A hand-held peristaltic pump 10 comprises a plastic moulded housing 11 in which is mounted a length of elastically deformable plastic tubing 12 which passes through the housing such that ends 12a and 12b of the tube emerge at opposite sides of the housing 11. The tube passes between a battery driven electric rotor 15 and a stationary clamp 16. The clamp 16 is mounted in the housing 11 such that it may slide along an axis parallel to line A-A' of Figure 1. The clamp 16 is biased towards the position shown in Figure 1 by a stainless steel leaf spring 18 and may be manually displaced therefrom by depressing a pair of pivoting arms 19 located on opposed sides of the housing 11, for example to enable the tube to be flushed. |
