Description

Technical Field

[0001] This application relates to the field of medical and health technology, and in particular to an adaptive cuff for a blood pressure monitor and a blood pressure monitor. Background Technology

[0002] For existing blood pressure monitors, most of them currently use a fan-shaped or long strip-shaped Velcro cuff. The cuff is wrapped around the user's arm or wrist, and after determining the tightness, it is secured to begin measuring blood pressure.

[0003] However, the scope of use of this type of cuff is limited, and patients may not be able to properly control the tightness of the cuff when using it, which may lead to problems such as inaccurate blood pressure measurement.

[0004] It should be noted that the above description of the background technology is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background technology section of this application. Utility Model Content

[0005] The inventors discovered that in the existing structure described above, the space occupied by the Velcro cannot be used efficiently, which can easily lead to a mismatch between the cuff and the arm circumference. Furthermore, when using this type of cuff, the cuff tends to spring back when the user wraps it around the arm, making it difficult for the patient to control the tightness of the cuff with one hand. This results in inconvenient operation, such as cumbersome wrapping steps and long time required to fix the cuff. It may also lead to inaccurate blood pressure measurements due to improper tightness and / or noise from the Velcro during measurement.

[0006] To address one of the aforementioned problems or other similar issues, embodiments of this application provide an adaptive cuff for a blood pressure monitor and a blood pressure monitor itself. This allows users to quickly and conveniently perform a series of actions, such as putting on the cuff, adjusting its tightness, and removing it, with just one hand, thereby improving operational convenience and enhancing the accuracy of blood pressure measurement.

[0037] The embodiments of this application will now be described with reference to the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the scope of this application.

[0038] First aspect of the embodiments

[0039] An embodiment of the first aspect of this application provides an adaptive cuff for a blood pressure monitor. Figure 1 This is a schematic diagram of an adaptive cuff according to an embodiment of the first aspect of this application; Figure 2 This is a schematic diagram of the main body of the cuff according to the first aspect of this application; Figure 3 This is a schematic diagram of the initial and tightened states of the cuff body of the first aspect of this application; Figure 4 This is a schematic diagram of the initial and tightened states of the adaptive cuff of the first aspect of this application.

[0040] like Figures 1 to 4 As shown, the adaptive cuff 1 may include: a cuff body 10, an air bag 20, a first fabric piece 30, and a cuff fastening part 40. The two circumferential ends of the cuff body 10 (one end 101 and the other end 102 in the circumferential direction) are intersected and overlapped to form a ring structure with an adjustable circumferential length. That is, the cuff body 10 forms a self-intersecting ring structure. A portion of the air bag 20 is disposed on the radially inner side of the cuff body 10, and the two circumferential ends of the air bag 20 (one end 201 and the other end 202 in the circumferential direction) are fixedly connected to the cuff body 10. The first fabric piece 30 is disposed on the radially outer side of the cuff body 10 and is fixedly connected to the cuff body 10. The cuff fastening part 40 is disposed on the radially outer side of the cuff body 10 and is fixedly connected to the first fabric piece 30.

[0041] According to the above embodiments, by designing the cuff body 10 as a self-intersecting ring structure and by providing a first fabric piece 30 fixedly connected to the cuff body 10 and a cuff fastening part 40 fixedly connected to the first fabric piece 30, users can quickly and conveniently complete a series of actions such as putting on the cuff, adjusting the tightness, and taking off the cuff with one hand, thereby improving operational convenience; and because the first fabric piece 30 and the cuff fastening part 40 are used to tighten and secure the cuff, no noise will be generated during the measurement process, which will affect the accuracy of blood pressure measurement, thus contributing to the improvement of blood pressure measurement accuracy.

[0042] In this embodiment of the application, when blood pressure needs to be measured, the cuff fastening part 40 is operated with one hand, thereby driving the first fabric piece 30 fixedly connected to the cuff fastening part 40 and the cuff body 10 fixedly connected to the first fabric piece 30, thereby achieving the purpose of tightening the cuff body 10 (e.g., Figure 3 and Figure 4 (As shown in the right-hand diagram); After measuring blood pressure, by pressing the cuff fastening part 40 with one hand, and then utilizing the elasticity of the cuff body 10, the cuff body 10 automatically loosens the arm, thus automatically relaxing the cuff body 10 back to its initial state (as shown in the diagram on the right); Figure 3 and Figure 4 (As shown in the left figure), this makes it convenient for the user to pull the arm out of the cuff body 10 after the measurement is completed.

[0043] In the embodiments of this application, the fixed connection between the first fabric piece 30 and the air bag 20 and the sleeve body 10 can be achieved in any way, such as welding, snap-fitting, riveting, etc.

