Description

Anti-bubble infusion apparatus

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an anti-bubble infusion apparatus.

Background

Among medical instruments, a commonly used infusion set is composed of a stopper piercer, a murphy's dropper, a catheter, a flow regulator, a drug solution filter, an intravenous infusion set, and the like. During the use, hang infusion bag at the eminence, the bottle plug puncture ware inserts in the infusion bag, utilize the action of gravity to make liquid flow in the vein through the pipe, when liquid flows through the murphy's burette, when liquid drops into murphy's below liquid level from the top, because the impact force effect of dropping liquid to the liquid level, can bring the air into and form the microbubble in the liquid, can be along with liquid inflow in the vein, and when liquid is lost up, patient or medical personnel do not in time discover, the air can form the air cock in inputing patient's blood vessel, endanger patient's safety.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a prevent transfusion system of bubble, this utility model can prevent that ink fei si burette liquid drop from dropping to the liquid level and bring the air into liquid and form the microbubble and enter into the vein in, when liquid is lost, but the automatic shutdown liquid infusion prevents that the air from getting into and forming the air cock in the blood, endangers patient's health.

In order to achieve the technical purpose, the above technical effects are achieved, and the utility model discloses a realize through following technical scheme:

the utility model provides a prevent transfusion system of bubble, includes pipe, bottle plug puncture ware, first burette, second burette, flow regulator, vein pjncture needle, its characterized in that:

the pipe links together bottle plug puncture ware, first burette, second burette, flow regulator and vein pjncture needle in proper order, be equipped with the foam sacculus in the first burette, the inside lower extreme fixedly connected with anti-bubble device of second burette, anti-bubble device includes rod-shaped structure and water droplet column structure, and rod-shaped structure one end fixed connection is bottom in the second burette, and water droplet column structure is handstand position fixed connection in rod-shaped structure upper end, rod-shaped structure and water droplet column structure integrated into one piece and junction smooth transition, the pipe that goes out liquid hole and second burette lower extreme has been seted up to anti-bubble device lower extreme lateral wall is linked together, it is at least 3 to go out liquid hole quantity.

Further, the diameter of the foam balloon is 4-8 mm.

The utility model has the advantages that: the utility model is provided with the anti-bubble device, the liquid drops are dripped from the upper part and drip on the arc-shaped surface above the anti-bubble device, and flow downwards onto the liquid level of the liquid along the side wall of the anti-bubble device, or the liquid drops splash outwards onto the inner wall of the second dropper, and flow downwards onto the liquid level of the liquid along the inner wall, thereby avoiding the liquid drops directly dripping onto the liquid level, and bringing the air into the liquid to form bubbles to enter the vein due to the action of impact force;

the utility model discloses a be provided with the foam sacculus in the first burette, during the infusion, because the buoyancy effect of liquid upwards lifts up the foam sacculus, makes the normal infusion of liquid, and when liquid was defeated to the end, liquid was to the decline in the first burette, and the pipe entry of first burette below is stopped to the foam sacculus whereabouts to prevent that liquid from continuing to flow downwards, prevent that the air from getting into and forming air cock crisis patient safety in the patient's blood vessel after the liquid was defeated to the end.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, an anti-bubble infusion apparatus includes a catheter 2, a bottle stopper puncture outfit 1, a first dropping tube 3, a second dropping tube 4, a flow regulator 5, and a venipuncture needle 6, and is characterized in that:

catheter 2 links together bottle plug puncture ware 1, first burette 3, second burette 4, flow regulator 5 and vein puncture needle 6 in proper order, foam sacculus 7 is equipped with in the first burette 3, the inside lower extreme fixedly connected with anti-bubble device 8 of second burette 4, anti-bubble device 8 includes rod-like structure 10 and water droplet column structure 11, and 10 one end fixed connection of rod-like structure is bottom in the second burette 4, and water droplet column structure 11 is handstand position fixed connection in 10 upper ends of rod-like structure, and rod- like structure 10 and 11 integrated into one piece of water droplet column structure and junction smooth transition, the pipe 2 that goes out liquid hole 9 and second burette 4 lower extreme has been seted up to the lateral wall of anti-bubble device 8 lower extreme is linked together, go out liquid hole 9 quantity and be 3 at least.

Further, the diameter of the foam balloon 7 is 4-8 mm.

The specific embodiment of the utility model is that: when in use, the bottle stopper puncture outfit 1 is inserted into an infusion bag or an infusion bottle stopper, the flow regulator 5 is opened, so that the liquid medicine flows through the infusion apparatus to discharge air in the infusion apparatus, then the vein puncture outfit 6 is connected into the vein vessel of a patient, when the liquid flows through the first dropper 3, the foam saccule 7 in the first dropper 3 floats upwards under the buoyancy of the liquid, the liquid flows into the second dropper 4 from the conduit 2 below the first dropper 3, the liquid drops drop onto the water drop-shaped structure 11 above the anti-bubble device 8 from the second dropper 4, the upper end of the water drop-shaped structure 11 is an arc surface, the liquid drops drop onto the arc surface or splash onto the inner wall of the second dropper 4 and flow downwards to the liquid level, or flow downwards along the side wall of the anti-bubble device 8, the liquid medicine in the second dropper 4 enters the conduit 2 below from the liquid outlet hole 9 on the side wall of the lower end of the rod-shaped structure 10 of the anti-bubble device 8 and then flows downwards to, thereby preventing the liquid drops from directly dropping on the liquid surface, and air is brought into the liquid to form bubbles to enter the human body along with the liquid medicine due to the action of impact force.

When the liquid medicine is completely infused, the liquid level in the first dropping pipe 3 drops, and the foam balloon 7 is positioned at the bottom in the first dropping pipe 3 due to the action of no buoyancy and blocks the opening of the catheter 2 below, so that the liquid is prevented from continuously flowing, and the safety of a patient in the crisis of air embolism caused by the fact that air enters the blood vessel of the patient after the liquid medicine is infused is prevented.
