DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0048] Disclosed is a diagnostic test reader and related methods or systems. In one embodiment, a smartphone, including diagnostic software and a camera, may be docked onto the reader so that the camera of the phone is coupled to a diffuser for imaging test strips or other test cartridges provided to the reader. Preferably, the diagnostic software is configured to interpret an image of the strip and provide diagnostic feedback via the interface of the phone. Light for producing the image may be from the flash of the smartphone camera or a light source inside the reader. The more specific details of the disclosed reader are described in connection with the figures.
[0049] FIG. 1 is a perspective view of a smartphone test reader 1000. FIGS. 2 through 7 are respectively front, back, right-side, left-side, top, and bottom views of the smart phone test reader 1000 of FIG. 1. Together, these figures illustrate the preferred external structures of the depicted smartphone test reader 1000. As shown, the reader 1000 is generally in the form of an easel that is defined by two components: a top panel 1100 and a bottom panel 1200. The top 1100 and bottom 1200 panel mate to form an upright in the back (see FIG. 3) and an angled support surface or docking station 1110 in the front (see FIG. 2) for a smartphone (not shown). It should be noted that hereinafter the terms upright or upright rear portion designate the back portion 1500 of the reader 1000, shown in FIGS. 1 and 3, i.e., the portion 1500 that supports the docking station 1110 in an angled orientation. The upright rear portion of the reader 1000 is configured to receive a test cartridge 3000 or test strip via a port 1120. As shown, the docking station has a diffuser aperture 1111 and a lens aperture 1112.
[0050] FIG. 8 is an environmental view of the reader 1000. As discussed in greater detail below, the docking station 1110 is configured to receive a smartphone 2000 with a light source and camera lens that that are mated or coupled with the diffuser aperture 1111 and lens aperture 1112.
[0051] FIG. 9 is an exploded view of the reader 1000 of FIGS. 1 through 8. FIGS. 9A and 9B are left and right hemispheres of the reader 1000 with the inside of the reader exposed. The figures illustrate the mating of the upper and lower panels 1100, 1200 and the internal structural features of the reader 1000. As shown in FIG. 9, the upper panel 1100 receives the bottom panel (see FIGS. 9A and 9B) and accomplishes a snap fit or friction fit. As shown in FIGS. 9, 9A, and 9B, the lower panel 1200 features a deck or platform 1121 that is aligned with the external port 1120 for receiving, supporting and presenting a cartridge 3000 to the diffuser and lense ports 1111, 1112 of the upper panel 1100. Referring to FIG. 9A, the deck 1121 features a sensor switch 1123 that, as discussed further below, wirelessly alerts a smartphone (not shown) placed in the docking station 1110 that a cartridge 3000 has been placed in the deck 1121. Referring to FIG. 9B, the upper panel 1100 features a diffuser holder 1113 for holding a diffuser (not shown) between a cartridge 3000 and a light source of a smartphone (not shown) installed in the docking station 1110.
[0052] FIG. 10 is a perspective view of an assembly of a unified smartphone 2000 and a smartphone test reader 1000. FIG. 11 is a horizontal cross section of the assembly of FIG. 10. FIG. 12 is a longitudinal cross section of the assembly of FIG. 10. As shown in FIG. 10, (a) a smartphone 2000 may be positioned in the docking station 1110 of the reader's 1000 upper panel 1100 and (b) a cartridge may be provided to the port 1120 in the upright back end of the reader 1000.
[0053] As shown in FIGS. 11 and 12, a smart phone 2000 may be positioned in the docking station 1100 so that the flash 2100 of the smartphone 2000 is coupled to the diffuser aperture 1111 and the smartphone's 2000 camera lens 2200 is coupled to the lens aperture 1112. Suitably, the diffuser holder 1113 may be provided with a diffuser 4000. In one embodiment, the test cartridge 3000 is provided through the port 1120 so that the cartridge 3000 rests in the deck 1121 and triggers the switch 1123 for alerting the smartphone of its presence. In one embodiment, (a) an additional light source (e.g., a fluorescent bulb) 1300, (b) an additional detection system (e.g., a camera) 1400, and (c) a power source (e.g. rechargeable battery) 1500 are provided to within the internal cavity of the reader 1000. Suitably, the deck 1121 presents the cartridge 3000 to the cameras 1500 or 2200 and light sources 1400 or 2100 for imaging.
[0054] FIG. 11 through 12 further illustrate a typical mode of operation for the reader 1000. Initially a smart phone 2000 may be provided to the docking station 1110 and a cartridge 3000 provided to the port 1200. In a preferred embodiment, the reader 1000 features wireless communication and sensor hardware (not shown) that senses the docking of the phone 2000 and prompts initialization of the light source 2100 of the smartphone 2000 or the internal light source 1400. A sample (shown as drops) may be provided to the test strip 3000 as shown. In one embodiment, the reader 1000 senses the presence of the cartridge 3000 via the sensor switch 1123 and wirelessly commands the phone 2000 to initiate its vibrating function so that the reaction or other processes associated with testing the sample can be facilitated by the motions of the vibrating smartphone. In lateral flow test strips, the vibration function of the smartphone may be used to facilitate reactions or otherwise make the test strip more sensitive. Finally, the interface of the smartphone 2000 may be interacted with to assess the test results. In a preferred embodiment, the software and smartphone may feature audible commands for walking a user through the test reading procedures.
[0055] FIGS. 13 through 28 illustrate various screenshots of a software applications that may be installed on a smartphone for reading test results. FIG. 13 illustrates a home screen for the software app. As shown, the home screen features at least three buttons: a new test button; a history button; and a support button. Interacting with the new test button will result in the Select Test screenshot shown in FIG. 14. Referring to that figure, a list of possible tests are presented for having the results read by the reader 1000 of the earlier figures. In a preferred embodiment, a Fertility Tests option may be selected so that a user is given a choice to either (a) scan a QR code or a test to see if the test strip or cartridge is authorized for use in the reader or (b) get a guide for administering the test. IF scanning a QR code is selected, then the software transitions to the Authentication screen shot of FIG. 18. IF the get guide options are selected, THEN the screen shots of FIGS. 22 through 24 (guides for administering the test) are presented in series AND the software transitions to the Authentication screen shot of FIG. 18. IF the test strip or cartridge is authenticated by the software and QR scan function of the smartphone, T the software presents the imaging screen shot of FIG. 19, ELSE an invalid screenshot FIG. 21 is presented. Referring to the screenshot of FIG. 19, images of the test cartridge 3000 of the earlier figures may be captured, analyzed and presented in the results screenshot (FIG. 20). In the case of a fertility test, the image is analyzed for two bars (positive), a left bar (negative), or a right or no bars (inconclusive).
[0056] Returning to the home screen of FIG. 13, IF the history command button is selected, THEN a password entry screen (FIG. 15) is presented to the user wherein IF a password is successfully entered, THEN a history of tests is presented (FIG. 25). Still referring to FIG. 13, if the documentation command is selected, THEN a user is presented with options (e.g FIG. 14) to view the documentation of one of the various tests. For example, if a fertility test is selected, a user can choose, via the screenshot of FIG. 26, to view FAQ (FIG. 27), safety information (FIG. 28) or a guide (FIGS. 22 through 24). In one embodiment, the software further features functionality for calendaring the results of the test and, in the case of fertility, periods of time where the user is fertile.
