Abstract
The devices, systems, and methods disclosed herein provide sample verification capabilities in a single device or system. Devices are disclosed herein. Systems including these devices are also provided. These devices and systems may be configured for verifying sample integrity prior to a subject leaving a sample collection site so that any further samples or other corrective action can occur without having to make a separate visit.
Claims17
A sample verification device for use with a sample container holding no more than 250 μL and containing at least one sample, the device comprising:
- an enclosure with a lid that is openable to allow for inserting said sample container, said enclosure providing a light controlled housing when the lid is closed and houses the following:
- at least one image capture device;
- at least another image capture device;
- a sample container support comprising a spacer with a cut-out for holding the sample container to be imaged along a first axis of said sample container by said at least one image capture device while also being imaged along a second axis by the at least another image capture device, wherein the second axis is orthogonal to the first axis;
- at least one backlight;
- wherein said at least one image capture device is aligned to collect visual information about at least one characteristic of the sample and using image processing to detect if the sample fails to meet one or more sample collection criteria, wherein the sample container support is configured to position the sample container between said at least one backlight and the at least one image capture device, wherein the sample container is capped with an opaque container cap while the sample container is being imaged by said image capture device.
A sample verification device for use with a sample container containing at least one sample, the device comprising:
- an enclosure with a lid that is openable to allow for inserting said sample container, said enclosure providing a light tight enclosure when the lid is closed and houses the following:
- at least one image capture device;
- a sample container support;
- at least one backlight;
- wherein said at least one image capture device is aligned to collect visual information about at least one characteristic of the sample and using image processing to detect if the sample fails to meet one or more sample collection criteria, wherein the sample container support is configured to position the sample container between said at least one backlight and the at least one image capture device;
- a multi-angle information capture system comprising using the at least one image capture device and optical element to simultaneously image a first surface of the sample container and a second surface of the sample container, wherein said second surface is orthogonal to the first surface, wherein the sample container is capped with a non-transparent container cap while the sample container is being imaged by said image capture device.
A method of performing sample verification on a sample in a sample container, the method comprising:
- placing the sample container in an enclosure with a lid that is openable to allow for inserting said sample container, said enclosure containing a sample capture device and provides a light tight enclosure when the lid is closed;
- capturing information about at least one characteristic of the sample along a first axis of the sample container;
- capturing at least one sample identifier associated with the sample along a second axis of said sample container, wherein said second axis is orthogonal to the first axis, wherein said capturing occurs when the sample container is capped with a non-transparent container cap;
- keeping a subject at the sample collection facility until sample verification is completed;
- communicating an alert to a user if the sample fails to meet at least one sample collection criteria, whereby a remedial action is taken before the subject departs from the sample collection facility;
- wherein said capturing information comprises placing a sample vessel with the sample between a back light and an image capture device.
