[0024] Some embodiments of the present disclosure will be described in detail with reference to the drawings, of which examples are shown. The following description, in relation to the drawings, refers to the same or similar elements using the same or similar reference numerals throughout. Various changes, modifications and equivalents thereof will become apparent to those skilled in the art after an understanding of the present disclosure. For example, the order of the operations described herein is merely an example, and is not limited to those set forth herein, but can be changed as apparent after an understanding of the present disclosure, except for operations that must be performed in a specific order. In addition, the description of features known in the art can be omitted for the sake of clarity and brevity.

[0025] The implementations described in some embodiments of the present disclosure are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] Some embodiments of the present disclosure provide a blood pressure measuring device applied to a blood pressure measuring scene.

[0027] In the related art, during use of a barrel type electronic sphygmomanometer, a user needs to place an upper arm into an arm barrel and position it, and a preset position of the upper arm is pressed by a pressurizing air bag in the arm barrel to block blood flow in the upper arm for blood pressure measurement. If the user fails to position the upper arm, the pressurizing air bag in the arm barrel will be offset on the upper arm, and the blood flow in the brachial artery of the upper arm cannot be effectively blocked, thereby causing inaccurate blood pressure measurement. However, when the user places the upper arm into the arm barrel, it is difficult to determine whether the upper arm has been positioned.

[0028] In view of this, some embodiments of the present disclosure provide a blood pressure measuring device, which is provided with an arm barrel and an arm support for placing an upper arm and a lower arm of a user, respectively. An elbow support is arranged between the arm barrel and the arm support, and is used for placing an elbow of the user and detecting whether the elbow of the user is placed on the elbow support. When the elbow support detects that the elbow of the user is placed on the elbow support, it indicates that the upper arm of the user has been positioned, and thus in blood pressure measurement, the air bag can accurately press the preset position of the upper arm, effectively block the blood flow in the brachial artery of the upper arm, and ensure the accuracy of the blood pressure measurement result.

[0029] Figure 1 FIG. 1 is a structural schematic diagram of a blood pressure measuring device according to some embodiments of the present disclosure. Figure 2 FIG. 2 is a structural schematic diagram of an arm barrel and an elbow support according to some embodiments of the present disclosure. Figure 3 FIG. 3 is a top view of an arm barrel and an elbow support according to some embodiments of the present disclosure. As shown in FIG. 3, the arm barrel and the elbow support are arranged in a staggered manner. Figures 1 to 3As shown, the blood pressure measuring device comprises a base 1, an arm cylinder 2, an arm support 3 and an elbow support 4. The arm cylinder 2 is arranged on the base 1, the arm cylinder 2 is in a tubular structure, and an air bag (not shown in the figure) is arranged on the inner side wall of the tubular structure of the arm cylinder 2. The air bag is used to wrap the upper arm of the user and apply pressure to the upper arm of the user to block the blood flow. The arm support 3 is arranged on the base 1, and one opening end of the arm cylinder 2 faces the arm support 3. The arm support 3 comprises a first supporting surface 31, the first supporting surface 31 faces away from the base 1, and the first supporting surface 31 is used to place the forearm of the user. The elbow support 4 is arranged on the base 1, and the elbow support 4 is located between the arm cylinder 2 and the arm support 3. The elbow support 4 is used to support the elbow of the user, and the elbow support 4 comprises a detection device 43. A preset distance L is arranged between the detection device 43 and the arm cylinder 2, and the detection device 43 is used to detect whether the elbow of the user is placed on the elbow support 4.

