Urination, Micturition, Voiding Process of disposing
urine from the urinary bladder through the urethra to the outside of the body
Process is under voluntary control
Main organs involvedUrinary bladderUrethra
Urinary Bladder and Urethra Detrusor muscles
Smooth muscles of the bladder Innervated by sympathetic and
parasympathetic nerves Internal urethral sphincter
Located at the proximal inferior end of the bladder, at the junction of the urethra with the bladder
Smooth muscle Under involuntary control
External urethral sphincter Located at the distal inferior end of the
bladder Skeletal muscle Under voluntary control
To void Detrusor muscles contract Relaxation of the sphincters Voluntary contraction of the abdominal
muscles
What is Urinary Incontinence? Urge Incontinence
Involuntary loss of urine associated with abrupt and strong desire to void
Stress Incontinence Involuntary loss of urine during coughing,
sneezing, laughing, etc
Overflow Incontinence Involuntary loss of urine associated with
over distension of bladder
Functional Incontinence No recognition of need to void, inability
to make it to the toilet in time
Causes Neurological disorders
Parkinson’s, Multiple Sclerosis, Alzheimer‘sStroke, brain tumor, spinal injury
Hormone imbalancesMenopause
Prostate cancer Loss of muscle tone
Childbirth, old age
Prevalence 13 million people in the U.S. 10-35% of adults 50% of the 1.5 million
residents in nursing homes leading cause of admission to
a nursing home may lead to pressure sores
and ulcers, possibly resulting in secondary infections

Specifications Desired Comply with industry standards for
urological medical devices Be able to remain indwelling for 30 days Easily operated by patient with disabilities Allow emptying of the bladder when
desired Prevent urine flow when not desired Provide an indication of the status of the
bladder.
AMS 800
artificial urinary sphincter
implantable, fluid-filled, solid silicone elastomer
AMS 800 Testing Determined the force required to compress
the pump of the AMS 800 6.3 mm was too much for the electromagnets.
Decided to create a new design based off the AMS 800 using electromagnets.
Interstim Typically used to treat
urge incontinence Inserted into the sacral
nerves to activate or inhibit muscles and organs that contribute to urinary control -- the bladder, sphincter and pelvic floor muscles.
Cost of device: $8,800.00
We are using it as a power source
Design A Electromagnets will be
activated causing the device to clamp the urethra closed.
Second set of electromagnets will release the clamp.
Design B Utilize a servo and
push rod to collapse urethra
Powered by 4.8V
Provides sufficient torque to drive a sphincter mechanism
Methods Adapt an actuator to activate
the device
Actuator will receive a signal through a micro RC receiver
RC receiver is controlled externally to allow simple evacuation of bladder
Dimensions : .85 x 1.25 x .5“
Status Corresponding with Konica Minolta ,
Systemax and Hitachi about circuitry for our device
