flow measurement or measurement of the urinary foot rate” is understood to mean the recording of the flow rate of urine during the period of micturition. Advantageously, when detecting the flow rate of the urine stream, the flow rate in ml/s and/or a total volume in a unit of time and/or the course of the flow in a unit of time can be detected.

The device according to the invention makes it possible to carry out a determination of the biochemical composition of the urine stream essentially at the same time as the urine flow measurement if a test strip is arranged in the device.

The vessel is preferably open at the top and has an opening through which the user can urinate. The opening has a diameter of at least eight cm. The opening and the circumferential wall delimiting the interior are preferably essentially round, with round including shapes such as circular, oval or teardrop-shaped.

In particular, the preferably round design of the opening and the wall ensures a better entry of the urine stream into the interior of the vessel and simplified cleaning of the device, since the wall has no corners in which urine residue can remain.

The vessel is preferably made of urea-resistant plastic.

In an advantageous embodiment, the first sensor is designed as a weighing cell. This makes it possible to record the weight of the urine in the vessel. If the duration of micturition is recorded at the same time, conclusions can be drawn about the flow rate of the urine stream, i.e. the volume that flows through in a certain unit of time.

The time recording can take place via a time recording unit integrated into the device, which can, for example, begin time recording as soon as the first sensor registers the beginning of urine intake in the vessel. The time recording is ended as soon as the urine intake in the vessel is also stopped.

Advantageously, the device has a handle that is designed to be gripped by a user.

In particular, the handle is connected to the vessel via a connection area. Advantageously, the first sensor in the connection The area can be arranged and in this way the weight of the vessel can be determined with great precision.

The weight of the container is transmitted to the weighing cell arranged in the handle (9) in particular by means of a transmission element.

The transmission element is integrated into the container.

In an advantageous embodiment, the transmission element with the container is detachably coupled to the handle and the weighing cell. The handle can thereby be removed from the container.

The transmission element is preferably designed as a metallic bending strip.

Also preferred in the handle are the control unit, as well as a switch for switching the device on and off and optionally a second switch for starting and ending the detection by the sensors.

The optical sensor is designed in particular as a camera.

Alternatively, the optical sensor can be designed as a color sensor.

Because the test strip is arranged in the detection field of the optical sensor and is designed as a camera, the optical sensor is able to perceive the test strip and a color change in the test letter.

The test strips used are advantageously easy to replace, and commercially available urine test strips can be used, each of which has several individual color fields that change color upon contact with the substance to be tested.

The test strip can be used to detect the biochemical composition of the urine released. The presence of at least one parameter selected from erythrocytes, proteins, sugars, ketones, leukocytes, bilirubin and/or urobilinogen in the urine stream is preferably detectable.

For example, an increased concentration of erythrocytes in the urine can indicate a possible inflammation or infection of the urinary tract and/or prostate, and in rarer cases also tumors such as kidney or bladder cancer, or urinary stones. As a rule, an erythrocyte quantity of 100 cells/ml can be considered harmless.

An increased concentration of leukocytes can also indicate inflammation and/or infections of the bladder or kidneys.

When testing for the presence of proteins, the concentration of albumin is particularly important. An increase in albumin concentration can indicate kidney damage in diabetes mellitus or high blood pressure.

An increased concentration of sugar, especially glucose, in the urine can be an indication of increased blood sugar levels and/or diabetes mellitus. The concentration of glucose in the urine can also be increased during pregnancy or in some types of cancer.

The presence of ketones as breakdown products of fatty acids in the urine can occur, for example, with a high-fat diet or with intensive fasting, but can also be a sign of metabolic derailment in diabetics and/or pregnant women.

Elevated bilirubin and/or urobilinogen levels in the urine can, among other things, indicate liver disease. However, the cause can also be a blockage in the flow of bile caused by gallstones, inflammation or tumors.

In particular, erythrocytes can be detected from a quantity of 5 erythrocytes/ml urine and/or proteins from a quantity of 10 mg/dl urine and/or sugar from a quantity of 40 mg/dl urine.

It can also be provided that the pH value of the urine to be examined is determined. A changed pH value can occur, for example, in cases of diarrhea or diabetes.

The discoloration of the test strip is detected by the optical sensor and evaluated by an evaluation unit. The evaluation unit can be arranged internally in the device or can be external, with the data recorded by the device being transmitted to the evaluation unit.

The test strip is preferably arranged inclined with respect to a plane which is spanned by the opening of the vessel. As a result, it can advantageously be better detected by the optical sensor, which is arranged in the area of the opening of the vessel.

