20090012448 | FLUID DELIVERY SYSTEM WITH SPIKED CASSETTE - A fluid dispensing machine, such as a peritoneal dialysis or hemodialysis machine, includes a dispenser or cassette that pumps a medical fluid for dialysis or other treatments for patients. The machine includes and uses an autoconnect device for connecting containers of liquid, such as bags of dialysis fluid or medication fluids, to the machine, while maintaining the sterility of the connection. The autoconnect device removes the cap from the fluid bag and pierces a sealing membrane on tubing from the bag. This makes it easier for patients to receive treatment, especially home treatment. The cassettes preferably have tubing ports with integral spikes for piercing the membrane on tubing from bags of liquids. The ports may be staggered for sequential engagement with the spikes. Other embodiments are useful for dispensing other liquids from other types of dispensing or pumping machines. | 01-08-2009 |
20090012449 | FLUID DELIVERY SYSTEM WITH AUTOCONNECT FEATURES - A fluid dispensing machine, such as a peritoneal dialysis or hemodialysis machine, includes a dispenser or cassette that pumps a medical fluid for dialysis or other treatments for patients. The machine includes and uses an autoconnect device for connecting containers of liquid, such as bags of dialysis fluid or medication fluids, to the machine, while maintaining the sterility of the connection. The autoconnect device removes the cap from the fluid bag and pierces the scaling membrane on tubing from the bag. This makes it easier for patients to receive treatment, especially home treatment. Other embodiments are useful for dispensing other liquids from other types of dispensing or pumping machines. | 01-08-2009 |
20090299273 | REMOTE EXCHANGE PERITONEAL DIALYSIS - A portable, flexible peritoneal dialysis system is disclosed. The system includes a flexible harness, such as canvas or cloth, to mount a stiff housing with a heater for holding and heating fresh dialysis fluid. The harness includes straps or other suspending devices for holding a second, flexible housing for a drain bag for holding sent dialysis fluid. The upper portion of the system includes a hook and a load cell for suspending the remaining portions. The load cell is used to measure the weight of the apparatus. By keeping track of the weight and the changes, the quantity of fluid removed from the patient, spent dialysate, is tracked, as is fresh dialysate infused into the patient. An electronics or control portion controls heating of the fresh dialysate, and operation of pumps and valves for moving the dialysate. This portion also includes alarms and communications equipment. | 12-03-2009 |
20110230822 | MEDICAL FLUID MACHINE WITH SUPPLY AUTOCONNECTION - A medical fluid machine with supply autoconnection, the machine comprising: a cassette-receiving wall; a disposable cassette held firmly by the wall, the disposable cassette including a port spike, the port spike fitted with a spike cap; a translating shuttle including a channel sized to hold a portion of a supply tube and including a fixture for releasably holding a supply tube end; a supply tube including an end configured to be releasably held by the fixture of the channel of the translating shuttle, the supply tube fitted with a supply tube cap; a cap removal device selectively positionable between the disposable cassette and the translating shuttle; and a controller programmed to (i) translate the shuttle holding the supply tube at the supply tube end towards the disposable cassette, so that the cap removal device is likewise moved towards the disposable cassette and the spike cap of the disposable cassette is engaged, (ii) translate the shuttle holding the supply tube at the supply tube end away from the disposable cassette and the cap removal device, so that the cap removal device can pull the spike cap off of the port spike and the tube cap off of the tube end, and (iii) translate the shuttle back towards the disposable cassette to allow the port spike of the cassette to spike the tube end. | 09-22-2011 |
20120241367 | DIALYSIS SYSTEM HAVING AUTOCONNECTION - A dialysis system includes a dialysis machine including at least one fluid pump, and an autoconnection mechanism including a moveable holder; a plurality of pierceable connectors each held by the moveable holder of the autoconnection mechanism, each of the pierceable connectors in fluid communication with a source of medical fluid; a plurality of spikes each held fixed by the dialysis machine, each of the spikes in fluid communication with a disposable component that is positioned and arranged to operate with the at least one fluid pump; and wherein the moveable holder is moved automatically by the autoconnection mechanism, so that (i) the spikes pierce the pierceable connectors and (ii) the sources of medical fluid can communicate with the disposable component positioned and arranged to operate with the at least one fluid pump. | 09-27-2012 |
20120271273 | MEDICAL FLUID AUTOCONNECTION AND AUTOIDENTIFICATION METHOD - A medical fluid autoconnection method includes: enabling acceptance a pierceable connector that is capable of fluidly communicating with a source of medical fluid into a moveable holder; temporarily fixing a spike to a medical fluid pumping machine; automatically detecting whether the pierceable connector has been placed into the moveable holder; if the pierceable connector is sensed as being placed in the moveable holder, moving the holder so that the spike pierces the pierceable connector; and enabling medical fluid to be pumped from the source through the connected spiked and connector. | 10-25-2012 |
