| 20110270183 | Syringe and Catheter Set Comprising Same - A syringe comprising a clear syringe barrel, a clear hollow plunge which can be pushed and pulled within the syringe barrel and is open at both ends, a gasket having a throughhole for providing communication between the inside of the plunger and the inside of the syringe barrel and provide a fluid tight seal with the syringe barrel, and a return-flow prevention mechanism which allows the fluid flowing into the plunger to flow in an outward direction from the inside of the plunger. | 11-03-2011 |
| 20080269682 | SYSTEMS AND METHODS ALLOWING FOR RESERVOIR AIR BUBBLE MANAGEMENT - Various embodiments of the present invention are directed to limiting a presence of air bubbles in a fluidic medium expelled from a reservoir. In various embodiments, a reservoir is shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir. Also, in various embodiments, a plunger head within a reservoir is shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir. In some embodiments, both a reservoir and a plunger head within the reservoir are shaped so as to limit a presence of air bubbles in a fluidic medium expelled from the reservoir. | 10-30-2008 |
| 20100312185 | DEVICE SUITABLE FOR ADMINISTERING MUTUALLY INCOMPATIBLE LIQUID SUBSTANCES INTO THE HUMAN BODY - An object of the present invention is an apparatus for administering liquids into the human body characterized in that it has at least one main loading channel provided with at least one main administration point able to be connected to at least one container holding the liquid and at least one secondary loading channel, separated from the first by a membrane, provided with at least one container holding the liquid. Such apparatus allows the independent and simultaneous administration of liquids incompatible with each other, into the human body. | 12-09-2010 |
| 20100030151 | DEBUBBLER - A device for removal of a gas from a liquid in a medical infusion line has a housing containing a plurality of hollow fiber membranes. Preferably liquid passes on the exterior of the membranes and gas bubbles in the liquid pass into the lumens of the hollow fiber membranes. This is for removal by a vacuum. The device can include its own vacuum chamber. When the device has its own vacuum chamber, it can include a warning system to alert a user to replace the device when the provided vacuum is no longer sufficient. | 02-04-2010 |
| 20120022449 | FILTER DEVICE AND LIQUID INJECTION APPARATUS HAVING THE SAME - A filter device of the present invention includes a hydrophilic filter located in a vertical space in a filter housing to filter off solid impurities in an introduced liquid, at least one hydrophobic filter located corresponding to at least one gas discharge hole provided in the filter housing, the hydrophobic filter allowing gas in the introduced liquid to be discharged to the outside before and/or after the liquid passes through the hydrophilic filter, and a blocking member for preventing gas in the liquid passing through the hydrophilic filter from flowing into the outlet tube, the blocking member being installed in the filter housing to block the outlet tube, the blocking member having a longitudinal passage formed in a center portion thereof so that the liquid is introduced into the outlet tube through the passage and discharged therefrom. According to the present invention, there are advantages in that the filter device can effectively remove air and impurities such as solid particles contained in a liquid such as a medicine, prevent the air in the medicine from flowing into an extension tube connected to the filter device, and ensure a maximum surface area of a hydrophilic filter for filtering off solid particles such as glass fragments so that a flow rate of a medicine passing through the filter device does not decrease. | 01-26-2012 |
