[0021] The clamping mechanism 4 includes arc-shaped support one 41 and arc-shaped support two 42 clamped on both sides of the ultrasonic probe 6, the other side of the arc-shaped support one 41 is rotatably provided with a support shaft 43, the support shaft 43 is fixedly provided in the through-hole, the side of the arc plate 1 is provided with an internal threaded hole, a threaded rod 44 is arranged in the internal threaded hole, one end of the threaded rod 44 close to the arc-shaped support two 42 is not externally threaded, one end of the threaded rod 44 is rotatably connected with the other side of the arc-shaped support two 42, the other end of the threaded rod 44 is provided with an operating handle 441, there is a certain damping between the arc-shaped support one 41 and the support shaft 43 and between the arc-shaped support two 42 and the threaded rod 44, so that the angle adjustment of the arc-shaped support one 41 and the arc-shaped support two 42 to the ultrasonic probe 6 is more stable.
[0022] The other end of the restraint band 3 is provided with a support rod 31, a plurality of limiting grooves 21 are arranged on one of the support plates 2, and the support rod 31 is separably arranged in the limiting groove 21.
[0023] The inner side of the arc plate 1 is provided with a rubber pad 5, and the ultrasonic probe 6 passes through the rubber pad 5 and contacts the patient's arm.
[0024] The other end of the restraint band 3 is provided with a containing hole 32 allowing the fingers to pass through, and a containing groove 22 for accommodating the fingers is arranged on the plurality of limiting grooves 21.
[0025] One end of the restraint band 3 is provided with a rivet 33, one end of the restraint band 3 passes through the rubber pad 5 and is riveted with the arc plate 1 through the rivet 33.
[0026] The restraint band 3 is an elastic webbing.
[0027] The specific working process and principle of the utility model are as follows:
[0028] The patient's arm is inserted between the restraint belt 3 and the arc plate 1, the ultrasonic probe 6 is placed between the arc support one 41 and the arc support two 42, and then the handle 441 is rotated to move the screw rod 44 along the end of the arc plate 1 close to the ultrasonic probe 6. Since the screw rod 44 is rotationally connected with the arc support two 42, the arc support two 42 is close to the arc support one 41 under the limiting action of the ultrasonic probe 6, until the ultrasonic probe 6 is clamped by the arc support one 41 and the arc support two 42, stop rotating the handle, slide the arc plate 1 along the arm axis and swing the ultrasonic probe 6 to adjust the angle of the ultrasonic probe 6, until the ultrasonic probe 6 detects the position of the venous blood vessel, and then stop moving the ultrasonic probe 6.
[0029] The support rod 31 on the handheld restraint belt 3 is supported and tightened, so that the restraint belt 3 firmly fixes the arm between the arc plate 1 and the restraint belt 3, the ultrasonic probe 6 is in close contact with the skin, and then the support rod 31 is pressed into the limiting slot 21 on the support plate 2 to complete the fixation of the restraint belt 3. At this time, the ultrasonic probe 6 is fixed under the action of being pressed against the skin and the restraint and limitation of the arc support one 41 and the arc support two 42.

[0033] Through the cooperation of the restraint belt 3 and the arc plate 1, the arm is firmly and reliably fixed. Through the cooperation of the support rod 31 and the limiting slot 21, the fixation and release of the restraint belt 3 are more convenient and fast. Through the design of the accommodating groove 22 and the accommodating hole 32, the index finger and the thumb are facilitated to put the support rod 31 into the limiting slot 21 and take the support rod 31 out of the limiting slot 21. The restraint belt 3 and the arc plate 1 firmly and reliably fix the arm, and release conveniently and quickly.
[0034] Through the support of the support plate 2 to the arc plate 1, the whole support is prevented from being turned over due to the movement of the patient's arm, further improving the stability of the support, and thereby improving the stability of the PICC catheterization.
