摘要: The invention provides a method of producing a microneedle. A jig is heated to a temperature above the level at which a temperature-sensitive material that exhibits thermoplastic deformation becomes viscoplastic, the jig is brought into contact with the temperature-sensitive material, and then the jig is pulled part from the temperature-sensitive material to elongate the portion of the temperature-sensitive material in contact with the jig, whereby acicular projections are formed.

摘要: Provided is a microneedle device which protects a microneedle, has an easily portable shape, is free from such problems as breakage of small needles in the step of puncturing the skin with the microneedle, and ensures appropriate skin puncture to administer a drug. By studying the relationship between the device to be pressed to the skin and the height of the elevation of the skin surface during the pressing, it is found that there is a positive correlation between the placement and interval of skin fixing members and the height of the elevation of the skin. It is furthermore found that the elevated skin surface is always parallel to the flat plate of the device. This reveals that since the microneedle installed in the device can be inserted at right angle to the skin surface, the skin can reliably be punctuated avoiding the breakage etc. of the small needles of the microneedle. Thus, a microneedle patch which is easily portable and ensures convenient drug administration to the skin can be produced.

摘要: Since all methods of applying a drug liquid to a tip portion of a microneedle are application of the drug liquid in an open system, evaporation of the solvent from the drug liquid is unavoidable, such that the concentration of the drug liquid changes easily, and a large amount of the drug liquid is necessary. The invention provides a method of applying a drug to a pin-frog-shaped microneedle by using a small amount of the solution and without variation of the concentration of the drug liquid. A member having plural grooves is produced, and one end thereof is immersed in a drug liquid tank to fill the grooves with the drug liquid. The drug can be uniformly applied to a tip portion of the microneedle by setting the pin-frog-shaped microneedle to pass through the drug liquid in the grooves.
