A device for giving injections has a housing having a lower surface and an upper surface with a passage through the housing extending between the upper and lower surfaces. A DC motor with an eccentric fixed to the motor is boated inside the housing to vibrate the housing. At least one tubular insert is located in the passage through the housing and is fixed to the housing. A syringe receiver is located inside and fixed to the at least one tubular insert. The syringe receiver contains a foam insert defining a space for receiving a syringe. The foam insert is a polyurethane foam characterized by an indentation force deflection of about 25% at 127 N and about 65% at 256 N. The foam insert isolates a syringe from the vibrating of the housing.
