[0048] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0049] Please see Figures 1 to 3As shown, this application embodiment provides a dual-purpose dynamic blood pressure monitor 900, which includes a first cuff assembly 6, a second cuff assembly 7, a main unit 5, and a carrying case 4. The first cuff assembly 6 includes a first cuff 61 and a first trachea 63 connected together, and the second cuff assembly 7 includes a second cuff 71 and a second trachea 73 connected together, wherein the length of the first trachea 63 is shorter than the length of the second trachea 73. The main unit 5 can be detachably connected and communicated with the end of either the first trachea 63 or the second trachea 73. The main unit 5 can also be connected to at least the outer surface of the first cuff 61 to be fixed to the outer surface of the first cuff 61. The carrying case 4 is used to accommodate at least a portion of the main unit 5.

[0050] The dual-purpose ambulatory blood pressure monitor 900 provided in this application embodiment is used as follows:

[0051] In the first mode of use, at least a portion of the main unit 5 is housed within the carrying case 4, and the main unit 5 is connected and communicates with the end of the second air tube 73. Please refer to [link / reference needed]. Figure 2 As shown. At this point, the second ambulatory blood pressure monitor 200 is composed of at least the main unit 5, the carrying case 4, and the second cuff assembly 7.

[0052] In the second usage mode, the main unit 5 is connected to the outer surface of the first cuff 61 and the main unit 5 is connected and communicated with the end of the first air tube 63. Please refer to [link / reference]. Figure 3 As shown. At this time, the main unit 5 is fixed to the outer surface of the first cuff 61. The first dynamic blood pressure monitor 100 is composed of at least the main unit 5 and the first cuff assembly 6.

[0053] In the second cuff assembly 7 and the second cuff assembly 7, all the parts are the same except that the length of the first trachea 63 is less than the length of the second trachea 73.

[0054] In the second usage mode, the length of the first tubing 63 is shorter, adapting to the distance between the main unit 5 and the first cuff 61. In this mode, the first dynamic blood pressure monitor 100 can be fixed to the user's upper arm. In the first usage mode, the length of the second tubing 73 is longer, allowing the main unit 5 and carrying case 4 to be used away from the second cuff 71. Specifically, the main unit 5 and carrying case 4 can be positioned on the user's chest, side, back, etc. In this mode, the second cuff 71 is fixed to the user's upper arm, and its thinness prevents it from interfering with the user's daily life. Furthermore, the thinness of the second cuff 71 allows the user to wear clothing over it.

[0055] The dual-purpose ambulatory blood pressure monitor 900 provided in this application embodiment includes a first cuff assembly 6 and a second cuff assembly 7 with different tracheal lengths. The main unit 5 can be detachably connected to both the first cuff assembly 6 and the second cuff assembly 7, allowing it to be used either fixed to the first cuff assembly 6 or placed inside a carrying case 4 away from the second cuff assembly 7. This meets different user needs and reduces disruption to daily life. For hospitals, rehabilitation centers, etc., this dual-purpose ambulatory blood pressure monitor 900 has a higher turnover rate, improving equipment efficiency and saving costs.

[0056] Please see Figure 1 As shown, in one embodiment, the first cuff assembly 6 and the second cuff assembly 7 each include a first connector 64, which is connected to the end of the first air tube 63 (the end opposite to the first cuff 61) and the end of the second air tube 73 (the end opposite to the second cuff 71). The main unit 5 includes a second connector 55, and any first connector 64 can be at least partially inserted into the second connector 55 and is in sealed communication with the second connector 55.

[0057] Please see Figure 4 and Figure 5 As shown, the detachable connection between the second connector 55 and the first connector 64 of the host 5 will be introduced first.

[0058] In one embodiment, such as Figure 4 and Figure 5 As shown, the first connector 64 includes a first connecting section 641, which can be inserted into the second connector 55 and is in sealed communication with the second connector 55, and can be detached from the second connector 55.

[0059] like Figure 4 and Figure 5 As shown, in one embodiment, the first connector 64 further includes an annular abutment 642 disposed on the side of the first connecting section 641 facing away from the first connector 64; the annular abutment 642 is located outside the second connector 55.

