Description

Technical Field

[0001] The invention relates to an intelligent device and method for forming a urination diary of a urinary incontinence patient, which is used for diagnosing urinary incontinence patients and belongs to the field of medical devices or nursing products. Background Art

[0002] Urinary incontinence (UI) refers to the inability to control the spontaneous leakage of urine from the bladder. Urinary incontinence occurs in all age groups, especially in middle-aged and elderly women. It is considered by the World Health Organization to be one of the five major chronic diseases that threaten the physical and mental health of adult women. According to the etiology and clinical manifestations of urinary incontinence, the guidelines of the National Institute for Health and Clinical Excellence (NICE) in the United Kingdom divide urinary incontinence into four types: stress urinary incontinence (SUI), urge urinary incontinence (UUI) and mixed urinary incontinence (MUI).

[0003] Unlike symptoms such as tumors and stones, urinary incontinence can be diagnosed through color Doppler ultrasound, CT and other imaging or biochemical tests. Urinary diary is currently the main means of evaluating urinary incontinence. Urinary diary, also known as urination frequency or urine volume table, refers to the continuous recording of the patient's fluid intake, urination time, urine volume per time and urination frequency for 3 to 7 days without changing the patient's living conditions and urination habits. Urinary diary has important clinical significance for evaluating the specific situation of abnormal urination and symptomatic treatment. In the current urination diary, the commonly used method for recording urine volume is the urine pad weighing method. During the monitoring period, the patient is required to wear a diaper, weigh the diaper, measure and record the amount of urine discharged or leaked each time. However, the patient's manual measurement and recording for several consecutive days not only has great operational difficulty and work intensity, but also has poor privacy, affecting normal life and work. It can be seen that the existing technology for forming urinary incontinence urination diaries has great deficiencies. Summary of the invention

[0004] In order to solve the shortcomings of the existing technology for forming a urination diary for urinary incontinence patients, the present invention provides an intelligent device and method for forming a urination diary for urinary incontinence patients.

[0005] An intelligent device for forming a urination diary for patients with urinary incontinence, comprising a wearable urine volume monitoring device and a negative pressure suction material. Among them: The wearable urine volume monitoring device comprises a control mainboard, a vacuum pump, a pressure sensor, a urine volume measuring device, a posture sensor, a communication module, a terminal monitoring software, an internal power supply and a wearable fixing device.

[0006] The control motherboard is an integrated circuit constructed by components such as a core processor, memory, signal processor, and power module, and is prepared using conventional integrated circuit welding or patch technology.

[0007] The control mainboard is provided with embedded software, which is a software program for hardware driving, data monitoring, status prompting and negative pressure suction control, and the embedded software is burned into the memory of the control mainboard.

[0008] The vacuum pump is a negative pressure generating device that provides a vacuum environment inside the negative pressure suction material and drives urine drainage. The vacuum pump is connected and communicated with the control motherboard. In conventional applications, the maximum negative pressure capacity of the vacuum pump is not less than -20KPa.

[0009] The pressure sensor is used to dynamically monitor the pressure value applied by the vacuum pump to the negative pressure suction material. The range of the pressure sensor is not narrower than -20KPa~0, and the measurement accuracy is not less than 0.1KPa. The pressure sensor is connected and communicated with the control mainboard, and the pressure data obtained by dynamic monitoring is sent to the core processor.

[0010] The urine volume measuring device is used to dynamically monitor the amount of urine discharged by the patient each time, and the measuring range of the urine volume measuring device is not narrower than 0 to 1000 ml. The urine volume measuring device is connected and communicated with the control main board, and sends the urine volume data obtained by dynamic monitoring to the core processor. The urine volume measuring device uses, including but not limited to, radar level gauges, capacitive level gauges, ultrasonic level gauges and gravity sensors. The specific method is, for example, preparing the urine collector as a regular container, and setting a radar level gauge directly above the urine collector. When the radar pulse wave encounters the surface of the urine, it is reflected back and received by the receiver, and the distance signal is converted into a liquid level signal to calculate the urine volume in the urine collector. Alternatively, a gravity sensor is used, the urine collector is suspended under the gravity sensor, and the amount of urine discharged by the patient is dynamically weighed.

