Description

The present invention relates to a portable combined urine flow meter that can be easily used outside a hospital such as a home and can measure urine flow rate and urinary salt concentration.

In an aging society, the importance of treating and preventing various diseases is emphasized. As an example of disorders associated with aging, for example, an increasing number of people have disorders such as urinary disorders and bladder dysfunction caused by prostatic hypertrophy in men, and in diagnosing and treating these, the flow rate of urine and It is important to measure the quantity. In addition, a large amount of salt intake affects high blood pressure, heart disease, renal disorders, gastric cancer, nocturia, etc. Most of the salt intake is excreted in urine, so the amount of salt in urine is measured. It is also considered important to estimate the salt intake by doing so.

As a urine flow meter for measuring the urine flow rate, conventionally, for example, a stationary urine flow meter in which a urine flow meter is installed in a toilet bowl and a change in water level in the toilet bowl is checked is used. Further, a method of storing urine in a container and examining a change in the weight of urine by using, for example, a load cell, and a urine flow meter for measuring urine flow rate characteristics without storing urine have been proposed (for example, Patent Document 1). 2, 3,).

On the other hand, as a method for measuring the amount of salt in urine, for example, 24-hour urine, for example, a plastic container or Urinemate P (urinemate is a registered trademark: manufactured by Sumitomo Bakelite Co., Ltd.) that proportionally collects 1/50 of urine for each urination The amount of urine is measured by collecting urine in a special container such as the one described above and measuring the Na (sodium) ion concentration in urine with an expensive analytical instrument or by requesting an analytical institution to analyze it. One method is to estimate the daily salinity based on the values of the urine volume and the urinary salt concentration. In addition, by analyzing the amount of creatinine and the amount of sodium from spot urine and using the ratio of the amount of creatinine excretion and the amount of sodium excretion per day estimated from the data of age, height and weight, A method of estimating the amount of salt excretion, or a method of estimating nocturnal urine in a 1-liter cup, measuring the amount of salt in the cup, and estimating the amount of salt per day from a statistical formula, as in Patent Document 4. Is also known.

It is important to measure a person's core body temperature to manage their physical condition, but since urine is released after being accumulated in the bladder at the core of the body, its temperature reflects the core body temperature. Therefore, if it is possible to accurately measure a person's deep body temperature from urine, it is considered to be effective for the use of physical condition management. As a device for measuring the urine temperature, a device has been proposed in which a temperature measuring unit is provided in the toilet bowl and the temperature of urine passing through the temperature measuring unit is measured (see, for example, Patent Document 5).

Japanese Patent No. 5553315 JP, 2016-178966, A International publication WO/2016/152847 Japanese Patent No. 37126396 JP-A-63-171933

Kotaro Yamasue, et al., "Study on Measuring Salt and Potassium Intake at Home," Journal of Daily Circulation Prevention 2004, 39, pp. 157-163.

However, the urine flow meter of the type to be installed in the toilet bowl as described above has a problem that a large amount of equipment cost must be invested for installation, and moreover, the urine flow rate can be measured (measured) only with a specific toilet bowl. There is also a problem. Similarly, also in the method of measuring the core body temperature, as described in Patent Document 5, in the above-described method of measuring the temperature of urine passing through the temperature measuring unit by providing a temperature measuring unit in the toilet bowl, There is a problem that the core body temperature can be detected only with a specific toilet bowl.

On the other hand, the urine volume measuring method of storing urine in a container and measuring the urine volume does not require urine collection in a specific toilet bowl, but as described above, a method for examining weight change using a load cell is not handled. There is a problem that it is difficult to do, and the method of storing urine in a container such as a cup and then measuring the amount of urine has sometimes been disliked due to odor. Further, in measuring urine without storing it in a container, the urine flow meter described in Patent Document 1 is a urine flow meter to which an ultrasonic Doppler method is applied, but it is used by being attached to a finger. It has not been put into practical use due to poor handling and poor accuracy. The urine flowmeters described in Patent Documents 2 and 3 have good usability, but cannot detect the salt content and the like.

Further, each of the conventional urinary salt concentration measuring methods has the following problems. For example, in the method of measuring the Na ion concentration of urine stored in a container, it is necessary to use an expensive analyzer for measuring the Na ion concentration, or to request the analysis institution to analyze the urine collected. Therefore, there is a problem that it is very difficult to measure the salt concentration in urine. In addition, the method of estimating the daily salt content based on the collected night urine, etc., has insufficient accuracy due to individual differences in the relationship between the night urine and the 24-hour urine, and an accurate salt content estimation cannot be performed. However, the method for estimating the amount of salt excretion from spot urine to urine per day cannot be measured at home, and its accuracy is insufficient.

The present invention has been made to solve the above problems, and the purpose thereof is to collect the urine at the time of urination in a container so that its flow rate and flow velocity can be easily measured, for example, even at home. A urine flow meter that is easy to use and that can easily and accurately detect the urinary salt concentration, and that can be used widely for medical purposes with the detection results of urine volume and salt content. In view of the above, it is preferable to provide a combined urine flow meter that can detect the urine temperature and can widely use the detection result of the urine temperature for medical purposes.

In order to achieve the above-mentioned object, the present invention has the following constitution as means for solving the problems. That is, a first aspect of the present invention includes the urine collecting part for collecting urine discharged from the urine, and the conduit body having a urine flow path through which the urine collected by the urine collecting part flows. A flow path communicates with the urine collection unit, and a urine flow rate detection sensor for detecting the flow rate of urine introduced from the urine collection unit into the duct body and flowing through the urine flow channel in real time is provided in the duct body. In the duct body, a concave portion is formed at a portion on the downstream side of the urine flow from the position where the urine flow rate detecting sensor is arranged, in which a part of the urine flowing through the urine flow passage of the duct body is collected. The urinary salt concentration detection sensor for detecting the salt concentration in urine accumulated in the recess is provided as means for solving the problem.

