Ultrasound-guided invasive procedures, such as central venous catheter insertion, soft-tissue abscess drainage, and foreign-body removal are essential competencies for Emergency Physicians. Such competencies can be trained using ultrasound phantoms.
Our aim is to describe ultrasound phantoms that are easily made, inexpensive, reusable, and can withstand multiple punctures.
Previously recommended gelatin-only ultrasound phantoms have inadequate surface tension resulting in surface disruption, and cannot tolerate multiple punctures when simulating cyst drainage.
By covering the gelatin phantom with a hydrocolloid skin dressing, we are able to minimize physical surface disruption (by transducer or needles) and might reduce biological breakdown due to bacterial propagation.
The elements required to construct homemade reusable ultrasound phantoms are inexpensive and can be easily obtained.
超声引导下的侵入性操作，如中心静脉导管插入、软组织脓肿引流和异物取出，是急诊医生的基本技能。这些技能可以使用超声模拟体模进行培训。
我们的目的是描述易于制作、价格低廉、可重复使用且能承受多次穿刺的超声模拟体模。
先前推荐的仅由明胶制成的超声模拟体模表面张力不足，导致表面破坏，在模拟囊肿引流时不能耐受多次穿刺。
通过用水胶体皮肤敷料覆盖明胶体模，我们能够最大程度减少（由换能器或针造成的）物理表面破坏，并可能减少由于细菌繁殖导致的生物降解。
构建自制可重复使用超声模拟体模所需的材料价格低廉且易于获得。
