Abstract
The utility model provides an automatic-exhaust-type infusion device which comprises an infusion catheter and an air inflow needle. The front end of the infusion catheter is provided with a bottle cap liquid inflow needle, the rear end of the infusion catheter is provided with a vein infusion needle, the infusion catheter between the bottle cap liquid inflow needle and the vein infusion needle is sequentially provided with a dripping bucket and a flow adjustor, the upper portion of the dripping bucket is provided with a dripping bucket cover, a liquid outlet of the dripping bucket is connected with a liquid guide column with an open upper end, a liquid outlet cavity communicated with the liquid outlet of the dripping bucket is arranged in the liquid guide column, a liquid guide cap is arranged on the liquid guide column, and a liquid guide gap is arranged between the liquid guide cap and the outer wall of the liquid guide column. By means of a capillary principle, liquid is sucked into the liquid guide column through the liquid guide gap between the liquid guide cap and the liquid guide column without limit of liquid medicine, the bubbling problem is effectively solved, meanwhile the bubbling problem caused by the exceedingly quick infusion speed during infusion can be solved, the design is reasonable, the structure is simple, utilization is convenient and the purpose of automatic exhaust can be achieved.
Description
Technical field
This utility model relates to a kind of area of medical devices, particularly a kind of automatic vent type transfusion device.
Background technology
In hospital, venous transfusion has become a kind of general therapeutic modality, and the transfusion device that uses needed the nurse to spend a lot of times to remove to discharge bubble before transfusion at present, because aerofluxus is unclean, had bubble along with medicinal liquid enters human body, damaged to patient.Can well address this problem from the exhaust transfusion device, but existing automatic vent type transfusion device mainly adopts the surface tension principle of liquid to realize, because the capillary concordance of medicinal liquid, so this structure is difficult to satisfy all medicinal liquids, the scope of application is wideless.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, and automatic vent type transfusion device a kind of reasonable in design, easy to use is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of automatic vent type transfusion device, it comprises transfusion catheter and air inlet needle, the transfusion catheter front end is provided with bottle cap feed liquor pin, the transfusion catheter rear end is provided with venoclysis needle, be provided with dropping funnel and flow regulator on the transfusion catheter between bottle cap feed liquor pin and the venoclysis needle successively, be characterized in: be provided with the dropping funnel block on the top of dropping funnel, be connected with the drain post of upper end open at the liquid outlet of dropping funnel, be provided with the fluid chamber that is communicated with the dropping funnel liquid outlet in the drain post, the drain post is provided with the drain block, is provided with the drain slit between drain block and the drain column outer wall.
Technical problem to be solved in the utility model can also further realize that the width in drain slit is 0.1-2mm by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the width in drain slit is 1mm by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the drain block is 0.5-5mm with the distance of drain post upper port by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the drain block is 1mm with the distance of drain post upper port by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the height of drain post is 2-12mm by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the height of drain post is 10mm by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the width in drain slit is 1mm by following technical scheme, and the drain block is 1mm with the distance of drain post upper port, and the height of drain post is 10mm.
Compared with prior art, this utility model utilizes capillary theory, drain slit by between drain block and the drain post is drawn onto liquid in the drain post, thereby can not be subjected to the restriction of medicinal liquid, the problem of effectively solution bubble, can solve simultaneously the too fast air bubble problem that causes of transfusion speed once in a while when transfusion, it is reasonable in design, and is simple in structure, easy to use, can reach self-bleeding purpose.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of air inlet needle.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
See figures.1.and.2, a kind of automatic vent type transfusion device, it comprises transfusion catheter 6 and air inlet needle 9, transfusion catheter 6 front ends are provided with bottle cap feed liquor pin 1, transfusion catheter 6 rear ends are provided with venoclysis needle 8, be provided with dropping funnel 3 and flow regulator 7 on the transfusion catheter 6 between bottle cap feed liquor pin 1 and the venoclysis needle 8 successively, be provided with dropping funnel block 2 on the top of dropping funnel 3, be connected with the drain post 5 of upper end open at the liquid outlet of dropping funnel 3, the height of drain post 5 is 2-12mm, preferred 10mm, be provided with the fluid chamber that is communicated with dropping funnel 3 liquid outlets in the drain post 5, drain post 5 is provided with drain block 4, is provided with the feed liquor slit between the upper port of drain block 4 and drain post 5, and drain block 4 is 0.5-5mm with the distance of drain post 5 upper port, preferred 1mm, be provided with the drain slit between drain block 4 and drain post 5 outer walls, the width in drain slit is 0.1-2mm, preferred 1mm.
Bottle cap feed liquor pin 1 and air inlet needle 9 are inserted in the bottle, liquid at first enters dropping funnel 3 from bottle cap feed liquor pin 1, medicinal liquid in 5 to 10 seconds the time dropping funnel 3 reaches 1/3 to 2/3 place of dropping funnel 3, because capillarity, medicinal liquid can along with drain block a shot 4 and drain post 5 between the drain slit enter the drain post 5 from drain post 5 upper port, medicinal liquid enters transfusion catheter 6 from drain post 5 again, step by step the gas in the transfusion catheter 6 is discharged.This process does not need to push the effect that dropping funnel 3 just can reach aerofluxus smoothly, and its exhaust and convenient is quick.
