Abstract
Abstract The pack for testing the efficacy of ethylene oxide sterilization has a clear plastic tray containing a sterilization sensitive ink which has been imprinted on a card which faces out of the bottom of the plastic tray. The tray contains a plastic syringe which holds a biological indicator and an absorptive material adapted to absorb moisture and ethylene oxide with the syringe. The ratio of the volume of absorptive material in the syringe to the volume of the syringe is comparable to the ratios of prior art test packs which were of much larger construction. A test pack comprising e.g. a syringe containing a biological indicator with an adsorbent member typically of sponge or blotting paper adjacent the syringe opening is also disclosed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A biological test pack for use in ethylene oxide sterilization processes comprising: (a) a tray including syringe holding means molded therein for holding a syringe containing a biological indicator; (b) indicator card holding means associated with said tray for holding an indicator card adjacent to the bottom of said tray in a position in which said indicator card is raised away from possible condensate and is visible from outside of said tray; W a syringe containing a biological indicator of the type including a glassine enclosed or a self-contained biological indicator, said syringe being held in place within said tray by said syringe holding means; (d) an indicator card having a sterilization sensitive ink imprinted thereon, said indicator card being held in said tray by said indicator card holding means with said ink imprint facing out of said tray; and (e) an absorbent member situated within said syringe adjacent the opening thereof; and M means for sealing the top of said tray until it is ready for use.
Claim 2
Dependent Claim
168 words
A biological test pack for use in ethylene oxide sterilization processes comprising: (a) a tray including syringe holding means molded therein for holding a syringe containing a biological indicator; (b) indicator card holding means associated with said tray for holding an indicator card adjacent to the bottom of said tray in a position in which said indicator card is raised away from possible condensate and is visible from outside of said tray; W a syringe containing a biological indicator of the type including a glassine enclosed or a self-contained biological indicator, said syringe being held in place within said tray by said syringe holding means; (d) an indicator card having a sterilization sensitive ink imprinted thereon, said indicator card being held in said tray by said indicator card holding means with said ink imprint facing out of said tray; and (e) an absorbent member situated within said syringe adjacent the opening thereof; and M means for sealing the top of said tray until it is ready for use.
Claim 3
Dependent Claim
15 words
The biological test pack of claim 1 wherein said absorbent member comprises an open-celled foam.
Claim 4
Dependent Claim
52 words
An article for biologically challenging (determining) the efficacy of ethylene oxide sterilization processes comprising: (a) a syringe or other container containing a biological indicator of the type including a glassine enclosed or a self-contained biological indicator; and (b) an absorbent member situated within said syringe or other container adjacent the opening thereof.
Claim 5
Dependent Claim
52 words
An article for biologically challenging (determining) the efficacy of ethylene oxide sterilization processes comprising: (a) a syringe or other container containing a biological indicator of the type including a glassine enclosed or a self-contained biological indicator; and (b) an absorbent member situated within said syringe or other container adjacent the opening thereof.
Claim 6
Dependent Claim
32 words
A test pack according to claim 1 in which the tray is of clear colourless plastics material, and in which the combination (a) - (e) creates a flow rate limiting tortuous opening.
