Abstract
A probe cover assembly for covering and protecting the elongated probe of a tympanic thermometer. The probe cover includes an inner member, an outer member, and an intermediate transparent membrane. The inner member is mounted around the probe and includes an inner window in alignment with a distal opening of the probe and an inner flange having a projection. The outer member, closely mounted on the outer circumference of the inner member, includes an outer window in alignment with the inner window of the inner member, an outer flange, and a barb having a grip portion for biasing the inner flange of the inner member to push the projection against the outer flange of the outer member when the probe cover is in an assembled state. The intermediate transparent membrane, sandwiched between the outer member and the inner member, is gripped by the projection of the inner member and the outer flange of the outer member and is tightly stretched to cover the inner window of the inner member.
