Description

Technical Field

[0001] The present disclosure generally relates to intravenous (IV) fluid delivery devices and systems for delivering more than one medical fluid to a patient. More specifically, the present disclosure relates to multi-lumen IV tubing systems that may include a manifold and 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 Technology

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

[0003] The descriptions provided in the background section should not be considered as prior art merely because they are mentioned in or related to the background section. The background section may include information describing one or more aspects of the subject technology. SUMMARY OF THE INVENTION

[0004] In some infusion therapy situations, multiple medications need to be delivered to a patient, thereby using an IV extension set having multiple branches of tubing through which the multiple medications can be dispensed to the patient. For example, a main infusion line can be connected to the patient and multiple branches of tubing via an IV, and any of the multiple branches of tubing can be used by one or more medical personnel to deliver one or more medications to the patient, such as by anesthesiologists and other physicians.

[0005] When delivering medication to a patient via intravenous injection, one or more portions of the IV set may be primed prior to injecting the medication and may be flushed after injecting the medication in order to increase the likelihood that a predetermined volume of medication will be delivered to the patient within a desired time. In some cases, medical personnel must consider the length and volume of the IV set and the tendency of the medication to adhere to or move more slowly against the interior surfaces of the IV set when determining whether the medication was delivered to the patient as intended. In other cases, medical personnel must position themselves very close to the patient to inject the medication directly into the patient's catheter, which may displace or interfere with other medical personnel caring for the patient.

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

[0007] Thus, in some embodiments, there is provided a multi-lumen intravenous tubing system that can include: a multi-lumen tubing including a main lumen and a secondary lumen, both the main lumen and the secondary lumen extending from a first end of the multi-lumen tubing to a second end of the multi-lumen tubing, and the secondary lumen being fluidly separated from the main lumen; and a manifold including a first fluid flow path, a second fluid flow path, a first inlet, a second inlet, and an outlet, the first fluid flow path extending from the first inlet to the outlet, and the second fluid flow path extending from the second inlet to the outlet, wherein the first fluid flow path is fluidly separated from the second fluid flow path, wherein the first end of the multi-lumen tubing is coupled to the outlet of the manifold, and the first fluid flow path is fluidly coupled to the main lumen, and the second fluid flow path is fluidly coupled to the secondary lumen.

[0008] In some embodiments, the multi-lumen intravenous tubing system includes a drug source, a fluid connector, a manifold, and a multi-lumen tubing, the manifold including a first fluid flow path extending from a first inlet of the manifold to the outlet and a second fluid flow path extending from a second inlet to the outlet, wherein the first inlet is fluidly coupled to the drug source, and the multi-lumen tubing includes a first end, a second end, a main lumen, and a secondary lumen, the first end being coupled to the outlet of the manifold, the second end being coupled to the fluid connector, and each of the main lumen and the secondary lumen extending from the first end of the multi-lumen tubing to the second end, and wherein a first fluid can move from the drug source through the first fluid flow path of the manifold and the main lumen to the fluid connector, and wherein a second fluid can move from the second fluid flow path through the second fluid flow path and the secondary lumen to the fluid connector.

[0009] In some cases, the present disclosure provides methods for providing a multi-lumen intravenous injection fitting system, the method comprising: providing a manifold including a first fluid flow path extending from a first inlet of the manifold to an outlet of the manifold and a second fluid flow path extending from a second inlet of the manifold to the outlet of the manifold; and providing a multi-lumen fitting including a first end coupled to the outlet of the manifold such that the main lumen of the multi-lumen fitting is fluidly coupled only to the first fluid flow path and the secondary lumen of the multi-lumen fitting is fluidly coupled only to the second fluid flow path.

[0019] 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 may be provided for some aspects as non-limiting examples. However, it will be apparent to those 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 principles of the subject technology.

[0020] It should be understood that the present disclosure includes examples of the subject technology and does not limit the scope of the appended claims. Aspects of the subject technology will now be disclosed in accordance with specific but non-limiting examples. The various embodiments described in the present disclosure may be made in different ways and variations and in accordance with the desired application or implementation.

[0021] According to some embodiments, the present application discloses various features and advantages of a multi-lumen IV tubing set system. The multi-lumen IV tubing set system of the present disclosure is capable of providing effective and safe drug delivery to a patient. The multi-lumen IV tubing set system provides a single multi-lumen tubing and a manifold that can be configured to receive more than one drug and direct the more than one drug to the patient while preventing the mixing of the drugs along the multi-lumen tubing. The multi-lumen IV tubing set system can prevent the mixing of drugs by providing more than one separate fluid flow path from the manifold and through the multi-lumen tubing. For example, more than one fluid flow path of the multi-lumen IV tubing set 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 set system provides rapid or immediate drug delivery to the patient relative to the time required to deliver a drug in a fluid flow path that injects saline into the main line of the IV set.

