Abstract

The present invention relates to liquid drug medical devices for enabling the administration of liquid drugs, and also a needle shield removal device for safely removing needle shields.

Claims

1. A liquid drug medical device for use with a source of physiological solution and a medicinal vessel for administration of a liquid drug, the device having a longitudinal axis, and comprising:

(a) a body member having a first port for fluid connection with the source of physiological solution, said first port being co-directional with the longitudinal axis;

(b) a flow control member rotatably mounted in said body member about an axis of rotation, and having a first major flow duct and a second major flow duct respectively terminating at a second port, and a third port for administering the liquid drug; and

(c) a manually rotatable vial adapter for receiving the medicinal vessel, the manually rotatable vial adapter having a fluid conduit member with a proximal end in flow communication with said second port and a distal end adapted to extend into the medicinal vessel on its attachment to said vial adapter, and coupled to said flow control member for rotating the flow control member between a first flow control position which connects said first port with said second port, and a second flow control position which connects said first port with said third port,

said axis of rotation is co-directional with the longitudinal axis, and said first major flow duct and said second major flow duct are both substantially parallel to and non-coaxial with said axis of rotation and wherein said distal end of the fluid conduit member extends into a recess in the vial adapter.

2. The device according to claim 1 wherein said vial adapter is detachable from said body member at said second flow control position along a line of detachment co-directional with the longitudinal axis.

3. The device according to claim 2 wherein said first port has a screw thread for screw threadingly receiving the source of physiological solution in one direction and said adaptor screw threadingly detaches from said body member in an opposite direction.

4. The device according to claim 3 wherein the device is packaged in a sterile packaging and said body member has at least one laterally protruding member for stopping against an internal longitudinally directed stopper on the inside of the sterile packaging on screw threading the source of physiological solution into said first port whereupon said flow control member is urged into said first flow control position.

5. The device according to claim 4 wherein said vial adapter has a stem including said fluid conduit member and a bore parallel thereto and co-extensive therewith for accommodating a drug dispenser coupled to said third port.

6. The device according to claim 5 wherein said third port is fitted with a needle stick.

7. The device according to claim 5 wherein said third port is fitted with an atomizer.
