A urethral catheter device and an associated method of using the device
are disclosed. The device comprises a catheter probe and at least one
receiving unit attachable to the probe for receiving and collecting
urine. The catheter probe comprises: an elongated shaft, a valve, a
drainage lumen, a drainage inlet, a tapered cone, a collar, an elongated
protuberance, a saline inlet, a saline lumen, a sheath, and a fluid lock.
Each receiving unit comprises: a sterile membrane, a sleeve, and a
collection bag. When the sleeve of the receiving unit is attached to the
collar of the catheter probe, then the tapered cone of the catheter probe
ruptures the membrane of the receiving unit, whereby the drainage inlet
of the proximate end of the catheter probe is fluidly connected to the
collection bag of the catheter probe and the valve is thereby opened. The
sheath attached at the proximate end of the elongated shaft is inflatable
into a donut shaped balloon which is capable of being retained within a
bladder of a patient. The method of using the device comprises the steps
of aligning, forcing, holding, injecting, inserting, lubricating,
positioning, releasing, removing, sliding, slipping, turning, and
twisting.
