Abstract
The utility model discloses a self -bleeding of nontoxic environmental protection ends accurate transfusion system of liquid, including the device that admits air that connects gradually, bottle stopper puncture device, go up pipe, burette, dropping funnel, downcomer, flow regulator, precision filter, outer cone joint, still include self -bleeding pipe device, automatic liquid -stopping device, self -bleeding pipe device set up in the dropping funnel and with pipe connection down, the automatic liquid -stopping device is connected between downcomer and flow regulator. The utility model has the advantages that setting up the automatic liquid -stopping device on the transfusion system pipeline, can playing automatic liquid -stopping's effect, bring up to 2.0 mu m particles to the filter residue grade of liquid medicine simultaneously by a wide margin, the self -bleeding in the dropping funnel manages the device, can play self -bleeding's effect, prevents the production of bubble and gathers, and the automatic discharge air does not need the artifical exhaust of repetition, and the discharge velocity is fast, can eliminate the bubble in the liquid and guarantee not weeping, tubular product does not contain the toxicant, uses safer, environmental protection as third class medical instrument.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of transfusion device.
Background technology
On clinical medicine, widely used transfusion device is gravity type transfusion system, in actual use, could be normally patient fluid infusion after medical personnel need to extrude the air in dropping funnel discharge infusion pipeline and dropping funnel.In infusion process, also will observe medicinal liquid situation, when dripping off soon, medicine bottle will be changed in time, otherwise air enters in the downcomer below dropping funnel, in downcomer, produce bubble.If bubble inputs human body with medicinal liquid, threaten to the personal safety of patient, there will be severe stupor or even death.And bubble will be drained, medical personnel operate pretty troublesome.
The liquid medicine filter of the general infusion set of current Clinical practice, adopt fiber speed filter membrane, the classification of accurate aperture can not be carried out, use exceedes a certain amount of or meets soda acid, easy generation fibre shedding, and the microgranule of particle diameter more than 15 μm in main filtering medicinal liquid, lower to the rejection rate of less than 15 μm microgranules, therefore, existing transfusion device can not meet the functional requirement of automatic vent and automatic liquid-stopping when infusing.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model is to provide the precision infusion set that a kind of automatic vent stops liquid, energy automatic vent and automatic liquid-stopping during transfusion, and without toxicant, use safety.
Technical scheme: a kind of automatic vent of asepsis environment-protecting stops liquid precision infusion set, comprise the air inlet device, bottle plug puncture unit, upper conduit, dropper, dropping funnel, downcomer, flow regulator, accurate filter, the outer cone joint that connect successively, also comprise automatic vent pipe device, automatic liquid-stopping device, described automatic vent pipe device to be arranged in described dropping funnel and to be connected with described downcomer, and described automatic liquid-stopping device is connected between described downcomer and described flow regulator.
Described automatic liquid-stopping device comprises inlet, upper casing, lower casing, liquid outlet, only liquid film, air-filtering membrane, steam vent, described steam vent is opened in described upper casing, described air-filtering membrane to be fitted described steam vent at described upper casing inwall, and described only liquid film is placed between the faying face of described upper casing and described lower casing.
Described upper conduit, described downcomer are thermoplastic elastomer (TPE) TPE extrusion moulding pipe, have the characteristic of soft-touch, good weatherability and nontoxic, environmental protection, safety, and product resilience are good, in packaging and use procedure, not easily broken pipe occurs.
Described only liquid film is double-deck poly (ether sulfone) film, effectively can be greater than the microgranule of 2.0 μm in filtering liquid medicine.
Beneficial effect: compared with prior art, the utility model has the advantages that and automatic liquid-stopping device is set on transfusion device pipeline, the effect of automatic liquid-stopping can be played, 2.0 μm of microgranules are significantly brought up to the filtering residue grade of medicinal liquid simultaneously, the automatic vent pipe device in dropping funnel, self-bleeding effect can be played, prevent the generation of bubble and gather, automatic air-out, not needing repetitive manual aerofluxus, exhaust velocity is fast, can eliminate the bubble in liquid and ensure no leakage; Tubing, not containing toxicant, uses safer, environmental protection as the 3rd class medical apparatus and instruments.
