Abstract
The invention belongs to the field of medical appliances, and in particular relates to an automatic liquid-stopping and automatic exhaust infusion device. The infusion device comprises a dropping funnel, and is characterized in that a floating body is arranged in the dropping funnel; a sealing film capable of moving freely is arranged inside the floating body; the sealing film is communicated with the outside through an opening at the bottom of the floating body; the dropping funnel is formed by combination of an upper cover, a dropping funnel body and a hard base; an exhaust hole communicated with the inner cavity of the dropping funnel and the outside atmosphere are formed on the base; and an exhaust part is arranged at the end of the inner cavity of the dropping funnel of the exhaust hole. The automatic liquid-stopping and automatic exhaust infusion device is of a simple and reasonable structure, the base, the floating body and the sealing film together form an automatic liquid-stopping structure, and automatic liquid stopping is realized after liquid medicine is infused; and the exhaust hole and the exhaust part on the base together form an automatic exhaust structure, gas can be exhausted automatically in the infusion process, and bubbles are prevented from being carried into an infusion catheter. The automatic liquid-stopping and automatic exhaust infusion device is safe and convenient in using, and facilitates treatment to clinical patients.
Description
Technical field
The present invention relates to a kind of 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 simple in structure, easy to use and safe and reliable automatic liquid-stopping automatic-exhaust transfusion device is provided.
The technical solution adopted for the present invention to solve the technical problems is: described automatic liquid-stopping automatic-exhaust transfusion device, comprise dropping funnel, be provided with buoyancy aid in the dropping funnel, the inside of buoyancy aid is provided with the sealed film that can move freely, sealed film communicates with the external world by the opening of buoyancy aid bottom, dropping funnel is combined by loam cake, dropping funnel body and hard base, and the steam vent that is communicated with dropping funnel inner chamber and ambient atmosphere is set on the base, and the dropping funnel inner chamber end of steam vent is provided with exhaust part.
In the dropping funnel of this transfusion device, buoyancy aid bottom by rivet welding with the sealed film fixed position in buoyancy aid, base, buoyancy aid, sealed film consist of the automatic liquid-stopping structure jointly, behind the medicinal liquid infusion-completed, after being whole outflow of medicinal liquid in the dropping funnel, buoyancy aid can fall to the bottom of dropping funnel automatically, and the sealed film of buoyancy aid bottom is realized automatic liquid-stopping with the transfusion catheter sealing that the dropping funnel bottom connects; Steam vent on the base, exhaust part consist of automatic exhausting equipment jointly, prevent from bubble is brought in the transfusion catheter.
Wherein:
Described base upper end rivet welding limited block prevents that the excessive height of buoyancy aid come-up from stopping up the inlet of dropping funnel.
Described exhaust part is the hydrophobic air filter membrane, and exhaust part is welded on the base.
The invention has the beneficial effects as follows:
This automatic liquid-stopping automatic-exhaust transfusion device is simple and reasonable, and base, buoyancy aid, sealed film consist of the automatic liquid-stopping structure jointly, 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.
