Description

Technical Field

[0001] This application relates to the field of blood pressure measurement and massage technology, and in particular to a device capable of automatic bandaging. Background Technology

[0002] Current blood pressure measurement and limb massage devices require the operator or user to manually attach the cuff to the limb. Since manual attachment necessitates proper adjustment of the cuff's position and tightness, users with limited mobility or poor vision may struggle to achieve this. Incorrect attachment, resulting in a cuff that is too loose or too tight, can affect the accuracy of blood pressure measurements and the effectiveness of the massage. Therefore, manual attachment presents certain limitations when performing measurements or massages.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] This application provides an automatic bandaging device to address the problem that some users with limited mobility or poor vision cannot achieve proper bandaging. If the bandaging is not done correctly, the cuff may be too loose or too tight, which can affect the accuracy of blood pressure measurement and the effectiveness of massage.

[0005] In a first aspect, this application provides an automatic strapping device, including a main support, a strapping airbag structure, an air supply structure, a pressure detection structure, and a control on / off structure. The air supply structure, pressure detection structure, and control on / off structure are disposed on the outer side of the main support, which is cylindrical. The strapping airbag structure is disposed on the inner side of the main support. The air supply structure is connected to both the pressure detection structure and the control on / off structure. The control on / off structure is connected to the strapping airbag structure. The air supply structure supplies air to the strapping airbag structure through the control on / off structure. The pressure detection structure detects the gas pressure, and when the gas pressure reaches a preset first pressure value, it sends a disconnection signal to the control on / off structure, thereby disconnecting the connection between the control on / off structure and the air supply structure.

[0006] Optionally, the control on / off structure includes a dual-channel solenoid valve and a PCBA main board. The inlet end of the dual-channel solenoid valve is connected to the air supply structure, and the outlet end of the dual-channel solenoid valve is connected to the strapping airbag structure. The PCBA main board is electrically connected to the air supply structure, the pressure detection structure, and the dual-channel solenoid valve.

[0007] Optionally, it also includes a multi-channel hose, which is connected to the gas supply structure, the inlet end of the dual-channel solenoid valve, the pressure detection structure, and the proportional valve, respectively.

[0008] Optionally, the strapping airbag structure includes a stacked airbag and an inner ring support plate. The stacked airbag is disposed inside the main support frame, and the inner ring support plate is disposed inside the stacked airbag. The inner ring support plate is wound into a cylindrical shape and assembled inside the stacked airbag to compress the stacked airbag between the main support frame and the inner ring support plate. The stacked airbag is connected to the outlet section of a dual-channel solenoid valve. An inner airbag for compressing the limb is disposed inside the inner ring support plate, and the inner airbag is connected to a multi-channel hose.

[0009] Optionally, it also includes an internal component support, which is fixed to the outer periphery of the main support, and the gas supply structure, pressure detection structure, and control on / off structure are disposed inside the internal component support.

[0010] Optionally, the pressure detection structure is a pressure sensor.

[0011] Optionally, the stacked airbag includes: a large airbag as the main body of the stacked airbag, and a number of small airbags disposed on the large airbag. The large airbag is formed by folding and welding a single layer of airbag material, and an air nozzle for connecting with the air supply structure is provided in the middle of its fold line. The small airbags are formed by welding double layers of material, and an air passage for connecting with the air nozzle is left at the welding position of the small airbags.

[0012] Optionally, the inner airbag is formed by folding and welding a single layer of airbag material, and an air nozzle structure for connecting with the air supply structure is provided in the middle of its fold line.

[0013] Optionally, it also includes a battery disposed within an internal component support and electrically connected to the PCBA motherboard.

[0014] Optionally, the dual-way solenoid valve is a normally open solenoid valve. When the gas supply structure inflates the stacked airbag and the inner airbag to the point that the gas pressure reaches the first pressure value, the PCBA main board energizes the dual-way solenoid valve to disconnect the connection between the dual-way solenoid valve and the stacked airbag. When the gas pressure reaches the second pressure value, the PCBA main board shuts off the gas supply of the gas supply structure.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art:

[0016] This embodiment of the application sets up a strapping airbag structure, an air supply structure, a pressure detection structure, and a control on / off structure. The air supply structure supplies air to the strapping airbag structure through the control on / off structure. The pressure detection structure detects the gas pressure, and when the gas pressure reaches a preset first pressure value, it sends a disconnection signal to the control on / off structure. The control on / off structure disconnects the connection between its part and the air supply structure, thereby realizing automatic strapping of the user's limbs. For some people with limited mobility or poor vision, correct strapping can be achieved without manual strapping, which helps to ensure the accuracy of blood pressure measurement and the massage effect. It avoids inaccurate measurement results and poor massage effect due to incorrect strapping by the user, as well as limb injury due to excessively tight manual strapping. Attached Figure Description

[0029] 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.

