Technical Field

[0001] The present invention relates to a smart wearable device, in particular to a smart wearable device with bladder pressure detection. Background Art

[0002] When people reach a certain age, they will have some poor urination control. At first, they are reluctant to wear diapers. It is okay during the day, but when they are asleep at night, once they feel the urge to urinate, it is often too late. The present invention is a smart wearable device for bladder pressure detection. The device includes a pressure detection film, a Bluetooth communication unit and a smart watch. The pressure detection film is divided into a positive electrode for pressure detection output and a negative electrode for pressure detection output, and is connected to the Bluetooth communication unit at the same time. The Bluetooth communication unit has a computing module to obtain pressure data on the surface of the pressure detection film, which is transmitted to the smart watch through Bluetooth communication. The pressure data can be used to predict the pressure of the organ on the surface of the pressure detection film. The surface of the pressure detection film is waterproof and anti-fouling treated, and it is attached to one side of the flexible belt. The flexible belt makes the pressure detection film contact the skin, senses the pressure of the skin and the skin, generates pressure data, and transmits it to the smart watch through Bluetooth communication and displays it on the screen. The smart watch has both computing power and Bluetooth communication power. It is connected to the Bluetooth communication unit through the Bluetooth network to obtain pressure data, and displays or reminds the smart watch after computing and judging. The watch does not have to be worn to achieve the reminder function, so that the elderly can be reminded when the bladder urine increases, reducing the chance of bedwetting. Summary of the invention

[0003] This device is a smart wearable device with bladder pressure detection, which includes a pressure detection film, a Bluetooth communication unit and a smart watch. The pressure detection film is divided into a positive pressure detection output electrode and a negative pressure detection output electrode, and is connected to the Bluetooth communication unit at the same time; the Bluetooth communication unit has a calculation module to control the positive pressure detection output electrode and the negative pressure detection output electrode to obtain the surface pressure data of the pressure detection film, which is transmitted to the smart watch through Bluetooth communication and can predict the organ pressure of the pressure detection film contacting the surface based on the pressure data.

[0004] One is a pressure detection film, which is characterized by a waterproof and anti-fouling surface treatment. It is attached to one side of a flexible belt. The flexible belt allows the pressure detection film to contact the skin, sense the pressure of the skin and inside the skin, and generate pressure data through the Bluetooth communication unit. The data is transmitted to the smart watch through Bluetooth communication and displayed on the screen.

[0005] The second is a smart watch, which is characterized by having both a computing module and a Bluetooth communication module. It has both computing capabilities and Bluetooth communication capabilities. It is connected to the Bluetooth communication unit via a Bluetooth network to obtain pressure data, which is then displayed or reminded on the smart watch after computing and judgment.

[0006] The third is a Bluetooth communication unit, which has the feature of being able to replace the paired smart watch, or pair with multiple smart watches.

[0007] Among them, the preferred method is that a smart watch, based on comparison with previous data, issues a reminder of increased pressure, and the reminder methods include vibration reminder, sound reminder and wake-up word reminder.

[0008] Among them, the preferred method is that the pressure detection film is attached to the abdomen to determine the bladder pressure, and attached to the forehead to determine the brain pressure. It will give a sound reminder, but the accuracy will be affected by the attachment method, angle and environment, so it is not suitable as the only reminder method. The Bluetooth communication unit can determine serious wearing errors based on the data and use a smart watch to remind corrections.

[0009] Among them, the preferred method is that the Bluetooth communication unit is characterized by defining an upper pressure limit value. When the obtained pressure is below the upper pressure limit value, no data is transmitted, thereby extending the standby time. Through the setting of the smart watch, it is only turned on at the set time, thereby shortening the working time.

[0010] Among them, the preferred method is that the pressure detection film is characterized by a surface waterproof and anti-fouling treatment, which is attached to one side of the flexible belt, and the size of the pressure detection film and the flexible belt is changed according to the contact area with the skin.

[0011] Among them, the preferred method is a smart watch, which is characterized by having both a motion sensing component and a vital sign sensing component, which converts the obtained information into motion records and vital sign interpretations, which are stored and displayed on the smart watch.

