The present invention relates to an improved delivery system for a dental treatment solution. More particularly, the apparatus disclosed includes a housing defining a well, a reservoir container for the dental treatment solution, and a pump for delivery of the solution to a hand piece. The pump includes an electrically energizable prime mover such as a motor or solenoid, a heater, and a control for the overall system. The control for the system provides a timing arrangement which is actuated upon placement of the reservoir container within the housing well, and which disables the system upon completion of the timing cycle. This feature, coupled with the employment of a visual signal, provides a dental professional with an indication of the strength or useful life of the dental treatment solution. Also disclosed are novel constructions for the pump and the heater, along with a novel design for the reservoir container.
Appartus for delivery of a dental treatment solution or the like, to a patient said apparatus comprising:
Apparatus for delivery of a dental treatment solution or the like to a patient wherein said solution has a predetermined usable life cycle after initial formulation, said apparatus comprising:
Apparatus for delivery of a dental treatment solution or the like, said apparatus comprising a housing including wall structure defining a well, a reservoir container for the dental treatment solution disposable in said well, said reservoir container including a lid pivotally mounted thereto, pivot means defining a pivot point for the lid which is disposed sufficiently below the upper level of said reservoir container such that when said container is positioned in said well, the wall structure of said well inhibits opening pivotal movement of said lid.
Apparatus for delivery of a dental treatment solution or the like, said apparatus comprising a housing including wall structure which defines a well portion, a reservoir container for the dental treatment solution disposable in said well portion, said well portion including an elongate opening extending to the front of said housing, said reservoir container including a transparent extension portion received in said elongate well opening and viewable from the exterior of said housing to thereby provide a visual indication of the level of dental treatment solution in said reservoir container, and further including a relieved portion adjacent and beneath said elongate housing opening to provide a finger grip, whereby said reservoir may be gripped by said extension portion and removed.
Apparatus for delivery of a dental treatment solution or the like, said apparatus comprising, a housing having pumping means and control means for said pumping means, and including wall structure defining a well portion, a reservoir container for the dental treatment solution disposable in said well portion, said housing well portion including a bottom wall, and a series of drain holes formed in said bottom wall to alleviate any spillage during disposition of said reservoir container in said well portion, said reservoir container including a bottom well structure and valve means carried by said bottom wall structure, and further incuding at least three leg members extending from the bottom wall portion thereof and being of sufficient length to extend past said valve means, said leg members being receivable in the drain holes provided in the bottom of said well portion, said housing including conduit means leading to said pump means and means for engaging and opening said valve means upon disposition of said reservoir container into said well portion.
A reservoir container for use with apparatus for delivery of a dental treatment solution or the like, said reservoir container adapted to be disposed within a well portion and operatively connected to pumping means of said apparatus, said reservoir container including a body portion having an upper open rim, a cover member, means pivotally connecting the cover member to the body portion, said means comprising a pair of pivot pins extending from the opposite sidewalls of said body portion and disposed below the level of the upper rim of said body portion, said cover including a pair of flange members disposed on opposite sides thereof, and each said flange member having elongate slot means formed therein for reception of said pivot pin on the body portion, and detent means on said cover for engaging the rim such that when said detent means are so engaged a first open position is defined for said cover member, the pivot pins engaged in an upper region of said elongate slots, and said cover being movable to a second, fully open position upon disengagement of said detent means from said rim and upon disposition of said pivot pins in a lower region of said slots.
Apparatus for delivery of a dental treatment solution or the like, said apparatus comprising:
