Abstract
The invention belongs to the field of medical instruments, in particular to a disposable infusion apparatus capable of stopping liquid and exhausting air automatically. The infusion apparatus comprises a dropping funnel, wherein the dropping funnel comprises an upper cover, a dropping funnel body and a base. The infusion apparatus is characterized in that a liquid stopping filtering membrane is arranged in the base; the outer edge of the liquid stopping filtering membrane is welded with the inner wall of the base; the base is hard; an air exhaust hole communicating an inner cavity of the dropping funnel with the external atmosphere is formed in the base wall; and an air exhaust piece is arranged at an dropping funnel inner cavity end of the air exhaust hole. The disposable infusion apparatus capable of stopping liquid and exhausting air automatically is simple and reasonable in structure; the base and the liquid stopping filtering membrane together form an automatic liquid stopping structure, and after infusion, automatic liquid stopping is realized; the air exhaust hole and the air exhaust piece on the base together form an automatic air exhaust structure; air can be exhausted automatically in an infusion process, and bubbles are prevented from being brought to an infusion catheter; the use is safe and convenient; and treatment for a clinical patient is facilitated.
Description
Technical field
The present invention relates to a kind of disposable automatic liquid-stopping automatic-exhaust transfusion device, belong to the medical instruments field.
Background technology
At present, when hospital carries out venous transfusion or blood transfusion to clinical patients, generally use disposable transfusion device, like this, played useful effect to preventing the cross infection between the patient.Yet, use this disposable transfusion device also to exist weak point, be that current disposable transfusion device is behind the medicinal liquid infusion-completed, because there not being the automatic-diversion closure function, to in time change medicinal liquid bottle (bag) or pull out transfusion needle, can bring unsafe factor to the patient otherwise air will enter transfusion catheter, be unfavorable for the treatment of clinical patients; In addition, when the transfusion device herb liquid begins to enter dropping funnel, very easily form the mixture of gas and liquid, this gas-liquid mixture can enter rapidly in the infusion pipeline of dropping funnel below, bubble phenomenon when forming transfusion, the healthy of patient threatened, so medical personnel infuse after the bubble in the transfusion catheter must being discharged fully when transfusion again.Usually the method that adopts is, after bottle plug puncture unit is thrust transfusion bottle stopper, be inverted or the extruding dropping funnel, medicinal liquid is entered in the dropping funnel, behind the liquid that is filled with in the dropping funnel about half, rapidly dropping funnel is returned to normal operating condition again, nonetheless, also often adsorb bubble on the tube wall, also need medical personnel to pinch bubble with the finger bullet, this kind 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: a kind of rational in infrastructure, simple and efficient to handle and safe and reliable disposable automatic liquid-stopping automatic-exhaust transfusion device is provided.
Disposable automatic liquid-stopping automatic-exhaust transfusion device of the present invention, comprise dropping funnel, dropping funnel is formed by loam cake, dropping funnel body and base combination, arrange in the base and end the liquid filter membrane, end outward flange and the base inner wall welding of liquid filter membrane, base adopts hard base, and the steam vent that is communicated with dropping funnel inner chamber and ambient atmosphere is set on the base wall, and the dropping funnel inner chamber end of steam vent is provided with exhaust part.
Wherein, exhaust part is the hydrophobic air filter membrane, and exhaust part is welded on the base.
In the dropping funnel of this transfusion device, end the liquid filter membrane by being welded and fixed the position in base, hard base, end the liquid filter membrane and jointly consist of the automatic liquid-stopping structure; Base wall is provided with steam vent, and exhaust part is welded on the base, jointly consists of automatic exhausting equipment by exhaust part and steam vent, prevents from bubble is brought in the transfusion catheter.
End to intercept air after the liquid filter membrane infiltrates and pass through, play the automatic liquid-stopping function, thereby needn't worry that liquid walks sky.When many bottle liquid medicines of infusion, even in time do not change second bottle after the first bottle liquid medicine infused, can separate air force liquid to stop to flow owing to ending the liquid filter membrane when liquid flows in the filter, avoid medicinal liquid to continue to walk sky, thereby avoided the patient blood back phenomenon to occur.And after changing new bottle since the steam vent on the hard base wall from degassing function, the air that upstream can be got off is discharged automatically, thereby can make the dropping funnel automatic liquid feeding and need not manually-operated, thus assurance can continue normal infusion.
The beneficial effect that the present invention compared with prior art has is:
This disposable automatic liquid-stopping automatic-exhaust transfusion device is simple and reasonable, base, ends the liquid filter membrane and jointly consists of the automatic liquid-stopping structure, realizes automatic liquid-stopping behind the medicinal liquid infusion-completed; Steam vent on the base, exhaust part consist of automatic exhausting equipment jointly, can automatic vent in the infusion process, prevent from bubble is brought in the transfusion catheter, and safe and convenient to use, be conducive to the treatment to clinical patients.