[0060] The outer dimension of the annular abutment 642 is larger than the dimension of the first connecting segment 641, thereby allowing the annular abutment 642 to shield the first connecting segment 641 and the second connector 55. In an optional embodiment, the side of the second connector 55 facing the first connector 64 is flush with the surface of the housing 51 of the host 5, and the annular abutment 642 abuts against the surface of the housing 51 of the host 5. This arrangement aims to ensure, on the one hand, the uniformity of the surface appearance of the housing 51, and on the other hand, the abutment 642 against the surface of the housing 51 of the host 5, which limits the wobbling of the first connector 64 relative to the second connector 55, thereby ensuring a stable connection between the first connector 64 and the second connector 55 and maintaining a reliable sealing connection.

[0061] Please continue reading. Figure 4 and Figure 5 As shown, in one embodiment, the first connector 64 further includes a second connecting section 643, which is disposed on the side of the annular abutment 642 opposite to the first connecting section 641; the second connecting section 643 is located inside the ends of the first air tube 63 and the second air tube 73 respectively, and is sealed to the inner wall surfaces of the first air tube 63 and the second air tube 73.

[0062] The connection method between the second connecting section 643 and the first air pipe 63 and the second air pipe 73 is not limited. For example, it can be bonding, welding, etc., as long as the outer peripheral wall of the second connecting section 643 and the inner peripheral wall of the end of the first air pipe 63 and the second air pipe 73 can be sealed.

[0063] The second connector 55 and the first connecting section 641 of the first connector 64 are detachably and sealingly connected. Specifically, as shown in... Figure 4 and Figure 5 As shown, the second connector 55 includes a connector body 551; wherein, at least one of the inner wall of the connector body 551 and the outer peripheral surface of the first connecting segment 641 is provided with a limiting protrusion 552, and the other of the inner wall of the connector body 551 and the outer peripheral surface of the first connecting segment 641 is provided with a corresponding first limiting groove 6410. The first connector 64 can be at least partially inserted into the first connecting segment 641, and the limiting protrusion 552 is located within the first limiting groove 6410. When the limiting protrusion 552 is located within the first limiting groove 6410, the first connector 64 is restricted in the insertion / removal direction and cannot detach from the second connector 55; when the user applies a force to the first connector 64 away from the second connector 55, the limiting protrusion 552 can disengage from the first limiting groove 6410, and the first connecting segment 641 of the first connector 64 can detach from the second connector 55. Thus, a detachable connection between the second connector 55 and the first connector 64 is achieved. The insertion / removal direction of the first connector 64 can be the axial direction of the second connector 55 and the first connector 64.

[0064] In this embodiment, the first connector 64 and the second connector 55 of the main unit 5 are detachably connected by radial engagement between the limiting protrusion 552 and the first limiting groove 6410. The second connector 55 and the first connector 64 can be inserted and removed axially, making connection and disassembly simple and not increasing the difficulty or complexity of the operation. Simultaneously, the main unit 5 is detachably connected to the trachea (first trachea 63, second trachea 73), allowing the main unit 5 to connect and communicate with cuff assemblies (first cuff assembly 6, second cuff assembly 7) with trachea of ​​different lengths, thus forming a first ambulatory blood pressure monitor 100 and a second ambulatory blood pressure monitor 200 with different usage modes.

[0065] When the first connecting segment 641 is located inside the second connector 55, the outer surface of the first connecting segment 641 (specifically, the outer peripheral wall of the first connecting segment 641, and / or the end face of the first connecting segment 641 facing away from the second connecting segment 643) is sealed to the inner wall surface of the second connector 55.

[0066] In one embodiment of this application, please refer to Figure 4 and Figure 5 As shown, the limiting protrusion 552 is provided on the inner wall of the connector body 551. The first limiting groove 6410 is provided on the outer peripheral surface of the first connecting section 641.

[0067] Please see Figure 4 and Figure 5 As shown, in one embodiment, there are multiple limiting protrusions 552, and these protrusions are spaced apart along the inner wall of the connector body 551. Optionally, the multiple limiting protrusions 552 are evenly spaced along the inner wall of the connector body 551. For example, there are three limiting protrusions 552, spaced apart at 120° central angles; or four limiting protrusions 552, spaced apart at 90° central angles. In other embodiments, the number of limiting protrusions 552 can be any number, as long as they can form a stable fit with the first limiting groove 6410.

