Abstract
The utility model belongs to the technical field of medical equipment, and particularly relates to a disposable infusion apparatus capable of automatically discharging air and stopping liquid, wherein the disposable infusion apparatus is applicable to an infusion needle or the intravenous infusion of the human body in cooperation with the infusion needle. The disposable infusion apparatus consists of a bottle stopper puncture outfit protecting cover, a bottle stopper puncture outfit, an air filter, a dropper, a drip chamber, a catheter, a flow adjuster, an automatic air discharging and liquid stopping device and an external cone joint, wherein the automatic air discharging and liquid stopping device consists of an upper cover piece, an air film, a lower cover piece and a liquid stopping film. The automatic air discharge can be realized due to the pressure difference between the air film and the liquid stopping film in the automatic air discharging and liquid stopping device; and due to the hydrophilicity of the liquid stopping film, the air can not enter the disposable infusion apparatus, and when the height of the medicine liquid is lower than the liquid outlet of the automatic air discharging and liquid stopping device, the problem of automatic liquid stopping can be thoroughly solved.
Description
Technical field
This utility model belongs to the medical device technical field.Specifically disposable use automatic vent and automatic liquid-stopping transfusion apparatus, it is supporting for the human vein infusion to be applicable to transfusion needle or entry needle.
Background technology
The entourage often vexedly looks for medical personnel during the fast end of traditional infusion device transfusion, is afraid of the bad accident that therefore causes; When more patient infused end simultaneously, medical personnel often had more visitors or business than one can attend to.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of traditional infusion device, and a kind of disposable use automatic vent and automatic liquid-stopping transfusion apparatus are provided.
This utility model comprises protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, air filter, dropper, dropping funnel, conduit, flow regulator and outer cone joint, between flow regulator and outer cone joint, is provided with automatic vent and automatic liquid-stopping device.
This utility model, described automatic vent and automatic liquid-stopping device are by upper cover plate, air film, lower cover slip and end liquid film and consist of, above upper cover plate, be provided with the feed liquor interface, sidewall at upper cover plate is provided with air through the hole, and the place ahead that sees through the hole at air is provided with air film, between upper cover plate and lower cover slip, arrange and end liquid film, be provided with liquid pass hole above lower cover slip, be provided with out liquid interface below lower cover slip, upper cover plate and lower cover slip are for being tightly connected.
This utility model can be on the inwall of described air through the peripheral upper cover plate in hole, and it is protruding to be provided with 3-6 breast, discharges to guarantee air trapping; On the lower cover slip medial wall adjacent with ending liquid film, be provided with and be no less than 6 and support salient points, with filtration and the smoothly transfusion that guarantees medicinal liquid.
This utility model in automatic vent and automatic liquid-stopping device, utilizes air film and the pressure differential of ending liquid film, realizes automatic vent; Utilize the hydrophilic that ends liquid film, intercept air and enter, when the medicinal liquid height is lower than the liquid outlet of automatic vent and automatic liquid-stopping device, thoroughly solved the automatic liquid-stopping problem.
This utility model, owing between flow regulator and outer cone joint, be provided with automatic vent and automatic liquid-stopping device, thereby increased automatic vent and automatic liquid-stopping function, automatic vent can be realized the automatically removing air of its above infusion pipeline; Automatic liquid-stopping can realize medicinal liquid defeated to the greatest extent the time at the automatic stopping infusion at automatic vent and automatic liquid-stopping device place.Avoided to produce in the infusion process simultaneously the situation that medical personnel that transfusion finishes have more visitors or business than one can attend to.