The optical sensor is preferably arranged on or in the handle of the device. Is preferred an inclination of the test strip of 30°-45° in relation to the plane spanned by the opening. This particularly preferably results in an alignment of the image surface of the test strip of 80° - 100° with respect to the optical axis of the optical sensor.

It can also be provided that the optical sensor is arranged on the wall of the vessel or on the handle, with its detection field always being in the interior of the vessel. It is conceivable that in such a case the optical sensor is arranged on the wall of the vessel opposite the test strip or in the area of the handle.

Visual abnormalities in the urine stream can also be registered, which are directly detected by the optical sensor, for example a noticeable red discoloration or cloudiness. This alone allows limited conclusions to be drawn about the biochemical composition of the urine.

The means for releasably attaching a test strip is preferably designed in such a way that it is possible to automatically detect whether a test strip is attached or not.

Alternatively or additionally, the means for non-contact detection of the biochemical composition of the urine stream can also be designed in such a way that it can detect whether a test strip is attached or not and/or which test strip is attached.

It can be provided that the device has a reservoir for unused test strips.

According to a preferred embodiment, at least one lighting device for illuminating the detection field of the optical sensor is arranged on or in an edge region of the vessel or on the handle. A diffuser is advantageously arranged between the lighting device and the detection field of the optical sensor.

The means for releasably attaching a test strip is designed in particular on the wall of the vessel in such a way that a test strip attached to the means is positioned in the interior of the vessel. Alternatively, the means for releasably attaching a test strip can be arranged at the opening of the vessel or at its upper edge.

The means for releasably attaching a test strip can be in the form of a clip and made of an elastic material such that a test strip can be clamped into the resilient and/or resilient clip.

The device preferably has an actuator for activating and/or deactivating the means for releasably attaching a test strip.

Activation of the means for releasably attaching a test strip in the sense of the invention is understood to mean that the means for releasably attaching a test strip is brought into a position in which it releases the test strip.

Deactivation of the means for releasably attaching a test strip in the sense of the invention is accordingly understood to mean that a test strip inserted into the means is clamped and thus fixed. Deactivation can take place, for example, via a pressure point.

Advantageously, the test strip can thereby be removed from the means for releasably attaching a test strip without a user having to touch the test strip. As soon as the determination of the various parameters of the urine has been completed, the urine can be poured out of the device. The emptied device can then, for example, be held upside down (with the opening facing downwards) over a trash can and the user can release the used test strip by activating the actuator without having to touch it.

The activation or deactivation can take place, for example, magnetically or mechanically.

In a preferred embodiment, the actuator is designed as a magnetic coil (electromagnet) arranged in a wall of the vessel. Advantageously, the wall is made so thin that a magnetic field induced by the magnetic coil can influence the pressure point of the means for releasably attaching a test strip, which is arranged on the inner wall of the vessel. Such a magnetic coil can be activated or deactivated, for example, using the handle of the device.

In the aforementioned variant of using an electromagnet, the test strip must have a ferromagnetic area in the area where it is intended to interact with the electromagnet of the container.

Alternatively, a ferromagnetic clamping element can also be arranged in the container, in which case the test strip is positioned so that it is between the container wall with the Electromagnet and the clamping element is located. If the electromagnet is actuated, the clamping element is moved towards the container wall with the electromagnet and clamps the test strip. It can be provided that the clamping element is moved against a spring force towards the wall of the container and is moved back by the spring force when the electromagnet is deactivated, as a result of which the test strip is no longer clamped. With this variant, a commercially available test strip can be used.

Alternatively, a permanent magnet can also be arranged in the wall of the container and in this case the test strip can be partially magnetic or have a ferromagnetic element or be connected to a magnet or ferromagnetic element.

In a further embodiment, the actuator is designed as a mechanical pressure element. The actuator can be designed, for example, as a push button leading through the wall of the vessel. Of course, the tightness of the device at the breakthrough point must be ensured. Advantageously, in this embodiment too, the test strip can be detached from the means for releasably attaching a test strip without the user having to touch the test strip or the inner wall of the vessel. The test strip can be easily removed from the outer wall of the device.

In a further embodiment, the means for releasably attaching a test strip can be arranged at the opening, preferably at the upper edge of the vessel, and designed in the manner of a clip. Preferably, the user can first let the test strip fall into the container by operating the clamp and later dispose of it, for example over a trash can, by simply turning the device over.

