Abstract
The utility model discloses a burette filter of a transfusion apparatus. A burette is combined by an upper cover and a filtering base, the filtering base is arranged at the lower part of the upper cover, a liquid outlet channel is arranged at the lower part of the filtering base, a groove matched with the side wall of the upper cover is arranged on the side wall of the filtering base, and the side wall of the upper cover is inserted into the groove and glued with the groove hermetically; and a filter membrane is arranged in the filtering base, and a fixed compression ring is arranged on the filter membrane. In the burette filter, as the upper cover is matched and glued with the groove of the filtering base hermetically, the processing is simple and the sealing effect is good. The fixed compression ring is adopted to fix the filter membrane and the fixed compression ring is connected with the filtering base hermetically, so as to prevent lateral leakage of the filter membrane. The micro-pore filter membrane can effectively prevent the passing of air dissolving in liquid medicine and prevent air from entering a human body during transfusion, so as to achieve the purpose of safe transfusion.
Description
Technical field
This utility model relates to the medical apparatus and instruments that clinical transfusion is used, and especially relates to a kind of dropping funnel filter of transfusion device.
Background technology
The transfusion device of clinical use is made up of bottle plug puncture unit and protective sleeve, exhaust apparatus, transfusion upper conduit, dropping funnel, dropper, liquid medicine filter, infusion pipeline, flow regulator and injection member.The medicine filter is located in the dropping funnel, forms by filter membrane being fixed on the dropping funnel bottom usually.The filter membrane of the filter of this mode is easy to because after the fixing absent-mindedness, liquid passes through from the side, thereby fails to filter fully.
Publication number is that the application for a patent for invention of CN101791444A discloses a kind of safe bubble-free infusion set, employing covers the installation gas deflation assembly at dropping funnel, in the dropping funnel bottom safe bubble-free assembly is installed, the safe bubble-free assembly is made up of common liquid medicine filtering membrane, precision liquid medicine filter membrane and medical filtration base, common liquid medicine filtering membrane, precision liquid medicine filter membrane are fixed in the medical filtration base, and wherein common liquid medicine filtering membrane is positioned at precision liquid medicine filter membrane upper strata.Safe bubble-free assembly in this technical scheme is that filter exists the sealing difficulty, the problem of easy side leakage, and same processing assembling is also relatively more difficult.
Summary of the invention
This utility model provides the infusion unit titrimeter filter of a kind of easy to process, secondary filter, side leakage free.
A kind of dropping funnel filter of transfusion device, be combined to form dropping funnel by loam cake, filtration base, described loam cake bottom is provided with the filtration base, and described filtration base bottom is provided with liquid outlet channel, sidewall is provided with the groove that cooperates with the sidewall of loam cake, and the sidewall of loam cake inserts in the groove and seals bonding; Be provided with filter membrane in the described filtration base, be provided with fixed pressure ring above the filter membrane.
Described fixed pressure ring is connected with the inner seal that filters base, can guarantee that like this filter membrane side leakage can not take place.
Described fixed pressure ring is provided with reinforcement.
Described filter membrane is a microporous filter membrane, and behind dropping funnel giving drugs into nose liquid stream sky, liquid level can rest on the moistening filter membrane automatically, and air can not see through moistening filter membrane face, prevents in the air admission human body.
This utility model by loam cake with filter cooperating and sealing bonding formation dropping funnel of base groove, processing is simple, and good sealing effect.Adopt fixedly filter membrane of fixed pressure ring, fixed pressure ring is connected and sealed with filtering base, guarantees that filter membrane side leakage can not take place.Adopt microporous filter membrane, can stop the air that is dissolved in medicinal liquid to pass through effectively, can prevent that bubble enters human body in the infusion process, reaches purpose of safety.
