Accu-chek is the bran of blood sugar-testing devices manufactured by Roche Diagnostics, largely for the diabetic market. Kits consist of an electronic monitor which measures blood-sugar via inserted one-time-use "strips" and a lancet device which fires a sharp needle marginally through the epidermis of the finger in order to allow a small amount of blood to be squeezed onto the strip in the monitor. In its advertisements, Roche claims this avoids "painful re-sticking" and for the "Multi-Clix" lancet device, 90% of patients in its tests found it to be the least painful of lancet devices.
