At least one disc is spaced from and attached to the rotor near the inlet end of the cylindrical housing, so it will rotate with the rotor. A central hole in the (at least one) disc permits fluid to enter the space between the disc and the rotor; it is flung toward the peripheral space between the rotor and the cylindrical housing, where it is subjected to cavitation, and then passed to an outlet. The shaft may pass through one or both of the end walls of the cylindrical housing. The cavitation pump is especially useful for mixing oil field fluids. | 11-19-2015 |
20160059194 | Hydrating and Dissolving Polymers in Salt Solutions - Polyacrylamides, guar gum (sometimes “guar”), xanthan gum, carboxymethylcellulose, hydroxyethylcellulose, and other water-soluble polymers are dissolved and hydrated in salt solutions, including especially recycled drilling, fracturing, and other oilfield fluids having significant salt contents, by passing the water-soluble polymer to an eductor for mixing with the salt-containing solution and then to a cavitation device including an integrated disc pump. The ability to use water-soluble polymers with the salty recycled oilfield fluids has significant environmental benefits, namely (1) fresh water is not needed, (2) disposal of the environmentally undesirable returned fluids is not needed, (3) difficultly degradable synthetic polymers may not be needed, and, in particular, (4) the enhanced ability to use guar, which, being a natural product, is biodegradable, is environmentally favored. | 03-03-2016 |

20110087107 | SPACERS FOR USE WITH AN ULTRASOUND PROBE - A probe cap for use with an ultrasound probe including a head portion and an acoustic surface is disclosed. In one embodiment, the probe cap includes a body that defines a cavity sized for releasably receiving the head portion of the probe therein. The probe cap body further defines a hole that is proximate the acoustic surface of the head portion. A compliant spacer component is disposed in the hole. The spacer component can include a hydrogel and provides an acoustic path between the acoustic surface and a tissue surface of a patient. The spacer component includes a skin contact surface that defines a concavity and is deformable against the tissue surface. | 04-14-2011 |
20110313293 | SUPPORT AND COVER STRUCTURES FOR AN ULTRASOUND PROBE HEAD - A probe cap for use with an ultrasound probe including a head portion and an acoustic surface is disclosed. In one embodiment, the probe cap includes a body that defines a cavity sized for releasably receiving the head portion of the probe therein. The probe cap body further defines a hole that is proximate the acoustic surface of the head portion. A compliant spacer component is disposed in the hole. The spacer component can include a hydrogel and provides an acoustic path between the acoustic surface and a tissue surface of a patient. The spacer component includes a skin contact surface that defines a concavity and is deformable against the tissue surface. Additional embodiments disclose various probe cap and accompanying needle guide designs for use in assisting a clinician with ultrasound probe use and needle insertion into a patient. | 12-22-2011 |
20130338503 | Apparatus and Methods for Detection of a Removable Cap on an Ultrasound Probe - An ultrasound imaging device including the ability to determine when a component, such as a removable probe cap, is attached to a portion of an ultrasound probe. Such a cap is employed in one embodiment to act as a spacer component to provide a standoff for the probe head. Detection of probe cap attachment to the ultrasound probe enables the resultant ultrasound image to be adjusted automatically by the ultrasound imaging system. In one embodiment, an ultrasound imaging system comprises an ultrasound probe, a cap or other component that is attachable to the probe, and a component attachment detection system for detecting attachment of the component to the probe. Once the cap is detected, an aspect of an ultrasound image produced by the imaging system is modified, such as cropping the image to remove undesired portions of the cap, such as the spacer component. | 12-19-2013 |
20140343398 | Bioimpedance-Assisted Placement of a Medical Device - A system and method for guiding a catheter or other medical device to a desired target destination within the vasculature of a patient via bioimpedance measurements is disclosed. The target destination in one embodiment includes placement of the catheter such that a distal tip thereof is disposed proximate the heart, e.g., the junction of the right atrium and superior vena cava. In one embodiment the method for guiding the catheter comprises introducing the catheter into a vessel of the patient, the catheter defining a lumen through which fluids can be infused into the vasculature of the patient. The catheter is advanced toward a target destination within the vasculature. A first impedance value based on intravascular detection of at least one electrical property related to a first tissue surface of the vessel is calculated to enable determination of the proximity of a distal end of the catheter to the target destination. | 11-20-2014 |
