Peristaltic pump with hose lying on a support face - works without pressure fluctuations and is suitable for pumping blood

The pump consists of a flexible hose which is supported on a semi-circular surface. The rollers which are pressed against the hose, roll over a circular track, and press the hose against the support surface and are mounted on a rotor which is mounted eccentrically from the radius on which the hose i...

Zusammenfassung:	The pump consists of a flexible hose which is supported on a semi-circular surface. The rollers which are pressed against the hose, roll over a circular track, and press the hose against the support surface and are mounted on a rotor which is mounted eccentrically from the radius on which the hose is supported. The result of this is that the stretch of hose between two compressing rollers becomes gradually shorter, when the rollers move towards the outlet side of the hose, while the pressure of the pumped medium gradually increases. The rotor on which the rollers are mounted can consist of a cross made from tubes in which the roller supports can slide telescopically.
