The present disclosure generally relates to drug delivery systems and methods. More particularly, the present disclosure relates to improved approaches for preparing and delivering dosing systems.
Drugs are administered to treat a variety of conditions and diseases. Intravenous (“IV”) therapy is a drug dosing process that delivers drugs directly into a patient's vein using an infusion contained in a container (e.g., a pliable bag). These processes may be performed in a healthcare facility, or in some instances, at remote locations such as a patient's home. A disposable IV pump in the form of an elasticized balloon may be used in an at-home setting to provide patients the ability to administer their own dosages. These take-home systems typically lack programming, are offered in a range of volumes and flow rates, and get lighter throughout delivery without the need for expensive maintenance and/or service infrastructure. However, oftentimes drugs in these disposable systems need to stay within a specific flow rate window, but they cannot alert a patient if the device becomes blocked or otherwise occluded. Compared to reusable systems, disposable systems generally do not rely on large, bulky electronics for proper operation, rather, these devices typically use their inherent elasticity to create a drug delivery pressure that, combined with tubing resistance, results in a predetermined drug flow rate. Conversely, reusable systems oftentimes have large power supplies that enable continued use for multiple days, and typically include a user interface having multiple, complex menus. In some examples, flow rate monitors may be used to monitor and adjust fluid flow of the drug. However, these systems are typically power-hungry and can have undesirable fluid pressure accuracies during varying stages of the drug administration process.
As described in more detail below, the present disclosure sets forth systems and methods for dosing techniques embodying advantageous alternatives to existing systems and methods, and that may address one or more of the challenges or needs mentioned herein, as well as provide other benefits and advantages.
In accordance with a first aspect, a drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, and a flow rate monitor. The delivery container further includes inlet and outlet ports and is constructed from a resilient material that exerts an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user. The flow rate monitor is operably coupled to at least one of the delivery container or the supply line and includes a digital controller, a fluid valve operably coupled to the digital controller, and a diaphragm assembly in fluid communication with the fluid valve and operably coupled to the digital controller. The fluid valve, the diaphragm assembly, and the digital controller cooperate to regulate a flow rate of the drug.
In some examples, the digital controller causes the fluid flow control device to actuate the fluid valve or valves. The fluid valve may be in the form of a primary three-way valve and a secondary three-way valve. The primary three-way valve includes a primary valve inlet, a first primary valve outlet, and a second primary valve outlet. The secondary three-way valve includes a first secondary valve inlet, a second secondary valve inlet, and a secondary valve outlet. The primary and secondary three-way valves are ganged or otherwise coupled to each-other. In other examples, the fluid valve may be in the form of a four-way valve.
In some examples, the diaphragm assembly includes a reservoir that defines an internal volume, a first side port, and a second side port. The diaphragm assembly further includes a diaphragm disposed within the internal volume of the reservoir between the first and second side ports to define first and second cavities. The diaphragm may be constructed from a resilient material.
In some examples, at least one end of travel sensor is provided that senses at least one directional limit of the diaphragm. In some of these approaches, the end of travel sensor may be in the form of an optical sensor. In other approaches, the end of travel sensor may be in the form of at least one of an electrical contact sensor or a capacitive sensor. In other examples, the end of travel sensor may be in the form of a Hall Effect sensor or a pressure monitor. Other examples are possible.
In some approaches, the flow rate monitor may further include an interface coupled to the digital controller to receive at least one input and a display coupled to the digital controller. Further, the system may include an alarm operably coupled to the digital controller, an air trap, a filter, a flow restrictor, and/or a fluid path compliance member disposed downstream of the flow digital controller.
In accordance with a first aspect, a drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, and a flow rate monitor. The delivery container further includes inlet and outlet ports and receives a driving force that causes the container body to exert an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user. The flow rate monitor is operably coupled to at least one of the delivery container or the supply line and includes a digital controller, a fluid valve operably coupled to the digital controller, and a diaphragm assembly in fluid communication with the fluid valve and operably coupled to the digital controller. The fluid valve, the diaphragm assembly, and the digital controller cooperate to regulate a flow rate of the drug.
