Description

One is made up a prescription with priming device of bleeding
Technical field
This utility model relates to a kind of technical field of medical equipment, particularly one and makes up a prescription with priming device of bleeding.
Background technology
Existing liquid medicine dispensation mode, major part is the medicinal liquid adopting syringe suction to need configuration, as the medicinal liquid in ampoule bottle, then syringe is inserted medicated bag or the medicine bottle of sealing, is propelled by the medicinal liquid in syringe into medicated bag or medicine bottle, finally complete whole making up a prescription.In order to raise the efficiency, also have the mode adopting funnel fluid injection, efficiency is higher, specifically by funnel connection container (as transfusion bag or infusion bottle), medicinal liquid is poured over funnel, is injected in container by funnel.
Although existing funnel has liquid-through hole and passage, medicinal liquid injects in container by filler neck, and medicinal liquid is when flowing in container, and container inner liquid medicine naturally injects under gravity and atmospheric pressure operation of nature, is discharged by gas in container by passage simultaneously.Because filler neck size limit, the size of passage is also less, the gas in container velocity of discharge and efficiency comparison low, the speed causing medicinal liquid naturally to be injected in container by filler neck is slow, needing the occasion of large medicine amount liquid configuration, can not meet the demands far away.
Utility model content
Goal of the invention of the present utility model is: when adopting medicinal liquid to make up a prescription by completing in funnel injection container for existing method, air in container is under atmospheric pressure operation of nature power, slower by filler neck passage Natural excrement speed, have impact on the problems referred to above that medicinal liquid injects volumetric efficiency, one is provided to make up a prescription with priming device of bleeding, this priming device of bleeding is communicated with the passage on funnel by air pump, initiatively suction causes tainer air to form negative pressure, and then by the medicinal liquid quick adsorption in funnel in container, medicinal liquid injection efficiency can be substantially increased.
To achieve these goals, the technical solution adopted in the utility model is:
One is made up a prescription with priming device of bleeding, and comprises funnel, and described funnel comprises infundibular body and filler neck, is provided with liquid-through hole and passage in described filler neck, described passage connectivity trachea and air pump.
This makes up a prescription with priming device of bleeding, air pump is communicated with by the passage on filler neck, container is inserted at funnel, medicinal liquid is when injecting in container, air pump is suction initiatively, causes the air in container to form negative pressure, and then can by the medicinal liquid quick adsorption in funnel in container, compare existing funnel by fluid injection mode under gravity and atmospheric operation of nature, the injection efficiency of medicinal liquid can be substantially increased.
Preferably, the outlet of described liquid-through hole and the entrance of passage are oppositely arranged on the sidewall of described filler neck respectively.
Be oppositely arranged on the liquid-through hole on filler neck sidewall and passage, when avoiding medicinal liquid to be flowed out by liquid-through hole, taken away a part of medicinal liquid by the gas flowing into passage and cause waste or blocking passage.
Preferably, the outlet of described liquid-through hole is positioned at the tip, lower end of described filler neck, and the entrance of described passage is positioned at described filler neck side.
The outlet of liquid-through hole be arranged on the tip of filler neck bottom, the entrance of passage is positioned at filler neck side, be equally also in order to by liquid-through hole and passage spaced away from, when avoiding passage to bleed, medicinal liquid is pumped into trachea.
Preferably, described filler neck is provided with the limiting plate limiting described filler neck insertion depth.
Limiting plate, for limiting degree of depth during filler neck insertion container, avoids filler neck to insert container too dark, and medicinal liquid is by funnel after injection container, and when liquid level rising exceeds passage, medicinal liquid is entered in trachea by suck-back when bleeding.
Preferably, described funnel and trachea are formed in one structure.
Funnel and trachea one-body molded, reduce installation time, improve medicinal liquid injection efficiency.
Preferably, described trachea be provided with gas can only from the external world to the check valve that air pump flows into.
Gas can be limited by check valve and can only flow into air pump from passage, after avoiding medicinal liquid to enter trachea, flow into air pump again, damage air pump.
Preferably, described funnel, trachea and check valve are formed in one structure.
Funnel, trachea and check valve are integrated formed structure, in use, only need funnel to insert container, trachea access air pump, and this priming device of bleeding can use, convenience quick for installation; This device can select the plastics extrusion moulding such as polyethylene, easy to process, cost is lower.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, one described in the utility model is made up a prescription with priming device of bleeding, air pump is communicated with by the passage on filler neck, container is inserted at funnel, medicinal liquid is when injecting in container, air pump is suction initiatively, causes the air in container to form negative pressure, and then can by the medicinal liquid quick adsorption in funnel in container, compare existing funnel by fluid injection mode under gravity and atmospheric operation of nature, the injection efficiency of medicinal liquid can be substantially increased;
2, one described in the utility model is made up a prescription with priming device of bleeding, and liquid-through hole and passage is oppositely arranged on filler neck sidewall, when avoiding medicinal liquid to be flowed out by liquid-through hole, is taken away a part of medicinal liquid cause waste or blocking passage by the gas flowing into passage;
3, one described in the utility model is made up a prescription with priming device of bleeding, filler neck is provided with the limiting plate limiting described filler neck insertion depth, limiting plate is for limiting degree of depth during filler neck insertion container, filler neck is avoided to insert container too dark, medicinal liquid by funnel injection container after, when liquid level rising exceeds passage, medicinal liquid is entered in trachea when bleeding by suck-back;
4, one described in the utility model is made up a prescription with priming device of bleeding, and funnel, trachea and check valve adopt integrated formed structure, in use, only needs funnel to insert container, trachea access air pump, and this priming device of bleeding can use, convenience quick for installation; This device can select the plastics extrusion moulding such as polyethylene, easy to process, cost is lower.
