A feature study of innovative high-speed lancing device and safety lancet

Abstract

The study developed two models of an innovative high-speed lancing device and safety lancet, where the specially designed structure causes high-speed motion of the lancet, resulting in only one puncture of the skin. The two experimental models and other lancing devices sold on market were compared in order to: (1) measure the forces of lancets piercing animal skin by a load cell; (2) observe the wound areas caused by lancing devices under a microscope. The experimental results showed that, after using this innovative high-speed lancing device, the maximum force of a lancet piercing skin is only 1/3 of the force of conventional lancing devices, and the duration of the former under the skin is 1/6 of the latter. In addition, the wound area caused by the innovative lancing device is 20 % smaller than those of the conventional lancing devices. Usage of this innovative high-speed safety lancet shows that its maximum skin-piercing force is only 2/3 of conventional safety lancets, its duration under the skin is 1/4 of conventional safety lancets, and the wound area is 12 % smaller. In conclusion, both the innovative high-speed lancing device and safety lancet are proved effective in alleviating pain for diabetics and shortening the recovering time for wounds, thus, providing a more comfortable process for the self-monitoring of blood glucose.

Lancing Drug Reservoirs into Subcutaneous Fat to Combat Obesity and Associated Metabolic Diseases

“…The mark left by ML is similar to those (~0.15 mm 2 ) created by stainless-steel needles of 32-gauge size. [22] During 1 week of observation period, there were no significant differences in body weight and food intake between the control and tested groups (Figure 3D and E). In addition, no sign of pain was observed from the mice administrated with ML, as assessed by the grimace scoring (Figure 3F).…”

“…These values are comparable to those achieved by the lancet lancing devices used by diabetes patients at home for blood sampling. [22] The lancing speed, thus the skin penetration depth, can be adjusted by varying the spring compression.…”