[0044] In the embodiments of this application, such as Figure 2 As shown, one end 101 of the cuff body 10 is provided with a first through hole H1 that penetrates the cuff body 10 in the radial direction and a second through hole H2 that penetrates the cuff body 10 in the radial direction and is located on the side of the end E2 away from the first through hole H1 in the circumferential direction; the other end 102 of the cuff body 10 is provided with a fourth through hole H4 that penetrates the cuff body 10 in the radial direction.

[0045] like Figure 1 , Figure 2 and Figure 4 As shown, the other end 102 of the cuff body 10 passes through the first through hole H1 and overlaps with one end 101 of the cuff body 10. One end 201 of the air bag 20 in the circumferential direction passes through the second through hole H2 of the cuff body 10, and the other end 202 of the air bag 20 in the circumferential direction passes through the fourth through hole H4.

[0046] In this embodiment of the application, by providing a second through hole H2 and a fourth through hole H4, the air bag 20 passes through the second through hole H2 and the fourth through hole H4. A part of it is located on the radial inner side of the cuff body 10, and the other part is located on the radial outer side of the cuff body 10. This solves the problem of overlapping or wrinkling of air bags that may occur due to the overlapping arrangement of the cuff body 10.

[0047] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the other end 102 of the cuff body 10 is formed as a circumferentially penetrating receiving cavity C1. The receiving cavity C1 passes through the first through hole H1, and the fourth through hole H4 is adjacent to the receiving cavity C1 in the circumferential direction. That is, the fourth through hole H4 is located at the end E1 of the receiving cavity C1 away from the other end 102 of the cuff body 10. The receiving cavity C1 has a fifth through hole H5 that penetrates the cavity wall W in the radial direction on a part of the cavity wall W facing the cuff body 10.

[0048] Thus, by setting up the receiving cavity C1, one end 201 of the air bag 20 in the circumferential direction passes through the second through hole H2 and the fifth through hole H5 and is received in the receiving cavity C1, and the other end 202 of the air bag 20 in the circumferential direction passes through the fourth through hole H4 and is received in the receiving cavity C1. The first outlet end 103 of the end E1 of the air bag 20 in the circumferential direction, which is close to the other end 102 of the cuff body 10, is fixedly connected to the receiving cavity C1.

[0049] Figure 5 This is a schematic diagram of the cuff body 10 and the first fabric piece 30 according to an embodiment of the first aspect of this application, showing a fixed connection method between the cuff body 10 and the first fabric piece 30.

[0050] In the embodiments of this application, such as Figure 3 and Figure 5 As shown, one end 101 of the sleeve body 10 is also provided with a third through hole H3 located on the side of the end E2 near the first through hole H1 in the circumferential direction and penetrating the sleeve body 10 in the radial direction. The first fabric component 30 may include a first fabric component body 301, a first fabric component fixing part 302 fixedly connected to the first fabric component body 301, and a first fabric connecting part 303 passing through the third through hole H3 and connecting one end 3011 of the first fabric component body 301 in the circumferential direction and the first fabric component fixing part 302. That is, one end of the first fabric component 30 passes through the third through hole H3 and then through the third through hole H3. The part of the first fabric component 30 (i.e., the first fabric component fixing part 302) is, for example, sewn together with the first fabric component body 301 on the radial inner side of the first fabric component body 301, thereby realizing the fixed connection between one end of the first fabric component 30 and the sleeve body 10.

[0051] like Figure 5 As shown, the first fabric body 301 has a sixth through hole H6 that penetrates the first fabric 30 radially at a position approximately opposite to the first through hole H1.

[0052] like Figure 5 As shown, the other end 3012 of the first fabric body 301 in the circumferential direction is fixedly connected to the other end 102 of the sleeve body 10, thereby realizing the fixed connection between the other end of the first fabric 30 and the sleeve body 10. When the other end 102 of the sleeve body 10 is formed as a receiving cavity C1, the other end 3012 of the first fabric body 301 in the circumferential direction is fixedly connected to the first outlet end 103 of the receiving cavity C1.

[0053] In the embodiments of this application, it can be as follows Figure 5 As shown, the first fabric component 301 has two ends 3012 in the circumferential direction, which are connected to the radial inner and radial outer edges of the first outlet end 103, respectively. In this way, when the cuff body 10 is tightened by the first fabric component 30, the cuff body 10 can be pulled from both sides, making the force on the cuff body 10 more even. However, the implementation of this application is not limited to this. Alternatively, the other end 3012 of the first fabric component 301 in the circumferential direction can be connected to the radial inner or radial outer edge of the first outlet end 103, thereby achieving a fixed connection between the first fabric component 30 and the cuff body 10.

