Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0046] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0047] To address the technical problems of easy blockage of the air passage and easy loosening and breakage of the cable in the prior art, this application provides a tunnel-type blood pressure monitor, which can improve product reliability.

[0048] Firstly, Figures 1 to 6 A tunnel-type blood pressure monitor provided in this application includes a support 1, a control component 23, a retractable arm tube 2, and a data acquisition component 3. The support 1 includes multiple mounting seats, which are detachably connected end-to-end to form a cylindrical structure with a mounting cavity 12a. The control component 23 is located on the side of the support 1 away from the mounting cavity 12a. The retractable arm tube 2 includes a variable diameter ring 21 and a toothed belt 22. The variable diameter ring 21 is circumferentially disposed within the mounting cavity 12a and fits against the cavity wall of the mounting cavity 12a. The toothed belt 22 is located inside the mounting cavity 12a and fits against the cavity wall of the mounting cavity 12a. One end of the toothed belt 22 is connected to the control component 23, and the other end passes through the bracket 1 and is connected to the variable diameter ring 21. The acquisition component 3 is located on the side of the bracket 1 away from the mounting cavity 12a, and the other part is located inside the mounting cavity 12a. The acquisition component 3 has an airbag (not labeled in the figure) and a mesh 34. The airbag is located on the side of the variable diameter ring 21 facing the bracket 1. The edge of the mesh 34 is connected to both ends of the mounting cavity 12a and forms a sealing cavity 34a. The variable diameter ring 21 is located inside the sealing cavity 34a.

[0049] It should be noted that the airbag structure inside the tunnel boom is consistent with the airbag structure in the prior art.

[0050] Understandably, the toothed belt 22 not only allows the variable diameter ring 21 to establish a connection with the bracket 1, enabling the variable diameter ring 21 to be placed in the mounting cavity 12a, but also allows the size of the inner ring of the variable diameter ring 21 to be changed by moving the toothed belt 22. When the control component 23 starts working, the control component 23 controls the movement of the toothed belt 22, which enables the retractable boom 2 to automatically change size. The inner ring of the variable diameter ring 21 serves to place the arm during measurement. The mounting base serves to support and install the retractable boom 2. The size of the mounting cavity 12a formed by the interconnection of the mounting bases can be adjusted by adjusting the size of the mounting bases. Since the control component 23 and the acquisition component 3 are both mounted on the bracket 1, the problem of the cables and air pipes 33 on the boom needing to be connected to the base 5 in the prior art, which easily causes air blockage or cable loosening and breakage, is solved. This reduces the risk of air blockage and cable loosening and breakage, and improves the reliability of the product.

[0051] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, there are two or three assembly seats, which are connected to each other to form a cylindrical structure.

[0052] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the mounting bases are a first mounting base 110, a second mounting base 111, and a third mounting base 112. The cross-sections of the first mounting base 110, the second mounting base 111, and the third mounting base 112 are all arc-shaped. The two ends of the first mounting base 110, the two ends of the second mounting base 111, and the two ends of the third mounting base 112 are respectively provided with a first snap-fit ​​portion 113 and a second snap-fit ​​portion 114. The first mounting base 110, the second mounting base 111, and the third mounting base 112 are connected end to end through the first snap-fit ​​portion 113 and the second snap-fit ​​portion 114 to form a cylindrical structure.

[0053] It is understood that in some embodiments, the number of mounting bases can be two, while in this embodiment, the number of mounting bases is three, which can better divide the functions of each mounting base, and the three mounting bases make the bracket 1 less prone to deformation. The first snap-fit ​​part 113 and the second snap-fit ​​part 114 snap-fit ​​each other to allow the mounting bases to be quickly assembled and disassembled.

[0054] like Figure 2 and Figure 5 As shown, in the technical solution of this embodiment, the first snap-fit ​​part 113 has a flexible plug (not labeled in the figure), and the second snap-fit ​​part 114 has a mounting hole (not labeled in the figure), and the flexible plug matches the mounting hole.

[0055] Understandably, when the mounting base needs to be assembled into bracket 1, simply insert the elastic plug into the mounting hole; when bracket 1 needs to be disassembled, simply press the elastic plug while pulling the mounting base. It features stable connection and quick disassembly.

[0056] It should be noted that in some embodiments, the first snap-fit ​​portion 113 and the second snap-fit ​​portion 114 may also be configured as a mortise and tenon structure or a dovetail groove structure, or as a structure with a threaded hole and a bolt connection.

