Tamper evident cap for medical fitting
A tamper evident closure assembly for a fitting including, but not limited to, use in combination with a female fixture or an enteral fixture. A cap is connectable in flow restricting relation to the fitting and includes an indicator member removably connected to an exterior thereof. A housing is dimensioned to removably contain the cap and the connected indicator member. Subsequent to the fixture being connected to the cap, a removal thereof results in the indicator member being detached from the cap and movably disposed in a captured, detached orientation within the housing. Tampering may be evidenced by the indicator member remaining captivated within the housing which may be determined by visual observation or the generation of sound caused resulting from the housing being shaken. An included drive assembly is structured for concurrent rotation of the housing and the indicator member one direction and relative movement there between upon rotation of at least a housing in an opposite direction.
1. A tamper evident closure assembly for a medical fitting, said closure assembly comprising:
a cap connectable in flow restricting relation to the medical fitting,
an indicator member removably connected to an exterior of said cap,
a housing including an at least partially hollow interior and an access opening,
said cap movably and removably disposed within said hollow interior concurrent to connection to the medical fitting,
said indicator member movable with said cap when connected thereto and movably disposed in a detached relation from said cap in a captured, detached orientation within said housing, upon removal of said cap from said housing, and
a viewing structure formed in a sidewall of said housing and disposed and structured to define a visual observation of components within said housing.
2. The closure assembly as recited in claim 1 wherein said viewing structure comprises said sidewall of said housing being at least partially formed from a substantially transparent material.
3. The closure assembly as recited in claim 1 wherein said viewing structure comprises a viewing port integrally formed in said sidewall.
4. The closure assembly as recited in claim 3 wherein said viewing structure is disposed to establish said visual observation of said indicator member when in said captured, detached orientation within said housing.
5. The closure assembly as recited in claim 4 further comprising at least one retaining member disposed and structured to retain said indicator member in said visual observation when in said captured, detached orientation.
6. The closure assembly as recited in claim 3 wherein said viewing port is disposed to establish said visual observation with said indicator member when in said captured, detached orientation within said housing; said visual observation being indicative of removal of said cap from said housing.
7. The closure assembly as recited in claim 6 wherein a non-visual observation of said indicator member through said viewing port is indicative of non-removal of said cap from said housing.
8. The closure assembly as recited in claim 3 wherein said indicator member comprises an identifier disposed thereon and structured to visually distinguish said indicator from at least one of said components within said housing.
9. The closure assembly as recited in claim 8 wherein said identifier comprises a color coding.
