DETAILED DESCRIPTION

[0030] See also Figure 1-2 In an embodiment of the present invention, a wearable blood pressure detection device includes a sphygmomanometer body 1, a bandage 2 is fixedly connected to one side of the sphygmomanometer body 1, an inflatable plugging member 3 is assembled and connected to the other side of the sphygmomanometer body 1, the free end of the bandage 2 (the end away from the end connected to the sphygmomanometer body 1) passes through the inflatable plugging member 3, a clamping member 4 is movably provided on the bandage 2, and the free end of the bandage 2 is limited and clamped by the clamping member 4. The sphygmomanometer body 1 is a touch-screen blood pressure detection device commonly used in the prior art, an airbag 21 is embedded in the middle of the side of the bandage 2, and the airbag 21 is extended along the direction of the bandage 2, the inflatable plugging member 3 includes a shell 31 and a clamping assembly arranged in the shell 31 for clamping and limiting the bandage 2, a micro air pump for inflating the airbag 21 can be integrated in the sphygmomanometer body 1, and the airbag 21 can also be inflated by an external air pump, when worn, the bandage 2 is wrapped around the arm, the back side of the sphygmomanometer body 1 is attached to the skin surface, and the free end of the bandage 2 is clamped by the clamping member 4. After the free end passes around the arm, it passes through the inflatable sealing piece 3, and the free end is clamped and limited by the clamping piece 4. After the airbag 21 is inflated, the inflated bulging part of the airbag 21 is limited between the clamping assembly on the inflatable sealing piece 3 and the connection between the strap 2 and the sphygmomanometer body 1. In this way, it can be adjusted according to different users, and the inflation position can always be kept matching the adjusted size, so that different users can use the airbag 21 to fully wrap their arms during use, thereby ensuring the accuracy of the detection and the comfort of the detection personnel.

[0031] Among them, the surface of the strap 2 is provided with sanded hair 22 on both sides of the airbag 21. The sanded hair 22 can not only improve the comfort when wearing, but also cooperate with the bristles set on the free end of the strap 2 to form a simple pasting fixation, which is very convenient to use and the position of the strap 2 is not easy to shift. For convenience, the airbag 21 is only set on the surface of the strap 2 opposite to the rear side of the sphygmomanometer body 1, so that only the arm of the tester needs to be wrapped, and the sanded hair 22 can be set on both sides of the strap 2, which is not only convenient to wear, but also can improve comfort.

[0032] Furthermore, one side of the shell 31 is open, and a fixing rod 32 and a clamping rod 33 are arranged in parallel in the airbag 21. The fixing rod 32 is fixedly connected to the upper and lower inner walls of the shell 31, and sliding rods 34 are symmetrically fixedly connected on both sides of the shell 31. The sliding rod 34 passes through the fixing rod 32 and the clamping rod 33, and the clamping rod 33 is slidably connected with the sliding rod 34. When the clamping rod 33 slides on the sliding rod 34, it moves closer to or away from the fixing rod 32. A threaded sleeve 35 is arranged on the outer wall of the shell 31 through a threaded cooperation. The threaded sleeve 35 and the sliding rod 34 are arranged relatively to each other, and the threaded sleeve 35 is arranged to be fixed to the upper and lower inner walls of the shell 31. The threaded sleeve 35 is slidably sleeved on the outer periphery of the sliding rod 34. Preferably, the threaded sleeve 35 may be a tubular structure with a threaded outer wall. The threaded sleeve 35 may be rotated to push the clamping rod 33 closer to the fixing rod 32, and the clamping effect may be achieved by the clamping rod 33 and the fixing rod 32. When the free end of the binding strap 2 extends into the housing 31, it may bypass the fixing rod 32 and pass through the housing 31 from the inside to the outside between the fixing rod 32 and the clamping rod 33. In this way, after the clamping rod 33 and the fixing rod 32 are relatively close and clamped, the airflow of the airbag 21 may be closed by clamping. After the airbag 21 is inflated, it will not affect the wearing, and the use is more convenient.

[0033] In order to improve the limiting effect on the end of the strap 2, Figure 1 and Figure 3As shown, preferably, the clamping member 4 includes a sliding sleeve 41 that is slidably fitted on the outside of the strap 2 and a rotating cover 42 that is rotatably connected to the sliding sleeve 41 on the side away from the strap 2. The sliding sleeve 41 is a "C"-shaped structure, and the two ends of the sliding sleeve 41 are bent and fitted on the inner side of the strap 2 (the inner side of the strap 2 is the side close to the arm of the test person after wearing, and the outer side of the strap 2 is the side away from the arm of the test person after wearing, and the free end of the strap 2 passes through the inflatable seal After the blocking piece 3 is inserted, it will be turned over and attached to the outer side of the first layer of strap 2, so the original inner side will become the outer side), and after the free end of the strap 2 passes through the inflatable blocking piece 3 and passes through the rotating cover shell 42, a strip mounting seat 43 is fixedly connected to the side of the rotating cover shell 42 opposite to the sliding sleeve 41, and a limiting clamping member 5 is rotatably provided on the strip mounting seat 43. The limiting clamping member 5 can form a tight fitting effect on the free end of the strap 2 passing through the rotating cover shell 42.

[0034] Among them, the rotating cover shell 42 is elastically connected to one side away from the rotating connection with the sliding sleeve 41 with an elastic block 44, and the elastic block 44 is an "L"-shaped card plate. One side of the elastic block 44 is elastically connected to the rotating cover shell 42 through a spring sliding, and the other side of the elastic block 44 is slidingly engaged with the sliding sleeve 41. The elastic block 44 can limit the rotation of the rotating cover shell 42 relative to the sliding sleeve 41.