[0022] In addition, in some embodiments of the present disclosure, a first inlet of the manifold can be coupled to a flush fluid, such as saline, and a second inlet of the manifold can be used to inject a drug into the multi-lumen IV tubing set system, wherein the fluid (e.g., flush fluid) directed through the first inlet and the fluid (e.g., drug) directed through the second inlet are separated by the manifold and the multi-lumen tubing. Accordingly, the flush fluid coupled to the first inlet of the manifold can be used to flush or clean a medical connector (e.g., catheter) at the end of the multi-lumen tubing, thereby preventing the accidental mixing of drugs.

[0023] Figure 1An example of a multi-lumen IV tubing set for a patient is shown. The multi-lumen IV tubing set 100 is coupled to a portion of an IV kit and is configured to direct one or more medications to the patient 10. The multi-lumen IV tubing set 100 may 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.

[0024] 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 may be a device that is coupled to the patient for an infusion treatment. For example, the medical connector 14 may be the catheter 16 itself, or may be coupled to the catheter 16 such that one or more medications directed through the multi-lumen IV tubing set 100 can enter the patient's 10 blood vessels through the catheter.

[0025] Although in Figure 1 the example shown, the first inlet 210 of the manifold is coupled to the medication bag 12, it should be understood that the present disclosure contemplates embodiments where the manifold is not coupled to a medication bag, and / or embodiments where one or more inlets of the manifold are used to inject medications directly into the manifold.

[0026] To allow one or more medications to be injected into the multi-lumen IV tubing set, 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 may include more or fewer than five inlets.

[0027] The manifold 200 includes separate fluid flow paths from each of the more than one inlet to the outlet. For example, the manifold 200 includes separate fluid flow paths from each of the inlets 210, 212, 214, 216, 218 to the outlet 220. At the outlet 220, each fluid flow path is coupled to a lumen of the multi-lumen tubing such that separate fluid flow paths from the manifold 200 to the multi-lumen tubing 110 and along the multi-lumen tubing 110 are maintained.

[0028] To maintain the separate fluid flow paths, the multi-lumen tubing includes more than one lumen, where each lumen extends from the first end 112 of the multi-lumen tubing to the second end 114.

[0029] The lumens extend along the multi-lumen fitting, and each lumen forms a cross-sectional profile. The cross-sectional profile of each lumen is defined transverse to the longitudinal axis between the first end 112 and the second end 114 of the multi-lumen fitting. Additionally, each lumen defines or forms a profile shape. It should be understood that the present disclosure contemplates embodiments in which each lumen has the same profile shape and in which at least one lumen has a profile shape different from 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 each other.

[0030] Referring Figure 2 , a perspective view of the first end 112 of an embodiment of a multi-lumen fitting 111 is shown, the multi-lumen fitting having a main lumen 120 and more than one secondary lumen 122A, 122B, 122C, 122D. The multi-lumen fitting 111 can have any number of secondary lumens and can have a number of main and secondary lumens corresponding to the number of inlets in the manifold 200. For example, the multi-lumen fitting 111 includes five lumens, which can include the main lumen 120 and the secondary lumens 122A, 122B, 122C, 122D.

[0031] Each of the main lumen 120 and the secondary lumens 122A, 122B, 122C, 122D extends from the first end 112 to the second end 114 of the multi-lumen fitting 111, and each of the main lumen 120 and the secondary lumens 122A, 122B, 122C, 122D is fluidly separated from each other to prevent mixing between the fluids directed through each lumen. When an end of the multi-lumen fitting (e.g., the first end 112) is coupled to the outlet 220 of the manifold, each of the main lumen 120 and the secondary lumens 122A, 122B, 122C, 122D is fluidly coupled to a separate fluid flow path of the manifold.

[0032] The multi-lumen fitting 111 can be configured to have the secondary lumens 122A, 122B, 122C, 122D positioned around the main lumen 120 such that the longitudinal main axis defined by the main lumen 120 is parallel or substantially parallel to the longitudinal secondary axes 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 positioned concentrically around the main lumen 120. In any embodiment of the present disclosure, the positioning, orientation, and configuration of the lumens of the multi-lumen fitting can correspond to and be aligned with the positioning, orientation, and configuration of the fluid flow paths at the outlet 220 of the manifold.