The container can have a guide groove for inserting the test strip. Which is arranged in the container wall from the edge area of the container towards the bottom and partially contains the test strip.

Furthermore, the device preferably has at least one fastening means for releasably fastening an inner container, wherein the inner container can be arranged in the vessel in such a way that it separates the interior of the vessel from the bottom and the wall of the vessel.

Advantageously, an additional inner container is arranged in the vessel in which the urine is collected, so that the urine does not come into contact with the vessel. After pouring out the urine, the inner container can also be removed and disposed of.

It is possible to dispose of the inner container with the urine in the toilet if the inner container is made of a thin material that is suitable for this purpose.

This can be, for example, a thin paper material that is impermeable to urine, at least for a short period of use. In this case, the inner container should be made of a material that does not clog the toilet.

Advantageously, in such a case, the vessel has not come into contact due to the use of the inner container and the device does not need to be subjected to any further cleaning.

The use of an inner container minimizes the possibility of the user coming into contact with the urine and therefore increases hygiene.

When using an actuator to attach the test strip, which acts through the wall of the vessel, it must be ensured that the actuator also acts through the wall of the inner container.

This is the case if the inner container is made of a thin-walled material.

If the actuator is designed, for example, as a magnetic coil arranged in the wall of the vessel, the inner container must be made so thin-walled that the magnetic force can also act through it. For example, the inner container can be a foil bag or a cardboard and/or paper container that is coated at least on the inside.

The inner container is of course designed to be impermeable to the urine to be collected in the inner container.

In a preferred embodiment, the device has an interface for transmitting the data recorded by the first optical sensors and by the means for contactless detection of the biochemical composition of the urine stream to an evaluation unit, preferably to a computer and/or a mobile phone and/or a tablet .

Such an interface can be, for example, a Bluetooth connection or a WiFi connection.

The recorded data is preferably processed by means of a processor arranged in the device and then transmitted to the evaluation unit. Evaluation and display of the results can be done via an app.

It can also be provided that the device has an integrated evaluation unit and a display device and that the recorded data is evaluated directly in the device and the results are displayed.

Advantageously, the device can have one or more signal lights that emit a signal when predetermined critical limit values are exceeded or fallen below.

It can also be provided that the user is informed in the event of a deviation of the recorded data from standard or normal values, for example supplemented by a note that a doctor's visit is necessary.

In a further embodiment, the device has a storage medium for storing the data recorded by the first sensor and by the optical sensor.

Furthermore, the device preferably has a receptacle for at least one battery or at least one rechargeable battery for power supply, which can be arranged in the wall of the vessel or in the handle, with an arrangement in the handle being regarded as the preferred arrangement.

The design of the device according to the invention provides an easy-to-use device for home use, which enables early detection of urological key figures during urine flow. By examining their own urine, users can discreetly and privately draw conclusions about their body's health and, if necessary, seek additional advice from a specialist if the results of the examination indicate an illness or other change in the body.

The inventive design of the means for releasably attaching a test strip makes it possible not to have to touch the test strip during and after use.

The device offers a simple health check for the early detection of, for example, prostate, kidney or bladder diseases. Especially in older patients, a prostate/kidney/bladder disease that is diagnosed too late can lead to significant functional disorders. The easy-to-perform self-test means that any abnormal findings or changes over time can be quickly identified and a specialist can be consulted. Functional abnormalities (changes in urine flow such as enlargement of the prostate or narrowing of the urethra) as well as the composition of the urine components are evaluated and recorded. These results are stored digitally and can be viewed by the user and evaluated by a doctor.

The longitudinal measurement is easily repeatable and makes it possible to detect changes that occur over time. A follow-up check is also possible for diseases that have already been diagnosed, such as blood sugar disease, bladder cancer, urinary tract infections, kidney and/or bladder diseases, gout (ketones as a metabolic product during fat loss), stones and/or cancer.

The device according to the invention enables a combination of digital urine flow measurement and biochemical urine analysis. The data evaluation preferably takes place on the mobile phone. The particularly simple health check can be repeated as required and preferably triggers a warning if there are any abnormal findings. The usually very subjective strip test evaluation is objectified by the device according to the invention because it can be evaluated and documented digitally.

After use, the device is advantageously particularly easy to clean by pouring out the urine and rinsing with water. The device can be used by several users, for example in a family.

The device is advantageously designed as a hand-held device / hand-held and can therefore be used anywhere. It is possible to use the device at home, take it with you on vacation or generally use it in any location, e.g. in the toilet of a rest stop, a hotel or restaurant or even outdoors.

