Abstract:
The declining number of ultrasound-guided obstetric procedures in clinical practice mandates a shift toward simulation-based teaching. Current uterine simulation aids are animal tissue-sourced or expensive, and improvement is needed. We describe a low-cost reusable uterine model with "fetus," cord and skin, constructed from synthetic gel and silicone rubber. Ultrasound appearance and tactile feedback approximate clinical use, and all parts of the model are portable, durable, and shelf-stable. Those made of ballistics gel can be recycled numerous times without noticeable effect. This appears to be ideal for proctored learning and independent practice within an ultrasound procedural curriculum.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
