BUBBLE TRAP LEVEL CONTROL USING NON-CONTACTING CAPACITANCE PROBES
Systems and methods for non-contact sensing of the level of process fluid within a hygienic bubble trap are contemplated. In particular, it is contemplated that through the use of one or more capacitance probes having their sensor tips placed adjacent to the vessel wall of a hygienic bubble trap, ideally perpendicularly thereto, the fluid level of the process fluid within the hygienic bubble trap may be measured via the circuit of the capacitance probe detecting variances in the electrical field which extends through the vessel wall, as a result of changes in the dielectric as the process fluid rises and falls. In this fashion, the probe is not wetted and is never placed into physical contact with the process fluid, and thus does not need to undergo any clean-in-place or sterilize-in-place processes, greatly simplifying ease of use.
APPARATUS FOR HOLDING A DISPOSABLE MEDICAL ITEM FOR TREATING BLOOD, SYSTEM AND METHOD OF OPERATION
The present invention relates to an apparatus (1) for holding a disposable medical item, in particular a dialyzer (2), plasma filter or adsorbent, for treating blood, a system (10) comprising such an apparatus, and a method for operating a disposable medical item for treating blood. A bearing device (4) is thereby configured to rotatably support the disposable item, and a drive device (5) is thereby configured to rotate the rotatably mounted disposable item around a longitudinal axis (L) extending substantially in a direction in which the blood flows through the disposable item when the disposable item is in operation. Alternatively or additionally, a sensor device (6) is configured to detect a rotation of the rotatably mounted disposable item around at least one rotational axis (L, Q), in particular around the longitudinal axis (L) and/or around a transverse axis (Q) running perpendicular to the longitudinal axis (L) and output corresponding sensor data. A control device (5) is further configured to control the drive device (5) and/or process the sensor data output by the sensor device (6).
Methods and systems for the delivery of dissolved gases and de-gassing medical fluid lines
A method and system for infusing medical liquid with gasses, the system comprising a gas source, a vacuum pump, a temperature-controlled container including a fluid reservoir coupled to the gas source and the vacuum pump, a heating and cooling system, and a sonicator, and a controller configured to de-gas a liquid in the fluid reservoir by activating the vacuum pump, re-gas the liquid in the fluid reservoir by releasing gas from the gas source to the fluid reservoir via a first fluid line, and deliver the re-gassed liquid from the fluid reservoir to a catheter via a second fluid line.
Intravascular Membrane Oxygenator Catheter Systems and Methods
Intravascular membrane oxygenator catheter systems and methods are disclosed, along with methods of making and using the same. A catheter system includes a catheter shaft having a wall that extends from a proximal end to a distal end along a longitudinal axis to define a lumen, a plurality of hollow fiber membrane loops each having a proximal portion positioned within the lumen of the catheter shaft and a distal portion extending beyond the lumen of the catheter shaft, the hollow fiber membrane loops are nonporous with solid walls; a pneumatic source in pneumatic communication with the hollow fiber membrane loops. The pneumatic source provides a gas containing oxygen at a pressure sufficient to cause a diffusive flux of the gas containing oxygen from an interior of the hollow fiber membrane loops to a fluid exterior to the hollow fiber membrane loops in a region of interest of a subject.

Acoustophoretic separation of lipid particles from red blood cells
A system for removing lipids from blood during cardiopulmonary bypass surgery is disclosed. The system uses an acoustophoretic separator having improved trapping force. The transducer of the acoustophoretic seperator includes a ceramic crystal. Blood flows through the separator, and lipids are trapped and removed.
Method of ultrasonic degassing of liquids for dialysis
A device for degassing liquids, in particular liquids used in dialysis, has a degassing unit that includes an ultrasonic unit. Liquids to be degassed are treated in the degassing unit by ultrasound from the ultrasonic unit. Degassed liquids are discharged from the degassing unit through a hollow channel in the ultrasonic unit, and are available for further use.
METHODS AND SYSTEMS FOR THE DELIVERY OF DISSOLVED GASES AND DE-GASSING MEDICAL FLUID LINES
A method and system for infusing medical liquid with gasses, the system comprising a gas source, a vacuum pump, a temperature-controlled container including a fluid reservoir coupled to the gas source and the vacuum pump, a heating and cooling system, and a sonicator, and a controller configured to de-gas a liquid in the fluid reservoir by activating the vacuum pump, re-gas the liquid in the fluid reservoir by releasing gas from the gas source to the fluid reservoir via a first fluid line, and deliver the re-gassed liquid from the fluid reservoir to a catheter via a second fluid line.
Heart deairing system
A device and method for transmitting vibration to the heart during open-heart surgery in order to dislodge air bubbles formed along interior walls of the heart so that they may be removed from the body, rather than allowed to enter the circulatory system.
Blood Treatment Apparatus with Vibration Device