For use at home, the device according to the invention can be positioned near the toilet or urinal before and after use, for example on the toilet paper holder or on a separate holder that can be positioned on the wall or on the floor for easy access .

Of course, it is also possible to use the device according to the invention in medical facilities, such as routine fever measurements, for routine examinations to carry out urine tests without putting excessive strain on staff.

1 shows a schematic side view of a device according to the invention in section. A vessel 1 is designed to collect urine and has an in 1 floor, not shown, an interior and a wall 1.2 that laterally delimits the interior. The vessel 1 also has a spout 1.3, which is designed such that urine in the vessel 1 can be poured out easily and in a targeted manner. The device also has a handle 9, which is connected to the vessel 1 via a connection area 9.1. A cover 9.a or housing is arranged on the handle 9, on which an optical sensor 6 is arranged in the exemplary embodiment shown here. The optical sensor 6 is designed as a camera and has a detection field 6.1, which is directed into the interior of the vessel 1. A test strip 5 is arranged in the detection field 6.1 on the inside of the wall 1.2 of the vessel 1. The test strip 5 can thus be detected by the optical sensor 6. For this purpose, the test strip 5 is located in an area of the wall 1.2 of the vessel 1, which is arranged opposite the handle 9. In the embodiment shown here, the test strip 5 is located below the spout 1.3 of the vessel 1.

In order to ensure an optimal detection field 6.1 of the optical sensor 6 which receives the test strip, the optical sensor 6 is arranged at a height H above the edge of the vessel 1. And inclined towards the test strip 5. The height H is preferably at least 0.5 cm 3 cm The camera/optical sensor 6 can also be arranged on the handle 9 in an adjustable inclination.

In 2 a schematic side view of an embodiment of a device according to the invention is shown. You can see the vessel 1 with the bottom 1.1 as well as the wall 1.2 and the spout 1.3. The vessel 1 is connected to the handle 9 via a connection area 9.1. As described above, a housing-like cover 9.a with an optical sensor 6 located thereon is arranged on the handle 9. The connection area 9.1 is coupled to a load cell (not shown) integrated into the handle 9.

The cover 9.a or housing shape is intended to accommodate the camera (optical sensor 6) and the lighting (LEDs, preferably flash LEDs).

This in 2 The vessel 1 shown is cranked in order to prevent the vessel 1 from tipping. In addition, this embodiment has a large volume with a low overall height. Pouring out through the spout 1.3 is also made easier. In particular, fewer urine residues remain in vessel 1.

3 shows a representation of a part of the device with a view of the handle 9 and the optical sensor 6 arranged on the handle 9 and with lighting devices 7, preferably LEDs, arranged on both sides of the sensor 6. The centrally arranged connection area 9.1 and the cover 9a above it can be seen. The optical sensor 6 is also arranged in the middle of the cover 9a.

In 4 , which shows part of the handle 9 from the side, it can be seen that the cover 9a and the optical sensor 6 arranged therein are designed to be slightly inclined in relation to the handle 9. In this way, the detection field of the optical sensor 6 is extended into the interior of the in 4 vessel, not shown.

5 shows the in 3 and 4 shown area of the handle 9 from above with a view of the housing-like cover 9a.

6 shows a schematic representation of a device according to the invention from above. The vessel 1 can be seen, with the viewer's gaze in 6 is directed directly into the interior of the vessel 1, with the wall 1.2. The floor plan of the vessel 1 is essentially oval. Below the spout 1.3 there is a drainage channel 1.4 in the wall 1.2, in which the test strip (in 6 not shown). The groove provides lateral guidance when inserting the test strip, not shown here. Also visible is the connection area 9.1 to the handle, which is arranged opposite the spout 1.3.

In 7 is a schematic side view in section with a view of the first sensor 3 shown. The first sensor 3 for detecting the weight of the container 1 and thus the urine contained therein is designed in the form of a weighing cell and is arranged inside the handle 9, which is connected to the wall 1.2 of the vessel 1 via the connection area 9.1.

The connection area 9.1 is in contact with the load cell (the first sensor 3). The spout 1.3 is formed on the side of the wall 1.2 opposite the handle 9. This could also be arranged 90° offset from the handle 9.

The first sensor 3 is designed as a load cell and is connected to the connection area 9.1. In this way, the first sensor 3 can detect the weight of the vessel 1 and in particular of the urine located in the vessel 1.

In particular, the changing weight of the container 1 during urination is recorded and thus how much urine it micturates per period of time. This value is the urine flow rate.

