[0102] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0103] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0104] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. Similarly, "including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0105] As used herein, "parallel" and "perpendicular" include the described situation and the situation similar to the described situation, and the range of the similar situation is within the acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement in question and the error associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°.

[0106] It will be understood that when a layer or an element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present between the layer or element and the other layer or substrate.

[0107] Exemplary embodiments are described herein with reference to cross-sectional views and / or plan views that are idealized exemplary drawings. In the drawings, the thickness of layers and regions are exaggerated for clarity. Therefore, variations in shape relative to the drawings due to, for example, manufacturing techniques and / or tolerances are conceivable. Therefore, the exemplary embodiments should not be interpreted as being limited to the shapes of the regions shown herein, but include deviations in shape due to, for example, manufacturing. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the actual shapes of regions of the device, and are not intended to limit the scope of the exemplary embodiments.

[0108] At present, with the improvement of living standards and the acceleration of the pace of life, cardiovascular and cerebrovascular diseases are major diseases that threaten people's health, taking the lives of millions of people every year. Timely and continuous measurement of blood pressure not only helps prevent hypertension, but also helps hypertensive patients control their blood pressure and maintain their health.

[0109] Blood pressure measurement mainly includes two methods: invasive testing and non-invasive testing. Invasive testing is the most direct and the measurement results are more accurate, but it is not suitable for consumers to test themselves and monitor for a long time. Generally, it can only be performed by professional doctors in hospitals. Although non-invasive testing will have certain deviations, it is more convenient to operate, such as the Korotkoff sound method, oscillometric method and pulse method.

[0110] The Korotkoff sound method is mainly to block the blood flow by inflating the cuff, and then slowly deflate it. The tester uses a stethoscope to hear the pulse sound. The sound just appears corresponds to the systolic pressure, and the diastolic pressure is calculated by continuing to deflate until the sound disappears. This method is simple, but it may cause human deviation due to the operator's visual and auditory problems, and it is not suitable for continuous measurement.

[0111] The principle of the oscillometric method is to use the oscillometric principle of the pulse shape to estimate blood pressure based on the relationship between pulse amplitude and cuff pressure. The mean pressure corresponds to the maximum pulse value, and the systolic and diastolic pressures are determined based on the ratio of the corresponding maximum pulse amplitude. Many electronic blood pressure monitors use this method, which has a slightly larger deviation.

[0112] The above two types of blood pressure measurement require a cuff, a stethoscope or an oscilloscope, which involve more equipment and are not very convenient to operate, and are not suitable for continuous blood pressure measurement and monitoring.

[0113] The pulse is formed by the heartbeat propagating along the arteries and blood flow to the periphery. As the blood circulates in the blood vessels, there are slight deviations at different locations. Based on the correlation between the pulse and blood flow, the blood pressure can be indirectly measured through the pulse. This method uses multi-point measurement instead of single-point measurement, and uses the inherent connection and change law between the points near the systolic and diastolic pressure points. It uses the approximation and fitting calculation methods to calculate the true systolic and diastolic pressure values, realize continuous measurement of discontinuous events, and measure relatively accurate blood pressure values.

[0114] At present, pulse blood pressure measurement devices generally require cuff inflation, which is not suitable for long-term blood pressure monitoring. For patients with cardiovascular and cerebrovascular diseases, hypertension and other diseases, it is best to be able to monitor for a long time so that relatives and friends can be reminded in time in critical moments to ensure timely treatment.

[0115] In addition, existing measurement devices have unstable and unreliable test quality when blood pressure is not monitored using a cuff.

[0116] In order to at least alleviate or solve one of the above-mentioned technical problems, the present disclosure provides a blood pressure measuring device.

