Description
Technical field
This utility model relates to a kind of medical intravenous infusion set, particularly a kind of can self-bleeding intravenous transfusion device, belong to medical instruments field.
Background technology
At present, the general infusion set that medical field is commonly used constitutes by parts such as bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion upper conduit, exhaust manifolds, air filter, last dropper, dropping funnel, flow regulator, transfusion downcomer, liquid medicine filter and disposable use venoclysis needles.When general infusion set has just begun in transfusion, medicinal liquid flows out from dropper by pipeline, enter dropping funnel, liquid is easily discharged the gas in the dropping funnel downwards the formation gas-liquid mixture and is entered down in the transfusion catheter, therefore produces bubble, simultaneously, because of the surface tension effects of transfusion catheter inwall, the inwall of transfusion catheter is a spot of bubble of absorption easily, and it is comparatively difficult, time-consuming and loaded down with trivial details to get rid of consequent bubble process, if the bubble that is produced enters in patient's body, easily cause harm such as aeroembolism.So, medical personnel are before infusing, must be artificial with the emptying as much as possible of the bubble in the catheter of transfusion system, common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper, earlier dropping funnel is hung upside down, squeeze dropping funnel with hands simultaneously, medicinal liquid is entered in the dropping funnel, treat that certain amount of fluid is full of dropping funnel after, just most bubble may be got rid of, the process of this artificial aerofluxus bubble is not only loaded down with trivial details but also time-consuming, is unfavorable for promptly infusing and giving emergency treatment to a patient.At the problems referred to above, Chinese patent CN101337098A and CN101708349A disclose respectively a kind of can self-bleeding intravenous transfusion device, both cover setting at dropping funnel can stretch into exhaustor in the dropping funnel or exhaust needle and combine with the air filtration film of the not discharge opeing of aerofluxus of device on exhaustor or exhaust needle opening and realize the automatic vent of dropping funnel, exempt the operating process that loaded down with trivial details time-consuming again artificial aerofluxus is steeped, but these two patent applications are owing to be to cover exhaustor or the exhaust needle that setting can be stretched into the dropping funnel inner chamber at dropping funnel all, because exhaustor or exhaust needle aperture are little, be subjected to the capillary effect of liquid in the dropping funnel can be stained with water droplet and stop up the mouth of pipe or pinhole aperture, influence is automatic vent for the second time, and the exhaustor that stretches in the dropping funnel is two kinds of different materials with dropping funnel, can influence the observation drip velocity like this, simultaneously, because the ring stand of fixing permeable air-locked permeable filter membrane directly is installed in the dropping funnel from the opening of dropping funnel top, ring stand is difficult to accurate location, there is the phenomenon of inclination easily, thereby cause production efficiency low, be easy to generate substandard products, the cost height, and the ring stand of fixing permeable air-locked permeable filter membrane is two kinds of different materials with dropping funnel, its coefficient of expansion is different, the space occurs between dropping funnel inwall and the ring stand, thereby influence the sealing between permeable air-locked permeable filter membrane ring stand and the dropping funnel.
