    Abstract: The present invention relates to an antimicrobial composition derived from a natural substance. Since the composition effectively suppresses Filobasidium, an organism that has been newly identified as causing dandruff, the present invention can effectively prevent and/or treat seborrhoeic dermatitis and dandruff. Also, since the antimicrobial composition of the present invention includes a natural substance as an active ingredient, little consumer aversion will result. Also, it is expected that the antimicrobial composition of the present invention can be used for developing an antidandruff agent having a reduced content of materials which are typically used as antidandruff agents and the safety of which is questionable.

  • Patent number: 9022997
    Abstract: Provided is a microneedle unit comprising a case having a space accommodating a fluid and a fluid channel through which the fluid is discharged, a microneedle coupled to a lower portion of the case, a base cover disposed at the lower portion of the case, having a hole through which the microneedle passes, and being vertically movable, a guide pin coupled to the base cover and configured to open and close the fluid channel, and an elastic member configured to impart a restoring force such that the base cover is moved upward by an external pressure and then returns downward again. Therefore, the microneedle unit, which is provided to deliver a fluid into the skin with no pain and no scar, can control injection of the fluid using the guide pin, and repeatedly and conveniently control injection of the fluid using the elastic member.

  • Patent number: 9017289
    Abstract: A transdermal fluid delivery device includes a housing defining a longitudinal axis and having a proximal end and a distal end. The housing defines a passageway extending longitudinally therethrough. A fluid reservoir is disposed at the proximal end of the housing in communication with the passageway of the housing and is adapted for retaining a fluid therein. A base member is positioned at the distal end of the housing. A microneedle assembly including a plurality of microneedles extending distally therefrom is also provided. The microneedle assembly is selectively moveable with respect to the housing between a retracted position, wherein the microneedles are disposed within the housing, and an extended position, wherein the microneedles are advanced distally to penetrate the base member and extend distally therefrom for puncturing the patient's epidermis and delivering the fluid into the patient's bloodstream.

  • Publication number: 20150112269
    Abstract: An operation tool for a fluid injector includes an outer cylinder having a housing extending from a first open end to a second open end, and a selective transfer mechanism provided on the outer cylinder. The selective transfer mechanism moves the fluid injector from an initial position to a first protrusion position and then to a second protrusion position in the housing of the outer cylinder. When the fluid injector is at the initial position, the multi-microneedle device has microneedles retracted from the first open end and positioned inside the housing, when the fluid injector is at the first protrusion position, the microneedles are protruded out to a first distance from the first open end, and when the fluid injector is at the second protrusion position, the microneedles are protruded out to a second distance from the first open end. The second distance is shorter than the first distance.

  • Patent number: 8992454
    Abstract: Splitable-tip catheters are disclosed with bioresorbable adhesive to provide spatial separation of distal tip elements during use. The invention can be particularly useful in hemodialysis applications where it is desirable to separate blood extraction and return lumens. The adhesive facilitates insertion of the distal end of the catheter as an assembly, e.g., into a blood vessel using a single guidewire, while the bioresorbable nature of the adhesive allows the tip elements to separate in vivo.
