[0002] An infusion set is a medical device used for intravenous infusion, mainly used to infuse liquid medicine or nutrient solution into the patient's body through the vein.
[0003] An infusion set is usually composed of an infusion tube, a needle, a regulator, a filter, and an infusion bottle. When the infusion bottle is hung at a low height, the length of the infusion tube is fixed, so there will be an excessively long section of the infusion tube scattered on the patient. When the patient lies flat on the bed and squeezes the infusion tube, it will cause drug reflux, thereby affecting the drug delivery effect. For this reason, we propose an infusion set.

[0031] The one-way component 6 is arranged on the hollow seat 1 and connected with the driving roller 3 and the reverse component 4 so as to utilize the one-way component 6 to drive the single driving roller 3 to slide.
[0032] The reverse component 4 includes a rotating shaft 41 rotatably arranged on the hollow seat 1, a gear 42 is arranged on the rotating shaft 41, a rack 43 is slidably arranged on the hollow seat 1, the rack 43 and the gear 42 are meshed with each other, and a driving member 5 is arranged on the hollow seat 1 to drive the two racks 43 to slide in opposite directions.
[0033] The driving member 5 includes a worm wheel 51 arranged on the rotating shaft 41 . A worm 52 is rotatably arranged on the hollow seat 1 . The worm 52 and the worm wheel 51 are meshed with each other. A knob 53 is arranged on the worm 52 .
[0034] The one-way component 6 includes strip grooves 61 respectively arranged on the two racks 43, and movable seats 62 are slidably arranged on the two strip grooves 61. The two driving rollers 3 are rotatably arranged on the movable seats 62, and the hollow seat 1 is provided with a limiting member 7 for limiting the movable seat 62.
[0035] The limiting member 7 includes a plurality of limiting holes 71 arranged on both sides of the strip groove 61, and two groups of limiting columns 72 are slidably arranged on both sides of the movable seat 62. The two groups of limiting columns 72 are both matched with the limiting holes 71, and springs 73 are connected to the corresponding surfaces of the two groups of limiting columns 72.
