Pocket catheters are the same as standard catheters, with the added feature of be concealable. They are discreet enough to be carried around in a pocket, a purse, briefcase, backpack, or makeup bag. Some pocket catheters are so compact that they can be hidden within the palm of the hand. They are packed in small packets and can be carried around in the pocket as the name suggests.
Intermittent catheters are used when there is a need to empty the bladder occasionally. They are required to be inserted for a short duration, as & when required, to drain out the bladder completely.
Intermittent catheters are straight tubes of flexible plastic or rubber that are used to drain the body of urine when the person is not able to do so naturally. One end is rounded while the other is funnel shaped.
