Full automatic infusion set

Abstract

The invention belongs to the field of medical equipment, and particularly relates to a full automatic infusion set used for clinical intravenous infusion. The full automatic infusion set comprises a bottle stopper puncture device, a first transfusion tube, a drip chamber, a second transfusion tube, a liquid medicine filter, a third transfusion tube, a Luer and an intravenous infusion needle which are connected in sequence, wherein a flow regulator is installed on the third transfusion tube; an exhaust device is arranged in the drip chamber; the exhaust device comprises an exhaust seat, an exhaust pipe and a nut cap; the bottom of the exhaust seat is fixed on a liquid dripping opening formed at the bottom end of the drip chamber, and is in close fit with the liquid dripping opening; the hollow exhaust pipe communicated with the liquid dripping opening is arranged in the exhaust seat; a liquid inlet gap is formed between the exhaust pipe and the exhaust seat; liquid inlet slots are formed on the side walls between the exhaust pipe and the exhaust seat; the nut cap is arranged at the top of the exhaust seat; the nut cap is fastened on the exhaust seat; and at least two exhaust grooves are formed on the side wall of the nut cap. The full automatic infusion set with a reasonable structure can achieve automatic exhaust, automatic liquid filling and automatic liquid stopping when in use rather than inverting or squeezing the drip chamber, is fast and convenient to use, and is safe and reliable.

Description

technical field [0001] The invention relates to a fully automatic infusion set for clinical intravenous infusion, which belongs to the field of medical equipment. Background technique [0002] At present, when hospitals perform intravenous infusions on clinical patients, disposable infusion sets are generally used, which plays a beneficial role in preventing cross-infection between patients. However, this disposable infusion set also has shortcomings, that is, it needs to squeeze or invert the dripping funnel during use, otherwise it will easily form a mixture of gas and liquid, and the gas-liquid mixture will quickly enter the infusion tube below the dripping funnel In the pipeline, air bubbles will form during infusion, which will cause harm to patients. Therefore, during infusion, the medical staff must completely discharge the air bubbles in the infusion catheter before infusion; It is very troublesome to deal with after entering the lower catheter and changing the bott...

Problems solved by technology

In the course of clinical infusion treatment, it is often necessary to infuse multiple bottles of medicinal liquid, but after the first bottle of medicinal liquid is infused, the general infusion set has no automatic liquid stop function, and the infusion line will be damaged due to the failure to change the bottle in time. The liquid medicine flows out, caus
