A pelvic floor contraction detection system and method to evaluate pelvic floor muscle (PFM) exercise performed by a user are disclosed. The contraction detection system comprises a probe adapted to position within a pelvic cavity of the user, a data processing module, and a user interface. The probe comprises two or more sections. Each section is filled with a group of electronic sensors. The first and second sections are seated in contact with tissues of the pelvic cavity. The first and second groups of sensors are configured to detect pressure applied by the internal vaginal surface on the surface of the first and second sections of the probe respectively. The data processing module is in communication with the first and second groups of sensors and configured to calculate a number that is interpreted as the “quality of the contraction”. The data processing module determines the incorrect pelvic floor muscle contraction and notifies the user via a user interface.

A pelvic floor pain relief device for use by humans. The device is spherical, and comprised of three layers. The core of the device is a compact compressible spherical core, having a compressibility rating sufficient to substantially support the weight of a human sitting thereon while allowing but minimizing the deformation of the sphere under the human load. A strengthening layer, consisting of randomly wound filament material, is wound around the exterior of the compressible spherical core to further minimize the deformation of the sphere in use. Finally, an exterior protective layer retains the filament of the strengthening layer in relation to the sphere and provides a cleanable surface. The method of use of the device is also disclosed.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.

Disclosed is an extensible electrode array (102) for accurately locating a pelvic floor muscle, and its design method and an extensible pelvic floor electrode. The design method includes: (1) obtaining a three-dimensional muscle anatomy map of a pelvic floor muscle, dividing a muscle according to the three-dimensional muscle anatomy map and determining a muscle fiber trend, and for each muscle, determining a plurality of three-dimensional coordinate points for marking each muscle along the muscle fiber trend (S101); (2) after projecting all three-dimensional coordinate projects onto a two-dimensional plane unfolded in a shape of an elastic cavity (101), taking each two-dimensional coordinate point in the two-dimensional plane as a location to dispose an electrode plate (S102); (3) simulating a mechanical property of the elastic cavity (101), and determining a deformation rate of an extensible electrode wire (105) of the electrode plate when the extensible electrode wire (105) of the electrode plate is arranged along a muscle fiber direction of the pelvic floor muscle (S103); and (4) according to a design result, mounting the electrode plate and the extensible electrode wire (105) on the elastic cavity (101) to form the extensible electrode array (102) (S104). The design method enables each electrode plate to locate the pelvic floor muscle before and after expansion, thereby improving accuracy in collecting a myoelectric signal of the pelvic floor muscle.
