2. The intravenous therapy anti-drop securement device of claim 1, wherein: the top plate (18) is arc-shaped, and one side of the top plate (18) close to the bayonet (7) extends towards the bayonet (7).
3. The intravenous therapy anti-drop securement device of claim 2, wherein: the stiffness coefficient of the second spring (10) is larger than that of the first spring (6).
4. A method of using the intravenous therapy anti-slip fastening device of claim 3, wherein: the method comprises the following steps:
s1, when the infusion needle is used, the infusion needle is inserted into an infusion bottle, then the frame (1) is held to enable the infusion needle to move into the bayonet (7), then the infusion tube below the infusion needle is pulled downwards to enable the infusion needle chuck to descend, at the moment, the driving assembly cancels driving of the limiting plate (2), at the moment, the compressed first spring (6) continuously releases acting force to enable the limiting plate (2) to move, so that the pair of limiting plates (2) move close to each other, and further the bottleneck is clamped;
S2, if the infusion tube is pulled, the infusion needle chuck is pulled to prop against the frame (1) and the limiting plate (2) to enable the infusion tube chuck and the limiting plate to move downwards, but the infusion bottle is hung at a high position and cannot move downwards, and at the moment, the limiting plate (2) is blocked with the bottle neck and cannot move, so that the whole infusion needle cannot move, the infusion needle cannot be separated from the infusion bottle, and anti-falling is realized;
S3, when the infusion bottle needs to be replaced, the driving assembly drives the pair of limiting plates (2) to move away from each other, meanwhile, the first springs (6) are compressed to enable the first springs to deform to generate acting force, the pair of limiting plates (2) leave the bottleneck, clamping of the bottleneck is canceled, then the frame (1) can be separated from the infusion bottle and the infusion needle, replacement of the infusion bottle can be carried out, follow-up anti-falling can be continued, the whole anti-falling operation of the infusion needle is simple and easy, and the limiting plates (2) can be suitable for clamping of infusion bottles of different sizes through the expansion and the contraction of the first springs (6), so that the whole device is stronger in applicability.