[0012] Among them, the preferred method is a smart watch, which is characterized by having a displacement sensing component that can record the sleep state and the pressure detection film during sleep. The smart watch can be set to indicate whether a reminder is needed when the person is in deep sleep.

[0013] Among them, the preferred method is to attach the pressure detection film to a flexible belt and wrap it around the skin outside the bladder, so that the pressure detection film can sense the bladder pressure, so that when the bladder increases due to urine, the bladder pressure increases, and an early warning can be generated. In the past, there were two types of invasive and non-invasive methods for measuring bladder pressure. Invasive pressure measurement includes abdominal puncture catheterization and femoral vein catheterization pressure measurement. Non-invasive pressure measurement includes: inserting a nasogastric tube, rectal intubation, and inserting a urinary catheter into the stomach. Pressure measurement through a gastric tube and pressure measurement through a urethral catheter are suitable for adults, especially pressure measurement through a urethral catheter, which is commonly used in clinical practice at home and abroad. Cystometrometry is currently recognized as the "gold standard" for indirect measurement of intra-abdominal pressure. Rectal pressure measurement is mainly used for infants and young children, and cystometrometry is mainly introduced here. Cystometrometry includes pressure suit cystometrometry and simple cystometrometry. None of these methods are as simple and convenient as the present invention, which uses a pressure detection film attached to a flexible belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When the urine increases and the bladder pressure increases, the wearer can be actively reminded by sound or vibration to go to the toilet in advance and reduce the probability of bedwetting; 2. After reducing the probability of bedwetting, the sanitary environment is improved and the quality of life is improved; 3. After reducing the probability of bedwetting, conflicts and embarrassment among relatives and friends can be avoided: the quality of feelings is improved and there is no loss of face; 4. This function can be made into a third-party application (APP) and put into a smart watch to remind many daily needs, which can improve the quality and efficiency of life; 5. The pressure detection film is attached to a flexible belt and wrapped around the skin outside the bladder, so that the pressure detection film can sense the bladder pressure, so that when the bladder increases due to the increase of urine, the bladder pressure can generate an early warning; 6. It can increase the pressure mode judgment and serve as a snoring stopper. If the wearer is snoring, the watch will vibrate slightly, and the wearer will stop snoring reflexively.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 To achieve the above-mentioned purpose, the present invention provides the following technical solutions: The present invention is a smart wearable device with bladder pressure detection, such as Figure 1 and Figure 2 As shown, the smart wearable device includes a pressure detection film 10, a Bluetooth communication unit 40 and a smart watch 50, wherein the pressure detection film 10 is divided into a pressure detection output positive electrode 20 and a pressure detection output negative electrode 30, and is connected to the Bluetooth communication unit 40 at the same time; the Bluetooth communication unit 40 has a computing module, which controls the pressure detection output positive electrode 20 and the pressure detection output negative electrode 30 to obtain the surface pressure data of the pressure detection film 10, and transmits it to the smart watch 50 through the Bluetooth communication 45, so as to predict the pressure of the organ on the surface contacted by the pressure detection film 10 based on the pressure data.

[0019] One is a pressure detection film 10, such as Figure 3 As shown, the surface is treated with waterproof and antifouling, and is attached to one side of the flexible belt 60. The pressure detection film 10 is in contact with the skin 69 through the flexible belt 60 to sense the pressure of the skin and the bladder 70 in the skin. Figure 4 As shown, pressure data is generated via the Bluetooth communication unit 40, transmitted to the smart watch 50 via the Bluetooth communication 45, and displayed on the screen 52. The pressure detection film 10, as shown Figure 3 As shown, it is a resistive film pressure string dryer. The thickness of the flexible material can be less than 0.45MM, the size can be adjusted, and the shape can be long, square and round; it is waterproof and high temperature resistant. It can be converted into API or UART serial port through the collector and connected to the Bluetooth module; the more mature suppliers of this material are Changzhou Tiance Electronics and Wiki. This material is often used to make human seat sensors, flexible bending sensors, anti-snoring sensors, pressure transmitters, sleep monitoring belts, shoe type induction detectors, mold contact detection membranes and weight sensors.

