[0029] With the improvement of people's living standards and the increasing attention to physical health, more and more families are equipped with various household medical devices to facilitate the simple management of family members' health. Sphygmomanometers have currently become commonly used health monitoring devices in people's daily lives. For the arm-type sphygmomanometers in the related art, for those who need to monitor blood pressure multiple times, they are usually worn for a long time. In order to improve the comfort of the wearer, the cuff 20 of the sphygmomanometer has a function of adjustable tightness. The user can tighten the cuff 20 only when starting blood pressure detection. However, the process of adjusting the tightness of the cuff 20 requires additional operations by the user, reducing the convenience of use of the blood pressure monitoring device.

[0030] The present invention provides a blood pressure monitoring device, aiming to solve the technical problem of how to improve the convenience of use of the blood pressure monitoring device.

[0031] In the embodiments of the present invention, as Figure 1 and Figure 2 shown, Figure 1 is a schematic structural diagram of an embodiment of the blood pressure monitoring device of the present invention; Figure 2 is a schematic cross-sectional view of an embodiment of the blood pressure monitoring device of the present invention.

[0032] The blood pressure monitoring device includes: a housing 10; a cuff 20, the cuff 20 encloses to form a wearing space 21, the cuff 20 includes an adjusting airbag 22 and a detecting airbag 23, the detecting airbag 23 is arranged on the side of the adjusting airbag 22 close to the wearing space 21, and the adjusting airbag 22 is used to push the detecting airbag 23 towards the wearing space 21 when inflated; an inflation assembly, the inflation assembly is installed on the housing 10, and the inflation assembly is communicated with the detecting airbag 23 and the adjusting airbag 22 to inflate the detecting airbag 23 and the adjusting airbag 22.

[0033] In this embodiment, the housing 10 is used to form the overall appearance structure of the blood pressure monitoring device. An installation cavity is provided inside the housing 10 for installing functional components. The blood pressure monitoring device may further include a pressure sensor. The inflation assembly includes an air pump and an air valve, etc. Among them, the air pump, the pressure sensor, and the air valve are installed inside the housing 10, and the cuff 20 is located outside the housing 10 and connected to the housing 10; the air pump, the pressure sensor, the air valve, and the cuff 20 are communicated through an air path (such as an air pipe).

[0034] The cuff 20 is used for the arm of the detection object to wear. After the detection object wears the cuff 20, the detection airbag 23 is wound around the user's arm. The air pump is used to inflate the detection airbag 23, the pressure sensor is used to detect the air pressure change in the detection airbag 23, and the air valve is used to control the deflation of the detection airbag 23. The principle of detecting blood pressure through the pressure sensor and the detection airbag 23 can refer to the oscillometric method or the oscillatory method. The principle is to automatically adjust the inflation amount of the detection airbag 23 wrapped around the upper arm, change the pressure, and there is a certain oscillatory wave when blood flows through the blood vessel. It is received by the pressure sensor and gradually deflated. According to the change of the oscillatory wave, the pressure and fluctuation detected by the pressure sensor also change. The moment with the largest fluctuation is selected as the reference point. Based on this point, a fluctuation point with a certain value is searched forward for the systolic blood pressure, and a fluctuation point with a certain value is searched backward for the diastolic blood pressure.

[0035] The cuff 20 can be in a wound shape or a cylindrical shape, which is not limited here, as long as it satisfies that the cuff 20 can enclose to form a wearing space 21. If the cuff 20 is in a cylindrical shape, the adjustment airbag 22 is located on the outer peripheral side of the detection airbag 23; if the cuff 20 is in a wound shape, the adjustment airbag 22 is wound in parallel with the detection airbag 23, and the detection airbag 23 forms the wall of the wearing space 21 to ensure that the detection airbag 23 can always effectively contact the arm of the detection object.

[0036] The inflation assembly can inflate the detection airbag 23 and the adjustment airbag 22 at the same time, or can first inflate the adjustment airbag 22, and then inflate the detection airbag 23 after the adjustment airbag 22 expands to a preset degree, which is not limited here.

[0037] After the adjustment airbag 22 is inflated and expanded, it can push the detection airbag 23 towards the wearing space 21, that is, shrink the wearing space 21. After the wearing space 21 is shrunk, the detection airbag 23 will automatically tighten the arm of the detection object passing through the wearing space 21, so that the air pressure force generated after the detection airbag 23 is inflated and expanded can fully act on the arm of the detection object.

[0038] After the user puts on the cuff 20, there is no need to adjust the cuff 20 itself. The user only needs to control the inflation assembly to inflate the adjustment airbag 22, so that the cuff 20 can automatically tighten the arm of the test subject. When the cuff 20 needs to be taken off, the adjustment airbag 22 can be directly controlled to deflate so that the cuff 20 loosens the arm of the test subject. In this way, the difficulty of adjusting the cuff 20 can be reduced, and the convenience of adjusting the tightness of the cuff 20 can be improved, so as to improve the convenience of using the blood pressure detection device.

