Abstract: A catheter clamp includes a body portion and clamp, the body portion comprising a first location portion which receives a catheter which issues from a patient's skin, a second location portion which causes the catheter to be bent through an arc and a third location portion which guides the catheter to an exit of the clamp, the third location portion comprising side walls which flank the catheter so as to form a close-fitting pathway, the arrangement of the clamp being such that in use the clamp is manually operable and can be caused to adopt a clamping condition in which the clamping portion clamps at least one of that portion of the catheter which is located by the third location portion and that portion of the catheter which is located by the second location portion. The inventive catheter clamp is advantageously of a lower profile than known catheter clamps.
