Methods for Medication Administration

Abstract

Apparatuses and methods for medication administration via a body cavity. In one aspect, a medication administration device includes: a tip portion having a plurality of holes and a balloon defining a balloon cavity. When the balloon is deflated the tip portion can be inserted into a body cavity, such as rectum, to allow medication delivery through the holes in the tip portion. When inflated, the balloon can prevent the tip portion from being withdrawn from the body cavity and/or hold dispersed medication within the body cavity. The device further includes a port portion that has a first port and a second port, and an elongated tubular portion that is coupled between the tip portion and the port portion. The tubular portion has a first lumen connecting the first port to the plurality of holes in the tip portion, and a second lumen connecting the second port to the balloon cavity.

1 . A method, comprising:
 providing a device having a tip portion, a port portion and an elongated tubular portion coupled between the tip portion and the port portion, the tip portion having a plurality of holes and a balloon, the port portion having a first port connected by a first lumen in the tubular portion to the holes in the tip portion, the port portion having a second port connected by a second lumen in the tubular portion to the tip portion to inflate or deflate the balloon;   inserting the tip portion of the device into rectum of a patient while the balloon is deflated;   inserting a first syringe into the second port to inject a predetermined amount of water into the balloon to inflate the balloon;   removing the first syringe from the second port;   inserting a second syringe into the first port to inject medication in a liquid form or a suspension form into the first lumen for dissemination in a distal portion of the rectum; and   removing the second syringe from the first port until a next scheduled medication time.   
   
   
       2 . The method of  claim 1 , further comprising:
 injecting a predetermined amount of water into the first lumen to flush medications from the first lumen into the distal portion of the rectum.   
   
   
       3 . The method of  claim 2 , further comprising:
 inserting an empty syringe into the second port to remove water from the balloon to deflate the balloon; and   removing the tip portion of the device from the rectum after the balloon is deflated.   
   
   
       4 . The method of  claim 1 , further comprising:
 periodically disseminating medication to the distal portion of the rectum through the first port without removing the tip portion of the device from the rectum.
