Sample testing device
First Claim
1. A sample testing device, comprising:
- a buffer container having an interior which receives a buffer fluid therein and a weakened portion;
a test strip having an end;
a filter holding the end of the 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 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, wherein when the buffer container is squeezed, the weakened portion fails and 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 contacts the sample and then flows directly 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.

13. A sample testing device, comprising:
-
a buffer container having an interior which receives a buffer fluid therein and a weakened portion; a test strip having an end; a filter holding the end of the test strip, the test strip positioned below the filter when the testing device is positioned in an upright manner; 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, the test strip being held by the filter so as not to be in contact with sides of said receptacle when the testing device is positioned in an upright manner; a sample collector holding a sample between the buffer container and the filter, wherein when the weakened portion is caused to fail, then the buffer fluid flows into contact with the sample and then flows directly through the filter to the test strip.
