Description

The present invention relates to a device for Measurement of urine flow with a rotatable gel collecting tray for collecting and controlled discharge th urine and a measuring element for detecting the Deflection of the drip pan from a rest position during a micturition, and a method for operating it Contraption.

The measurement of urine flow and micturition volume serves the data acquisition for the scientific classification of Urinary disorders, particularly the bladder and the Prostate, and is rotationally dynamic, gravimetric, capacitive and inductive possible. A device of The generic type is known from DE 30 07 855. Here, the drip pan is made within one Housing freely swinging, urine-free sen, with a slight slope essentially horizontal arranged U-shaped measuring tube formed in the Inlet nozzle opens a funnel and its outlet is arranged outside the housing. The urine flows through the U-shaped measuring tube, in which there is only one Subset of urine is a full micturition, so that the measuring tube can be made very small. As however, the rotatable mounting of the Collection tray by means of a leaf spring to look at with a measuring element cooperates. This storage of the on The trough using a leaf spring makes the device on the one hand, very sensitive, on the other hand, is in front of everyone Examining an elaborate and complicated manual  Calibration of those interacting with the measuring element Leaf spring required to determine the zero point. Furthermore, this device must then vorgenom calibration to determine the zero point in horizontal position in a toilet bowl to allow an accurate measurement of urine flow lichen. Therefore, this must be quite complex structured and sensitive device by specialist staff be prepared and installed so that they are out finally in clinics and special urological Medical practices can be used. There is also the after the measurement process to remove residues required Liche cleaning of the device easily possible, as well like caring for the sensitive sensors that are connected via cables connected to an externally arranged evaluation unit is. This gives the determined values as a Paper tape recorder trained output unit, which can then be evaluated in a known manner.

Because of the increasing cost pressure especially in Health care becomes a patient with simple preventive care investigations such as the one described Measurement of urine flow with significant additional Costs charged. A measurement of the flow data through the Patients themselves would use the regularly required and avoid high-cost visits to the doctor because he should only see the doctor if the result is positive, otherwise regularly check your data yourself could. With the device described above is one such own measurement, however, is not possible, since this Device not in because of the disadvantages described private or public toilets can be installed can, where appropriate, such a self-measurement is carried out. Because of the delicate construction and the externally arranged evaluation and output unit,  especially because of the required manual Calibration of the zero point is this device from not to serve an untrained patient. It would also be after use in public toilets few measuring processes unusable or even destroyed because besides urine stone also cigarette butts or other dirt can deposit in the drip pan and thus the Calibration falsified, leading to incorrect measurement results leads. These wrong ones, out on the paper strip printed measurement results could cause the patient to mistakenly consult a doctor if the pa stripe printer in the wet room even a ver valuable, d. H. allows legible expression. Finally can also by the device for output and Cables leading to the evaluation unit are easily damaged, so the values recorded by the device are not can be recorded and output.

Against this background, it is therefore the task of the present ing invention, a simple, robust and essentially Lichen maintenance-free device for measuring urine flow with a rotatably mounted drip pan for collecting and controlled drainage of urine and a measuring element for detecting the deflection of the on Collection tray from a rest position during micturition To provide a manual mechanical Calibration of the zero point is not necessary.

According to a second aspect, it is a further task of the present invention, additional urine tests in Own measurement for prevention with regard to further illness to enable images.  

Finally, according to a third aspect, it is another Object of the present invention, the output of Avoid measuring values on paper strips.

The first aspect of the task is solved in that the Device two essentially against each other Overlying magnets with the same polarity has, of which the first magnet on the drip pan and the second magnet is fixed to the device, so that the drip pan by the magnetic forces at rest location is held, and that the measuring element the distance to Collecting pan captured. The measuring element is preferably arranged fixed to the device.

For the urodynamic investigations mentioned here is the exact volume measurement and in particular the exact one temporal representation of the volume flow necessary to to be able to deliver reliable measurement results. Because of the The intended application in public toilets is Measurement with a closed measuring vessel not possible, see above that expediently the flow measurement with determination of the liquid weight over time is chosen. The Weight of the liquid is here over the distance between the sump and measuring element determines which by a suitable measuring element is determined. By initiating the weight of urine in the drip pan increases that they are about the rotatable bearing axis or position point is deflected from the rest position in which it is held by the magnets. The distance between Collection pan and measuring element consequently changes and is detected by the measuring element, with particular The advantage is that the distance before the start of the measurement can be determined and calibrated to zero. This enables automatic calibration before each Measuring process, with which each measurement is exact and  reliable values can be delivered. This is especially when using the device for example in public toilets is advantageous because there urine stone and dirt in the course of time Collect the drip pan and increase its weight. This increased weight of the drip pan can now Start of each measurement automatically determined and to zero point calibrated. The process of being controlled Derivation of urine from the drip pan, especially the Catch pan itself, is preferably at a distance from Pivot or arranged to the axis of rotation.

