[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Please see Figures 1-7One embodiment of the present invention provides a 360-degree adaptively adjustable dynamic blood pressure cuff, comprising a blood pressure cuff rotating structure 1, which includes a metal buckle 5 and a cuff 6. The rotating structure 1 also includes a restraint body 2, a rotating body 3, and an airbag 4. The airbag 4 is fixedly installed on the inner end of the cuff 6. The rotating body 3 and the restraint body 2 are rotatably and sealed together. The lower end of the restraint body 2 is fixedly connected to the airbag 4. The lower end of the metal buckle 5 is fixedly installed on the upper end of the cuff 6. The restraint body 2 includes a restraint piece 7, a fixing shaft 8, and a first fixing frame 9.

The air guide tube 14 is fixedly connected to the outer end of the sealing ring 12. The internal space of the sealing ring 12 is connected to the internal space of the air guide tube 14. The second sealing ring 15 is fixedly connected to the lower inner end of the sealing ring 12. The lower wall of the second sealing ring 15 slides and presses against the airbag 4. The second fixing frame 16... The first fixing bracket 9 is fixedly connected to the inner end of the sealing ring 12, and the inner end of the second fixing bracket 16 is rotatably mounted on the outer end of the fixing shaft 8. The airbag 4 includes an elastic baffle 18, a bag body 20, and an air nozzle 21. The lower end of the elastic baffle 18 is fixedly connected to the upper end of the bag body 20, and the air nozzle 21 is fixedly connected to the upper end of the elastic baffle 18. The upper wall of the air nozzle 21 slides and presses against the second sealing ring 15, and the upper wall of the air nozzle 21 slides and contacts the sealing ring 12. The first fixing bracket 9 is fixedly connected to the inner end of the air nozzle 21. During use, when the user needs to rotate the air inflator, the air guide tube 14 is manually operated to drive the sealing ring 12 to rotate. The sealing ring 12 then drives the second fixing bracket 16 to rotate along the outer end of the fixing shaft 8, thereby achieving flexible adjustment. The direction of the air guide tube 14 is adjusted to facilitate changing the inflation posture, making it easier for the user to inflate the air. When the user inflates the air, the gas enters the sealing ring 12 through the air guide tube 14, creating a high pressure inside the sealing ring 12. This pressure acts on the inside of the first sealing ring 11 and the second sealing ring 15, creating outward pressure on them. This outward pressure ensures that the first sealing ring 11 is firmly pressed against the outer wall of the restraint piece 7, and the second sealing ring 15 is firmly pressed against the upper wall of the air nozzle 21, thereby improving the sealing effect and preventing air leakage during inflation.

[0024] The restraint body 2 also includes a first ventilation hole 10, which is evenly hollowed out at the upper end of the first fixing frame 9; the first ventilation hole 10 connects the upper and lower spaces of the first fixing frame 9, allowing gas to pass through the first fixing frame 9.

The rotating sleeve 13 is fixedly connected to the second fixed frame 16 as a whole, and the rotating sleeve 13 is rotatably sleeved and installed on the outer wall of the fixed shaft 8. The second fixed frame 16 stabilizes the rotation angle between the second fixed frame 16 and the fixed shaft 8 by rotating the rotating sleeve 13 and the fixed shaft 8.

[0026] The rotating body 3 also includes a second vent 17, which is evenly hollowed out at the upper end of the second fixed frame 16; the second vent 17 connects the upper and lower spaces of the second fixed frame 16, allowing gas to freely pass through the second fixed frame 16.

[0027] The airbag 4 also includes an elastic connecting block 19. The upper end of the elastic connecting block 19 is fixedly connected to the lower end of the elastic baffle 18, and the lower end of the elastic connecting block 19 is fixedly connected to the upper end of the airbag body 20. The air nozzle 21 passes through the elastic baffle 18, the elastic connecting block 19 and the airbag body 20 and is fixedly connected together. The elastic baffle 18, the elastic connecting block 19, the airbag body 20 and the air nozzle 21 are an integral structure.

