Study of a Device to Relieve Mosquito Bite Itching.
January 13, 2009 updated by: Ecobrands, Ltd.
Relief From Itching of Mosquito Bites Clinical Study Protocol.
The purpose of this study is to determine whether over-the-counter (OTC) use of the ZapperClick device employing the piezo-electricity principle is effective in reducing itching associated with mosquito bites.
Study Overview
Detailed Description
The ZapperClick is a therapeutic device that employs the piezo-electricity principle to soothe itching and ease the swelling from mosquito and horsefly bites as well as jellyfish and nettle stings.
It accomplishes this by discharging 13KV at 0.7mA for 10 microseconds over the area of the bite or sting each time it is activated.
In this clinical study, only the indication of reducing itching from mosquito bites will be evaluated.
The theory behind the device's effectiveness is that multiple high voltage, low current electrical discharges over a bug bite or sting generates warmth over the immediate area of the bite or sting which inhibits the histamine release, thus relieving the symptoms of itching and swelling arising from the bite or sting.
The device is a quick, simple and painless means of reducing the annoying symptoms of mosquito bites.
