  • Patent number: 8317752
    Abstract: A medical pump system includes an input device for entering a command or a value of a pump programming parameter and a memory for storing a programming code. A processor is in communication with the memory and the input device in order to generate a display signal for an output device to generate one of a plurality of screens, such as near view and far view screens. The programming code is operable to display on a far view screen a plurality of medical therapy buttons that can be used to navigate directly to a near view programming screen. The far view screen can also concurrently display quick titration buttons that are associated with the medical therapy buttons and can be used to navigate directly to a quick titration screen without having to go to a general near view delivery screen or near view programming screen.

  • Patent number: 8317698
    Abstract: A method of monitoring performance of a fluid testing system is provided. The method draws a fluid sample to the testing system using a pump. A voltage output of a sensor, such as an optical sensor, is generated. The voltage output of the optical sensor during the drawing is compared to an upper fluid volume drawn based voltage limit and a lower fluid volume drawn based voltage limit stored within a memory. The system is flushed with a flushing fluid using the pump to flush the flushing fluid from the testing system. The voltage output of the optical sensor during the flushing is compared to an upper fluid volume flushed based voltage limit and a lower fluid volume flushed based voltage limit stored within the memory. An alert generates if at least one of the voltage output during the drawing of the fluid sample is outside of voltage limits.

  • Patent number: 8313308
    Abstract: A medical pump with a closed loop stroke feedback system and method, for use with a pumping chamber, for example in a cassette, is disclosed. The pump includes a pumping element that intermittently pressurizes a pumping chamber during a pumping cycle. A pressure sensor detects the pressure exerted by the pumping element on the pumping chamber. A position sensor detects the position of the pumping element. A processing unit processes pressure data from the pressure sensor and position data from the position sensor to determine a calculated stroke volume of the pump for a pump cycle, and to adjust a stroke frequency of the pump to compensate for variation in the stroke volume.

  • Patent number: 8256984
    Abstract: A first portable medical device is adapted for use in an interlocking system for interlocking the first medical device to a second medical device. The first device includes a housing having opposite sides, a selective element, a blocking element, and a clamp mechanism. At least one of the opposite sides includes a matable element to detachably attach a second medical device. The selective element restricts the attachment of the second device to only one side of the first device. The blocking element prevents a third medical device from attaching to the first and second devices once the first and second devices are attached. The clamp restricts the attachment of the second device to only one side of the first device when the clamp is attached to a support member. The clamp permits slide ratcheting axial movement of a clamp shaft.

  • Patent number: 8152486
    Abstract: A medical pump includes a chassis having a fixed seat, and a main carriage having a carriage footing for receiving a fluid delivery device and restricting its movement. An actuator automatically moves the main carriage between open and closed positions to engage the fluid delivery device to the seat. The seat establishes the position of both the main carriage and fluid delivery device in the closed position. The actuator is connected to the main carriage by a rear carriage assembly having a manual release element for disengaging the actuator from rear carriage assembly and thereby from the main carriage. A processing unit detects jam conditions by processing carriage position data and electrical load data from the actuator.

  • Patent number: 8091727
    Abstract: A single-use, clamshell protective cap for use primarily in healthcare settings in order to maintain the integrity of a medication solution. The cap has two halves, a cylindrical skirt, a puncture resistant lid portion, an interior flange, and an interlocking snap. When placed around a flanged injection port such as is found on a conventional fluid container and closed, the lid portion covers an access site on an injection port. After the cap is placed, the interior flange engages the port flange to prevent upward axial movement relative to the port, thereby preventing removal of the cap and thus deterring unwanted or erroneous drug administrations or withdrawals.

  • Patent number: 7981082
    Abstract: A method and pump that accurately senses air in a fluid delivery line pulses or activates and deactivates the air sensor(s) multiple times during the pumping phase of the fluid delivery cycle and can generate alarms based upon a single indication or a cumulative indication of air in the line. The pump can include multiple air sensors spaced along the delivery line so that the method can use the multiple signals therefrom to distinguish real moving air bubbles from false positives and/or air bubbles adhered to the inner wall of the line.

  • Patent number: 7945452
    Abstract: A method and apparatus is disclosed for operating a medical device with a screen having an improved graphical user interface, which selectively reallocates screen display for both single and multi-channel pumps. Channel indicators associate operation information with a specific delivery channel. Patient or drug order verification is facilitated with a rendering of the patient or the entire drug order/label on the screen. Decimal numbers are presented in vertically offset decimal format. A dual function button cancels the current operation and, after a delay, clears entered parameters. An area sensitive scrollbar cycles through information at various speeds. Screen brightness is adjusted based on an ambient light detector. A screen saver mode activates based on several operating conditions. The screen is incorporated in a removable user interface.

  • Patent number: 7905710
    Abstract: A medical pump with an improved continuity low flow delivery system and method for use with a pumping chamber, for example in a cassette, is disclosed. The pump includes a pump drive for exerting a force on the pumping chamber and a sensor for sensing the force/pressure exerted by the pump drive on the pumping chamber. The pump drive position sensor senses the position of the pump drive. The medical pump also includes a processing unit and a memory having a programming code adapted to calculate the rate of change of the sensed force/pressure values and determine whether the rate of change of the sensed force/pressure values meets a rate of change threshold. Once the rate of change threshold is met, the programming code is adapted to calculate a remaining pump drive travel value for determining how much farther the pump drive should travel before the end of an effective pump cycle.