The above needs are at least partially met through provision of the continuous dosing system and approaches described in the following detailed description, particularly when studied in conjunction with the drawings, wherein:
Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions and/or relative positioning of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of various embodiments of the present invention. Also, common but well-understood elements that are useful or necessary in a commercially feasible embodiment are often not depicted in order to facilitate a less obstructed view of these various embodiments. It will further be appreciated that certain actions and/or steps may be described or depicted in a particular order of occurrence while those skilled in the art will understand that such specificity with respect to sequence is not actually required. It will also be understood that the terms and expressions used herein have the ordinary technical meaning as is accorded to such terms and expressions by persons skilled in the technical field as set forth above except where different specific meanings have otherwise been set forth herein.
Turning to the figures, pursuant to these various embodiments, a disposable, take-home drug delivery system 100 is provided. The drug delivery system varies from an electromechanical programmable IV pump in that the systems such as the drug delivery system 100 described herein relies primarily and/or partially on material characteristics of the pump (as opposed to an external power source) to administer a drug to a patient. These take-home systems described herein are typically smaller, lower cost, and easier to use compared to electromechanical programmable IV pumps, and as a result, can be used in settings outside of a healthcare facility (e.g., at a patient's home, office, and/or other location). By focusing on a single therapeutic or class of therapeutics, a simpler approach to a user interface and risk assessment may be afforded, thereby potentially reducing costs of goods sold (“COGS”), power requirements, and size, thus increasing value to patients. The system 100 includes a small, energy efficient “add-on” unit that may be incorporated into a take-home pump system with minimal complexity. The system 100 may be used in intravenous, subcutaneous, intra-arterial, intramuscular, and/or epidural delivery approaches having delivery times between approximately five minutes and upwards of approximately 72 hours. By using the drug delivery system 100 described herein, patient anxiety and confusion is reduced due to the use of a positive pressure flow that eliminates the need for regulatory guidance for air bubble detection as compared to peristaltic pump mechanisms. The systems described herein provide an optional, single use, pre-programmed add-on unit that provides limited functionality at the patient level. Accordingly, the add-on system is simplified.
The system 100 includes a drug delivery container 102 (e.g., an intravenous drug delivery container) which could also be considered a medication reservoir that includes a container body 103 having an inner volume 104 that accommodates a drug 101 therein. In the illustrated example, the system 100 further includes a container 105 that surrounds the drug delivery container 102 for safety and other purposes. In some examples, the container 105 may be rigid. The inner volume 104 may be sterile. This container 102 may be an off-the shelf disposable elastomeric pump of any desired size. In the illustrated example, the delivery container 102 also functions as the drive mechanism that causes the drug 101 to be administered to the patient.
Specifically, the container body 103 may be constructed from an elastic and/or resilient material. Generally speaking, the container body 103 is in a relaxed state prior to filling the drug 101 therein, and upon inserting the drug 101 into the container body 103, the container body 103 is expanded or stretched outwardly, and the inner volume 104 increases. The elasticity of the container body 103 generates a contraction force on the inner volume 104 that ultimately is exerted on the drug 101 for drug administration. In some examples, the container body 103 may be resilient or non-resilient, but may receive a driving force exerted thereon that in turn causes the container body 103 to exert an urging force on the drug 101 for drug administration. In these examples, the driving force may come from a spring member. In other examples, the driving force may be generated by a non-resilient surface that translates generally linearly in a cylinder under pressure from a spring or other resilient member.
The container 102 further includes an inlet fill port or mechanism 106 and an outlet port or mechanism 108. These ports 106, 108 may be of any type to allow for selective coupling of drug containers, vials, syringes, and the like. In some examples, the inlet fill port 106 and the outlet fill port 108 may include a valve or sealing mechanism to selectively permit fluid flow, and may be capped to prevent external contamination. Coupled to the outlet port 108 is an IV pump supply line or tubing 110 that is operably coupled to the outlet fill port 108 and dimensioned to accommodate flow of the drug 101 for patient administration (for example, via IV needle 118). This IV supply line 110 may be an off the shelf item and may have any number of desired characteristics such as length and/or flexibility. Any number of additional components may be coupled to the IV supply line 110 such as, for example, clamps 112, clips, filters (e.g., air elimination filters or traps 114), flow restrictors 116 and the like.