[0011] The measurement accuracy of the urine volume measuring device is affected when the patient is in an active state or the device is worn at a large inclination angle. The posture sensor is used to monitor the position status of the wearable urine volume monitoring device, including whether the dynamic monitoring device or urine collector is in a static state, including the horizontal state and inclination angle of the device or urine collector. The posture sensor uses a three-axis gyroscope or a six-axis gyroscope. The posture sensor is connected and communicated with the control motherboard, and sends the posture data obtained by dynamic monitoring to the core processor. After the patient urinates, when the posture sensor senses that the state of the device or urine collector deviates, it prompts the patient to remain static for a short time, so that the urine volume measuring device can accurately measure the urine volume.

[0012] The communication module uses WiFi or Bluetooth, and the communication module communicates remotely with the user terminal (including computer, iPad or mobile phone). In the working state, the communication module sends the equipment working status information and monitoring information to the user end, and can send a prompt or alarm signal when the urine collector exceeds the limit.

[0013] Terminal monitoring software is a software program installed on medical institutions or patient monitoring terminals, including PCs, iPads and mobile phones. Terminal monitoring software is used to input, display and count basic patient information, urination information and monitoring device operating status information.

[0014] The internal power supply is the power supply system of the urine volume monitoring device, and the internal power supply adopts a conventional rechargeable battery.

[0015] The wearable fixing device is used for wearing and fixing the urine volume monitoring device on the periphery of the human body. The external structure and material of the wearable fixing device are not limited, and it is suitable for the urine volume monitoring device to be comfortably worn and fixed on the periphery of the human body. For example, a belt-type, a strap-type, a vest-type or a bellyband-type structure can be used, and the preparation materials include but are not limited to cotton cloth, elastic cloth, chemical fiber products or other non-toxic polymer materials.

[0016] The negative pressure suction material is mainly composed of a leak-proof shell, an adsorbent material, a suction cavity, a drainage tube, a urine sensor and a urine collector. Among them: The anti-leakage shell is an isolation device that is convenient for patients to wear or fix around the urethral opening and prevent urine from leaking to the periphery. The anti-leakage shell is made of flexible materials including latex, silicone rubber, etc., and the specific shape of the anti-leakage shell is not limited. Preferably, according to the different shapes of the male and female vulva parts, combined with ergonomics and the convenience of wearing, the anti-leakage shell structure is divided into two forms for men and women. For example, the male anti-leakage shell adopts a sleeve-shaped or bag-shaped structure, which is worn and fixed around the penis, and the female anti-leakage shell adopts a bowl-shaped or disc-shaped structure, which is fixed upside down around the female urination opening.

[0017] The adsorbent material is a urine buffer and absorbent material that covers or wraps around the patient's urethral opening. When the patient urinates, the adsorbent material can quickly absorb the urine and divert it into the suction cavity to prevent the urine from overflowing from the periphery of the anti-leakage shell. The adsorbent material is arranged on the inner side of the anti-leakage shell and is fixed in a three-sided or annular structure, but at least one side of the adsorbent material should be exposed, and the exposed side is combined with the patient's urination opening.

[0018] The adsorbent material is made of flexible materials including medical non-woven fabrics (such as pure cotton spunlace fabrics, perforated hot air non-woven fabrics, perforated spunbond non-woven fabrics), sponges and chemical fiber fabrics. Preferably, the adsorbent material adopts a composite structure, the surface layer in contact with the urethra opening is made of medical non-woven fabrics, the inner layer is made of sponges or chemical fiber cotton, and the sponges or chemical fiber cotton are provided with diversion holes or diversion grooves inside.

[0019] The suction chamber is arranged at the downstream position of the anti-leakage shell, and the suction chamber is combined with the adsorbent material to gather the urine dynamically collected by the adsorbent material into the suction chamber. The shape of the suction chamber is not limited, and the internal volume is required to be at least 2ml-5ml. The suction chamber can be arranged separately downstream of the anti-leakage shell, or it can be integrally formed with the anti-leakage shell. For example, when preparing men's products, the anti-leakage shell adopts a cylindrical bag structure (similar to a condom structure) made of silicone material, and an elastic band or elastic ring is provided on the outer periphery of the bag. A cylindrical suction chamber is provided at the bottom of the bag, and the adsorbent material is arranged above the suction chamber. The volume of the suction chamber is 3ml-5ml.