The sump is another preferred Embodiment of the device elongated and in the transverse cut substantially funnel-shaped, and has a spout in the floor area and one baffle arranged at an edge. So that the front used in every normal toilet bowl by, for example, one next to the Toilet wall located on which it is attached is folded over the toilet bowl. Of the The baffle will then urinate into the Collection tray directed where the flow measurement in the described manner.

If the device is not in a normal toilet basin is used, but according to another before preferred embodiment in a conventional urinal, so becomes the baffle plate arranged at the edge of the drip pan advantageously arranged substantially obliquely and the upper edge, removed from the drip pan, rotates Lich stored, and the first magnet in the transition area arranged by baffle plate and drip pan. This can the device firmly attached to a usually next to the Urinal provided partition are attached so that  Damage due to frequent folding of the device to be avoided on the urinal. Furthermore, the oblique arrangement of the baffle plate a reliable The urine is drained off into the drip pan when micturated ensures what particularly with regard to an exact Measurement is desirable. The rotating storage on the upper end of the baffle gives a long lever travel to the drip pan by the magnets in the rest position is kept and stored. The when measuring the Urine flow occurring relatively small deflections the drip pan therefore generate in the rotating Storage of the baffle plate only low friction forces, as this Bearing is only slightly deflected. This further reduces the interference influences on the measurement and increases thus overall the accuracy of the measurement.

It should be noted at this point that the term "with same polarity "is to be understood here that the magnets are arranged in a repulsive position, d. H. each with same poles face each other, so north-north or south-south. Likewise at this point notice that the magnetic forces that hold the hold the bath in the rest position by any other Forces can be replaced, for example by a spring forces or the like, without the area of inven is left. Have been advantageous here however, magnetic forces have been proven to be the drip pan can be held contactless in the rest position. Although the magnets that generate the magnetic forces are arbitrary can be trained, it has proven to be advantageous proven to design the first magnet as a ring magnet are to be arranged in a side wall of the drip pan, and form the second magnet as a round magnet and in essentially on the center line of the ring magnet Distance to this fixture.  

This opens the drip pan, which is pivoted simple way without great effort by the magnetic forces held in the rest position, the ring magnet centrically align to the round magnet. The is further simplified Device if according to a preferred embodiment the second magnet on one end of a fixture Holding rod is arranged by the ring magnet passes through, and the drip pan at the other end of the Holding rod is rotatably mounted. This will in particular, the assembly of the device is simplified, since the drip pan only on the fixture arranged holding rod needs to be pushed and is held there by the magnetic forces, while at the same time the magnetic forces in the drip pan hold the rest position. However, this also includes maintenance the device much easier when the Vorrich device for measuring urine flow, for example in public toilets is used and there is an off exchange or replacement of the drip pan required becomes such.

The accuracy of the measurement is further increased if according to an advantageous development for measuring the Distance between the two magnets uses a Hall element which is an electrical corresponding to the distance Voltage change provides.

Although the measuring process can be started as desired, so it is an advantage if according to one particular preferred embodiment, a second measuring element for Detection of the beginning of micturition is provided, which is advantageously designed as a piezo film. This releases a tension when pressure is exerted on it, so that for example by hitting the first drops Micturition a pressure on the piezo film is triggered  and subsequently a voltage is generated, which is a particularly simple detection of the beginning of micturition enables light. At the same time is by hitting individual drops an impulse count as well as by the with the pressure level corresponding voltage level a pressure measurement is possible. The piezo film is therefore advantageously in the Collection tray or arranged on the baffle plate.

Although the drip pan before the start of each measurement process to compensate for accumulated dirt the zero point can be calibrated, it is however from Advantage, a protective grille over the cover plate and catcher to attach the tub. On the one hand, this makes it unnecessary Accumulation of dirt in the drip pan avoided on the other hand there are undesirable drum effects of urine avoided on the piezo film, which the measurement could falsify, because the protective grille the urine stream equalized and dampens.

In a further expedient embodiment, the Start of measurement by deflecting the tub or by changing the distance between the magnets themselves triggered. The position of the trough is preferably reduced of the, usually minimal, deflection as Zero point used for the measurement. This is with voltage-generating measuring elements such as the one mentioned above Hall element particularly advantageous.

The second aspect of the task is solved in that a third measuring element is provided, which as an optical Measuring element designed to detect a color state is.

