摘要： In one embodiment, a feed pump of a tube pump type is used for supplying a processing liquid. The tube pump has a squeezing member that moves from a first axial position of a tube at which the squeezing member starts pinching of the tube, to a second axial position at which the squeezing member leaves the tube after feeding the processing liquid toward an ejecting part such as a nozzle. Only one pinched part pinched between the squeezing member and a guide member is formed between the first axial position and the second axial position of the tube, and the only one pinched part moves along the axial direction of the tube, during feeding of a dose of the processing liquid toward the ejecting part.

摘要： A peristaltic pump for pumping a fluid includes a flexible tube and a roller. The flexible tube has inner and outer tubular opposed walls. The inner wall defines a through passage to receive the fluid. The roller has an outer contact surface. The peristaltic pump is configured to compress the flexible tube with the contact surface of the roller to thereby force the fluid through the through passage. At least the contact surface of the roller is formed of borosilicate glass.

摘要： A peristaltic pump includes a driver, a pump body, a hose, a rotor and a connecting member. The driver includes a supporting shaft. The pump body includes a chamber housing the rotor. The hose is assembled to an internal side of a wall of the chamber. The connecting member connects the driver with the rotor, and is received in the chamber. The rotor is configured to sequentially squeeze the hose to cause medium in the hose to flow. The connecting member and the rotor rotate about and are supported by the supporting shaft. The medical peristaltic pump has a simple structure and is easy to operate.

摘要： A peristaltic pump with an oscillating drive 14 and a diverter valve 5, having a cylindrical pump housing 2 and the ports 4 and 12 are arranged in a end wall. The ports 4 and 12 are alternately used as outlet and inlet, controlled by the diverter valve 5 and in dependence on the pivot direction of the pump head 7. The roller or the sliding shoe 8 constantly flattens the pump hose and in this way, forms an annular space that is distinguished into a suction and compression chamber. Due to the constant contact of the roller or the sliding shoe 8, a sudden space enlargement is prevented according to the invention.

摘要： Pump heads for peristaltic pump assemblies are provided. For example, a pump head for a peristaltic pump comprises an occlusion bed, a rotor guide, a rotor assembly positioned between the occlusion bed and the rotor guide, and a pathway for tubing. The pathway comprises an inlet portion, an outlet portion, and a connecting portion that connects the inlet and outlet portions. The inlet portion is defined between the occlusion bed and the rotor guide, the outlet portion is defined between the occlusion bed and the rotor guide, and the connecting portion is defined between the occlusion bed and the rotor assembly. Further, the occlusion bed is movable with respect to the rotor guide and the rotor assembly. In exemplary embodiments, the pump head urges fluid flow through the tubing to supply a cooling fluid to a medical probe assembly for delivering energy to a patient's body.
