Sample testing device
First Claim
1. A sample testing device, comprising:
- a buffer container having an interior which receives a buffer fluid therein;
a filter 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 filter, so that when said filter 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 container contacts the sample and passes through the lumen to said filter;
wherein as the buffer fluid flows through the lumen of the sample collector the buffer fluid that has contacted the sample passes through the filter to the test strip.

Abstract
A sample testing device has a buffer container that can hold buffer fluid, a filter with a securement for holding a test strip, the test strip, a test strip container having a receptacle to accommodate the filter, so that when the filter is held therein the test strip is disposed in the receptacle, and a sample collector for holding a sample. The sample collector receives the buffer container, and the sample collector has a piercing member which, when the buffer container is placed in the sample collector, pierces the buffer container. Buffer fluid in the buffer container then contacts the sample. As buffer fluid flows through the sample collector, the buffer fluid that has contacted the sample passes through the filter to the test strip.

11. 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 filter, 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;
a filter having both a top and a bottom portion, wherein said top portion of said filter is shaped to fit into said bottom opening of said sample collector, and wherein said bottom portion of said filter contacts a test strip;
a test strip container having a receptacle dimensioned and disposed to accommodate said filter, so that when said filter 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 filter the buffer fluid that has contacted the sample passes through the filter to the test strip. - View Dependent Claims (12, 13, 14, 15, 16)

17. A sample testing device, comprising:
-
a buffer container having an interior which receives a buffer fluid therein;
a filter;
a test strip;
a test strip container having a receptacle dimensioned and disposed to accommodate said filter, so that when said filter is accommodated by said test strip container, the test strip contacts the filter 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 filter;
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 from the filter to the test strip. - View Dependent Claims (18, 19, 20, 21, 22, 23)
