  • Patent number: 9889253
    Abstract: A dosing unit for an infusion pump device is disclosed having a piston pump with a pump cylinder and a plunger arranged within said cylinder, coaxially arranged along a longitudinal axis. The plunger has a shaft with a thread and the cylinder has a threaded sleeve part with a thread. The two threads engaging with each other in such a way that a rotational movement of the plunger around the longitudinal axis results in an additional linear displacement of the plunger along said longitudinal axis. A separate bias force element biases the two threads in regard to each other along the longitudinal axis, such that the threaded engagement of inner thread and outer thread is free of play independent of a direction of a rotational movement and linear displacement of the plunger in regard to the cylinder.

  • Patent number: 9872956
    Abstract: A method includes receiving data regarding a catheter being used with the infusion device. The catheter has a lumen operably coupled to a reservoir of the infusion device and is configured to deliver fluid from the infusion device to a target location of a patient. The method further includes infusing fluid from the reservoir into the lumen of the catheter at a first rate and monitoring pressure via a pressure sensor in communication with the lumen of the catheter. Monitoring the pressure includes acquiring pressure data from the pressure sensor at a first frequency. The method also includes (i) determining whether the monitored pressure exceeds a first threshold, wherein the first threshold is based on the data regarding the catheter; and (ii) decreasing the rate at which the fluid is delivered from the reservoir into the catheter if the monitored pressure is determined to exceed the threshold.

  • Patent number: 9849232
    Abstract: A fluid flow manager executing on first hardware controls a flow of fluid outputted from a fluid delivery pump to a recipient. A monitor resource, executing on second hardware operating independently of the first hardware, monitors for an occurrence of a failure condition associated with the delivery of fluid. In response to detecting occurrence of a failure condition associated with delivery of the fluid, the monitor resource generates a control output. The control output can be used to perform operations such as discontinue delivery of the fluid, notify a respective caregiver of the delivery failure, etc.

  • Patent number: 9839746
    Abstract: This invention relates to a fluid delivery apparatus, system and method, in particular the use of elastic bands to generate the force required to push fluid out from a container. The fluid that is delivered from the container maybe prefilled and stored prior to its actuation by the elastic band driver or it could be filled just before use. In one embodiment disclosed, a prefilled option would require the user to attach an appropriate extension tubing that acts as a flow control tube to the fluid container which in one embodiment is tubular shaped. In the application where the device is filled just before use, the fluid container that would be engaged with the actuating housing is presented with a fixed rate flow tube. The selection of a particular device configuration replaces the need for programming a flow rate into an electronic syringe pump.

  • Patent number: 9788775
    Abstract: A fluid transfer device for parenterally transferring fluid to and/or from a patient includes a housing, a needle, and an occlusion mechanism. The housing defines a fluid flow path and is couplable to a fluid reservoir. The needle has a distal end portion that is configured to be inserted into the patient and a proximal end portion that is configured to be fluidically coupled to the fluid flow path of the housing, and defines a lumen therebetween. The occlusion mechanism selectively controls a fluid flow between the needle and the fluid flow path. The occlusion mechanism includes an occlusion member that is movable between a first configuration where the lumen of the needle is obstructed during insertion into the patient and a second configuration where the lumen of the needle is unobstructed after the needle has been inserted into the patient allowing fluid transfer to or from the patient.