[0035] like Figure 3-Figure 11As shown, the limiting pressing member 5 includes a rotating shaft 51 symmetrically connected to the end of the strip mounting seat 43, a torsion spring is connected between the rotating shaft 51 and the strip mounting seat 43, and two connecting rods 52 are sleeved on the periphery of the two rotating shafts 51 away from the strip mounting seat 43, one of the connecting rods 52 is connected to the rotating shaft 51 for rotation, and the other connecting rod 52 is fixedly connected to the rotating shaft 51, and the connecting rod 52 fixedly connected to one rotating shaft 51 and the connecting rod 52 connected to the other rotating shaft 51 for rotation are set as a The torsion spring acts to make the ends of the two pressing parts that are relatively far away from each other tend to be relatively close to each other, and a column joint 53 is fixedly connected to the side of the connecting rod 52 fixedly connected to the rotating shaft 51 in the group of pressing parts, and a core shaft 56 is fixedly connected between the column joint 53 and the connecting rod 52 rotatably connected in the group of pressing parts. The outer periphery of the core shaft 56 is rotatably connected to an anti-slip sleeve 54, and the outer periphery of the column joint 53 is slidably matched to be connected to a ratchet ring 55 for limiting the unidirectional rotation of the anti-slip sleeve 54. The strip mounting seat 4 3, two traction ropes 6 are fixedly connected, and the two traction ropes 6 correspond to the two sets of clamping members respectively. The traction ropes 6 are connected to the ratchet ring 55 after movably passing through the rotating shaft 51, the connecting rod 52 and the column joint 53. The traction ropes 6 are wound around the outer periphery of the end of the rotating shaft 51. When the rotating shaft 51 rotates relative to the strip-shaped mounting seat 43 (the anti-slip sleeve 54 is pressed on the surface of the binding belt 2 and pressed hard), the two sets of clamping members are relatively opened. At this time, after the traction rope 6 wound around the outer periphery of the end of the rotating shaft 51 is loosened, the ratchet ring 55 slides from the outer periphery of the column joint 53. The two anti-slip sleeves 54 are moved to a state of one-way rotation limit cooperation with the anti-slip sleeves 54. At this time, the two sets of anti-slip sleeves 54 can cooperate with the tightening straps 2, and the two ratchet rings 55 can limit the corresponding anti-slip sleeves 54 from rotating in the opposite direction, so that the state of tightening the straps 2 can be maintained continuously. After the rotating cover 42 is relatively rotated to open, the pressure at the elastic block 44 is gradually removed, and the connecting rod 52 and the rotating shaft 51 rotate relatively, and the traction rope 6 is wound around the end of the rotating shaft 51, so that the traction ratchet ring 55 is pulled out of the limit cooperation with the anti-slip sleeves 54.

[0036] The end of the anti-slip sleeve 54 opposite to the column joint 53 is embedded with a groove, and a clamping plate 5401 is rotatably connected in the groove through a torsion spring, and the clamping plate 5401 is correspondingly and movably clamped and adapted with the ratchet ring 55. The inner wall of the ratchet ring 55 is fixedly connected with a core plate 5502 through multiple sets of brackets 5501, and the core plate 5502 is concentrically arranged with the ratchet ring 55. The outer wall of the column joint 53 is embedded with a slide groove 5301 along the axial direction, and the ratchet ring 55 is slidably fitted on the periphery of the column joint 53, and the bracket 5501 passes through the slide groove 5301 and is slidably adapted. The end of the traction rope 6 is fixedly connected to the core plate 5502, and a spring for pushing the ratchet ring 55 to approach the anti-slip sleeve 54 is connected between the core plate 5502 and the column joint 53. When the traction rope 6 is released from the end of the rotating shaft 51, the spring pushes the ratchet ring 55 to approach the anti-slip sleeve 54, and the ratchet ring 55 and the clamping plate 5401 form a one-way rotation limit fit (ratchet fit), and after the traction rope 6 is rewound around the end of the rotating shaft 51, the ratchet ring 55 can be pulled away from the anti-slip sleeve 54, and the spring is in a compressed state at this time. Such a matching mode can conveniently complete the switching between the one-way rotation limit and the free rotation, so that it can conveniently ensure that when the strap 2 is compressed, the anti-slip sleeve 54 can be in a one-way rotation state, avoiding the strap 2 from falling off and loosening, and the placement of the strap 2 is more flat. After the rotating cover 42 rotates relatively, the anti-slip sleeve 54 loses its force, and the rotating shaft 51 rotates to loosen the traction rope 6, so that the ratchet ring 55 can recover the fit between the detachment and the clamping plate 5401, which is convenient for the next use.

[0037] Furthermore, a threading hole 5101 for the traction rope 6 to pass through is embedded in the center of the rotating shaft 51 along the axial direction, and a guide groove 5102 is embedded on one side of the opening of the threading hole 5101 located at the end of the rotating shaft 51, and the guide groove 5102 extends to the side of the rotating shaft 51, and an annular groove 5103 is embedded in the outer periphery of the rotating shaft 51, and the annular groove 5103 is connected with the guide groove 5102. After the traction rope 6 extends from the strip mounting seat 43 to the annular groove 5103 and is wound, it extends from the guide groove 5102 into the threading hole 5101. In this way, when the rotating shaft 51 rotates, the guide groove 5102 and the annular groove 5103 can be used to complete the winding and unwinding of the traction rope 6. Through this winding method, it is convenient to overcome the action of the spring between the core plate 5502 and the column joint 53, and the traction is stable.