In addition, in a second aspect of the invention, in addition to the configuration of the first aspect of the invention, the urine flow rate detection sensor has a water wheel that is rotated by the flow of urine flowing through the urine flow path of the conduit body, A rotation detecting means for detecting rotation information of the water turbine is provided.

Further, in a third aspect of the invention, in addition to the configuration of the second aspect of the invention, a rotating body having a rotating shaft coaxial with the water turbine is provided outside the conduit body, and the rotation detecting means rotates the rotating body. It is characterized in that it is formed with a rotation detection sensor for detecting information by light.

Further, in a fourth aspect of the invention, in addition to the configuration of the second aspect of the invention, the rotation detecting means is formed by a rotation detecting sensor using a composite magnetic wire that causes the rotation information of the water wheel to cause a large Barkhausen jump phenomenon. It is characterized by

Furthermore, a fifth aspect of the invention is, in addition to the configuration of any one of the second to fourth aspects of the invention, the conduit body has a vertical urine flow path in which a urine flow flows in a vertical direction with respect to the water turbine. The outlet side of the urine flow path from the water turbine to the urine discharge part of the conduit body serves as a path for converting the flow path of the flow of urine in a lateral direction. Is provided on the bottom wall of the flow channel obtained by converting the flow channel to the lateral direction.

Further, in a sixth aspect of the present invention, in addition to the configuration of any one of the first to fifth aspects, the urinary salt concentration detecting sensor detects a urinary conductivity corresponding to a core body temperature of the urine collector. And a sodium ion concentration detection electrode for detecting the sodium ion concentration in urine corresponding to the core body temperature of the urine collector, and at least one detection electrode is formed. It is characterized by

Furthermore, a seventh aspect of the invention is, in addition to the configuration of any one of the first to sixth aspects of the invention, a hand-held lever portion on the side opposite to the side where the conduit body is disposed in a manner of sandwiching the urine collection portion in the longitudinal direction. Is installed upright, the angle sensor for detecting the tilt angle of the hand-held lever part with respect to a predetermined reference axis, and the tilt angle detected by the angle sensor when the urine collector collects urine in advance. And an informing unit for informing an appropriate angle situation when the angle is within the determined appropriate angle range.

Further, in addition to the configuration of any one of the first to seventh inventions, an eighth invention is characterized in that the conduit is provided in a portion of the conduit which is on the downstream side of the urine flow with respect to the urine flow rate detecting means. A recess for accommodating a part of urine flowing through the body is formed, and a urine temperature detection sensor for detecting the core body temperature of the urine collector by detecting the temperature of urine is provided in the recess. And

Further, a ninth invention is, in addition to the configuration of any one of the first to eighth inventions, a urine flow rate calculating means for calculating a urine flow rate based on detection information detected by the urine flow rate detection sensor. A salt concentration calculating means for calculating a urinary salt concentration based on detection information detected by the urinary salt concentration detection sensor, and a deep part of the urine collector based on the detection information detected by the urine temperature detection sensor At least one of the deep body temperature detecting means for detecting the body temperature is provided.

Furthermore, in addition to the configuration of any one of the first to ninth inventions, detection information detected by the urine flow rate detection sensor, detection information detected by the urinary salt concentration detection sensor, and It is characterized in that an information signal transmitting section for transmitting at least one piece of information detected by the urine temperature detecting sensor to an external receiving section is provided.

According to the present invention, when urine is excreted from a urine collector by the urine collection unit, the urine is introduced into a duct body having a urine flow channel and flows through the urine flow channel, and the flow rate of the urine is It is possible to detect in real time via a urine flow rate detection sensor provided in the duct body. Moreover, according to the present invention, in the conduit body, a portion of the urine flowing through the conduit body is provided in a concave portion provided at a site on the downstream side of the urine flow with respect to the arrangement position of the urine flow rate detection sensor. Since a sensor for detecting the salt concentration in urine for detecting the salt concentration in the collected urine is provided, the salt concentration in the urine (the deep part of the urine collector is detected through the sensor for detecting the salt concentration in urine). The salt concentration corresponding to the body temperature) can also be detected in real time.

That is, the present invention can detect the amount of urine collected by the urine collecting unit and flowing through the urine flow path of the duct body in real time, rather than storing the urine in a container such as a cup and measuring the amount of urine. Therefore, in addition to keeping the urine flow meter itself clean, unlike the case of measuring the urine volume by storing it in a container, odor and hygiene problems can be avoided, and the urine salt concentration detection sensor is used to detect urine. Since the salt concentration in the product can also be detected, it is possible to provide a combined urine flow meter with a very high utility value, which enables the detection results of both to be widely used for medical purposes.

That is, there is a strong demand for a urine flow meter that is small and lightweight and can be used at home and is easy to handle. However, the composite urine flow meter of the present invention can meet such a requirement, for example, in a housing for elderly people or It is possible to obtain appropriate urine flow rate information by keeping the combined urine flow meter of the present invention in a facility or the like and detecting the urine flow rate information for a certain period. Then, depending on the information, in addition to being able to confirm the therapeutic effect and early detection of urination disease, most people do not know their salt intake, Since the accuracy is poor, it can be used for grasping the required salt intake, and can be useful for treating or preventing diseases related to salt intake such as hypertension and heart disease.

The shape and the like of the composite urinometer of the present invention are not particularly limited, but for example, a hand-held lever portion can be formed upright on the side opposite to the side where the conduit is disposed. By doing so, it is possible to collect a urine in a hand-held state and provide a user-friendly combined urine flow meter.