[0117] Figure 1A A side view of a blood pressure measurement device in some embodiments of the present disclosure. Figure 1B Another side view of the blood pressure measurement device in some embodiments of the present disclosure. Figure 1CIt is a schematic diagram of the planar structure of a blood pressure measuring device in some embodiments of the present disclosure. Figure 2A is an exploded diagram of a blood pressure measurement device in some embodiments of the present disclosure. Figure 2B Schematic diagram of the cross-sectional structure of a blood pressure measuring device in some embodiments of the present disclosure.

[0118] In some embodiments, Figure 1A , Figure 1B , Figure 2A and Figure 2B As shown, a blood pressure measuring device disclosed in the present invention comprises: a housing 100, a signal processor, a plurality of ECG electrodes and a pulse sensor assembly 200. Figure 1A , Figure 1B , Figure 1C , Figure 2A and Figure 2B In the illustrated embodiment, the plurality of ECG electrodes include a first ECG electrode 2 and a second ECG electrode 14 .

[0119] Furthermore, the housing 100 has a storage space inside, and the signal processor is located in the storage space. At least part of the ECG electrodes are located outside the housing 100, and are used to collect ECG signals of the human body. Furthermore, multiple ECG electrodes can collect ECG signals of different parts of the human body.

[0120] At least part of the pulse sensor assembly 200 is located outside the housing 100 and is used to collect a pulse signal of a human body.

[0121] The ECG electrodes and the pulse sensor assembly 200 are electrically connected to the signal processor respectively, and the signal processor is configured to determine the blood pressure value according to the pulse signal and the ECG signal.

[0122] The disclosed embodiment collects ECG signals from different positions of the human body through multiple ECG electrodes, collects the human body's pulse signal through a pulse sensor assembly, and further calculates the human body's blood pressure based on the ECG signals and pulse signals through a signal processor, thereby achieving measurement of the human body's blood pressure.

[0123] In the embodiment of the present disclosure, the number and specific positions of the ECG electrodes can be set according to actual needs, and the embodiment of the present disclosure is not limited to this.

[0124] Specifically, in 1A, Figure 1B , Figure 2A and Figure 2BIn the illustrated embodiment, the first ECG electrode 2 is located on one side of the housing 100, and the first ECG electrode 2 is used to collect a first ECG signal at a finger of a human body. The second ECG electrode 14 is located on a side of the housing 100 away from the first ECG electrode 2, and is used to collect a second ECG signal at a wrist of a human body. At least a portion of the pulse sensor assembly 200 is located on a side of the housing 100 away from the first ECG electrode 2, and is used to collect a pulse signal at a wrist of a human body.

[0125] The housing 100 is provided with openings, wherein the first ECG electrode 2, the second ECG electrode 14 and the pulse sensor assembly 200 are electrically connected to the signal processor through the openings respectively.

[0126] The signal processor is configured to determine a blood pressure value according to the pulse signal, the first electrocardiogram signal and the second electrocardiogram signal.

[0127] During use of the blood pressure measurement device provided in the embodiment of the present disclosure, the second ECG electrode 14 and the pulse sensor assembly 200 can be attached to the inner side of the wrist, the pulse sensor assembly 200 collects the pulse signal, the second ECG electrode 14 collects the second ECG signal at the wrist, and at the same time, the finger presses the first ECG electrode 2, the first ECG electrode 2 collects the first ECG signal at the finger, and the signal processor calculates the blood pressure value based on the collected signal and the pulse signal, thereby realizing blood pressure detection. For example, the PWTT method is used to measure blood pressure. PWTT refers to the time difference between the peak of the electrocardiogram (ECG) wave and the inflection point of the pulse wave (Peripheraw Pulse Wave). Generally speaking, the PWTT method is to use this time difference and then directly calculate the patient's blood pressure value based on the sample data in the database. For example, a blood pressure calculation model can be constructed based on the sample data in the database, and the blood pressure value can be obtained by inputting the time difference into the blood pressure calculation model.

