The model is of a supine adult male and extends from the upper buttocks to the lower neck. Positioned in the mid scapulary line, the ultrasound tissue insert contains chest wall superficial tissue, 6th, 7th, 8th, and 9th ribs and intercostal spaces, pleural cavity with lung and atelectatic lung, diaphragm, and superior spleen. The pleural fluid collections allow users to develop and refine their ultrasound guided thoracentesis skills.
