Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

A device for extracting a body fluid and testing a predetermined analyte or property of the fluid is provided. The device comprises a hollow needle having a channel linking a base end and a tip, a collection chamber having an input end in fluid communication with the channel, a testing chamber, a solution chamber and a flow control. The collection chamber comprises a capillary wick configured to transport at least a fraction of the body fluid away from the input end. The testing chamber comprises a testing unit including a reacting material configured to react to a predetermined analyte or property of the fluid and the solution chamber comprises a buffer solution. A flow control is also provided for a transfer of the buffer solution from the solution chamber to the collection chamber and a transfer of the body fluid from the collection chamber to the testing chamber.

A self-administered tester for infection may include a sample collection element for receiving fluid samples including bodily fluids. The sample collection elements may provide at least a portion of a collected sample to one or more evaluation elements. Each evaluation element may determine whether some evaluation criteria have been satisfied. Result indicators may provide visual indicators showing whether the evaluation criteria were satisfied. The self-administered tester may test for a Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection using evaluators associated with the Immunoglobulin G (IgG) antibody and the Immunoglobulin M (IgM) antibody.

A sample collection device includes a grip portion and a collection portion connected to the grip portion, wherein the collection portion includes a first surface and a capillary having a groove shape provided on the first surface and formed with openings at opposite ends thereof.

A blood sample collector can be used to collect a blood sample from a subject. The blood sample collector can be placed in a receptacle of a spectrometer to measure spectral data from the blood sample while the blood sample separates. The container may comprise a window to allow light such as infrared light to pass through the container, with the blood sample at least partially separating within the container between spectral measurements, which can provide improved accuracy of the measurements and additional information regarding the sample. The container may comprise an elongate axis and the container configured for placement in the spectrometer receptacle with the elongate axis extending toward a vertical direction in order to improve gravimetric separation of the blood sample. The spectrometer can be configured to measure the blood sample at a plurality of heights along the sample as the sample separates.

A smartphone protective cover that houses a glucose monitor, test strips, lancets, a lancet striker, a power source, and a biohazard debris receptacle is presented. According to the preferred embodiment of the invention, the protective covering is configured to include a smartphone adapted glucose monitor and also to accept a smartphone. In the preferred embodiment, the smartphone is removably placed into the protective covering with the glucose monitor connecting to a data receptacle on the smartphone. The protective cover further includes a lancet storage compartment adjacent to a lancet striker having a tension control member and striker release button, a test strip storage compartment, and a biohazard debris receptacle. The lancet storage compartment and test strip storage compartment can be re-Tillable or disposable. A battery is also located in the cover and is electrically connected to the glucose for monitor, thus enabling the monitor to be powered independently of the phone. A method of use is also provided.

In some examples, a diagnostic device includes a reusable part to receive a container of a fluid, the reusable part reusable for a plurality of diagnostic tests. The diagnostic device further includes a disposable part detachably attached to the reusable part and comprising a sample collector to collect a target sample of a living being. The diagnostic device further includes a tester comprising a fluid channel to transport the fluid to combine the fluid and the target sample to form a fluid combination, and to use the fluid combination to diagnose a condition of the target sample.
