20080274654 | ELECTRICAL INTERCONNECTION DEVICES INCORPORATING REDUNDANT CONTACT POINTS FOR REDUCING CAPACITIVE STUBS AND IMPROVED SIGNAL INTEGRITY - An electrical interconnection device for establishing redundant contacts between the ends of two conductive elements to be mated, creating a electrical interconnection without capacitive stubs. | 11-06-2008 |
20090292271 | METHODS AND APPARATUS FOR BUFFERING ANESTHETICS - A device for delivering buffer solution into a buffer cartridge comprises a needle assembly and a pusher. The septa of a buffer cartridge and an anesthetic cartridge are advanced onto a transfer needle, and the pusher advances a plunger into the buffer cartridge to deliver buffer through the transfer needle into the anesthetic cartridge. A separate exhaust needle allows excess anesthetic from the anesthetic cartridge to be exhausted. A compression member is usually provided to maintain a force against the plunger on the buffer cartridge to pressurize and stabilize the contents during sterilization and/or storage. | 11-26-2009 |
20100112829 | Electrical Interconnection Devices Incorporating Redundant Contact Points for Reducing Capacitive Stubs and Improved Signal Integrity - An electrical interconnection device for establishing redundant contacts between the ends of two conductive elements to be mated, creating a electrical interconnection without capacitive stubs. | 05-06-2010 |
20110005958 | METHODS AND SYSTEMS FOR ADJUSTING THE pH OF MEDICAL BUFFERING SOLUTIONS - Buffer solutions within a plurality of containers can be adjusted and controlled by exposing the containers while open to a controlled environment. In particular, an inventory of containers holding bicarbonate buffers can be adjusted to a precisely controlled pH by exposing the containers while open to a controlled carbon dioxide environment in a treatment chamber. | 01-13-2011 |
20110165017 | METHODS AND DEVICES FOR STERILIZING AND HOLDING BUFFERING SOLUTION CARTRIDGES - Trays comprising a base have a plurality of axial slots adapted to receive buffer or other medical solution containers within the slots. A spring or other compression element at the bottom of the slot is configured to engage a plunger at the bottom of the solution container when present in the slot so that pressure is applied to the contents of the container in order to stabilize the contents while the containers are sterilized at an elevated temperature. | 07-07-2011 |
20110166543 | METHODS AND APPARATUS FOR BUFFERING PARENTERAL SOLUTIONS - A system for transferring solutions from a first cartridge into a second cartridge comprises a cartridge holder, a plunger driver, and a cartridge connector. The cartridge connector carries a transfer needle and an exhaust needle. The cartridge holder positions the first cartridge against the cartridge connector so that the transfer needle penetrates the first cartridge septum. The second cartridge is removably inserted into another end of the cartridge connector so that both the transfer needle and the exhaust needle penetrate the second cartridge septum. The plunger driver is disposed to advance a plunger on the first cartridge to transfer solution from the first cartridge into the second cartridge thus displacing solution from the second cartridge through the exhaust needle. The cartridge connector includes a sealed interior waste chamber for receiving the solution from the second cartridge. | 07-07-2011 |
20110247722 | METHOD AND SYSTEMS FOR BUFFERING ANESTHETIC CARTRIDGES WITH BUFFERING SOLUTIONS - An anesthetic cartridge is adapted to receive a volume of buffer by displacing a plunger in one end of the anesthetic cartridge inwardly so that addition of the buffer volume will not displace the plunger excessively beyond the end of the cartridge body. By properly determining the amount of buffer volume required to raise the pH of the anesthetic to a target value, the degree of inward displacement of the plunger can be determined and the cartridge can be used with a system for delivering a precise amount of buffer solution having a known pH into the cartridge to raise its pH, just before the anesthetic is delivered to the patient. | 10-13-2011 |
20110282316 | METHODS FOR BUFFERING MEDICAL SOLUTIONS - A device for delivering buffer solution into a buffer cartridge comprises a needle assembly and a pusher. The septa of a buffer cartridge and an anesthetic cartridge are advanced onto a transfer needle, and the pusher advances a plunger into the buffer cartridge to deliver buffer through the transfer needle into the anesthetic cartridge. A separate exhaust needle allows excess anesthetic from the anesthetic cartridge to be exhausted. A compression member is usually provided to maintain a force against the plunger on the buffer cartridge to pressurize and stabilize the contents during sterilization and/or storage. By delivering a buffer with a precisely controlled pH, accurate buffering of the anesthetic can be achieved. | 11-17-2011 |

20120279179 | METHODS AND APPARATUSES FOR MANUFACTURING A PLURALITY OF CARTRIDGES OF MEDICAL BUFFERING SOLUTION WITH A COMMON PH - The pH of a buffer or other medical solution in a plurality of containers can be adjusted and maintained by partially filling each container with a sodium bicarbonate solution so that a headspace remains over the solution. The headspace is filled with gas having a known CO | 11-08-2012 |
20120291909 | APPARATUS AND METHODS FOR SEQUESTERING FLUIDS EXHAUSTED DURING FLUID TRANSFER - A liquid transfer connector comprises an enclosure holding a transfer needle and an exhaust needle. A container of donor liquid may be attached to an inlet end of the transfer needle and a container holding a recipient liquid may be attached to an outlet end of the transfer needle and an inlet end of an exhaust needle. The exhaust needle has an outlet end within the connector which releases displaced fluid into an absorbent mass which sequesters the fluid to prevent leakage. | 11-22-2012 |
