Description

Technical Field

[0001] The utility model belongs to the technical field of health monitoring, and in particular relates to a pulse wave detection device and a wearable health monitoring device. Background Art

[0002] Most current pulse wave detection devices use photoplethysmography (PPG) to measure the attenuated light reflected and absorbed by human blood vessels and tissues, thereby recording the pulsation state of blood vessels and completing pulse wave measurement. However, in actual use, the PPG mode has been found to be susceptible to unavoidable factors such as skin, environment, and blood flow, resulting in poor detection accuracy.

[0003] Contact-type pulse wave detection devices can avoid the influence of these factors. However, if the flexible sensor in the pulse wave detection device is in direct contact with human skin, the flexible sensor is easily damaged by friction between the flexible sensor and the human skin. Or, the flexible sensor cannot be reset in time to maintain good contact with the human skin, resulting in reduced pulse wave detection accuracy and poor physical condition monitoring effect.

[0030] Reference below Figures 1 to 5 The present invention provides a pulse wave detection device and a wearable health monitoring device.

[0031] like Figures 1 to 5As shown, the pulse wave detection device according to the first embodiment of the present invention can be used to detect human pulses, allowing people to understand their health status in real time. This embodiment effectively protects the flexible sensor 300, preventing it from wearing out due to friction between the flexible sensor 300 and the human skin. It also ensures that the flexible sensor 300 always maintains good contact with the human skin, ultimately improving the pulse wave detection accuracy of the pulse wave detection device.

[0032] The structure of the pulse wave detection device includes a detection device body, an elastic protection layer 410 and an elastic reset layer 420 .

[0033] The detection device comprises a housing 200 and a flexible sensor 300. The housing 200 provides a mounting location for the flexible sensor 300. The flexible sensor 300 is configured to detect pulse waves and generate detection signals. Furthermore, the flexible sensor 300 includes a flexible detection portion 310 having a flat detection surface facing the human skin, allowing the pulse signal to be transmitted to the flexible detection portion 310 via the detection surface.

[0034] In this embodiment, the flexible sensor 300 is a flexible film sensor. Specifically, the flexible sensor 300 can be a PVDF (polyvinylidene fluoride) piezoelectric film sensor. The piezoelectric film of the PVDF piezoelectric film sensor is flexible and lightweight, similar to human skin, and has good impedance coupling with human tissue. Therefore, the piezoelectric film of the PVDF piezoelectric film sensor can closely adhere to human skin, allowing the piezoelectric film to cover the pulse wave collection position on the wrist, thereby ensuring that the pulse detection signal is effectively collected by the piezoelectric film without distortion.

[0035] The elastic protective layer 410 is located on one side of the flexible detection portion 310 in its own thickness direction. The elastic protective layer 410 covers the detection surface of the flexible detection portion 310, and the elastic protective layer 410 and the flexible detection portion 310 are in a non-fixed connection. Specifically, the elastic protective layer 410 and the detection surface of the flexible detection portion 310 are in close contact, that is, the contact surface between the elastic protective layer 410 and the flexible detection portion 310 is in non-fixed contact. Then, the two relative contact surfaces between the elastic protective layer 410 and the flexible detection portion 310 can slide relative to each other, which can reduce the in-plane stress on the components of the flexible sensor 300 caused by friction with the skin and avoid damage to the components of the flexible sensor 300. The elastic protective layer 410 can be connected to the shell 200.

[0036] The elastic protective layer 410 can be made of an elastically deformable material such as silicone. In this embodiment, the elastic protective layer 410 is a silicone layer. The thickness of the elastic protective layer 410 is less than or equal to 3 mm. If the thickness of the elastic protective layer 410 is too thin, the elastic protective layer 410 will not effectively protect the flexible detection portion 310. If the thickness of the elastic protective layer 410 is too thick, the pulse wave transmission effect will be poor, affecting the detection function of the flexible sensor 300.