For example, the color of the urine be determined, but also discoloration of discoloration  chopsticks. The latter is particularly advantageous with one optical color sensor with LED standard lighting possible Lich, so that a preferred embodiment of the Vorrich device provides such a third measuring element.

Although such color measuring sticks for measuring various urine values are available, directly in the Collecting pan or immersed in the urine located there However, it is advantageous to have a second one Collecting pan under the outlet of the first collecting pan to be arranged and to hold discoloration measuring sticks train and the third measuring element of this second Allocate drip pan. The optical color sensor with LED standard lighting is then not accessible from the outside and consequently protected from damage and pollution.

Safe processing of the measuring elements set values is advantageously possible if this amplified by a measuring amplifier and then are preferably fed to an evaluation unit which Measured values are collected and processed. When using the Device in public toilets is still from particular advantage if the device according to a preferred embodiment an output unit for Output of the processed values. So that the Patient after measuring urine flow have the determined values output and control them yourself whether a check-up visit to a doctor is required is.

It is particularly advantageous here if the processed ones Values from the output unit on a card-shaped Storage medium are output. This is essential easier to handle than the usual paper strips print out, so that the acceptance of the device for  Use in public toilets increased significantly becomes. The card-shaped storage medium can be completed the measurement easily and inconspicuously in a pocket be stuck, especially if it is in the usual check card format is designed so that when leaving the public toilet in the patient no signs of an Use can be determined and therefore also with this no feeling of shame about the measurement of the Urine flow arises.

Although the processed values advantageously on the card can be printed, for example using ink or thermal head, as they can then be evaluated immediately it may be more advantageous for some use cases that prepared values in one on the card-shaped Storage medium arranged chip to store. This can then, for example, via an appropriate reader be read into a computer, whereupon a any processing of the values is possible.

A particularly simple one, the acceptance of the device further increasing operation results if according to a particularly preferred embodiment of the device by inserting the card-shaped storage medium into the output unit is activated. It can be used for any Controls for the device are dispensed with, by simply inserting the card-shaped memory is activated during the actual Measuring process according to the preferred described above Embodiment by starting the micturition process itself is triggered, e.g. B. by the corresponding impulse Piezo film or the deflection of the tub. If the kar ten-shaped storage medium then after completion of Measuring process, for example, automatically from the output unit is spent again, becomes a special one  easy-to-use device provided, which can also be used by laypeople.

A particularly preferred method for operating the device described in detail above therefore provides for the following method steps:

• - Activate the device by inserting one card-shaped storage medium in the output unit
• - Start the measuring process by a pulse of Piezo film triggered by urine impact at the beginning of micturition or by deflecting the up catch pan,
• - Before or at the beginning of micturition a first measurement of the Rest position or deflection of the drip pan, e.g. B. Measure the distance between the drip pan and Measuring element for zero point calibration,
• - Detect the distance between the drip pan and Measuring element as an initial value for determining the Liquid weight during or at the end of the micturition
• - if necessary amplification of the measured values in the measuring amplifier,
• - Collect, process and save the recorded values in the evaluation unit,
• - Output of the processed values during or after Micturition end through the output unit on the kar th shaped storage medium.

In the advantageous use of an optical color sensor with LED standard lighting, the preferred method has the following additional step:

• - Capture the color change of a color changing rod-shaped measuring element by a third Measuring element.

Overall, this is a method for operating the Device provided which is user-friendly and therefore essential for acceptance the device, especially when used in contributes to public toilets where the device should preferably be used.

The invention will now be described below with reference to FIG the drawings explained in more detail. It shows:

Fig. 9 shows the functional diagram of Fig. 8 in the deflected state under weight.

In Fig. 1, a first embodiment of the device 1 for measuring the urine flow is shown in a side view, which is arranged above a urinal 3 and BEFE on a partition 5 arranged next to the urinal 3 BEFE Stigt. On the partition, an output unit 7 is also arranged, which is provided with a cover 9 to protect it from dirt and splash water. The device has an elongated, essentially funnel-shaped collecting trough 11 , which is arranged on the edge of an integrally molded baffle plate 13 . The baffle plate 13 is arranged obliquely with an inclination towards the collecting trough 11 and is rotatably supported at its upper end on a bearing 15 . A piezo film 17 is arranged on the baffle plate 13 and is covered with a protective grid 19 . The protective grille 19 it also extends over the drip pan 11 and is held by two holding rods 21 , one of which is arranged at the upper end near the bearing 15 and the other at the lower end near the drip pan 11 . The holding rods 21 are fastened to the partition 5 , as is the bearing 15. In the transition area between the baffle plate 13 and the collecting trough 11 , a first magnet 23 is arranged on the underside of the baffle plate 13 , which has the same polarity as an oppositely arranged second magnet 25 . the second magnet 25 is disposed substantially below the first magnet 23, and preferably of tubular construction as part of a Meßelemententrägers 27, which in turn is fixed to the partition wall 5 and has a first measuring element for measuring the distance between the magnets 23 and 25, as will be described in detail below. Finally, the collecting trough 11 also has an outlet 12 through which urine located in the collecting trough 11 can drain into the urinal 3 .

