AI Technical Summary
The application scope of existing TENS technology is limited, especially in meeting the need for pain relief at the injection site for diabetic patients. In addition, existing smart TENS patches are expensive and have a narrow range of applications.
Design a transdermal electrical stimulation patch including a top cover, an electrical stimulation component, and multiple electrode pads. Establish a pulse current transmission path by setting up multi-layer structural components. Achieve electrical stimulation effect by contacting the electrode pads with the human body surface. The patch is non-invasive and includes a hollow chamber to protect the circuit board. The electrode pads are semi-circular to conform to the curves of the human body and have reserved injection holes for injection pain relief.
It achieves non-invasive pain relief with no side effects, is adaptable to different body parts, reduces costs, and provides effective relief for injection pain through pre-reserved injection holes.