[0033] In some embodiments of the present disclosure, the multi-lumen fitting 111 may include an orientation feature 117 configured to provide a reference for coupling the multi-lumen fitting to a manifold such that each lumen of the multi-lumen fitting is fluidly coupled to a fluid flow path of the manifold. For example, the orientation feature 117 may be visually observable, such as a line or symbol along the fitting. The orientation feature 117 may also be a structure or feature that is palpable or recognizable by touching the orientation feature 117. For example, the orientation feature 117 may be a surface of the multi-lumen fitting that is flat relative to an adjacent portion of the outer surface of the multi-lumen fitting. In another example, the orientation feature 117 may be either the first end 112 or the second end 114 of the multi-lumen fitting, which forms a plane that is less than or greater than ninety degrees relative to the longitudinal axis of the multi-lumen fitting. In another example, the orientation feature 117 may be a notch or step formed in the ends of the first end 112 and / or the second end 114 of the multi-lumen fitting.

[0034] Each of the primary lumen and the secondary lumens also defines a volume corresponding to the desired flow rate of each lumen. The volume of each lumen may be determined by the corresponding lumen profile area relative to the length of the fitting. 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 may 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 fitting may have the same volume per unit length of the multi-lumen fitting.

[0035] Referring Figure 2 to the embodiment of the multi-lumen fitting 111 shown, the primary lumen has a circular profile shape and the secondary lumens 122A, 122B, 122C, 122D have an irregular or sector-shaped profile formed between the primary lumen and the outer surface of the multi-lumen fitting. In some embodiments of the multi-lumen fitting, the area of each secondary lumen 122A, 122B, 122C, 122D is greater than the area of the primary lumen 120.

[0036] Now turning Figure 3 to, another embodiment of a multi-lumen fitting 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 substantially equal.

[0037] Figure 4Another embodiment of the multi-lumen fitting 118 is shown, which has a main lumen and auxiliary lumens, each of the main lumen and the auxiliary lumens having a circular profile shape. Although the present disclosure contemplates embodiments in which the multi-lumen fitting may have any number of main lumens and auxiliary lumens, an embodiment of the multi-lumen fitting 118 is shown as having twelve auxiliary lumens 122A, 122B, 122C, 122D, 122E, 122F, 122G, 122H, 122I, 122J, 122K, 122L, which are concentrically positioned around the main lumen 120.

[0038] The multi-lumen fitting 110 of the present disclosure can be coupled to the outlet of the manifold 200 such that each fluid flow path of the manifold is fluidly coupled to a lumen of the multi-lumen fitting 110. The present disclosure contemplates any embodiment of a manifold that includes more than one inlet and outlet, where the fluid flow paths extend from each inlet to the outlet without intersecting each other.

[0039] Reference Figure 5 , an embodiment of the manifold 200 is shown, where the fluid flow paths of the manifold are shown as lines superimposed on the manifold for clarity and easy 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.

[0040] As Figure 6 shown, at the outlet 220, each of the fluid flow paths 240, 242, 244, 246, 248 are positioned adjacent to each other to be fluidly coupled to the corresponding lumen of the multi-lumen fitting, such as Figure 2 the multi-lumen fitting 111 shown.

[0041] In some embodiments of the present disclosure, the manifold can be configured with a first fluid flow path that is fluidly coupled to the 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 with fluid from the first fluid flow path.

[0042] Figure 7An embodiment of a manifold 300 is shown that is configured to selectively allow at least a portion of a fluid moving through a first fluid flow path to move into a second fluid flow path. For clarity and brevity of disclosure, features of the manifold 300 that are similar to those of the manifold 200 are identified with the same reference numerals. The 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.

[0043] In addition, a tertiary fluid flow path 250 extends from the first fluid flow path 240 to each of the second through 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 respective second through fifth flow paths 242, 244, 246, 248 to which it is connected. By fluidly coupling the first fluid flow path 240 to another fluid flow path using the tertiary fluid flow path 250, fluid can be directed through the first fluid flow path 240 to flush and / or perfuse any one of the respective second through fifth flow paths 242, 244, 246, 248 connected thereto.

[0044] In some embodiments, one or more of the tertiary fluid flow paths 250 may also include a valve 260 that can selectively allow or prevent fluid from moving between the first fluid flow path 240 and the respective second through fifth flow paths 242, 244, 246, 248 to which it is connected.

[0045] 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 perfuse the fluid flow paths, and also contemplates that the first inlet 210 can be coupled to a medication source, such as an IV bag, to provide a steady flow of medication through the manifold and the tertiary fluid path 250.

[0046] In any embodiment of the present disclosure, the manifold 200 and the multi-lumen fitting 110 allow for the direct injection of more than one medication into a patient using a single multi-lumen fitting that extends from the manifold to the patient. Thus, the features of the present disclosure provide for the rapid, effective, and safe direct delivery of medications from the inlets of the manifold and through the lumens of the multi-lumen fitting directly connected to the inlet to the patient.
