Pneumatic Multi-Directional Neck Traction Collar

The problem

People recovering from neck stiffness or undergoing cervical conditioning often rely on simple traction devices that pull the head straight upward. While vertical stretch has its place, the cervical spine naturally moves in multiple planes—flexion, extension, lateral bending, and rotation. According to the patent, multi-dimensional traction movement can improve the stimulation effect and rehabilitation training effect of the muscles required for various neck movements.

The solution

The patent describes a multi-dimensional movement cervical traction apparatus designed to address this limitation. It uses three distinct organ-type (accordion) airbags positioned between an upper skeleton and a lower skeleton. Both skeletons are ring-shaped with an opening, allowing the device to be wrapped around the neck from back to front.

Three connecting tabs are fixed to the bottom of the upper frame and three to the top of the lower frame, arranged in an equilateral triangle layout. The top of each airbag attaches to an upper tab via a pin shaft and cotter pin, letting the bag pivot. The bottom attaches to a lower tab in the same way. Three separate air intake devices—each consisting of a solenoid valve block and a vacuum pump—connect one-to-one with the airbags through dedicated intake pipes. By coordinating which bags inflate and which exhaust, the frame drives the head through multi-directional movements.

Who it is for

• Physical therapy clinics and rehabilitation centers seeking pneumatic equipment to assist therapists in guiding patients through structured cervical mobility routines without manual manipulation.
• Medical device brands looking to expand their orthopedic or recovery product lines with a multi-axis pneumatic collar that offers more functionality than basic vertical traction units.
• Wellness and massage equipment manufacturers targeting the consumer or professional spa market who want to integrate directional neck-relaxation features into their existing chair or table systems.
• Home-care medical suppliers providing support tools for patients who need consistent, repeatable neck movement protocols prescribed by their healthcare providers.

How it works

The main parts

Operating steps

According to the patent, the device operates by coordinating the inflation and deflation of the three airbags to produce specific head movements:

1. Fitting the device: The upper frame (1) and lower frame (2) are wrapped around the user’s neck (11) from back to front. The left and right airbags sit symmetrically on the sides of the neck, while the third airbag rests at the rear.
2. Extension (tilting back): The left and right airbags are inflated while the rear airbag is exhausted. This drives the head into extension.
3. Flexion (tilting forward): The left and right airbags are exhausted while the rear airbag is inflated. This tilts the head forward.
4. Lateral bending (right tilt): The left airbag is inflated while the right airbag is exhausted, tilting the head to the right. Reversing this (exhausting left, inflating right) tilts the head to the left.
5. Rotation: To drive rotational movement, one side airbag is exhausted while the rear airbag maintains its current length, causing the head to rotate. Changing the side-airbag inflation/exhaust combination reverses the rotational direction.

Applications

Physical therapy clinics

Therapists use traction to guide patients through passive cervical range-of-motion exercises. Instead of manually manipulating the patient’s head, the clinician sets the solenoid valves to cycle through flexion, extension, and lateral bends, ensuring consistent force application across sessions.

Post-surgical rehabilitation

Patients recovering from certain cervical procedures require carefully controlled, gradual mobilization once cleared by a physician. The patent describes the ability to isolate specific directional movements, allowing clinicians to target only the safe planes of motion while avoiding stress on healing tissues.

Ergonomic workplace wellness

Corporate wellness programs sometimes provide relaxation stations for employees experiencing neck fatigue from prolonged desk work. A multi-directional pneumatic collar can offer guided stretching breaks, moving the neck through its full range to relieve static posture tension.

Professional sports recovery

Athletes in contact sports or disciplines requiring high neck mobility (such as swimming or motorsport) use specialized recovery gear. This device provides multi-axis muscle stimulation after intense training, helping maintain flexibility and reduce stiffness.

Home care for chronic conditions

Individuals managing chronic neck tightness under medical supervision can use automated traction at home. The distinct air intake lines allow a caregiver or controller to run pre-set sequences safely without requiring the user to manually pump or adjust the collar.

Where it is less suitable

• Acute spinal injuries or unstable fractures - pneumatic traction of any kind is contraindicated until structural stability is confirmed by a physician.
• Pediatric patients - the frame geometry and airbag volume described are sized for adults; pediatric use would require significant redesign and specialized clinical validation.
• Users requiring continuous high-force mechanical traction - heavy-duty motorized traction tables provide higher sustained loads than pneumatic accordion bags, which are better suited for dynamic, low-to-moderate force mobilization.