[0068] The number of first limiting grooves 6410 corresponds to the number of limiting protrusions 552. In one embodiment, multiple first limiting grooves 6410 are spaced apart on the outer peripheral wall of the first connecting segment 641. Alternatively, as... Figure 4 As shown, in one embodiment of this application, a plurality of first limiting grooves 6410 are continuously distributed on the outer peripheral wall of the first connecting section 641. That is to say, the first limiting grooves 6410 are in a continuous closed ring shape, and there is no obvious dividing line between the plurality of first limiting grooves 6410. The purpose of this arrangement is, on the one hand, to facilitate the processing and manufacturing of the first limiting grooves 6410, and on the other hand, to enable the first connecting section 641 to be inserted and removed from the second connector 55 in any direction of 360°.

[0069] Please see Figure 5 As shown, in one embodiment, the second connector 55 further includes a reset member 553, which is disposed on the side of the limiting protrusion 552 that is radially away from the first limiting groove 6410 along the second connector 55. The reset member 553 is used to provide a radial force to the limiting protrusion 552 toward the first limiting groove 6410, so that the limiting protrusion 552 is held within the first limiting groove 6410.

[0070] The reset component 553 can be a compression spring, or it can be in the form of an elastic material pad, an elastic material column, etc.

[0071] Please continue reading. Figure 5 As shown, in one embodiment, the inner wall of the connector body 551 is recessed radially outward with a receiving hole 5510. The receiving hole 5510 forms a communication opening 5511 on the inner wall surface of the connector body 551. The size of the communication opening 5511 is smaller than the outer size of the limiting protrusion 552, and the inner size of the receiving hole 5510 is larger than the outer size of the limiting protrusion 552, so that a part of the limiting protrusion 552 can be exposed through the communication opening 5511, while the other part is restricted by the communication opening 5511 and cannot be exposed. The reset member 553 is disposed in the receiving hole 5510 and located on the side of the limiting protrusion 552 opposite to the communication opening 5511.

[0072] Please see Figure 5 As shown, in one embodiment, the limiting protrusion 552 has a smoothly transitioned outer surface. The purpose of this design is that when the limiting protrusion 552 needs to disengage from the first limiting groove 6410, the smoothly transitioned outer surface provides a certain guiding effect, making it easier for the limiting protrusion 552 to disengage.

[0073] Please see Figure 5 As shown, in one embodiment, the first limiting groove 6410 has two limiting surfaces 6411 connected axially along the first connector 64. The limiting surfaces 6411 are smoothly transitioned curved surfaces or inclined surfaces. The purpose of this arrangement is that the limiting surfaces 6411 can also provide a guiding effect for the axial sliding of the limiting protrusion 552, making it easy for the limiting protrusion 552 to disengage from the first limiting groove 6410.

[0074] In one specific embodiment of the application, such as Figure 5 As shown, the limiting protrusion 552 has a smoothly transitioned outer surface, and the limiting surface 6411 is a smoothly transitioned curved surface or an inclined surface. More specifically, the limiting protrusion 552 is a sphere, and less than half of the limiting protrusion 552 can be exposed through the connecting port 5511. The limiting surface 6411 is an inclined surface that is substantially mirror-symmetrical about the radial plane of the first connector 64. This facilitates the manufacturing of the limiting protrusion 552 and the first limiting groove 6410.

[0075] As mentioned earlier, the second connector 55 is sealed to the first connecting section 641, such as... Figure 5 As shown, in one embodiment, the second connector 55 further includes at least one sealing ring 554, which is fixedly disposed on the inner wall of the connector body 551 and is sealed to the outer surface of the first connecting section 641 of the first connector 64. Optionally, as shown... Figure 5As shown, the inner wall of the connector body 551 is also provided with an annular mounting groove 5512. A portion of the sealing ring 554 is fixedly disposed in the mounting groove 5512 by, for example, an interference fit, while the other portion protrudes from the inner wall surface of the connector body 551. The outer peripheral surface of the first connecting section 641 and / or the end face facing away from the second connecting section 643 abut against the sealing ring 554 and press the sealing ring 554 tightly.

