[0029] With the improvement of people's living standards and the increasing attention to physical health, more and more families are equipped with various home medical devices to facilitate the simple management of family members' health. Sphygmomanometers have become a common health monitoring device in people's daily lives. In the sphygmomanometers in related technologies, the airbag usually has only one large-volume cavity. When the airbag needs to be expanded to increase the pressure on the arm of the monitored object, the entire cavity needs to be inflated. The time and gas volume required for inflation are relatively large, resulting in low working efficiency and high energy consumption of the blood pressure monitoring device.

[0030] The utility model provides a blood pressure monitoring device, aiming to solve the technical problem of how to improve the working efficiency of the blood pressure monitoring device and reduce energy consumption.

[0031] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, Figure 1 This is a structural exploded view of an embodiment of the blood pressure monitoring device of the utility model; Figure 2 It is a schematic structural diagram of an embodiment of the airbag 21 in the present utility model.

[0032] The blood pressure monitoring device includes: a housing 10; a cuff 20, wherein the cuff 20 is connected to the housing 10, and the cuff 20 includes an airbag 21, which is arranged in a cylindrical or coiled shape, and includes at least two capsule bodies 211, and the at least two capsule bodies 211 are arranged along the width direction of the airbag 21.

[0033] In this embodiment, the housing 10 is used to form the overall appearance structure of the blood pressure monitoring device, and a mounting cavity is provided in the housing 10, and the mounting cavity is used for installing functional components. The blood pressure monitoring device may also include a detection component, and the detection component includes an air pump, a pressure sensor, an air valve, etc. Among them, the air pump, the sensor and the air valve are installed in 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 connected through an air path (such as an airway).

[0034] The cuff 20 is used to be worn on the user's arm. After the user wears the cuff 20, the airbag 21 is wrapped around the user's arm. The air pump is used to inflate the airbag 21, the pressure sensor is used to detect the air pressure change in the airbag 21, and the air valve is used to control the deflation of the airbag 21. The principle of detecting blood pressure through the pressure sensor and the airbag 21 can refer to the oscillometric method or the oscillation method. The principle is to automatically adjust the inflation amount of the airbag 21 wrapped around the upper arm to change the pressure. The blood flow through the blood vessels has a certain oscillation wave, which is received by the pressure sensor and gradually deflated. According to the change of the oscillation wave, the pressure and fluctuation detected by the pressure sensor also change accordingly. The moment with the largest fluctuation is selected as the reference point. Based on this point, the fluctuation point of a certain value is found forward as the systolic pressure, and the fluctuation point of a certain value is found backward as the diastolic pressure.

[0035] The number of the capsules 211 may be two, or three or more. For ease of description, the number of the capsules 211 is referred to as "multiple" below. The width direction of the airbag 21 refers to the extension direction of the central axis of the airbag 21 when the airbag 21 is in a cylindrical or coiled shape. Two adjacent capsules 211 may be connected or not; if two adjacent capsules 211 are not connected, the multiple capsules 211 need to be installed on a common support member so that the multiple capsules 211 maintain a stable positional relationship.

[0036] On the premise that the overall appearance dimensions are the same, the sum of the inner cavity volumes of the multiple balloons 211 is smaller than the inner cavity volume of a single integral airbag 21. Therefore, when the multiple balloons 211 are inflated, the time and amount of gas required for the multiple balloons 211 to expand to a preset size are less than those of the integral airbag 21, thereby shortening the time required for inflation and reducing the amount of gas required for inflation, thereby improving the inflation efficiency of the airbag 21 and reducing the energy consumption for inflation of the airbag 21.

[0037] like Figure 3 As shown, Figure 3 It is a projection diagram of an embodiment of the airbag 21 in the utility model. It can be understood that under the same conditions, the pressure on the arm after the multiple capsules 211 are inflated is not much different from the pressure on the arm after the integral airbag 21 is inflated, and the part between two adjacent capsules 211 that cannot be inflated does not affect the contact area of ​​the multiple capsules 211 on the arm. In other words, dividing the airbag 21 into multiple capsules 211 can not only produce a preset pressure effect and pressure area on the arm after inflation, but also shorten the time required for inflation and reduce the amount of gas required for inflation, so as to improve the inflation efficiency of the airbag 21 and reduce the inflation energy consumption of the airbag 21.

[0038] The inner cavities of two adjacent capsules 211 may be interconnected or isolated from each other, which is not limited here.

[0039] like Figure 2 and Figure 3 As shown, the airbag 21 further includes a connecting piece 212, which is disposed between two adjacent bladder bodies 211. The connecting piece 212 is provided with an air passage, which connects the inner cavities of the two adjacent bladder bodies 211. Thus, when the airbag 21 is inflated, only one of the multiple bladder bodies 211 needs to be inflated, and the air flow can flow to the other bladder bodies 211 through the air passage, so that all the multiple bladder bodies 211 can be inflated, and there is no need to inflate the multiple bladder bodies 211 separately, thereby simplifying the inflation process of the multiple bladder bodies 211, thereby simplifying the air path structure of the blood pressure monitoring device.

[0040] The connecting piece 212 may be a hard piece or a soft piece; the material of the connecting piece 212 may be the same as the material of the capsule 211 or may be different from the material of the capsule 211, which is not limited here.