The device 1 is activated by inserting a kartenför-shaped storage element into the output unit 7 . The urine jet is then directed against the baffle plate 13 and hits the piezo film 17 there , whereby pressure is generated thereon, which in turn results in a voltage output of the piezo film. This voltage output is the signal at the start of the measuring process. The urine is passed from the baffle plate 13 due to its inclination into the collecting trough 11 , whereupon its weight increases and the bearing 15 is deflected around it from its rest position, in which it was held by the magnets 23 and 25 , respectively. The changing distance between the magnets 23 and 25 is detected by a measuring element, as will be described below, and used to determine the liquid weight. The urine in the collecting trough 11 then flows through the outlet 12 into the urinal 3.

FIG. 2 shows the front view of the device 1 according to FIG. 1, but without a urinal. As can be clearly seen here, the protective grille 19 is part of a cover which completely covers both the baffle plate 13 with the piezo film 17 arranged thereon and the collecting trough 11 . The cover or the protective grille 19 is firmly connected to the partition 5 by means of the holding rods 21 and has a target circle 26 in order to impart a sporty character to the use and thereby reduce the sense of shame. Like the protective grille 19 , the output unit 7 with its cover 9 and the measuring element carrier 27 are firmly connected to the partition 5 . The device 1 is thus compact. and robust and can be easily integrated into any existing toilet facility.

It should also be noted that the baffle plate 13 with the collecting trough 11 arranged thereon is only mounted on the bearing 15 fixedly connected to the partition 5 , as can be seen in FIG. 1, so that these can be exchanged easily and simply. In addition, due to the magnetic forces of the magnets 23 and 25, the suspension pan 11 is suspended in an essentially friction-free manner, which works very sensitively and essentially without friction, so that exact measurements are possible, not least because of the details above described automatic zero point calibration after activation of the device.

In Fig. 3, a functional diagram of the device is Darge, wherein an additional optical color sensor 39 with an LED standard lighting 41 is provided to determine the color change of a discoloration measuring stick 31 . A stream of urine is passed through the protective grid 19 onto the baffle plate 13 on which a piezo film 17 is arranged. The urine is passed from the baffle plate 13 into the collecting trough 11 , which increases its weight. The catch pan 11 , which is arranged on the bearing 15 so as to be rotatable by means of the baffle plate 13 , is thereby deflected somewhat around the bearing 15 , against the magnetic forces of the magnets 23 and 25 represented by the arrows 43. The change in the distance between the magnets 23 and 25 is caused by detects a Hall sensor 33 which conducts an electrical voltage change corresponding to the distance between the magnets 23 and 25 to a measuring amplifier 35 . Triggered by the impingement of the stream of urine to the piezoelectric film 17 voltage is tapped in a known manner in the vicinity of the bearing 15 of the piezoelectric film 17 and also supplied to the sense amplifier 35th This feeds the amplified measured values to a processor 37 , which processes and stores the measured values before they are sent to an output unit 7 after completion of the measuring process. The measured values determined by the optical color sensor 39 are also fed to the processor 37 . The optical color sensor 39 has an LED standard lighting 41 in order to detect the color change of a discoloration measuring stick 31 . This is immersed in a second collecting pan 28 or in the urine located there, which is led from the outlet 12 from the first collecting pan 11 into the second collecting pan 28 . From the second drip pan 28 , the urine then runs through the outlet 29 into the urinal, not shown.

After completion of the measurement process, the measurement data stored and processed in the processor 37 are fed to the output unit 7 and output by the latter to a card-shaped storage medium.

In FIG. 4 is a schematic side view of a functional diagram of a further embodiment of the device is illustrated. The drip pan 11 is rotatably mounted on a bearing 15 and has a Ringma gneten 23 . Fixed to the device, a round magnet 25 is arranged essentially on the center line of the ring magnet 23 at a distance from the latter. Furthermore, a measuring element 33 is provided, which is connected to connecting lines 67 and is arranged opposite the ring magnet 23 .