[0076] Depending on the sealing requirements, the number of mounting grooves 5512 and sealing rings 554 can be multiple. For example, see... Figure 5 As shown, the inner wall of the connector body 551 includes a stepped surface 5513 opposite to the end face of the first connector 64 facing away from the second connecting segment 643. This stepped surface 5513 abuts against the end face of the first connector 64 facing away from the second connecting segment 643 to limit the insertion length of the first connector 64 into the second connector 55. In one embodiment of this application, a mounting groove 5512 and a sealing ring 554 are disposed on the inner peripheral wall of the connector body 551, and another mounting groove 5512 and another sealing ring 554 are disposed on the stepped surface 5513 of the connector body 551. The two sealing rings 554 abut against the outer peripheral surface of the first connecting segment 641 and the end face of the first connecting segment 641 facing away from the second connecting segment 643, respectively. In other optional embodiments, the number of mounting grooves 5512 and sealing rings 554 can be different, and their positions can be correspondingly disposed on the stepped surface 5513 and / or the inner peripheral wall of the connector body 551.

[0077] Next, the first ambulatory blood pressure monitor 100 of this application will be introduced. It is understood that the first ambulatory blood pressure monitor 100 is a fully functional, stand-alone ambulatory blood pressure monitor.

[0078] like Figure 3 As shown, the first cuff assembly 6 also includes a first airbag 62 disposed within the first cuff 61, the first airbag 62 being able to wrap around the user's upper arm along with the first cuff 61. Figure 1 As shown, the main unit 5 includes a housing 51, and an air pump and a pressure sensor (neither shown) disposed within the housing 51. The air pump is connected to the first airbag 62 via a first air tube 63, and is used to inflate and deflate the first airbag 62. The pressure sensor is used to detect the pressure within the first air tube 63 and the first airbag 62. After the first airbag 62 is inflated, it can apply pressure to the user's upper arm. The pressure sensor can sense changes in pressure within the first airbag 62 and convert them into electrical signals.

[0079] The first sleeve 61 has a multi-layered fabric structure. The first airbag 62 is positioned between two adjacent layers of fabric.

[0080] The main unit 5 also includes a control component (not shown) located within the housing 51. The control component is communicatively connected to the pressure sensor. The control component can acquire the electrical signals from the pressure sensor and store and process the relevant electrical signals for user use. For example, the control component can interact with the control center via methods such as Bluetooth, Wi-Fi, or 4G mobile communication to upload relevant data to the control center.

[0081] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the host 5 further includes at least one button 57. The button 57 is disposed on the housing 51 and connected to the control component. The user can input operation information to the control component through the button 57. The button 57 can be one or more of a power button, start button, pause button, etc. Depending on the design requirements, multiple buttons 57 can be arranged separately on the housing 51 or integrated, as long as it is convenient for user operation.

[0082] like Figures 1 to 3 As shown, the main unit 5 also includes a display screen 56, which is mounted on the housing 51 and is communicatively connected to the control component. The control component is used to display relevant information during the measurement process on the display screen 56 in real time, so that users can obtain relevant detection information in real time.

[0083] Please see Figure 1 , Figure 6 and Figure 7 As shown, in one embodiment, the outer shell 51 includes a first shell portion 511 and a second shell portion 512 connected along the thickness direction of the first cuff 61, the second shell portion 512 being located on the side of the first shell portion 511 opposite to the first cuff 61.

[0084] Please see Figure 3 and Figure 6 , Figure 7 As shown, in the first dynamic blood pressure monitor 100 of this application embodiment, the first cuff assembly 6 can be connected to the housing 51 of the host 5. Specifically, the first cuff assembly 6 and the housing 51 are detachably connected.

[0085] The purpose of this design is that the first cuff 61 of the first cuff assembly 6 is detachably connected to the outer shell 51 of the main unit 5. When the user wears the first cuff assembly 6, the main unit 5 can be detached from the first cuff 61 and temporarily placed on a surface such as a table. At this time, the weight of the main unit 5 will not be superimposed on the first cuff 61. The first cuff 61 is relatively light and evenly distributed, making it convenient for the user to wear, especially when the user needs to wear it with one hand. After the first cuff 61 is successfully worn, the main unit 5 can be fixed to the outer surface of the first cuff 61.

[0086] In one embodiment, the first cuff 61 is detachably connected to the main unit 5 via Velcro (not shown). For example, the outer surface of the first cuff 61 is provided with a hook side of Velcro, and the bottom of the housing 51 of the main unit 5 (the side facing the first cuff 61) is provided with a loop side of Velcro. By the cooperation of the loop side and the hook side, the main unit 5 can be fixed to the outer surface of the first cuff 61.

