Abstract
A catheter for intermittent self-conduction of urine which is relatively hard to deflect easy to insert into a body, and eliminate any pain and danger while in the body. A catheter for intermittent self-conduction of urine comprises an urine conduction tube (1) having an urine conduction aperture (13) in a distal end (11) thereof, a holder (3) coupled to a proximal end (12) of the urine conduction tube (1) and adapted to be detachably engaged with an inlet port (22) of a sterilizing solution case (2) which is adapted to contain a sterilizing solution (21), and a cap (4) for closing an outlet (311) of the holder (3). The urine conduction tube (1) is a dual layer tube including an inner tube member (101) made of a hard synthetic resin material which is medicine-proof and an outer tube member (102) made of a soft synthetic resin material which is medicine-proof. The inner tube member (101) in the urine conduction tube (1) is made of a hard synthetic resin material which is medicine-proof and is selected from a group of polytetrafluoroethylene, olefine base resin, polyamide base resin, and polyester base resin. The outer tube member (102) in the urine conduction tube (1) is made of a soft synthetic resin material which is medicine-proof and is selected from a group of silicone rubber, fluororubber, and butyl rubber.
