Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of intravenous transfusion device.
Background technology
Transfusion device is a kind of conventional medical apparatus and instruments, for setting up passage between vein and medicinal liquid, realizes intravenous drip administration.Common disposable transfusion device does not have automatic liquid-stopping function, easily blood back phenomenon occurs, needs patient or nursing staff to observe infusion process situation in time, and nurse's labor intensity is large, and easily causes family members and patient's fear.The transfusion device in prior art with automatic liquid-stopping function is many does not have Anti-bubble function, only there is minority precision filter infusion set to have automatic liquid-stopping and Anti-bubble function simultaneously, but, this precision filter infusion set complex structure, production cost is higher, adds the financial burden of patient.
Utility model content
The technical problem that utility model will solve is: provide a kind of transfusion device with automatic liquid-stopping and Anti-bubble function, this transfusion device not only can anti-return blood, can also prevent bubble from entering long duct, be convenient to transfusion nursing, reduce nurse's labor intensity, it is simple that this transfusion device has structure, and production cost is low, the advantage of use safety.
The technical scheme that technical solution problem is taked: a kind of transfusion device with automatic liquid-stopping and Anti-bubble function, comprise bottle plug puncture unit, air filter, conduit, dropper component, long duct, flow regulator, liquid medicine filter, intravenous needle, described dropper component comprises by dropping funnel upper cover, the housing that dropping funnel cylindrical shell and dropping funnel lower cover are formed, dropping funnel covers the feed tube be provided with conduit grafting, the drain pipe be provided with long duct grafting is covered under dropping funnel, float position-limited rack is fixed with in the periphery of the dropping funnel lower cover fluid mouth of pipe, the float that can float or sink is provided with in float position-limited rack, fluid mouth of pipe sealed Cellophane is provided with in the bottom of float, bubble forcible entry device is also provided with in the fluid mouth of pipe, described bubble forcible entry device is the broken bubble dividing plate longitudinally arranged in the fluid mouth of pipe.
As improvement of the present utility model: broken bubble dividing plate is cross broken bubble dividing plate.
As further improvement of the utility model: the thickness of broken bubble dividing plate is 0.1-1mm.
Broken bubble dividing plate upper limb is lower than fluid orifice plane 3-8mm.
Improve as a step more of the present utility model: broken bubble dividing plate upper limb is lower than fluid orifice plane 5mm.
Improve as another kind of the present utility model: dropping funnel cylindrical shell has Quick air-discharge hole, in Quick air-discharge hole, efficiently block water film and seal rubber plug are housed.
As another improvement of the present utility model: cover the syringe being also provided with and communicating with dropping funnel inner chamber on dropping funnel, be provided with sealed gum cap at the injection mouth of pipe.
Beneficial effect: the transfusion device with automatic liquid-stopping and Anti-bubble function of the present utility model, bottle plug puncture unit is comprised owing to have employed described transfusion device, air filter, conduit, dropper component, long duct, flow regulator, liquid medicine filter, intravenous needle, described dropper component comprises by dropping funnel upper cover, the housing that dropping funnel cylindrical shell and dropping funnel lower cover are formed, dropping funnel covers the feed tube be provided with conduit grafting, the drain pipe be provided with long duct grafting is covered under dropping funnel, float position-limited rack is fixed with in the periphery of the dropping funnel lower cover fluid mouth of pipe, the float that can float or sink is provided with in float position-limited rack, fluid mouth of pipe sealed Cellophane is provided with in the bottom of float, bubble forcible entry device is also provided with in the fluid mouth of pipe, described bubble forcible entry device is the technical scheme of the broken bubble dividing plate longitudinally arranged in the fluid mouth of pipe, float upwards floats by medicinal liquid during normal infusion in dropping funnel, the fluid mouth of pipe is in open state, medicinal liquid enters long duct through drain pipe, when the bubble entering drain pipe with medicinal liquid runs into brokenly bubble dividing plate, bubbles burst the emersion fluid mouth of pipe, can prevent bubble from entering long duct, at the end of transfusion is tending towards, medicinal liquid in dropping funnel reduces, float sinks, the sealed Cellophane of float bottom is by fluid ferrule, medicinal liquid residual in dropping funnel can seal the fine gap between sealed Cellophane and the fluid mouth of pipe further, thus reach the airtight fluid mouth of pipe, automatic liquid-stopping, the object of blood return prevention, therefore, the transfusion device with automatic liquid-stopping and Anti-bubble function of the present utility model not only can anti-return blood, can also prevent bubble from entering long duct, be convenient to transfusion nursing, reduce nurse's labor intensity, it is simple that this transfusion device has structure, production cost is low, the advantage of use safety.In addition, the transfusion device with automatic liquid-stopping and Anti-bubble function of the present utility model also overcomes in prior art the defect adopting the transfusion device arranging anti-foam crack structure on fluid tube wall cannot utilize float automatic liquid-stopping, achieve integrate anti-foam, automatic liquid-stopping function.Due to have employed brokenly bubble dividing plate be cross break bubble dividing plate technical characteristic, anti-foam better effects if, uses safer.Owing to reasonably defining brokenly the thickness of bubble dividing plate, while reaching orcible entry bubble effect, reduce broken bubble dividing plate to the resistance of medicinal liquid, reduce broken bubble dividing plate to the impact of normal infusion.Owing to reasonably defining brokenly the distance of bubble dividing plate upper limb and fluid orifice plane, prevent brokenly bubble dividing plate interference sealed Cellophane and fluid ferrule, and be conducive to the quick emersion drain pipe of bubble after tearing down, reduce bubble to the impact of transfusion speed.Quick air-discharge hole is had owing to have employed on dropping funnel cylindrical shell, the technical characteristic of efficiently block water film and seal rubber plug is housed in Quick air-discharge hole, by opening encapsulation plug can realize medicinal liquid quick, still enter dropping funnel, not only shorten transfusion time, and reduce in pipeline the probability forming bubble.Owing to have employed the syringe covering on dropping funnel and be also provided with and communicate with dropping funnel inner chamber, be provided with the technical characteristic of sealed gum cap at the injection mouth of pipe, facilitate the operation adding other medicament in the process of transfusion in medicinal liquid.
