Claim 0:
1. A shower head system for dispensing a therapeutic substance, the shower head system comprising:
a shower head with proximal and distal ends and a primary fluid passageway extending between the proximal and distal ends for conducting a flow of water from the distal end and outward from the proximal end;
a cartridge socket, the cartridge socket having a socket opening through the proximal end, a socket end wall spaced from the socket opening in a direction toward the distal end, and a socket sidewall extending between the socket opening and the socket end wall;
a cartridge removably inserted into the cartridge socket and releasably retained therein, the cartridge having a dispensing end that is spaced from the socket end wall when fully inserted into the cartridge socket thereby providing a diffusion gap between the dispensing end and the socket end wall, the cartridge having a substance containing space;
a pin extending into the cartridge socket from the socket end wall, the pin extending through the cartridge dispensing end when the cartridge is fully inserted into the cartridge socket, thereby opening the substance containing space to the diffusion gap; and
a diffusion passageway extending through the socket sidewall at a position on the socket sidewall that is located along the diffusion gap and the diffusion passageway fluidically connecting the diffusion gap and the primary fluid passageway;
an impingement plate, having an impingement plate collar;
a hub, the hub attached to the impingement plate and having a hub end wall that at least partially provides for the socket end wall;
a sleeve having a first sleeve end, a second sleeve end, a sleeve bore extending between the first and second sleeve ends;
the impingement plate collar being received in the sleeve bore and the sleeve being rotatable about a rotation axis extending between the proximal and distal ends and relative to the impingement plate collar;
the hub being received in the sleeve bore;
an interior surface of the sleeve bore at least partially providing the socket sidewall; and
wherein rotating the sidewall by rotation of the sleeve, in a first direction about the rotation axis selectively closes the diffusion passageway and rotating the sidewall by rotation of the sleeve in a second direction about the rotation axis selectively opens the diffusion passageway.
