Application: Pneumatically measures uterine contractions during pregnancy, labor and delivery.

Tocodynamometer (“TOCO”) – Pneumatic TOCO (“pTOCO”)

Suggested Uses

Improved replacement for the current standard for measuring uterine contractions during labor is a “guard-ring” style method that was developed by Smyth et al in the 1950’s.

Advantages

a smaller, lighter, low cost, self-adjusting, non-invasive, disposable and an external pneumatic uterine pressure monitor device.

Detailed Description

External Uterine Pressure Monitors – Pneumatic TOCO: clinical prototypes tested and support its utility (10-16)

Tocodynamometer (“TOCO”) – Pneumatic TOCO (“pTOCO”)

Application: Pneumatically measures uterine contractions during pregnancy, labor and delivery.

On average there are over four (4) million births each year in the U.S.A. alone. By adding just the industrialized countries where this device could be patented would more than triple that number of annual births.

The current standard for measuring uterine contractions during labor is a “guard-ring” style method that was developed by Smyth et al in the 1950’s. This method is either an external strain-gauge device and/or an intrauterine pressure catheter.

University ObGyn researchers have engineered a novel working prototype for monitoring external contraction profiles during pregnancy, labor and delivery. This pTOCO device is a smaller, lighter, low cost, self-adjusting, non-invasive, disposable and an external pneumatic uterine pressure monitor. The pTOCO is a significantly improved alternative to the current standard “guard-ring” TOCO that exceeds the operational capabilities of the “guard-ring” device.

The competing technology in today’s market place is not disposable and is very expensive. Additionally, the current standard is based on mechanical measurements of pressure, whereas the subject of the current invention called the pTOCO employs pneumatic measurements of pressure.

The pTOCO device has been thoroughly tested in the clinical setting is currently functional and fully operational. More importantly, this invention is compatible with all available fetal heart rate monitors.

Currently, two designs have been disclosed: (i) a pressure transducer version, and (ii) an air volume differential version.
