Description

FIELD OF THE INVENTION

The present disclosure generally relates to medication delivery systems and, in particular, to fluid manifolds.

BACKGROUND

Medical treatments often include the infusion of a medical fluid (e.g., a saline solution or a liquid medication) to patients using an intravenous (IV) catheter that is connected though an arrangement of flexible tubing and fittings, commonly referred to as an “IV set,” to a source of fluid. During some medical treatments, more than one medical fluid is delivered to the patient simultaneously. For example, one or more drugs can be introduced into the infusate that is administered to the patient.

In some applications, the administration of multiple medical fluids may be a complex procedure and may result in imprecise administration of certain medical fluids.

DETAILED DESCRIPTION

The disclosed fluid manifold incorporates a valve to control flow from an injection port into the flow channel of the manifold. The valve includes a divider body that is movable within a divider volume to control flow into the flow channel. By utilizing a divider body within a divider volume, the manifold can reduce the “dead volume” of residual medications remaining in the injection port after administration of the medication.

The detailed description set forth below is intended as a description of 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. 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 concepts of the subject technology. Like components are labeled with identical element numbers for ease of understanding. Reference numbers may have letter suffixes appended to indicate separate instances of a common element while being referred to generically by the same number without a suffix letter.

While the following description is directed to the administration of medical fluid using the disclosed manifold, it is to be understood that this description is only an example of usage and does not limit the scope of the claims. Various aspects of the disclosed manifold and manifold array may be used in any application where it is desirable to provide for the administration of medical fluids

The disclosed manifold overcomes several challenges discovered with respect to certain conventional manifolds. One challenge with certain conventional manifolds is that conventional manifolds may have large diameter channels leading to the infusate stream and therefore have a large dead volume where different drug residuals may mix. Further, certain components, such as the channel within the stopcock cannot be flushed. Additionally, certain conventional manifolds can have open ports, which are exposed to the environment when syringes are changed or removed, potentially contaminating the fluid stream. Further, conventional manifolds that utilize twisting stopcocks require the clinician to remember to twist the stopcock to open before administering the drug and then remember to twist the stop cock closed. Because mixing of residual drugs and fluid contamination may have adverse effects on the patient and clinicians may forget to open or close a stopcock, leading to backflow into a syringe, the use of conventional manifolds is undesirable.

Therefore, in accordance with the present disclosure, it is advantageous to provide a fluid manifold as described that reduces the mixing of residual drugs by reducing the dead space of the manifold, avoids fluid contamination by reducing the area exposed to the environment, and isolates the infusate stream from the connected syringes.

An example of a fluid manifold that reduces the mixing of residual drugs, avoids fluid contamination, and isolates the infusate stream is now described.

FIG. 1 is a perspective view of a fluid manifold array 100, in accordance with various aspects of the present disclosure. In the depicted example, the fluid manifold array 100 allows infusate to flow through the fluid manifold array 100.

As illustrated, an infusate stream A or any other stream of medical fluid (e.g. a saline solution, liquid medication, or any combination thereof) can flow through an inlet port 102, through the fluid manifold array 100, and through the outlet port 104 to administer the infusate stream C to the patient. In the depicted example, the fluid manifold array 100 can be assembled or formed from one or more fluid manifolds 110 that are joined or otherwise coupled together. Therefore, the infusate stream A can flow through each of the fluid manifolds 110 forming the fluid manifold array 100 to administer the infusate stream C to the patient.

FIG. 2 is a cross-sectional view of a fluid manifold 110 of the fluid manifold array 100 of FIG. 1 in a resting position. FIG. 3 is a cross-sectional view of a fluid manifold 110 of the fluid manifold array 100 of FIG. 1 in a depressed position. FIG. 4 is an exploded view of a fluid manifold 110 of the fluid manifold array 100 of FIG. 1. With reference to FIGS. 1-4, in some embodiments, each fluid manifold 110 includes a body 109 that defines an inlet port 112 and an outlet port 114. As illustrated, the body 109 can further define a flow channel 118 that allows flow received from the inlet lumen 113 of the inlet port 112 to flow through the flow channel 118 to the outlet lumen 115 of the outlet port 114.

As illustrated in FIG. 1, multiple fluid manifolds 110 can be coupled or daisy-chained together to provide a desired fluid manifold array 100. As can be appreciated, any suitable number of fluid manifolds 110 can be coupled together to provide a desired configuration for the fluid manifold array 100. Optionally, the body 109 of the fluid manifold 110 can define a base portion 111 to facilitate mounting and/or coupling of the fluid manifolds 110 to each other or to a common mounting plate or base.

In the depicted example, an outlet port 114 of a fluid manifold 110 can be coupled to an inlet port 112 of an adjacent fluid manifold 110 to permit flow to be transferred from one fluid manifold 110 to another fluid manifold 110 within the fluid manifold array 100. As can be appreciated, the inlet port 112 of the first fluid manifold 110 can serve as the inlet port 102 of the fluid manifold array 100 and the outlet port 114 of the last fluid manifold 110 can serve as the outlet port 104 of the fluid manifold array 100. Accordingly, the infusate stream A received by the inlet port 102 of the fluid manifold array 100 can pass through the inlet port 112, the flow channel 118, and the outlet port 114 of each fluid manifold 110 of the fluid manifold array 100, and through the outlet port 104 of the fluid manifold array 100 to administer the infusate stream C to the patient.

Any of the ports described below may include any number of sealing devices or configurations. Such sealing devices or configurations may be adapted to allow various devices to be inserted therethrough while also providing a fluid seal around an inserted device.

