Intravenous (IV) infusion sets are used in the medical field for inserting liquid substances into a patient. IV infusion sets are typically constructed by joining multiple translucent polymeric tubing segments to multiple polymeric components. IV infusion sets for use with infusion pumps are typically dedicated to infusion pump use as a complete infusion set. Further, a dedicated infusion set is required for each brand and type of infusion pump, where a particular dedicated infusion set is not compatible with any other brand or type of infusion pump. The need to buy and stock multiple different dedicated IV infusion sets results in high costs to the health care industry.
In view of the high costs of dedicated pump infusion sets, a typical work around in the health care industry is to substitute a gravity IV set for use with an infusion pump. However, gravity IV sets are not rated or qualified for use with infusion pumps, resulting in inaccuracies during pump infusion. Gravity IV sets also pose a much higher risk for broken tubing during pump infusion, which may result in patient injury. It is desirable to provide IV infusion sets for infusion pumps with reduced costs and risks.

The disclosure provides various examples of the subject technology, and the subject technology is not limited to these examples. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects.
A reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more. Pronouns in the masculine (e.g., his) include the feminine and neuter gender (e.g., her and its) and vice versa. Headings and subheadings, if any, are used for convenience only and do not limit the invention.
The word “exemplary” is used herein to mean “serving as an example or illustration.” Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. In one aspect, various alternative configurations and operations described herein may be considered to be at least equivalent.
As used herein, the phrase “at least one of” preceding a series of items, with the term “or” to separate any of the items, modifies the list as a whole, rather than each item of the list. The phrase “at least one of” does not require selection of at least one item; rather, the phrase allows a meaning that includes at least one of any one of the items, and/or at least one of any combination of the items, and/or at least one of each of the items. By way of example, the phrase “at least one of A, B, or C” may refer to: only A, only B, or only C; or any combination of A, B, and C.
A phrase such as an “aspect” does not imply that such aspect is essential to the subject technology or that such aspect applies to all configurations of the subject technology. A disclosure relating to an aspect may apply to all configurations, or one or more configurations. An aspect may provide one or more examples. A phrase such as an aspect may refer to one or more aspects and vice versa. A phrase such as an “embodiment” does not imply that such embodiment is essential to the subject technology or that such embodiment applies to all configurations of the subject technology. A disclosure relating to an embodiment may apply to all embodiments, or one or more embodiments. An embodiment may provide one or more examples. A phrase such an embodiment may refer to one or more embodiments and vice versa.
