Description

Smart urine flow detection system and method

The present invention relates to the field of detection, and in particular, to an intelligent urine flow detection system and method.

Urine testing is one of the common ways to evaluate the health status of the body, and urinary flow testing is one of the test items in the urine test. Uroflow testing is a convenient, simple, non-invasive and non-contact test that can assess whether a patient's urinary system is normal. The urinary flow testing device is used to perform urinary flow testing and has been widely used in medical institutions. Medical staff can use the urinary flow curve and other parameters measured by the urinary flow testing device to determine whether the patient is suffering from urinary diseases (such as prostate cancer, chronic prostatitis, urethral stricture, chronic cystitis, lower urinary tract infection, urinary dysfunction, etc.).

Generally speaking, a urinary flow testing device includes a funnel, a urine storage container, and a uroflowmeter. When the user or patient performs a urinary flow test, the user or patient first urinates into the funnel, and then the funnel guides the urine to the urine storage container. Finally, the uroflowmeter calculates the changes in urine volume in the urine storage container to generate urine. Flow detection results. However, the urinary flow testing devices currently on the market are all independent devices. After the user or patient's test is completed, the urine contained in the urine storage container needs to be manually poured out and cleaned before it can be used by the next user, thereby increasing labor costs and reducing convenience. Furthermore, since urine is excrement and may contain many germs, if urine flow testing If the funnel and urine storage container of the device are not cleaned regularly, the cleanliness of the environment will be reduced.

Please refer to Figure 1, Figure 2 and Figure 3 together. Figure 1 illustrates an embodiment according to the present invention Structural diagram of the smart urine flow detection system 1 of the embodiment. FIG. 2 is a cross-sectional view of the smart urine flow detection system 1 according to FIG. 1 . FIG. 3 is a functional block diagram of a smart urine flow detection system 1 according to an embodiment of the present invention. The smart urine flow detection system 1 of the present invention is used to measure the urine volume data of the urine discharged by the user. As shown in FIGS. 1 to 3 , in this specific embodiment, the smart urine flow detection system 1 includes a toilet 10 , a main control box 11 , a urine storage box 12 and a uroflowmeter 13 . The main control box 11 is coupled to the toilet 10 and located above the toilet 10 . The urine storage box 12 is arranged below the toilet 10 . The uroflowmeter 13 is connected to the bottom of the urine storage box 12 . Further, the main control box 11 includes a sensor 111 and a controller 112, and the controller 112 is connected to the sensor 111 and the uroflowmeter 13.

In this specific embodiment, the toilet 10 has a guide outlet 101, the urine storage box 12 has an accommodation space 120, and the guide outlet 101 communicates with the accommodation space 120. The toilet 10 is used to receive urine discharged by the user and guide the urine to the urine storage box 12 through the guide outlet 101, and the accommodation space 120 of the urine storage box 12 is used to accommodate and store the urine discharged by the user. liquid. In practice, the toilet 10 can be a urinal, and the urinal can be hung and fixed on the wall. The guide outlet 101 may be located at the bottom of the urinal, and the urinal may further include a conduit 102 communicating with the guide outlet 101 and the accommodation space 120 of the urine storage box 12 . The urine storage box 12 includes a main body 121 and an upper cover 122, and the upper cover 122 is detachably provided on the main body 121. The upper cover 122 of the urine storage box 12 may include a urine collection port 123 communicating with the accommodation space 120 . Further, the catheter 102 of the urinal can pass through the urine collection port 123 of the urine storage box 12 . Therefore, the user can urinate into the urinal, and the urinal can collect urine so that the urine passes through the guide outlet 101 and the conduit 102 and flows into the urine storage box 12 . It is worth noting that the toilet in this specific example is a urinal, but in practice, it is not limited to this. The toilet can also be a structure, component or device that collects and guides urine.

In this specific embodiment, the uroflowmeter 13 is used to measure the weight of the urine storage box 12 to calculate the urine flow rate and urine volume data corresponding to the urine discharged by the user. In practice, urine flow The scale 13 may include a weight sensor 131 , and the weight sensor 131 is used to contact and carry the urine storage box 12 . When the user urinates into the urinal, the urine continues to pass through the catheter 102 and flows into the urine storage box 12. At this time, the weight sensor 131 of the uroflowmeter 13 continues to measure the weight of the urine storage box 12 to calculate The flow rate of urine in the urine storage box 12, that is to say, the uroflowmeter 13 can measure the flow rate of urine discharged by the user, and thereby generate urine volume data corresponding to the user.

