Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The terms "comprises" and "comprising," and any variations thereof, in the described embodiments of the invention, and in the claims and drawings, are intended to cover a non-exclusive inclusion, such as a list of steps or elements.

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

Referring to fig. 1, an embodiment of the present invention provides a fast and accurate exhaust infusion apparatus, which includes an exhaust plastic-steel needle 1, a first infusion hose 3, an exhaust pipe 2, a murphy dropper 4, a flow regulator 5, a second infusion hose 6, a liquid medicine filter 7, and an intravenous infusion needle 8.

Wherein, take exhaust plastic steel needle 1 with be connected with between murphy's formula burette 4 and set up side by side first infusion hose 3 and blast pipe 2, the bottom of first infusion hose 3 stretches into the inside top of murphy's formula burette 4, the bottom of blast pipe 2 stretches into the inside 2/5 ~ 3/5 department of murphy's formula burette 4, the bottom of murphy's formula burette 4 is passed through flow regulator 5 and liquid medicine filter 7 are connected gradually to second infusion hose 6, liquid medicine filter 7 is connected with venous transfusion needle 8. The caliber of the exhaust pipe 2 is smaller than that of the first infusion hose 3.

In one example, the connection of the plastic-steel needle with exhaust 1 with the first infusion hose 3 and the exhaust pipe 2 is hose-sleeved hard pipe.

In one example, the murphy dropper 4 is connected to the first infusion hose 3 such that the first infusion hose 3 is embedded in the murphy dropper 4.

In one example, the connection of the murphy dropper 4 to the exhaust tube 2 is a hose-in-hose.

In one example, the opening size of the exhaust pipe 2 at the exhaust plastic needle 1 is the same as the size of the intravenous infusion needle 8.

The connection of other parts is the same as that of the traditional infusion set.

In an example, the bore of blast pipe is less than the specification and is less than the Murphy's formula dropper end for plastics needle tip department, compares with current transfusion system, the utility model provides an infusion apparatus has following advantage:

(1) to the slow problem of current transfusion system exhaust speed, the utility model discloses be connected the built-in blast pipe in the murphy-type dropper of transfusion system with the liquid medicine, the bore of blast pipe is less than the bore of infusion hose, prevents that the liquid medicine from getting into from the blast pipe upper end, hangs the liquid medicine at this in-process of infusion support and accomplishes the exhaust in the murphy-type dropper, can directly omit this operation of exhausting.

(2) Aiming at the problem that the Murphy dropper of the infusion apparatus is easy to be filled too full, the built-in air conduit between the Murphy dropper and the liquid medicine can plug the exhaust pipe when the liquid medicine reaches the Murphy dropper 2/5-3/5, so that the exhaust of the Murphy dropper stops.
