Description
Technical field
The present invention relates to a kind of exhaust transfusion device, belong to medical instruments field.
Background technology
Transfusion is widely used Therapeutic Method in clinical treatment, and safety is the indispensable essential condition of transfusion.
When general infusion set herb liquid starts to enter dropping funnel, very easily form the mixture of gas and liquid, this gas-liquid mixture can enter rapidly in the infusion pipeline below dropping funnel, form bubble phenomenon during transfusion, the healthy of patient is threatened, so medical personnel are when infusing, infuse again after the bubble in transfusion catheter must being discharged completely.The method of usual employing is, after bottle plug puncture unit is thrust transfusion bottle stopper, be inverted or extruding dropping funnel, make medicinal liquid enter in dropping funnel, when rapid again after the liquid about being filled with half in dropping funnel, dropping funnel is returned to normal operating condition, nonetheless, tube wall below dropping funnel also often adsorbs bubble, also need medical personnel to pinch bubble with finger bullet, this kind of operational approach is comparatively loaded down with trivial details, brings great inconvenience to medical personnel.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of structure simple, the air in dropping funnel can be discharged smoothly, the easy to use and exhaust transfusion device of safety.
Exhaust transfusion device of the present invention, comprise dropping funnel, in dropping funnel, exhaust apparatus is set, exhaust apparatus comprises and to be arranged on bottom dropping funnel and to be communicated with the exhaustor of dropping funnel inner chamber and ambient atmosphere and hydrophobic air filtration media, air filtration media to be fixed on end face that exhaustor is positioned at dropping funnel intracavity and suitable with the above-mentioned end face of exhaustor, and the upper surface of air filtration media is along the convex cambered surface to cavity direction in dropping funnel of exhaustor axial direction.
Wherein, the end face that exhaustor is positioned at dropping funnel inner chamber can be one along the convex cambered surface to dropping funnel inner chamber of exhaustor axial direction or the cambered surface reverse with above-mentioned cambered surface, also can be a plane vertical with dropping funnel axial direction; The fixed form of air filtration media and exhaustor end face for welding, riveting, bonding or fixed by securing member; Air filtration media is hydrophobic material.
In this transfusion device, exhaustor and air filtration media, after dropping funnel inner chamber is combined, define one along the convex cambered surface to dropping funnel inner chamber of exhaustor axial direction.When after puncture, medicinal liquid enters dropping funnel, air in dropping funnel is discharged in ambient atmosphere through air filtration media and exhaustor, when the amount of liquid medicine in dropping funnel increases to after liquid level floods air filtration media, because of the hydrophobic interaction of air filtration media, medicinal liquid cannot continue to discharge through herein, so far medicinal liquid stops entering dropping funnel, keeps liquid level constant, completes dropping funnel medicinal liquid and fills.
When dropping funnel fills medicinal liquid, the surface being positioned at dropping funnel inner chamber because of air filtration media is cambered surface, in relatively narrow dropping funnel space, uses the larger leaving area of less spatial placement, improves exhaust efficiency; During transfusion, when continuing to flow into dropping funnel without medicinal liquid, liquid level progressively declines, and the surface contacted with medicinal liquid due to air filtration media is cambered surface, and medicinal liquid cannot stop under gravity, ensure that the unimpeded of exhaust apparatus, makes its degassing function continuously effective.
The beneficial effect that the present invention is compared with prior art had is:
This transfusion system structure advantages of simple, during use without the need to be inverted or extruding dropping funnel, easy to operate, the air in dropping funnel can be discharged by air filtration media and exhaustor smoothly, and keep transfusion time dropping funnel in liquid level, safe and convenient to use, fast reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of exhaust apparatus in dropping funnel.
In figure: 1, bottle plug puncture unit; 2, infusion pipeline; 3, dropping funnel; 4, air filtration media; 5, exhaustor; 6, flow regulator; 7, liquid medicine filter; 8, cone joint; 9, venoclysis needle.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
As Fig. 1, shown in 2, this exhaust transfusion device comprises bottle plug puncture unit 1, infusion pipeline 2, dropping funnel 3, flow regulator 6, liquid medicine filter 7, cone joint 8 and venoclysis needle 9 (also can not be with venoclysis needle), in dropping funnel 3, exhaust apparatus is set, exhaust apparatus comprises and to be arranged on bottom dropping funnel 3 and to be communicated with the exhaustor 5 of dropping funnel 3 inner chamber and ambient atmosphere and hydrophobic air filtration media 4, exhaustor 5 is connected with dropping funnel 3 one, air filtration media 4 to be fixed on end face that exhaustor 5 is positioned at dropping funnel 3 intracavity and suitable with the above-mentioned end face of exhaustor 5, after the two is relatively fixing, the upper surface of air filtration media 4 forms one along the convex cambered surface to cavity direction in dropping funnel 3 of exhaustor 5 axial direction.
Wherein, for reaching the said structure of exhaust apparatus, the end face that exhaustor 5 is positioned at dropping funnel 3 inner chamber can be one along the convex cambered surface to dropping funnel 3 inner chamber of exhaustor 5 axial direction (namely the present embodiment adopts this version) or the cambered surface reverse with above-mentioned cambered surface, also can be a plane vertical with dropping funnel 3 axial direction; The fixed form of air filtration media 4 and exhaustor 5 end face for welding, riveting, bonding or fixed by securing member; Air filtration media 4 is the hydrophobic material that can form arc shape.
Operation principle and process:
When after puncture, medicinal liquid enters dropping funnel 3, air in dropping funnel 3 is discharged in ambient atmosphere through air filtration media 4 and exhaustor 5, when the amount of liquid medicine in dropping funnel 3 increases to after liquid level floods air filtration media 4, because of the hydrophobic interaction of air filtration media 4, medicinal liquid cannot continue to discharge through herein, so far medicinal liquid stops entering dropping funnel 3, keeps liquid level constant, completes dropping funnel 3 medicinal liquid and fills.
When dropping funnel 3 fills medicinal liquid, the surface being positioned at dropping funnel 3 inner chamber because of air filtration media 4 is cambered surface, in relatively narrow dropping funnel 3 space, uses the larger leaving area of less spatial placement, improves exhaust efficiency; During transfusion, when continuing to flow into dropping funnel 3 without medicinal liquid, liquid level progressively declines, and the surface contacted with medicinal liquid due to air filtration media 4 is cambered surface, and medicinal liquid cannot stop under gravity, ensure that the unimpeded of exhaust apparatus, makes its degassing function continuously effective.
