Fluid delivery system

摘要

To avoid contamination of workspaces by splashing and the like of a waste fluid. A fluid delivery system for delivering a fluid from one container to another container includes: a delivery channel connecting between the one container to the other container; and a delivery pump which feeds the fluid into the delivery channel by compressively deforming inner diameter in the middle of the delivery channel, wherein the delivery channel is a partially elastic configuration that can be compressively deformed by the delivery pump, and also is a closed-system configuration with which the fluid flowing inside thereof is isolated from outside. As described, the delivery pump and the delivery tube or the waste-fluid container are not directly connected but are simply in contact. Therefore, it is possible to prevent splashing and the like of the waste fluid onto a work space when handling the waste fluid.

1. A fluid delivery system for delivering a fluid from one container to another container, the fluid delivery system comprising:
a delivery channel connecting between the one container to the other container, the fluid being transferred inside of the delivery channel; and a delivery pump that is configured with:
a rotation member that rotates around a shaft;a plurality of rollers that are provided at an outer peripheral edge of the rotation member; anda support member that faces the rotation member and at least one of the plurality of rollers so as to sandwich the delivery channel with the one of the plurality of rollers, the support member being configured with first, second, and third planar surfaces that are continuously connected to each other so that the second planar surface is located between the first and third planar surfaces,wherein the fluid is transferred via the delivery channel by compressively deforming an inner diameter of the delivery channel by the plurality of rollers, wherein the delivery channel is partially elastic, and the delivery channel forms a closed-system with the fluid flowing inside thereof between the one container and the another container and is isolated from outside, when the one of the plurality of rollers is adjacent to the first planar surface, a first gap exists between the one of the plurality of rollers and the first planar surface, when the one of the plurality of rollers is adjacent to the second planar surface, a second gap exists between the one of the plurality of rollers and the second planar surface, and the first gap is smaller than the second gap.
