Abstract

A spike connector (10) of the type in which a hollowed spike (14) extending from the main body portion (12) of the spike connector is inserted into the stopper of a fluid source in order to convey the fluid from the source through the spike (14) and main body portion (12). The main body portion (12) includes a pair of wings (32, 34) which extend upwardly in the direction of the spike and outwardly therefrom, with the tops of the wings serving to space the remaining top of the main body portion (12) away from the fluid source stopper to prevent collection of the solution on the top of the main body portion. The undersides (36, 38) of the wings (32, 34) form a convenient finger grip. The tip portion (30) of the spike is relatively polished to enable easy insertion of the spike into the stopper.

Claims

1. A spike connector having a main body portion and a hollowed spike extending therefrom for insertion into the stopper of a fluid source and for conveyance of the fluid from the source through the spike and main body portion, the improvement comprising:

said main body portion including a pair of wings extending upwardly in the direction of said spike but outwardly therefrom, said pair of wings extending away from each other, the undersides of said wings being arcuately constructed to enable an operator to grab said main body portion at said undersides, and the tops of said wings serving to space other than said wing tops away from the fluid source stopper when the spike is inserted into the stopper;

said main body portion having a generally circular cross-sectional configuration perpendicular to said spike and at the end thereof that is distal from said spike, and means adjacent the circular cross-sectional portion for receiving a drip chamber.

2. A spike connector as described in claim 1, said spike connector being molded of polypropylene in an integral, one-piece construction.

3. A spike connector as described in claim 1, each wing forming an included angle of about 45°

between the wing and the axis of the spike.

4. A spike connector as described in claim 1, wherein the main axes of both wings and the spike are coplanar.

5. A spike connector having a main body portion and a hollowed spike extending therefrom for insertion into the stopper of a fluid source and for conveyance of the fluid from the source through the spike and main body portion, the improvement comprising:

said main body portion including a pair of wings extending upwardly in the direction of said spike but outwardly therefrom, said pair of wings extending away from each other, the undersides of said wings being arcuately constructed to enable an operator to grab said main body portion at said undersides, and the tops of said wings serving to space other than said wing tops away from the fluid source stopper when the spike is inserted into the stopper;

the main body portion having four sides, two sides of the main body portion forming the undersides of the wings and the other two sides of the main body portion being narrow and generally planar adjacent the spike but curving outwardly away from the spike.

6. A spike connector as described in claim 5, said main body portion having a generally circular cross-sectional configuration perpendicular to said spike and at the end thereof that is distal from said spike, and means adjacent the circular cross-sectional portion for receiving a drip chamber.

7. A spike connector having a main body portion and a hollowed spike extending therefrom for insertion into the stopper of a fluid source and for conveyance of the fluid from the source through the spike and main body portion, the improvement comprising:

said main body portion including a pair of wings extending upwardly in the direction of said spike but outwardly therefrom, said pair of wings extending away from each other, the undersides of said wings being arcuately constructed to enable an operator to grab said main body portion at said undersides, and the tops of said wings serving to space other than said wing tops away from the fluid source stopper when the spike is inserted into the stopper;

said spike having a relatively polished surface adjacent its tip as compared to the surface adjacent said main body portion.

8. A spike connector as described in claim 7, said relatively polished surface extending from 1.0 centimeter to 1.5 centimeter from said tip.

9. A spike connector formed in an integral, one-piece construction and having a main body portion and a hollowed spike extending therefrom for insertion into the stopper of a fluid source and for conveyance of the fluid from the source through the spike and main body portion, the improvement comprising:

said main body portion including a pair of wings extending upwardly in the direction of said spike but outwardly therefrom, said pair of wings extending away from each other with the main axis of both wings and the spike being coplanar, said main body portion having four sides with two sides of the main body portion forming undersides of the wings and with the other two sides of the main body portion being narrow and generally planar adjacent the spike but curving outwardly away from the spike, said undersides of said wings being arcuately constructed to enable an operator to grasp said main body portion at said undersides, and the tops of said wings serving to space other than said wing tops away from the fluid source stopper when the spike is inserted into the stopper, said main body portion having a generally circular cross-sectional configuration perpendicular to said spike and at the end thereof that is distal from said spike, and means adjacent the circular cross-sectional portion for receiving a drip chamber.

10. A spike connector as described in claim 9, wherein each wing forms an included angle of about 45°

between the wing and the axis of the spike.

11. A spike connector as described in claim 9, said spike having a relatively polished surface adjacent its tip as compared to the surface adjacent said main body portion, said relatively polished surface extending from 1.0 to 1.5 centimeter from said tip.

12. A spike connector having a main body portion and a hollowed spike extending therefrom for insertion into the stopper of a fluid source and for conveyance of the fluid from the source through the spike and main body portion, the improvement comprising:

said spike having a relatively polished surface adjacent its tip as compared to the surface adjacent said main body portion, said relatively polished surface extending from 1.0 centimeter to 1.5 centimeter from said tip, whereby insertion of the spike into the stopper is simplified while greater frictional compression is provided once the spike is inserted into the stopper.
