Patent ID: 7754452

Claim:
A polymerase chain reaction (PCR) module, comprising: a detachable PCR chip including a PCR chamber unit in which a PCR solution is accommodated; a heater unit heating the PCR solution in the PCR chip with a preset temperature; a detecting unit detecting unit detecting a PCR signal of the PCR solution; and a PCR chip installation unit mounting and detaching the PCR chip to and from the PCR module using a one-touch method, respectively, in which the heater unit of the PCR module is adhered to the PCR chip with a predetermined pressure when mounting the PCR chip to the PCR module, and the heater unit of the PCR module is separated from the PCR chip when detaching the PCR chip from the PCR module; a housing covering at least the heater unit and the detecting unit so that they are not exposed to the outside; wherein the PCR chip installation unit comprises: a heater mounting guide for adhering the heater unit to the PCR chip with the predetermined pressure when mounting the PCR chip; a push rod which enables the PCR chip to be mounted by locking the heater mounting guide when the PCR chip is not yet mounted, and enables the heater mounting guide to adhere the heater unit to the PCR chip by releasing the heater mounting guide when mounting the PCR chip; a detaching button to draw back the heater unit to separate the heater unit from the PCR chip when detaching the PCR chip; a cover encompassing the heater unit and the heater mounting guide to provide a safe movement path for the PCR chip when mounting or detaching the PCR chip and to protect the PCR chip; and a flat chip guide disposed between the cover and the heater unit to form the movement path for the PCR chip together with the cover; wherein a curved protrusion corresponding to the width and height of the PCR chip is formed in the center of the cover, and the PCR chip moves between the curved protrusion of the cover and the chip guide.
