Background technology

Transfusion device, as the term suggests be a kind of medical apparatus and instruments of infusing.Its using method is that the liquid be contained in bottle or in transfusion bag is suspended on eminence, the effect of gravity is utilized to make liquid flow into intravenous by the flexible pipe of transfusion device, the size of flow is by the flow regulator be placed on flexible pipe to carry out manual adjustment, and the index of adjustment sees dripping fast (droplet/point) in dropper.Applicant is as the healthcare givers of a line, usually run into child, old man in routine duties rock in infusion process or pull transfusion device, transfusion device upper end connecting plug needle is caused to deviate from capping or the blocking of infusion bottle or transfusion bag, transfusion is caused to interrupt, and there is contaminated hidden danger after coming off in infusion device plug pin, cannot again insert infusion bottle or transfusion bag, affect complete, effective infusion treatment.

Summary of the invention

For above-mentioned deficiency of the prior art, the invention provides a kind of structure simple, easy to use, effectively can fix transfusion device, prevent infusion device plug pin from deviating from infusion bottle or transfusion bag, guarantee the slip-off preventing of safe, complete and effective infusion treatment, pull out transfusion device by mistake.

The technical solution used in the present invention is: a kind of slip-off preventing, pull out transfusion device by mistake, comprise connecting plug needle, dropping funnel, flow regulator and transfusion needle, described connecting plug needle comprises taper contact pin and Plug pin patch bay, taper contact pin is connected to Plug pin patch bay, uniformly on Plug pin patch bay be connected with more than two claws towards taper contact pin, two side of blocking/lid or inner faces drawing clamping in the pawl head of upper clipping claw or be mounted on transfusion bottle/bag.

Further, the connecting hose between described flow regulator and transfusion needle is provided with filter.

Further, the connecting hose between described connecting plug needle and dropping funnel is provided with hollow folder, or the connecting hose between described dropping funnel and flow regulator is provided with hollow folder.

Further, the Plug pin patch bay of described connecting plug needle is arranged the air vent of band venting plug.

Further, described dropping funnel is from aerofluxus dropping funnel.

Again further, hydrophilic film or filter is established in described dropping funnel.

After adopting technique scheme, the invention has the beneficial effects as follows:

1, the taper contact pin of connecting plug needle through the blocking/lid of transfusion bottle/bag enter transfusion bottle/bag interior after, multiple claws that the Plug pin patch bay of connecting plug needle connects are drawn in inwardly, the pawl head of claw is made to stick into side or the inner face of the blocking/lid connecting or be articulated in transfusion bottle/bag, in infusion process, even if the follow-up flexible pipe of transfusion device rocks or pulls, by claw, transfusion device and transfusion bottle/bag are connected firmly, can effectively prevent from causing capping or the blocking that transfusion device upper end connecting plug needle deviates from infusion bottle or transfusion bag, once complete safe and effective infusion treatment, improve transfusion efficiency and safety,

2, the connecting hose between flow regulator and transfusion needle is provided with filter, establishes filter in dropping funnel, can microgranule effectively in filtering liquid medicine, and the harm avoiding or reduce microgranule to cause patient, is conducive to reducing infusion reaction and side effect;

3, the connecting hose between connecting plug needle and dropping funnel is provided with hollow folder, or the connecting hose between described dropping funnel and flow regulator is provided with hollow folder, hollow folder can block the medicinal liquid conveying in flexible pipe at any time, is convenient to the adjustment operation to amount of infusion or interruption transfusion operation;

The Plug pin patch bay of 4, connecting plug needle is arranged the air vent of band venting plug, dropping funnel be from aerofluxus dropping funnel, establishes hydrophilic film in dropping funnel, all can effectively get rid of or absorb the air in infusing, raising infusion safety.

Transfusion device of the present invention adopts the Plug pin patch bay band claw of connecting plug needle to draw fixing transfusion bottle/bag in, effectively can fix transfusion device, prevent infusion device plug pin from deviating from infusion bottle or transfusion bag, guarantee safe, complete and effective infusion treatment.
