Embodiment Construction

[0009] Combine below figure 1 Describe in detail the details and working conditions of the specific device proposed according to the present invention.

[0010] like figure 1 As shown, the stopper piercer (1), the upper conduit (2), the dropper (3), the drip funnel (4), the anti-blood return filter (6), and the lower conduit (7) of the automatic exhaust anti-blood return infusion set , the regulator (8), the infusion needle (9) and the terminal sheath (10) are connected in sequence to form the basic whole of the infusion set. The dripping funnel (4) has at least one exhaust window (5).

[0011] The anti-exhaust blood infusion device of automatic exhaust that the present invention proposes works like this, after the bottle stopper puncturer (1) is inserted into the liquid medicine bottle, the gravity action medicine liquid of the liquid flows into the dripping funnel (3) through the upper conduit (2) dropper (3) 4). Because the terminal sheath (10) closes the terminal, the ...

Abstract

The invention relates to an automatic exhausting anti-blood backflow infusion apparatus, which comprises a bottle cork puncture outfit, a dropping funnel, an anti-blood backflow filter, a lower catheter, an infusion needle and the like. The automatic exhausting anti-blood backflow infusion apparatus is characterized in that: the dropping funnel is at least provided with an exhausting window sealedby an air filtering membrane; and the lower end of the dropping funnel is provided with a terminal sheath of the anti-blood backflow filter to seal a terminal. When the infusion apparatus operates, liquid medicine flows into the dropping funnel under the action of gravity, and redundant air is discharged from the exhausting window; and the terminal sheath is removed during infusion, and the liquid medicine flows out of the terminal. If the liquid medicine is used up without being processed in time, the anti-blood backflow filter blocks the air to enable the liquid medicine to stop flowing andprevent the air from entering the lower catheter to achieve the aim of blood backflow prevention.

Description

technical field [0001] The invention relates to the category of medical equipment, and is an automatic exhaust and anti-return blood infusion set. Background technique [0002] Since the advent of the infusion set, it has been difficult to ventilate during operation, and the liquid medicine in the liquid bottle has not been replenished in time, and the phenomenon of blood returning to the liquid has not been solved. Due to the difficulty of exhaust, not only increases the workload of nursing staff, but also has potential safety hazards. The phenomenon of back blood not only causes the panic of the patient, but also all can cause a lot of trouble and danger once thrombus blocks the needle tube and a large number of air bubbles enter the down catheter. [0003] In order to solve these problems, many patents and products of anti-bubble and anti-reflux infusion sets have been released in recent years. But so far none of the products can be popularized and applied. The main rea...
