Abstract

The invention discloses a multifunctional safety infusion apparatus, comprising an air inlet pipeline and an infusion pipeline, wherein the two pipelines are respectively provided with a blood-back-prevention filtering dropping speed display device; the display device is externally provided with a display tube (2), and is internally provided with a backoff type blood-back-prevention cap (4), and the lower edge of the cap is tooth-shaped; a height limiting fixer (3) is arranged above the blood-back-prevention cap (4); the lower part of the display tube (2) is provided with a convex filter (6);and the filter (6) is internally provided with filter paper (7). In the multifunctional safety infusion apparatus, quadruple filtering and double blood back prevention are achieved, the structure is simple, the functions are more, the safety of infusion is improved, the labor intensity of medical staffs is reduced and the disputes between a doctor and a patient are reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a multifunctional safety infusion set. Background technique [0002] Blood return in the infusion and harmful substances in the air entering the medicinal solution are two major drawbacks in the infusion. At present, the anti-reflux infusion sets and precision infusion sets with filtering function on the market have single functions and have relatively large defects. Anti-reflux infusion set uses a floating block or ball to block the output tube with the downward movement of the infusion liquid, so that the residual fluid pressure in the infusion set overcomes the patient's venous pressure to achieve the purpose of preventing blood return. However, it is not easy to prevent the liquid level from moving down when the infusion set is tilted or shaken, and the anti-bleeding purpose cannot be achieved. The precision infusion set uses a filter membrane to filter the insoluble particle residues in...
