None of the catheter retainers presently commercially available are entirely satisfactory. Surgeons therefore still quite frequently stitch a catheter to the skin of the wearer. This is frequently done when it is desired to dra in a wound and yet hold the wound largely closed. This procedure of course involv es a risk of infection and may be painful for the patient. Prior art catheter retainers are unsatisfactory for a number of reasons. Firstly the retainer may be size dependent. In other words, for catheters of different diameter, a different catheter retainer device may be required. Another disadvantage is that known catheter retainers are often hard and rigid, and therefore uncomfortable to wear. Wearing them may promote lesions or maceration of the skin and so give rise to problems other than that for whic h the patient is in hospital. Another disadvantage of known catheter retainers is that they are hard to clean. Also, when used with catheters which are of a silicone rubber, a material commonly used for catheters, the catheter tubes are hard to lock in position relative to the retainer because of the slipperynes s of the tube. As a result, patients can inadvertently pull catheters out. Yet another disadvantage of known catheter retainers is that the clamping pressu re which most of them need to apply tends to collapse the catheter or the drainage tube. In consequence, the efficency of drainage is adversely affected. The invented catheter retainer has a pad of medical grade adhesive capable of attachment to the body of a person who has to use a catheter. The pad carries a member to which is secured a cotton or synthetic fibre thread, or a thread of like material. In use the thread is wound around the catheter an d fastened off by being attached to the member. The member is preferably slotted for this purpose.
