AI Technical Summary
Existing targeted transdermal drug delivery devices are difficult to accurately target lesions on the back, causing the medicated patch and electrode to shift, which cannot meet the self-treatment needs of patients living alone or with limited mobility.
The device employs a support bladder and push plate design. The push plate is driven to move by a drive component, allowing the support bladder to adapt to the shape of the lesion and fit closely. Combined with the pressure adjustment of the air bladder, a tight fit between the medicated patch and the electrode pad is achieved. The air bladder pressure is automatically adjusted by a pressure sensor and a control valve.
It achieves adaptive and tight fit between the medicated patch and electrode pads and the lesion location, avoiding skin damage caused by misalignment and excessive pressure, improving the versatility of the device and the continuity of treatment effect, and is especially suitable for scenarios where the lesion location cannot be seen when operating it yourself.