[0054] Figure 6 This is a schematic diagram of the cuff fastening part according to an embodiment of the first aspect of this application; Figure 7 This is a top view of the cuff fastening part according to an embodiment of the first aspect of this application; Figure 8 It is along Figure 7 A cross-sectional view of line A-A'.

[0055] In the embodiments of this application, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the cuff fastening part 40 may include a cuff fastening main body 401 that passes through the sixth through hole H6 in the radial direction, a cuff fastening connecting part 402 that is fixedly connected to the cuff fastening main body 401 and is disposed on the outside of the cuff fastening main body 401 in the circumferential direction, and a tightening cord 50 that passes through the cuff fastening main body 401. The cuff fastening connecting part 402 is fixedly connected to the first fabric piece 30; that is, the cuff fastening part 40 achieves a fixed connection with the first fabric piece 30 through the cuff fastening connecting part 402.

[0056] In the embodiments of this application, such as Figure 6As shown, the cuff fastening connection 402 can, for example, consist mainly of two parts: an upper connection portion 4021 located radially outward of the first fabric piece 30 and a lower connection portion 4022 located radially inward of the first fabric piece 30. The upper connection portion 4021 and the lower connection portion 4022 are used to clamp the first fabric piece 30; additionally, as... Figure 6 and Figure 7 As shown, the cuff fastening connection part 402 may also include four fixing posts 4023. Correspondingly, holes corresponding to the four fixing posts 4023 can be provided on the first fabric part 30 to further facilitate the fixing of the first fabric part 30.

[0057] In the embodiments of this application, such as Figure 1 , Figure 6 and Figure 8 As shown, the cuff fastening body 401 is provided with a seventh through hole H7 that runs through the cuff fastening body 401 in the circumferential direction. The tightening rope 50 passes through the seventh through hole H7 of the cuff fastening body 401, and the two ends 501 and 502 of the tightening rope 50 are respectively fixedly connected to the first fabric piece 30.

[0058] In this embodiment, the cuff fastening main body 401 and the cuff fastening connecting part 402 can be fixedly connected in any way, such as by bonding. The fixed connection between the tightening cord 50 and the first fabric piece 30 can also be achieved in any way, such as by sewing or splicing.

[0059] like Figure 6 and Figure 8 As shown, the cuff fastening main body 401 may include a hand handle 4011, a first engaging part 4012 integrally formed with the hand handle 4011, and a second engaging part 4013 engaged with the first engaging part 4012.

[0060] Before blood pressure measurement, when the user needs to tighten the cuff body 10, they can rotate the hand lever 4011 with one hand. The tightening cord 50, passing through the seventh through-hole H7, will wrap around the hand lever 4011 as it rotates, thereby tightening the cuff body 10 by moving the first fabric piece 30. When the user feels the cuff body 10 is at the appropriate tightness, they can stop rotating the hand lever 4011. At this point, the first locking part 4012 and the second locking part 4013 will engage to prevent the hand lever 4011 from rotating backward. After blood pressure measurement, when the user needs to loosen the cuff body 10, they can press the hand lever 4011 with one hand. This will disengage the first locking part 4012 and the second locking part 4013, allowing the hand lever 4011 to rotate backward, loosening the tightening cord 50, and thus releasing the first fabric piece 30, allowing the cuff body 10 to be released from the arm.

[0061] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the adaptive sleeve 1 may also include a first elastic fabric member 60, which is disposed on the radial outer side of the sleeve body 10, and its two circumferential ends are respectively fixedly connected to one end 3011 and the other end 3012 of the first fabric member body 301 in the circumferential direction.

[0062] By setting the first elastic fabric piece 60, it can be ensured that when adjusting the inner diameter of the sleeve body 10 to accommodate users with different arm circumferences, the first fabric piece 30 will not wrinkle to a large extent, thus preventing pinching of the skin and affecting the user experience.

[0063] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the adaptive sleeve 1 may further include a third fabric piece 80, which is disposed radially inside the sleeve body. The axial ends of the third fabric piece 80 are fixedly connected to the first fabric piece 30 at the axial ends of the sleeve body 10, respectively. In other words, the positioning of the third fabric piece 80 is achieved by fixing its axial ends to the first fabric piece 30 (e.g., by sewing or splicing).

[0064] By setting a third fabric piece 80, it can be used to isolate the user's arm from the second fabric piece 70, thereby protecting the second fabric piece 70 and the air bag 20.

