The airbag on joint supports is designed to effectively support and protect the injured joint while maintaining comfort. From a practical market perspective, the joint support is a disposable, intimate medical product that does not encourage cross-use for hygienic reasons,and cost considerations are also a reason for the airbag design.
The modular design of the airbag allows the patient to tear the joint support to adjust the length according to their needs during the operation, and to adjust the tension through the Hook and loop cable tie to protect the injured area accurately.