[0030] Before the blood pressure measurement, the hand of the user is inserted into the arm cylinder 2 from the opening end of the arm cylinder 2 away from the arm support 3, and the arm cylinder 2 is taken out from the opening end of the arm cylinder 2 close to the arm support 3 until the forearm of the user is placed on the first supporting surface 31 of the arm support 3. At this time, if the upper arm of the user is not placed in place, that is, the elbow of the user is located in the arm cylinder 2 or on the first supporting surface 31 of the arm support 3, the elbow of the user will not trigger the detection device 43 located on the elbow support 4, thereby reminding the user that the upper arm is not placed in place. At this time, if the upper arm of the user is placed in place, that is, the elbow of the user is located on the elbow support 4 and triggers the detection device 43, thereby reminding the user that the upper arm has been placed in place, and the blood pressure measurement can be started. The detection device 43 and the arm cylinder 2 are arranged with a preset distance L, so that the detection device 43 can match the position of the elbow of the user when the upper arm of the user is placed in place, that is, when the upper arm of the user is placed in place, the elbow of the user is taken out of the arm cylinder 2 from the opening end of the arm cylinder 2 close to the arm support 3. Therefore, whether the upper arm of the user is placed in place can be prompted by whether the detection device 43 is triggered. After the upper arm of the user is placed in place, the blood pressure measurement can be performed, and the accurate blood pressure value of the user can be obtained.

[0031] It should be noted here that the preset distance L is not specifically limited in the present disclosure. The preset distance L between the detection device 43 and the arm cylinder 2 satisfies that the upper arm of the user is placed in place, that is, when the elbow of the user is taken out of the arm cylinder 2 and located on the elbow support 4, the elbow of the user can trigger the detection device 43.

[0032] In some embodiments, the detection device 43 located on the elbow support 4 does not contact the air bag located in the arm cylinder 2, so as to avoid that the air bag mistakenly triggers the detection device 43.

[0033] Figure 4 It is a structural schematic diagram of an elbow support according to some embodiments of the present disclosure. Figure 5 It is an exploded view of an elbow support according to some embodiments of the present disclosure. Figure 6is a front view of the elbow rest according to some embodiments of the present disclosure. As shown in Figure 1 、 Figure 4 、 Figure 5 and Figure 6 shown, in some embodiments, the elbow rest 4 further comprises an elbow rest base 44. The elbow rest base 44 is arranged on the base 1, and the elbow rest base 44 comprises a second support surface 41 which faces away from the base 1 and is used to place the elbow of the user. The detection device 43 is arranged on the second support surface 41, so that when the elbow of the user is placed on the second support surface 41, the detection device 43 can be triggered.

[0034] In some embodiments, the detection device 43 comprises a button cap 431 and a pressure switch 432. As shown in Figure 4 and Figure 5 , the elbow rest base 44 has a shell structure, and the second support surface 41 is provided with a mounting hole 411, and the button cap 431 is movably arranged in the mounting hole 411, i.e. the button cap 431 is arranged in the mounting hole 411 and can move in the axial direction of the mounting hole 411. The pressure switch 432 is arranged inside the elbow rest base 44, and the movable button cap 431 is used to trigger the pressure switch 432.

[0035] For example, when the upper arm of the user is placed in place, i.e. the elbow of the user is extended to the elbow rest 4, the elbow of the user can press the button cap 431 on the second support surface 41, thereby triggering the pressure switch 432 to detect whether the elbow of the user is placed on the elbow rest 4.

[0036] In some embodiments, as shown in Figure 5 and 6 , the button cap 431 comprises a third support surface 4310 which faces away from the pressure switch 432, and the second support surface 41 is a concave curved surface, and the third support surface 4310 is also a concave curved surface, and the third support surface 4310 matches the second support surface 41. Among them, the elbow of the user presses the button cap 431 through the third support surface 4310 to trigger the pressure switch 432, and the second support surface 41 is used to provide support for the elbow of the user during blood pressure detection. Therefore, the second support surface 41 and the third support surface 4310 are respectively arranged as matching concave curved surfaces, which can adapt to the elbow of the user, thereby improving the comfort of the embodiments of the present disclosure.

[0037] In some embodiments, when the button cap 431 does not trigger the pressure-sensitive switch 432, the third supporting surface 4310 protrudes from the second supporting surface 41, i.e., part of the button cap 431 protrudes from the elbow rest base 44, facilitating the elbow to press the button cap 431. When the button cap 431 triggers the pressure-sensitive switch 432, the third supporting surface 4310 is flush with the second supporting surface 41. At this time, the third supporting surface 4310 and the second supporting surface 41 jointly support the user's elbow, and the third supporting surface 4310 being flush with the second supporting surface 41 can effectively improve the comfort when supporting the user's elbow.

