Abstract
The utility model discloses a residue-free liquid infusion apparatus which comprises an infusion apparatus pipeline. A puncture apparatus, a drip funnel, a liquid-stop filter, a flow regulator and an infusion needle are arranged on the infusion apparatus pipeline in sequence and are communicated with one another, the liquid-stop filter is arranged on the drip funnel, and an air inlet unit is arranged between the liquid-stop filter and the flow regulator. The residue-free infusion apparatus is simple in structure and principle, visual, practical and suitable for liquid-stop infusion apparatuses. Further, medicine soup is not left on the liquid infusion apparatus, and the problem of blood return when an existing infusion apparatus is used is solved.
Description
Technical field
This utility model belongs to the transfusion device technical field, specifically is 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, the characteristics of avoiding air to enter vein have automatically replaced general infusion set gradually.It is to have utilized under the atmospheric pressure effect that film ends the liquid transfusion device, 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 liquid in the bottle flows into vein.When the fast infusion of medicinal liquid is intact, automatically end under the effect of the filter membrane surface tension force 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.Utility model content the purpose of this utility model provides a kind of film that is applied to ends 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
A kind of noresidue fluid dispenser, comprise the transfusion device pipeline, successively with perforator, dropping funnel, only liquid filter, flow regulator and transfusion needle connection, it is characterized in that: ending between liquid defecator or the flow regulator on the described dropping funnel is provided with air intake installation on the described transfusion device pipeline.
Described air intake installation directly with dropping funnel on the liquid defecator that ends is connected or is arranged on and end on the liquid defecator transfusion device pipeline afterwards.
Described air intake installation comprises air inlet seat, seal cover and air filtration diaphragm, air inlet seat inside is arranged on ending on the liquid defecator or connect on the conduit with only liquid defecator and flow regulator on the dropping funnel, be provided with air inlet at the air inlet seat outer wall, seal cover arranges the air inlet place and air inlet can be sealed, described air inlet is by the channel connection of air inlet and air inlet seat inside, in the described air filtration diaphragm arrangement air inlet.
Described seal cover one end is hinged on the air inlet seat, and seal cover is provided with capping, and capping can be placed in the air inlet and seal.
This utility model is to have adopted after only the liquid transfusion device ends liquid, end the liquid filter pipeline at the transfusion device of inactive liquid section the air intake installation that air enters is set, increased pressure, make the liquid smooth delivery of power finish, be provided with the air filtration film in the air intake installation simultaneously, 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 structural representation of the present utility model.Fig. 2 is this utility model partial structurtes sketch maps.
The specific embodiment
Shown in Fig. 1,2, a kind of noresidue fluid dispenser, comprise transfusion device pipeline 1, on the described transfusion device pipeline successively with perforator 2, dropping funnel 3, end liquid defecator 4, flow regulator 5 and transfusion needle 6 and be communicated with, described ending between liquid defecator and the flow regulator is provided with air intake installation, and air intake installation only can directly be connected with liquid filter or be arranged on the liquid filter transfusion device pipeline afterwards.
Described air intake installation comprises air inlet seat 70, seal cover 71 and air filtration diaphragm 72, air inlet seat 70 inside arrange and are communicated with the passage 75 that ends liquid defecator 4 and flow regulator 5, be provided with air inlet 76 at air inlet seat 70 outer walls, seal cover 71 is hinged on the air inlet seat 70, seal cover 71 is provided with capping 73, capping 73 can be placed in can be with air inlet 76 sealings in the air inlet 76, described air inlet 76 is communicated with the passage 75 of air inlet seat 70 inside by air inlet 74, and described air filtration diaphragm 72 arranges in the air inlet 75.
Operation principle of the present utility model is: when medicinal liquid was in static shape in ending the liquid transfusion device, at this moment, venous pressure, medicinal liquid gravity, atmospheric pressure all were in balanced shape, make medicinal liquid be delivered to vein under the atmospheric pressure effect; After only the liquid transfusion device ends liquid, pipeline arranges the air intake installation 7 that air enters after the transfusion device of inactive liquid section ends liquid filter 4, increased pressure, make the liquid smooth delivery of power finish, be provided with air filtration film 40 in the air intake installation simultaneously, prevent the medicinal liquid water clock, after ending liquid, in time open air intake installation 7 seal covers 71, can finish the conveying of residual liquor, if can not in time open, produce the blood back phenomenon, by opening seal cover 71, 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.Above-described embodiment is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, and 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.
