Description

Precision film liquid-stopping infusion apparatus of non-o-benzene center positioning automatic liquid-stopping device

Technical Field

The utility model relates to an infusion apparatus, in particular to an infusion apparatus with a non-o-benzene center positioning automatic liquid stopping device (precision film liquid stopping).

Background

At present, infusion devices in the market are various, when people use the infusion devices for infusion, particularly when liquid medicine in an infusion bottle is to be infused to the greatest extent, the infusion needle needs to be pulled out of a human body, if the liquid medicine is not pulled out, the phenomenon of blood return can be caused, and therefore the infusion devices have great harm to the bodies of patients.

In addition, some traditional Chinese medicine injections, fat emulsion injections, biological agents and the like are easy to generate insoluble particles when being combined, more impurities are in the inner parts, the infusion apparatus on the market cannot filter the particle impurities, and once the particle impurities enter the blood of a human body, the health of the human body can be directly influenced. Moreover, insoluble particles of the traditional Chinese medicine injection and the liquid after compatibility can block a precise filtration type infusion apparatus, so that the liquid discharge is difficult.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned not enough of prior art, provide a non-o-benzene center location automatic liquid stopping device (accurate membrane ends liquid) transfusion system.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a non-o-benzene center location automatic liquid stopping device (precision membrane liquid stopping) transfusion system, includes infusion pipeline, puncture ware that adopt non-o-benzene TOTM plasticizer to make, the dropping funnel that adopts non-o-benzene TOTM plasticizer to make, flow rate regulator, luer joint and transfusion needle, the dropping funnel comprises last dropping funnel and lower dropping funnel, its characterized in that: the precise film liquid stopping and bubble preventing device is arranged inside the dropping funnel and comprises a bubble preventing convex tube which is arranged in the middle of the bottom of the lower dropping funnel and protrudes upwards, a plurality of vertically arranged liquid discharging holes are distributed in the side surface of the bubble preventing convex tube, a layer of liquid stopping precise filtering film is arranged on the upper part of the bubble preventing convex tube, and a tube shoulder which is arranged corresponding to the liquid stopping precise filtering film in a hot melting mode is arranged on the inner side of the lower dropping funnel; the novel air-permeable water-proof dropping funnel is characterized in that a transverse coarse filtering membrane which is provided with a layer of hot-melting installation is further arranged at the joint of the upper portion of the lower dropping funnel and the upper dropping funnel, a breathable plug hole is formed in the side face of the bottom of the lower dropping funnel, a ring shoulder portion is arranged on the inner wall of the hole of the breathable plug hole, a breathable water-proof membrane is fixed on the ring shoulder portion, and a movable exhaust plug which is used for compressing and fixing the breathable water-proof membrane on the ring shoulder portion is arranged on one side of. The vent plug is also provided with a sealing gasket at the orifice, so that the vent plug can be stably sealed and fixed in the orifice after being inserted, the breathable waterproof membrane can be breathable and cannot be permeable, and two sides of the breathable waterproof membrane are pressed tightly, thereby forming central positioning.

The utility model discloses a design point has three:

firstly, the problem that the infusion cannot be normally performed due to blockage of insoluble particles of an injection when the injection is prepared by mixing a traditional Chinese medicine injection, a fat emulsion injection, a biological preparation and the like and easily generates the insoluble particles during infusion of a precise filtering infusion set and an infusion pipeline is effectively solved. The utility model discloses the coarse filtration membrane that sets up in the bubble device is prevented to precision film end liquid can filter the great insoluble particle of granule in the liquid medicine earlier, has prevented that this kind of insoluble particle from entering into precision film end liquid and has prevented falling on the end liquid precision filtration membrane of one deck down in the bubble device, prevents that precision filtration film from being blocked up by the insoluble particle.

Secondly, a liquid stopping precise filtering membrane is arranged at the lower part of the liquid stopping and bubble preventing device of the precise membrane, the precise filtering membrane has hydrophilicity, a plurality of micropores are distributed on the surface of the membrane, the precise filtering membrane is in contact with dropping liquid, the micropores are opened, and the dropping liquid penetrates through the automatic liquid stopping layer to carry out transfusion; the precise filtering membrane is separated from the dropping liquid, the micropores are closed, the air is isolated from passing through, and the cavity in the valve body forms negative pressure to stop transfusion. Therefore, the utility model can automatically stop the infusion after the infusion is completed, and prevent the blood return phenomenon of the infusion from occurring.

Third, the utility model discloses a prevent that the outage of flowing back is seted up to the side of bubble protruding pipe, the production of infusion bubble has been prevented effectively to liquid mode under such side, has prevented that the bubble from getting into the transfer line, guarantees infusion safety, and the exhaust operation work load when reducing medical staff's infusion especially when the continuous bottle of infusion, need not to carry out secondary exhaust work, can directly insert the bottle infusion.

Fourth, the utility model discloses a be equipped with the core vent on the ventilative consent, when the infusion, liquid medicine in the dropping funnel is when the infusion is about to end, the liquid level in the fill descends, because itself is sealed in the dropping funnel, the gas vent above-mentioned has the distance from the dropping funnel than longer, in addition the transfer line can be crooked, so liquid medicine in the dropping funnel is hardly totally defeated to the greatest extent with the liquid medicine in the dropping funnel, at this moment, infusion medical personnel can pull out the core vent, let the ventilative consent of dropping funnel accomplish down admit air, and then the liquid medicine in the dropping funnel is smooth downflow accomplishes the infusion completely.

Compared with the prior art, the utility model discloses can block that the liquid medicine in the drip chamber directly gets into the transfer line, the production of bubble has been prevented, and the micropore function is closed when the infusion is about to finish to the end of liquid precise filtration membrane has been combined ingeniously, accomplish the automatic shutdown infusion, the production of "blood return" phenomenon has been prevented, meanwhile, the leakage fluid dram of the side feed liquor of adoption has accomplished the infusion of anti-gas bubble well, overall structure easily realizes, therefore, the clothes hanger is strong in practicability, be worth popularization by a wide margin, infusion medical personnel can pull out the core vent, let the ventilative consent of lower drip chamber accomplish admit air, and then the liquid medicine in the drip chamber is smooth, it is complete to flow the completion infusion, the waste of liquid medicine has been.
