Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to intravenous (IV) fluid delivery devices and systems for delivering more than one medical fluid to a patient. More particularly, the present disclosure relates to multi-lumen IV tubing systems that can include a manifold and a multi-lumen tubing for directing more than one medical fluid to a patient while keeping each medical fluid separate along the multi-lumen tubing. BACKGROUND

[0002] In the field of infusion therapy, one or more medications can be directed to a patient using an IV set that can include a medication source, an IV tubing, and a medical connector that fluidly couples the IV set with the patient. For example, the medication source can be a fluid container that can include saline and / or a medication, and the medical connector can be a needleless connector, a y-connector, and / or a catheter.

[0003] The description provided in the background section should not be taken as an admission that any of the information provided in the background section is prior art to the present disclosure. The background section can include information that was obtained from public sources, databases, and other sources. SUMMARY

[0004] In some cases of infusion therapy, it is necessary to deliver multiple medications to a patient, and thus a branched IV extension set having multiple tubing branches through which the multiple medications can be dispensed to the patient is used. For example, a primary infusion line can be coupled to the patient and the multiple tubing branches through an intravenous line, and any of the multiple tubing branches can be used by one or more medical personnel, such as by an anesthesiologist and other physicians, to deliver one or more medications to the patient.

[0005] When delivering a medication to a patient through an intravenous line, one or more portions of the IV set can be primed prior to injecting the medication and can be flushed after injecting the medication in order to increase the likelihood that a predetermined volume of the medication is delivered to the patient within a desired time. In some cases, when determining whether the medication is delivered to the patient as intended, the medical personnel must account for the length and volume of the IV set and the tendency of the medication to stick to or move more slowly against the inner surface of the IV set. In other cases, the medical personnel must position themselves in close proximity to the patient in order to inject the medication directly into the patient's catheter, which can cause other medical personnel caring for the patient to move or be disturbed.

[0006] The multi-lumen IV tubing system of the present disclosure can be implemented to ensure that a predetermined volume of medication is delivered to a patient within a desired time, thereby providing a more efficient system that can be configured to receive more than one medication and direct it to the patient without the need for multiple separate IV tubing connections, without the need to inject the medication directly into a catheter port, and without the need to use a bolus or continuous infusion of saline to flush the medication. The multi-lumen IV tubing system of the present disclosure can include a manifold and a multi-lumen tubing connected to the manifold, where the manifold can have more than one inlet port and the multi-lumen tubing can include fluidly separate lumens, and where each inlet port of the manifold is fluidly coupled to a lumen of the multi-lumen tubing.

[0034] 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 can be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. Accordingly, the descriptions set forth regarding some aspects can, in some instances, be repetitive. However, the practice of the subject technology can encompass many aspects, not just those described with reference to the following detailed description. Skilled artisans will recognize that the subject technology can be practiced with variations of the described implementations, and / or using equivalents thereof, without departing from the spirit and scope of the subject technology. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not as restrictive.

[0035] It is to be understood that the present disclosure includes 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, by way of specific but non-limiting examples. The various embodiments described in this disclosure can be implemented in different ways and variations and according to desired applications or implementations.

[0036] According to some embodiments, the present application discloses various features and advantages of a multi-lumen IV tubing system. The multi-lumen IV tubing system of the present disclosure is capable of providing effective and safe drug delivery to a patient. The multi-lumen IV tubing system provides a single multi-lumen tubing and manifold that can be configured to receive more than one drug and direct the more than one drug to the patient while preventing mixing of the drugs along the multi-lumen tubing. The multi-lumen IV tubing system can prevent mixing of the drugs by providing more than one separate fluid flow path from the manifold and through the multi-lumen tubing. For example, the more than one fluid flow path of the multi-lumen IV tubing system can merge at the end of the multi-lumen tubing that is coupled to the patient, such as at a catheter connector. In some aspects, the multi-lumen IV tubing system provides fast or instant drug delivery to the patient relative to the time required to deliver a drug in a fluid flow path of a saline solution injected into a primary line of an IV set.

[0037] Further, in some embodiments of the present disclosure, a first inlet of the manifold can be coupled to a flushing fluid, such as saline, and a second inlet of the manifold can be used to inject a medication into the multi-lumen IV set system, where the fluid directed through the first inlet (e.g., flushing fluid) and the fluid directed through the second inlet (e.g., medication) are separated by the manifold and the multi-lumen tubing. Thus, the flushing fluid coupled to the first inlet of the manifold can be used to flush or clean the medical connector (e.g., catheter) at the end of the multi-lumen tubing, thereby preventing accidental mixing of the medication.