As can be appreciated, a wide variety of materials may be used in the construction of embodiments such as those disclosed herein. Typical materials may include a polycarbonate for the body 109 of the fluid manifold 110, though any suitable material including, for example, acrylics, polyolefins, engineering polymers, blends and alloys of any of an array of polymers, as well as self-lubricating polymers may be used. Sealing may be accomplished by the use of an interference fit, though alternative methods may be used including the use of elastomeric seals and o-rings. The various components may be assembled using bonding techniques including solvents, UV cured adhesives; welding techniques including ultrasonic, thermal or spin techniques; or snap fits and/or other mechanical attachment devices.

During operation, the fluid manifolds 110 of the fluid manifold array 100 allow for the introduction of a drug stream B or any other stream of medical fluid to be combined with the infusate stream A to be administered to the patient as the combined infusate stream C. In the depicted example, each fluid manifold 110 can allow for a drug stream B to be combined with the infusate stream A flowing therethrough.

As illustrated, each fluid manifold 110 includes an injection port 120 to allow for the introduction of drug stream B into the flow channel 118. In some applications, the injection port 120 can receive a drug stream B from a syringe or other fluid source coupled to the injection port 120. The injection port 120 can define an injection port lumen 121 that allows for flow to be directed toward the flow channel 118. As can be appreciated, the fluid manifold array 100 can include any suitable number of fluid manifolds 110 to provide a desired number of injection ports 120.

Optionally, the injection port 120 can include a sealing member 150 disposed within the injection port lumen 121. The sealing member 150 can seal against the injection port lumen 121 to reduce the exposure of the flow channel 118 and the infusate stream A to the environment, reducing the chance of contamination and/or blood stream infections through the infusate stream C.

During operation, the sealing member 150 can permit the introduction of a syringe or other fluid source into the injection port 120. The sealing member 150 can define a split septum 152 to permit the syringe or other fluid source to be inserted past the sealing member 150. The split septum 152 can seal against the syringe or other fluid source to minimize exposure of the infusate stream A to the environment.

As described herein, the injection port 120 can provide fluid communication between the injection port lumen 121 and the flow channel 118. As illustrated in FIGS. 2 and 3, the flow can pass from the injection port lumen 121 through a divider volume 116 and into the flow channel 118. The divider volume 116 can be defined within the body 109 between the injection port lumen 121 and the flow channel 118.

In some embodiments, fluid flow from the injection port lumen 121 can be introduced into the divider volume 116 via a first injection channel 122. The first injection channel 122 is defined in the body 109 and provides fluid communication between the injection port lumen 121 and the divider volume 116. Fluid flow from the divider volume 116 can be introduced into the flow channel 118 via a second injection channel 117. The second injection channel 117 is defined in the body 109 and provides fluid communication between the divider volume 116 and the flow channel 118.

Therefore, flow from the injection port lumen 121 can flow from the first injection channel 122 to the second injection channel 117 across the divider volume 116. As illustrated, the first injection channel 122 and the second injection channel 117 can be disposed on opposite sides of the divider volume 116. Optionally, the first injection channel 122 and the second injection channel 117 can be aligned within the divider volume 116.

In the depicted example, a valve 130 can control flow from the injection port 120 into the flow channel 118. As illustrated, the valve 130 can include a divider body 134 that is movable within the divider volume 116 to control the flow between the injection port 120 and the flow channel 118. As can be appreciated, the configuration of the divider body 134 within the divider volume 116 can reduce or minimize the dead volume within the divider volume 116, minimizing the mixing of residual drugs introduced into the flow channel 118.

As illustrated in FIG. 2, the valve 130 can restrict or prevent flow from the injection port 120 into the flow channel 118 in a resting or sealing position. As illustrated, in the divider body 134 can block flow from the injection port 120 to the flow channel 118 by covering, sealing, or otherwise obscuring the flow path between the first injection channel 122 and the second injection channel 117. In some embodiments, the divider body 134 restricts or prevents flow from the injection port 120 from entering the divider volume 116, restricting or preventing any residual drugs or fluid from remaining in the divider volume 116.

Optionally, the valve 130 can include a biasing member 140 to urge the valve 130 into the resting or sealing position. During operation, when the valve 130 is not actuated, the biasing member 140 can urge the divider body 134 to the resting or sealing position to restrict or prevent flow between the injection port 120 and the flow channel 118. The biasing member 140 can be a spring or other urging member. Advantageously, the biasing member 140 can restrict or prevent unintentional drug mixing or backflow from a drug or medical fluid being administered in an adjacent injection port 120 by sealing the injection port 120 from the flow channel 118 when the injection port 120 is not in use.

As shown in FIG. 3, the valve 130 can be depressed, actuated, or otherwise moved into an actuated or flow position to allow flow from the injection port 120 into the flow channel 118. In the depicted example, the divider body 134 can define a divider port 136 that allows flow therethrough. Therefore, as illustrated, the divider body 134 can be moved to permit flow from the injection port 120 to the flow channel 118 via the divider port 136. In some embodiments, the divider port 136 is aligned to create a flow path between the first injection channel 122, the divider port 136, and the second injection channel 117. As can be appreciated, the divider body 134 can be moved within the divider volume 116 to permit the divider port 136 to be aligned with the first injection channel 122 and the second injection channel 117 in the flow position. Advantageously, the configuration of the divider port 136 within the divider volume 116 minimizes the dead volume of residual drugs within the fluid manifold 110.

Optionally, the valve 130 can include a button 132 to allow a clinician to move the divider body 134 into the flow position. During operation, the valve 130 can be actuated by pressing the button 132, allowing the clinician to dispense the drug or medical fluid into the flow channel 118 via the injection port 120. During actuation of the valve 130 the biasing member 140 can be compressed or otherwise energized.
