The present invention relates to a microneedle therapy system for skin care, hair loss treatment, obesity treatment, and the like. Provided is a multi-injection microneedle therapy system which implements a new treatment device and method capable of inserting a number of needles to create holes on the human skin and simultaneously inject drugs by using a gun, thereby significantly reducing a procedure time, minimizing pain, and increasing drug absorption efficiency to maximize treatment effectiveness. In addition, the multi-injection microneedle therapy system can perform microneedle therapy or mesotherapy treatment according to types of injected drugs and effectively perform the mesotherapy treatment by performing a number of injections for a short procedure time.

A handheld instrument for minimizing pain during administration by injection of a liquid, such as, an anesthetic that has a main body, a vibration unit mounted in the main body when initiated to cause the main body to vibrate, and a detachable tip cantilever mounted on the main body to vibrate with it, the tip having a free end characterized by a bifurcation to form two spaced projections defining a space between them, whereby the spaced projections can be placed in proximity to, adjacent to and bracketing a preselected injection site on a human or animal and the tissue at said preselected injection site and vibrated while an injection is given.

A method for providing localized heating of the dermal layers of skin of a patient, using energy in the form of a group of pulses having defined parameters in a controlled manner. This method preferably uses an optical delivery system to deliver pulsed energy to a specific spot of skin so that targeted layers of the affected skin are heated to a desired temperature range. The temperature range is optimally selected to maximize treatment efficacy while minimizing pain to the patient. Example applications include reducing wrinkles, acne, hair, scar tissue, warts, and promoting wound healing. In this method, the temperature of the selected locus rises quickly to the desired temperature range, then is maintained within a controlled range with a relatively flat temperature profile. The method maintains the temperature by controlling one or more of a pulse energy intensity, pulse width, and pulse frequency or time delay between pulses.

Provided is a method of manufacturing a hollow microneedle structure. The method includes coating a hollow core having a predetermined section and being long in a lengthwise direction with a coating solution, and solidifying the coating solution to form a coating layer, depositing a metal seed layer on the coating layer, plating the seed metal layer with a metal to form a plated layer, cutting the hollow core having the plated layer at an inclination angle with respect to the lengthwise direction for form a surface inclination, and removing the hollow core and the coating layer to form a hollow microneedle structure. Thus, the hollow microneedle structure can be manufactured to have such diameter, length, hardness, and inclination angle as to minimize pain. By use of the hollow core, the microneedle structure can have vertical microneedles with a uniform inner diameter.

An instrument, article and method are provided for minimizing pain during administration by injection of a liquid, such as, an anesthetic. The instrument has a forward end. A rod or lightpipe mounted freely for vibration projects out of the forward end. The article, a single use tip, is composed of a tip sleeve removably mounted on the forward end of the instrument and a tip member removably mounted on the projecting rod or lightpipe to vibrate a preselected injection site on a human or animal. The tip sleeve and tip member are covered by an elastic overmold that enables the tip member to vibrate freely with respect to the tip sleeve and light from the lightpipe to illuminate the injection site. The overmold of the single use tip is torn during removal of the single use tip from the instrument.

An implantable subcutaneous cardiac device includes at least two subcutaneous electrodes adapted for placement external to a heart beneath the skin of a patient. The device further includes an arrhythmia detector that detects a sustained tachyarrhythmia of the heart and a pulse generator that delivers anti-tachycardia pacing pulses to the subcutaneous electrodes in response to detection of a sustained tachyarrhythmia. The pacing pulses preferably have waveforms devoid of any exponential voltage decay and include rounded or substantially constant portions to minimize pain.

Provided is a safety lancet including a reload double prevention structure for preventing a sliding block having a lancet needle from being reloaded to obtain blood, thereby fundamentally preventing reuse of the safety lancet. In addition, the safety lancet guides the sliding block to be straightly discharged without shaking, thereby minimizing pain when the lancet needle is inserted into a skin. The safety lancet includes an outer case forming a space part therein, an inner case sliding along the space part of the outer case, and having a through hole in a front end thereof, and a sliding block coupled to the inner case to straightly move along an inner portion of the inner case, and elastically supported within the outer case by a coil spring, wherein the sliding block comprises a lancet needle having an end protruding from a front end thereof, and a pair of loading hooks on both sides of a rear end thereof to engage with engagement protrusions of the inner case. As the inner case is moved rearward, when the sliding block is disengaged from a portion of the inner case, the sliding block is moved forward by elastic force of the coil spring to temporarily expose the lancet needle out of the inner case, and is then moved rearward to the inner case.

The invention discloses an alginate dressing. The alginate dressing is composed of a three-layer structure, including a collagen / alginate layer, a manganese dioxide layer, and a liquid silicone rubber layer. The layers interact with each other through physical and chemical interactions. It is bonded into an alginate dressing layer similar to a single-layer structure; the preparation process is simple and the use is convenient. Among them, the collagen / alginate layer is obtained by absorbing fish scale collagen enzymatic hydrolysis solution on the alginate membrane matrix obtained by biopolymer material using 3D printing technology; the manganese dioxide layer is obtained by encapsulating manganese dioxide in a cyclodextrin solution The liquid silicone rubber layer is obtained by mixing and vulcanizing silver-loaded polyethyleneimine and liquid silicone rubber; the synergistic effect between the layers makes the dressing not only have excellent water absorption and antibacterial properties, but also provide oxygen and Nutrients provide a suitable microenvironment for wound healing, promote wound healing, shorten the healing cycle, and relieve pain for patients.