[0020] The second is a smart watch 50, which is characterized by having both a computing module 52 and a Bluetooth communication module 54, and having both computing capabilities and Bluetooth communication capabilities. It is connected to the Bluetooth communication unit 40 via a Bluetooth network 45 to obtain pressure data, and displays or reminds the smart watch 50 after computing and judging.

[0021] The third is a Bluetooth communication unit 40, which is characterized in that it can replace the paired smart watch 50, or pair with multiple smart watches 50. Figure 5As shown, a Bluetooth communication unit 40 is paired with a smart watch 50, a second smart watch 51, and a third smart watch 53 at the same time. The Bluetooth communication unit 40 is passive and can only be paired with the last selected smart watch.

[0022] Among them, the preferred method is that the smart watch 50, such as Figure 6 As shown, based on the comparison between the current pressure data 82 and the previous pressure data 80, a pressure increase reminder 85 is given, and the reminder methods include vibration reminder, sound reminder and wake-up word reminder.

[0023] Among them, the preferred method is that the pressure detection film 10 is attached to the abdomen to determine the bladder pressure, and attached to the forehead to determine the brain pressure. It will give a sound reminder, but the accuracy will be affected by the attachment method, angle and environment, and it is not suitable as the only reminder method. The Bluetooth communication unit 40 can determine serious wearing errors based on the data and use the smart watch 50 to remind corrections.

[0024] Among them, the preferred method is as follows Figure 7 As shown, the Bluetooth communication unit 40 is characterized by defining an upper pressure limit 86. When the obtained pressure is below the upper pressure limit 86, data 88 is not transmitted. When the obtained pressure is above the upper pressure limit 86, data 88 is transmitted, the standby time is extended, and the smart watch 50 is set to turn on only at the set time, thereby shortening the working time.

[0025] Among them, the preferred method is that the pressure detection film 10, which is characterized by a surface waterproof and anti-fouling treatment, is attached to one side of the flexible belt 60, and the size of the pressure detection film 10 and the flexible belt 60 is changed according to the contact area with the skin.

[0026] Among them, the preferred method is that the smart watch 50 is characterized by having both a motion sensing component and a vital sign sensing component, which converts the obtained information into motion records and vital sign interpretations, which are stored and displayed on the smart watch 50.

[0027] Among them, the preferred method is that the smart watch 50 is characterized by having a displacement sensing component that can record the sleep state. When the pressure detection film 10 is in sleep, the smart watch 50 is set to whether a reminder is needed when sleeping soundly.

[0028] Among them, the preferred method is that when the urine increases and the bladder pressure increases, the wearer can be actively reminded by sound or vibration to go to the toilet in advance and reduce the probability of bedwetting. After reducing the probability of bedwetting, the sanitary environment is improved and the quality of life is improved. After reducing the probability of bedwetting, conflicts and embarrassment among relatives and friends can be avoided: the quality of feelings is improved, and there is no loss of face.

[0029] Among them, the preferred method is that this function can be made into a third-party application (APP) and put into a smart watch to remind many daily necessities, which can improve the quality and efficiency of life.

[0030] Among them, the preferred method is that the product features and applications of piezoelectric film have unique characteristics. As a dynamic strain sensor, it is very suitable for life signal monitoring on the surface of human skin or implanted in the human body. Some thin film elements are sensitive enough to detect human pulse through a coat. This article will focus on several typical applications of piezoelectric films in life sign monitoring. Chinese name Piezoelectric thin film sensor Foreign name Piezoelectric thin film sensor Features Dynamic strain Application Life signal monitoring Remarks Can withstand millions of times of bending and vibration.