[0020] The drainage tube is a flexible tube connecting the suction cavity and the urine collector. The head end of the drainage tube is connected to the inside of the suction cavity, and the end of the drainage tube is connected to the inner cavity of the urine collector. The drainage tube is made of medical soft polyvinyl chloride. Common technical parameters include, for example, an outer diameter of 5mm-6mm, a tube wall thickness of 0.5mm-0.6mm, and is required to withstand a negative pressure of ≥40cmH2O.

[0021] The urine sensor is a sensing device that senses the patient's urine discharge. The urine sensor is set in the inner cavity of the leak-proof shell or the inside of the suction cavity, and should be set in the part where urine must flow. The urine sensor includes a temperature sensor, a humidity sensor, an optical sensor, and a pH sensor. The urine sensor converts the change information when it comes into contact with urine or when urine penetrates into an electrical signal output through a sensitive element. The core processor senses the patient's start or end of urination by analyzing and processing the changes in the electrical signal.

[0022] Since the use of temperature sensors, humidity sensors, etc. to monitor the urination state is prone to response delay, causing urine to overflow after urination, and the use of infrared sensors, pH sensors, etc. for disposable drainage materials is relatively expensive. A preferred and simpler solution is that the urine sensor consists of a positive electrode, a negative electrode and a 2-core extension wire, and a connection terminal is provided at the end of the extension wire; the positive electrode and the negative electrode are arranged in space, and must not be short-circuited or touch each other. The positive electrode and the negative electrode are respectively arranged in the parts of the anti-leakage shell where urine must flow. For example, the positive and negative electrodes of the urine sensor are prepared as a two-pin pin or micro plug structure, and the rear end of the positive and negative electrodes is provided with a 2-core extension wire, and the end of the extension wire is provided with a connection terminal. The connection terminals used include DC connectors, USB connectors or audio connectors, and the connection terminals are connected to the control motherboard for communication. The positive and negative electrodes are arranged in the guide groove inside the adsorption material, or the positive and negative electrodes are arranged in the suction cavity. The positive and negative electrodes are arranged in spaced-apart layouts from left to right or from top to bottom, and the spacing between the positive and negative electrodes is not less than 1mm.

[0023] The urine collector is a device for collecting and temporarily storing urine. It is equipped with a liquid inlet, a negative pressure interface and a urination switch. The liquid inlet and the negative pressure interface are respectively arranged above the urine collector. The liquid inlet is connected to the end of the drainage tube, and the negative pressure interface is connected to the negative pressure port of the urine volume monitoring device through a negative pressure tube. The urination switch is arranged at the bottom of the urine collector, and is used to regularly discharge the urine collected in the urine collector.

[0024] The wearable urine volume monitoring device is used in combination with a negative pressure suction material, and a physical interface for combining with the negative pressure suction material is provided on the periphery of the wearable urine volume monitoring device. The physical interface includes an installation interface for quick combination of the wearable urine volume monitoring device and the urine collector; a sensor interface for connecting the wearable urine volume monitoring device to a urine sensor, which is arranged on the periphery of the control mainboard; a negative pressure interface for connecting the wearable urine volume monitoring device to the urine collector or drainage tube, which is connected to the negative pressure air path interface of the vacuum pump; and a pressure measurement interface for connecting the wearable urine volume monitoring device to the urine collector or drainage tube, which is connected to the pressure measurement port of the pressure sensor.

[0025] A method for forming a urination diary for a urinary incontinence patient, comprising: S1, using terminal monitoring software, bind the wearable urine volume monitoring device to the patient. After the patient logs in, he / she enters the basic information of the patient in the urination diary.

[0026] For example, the terminal monitoring software uses a mobile phone APP, and the wearable urine volume monitoring device uses WiFi or Bluetooth to communicate with the patient's mobile phone. The patient uses methods such as scanning code registration or Bluetooth automatic matching to bind the wearable urine volume monitoring device to the mobile phone. The patient fills in the patient's basic information (name, gender, age, etc.), daily water intake, etc. through the APP form requirements to form the basic information of the monitored patient.

[0027] S2, combines the wearable urine volume monitoring device with the negative pressure suction material, and the urine sensor, core processor and vacuum pump form a closed-loop feedback control circuit to establish a fast-response negative pressure suction control system. When the urine sensor senses that the patient's urine is discharged, the vacuum pump automatically starts working.

[0028] S3, during negative pressure drainage, the vacuum pump continues to work according to the pre-set negative pressure value. The pressure sensor dynamically monitors the negative pressure value in the urine collector or drainage tube and feeds it back to the core processor to achieve dynamic feedback adjustment of the negative pressure output by the vacuum pump, and prompts when the pressure is abnormal.

[0029] S4, after the urine sensor senses that the urine inside the anti-leakage housing is sucked out by the negative pressure, the vacuum pump automatically stops working, or the vacuum pump stops after a delay.

[0030] For example, the urine sensor senses that no more urine is discharged, but in order to further empty the residual urine in the negative pressure suction material (including adsorbent material or drainage tube) and keep the negative pressure suction material dry, the vacuum pump delays working for 1-5 minutes and then stops.

[0031] S5, after the vacuum pump stops working, the urine volume measuring device calculates the patient's urine volume this time and sends it to the terminal monitoring software.

[0032] S6, during urine volume measurement, the posture sensor dynamically monitors the position state of the wearable urine volume monitoring device, especially the tilt angle of the urine collector.

[0033] For example, since the urine collector is a regular container with a defined capacity, the posture sensor can correct the measurement accuracy through the software algorithm after knowing the inclination angle of the urine collector. However, if the patient is in an active state, the wearable urine volume monitoring device or the urine collector is in a state including shaking or too large an inclination angle, causing the urine volume measurement device to fail to work properly or exceeding the limit value corrected by the algorithm, the posture sensor sends monitoring information to the core processor, and the core processor sends a prompt message to the user terminal, prompting the user to temporarily keep the wearable urine volume monitoring device in an upright and stationary state.

[0034] S7, after each urine volume measurement is completed, an audio-visual prompt signal such as "this monitoring is completed" is given, and the urine volume measurement device automatically writes the acquired urination information into the urination diary and forms a statistical form. The urination information includes the urination start and end time and the urine volume of this time, and the urination information acquired in this monitoring is sent to the user terminal.

[0035] For example, the core processor records the trigger time of the urine sensor as the starting time of the patient's urination; and records the end time of the patient's urination according to the time when the urine sensor detects no new urine. The urination time format is XX year XX month XX day XX hour XX minute, or XX month XX day XX hour XX minute.

[0036] The wearable urine volume monitoring device automatically fills in the information of each urination into the mobile phone APP and automatically forms a complete urination diary. The content automatically written into the urination diary includes urination time, urine volume per time, number of urinations, cumulative urine volume for the day, and total urine volume. The total urine volume is the sum of urine volume from the day of wearing to the end of the entire cycle. The mobile phone APP can also communicate with the cloud monitoring platform of the medical institution and send the patient's urination diary to the cloud monitoring platform for medical staff to view.

[0037] S8, when the urine volume measuring device senses that the urine volume in the urine collector exceeds the safe capacity, for example, exceeds 80% of the approved capacity, the wearable urine volume monitoring device gives a prompt or warning message.

[0038] The beneficial effects of the present invention are: (1) A urine sensor is installed inside the anti-leakage shell of the negative pressure suction material. The urine sensor, core processor, and vacuum pump form a closed-loop feedback control circuit that can automatically sense the patient's urination status and quickly respond to start negative pressure suction. After urination, the vacuum pump automatically stops working or stops working after a delay, and the urine volume monitoring device returns to standby or dormant state. In particular, a urine sensor composed of a positive electrode, a negative electrode, and a 2-core extension wire is used. The monitoring sensitivity is high, which not only avoids the perception delay of conventional urine sensors and the urine overflow problem caused by negative pressure suction lag, but also the consumables prepared using the urine sensor are low in cost and have high medical and economic significance.

[0039] (2) The negative pressure suction of urine by a vacuum pump overcomes the limitation of the traditional urine gravity drainage technology that the urine collector must be combined in the downstream part of the human bladder. The urine collector can be worn at the patient's waist, which is more private and more convenient for patients to wear, move and dynamically monitor urine volume.

[0040] (3) Automatically measure the amount of urine voided, and automatically record the start and end time of urination, urine volume, and frequency of urination, automatically forming a true and effective urination diary. This greatly reduces the labor intensity of forming a urination diary and ensures the reliability and validity of the diagnostic results.

