Abstract
The invention relates to an infusion apparatus low in contamination and easy to operate, and belongs to the technical field of medical equipment. The infusion apparatus low in contamination and easy to operate is characterized in that the infusion apparatus is mainly composed of a puncture air intake and water stopping device, a limiting liquid stopping device, a pipeline air exhausting device, an intravenous needle air exhausting and liquid stopping device and parts of conventional parts of the infusion apparatus; the puncture air intake and water stopping device, the pipeline air exhausting device and an air exhausting and water stopping membrane of the intravenous needle air exhausting and liquid stopping device achieve the effects of automatic air exhausting and liquid penetration stopping; the limiting liquid stopping device and a liquid penetrating and air stopping membrane of the pipeline air exhausting device achieve the effects of penetrating liquid and stopping gas from penetrating through. The liquid charging process and the air exhausting process of the infusion apparatus are both completed automatically by the infusion apparatus; due to the stopping of the air exhausting and water stopping membrane of the intravenous needle air exhausting and liquid stopping device, microorganisms in the air of a ward cannot enter an interior system of an intravenous needle easily, and contamination caused before products are used is lowered.
Description
Technical field
The present invention relates to low stain ease of Use type transfusion device, belong to technical field of medical instruments.
Background technology
Transfusion device is widely used clinically, conventional infusion device is when inserting infusion bottle, easily there is the place's leakage of perforator air inlet film, cannot accurately control liquid level in dropping funnel, in dropping funnel and pipeline liquid easily flow empty after gas enter lower end pipeline, in infusion process easily there is gas and be difficult to thoroughly drain in lower end pipeline, and before the patient's vein that extremely punctures after transfusion device insertion infusion bottle, intravenous needle end is opening-wide state, microorganism in ward air not easily enters the built-in system of intravenous needle, bring the potential safety hazard of patient infection, and due to conventional infusion device puncture vein before overall process and need medical personnel to pay close attention to before changing dressings, great inconvenience is brought to the work of medical personnel.
Summary of the invention
The invention provides low stain ease of Use type transfusion device, the built-in system that it has that the liquid fill of transfusion device and exhaust process are that transfusion device completes automatically, microorganism in ward air not easily enters intravenous needle, reduce product use before pollution and feature easy and simple to handle.
The technical solution adopted for the present invention to solve the technical problems is: transfusion device stops liquid device and transfusion device part conventional components composition primarily of puncture air inlet waterproofing device, spacing only liquid device, tubes rows device of air, intravenous needle aerofluxus.Wherein, puncturing, to stop liquid device be order arrangement from top to bottom from infusion bottle to intravenous needle direction for air inlet waterproofing device, spacing only liquid device, tubes rows device of air and intravenous needle aerofluxus.Puncture air inlet waterproofing device at least comprises perforator, perforator aerofluxus blocks water film, spacing only liquid device at least comprises spacing hole aerofluxus and to block water film, dropping funnel lid, cavity, funnel-form dropper, the transparent liquid gas barrier film of spacing only liquid device, position-limiting tube, position-limiting tube port and dropping funnel, wherein position-limiting tube and dropping funnel lid as a whole, funnel-form dropper and dropping funnel lid are that interference viscose glue assembles, dropping funnel and dropping funnel lid are also for interference viscose glue assembles, the aerofluxus of transparent liquid gas barrier film and tubes rows device of air that tubes rows device of air at least comprises tubes rows device of air blocks water film, intravenous needle aerofluxus stops liquid device and at least comprises intravenous needle, protective sleeve and intravenous needle aerofluxus stop liquid device aerofluxus and to block water film, and protective sleeve and intravenous needle are that interference is without bonding cooperation, it is close fit that intravenous needle aerofluxus stops the block water periphery of film and protective sleeve of liquid device aerofluxus.Perforator aerofluxus block water film, spacing hole aerofluxus block water film, tubes rows device of air block water film, intravenous needle aerofluxus of aerofluxus stop liquid device aerofluxus resistance water film surface and there is hydrophobicity, its film material average pore size is no more than 0.55 μm, spacing only the transparent liquid gas barrier film of liquid device, the transparent liquid gas barrier film surface of tubes rows device of air have hydrophilic, and its film material average pore size is no more than 10 μm.Aerofluxus due to each position of the transfusion device film that blocks water has gas and can freely pass through and the effect that liquid cannot pass through, the transparent liquid gas barrier film at each position of transfusion device has liquid can freely be passed through and the effect that gas cannot pass through, thus reach liquid automatic filling transfusion device under gravity, and the object that gas is discharged automatically, and to block water the stop of film owing to there being intravenous needle aerofluxus to stop liquid device aerofluxus, microorganism in ward air not easily enters the built-in system of intravenous needle, reduce the pollution before product use, thus greatly reduce the risk of patient infection.