[0031] Among them, the preferred method is that when you stretch or bend a piece of piezoelectric polyvinylidene fluoride PVDF polymer film (piezoelectric film), an electrical signal (charge or voltage) will be generated between the upper and lower electrode surfaces of the film, and it is proportional to the deformation of stretching or bending. General piezoelectric materials are sensitive to pressure, but for piezoelectric films, when a small force is applied in the longitudinal direction, a large stress will be generated in the lateral direction, while if the same force is applied to a large area of ​​the film, the stress generated will be much smaller. Therefore, piezoelectric films are very sensitive to dynamic stress, and the typical sensitivity of 28μm thick PVDF is 10~15mV / microstrain (parts per million change in length). The term "dynamic stress" is used because the charge generated by deformation will be lost from the circuit connected to the film, so piezoelectric films cannot detect static stress. When it is necessary to detect different levels of prestress, this becomes the advantage of piezoelectric films. The film only senses the change in stress, and the minimum response frequency can reach 0.1Hz. Product Features Piezoelectric films are very thin, light, very soft, and can work passively, so they can be widely used in medical sensors, especially when subtle signals need to be detected. Obviously, the material's characteristics are particularly prominent in situations where power supply is limited (in some structures, it can even generate a small amount of energy). Moreover, piezoelectric film is extremely durable and can withstand millions of bending and vibrations. Application contact sensors use the dynamic strain gauge characteristics of piezoelectric film, which can be easily fixed directly on the human skin (such as the inside of the wrist).

[0032] Among them, the preferred method is that the product model 1001777 of the US MEAS sensor is a general-purpose sensor with a pressure-sensitive adhesive coated on one side of the sensor. However, this adhesive has not been certified for biocompatibility. In short-term tests, 3M9842 (polyurethane tape) can be fixed on the skin, and then the piezoelectric film sensor can be pasted on the 3M tape. The reason why piezoelectric film can detect both very small physical signals and large-scale activities is that the piezoelectric response of the PVDF film is linear over a large dynamic range (about 14 orders of magnitude). In most cases, as long as the bandwidth can clearly distinguish the target signal from the noise, the small target signal can be collected by the filter. Similar sensors have been used in sleep disorder research to detect chest, leg, eye muscle and skin movements. In addition, the sensor can be used as an indicator of the effect of anesthesia (neuromuscular conduction) by detecting the response of muscles (such as the muscles between the thumb and index finger) to electric shock. The acceleration sensor Minisense100 is a standard product of Precision Electronics. It adopts a cantilever beam design, one end is clamped with a rigid PCB board with connecting pins, and the other end is equipped with a mass block. The mass block allows the sensor to react consistently when it is vibrated. The mass block 'remains still' while the film deforms, resulting in very high voltage sensitivity (approximately 1V / g). Other vital signs sensors are derived from this element, such as smart badges (with built-in RF telemetry) worn by staff or patients. The wearer's signals are periodically collected to determine their location and track their status. The sensor sets the badge to sleep when it senses that the badge has been removed; if the sensor senses movement of any part of the body, muscle tremors, or even pulse vibrations, it will wake up the badge. Auscultation Many electronic stethoscopes use piezoelectric film as the sensor element because it is durable, highly sensitive, and has a wide bandwidth. In this application, the sensor element is usually encapsulated in a traditional metal stethoscope head because the sensor needs to form a 'force' with the body. Once the dynamic pressure signal is converted into an electrical signal, it can be selectively filtered or amplified, played back as an audio signal, used with more complex algorithms to determine the specific condition, or transmitted to a remote base station for further analysis and storage. Sensor Group A composite acoustic sensor can monitor multiple points at the same time.

