Linearsystemsofthemediumdrive

The second version used for drawing the media using the peristaltic transfer of the

liquid is represented by the so called linear peristaltic drives. These drives use a linear

peristaltic wave, which drives the medium in the tubing. This linear system is depicted in Fig.

5.6.

As opposed to the rotation systems, these systems are much smaller, while keeping the

same dispensing volume; yet this is compensated for by a more complex internal realization,

and furthermore, these systems require specially designed sets with typed tubing for the given

mechanism, so it is not possible to simply switch the sets, etc. Infusion pump with a linear

system is depicted in Fig. 5.7.
