The tube includes a first lumen, a second lumen, and a plurality of holes extending from the first lumen therethrough. The balloon is proximal to the holes, is in communication with the second lumen, and is configured to be inflated to hold the tube in place within a patient's rectum. The first valved port is in communication with the first lumen and opens when connected to a first syringe or infusion set to provide medication transmission therethrough and closes when the first syringe or infusion set is withdrawn. The second valved port is in communication with the second lumen and opens when connected with a second syringe or infusion set to provide fluid to inflate the balloon and closes when the second syringe or infusion set is withdrawn. ## Claims ### Claim 1 A rectal medication administration device comprising: a tube comprising a first lumen, a second lumen and a plurality of holes extending from the first lumen through a wall of the tube; a balloon proximal to the plurality of holes and having a cavity therein in communication with the second lumen, wherein the balloon is configured to be inflated to hold the tube in place within a patient's rectum; a first valved port in communication with the first lumen, wherein the first valved port is configured to open when connected to a first syringe or infusion set to provide medication transmission therethrough and to close when the first syringe or infusion set is withdrawn; and a second valved port in communication with the second lumen, wherein the second valved port is configured to open when connected with a second syringe to provide fluid to inflate the balloon and to close when the second syringe is withdrawn; wherein the device is configured to be expelled through a rectal sphincter during defecation. ### Claim 2 (depends on 1) The device of claim 1, wherein a distal-most tip of the tube is closed. ### Claim 3 (depends on 1) The device of claim 1, wherein the device is configured such that when the balloon is inflated in the patient's rectum, the plurality of holes are positioned in a distal portion of the patient's rectum. ### Claim 4 (depends on 3) The device of claim 3, wherein the distal portion of the patient's rectum is a distal โ…“ of the patient's rectum. ### Claim 5 (depends on 1) The device of claim 1, wherein an outer diameter of the tube is between 5.5 to 7 millimeters. ### Claim 6 (depends on 5) The device of claim 5, wherein a diameter of the first lumen is 2 millimeters; and a diameter of the second lumen is less than 1 millimeter. ### Claim 7 (depends on 1) The device of claim 1, wherein each of the first and second valved ports includes a luer lock connector and valve. ### Claim 8 (depends on 1) The device of claim 1, wherein a diameter of each hole of the plurality of holes is between 1.5 and 2 millimeters, and wherein a spacing between neighboring holes of the plurality of holes is between 4 and 6 millimeters. ### Claim 9 (depends on 1) The device of claim 1, further comprising a marker on the tube configured to indicate a depth of insertion of the tube into the patient's rectum. ### Claim 10 (depends on 9) The device of claim 9, wherein the marker is between 3 and 4.5 inches away from a distal-most tip of the tube. ### Claim 11 (depends on 1) The device of claim 1, wherein the balloon has a diameter of approximately 1 inch when fully inflated. ### Claim 12 (depends on 1) The device of claim 1, wherein the first and second lumens run alongside of one another within the tube. ### Claim 13 (depends on 1) The device of claim 1, wherein the balloon is further configured to be deflated to enable insertion and removal of the device from the patient's rectum. ### Claim 14 A rectal medication administration device comprising: a tube comprising a first lumen, a second lumen and a plurality of holes extending from the first lumen through a wall of the tube; a balloon proximal to the plurality of holes and having a cavity therein in communication with the second lumen, wherein the balloon is configured to be inflated to hold the tube in place within a patient's rectum, the balloon having a pliability sufficient to allow the inflated balloon to pass through a rectal sphincter during defecation; a first valved port in communication with the first lumen, wherein the first valved port is configured to open when connected to a first syringe or infusion set to provide medication transmission therethrough and to close when the first syringe or infusion set is withdrawn; and a second valved port in communication with the second lumen, wherein the second valved port is configured to open when connected with a second syringe to provide fluid to inflate the balloon and to close when the second syringe is withdrawn. ### Claim 15 (depends on 14) The device of claim 14, wherein the device is configured such that when the balloon is inflated in the patient's rectum, the plurality of holes are positioned in a distal portion of the patient's rectum. ### Claim 16 (depends on 15) The device of claim 15, wherein the distal portion of the patient's rectum is a distal โ…“ of the patient's rectum. ### Claim 17 (depends on 14) The device of claim 14, wherein the balloon has a diameter of approximately 1 inch when fully inflated. ### Claim 18 (depends on 14) The device of claim 14, wherein the balloon is further configured to be deflated to enable insertion and removal of the device from the patient's rectum.