[0030] 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.

[0031] 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.

[0032] To address the technical problems in the prior art, this application provides an automatic limb binding device. This device comprises a binding airbag structure, an air supply structure, a pressure detection structure, and a control on / off structure. The air supply structure supplies air to the binding airbag structure via the control on / off structure. The pressure detection structure detects the gas pressure, and when the gas pressure reaches a preset first pressure value, it sends a disconnect signal to the control on / off structure, thus disconnecting the connection between the control on / off structure and the air supply structure. This achieves automatic limb binding for users with mobility impairments or poor vision, eliminating the need for manual binding. This helps ensure the accuracy of blood pressure measurements and the effectiveness of massage, avoiding inaccurate measurements, poor massage effects, and limb injuries caused by improper binding or excessively tight binding.

[0033] Figure 1-3 This application provides an automatic ligation device for automatically binding limbs, facilitating subsequent blood pressure measurement and massage. The device includes a main support 1, a ligation airbag structure 2, an air supply structure 3, a pressure detection structure 4, and a control on / off structure 5. The air supply structure 3, pressure detection structure 4, and control on / off structure 5 are disposed on the outer side of the main support 1, which is cylindrical. The ligation airbag structure 2 surrounds the inner side of the main support 1. The air supply structure 3 is connected to both the pressure detection structure 4 and the control on / off structure 5, and the control on / off structure 5 is connected to the ligation airbag structure 2. The air supply structure 3 and pressure detection structure 4 are electrically connected to the control on / off structure 5. Preferably, the pressure detection structure 4 is a pressure sensor, and the air supply structure 3 is a miniature air pump.

[0034] During operation, the on / off control structure 5 controls the air supply structure 3 to supply air to the strapping airbag structure 2. The pressure detection structure 4 detects the gas pressure in real time. When the gas pressure reaches the preset first pressure value, it sends a disconnection signal to the on / off control structure 5. The on / off control structure 5 disconnects part of the connection with the air supply structure 3 according to the received disconnection signal.

[0035] Please see Figure 2 , Figure 3 The automatic strapping device also includes a multi-channel hose 6, and a control on / off structure 5 including a dual-way solenoid valve 7 and a PCBA main board 8. The multi-channel hose 6 is connected to the air supply structure 3, the inlet end of the dual-way solenoid valve 7, the pressure detection structure 4, and the proportional valve 14. Specifically, the inlet end of the dual-way solenoid valve 7 is connected to the air supply structure 3 via the multi-channel hose 6, and the outlet end is connected to the strapping airbag structure 2. The PCBA main board 8 is electrically connected to the air supply structure 3, the pressure detection structure 4, the dual-way solenoid valve 7, and the proportional valve. The multi-channel hose 6 enables the connection of the air supply structure 3, the control on / off structure 5, the pressure detection structure 4, and the proportional valve. The pressure detection structure 4 can obtain the gas pressure inside the strapping airbag structure 2 by detecting the pressure inside the connected multi-channel hose 6, avoiding the need for additional through holes that could lead to gas leakage.