[0028] Please see Figures 5-6 An embodiment of the present invention provides: the metal buckle 5 includes a buckle ring 22, a bushing cap 23, a hardware limiting post 24, a hardware rotating shaft 25, a hardware base plate 26, and a bushing 27; the bushing 27 is welded to the middle interface end of the buckle ring 22, the hardware limiting post 24 is welded to the left positioning hole of the hardware base plate 26, the hardware rotating shaft 25 is welded to the right positioning hole of the hardware base plate 26, the lower inner ring of the bushing 27 is sleeved on the upper end of the hardware rotating shaft 25, the lower end of the bushing cap 23 is inserted into the inner hole of the bushing 27, the bushing cap 23 is tightened on the hardware rotating shaft 25, and the hardware base plate 26 is fixedly installed on the inner end of the sleeve 6.

[0029] Please see Figure 7 In one embodiment of the present invention, the cuff 6 includes a body 28, a hook and loop fastener 29, and a hook and loop fastener 31. The lower end of the hook and loop fastener 29 is fixedly connected to the upper end of one side of the body 28, and the hook and loop fastener 31 is fixedly connected to the upper end of the body 28. The body 28 is sleeved and fixedly installed between the elastic baffle 18 and the pouch 20. The elastic baffle 18 and the body 28 are sewn together. When the device needs to be worn on the hand, the end of the cuff 6 located on the hook and loop fastener 29 is passed through the buckle 22, and then the hook and loop fastener 29 is folded in half and attached to the hook and loop fastener 31 to achieve the purpose of binding the device on the arm. Finally, the angle of the rotating body 3 is adjusted until it is convenient for the user to inflate the device, and then the inflation work is performed.

[0030] The sleeve 6 also includes an elastic protrusion 30, which is fixedly installed inside the belt body 28; the elastic protrusion 30 makes it easy to pinch with your hand, thereby preventing slippage.

[0031] Working principle: During use, when the user needs to rotate the air pumping direction, the air guide tube 14 is manually operated to rotate the sealing ring 12. The sealing ring 12 then rotates the second fixed frame 16 along the outer end of the fixed shaft 8, thereby flexibly adjusting the direction of the air guide tube 14 to facilitate changing the pumping posture. This method of changing the pumping posture makes it easier for the user to pump air. After the user pumps air, the gas enters the sealing ring 12 through the air guide tube 14, creating high pressure inside the sealing ring 12. This pressure acts on the inside of the first sealing ring 11 and the second sealing ring 15, creating outward pressure. This outward pressure from the first sealing ring 11 firmly presses against the outer wall of the restraint piece 7, and simultaneously firmly presses the second sealing ring 15 against the upper wall of the air nozzle 21, thereby improving the sealing effect and preventing air leakage during pumping. The first vent 10 connects to the upper part of the first fixed frame 9. The space on the side and bottom allows gas to pass through the first fixed frame 9; the second fixed frame 16 is stabilized by rotating the rotating sleeve 13 and the fixed shaft 8; the space between the upper and lower parts of the second fixed frame 16 is connected by the second vent hole 17, allowing gas to pass freely through the second fixed frame 16; the position between the bushing 27 and the hardware rotating shaft 25 is fixed by the bushing cap 23, so that the buckle 22 is fixed on the right side of the hardware base plate 26, and can... The device can be rotated left and right; the metal base plate 26 is sewn together with the sleeve strap 6 by means of Velcro covering and stitching; when the device needs to be put on the hand, pass the end of the sleeve strap 6 on the Velcro surface 29 through the buckle 22, then fold the Velcro surface 29 in half and stick it to the Velcro hook surface 31 to achieve the purpose of binding the device on the arm. Finally, adjust the angle of the rotating body 3 until it is convenient for the user to inflate, and then perform the inflation work; the elastic protrusion 30 makes it easy to pinch and tighten by hand, thereby preventing slippage.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
