摘要:
Disclosed is a disposable needle filter apparatus with a universal truncated syringe-receiving neck to enable the filtration of fluids/solutions aspirated into a needle-bearing syringe. The apparatusincludes a needle seal stopper and needle stop to create a substantially airtight chamber to facilitate fluid aspiration through an enclosed filter and into the syringe. In an alternative embodiment,the filter apparatus includes an extended syringe-receiving neck configured to receive a specifically sized syringe/needle combination. In a further embodiment, the receiving neck is constructed as amodular unit to allow for interchangeable necks to accommodate different needle and syringe sizes with different cross-sectional diameters. In a yet further embodiment, the neck is constructed with stepped tapered segments of serially larger cross-sectional diameters to accommodate differently sized syringes. In a still further embodiment, the apparatus includes an accessory needle secured to theapparatus inlet.