[0038] Figure 1 An example of a multi-lumen IV set system for a patient is shown. The multi-lumen IV set system 100 is coupled to a portion of an IV set and is configured to direct one or more medications to a patient 10. The multi-lumen IV set system 100 can include a multi-lumen tubing 110 and a manifold 200. In the illustrated example, a first inlet 210 of the manifold is fluidly coupled to a medication bag 12, and an outlet 220 of the manifold is fluidly coupled to the multi-lumen tubing 110.

[0039] The multi-lumen tubing 110 includes a first end 112 and a second end 114. The first end 112 of the multi-lumen tubing is coupled to the outlet 220 of the manifold, and the second end 114 of the multi-lumen tubing is coupled to a medical connector 14 at or near the patient 10. The medical connector 14 can be a device coupled to the patient for infusion therapy. For example, the medical connector 14 can be the catheter 16 itself, or can be coupled to the catheter 16 such that one or more medications directed through the multi-lumen IV set system 100 can pass through the catheter into the blood vessels of the patient 10.

[0040] Although in the illustrated example the first inlet 210 of the manifold is coupled to the medication bag 12, it should be understood that the present disclosure contemplates embodiments in which the manifold is not coupled to a medication bag, and / or embodiments in which one or more inlets of the manifold are used to inject a medication directly into the manifold. Figure 1 Although in the illustrated example the first inlet 210 of the manifold is coupled to the medication bag 12, it should be understood that the present disclosure contemplates embodiments in which the manifold is not coupled to a medication bag, and / or embodiments in which one or more inlets of the manifold are used to inject a medication directly into the manifold.

[0041] To allow for injection of one or more medications into the multi-lumen IV set system, the manifold includes more than one inlet, such as a second inlet 212, a third inlet 214, a fourth inlet 216, and a fifth inlet 218. In another embodiment of the present disclosure, the manifold can include more or less than five inlets.

[0042] Manifold 200 includes separate fluid flow paths from each of the one or more inlets to the outlet. For example, manifold 200 includes separate fluid flow paths from each of inlets 210, 212, 214, 216, 218 to outlet 220. At outlet 220, each fluid flow path is coupled to a lumen of the multi-lumen tube such that the separate fluid flow paths from manifold 200 to and along multi-lumen tube 110 are maintained.

[0043] To maintain the separate fluid flow paths, the multi-lumen tube includes one or more lumens, where each lumen extends from a first end 112 to a second end 114 of the multi-lumen tube.

[0044] The lumens extend along the multi-lumen tube, and each lumen forms a cross-sectional profile. The cross-sectional profile of each lumen is defined transverse to a longitudinal axis between the first end 112 and the second end 114 of the multi-lumen tube. Further, each lumen defines or forms a profile shape. It should be understood that the present disclosure contemplates embodiments where each lumen has the same profile shape, and where at least one lumen has a different profile shape than the other lumens. It is also contemplated that the lumens can be oriented between the first end 112 and the second end 114 such that the longitudinal axes of each lumen are parallel to one another.

[0045] Referring to Figure 2 , a perspective view of a first end 112 of an embodiment of a multi-lumen tube 111 is shown having a primary lumen 120 and one or more secondary lumens 122A, 122B, 122C, 122D. Multi-lumen tube 111 can have any number of secondary lumens, and can have a number of primary and secondary lumens corresponding to the number of inlets in manifold 200. For example, multi-lumen tube 111 includes five lumens, which can include primary lumen 120 and secondary lumens 122A, 122B, 122C, 122D.

[0046] Each of primary lumen 120 and secondary lumens 122A, 122B, 122C, 122D extends from the first end 112 to the second end 114 of multi-lumen tube 111, and each of primary lumen 120 and secondary lumens 122A, 122B, 122C, 122D is fluidically separated from one another to prevent mixing between fluids directed through each lumen. When an end of the multi-lumen tube (e.g., first end 112) is coupled to an outlet 220 of a manifold, each of primary lumen 120 and secondary lumens 122A, 122B, 122C, 122D is fluidically coupled to a separate fluid flow path of the manifold.