[0128] The embodiment of the present disclosure respectively sets a first ECG electrode 2 and a second ECG electrode 14 for collecting ECG signals on opposite sides of the housing 100, and collects ECG signals at different positions, which can ensure the accuracy of ECG signal collection.

[0130] In the disclosed embodiment, a plurality of conductive protrusions 14-1 are provided on the surface of the second ECG electrode 14 away from the housing 100 to increase the contact area between the second ECG electrode 14 and the wrist skin, thereby ensuring that the second ECG electrode 14 collects ECG signals at the wrist. At the same time, the plurality of conductive protrusions 14-1 can also prevent the second ECG electrode 14 from directly contacting the wrist skin over a large area, causing sweating and affecting the accuracy of the collected signals.

[0131] In some embodiments, Figure 2A and Figure 2B As shown, the housing 100 includes a first housing portion 3 and a second housing portion 9 that are oppositely disposed and connected, and the first housing portion 3 and the second housing portion 9 define a receiving space.

[0137] The disclosed embodiment fixes the sensor 11 on the fixing frame 10, so as to facilitate adjustment of the position of the sensor 11 to achieve contact between the sensor 11 and the wrist skin, thereby ensuring the accuracy of the pulse signal.

[0138] In addition, at least part of the sensor 11 is located outside the housing. Figure 2B As shown, the sensor 11 is located outside the housing 100. In another example, a portion of the sensor 11 is located outside the housing 100, and another portion is located in the accommodation space.

[0143] The sensing portion 112 is disposed on a side of the base 111 away from the fixing frame 10 and is electrically connected to the first connecting member, specifically, to the sensor connecting terminal 11 - 1 .

[0144] In the disclosed embodiment, the sensing unit 112 is fixed to the fixing frame 10 via the base 111 , so as to facilitate the installation of the sensing unit 112 .

[0145] In some embodiments, Figure 2A and Figure 2B As shown, the pulse sensor assembly 200 further includes a protective film 12 disposed on a side of the sensor 11 away from the fixing frame 10 .

[0146] In the disclosed embodiment, disposing a protective film 12 on a side of the sensor 11 away from the fixing frame 10 can prevent the sensor 11 from being worn and increase the service life.

[0147] Optionally, the material of the protective film 12 may include a soft-glue material. Selecting a soft-glue material to prepare the protective film 12 can make the protective film 12 have greater elasticity and recoverability, which can not only better transmit the pulse pressure, but also protect the sensing part 112.

[0148] In some embodiments, Figure 2A As shown, a plurality of positioning posts 9-3 are arranged on the inner wall of the housing 100. Specifically, for example, the positioning posts 9-3 are arranged on the side of the second housing portion 9 facing the first housing portion 3. The fixing frame 10 is provided with first positioning holes 10-3, which correspond one to one with the positioning posts 9-3.

[0149] like Figure 3B As shown, the pulse sensor assembly 200 also includes a protective film mounting portion 24 fixedly connected to the edge of the protective film 12, and a second positioning hole 24-1 is opened on the protective film mounting portion 24, and the second positioning hole 24-1 corresponds to the positioning column 9-3 one by one.

[0150] The positioning column 9-3 passes through the second positioning hole 24-1 and the first positioning hole 10-3. The protective film installation portion 24 is located between the fixing frame 10 and the housing 100, specifically between the fixing frame 10 and the second housing portion 9. The protective film 12 passes through the first opening 9-8.

[0151] like Figure 2A As shown, the housing 100 is further provided with a first buckle 9-5 and a second buckle 9-6, wherein the first buckle 9-5 and the second buckle 9-6 are specifically provided on a side of the second housing portion 9 facing the first housing portion 3 and are located on opposite sides of the first opening 9-8. The first buckle 9-5 and the second buckle 9-6 are used to fix the fixing frame 10 on the housing 100, that is, fixed on the second housing portion 9.

