Multiple compartment syringe

摘要

Various syringe systems are disclosed. One illustrative syringe system may include a syringe body having a hollow lumen and a distal end. The syringe body may be configured to house a plurality of fluids therein. A first plunger may be positioned in the hollow lumen of the syringe body, forming a first seal with an inner wall of the syringe body, and forming a first compartment between the first plunger and the distal end of the syringe. A second plunger may be positioned proximal to the first plunger in the hollow lumen of the syringe body, forming a second seal with the inner wall of the syringe body, and forming a second compartment between the first plunger and the second plunger. A plurality of recesses may be disposed about the inner wall of the syringe body near the distal end of the syringe body.

1. A syringe system comprising:
a syringe body comprising a hollow lumen and a distal end comprising a syringe tip, the syringe body being configured to house a plurality of fluids therein; a first plunger positioned in the hollow lumen of the syringe body, forming a first seal with an inner wall of the syringe body, and forming a first compartment between the first plunger and the distal end of the syringe; a plurality of recesses disposed about the inner wall of the syringe body near the distal end of the syringe body; a second plunger positioned proximal to the first plunger in the hollow lumen of the syringe body, forming a second seal with the inner wall of the syringe body, and forming a second compartment between the first plunger and the second plunger; and a transfer tube in fluid connection with the second compartment and the syringe tip, wherein the first plunger, upon contacting the plurality of recesses, breaks the first seal with the inner wall of the syringe body, causing fluid contents of the second compartment to flow distally into the first compartment.