8th shows a detailed view of the wall 1.2 of the vessel 1 in the area of the means 4 for attaching a test strip 5 and the enlarged detail X. On the inner wall of the wall 1.2. A means 4 for releasably attaching a test strip 5 is arranged in the lower region of the vessel 1 near the bottom 1.1. Means 4 is in 8th also shown greatly enlarged and designed in the form of a ferromagnetic element. The means 4 can be placed in an activated or a deactivated state, releasing the test strip 5 in the deactivated state and holding it in the activated state. A change between activated and deactivated state is possible via an actuator 8, the actuator 8 being arranged in the wall 1.2 of the vessel 1 in the embodiment shown here. For this purpose, the actuator 8 is integrated into the wall 1.2, which is designed here as a magnetic coil/electromagnet.

The actuator 8 can be injected with the associated unmarked line and into the wall 1.2.

The magnetic coil has a ferrite or iron core of the magnetic coil and is not movable.

Because the actuator 8 is arranged in close proximity to the ferromagnetic means 4, a magnetic field built up by the actuator 8 is able to put the means 4 into the activated state.

The means 4 can be magnetized, for example a small iron plate, a clamp, a magnet or magnetic strip attached to the test strip or the like, and clamps the test strip in the direction of the electromagnet with a force F in the direction of the wall 1.2 of the container in the container 1.

In a further variant, the lower end of the test strip can also be provided with a magnetizable metal area, which in the activated state adheres to the inside of the container when the magnetic coil is switched on. If the solenoid is deactivated, the test strip is released.

A greatly enlarged view of the actuator 8 arranged in the wall 1.2 is also shown in 9 shown. It is arranged here at a short distance from the bottom 1.1 of the container 1.

In the 10 to 12b Further variants for attaching a metallic component to the lower end of the test strip 5 are shown, the metallic ferromagnetic component being attracted and fixed by the electromagnetic coil when the test strip 5 is inserted.

The metallic component is according to the 10 and 11 (top view) and 12a and 12b (side view) designed as a flat clamp 11 and has two slots 12 through which three partial areas (not designated) are formed and in which the test strip 5 is guided and clamped.

From the 12a and 12b It can be seen that the middle section has an increase 13. If you press this, the middle area is swiveled downwards, thereby opening clamp 11 (see 12b) and the test strip can be inserted and then the clamp 11 can be closed.

The small elevations 14 serve to fix the test strip.

According to the 13 to 15 The metallic ferromagnetic component consists of a wire component 15, which has recesses 16 for engaging and clamping/fixing the test strip 5 and is provided with wire windings 17 at one end.

13 shows the individual part representation of the wire component 15, 14 the illustration with the test strip inserted from below and 15 the illustration with the test strip 5 inserted from above. It's from the 14 and 15 can be seen how the test strip 5 engages in the recesses 16.

The clamp 11 or the wire component 15 are attached to the upper end of the test strip 5 and inserted into the vessel (not shown) with the upper end of the test strip 5 pointing downwards.

If the electromagnet arranged in the wall of the vessel is switched on, the ferromagnetic component in the form of terminal 11 or wire component 15 is magnetized and is attracted and fixed against the wall of the vessel in the area of the electromagnet by the electromagnetic attraction.

In 16 the vessel 1 is shown with the handle 3 attached to it, which has the camera and an LED for lighting on its one pointing towards the inside of the vessel. An actuator 8 in the form of an electromagnet is integrated into the wall 1.2 above the floor 1.1. The handle 9 is connected to the container 1 via the connection area 9.1. The lighting device 7 and the optical sensor 6 are integrated into the handle 9, pointing towards the inside of the container 1.

The inner container 20, which is inserted into the vessel 1, is also shown.

The inner container 20 also has a base 20.1, a wall 20.2 and a spout 20.3.

17 shows the device with the inner container 20 inserted into the vessel 1. This sits with its base 20.1 on the base 1.1 of the vessel 1 and its wall 20.2 is located near the wall 1.2 of the vessel 1.

The spout 20.3 of the inner container 20 engages in the spout 1.3 of the vessel 1 and centers the inner container 2 in the vessel 1.

The test strip 5 with a clamp 11 attached to it was inserted into the inner container 20. If the actuator 8 in the form of the permanent magnet is switched on, the clamping element 11 and thus the test strip 5 is applied to the wall 20.2 with a force F and with this to the wall 1.2 of the vessel 1 pressed and thereby the inner container 20 and the test strip 5 are fixed in position.