[0152] In the disclosed embodiment, the protective film mounting portion 24 and the fixing frame 10 can be initially positioned by the positioning column 9-3 on the housing, the second positioning hole 24-1 on the protective film mounting portion 24, and the first positioning hole 10-3 on the fixing frame 10. Then, the fixing frame 10 is restricted to the side of the second housing portion 9 facing the first housing portion 3 by the first buckle 9-5 and the second buckle 9-6, and at the same time, the protective film mounting portion 24 is restricted between the fixing frame 10 and the second housing portion 9, thereby achieving the installation of the fixing frame 10 and the protective film mounting portion 24.

[0153] It can be understood that the protective film installation part 24 and the fixing frame 10 are both clamped between the second housing part 9 and the buckle (the first buckle 9-5, the second buckle 9-6). Furthermore, the spacing between the second housing part 9 and the buckle can be designed to be smaller than the sum of the thicknesses of the protective film installation part 24 and the fixing frame 10, so that an interference fit can be achieved, ensuring that the protective film installation part 24 can be closely attached to the inner side of the second housing part 9, and the joint of the protective film installation part 24 and the second housing part 9 can form a sealing structure, thereby ensuring that liquid does not enter the accommodation space from the joint of the protective film installation part 24 and the second housing part 9.

[0154] In addition, it can be understood that the protective film 12 can form a receiving groove facing the receiving space, and the sensor 11 is located in the receiving groove.

[0155] Specifically, in one example, Figure 3C As shown, the length L of the protective film 12 is 21 mm. The length L of the protective film 12 refers to the dimension in the extension direction of the housing.

[0156] like Figure 3D As shown, the thickness H of the protective film 12 is 3.6 mm.

[0157] It should be noted that the thickness of the protective film 12 does not refer to the thickness of the protective film 12 itself, but refers to the size of the outside of the accommodating groove in the thickness direction of the shell.

[0158] like Figure 3C and Figure 3D As shown, the width W of the protective film 12 is 11.6 mm. The width W of the protective film 12 is the dimension of the protective film 12 in the width direction of the housing.

Figure 4B It is another partial structural schematic diagram of the blood pressure measurement device in some embodiments of the present disclosure.

[0166] In some embodiments, Figure 4A and Figure 4B As shown, the blood pressure measuring device further includes: a display screen 25.

[0168] In the disclosed embodiment, after the digital circuit board 18 calculates the blood pressure value, the blood pressure can be displayed on the display screen 25, so that the user can read the blood pressure value information.

[0169] Furthermore, if Figure 2A and Figure 2B As shown, the blood pressure measuring device further includes a cover plate 1.

Specifically, the first sealing member is arranged between the first housing portion 3 and the cover plate 1.

[0170] In one example, the first sealing member may be a sealant, which is bonded to the cover plate 1 and the first housing portion 3 respectively, thereby achieving sealing. Figure 2A As shown, a third sealing groove 3-10 surrounding the light-transmitting window 3-8 can be formed on the carrier plate 32, and then a sealant is applied in the third sealing groove 3-10, and the edge of the cover plate 1 is bonded to the sealant, and after the sealant solidifies, it becomes the first sealing member.

[0171] The first seal in the embodiment of the present disclosure can prevent a gap from existing between the housing 100 and the cover plate 1 , thereby further preventing liquid from entering the housing.

The mounting ring 412 is used to connect the blood pressure measurement device to an external wearable object, such as the wristband 21.

[0192] Figure 8 It is a schematic diagram of the structure of the buckle assembly in some embodiments of the present disclosure.

[0193] In some embodiments, Figure 2A and Figure 6 As shown, a slide groove 3-2 is also provided on the side wall of the first installation groove 3-1.

