Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Nursing Assessment of the Genitourinary System II: Inspection and Palpation01:26

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...
Nursing Assessment of the Genitourinary System III: Percussion and Auscultation01:22

Nursing Assessment of the Genitourinary System III: Percussion and Auscultation

The genitourinary system maintains the body's fluid balance, waste excretion, and overall homeostasis. Proper assessment is essential for early detection of disorders, with percussion and auscultation integral to this evaluation. These methods help identify signs of kidney or bladder issues and provide important diagnostic clues.Percussion for Kidney TendernessPercussion is used to assess tenderness and detect kidney and bladder abnormalities. A common method for determining kidney tenderness...
The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...
Urodynamic Studies: Uroflowmetry01:19

Urodynamic Studies: Uroflowmetry

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
Vibrating Concrete01:19

Vibrating Concrete

Mechanical vibrators are instrumental in compacting newly poured concrete within formwork and around reinforcements. This process is essential to eliminate trapped air pockets and establish a dense concrete mass. One widely used method is vibrating by internal vibrators, often referred to as a poker vibrator or immersion vibrator. It is rapidly inserted through the full depth of the freshly laid concrete and slightly extends into the layer below it (which remains in a plastic state). Consistent...

Area of Science:

  • Biomedical Engineering
  • Urology
  • Wearable Technology

Background:

  • Urinary incontinence affects many individuals, necessitating the use of continence pads.
  • Current pad systems lack real-time monitoring for leakage, potentially leading to discomfort and skin issues.

Purpose of the Study:

  • To develop and describe a novel sensor system for monitoring urine leakage from continence pads.
  • To provide an early warning system for pad failure to users.

Main Methods:

  • A system comprising a wetness sensor and an electronics unit was designed.
  • The sensor is integrated into underwear to detect urine overspills from the pad.
  • The electronics unit provides a vibrating alert to the wearer upon detection of leakage.

Main Results:

  • The described system effectively detects urine leakage from continence pads.
  • The system provides a timely and discreet alert to the wearer, indicating pad failure.

Conclusions:

  • This sensor and electronics system offers a practical solution for monitoring continence pad performance.
  • The technology has potential applications for individuals managing urinary incontinence in both community and care home settings.
