Abstract

A device for automatically transferring a piercing pin from the port of one medical liquid container to the port of another medical liquid container. The ports are mounted to the device in opposing relationship. The piercing pin is inverted at an intermediate position between the ports.

Claims

1. A piercing pin transfer device comprising, in combination

a piercing pin;

means to support said pin;

means for holding a first port adapted to connect to said pin;

means for holding a second port adapted to connect to said pin, said second port holding means being in opposing relationship with said first port holding means;

means for connecting said pin to said first port, disconnecting said pin from said port, and connecting said pin to said second port and

means for inverting said piercing pin intermediate of said first port holding means and said second port holding means.

2. The device of claim 1 further comprising means for sterilizing said piercing pin while said piercing pin is being inverted.

3. The device of claim 2, wherein said sterilizing means is a source of ultraviolet irradiation.

4. The device of claim 3, wherein said ultraviolet irradiation source is at a position intermediate of said first and second port holding means.

5. The device of claim 4 further comprising means for moving said piercing pin between said first and second port holding means and means for stopping movement of said piercing pin at said intermediate position.

6. The device of claim 5, wherein said ultraviolet irradiation source radiates from above, below, and in front of said piercing pin at said intermediate position.

7. The device of claim 6, wherein said ultraviolet irradiation source is a single bulb.

8. A piercing pin transfer device comprising in combination

a piercing pin, removably mounted in a support therefor;

means for carrying said piercing pin;

means for holding a first port adapted to connect to said piercing pin;

means for holding a second port adapted to connect to said piercing pin, said second port holding means being in opposing relationship with said first port holding means;

means for housing said piercing pin carrying means and for transferring said piercing pin from said first port holding means to said opposing second port holding means along a linear path defined by linear guide means;

means for inverting said piercing pin carrying means while transferring said piercing pin carrying means along said linear path; and

wherein said transfer from said first port holding means disconnects said piercing pin from said first port, said piercing pin carrier means inverts said piercing pin, and said transfer to said second port connects said piercing pin to said opposing second port.

9. The device of claim 8 further comprising means for sterilizing said piercing pin while said piercing pin is being inverted.

10. The device of claim 9, wherein said sterilizing means is a source of ultraviolet irradiation.

11. The device of claim 10, wherein said ultraviolet irradiation source is at a position intermediate of said first and second port holding means.

12. The device of claim 11 further comprising means for stopping movement of said piercing pin at said intermediate position.

13. The device of claim 12, wherein said ultraviolet irradiation source radiates from above, below, and in front of said piercing pin at said intermediate position.

14. The device of claim 13, wherein said ultraviolet irradiation source is a single bulb.

15. The device of claim 8, wherein said linear guide means comprises:

a lead screw follower supporting said piercing pin carrying means, said lead screw follower having an integral power nut;

a lead screw threadably engaged with said power nut;

a linear guide means guiding said lead screw follower along a linear path; and

means for reversibly driving said lead screw to thereby move said lead screw follower between said first and second port holding means.

16. The device of claim 15 further comprising means for sterilizing said piercing pin while inverting said piercing pin.

17. The device of claim 16, wherein said sterilizing means is an ultraviolet light source.

18. The device of claim 17, wherein said piercing pin is sterilized with ultraviolet irradiation at an intermediate position between the first and second port holding means.

19. The device of claim 18 further comprising means for stopping movement of said piercing pin at said intermediate position.

20. The device of claim 19, wherein said ultraviolet irradiation at said intermediate position is above, below, and in front of said piercing pin.

21. The device of claim 8, wherein said means for inverting said piercing pin carrying means comprises:

a shuttle block having two radial slots;

means for fixedly and rotatably connecting said shuttle block with said piercing pin carrying means;

means for guiding said shuttle block along a linear path; and

two fixed indexing pins disposed in said linear path at a point offset from the linear path of the axis of rotation of said shuttle block, said indexing pins being disposed to engage said radial slots and rotate said shuttle block as said shuttle block is moved along said linear path, thereby rotating said piercing pin carrying means.

22. The device of claim 21 further comprising means for sterilizing said piercing pin while inverting said piercing pin.

23. The device of claim 22, wherein said sterilizing means is an ultraviolet light source.

24. The device of claim 23, wherein said piercing pin is sterilized with ultraviolet irradiation at an intermediate position.

25. The device of claim 24 further comprising means for stopping movement of said piercing pin at said intermediate position.

26. The device of claim 25, wherein said ultraviolet irradiation at said intermediate position is above, below, and in front of said piercing pin.

27. A piercing pin transfer device comprising, in combination:

a housing;

means for carrying a piercing pin, mounted in said housing;

a piercing pin removably mounted in said carrying means;

a first port for receiving said piercing pin;

a second port for receiving said piercing pin, said second port being in opposing relationship with said first port;

means for moving said piercing pin carrying means along a linear path from said first port to said second port;

means, disposed in said housing, for holding said first and second ports;

means, disposed in said housing, for rotating said piercing pin carrying means 180 degrees while moving said piercing pin carrying means along said linear path, thereby inverting said piercing pin;

wherein said linear movement of said piercing pin causes withdrawal of said piercing pin from said first port, and insertion of said piercing pin into said second port; and

means for providing ultraviolet irradiation of said piercing pin between said first and second port.
