Title:
DOUBLE INJECTING DEVICE
Document Type and Number:
Japanese Patent JPH03149061
Kind Code:
A
Abstract:
PURPOSE: To easily and quickly carry a chemical in safe and sterile state by arranging a spike so that the sharp end pierces an upper stopper when a vial is connected to an injecting device, and providing a fluid flow through the spike, a passage, and a bore between the vial and a port. CONSTITUTION: The inner screw thread 35 of a socket 34 is statically connected to the stopper 42 of a vial 40 when the open end part 41 of the vial 40 is screwed into the outer screw thread 44 through the stopper 42. Thus, the tip of a needle 32 is aligned concentrically with a stopper inlet 45 to insert the vial to a guide surface 38. When the stopper 42 is screwed into the socket 34, the needle 32 gets into the stopper inlet 45 to thrust a seal 46. The vial 40 can be inserted into a device 1 in the state where the stopper 42 is statically connected to the socket 34. Consequently, when a separate preparation device is connected, for example, a chemical P is carried from the vial 40 charged to the rear half to an outlet through the needle 32, a passage 27 and a bore 6.
