| 20080312594 | VACUUM SURGE SUPPRESSOR FOR SURGICAL ASPIRATION SYSTEMS - An apparatus and method to suppress vacuum surges in a surgical aspiration system is disclosed and claimed. A vacuum surge suppressor includes a first fluid path for coupling to a surgical instrument, and a filter attached to the first fluid path. A flow restrictor is coupled to the filter with the filter disposed upstream of the flow restrictor. The vacuum surge suppressor also includes a second fluid path for coupling to a vacuum pump. The second fluid path is connected to the flow restrictor and disposed downstream of the flow restrictor. The second fluid path defines a path internal pressure. A third fluid path is coupled to the filter and is connected to the second fluid path, bypassing the flow restrictor. A valve in the third fluid path obstructs flow in the third fluid path in response to the path internal pressure. | 12-18-2008 |
| 20110077596 | Apparatus and Method for Separating and Concentrating Fluids Containing Multiple Components - An apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at various fractions in the apparatus. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. Also selected fractions from the sample can be applied to a patient, either alone or as part of a mixture. | 03-31-2011 |

| 20130310747 | NASAL ASPIRATOR FOR BABIES - A device for suctioning nasal secretions, including a nasal tip having an opening through which the nasal secretions are suctioned, a first pipe, a first end of which is connected to the nasal tip and the other end of which communicates via a first opening, and a second pipe, one end of which communicates via a second opening, and these two pipes form an angle no more than 90°, and the opening connected to the nasal tip is aligned with the second pipe and arranged with the air stream exiting the opening of the second pipe. | 11-21-2013 |
| 20150088069 | Washing Water Spraying Vessel for Nasal Cavity Cleaner - The present invention relates to a washing water spraying vessel for a nasal cavity cleaner. A pumping operation of a pumping member is performed only when a pair of buttons formed on both sides of an outer cap are simultaneously pressed, which allows enabling fundamentally blocking the pumping operation through external pressure unintended by a user, thereby not only preventing washing water from being unnecessarily consumed but also preventing an inner part of the overcap from being contaminated. | 03-26-2015 |
| 20160106965 | Microneedles With Improved Open Channel Cross-Sectional Geometries - In one aspect a drug delivery device may include a reservoir containing a liquid drug formulation and a microneedle assembly in fluid communication with the reservoir. The microneedle assembly may include a plurality of microneedles, with each microneedle defining an open channel for receiving a drug formulation. The open channel may have a normalized hydraulic radius ranging from about 0.1 to about 0.8. The open channel may also have a liquid-to-solid interfacial energy and a liquid-to-vapor interfacial energy when a fixed volume of the drug formulation is received therein. In addition, the drug formulation and a cross-sectional geometry of the open channel may be selected and configured such that the liquid-to-solid energy exceeds the liquid-to-vapor energy as the length of the fixed volume of drug formulation is increased within the open channel. | 04-21-2016 |
