InControl Medical, located in Wisconsin, is a medial equipment company offering solutions for female urinary incontinence, a common problem among women, particularly after childbirth. At least 20% of the female population in the United States experiences this problem. Previous offerings to solve this health problem were uncomfortable, yielding poor results that often lead to invasive surgery to correct the pelvic floor.
In response to this problem, InControl Medical created InTone, which combines electrical muscle stimulation and biofeedback to create a non-invasive home-use solution offering more comfort, better tracking, and thus improved results for patients. The patented probe, shown below, contains a small pressure sensor that measures the change in pressure inside the probe when the muscle contracts against it. This data is tracked in the handheld control unit that acts as a portable therapist, guiding the patient with visual and audible instructions to ensure exercises are done correctly. Precise gains in pelvic floor muscle strength are documented in one one-hundredth of a pound per square inch. Each session is date stamped and weekly averages are calculated to compare against previous weeks, thus allowing health care providers to follow the patient's progress.
About the pressure sensor
When selecting a pressure sensor, InControl turned to Servoflo to assist in finding a solution. After evaluating their application requirements, Servoflo suggested trying the SLP33A Pressure Sensor Series, a high performing gauge pressure sensor with a 0-2 psi range and a linear 0.5 to 4.5 volt output. Because the temperature range in the application is narrow, InControl is able to optimize the output resolution and accuracy to provide data to one one-hundredth of a pound per square inch. This pressure sensor also accepts a low power supply of 2.2V to 3.3V and a small size of 10 mm X 8.6 mm, making it a perfect fit for portable medical applications. The pressure sensor is available as a 6 pin dual-in-line package or surface-mount. The high performance combined with low cost made it an ideal choice for InControl Medical.