Further, in the present invention, the urine flow rate detection sensor can be formed with a simple configuration by configuring the urine flow rate detection sensor with a water turbine that is rotated by the flow of urine flowing through the conduit body. By detecting the rotation information of the water turbine by the rotation detecting means, it is possible to easily enable accurate urine flow rate detection.

Further, in the present invention, a configuration is provided in which a rotating body having a rotation axis coaxial with the water turbine is provided outside the conduit body, and the rotation detecting means has a rotation detecting sensor for detecting rotation information of the rotating body by light. With this configuration, it is possible to accurately detect the rotation of the water turbine with a simple structure that enables weight reduction, and it is possible to accurately detect the urine flow rate. Further, since the rotating body and the rotation detecting sensor are provided outside the conduit body, maintenance can be easily performed.

Further, in the present invention, the rotation detecting means is formed of a rotation detecting sensor using a composite magnetic wire that causes a large Barkhausen jump phenomenon to generate the rotation information of the water turbine, so that the rotation speed is related to the rotation speed of the water turbine. Therefore, it is possible to obtain a pulse voltage of a certain magnitude, and it is possible to accurately detect the rotational speed of the water turbine regardless of the rotational speed of the water turbine. Further, since the rotation detecting means having this configuration can detect ultra-low speed rotation, the urine flow rate of the minimum flow rate can be reliably measured, so that the urine flow rate can be accurately measured. Furthermore, since the sensor itself does not require a power source because it generates radio waves, it can be used easily without connecting the flowmeter to a power source, and a built-in device such as a battery or a device-mounted power source can also be used. Since it is unnecessary, the flowmeter can be downsized and maintenance can be easily performed.

Further, in the present invention, the conduit body has a vertical urine flow path in which a urine flow flows in a vertical direction with respect to the water turbine, and urine from the water turbine to a urine discharge part of the conduit body. The outlet side of the flow path is a path for converting the flow path of the flow of urine in the lateral direction, and the recess is provided in the bottom wall of the flow path that has converted the flow path to the lateral direction. The following effects can be achieved with the existing ones.

That is, since the pipe body has a vertical urine flow path in which the urine flow flows in the vertical direction with respect to the water turbine, the urine flow flows in the vertical direction and appropriately hits the water wheel, thereby rotating the water wheel. However, the outlet side of the urine flow path from the water turbine to the urine discharge part of the conduit body constitutes a path for converting the flow path of the flow of urine in the direction toward the lateral direction, and on the lateral side thereof. By forming a concave portion equipped with a sensor for detecting the concentration of urinary salt in the bottom wall of the flow channel after converting the flow channel, most of the urine is smoothly discharged from the urine discharge part, and only a part is accumulated in the concave part. The urinary salt concentration can be accurately detected through the urine salt concentration detecting sensor provided in the recess.

Furthermore, in the present invention, the urinary salt concentration detection sensor is a conductivity detecting electrode for detecting urinary conductivity corresponding to the core body temperature of the urine collector, and urine corresponding to the core body temperature of the urine collector. At least one of the conductivity detection electrode and the sodium ion concentration detection electrode is formed by having at least one detection electrode of the sodium ion concentration detection electrode for detecting the sodium ion concentration in It is possible to accurately detect the salt concentration in urine by using the electrode. In particular, the conductivity detecting electrode is still inexpensive at present, does not require calibration for each measurement, and has a long life. Therefore, an inexpensive composite urinary flow meter can be realized and maintenance is easy.

Furthermore, in the present embodiment, a composite urine flow meter is constructed by providing a configuration in which a hand-held lever part is erected on the side opposite to the side on which the conduit body is arranged in a manner that the urine collection part is sandwiched in the longitudinal direction. It can be used by hand. Further, an angle sensor for detecting an inclination angle of the hand-held lever portion with respect to a predetermined reference axis, and the proper angle range in which the inclination angle detected by the angle sensor when a urine collector collects is predetermined. By having a configuration that has an informing means for informing the proper angle condition when inside, it is possible to prompt the user to use the handheld lever portion in a state in which the handheld lever portion is inclined to the proper angle, and The urine flow rate can be detected more accurately.

Further, in the present embodiment, a concave portion for accumulating a part of urine flowing through the duct body is formed in the duct body at a site on the downstream side of the urine flow from the urine flow rate detecting means, and the urine is formed in the concave portion. By providing a urine temperature detection sensor for detecting the core body temperature of the urine collector by detecting the temperature of the urine, every time the urine collector collects urine with the combined urine flow meter, the core body temperature of the urine collector is It is possible to detect the temperature through the temperature detecting sensor. By making it possible to measure the deep temperature of the urine collector for each urination through the urine temperature detecting sensor, the symptoms such as infectious diseases can be quickly known. The deep body temperature can be detected for each urination as the deep body temperature of the urine collector, for example, the temperature at which the peak temperature rises with the progress of urine collection.

Further, in the present embodiment, based on the urine flow rate calculation means for calculating the urine flow rate based on the detection information detected by the urine flow rate detection sensor, and the detection information detected by the urinary salt concentration detection sensor In the one provided with at least one of the salt concentration calculating means for calculating the urinary salt concentration and the deep body temperature detecting means for detecting the deep body temperature of the urine collector based on the detection information detected by the urine temperature detecting sensor The urine flow rate can be calculated in real time, the urinary salt concentration can be calculated, and the core body temperature of the urine collector can be calculated by the combined urinometer. Therefore, for example, by configuring the composite urometer to display those values, a urine collector can view at least one of the displayed values of urine flow rate, salinity, and core body temperature on the composite urometer. It is possible to be able to grasp each urine collection.

Furthermore, in the present invention, at least one of the detection information detected by the urine flow rate detection sensor, the detection information detected by the urine salt concentration detection sensor, and the detection information by the urine temperature detection sensor In the case where the information signal transmitting section for transmitting the information to the external receiving section is provided, based on the information transmitted from the information signal transmitting section, by the information analysis means or the like provided on the external receiving section side, Various analyzes can be performed based on the transmitted information.

