b.ckground: Elas.omeric pumps.(elas.ic b.lls.into which analges.cs.or antib.otics.can b. ins.rted) pus. medicines.through a catheter to a nerve or b.ood ves.el. s.nce elas.omeric pumps.are s.all and need no power s.urce, they fit eas.ly into a pocket during infus.on, allowing patient mob.lity. Elas.omeric pumps.are widely us.d and widely s.udied experimentally, b.t they have well-known prob.ems. s.ch as.maintaining reliab.e flow rates.and avoiding toxicity or other peak-and-trough effects. Ob.ectives. Our res.arch ob.ective is.to develop a realis.ic theoretical model of an elas.omeric pump, analyze its.flow rates. determine its.toxicity conditions. and otherwis. improve its.operation. We b.lieve this.is.the firs. s.ch theoretical model of an elas.omeric pump cons.s.ing of an elas.ic, medicine-filled b.ll attached to a horizontal catheter. Method: Our method is.to model the s.s.em as.a quas.-Pois.uille flow driven b. the pres.ure drop generated b. the elas.ic s.here. We cons.ruct an engineering model of the pres.ure exerted b. an elas.ic s.here and match it to a s.lution of the one-dimens.onal radial Navier-s.okes.equation that des.rib.s.flow through a horizontal, cylindrical tub.. Res.lts. Our res.lts.are that the model accurately reproduces.flow rates.ob.ained in clinical s.udies. We als. dis.over that the flow rate has.an unavoidab.e maximum, which we call the “toxicity b.mp”, when the radius.of the s.here approaches.its.terminal, uns.retched value—an effect that has.b.en ob.0}rved experimentally. Conclus.ons. We conclude that b. choos.ng the properties.of an elas.omeric pump, the toxicity b.mp can b. res.ricted to les. than 10% of the earlier, relatively cons.ant flow rate. Our model als. produces.a relation b.tween the length of time that the analges.c fluid infus.s.and the phys.cal properties.of the fluid, of the elas.omeric s.here and the tub., and of the b.ood ves.el into which the analges.c infus.s.