[0087] In one embodiment, please refer to Figure 6 , Figure 7 As shown, the first dynamic blood pressure monitor 100 also includes a latching assembly 8, which includes a latch 83 and a base 81. One of the latch 83 and the base 81 is located at the bottom of the housing 51 of the main unit 5, and the other is located on the outer surface of the first cuff 61. The detachable connection between the main unit 5 and the first cuff assembly 6 is achieved through the detachable connection between the latch 83 and the base 81.

[0088] In other embodiments, the first cuff assembly 6 and the main unit 5 can be detachably connected in other ways. For example, the first cuff assembly 6 and the main unit 5 can be detachably connected by mutual magnetic attraction.

[0089] The buckle component 8 of this application embodiment is described in detail.

[0090] The buckle assembly 8 is disposed between the main unit 5 and the first cuff 61 of the first cuff assembly 6. In other words, the buckle assembly 8 is disposed between the first cuff 61 and the main unit 5 along the thickness direction of the first cuff 61. For ease of understanding, the opposite surfaces of the buckle 83 and the base 81 are respectively used as their bottom surfaces, i.e., please refer to [reference needed]. Figure 6 ,and Figure 10 As shown, the side of the base 81 facing away from the buckle 83 serves as its bottom surface, here defined as the first bottom surface 810, which is used to connect with the first cuff 61; please refer to Figure 9 As shown, the side surface of the buckle 83 facing away from the base 81 serves as its bottom surface, which is defined here as the second bottom surface 830. The second bottom surface 830 is used to connect with the housing 51 of the main unit 5.

[0091] Please see Figure 6 and Figure 10 As shown, in one embodiment, the base 81 includes a base body 811 and a baffle 812. The base body 811 is used to be fixedly connected to the first cuff 61, specifically the outer surface of the first cuff 61. The first bottom surface 810 is the side surface of the base body 811 that is away from the host 5.

[0092] like Figure 6 , Figure 8As shown, a second limiting groove 814 is provided on the side of the baffle 812 facing the first bottom surface 810. That is, the baffle 812 protrudes from the base body 811 and is suspended relative to the base body 811 to form the second limiting groove 814; Figure 6 , Figure 7 and Figure 10 As shown, a groove 813 is formed between at least one surface of the baffle 812 and the base body 811. The opening direction (extension direction) of the groove 813 is perpendicular to the thickness direction of the first cuff 61. At least one end of the groove 813 has an opening 8130, and a first limiting portion 815 is provided on at least one inner sidewall of the groove 813 (i.e., on at least one surface of the baffle 812). Figure 6 and Figure 9 As shown, the buckle 83 includes a sliding portion 831 and a second limiting portion 833 connected to the side of the sliding portion 831 facing away from the second bottom surface 830. At least one side surface of the sliding portion 831 is provided with a first mating portion 832. The sliding portion 831 can enter the slide groove 813 through the opening 8130, and the first limiting portion 815 is connected to the first mating portion 832. Figure 7 and Figure 8 As shown, the second limiting part 833 is located in the second limiting groove 814, the sliding part 831 is located in the sliding groove 813, and the first limiting part 815 is connected to the first mating part 832.

[0093] One of the first limiting part 815 and the first mating part 832 is a groove, and the other is a protrusion that mates with the groove.

[0094] Therefore, in the thickness direction of the first cuff 61, the second limiting part 833 is located on the side of the baffle 812 facing the first bottom surface 810. In the thickness direction of the first cuff 61, the buckle 83 and its second limiting part 833 are restricted and cannot cross the baffle 812 to disengage from the base 81. In the extension direction of the slide groove 813, the first limiting part 815 is restricted by the first mating part 832 and cannot move along the slide groove 813 towards its opening 8130. The buckle 83 and its sliding part 831 are restricted and cannot disengage from the slide groove 813. At this time, the buckle 83 forms a stable connection with the base 81.

[0095] Conversely, when a force is applied to the buckle 83 along the extension direction of the slide groove 813 and toward the opening 8130, the first limiting part 815 can be pushed away from the first mating part 832, the sliding part 831 moves toward the opening 8130, and the buckle 83 is removed from the base 81.

