Abstract
Abstract An applicator assembly and method for self-testing a body cavity to determine the condition therein is disclosed. The assembly includes a reusable, applicator body (10), formed with a probe (15) having a tip end (16) formed and positioned for movement between a retracted position and an extended position. Removably mounted thereon is a flexible sheath (25), which carries a sensor (30) proximate the end of the sheath. Upon movement of the probe to the retracted position, the sensor and sheath are drawn into the applicator body to protect the sensor from contamination before testing. The assembly is then inserted into the cavity, the probe is extended for testing and retracted for removal of the assembly from the cavity. To observe the test results, the probe is again extended. The sheath is removable and a new sheath can be mounted over the applicator body for repeated testing. A method of self-testing, using the assembly of the present invention is also provided.
