摘要： A peristaltic transport device comprising a tube member having an inner space to receive material, the member includes a series of repeating sections wherein each of the sections includes a plurality of bladders to selectively occlude portions of the inner space according to a defined peristaltic sequence to transport the material through the inner space. An actuator assembly is coupled to the tube member to control the selective occlusion of the inner space by selectively expanding and contracting ones of the plurality of bladders according to the defined peristaltic sequence. The actuator assembly simultaneously controls corresponding ones of the plurality of bladders across the series of repeating sections.

摘要： A safety interlock for use in a medical device having a control system for controlling operation of the medical device includes a central tubular portion defining a fluid passage for passing fluid through the safety interlock. An outer ring portion is adapted for mounting the safety interlock in the medical device. A spoked connector portion connects the central tubular portion to the outer ring portion so that the outer ring portion is spaced radially outwardly from the central tubular portion in opposed relation with at least a portion of the central tubular portion. The safety interlock is adapted for mounting in the medical device in a path of electromagnetic radiation from a source of electromagnetic radiation such that the central tubular portion reflects the electromagnetic radiation to a electromagnetic radiation detector when properly loaded on the medical device.

摘要： A peristaltic pump having controlled suction. In one embodiment, the pump includes a tubing which is collapsed when the internal pressure of the tubing is equal to or less than ambient. In this state, the pump is unable to generate negative pressures. An air-tight housing may be provided over the tubing and connected to a vacuum source. Upon a vacuum being applied, the tubing is capable of controllably producing negative pressures, allowing the pump to be operated as a suction pump. In another embodiment the tubing exhibits a variable cross-sectional width.

摘要： A self-regulating peristaltic pump having a pumping chamber of enhanced operating life. The operating life of the tubing is improved by a combination of features including providing the tubing with a naturally collapsed passageway. The tubing is collapsed when the internal pressure of the tubing is equal to or less than ambient. In this state, the pump is unable to generate negative pressures. Upon fluid being supplied to the tubing at a pressure greater than ambient, the tubing inflates and cooperates with rollers of the pump to transmit the fluid. The pump also includes a novel means for adjusting and regulating the tension of the tubing further enhancing the operating life of the tubing.

摘要： A linear cleaning peristaltic metering pump includes a pump body, a hose fixing accessory and an anti-backflow accessory. The hose fixing accessory is configured for arranging a working hose. The anti-backflow accessory is configured for clamping and loosening the working hose. The pump body is configured for performing reciprocating motion to clamp or loosen the working hose, thereby realizing a pumping effect by metering pump. The anti-backflow accessory is in cooperation with the pump body. The pump body comprises a roller lifting assembly, a roller hose-pressing assembly, a pump body outer cover assembly and a power transmission part. The power transmission part is configured for driving the roller lifting assembly to perform lifting linear motion, thereby driving the roller hose-pressing assembly to move and to clamp or loosen the working hose.
