History

Lancets have been used since the 15th century. The name "lancet" is derived from the lances knights once carried. When referring to a lancet today, most people think of the modern lancet device. This device was invented by Urs A. Ramel in Sunnyvale, California, and was patented on July 30, 1996.

How to Use

Needles for the lancet device are covered with a cap that twists off. Some lancet devices hold multiple needles. Load needles according to manufacturer instructions. Wash your hands in warm soapy water. Warm water will help increase blood flow. Be sure to dry your hands completely. You can also let your hand hang down at your side to increase blood flow. Gently massage your finger, rubbing toward the tip, then squeeze three times. Hold the lancet device against the side of the finger, as it is less painful than the middle part of your finger. Depress the trigger and massage a drop of blood out onto your test strip.

Types

There are several types of lancet devices on the market today. Some hold multiple needles and some only one at a time. Some lancet devices allow you to adjust the depth of the needle. If you have better circulation, you can use a shallow depth, which is usually less painful.

Purchase

Lancet devices can be purchased without a prescription. Lancets can be ordered online or picked up at your local drug store.

Disposal

Sharps containers are ideal for disposing of lancet needles, but they can be expensive. Other disposal options are an old coffee can with a tight light or old laundry-detergent bottles. Dispose of the container according to your local waste-disposal rules.
