ABSTRACT:
The invention is an improvement on rotors in peristaltic pumps for advancing enteral feeding solutions through medical tubing. The improvement comprises the provision of a plurality of removable, one-piece rollers disposed between the front and rear plates of a rotor. Each of the rollers is contained between a pair of vertically aligned, open channels provided in the front and rear plates. To permit free rotation of each roller within its respective pair of channels, an inner portion of each channel has dimensions slightly larger than the outer ends of each roller. To ensure that the rollers are, during normal use, retained within their respective channels, an outer portion of each channel has dimensions slightly smaller than the dimensions of the end of each roller. Each roller may be inserted or removed into its respective pair of channels by force-fitting the ends of that roller through the outer portion of each channel. Alternatively, the roller ends may be captured within a circular, closed channel within the front and rear plates. In this alternate embodiment, the rollers are removed by separating the front and rear plates.
