A method and apparatus provides for configuring the backlight brightness level. The backlight brightness level can be configured at the drug library and/or at the medical device, thereby improving the flexibility a user has in changing backlight parameters. A method and apparatus for managing a power saving mode allows the user to configure the power saving program at the drug library and/or at the medical device.

Infusion pump with configurable screen settings

A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

A method and system is disclosed for operating a medical device with or without a cassette in place. A method is disclosed for adding additional VTBI to an ongoing infusion without stopping the infusion and with maintaining the infusion parameters. A method and system is disclosed for changing the CCA without having to interrupt or completely stop an ongoing infusion. Quick titration buttons are provided to allow improved navigation between various delivery display screens.

User interface improvements for medical devices

A syringe holder includes a body with a syringe retainer, an elongated finger and a stop member connected to the body. The finger inserts longitudinally into a socket on a pump without the aid of tools and permits the holder to move in multiple planes. The stop member limits such movement. The stop member can include a clip for releasably clamping onto a portion of a pump. The syringe retainer can include a hole in the body and may optionally include an adaptor mounted in or extending into the hole for detachably attaching a syringe. The syringe holder can be incorporated into a tube set assembly or an infusion system.

Syringe holding system

A system and method of varying the flow rate of fluid from a medical pump through tubing includes determining an inner diameter of the tubing and fluid flow velocity of fluid in the tubing with a controller based on acoustic signals received by a capacitive micromachined ultrasonic transducer sensor system and then determining and adjusting a fluid flow rate of fluid in the tubing with the controller. In addition, the same sensor system also detects air bubbles in the fluid in the tubing.

A disposable assembly for use with a sensor assembly comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned in the fluid flow passage between the inlet and the outlet. The membrane is located between the lid and base portions along the fluid flow passage. A reinforcing structure, such as a ring or a rigid disk, is positioned between the fluid pressure membrane and the lid portion to provide increased resistance to pressure in the fluid flow passage. The ring or disk can be a separate component or formed on the membrane. The membrane thickness adjacent to sensor access openings in the lid portion can be increased for pressure resistance, too.

Cassette for use in a medication delivery flow sensor assembly and method of making the same

A fluid delivery device such as a cassette removably disposed in a medical pump to control fluid flow in the medical pump. The fluid delivery device has an elongated main body including an inlet, an outlet, and a fluid passage extending from the inlet to the outlet. A flow stop is pivotally mounted to the main body for selectively allowing and stopping fluid flow from the fluid passage to the outlet. The fluid delivery device can have various features including the flow stop having grooved sections, a T-shaped collar on the main body inlet or a flange on the main body to prevent inadvertent engagement of the flow stop during removal of the fluid delivery device from the medical pump.

A point of care fluid testing system for determining properties of a fluid comprises a patient connection, a primary fluid routing portion, a pump, a secondary fluid routing portion, and a flushing fluid connection. The patient connection connects the system to a patient. The primary fluid routing portion has a pump region, a fluid transfer region, and an in-line testing region. The pump region pumps the fluid sample from the patient to the testing portion and back to the patient. The in-line testing region evaluates a first characteristic of the fluid sample. The fluid transfer region transmits a portion of the fluid sample out of the primary fluid routing portion. The secondary fluid routing portion includes an off-line testing portion that receives the portion of the fluid sample transmitted from the fluid transfer region. The off-line testing portion evaluates a second characteristic of the fluid sample.

A differential pressure based flow sensor assembly and method of using the same to determine the rate of fluid flow in a fluid system. The sensor assembly comprises a disposable portion, and a reusable portion. A flow restricting element is positioned along a fluid flow passage between an inlet and an outlet. The disposable portion further has an upstream fluid pressure membrane and a downstream fluid pressure membrane. The reusable portion has an upstream fluid pressure sensor and a downstream fluid pressure sensor. The upstream fluid pressure sensor senses the upstream fluid pressure at a location within the fluid flow passage between the inlet and the flow restricting element. The downstream fluid pressure sensor senses the downstream fluid pressure at a location within the fluid flow passage between the flow restricting element and the outlet. The process utilizes output of the sensors to calculate the flow rate of the fluid.

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.

System for reducing air bubbles in a fluid delivery line

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.

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.
