Title:
NEEDLE DISK ROLLER DEVICE COMPRISING VISCOELASTIC CONNECTION CAP STRUCTURED TO BE FORCED AGAINST LOWER END OF BOTTLENECK
Document Type and Number:
WIPO Patent Application WO/2018/088676
Kind Code:
A1
Abstract:
Disclosed is a needle disk roller device separably coupled to a medication bottle in which a liquid medication is stored, and which comprises a bottleneck having a predetermined inner diameter. The needle disk roller device comprises: a viscoelastic connection cap separably coupled to the medication bottle so as to cover the upper-end opening of the bottleneck; a roller guiding holder coupled to the upper end of the viscoelastic connection cap; a needle disk roller retained on the roller guiding holder to be able to move linearly; and a medication delivery mechanism for delivering the medication inside the medication bottle to the needle disk of the needle disk roller when the needle disk roller is pressurized against skin. The viscoelastic connection cap comprises: a lower outer barrel portion forced against the outer peripheral surface of the bottleneck when coupled to the upper end of the medication bottle; a lower inner barrel portion inserted into the opening of the medication bottle and forced against the inner peripheral surface of the bottleneck; and a planar ring portion forced against the upper end of the bottleneck so as to connect the inner periphery of the upper end of the lower outer barrel portion and the outer periphery of the upper end of the lower inner barrel portion. The lower inner barrel portion extends further downward past the lower end of the lower outer barrel portion and the lower end of the bottleneck.
