Multi-port syringe system and method for use with a urinary catheter

A multi-port syringe system wherein:

• the multi-port syringe system is configured for manually irrigating a bladder of a patient selected from the group of a human and an animal;
• the multi-port syringe system comprises a port body, a syringe barrel, and a plunger;
• the port body comprises:
• a port body cylindrical cavity;
• a first port, wherein the first port comprises an aperture through a wall of the port body cylindrical cavity configured for fluid transmission between the port body cylindrical cavity and a first medical device;
• a second port, wherein the second port comprises an aperture through a wall of the port body cylindrical cavity configured for fluid transmission between the port body cylindrical cavity and a second medical device;
• and
• a third port, wherein the third port comprises an aperture through a wall of the port body cylindrical cavity configured for fluid transmission between the port body cylindrical cavity and a third medical device;
• the syringe barrel comprises:
• a cylindrical tube, comprising:
• a cylindrical tube interior configured for storing fluid;
• a syringe barrel central axis located at the center of the cylindrical tube interior;
• a cylindrical tube interior surface;
• and
• a cylindrical tube exterior surface;
• a syringe barrel closed end located on one end of the cylindrical tube;
• and
• a syringe barrel open end located at the opposite end of the cylindrical tube from the syringe barrel closed end;
• a syringe barrel portion comprising:
• the syringe barrel closed end;
• and
• at least part of the cylindrical tube exterior surface located closest to the syringe barrel closed end;
• a syringe barrel port, wherein:
• the syringe barrel port comprises a syringe barrel aperture located in the syringe barrel portion;
• the syringe barrel aperture is configured for fluid transmission into and out of the cylindrical tube interior;
• and
• the syringe barrel aperture is not located on the syringe barrel central axis;
• the syringe barrel portion is configured for:
• nesting inside the port body cylindrical cavity;
• and
• rotating inside the port body cylindrical cavity about the syringe barrel central axis;
• the plunger comprises:
• a plunger circular seal portion configured for:
• insertion into the syringe barrel open end;
• sealing against the cylindrical tube interior surface;
• axial movement inside the cylindrical tube interior to change the volume of fluid in the cylindrical tube interior;
• a plunger grasping feature configured for manual axial movement of the plunger along the barrel central axis;
• and
• a plunger shaft that connects the plunger seal portion to the plunger grasping feature;
• and
• the multi-port syringe system is configured for:
• fluid transmission through the first port when the syringe barrel portion is in a first rotational position wherein:
• the first rotational position comprises:
• a rotation about the syringe barrel central axis;
• a rotation inside the port body cylindrical cavity;
• and
• an alignment of the syringe barrel port with the first port;
• and
• fluid transmission occurs in response to a manual axial movement of the plunger along the syringe barrel central axis;
• fluid transmission through the second port when the syringe barrel portion is in a second rotational position wherein:
• the second rotational position comprises:
• a rotation about the syringe barrel central axis;
• a rotation inside the port body cylindrical cavity;
• and
• an alignment of the syringe barrel port with the second port;
• and
• fluid transmission occurs in response to a manual axial movement of the plunger along the syringe barrel central axis;
• fluid transmission through the third port when the syringe barrel portion is in a third rotational position wherein:
• the third rotational position comprises:
• a rotation about the syringe barrel central axis;
• a rotation inside the port body cylindrical cavity;
• and
• an alignment of the syringe barrel port with the third port;
• and
• fluid transmission occurs in response to a manual axial movement of the plunger along the syringe barrel central axis.