[0096] In this embodiment, the extension direction of the groove 813 is perpendicular to the thickness direction of the first cuff 61. Therefore, the user operates the main unit 5 in a direction perpendicular to the thickness direction of the first cuff 61. When the user wears the first cuff 61 and installs the main unit 5, the upper arm is usually horizontal or nearly horizontal (with a small downward tilt). At this time, the user's operation direction on the main unit 5 is generally horizontal or nearly horizontal, which conforms to the user's operating habits. Furthermore, the user's force is not applied perpendicularly to the first cuff 61 and the user's upper arm. That is, the operation will not cause pressure on the user's upper arm, and the user's upper arm does not need to provide a reaction force but can remain relaxed, thus improving the user's wearing experience.

[0097] In one embodiment of this application, such as Figure 1 As shown, the base 81 is mounted on the first cuff 61, as... Figure 6 , Figure 7 and Figure 8 As shown, the buckle 83 is disposed on the outer casing 51 of the main unit 5, specifically on the first housing portion 511. The side surface of the base 81 facing the first cuff 61 serves as its first bottom surface 810, which is used to fixably connect with the outer surface of the first cuff 61. The side surface of the buckle 83 facing the main unit 5 serves as its second bottom surface 830, which is used to fixably connect with the bottom of the outer casing 51 of the main unit 5.

[0098] Please see Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment, the base 81 includes two opposing and spaced-apart baffles 812, a groove 813 formed between the two baffles 812, and opposite sides of the two baffles 812 for connection with the base body 811. Accordingly, please refer to... Figure 6 and Figure 9 As shown, the second limiting part 833 includes sub-limiting parts 8330 located on opposite sides of the sliding part 831, and each sub-limiting part 8330 is located on the side of a baffle 812 facing the first bottom surface 810.

[0099] To ensure that the second limiting part 833 can smoothly enter the second limiting groove 814, the depth of the second limiting groove 814 needs to be greater than or equal to the thickness of the second limiting part 833. In practical applications, the depth of the second limiting groove 814 is generally slightly greater than the thickness of the second limiting part 833. Therefore, in the thickness direction, there will be a certain gap on the side of the second limiting part 833 facing the baffle 812 and / or the side away from the baffle 812, which may cause the second limiting part 833 to wobble. In the embodiments of this application, the two sub-limiting parts 8330 of the second limiting part 833 are respectively located on the side of the baffle 812 facing the first bottom surface 810. This makes the cooperation between the second limiting part 833 and the baffle 812 more balanced, and avoids the second limiting part 833 from being tilted relative to the baffle 812 in the second limiting groove 814, which would affect the cooperation between the protrusion and the groove.

[0100] Please see Figure 6 and Figure 10 As shown, in one embodiment, the first limiting portion 815 is a protrusion. See also... Figure 7 and Figure 9 As shown, the second limiting part 833 is a groove. Specifically, each of the two baffles 812 has a protrusion on its adjacent side surface, and the sliding part 831 has grooves on its opposite sides. In other optional embodiments, the grooves may be provided on the adjacent side surface of the two baffles 812, and the protrusions may be provided on the opposite sides of the sliding part 831.

[0101] Please continue reading. Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment, both adjacent surfaces of the two baffles 812 are provided with protrusions, and each baffle 812 has a through hole 8120 extending along its thickness direction. The through hole 8120 is aligned with the protrusion in its protruding direction. This arrangement allows the through hole 8120 to provide elasticity to the area on the baffle 812 with the protrusion, meaning the protruding area can elastically deform towards the through hole 8120. This allows the protrusion to easily slide into the groove.

[0102] In the embodiments of this application, the baffle 812 has a large width and area, which facilitates the machining of protrusions and through holes 8120 on the baffle 812. As a result, the width of the sliding portion 831 can be set to be smaller.

[0103] Please see Figure 8 and Figure 10As shown, in one embodiment, the base body 811 has a guide groove 816 recessed on its surface opposite to the first bottom surface 810. The guide groove 816 communicates with the second limiting groove 814 in the extending direction of the slide groove 813, and the guide groove 816 is located on the side of the slide groove 813 with the opening 8130. The size of the guide groove 816 is larger than the size of the second limiting part 833, so as to allow the second limiting part 833 to enter the guide groove 816 along the thickness direction of the first cuff 61. After the second limiting part 833 enters the guide groove 816, it can further enter the second limiting groove 814 along the extending direction of the slide groove 813.