[0041] Specifically, the material of the connecting piece 212 is the same as that of the bladder body 211, thereby simplifying the production and processing of the connecting piece 212, and there is no need to prepare a material different from that of the bladder body 211. In addition, when the airflow passes through the connecting piece 212, the connecting piece 212 can be temporarily expanded, thereby increasing the flow cross section of the connecting piece 212, thereby increasing the circulation speed of the airflow, and further improving the inflation efficiency.

[0042] The connecting piece 212 and the capsule 211 can be processed and formed separately and then connected together, or they can be processed and formed as one piece. In practical applications, the connecting piece 212 and at least two capsules 211 are formed as one piece, so that the production and processing methods of the connecting piece 212 and the connection method of the connecting piece 212 and the capsule 211 can be simplified, and the production and processing convenience of the airbag 21 can be improved.

[0043] The inner cavities of two adjacent capsules 211 may be connected via only one connecting piece 212, or may be connected via two or more connecting pieces 212. For example, Figure 2 As shown, at least two connecting pieces 212 are provided between two adjacent capsules 211, and the at least two connecting pieces 212 are arranged at intervals along the circumferential direction or the winding direction of the airbag 21. In this way, the connecting positions of the two adjacent capsules 211 can be increased to increase the airflow flow per unit time between the two adjacent capsules 211, thereby increasing the airflow flow speed between the two adjacent capsules 211.

[0044] For example, Figures 1 to 3 As shown, the airbag 21 further includes a connecting portion 213, which is disposed between two adjacent capsules 211, and the two sides of the connecting portion 213 are respectively connected to the two adjacent capsules 211. The connecting portion 213 can connect the two adjacent capsules 211 together, thereby improving the overall structural stability of the airbag 21.

[0045] The material of the connection portion 213 may be the same as or different from the material of the capsule 211 .

[0046] Exemplarily, the material of the connecting portion 213 is the same as that of the bladder body 211, thereby simplifying the production and processing methods of the connecting portion 213, and there is no need to prepare a separate material different from the bladder body 211; and the connecting portion 213 can also adapt to the expansion or contraction process of the bladder body 211 and deform, so as to improve the effect of the deformation of the airbag 21 on the user's arm, thereby improving the user experience.

[0047] The connecting portion 213 and the capsule 211 may be formed separately and then connected together, or may be formed as one piece. Specifically, the connecting portion 213 and at least two capsules 211 are formed as one piece. This simplifies the production and processing of the connecting portion 213 and the connection between the connecting portion 213 and the capsule 211, and improves the production and processing convenience of the airbag 21.

[0048] The connecting portion 213 may connect only part of the side edges of two adjacent capsules 211, or may connect all the side edges of two adjacent capsules 211. Figure 2 and Figure 3As shown, the connecting portion 213 extends along the circumferential or winding direction of the two adjacent capsules 211. In this way, the length dimension of the connecting portion 213 can be equivalent to the circumferential dimension of the capsule 211, thereby increasing the connection area between the connecting portion 213 and the two adjacent capsules 211 and improving the connection stability between the connecting portion 213 and the two adjacent capsules 211.

[0049] For example, Figure 1 and Figure 4 As shown, Figure 4 The cuff 20 is a schematic structural diagram of an embodiment of the present invention. The cuff 20 further includes a support plate 22, which is arranged in a cylindrical or coiled shape corresponding to the airbag 21, and the cuff 20 is arranged to form a wearing space 24, and the support plate 22 is arranged on the side of the airbag 21 away from the wearing space 24.

[0050] The wearing space 24 is used for the user's arm to pass through. Since the support plate 22 is not deformable, the distance between the user's arm and the support plate 22 is fixed. When the airbag 21 is inflated, the support plate 22 can limit the deformation of the multiple capsules 211 in the direction away from the wearing space 24, so that the multiple capsules 211 are deformed into the wearing space 24 as much as possible, so that the multiple capsules 211 can fully and effectively squeeze the user's arm, thereby improving the effect of applying force to the user's arm.

[0051] Specifically, Figure 1 As shown, the cuff 20 further includes a protective cover 23, which is arranged in a cylindrical or coiled shape corresponding to the airbag 21, and the airbag 21 is arranged in the protective cover 23. The protective cover 23 can hide and protect the airbag 21, and prevent the airbag 21 from directly contacting and rubbing with the external environment, thereby extending the working life of the airbag 21. In addition, the protective cover 23 can also improve the touch of the cuff 20 on the user's arm to improve the user experience.

[0052] In the technical solution of the blood pressure monitoring device of the utility model, the airbag 21 is set as at least two connected bladders 211, which can reduce the total volume of the at least two bladders 211, thereby reducing the time and gas volume required to inflate the at least two bladders 211, so as to improve the inflation efficiency of the airbag 21 and reduce the inflation energy consumption. After the at least two bladders 211 are inflated, they can increase the pressure on the arm of the test object, which is the same as the pressure effect generated by the integrated airbag 21, so it will not affect the blood pressure monitoring result of the test object. In this way, the working efficiency of the blood pressure monitoring device can be improved and the energy consumption can be reduced.

[0053] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