It is worth noting that, as shown in FIG. 2 , the size of the urine collection port 123 of the urine storage box 12 is larger than the outer diameter of the catheter 102 of the urinary tract, and the weight sensor 131 can be located on the upper edge of the body of the uroflowmeter 13 The position is such that there is a gap between the urine storage box 12 and the body of the uroflowmeter 13 . That is to say, the urine storage box 12 only contacts the weight sensor 131 of the uroflowmeter 13 and does not contact other components. Therefore, the uroflowmeter 13 can truly measure and calculate the user's urine output data without being affected by other components, thereby improving accuracy.

In this specific embodiment, the sensor 111 of the main control box 11 is used to detect the user. Wherein, the use signal is generated when the sensor 111 senses the user, and the leaving signal is generated when the sensor 111 does not sense the user and reaches the time length threshold. In practice, the sensor 111 may be an infrared sensor, and the emitting tube of the infrared sensor may emit infrared rays to sense the surroundings of the urinal. When the user is urinating in the urinal, the user can reflect the infrared rays emitted by the transmitting tube, and the receiving tube of the infrared sensor can receive the infrared rays reflected by the user. At this time, the sensor 111 generates a usage signal; and when After the user finishes urinating and leaves the urinal, the receiving tube of the infrared sensor cannot receive the infrared rays emitted by the transmitting tube. At this time, the sensor 111 will record the length of time that the receiving tube does not receive the infrared rays. When the length of time When the time length threshold is reached, the sensor 111 generates an away signal. In practice, the time length threshold may be 5 seconds, but is not limited to this.

In this specific embodiment, the controller 112 of the main control box 11 responds to the sensor 111 The generated usage signal controls the activation of the uroflowmeter 13 , and transmits the urine volume data to the data processing device 5 according to the exit signal generated by the sensor 111 and the urine flow rate calculated by the uroflowmeter 13 . In practice, the controller 112 may be a central processing unit (CPU) or a control chip. When the controller 112 receives the usage signal generated by the sensor 111, the controller 112 will determine that the user is in front of the urinal and wants to urinate. At this time, the controller 112 controls the uroflowmeter 13 to start and simultaneously monitors the urine flow rate calculated by the uroflowmeter 13 . Further, the controller 112 may pre-store the time length threshold. When the controller 112 receives the departure signal generated by the sensor 111 and detects that the urine flow rate calculated by the uroflowmeter 13 is 0, and the controller 112 detects that the urine flow rate is 0 for a time period of When the length threshold is reached, the controller 112 will determine that the user has finished urinating and leaves the urinal. At this time, the controller 112 controls the uroflowmeter 13 to transmit the urine volume data to the data processing device 5 . In practice, the time length thresholds prestored by the sensor 111 and the controller 112 may be the same.

In practice, the uroflowmeter 13 may further include a transmission module 132 connected to the weight sensor 131, and the data processing device 5 may be a smart phone, a cloud server or a remote host. The transmission module 132 can be a signal transmitter and can transmit the urine volume data calculated by the weight sensor 131 to the data processing device 5 through wireless transmission (such as Bluetooth, Wi-Fi, ZigBee, etc.). For example, the user's smartphone can be equipped with an application corresponding to a urometer or a medical institution. When the user finishes urinating and leaves the urinal, the controller can control the uroflowmeter to transmit the urine volume data to the user's smartphone via Bluetooth transmission; in another embodiment, when the user finishes urinating and leaves the urinal, After using the urinary duct, the controller can control the urinometer to transmit the urine volume data to the cloud server or remote host of the medical institution through Wi-Fi transmission, so that medical staff can keep track of the user's physiological condition at any time. Furthermore, medical staff can also analyze the urine output data stored in the cloud server or remote host and generate an analysis report, and then send the analysis report to the user's smart phone. machine.

Furthermore, the main control box 11 may also include an identification module 113 for confirming the user's identity and generating a confirmation signal. In practice, the identification module 113 may include a sensor chip and a storage unit, and the storage unit may pre-store the user's identity information. When the user wants to perform a urine flow test, the user can first bring the magnetic card storing the identity information close to the sensor chip using Near Field Communication (NFC). When the sensor chip reads the identity data in the magnetic card and determines that the identity data in the magnetic card matches the identity data in the storage unit, the sensor chip generates a confirmation signal. In another embodiment, the recognition module may include a camera, a face recognition chip, and a storage unit, and the storage unit may pre-store the user's characteristic data. When the user wants to perform urine volume detection and is in front of the urinal, the camera can first capture the user's face image. When the face determination chip determines that the facial image captured by the camera matches the characteristic data in the storage unit, the face determination chip generates a confirmation signal. After the controller 112 receives the usage signal generated by the sensor 111 and the confirmation signal generated by the identification module 113 at the same time, the controller 112 then controls the uroflowmeter 13 to start. In addition, when the controller 112 controls the uroflowmeter 13 to transmit urine volume data to the data processing device 5 , the controller 112 may also transmit the user's identity data corresponding to the urine volume data to the data processing device 5 .

