Anal and Vaginal Sensors

Anal Sensor and Vaginal Probe for PFX Pelvic Floor Exercisers and Peritron

Peritron and PFX Pelvic Floor Exercisers use identical anal sensor and vaginal probe. Hence, the anal sensor and vaginal probe presented on this page are compatible with the Peritron Perineometer and the PFX Pelvic Floor Exerciser with Biofeedback (anal and vaginal).

Peritron and PFX Anal Sensors and Vaginal Probes are Medical Devices that comply with stringent requirements of MDD 93/42/EEC. 

Please note that the anal sensor and vaginal probe designed for use with Peritron and PFX devices are compatible with other brands of perineometers.

*Peritron Perineometer, PFX Pelvic Floor exercises and accessories can be purchased VAT free for personal use by people suffering relevant chronic problems.

If a clinician uses the Peritron in the clinic and the patients carry on with pelvic floor exercises at home using the PFX pelvic floor exerciser, the patients can bring their own sensor or probe to the clinic for precise assessment of their progress using the clinic's Peritron.

Peritron and PFX vaginal probes and anal sensors are hygienic, biocompatible and latex free. The contact surfaces of Peritron sensors are made from seamless medical grade silicone elastomer. The thin wall of the silicone sheath transmits the pressure precisely and unaffected by temperature. There are no joins or crevices to trap contaminants. Toxicological testing has shown the sensors to be biologically inert.

Peritron / PFX probes and sensors are approved for safety and efficacy by the USA FDA and carry Class II CE Medical Devices CE mark in Europe.

Peritron vaginal probe has a long pressure-responsive area, which means that when the sensor is inserted to the recommended depth its pressure sensitive area will span the pelvic floor muscles of 95% of women. This means that, irrespective of who carried out the test, the sensor will be located correctly every time. Additionally, a Probe Sensor Collar can be used to prevent over-exertion (see below).

Caring for the Anal Sensors and Vaginal Probes

Vaginal Probes and Anal Sensors are items very personal to patients. Hence, most people prefer to have their own sensor. The modest cost of the probes and sensors makes the ‘one-sensor-per-patient’ rule a viable clinical policy. Single-user sensors require only a soap-and-water wash between uses.