[0047] The multi-lumen tube 111 can be configured to have the secondary lumens 122A, 122B, 122C, 122D positioned around the primary lumen 120 such that a longitudinal primary axis defined by the primary lumen 120 is parallel or substantially parallel to a longitudinal secondary axis defined by each of the secondary lumens 122A, 122B, 122C, 122D. In some embodiments of the present disclosure, the secondary lumens 122A, 122B, 122C, 122D are concentrically positioned around the primary lumen 120. In any embodiment of the present disclosure, the positioning, orientation, and configuration of the lumens of the multi-lumen tube can correspond to and align with the positioning, orientation, and configuration of the fluid flow paths at the outlet 220 of the manifold.

[0048] In some embodiments of the present disclosure, the multi-lumen tube 111 can include an orientation feature 117 configured to provide a reference for coupling the multi-lumen tube with the manifold such that each lumen of the multi-lumen tube is fluidly coupled with a fluid flow path of the manifold. For example, the orientation feature 117 can be visually observed, such as a line or symbol along the tube. The orientation feature 117 can also be a structure or feature that is felt or identifiable by touch of the orientation feature 117. For example, the orientation feature 117 can be a surface of the multi-lumen tube that is flat relative to an adjacent portion of the outer surface of the multi-lumen tube. In another example, the orientation feature 117 can be any of the first end 112 or the second end 114 of the multi-lumen tube that forms a plane that is less than or greater than ninety degrees relative to the longitudinal axis of the multi-lumen tube. In another example, the orientation feature 117 can be a notch or step formed in the end of the first end 112 and / or the second end 114 of the multi-lumen tube.

[0049] Each of the primary and secondary lumens also defines a volume corresponding to a desired flow rate for each lumen. The volume of each lumen can be determined by a respective lumen profile area relative to the length of the tube. In embodiments where each lumen has the same profile area, the volume of each lumen will be approximately equal. In some embodiments, when one or more lumens have a different profile shape than the other lumens, each lumen can have a substantially equal volume when the profile area of each lumen is approximately equal. Thus, when the profile area of each lumen is equal, the multi-lumen tube can have the same volume per length of the multi-lumen tube.

[0050] Referring to Figure 2The illustrated embodiment of the multi-lumen tube 111, the primary lumen has a circular profile shape, and the secondary lumens 122A, 122B, 122C, 122D have an irregular or scalloped profile formed between the primary lumen and the outer surface of the multi-lumen tube. In some embodiments of the multi-lumen tube, the area of each secondary lumen 122A, 122B, 122C, 122D is greater than the area of the primary lumen 120.

[0051] Turning now to Figure 3 , another embodiment of a multi-lumen tube 116 is shown having a primary lumen 120 and eight secondary lumens 122A, 122B, 122C, 122D, 122E, 122F, 122G, 122H. Although the primary lumen 120 has a different shape profile than the secondary lumens 122A, 122B, 122C, 122D, 122E, 122F, 122G, 122H, the profile area of each lumen is approximately equal.

[0052] Figure 4 Another embodiment of a multi-lumen tube 118 is shown having a primary lumen and secondary lumens, each having a circular profile shape. Although the present disclosure contemplates embodiments of multi-lumen tubes that can have any number of primary and secondary lumens, the embodiment of the multi-lumen tube 118 is shown having twelve secondary lumens 122A, 122B, 122C, 122D, 122E, 122F, 122G, 122H, 122I, 122J, 122K, 122L positioned concentrically around the primary lumen 120.

[0053] The multi-lumen tube 110 of the present disclosure can be coupled with an outlet of a manifold 200 such that each fluid flow path of the manifold is fluidically coupled with a lumen of the multi-lumen tube 110. The present disclosure contemplates any embodiment of a manifold including more than one inlet and an outlet, where the fluid flow paths extend from each inlet to the outlet without intersecting one another.

[0054] Referring to Figure 5 , an embodiment of a manifold 200 is shown in which the fluid flow paths of the manifold are shown as lines superimposed on the manifold for clarity and ease of reference in the present disclosure. The manifold 200 includes a first inlet 210, a second inlet 212, a third inlet 214, a fourth inlet 216, a fifth inlet 218, and an outlet 220. A first fluid flow path 240 extends from the first inlet 210 to the outlet 220, a second fluid flow path 242 extends from the second inlet 212 to the outlet 220, a third fluid flow path 244 extends from the third inlet 214 to the outlet 220, a fourth fluid flow path 246 extends from the fourth inlet 216 to the outlet 220, and a fifth fluid flow path 248 extends from the fifth inlet 218 to the outlet 220.