See Figure 1 to Figure 4. Figure 4 is a flowchart illustrating the steps of a smart urine flow detection method according to a specific embodiment of the present invention. The step flow of the smart urine flow detection method in Figure 4 can be achieved by the smart urine flow detection system 1 in Figures 1 to 3 . As shown in Figure 4, the operation process of the smart urine flow detection system 1 of the present invention includes: Step S1: whether the sensor 111 detects the user. If the detection result is no, return to step S1 and continue detection; if the detection result is yes, execute step S2: the sensor 111 generates a usage signal; step S3: the identification module 113 confirms the user's identity and Generate a confirmation signal; step S4: the controller 112 controls the uroflowmeter 13 to start based on the use signal and the confirmation signal. Step S5: The uroflowmeter 13 measures the weight of the urine storage box 12 to calculate the urine flow rate and urine volume data; Step S6: The controller 112 determines whether it receives the departure signal generated by the sensor 111, the uroflowmeter 13 The calculated urine flow rate is 0 and the length of time the urine flow rate is 0 reaches the time length threshold. If the judgment result is no, return to step S6 and continue detection; if the judgment result is yes, step S7 is executed: the controller 112 controls the uroflowmeter 13 to transmit the urine volume data to the data processing device 5 .

In practice, when the user wants to perform a urine flow test, the sensor 111 of the smart urine flow test system 1 will detect the user to generate a usage signal, and the identification module 113 will confirm the user's identity and generate a confirmation. signal, and the controller 112 will control the activation of the uroflowmeter 13 according to the use signal and the confirmation signal. When the user urinates, the toilet 10 of the smart urine flow detection system 1 will collect and guide urine into the urine storage box 12, and the uroflowmeter 13 will continuously measure and calculate the urine flow rate and instant urine flow rate of the urine storage box 12. Quantity data. When the user finishes urinating and leaves, the sensor 111 of the smart urine flow detection system 1 does not detect the user for a certain period of time and generates a leaving signal, and the urine flow rate calculated by the uroflowmeter 13 is 0. When the time comes, the controller 112 controls the uroflowmeter 13 to transmit urine volume data corresponding to the user to the data processing device 5 . Therefore, the smart urine flow detection system of the present invention can combine the toilet and the urinary flowmeter, allowing the user to urinate in the toilet urinal while also conducting urine flow detection, thereby improving efficiency, convenience and cleanliness, and Reduce labor costs. Moreover, the smart urinary flow detection system of the present invention can identify the user corresponding to the urine volume data generated by the uroflowmeter through the identification module, thereby improving detection efficiency. It is worth noting that in another specific embodiment, when the smart urine flow detection system 1 is only used by a single user and only needs to measure the urine output data of a single user, the controller 112 can only control the urine flow according to the usage signal. The flow meter is activated without identifying the user's identity through the identification module.

As shown in Figures 1 to 4, in this specific embodiment, the smart urine flow detection system 1 It further includes a water outlet pipe 14 and a first control valve 151 . The water outlet pipe 14 is connected to the accommodation space 120 of the urine storage box 12 . The first control valve 151 is disposed between the water outlet pipe 14 and the urine storage box 12 and is connected to the controller 112 . In practice, the urine storage box 12 may include a water outlet 124 connected to the accommodation space 120 and located on the side wall of the body 121 of the urine storage box 12 . One end of the water outlet pipe 14 corresponds to the water outlet 124 , and the first control valve 151 is located between the water outlet 124 and the water outlet pipe 14 . Further, the other end of the water outlet pipe 14 is connected to the sewage pipe 7 . When the controller 112 receives the departure signal generated by the sensor 111 and controls the uroflowmeter 13 to transmit urine volume data corresponding to the user to the data processing device 5, the controller 112 can control the first control valve 151 to open, so as to The urine in the urine storage box 12 is allowed to flow through the outlet pipe 14 to the sewage pipe 7 . Therefore, the smart urine flow detection system of the present invention can automatically discharge the urine in the urine storage box through the controller controlling the valve without manual cleaning, thereby improving convenience and reducing labor costs. It is worth noting that, as shown in FIG. 2 , the outer diameter of the water outlet pipe 14 is smaller than the size of the sewage pipe 7 . That is to say, the urine storage box 12 will not come into contact with the sewage pipe 7 . Therefore, the uroflowmeter 13 can truly measure and calculate the user's urine output data without being affected by the traction or pulling force of the sewage pipe 7, thereby improving accuracy.

