Abstract
A system and method for degassing a fluid in a syringe comprising and inserting the fluid into a negative pressure device. The system may include a holder for holding the syringe; a guide affixed to the holder; a slide for holding a plunger of the syringe, the slide being movably attached to the guide; and a locking mechanism opposite the holder for maintaining a position of the slide. The fluid degasses when the locking mechanism maintains the position of the slide. The system may also include a piercing element adjacent the holder for piercing the syringe. The system and method may also be used for removing fluid from a negative pressure device.

A system for degassing a fluid in a syringe comprising:
- a holder for holding the syringe;
- a guide affixed to the holder;
- a slide for holding a plunger of the syringe, the slide being movably attached to the guide;
- and
- a locking mechanism opposite the holder for maintaining a position of the slide, wherein the fluid degasses when the locking mechanism maintains the position of the slide.
A degassing tool for degassing a fluid in a syringe comprising:
- a holder for holding the syringe;
- a guide affixed to the holder;
- a slide for holding and moving a plunger of the syringe, the slide being movably attached to the guide;
- and
- a piercing element adjacent the holder for piercing the syringe.
A method for degassing a fluid comprising:
- inserting a syringe into a degassing tool;
- drawing a fluid into the syringe;
- closing the syringe;
- retracting a plunger of the syringe to create a vacuum in a portion of a barrel of the syringe;
- locking the plunger using the degassing tool;
- expelling gas dissolved in the fluid into the vacuum in the portion of the syringe;
- and
- expelling the gas in the vacuum out of the syringe.

- inserting a syringe into a degassing tool;
- drawing a fluid into the syringe;
- closing the syringe;
- retracting a plunger of the syringe to create a vacuum in a portion of a barrel of the syringe;
- locking the plunger using the degassing tool;
- expelling gas dissolved in the fluid into the vacuum in the portion of the syringe;
- expelling the gas in the vacuum out of the syringe;
- inserting the syringe into the negative pressure device;
- and
- opening the syringe.
A method for filling a negative pressure device comprising:
- inserting a syringe into a degassing tool;
- closing the syringe;
- retracting a plunger of the syringe to create a vacuum in a portion of a barrel of the syringe;
- locking the plunger using the degassing tool;
- inserting the syringe into the negative pressure device;
- and
- opening the syringe.
