The cultural technique of Spencer has been able to identify two kinds of cervical immobilization:
- YES Immobilization, allows the patient to reply “yes” when asks the operator if all is
well.
- Silent immobilization, with all the other devices that to do not
comply with the YES
technology, the patients are obliged to move the head because it is
impossible for them to speak. This movement, commonplace in ordinary
immobilization, could be damaging and cause further serious injury.
The double valve collar is based on a physical principal which permits
transfer to the vertical components, of the physical strength that the
operator applies to the device, when placing it around the patients’
neck. This technique allows for the correct extension
of the cervical column, thus obtaining a neutral alignment, limiting the
possibility of error. The YES collars are realized in thermo-pressed,
biocompatible, closed-cell polyethylene, which guarantees excellent
efficiency and:
- reduces the inflection-extension to the minimum
- minimizes pressure on the carotid
- guarantees X-rays, CAT scan and MRI investigations compatibility
The reduced weight of the primary structure and the unique design have allowed us to:
- increase the opening at the front for an easier access to the carotid artery and to
create a convenient access for the tracheotomy
- re-design the profiles of all collars and reduce the number of sizes available whilst
maintaining the same scientific precision of immobilization
- increase the radius of the borders to improve the comfort of the victim
- increase the thickness and expansive density of the internal lining, to give a decisively
improved level of comfort to the patient
