<p>A sensor probe cover (20) is constituted by two sheets of transparent film (21) and (22) each being of a generally square shape and a ring (23) having a hole (23a) suitable for fitting over a sensor probe (12). A hole (21a) is formed in the center of the first film (21) and a ring (23) is welded to the peripheral edge of this hole (21a) in the inner surface of the first film (21). The ring (23) is formed of a material harder than that of the film. The first film (21) and the second film (22) are hot-welded to each other at four corners thereof. The positions of hot welding are designated by reference numerals (20a). The second film (22) is formed of a material which can transmit infrared rays therethrough when it is used for a cover of a probe in an infrared ray clinical thermometer. When the forward end of the probe (12) is pushed into the ring (23) from above the second film (22), the second film (22) covers the probe (12) while the second film (22) is turned over. When the ring (23) is fitted into an annular groove (12a) of the probe (12), the mounting of the cover is completed.</p> |
