Description

Infusion set bottle stopper piercer

technical field

The utility model belongs to the field of medical technology, in particular to a bottle stopper puncturer for an infusion set.

Background technique

Now to the use of the infusion set, only the infusion set bottle stopper puncturer needs to be inserted into the infusion bottle, the air inlet pipe is inserted into the infusion bottle, and the infusion hose is connected to the injection needle to use; adopt the existing infusion set bottle stopper puncturer for infusion, because The puncture needle of the bottle stopper of the infusion set is inserted into the infusion bottle relatively high. After the infusion, some medicines are often left between the needle and the stopper of the infusion bottle, and some infusion medicines are very expensive, which undoubtedly causes a waste of resources.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides an infusion set bottle stopper piercer capable of flushing residual medicine in the infusion bottle.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the infusion set bottle stopper piercer, including the main puncture needle, the flushing puncture needle, the infusion hose and the flushing hose; the top of the main puncture needle is a needle point structure, and the main puncture needle The middle part is a bulging positioning structure, and several leakage holes are opened on the positioning structure, and the lower part of the main puncture needle is provided with a limit ring; the infusion hose is connected to the lower end of the main puncture needle; one end of the flushing hose passes through the infusion hose and It extends upward into the main puncture needle and connects with the needle tip structure of the main puncture needle. The other end of the flushing hose is located outside the infusion hose, and the flushing puncture needle is connected to the other end of the flushing hose. The connection between the infusion hose and the flushing hose There is a seal at the flushing hose, and a control valve is set on the flushing hose; a ring-shaped follicle plate is fixed inside the main puncture needle, and the follicle plate is located below the positioning structure and is sleeved on the outer periphery of the flushing hose; the follicle plate is provided with Two, two follicle plates are arranged side by side up and down.

By adopting the above technical scheme, the utility model has the following beneficial effects: after the infusion is completed, the flushing puncture needle is inserted into the normal saline bottle, and the normal saline flows into the infusion bottle through the flushing hose to flush the infusion bottle, reducing the residual medicine in the bottle waste; the follicle plate arranged in the limiting ring can filter the air bubbles generated in the infusion bottle during infusion.

In summary, using the utility model for infusion can effectively reduce the waste of residual medicine in the infusion bottle after the infusion is completed.

Detailed ways

As shown in Figures 1 and 2, the infusion set bottle stopper piercer of the present utility model includes a main puncture needle 1, a flushing puncture needle 8, an infusion hose 6 and a flushing hose 5; the top of the main puncture needle 1 is a needle point structure, The middle part of the main puncture needle 1 is a swelling positioning structure 2, and the positioning structure 2 is ellipsoidal. The positioning structure 2 is provided with several leakage holes 9. The shape of the leakage holes 9 is rectangular. The lower part of the main puncture needle 1 is provided with The limit ring 3; the infusion hose 6 is connected to the lower end of the main puncture needle 1; one end of the flushing hose 5 passes through the infusion hose 6 and extends upward into the main puncture needle 1 to connect with the needle tip structure of the main puncture needle 1 for flushing The other end of the hose 5 is located outside the infusion hose 6, the flushing puncture needle 8 is connected to the other end of the flushing hose 5, the connection between the infusion hose 6 and the flushing hose 5 is sealed, and the flushing hose 5 is provided with a control valve 7. An annular follicle plate 4 is fixed inside the main puncture needle 1. The follicle plate 4 is located below the positioning structure 2 and the follicle plate 4 is set on the outer periphery of the flushing hose 5. The inner ring of the follicle plate 4 is connected to the flushing tube. The outer walls of the hose 5 are attached to each other; two follicle plates 4 are provided, and the two follicle plates 4 are arranged side by side up and down.

When the utility model is performing infusion, the control valve 7 on the flushing hose 5 is first closed, and then the main puncture needle 1 is inserted into the infusion bottle, so that the bottle stopper is located between the positioning structure 2 and the limit ring 3, and gently pulled downward The main puncture needle 1 makes the lower end of the positioning structure 2 just stuck in the bottle stopper, and then inserts the air inlet pipe into the bottle stopper of the infusion bottle, and the medicine flows into the infusion hose 6 through the leakage hole 9 on the positioning structure 2, and the infusion can be performed. The air bubbles generated during the infusion will be filtered by the follicle plate 4; after the infusion is completed, the residual drug in the infusion bottle needs to be rinsed. When flushing, the flushing puncture needle 8 is inserted into the normal saline bottle, and the normal saline bottle is inserted into the intake pipe, and the control valve is opened. Valve 7, physiological saline is input into the infusion bottle through the flushing hose 5, so as to flush the residual medicine in the infusion bottle, and the medicine after flushing flows into the infusion hose 6 through the leakage hole, and continues to infuse the patient.

This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model belong to the technology of the utility model. protection scope of the program.
