<p>Fluid feed apparatus principally for medical use in which a reservoir supplies fluid to a thick-walled narrow-bore flexible tube (8) whose length and bore (10) are selected in accordance with the desired rate of fluid flow. Means are provided for maintaining a positive pressure of fluid in the reservoir; for example the reservoir may comprise a resilient inflatable bladder (2), which can expel its content over a long period without the need for active monitoring.</p> |
