The present disclosure, among other things, describes a reader system for analyzing one or more analytes in a fluid sample, comprising a casing (204) with at least one port (201) leading to a holster (301) which is configured to receive a cartridge (107) comprising a vertically oriented immunoassay device for analyzing one or more analytes in a fluid sample, an optical system (121) with excitation optics comprising a light source (302) and an excitation lens (305) configured to transmit light from the light source (302) and thereby excite a region of the vertically oriented immunoassay device when a cartridge (107) is placed in the holster (301), and collection optics comprising a photosensor (306) and a collection lens (307) configured to collect emitted light from the vertically oriented immunoassay device when a cartridge (107) is placed in the holster (301), an electromechanical motor system (106) configured to move the holster (301) in a vertical direction with respect to the optical system (121) so that the optical system (121) can interrogate different regions of the vertically oriented immunoassay device when a cartridge (107) is placed in the holster (301), and one or more digital processors (104a, 104b) and associated electronics configured to receive data from and control the optical system (121) and to control the electromechanical motor system (106).
A reader system for analyzing one or more analytes in a fluid sample, comprising:
The reader system of any one of the preceding claims, wherein the casing further comprises a display screen, a data entry device, or a combination thereof.
The reader system of any one of the preceding claims, wherein the light source is a surface mounted light emitting diode.
The reader system of any one of the preceding claims, wherein the collection lens is configured to collect emitted light from an entire excited region.
The reader system of any one of the preceding claims, wherein the excitation optics further comprises an optical excitation filter.
The reader system of any one of the preceding claims, wherein the collection optics further comprises an optical collection filter.
The reader system of any one of the preceding claims, wherein the excitation optics further comprises a plate with one or more optical apertures.
The reader system of any one of the preceding claims, wherein a cartridge comprising a vertically oriented immunoassay device is located within the holster.
The reader system of any one of the preceding claims, wherein the vertically oriented immunoassay device comprises multiple immunoassay channels and the excitation optics comprises multiple light sources, each with different central wavelengths.
The reader system of any one of the preceding claims, wherein the optical collection plane of the collection optics and the optical excitation plane of the excitation optics form an angle that is offset from normal.
The reader system of any one of the preceding claims, further comprising one or more quality controls checks that are actualised in software on the one or more digital processors.
The reader system of any one of the preceding claims, further comprising at least one sensor for recognizing cartridge insertion or removal.
The reader system of any one of the preceding claims, further comprising a barcode reading system.
The reader system of any one of the preceding claims, wherein the electromechanical motor system comprises an encoder which is used to detect and report a relative position of the holster.
The reader system of any one of the preceding claims, wherein the reader system comprises travel sensors that are used to detect and report a relative position of the holster.
The reader system of any one of the preceding claims, further comprising a printer.
The reader system of any one of the preceding claims, further comprising components and protocols for external wireless access, such as by Wi-Fi, ANT or Bluetooth.
The reader system of any one of the preceding claims, further comprising components and protocols for wired connectivity, such as by serial, USB or Ethernet cable.
The reader system of any one of the preceding claims, further comprising alignment features within the holster for ensuring alignment of the cartridge.
