A multifunctional, adaptive facial mask delivers cosmetic massage and light therapy in a hands-free format. The mask integrates three elements: (i) internal motion-guiding contours that channel tactile stimulation along anatomically relevant lymphatic paths, (ii) zone-selective actuation using vibration nodes, inflatable micro-bladders, or oscillating pads, and (iii) a flexible Light-Emitting Diode (LED) grid delivering red, near-infrared, and optional blue wavelengths. The soft, medical-grade silicone shell conforms to diverse facial anatomies and maintains a continuous smooth surface that isolates the user from hard mechanics. A microcontroller sequences stimulation across zones (forehead, temple, cheek, nasolabial, jawline, and neck strap) to emulate facial-yoga strokes and lymphatic drainage. Preset modes such as Lift, Recovery, and Glow manage timing, direction, and intensity. Optional enhancements include gentle heat, removable cooling inserts, and low-frequency micro-stimulation. The mask provides an integrated combination of guided internal geometry, sequenced hands-free actuation, and cosmetic light therapy within a flexible, inclusive design.

The application relates to the technical field of medical devices, in particular to a skin ultrasound contrast-based axillary sentinel lymph node puncture guiding method. The core of the method is as follows: after injecting an ultrasound contrast agent with a specific particle size through the skin, a preset low-mechanical-index high-frame-rate double-amplitude contrast imaging mode is adopted to dynamically track lymph drainage and sentinel lymph node development, and the enhancement characteristics are recorded; then, under the guidance of multimodal imaging which is fused with real-time contrast, elastic imaging and color Doppler, the target lymph node is accurately punctured and biopsied, and a tissue sample is obtained for pathological analysis. The application realizes integrated operation from sensitive development of the sentinel lymph node, function evaluation to accurate puncture, and provides a non-radiation high-precision puncture guiding method for accurate evaluation of the axillary lymph node state of breast cancer patients before operation.

An energizing garment comprising a compressive material configured to be worn by a user for therapeutic lymphatic drainage and tissue massage. The garment includes watershed fingers secured to watershed portions of the material that overlie lymphatic watershed regions of the user's body, and massage fingers secured to non-watershed portions that overlie non-watershed regions. The watershed fingers are arranged in a variable density pattern to encourage lymph flow through watershed areas, while massage fingers are arranged in a consistent density pattern to create fluid pathways directing flow from non-watershed regions toward watersheds. The compressive material applies targeted pressure to drive the fingers against the skin and underlying tissues, energizing the tissues to release fluid and smooth the skin. The garment can be formed as various clothing items including shirts, pants, shorts, jumpsuits, or leotards, providing a wearable therapeutic solution for lymphatic system stimulation and tissue treatment.

This invention provides an artificial dura mater material, its preparation method, and its applications, belonging to the field of biomedical technology. Addressing the shortcomings of traditional synthetic dura mater, this invention utilizes poly(L-lactide-caprolactone) (PLCL) with a specific concentration of RAPA, processed using electrospinning. It exhibits low porosity and a dense texture, inducing rapid endothelialization of the dura mater in the early stages of traumatic brain injury. Subsequently, with the release of RAPA, the material's porosity increases, facilitating the proliferation and growth of newly formed dura mater cells. Simultaneously, RAPA can prevent excessive proliferation of new endothelial cells and scar hyperplasia. It can selectively inhibit pathological proliferation without impairing necessary lymphatic drainage; while maintaining the physical structural integrity of the dura mater, it can promote neurological function repair.
