Pelvic Sling II

The SAM Pelvic Sling II is a specialized circumferential pelvic belt designed for the emergency stabilization of suspected or confirmed “open book” pelvic ring fractures. These severe injuries, often caused by high-impact anteroposterior compression forces, involve the separation of the pelvic bones and can lead to life-threatening internal hemorrhage. The sling’s primary function is to apply controlled, circumferential pressure to close the pelvic volume, reduce bleeding, and stabilize the bony fragments during prehospital patient transport to a definitive care facility.

This device is indicated for application by trained prehospital and medical professionals, including emergency medical technicians, paramedics, and hospital staff. It is intended for use in emergency scenarios where a pelvic fracture is suspected based on the mechanism of injury and patient assessment. Proper application by qualified personnel is essential for both safety and efficacy, as part of a broader trauma management protocol.

The patented AutoStop buckle is the defining safety feature of the SAM Pelvic Sling II. It is engineered to eliminate the critical risk of over-tightening or under-tightening, which is common with traditional straps. The buckle automatically detects when the optimal therapeutic compressive force (approximately 180 N) has been achieved. At this precise moment, two internal prongs activate with an audible and tactile “click.”

This provides immediate, unambiguous confirmation to the provider that correct and adequate compression has been applied. This objective feedback is crucial in high-stress emergency environments, ensuring consistent and effective stabilization for every patient. By standardizing the applied force, the AutoStop buckle helps optimize pelvic volume reduction for hemorrhage control while mitigating the risk of iatrogenic injury from excessive pressure.

The SAM Pelvic Sling II incorporates several robust design features for demanding field use. Its single-piece construction, secured with a Velcro® strapping system, ensures a unified and secure application that resists shifting during patient movement. The materials are engineered to withstand extreme environmental temperatures and resist damage from sharp objects or rough surfaces without compromising function.

Furthermore, the sling is designed to retain wearing comfort even under significant tension, which is vital for patient care during potentially extended transports. A single standard size is scientifically designed to fit approximately 95% of the adult population, streamlining inventory and allowing for rapid deployment without the delay of sizing. These combined features make it a durable, reliable, and user-focused tool for critical trauma intervention.
