Abstract
A dental spray handpiece consisting of a gripping sleeve having a detachable media inlet connecting piece at one end thereof and a media discharge arrangement at its other end, media conduits extending from the media inlet connecting piece to the media discharge arrangement and discharging outwardly therefrom, thereby the media connecting piece possesses connectors for media constituted of air and water. The gripping sleeve which in its dimensions and its configuration forms a uniform basic member, is equippable as a spray handpiece with an electrical current circuit and an electrical power consumer, as well as a spray handpiece without a power consumer.

Dental spray handpiece comprising a gripping sleeve having a detachable and interchangeable media inlet connecting piece insertable at one end thereof and a media discharge arrangement at the other end thereof;
- air and water media conduits in said gripping sleeve leading from the media inlet connecting piece to the media discharge arrangement, said media connecting piece including connectors for media consisting of air and water;
- an air-shutoff valve for air being arranged in the media conduit for air, a branch line for air in said connecting piece branching off from the media conduit for air downstream of said air-shutoff valve, and said connecting piece possessing the connectors for air and water being provided with a dummy plug for sealing off said branch air line.
Dental spray handpiece comprising a gripping sleeve having a detachable and interchangeable media inlet connecting piece insertable at one end thereof and a media discharge arrangement at the other end thereof;
- air and water media conduits in said gripping sleeve leading from the media inlet connecting piece to the media discharge arrangement, said media connecting piece including connectors for media consisting of air and water;
- said media connecting piece including an electrical power consumer with an associated current circuit constituting electrical heating means for heating of the air;
- an air-shutoff valve for air being arranged in the media conduit for air, a branch line for air in said connecting piece branching off from the media conduit for air downstream of said air-shutoff valve, said branch line leading to a pressure-responsive electric switch for closing a previously interrupted current circuit communicating with the heating means in response to the imposition of a pressure force.