[0041] This technical solution fills the gap in this field and has great clinical promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] 4. The adsorption material 21 is made of polyurethane sponge and is cut by die stamping according to the internal shape of the anti-leakage shell 20. The adsorption material 21 is required to be fitted inside the anti-leakage shell 20 and not easy to fall out.

The chassis is circular, 3mm thick, 9mm in outer diameter, and a urine diversion hole with a diameter of 3.5mm is provided in the middle of the chassis. Circular electrode mounting holes with a diameter of 1.5mm are provided on the left and right sides of the chassis, and the electrode mounting holes are closely attached to the inner side of the urine diversion hole.

[0061] A copper wire with an outer diameter of 1.5 mm is cut into small sections with a length of 6 mm, and the positive and negative electrodes of the urine sensor 24 and the chassis are injection molded using a metal inlay injection molding process.

[0062] 2. Use a two-core extension wire 25, weld the heads of the extension wire 25 to the positive and negative electrodes of the urine sensor 24 respectively, and weld the ends of the extension wire 25 to the connection terminals 31 and combine them.

[0063] 3. Urine sensing method of urine sensor 24 (1) A closed-loop feedback control circuit is formed by using a urine sensor 24, a core processor and a vacuum pump. The positive electrode of the urine sensor 24 is connected to one of the pins of the core processor, and the negative electrode is connected to the D line in the control motherboard. The vacuum pump is controlled by the core processor.

[0064] (2) When the urine volume monitoring device 10 is in standby or dormant mode, the core processor loads a stable current, such as 3.3V current, to the positive electrode of the urine sensor 24, and dynamically monitors the voltage value of the negative electrode connected to the D line. When the patient starts to urinate, the adsorbent material 21 on the periphery of the urethral opening absorbs the urine and guides it into the anti-leakage shell 20 and flows through the urine sensor 24. Based on the good conductivity of urine, the positive and negative electrodes of the urine sensor 24 are connected by urine. The core processor detects that the voltage at the D line end where the negative electrode is located has a significant voltage increase compared to the initial voltage. For example, the voltage at the D line end rises from 0 to 2.2V-2.8V. The core processor immediately automatically starts the vacuum pump, and the vacuum pump works according to the pre-set negative pressure value to drain the urine into the urine collector 27.

[0065] (3) After the urine is adsorbed and emptied, the positive and negative electrodes of the urine sensor 24 are naturally disconnected, the voltage at the D line end where the negative electrode is located returns to 0, and the core processor instructs the vacuum pump to stop working.

[0066] Example 4 Application of a urine volume monitoring device and a negative pressure suction material for men 1. If Figure 2 After the methods shown are combined, the urine volume monitoring device 10 is tied to the patient's waist using the wearable fixing device 11, the anti-leakage shell 20 is fixed to the periphery of the patient's urethra, and the urine collector 27 is vertically hung directly below the gravity sensor.

Insert the connection terminal 31 of the urine sensor 24 into the sensor interface on the right side of the urine volume monitoring device 10 , and connect the tapered joint of the negative pressure tube 26 to the vacuum pump interface on the left side of the urine volume monitoring device 10 .

[0068] 3. Turn on the urine volume monitoring device 10, set the drainage negative pressure value to -40 cmH2O in the human-computer interaction interface, and the urine volume monitoring device 10 enters the working standby state.

[0069] 4. During the standby period, if the patient discharges urine, the adsorbent material 21 quickly absorbs the urine, and when the urine flows through the urine sensor 24, the core processor instructs the vacuum pump to start working, and the urine discharged by the patient is negatively pressured into the urine collector 27. During this period, the pressure sensor dynamically monitors the negative pressure value in the urine collector 27 or the drainage tube 22 and feeds it back to the core processor. According to the change of the negative pressure value, the core processor instructs the vacuum pump to dynamically correct the working pressure so that the negative pressure value is stably maintained within the set drainage negative pressure value range.

[0070] 5. After the urine sensor 24 learns that the patient has finished urinating, the core processor instructs the vacuum pump to stop working.

[0071] 6. The urine volume measuring device measures the amount of urine discharged by the patient this time, and displays the urine volume data and urination time on the human-computer interaction interface, and sends it to the customer's monitoring terminal at the same time.
