The specific application of TPU airbags in medical devices

TPU (Thermoplastic Polyurethane) airbags are widely used in the medical device industry due to their excellent biocompatibility, wear resistance, high and low temperature resistance, and good elasticity. Specific application scenarios include:

I. Medical Rehabilitation Equipment

Massage and Physiotherapy Devices
TPU airbags are key components in devices such as eye massagers and neck massagers. Through inflation and deflation, they enable massage modes such as compression, tapping, and vibration, mimicking professional massage techniques. For instance, the airbags in eye massagers can adapt to the user’s eye shape, providing precise acupressure to promote blood circulation and alleviate eye fatigue.

Rehabilitation Braces and Supports
TPU airbags are used in customized rehabilitation braces for areas such as the waist, neck, and legs. Pressure is adjusted via inflation to provide personalized support and protection. For example, waist support airbags can help patients maintain proper sitting posture and reduce lumbar pressure.

Pressure Sore Prevention Devices
In hospital beds or wheelchairs, TPU airbags prevent pressure sores in long-term bedridden patients by alternately inflating and deflating to distribute body pressure. Their flexibility and durability ensure the device maintains its shape over long-term use.

II. Diagnostic and Monitoring Equipment

Blood Pressure Cuff Airbags
TPU materials are used in the airbags of wrist and upper-arm blood pressure monitors. Their elasticity and sealing properties ensure accurate blood pressure measurements. Customized designs can accommodate different patients’ wrist sizes, improving measurement accuracy.

Respiratory Support Equipment
TPU airbags are used in anesthesia machine breathing circuits and manual resuscitators as reservoir bags or test lungs. Their chemical resistance and non-toxic properties ensure the safe transmission of breathing gases.

III. Surgical and Emergency Equipment

Surgical Support Airbags
TPU airbags are used during surgery to adjust patient positioning, such as providing lumbar or limb support, ensuring a clear surgical field. Their waterproof and antibacterial properties reduce the risk of infection.

Emergency Immobilization Airbags
In emergency scenarios, TPU airbags are used as splints for limb fractures or torso immobilizers. They enable rapid fixation of injured individuals through inflation, preventing secondary injuries. Their lightweight and foldable design makes them easy to carry and store.

IV. Special Medical Applications

Vacuum Stretchers and Limb Splints
TPU airbags are combined with vacuum stretchers to form fully encapsulated fracture protection air cushions. Rapid fixation is achieved through vacuum suction, making them suitable for disaster rescue or field emergency care.

Veterinary Medical Equipment
TPU airbags are also used in veterinary anesthesia machine breathing circuit accessories, such as reservoir bags and test lungs. Their resistance to corrosion by animal bodily fluids extends the service life of the equipment.
