AI Technical Summary

Problems solved by technology

In some systems, one milliliter or more of fluid can be placed in the line, which when pumped at a rate of one milliliter per hour can cause a delay of up to an hour before the drug reaches the patient
These systems may be undesirable in some situations if care is not taken

Embodiment Construction

[0020] The detailed description set forth below describes many different configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. This detailed description includes specific details designed to provide a thorough understanding of the subject technology. Accordingly, dimensions may be provided as non-limiting examples with respect to certain aspects. It will be apparent, however, to one skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.

[0021] It should be understood that the present disclosure includes several examples of the subject technology and does not limit the scope of the appended claims. Various aspects of the subject technology will now be disclosed according to specific but n...

Abstract

Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.

Description

technical field [0001] The present disclosure relates generally to administering medical fluids by infusion, and more particularly to systems and methods for providing and pumping medical fluids. Background technique [0002] Infusion pumps have become a common device in the healthcare industry for the precise administration of intravenous (IV) fluids. Using a pump instead of a raised fluid container with a simple roller clamp to control the flow of IV fluid allows for more accurate and consistent control of the rate of fluid delivery to the patient. [0003] The assembly of tubing, valves, fittings, and needles that connect the fluid containers to the patient may be referred to as an "IV set." IV sets are typically disposable to reduce the risk of infection and contamination. In some infusion pump / IV set systems, the drug to be delivered to the patient is provided at or above the pump. Thus, in these systems, the fluid (such as saline) that fills the line between the pum...
