Test strip holder and method of use
First Claim
1. A test strip holding apparatus, comprising:
- an elongated hollow member having an open end and a closed end;
a support configured to hold a test strip within the elongated hollow member in a position spaced from inner walls of the elongated hollow member; and
at least one vent positioned between the open end and the closed end, said at least one vent being spaced from the open end and the closed end,wherein said at least one vent vents the elongated hollow member at a distance from the closed end and by air pressure in the closed end limits a maximum height that a liquid can travel through said elongated hollow member from said open end toward said closed end other than by capillary force along a test strip when said open end is dipped into said liquid.

Abstract
A test strip holder includes an elongated hollow member having an open end and a closed end. A support is provided that positions a test strip within the elongated hollow member spaced from inner walls of the elongated hollow member. At least one vent is positioned between the open end and the closed end of the elongated hollow member. The distance from the open end to the at least one vent opening defines the maximum height of liquid able to enter the elongated hollow member from the open end other than by capillary action. The elongated member may be formed as a tubular conduit. Alternatively, the elongated member may include a test strip receiving part and a test strip covering part, wherein the test strip receiving part may or may not be hingedly connected to the test strip covering part.

17. A method of testing a liquid using a test strip within a test strip holder, the method comprising the steps of:
-
supporting a test strip within an elongated hollow member having an open end, a closed end and a sidewall with at least one vent in the sidewall between and spaced from the open end and the closed end, the test strip being spaced from inner walls of the elongated hollow member; immersing the elongated hollow member into a liquid to be tested to at least a depth of the at least one vent, wherein said at least one vent vents the elongated hollow member at a distance from the closed end and by air pressure in the closed end limits a maximum height that said liquid travels through said elongated hollow member from said open end toward said closed end other than by capillary force along said test strip when said open end is dipped into said liquid; and observing an effect of the liquid on the test strip above the at least one vent. - View Dependent Claims (18, 19, 20)

21. A test strip holding apparatus, comprising:
-
means for supporting a test strip within and spaced from inner walls of means for receiving a test strip having an open end and a closed end; means for venting the means for receiving between the open end and the closed end and at a distance from the closed end which by air pressure in the closed end limits a maximum height that a liquid can travel through said receiving means from said open end toward said closed end other than by capillary force along a test strip as the open end of the means for receiving is dipped into the liquid, said venting means being spaced from the open end and the closed end; and means for observing the effect of the liquid on the test strip. - View Dependent Claims (22, 23)

24. A method for testing a liquid, comprising:
-
supporting a test strip within and spaced from inner walls of means for receiving a test strip having an open end and a closed end; venting the means for receiving through means for venting between the open end and the closed end and at a distance from the closed end to limit, by air pressure in the closed end, a maximum height that a liquid can travel through said receiving means from said open end toward said closed end other than by capillary force along a test strip as the open end of the means for receiving is dipped into the liquid, the means for venting being spaced from the open end and the closed end; and observing the effect of the liquid on the test strip.
