Abstract

A valve (10), which includes a stem (32) having a slit (52) at an end thereof. The valve stem (32) is located in a valve body (12) and is deformable. When a tip (56) of an instrument (22) is engaged with a slit (52) in the stem (32), the stem (32) shifts in the body (12), top portion folds inward, the slit (52) seals against the instrument (22) and allows liquid to flow through the stem (32), to or from the instrument (22). All components have circular cross sectional geometry.

Claims

AMENDED CLAIMS[received by the International Bureau on 09 July 2003 (09.07.03); original claims 1, 11 and 21 amended; remaining claims unchanged (5 pages)]We Claim:
1. A slit-typc swabable valve comprising: a valve body having an end; and a resilient,
deformable valve stem which is located in said valve body and is shiflabl therein, said
valve stem having an end and an exterior surface, said valve stem having a slit at said end
and having a notch on said exterior surface, said notch providing a point of weakness, said notch configured to provide that, when the valve stem shifts in the valve body upon
actuation of the valve, the valve stem buckles generally outwardly, at the notch, thereby providing increased flow volume within the valve stem, wherein said end of said valve
stem is proximate said end of said valve body when said valve stem is not shifted, such that said end of said valve stem is readily accessible for cleaning, wherein the valve docs
not include an internal cannula which engages said valve stem, wherein said slit in said valve ste is normally closed.
2. A slit-type swabable valve as recited in claim 1 , wherein both the valve body and valve stem are uniformly round and have a uniformly round cross-sectional profile.
3. A slit-typc swabable valve as recited in claim 1 , wherein the notch on the valve stem comprises a circumferential notch.
4. A slit-typc swabable valve as recited in claim 1 , wherein the valve is configured to be
actuated via engagement with a male component or instrument, wherein when the valve is actuated, the valve stem sliif in the valve body, and the slit of the valve stem seals against an outer surface of the male component or instrument, thus allowing liquid to flow through the valve stem.
25
5. A slit-type swabable valve as recited in claim 1 , wherein the valve is configured such that when the valve is actuated, fluid is flowable in either direction through the valve.
6. A slit-type swabable valve as recited in claim 1, wherein the valve is configured such that when the valve is not actuated, the slit in the valve stem is closed, thereby preventing
fiuid from leaking into or out of an end of the valve stem.
7. A slit-type swabable valve as recited in claim 1, wherein the valve is configured to be actuated via engagement with a male component or instrument, and wherein the valve stem is configured to swab or cleans a tip of the male component or instrument upon the tip being removed from the slit.
S. Λ slit-type swabable valve as recited in claim 1, wherein the valve includes a fluid flow
area and neither the valve body nor the valve stem includes any ribs which are disposed in the fluid flow area.
9. A slit-type swabable valve as recited in claim 1 , wherein the end of the stem is flat and wrinkle-free.
10. A slit-type swabable valve as recited in claim 1 , wherein said valve body has an end
which provides an opening in which siLs the valve stem, said end of said valve body providing a convey area which leads into the valve.
11. A slit-typc swabable valve comprising: a valve body having an end; and a resilient, deformable valve stem which is located in said valve body and is shiftable therein, said
valve stem having an end and an exterior surface, said valve stem having a slit at said end and having a notch on said exterior surface, said notch providing a point of weakness, said notch configured to provide that, when the valve stem shifts in the valve body upon actuation of the valve, the valve stem buckles generally outwardly, at the notch, thereby providing increased flow volume within the valve stem, wherein the valve stem is configured to collapse and fold inward generally about a fulcrum point which is located at
an area of minimal wall thickness, wherein said end of said valve stem is proximate said end of said valve body when said valve stem is not shifted, such that said end of said
valve stem is readily accessible for cleaning, wherein the valve does not include an
internal cannula which engages said valve stem, wherein said slit in said valve stem is normally closed.
12. A slit- type swabable valve as recited in claim 1 1 , wherein both the valve body and valve stem are uniformly round and have a uniformly round cross-sectional profile.
13. A slit-type swabable valve as recited in claim 11 , wherein the notch on the valve stem comprises a circumferential notch.
14. A slit-type swabable valve as recited in claim 11 , wherein the valve is configured to be actuated via engagement with a male component or instrument, wherein when the valve is actuated, the valve stem shifts in the valve body, and the slit of the valve stem seals against an outer surface of the male component or instrument, thus allowing liquid to flow through the valve stem,
15. A silt- type swabable valve as recited in claim 11, wherein the valve is configured such
that when the valve is actuated, fluid is flowable in either direction through the valve.
16. A slit-type swabable valve as recited in claim 11 , wherein the valve is Configured such thai when the valve is not actuated, the slit in the valve stem is closed, thereby preventing fluid from leaking into or out of an end of the valve stem.
27
17. A slit-type swabable valve as recited in claim 1 1 , wherein the valve is configured to be
actuated via engagement with a male component or instrument, and wherein the valve stem is configured to swab or cleans a tip of the male component or instrument upon the tip being removed from the slit.
18. A slit-type swabable valve as recited in claim 1 1 , wherein the valve includes a fluid flow
area and neither the valve body nor the valve stem includes any ribs which are disposed in the fluid flow area,
19. A slit-type swabable valve as recited in claim 11, wherein the end of the stem is flat and wπnkle-free.
20. Λ slit-type swabable valve as recited in claim 11 , wherein said valve body has an end
which provides an opening in which sits the valve stem, said end of said valve body piυviding a convex area which leads into the valve.
21. A slit-type swabable valve comprising: a valve body having an end; and a resilient, deformable valve stem which is located in said valve body and is shiftable therein, said valve stem having an end and an exterior surface, said valve stem havmg a slit at said end
and having a notch on said exterior surface, said notch providing a point of weakness, said notch configured to provide that, when the valve stem shifts in the valve body upon
actuation of the valve, the valve stem buckles generally outwardly, at the notch, thereby providing increased flow volume within the valve stem, wherein the valve stem collapses
and folds inward generally about a fulcrum point which is located at an area of minimal
wal I thickness, wherein both the valve body and valve stem are uniformly round and have
a uniformly round cross-sectional profile, wherein said end of said valve stem is
28 proximate said end of said valve body when said valve stem is not shifted, such that said
end of said valve stem is readily accessible for cleaning, wherein the valve does not include an internal cannula winch engages said valve stem, wherein said slit in said valve
