ADAPTOR FOR SYRINGE AND SYRINGE COMPRISING ADAPTOR
Document Type and Number:
WIPO Patent Application WO/2024/038565
Kind Code:
A1
Abstract:
This adaptor for a syringe comprises: a first member that has a first through-hole that passes from a first end to a second end in the axial direction; a second member that has a second through-hole that passes from a third end to a fourth end in the axial direction, the third end being fixable to the first member and the fourth end being fixable to the distal end of a syringe; and a valve member that is disposed between the first member and the second member and that can be switched between a state of allowing communication between the first member and the second member and a closed state. The first member and the second member are fixed to each other by means of fixing structures formed respectively on the outer circumferential surface on the second end side of the first member and on the inner circumferential surface on the third end side of the second member. The valve member is displaced and deformed and can thus be switched between the state of allowing communication between the first member and the second member and the closed state.
