Fluid sample testing system
First Claim
1. A sample testing system, comprising:
- a housing;
a cavity in the housing, so sized and shaped to receive a chamber;
a first contact member, so positioned;
as to be engageable with a first flexible segment of the chamber when the chamber is in the cavity; and
as to compress the first flexible segment, thereby driving fluid flow from the first flexible segment through a central segment of the chamber to a second flexible segment of the chamber;
a second contact member so positioned;
as to be engageable with the second flexible segment of the chamber when the chamber is in the cavity; and
as to compress the second flexible segment, thereby driving fluid flow from the second flexible segment through the central segment to the first flexible segment; and
a sensor to sense a condition of a fluid sample in the chamber and to generate an output signal indicative of that condition.

Abstract
A sample testing system may include a housing, a cavity in the housing to receive a chamber, two contact members, and a sensor. The contact members may be positioned to be engageable with respective portions of the chamber inserted in the cavity, and to compress those respective portions, thereby driving fluid flow. A sample testing system may include a housing, a cavity in the housing to receive a chamber, at least one contact member, and a sensor. The at least one contact member may be positioned to be engageable with a first segment of the chamber when the chamber is in the cavity, and to compress the first segment, thereby defining a gap of the first segment of the chamber and a reservoir in at least a second segment of the chamber.
