Abstract

A container system includes a first container assembly and a delivery device. The first container assembly has an administration port and a medication port. The delivery device is attached to the first container assembly, and includes a housing, a connector, a second container, and a plunger shaft. The housing encloses an interior space with the medication port disposed within the interior space. The connector has at least one cannula defining a first sharp end aligned with the medication port and a second sharp end. The second container has an outlet port aligned with the second sharp end of the at least one cannula and a plunger seal moveable within the second container to force contents of the second container through the port. The plunger shaft assembly has a first end that abuts the plunger seal and a second end connected to a trigger.

Claims

1. A container system comprising:

a first container assembly having an administration port and a medication port;

a delivery device attached to the first container, and including;

a housing enclosing an interior space, the medication port disposed within the interior space of the housing;

a connector having at least one cannula defining a first sharp end aligned with the medication port and a second sharp end;

a second container having an outlet port aligned with the second sharp end of the at least one cannula and a plunger seal moveable within the second container to force contents of the second container through the port;

a plunger shaft assembly having a first end that abuts the plunger seal and a second end connected to a trigger, wherein;

the connector having a storage state wherein the first end is not in fluid communication with the medication port and the second end is not in fluid communication with the outlet port, and an operational state wherein the first end is in fluid communication with the medication port and the second end is in fluid communication with the outlet port, and wherein;

the medication port comprises a plug and the outlet port comprises a stopper, and

the first sharp end of the connector is not disposed through the plug in the storage state, and is disposed through the plug in the operational state,

the second sharp end of the connector is not disposed through the plug in the storage state, and is disposed through the plug in the operational state.

2. The container system according to claim 1, wherein:

the medication port, the connector and the second container are aligned along a common axis, and the plunger seal is moveable along the common axis.

3. The container system according to claim 1, wherein:

the plunger shaft assembly is adjustable and comprises first and second shaft sections, the first shaft section defining the first end of the plunger shaft assembly and the second shaft section defining the second end of the plunger shaft assembly, the first and second shaft sections moveable relative to each other to vary a distance between the first and second ends;

and further comprising a lock connected to the first and second shaft sections, the lock having a first state that permits relative motion between the first and second shaft sections and a second state that limits relative motion between the first and second shaft sections.

4. The container system according to claim 3, wherein:

the first shaft section comprises a solid shaft with a first end that defines the first end of the plunger shaft assembly and a second end, and the second shaft section comprises a hollow tube with a first end and a second end that defines the second end of the plunger shaft assembly,

the second end of the solid shaft and the first end of the hollow tube threadedly engaging each other to permit relative motion thereof,

the plunger shaft assembly further comprising a pin disposed in a slot formed in the solid shaft to resist rotational motion of the solid shaft.

5. The container system according to claim 4, wherein:

the hollow shaft has an exterior surface with a plurality of longitudinal grooves; and

the lock engages the longitudinal grooves in the second state to limit relative motion between the solid shaft and hollow tube.

6. The container system according to claim 5, wherein

the lock comprising a lever having a first end, a second end, a spring that biases the first end toward one of the plurality of longitudinal grooves, and a key that abuts the second end of the lever when inserted into the lock to space the first end of the lever from the plurality of longitudinal grooves.

7. The container system according to claim 1, wherein the housing has a window, and the plunger shaft assembly comprises a shaft having an exterior surface from which a tab depends and a longitudinal axis, and further comprising:

a state indicator comprising a collar disposed about the plunger shaft assembly, the collar having an exterior surface visible through the window and an interior surface with a path formed therein, the tab received within the path and the path having first, second and third sections each at an angle to the longitudinal axis of the solid shaft, the first and third sections having an opposite slope to the second section.

8. The container system according to claim 7, the plunger shaft assembly comprising a pin disposed in a slot formed in the shaft to resist rotational motion of the shaft about its longitudinal axis.

9. The container system according to claim 7, wherein the path has fourth and fifth sections each parallel to the longitudinal axis, the fourth section disposed prior to the first section and the fifth section disposed between the first and second sections.

10. The container system according to claim 7, further comprising a safety lock connected to the plunger shaft assembly to limit movement of the plunger shaft assembly.

11. The container system according to claim 1, wherein:

the plunger shaft assembly is automated and comprises a shaft and a biasing element coupled to the shaft, the trigger coupled to one of the shaft and the biasing element to selectively control movement of the shaft from a first storage state to a second operational state wherein the shaft applies a force to the plunger seal.

12. The container system according to claim 11, wherein the shaft has a first end abutting the plunger seal and a second end, and the biasing element abuts the second end of the shaft.

13. The container system according to claim 12, wherein the plunger shaft assembly comprises a latch, the latch moveable from a first locked state wherein the latch limits movement of the shaft and a second unlocked state wherein the latch permits movement of the shaft.

14. The container system according to claim 13, wherein the latch has a tab and the shaft has a slot, and the tab is disposed in the slot with the latch in the first locked state, and the tab is spaced from the slot with the latch in the second unlocked state.

15. The container system according to claim 1, wherein:

the first container comprises a flexible bag with a first, closed end and a second end, and a gondola including the administration port and the medication port sealed to the second end of the flexible bag,

the housing attached to the gondola.

16. The container system according to claim 15, wherein:

the second container comprises a cartridge, with the outlet port of the second container including the stopper through which the second sharp end of the connector is disposed to place the connector in fluid communication with the second container.

17. The container system according to claim 1, wherein:

the administration port is disposed through the interior space of the housing to depend from the housing.

18. The container system according to claim 1, wherein:

the second container is disposed within the interior space of the housing.