[0039] Specifically, Figure 1 and Figure 2 As shown, the detection airbag 23 and the regulating airbag 22 are both arranged in a coiled shape, and one end of the detection airbag 23 outside the wearing space 21 is connected to one end of the regulating airbag 22 outside the wearing space 21.

[0040] The detection airbag 23 and the regulating airbag 22 are wound, so that the pushing effect on the detection airbag 23 is more obvious when the regulating airbag 22 is inflated, so as to more effectively reduce the wearing space 21, thereby improving the adjustment effect and efficiency of the cuff 20. The detection airbag 23 and the regulating airbag 22 are connected at the ends outside the wearing space 21, so that the detection airbag 23 and the regulating airbag 22 can always be kept parallel and opposite in the winding direction, and the detection airbag 23 and the regulating airbag 22 are prevented from staggering with each other due to different expansion conditions, thereby improving the structural stability of the cuff 20 during the inflation process.

[0041] For one end of the detection airbag 23 and the adjustment airbag 22 in the wearing space 21, the two ends in the wearing space 21 do not need to be connected to ensure that the adjustment airbag 22 can have a certain degree of deformation freedom when inflated, so that it can be fully deformed to fully push the detection airbag 23, thereby fully reducing the wearing space 21.

[0042] The inner cavities of the detection airbag 23 and the regulating airbag 22 may be independent of each other or may be interconnected.

[0043] For example, Figure 2 As shown, the inner cavities of the detection airbag 23 and the regulating airbag 22 are independent of each other, and the inflation component includes a first air pump and a second air pump. The first air pump is connected to the regulating airbag 22, and the second air pump is connected to the detection airbag 23.

[0044] The inner cavities of the detection airbag 23 and the regulating airbag 22 are independent of each other, which means that the inner cavities of the detection airbag 23 and the regulating airbag 22 are not connected to each other, so the detection airbag 23 and the regulating airbag 22 need to be inflated separately. The first air pump is used to inflate the regulating airbag 22, and the second air pump is used to inflate the detection airbag 23. The first air pump and the second air pump can make the inflation process of the regulating airbag 22 and the detection airbag 23 independent of each other, thereby improving the inflation efficiency and inflation process stability of the regulating airbag 22 and the detection airbag 23.

[0045] The first air pump and the second air pump can respectively inflate the detection airbag 23 and the adjustment airbag 22 through different air path components 30, or can respectively inflate the detection airbag 23 and the adjustment airbag 22 through the same air path component 30.

[0046] Specifically, as Figure 2 shown, the inflation assembly further includes an air path component 30, and the air path component 30 is formed with independent first and second air flow channels 31 and 32. The first air pump and the second air pump are both connected to the air path component 30, and the detection airbag 23 and the adjustment airbag 22 are both connected to the air path component 30. The first air flow channel 31 communicates the first air pump with the adjustment airbag 22, and the second air flow channel 32 communicates the second air pump with the detection airbag 23.

[0047] Integrating the first air flow channel 31 and the second air flow channel 32 into the same air path component 30 and making the first air flow channel 31 and the second air flow channel 32 independent of each other can not only ensure that the inflation processes of the detection airbag 23 and the adjustment airbag 22 do not affect each other, but also reduce the number of air path components 30, making the internal structure of the blood pressure monitoring device simpler and more compact.

[0048] Exemplarily, as Figure 2 shown, the air path component 30 is provided with a first mounting hole and a second mounting hole. The first mounting hole communicates with the first air flow channel 31, and the second mounting hole communicates with the second air flow channel 32. The blood pressure monitoring device further includes a main control board, a first pressure sensor 41 and a second pressure sensor 42. The first pressure sensor 41 is mounted in the first mounting hole, and the second pressure sensor 42 is mounted in the second mounting hole.

[0049] Both the first pressure sensor 41 and the second pressure sensor 42 are electrically connected to the main control board. The first pressure sensor 41 is used to detect the air pressure in the adjustment airbag 22, and the second pressure sensor 42 is used to detect the air pressure in the detection airbag 23. The main control board is used to turn off the first air pump according to the air pressure in the adjustment airbag 22, and receive, convert and output the change of the air pressure in the detection airbag 23.

[0050] The first pressure sensor 41 can detect the change of the air pressure in the adjustment airbag 22 by detecting the change of the air pressure in the first air flow channel 31, and then transmit the air pressure change signal to the main control board. When the air pressure in the adjustment airbag 22 increases to a preset value, it means that the adjustment airbag 22 has expanded to the preset degree. At this time, the main control board controls the first air pump to turn off to stop inflating the adjustment airbag 22. In this way, the automatic control of the inflation process of the adjustment airbag 22 can be realized without manual control by the user, so as to improve the use convenience of the blood pressure monitoring device.