[0037] It can be understood that when monitoring human pulse, the elastic protective layer 410 will directly contact the human skin. The elastic protective layer 410 is located between the human skin and the detection surface of the flexible detection part 310. The elastic protective layer 410 can separate the human skin and the flexible detection part 310. The elastic protective layer 410 provides good protection for the flexible detection part 310, avoiding the problem that the flexible detection part 310 is easily worn out too quickly due to the friction between the flexible detection part 310 and the human skin due to direct contact with the human skin, or causing the flexible detection part 310 to be easily damaged due to the friction moving with the human skin, thereby ensuring that the flexible sensor 300 can stably and effectively collect human pulse wave signals for a long time.

[0038] Furthermore, since the elastic protective layer 410 has a certain degree of deformation ability, during the beating of the human pulse, the elastic protective layer 410 can deform accordingly with the beating of the human pulse, thereby enabling the human pulse wave signal to be effectively transmitted to the flexible detection portion 310 through the elastic protective layer 410, allowing the flexible sensor 300 to generate a detection signal.

[0039] The elastic reset layer 420 is provided on the housing 200. The elastic reset layer 420 is located on the other side of the flexible detection part 310 in its own thickness direction. The flexible detection part 310 is located between the elastic reset layer 420 and the elastic protective layer 410. In addition, the elastic reset layer 420 and the flexible detection part 310 are non-fixedly connected. Specifically, the contact surface between the elastic reset layer 420 and the flexible detection part 310 is in contact and non-fixed contact. The elastic reset layer 420 can be made of a material that can be elastically deformed, such as silicone. In this embodiment, the elastic reset layer 420 is a silicone layer. The elastic reset layer 420 covers the surface of the flexible detection part 310 opposite to the detection surface. The elastic reset layer 420 is connected to the housing 200.

[0040] It is understood that the thickness of the elastic reset layer 420 and the elastic protective layer 410 can be set according to actual conditions and are not specifically limited here. When the flexible detection portion 310 of the flexible sensor 300 is installed, the elastic reset layer 420 is set between the flexible detection portion 310 and the housing 200. The elastic reset layer 420 plays a good reset role for the flexible detection portion 310. When the human pulse beats, the flexible detection portion 310 will move along its own thickness direction with the human pulse. At this time, the elastic force of the elastic reset layer 420 can be used to prompt the flexible detection portion 310 to quickly reset and adhere to the human skin, so that the flexible sensor 300 can stably and effectively collect the human pulse wave signal, thereby avoiding the problem that the flexible detection portion 310 cannot be reset and separates from the human skin during the human pulse, resulting in a decrease in detection accuracy.

[0041] In the pulse wave detection device provided by the embodiment of the first aspect of the present invention, since the flexible detection portion 310 of the flexible sensor 300 is in contact with the elastic reset layer 420 on the housing 200, and the elastic protective layer 410 is covered on the detection surface of the flexible detection portion 310, during the use of the pulse wave detection device, the elastic protective layer 410 separates the human skin and the flexible detection portion 310, allowing the elastic protective layer 410 to withstand the friction exerted by the human skin, thereby avoiding excessive wear of the flexible detection portion 310 and resulting in a decrease in detection accuracy. , or even the detection function fails, which well protects the flexible sensor 300. At the same time, the elastic deformation of the elastic protective layer 410 can be used to allow the pulse wave signal to be transmitted to the flexible detection part 310 through the elastic protective layer 410, which can ensure that the measured signal is not shielded and ensure that the flexible sensor 300 can generate a detection signal; and the elastic force of the elastic reset layer 420 can be used to prompt the flexible detection part 310 to reset during the human pulse beating process, ensuring that the flexible detection part 310 always maintains good contact with the human skin, thereby improving the detection accuracy.

[0042] In this embodiment, if Figures 1 to 3 As shown, the housing 200 is hollowed out to form a mounting cavity 230. The opening of the mounting cavity 230 is open to one side in the thickness direction of the detection device body. The opening of the mounting cavity 230 is configured as a detection port 210. The detection port 210 is located on the bottom surface of the detection device body and can correspond to the pulse detection position of a person, so that the flexible sensor 300 can effectively collect the pulse wave detection signal. The flexible sensor 300 is disposed in the mounting cavity 230 of the housing 200, and the flexible detection portion 310 is disposed corresponding to the opening of the mounting cavity 230.

