摘要： A blood pump is disclosed. The blood pump apparatus is arranged to provide pulsatile flow, and comprises a flexible inner cylindrical duct providing a blood flow region, and an outer cylindrical duct arranged to surround the inner cylindrical duct and arranged to accommodate a pumping fluid. In the pump the inner cylindrical duct is described as comprising a blood inlet for receiving blood into the region, a blood outlet for passing blood out from the blood flow region and a passageway therebetween. There is also described the feature of the inner duct comprising a non return valve at the blood inlet and a non return valve at the blood outlet, the outer cylindrical duct having a fluid port for a pumping fluid, and a pump device arranged to cyclically deliver and withdraw pumping fluid to the fluid port thereby cyclically compressing and expanding the flexible inner cylindrical duct urging blood through the blood flow region and delivering a pulsating blood flow through the blood outlet.

摘要： An aspiration system to control vacuum pressure in an ultrasonic surgical handpiece to result in improved control responsiveness during aspiration. The system comprises a console including a vacuum pump. The system includes a cassette comprising a joint that divides a vacuum path into at least two flow paths. A first joint port couples to a first flow path. A second flow path is coupled to a second joint port, a third flow path is coupled to a third joint port, and a fourth flow path is coupled to a port on a surgical waste receiver. A first sensor senses pressure in the fourth flow path and provides a waste receiver pressure signal. A second sensor senses pressure in the third flow path and provides a tip pressure signal. The controller controls a position of a first vent valve and a second vent valve based on the waste receiver pressure signal and the tip pressure signal, respectively.

摘要： A suction control unit placed on an endoscope to control application of suction through at least one of two working channels of the endoscope. The suction unit has first and second valves with first and second valve openings, at a proximal end, that lead through to a distal end, which is adapted to be placed on the first and second ports of the two working channels. The suction unit has a channel extending between the first and second valves, an opening extending from a front wall to a rear wall of the housing and through the channel, and a switcher having a handle and a shaft with a through hole. When the shaft is placed within the opening and in a first position, suction is applied to both the working channels. When the shaft is placed within the opening and in a second position, suction is applied to only one of the two working channels.

摘要： A connector-with-integrated-check-valve for minimizing microbial migration to catheter-tubing is formed from three parts: a connector-for-catheter-tubing that is hollow and with an internal valve seat; an elastomer disc shaped gate; and a connector-for-extension-tubing that is hollow and with support-surfaces. When one end of the connector-for-catheter-tubing is attached to one end of the connector-for-extension-tubing, a pocket is formed where the seat is disposed opposite and facing the support-surfaces; the gate is disposed within this pocket; such that when the gate contacts this seat due to urine backflow (reflux), the connector-with-integrated-check-valve is closed to such urine backflow; and where a remaining end of the connector-for-catheter-tubing is attachable to catheter-tubing; and where a remaining end of the connector-for-extension-tubing is attachable to the extension-tubing, such that there is a continuous urine flow path from the catheter-tubing, to the connector-with-integrated-check-valve when open, and to the extension-tubing.

摘要： Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

摘要： A sealing assembly for a fluid infusion device includes a base plate, a reservoir port receptacle, a flow base component, and a needle sealing element. The receptacle receives the reservoir port, and has proximal and distal ends, and a needle entry in the distal end to receive a hollow needle of a fluid reservoir. The flow base component has an inlet structure defining a fluid chamber, and a needle guide pin protruding therefrom. The end of the guide pin fits within the hollow needle. The needle sealing element has a proximal flange adjacent to the inlet structure, a distal flange opposite the proximal flange, a neck section between the flanges, and a needle opening extending through the neck section. The needle sealing element is positioned within the port receptacle such that the neck section surrounds the end section of the needle guide pin.
