Sample testing device with funnel collector
First Claim
Patent Images
1. A sample testing device comprising:
- a buffer container having an interior which receives a buffer fluid therein;
a funnel collector having a securement;
a test strip having an end held by said securement;
a test strip container having a receptacle dimensioned and disposed to accommodate said funnel collector, so that when said funnel collector is accommodated by said test strip container, the test strip is disposed in said receptacle;
a sample collector for holding a sample therein and which is shaped to receive said buffer container, said sample collector having a channeling member having a lumen, and a piercing member which, when said buffer container is placed in said sample collector, pierces said buffer container so that the buffer fluid in the interior of the buffer chamber contacts the sample and passes through the lumen to said funnel collector;
wherein as the buffer fluid flows through the lumen of the sample collector the buffer fluid that has contacted the sample accumulates in said funnel collector and contacts said end of the test strip.

Abstract
The present invention provides a funnel collector for use with a sample testing device. The funnel collector collects and holds a fluid sample in order to place the sample in immediate contact with a diagnostic test strip, which reacts with the sample in a known fashion.

13. A sample testing device comprising:
-
a buffer container having an interior which receives a buffer fluid therein; a sample collector for holding a sample therein and having a top opening shaped to receive said buffer container, a bottom opening shaped to receive a funnel collector, and a piercing member positioned therein which, when said buffer container is placed in said top opening of said sample collector, pierces said buffer container so that the buffer fluid in the interior of the buffer container contacts the sample the funnel collector having both a top and a bottom portion, wherein said top portion of said funnel collector is shaped to fit into said bottom opening of said sample collector, and wherein said bottom portion of said funnel collector engages a test strip; a test strip container having a receptacle dimensioned and disposed to accommodate said funnel collector, so that when said funnel collector is accommodated by said test strip container, said test strip is disposed in said receptacle; wherein as said buffer fluid flows through said sample collector into the funnel collector, the buffer fluid that has contacted the sample passes to the funnel collector and contacts said test strip. - View Dependent Claims (14, 15, 16, 17)

18. A sample testing device comprising:
-
a buffer container having an interior which receives a buffer fluid therein; a funnel collector; a test strip; a test strip container having a receptacle dimensioned and disposed to accommodate said funnel collector, so that when said funnel collector is accommodated by said test strip container, the test strip engages said funnel collector and is disposed in said receptacle; and a sample collector for holding a sample therein and having a top opening shaped to receive said buffer container, a bottom opening, a pumping mechanism which draws air toward the pumping mechanism through an air passage, and a piercing member which, when said buffer container is placed in said sample collector, pierces said buffer container so that the buffer fluid in the interior of the buffer container contacts the sample and passes through the bottom opening to said funnel collector; whereby when said pumping mechanism draws air through said air passage, a sample of a fluid is drawn into said sample collector through said bottom opening, wherein as the buffer fluid flows through the sample collector the buffer fluid contacts the sample and passes to said funnel collector and contacts said test strip. - View Dependent Claims (19, 20, 21, 22, 23)