[0038] In some embodiments, the user's elbow presses the button cap 431, causing the button cap 431 to move downward by a preset displacement, and triggering the pressure-sensitive switch 432.

[0039] For example, when the user's upper arm is placed in position, i.e., the user's elbow extends out of the arm cylinder 2 to the elbow rest 4, the user's elbow can press the button cap 431 located on the second supporting surface 41, causing the button cap 431 to move downward by 3 mm and triggering the pressure-sensitive switch 432. It should be noted that although the button cap 431 triggers the pressure-sensitive switch 432 by moving downward by 3 mm is taken as an example, the preset displacement of the button cap 431 moving downward is not limited in the embodiments of the present disclosure.

[0040] In some embodiments, the detection device 43 further comprises a spring (not shown in the figure), which is used to reset the button cap 431. The side of the button cap 431 facing the pressure-sensitive switch 432 is provided with a buckle 4311 and a guide column 4312, the button cap 431 is buckled to the mounting hole 411 through the buckle 4311, the elbow rest base 44 is provided with a guide hole 442, the guide column 4312 is located in the guide hole 442, and the guide hole 442 and the guide column 4312 are used to limit the movement direction of the button cap 431, so that the button cap 431 can move in the axial direction of the guide column 4312. The spring is sleeved on the guide column 4312, one end of the spring is connected with the guide hole 442, and the other end of the spring is connected with the button cap 431. When the user's elbow presses the button cap 431 to trigger the pressure-sensitive switch 432, the spring is compressed. When the button cap 431 is not pressed, the spring is stretched, and the third supporting surface 4310 of the button cap 431 protrudes from the second supporting surface 41.

[0041] In some embodiments, the elbow rest base 44 is provided with a clamping groove 441 matched with the buckle 4311, and the button cap 431 is installed in the mounting hole 411 through the buckling of the buckle 4311 and the clamping groove 441. When the button cap 431 is not pressed, the spring is stretched, the third supporting surface 4310 of the button cap 431 protrudes from the second supporting surface 41, and part of the button cap 431 protrudes from the elbow rest base 44 under the action of the buckle 4311 and the clamping groove 441.

[0042] In some embodiments, the axis of the arm cylinder 2 and the first support surface 31 have a preset angle R, and the preset angle R is less than 180°. When the user uses the blood pressure measuring device of the embodiments of the present disclosure to measure blood pressure, the direction of the axis of the arm cylinder 2 can represent the length direction of the upper arm of the user, and the first support surface 31 can represent the plane in which the length direction of the lower arm of the user is located. The preset angle R between the axis of the arm cylinder 2 and the first support surface 31, that is, the angle between the upper arm and the lower arm of the user. The preset angle R is less than 180°, which is used to control the user to keep the upper arm and the lower arm in a bent state when using the blood pressure measuring device of the embodiments of the present disclosure to measure blood pressure. When the upper arm and the lower arm of the user are in a bent state, the elbow of the user protrudes outward compared to the whole arm, which facilitates better triggering of the detection device 43 located on the elbow support 4, thereby improving the accuracy of the detection device 43.

[0043] In some embodiments, the arm cylinder 2 and / or the arm support 3 are movably arranged on the base, which is used to adjust the preset angle R, that is, to adjust the bending degree of the upper arm and the lower arm of the user, so as to improve the adaptability of the embodiments of the present disclosure.

[0044] In some embodiments, the arm cylinder 2 and the elbow support 4 are fixedly connected. The elbow support 4 is movably connected with the base 1, that is, the arm cylinder 2 is movably connected with the base 1 through the elbow support 4, which is used to adjust the preset angle R.

[0045] In some embodiments, as shown in Figure 4 The main body of the elbow support 4 is in a columnar structure, and both ends of the columnar structure of the elbow support 4 are provided with a rotating shaft 42, and the elbow support 4 is rotatably connected with the base 1 through the rotating shaft 42. The arm cylinder 2 is fixed to the side surface of the columnar structure of the elbow support 4.

