Abstract
A fluidic sample test apparatus has a mounting part such that the temperature of a fluidic sample, which is inserted into the mounting part, is uniformly maintained. The fluidic sample test apparatus includes a main body having a mounting part into which a sample cartridge is inserted, a metal panel disposed on one surface of the mounting part, and a printed circuit board (PCB) disposed on another surface of the mounting part facing the one surface. One side of the metal panel is in contact with the PCB.
Core Innovation
A fluidic sample test apparatus includes a main body with a mounting part into which a sample cartridge is inserted. The mounting part has a first surface and a second surface facing the first surface, a metal panel is disposed on the first surface, and a printed circuit board (PCB) is disposed on the second surface, with one side of the metal panel in contact with the PCB.
The metal panel is configured so that heat can be transferred through the test portion via structural contact with the PCB. The metal panel has at least one bent portion that contacts the second side of the PCB opposite to a first side of the PCB, thereby establishing an opposite-side contact interface, and a heating member is disposed at a first side of the PCB.
The mounting part can further include first and second panels spaced apart and facing each other. The PCB is mounted on the second panel, the heating member is disposed on the PCB, and the first panel includes at least one metal portion made of a metallic material that can contact a surface of the inserted sample cartridge.
Claims Coverage
The independent claims are directed to a fluidic sample test apparatus with three inventive features.
Opposed metal panel and PCB in the cartridge mounting part
A main body having a mounting part into which a sample cartridge is inserted, the mounting part having a first surface and a second surface facing the first surface; a metal panel disposed on the first surface of the mounting part; and a printed circuit board (PCB) disposed on the second surface of the mounting part, wherein one side of the metal panel is in contact with the PCB.
Bent metal portion contacting an opposite PCB side with PCB heating member
A main body having a mounting part into which a sample cartridge is inserted, the mounting part having a first surface and a second surface facing the first surface; a metal panel disposed on the first surface of the mounting part; and a printed circuit board (PCB) disposed on the second surface of the mounting part; a heating member disposed at a first side of the PCB, wherein the metal panel has at least one bent portion that contacts a second side of the PCB that is opposite to the first side of the PCB.
First and second panels with PCB-mounted heating member and metallic first panel portion
A main body having a mounting part into which a sample cartridge is inserted, wherein the mounting part comprises: a first panel; a second panel spaced apart from and facing the first panel; a printed circuit board (PCB) mounted on the second panel; and a heating member disposed on the PCB, wherein the first panel has at least one metal portion made of a metallic material.
Across the independent claims, the apparatus centers on a mounting part with a metal panel on one mounting surface and a PCB on the facing surface, with a metal-to-PCB contact implemented directly or via a bent portion contacting an opposite PCB side, and a heating member disposed on a PCB side.