In other words, the user simply urinates with a urine flow meter each time he/she urinates, and at least one piece of detection information regarding the urine flow rate, urine volume, urinary salt concentration, and urine temperature can be transmitted to the outside. It is possible to grasp at least one of urine flow rate, urine volume, urinary salt concentration, and urine temperature externally based on the detected information. It can be appropriately used for early detection, prevention of hypertension, physical condition management, and the like. In addition, for example, it can be used for nursing care afterwards in an elderly facility or the like, and a wider and more effective use of information can be performed.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic sectional view showing an embodiment of the combined urine flow meter according to the present invention. As shown in the figure, the composite-type composite urine flowmeter 1 of the present embodiment includes a urine collecting section 2 for collecting urine to be discharged and a urine flow path 3 through which urine collected by the urine collecting section 2 flows. And the formed conduit body 4. The conduit body 4 is bent in the middle, and is formed in such a manner that the direction is changed from the vertical direction in FIG. 1 to the horizontal direction in the middle. A urine flow path pipe 20 through which urine flows is provided on the upper end side in the conduit body 4, and the urine collection part 2 communicates with the urine flow path 3 of the conduit body 4 via the urine flow path pipe 20. There is.

The urine inlet side of the upper end side (obliquely upper left side in the figure) of the urine collecting part 2 is formed in a curved shape (curved surface shape) so as to be arranged in the vicinity of the urinary organ in a manner that fits in the urinary organ of the user. Since the urine collecting part 2 is formed in such a shape, it can be fitted to the vicinity of a human urinary organ (urine discharging part) to collect urine. However, it has a shape that makes it easy to collect urine and prevents urine from scattering.

A urine flow rate detection sensor 6 including a water turbine 7 is provided in the conduit body 4 on the lower end side of the urine flow path pipe 20, and the urine flow rate detection sensor 6 is provided from the urine collecting unit 2 to the conduit body 4. It functions as a sensor for detecting the flow rate of urine introduced into the urine and flowing through the urine flow path 3 in real time. The water turbine 7 is rotated by the flow of urine flowing out of the urine flow path tube 20, has eight blades 8 made of plastic such as PEEK (polyether ether ketone), and is formed to have a diameter of 30 mm, for example. The urine flow path 3 has a vertical portion in which the urine flow flows in the vertical direction with respect to the water turbine 7 (in the use state, for example, the vertical direction with respect to the floor). (A water turbine 7 is provided in the vertical urine flow path portion that flows toward the urine), and the outlet side of the urine flow path 3 from the water wheel 7 to the urine discharge part 30 of the conduit body 4 laterally flows the urine. It constitutes a path for converting the flow path in the direction toward the direction.

Further, as shown in FIG. 3, a disk 9 which is a rotating body coaxial with a water wheel (impeller) 7 and a rotation axis is provided outside the conduit body 4, and rotation information of the disk 9 is detected by light. A rotation detection sensor (optical sensor) 10 is provided, and a rotation detection unit that has the rotation detection sensor 10 and detects rotation information of the water turbine 7 is formed. In this embodiment, when the urine collected by the urine collecting unit 2 hits the blades 8 of the water wheel 7 and the water wheel 7 rotates, the disk 9 as a rotating body rotates together with the rotation of the water wheel 7. When light passing through the slit 11 of the disk 9 is detected by the rotation detection sensor (optical sensor) 10 as the disk 9 rotates, the light passage interval blocked by a portion other than the slit 11 is shown in FIG. It is measured (measured) by such a pulse number measuring device 12. That is, the rotation information of the disk 9 is detected by the rotation detection sensor 10 and measured by the pulse number measuring device 12.

For example, the correlation between the measurement value (the number of pulses) by the pulse number measuring device 12 and the urine flow velocity passing through the urine flow path 3 is obtained in advance, and is actually measured by the pulse number measurement value 12 when measuring the urine flow rate. Based on the measured value and the correlation, the urine flow velocity for each urine collection (urine flow rate for each time) can be obtained. Further, the total urine flow rate can be measured by integrating the number of measurement pulses. The pulse number measuring device 12 may be a part of the combined urometer 1 as an aspect of being attached to the outside of the conduit body 4, or may be provided separately from the combined urometer 1, and the pulse number measuring device 12 of the rotation detection sensor 10 may be provided. The sensor information may be wirelessly transmitted to the pulse number measuring device 12.

In addition, when the pulse number measuring device 12 is provided in the combined urine flow meter 1, the urine flow rate calculating means for calculating the urine flow rate from the measured value may be provided in the combined urine flow meter 1, or the pulse number measurement device. The 12 measured values may be wirelessly transmitted to the external urine flow rate calculating means to obtain the urine flow rate by the external urine flow rate calculating means. Further, in addition to the combined urine flow meter 1, a pulse number measuring device 12 is provided outside, and detection is performed by the rotation detection sensor 10 as the water wheel 7 of the urine flow rate detection sensor 6 is rotated by the urine flow. Information is wirelessly transmitted to an external pulse number measuring device 12, the number of pulses is measured by the pulse number measuring device 12, and the urine flow rate is calculated based on the value by an urine flow rate calculating means provided outside. Good.

As shown in FIG. 1, the conduit body 4 is provided with a concave portion 13 at a portion of the downstream side of the urine flow from the position where the urine flow rate detection sensor 6 is arranged, in which a part of the urine flowing through the conduit body 4 is collected. Has been formed. The recess 13 is provided on the bottom wall of the flow path obtained by converting the flow path to the lateral direction, and the depth of the recess 13 is, for example, about 10 mm. As shown in FIG. 2, the depression 13 is provided with a polyethylene resin cell 14 having a depth of 7.5 mm. The cell 14 is provided for detecting the salt concentration in the urine collected in the depression 13. A urine salt concentration detecting sensor 15 and a urine temperature detecting sensor 16 for detecting the temperature of urine are provided.