[0057] like Figures 2 to 6 As shown, in the technical solution of this embodiment, the bracket 1 is provided with a mounting part 13a, an abutment boss 14, a notch 15a, and a first limiting member 16; it is mounted on the side of the bracket 1 away from the mounting cavity 12a; the abutment boss 14 is provided on the side of the bracket 1 away from the mounting cavity 12a, and the toothed belt 22 passes through the abutment boss 14 at one end away from the variable diameter ring 21, and the height of the abutment boss 14 is the same as the thickness of the toothed belt 22; the notch 15a is provided on the bracket 1, and the toothed belt 22 extends into the mounting cavity 12a through the notch 15a and connects with the variable diameter ring 21; the first limiting member 16 is provided on one side of the notch 15a, and the height of the first limiting member 16 is flush with the top surface of the notch 15a.

[0058] Understandably, the mounting part 13a provides a mounting position for the control component 23 of the blood pressure monitor; the setting of the abutment boss 14 can limit the range of movement of the toothed belt 22, and when the toothed belt 22 is in contact with the abutment boss 14, the diameter of the variable diameter ring 21 reaches its maximum; the setting of the notch 15a facilitates the toothed belt 22 to connect better with the variable diameter ring 21, thereby allowing the toothed belt 22 to better change the diameter of the variable diameter ring 21; the setting of the first limiting member 16 can limit the position of the toothed belt 22, so that the toothed belt 22 will not detach from the bracket 1.

[0059] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, a limiting groove 12b is provided in the mounting cavity 12a. The limiting groove 12b is arranged circumferentially along the cavity wall of the mounting cavity 12a, and the toothed belt 22 is disposed in the limiting groove 12b.

[0060] Understandably, the limiting groove 12b is designed to prevent the toothed belt 22 from wobbling when it moves, thus ensuring that the toothed belt 22 can better change the diameter of the variable diameter ring 21.

[0061] like Figures 2 to 6As shown, in the technical solution of this embodiment, the variable diameter ring 21 includes: a ring body 21a, a limiting part 21b, and a fixing part 21c; the ring body 21a is disposed in the mounting cavity 12a; the limiting part 21b is disposed at one end of the ring body 21a; it has a second limiting member 21b1; the second limiting member 21b1 is disposed on the side of the limiting part 21b away from the mounting cavity 12a; the fixing part 21c is disposed at the other end of the ring body 21a; the fixing part 21c is disposed circumferentially along the mounting cavity 12a, passes through the second limiting member 21b1, and is connected to the toothed belt 22; the limiting part 21b and the fixing part 21c form a placement cavity 21d for placing an arm.

[0062] It is understood that the overall shape of the circumference body 21a is strip-shaped with two ends. The limiting part 21b and the fixing part 21c are respectively located at the two ends of the circumference body 21a. By setting a second limiting member 21b1 on the limiting part 21b, the circumference body 21a is always kept in a closed state within the mounting cavity 12a, ensuring that the circumference body 21a can be retracted to the size of an arm by the toothed belt 22 so that the blood pressure monitor can collect data such as blood pressure.

[0063] like Figures 2 to 6 As shown, in the technical solution of this embodiment, the toothed belt 22 includes: a toothed belt body 22a, a connecting portion 22b, an abutting portion 22c, and a transmission portion 22d; a portion of the toothed belt body 22a is located on the side of the bracket 1 away from the mounting cavity 12a, and the other portion is located in the limiting groove 12b; the connecting portion 22b is located at one end of the toothed belt body 22a located in the mounting cavity 12a; the connecting portion 22b extends into the mounting cavity 12a through a notch 15a and is connected to the fixing portion 21c; the abutting portion 22c is located at one end of the toothed belt body 22a away from the connecting portion 22b and passes through the abutting boss 14; the transmission portion 22d is located on the side of the toothed belt 22 away from the mounting cavity 12a; the transmission portion 22d passes through the first limiting member 16.

[0064] It is understandable that the toothed belt body 22a is strip-shaped with two ends. Different parts of the toothed belt body 22a have different functions. The connecting part 22b and the abutting part 22c are respectively located at both ends of the toothed belt body 22a. The transmission part 22d is located between the connecting part 22b and the abutting part 22c. The function of the connecting part 22b is to connect with the variable diameter ring 21 so that the variable diameter ring 21 moves with the toothed belt body 22a. The function of the abutting part 22c is to cooperate with the abutting boss 14 to limit the range of movement of the toothed belt body 22a, thereby limiting the maximum diameter of the variable diameter ring 21. The transmission part 22d is used to drive the drive assembly 24 so that the toothed belt body 22a moves automatically.