The two ends of the first limiting portion 63 are respectively connected to the first mounting column 61 and the second mounting column 62, and there is a gap between the first limiting portion 63 and the force-applying portion 64. Optionally, the two ends of the first limiting portion 63 are fixedly connected to the force-applying portion 64. The gap between the first limiting portion 63 and the force-applying portion 64 can allow the hook 42 to pass through, and the hook 42 passes through the gap between the first limiting portion 63 and the force-applying portion 64 and is engaged with the first limiting portion 63. Furthermore, a protrusion 6-1 is provided on the force-applying portion 64, and the protrusion 6-1 can extend into the slide groove 3-2 and can slide relative to the slide groove 3-2 along the extension direction of the slide groove 3-2. The slide groove 3-2 extends along the depth direction of the first mounting groove 3-1.

[0194] The first mounting column 61 and the second mounting column 62 are both sleeved with an elastic member 5, and when at least a portion of the first mounting column 61 and at least a portion of the second mounting column 62 are located in the first mounting groove 3-1 and the force-applying portion 64 is not subjected to an external force, the elastic member 5 is in a compressed state, and the hook 42 can be engaged with the first position-limiting portion 63. When the force-applying portion 64 is pressed along the depth direction of the first mounting groove 3-1, the first position-limiting portion 63 can be separated from the hook 42.

[0195] The disclosed embodiment can move the first limiting portion 63 by pressing the force-applying portion 64, thereby separating from the hook 42, thereby realizing the removal of the wristband mounting portion 4; and when not pressed, the elastic member 5 applies an elastic force toward the second housing portion to the first limiting portion 63, thereby making the hook 42 hook on the first limiting portion 63, thereby realizing the fixed connection between the wristband mounting portion 4 and the housing. In addition, the cooperation between the protrusion 6-1 and the slide groove 3-2 can prevent the buckle assembly 6 from being completely pushed out of the first mounting groove 3-1 by the elastic member 5 when the wristband mounting portion 4 is not installed.

[0196] Fig. 9 It is another partial structural schematic diagram of the blood pressure measurement device in some embodiments of the present disclosure.

Specifically, the rechargeable battery 7 is electrically connected to the digital circuit board 18. The charging assembly is arranged in the accommodation space and is electrically connected to the signal processor. The charging end of the charging assembly is exposed by the charging port 9-2. The charging assembly is used to receive the electrical signal provided by the external power supply and transmit the electrical signal to the signal processor.

[0198] The signal processor is further configured to perform voltage conversion on the electrical signal and transmit the converted electrical signal to the rechargeable battery 7 .

[0199] Fig.10 It is another partial structural schematic diagram of the blood pressure measurement device in some embodiments of the present disclosure.

[0200] In some embodiments, Fig.10 As shown, the charging assembly includes at least two charging spring pins 16. One end of the charging spring pin 16 is exposed by the charging port 9-2. Obviously, this end of the charging spring pin 16 is the charging end. The other end of the charging spring pin 16 is electrically connected to the signal processor, and the charging spring pin is in a compressed state. Specifically, the other end of the charging spring pin 16 is electrically connected to the digital circuit board 18, and the digital circuit board 18 is configured to perform voltage conversion on the electrical signal of the external power supply and transmit the converted electrical signal to the rechargeable battery 7.

[0201] Alternatively, if Figure 5 As shown, the analog circuit board 8 is provided with a avoidance hole 8-4 corresponding to the charging spring pin 16. The charging spring pin 16 passes through the avoidance hole 8-4 and is electrically connected to the digital circuit board 18.

[0202] Alternatively, if Fig.10As shown, the charging spring needle 16 includes a first charging part 161 and a second charging part 162. Among them, one end of the first charging part 161 extends into the charging port 9-2 and is exposed by the charging port 9-2, and is used to contact and electrically connect with an external power source. The other end of the first charging part 161 is electrically connected to one end of the second charging part 162, and the second charging part 162 can move relative to the first charging part 161 in a direction away from or close to the first charging part 161. For example, the first charging part 161 has a receiving groove at one end close to the second charging part 162, one end of the second charging part 162 is located in the receiving groove, and the depth of the second charging part 162 in the receiving groove can be adjusted. When the charging spring needle is in a compressed state, the depth of the second charging part 162 in the receiving groove is deeper. The other end of the second charging part 162 is electrically connected to the digital circuit board 18.

