AUTOINJECTOR WITH DESHIELDER COMPRISING TAMPER EVIDENCE MEANS
First Claim
1. A method to determine the condition and/or identity of a functional fluid comprising(1) obtaining a sample of the functional fluid;
- (2) placing the sample of the functional fluid on a medium;
(3) contacting the functional fluid sample with a reagent solution wherein the solution comprises a redox indicator in combination with an acid reducing agent wherein the acid reducing agent comprises dithiophosphoric acid, a mixture of phosphoric acid and zinc dialkyldithio-phosphate, or combinations thereof;
(4) allowing the indicator in the reagent solution with the functional fluid sample on a medium to produce a color change;
(5) analyzing the results of the reaction by determining or comparing the resultant color change; and
(6) determining the condition or identity of the functional fluid;
wherein the reagent solution is sprayed onto the sample using a pump type sprayer, an aerosol spray, or a mister.

Abstract
The invention relates to a device (1) for automatic injection of a product into an injection site, said device (1) further comprising a needle (6) and a needle shield (2) for protection of said needle (6) prior to use of said device, and a housing (300) receiving the container (50) and a deshielder (8) for removing said needle shield (2) from said device (1), said deshielder (8) being coupled to said needle shield (2) and being mounted on the housing (300) in a separable manner, for example through breakable or snap-fit means, said deshielder (8) comprising tamper evidence means that are activated by the removal of at least one part of said deshielder (8). Said at least one part of said deshielder (8) can be removed from the housing (300) by exerting a traction force equal or less to 30 N.

24. A method to determine the condition or identity of a functional fluid comprising
a. obtaining a sample of a functional fluid; -
b. placing the sample of the functional fluid upon a medium; c. contacting, spraying and/or atomizing an appropriate reagent solution with or on the media that contains the sample of the functional fluid to be tested; d. waiting for an effective period of time to allow for the reaction between the components of the functional fluid and an indicator or marker in the reagent solution; and e. making a visual determination of the sample of the functional fluid on the medium using the printed instructions and/or comparative visual indicia depicting the functional fluid in various conditions; wherein the reagent solution comprises a redox indicator in combination with an acid reducing agent;
wherein the acid reducing agent comprises dithiophosphoric acid, a mixture of phosphoric acid and zinc dialkyldithiophosphate, or combinations thereof; andwherein the reagent solution is sprayed onto the sample using a pump type sprayer, an aerosol spray, or a mister.