[0104] The purpose of this design is that when it is necessary to connect the buckle 83 to the base 81, the user can first align the second limiting part 833 with the guide groove 816 in the thickness direction of the first cuff 61, and then push the buckle 83 along the extension direction of the slide groove 813. This eliminates the need for the user to align the sliding part 831 with the opening 8130 of the slide groove 813. Instead, the larger second limiting part 833 and the larger guide groove 816 can be aligned along the thickness direction of the first cuff 61, resulting in higher alignment efficiency and making it easier to position the sliding part 831 and the slide groove 813.

[0105] Please see Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, in one embodiment, the base 81 further includes a stop 817, which is lower than the baffle 812 in the depth direction of the guide groove 816. The stop 817 defines the inner bottom wall of the guide groove 816. The inner bottom wall of the guide groove 816 forms a stop for the second limiting part 833, or in other words, the stop 817 positions the second limiting part 833 in the thickness direction of the first cuff 61.

[0106] When the second limiting part 833 abuts against the inner bottom wall of the guide groove 816 in the thickness direction of the first cuff 61, it indicates that the second limiting part 833 is inserted into the guide groove 816. At this time, the buckle 83 can be pushed flat towards the second limiting groove 814.

[0107] Please see Figure 6 and Figure 9As shown, the width of the second limiting part 833 gradually decreases from one end, specifically in the sliding direction of the second limiting part 833 (with the first cuff 61 as a reference, the base 81 remains stationary). This design ensures that when the second limiting part 833 is located within the guide groove 816, the narrower end of the second limiting part 833 is closer to the second limiting groove 814 and can align with the center of the width direction of the second limiting groove 814. At this time, pushing the buckle 83 allows the narrower end of the second limiting part 833 to align with and smoothly enter the second limiting groove 814. Consequently, the entire second limiting part 833 can smoothly enter the second limiting groove 814. Simultaneously, the sliding part 831 can align with and smoothly enter the sliding groove 813. Even if the user applies force at a slight angle relative to the extension direction of the sliding groove 813 when pushing the buckle 83, it does not affect the fit between the buckle 83 and the base 81.

[0108] like Figure 6 As shown, in one embodiment, the sliding portion 831 and the second limiting portion 833 are integrally formed with at least a portion of the outer shell 51 of the main unit 5. Specifically, the sliding portion 831 and the second limiting portion 833 are integrally formed with the first shell portion 511. For example, the sliding portion 831, the second limiting portion 833, and the first shell portion 511 are manufactured by integral injection molding.

[0109] It is understandable that the sliding part 831 and the first housing part 511 are manufactured by integral injection molding. Therefore, the second bottom surface 830 of the buckle 83 is not actually visible from the outside. The second bottom surface 830 can be a virtual interface between the sliding part 831 and the first housing. (See [reference]) Figure 9 The surface shown in the middle is a cross-section.

[0110] In other alternative embodiments, the sliding part 831, the second limiting part 833, and the first housing part 511 can be fixedly connected together by other means, such as welding. As long as the buckle 83 and the housing 51 can be securely connected, it is acceptable.

[0111] Please see Figure 6 , Figure 7 and Figure 8 As shown, in one embodiment, the buckle assembly 8 further includes a mounting plate 85 and a fastener 86. The mounting plate 85 is disposed inside the first sleeve 61, and the fastener 86 passes through at least one fabric layer of the first sleeve 61 and fixes the mounting plate 85 and the base 81.

[0112] For example, on the outside of the first airbag 62, the first cuff 61 includes at least two fabric layers. The mounting plate 85 can be disposed between two adjacent fabric layers. Fasteners 86 pass through the mounting plate 85 and at least one fabric layer in sequence, and then connect to the base body 811 of the base 81. Thus, the base 81 can be fixed to the first cuff 61.

[0113] In other alternative embodiments, the base 81 may be attached to the first cuff 61 in other ways, such as by adhesive.

