Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.

As depicted in figs. 1 and 2, the utility model provides a kind of infusion anti-drop device, including arc fixture 5, flexibility Connector 2 and snap ring 4, the arc fixture 5 are fixed on infusion bottle 1, and the snap ring 4 is equipped with notch, described Snap ring 4 is set on the perfusion tube 3 of infusion apparatus, and described 2 one end of flexible connecting member is connect with the snap ring 4, another End is connect with the arc fixture 5；The arc fixture 5 includes symmetrically arranged left clamping part and right clamping part, the left folder Hold portion and right clamping part include interconnecting piece 11, the handle 9 to extend back from the interconnecting piece 11, from the interconnecting piece 11 forward The arc clamping jaw 7 of extension, the arc clamping jaw 7 are matched with the shape of the infusion bottle 1, the left clamping part and right clamping part Interconnecting piece 11 it is hinged by hinged shaft 10, torsional spring 8 is arranged on the hinged shaft 10, the both ends of the torsional spring 8 extend respectively backward It is fixed on corresponding handle 9.

Needle for inserting bottle 6 is fixed on infusion bottle 1 by arc fixture 5, flexible connecting member 2 and snap ring 4 by the utility model On, to prevent the risk that needle for inserting bottle 6 is deviate from from infusion bottle 1 caused by a variety of causes in infusion process, reduce patient's pain Bitter and infected wound risk, while avoiding wasting perfusion tube 3 because needle for inserting bottle 6 is fallen on the ground, and needs replacing infusion apparatus Interior medical fluid, so as to reduce the cost of use of patient.

Wherein, 2 one side of flexible connecting member can prevent needle for inserting bottle 6 from falling on the ground, on the other hand when needle for inserting bottle 6 is de- When falling, traction force downward to infusion apparatus when patient's movement arm can be buffered, to avoid pullling wearing on patient's arm Pricker head reduces patient suffering and avoids re-starting puncture.Preferably, the flexible connecting member 2 is rubber band or stretch cord Or spring wire.

In the utility model, the arc fixture 5 includes symmetrically arranged left clamping part and right clamping part, the left clamping Portion and right clamping part include interconnecting piece 11, the handle 9 to extend back from the interconnecting piece 11, prolong forward from the interconnecting piece 11 The arc clamping jaw 7 stretched, the arc clamping jaw 7 are matched with the shape of the infusion bottle 1, the left clamping part and right clamping part Interconnecting piece 11 is hinged by hinged shaft 10, and torsional spring 8 is arranged on the hinged shaft 10, and the both ends of the torsional spring 8 extend solid respectively backward It is scheduled on corresponding handle 9.

By pressing inward against handle 9 with hand, so that two arc clamping jaws 7 outwardly open, then arc clamping jaw 7 is stuck in defeated On liquid bottle 1, hand is unclamped, under the elastic reaction of torsional spring 8, two 7 reversing resets of arc clamping jaw, two arc clamping jaws 7 are just tight Tightly it is clamped on infusion bottle 1；Handle 9 equally is pressed inward against with hand, so that two arc clamping jaws 7 outwardly open, it can be by arc Clevis pawl 7 takes out from infusion bottle 1.