The urinary salt concentration detection sensor 15 is formed by having two pairs of electrodes 18 screen-printed with a silver chloride paste on a substrate 17 provided at the bottom of the cell 14, and the electrodes 18 are It functions as a conductivity detecting electrode for detecting the urinary conductivity corresponding to the deep body temperature. When urine accumulates in the concave portion 13, a current flows between the electrodes 18, so that the urine conductivity is detected from the current value. The value when the urine conductivity value (conductivity value corresponding to the salt concentration) rises and becomes saturated after the urine flows out of the urine flow path 3 is the urinary salt concentration corresponding to the core body temperature of the urine collector. Is obtained as an electric conductivity value corresponding to.

Then, it is possible to obtain the excreted salt concentration in urine for each time from the previously obtained formula of the relation between the electrical conductivity of urine and the salt concentration and the electric conductivity value for each urination. The urine amount calculated based on the rotation of the water wheel 7 is added to the salt concentration to obtain the urinary salt amount for each urination. In addition, the amount of salt excretion for each urination is integrated as a daily value to be calculated as the daily amount of salt excretion (the combined urine flow meter 1 of the present embodiment is portable, Since it is possible to easily detect the urine flow rate and the salt concentration, the urine amount and the salt concentration are calculated for each urination in one day, and the salt amount for each urination is calculated. By adding it, it is possible to accurately determine the daily amount of excreted salt).

It should be noted that although a circuit for obtaining the urine conductivity from the value of the current flowing between the electrodes 18 and a circuit for obtaining the salt concentration from the urine conductivity value as described above may be provided in the composite urinometer 1, in the present embodiment, it will be described later. As described above, the current value flowing between the electrodes 18 is transmitted to the outside by communication, and the urinary conductivity and the salt concentration in urine are calculated by an external device based on the current value.

The urine temperature detecting sensor 16 is formed by installing a thermistor as a temperature sensor at the bottom of the wall of the cell 14. The combined urine flowmeter 1 may be provided with a temperature display section and the detection value of the urine temperature detection sensor 16 may be displayed on the temperature display section. It may be transmitted wirelessly to the temperature display means provided outside the flow meter 1 and displayed by the temperature display means. When the temperature indicator is provided in the combined urinary flow meter 1, it is provided, for example, at a portion indicated by reference numeral 32 in FIG.

Unlike the surface temperature of the human body, the deep body temperature is a parameter indicating the original state of the human body, which is unlikely to be affected by the external environment, and is therefore suitable for measuring circadian rhythm and checking the physical condition. However, in general, in order to measure the core body temperature, it is necessary to measure the rectal temperature, the eardrum temperature, and the like. Since such a measuring method imposes a load, a measuring method alternative to such a measuring method is desired. The composite urine flowmeter 1 of the present embodiment can meet the above-mentioned demand because the core body temperature of the urine collector can be detected very easily via the urine temperature detecting sensor 16 every time the urine collector collects urine. It is possible and very convenient for managing the physical condition of the urine collector.

As shown in FIGS. 1 and 4, a hand-held lever portion 5 is erected on the side opposite to the side where the conduit body 4 is disposed so as to sandwich the urine collecting portion 2 in the longitudinal direction. In the urine flow meter 1, a urine flow meter holder 31 having a handheld lever portion 5 and a main body of a composite urine flow meter are integrally formed, and are electrically connected (for detecting urine flow rate). The detection information of the sensor 6, the salt concentration detection sensor 15, and the urine temperature detection sensor 16 is added to the circuit in the handheld lever unit 5 so that it can be transmitted to the outside by a transmitting unit described later).

The urine flow meter holder 31 is provided with an angle sensor 19 for detecting a tilt angle of the hand-held lever portion 5 with respect to a predetermined reference axis (for example, the X axis, Y axis, and Z axis in FIG. 4 in this embodiment). Has been. Further, when the urine collector collects urine, the LED display unit as a notifying means for notifying the angle proper situation when the tilt angle detected by the angle sensor 19 is within a predetermined proper angle range is a urine flow meter holder 31. The LED of the LED display unit is turned on when the tilt angle is within the proper angle range. The reference axis is appropriately set, and the notification means may be formed by a display section other than the LED display section, or may be a type of notification by voice.

In the present embodiment, with the above configuration, even if the urine flow rate characteristic changes depending on the angle of the combined urine flow meter 1 at the time of urine collection, urine can be collected within the range of the appropriate angle, so that the urine flow rate can be accurately detected. .. The urine flow meter holder 31 may be detachable from the combined urine flow meter 1, but when collecting urine, urine is collected in a state integrated with the combined urine flow meter 1, and the urine flow rate, the urinary salt concentration, and the urine temperature are collected. Are respectively detected.

Further, when the urine flow meter holder 31 and the main body of the composite urine flow meter 1 are connected, the height position of the main body of the composite urine flow meter 1 may be switched stepwise. Then, the mounting height of the composite urometer 1 can be adjusted according to the user's body shape and preference, and urine can be collected well. The height adjusting structure is not particularly limited and may be omitted or may be continuously adjustable.

Further, in the present embodiment, as shown in FIGS. 1 and 4, the inner peripheral wall of the urine collecting part 2 is provided with a rotary flow-down suppressing guide 35 formed by a convex part. The distal end portion of the rotary flow-down suppressing guide 35 formed in the center is formed to be slanted in a taper shape, and is spaced from the urine introduction port of the urine flow path tube 20. The rotary flow-down suppression guide 35 flows downward from the upper side to the lower side of the inner peripheral wall of the urine flow tube 20 without flowing down (without forming turbulent flow) while urine to be collected is rotating. It is collected on the side of the urine inlet and is made to flow down.

