GuideDouble Balloon Pericardiocentesis Gelatin Phantom
This model simulates a pericardial effusion for practicing ultrasound-guided pericardiocentesis. It uses a double-balloon system embedded in colored gelatin to replicate the heart and pericardial space. The inner balloon contains red-dyed water (simulating the heart chamber) and the outer balloon contains blue-dyed water (simulating pericardial fluid), all suspended in green Betadine-tinted gelatin representing surrounding tissue.

GuideInexpensive Reproducible Ultrasound Scrotum Simulators
This guide describes how to build low-cost scrotal ultrasound phantoms using balloons, psyllium husk, and gelatin. The models simulate normal and abnormal testicular anatomy including hydroceles, epididymal cysts, masses, foreign bodies, infarction, and testicular rupture. They were designed for teaching scrotal POCUS technique to medical students and emergency medicine residents. Approximately 12 models can be built for around $20 in about 3-4 hours.
