Patent Application
20200188610
Embodiments disclosed herein relate, in general, to a medical device and, more particularly, to a medical device having a multi-needle assembly.
Changes in environment have adverse effect on human health. The polluted air we breathe or exposure to UV radiations put humans at a higher risk of health issues such as, damage or loss of skin/tissues. Further, these health issues can alter tissue structures and/or functions which may further result in skin laxity, tightness, hair loss, etc. Several available medical tools facilitate delivery of aesthetic, and/or therapeutic compounds or formulations directly into the layers of the skin to overcome such tissue/skin conditions. However, such medical tools are not effective to overcome and/or reduce the tissue/skin disorders. For example, conventional micro needling treatment applies a patient's own plasma to the skin and then performs the micro needling to the skin, for example, facial skin, to have the serum penetrate the skin. In addition, these conventional devices attempt to infuse target areas of the skin such as, face and scalp, with concentrated stem cells, collagen and growth hormone extracted from the patient's own blood. However, these micro needling causes multiple facial punctures to stimulate plasma growth by damaging the superficial layers of the skin. These micro needling tools and its usage for treatments of skin/tissue disorders are not effective because the punctures in the superficial layers of the skin cause bleeding out to the surface. In addition, these micro needling tools do not penetrate plasma into the dermis and epidermis of a patient.
Moreover, conventional needle platform tools have a limited number of needles, for example, five or seven needles on the head to inject mesotherapy medications in order to dissolve fat. In addition, the platform space between needles are too distant, which is not beneficial for injecting plasma for skin and scalp injections. These needles are too long and thick (0.5 inches long & 27 gauge thick) to be used effectively for infiltrating epidermis of the skin with PRP (platelet rich plasma), hyaluronic acid and/or anti-inflammatory steroid.
Accordingly, it is desired to provide an improved medical tool for treatment of skin/tissue disorders and hair loss.
