Abstract
The invention discloses an automatic exhaust liquid-stopping drip chamber relating to the field of medical infusion instruments. The automatic exhaust liquid-stopping drip chamber comprises a drip chamber body, a ventilation waterproof film, a water-permeable air-proof film and a lower sealing cover, wherein the lower end of the side wall of the drip chamber body extends downwards to be connected with the upper part of the lower sealing cover so as to form an exhaust liquid-stopping chamber; a liquid discharge tube is arranged at the lower end of the lower sealing cover; exhaust ports are formed in the upper part of the extensional section at the lower end of the drip chamber body; the ventilation waterproof film is arranged at the upper part of the exhaust liquid-stopping chamber; the water-permeable air-proof film is arranged at the lower part of the exhaust liquid-stopping chamber; the lower part of a liquid guide tube of the drip chamber body extends into a chamber between the ventilation waterproof film and the water-permeable air-proof film; and the exhaust ports of the extensional section of the drip chamber body is formed in the ventilation waterproof film. The automatic exhaust liquid-stopping drip chamber is simple in structure and convenient to use, can effectively separate the air from the liquid in the infusion process, and simultaneously prevent the phenomenon of blood return when the infusion is accomplished.
Description
Technical field
The present invention relates to medical infusion utensil field, be specially a kind of automatic vent and stop the drop bucket.
Background technology
The major function of dropping funnel of the prior art is the filled situation of observing drop and liquid, function singleness, easily be entrained with air in infusion pipeline, thereby increased medical personnel's working strength, after transfusion finishes simultaneously, if can not in time depress actuator and pull out syringe needle, can produce the blood back phenomenon, the serious security incident that air enters human body may occur in serious.
Summary of the invention
The purpose of this invention is to provide a kind of automatic vent and stop the drop bucket, overcome problems of the prior art, easy to use, safe and reliable.、
The technical scheme that realizes above-mentioned purpose is: automatic vent stops the drop bucket, it is characterized in that: comprise dropping funnel body, ventilative block water film, permeable gas barrier film and lower sealing cover, the upper end of dropping funnel body is provided with feed tube, the lower end of dropping funnel body is provided with catheter, the side wall lower ends of dropping funnel body is connected to form aerofluxus to the top of downward-extension and described lower sealing cover and stops sap cavity, the lower end of lower sealing cover is provided with discharging tube, and the top of the extension of dropping funnel body lower end is provided with air vent; The described ventilative film that blocks water is arranged on the top that aerofluxus stops sap cavity, described permeable gas barrier film is arranged on the bottom that aerofluxus stops sap cavity, the catheter bottom of described dropping funnel body extends in the ventilative cavity that blocks water between film and permeable gas barrier film, and the air vent of described dropping funnel body extension is arranged on the top of film of blocking water of breathing freely.
Work process of the present invention:
Medicinal liquid is after feed tube enters dropping funnel, flow on permeable gas barrier film by catheter, medicinal liquid sees through permeable gas barrier film and is flowed out by the leakage fluid dram of lower sealing cover, by permeable gas barrier film with water, edema caused by disorder of QI from, stop gas to enter leakage fluid dram, there is no all the time air in the medicinal liquid that discharging tube is flowed out.The air that simultaneously aerofluxus stops sap cavity discharges through the air vent that the ventilative film that blocks water enters the top of extension, dropping funnel lower end, thereby has realized under watertight prerequisite automatically air-out effectively.When transfusion finishes, in the situation that there is no gravity, because the function of permeable gas barrier film has stoped entering of air, liquor residue partly is sealed under permeable gas barrier film, realize automatically stopping of transfusion.
The present invention is simple in structure, and is easy to use, can effectively the gas in infusion process, liquid be separated, and avoids simultaneously the blood back phenomenon occurring after the transfusion end.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention mainly is comprised of dropping funnel body 1, ventilative block water film 2, permeable gas barrier film 3 and lower sealing cover 4.
The upper end of dropping funnel body 1 is provided with feed tube 5, the lower end of dropping funnel body 1 is provided with catheter 6, the side wall lower ends of dropping funnel body 1 is connected to form aerofluxus to the top of downward-extension and described lower sealing cover 4 and stops sap cavity 9, the lower end of lower sealing cover 4 is provided with discharging tube 7, and the top of the extension of dropping funnel body 1 lower end is provided with air vent 8.
The ventilative film 2 that blocks water is arranged on the top that aerofluxus stops sap cavity 9, described permeable gas barrier film 3 is arranged on the bottom that aerofluxus stops sap cavity 9, catheter 6 bottoms of described dropping funnel body 1 extend in the ventilative cavity that blocks water between film 2 and permeable gas barrier film 3, and the air vent 8 of described dropping funnel body 1 extension is arranged on the top of film 2 of blocking water of breathing freely.
