1. Safe Head Immobilization: The head immobilization ensures a firm and reliable fixation of the patient's head during spinal surgery, minimizing head movement and ensuring stability throughout the operation or treatment. This allows surgeons and healthcare professionals to perform procedures with the precision. 2. Rigid Structure: Favorable for continuous CPR and heart compression resuscitation during transfer. It can let an adult swim in water with normal temperature, which significantly reduces the difficulties of water rescue swimmers and helps the wounded to recover faster. 3. Adjustable Fit: It is designed to adapt to a variety of head sizes and shapes and provide a comfortable fit for patients. Adjustable shoulder straps and padded supports ensure positioning and fit for increased patient comfort. 4. Two Round Ear Holes: This head immobilizer features two round ear holes on both sides of the head to see bleeding or drainage. The emphasis is on ergonomics and provides the right support for the head and neck, promotes correct alignment and reduces the risk of strain or discomfort to the patient.