According to a variant not shown, the inner container 20 can also be provided with an integrated test strip on the inside. This means that a holder for a test strip is no longer required on the vessel 1. The inner container then preferably also has a spout and is aligned and fixed with this in the spout of the container. The test strip arranged on the side of the spout of the inner container is thereby reliably detected by the camera (optical sensor 6).

It is possible to fix the inner container 20 to the upper edge of the container 1 (not shown).

18 shows a variant in which the test strip 5 rests on the bottom 1.1 of the container 1. The test strip 5 was positioned on the floor in container 1 before micturition.

The bottom 1.1 has, for example, a recess 1.1a, into which a ferromagnetic element 4 engages, which is attached to the back of the test strip 5 and positions the test strip 5 on the bottom 1.1.

The test strip 5 can continue to lie in a groove 21 in the floor and can therefore also be fixed in position.

Alternatively, the test strip 5 can also be placed on a flat floor 1.1.

In order to hold the test strip 5 in the container when pouring out the urine, an actuator 8 in the form of an electromagnet is arranged in the base 1.1, through which the test strip is attracted. After the urine has been poured out, the camera/optical sensor 6 can record/evaluate the test strip. The detection area 6.1 of the camera 6 is aligned here towards the floor 1.1.

The handle 9 and the spout 1.3 are arranged here, for example, offset by 90° to one another.

The support surface for the test strip 5 should preferably be arranged essentially horizontally up to an angle β of a maximum of 45° if there is a risk that the color markers of the individual areas of the test strip could extend to a vertical arrangement at an inclination of greater than 45° , as this may falsify the test result. The horizontal arrangement is given in the aforementioned variant, the arrangement of the test strip 5 on the floor 1.1.

Another variant for arranging the test strip is in 19 shown.

Here the spout 1.3 is relatively flat and has a groove 21 or a drainage channel 1.4 for positioning the test strip 5. The angle β of the storage surface for the test strip 5 is preferably 10° to 45°.

In the direction of the interior of the container, a stop 23 is provided for the test strip, through which its position is fixed.

It is possible to position the test strip at the outlet 1.3 at the beginning and, after micturition, pour the urine out through the outlet 1.3 so that the test strip is wetted. It must be ensured that the test strip remains in its position.

This can be ensured, for example, by the test strip 5 being stuck in the groove 21 or the drainage channel 1.4. After completing the detection of the test strip 5 with the optical sensor 6 arranged in the handle 9, the test strip 5 can be pulled out of the groove 21/the drainage channel 1.4 by hand (if necessary using hand protection/gloves) or with tweezers, for example, and disposed of.

However, it is as in 19 shown as an example, it is also possible to provide an actuator 8 (eg electromagnet) in the area of the spout 1.3, which holds the test strip 5 in its position. In this case, the test strip 5 must have a ferromagnetic element (not shown) which interacts with the actuator 8. The actuator is arranged, for example, in a housing 1.3a on the outside of the spout 1.3.

The detection area 6.1 of the optical sensor 6 is directed in the direction of the spout.

In this variant, the weighing cell in the form of the first sensor 3 is also positioned in the handle 9, which is arranged opposite the outlet 1.3. A connection area 9.1 also leads from the container 1 to the handle 9. The handle 9 is angled upwards here in order to be able to grip it better. Such a design of the handle is also possible with the other variants.

According to 20 It is necessary to introduce a dovetail-like groove 21 into the wall 1.2 or the spout 1.3 of the container 1, which is shown here in cross section. The test strip 5 can be inserted into the groove 21 from above and preferably clamps in the groove 21 in such a way that it does not slip out when the container is emptied. If the container is placed upside down, the test strip should 5 fall out of the groove 21. Alternatively, it can also be provided to grip the test strip 5 using, for example, tweezers (not shown) or by hand (if necessary with a protective glove) and to pull it out of the groove 21 of the container.

In the 21 and 22 are variants in the unclamped state ( 20 ) and in the clamped state ( 21 ) of the test strip 5 shown in cross section through the test strip 5. The test strip 5 sits here in a U-shaped groove 21, for example in the spout 1.3 or the wall 1.2.

