The invention discloses a multi-section
venipuncture tourniquet device, and relates to the technical field of
medical instruments. Comprising two telescopic frames which are symmetrically arranged, a holding rod, a first supporting plate and a second supporting plate are sequentially and fixedly installed between the two telescopic frames, a
tourniquet is arranged above the holding rod, a plurality of automatic telescopic rods are installed at the bottom of the
tourniquet in a
dense array mode, tourniquet balls are arranged at the bottoms of the automatic telescopic rods, and pressure sensors, temperature sensors and heating wires are arranged in the tourniquet balls; a camera is arranged at the bottom of the tourniquet, a touch screen is arranged at the top of the tourniquet, and a controller is arranged in the tourniquet and electrically connected with the touch screen and the automatic telescopic rod. The touch screen presents the distribution condition of veins on the back of the hand of a patient, a finger selects one
vein on the touch screen and draws a corresponding track, the tourniquet stretches out the automatic telescopic rod according to the track, the tourniquet ball is pressed on the corresponding
vein, rolling pressing is conducted on the
vein in a targeted mode, meanwhile, the hot compress function is matched,
blood vessel dilatation is effectively promoted, and the
blood vessel dilatation rate is increased. And the veins are fully filled and exposed.
