Percutaneous irrigation and drainage system
First Claim
1. A percutaneous system for irrigating and draining a cavity containing an abscess, sterile fluid collection, hematoma or the like, the system comprising in combination:
- (a) an irrigant reservoir;
(b) a first three-ported connector having first, second, and third ports, and adapted to fluidically connect two of its three ports at a time;
(c) first coupling means for coupling the reservoir to the first port of the first connector;
(d) a syringe connected to the second port of the first connector;
(e) a second three-ported connector having first, second, and third ports, and adapted to fluidically connect two of its three ports at a time;
(f) second coupling means for coupling the third port of the first connector and the first port of the second connector;
(g) a catheter having a distal end adapted to be placed in the cavity, and having an opposing proximal end;
(h) third coupling means for coupling the proximal end of the catheter to the second port of the second connector; and
(i) collection means for collecting fluids draining from the cavity, said collection means being coupled to the third port of the second connector.

Abstract
A closed system for percutaneous irrigation and drainage of cavities containing abscesses, sterile fluid collections or hematomas includes an irrigant reservoir; an irrigation tube connects the reservoir to a first port of a first three-ported connector adapted to fluidically connect two of the three ports at a time. A syringe is connected to the second port of the first connector, and an extension tube connects the third port of the first connector to a first port of a second three-ported connector adapted to fluidically connect two of the three ports at a time. The distal end of a drainage catheter is adapted to be placed in the cavity. The proximal end of the catheter is connected to the second port of the second connector. A drainage tube is connected to the third port of the second connector to a means for collecting fluids draining from the cavity.

7. A method for percutaneously irrigating and draining a cavity containing an abscess, sterile fluid collection, hematoma, or the like, the method comprising the steps of:
-
(a) supplying irrigation fluid from an irrigant reservoir to a first port of a first three-ported connector adapted to fluidically connect two of its three ports at a time; (b) coupling a syringe to a second port of the first connector; (c) coupling the third port of the first connector to a first port of a second three ported-connector adapted to fluidically connect two of its three ports at a time; (d) coupling the third port of the second connector to a collection container; (e) installing a distal end of a catheter in the cavity, the distal end of the catheter having drainage holes therein; (f) coupling a proximal end of the catheter to a second port of the second connector; (g) configuring the first connector to fluidically connect the first and second ports of the first connector, thereby establishing a flow passage between the irrigation tube and the syringe; (h) withdrawing a preselected volume of the irrigation fluid from the irrigant reservoir to the syringe; (i) configuring the first connector to fluidically connect the second and third ports of the first connectors, thereby establishing a flow passage between the syringe and the second connector; (j) configuring the second connector to fluidically connect the first and second ports of the second connector, thereby establishing a flow passage between the syringe and the catheter; (k) forcefully expelling the irrigation fluid from the syringe, thereby causing the irrigation fluid to flow into the catheter to irrigate the catheter and adjacent cavity; (l) configuring the second connector to fluidically connect the first and second ports of the second connector, thereby establishing a flow passage between the catheter and the collection container; and (m) draining fluid from the cavity through the catheter into the collection container. - View Dependent Claims (8, 9)
