Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-2, the self-plugging infusion apparatus of the utility model comprises a Mortiered dropper, a first connecting pipe 2 and a second connecting pipe 8 respectively connected with two ends of the Mortiered dropper, wherein one end of the first connecting pipe 2, which is far away from the Mortiered dropper, is connected with a bottle inserting needle, one side of the first connecting pipe 2 is communicated with an exhaust pipe 3, one end of the second connecting pipe 8, which is far away from the Mortiered dropper, is connected with an infusion needle 10, and the outer side of the second connecting pipe 8 is sleeved with a flow controller 9;

a funnel 4 is fixedly arranged in the Morph dropper, the large end of the funnel 4 is close to the first connecting pipe 2, the small end of the funnel 4 is connected with a conduit 6, and a floating self-plugging piece 5 is arranged in the funnel 4 and used for controlling the opening and closing of the funnel 4 and the conduit 6; the funnel 4 is positioned at two thirds of the height of the Mortierella dropper and the length of the conduit 6 is one third of the Mortierella dropper.

In order to improve the tightness, the self-plugging piece 5 comprises a guide rod 53 inserted in the guide pipe 6 and a plugging block 52 fixedly arranged at the top of the guide rod 53, the plugging block 52 is in a round table shape, the diameter of the small end of the plugging block 52 is smaller than that of the small end of the funnel piece 4, the lower end face of the plugging block 52 is tightly attached to the upper end face of the funnel piece 4, and the guide rod 53 and the plugging block 52 are made of materials which meet medical standards and are smaller than the density of liquid medicine.