[0036] Please see Figure 2 , Figure 3 The airbag structure 2 includes a stacked airbag 9 and an inner ring support plate 10. The stacked airbag 9 is disposed inside the main support 1. The inner ring support plate 10 is wound into a cylindrical shape and assembled inside the stacked airbag 9 to press the stacked airbag 9 between the main support 1 and the inner ring support plate 10. The stacked airbag 9 is connected to the outlet section of the dual-way solenoid valve 7. An inner airbag 11 for compressing the limb is disposed inside the inner ring support plate 10. The inner airbag 11 is connected to the multi-channel hose 6. Specifically, one end is wrapped with fabric and folded to contact the inner ring support plate 10 to reduce friction and friction noise during sliding. The inner ring support plate 10 is located between the stacked airbag 9 and the inner airbag 11. The stacked airbag 9 expands during inflation, first significantly restricting the space within the main support 1 so that the inner dimensions of the strapping airbag structure 2 are close to the user's limb dimensions. After the stacked airbag 9 completes its function, the inner airbag 11 is inflated to further restrict the inner dimensions of the strapping airbag structure 2, continuously applying pressure to the user's limb within a reasonable range, ultimately achieving pressure suitable for blood pressure measurement or massage. The inner ring support 10 provides a fixed position for the inner airbag 11 and prevents the stacked airbag 9 from contacting and compressing the inner airbag 11 during inflation, reducing the possibility of the inner airbag 11 being squeezed out or damaged. Please refer to [link to relevant documentation]. Figure 4-7The stacked airbag 9 includes: a large airbag 17 as the main body of the stacked airbag 9, and several small airbags 18 disposed on the large airbag 17. The large airbag 17 is formed by folding and welding a single layer of airbag material, and an air nozzle 15 for connecting with the air supply structure 3 is provided in the middle of its fold line. The small airbags 18 are formed by welding two layers of material, and an air passage for connecting with the air nozzle 15 is left at the weld position of the small airbag 18. The inner airbag 11 is formed by folding and welding a single layer of airbag material, and an air nozzle structure 16 for connecting with the air supply structure 3 is provided in the middle of its fold line.

[0037] Furthermore, the dual-channel solenoid valve 7 is a normally open type. When the gas supply structure 3 inflates the stacked airbag 9 and the inner airbag 11 until the gas pressure reaches the first pressure value, the PCBA main board 8 energizes the dual-channel solenoid valve 7 to disconnect the connection between the dual-channel solenoid valve 7 and the stacked airbag 9. When the gas pressure reaches the second pressure value, the PCBA main board 8 shuts off the gas supply state of the gas supply structure. Specifically, during the initial gas supply of the gas supply structure 3, gas is directly supplied to the inner airbag 11 through the multi-channel hose 6, and simultaneously supplied to the stacked airbag through the dual-channel solenoid valve 7 connected to the multi-channel hose 6. During the gas supply process, the stacked airbag 9 and the inner airbag 11 continuously expand, and the internal gas pressure continuously increases. When the gas pressure reaches the set first pressure value, the PCBA main board 8 sends a corresponding control signal to the dual-channel solenoid valve 7, energizing the dual-channel solenoid valve 7 to cut off the gas supply state of the stacked airbag 9, at which point the automatic binding work is completed. The air passage between the air supply structure 3 and the inner airbag 11 remains connected. Therefore, the air supply structure 3 continues to inflate the inner airbag 11 until the gas pressure reaches the preset second pressure value. At this point, the PCBA mainboard 8 controls the air supply structure 3 to shut off. Then, the proportional valve 14 begins to gradually depressurize the stacked airbags, and the blood pressure is detected by the blood pressure detection structure, collecting the user's blood pressure data. After the blood pressure measurement is completed, the PCBA mainboard 8 controls the proportional valve 14 and the dual-way solenoid valve 7 to de-energize and reset. At this time, the gas in the stacked airbag 9 and the inner airbag 11 is completely discharged through the proportional valve 14, thus completing the overall blood pressure measurement.

[0038] In this invention, the proportional valve 14, under the control of the PCBA main board 8, closes the air passage when energized and opens the air passage when de-energized to achieve exhaust. It is understood that the magnitudes of the first and second pressure values ​​are not limited and can be set according to the actual product structure.

[0039] Please continue reading. Figure 2 , Figure 3The automatic binding device also includes an internal component support 12, which is fixed to the outer periphery of the main support 1. The air supply structure 3, pressure detection structure 4, and on / off control structure 5 are disposed inside the internal component support 12. The internal component support 12 provides protective space to prevent internal components from being easily scratched or damaged.

[0040] Please continue reading. Figure 2 , Figure 3 The automatic binding device also includes a battery 13, which is housed within the internal component support 12 and electrically connected to the PCBA mainboard 8. The battery 13 allows the product to operate without a power cord, increasing ease of use and portability. Preferably, the battery 13 can be a dry cell battery or a rechargeable battery.