That is, when urine is introduced into the urine collecting section 2, the urine introduced into the center side of the urine collecting section 2 flows down in a state of being along the central flow-down suppression guide 35. The urine introduced on both sides of the center also collides with the rotary flow-down suppressing guide 35 and then flows down along the central rotary flow-down suppressing guide 35. In any case (whether the urine is introduced in any direction or angle), the urine is collected at the distal end side of the central rotary flow-down suppression guide 35 and flows along the tapered shape of the distal end portion. It is introduced into the urine flow conduit 20 along the inner wall of the conduit 20 and is forcibly vertically flowed down, so that it is introduced into the urine flow conduit 20 at approximately the same time.

The configuration of the urine flow channel 20 is described in Patent Document 3 and is well known. Therefore, although detailed description is omitted in this specification, the urine flow channel 20 has a blade-shaped partition plate 24 on the upper end side. The nozzle portion 22 is provided, and the distal end side of the conduit is obliquely cut off to form a nozzle portion 22 having an opening 21 formed therein, and urine introduced into the urine flow path pipe 20 is guided to a guide 23 provided in the nozzle portion 22. The blade is guided and flows down without rotating, and hits the tip of the blade 8 facing the tip of the nozzle portion 22 vertically or substantially vertically.

In the present embodiment, some urine directly hits the water turbine 7 without being guided by the guide 23 of the nozzle portion 22, but the urine also hits the tip side of the blade 8 of the water turbine 7. This is because the combined urine flow meter 1 of the present embodiment is designed so that the user holds the hand-held lever portion 5 so that the angle between the opening 21 of the nozzle portion 22 and the floor surface is vertical or nearly vertical. This is because the user can be held at an appropriate angle by checking the display on the LED display section as described above. The angle close to vertical as used herein is, for example, a range in which the angle difference from vertical is about 0° to 15°.

When the opening 21 of the nozzle portion 22 and the floor surface are arranged such that the angle between them is vertical or nearly vertical, the urine hitting the water turbine 7 directly without being guided by the guide 23 due to the large momentum is directly Then, it appropriately hits the tip of the blade 8 of the water turbine 7 at a vertical angle or an angle close to vertical. In addition, urine that flows down to the side peripheral wall side of the nozzle portion 22 and is guided (guided) by the guide 23 and jets (flows down) from the ejection port 36 at the tip of the nozzle portion 22 and hits the water wheel 7 also reaches the tip portion of the blade 8 of the water wheel 7. Hit appropriately. In other words, in any case, the urine appropriately hits the tip end of the blade 8 of the water wheel 7 in a pinpoint manner.

Then, the urine hits the water wheel 7 and the water wheel 7 rotates, and the rotation information of the water wheel 7 is detected by the rotation detecting means as described above, and the urine flow rate is detected based on the rotation detection information. That is, as described above, the disk 9 rotates with the rotation of the water turbine 7, light passes through the slit 11 of the disk 9, the number of pulses of the light passage is measured by the pulse number measuring device 12, and the urine is measured based on the value. The flow rate is detected.

FIG. 10 shows a schematic image diagram for explaining an example of a data analysis system using the combined urine flow meter of the embodiment. In this example, in the combined urine flowmeter 1 of the present embodiment, the detection information detected by the urine flow rate detection sensor 6, the detection information detected by the urine salt concentration detection sensor 15, and the urine temperature detection sensor. This is an example in which the handheld lever section 5 is provided with an information signal transmitting section for transmitting at least one piece of information (for example, all information) of the detection information detected by 16 to the receiving section of the external device.

In the figure, reference numeral 24 is a printer, reference numeral 25 is a smartphone, reference numeral 26 is a tablet with a wireless terminal, reference numeral 27 is a personal computer, reference numeral 28 is a label printer, and reference numeral 29 is a cloud. Note that low power blue source communication is used as a communication method. And, having such a communication function has an advantage that it can be useful for remote medical care and home medical care.

The present embodiment is configured as described above, and FIG. 5 shows a graph of an example of a urine flow rate curve and flow rate characteristics measured by the combined urinometer 1 of the present embodiment. The characteristic line a in the figure shows the urine flow rate characteristic, the characteristic line b shows the urine volume characteristic, and s in the figure is seconds. Further, FIG. 6 shows an example of the relationship between the urine volume obtained from the urine flow rate measured by the composite urinometer 1 of the present embodiment and the urine volume measured by the gravimetric method. In the figure, the characteristic line c is a straight line having a correlation function R of 1 between the urine volume obtained from the urine flow rate measured by the composite urinometer 1 of this embodiment and the urine volume measured by the gravimetric method.

As shown in FIG. 6, the urine volume obtained from the urine flow rate measured by the composite urinometer 1 of the present embodiment is substantially the same as the urine volume measured by the gravimetric method (correlation coefficient R is 1 (Which is 0.98 which is very close to the above), it was demonstrated that the urine flow rate can be accurately measured. In addition, in order to compare the urine flow measurement accuracy of the composite urometer 1 of the present embodiment with the gravimetric method, this figure shows that the urine discharged through the composite urometer 1 is received in a 1 L cup and the urine weight thereof is measured. And the urine volume obtained by dividing the weight value by the specific gravity of 1.005 and the urine volume measured by the composite urometer 1 of the present example.

Then, as shown in FIG. 5, the flow rate is obtained together with the flow rate by detecting the urine flow rate in time series, and based on the urine flow rate curve (characteristic line a), the urine collector causes prostatic hypertrophy or the like. It is possible to grasp the situation such as whether a person has a disorder such as urination disorder or bladder dysfunction, and whether there is almost any suspicion of these disorders. Note that FIG. 11 schematically shows a pattern example of urine flow rate data, and in the example shown in FIG. 5, it is considered that there is a suspicion of a disorder such as the urination disorder and the bladder dysfunction.