[0051] The second pressure sensor 42 can detect the air pressure change in the airbag 23 by detecting the air pressure change in the second air flow channel 32, and then transmit the air pressure change signal to the main control board. The main control board can calculate and convert the air pressure change signal into a blood pressure signal of the detection object, and output the blood pressure signal to the result output module for the user to obtain. Installing both the first pressure sensor 41 and the second pressure sensor 42 on the air path component 30 can improve the integration degree of the functional components of the blood pressure monitoring device on the air path component 30, thereby making the internal structure of the blood pressure monitoring device further simple and compact, reducing the installation difficulty of the functional components of the blood pressure monitoring device, and improving the installation efficiency.

[0052] Specifically, as Figure 2 shown, the adjustment airbag 22 is provided with an avoidance hole, the housing 10 is provided with a first through hole and a second through hole, and the second through hole is opposite to the avoidance hole; the blood pressure monitoring device further includes a first air nozzle 51 and a second air nozzle 52. One end of the first air nozzle 51 is communicated with the adjustment airbag 22, and the other end passes through the first through hole to be communicated with the air path component 30; one end of the second air nozzle 52 is communicated with the detection airbag 23, and the other end passes through the avoidance hole and the second through hole to be communicated with the air path component 30.

[0053] It should be noted that the avoidance hole penetrates through the adjustment airbag 22 in the thickness direction, and the hole wall of the avoidance hole seals and closes the inner cavity of the adjustment airbag 22. That is to say, the inner cavity of the adjustment airbag 22 will not be communicated with the external environment through the avoidance hole. In the outermost winding layer of the adjustment airbag 22 and the detection airbag 23, the adjustment airbag 22 is located between the detection airbag 23 and the housing 10. Therefore, the second air nozzle 52 needs to pass through the avoidance hole to communicate the detection airbag 23 with the air path component 30, so as to simplify the connection mode between the detection airbag 23 and the air path component 30, and make the connection structure between the cuff 20 and the housing 10 more simple and compact.

[0054] In practical applications, the inflation assembly further includes a first air valve (not shown in the figure) and a second air valve (not shown in the figure). The first air valve is communicated with the first air flow channel 31, and the second air valve is communicated with the second air flow channel 32. The first air valve is used to control the deflation of the adjustment airbag 22, and the second air valve is used to control the deflation of the detection airbag 23. In this way, the adjustment airbag 22 and the detection airbag 23 can be deflated and contracted in time after the work is completed, and the deflation processes are independent of each other.

[0055] Exemplarily, as Figure 1 and Figure 3As shown, the cuff 20 further includes a support plate 24. The shape of the support plate 24 is the same as that of the adjustment airbag 22 and the detection airbag 23. The adjustment airbag 22 and the detection airbag 23 are arranged on one side of the support plate 24 close to the wearing space 21. Since the support plate 24 is not deformable, the distance between the user's arm and the support plate 24 is fixed. When the adjustment airbag 22 is inflated and expands, the support plate 24 can limit the deformation of the adjustment airbag 22 in the direction away from the wearing space 21, so that the adjustment airbag 22 deforms into the wearing space 21 as much as possible, so as to push the detection airbag 23 effectively towards the arm of the detection object, thereby further improving the tightening effect of the cuff 20.

[0056] Specifically, as Figure 1 shown, the cuff 20 further includes a protective sleeve 25. The adjustment airbag 22, the detection airbag 23 and the support plate 24 are all arranged inside the protective sleeve 25. The protective sleeve 25 can hide and protect the adjustment airbag 22 and the detection airbag 23, avoiding direct contact and friction between the adjustment airbag 22 and the detection airbag 23 and the external environment, so as to extend the working life of the adjustment airbag 22 and the detection airbag 23. In addition, the protective sleeve 25 can also improve the touch of the cuff 20 on the user's arm to improve the user's wearing experience.

[0057] The support plate 24 can be connected to the housing 10 or not connected to the housing 10.

[0058] In practical applications, as Figure 1 and Figure 3 shown, the support plate 24 is convexly provided with a buckle, and the housing 10 is provided with a card slot, and the buckle is engaged with the card slot. The support plate 24 is a rigid structure, and the connection structure formed by it and the housing 10 is more stable. Connecting the housing 10 by the support plate 24 can improve the connection stability of the overall cuff 20 and the housing 10, thereby improving the structural stability of the overall blood pressure monitoring device.

[0059] In the technical solution of the blood pressure monitoring device of the present invention, the cuff 20 includes an adjustment airbag 22 and a detection airbag 23. When the blood pressure monitoring device works, after the adjustment airbag 22 is inflated and expands, it can squeeze the detection airbag 23 towards the arm of the detection object, so that the detection airbag 23 wraps tightly around the arm of the detection object, so that the detection airbag 23 can effectively apply pressure to the arm of the detection object after being inflated and expanded. Thus, the cuff 20 can automatically wrap tightly around the arm of the detection object during the inflation process, without the user manually adjusting the cuff 20 additionally, so as to reduce the operation steps of the user and improve the use convenience of the blood pressure monitoring device.

[0060] The above are only alternative embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
