Some embodiments of an infusion pump device may include a drive system that accurately and incrementally dispenses fluid from the pump device in a controlled manner. Particular embodiments of the drive system may include a rotational motor that is coupled to a string member, which is used to adjust a pawl relative to a ratchet body. In such circumstances, the drive system can provide a reliable and compact infusion pump device that accurately dispenses the desired volume of fluid.

Dispensing fluid from an infusion pump system

Some embodiments of a medical infusion pump system include a pump device having a cap device that mates with a pump housing to retain a medicine cartridge therein. In addition to retaining the medicine cartridge in the pump housing, the cap device may perform a number of preparatory functions or safety functions. In addition or in the alternative, some embodiments of the pump device may include a drive system that advances a piston rod to dispense medicine to the patient in a safe and energy efficient manner.

Operating an infusion pump system

Some embodiments of a medical infusion pump system include a pump device having a flexible pushrod that can adjust from a curved configuration to a generally straight configuration. The flexible pushrod is part of a drive system of the pump device so that the flexible pushrod can be controllably and incrementally advanced toward a medicine reservoir to incrementally dispense the medicine therein. In particular embodiments, the flexible pushrod may comprise an anti-rotation mechanism, an anti-torsion mechanism, or a combination thereof.

Some embodiments of an infusion pump system include a controller device that is configured to removably attach to a pump device in a manner that provides a secure fitting, an overall compact size, and a reliable electrical connection. In particular embodiments, the controller device can be secured to the pump device in a generally side-by-side arrangement. The compact size can enhance discreteness and portability of the infusion pump system.

Removable controller for an infusion pump

Some embodiments of a medical infusion pump system include a pump device and a removable controller device. When the pump device and the removable controller device are removably attached to one another, the components may provide a portable infusion pump unit to dispense medicine to a user. In particular embodiments, the removable controller device includes a user interface to readily provide information, for example, about the operation of the pump.

Some embodiments of an infusion pump system may include a construction that is resistant to external contaminants, such as precipitation, water splashes, sweat and the like. In particular embodiments, the infusion pump system can include a pump device that is removably attached to a controller device to provide an electrical connection therebetween. In such circumstances, the infusion pump system can be assembled as a sealed construction that protects the electrical connection between the pump device and the removable controller device.
