Dental water and air purification equipment

Disinfectant apparatus comprising:

• a) a housing including a manifold cavity having an inlet bore to said cavity, an end cap including a discharge port, and means for securing said end cap to said housing;
• b) a cartridge mounted within said housing having a tubular body containing a plurality of spacers arranged within a bore to separate first and second treatment media, wherein said first treatment media comprises a disinfectant, and wherein said second treatment media comprises a halogen scavenger which removes residuals of said disinfectant media;
• and
• c) means for sealing and retaining said housing and cartridge to a nozzle piece of a dental hand tool in flow communication to a water conveying conduit, whereby purified water is discharged from the discharge port.

A dental hand tool comprising:

• a) a handle including a plurality of flow bores for conveying air and water, means for coupling said flow bores to mating air and water supply conduits, and including a manifold cavity in flow communication with one of said flow bores;
• b) a cartridge means having inlet and outlet ports for containing a disinfectant media;
• and
• c) means for non-permanently sealing said cartridge means within the manifold cavity in flow communication with the water conveying one of said flow bores to convey water through said inlet and outlet ports, whereby water is directed through said cartridge means and purified prior to discharge from said hand tool.

Disinfectant apparatus comprising:

• a) an adaptor housing including a plurality of flow bores, coupler means for coupling said flow bores to mating conduits of a hand tool at an outlet end of said housing and to air and water supply conduits at an inlet end to said housing, and wherein a manifold cavity interrupts at least one of said flow bores;
• b) cartridge means having inlet and outlet ports for containing a treatment material selected from a class of materials containing a halogen disinfectant and a halogen scavenger media;
• and
• c) means for non-permanently sealing said cartridge means within the manifold cavity in flow communication with the one of said flow bores, whereby either said water and/or air is directed through said cartridge and purified prior to discharge from said hand tool.