[0043] The elastic protective layer 410 is located outside the mounting cavity 230 of the housing 200, and the elastic reset layer 420 is disposed within the mounting cavity 230 of the housing 200 and is fixedly connected to the housing 200. Specifically, a support 240 is disposed within the mounting cavity 230 and is detachably connected to the housing 200. One surface of the elastic reset layer 420 is fixedly connected to the support 240, and the other surface of the elastic reset layer 420 is in contact with the surface of the flexible detection portion 310 that is adjacent to the support 240.

[0044] It is understandable that the detection surface of the flexible detection portion 310 can be located outside or inside the mounting cavity 230 of the housing 200. Of course, the detection surface of the flexible detection portion 310 can be flush with the bottom surface of the detection device body.

[0045] In this embodiment, the flexible detection portion 310, the elastic protective layer 410, and the elastic return layer 420 are all square in shape, viewed along the thickness of the flexible detection portion 310. The mounting cavity 230 is a square cavity. A certain gap exists between the flexible detection portion 310 and the inner wall of the mounting cavity 230. In other words, the sidewalls of the flexible detection portion 310 do not contact the inner wall of the mounting cavity 230.

[0046] In a specific embodiment, Figures 1 to 4 As shown, the detection device body also includes a monitoring body 100. The monitoring body 100 is connected to the housing 200. It is understood that the connection between the monitoring body 100 and the housing 200 can be fixed or hinged. The monitoring body 100 is electrically connected to the flexible sensor 300 via a circuit, and the monitoring body 100 is capable of receiving detection signals transmitted by the flexible sensor 300. Furthermore, the monitoring body 100 is configured to monitor human physiological sign data based on the detection signals from the flexible sensor 300.

[0047] Specifically, the monitoring body 100 comprises a protective shell and a physiological monitoring module 150. The protective shell is connected to the housing 200 and is hollowed out to form a protective cavity 170. The physiological monitoring module 150 is disposed within the protective cavity 170 of the protective shell, providing good protection for the physiological monitoring module 150. Furthermore, the physiological monitoring module 150 is configured to receive and process detection signals from the flexible sensor 300.

[0048] In this embodiment, the flexible sensor 300 includes a flexible detection part 310 and a connecting line 320. The connecting line 320 can be a flat cable. One end of the connecting line 320 is electrically connected to the flexible detection part 310, and the other end of the connecting line 320 is electrically connected to the physiological monitoring module 150. The flexible detection part 310 directly contacts the human skin through the elastic protective layer 410 to complete the collection of the pulse wave detection signal. The connecting line 320 transmits the detection signal generated by the flexible detection part 310 to the physiological monitoring module 150.

[0049] The protective shell is integrally formed with the housing 200. It is understood that the outer shell formed by connecting the protective shell and the housing 200 includes a bottom shell 141 and a top cover 142. The top cover 142 is fixedly connected to the bottom shell 141, so that a mounting cavity 230 and a protective cavity 170 are formed between the top cover 142 and the bottom shell 141. The mounting cavity 230 is connected to the protective cavity 170, so that the connecting line 320 can be electrically connected to the physiological monitoring module 150. The top cover 142 is located above the bottom shell 141 and can be mounted on the bottom shell 141 by screw connection or the like.

[0050] More specifically, Figures 1 to 5 As shown, the physiological monitoring module 150 includes a signal amplification unit, a processing unit and a wireless communication unit.

[0051] Among them, the flexible sensor 300, the signal amplification unit, the processing unit and the wireless communication unit are electrically connected in sequence through lines, and the signal amplification unit is configured to receive the detection signal of the flexible sensor 300 and perform signal amplification processing, the processing unit is configured to perform signal analysis processing on the amplified detection signal, and the wireless communication unit is configured to wirelessly send the analysis result of the processing unit to an external terminal for display.

[0052] It can be understood that since the piezoelectric monitoring signal generated by the flexible sensor 300 is a weak voltage signal, the magnitude of the voltage signal is proportional to the degree of pressure on the flexible sensor 300. Therefore, first, through the signal amplification function of the signal amplification unit, the signal amplification unit converts and amplifies the pulse wave detection signal into voltage data proportional to the external force after receiving the pulse wave detection signal from the flexible sensor 300, and outputs the data to the processing unit; then, with the help of the signal processing function of the processing unit, after receiving the voltage data output by the signal amplification unit, the processing unit converts the amplified voltage data into human pulse data through intelligent algorithm optimization, and outputs the data to the wireless communication unit; finally, using the data remote transmission function of the wireless communication unit, the wireless communication unit transmits the obtained human pulse data to the external smart terminal device through a wireless network, so that people can directly view it at the smart terminal device.