In addition to the groove 21, the actuator 8 (electromagnet) is integrated into the wall area 1.2 or into the spout 1.3 of the container. A ferromagnetic clamping element 22 with one end 22.1 is integrated into the wall 1.2, 1.3 of the container, which grips over the test strip 5 and with its other end 2.2 extends over the actuator 8 and according to 21 in the deactivated state forms a gap to the test tire 20 and to the wall 1.2. If the actuator 8 is activated, the second end 22.2 of the clamping element 22 is pressed against the container wall 1.2 with a force F due to the magnetic attraction and thereby also clamps the test strip 5 in the groove 21. If the actuator 8 is deactivated, the test strip can be released after reading with the optical sensor (not shown here) and the clamping of the test strip 5 is released by springing back the clamping element 22, after which the test strip 5 can fall out by turning/tilting the container.

In the 23 is shown in side view and in 24 A variant is shown in the plan view, in which a shelf 24 is attached to the outside of the container 1, on which the wetted test strip 5 can be placed for reading with the camera 6. A spout is not provided here on container 1.

The camera/optical sensor 6 is also arranged in the handle 9 here, but could also be integrated into the container wall or the shelf.

The shelf 24 is arranged here, for example, below the handle 9 and also has a groove 21 for fixing the position of the test strip 5.

The first sensor 3 for weight detection is integrated here into the bottom 1.1 of the container 1. A membrane 3.1 is attached above it, which transfers the weight of the collected urine to the sensor 3. A line (not shown) leads through the container wall 1.2 to the handle 9 for the power supply, which is integrated into the handle 9, and/or for data transmission.

25 shows a separate shelf 24 with a groove 21 for fixing the position of the test strip 5. The shelf 24 is here provided with a sensor 6 (camera) integrated in a housing 24.1, whereby a power supply (not shown) can also be integrated in the housing 24.1. The data recorded with the sensor 6 via its detection field 6.1 are also preferably transmitted to a terminal via Bluetooth, as is the weight of the urine collected in the container 1 recorded over time using the first sensor 3.

The test strip 5 and the inner container 20 (if present) are preferably disposed of in the trash.

According to a variant, not shown, the handle 9 (and if present the shelf 24 with the camera 6) has a switch for switching on the power supply to the device and for establishing a connection (preferably Bluetooth connection) to a mobile device. For example, there may be an LED for on/off.

For example, a blue flashing LED indicates that the Bluetooth connection is being established and the permanently lit LED indicates that the Bluetooth connection is established.

For example, a red flashing LED indicates that the battery is empty.

Furthermore, the device has a switch for activating and deactivating the actuator 8 in the form of the electromagnetic coil or the electromagnet, if this is provided. It is also possible to activate the actuator by switching on the device.

A switch, preferably a push-button switch, is also advantageously provided, which is actuated at the start and after urination is completed. It can also be provided that a switch is pressed during the entire urination process and then released. The weight is then preferably picked up as long as the button is pressed.

Furthermore, it is possible for the start and end to be detected by the optical sensor 6 and/or the load cell. Instead of a button, for example, a touch sensor can also be provided

The LED for displaying data recording can also be replaced by an RGB LED to display the status of the device using different colors and light or flashing patterns.

Indicator lights may also be provided which indicate that the device and/or the electromagnet is/are activated.

Another indicator light can indicate, for example, when the test strip has finally been read out using the optical sensor and/or when all data has been transmitted to the end device.

• Über einen Schalter wird die Vorrichtung eingeschaltet. Bei Beginn der Benutzung wird ein Startknopf gedrückt und beispielsweise gedrückt halten bis der Uriniervorgang beendet ist oder nochmals gedrückt.

The exemplary application of the solution according to the invention without an inner container is explained below:

• The device is switched on via a switch. When you start using it, a start button is pressed and, for example, held down until the urination process is finished or pressed again.

After completion, the container is poured out over the intended area, wetting the test strip previously positioned in the container. The container can now be put down while the test strip is taking effect. During the exposure time or after the test strip has been developed, the optical sensor (camera) records the test strip.

When the test strip has been read out, this is signaled on a control display on the handle or on the container or the tray and/or on the app of the end device. An acoustic signal can also be generated in addition to the optical signal.

The battery can be charged via an electrical connection or magnetic contact or via induction charging.

Once the data has been read out, the device can be switched off and the urine strip can be extracted by deactivating the electromagnet or manually removed and disposed of.

Finally, the device and, if available, the shelf are rinsed out.

The vessel can have a groove for better pouring of urine and for targeted wetting of the test strip during the pouring process. The groove shape advantageously serves to preposition the test strip.

The test strip can be attached, for example, to the wall, the floor or in the spout of the vessel.