[0065] like Figures 2 to 6As shown, in the technical solution of this embodiment, the retractable boom 2 also includes a drive assembly 24 and a current sensor 25; the drive assembly 24 is located on the side of the bracket 1 away from the mounting cavity 12a; the drive assembly 24 has an input end and an output end, the input end is electrically connected to the control assembly 23; the output end is connected to the transmission part 22d; the current sensor 25 is located on the side of the bracket 1 away from the mounting cavity 12a; the current sensor 25 is electrically connected to the control assembly 23.

[0066] It is understood that the control component 23 has a control panel, a display screen, and control buttons, similar to the structure of a blood pressure monitor in the prior art. Pressing the control button enables the blood pressure monitor to automatically measure blood pressure. In this embodiment, the drive component 24 consists of a motor and a gear mounted on the moving end of the motor. The transmission part 22d in this embodiment consists of multiple sets of wave-shaped racks. The current sensor 25 works in conjunction with the motor. When the control button is pressed, the system performs a self-test. If the variable diameter ring 21 is loosened to its maximum position, the motor will stall, causing a large current (the set value is when the current is ≥2.5A and lasts for 1 second; this value is not yet certain and needs to be determined after final testing), and the motor will stop working. If it is not loosened to its maximum position, the motor reverses and drives the rack to loosen the variable diameter ring 21. When it is loosened to its maximum position... In the current state, the buckle at the end of the rack will get caught on the arm support 1, causing a stall. When the system detects a large current generated by the stalled motor, it stops rotating. After the arm is placed in the placement cavity 21d, the motor rotates forward, causing the rack to tighten the variable diameter ring 21. When the variable diameter ring 21 tightens and contacts the arm, a stall current of ≥2.5A is generated and lasts for one second. Then, the motor reverses for 200 milliseconds to loosen the variable diameter ring 21 slightly to prevent it from being too tight and affecting the user's comfort. At the same time, the self-locking characteristic of the worm gear in the reduction motor is used to lock and drive the gear to rotate. The gear meshes with the rack in the transmission part 22d, so that the force of the motor is transmitted to the toothed belt 22. When the motor rotates forward, the toothed belt 22 drives the variable diameter ring 21 to tighten. When the motor reverses, the diameter of the variable diameter ring 21 increases. The function of the acquisition component 3 is to collect the blood pressure of the person being measured.

[0067] like Figures 2 to 6 As shown, in the technical solution of this embodiment, the acquisition component 3 further includes: an air pump 32 and an air tube 33; the air pump 32 is located on the side of the bracket 1 away from the sealed cavity a; the air pump 32 is electrically connected to the control component 23; the air tube 33 is located on the side of the bracket 1 away from the sealed cavity a; one end of the air tube 33 is connected to the air pump 32, and the other end is connected to the airbag.

[0068] Understandably, when blood pressure needs to be measured, the control component 23 controls the air pump 32 to start working to inflate and pressurize the airbag. When the airbag is pressurized to the point of blocking the brachial artery, the pressurization stops (the airbag can be regarded as a signal collecting amplifier; when blood flows through the artery, it will generate airflow fluctuations. When the airbag compresses the artery, the signal is relatively weak, so the air pump 32 stops pressurizing). The proportional deflation valve starts to deflate at a constant speed. After the measurement is completed, the motor starts to reverse and release the variable diameter coil 21. It stops when a large current is detected, and the measurement ends.

[0069] like Figure 1 As shown, in the technical solution of this embodiment, the bracket 1 further includes:

[0070] The outer shell 4 has a cavity 41a; the mounting base is disposed in the cavity 41a;

[0071] The base 5 has an arm support 51; the outer shell 4 is pivotally connected to the base 5; the arm support 51 is provided with a switch 510 electrically connected to the control component 23, and the cross-section of the arm support 51 is arc-shaped.

[0072] Understandably, the outer casing 4 provides dust and pressure protection, effectively protecting the control component 23, the retractable arm 2, and the data acquisition component 3 mounted on the mounting base. The base 5 facilitates storage when the blood pressure monitor is not in use. It should be noted that when the blood pressure monitor is needed, since the outer casing 4 is pivotally connected to the base 5, the outer casing 4 can rotate relative to the base 5. After the outer casing 4 rotates, the control component 23, the retractable arm 2, and the data acquisition component 3 rotate together. At this time, the person being tested only needs to pass their arm through the placement cavity 21d and press the switch 510 with their elbow. The control component 23 receives the instruction and controls the drive component 24 to work. The drive component 24 causes the toothed belt 22 to move, causing the variable diameter coil 21 to begin to contract. After the variable diameter coil 21 contracts, the supporting air bladder contracts. During the contraction of the variable diameter coil 21, the control component 23 also simultaneously inflates the air bladder with the air pump 32, thereby enabling the blood pressure monitor to measure the blood pressure data of the person being tested.
