Abstract
The utility model provides a no-residual-liquid infusion apparatus and belongs to the technical field of infusion apparatuses. The no-residual-liquid infusion apparatus solves the problem that after liquid of a liquid stopping infusion apparatus is stopped, vein blood is prone to flowing back to the infusion apparatus; and the infusion apparatus cannot increase pressure to enable backflow blood and residual liquid medicine to be conveyed to the human vein so as to waste liquid medicine and cause side effects on the human body. The no-residual-liquid infusion apparatus comprises an infusion apparatus pipeline, a puncture outfit, a drip chamber, a liquid-stopping filter, a flow adjustor and an infusion needle are sequentially arranged on the infusion apparatus pipeline, and an air inlet device for removing residual liquid in the pipeline is arranged on the infusion apparatus pipeline at the lower portion of the liquid-stopping filter or at the back of the liquid-stopping filter. The no-residual-liquid infusion apparatus has the advantages of being simple in structural principle, visual, practical and suitable for liquid-stopping infusion apparatuses, avoiding liquid residues, solving the blood return problem of the existing infusion apparatus and the like.
Description
Technical field
This utility model belongs to the transfusion device technical field, refers in particular to a kind of noresidue fluid dispenser.
Background technology
Along with the continuous development of infusion techn and the raising day by day of clinical requirement, end automatically the liquid transfusion device with it when the fast infusion of liquid is intact, can end liquid automatically, avoid air admission venous characteristics to replace general infusion set gradually automatically.Automatically ending the liquid transfusion device is to have utilized under the atmospheric pressure effect, and liquid flows into a thinner infusion tube and forms hydrostatic pressing in the bottle, and when hydrostatic pressing during greater than venous pressure, the flow of liquid in the bottle is gone into vein.When the fast infusion of medicinal liquid is intact, under the tensile effect of filter membrane surface that ends automatically in the liquid device, venous pressure and gravitative pressure active force and filter membrane equalization of strain in the transfusion tube wall, it is atmospheric pressure, hydrostatic pressing, make medicinal liquid rest in the transfusion device under the comprehensive function power of human vein, reach the function of ending liquid automatically, but this transfusion device is after ending liquid, because of reducing of hydrostatic pressing, cause venous blood to flow backward in the transfusion device easily, and this transfusion device can't be delivered to human vein with blood and the residual medicinal liquid that flows backwards by increasing pressure, has therefore caused the waste of medicinal liquid also human body to be caused some harmful effects.
Summary of the invention
The purpose of this utility model provides a kind of being applied to only on the liquid transfusion device, and medicinal liquid is carried thoroughly, noresidue, the noresidue fluid dispenser avoiding or can in time stop transfusion device blood back phenomenon to produce.
The purpose of this utility model is achieved in that
The noresidue fluid dispenser, comprise the transfusion device pipeline, set gradually perforator, dropping funnel on the described transfusion device pipeline, end liquid filter, flow regulator and transfusion needle, it is characterized in that: the described transfusion device pipeline that ends the liquid filter bottom or end after the liquid filter is provided with air intake installation, and air intake installation is by air inlet seat, seal cover and end the liquid film sheet and form.
In above-mentioned noresidue fluid dispenser, described air inlet seat can with end that liquid filter becomes one or separately with end liquid filter and be connected or be connected and end on the liquid filter transfusion device pipeline afterwards.
Described ending in the liquid filter is provided with the filtrate film, and air inlet seat is plugged on ending on the liquid filter of filtrate film below.
In above-mentioned noresidue fluid dispenser, described seal cover one end is hinged on the air inlet seat, and seal cover is provided with capping.
This utility model gives prominence to compared to existing technology and beneficial technical effects is:
This utility model is to have adopted after only the liquid transfusion device ends liquid, transfusion device in the inactive liquid section ends the air intake installation that air admission is set on the liquid filter pipeline, increased pressure, make the liquid smooth delivery of power finish, be provided with only liquid film simultaneously in the air intake installation, prevent the medicinal liquid water clock, after ending liquid, in time open air intake installation, can finish the conveying of residual liquor, if can not in time open, produce the blood back phenomenon, by opening air valve, can carry the Huis' vena systemica to fight the blood and the medicinal liquid that flow backwards, this utility model structural principle be simple, directly perceived practical, be applicable to and end on the liquid transfusion device, make the medicinal liquid noresidue, solved existing transfusion device blood back phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is this utility model partial structurtes sketch maps.
The specific embodiment
This utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
The noresidue fluid dispenser, comprise transfusion device pipeline 1, set gradually perforator 2, dropping funnel 3 on the described transfusion device pipeline, end liquid filter 4, flow regulator 5 and transfusion needle 6, it is characterized in that: describedly end the liquid filter bottom or end the air intake installation 7 that transfusion device pipeline after the liquid filter is provided with residual liquid in the pipeline.
Above-mentioned air intake installation comprises air inlet seat 70 and seal cover 71, and described air intake installation is plugged on to end the liquid filter bottom or be connected and ends on the liquid filter transfusion device pipeline afterwards, and described air intake installation is provided with only liquid film sheet 72.
Above-mentioned air intake installation only is plugged on, and the liquid filter bottom is: end in the liquid filter being provided with filtrate film 40, air inlet seat is plugged on ending on the liquid filter of filtrate film below.
Above-mentioned air inlet seat with end the liquid filter one and be connected.
Above-mentioned air inlet seat is parts in a tubular form.
Above-mentioned seal cover one end is hinged on the air inlet seat, and seal cover is provided with capping 73.
Operation principle of the present utility model is: when medicinal liquid is in static shape in ending the liquid transfusion device, at this moment, venous pressure, medicinal liquid gravity, atmospheric pressure all are in balanced shape, but air intake installation by the transfusion device pipeline setting switch after having the ending the liquid filter bottom or end liquid filter of medicinal liquid, make and under the atmospheric pressure effect, make medicinal liquid be delivered to vein by air admission.
The foregoing description is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
