Abstract
A protective cap (2) for a temperature measurement probe (30) of an infrared radiation thermometer (1) that can be introduced into a body cavity (31). The protective cap (2) includes a base body (12) shaped to fit the body cavity (31) and having a window (15) transparent to infrared radiation. The base body (12) is provided with additional structures (13; 18, 20) at least in parts to improve heat insulation between the temperature measurement probe (30) and the body cavity (31). This heat insulation of the temperature measurement probe (30) prevents measurement errors by the infrared radiation thermometer (1).
Claims8
A disposable probe cover for a tympanic thermometer of the type having a radiant energy sensing structure for sensing at least one wavelength of radiant energy emitted by the eardrum, the probe cover having an insertion end for being inserted into an ear canal communicating with the ear drum and another end which remains outside of the ear canal so as to seal the ear canal, at least the probe cover insertion end comprising a deformable foam body defining a passage terminating in an opening, the passage accepting at least a part of the radiant energy sensing structure and communicating the radiant energy sensing structure with the opening, the probe cover further comprising a barrier that substantially occludes the passage, the barrier preventing ear canal contaminants from entering the opening while substantially allowing the radiant energy to pass therethrough and impinge upon the radiant energy sensing structure.
In combination:
- a tympanic thermometer probe;
- and
- a hollow compressible foam body stretched over the probe to provide a friction fit that securely retains the foam body on the probe's outer surface, the foam body providing heat isolation for the probe and increasing comfort when, in use, the probe and foam body are together inserted into a human ear canal.
