Abstract

A decontamination system including a test fixture configured to engage an endoscope in order to retain the test fixture thereto, wherein the endoscope can comprise a valve chamber and a valve removable from the valve chamber such that the test fixture can be inserted therein. The test fixture can comprise, first, a frame having a first gripping portion and a valve member analog extending from the frame, and, second, a housing having a second gripping portion movable relative to the frame between a locked position and an unlocked position, wherein the second gripping portion is configured to be moved toward the first gripping portion to position the housing in its unlocked position. The second gripping portion can be configured to be moved away from the first gripping portion to position the housing in its locked position such that the housing can engage a locking feature on the endoscope.

First claim

What is claimed is:

1. A test fixture, comprising:
a frame having a first gripping portion;
a valve member analogue extending from said frame, wherein said valve member analogue includes a seal configured to seal at least a portion of a valve chamber of an endoscope when a removable valve of the endoscope is removed from the valve chamber, and another seal configured to separate a first channel of the valve chamber of the endoscope from a second channel of the valve chamber of the endoscope when the removable valve of the endoscope is removed from the valve chamber;
another valve member analogue extending from said frame, wherein said valve member analogue and said another valve member analogue define a longitudinal axis extending substantially therebetween;
retainers attached to said frame and holding said valve member analogues to said frame, wherein said retainers prevent said valve member analogues from moving relative to said frame;
a housing movable relative to said frame, wherein said frame is located within said housing and said housing is movable substantially perpendicular to said longitudinal axis between a locked position and an unlocked position, wherein said housing comprises a second gripping portion, wherein said second gripping portion is configured to be moved toward said first gripping portion to position said housing in said unlocked position, wherein said second gripping portion is configured to be moved away from said first gripping portion to position said housing in said locked position, and wherein said housing comprises a second locking feature configured to engage a first locking feature of the endoscope when said second gripping portion is moved away from said first gripping portion.

2. The test fixture of claim 1 , further comprising a spring positioned intermediate said housing and said frame, wherein said spring is configured to bias said housing substantially perpendicular to said longitudinal axis into said locked position.

3. The test fixture of claim 1 , further comprising:
a lifting member movable relative to said frame, wherein said lifting member is movable between a first position and an extended position, and wherein said lifting member is configured to engage the endoscope when said lifting member is in said extended position; and
a spring positioned intermediate said lifting member and said frame, wherein said spring is configured to apply a biasing force to said lifting member to move said lifting member into said extended position.

4. The test fixture of claim 3 , wherein said frame includes a midline, wherein said lifting member is positioned on one side of said midline, and wherein said lifting member and said spring are configured to tilt said frame relative to the endoscope when said lifting member is in said extended position.

5. The test fixture of claim 3 , wherein said housing is configured to retain said lifting member in said first position when said housing is in said locked position, and wherein said housing includes a slot configured to permit said spring to move said lifting member into said extended position when said housing is moved into said unlocked position.

6. The test fixture of claim 1 , wherein said valve member analogue comprises a disposable valve member analogue removably connected to said frame.

7. The test fixture of claim 1 , wherein the endoscope includes a plurality of first locking features and a plurality of valve chambers, wherein said valve member analogue and said another valve member analogue are configured to correspond with a corresponding said valve chamber, and wherein said housing further comprises a plurality of second locking features configured to engage said plurality of first locking features.

8. A test fixture, comprising:
a frame;
a valve member analogue extending from said frame, wherein said valve member analogue includes a first seal and a second seal, wherein the first and second seals are configured to seal at least a portion of a valve chamber of an endoscope when a removable valve of the endoscope is removed from the valve chamber;
another valve member analogue extending from said frame, wherein said valve member analogue and said another valve member analogue define a longitudinal axis extending substantially therebetween;
retainers attached to said frame and holding said valve member analogues to said frame, wherein said retainers prevent said valve member analogues from moving relative to said frame;
a housing movable relative to said frame, wherein said frame is located within said housing and said housing is movable substantially perpendicular to said longitudinal axis toward said frame to position said housing in an unlocked position; and
a biasing member configured to bias said housing to said frame substantially perpendicular to said longitudinal axis to position said housing in a locked position in which said housing is locked to a locking feature of the endoscope.

9. The test fixture of claim 8 , further comprising:
a lifting member movable relative to said frame, wherein said lifting member is movable between a first position and an extended position, and wherein said lifting member is configured to engage the endoscope when said lifting member is in said extended position; and
a spring positioned intermediate said lifting member and said frame, wherein said spring is configured to apply a biasing force to said lifting member to move said lifting member into said extended position.

10. The test fixture of claim 9 , wherein said frame includes a midline, wherein said lifting member is positioned on one side of said midline, and wherein said lifting member and said spring are configured to tilt said frame relative to the endoscope when said lifting member is in said extended position.

11. The test fixture of claim 9 , wherein said housing is configured to retain said lifting member in said first position when said housing is in said locked position, and wherein said housing includes a slot configured to permit said spring to move said lifting member into said extended position when said housing is moved into said unlocked position.

12. The test fixture of claim 8 , wherein said valve member analogue comprises a disposable valve member analogue removably connected to said frame.

13. The test fixture of claim 8 , wherein the endoscope includes a plurality of locking features and a plurality of valve chambers, wherein said valve member analogue and said another valve member analogue are configured to correspond with a corresponding said valve chamber, and wherein said housing is configured to be locked to said plurality of locking features.

14. A test fixture, comprising:
a frame;
a valve member analogue extending from said frame, wherein said valve member analogue includes a seal configured to seal at least a portion of a valve chamber of an endoscope when a removable valve is removed from the valve chamber, and wherein said seal is configured to separate a first channel of the valve chamber of the endoscope from a second channel of the valve chamber of the endoscope;
another valve member analogue extending from said frame, wherein said valve member analogue and said another valve member analogue define a longitudinal axis extending substantially therebetween;
retainers attached to said frame and holding said valve member analogues to said frame, wherein said retainers prevent said valve member analogues from moving relative to said frame; and
a housing configured to lock the test fixture to the endoscope, wherein said frame is located within said housing.

15. The test fixture of claim 14 , further
