The movable set joint 200 includes an assembly seat 210 and a steering joint 220. The assembly seat 210 is located in the connecting section 101 of the cuff 100. The assembly seat 210 is attached to the airbag 140 and partially exposed to the outside of the cuff 100 through the curved assembly elastic piece 130 and the first cladding layer 110. In addition, the assembly base 210 is fixed to the curved assembly elastic piece 130 by fastening. In detail, the outer side of the assembly base 210 further has a buckle protrusion 212 and a stop protrusion 213. Assembly The seat assembly 210 is disposed with the curved assembly elastic piece 130, and the curved assembly elastic piece 130 is engaged between the buckle protrusion 212 and the stop protrusion 213 to engage the assembly seat 210 with the curved assembly elastic piece 130. The assembly 210 extends along a central axis A and is located outside of the cuff 100. The central axis A of the assembly base 210 is parallel to the radial direction of the cylindrical cuff 100 (in the direction indicated by the arrow D in FIG. 1).

The steering joint 220 includes a connected pivoting section 221 and a set of connecting sections 222. The pivoting section 221 is pivotable about an axis of rotation R (rotating in the direction indicated by the arrow a) to the assembly base 210, and the axis of rotation R is parallel to the central axis A of the assembly base 210. In the present embodiment, the rotation axis R is coaxial with the central axis A, but the invention is not limited thereto. In other embodiments, the rotation axis R and the central axis A may also be non-coaxial.

In addition, the steering joint 220 has an air flow passage 230. The air flow channel 230 extends from the pivoting section 221 to the assembly section 222. The airflow channel 230 is adjacent to one end of the pivoting section 221 and communicates with the airbag 140 of the cuff 100.

It should be noted here that the movable group connector 200 further includes a fixing pin 240. Moreover, the assembly base 210 and the pivoting section 221 each have a fixed slot 211, 221a. The two fixing slots 211 and 221a together form a space for the fixing pins 240 to be inserted, so that the fixing pins 240 can be detachably inserted into the two fixing slots 211 and 221a. When the fixing pin 240 is inserted into the two fixing slots 211, 221a, the fixing pin 240 allows the pivoting section 221 of the steering joint 220 to be rotatably assembled to the assembly base 210.

Since the air flow tube 300 is mounted on the cuff 100 through the movable set connector 200, the vulcanization device 10 is not wound by the left hand 22 or the right hand 24 of the measurer. The burden of winding the cuff device 10 is caused by the restriction.

In detail, as shown in FIG. 5, when the blood pressure measurement is performed by the cuff device of the sphygmomanometer of the present invention, the position of the movable group connector 200 is not limited to be located inside the left elbow of the measurer. In addition, the steering joint 220 of the movable group connector 200 is rotatable relative to the cuff 100, so that when the cuff 100 is to be wound around the left hand 22 of the measurer, the user can swing the airflow tube 300 toward the palm of the hand. The position (i.e., the position at which the general blood pressure measuring machine is placed) facilitates the measurement of the cuff 100 in the left hand 22 by itself.

In addition, if the measurer is left-handed and the pulse-pulsing device 10 is to be wound around the right hand 24, as shown in FIG. 6, the flow tube 300 can also be moved along the arrow b through the design of the movable assembly block 200. The direction indicated is rotated by 180 degrees with respect to the cuff 100. Here, it is not limited that the rotation is clockwise or counterclockwise, so that the measurer is still not subjected to the airflow tube 300 when the cuff 100 is wound in the right hand. The pendulum restriction causes a burden on the crimping device 10 to be wound.

According to the above-described embodiment, the movable group joint and the pulsator having the movable set joint can be rotated relative to the assembly seat through the steering joint of the movable joint, and the rotation axis of the steering joint is parallel to the central axis of the assembly. The air flow tube can be rotated relative to the pressure band to selectively swing to the opposite side of the cuff, thereby preventing the user from being restricted by the pendulum of the air tube. The burden of winding the cuff device. In this way, the convenience of winding the cuff tape around the left hand and the right hand can be achieved.