In FIG. 4, the collecting tray is ten 11 by the magnetic force of the magnets 23 and 25 in the rest position supported. In a weight loading of the collecting trough 11 through urine is such as shown in Fig. 5 deflected from the rest position. The force of gravity generated by the urine in the collecting pan 11 acts in the direction of arrow 65 and causes a rotation of the collecting pan 11 in the direction of arrow 63 around the bearing 15 . At the same time, the ring magnet 23 arranged in the side wall of the collecting trough 11 is moved downward, as a result of which its distance from the measuring element 33 increases. This change in distance is detected by the measuring element 33 and fed via the connecting lines 67 to a measuring amplifier (not shown) for further processing, as has been described in detail with reference to the first embodiment.

In Fig. 6, a third embodiment of the on device is shown in a schematic side view. In contrast to the second exemplary embodiment, in the third exemplary embodiment the collecting trough 11 is rotatably supported by means of a holding rod 45 . As can best be seen from FIG. 7, the holding rod 45 has at one end a thread 47 with which it is screwed into a carrier element 57 , and a round nut 25. At the other end of the holding rod 45 there is a groove 51 for Recording a protective screen, not shown, and a stop 49 are arranged. The drip pan 11 has in a side wall a passage 55 in which the ring magnet 23 is arranged, and on the opposite side a passage 53 which is smaller in diameter than the passage 55. As indicated by the dashed line with the arrow , The holding rod 45 with its stop 49 aufwei send end through the passage 45 into the collecting pan 11 is inserted until the stop 49 in the passage 53 , which has a projection 54 , comes to rest. This state is best seen in FIG. 6 men. As can also be seen clearly here protrudes beyond the end of the holding rod 45, on which the circular magnetic net angeord 25, from the collecting tray 11 out, when the up collecting tray 11 abuts with the arranged in the passage 53 protrusion 54 on the stop 49th Due to the resultant distance between the ring magnet 23 and the round magnet 25 and the magnetic forces 59 and 61 present between them, the collecting trough 11 is held securely and reliably on the holding rod 45 on the one hand, and on the other hand without contact in the rest position, as detailed below described. With the end having the thread 47 , the holding rod 45 is screwed into a carrier element 57 , in which the ring magnet 23 is arranged opposite a measuring element 33 . Furthermore, the carrier element 57 also has a groove 51 for receiving a protective grid, not shown. When the device is used in a urinal, for example, the carrier element 57 can be fastened to the partition wall usually provided next to the urinal. The connecting lines 67 pass on the values detected by the measuring element 33 to the measuring amplifier (not shown) for further processing as described above. The urine passed into the collecting trough 11 flows out of the passage 55 from the collecting trough 11 , at which point a second collecting trough can be arranged, as has been described in detail with reference to the first exemplary embodiment.

The operation of the third embodiment will now be described in detail with reference to FIGS. 8, 8a and 9, which represent a functional diagram of the third embodiment. The drip pan 11 is rotatably on one side on the holding rod 45 gela and abuts the stop 49 here. On the other hand, it is held in the rest position by the ring magnet 23 and the round magnet 25 . These are arranged at a distance from one another, with their respective south poles essentially lying opposite one another. The attractive force acting between the south pole of the round magnet 25 and the north pole of the ring magnet 23 generates a force component 59 in the direction of the round magnet 25 , which holds the collecting trough 11 in abutment against the stop 49 , and a force component 61 , which relates to the ring magnet 23 the round magnet 25 "in suspension" or holds in the rest position. This is also shown in Fig. 8a, which shows a side view of the func onsschemas of Fig. 8. The magnetic forces "centering" the ring magnet 23 with respect to the round magnet 25 are represented by the arrows 61 .

When urine gets into the collecting trough 11 , a weight force acting in the direction of arrow 65 is generated, as shown in FIG. 9, which deflects the collecting trough 11 in the direction of arrow 63 . The stop 49 on the holding rod 45 acts as a rotary bearing for the catch pan 11. This deflection of the catch pan 11 around the stop 49 increases the distance between the ring magnet 23 arranged on the catch pan 11 and the measuring element 33. This distance is the measured variable which is detected by the measuring element 33 and passed on via the connecting lines 67 . When the urine has run out of the passage 55 out of the collecting trough 11 , this returns to the rest position as a result of the magnetic force 61 between the ring magnet 23 and the round magnet 25 .

As can be seen from the above detailed description of preferred embodiments of the device, it is very simple and compact, but at the same time robustly constructed, so that it is particularly suitable for use in public toilets in conjunction with its high user friendliness and exact determination of the desired values is. This is further supported by the fact that there are no exposed lines that are damaged and could impair the function of the device, as well as by the fact that the contactless arrangement of the sump 11 by means of the magnets 23 and 25 is a watertight closure of the Hall element 33 is possible.