Further, the smart urine flow detection system 1 may include a water inlet pipe 16 and a water inlet valve 161. The water inlet pipe 16 can be connected to the top of the urinal, and the water inlet valve 161 is disposed in the water inlet pipe 16 and connected to the controller 112 . In practice, one end of the water inlet pipe 16 can be connected to the top of the urinal, and the other end of the water inlet pipe 16 can be connected to a water supply tank (not shown). The water supply tank can provide cleaning water, and the controller 112 can control the water inlet valve 161 to open so that the cleaning water passes through the water inlet pipe 16 and flows to the urinal. As shown in FIG. 4 , after the smart urine flow detection system 1 executes step S7 , step S8 can be further executed: the controller 112 provides cleaning water according to the departure signal generated by the sensor 111 to clean the urine storage box 12 . In practice, after the uroflowmeter 13 transmits the urine volume data to the data processing device 5, the controller 112 can control the water inlet valve 161 and the first control valve 151 to open at the same time. At this time, the urine contained in the urine storage box 12 passes through the water outlet The pipe 14 flows to the sewage pipe 7, and the cleaning water provided by the water supply tank can also flow through the water inlet pipe 16, the urinal, the urine storage box 12 and the outlet pipe 14 in sequence and flow to the sewage pipe 7 to simultaneously clean the urinal and Urine storage box. Therefore, the smart urine flow detection system of the present invention can also control multiple valves through the controller to achieve the function of automatically cleaning the toilet and urine storage box, thereby improving cleanliness and convenience.

Additionally, the controller 112 may prestore a speed threshold. When the controller 112 controls the first control valve 151 to open and the flow rate calculated by the uroflowmeter 13 is less than the flow rate threshold, the controller 112 generates a warning signal. In practice, the flow rate threshold may correspond to the flow rate of the water outlet pipe 14 . In a preferred embodiment, the flow rate threshold may be slightly smaller than the flow rate of the water outlet pipe 14 . When the user test is completed and the controller 112 controls the first control valve 151 to open, the controller 112 can continue to monitor the flow rate of the urine storage box 12 detected by the uroflowmeter 13 . When the flow rate calculated by the uroflowmeter 13 is less than the flow rate threshold, it means that the water outlet 124 or the water outlet pipe 14 of the urine storage box 12 may be blocked by foreign matter. At this time, the controller 112 generates and sends a warning signal (as shown in step S9 and step S10 in FIG. 4 ). In addition, when the controller 112 controls the water inlet valve 161 to open to provide cleaning water to the urine storage box 12 and controls the first control valve 151 to open, the controller 112 can also continuously monitor the flow rate of the corresponding cleaning water calculated by the uroflowmeter 13 . When the flow rate of the corresponding cleaning water calculated by the uroflowmeter 13 is less than the flow rate threshold, the controller 112 generates a warning signal. The warning signal can be text, sound, color, light, etc., and the controller 112 can also send the warning signal to the data processing device 5 to alert the user or medical institution personnel. The user or medical institution personnel can also open the upper cover 122 of the urine storage box 12 to confirm whether there is any foreign matter in the urine storage box 12 . Therefore, the smart urine flow detection system of the present invention can have the function of obstruction detection through flow detection, thereby improving efficiency and convenience.

In a specific embodiment, the controller 112 can also pre-store a weight threshold. When the controller 112 controls the first control valve 151 and the water inlet valve 161 to open and the urine storage measured by the uroflowmeter 13 When the weight of the box is greater than the weight threshold, the controller 112 generates a warning signal. In practice, when the user test is completed and the controller 112 controls the first control valve 151 and the water inlet valve 161 to open, the controller 112 can continuously monitor the weight of the urine storage box 12 measured by the uroflowmeter 13 . When the weight measured by the uroflowmeter 13 is greater than the weight threshold, it means that the water outlet 124 or the outlet pipe 14 of the urine storage box 12 may be blocked by foreign matter, causing the cleaning water to be unable to flow to the sewage pipe 7 and accumulate in the urine storage box 12 . At this time, the controller 112 generates and sends a warning signal to alert the user or medical institution personnel (as shown in step S9 and step S10 in FIG. 4 ). While the controller 112 generates a warning signal, it can also control the water inlet valve 161 to close. Therefore, the smart urine flow detection system of the present invention also has the function of detecting overflow of the urine storage box, thereby improving efficiency and convenience.

In addition to the foregoing specific embodiments, the smart urine flow detection system of the present invention can also be in other forms. Please refer to FIG. 5 , which is a cross-sectional view of a smart urine flow detection system 2 according to an embodiment of the present invention. As shown in Figure 5, the difference between this specific embodiment and the previous specific embodiments is that the smart urine flow detection system 2 of this specific embodiment further includes a second control valve 252 and a third control valve 253 connected to the controller. And the sewage pipe 7 includes a first sewage pipe 71 and a second sewage pipe 72 . The first sewage pipe 71 is connected to the guide outlet 201 of the toilet 20 and the accommodation space 220 of the urine storage box 22 , and the third control valve 253 is provided in the first sewage pipe 71 .
