Embodiment Construction

[0028] The detailed description set forth below describes various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. Accordingly, dimensions with respect to certain aspects may be provided as non-limiting examples. 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.

[0029] It should be understood that the present disclosure includes examples of the subject technology and does not limit the scope of the claims. Various aspects of the subject technology will now be disclosed in terms of specific but not limiting examp...

Abstract

A flow controller having an internal tubing is provided. The flow controller may include: an upper housing having a plurality of scales; a lower housing engaged with and slidably coupled to the lower housing; the cavity is defined between the upper shell and the lower shell and used for containing at least one part of the inner pipe fitting. The flow controller may further include a flexible clamp having an upper section mounted in the upper housing and a lower section slidably disposed in the lower housing. The upper and lower housings may be slidably coupled relative to each other to transition the inner tube from (i) an open position in which the lumen of the inner tube is not compressed by the flexible clamp to (ii) a closed position in which the lumen of the tube is at least partially compressed by the flexible clamp.

Description

technical field [0001] The present disclosure relates generally to intravenous (IV) fluid administration, and more particularly to linearly actuated flow controllers for IV fluid administration. Background technique [0002] Intravenous (IV) administration sets (sometimes referred to simply as IV sets) for the infusion of medical fluids typically include a IV tubing. In some cases, gravity infusion of medical fluids uses gravity rather than an infusion pump to deliver the medical fluid through the IV set. Flow rate control through the tubing is typically provided by roller clamps on the IV tubing. However, it is difficult to provide the desired flow rate using roller clamps. Contents of the invention [0003] According to various embodiments of the present disclosure, a flow controller having an internal tubing may include: an upper housing including a plurality of scales; a lower housing engaged with and slidably coupled to the lower housing; and A cavity is defined b...
