Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

An early warning device for detecting bladder urine based on ultrasound, as shown in Figure 1, includes:

Ultrasonic module 1, connected with ultrasonic transducer 7, for transmitting ultrasonic waves and receiving ultrasonic signals reflected by the bladder;

The control module 2 is connected with the ultrasonic module 1, and is used for obtaining the urine content in the bladder based on the ultrasonic signal reflected by the bladder;

Also includes:

The wireless data transceiver 3 is connected to the control module 2 for sending the obtained urine content;

The early warning terminal 4 is connected to the wireless data transceiver 3 through a wireless channel, and is used for receiving the urine content and performing urination warning based on the urine content.

The collected urine content is stored in a memory.

The control module 2 includes an analog-to-digital converter 21 and a controller 22 . The input end of the analog-to-digital converter 21 is connected to the ultrasonic module 1 , the output end is connected to the controller 22 , and the controller 22 is connected to the wireless data transceiver 3 .

The early warning device further includes a USB interface 5 which is connected with the controller 22 .

The device uses a rectangular circuit board as the main board, the size of the circuit board is 20mm*30mm*1mm, and the medium substrate is used as the substrate. The top layer of the medium substrate is the installation location of the hardware circuit and button battery, and the bottom layer of the medium substrate is the Bluetooth/WiFi antenna and ultrasonic wave. Transducer installation location. The device is small in size, easy to insert into other products (eg belts), simple in structure and easy to use.

As shown in FIGS. 2 to 4 , the early warning device further includes a medium substrate 6 , the ultrasonic module 1 , the control module 2 and the wireless data transceiver 3 are all arranged on the top layer of the medium substrate 6 , and the ultrasonic transducer 7 is located on the bottom layer of the medium substrate 6 . The bottom layer of the medium substrate 6 is also provided with a data transceiver antenna 8 , and the data transceiver antenna 8 is connected to the wireless data transceiver 3 .

The early warning terminal 4 is a hand-worn terminal, and the hand-worn terminal includes an annular body and a vibrator arranged in the annular body. The annular body includes a base unit and at least one optional unit in which the vibrator is located.

In this application, since the early warning device only needs to simply compare the collected urine content with the preset value, the software part is implemented based on the existing software, and the core improvement point of this application is to provide a separate detection part The early warning terminal is designed as a hand-worn terminal (such as a smart bracelet), so as to solve the problem that the urination warning cannot be effectively perceived by the user.

In this application, the ultrasonic module and the control module can be in the same manner as CN 107072634 A, which will not be repeated here, and the wireless data transceiver part can use TL8723BSA, which integrates Bluetooth and WiFi. The wireless data transceiver part of the bracelet can also use TL8723BSA, and the vibrator part can use TM6163 as the driver chip.

The device has an on-off button 101 to control the on-off of the power supply path of the power source 10, and the power source 10 adopts a button battery. The power supply 10 provides the power required by the whole device, and supplies power to each part except the early warning terminal. Press the power button 101 to start the device. At this time, the button battery provides DC power to each module in the device. After the module is powered on, it enters the system and the device starts to work.

When starting to work, the device will first transmit an ultrasonic wave, and the electrical signal will be converted into an ultrasonic signal after passing through the ultrasonic transducer, and then transmitted to the bladder. To receive, the ultrasonic transducer 7 will convert the ultrasonic signal into an electrical signal for reception. The transmission and stop of the ultrasonic electrical pulse signal are controlled by the controller 22 of the control module 2 of the device. After multiple echo acquisitions, the electrical signal is sent to the chip for amplification and filtering, and then provided to the A/D converter (A/D converter: analog-to-digital converter) to convert into a digital signal, and the digital signal enters the controller 22 to perform analysis to calculate the percentage of bladder volume occupied by urine in the bladder, which generally guarantees an accuracy of ±5%.

After the controller 22 obtains the proportion of urine, it will automatically save the detection information in the built-in memory 9, and when the memory 9 is full, new information automatically overwrites the old information. At the same time, the information detected each time is sent to the mobile phone or other terminal devices via the low-power WiFi/Bluetooth module. Set the corresponding equipment parameters, such as acquisition time and alarm threshold. If the proportion of urine in the bladder is higher than the set threshold (this value can be manually set by the mobile phone or terminal device, the default value is 80%), the mobile phone or terminal device will be triggered to generate an early warning, and the user or his guardian will be notified in time. urination.

In order to avoid abnormal situations such as no signal received or other sudden interference, the device will perform 3 pre-scans before formally collecting data. If the three results differ by 10% (or other values), re-scan . If the difference between the results of the three pre-scans is less than 10%, the system will carry out formal data collection, and the formal collection will be repeated 10 times, which is also due to the consideration of the low power consumption strategy.

The default working mode of the device is continuous monitoring every 15 minutes, and the monitoring time interval can be set according to personal conditions and background data information; under the default working mode, the device's battery life is about 72 hours.

When the user is in a scenario without a WiFi network, the Bluetooth mode is enabled by default. The first use requires a terminal device or a mobile phone to be paired with the device. After the pairing is successful, the Bluetooth/WiFi module of the device will actively communicate with the mobile phone or other terminal devices; when When the user is in a Wi-Fi scenario, the device will automatically connect to the Wi-Fi hotspot and enter the Wi-Fi mode, and the guardian can realize long-distance real-time monitoring through the mobile phone or terminal device, and help the wearer to urinate in time. When in a scenario where WiFi and Bluetooth are available at the same time, the Bluetooth connection will be the priority for the sake of power saving. After the connection is successful, control and data transmission can be performed.

The device can realize real-time monitoring of the urine volume of the wearer's bladder, and users can flexibly set monitoring and alarm strategies according to personal conditions, effectively reducing the occurrence of urinary incontinence in the elderly and children, reducing the user's discomfort caused by urinary incontinence, and realizing long-distance Monitoring and alarming can remind users and guardians in time to facilitate the care of the guardians.
