Abstract
An assembly for the removal and examination of amnioytes in early pregnancy by filtering the amniotic fluid and returning the fluid to the fetus subsequent to filtering wherein a conduit structure has a filter incorporated therein and is constructed to include two different paths of fluid flow, one for drawing off said amniotic fluid through the filter means and one for returning the amniotic fluid subsequent to filtering along a path which bypasses said filter structure.
Claims14
A filtering assembly for removing amniocytes from amniotic fluid during pregnancy, said assembly comprising:
- (a) a conduit structure including a first conduit section having one open end structured for connection to a syringe and having separate conduit segments both disposed in fluid communication with said open end,
- (b) said conduit structure further including a second conduit section removably connected to said first conduit section and including two conduit segments connected to said first conduit section,
- (c) said second conduit section including an open end structured for connection to a needle positioned and structured to allow fluid flow therethrough into and out of said conduit structure,
- (d) filter means connected in fluid communication between said first and second conduit sections for filtering out amniocytes, for examination, from said amniotic fluid,
- (e) said first and second conduit sections structured to define different paths of fluid flow between the syringe and the needle and into and out of said needle structure,
- (f) valve means mounted on said conduit structure in flow regulating relation along said different paths of fluid flow between the syringe and the needle, and
- (g) said filter means disposed in flow receiving relation along one of said different flow paths from the needle to syringe.