[0053] In addition, if Figure 2 and Figure 3 As shown, the detection device body is provided with a built-in power supply 160. The function of the built-in power supply 160 is to power the physiological monitoring module 150 and the flexible sensor 300 to ensure their normal operation. The built-in power supply 160 can be a battery or a button battery.

[0054] In this embodiment, the built-in power supply 160 is a battery, specifically a lithium battery. The bottom housing 141 is provided with a charging port 110, and the physiological monitoring module 150 is electrically connected to a charging interface 151. The charging interface 151 may be, but is not limited to, a Type-C interface. After the physiological monitoring module 150 is mounted on the bottom housing 141, the charging interface 151 is provided corresponding to the charging port 110, so that the charging cable can be inserted through the charging port 110 into the charging interface 151 to charge the built-in power supply 160.

[0055] In addition, if Figure 1 and Figure 2 As shown, the bottom shell 141 is provided with a through hole, and the physiological monitoring module 150 is electrically connected to a button 120. The number of buttons 120 is not limited to one. After the physiological monitoring module 150 is fixedly connected to the bottom shell 141, the button 120 is arranged corresponding to the through hole, and the button 120 protrudes from the through hole so that people can control the opening and closing of the pulse wave detection device by pressing the button 120 on the physiological monitoring module 150.

[0056] In this embodiment, if Figures 1 to 3 As shown, the detection device body is provided with connecting portions for connecting with accessories on opposite sides of its extension direction. Specifically, the connecting portions are integrally formed with the bottom shell 141. The connecting portion proximal to the flexible sensor 300 is designated as the second connecting portion 220, and the connecting portion proximal to the physiological monitoring module 150 is designated as the first connecting portion 130. Both the first connecting portion 130 and the second connecting portion 220 are provided with axial holes, allowing accessories such as belts or steel belts to be mounted in these axial holes via the connecting shafts. This allows the pulse wave detection device to be worn at a corresponding position on the human body via the accessories, allowing the flexible sensor 300 to acquire pulse wave detection signals.

[0057] like Figures 1 to 5 As shown, the wearable health monitoring device according to the second embodiment of the present invention includes the pulse wave detection device and components of the first embodiment.

[0058] It is understood that the wearable health monitoring device can be an electronic product that can be worn on the human body, such as a wristband, watch, ring, or armband. The fastener can be a belt, steel belt, etc., to firmly fix the pulse wave detection device to a part of the human body, such as the wrist or arm.

[0059] In this embodiment, the wearable health monitoring device is configured as a wristband. Opposite ends of the wristband are fixedly connected to two connecting portions of the pulse wave detection device, respectively, so that the pulse wave detection device can be worn on a person's wrist to reflect the person's physical health by monitoring the person's pulse.

[0060] Since the wearable health monitoring device provided in the embodiment of the second aspect of the present invention adopts all the technical solutions of all the embodiments of the first aspect, the second aspect of the present invention has at least the beneficial effects obtained by the technical solutions of the above embodiments, which will not be repeated here.

[0061] In the wearable health monitoring device provided by the embodiment of the second aspect of the present invention, due to the use of the pulse wave detection device with the above-mentioned unique structure, it is possible to avoid the problem that the flexible sensor 300 is easily worn due to the friction of the human skin, resulting in reduced detection accuracy or even failure of the detection function. It can also ensure that the flexible sensor 300 is always in contact with the human skin during the beating of the human pulse, and continuously and effectively obtains the detection signal of the human pulse, thereby improving the accuracy of the wearable health monitoring device in monitoring people's physical conditions.

[0062] It should be understood that the various parts of the embodiments of the present invention can be implemented using hardware, software, firmware, or a combination thereof. In the above embodiments, multiple steps or methods can be implemented using software or firmware stored in a memory and executed by a suitable instruction execution system.
