Peristaltic Pumps
نویسنده
چکیده
Peristaltic pumps are mechanical displacement pumps that induce flow in a fluid-filled, flexiblewalled conduit through peristalsis – transport due to traveling contraction waves. While macroscale peristaltic pumps appear in a variety of configurations, micropumps based on this principle almost exclusively use the sequenced contraction and expansion of a small number of discrete actuators – typically three – placed along the fluid channel.

Background: It is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. In the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. Materials and Methods: In this study 60 units of packed red cells were examined before and after p...
متن کاملDesign and Fabrication of a Pump for Peristaltic Flow of variable viscosity fluids
Due to the widespread use of peristaltic pumps in the pharmaceutical industries, manufacturers are searching for new type of pumping machines, based on the mathematical models. Researchers have predicted the results of peristaltic transport in many applications mathematically and failed to interpret the results. One of the reasons is the difficulties faced in generation of peristaltic transport...

Classic methods for delivery of agents to specific organs are technically challenging and causes superfluous stress. The current study describes a method using programmable, implantable peristaltic pumps to chronically deliver drugs in vivo, while allowing animals to remain undisturbed for accurate physiological measurements. In this study, two protocols were used to demonstrate accurate drug d...
متن کاملA Study on Fuzzy Adaptive Control of Enteral Feeding Pump
Recent medical studies have investigated the importance of enteral feeding and the use of feeding pumps for recovering patients unable to feed themselves or gain nourishment and nutrients by natural means. The most of enteral feeding system uses a peristaltic tube pump. A peristaltic pump is a form of positive displacement pump in which a flexible tube is progressively squeezed externally to al...
