Abstract
A tip element that is capable of being removably attached to an infrared thermometer and includes an axisymetric body having a distal end and an open proximal end. A membrane is located at the distal end of the body that is formed of an infrared transparent material. At least one engagement mechanism is mounted along the proximal edge of the body that has an engagement surface that passes circumferentially about a portion of the proximal edge and which contains an integral rib that extends axially toward said distal end of said body.
Claims20
A tip element that is securable to a medical thermometer and further includes:
- a conical shaped body having a distal end and an enlarged circular open proximal end;
- a membrane located at the distal end of said body, said membrane being fabricated of a material that gathers infrared energy from its surroundings and concentrates said energy upon a target;
- at least one raised external engageable member that partially encircles the proximal end of said body having teeth, the teeth engaging a co-acting locking mechanism of the medical thermometer;
- said at least one engageable member having a raised rib that is integral therewith and at least partially extends along a direction of said body between the proximal end and the distal end such that said rib is finger engageable for rotating said body about its axis.
A tip element that is securable to a medical thermometer and further includes:
- a conical shaped body having a distal end and an enlarged circular open proximal end;
- a membrane located at the distal end of said body, said membrane being fabricated of a material that gathers infrared energy from its surroundings and concentrates said energy upon a target;
- at least one raised engageable member that partially encircles the proximal end of said body that is adapted to engage a co-acting locking mechanism of the medical thermometer;
- and
- said at least one engageable member having a raised axial extended rib that is integral therewith such that said rib is finger engageable for rotating said body about its axis,
- wherein said membrane is configured as a plurality of radiation lenses stacked in alignment along the axis of said body for focusing radiation upon a given target,
- wherein said radiation lenses have at least one curved face for concentrating radiation upon a target.
A tip element that is securable to a medical thermometer and which further includes:
- an axisymetric shaped body having a distal end and an enlarged circular shaped proximal end that is open;
- at least one raised external engageable member that partially encircles the proximal end of said body having teeth, the teeth engaging a co-acting locking mechanism of the medical thermometer;
- said at least one engageable member having a raised rib that is integral therewith and at least partially extends along a direction of said body between the proximal end and the distal end;
- and
- said body further includes a section that tapers upwardly from the distal end thereof toward the proximal end and that contains protrusions for removing cerumen from the surface of an ear contacted by said body.

- at least one raised external engageable member that partially encircles the proximal end of said body having teeth, the teeth engaging a co-acting locking mechanism of the medical thermometer;
- said at least one engageable member having a raised rib that is integral therewith and at least partially extends along a direction of said body between the proximal end and the distal end;
- said body further includes a section that tapers uniformly from said distal end of the body towards the proximal end and which contains protrusions for removing cerumen from the surface of an ear that is contacted by said body;
- and
- a membrane located at the distal end of said body, said membrane being fabricated of a material that gathers infrared energy from its surroundings and concentrated the energy upon a target.
The tip element of clam 16, wherein said membrane is fabricated of a polyethylene.
