Problems solved by technology

[0002] Disposable infusion sets used clinically in clinical units of various domestic medical institutions are mainly composed of bottle stopper puncturer protective cover, bottle stopper puncturer, air filter, infusion hose, dropper, dropper, flow regulator, liquid medicine filter The product is composed of a device and an intravenous infusion needle. During the clinical use of this product, especially when the liquid medicine is about to run out, the family members of the patient are very nervous. Into the lower hose under the drip funnel, in order to continue the infusion, the nursing staff can only exhaust the air by wrapping the lower hose around the fingers, which is very inconvenient to operate, or filter the medicine solution from the medicine solution by unscrewing the infusion needle seat It is discharged from the joint of the device, which not only wastes the medicine solution but also makes it easy for germs to invade and cause infusion infection
Although there are self-stopping liquid infusion sets on the market, the effect of self-stopping liquid cannot be truly reflected in the clinical use of these products

Embodiment 1

[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 Among them, the present invention consists of a bottle stopper piercer protective cover (1), a bottle stopper piercer (2), an air filter membrane (3-1), an air plug (4-1), an upper hose (5), and a dripping funnel cover (6), latex cap (7), self-stop liquid valve, upper drip funnel (8), lower drip funnel (11), lower hose (12), flow regulator (13), liquid medicine filter (14) It consists of an intravenous infusion needle (15), the bottle stopper piercer protective cover (1) is set on the bottle stopper piercer (2), and the air plug (4-1) tightly presses the air filter membrane (3-1) on the bottle stopper In the air inlet of the piercer (2), the bottle stopper piercer (2), the upper flexible pipe (5), the drip funnel cover (6), the upper drip funnel (8), the lower drip funnel (11), the lower flexible pipe ( 12), the liquid medicine filter (14) is connected sequentially, the latex cap (7) is sleeved on th...

Embodiment 2

[0032] Such as Figure 6 Among them, the structure of the present embodiment 2 is basically the same as that of the embodiment 1, the difference is that the plastic steel needle is used, the dripping funnel cover (6) is a self-exhausting device, and the liquid medicine filter is placed at the lower end of the flow regulator (13). (14) becomes a precision filter (14a), and a liquid stop clip (17) and a Luer connector (16) are added, and others are the same as figure 1 Similarly, the plastic steel needle (2) is formed by bonding the liquid outlet base (2c), the liquid inlet cap (2b) and the air inlet needle tube (2a); Insert the needle (2) into the bottle stopper of the medicine bottle hanging upside down, the medicine liquid will automatically enter the dripping funnel to the limit position (6a), the liquid level will not rise any more, pinch down the hose (12), and it will float from the liquid stop valve to the upper drop The protrusion (8a) position of bucket (8) does not r...

Embodiment 3

[0035] Such as Figure 7 Among them, the structure of the present embodiment 3 is basically the same as that of the embodiment 2, and the difference is that the plastic steel needle becomes a plastic needle, and the cork piercer (2), exhaust hose (18), air filter (19) Instead, a liquid storage device (20), a latex cap (7-2), a vent plug (21) and a liquid stop clip (17-1) are added to the lower part of the upper hose; when in use, pull out the plastic needle guard Set (1), insert the plastic needle (2) into the bottle stopper of the upside-down medicine bottle, close the flow regulator (13), and the medicine liquid will automatically enter the liquid storage device (20) and the dropping funnel to the limit position (6a), After the liquid level no longer rises and the medicinal liquid reaches the specified capacity, close the water stop clamp (17-1), pinch down the hose (12), and float from the liquid stop valve to the protrusion (8a) of the upper dripping funnel (8) And can no...

Abstract

The invention discloses a disposable automatic liquid stopping infusion set which comprises a bottle stopper puncture device protecting sleeve, a bottle stopper puncture device, an air filtering film, an air plug, an upper soft pipe, a drip bucket cover, a latex cap, an upper drip bucket, an automatic liquid stopping valve, a lower drip bucket, a lower soft pipe, a flow adjuster, a medicine liquid filter and an intravenous infusion needle. The disposable automatic liquid stopping infusion set is characterized in that the automatic liquid stopping valve comprises a through hole floater and a water stopping film piece, the water stopping film piece comprises a frame and a middle thin layer, the water stopping film piece is embedded into the bottom of the through hole floater, the automatic liquid stopping valve is arranged in the lower drip bucket, and the automatic liquid stopping valve can be filled with medicine liquid and then float. When a small amount of medicine liquid exists in the drip bucket during an infusion process, a liquid outlet of the lower drip bucket is automatically sealed, air is prevented from entering the lower soft pipe so that the problem that workload is increased due to the fact that air enters the lower soft pipe can be avoided, and medical disputes caused by medical accidents can be avoided.