[0033] Among them, the preferred method is that DeepBreeze uses a sensor group with nearly 100 sensors to collect the sound information of the patient's inhalation and exhalation. The sensor is attached to the skin surface with a vacuum cover. The collected signal is processed and converted into a sound "image", so that the airflow in the trachea and lungs can be imaged like a cartoon. Any foreign matter and abnormal phenomena are clearly visible in these images. This method is more reliable and safer than X-rays. The bed monitoring piezoelectric film and piezoelectric cable can be installed on the mattress to detect the patient's heartbeat, breathing and body movement. HoanaMedicalInc.'s monitoring bed alarm system installs a group of sensors between the mattress and the sheets. When the patient sits or lies on the monitoring bed, the sensor can accurately measure and collect the patient's vital signs through the clothes and sheets. The flexible switch is used to collect static signals, and all the patient's dynamic signals are collected by the piezoelectric film and converted into corresponding electrical signals, which are displayed on the monitor beside the bed. If the patient's heart rate and breathing rate are abnormal, or the patient gets out of bed without authorization, the system can alarm in advance. All this is done by sensors without direct contact with the patient. Infantrust, a baby breathing monitor, has developed a childcare product called Respisense, using PVDF's extreme sensitivity to stress. Clip the monitor to the baby's waist on the diaper to monitor the baby's heartbeat. The piezoelectric film in Respisense is in direct contact with the abdominal skin. If the baby is not detected to be moving within the set time, the vibration buzzer will be activated, gently moving the baby to stimulate its breathing. If the baby still does not respond within a period of time, the alarm will be activated. Respiratory thermoelectric monitoring PVDF is also very sensitive to dynamic changes in temperature (the typical value of a 28μm thick piezoelectric film is 8V / oC).

[0034] Among them, the preferred method is that the British C-Lect Medical Company has developed a monitor to monitor breathing rate. A small piece of piezoelectric film element is fixed to the mouth and nose with a mask, and the temperature changes of the inhaled and exhaled gases produce a strong electrical signal. Even if heated oxygen / air is inhaled, the measurement results are still very accurate. The PIPPA monitor is powered by a battery, and the LCD displays the number of breaths per minute. Lip contact sensors made of piezoelectric film use the same principle to detect airflow through the mouth or nose. Compared with thermistors, piezoelectric films are highly sensitive, fast in response, soft, and have a large detection area.

[0035] Among them, the preferred method is the working principle of the thin film pressure sensor. The thin film pressure sensor is a resistive sensor based on the multimeter method. Its principle is to utilize the elastic deformation property of the thin film. When the external force acts on the thin film, it causes its elastic deformation, which will cause the resistance value to change. Therefore, a current is introduced between the two electrodes of the sensor. When the film is deformed, the resistance value changes. The pressure on the object being measured is deduced by measuring the change in resistance value.

[0036] Among them, the preferred method is that the structural features of the thin film pressure sensor are generally composed of three parts: a measuring film, a supporting film and a bridge circuit. The measuring film is the contact surface between the object to be measured and the sensor, and the supporting film plays the role of supporting the measuring film. The bridge circuit is used to measure the change in the film resistance value.

[0037] Among them, the preferred method is that the thin film pressure sensor has the following characteristics: 1. High measurement accuracy: Due to the elastic deformation characteristics of the film, the film pressure sensor can achieve high-precision pressure measurement; 2. Simple structure: Due to the simple structure of the film pressure sensor, the production cost is also low; 3. Long life: The life of the film pressure sensor can reach about 10 years; 4. Fast response speed: The response time of the thin film pressure sensor is a few milliseconds, which has a faster response speed.

[0038] Among them, the preferred method is the application of thin film pressure sensors, which can be widely used in the fields of industry, medical treatment, automobiles, etc. The specific applications are as follows: 1. Industrial field: Thin film pressure sensors can be used to measure the pressure, flow, liquid level and other parameters of mechanical equipment, which plays an important role in the operation and maintenance of mechanical equipment; 2. Medical field: Thin film pressure sensors can be used to monitor cardiopulmonary resuscitation of patients using air bags, and can also be used to monitor the injection pressure during intravenous injection; 3. Automobile field: Thin film pressure sensors can be used to detect parameters such as automobile tire pressure and engine pressure.

[0039] Among them, the preferred method is that the thin film pressure sensor is a common type of sensor, which has the characteristics of simple structure, high measurement accuracy, long life, fast response speed, etc., so it has been widely used in the fields of industry, medicine and automobile. For occasions where parameters such as pressure and flow need to be measured, the thin film pressure sensor is a good choice.
