Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1 and fig. 2 in combination, wherein fig. 1 is a schematic structural view of a preferred embodiment of the anti-drop infusion device provided by the present invention; fig. 2 is a schematic view of a connection structure of the split rotary ring and the cover shown in fig. 1. The anticreep infusion set includes: the cover 1 and the split rotating ring 6.

In the specific implementation process, as shown in fig. 1, a circular through cavity 2 is formed in the bottom of a cover cap 1, an open slot 3 is formed in the side wall of the cover cap 1, a communicating cavity 4 is formed in the bottom of the cover cap 1, two ends of the communicating cavity 4 are respectively communicated with the circular through cavity 2 and the open slot 3, and a semi-arc-shaped clamping groove 5 is formed in the side wall of the cover cap 1 on one side of the open slot 3.

It should be noted that: with the bottle plug puncture ware on the transfusion system through open slot 3 with lead to the chamber 4 slip in circular logical chamber 2 back, rotate the bottle plug puncture ware and make air cleaner on the transfusion system revolve to the joint inslot 5 to pierce transfusion bag mouth at the bottle plug and cover 1 cover on the transfusion bag mouth behind the transfusion bag mouth, two convex sheets on the bottle plug puncture ware erect on leading to chamber 4 both sides interior diapire simultaneously, and the air cleaner joint is in joint inslot 5.

Wherein, the top of the cover cap 1 is fixedly embedded with a rubber gasket 9 to reduce the pressing force between the infusion bag mouths of the cover cap 1.

Referring to fig. 1 and 2, the opening rotary ring 6 is rotatably installed in an annular groove formed in the side wall of the cover 1, a plurality of annularly arranged eccentric rotary cavities 7 are formed in the opening rotary ring 6, a fixing mechanism 8 for clamping the infusion bag head is installed in each eccentric rotary cavity 7, the fixing mechanism 8 comprises a push rod 81, an arc-shaped fixing plate 82 and a spring 83, one end of the push rod 81 is slidably connected with the outer ring wall in the eccentric rotary cavity 7, the other end of the push rod 81 extends into the cover 1 and is fixedly installed with the arc-shaped fixing plate 82, the outer ring wall of the eccentric rotary cavity 7 is gradually reduced in distance from the axis center of the cover 1 along the clockwise direction, the spring 83 is connected in series with the push rod 81, one end of the spring 83 is connected with the outer ring wall of the arc-shaped fixing plate 82, the other end of the spring 83 is fixedly connected with the inner ring wall of the cover 1, and a rubber pad is fixedly, and the outer ring wall of the damping rubber pad is in close contact with the inner ring wall of the opening rotating ring 6.

It should be noted that: rotatory opening swivel becket 6, because the outer lane wall of eccentric rotation chamber 7 is along with the axle center interval of clockwise and shroud 1 littleer and more, consequently promote push rod 81 and make the firm fixed joint of arc fixed plate 82 with the infusion bag mouth, and spring 83 on push rod 81 makes the holding power of arc fixed plate 82 stronger on push rod 81, because the annular groove internal fixation gomphosis that shroud 1 seted up has the damping rubber pad, and the outer lane wall of damping rubber pad and the inner circle wall in close contact with of opening swivel becket 6, consequently difficult the reversal that takes place under the effect of no external force, lead to arc fixed plate 82 pressfitting power to reduce, thereby avoided the patient when the activity of standing up or other people walk about and drag the problem that makes the transfer line drop after the transfer line, the security has been improved.
