Title:
再使用不可タイプの注射器
Document Type and Number:
Japanese Patent JP2007530133
Kind Code:
A
Abstract:
The present invention encompasses a syringe of non-reusable type comprising: a container, a rod cooperating with the container, a piston unit inserted in and reciprocally disposed in the container, and a needle, the rod being, by an axial displacement movement, moveably disposed reciprocally in said container and displaying in its one end portion enclosed by the container a first coupling device within a two-part coupling arrangement whose second coupling device is related to said piston unit. Said two coupling devices assume a mutually cooperating and active position while the piston unit is, by the movement of the rod, displaced from a position closely adjacent the needle to a position distal from the needle and causes said coupling devices to be gradually brought to an inactive position while the piston unit is, by the movement of the rod, displaced from the distal position in relation to the needle towards and/or to the position closely adjacent the needle, the two coupling devices permitting, in an inactive position, an axial movement of the rod to take place without cooperation with the piston unit. Said second coupling device is provided with means which is rotatably coordinated with a piston included in said piston unit.