As already described above, the sensor for weight detection is located, for example, as a load cell in the handle, but it is also possible to detect the weight of the urine via a sensor in the bottom of the vessel, for example via a load cell or a weighing module. A plastic membrane, for example, can then be positioned above the load cell or the weighing module.

In this case, the change in weight over time must also be recorded to determine a user's urinary flow rate.

Advantageously, even with an arrangement for weight detection in the floor, the electronic and electrical components for switching on and off, the evaluation unit, data transmission, etc. are located, for example, in a reinforced side wall of the vessel and/or in the handle.

If only the urine flow rate is to be determined, an optical sensor is not absolutely necessary.

However, it is advantageous if the biochemical data of the urine is also recorded using a test strip. This is of course possible if the test strip is wetted with urine, for example by immersing it, and is evaluated visually.

However, it is simpler and more elegant if the test strip is attached to the container and is wetted and evaluated using the camera, since in this case data can be recorded and evaluated over a longer period of time and a trend is thus displayed.

It may also be possible to dip the test strip into the urine and then place the test strip at a predetermined position and record it using the camera.

The deposit can take place, for example, in the area of the spout (before or after emptying the container), if the spout is as in 19 is executed. Alternatively, the test strip can also be positioned on the floor after the container has been emptied. Or be positioned on another shelf.

There is then no need to additionally hold the test strip on the container (clamp/electromagnet/magnet and the like).

After using the device, it can, for example, also be stored in a designated housing for storage/storage be fied, for example by means of at least one UV lamp (not shown) arranged in the housing.

The aforementioned variants can also be combined with one another in any way, for example both the actuator 8 for fixing the test strip and the sensor 3 for detecting the weight can be arranged in the base 1.1 and the camera 6 for detecting the test strip 5 together with other electronic components in the container wall or in a housing provided for this purpose on the container wall.

According to an embodiment variant (not shown), it can further be provided that the device has a reservoir for unused test strips.

The device can be used by several users, for example in a family.

The device is advantageously designed as a hand-held device / hand-held and can therefore be used anywhere.

It is possible to use the device at home, take it with you on vacation or generally use it in any location, e.g. in the toilet of a rest stop, a hotel or restaurant or even outdoors.

For use at home, the device according to the invention can be positioned near the toilet or urinal, for example on the toilet paper holder or on a separate holder that can be positioned on the wall or on the floor for easy access or, for example, in a Enclosure that can be attached or placed on the wall or otherwise easily accessible.

Of course, it is also possible to use the device according to the invention in medical facilities, for example for routine fever measurements and for routine urine examinations, without putting excessive strain on the staff.

The invention describes an extremely practical device for home urological care for everyone. Whether man, woman or child. The system, known as “Streamcheck24”, consists of a type of “selfistick” with a ring or ring-shaped element at the bottom. The user can urinate through there when urinating. At least 2 cameras are installed in the side wall of the ring, facing inwards, which measure the geometry of the (jet) and record the flow rate in ml/s. Furthermore, the entire beam is recorded over the period of the respective process in order to record the total amounts (volume) and the course. Very good urological insights can be gained from this. One of the two cameras or another camera detects the biochemical data of the urine. Specifically, these are, for example, blood, protein, egg white. The data is stored in an app on the mobile phone and displayed visually there. In the event of deviations from (normal), the user will be informed and advised that a doctor's visit is necessary.

The following data is recorded in particular: 1. Flow rate a) ml/s b) Total volume / t c) Flow curve/ t 2. Blood = Erys < 5/ul 3. Protein = 10mg/dl 4. Sugar = 40 mg/dl. A feature of the invention is that instead of contactless recording of the biochemical data, a replaceable urine strip is used. This is also recorded and evaluated contactlessly by a camera. The urine test allows conclusions to be drawn about the health of the person being examined and changes that occur over time as well as a follow-up check in the case of illnesses. These can be, for example: Blood sugar disease, bladder cancer, urinary tract infections, kidney and/or bladder diseases, gout (ketone metabolic product when breaking down fat!), follow-up checks for stones, cancer, the pH value - this is changed, among other things, with diarrhea, diabetes, red blood cells: inflammation, Infections, cancers, urinary stones, white blood cells: inflammation, infections.

The aim is to make urological care as easy as possible for people - without much effort. The invention can easily be used by anyone when going to the toilet. Simply turn it on, urinate through the ring and you're done.

Then simply rinse with water and the Streamcheck is ready for the next use. The ring-shaped shape and the preferably round cross-section ensure that urine drains easily and any urine that may still be adhered to can be washed off easily and safely.
