An example method includes receiving, within a graphical user interface (GUI) of a medical fluid injection system, a selection of a particular user, providing, within the GUI, a display of a plurality of selectable options, each option including at least a respective graphical symbol, wherein each respective graphical symbol comprises a respective non-textual icon that is a graphical representation of a respective anatomical location associated with the medical procedure, each respective anatomical location comprising one of a left coronary artery, a right coronary artery, or a left ventricle and aorta, retrieving one or more customized injection parameters that have respective values customized for the particular user based on one or more preferences of the particular user, and displaying, within the GUI, the one or more customized injection parameters.

Customizable medical fluid injection system and method

An injection system includes a syringe, which preferably includes larger and smaller inner diameters, and a plunger. A wiper sidewall of the plunger defines a cavity, into which a plunger shaft of the system is inserted, for moving the plunger, within the syringe, for fluid injection. The plunger includes a feature for engaging the shaft, and the sidewall preferably includes an expandable-contractible portion, in which the feature is formed. When the plunger is initially mounted within the larger inner diameter of the syringe, the portion of the sidewall is expanded and the feature of the plunger does not operably engage the inserted shaft. When the shaft moves the plunger into the smaller inner diameter of the syringe, the portion of the sidewall contracts and the feature operably engages the shaft. A deformable end wall of the plunger may be spaced apart from a distal terminal end of the inserted shaft.

A disposable fluid connector includes a first single-use tubing component having proximal and distal ends and a second single-use tubing component having proximal and distal ends, where the first single-use tubing component and the second single-use tubing component are each usable only for a single patient procedure. The disposable fluid connector also includes a connection comprising an electrical connector that is configured to electrically connect the connection to both a powered injector and to an external medical device, where the disposable fluid connector comprises a disposable cassette including a portion that is non-removably attached to both the first single-use tubing component and the second single-use tubing component.

One embodiment provides a method of using contextual lighting to assist a user of a medical fluid injection system. In this embodiment, the method includes providing a lighted display in proximity to a component of the injection system during setup of the medical fluid injection system. If the user has properly performed a setup function that is associated with the component of the injection system, the method further comprises providing a first visual indication on the lighted display. If the user has not properly performed the setup function that is associated with the component of the injection system, the method further comprises providing a second visual indication on the lighted display.

A method of removing air from a flow path of a medical fluid injection system is described. An exemplary method performed by the medical fluid injection device includes delivering a first amount of fluid to a fluid flow path, isolating fluid flow along the flow path, forming a vacuum condition upstream of the fluid isolation, re-establishing fluid communications along the flow path, and delivering a second amount of fluid to the flow path.

In general, this disclosure relates to techniques for automatically supplying a pressurizing unit (e.g., syringe) that is used with a powered medical fluid injection device with fluid. An example method performed by the medical fluid injection device includes obtaining operational state information of the medical fluid injection device, wherein the operational state information includes information other than a fluid delivery amount for a subsequent injection procedure. The example method further includes using the operational state information to determine whether the powered medical fluid injection device permits a fluid replenishment operation for the pressurizing unit. If the fluid replenishment operation is permitted, the method further includes automatically supplying the pressurizing unit with an amount of medical fluid. If the device includes multiple pressurizing units, the device may initiate an automatic fluid replenishment procedure for one or more of the pressurizing units during operation.

Automatically supplying a pressurizing unit of a medical injection device with fluid

An apparatus for determining the length of an open or closed-end pipe by measuring the propagation delay of a sound pulse transmitted down the pipe bore. The apparatus includes an acoustic transducer, an acoustic detector and associated circuitry for computing the time required for an acoustic pulse to travel and return the length of a pipe. Electronic circuitry, including a microprocessor, is employed to provide the apparatus with an automatic gain adjustment feature. The gain circuitry increases the amplification until a return pulse of desired amplitude is obtained. The gain is time varying to make the last-to-return signals strongest thereby avoiding false readings from pipe discontinuities. Compensation is made for speed-of-sound variations due to temperature, humidity, and barometric pressure by direct measurement of speed of sound during each length measurement. The open or closed endedness of a pipe is determined by return signal charateristics and a correction factor applied for open-ended pipe.

Sonic pipe length detector

The apparatus includes a housing that is divided into two parallel passages. A fan in one passage causes air from the outside of a building to flow through one of the passages into the building and a fan in the other passage causes air to be exhausted from inside the building to the outside. A flapper valve prevents entrance of air into the building through either passage when the fans are not operating. A series of media disks, two embodiments of which are disclosed, constitute successive stages, picking up heat and/or moisture from one passage and transferring the heat and/or moisture to the other passage as the disks are rotated within recesses formed in stationary separators. A special drive mechanism is utilized for rotating the disks. Provision is also made for spraying the disks in order to clean them and/or to control the humidity within the building.
