Abstract
Abstract A testing device has a sample container open at one end and a sample collector which includes a tube having a first end and a second end, a piston having a first side and a second side and a hole communicating with the first and second sides, either an absorbent pad or a finger pricking mechanism affixed to the piston on the second side of the piston in fluid communication with the hole in the piston, a holding reservoir having a first end and a second end and a venting hole and a lid hingedly coupled to the holding reservoir at the second end for securing a sample of saliva in the holding reservoir. The piston fixed to the first end of the tube on the first side of the piston with the hole in fluid communication with the tube fits closely and slidably within the sample container. The absorbent pad has an exposed first portion, a second portion disposed within the piston and a third portion disposed within the tube. The venting hole allows air which is trapped in the sample collector and the sample container to escape.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A testing device comprising: a. a sample container open at one end; and b. a sample collector including: i. a tube having a first end and a second end; ii. a piston having a first side and a second side and a hole communicating with said first and second sides, said piston being fixed to said first end of said tube on said first side of said piston, said hole being in fluid communication with said tube and said piston fitting closely and slidably within said sample container; iii. an absorbent pad affixed to said piston on said second side of said piston in fluid communication with said hole in said piston; iv. a holding reservoir having a first end and a second end and a venting hole, said holding reservoir being in fluid communication at said first end with said tube at said second end of said tube whereby said venting hole allows air trapped in said sample collector and said sample container to escape; and v. a lid hingedly coupled to said holding reservoir at said second end whereby said lid secures a sample in said holding reservoir.
Claim 2
Dependent Claim
190 words
A testing device comprising: a. a sample container open at one end; and b. a sample collector including: i. a tube having a first end and a second end; ii. a piston having a first side and a second side and a hole communicating with said first and second sides, said piston being fixed to said first end of said tube on said first side of said piston, said hole being in fluid communication with said tube and said piston fitting closely and slidably within said sample container; iii. an absorbent pad affixed to said piston on said second side of said piston in fluid communication with said hole in said piston; iv. a holding reservoir having a first end and a second end and a venting hole, said holding reservoir being in fluid communication at said first end with said tube at said second end of said tube whereby said venting hole allows air trapped in said sample collector and said sample container to escape; and v. a lid hingedly coupled to said holding reservoir at said second end whereby said lid secures a sample in said holding reservoir.
Claim 3
Dependent Claim
20 words
A testing device according to claim 1 wherein said testing device also includes a cap for enclosing said sample container.
Claim 4
Dependent Claim
291 words
A testing device comprising: a. a sample container open at one end; and b. a sample collector including: i. a tube having a first end and a second end; ii. a piston having a first side and a second side and a hole communicating with said first and second sides, said piston being fixed to said first end of said tube on said first side of said piston, said hole being in fluid communication with said tube and said piston fitting closely and slidably within said sample container; iii. an absorbent pad affixed to said piston on said second side of said piston in fluid communication with said hole in said piston wherein said absorbent pad has a first portion, a second portion and a third portion, said first portion being exposed, said second portion being disposed within said piston and being enclosed thereby, and said third portion being disposed in said tube; iv. an indicator activated by a sample of saliva and disposed in said third portion so that said indicator does not interfere with the collection of said sample whereby when said first portion is inserted into a test subject's mouth saliva fluidly couples said first portion to said indicator in said third portion through said second portion; v. a holding reservoir having a first end and a second end and a venting hole, said holding reservoir being in fluid communication at said first end with said tube at said second end of said tube whereby said venting hole allows air which is trapped in said said sample collector and said sample container to escape; and vi. a lid hingedly coupled to said holding reservoir at said second end whereby said lid secures a sample in said holding reservoir.
Claim 5
Dependent Claim
291 words
A testing device comprising: a. a sample container open at one end; and b. a sample collector including: i. a tube having a first end and a second end; ii. a piston having a first side and a second side and a hole communicating with said first and second sides, said piston being fixed to said first end of said tube on said first side of said piston, said hole being in fluid communication with said tube and said piston fitting closely and slidably within said sample container; iii. an absorbent pad affixed to said piston on said second side of said piston in fluid communication with said hole in said piston wherein said absorbent pad has a first portion, a second portion and a third portion, said first portion being exposed, said second portion being disposed within said piston and being enclosed thereby, and said third portion being disposed in said tube; iv. an indicator activated by a sample of saliva and disposed in said third portion so that said indicator does not interfere with the collection of said sample whereby when said first portion is inserted into a test subject's mouth saliva fluidly couples said first portion to said indicator in said third portion through said second portion; v. a holding reservoir having a first end and a second end and a venting hole, said holding reservoir being in fluid communication at said first end with said tube at said second end of said tube whereby said venting hole allows air which is trapped in said said sample collector and said sample container to escape; and vi. a lid hingedly coupled to said holding reservoir at said second end whereby said lid secures a sample in said holding reservoir.
Claim 6
Dependent Claim
