The 'Necksafe' head articulation control system: a novel cervical immobilisation device

Area of Science:

• Emergency Medicine
• Biomedical Engineering
• Trauma Care

Background:

• Cervical collars are standard for trauma patients to prevent neurological damage.
• Conventional collars offer limited immobilization and can cause complications.
• A novel device, Necksafe, was developed to improve immobilization and reduce issues.

Purpose of the Study:

• To evaluate the efficacy of the Necksafe device.
• To compare its performance against a standard cervical collar.
• To assess comfort and usability in pre-hospital settings.

Main Methods:

• Human volunteers tested Necksafe against the AMBU Perfit ACE collar.
• Cervical Range of Movement (CROM) was measured during standardized movements.
• Ultrasound assessed the impact on jugular vein dimensions.

Main Results:

• Necksafe demonstrated equivalent or superior immobilization in extension, lateral flexion, and rotation.
• Ultrasound findings for jugular veins were inconclusive.
• Paramedics reported Necksafe as more comfortable, easier to fit, and better tolerated.

Conclusions:

• Necksafe offers improved cervical immobilization compared to conventional devices.
• The device enhances patient comfort and airway accessibility.
• Clinical feedback supports Necksafe as a beneficial advancement in trauma care.
