Abstract
A manufacturing device for a microneedle includes an upper plate stage, a lower plate stage disposed in horizontally parallel with the upper plate stage, a rotating device configured to rotate and move the upper plate stage over the lower plate stage, and a first cylindrical type actuator configured to vertically move the lower plate stage in a state in which the upper plate stage has been rotated and moved over the lower plate stage by the rotating device. The first cylindrical type actuator may upwardly and downwardly move so as to be able to stretch a viscous composition in a vertical direction in a state in which a contacting to the viscous composition is performed, wherein the viscous composition is applied on both of a patch sheet seated on the upper plate stage and a patch sheet seated on the lower plate stage, or is applied on one of them.
Core Innovation
A microneedle manufacturing device positions a first patch sheet on an upper plate stage and a second patch sheet on a lower plate stage. A rotating device rotates and moves the upper plate stage over the lower plate stage so that viscous compositions in the patch sheets are contacted.
A first cylindrical type actuator vertically moves the lower plate stage to stretch the first viscous composition and the second viscous composition to obtain the microneedle. A second cylindrical type actuator is positioned parallel to a vertical axis and vertically moves the upper plate stage until the first viscous composition of the first patch sheet comes into contact with the second viscous composition of the second patch sheet.
The system further provides a monitoring device using image-based correspondence of hole-type position indicators between the patch sheets and hole-type stage indicators. A sensed result is used to select an exact position of the patch sheet, and an optional vacuum absorber performs vacuum suction to fix the patch-sheet position based on the sensed result.
Claims Coverage
The document includes one independent claim covering a microneedle manufacturing system with two patch sheets containing viscous compositions placed on horizontally parallel upper and lower plate stages. The main inventive features are supported and refined by dependent claims that add monitoring based on image-based position indicators, optional vacuum suction position fixing, a specific hole-and-bar position indicator structure, and a specified patch-sheet layer structure.
Two patch sheets on parallel upper/lower plate stages with viscous compositions
A first patch sheet including a first viscous composition and a second patch sheet including a second viscous composition, with an upper plate stage holding the first patch sheet and a lower plate stage disposed in horizontally parallel with the upper plate stage and holding the second patch sheet.
Rotating device to move upper stage over lower stage
A rotating device configured to rotate and move the upper plate stage over the lower plate stage.
Dual cylindrical actuators for vertical movement and contacting/stretching
A first cylindrical type actuator configured to vertically move the lower plate stage and a second cylindrical type actuator positioned parallel to a vertical axis and configured to vertically move the upper plate stage until the first viscous composition comes into contact with the second viscous composition.
Stretching viscous compositions to obtain the microneedle
The first cylindrical type actuator vertically moves the lower plate stage to stretch the first viscous composition and the second viscous composition to obtain the microneedle.
Monitoring device for patch-sheet position
A monitoring device that inspects a position of a patch sheet on an upper plate stage and a lower plate stage.
Image-based correspondence of position indicators for sensed result
The monitoring device senses whether position indicators on the patch sheet correspond via image to position indicators on the upper and lower plate stages, and outputs a sensed result.
Hole-type position indicators for bar-guided vertical storage
A position-indicator on the patch sheet formed as holes in upper and lower portions, where the holes are used for a bar that stores the patch sheet in a vertical direction.
Vacuum absorber to fix patch-sheet position based on sensed results
A vacuum absorber that fixes the position of a patch sheet on upper and lower plate stages by vacuum suction based on the monitoring-device sensed results indicating exact position selection of the patch sheet.
Patch-sheet structure with supporting layer, adhesive layer, and peeling film
The patch sheet includes a supporting layer with an adhesive layer on its upper surface and a peeling film formed on the adhesive layer.
Across the independent claim and refinements, the core coverage combines paired patch sheets with viscous compositions on parallel upper/lower plate stages, a rotating device to move the upper stage over the lower stage, and dual cylindrical actuators to bring the viscous compositions into contact and stretch them to obtain a microneedle. Dependent claims further cover monitoring of patch-sheet positioning using image-based hole-type position indicators, optional vacuum suction fixing based on sensed results, and specific structural details for position indicators and patch-sheet layers.
