Consists of a sensor electrode (implanted or disposable) that measures glucose concentration in the interstitial fluid, and a receiver device where the measurements are sent through by a transmitter to be displayed.
To automatically measure glucose at regular intervals (e.g. every 5–15 minutes). Measurements can be displayed to the patient continuously, or after scanning the device. An alarm may sound to notify of measured or predicted hyper- or hypoglycemia.[7][8]
A portable drug-delivery device, comprising an insulin container (prefilled for disposable pens, or refillable with cartridges); a dialing system to select the dose (in increments of 0.5 or 1 Unit); and a button which delivers the drug when pressed; disposable needles are attached prior to each use.
To administrate insulin under the skin.[10]Smart insulin pens have been developed that wirelessly connect to mobile apps, to log doses and variously facilitate therapy.[11]
A small, portable pump, which delivers insulin from a container, via a plastic tubule and a cannula, under the skin.
To continuously infuse fast-acting insulin that covers the basal insulin needs of the body, and also bolus doses as needed for meals or high glucose values. Pumps can be augmented with continuous glucose monitors, to better control insulin administration.[12]
A portable instrument that takes single-use needles or lancets. It contains a spring, which is cocked and released by buttons. Once loaded, the device is held against a fingertip, and upon release the spring drives the lancet to prick the skin rapidly, and thereby less painfully. It also includes a controlling system to alter the penetration depth.
A system of mirrors or prisms that projects a lateral view of the eye against a ruler that measures the distance from the lateral canthus to the anterior surface of the cornea
