Abstract

A test strip port connector of a test meter receives an analytical test strip comprising a sample chamber for receiving a fluid sample. The fluid sample is prevented from contaminating an interior region of the test strip port connector by a sealing mechanism having a seal configured to be moved into a sealing position across the test strip.

Claims

1. An analyte test meter comprising:

a test strip port connector configured for receiving an analytical test strip, said port connector comprising at least one electrical contact for engaging at least one electrical contact pad of the received analytical test strip, the received analytical test strip further comprising a sample chamber for receiving a fluid sample; and

said port connector defining an interior and having a movable portion that permits a test strip to be inserted into the connector when the movable portion is moved to an open position, said connector further including at least one seal element configured for sealing the test strip port connector against ingress therein by the fluid sample, wherein the sealing mechanism is configured to be moved into a sealing position across the inserted test strip when the movable portion is moved to a closed position about the inserted test strip;

wherein movable portion is hingably connected to the port connector and is configured to be moved manually between the open and closed positions; and

further comprising a motor configured for automatically moving the movable portion of the port connector between the open and closed positions.

2. A test meter comprising:

a test strip port connector comprising an electrical contact for engaging a contact pad of a first analytical test strip, the first analytical test strip comprising the contact pad at a first end thereof and a sample chamber at an opposite end thereof;

said port connector having a portion that is movable between an open position and a closed position for allowing access to an enclosure defined by the port connector wherein moving the movable portion to the closed position secures the test strip in engagement with the electrical contact and creates a fluidic seal to prevent ingress of fluid into the test meter;

a housing for storing the first analytical test strip therein; and

a slider operable to insert the first analytical test strip from the housing into the test strip port connector and for engaging the electrical contact with the contact pad of the first analytical test strip.

3. The test meter of claim 2, further comprising a second analytical test strip stored in the housing together with the first analytical test strip, wherein the second analytical test strip is configured to be inserted from the housing into the test strip port connector using the slider.

4. A test meter comprising:

a test strip port connector comprising an electrical contact for engaging a contact pad of a first analytical test strip, the first analytical test strip comprising the contact pad at a first end thereof and a sample chamber at an opposite end thereof;

said port connector having a portion that is movable between an open position and a closed position for allowing access to an enclosure defined by the port connector wherein moving the movable portion to the closed position secures the test strip in engagement with the electrical contact and creates a fluidic seal to prevent ingress of fluid into the test meter; and

wherein the port connector includes at least one seal element for said securing the test strip in engagement with the electrical contact and for sealing the electrical contact from the sample chamber;

wherein the test strip port connector comprises a first seal element disposed on an interior surface of the movable portion and a second seal element on an interior surface of a corresponding portion of the port connector such that moving the movable portion to the closed position causes the first and second seal elements to sealingly engage corresponding surfaces of an inserted test strip;

wherein the first and second seal elements are disposed directly opposite each other such that the first and second seal elements engage corresponding opposite surfaces of the inserted test strip when the movable portion is moved to the closed position; and

wherein the movable portion is connected to the port connector by a hinge, and wherein the movable portion is moved into the open and closed positions by rotating the movable portion about the hinge; and

further comprising a motor for said rotating the movable portion about the hinge.

5. The test meter of claim 4, wherein said first and second seal elements are made from a pliable rubber.
