Problems solved by technology

While various LVPs have been used in medical settings for many years, these devices and their associated peristaltic drive components may have limitations in their efficient, effective, and safe use
In particular, while some arrangements are commonly made to detect undesired obstructions to prescribed infusate flow from the LVP, such as by kinked or otherwise accidentally clogged tubing, these arrangements often have the following undesired effects: Inadvertently delivering large volumes of infusate when occlusion is released and / or increased fluid pressure upstream of pumping components exceeds maximum safety line / component pressure limit

Embodiment Construction

[0022] figure 1 It is a schematic perspective view of an exemplary embodiment of a peristaltic infusion pump system 100 for a patient, and a peristaltic infusion pump system 100 includes a peristaltic pump 102 (more specifically, LVP pump 102) and a disposable application kit 104, a kit 104 Target structure and configured to be capable of being operable and removably coupled to pump 102. The application kit 104 is schematically illustrated to provide a fluid path from the intravenous injection bag 106 to the infusion kit or tube 108, and the infusion kit or tube 108 finally delivers the infusion liquid to the patient 110. exist figure 1 In the case where the receiving department 112 of the peristaltic pump 102 is shown to be in a closed configuration, and the applicator 104 is illustrated as not coupled to the pump 102.

[0023] In order to more fully illustrate various components of pump 102, Figure 2A and Figure 2B A portion of the pump 102 is shown. Specifically, only the port...

Abstract

A method of adjusting the pressure profile within an administration kit to minimize the unintentional delivery of large doses of infusion fluid upon sudden release of an occlusion while ensuring that the maximum safety pressure limit of the administration kit is not exceeded.

Description

[0001] Cross-reference related application [0002] The present application claims priority to US Provisional Application No. 62 / 892,707, filed on August 28, 2019, which is hereby incorporated by reference. Technical field [0003] The present disclosure generally relates to infusion pump systems, and more particularly to systems and methods for reduced dose reduction after blocking of large volume pumps (LVP) and infusion pump application kits. Background technique [0004] Various types of infusion pumps have been used to manage the patient delivery and allocate a predetermined amount or dose of a drug, fluid, fluid substance or agent (herein, collectively referred to as "infusion"). The infusion pump provides a significant advantage of manual administration by precise delivery of infusion over the extended period of time. The infusion pump is particularly suitable for diseases and conditions that require regular pharmacological intervention, including cancer, diabetes, and va...