FIG. 7(a) shows another example of the urine flow rate curve and the urine volume characteristic measured by the composite urinometer 1 of this embodiment, and FIG. 7(b) shows a comparative example. An example of the urine flow rate characteristic and the urine volume characteristic in which the urine flow rate and the urine volume are measured by the change of the toilet water level is shown by the existing stationary urometer. The characteristic line a in FIG. 7A shows the urine flow rate characteristic, and the characteristic line b shows the urine volume characteristic. In addition, the characteristic line a in FIG. 7B shows the urine flow rate characteristic. Note that s in FIG. 7 is seconds. Looking at these results, the measurement accuracy of the comparative example is about ±10%, whereas the measurement accuracy of the composite urometer 1 of this embodiment is about ±5%. The measurement accuracy is higher than that of the comparative example, and minute changes can be detected.

As a means for detecting the salt concentration in urine, there are an electric conductivity method and an ion electrode method, as shown in Reference Document 1, but in the present embodiment, as described above, it is formed in the duct body 4. As the urinary salt concentration detecting sensor 15 for detecting the salt concentration in urine accumulated in the recess 13, the above-described electrode 18 is provided and the conductivity method for determining the urinary conductivity is applied. The reason is as follows.

Other electrolytes (potassium, calcium, magnesium salts, etc.) are contained in urine, and these electrolytes act to expel sodium salts in the human body and are excreted in the urine together with sodium salts. It Therefore, unlike the detection of the salt concentration by the ion electrode method that detects the sodium ion itself, when the conductivity in urine is detected, it will be affected by the conductivity of the electrolyte. By correcting the measured value, the salt concentration in urine can be accurately detected.

That is, as shown in the point of FIG. 8A, the correlation between the measured value of urinary salt concentration measured by the conductivity method and the measured value of urinary salt concentration measured by the ion electrode method is It can be represented by a correlation equation (Y=0.61(X) ^1.05 ) where Y is the value measured in step S and X is the value measured by the electrode method. Therefore, by correcting the value measured by the electrode method with this correlation formula, the result of detecting the salt concentration by the ion electrode method and the salt concentration by the conductivity method are detected as shown in the point of FIG. 8(b). With respect to the result, it is possible to obtain a high correlation with a correlation coefficient R of 0.92 for the characteristic line c having a correlation coefficient R of 1. In FIGS. 8(a) and 8(b), p indicates the risk rate, and N indicates the number of people who have detected the salt concentration.

FIG. 9 shows the relationship between the results obtained by determining the salt content in urine for 24 hours by the ion electrode method and the results obtained by determining the salt content in urine for 24 hours by the conductivity method for 188 adults by dots. The correlation coefficient is 0.91 with respect to the characteristic line c having the correlation coefficient R of 1, and the average values are 9.9±3.9 g and 9.8±3.6 g, showing a significant difference. There wasn't. Further, the conductivity is low in cost, and there is an advantage that maintenance such as calibration is unnecessary. That is, in this embodiment, by applying the method of detecting and correcting the urinary salt concentration by the conductivity method, the urinary salt concentration can be accurately detected, and the usability is good and the cost is low. Type urinometer can be realized.

In addition, according to the Japanese hypertension guideline, the upper limit of the daily salt intake of an adult is 6 g, and the measurement result obtained by the conductivity method by the combined urometer 1 of this example is less than 6 g as a starting point. The sensitivity was 0.977 and the specificity was 0.8. That is, although the specificity of the person less than 6 g to be less than 6 g is not sufficient, the sensitivity of the person more than 6 g to more than 6 g is high, and it is effective for the instruction of salt reduction.

In addition, there are individual differences in the sodium/potassium ratio, and some people have a significantly low value of 1.5 or less, and some people have a significantly high ratio of 8 or more. Thus, the proportion of people with a significantly low sodium/potassium ratio and the proportion of people with a very high sodium/potassium ratio is a low value of 10% or less of the whole, but since there are commercially available devices that measure the ratio of sodium and potassium in urine, If a device having a ratio of 1.5 or less and a ratio of 8 or more is used and the value measured by the conductivity method is corrected as in the present embodiment, a substantially correct salt concentration can be obtained, which is more accurate. The amount of excreted salt can be calculated.

Table 1 shows an example of urine volume, urine flow rate characteristics, excreted salt content, and urine temperature for each urination measured by the composite urometer 1 of this example. Daily urine output was 1600 ml and salt excretion was 7.2 g. The amount of the salt was measured by the gravimetric method, which was measured at the same time.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and various modes can be adopted without departing from the technical scope of the present invention. That is, the present invention is constructed by variously combining the constituent parts of the above-described embodiment. Hereinafter, some other embodiments will be described, but as for the embodiments not included in this description, as described above, various configurations such as those of the claims are possible within the scope not departing from the technical scope of the present invention. It is possible to adopt various aspects such as the construction by combining the above.

For example, in the above-described embodiment, the urinary salt concentration detection sensor 15 is formed in the mode as shown in FIG. 2A, but as shown in FIG. 2B, the cells 14 face each other. It is also possible to form the substrate 17 provided on the inner wall of the side portion having two pairs of electrodes 18 screen-printed with, for example, a silver chloride paste so that the urinary conductivity can be detected.