[0203] In the disclosed embodiment, the charging spring pin 16 is in a compressed state, which can ensure the electrical connection between the charging spring pin 16 and the digital circuit board 18 .

[0204] In some embodiments, a second sealing member surrounding the charging spring pin 16 is disposed on the inner wall of the housing 100. The second sealing member is used to seal the gap between the charging spring pin 16 and the housing 100.

[0205] Specifically, the second sealing member is disposed between the second housing portion 9 and the charging spring pin 16. For example, the second sealing member may be a sealant, and the sealant is bonded to the second housing portion 9 and the charging spring pin 16, respectively, so as to achieve sealing between the second housing portion 9 and the charging spring pin 16, and prevent the gap between the second housing portion 9 and the charging spring pin 16 from causing liquid to enter the accommodation space.

[0206] In one example, if Fig.10 As shown, a groove 9-11 surrounding the charging port 9-2 is provided on the inner side of the second housing portion 9. It is understandable that after the charging spring pin 16 is installed at the charging port 9-2, the groove 9-11 surrounds the charging spring pin 16, for example, the groove 9-11 specifically surrounds the first charging portion 161. The groove 9-11 is filled with sealant, and the second sealant can be formed after the sealant solidifies.

[0207] In some embodiments, Fig.10 As shown, the charging assembly further includes a magnet 15, and optionally, the magnet 15 is located between two adjacent charging spring pins 16.

[0208] Fig.11 It is a structural schematic diagram of the charging process of the blood pressure measurement device in some embodiments of the present disclosure.

[0209] like Fig.11As shown, the charging spring pin 16 and the charging head 22 can perform magnetic charging.

[0210] Fig.12 It is a schematic diagram of the assembly structure of a blood pressure measurement device in some embodiments of the present disclosure.

[0211] In some embodiments, Fig.12 As shown, the first housing portion 3 includes: a first portion 301 and a second portion 302 connected to the first portion 301. For example, the boundary between the first portion 301 and the second portion 302 is located at the position of the dotted line a. The second housing portion 9 includes: a third portion 901 opposite to the first portion 301 and a fourth portion 902 opposite to the second portion 302. For example, the boundary between the third portion 901 and the fourth portion 902 is located at the position of the dotted line b. Among them, the thickness direction of the first portion 301 intersects with the thickness direction of the second portion 302, and the thickness direction of the third portion 901 intersects with the thickness direction of the fourth portion 902.

[0212] Furthermore, the first ECG electrode 2 is disposed opposite to the first portion 301 , the second ECG electrode 14 is disposed opposite to the third portion 901 , and the pulse sensor assembly 200 is disposed opposite to the fourth portion 902 .

[0213] In the embodiment of the present disclosure, the first part and the second part connected to the first part form an angle, and the angle is set to be relatively large, for example, it can be an obtuse angle. The purpose is to achieve contact between the shell 100 and the wrist, thereby ensuring the contact between the second ECG electrode 14 and the pulse sensor assembly 200 and the wrist skin, and ultimately ensuring that the ECG signal and pulse signal can be accurately measured.

[0214] In some embodiments, Figure 2A As shown, the housing 100 is also provided with a power button hole 3-3. For example, the power button hole 3-3 is specifically provided on the first housing portion 3. The blood pressure measuring device further includes a power button 19, which corresponds to the power button hole 3-3 and is located in the power button hole 3-3, and a portion of the power button 19 is located outside the housing 100 for easy pressing. The signal processor is provided with a switch 18-3, for example, the switch 18-3 is specifically provided on the digital circuit board 18. When the power button 19 is pressed, the power button 19 can contact the switch 18-3 and apply force to the switch 18-3 to start the blood pressure measuring device.

