Abstract

An adaptor is provided to facilitate delivery of a fluid specimen from a syringe to a point-of-care testing cartridge. The adaptor includes a mounting sleeve for snapped engagement over a portion of the testing cartridge, including the entry port to the testing cartridge. The adaptor further includes a Luer fitting unitarily formed with the mounting sleeve. The Luer fitting has an inlet end configured for mating with the syringe and an outlet end configured for alignment with the entry port of the testing cartridge. The adaptor can be snapped onto the testing cartridge. The Luer tip of the syringe then can be mated with the Luer fitting of the adaptor for safe and convenient delivery of the specimen through the adaptor and into the testing cartridge.

Claims

1. An adaptor for use with a testing cartridge and a syringe to facilitate delivery of a fluid specimen from said syringe to said testing cartridge, said testing cartridge having a bottom wall, a top wall and at least one side wall extending between said top and bottom walls, an entry port extending through said top wall for delivering the specimen to the testing cartridge, said adaptor comprising a mounting sleeve configured for slidable mounting over portions of said top and bottom wall of said testing cartridge including portions of said top wall having said entry port therein, at least one locking detent formed on said mounting sleeve for locked engagement with said testing cartridge, and a Luer filling having an outlet end extending through said mounting sleeve at a location for alignment with said entry port when said mounting sleeve is mounted on said testing cartridge, an inlet end spaced from said outlet end and a passage extending between said ends, said passage having at least one non-linear portion so that said inlet end is aligned at an angle to said outlet end, said inlet end being configured for fluid-tight mounting with said syringe.

2. The adaptor of claim 1, wherein the mounting sleeve comprises a bottom wall for slidable engagement with said bottom wall of said testing cartridge and a top wall configured for sliding engagement with said top wall of said testing cartridge, said locking detents being formed respectively on said top and bottom walls of said adaptor.

3. The adaptor of claim 2, wherein said mounting sleeve further comprises a side wall extending between said top and bottom walls and disposed for slidable engagement against said side wall of the testing cartridge.

4. The adaptor of claim 3, further comprising an end wall extending between said top and bottom walls and angularly aligned to said side wall.

5. The adaptor of claim 1, wherein portions of said passage adjacent said inlet end of said Luer fitting define a conical taper configured for mating with a Luer tip of said syringe.

6. The adaptor of claim 5, wherein portions of said Luer fitting adjacent said inlet end include a pair of projections configured for threaded engagement with a Luer collar on said syringe.

7. A adaptor for use with a testing cartridge and a syringe to facilitate delivery of a fluid specimen from said syringe to said testing cartridge, said testing cartridge having a bottom wall, a top wall and at least one side wall extending between said ton and bottom walls, an entry port extending through said top wall for delivering the specimen to the testing cartridge, said adaptor comprising a mounting sleeve configured for slidable mounting over portions of said too and bottom wall of said testing cartridge including portions of said too wall having said entry port therein, and a Luer fitting having an outlet end extending through said mounting sleeve at a location for alignment with said entry port when said mounting sleeve is mounted on said testing cartridge, an inlet end spaced from said outlet end and a passage extending between said ends, said inlet end being configured for fluid-tight mounting with said syringe, the mounting sleeve having a bottom wall for slidable engagement with said bottom wall of said testing cartridge and a too wall configured for sliding engagement with said too wall of said testing cartridge, locking detents being formed respectively on said too and bottom walls of said adaptor for locked engagement with said testing cartridge, wherein portions of said passage through said Luer fitting adjacent said inlet end of said Luer fitting are aligned substantially parallel to said bottom wall.

8. The adaptor of claim 7, wherein portions of said passage through said Luer fitting adjacent said outlet end of said Luer fitting are aligned substantially orthogonal to said bottom wall of said adaptor.

9. An adaptor for use with a testing cartridge and a syringe to facilitate delivery of a fluid specimen from said syringe to said testing cartridge, said adaptor comprising a mounting sleeve having a substantially planar bottom wall with at least one locking detent formed thereon for snapped engagement with said testing cartridge, side and end walls projecting from said bottom wall for positioning said mounting sleeve relative to said testing cartridge, a top wall extending from said side and end walls in spaced relationship to said bottom wall, a Luer fitting unitarily formed with said top wall, said Luer fitting having an inlet section with an inlet end, said inlet section being aligned substantially parallel to said bottom wall, said Luer fitting further having an outlet section with an outlet end aligned substantially orthogonally to said bottom wall, a passage extending continuously between said inlet end and said outlet end of said Luer fitting, portions of said passage adjacent said inlet end being configured for mating with a Luer tip of said syringe.