[0046] The axis of the rotating shaft 42 is perpendicular to the axis of the arm cylinder 2, so that the arm cylinder 2 can rotate through the rotating shaft 42 to change the direction of the axis of the arm cylinder 2, thereby adjusting the preset angle R.

[0047] In some embodiments, the arm cylinder 2 includes a ring-shaped mounting plate 21, which is located at one end of the arm cylinder 2 close to the arm support 3. The mounting plate 21 is fixedly connected with the elbow support base 44, thereby realizing the fixation of the arm cylinder 2 to the elbow support 4.

[0048] In some embodiments, the detection device 43 is used to detect that one side surface of the elbow of the user is located on the side surface of the columnar structure of the elbow support 4 and extends along the axis direction of the columnar structure of the elbow support 4, that is, the third support surface 4310 of the button cap 431 is located on the side surface of the columnar structure of the elbow support 4 and extends along the axis direction of the columnar structure of the elbow support 4. By extending the third support surface 4310 of the button cap 431, the detectable range of the detection device 43 is expanded, thereby improving the accuracy of the detection device 43.

[0049] In the detailed description above, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration specific aspects in which the disclosure can be practiced.

To this end, the directional terminology is used only for purposes of illustration and is not intended to limit the concepts of the present disclosure. It is to be understood that other aspects can be utilized and structural or logical changes can be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense, as the scope of the present disclosure is defined by the claims.

[0050] It is to be understood that the terminology used herein is for the purpose of describing various aspects of some embodiments of the present disclosure only and is not intended to be limiting, unless specifically made so in the claims. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items; it will be understood that the terms “coupled,” “attached,” “connected,” “joined,” “linked,” “fixed” and the like used herein can have the broadest possible interpretation in accordance with the principles of civil engineering, mechanical engineering, electrical engineering, and the like, such that they can connote the idea of being either fixedly or detachably connected, integral, mechanically connected, electrically connected, in communication with each other, directly connected, or indirectly connected via intervening medium, or an interaction relationship between two elements, unless otherwise specifically defined. The specific meaning of the above terms in this context can be understood by those of ordinary skill in the art according to the specific circumstances.

[0051] Further, the word “over” used in the context of a component, an element, or a layer “over” another component, element, or layer herein is used to describe a positioning (e.g., placement, formation, deposition, etc.) of the component, element, or layer “indirectly” on the other component, element, or layer such that one or more additional components, elements, or layers are arranged between the other component, element, or layer and the component, element, or layer. However, the word “over” used in the context of a component, an element, or a layer “over” another component, element, or layer can optionally also have a specific meaning: the component, element, or layer is positioned (e.g., placed, formed, deposited, etc.) “directly” on the other component, element, or layer, e.g., in direct contact with the other component, element, or layer.

[0052] It will be understood that spatially relative terms, such as "above", "upper", "below", and "lower", are used herein for ease of description to describe the elements as they are oriented in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures.

These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or importance. In fact, the expressions "first", "second" and the like can be used interchangeably. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the disclosure.

[0055] In the description herein, "a plurality of means at least two, refers to two or more, for example, two, three, etc., unless otherwise expressly specified. Other quantifiers are similar. The singular forms "a", "said" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise. In addition, the articles "a" and "an" as used in this application and the appended claims are generally understood as taking the meaning of "one or more" unless otherwise specified or clearly directed to the singular form from the context.

As used in this document, the term "and / or" includes any one of the associated listed items, as well as any combination of any two or more of the associated listed items; "and / or", describes an associating relationship of associated objects, indicates that there can be three relationships, for example, A and / or B, can represent: A exists alone, A and B exist together, B exists alone, these three cases. The character " / " generally represents that the front and rear associated objects are a "or" relationship. Similarly, "at least one of" includes any one of the associated listed items, as well as any combination of any two or more of the associated listed items.

[0057] In addition, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the word "exemplary" is used herein to present concepts in one form for illustrative purposes. As used in this document, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or as is clear from the context, the phrase "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, the phrase "X employs A or B" is satisfied by any of the following instances: X employs A; X employs B; or X employs both A and B.