[0114] Please see Figure 6 , Figure 8 As shown, in one embodiment, the mounting plate 85 has a recessed clearance groove 850 along the thickness direction of the first sleeve 61 from the side facing the base 81; please refer to the reference. Figure 10 As shown, the base 81 has an annular retaining wall 818 protruding from its first bottom surface 810 on the side facing the mounting plate 85, and the annular retaining wall 818 is located within the clearance groove 850. At least one fabric layer of the first sleeve 61 is sandwiched between the outer peripheral wall of the annular retaining wall 818 and the inner peripheral wall of the clearance groove 850. The purpose of this arrangement is to increase the contact area between the fabric layer of the first sleeve 61 and the base 81 and the mounting plate 85, thereby increasing the friction between the fabric layer of the first sleeve 61 and the base 81 and the mounting plate 85. Furthermore, the fabric layer of the first sleeve 61 will form wrinkles between the annular retaining wall 818 and the clearance groove 850, further increasing the friction between the fabric layer of the first sleeve 61 and the base 81 and the mounting plate 85, ensuring the stable installation of the base 81 and the mounting plate 85 relative to the first sleeve 61.

[0115] In one alternative embodiment, such as Figure 6 As shown, the clearance groove 850 on the mounting plate 85 is a through hole along the thickness direction of the first sleeve 61. The purpose of this design is to facilitate the processing and manufacturing of the mounting plate 85 and reduce production costs.

[0116] In one embodiment, such as Figure 6 and Figure 10 As shown, at least a portion of the second limiting groove 814 and guide groove 816 are formed within the annular retaining wall 818 in the thickness direction of the first cuff 61. The purpose of this arrangement is to utilize the space within the annular retaining wall 818, thereby reducing the overall thickness of the base 81. Specifically, as... Figure 10 As shown, the side of the base 81 opposite to its first bottom surface 810 is a plane, that is, the surfaces of the baffle 812 and the base body 811 opposite to the mounting plate 85 are flush, which also helps to achieve the consistency of the appearance of the base 81.

[0117] Next, the second ambulatory blood pressure monitor 200 of this application will be introduced. It is understood that the second ambulatory blood pressure monitor 200 is a fully functional, stand-alone ambulatory blood pressure monitor.

[0118] like Figure 1 and Figure 2 As shown, the second cuff assembly 7 also includes a second airbag 72 disposed within the second cuff 71, which can wrap around the user's upper arm along with the second cuff 71. The air pump of the main unit 5 is connected to the second airbag 72 via a second air tube 73, and the air pump is also used to inflate and deflate the second airbag 72. A pressure sensor is used to detect the pressure within the second air tube 73 and the second airbag 72. After the second airbag 72 is inflated, it can apply pressure to the user's upper arm. The pressure sensor can sense changes in pressure within the second airbag 72 and convert them into electrical signals.

[0119] The second sleeve 71 has a multi-layered fabric structure. The second airbag 72 is positioned between two adjacent layers of fabric.

[0120] Please see Figure 1 and Figure 2 As shown, in one embodiment, the carrying case 4 includes a bag body 41 and a strap 42. The bag body 41 has a receiving cavity 410 for accommodating at least a portion of the main unit 5. The strap 42 is connected to opposite sides of the bag body 41. The strap 42 is used by the user to hang the main unit 5 at a suitable position on their body.

[0121] Please see Figure 1 and Figure 2 As shown, in one embodiment, the bag body 41 is provided with a viewing window 411. The viewing window 411 allows the user to observe the display screen 56 of the host 5 from the outside of the bag body 41. In this way, the host 5 is housed inside the bag body 41, and the user can directly observe the relevant detection information without having to remove the host 5 from the bag body 41.

[0122] The viewing window 411 can be a perforated window communicating with the receiving cavity 410, or it can be a transparent layer. In one embodiment, at least one button 57 of the host 5 can correspond to the viewing window 411, or it can be set without corresponding to the viewing window 411. When the button 57 is blocked by the bag body 41, the user can perform blind operation through the bag body 41.

[0123] In one embodiment, the length of the strap 42 is adjustable. This is designed to accommodate the wearing needs of users of different heights and different wearing styles.

[0124] The portable bag 4 is made of flexible material.

[0125] In one embodiment, the second ambulatory blood pressure monitor 200 may also include a snap-fit ​​assembly 8 as described above, which is disposed between the second cuff 71 and the housing 51 of the main unit 5. This arrangement allows the user to temporarily secure the main unit 5 to the second cuff 71 when choosing to wear the second ambulatory blood pressure monitor 200 but not wanting to temporarily store the main unit 5 in the carrying case 4. The engagement method between the snap-fit ​​assembly 8 and the second cuff 71 is described in detail above with the engagement method with the first cuff 61, and will not be repeated here.

[0126] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
