| 摘要 |
A vibrating tourniquet is disclosed in which one or more vibrating devices are coupled within a pliable strap portion and are activated to interrupt nerve transmissions, and supply an alternative stimulus, that decreases the sensation of pain as the needle or IV are introduced through the skin and into a vein. The vibration devices are electrically coupled to a controller mechanism and the controller mechanism may be turned on or off after the tourniquet is applied to the arm. In alternative versions, the frequency and amplitude of the vibration may be selectively increased or decreased cooperatively or separately by adjusting the controller mechanism as needed.