[0215] Fig.13A : is a schematic diagram of the three-dimensional structure of the power button in some embodiments of the present disclosure. Fig.13A (a) and (b) are schematic diagrams of the three-dimensional structure at two angles respectively. Fig. 13B It is a partial cross-sectional structural schematic diagram of a blood pressure measurement device in some embodiments of the present disclosure.

[0216] In some embodiments, Fig.13A and Fig. 13B As shown, the power button 19 includes a flexible button portion 192 and a rigid button portion 191. A portion of the flexible button portion 192 is connected to the inner side of the housing 100, for example, in combination with Figure 2A As shown, the flexible button portion 192 can be fixedly connected to the inner side of the first housing portion 3. The rigid button portion 191 is connected to another part of the flexible button portion 192 and passes through the power button hole 3-3. The hardness of the rigid button portion 191 is greater than that of the flexible button portion 192, or the elasticity of the flexible button portion 192 is greater than that of the rigid button portion 191.

[0217] For example, the material of the flexible button portion 192 may be a soft silicone material, and the material of the rigid button portion 191 may be a hard plastic part.

[0218] In the disclosed embodiment, the rigid button portion 191 passes through the power button hole 3-3, so the user can press the rigid button portion 191. Further, under the pressure of the rigid button portion 191, the flexible button portion 192 can be deformed, thereby contacting the switch 18-3 on the digital circuit board 18, thereby starting the blood pressure measurement device. Furthermore, a part of the flexible button portion 192 is closed and connected to the inner side of the first housing portion 3. For example, the flexible button portion 192 and the first housing portion 3 are fixed by bonding with a sealant, thereby achieving closure and preventing liquid from entering the accommodation space.

[0219] In some embodiments, Fig. 13B As shown, the flexible button portion 192 is provided with a through hole 19-1 opposite to the power button hole 3-3. The rigid button portion 191 includes a first sub-portion 1911, a second sub-portion 1912 and a third sub-portion 1913 connected in sequence, wherein the second sub-portion 1912 is located in the through hole 19-1, the first sub-portion 1911 and the third sub-portion 1913 are located on opposite sides of the through hole 19-1 in its extension direction, and the size of the first sub-portion 1911 and the size of the third sub-portion 1913 are both larger than the aperture of the through hole 19-1. It can be understood that the size of the first sub-portion 1911 and the size of the third sub-portion 1913 are both larger than the aperture of the through hole 19-1, which means that the first sub-portion 1911 and the third sub-portion 1913 cannot extend into or pass through the through hole 19-1.

[0220] In the disclosed embodiment, the second sub-portion 1912 is filled in the through hole 19-1, and the first sub-portion 1911 and the third sub-portion 1913 cannot extend into or pass through the through hole 19-1, so that the through hole 19-1 is sealed while ensuring the connection between the rigid button portion 191 and the flexible button portion 192, thereby preventing liquid from entering the power button 19 through the through hole 19-1. Furthermore, the first sub-portion 1911 and the flexible button portion 192, as well as the third sub-portion 1913 and the flexible button portion 192, can be bonded and fixed with sealant, thereby improving the sealing of the power button 19.

[0223] In one example, the third sealing member may be a sealant, which is bonded to the first ECG electrode 2 and the first housing portion 3, respectively, so as to achieve sealing. Figure 2A As shown, a second sealing groove 3-11 is formed on the bearing plate 32 of the first housing portion 3, and the second sealing groove 3-11 surrounds the second opening 3-7. Then, a sealant is applied to the second sealing groove 3-11, and the edge of the first ECG electrode 2 is bonded to the sealant, and the third sealant is formed after the sealant solidifies. The embodiment of the present disclosure can avoid the existence of a gap between the first housing portion 3 and the first ECG electrode 2 by setting a third sealant, thereby further preventing liquid from entering the accommodation space.
