- a receptacle for receiving a fluid substance;
- a pump in fluid communication with said receptacle for delivering said fluid substance in a spray form to an ear;
- a delivery tube for delivering said fluid substance from said pump to said ear, said delivery tube having a distal end and a proximal end, said proximal end secured to said pump;
- and
- a fluid nozzle secured to said distal end of said delivery tube, said fluid nozzle having a first portion having a first diameter dimensioned to allow said nozzle to fit easily and snugly within the concha of said ear, and a second portion having a second diameter dimensioned to prevent said first portion of said fluid nozzle from entering the canal of said ear;
- whereby when said nozzle is introduced into said ear, said fluid nozzle is prevented from damaging the external organs of said ear.