Further, in the above-described embodiment, the urinary salt concentration detecting sensor 15 is configured to detect the urinary salt concentration using the conductivity method, but a flat electrode type ion sensor as shown in Reference Document 1 is used. Alternatively, the salt concentration may be detected by the ion electrode method, provided by being provided in the cell 14 in the recess 13 of the combined urometer 1 in the above-mentioned embodiment. As the ion sensor, a sodium ion concentration detection electrode for detecting the concentration of sodium ions in urine corresponding to the core body temperature of the urine collector and a potassium ion concentration as described in Reference Document 1 are detected. If both of the electrodes for detecting potassium ion concentration are provided and the salt concentration is detected by the ion electrode method, not only the amount of excreted salt but also the amount of excreted potassium (70-80% of the ingested amount is excreted in urine) It is also measurable.

In this way, if a potassium ion electrode is also provided, potassium ion in urine can be detected, and potassium is effective in lowering blood pressure, which leads to guidance on intake of vegetables and fruits, which contain a large amount of potassium. On the other hand, not only sodium but also potassium and other electrolytes that can be reduced as much as possible will lead to the prevention and treatment of renal patients, and the effect of reducing dialysis patients is expected. Therefore, the urometer, which has been rarely used by anyone other than a urologist in the past, is likely to be used in cardiology, nephrology, diabetes, neurology, obstetrics and gynecology, general medicine, and the like. In addition, since the flat electrode type ion sensor has a disadvantage that the cost is high and the calibration is required once a day, it is considered preferable to apply the conductivity method at present, but in the future, Therefore, if the cost and performance of the ion sensor can be reduced, the utility value of the ion electrode method will increase.

Further, in the above-mentioned embodiment, the depth of the concave portion 13 is set to 10 mm, but the depth of the concave portion 13 is not particularly limited and is appropriately set.

Further, in the above-mentioned embodiment, as the rotation detecting means for detecting the rotation of the water turbine 7, the disk 9 as shown in FIG. 3 and the rotation detecting sensor (optical sensor) 10 for detecting the rotation information of the disk 9 by light are provided. However, the configuration of the rotation detecting means is not particularly limited and may be appropriately set. For example, various proximity switches or sensors using hall elements may be applied, and various types may be used. Applicable. For example, the rotation detection means may be formed by a rotation detection sensor using a composite magnetic wire that causes the large Barkhausen jump phenomenon to generate rotation information of the water turbine. Since this configuration is described in Patent Document 3 and is well known, detailed description thereof will be omitted. For example, a magnet is provided at the tip of the blade 8 to accelerate urine passing through the urine flow tube 20. Can be converted into an angular velocity of rotation of the water turbine 7, detected by a pulse rotation detection sensor generated by the rotation of the water turbine 7, and the urine flow rate can be detected based on the rotation information.

Furthermore, when the urine flow rate and urine volume, the urinary salt concentration, and the urine temperature are detected using the combined urine flow meter of the present invention, for example, data is recorded for each urination, and the wake-up time and bedtime are separately set. (For example, see Table 1). A system may be formed in which the data processing device automatically forms a urination diary for each date, and in this case, it is possible to create a diagnostic guideline regarding symptoms and diseases, and Applications (for example, treatment of diseases, application to nursing care, etc.) are also possible. For example, the patterns of the urine flow rate data examples as shown in FIG. 11 are accumulated in advance, and the time series created based on the data examples and the data obtained by the measurement with the combined urometer 1 By comparing with the urine flow rate graph, it is possible to create a diagnostic guideline regarding symptoms and diseases.

Note that the urine flow rate information is not limited to the information in the form of a graph, and may be table data or may be a list of numerical values. Any form may be used. Also, regarding the urinary salt concentration and the urine temperature, various usages are applied to the medical field, the nursing field, etc. due to the accumulation of data.

Further, in the combined urine flow meter of the present invention, the diameter and length of the urine flow conduit 20 and the nozzle portion 22 provided in the conduit body 4 are not limited, and may be set appropriately. The size and the like of the urine flow path tube 20 are appropriately formed, for example, in accordance with the size of the conduit body 4, but the urine flow path tube 20 has a urine flow path through which urine flows without stagnation. When the nozzle portion 22 as in this embodiment is formed on the tip end side thereof and the opening portion 21 and the guide 23 are provided in the nozzle portion 22, the same effect as that of the above embodiment can be obtained. ,desirable. The urine flow conduit 20 may be omitted.

Furthermore, in this embodiment, the urine collecting section 2 is provided with the convex-shaped rotational downflow guide 35, but the rotational downflow guide 35 may be formed with a recess, or the rotary downflow guide 35 may be formed. It can be omitted. However, it is preferable to provide the rotational downflow guide 35. The shape and size of the urine collecting part 2 of the combined urinary flow meter 1 are not particularly limited, and are appropriately set so that urine from the urinary organs of the user can be satisfactorily collected.

Further, the water wheel 7 of the urine flow rate detecting sensor 6 applied to the combined urine flow meter 1 is not limited to the one applied in the above embodiment, and the number, size, shape, etc. of the blades 8 are appropriately set. Is.

Further, in the above-mentioned embodiment, the combined urine flow meter 1 has a hand-held lever and is used by hand, but it may be attached to a toilet bowl by providing a set stand or the like. Although urination at the sitting position is in a state in which the posture of the user is regulated, the urine collecting unit 2 is arranged in the vicinity of the urine collecting unit 2 so as to fit the urine collecting unit of the user due to the curved configuration of the urine collecting unit 2 ( Or contact the urinary organs).

The present invention makes it possible to easily measure the flow rate and the flow rate of the urine during urination without collecting it in a container, for example, at home, etc. Therefore, it can be used for detecting urinary disorders, etc., and it is also possible to detect the urinary salt concentration corresponding to the core body temperature of the urine collector in real time, which enables detection of core body temperature. There is also. Therefore, it is likely to be used mainly in urology, cardiology, nephrology, diabetes, neurology, obstetrics and gynecology, general medicine, etc. Can increase the possibility of use.
