Molecular diagnostics amplification system and methods
First Claim
1. A nucleic acid amplification device comprising:
- a housing; and
an amplification chamber comprising;
an ingress with a first reversible seal;
an egress with a second reversible seal;
a sealable sample entry orifice; and
a first wall forming a portion of the amplification chamber,wherein the first wall comprises a thermally conductive material and includes a first surface and a second surface,wherein the second surface includes a heating circuit and a temperature sensor,wherein the sample entry orifice permits a sample of nucleic acid to enter the amplification chamber,wherein the ingress is connected to a first conduit along with a reservoir comprising a first flexible diaphragm and a fluid pouch for performing nucleic acid amplification, and a pump comprising a pneumatic pump and a second flexible diaphragm,wherein the first flexible diaphragm is configured to engage and be actuated by a plunger on an instrument with which the amplification device is configured to mate,wherein the second flexible diaphragm is configured to engage and be actuated by a plunger on an instrument with which the amplification device is configured to mate, andwherein the egress is connected to a second conduit permitting egress of an amplicon from the amplification chamber.

Abstract
The present invention relates to automated devices and methods for the amplification of segments of nucleic acid in a convenient and portable manner. A single-use nucleic acid amplification device for producing an amplicon includes a housing and an amplification chamber. The chamber includes an ingress with a first reversible seal, an egress with a second reversible seal, a sealable sample entry orifice, and a first wall forming a portion of the chamber. The first wall includes a thermally conductive material and includes an interior surface and an exterior surface. The exterior surface includes a heating circuit and a temperature sensor. The sample entry orifice permits a sample of nucleic acid to enter the amplification chamber. The ingress is connected to a first conduit along with a pneumatic pump and a fluid pouch. The egress is connected to a second conduit permitting egress of the amplicon from the amplification chamber.
