摘要:
Enables an infusion pump battery capacity management and battery charge alert system and method including an infusion pump with rechargeable batteries, a controller, a computer and a user interface. The infusion pump accepts a programmed infusion and selects a battery capacity assessment option to determine one or more recharge options of the batteries, and may optionally select a program delay option to execute an infusion delay and later select the battery capacity assessment option. During the battery capacity assessment option, the infusion pump calculates an anticipated power capacity requirement to execute the programmed infusion, calculates a remaining battery power capacity, compares the calculated anticipated power capacity requirement to the calculated remaining battery power capacity, and determines whether the infusion pump is able to fully execute the programmed infusion based only on the remaining battery power capacity or whether a recharge is required.
摘要:
A method and system for monitoring and managing a remote infusion regimen where a prescribed infusion regimen is provided and compared to subsequent infusion event data to determine if the data falls within predetermined parameters. If the data does not fall within predetermined parameters a monitoring technician, supportive caregiver, patient or some combination thereof are immediately notified so that corrective action may be taken.

A fluid delivery system having a closed-loop control process for delivering a medical fluid to a patient. A fluid infusion system includes a pump for delivering a fluid to a patient via an administration tube. A flow sensor associated with the administration tube provides an indication of the actual flow rate of fluid in the administration tube. Such a flow sensor may comprise a positive displacement flow sensor constructed using micro-fabrication and/or micro-molding techniques. A reader reads the actual flow rate signal and provides an indication to a controller for controlling the pump. The flow rate information can also be used for providing status information, such as the existence of a blockage in the fluid delivery system.

An apparatus, system and method of programming a medical therapy in a medical device are provided. Generally, the medical device 10 has a controller 12, a memory 14, a processor 16 and an input device 18. The memory 14 is preloaded with at least one of a plurality of patient profiles and condition profiles. The memory 14 is further preloaded with an associated medication therapy for a plurality of the profiles. The input device 18 receives profile data 90, 91 comprising at least one of a patient profile data and a condition profile data for a specific patient, and the processor 16 processes the received profile data 100 and provides as output one of the preloaded medication therapies based on the processed profile data 102.
摘要:
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.

Several filter apparatus employing such a membrane are also disclosed.
摘要:
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.

摘要:
A method of manufacturing a three dimensional structure. In one embodiment, such structures comprise porous structures suitable for implantation in a host. Such a structure preferably exhibits geometric properties that tend to promote vascularization in the area of the structure when implanted into a host. The method includes selectively applying and exposing layers of biocompatible photoimageable material to create layers forming a cross-linked latticework structure having the desired geometric properties. Each layer is formed on top of a prior layer, preferably before any layer is developed. In one form, the structure is manufactured in connection with an implant device and promotes vascularization that supports bioacceptance/biocompatibility of the implant device.