[0055] like Figure 6 As shown, at outlet 220, each of the fluid flow paths 240, 242, 244, 246, and 248 is positioned adjacent to each other to fluidly connect with the corresponding cavity of the multi-lumen fitting, for example... Figure 2 The multi-lumen fitting 111 shown.

[0056] In some embodiments of this disclosure, the manifold may be configured with a first fluid flow path fluidly connected to an outlet and a second fluid flow path to allow at least a portion of the fluid moving through the first fluid flow path to move into the second fluid flow path. By allowing at least a portion of the fluid moving through the first fluid flow path to move into the second fluid flow path of the manifold, the second fluid flow path can be flushed by fluid from the first fluid flow path.

[0057] Figure 7 An embodiment of a manifold 300 is shown, configured to selectively allow at least a portion of fluid moving through a first fluid flow path to move into a second fluid flow path. For clarity and brevity, features similar to those of manifold 200 in manifold 300 are identified by the same reference numerals. Manifold 300 includes a first inlet 210, a second inlet 212, a third inlet 214, a fourth inlet 216, a fifth inlet 218, and an outlet 220. A first fluid flow path 240 extends from the first inlet 210 to the outlet 220, a second fluid flow path 242 extends from the second inlet 212 to the outlet 220, a third fluid flow path 244 extends from the third inlet 214 to the outlet 220, a fourth fluid flow path 246 extends from the fourth inlet 216 to the outlet 220, and a fifth fluid flow path 248 extends from the fifth inlet 218 to the outlet 220.

[0058] Furthermore, the tertiary fluid flow path 250 extends from the first fluid flow path 240 to each of the second to fifth flow paths 242, 244, 246, 248. The tertiary fluid flow path 250 allows at least a portion of the fluid moving through the first fluid flow path 140 to move into the corresponding second to fifth flow paths 242, 244, 246, 248 connected thereto. By using the tertiary fluid flow path 250 to fluidly connect the first fluid flow path 240 to another fluid flow path, fluid can be directed through the first fluid flow path 240 to flush and / or infuse any of the corresponding second to fifth flow paths 242, 244, 246, 248 connected thereto.

[0059] In some embodiments, the one or more tertiary fluid flow paths 250 can also include a valve 260 that can selectively allow or prevent movement of fluid between the first fluid flow path 240 and the respective second to fifth flow paths 242, 244, 246, 248 connected thereto.

[0060] The present disclosure contemplates that the first inlet 210 can be used to inject a dose of medication into the manifold 300 to flush or prime the fluid flow paths, and further contemplates that the first inlet 210 can be coupled to a source of medication, such as an IV bag, to provide a steady flow of medication through the manifold and tertiary fluid paths 250.

[0061] In any embodiment of the present disclosure, the manifold 200 and multi-lumen tubing 110 allow for the direct injection of more than one medication into a patient using a single multi-lumen tubing extending from the manifold to the patient. Accordingly, features of the present disclosure provide for the rapid, efficient, and safe direct delivery of medication to a patient from an inlet of the manifold and through a lumen of the multi-lumen tubing directly connected to the inlet.

[0090] No element of any claim is intended to be dependent on another except where explicitly recited in the claim. For example, the phrase "comprising A and B" is intended to mean A or B or both A and B. Further, to the extent that any meaning or definition of a term in this document conflicts with the meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.

[0091] The title, background, brief summary, abstract, and drawings of the present disclosure are hereby incorporated into this disclosure and provided as illustrative examples only, and are not intended to limit the scope or meaning of the claims. It is understood that they will not be used to limit the scope or meaning of the claims at the time of issuance of this application. Furthermore, in the detailed description, it can be seen that the description provides illustrative examples and uses various applications together in the interests of conciseness and with the intent that each such feature can be employed independently of all other features in various embodiments. The methods of this disclosure are not to be interpreted, as reflecting the intent of the claimed subject matter to require more features than are expressly recited in each claim. Rather, as the appended claims reflect, the claimed subject matter lies in less than all features of a single disclosed configuration or operation. The claims are hereby incorporated into the detailed description, where each claim stands as a separate claimed subject matter.

[0092] The claims are not intended to be limited to the aspects described herein, but are to be accorded the full scope consistent with the language claims, and to encompass all legal equivalents thereof. Nonetheless, no claim is intended to be construed as covering unspecific subject matter failing to meet the requirements of 35 U.S.C. §§ 101, 102, or 103, nor should they be interpreted as such.
