At this time, the rotating driving member d2376 drives the rotating shaft 2373 to rotate, driving the gear n2377 to rotate. Since the gear n2377 is meshed with the rack 2371, the two ends of the flexible strip 235 are driven to slide in the groove 2321, thereby tightening the flexible strip 235 to tie the patient's arm, which is convenient for subsequent puncture of the blood vessels on the back of the patient's hand: Pushing process: fill the airbag b241 with gas, the airbag b241 expands, and drives the arc slider d2464 to slide into the arc slider c2463, the arc slider c2463 to slide into the arc slider b2462, and the arc slider b2462 to slide into the arc block a2461. Fig.12 As shown in the figure, the airbag b241 expands and squeezes the patient's arm in a circular manner along the X direction, squeezing the blood in the arm along the X direction, causing the blood vessels on the back of the palm to swell and become congested, making it easier for medical personnel to insert the infusion needle into the blood vessel for infusion; It should be noted that: the power for the arc slider d2464 to slide into the arc slider c2463, the arc slider c2463 to slide into the arc slider b2462, and the arc slider b2462 to slide into the arc block a2461 is pneumatically driven, that is, gas is injected into the arc block a2461 through a hose, so that the arc slider d2464, the arc slider c2463 and the arc slider b2462 extend outward, and the gas in the arc block a2461 is extracted to realize the arc slider d2464, the arc slider c2463 and the arc slider b2462 retract inward; it should be noted that: the hose is not drawn; Massage process: The telescopic part 246 has 6 groups, and the initial state is as follows Fig.13 As shown, the three groups of the drive intervals are in a contracted state (such as Fig.14 As shown), gas is filled into the airbag b241, and the airbag b241 expands and contacts the patient's wrist from the area of ​​the contracted telescopic part 246. At this time, the rotating drive member f244 drives the gear u245 to rotate, driving the rotating ring 242 to rotate. Since the airbag b241 is flexible and deformable, as the rotating ring 242 rotates, the airbag b241 moves the squeezing area of ​​the patient's arm, thereby massaging the patient's arm. It should be noted that the rotation of the rotating ring 242 is reciprocating, that is, it rotates 60° clockwise, and then rotates 60° clockwise. Because the rotating ring 242 is provided with a hose (the hose is used to inflate the arc block a2461), if the rotating ring 242 rotates in one direction all the time, the hose will be entangled, affecting subsequent use.