[0065] In the embodiments of this application, such as Figure 1 As shown, the adaptive sleeve 1 may further include a second elastic fabric member 90, which is disposed radially inside the sleeve body 10. Its circumferential ends (one end 901 and the other end 902) are respectively fixedly connected to the circumferential ends (one end 801 and the other end 802) of the third fabric member 80. Additionally, the axial ends of the second elastic fabric member 90 may also be fixedly connected to the first fabric member 30 and the third fabric member 80 at the axial ends of the sleeve body 10, respectively.

[0066] By setting a second elastic fabric piece 90, the third fabric piece 80 can be protected to keep the sleeve body 10 as flat as possible during the tightening process, so as not to generate wrinkles to a large extent, prevent pinching the skin and affect the user experience.

[0067] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the adaptive sleeve 1 may further include a second fabric member 70. A portion of the second fabric member 70 is disposed on the radial inner side of the sleeve body 10. One end of the second fabric member 70 in the circumferential direction passes through the second through hole H2, and the other end of the second fabric member 70 in the circumferential direction passes through the fourth through hole H4. The two ends of the second fabric member 70 in the circumferential direction are fixedly connected to the sleeve body 10.

[0068] Based on the aforementioned placement of the airbag 20, it can be seen that the second fabric component 70 is positioned in the same way as the airbag 20. Therefore, by providing the second fabric component 70, the airbag 20 can be protected.

[0069] like Figure 1 and Figure 4 As shown, when the other end 102 of the cuff body 10 forms a receiving cavity C1, one end of the second fabric member 70 in the circumferential direction passes through the second through hole H2 and the fifth through hole H5 and is received in the receiving cavity C1. The other end of the second fabric member 70 in the circumferential direction passes through the fourth through hole H4 and is received in the receiving cavity C1. The circumferential end of the second fabric member 70 and the other end are fixedly connected to the receiving cavity C1 at the first outlet end 103. In this embodiment, the two axial ends of the third fabric member 80 can also be fixedly connected to the second fabric member 70 at the two axial ends of the cuff body 10, that is, the third fabric member 80 is fixedly connected to the second fabric member 70 through its two axial ends; in addition, the two axial ends of the second elastic fabric member 90 can also be fixedly connected to the second fabric member 70 at the two axial ends of the cuff body 10.

[0070] In the embodiments of this application, such as Figure 1 and Figure 4 As shown, the adaptive sleeve 1 may also include a fourth fabric piece 100, which is disposed on the radial outer side of the sleeve body 10 and is located radially between the first fabric piece 30 and the sleeve fastening part 40; the two circumferential ends of the fourth fabric piece 100 (one end 1001 and the other end 1002 in the circumferential direction) are respectively fixedly connected to the first fabric piece 30.

[0071] By providing a fourth fabric piece 100, it can be used to isolate the cuff body 10 and the cuff fastening part 40, preventing friction between the two.

[0072] In the embodiments of this application, such as Figure 2 As shown, the second through hole H2, the fourth through hole H4 and the fifth through hole H5 are provided with anti-pressure dead parts 104 extending from the through hole wall at the positions through which the air bag 20 passes (e.g., P1, P2, P3, P4). (For example, an anti-pressure dead part 104 is provided at position P1 of the second through hole H2, at positions P2 and P3 of the fourth through hole H4, and at position P4 of the fifth through hole H5).

[0073] By setting anti-compression parts 104 between the stress points (positions P1, P2, P3, P4) where the air bag and the cuff body 10 come into contact, the air bag 20 can be prevented from being excessively compressed at these positions, thus avoiding the normal inflation of the air bag 20 during the blood pressure measurement process and protecting the air bag 20.

[0074] In the embodiments of this application, such as Figure 2 As shown, the anti-pressure dead portion 104 can be a roller structure; that is, rollers extend from the through-hole walls of the second through-hole H2, the fourth through-hole H4, and the fifth through-hole H5, respectively, thereby preventing the air bag 20 from being excessively compressed. However, in this embodiment, the anti-pressure dead portion 104 is not limited to a roller structure, but can also be other structures to prevent the air bag 20 from being excessively compressed. For example, the edges of the second through-hole H2, the fourth through-hole H4, and the fifth through-hole H5 can be chamfered, etc.

[0075] According to the adaptive cuff 1 of this application embodiment, by designing the cuff body 10 as a self-intersecting ring structure and by setting a first fabric piece 30 fixedly connected to the cuff body 10 and a cuff fastening part 40 fixedly connected to the first fabric piece 30, the user can quickly and conveniently complete a series of actions such as putting on the cuff, adjusting the tightness, and taking off the cuff with one hand, thereby improving the convenience of operation; and since the first fabric piece 30 and the cuff fastening part 40 are used to tighten and fasten the cuff, no noise will be generated during the measurement process, which will affect the measurement accuracy of blood pressure, thereby improving the accuracy of blood pressure measurement.
