In order to limit the position of the U-shaped plate 9, the U-shaped plate 9 is provided with a plurality of slots 11 with openings distributed forward and along the vertical direction, the arc-shaped plate 1 is connected with two inverted L-shaped rods 12 in a sliding manner, and the front ends of the inverted L-shaped rods 12 can be inserted into the slots 11 on the corresponding sides.

In order to facilitate the movement of the inverted L-shaped rod 12, the stepped surface of the inverted L-shaped rod 12 is fixedly connected with the arc-shaped plate 1 through a tension spring, and the front end surface of the inverted L-shaped rod 12 is an inclined surface which is low in front and high in back.

In order to facilitate the free end of the fixing band to be bonded with the rear side of the fixing band, the upper surface of the rear side of the fixing band is provided with a female magic tape 13, and the free end of the fixing band is provided with a male magic tape 14 which can be bonded with the female magic tape 13.

In order to achieve better use effect, the U-shaped plate 9 is provided with an arc-shaped pressing groove 15 which is communicated from left to right and has a downward opening.

When the puncture needle is used, the reverse L-shaped rod 12 is inserted into the slot 11 at the lowest side, the U-shaped frame 2 is clamped into the clamping groove 8, the hook and loop fastener 14 and the hook and loop fastener 13 are in an initial state of adhesion, a patient puts an arm at the puncture side on the arc-shaped plate 1 and puts a hand at the left side of the arc-shaped plate 1, at the moment, the U-shaped plate 9 at the right side is pressed downwards, the U-shaped plate 9 at the right side drives the elastic clamping block 10 on the U-shaped plate to move downwards, after the U-shaped plate 9 at the right side is in contact with the inclined surface of the reverse L-shaped rod 12, the U-shaped plate 9 at the right side pushes the reverse L-shaped rod 12 to move backwards, and the tension spring at the right side is stretched;

when the inverted L-shaped rod 12 on the right side is separated from the corresponding slot 11, the inverted L-shaped plate moves downwards along with the continuation of the U-shaped plate 9, when the inverted L-shaped plate is separated from the U-shaped plate 9, the inverted L-shaped plate is inserted into the corresponding slot 11 under the action of tension of the tension spring, at the moment, the U-shaped plate 9 on the right side continues to be pressed downwards, the inverted L-shaped rod 12 makes back-and-forth reciprocating gap motion, when the arc-shaped pressing groove 15 on the right side is attached to the arm of a patient, the inverted L-shaped rod 12 on the right side is inserted into the corresponding slot 11 under the action of the tension spring, and the preliminary fixation of the arm of the patient is completed;

after the preliminary fixing of the arm of the patient is completed, similarly, the left U-shaped plate 9 is pressed to enable the left arc-shaped pressing groove 15 to be in contact with the arm of the patient, at the moment, the arm of the patient is fixed, and the patient can be punctured after the arm of the patient is fixed;

after puncture, one hand presses the puncture needle, the other hand pulls the pressing block 3 rightwards, the pressing block 3 drives the fixing band to move rightwards, the pressing block 3 is separated from the U-shaped frame 2 in the moving process of the pressing block 3, when the pressing block 3 moves to the position above the puncture part, the pressing block 3 is pressed downwards, when the needle groove 4 is contacted with the puncture needle, and the tube groove 5 is contacted with the dialysis tube, the hydrogel pad 6 is contacted with the arm of a patient, so that preliminary fixing of the pressing block 3 is completed;

after the pressing block 3 is preliminarily fixed, one hand presses the pressing block 3, the other hand pulls the free end of the fixing band upwards, when the hook and loop fastener 14 is separated from the hook and loop fastener 13, the free end of the fixing band continues to be pulled upwards, when the fixing band is tightened, the fixing band is pulled and kept in a tightened state, so that the hook and loop fastener 14 is bonded on the hook and loop fastener 13, at the moment, the pressing block 3 is fixed, and the puncture needle is preliminarily fixed;

after the puncture needle is preliminarily fixed, the dialysis tube is pulled to be clamped into the elastic fixture block 10 on the left side, the dialysis tube between the pressing block 3 and the elastic fixture block 10 on the left side is straightened, at the moment, the dialysis tube is pulled to be clamped into the elastic fixture block 10 on the right side, the length of a pipeline between the two elastic fixture blocks 10 is larger than the sum of the distance between the two elastic fixture blocks and two times of the length of the elastic fixture block 10, and at the moment, the puncture needle is fixed;

after the dialysis tube is fixed, if the arm of the patient moves, the arm of the patient drives the arc-shaped plate 1 and the puncture needle to synchronously move, the arc-shaped plate 1 drives the dialysis tube to synchronously move through the U-shaped plate 9 and the elastic clamping blocks 10, therefore, the puncture needle and the dialysis tube synchronously move at the moment, the phenomenon that the blood vessel is punctured by the displacement of the needle head and the dialysis tube falls off is avoided, if a passerby touches the dialysis tube, the dialysis tube drives the elastic clamping blocks 10 on the right side to rotate, and because the length of the pipeline between the two elastic clamping blocks 10 is greater than the sum of the distance between the two elastic clamping blocks and two times of the length of the elastic clamping blocks 10, the pipeline between the two elastic clamping blocks 10 on the right side is driven to be straightened when the elastic clamping blocks 10 on the right side rotate, and the possibility that the blood vessel is punctured by the displacement of the needle head and the dialysis tube is separated is reduced;

when the puncture needle is not required to be fixed, the pressing block 3 is pressed by one hand, the fixing band is pulled upwards by the other hand, when the hook-and-loop fastener 14 is separated from the hook-and-loop fastener 13, the fixing band is loosened and the pressing block 3 is pulled upwards, when the pressing block 3 and the hydrogel pad 6 are separated from the arm of the patient, the pressing block 3 is pulled leftwards to clamp the pressing block 3 on the U-shaped frame 2, at the moment, the puncture needle is moved out of the arm of the patient, the elastic clamping block 10 is pulled out of the dialysis tube, the inverted L-shaped rod 12 on the right side is pulled backwards after the dialysis tube is pulled out, the tension spring is stretched, when the inverted L-shaped rod 12 is separated from the slot 11, the U-shaped plate 9 on the right side is pulled upwards until the U-shaped plate 9 on the right side is recovered to the initial position, at the moment, the inverted L-shaped rod 12 on the right side is released, the inverted L-shaped rod 12 on the right side is inserted into the corresponding slot 11 under the tension force of the tension spring, and similarly, the left inverted L-shaped rod 12 on the left side is pulled backwards and the left U-shaped plate 9 is moved upwards, the left U-shaped plate 9 is restored to the initial position, and at this time, the patient can withdraw his arm.

The utility model has simple structure, convenient operation, novel conception and strong practicability, is provided with two U-shaped plates capable of moving up and down, two elastic clamping blocks and a pressing block capable of moving up and down, avoids the phenomenon that the needle head shifts to puncture the blood vessel caused by the movement of the arm of a patient, reduces the possibility that a passerby touches the dialysis tube to cause the dialysis tube to fall off, increases the comfort level of the patient and reduces the working difficulty of medical personnel.
