[0012] A method for using a venous therapy anti-dislocation fixation device is also provided, which is used to operate a venous therapy anti-dislocation fixation device, comprising the following steps:

[0013] S1: After the infusion needle is inserted into the infusion bottle, the fixing ring and the groove are put on the outside of the infusion bottle and the infusion needle to restrict the infusion bottle and the infusion needle;

[0014] S2: When replacing the infusion bottle, first pinch the two sets of anti-slip strips and rotate the fixed ring to flip down. After flipping down the fixed ring, you can directly pull the infusion needle out of the infusion bottle;

[0015] S3: When changing the infusion needle, the rotating movable frame will squeeze the semicircular balls on both sides, and pushing the two sets of clamps will squeeze the infusion tube on the lower side of the infusion needle to block the entry of outside air.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the infusion needle is inserted into the infusion bottle, the fixed ring and the groove are put on the outside of the infusion bottle and the infusion needle. After the two sets of clamping blocks contact the bottleneck of the infusion bottle, they shrink and move toward the two sets of movable grooves, and at the same time squeeze the two sets of springs until the bottleneck of the infusion bottle moves to the inside of the bottleneck sleeve. The two sets of clamping blocks are respectively clamped on the outside of the bottleneck of the infusion bottle and clamped on the upper side of the bottleneck ring. Then the groove is put to the outside of the disc support. After the two sets of arc-shaped spring pieces are stretched open by the disc support and enter the groove, the deformed two sets of arc-shaped spring pieces rebound to limit the outside of the disc support, thereby completing the restriction of the infusion bottle and the infusion needle, preventing the infusion needle from being separated from the infusion bottle when the infusion tube is pulled, affecting the patient's treatment.

[0018] 2. When replacing the infusion bottle, you can first pinch the two sets of anti-slip strips to make the two sets of positioning springs close together and deform. The limiting card strip 1 on the positioning spring is separated from the limiting card strip 2 on the support sleeve, and then the fixing ring, the two sets of support sleeves, and the support rod can be rotated along the fixing nails respectively. The two sets of resistance shafts generate rotational damping for the rotating two sets of support rods to prevent the turned-down fixing ring from moving around at will. After turning down the fixing ring, the infusion needle can be directly pulled out from the infusion bottle, and then inserted into another infusion bottle. Pinch the two sets of pressing blocks to rotate the fixing ring and then clamp it at the bottleneck of the infusion bottle to complete the positioning purpose. Release the pressing blocks, and the limiting card strip 1 will engage with the limiting card strip 2 again to limit the horizontal support rod and the support sleeve, prevent the support sleeve from rotating and being pulled downward, and achieve the anti-slip effect.

[0019] 3. Each time the infusion needle is inserted into the infusion bottle at a different depth, the horizontal support rod can be directly pushed upward. With the elastic characteristics of the two sets of positioning springs, the horizontal support rod and the two sets of positioning springs move upward, quickly completing the distance between the horizontal support rod and the fixed ring, which is suitable for the different depths of the infusion needle inserted into the infusion bottle.

[0020] 4. Every time the infusion needle is changed, the two groups of supporting rods rotate down and drive the two groups of arc bars and the movable frame to rotate forward respectively, and the inclined position of the side of the movable frame squeezes the semicircular balls on both sides respectively. The two groups of movable rods drive the two groups of clamps to slide together and squeeze the two groups of springs. The two groups of clamps that move together will squeeze the infusion tube on the lower side of the infusion needle, thereby isolating the outside air when the infusion needle is pulled out, reducing the flow of air into the infusion tube, and preventing discomfort to the patient.

[0045] Working principle: After the infusion needle 3 is inserted into the infusion bottle 1, the fixed ring 514 and the groove 520 are put on the outside of the infusion bottle 1 and the infusion needle 3. After the two groups of clamping blocks 517 come into contact with the bottleneck of the infusion bottle 1, they shrink and move toward the two groups of movable grooves 516, while squeezing the two groups of springs 1 518 until the bottleneck of the infusion bottle 1 moves to the inside of the bottleneck sleeve 515. The two groups of clamping blocks 517 are respectively clamped on the outside of the bottleneck of the infusion bottle 1 and on the upper side of the bottleneck ring 2. Then the groove 520 is put on the outside of the disc holder 4.

After the fixing ring 514 is turned down, The infusion needle 3 can be directly pulled out from the infusion bottle 1 and then inserted into another infusion bottle 1 by pinching the two sets of pressing blocks 54 and rotating the fixing ring 514 to clamp the bottleneck of the infusion bottle 1 to complete the positioning purpose. The pressing block 54 is released, and the limiting card strip 1 53 is engaged with the limiting card strip 2 512 again to limit the horizontal support rod 51 and the support sleeve 511, preventing the support sleeve 511 from rotating and being pulled downward to achieve the anti-falling effect. The depth of each insertion of the infusion needle 3 into the infusion bottle 1 is different, and the horizontal support rod 51 can be directly pushed upward. With the elastic characteristics of the two sets of positioning spring pieces 52, the horizontal support rod 51 and the two sets of positioning spring pieces 52 move upward quickly. The distance between the horizontal support rod 51 and the fixed ring 514 is quickly completed, which is adapted to the different depths of the infusion needle 3 inserted into the infusion bottle 1; in addition, each time the infusion needle 3 is changed, the two groups of support rods 59 that are rotated down respectively drive the two groups of arc bars 61 and the movable frame 62 to rotate forward, and the side tilt position of the movable frame 62 squeezes the semicircular balls 67 on both sides respectively, and the two groups of movable rods 65 drive the two groups of clamping blocks 69 to slide close together, and at the same time squeeze the two groups of springs 68, and the two groups of clamping blocks 69 that are close together will squeeze the infusion tube on the lower side of the infusion needle 3, so as to achieve isolation of external air when the infusion needle 3 is pulled out, reduce the flow of air into the infusion tube, and prevent discomfort to the patient.
