CIVCO's eTRAX Storage System utilizes a two-part system consisting of a custom reusable ultrasound system storage adapter and the disposable snap-on storage guard. The storage adapter provides a convenient location for storing both the eTRAX sensor and general purpose sensor when not in use. The disposable snap-on storage guard allows the user to safely set the reusable needle handle and sensor aside during procedures without damaging the delicate sensor. Protects expensive sensors from physical damage and impact with other objects when not in use. The adapter provides a stable and upright position for sensors during the procedure. Single-use design of the storage guard reduces the risks associated with cross-contamination, improving safety for patients and clinicians.