Typically, healthcare professionals (e.g., clinical pharmacies) stock a variety of delivery containers 102, thereby enabling ready access to the reservoir and drive (i.e., the motive force). One such example brand of delivery containers 102 is Easy Pump (e.g., Easy Pump LT 125-5-S, LT 279-27-S, etc.) which may include inner volumes 104 varying from approximately 15 mL to approximately 500 mL. These models may be in the form of high flow, medium flow, low flow, and/or ultra-low flow, and may result in a wide array of desired drug flow rates (e.g., between approximately 0.3 mL/day and approximately 500 mL/hour). As a result, a nominal infusion time may vary between approximately 5 minutes and upwards of approximately 72 hours depending on the desired usage.
The system 100 additionally includes a flow rate monitor 120 that may be operably coupled to the IV supply line 110 to monitor a flow rate of the system 100. In some examples, the flow rate monitor 120 may be directly coupled to the outlet port 108. In some examples, the flow rate monitor 120 may be configured as a flow rate controller, and thus may include a digital controller 122, a power source 124, a fluid valve 126 operably coupled to the digital controller 122, and a diaphragm assembly 128 operably coupled to the digital controller 122 and in fluid communication with the IV supply line 110. The flow rate monitor 120 may additionally include any number of optional components such as, for example, an interface 130, an alarm 132, and a filter 134 (e.g., a 35 micron filter positioned upstream of the valve 126).
The flow rate monitor 120 may be provided with the drug delivery system 100 packaging to encourage its use (though its use is not required in the event a healthcare professional has strong preferences opposing its use). In other words, the flow rate monitor 120 may be an optional component in the take-home drug delivery system 100 that the healthcare professional and/or the patient may use as they deem appropriate. The flow rate monitor 120 may be in the form of a housing that accommodates each of the components therein, and may include an inlet port 120a and an outlet port 120b, each of which may include any number and/or types of connecting ports, and may include internal tubing 121 (or, in some examples, an internal flow channel) extending between the inlet port 120a and the outlet port 120b through which the drug 101 may pass.
The flow rate monitor 120 differs from complex electromechanical infusion pumps by lacking user/patient programmability. Specifically, the flow rate monitor 120 is “programmed” at a location that is upstream from the user's at-home environment (e.g., at a pharmacy prior to providing the patient with their prescription). In this sense, the flow rate monitor 120 may be viewed as a single-use, fixed programmed, pre-grammed or pre-programmed device that only provides the patient with a limited feature set (e.g., initiate or pause dosages). Further, compared to complex electromechanical IV pumping systems, the flow rate monitor 120 described herein additionally lacks the typical programmable features afforded to healthcare professionals. In some examples, the “programmability” afforded to healthcare professionals may be limited to simply inputting the prescribed drug and/or dosage information. Accordingly, in some examples, the flow rate monitor 120 may not be reprogrammable after an initial programming.
The digital controller 122 includes software 122a adapted to control its operation, any number of hardware elements 122b (such as, for example, a non-transitory memory module and/or processors), any number of inputs, any number of outputs, and any number of connections. The software 122a may be loaded directly onto a non-transitory memory module of the digital controller 122 in the form of a non-transitory computer readable medium, or may alternatively be located remotely from the digital controller 122 and be in communication with the digital controller 122 via any number of controlling approaches. The software 122a includes logic, commands, and/or executable program instructions which may contain logic and/or commands for controlling the flow rate monitor 120. The software 122a may or may not include an operating system, an operating environment, an application environment, and/or the user interface 130. Generally, the digital controller is adapted to cause the flow rate monitor to actuate the fluid valve or valves. The valve or valves may be solenoid driven, shape memory wire (e.g., muscle wire) driven, and/or motor driven. Other examples are possible.
The power source 124 may be any type of power source capable of powering the components in the flow rate monitor 120. For example, the power source 124 may be in the form of a single or multi-cell battery commonly used in a wrist watch dimensioned to power the flow rate monitor 120 during a complete administration cycle. In one example, 250 ml of drug 101 may be delivered over a period of four days with a bolus interval of 45 minutes. Accordingly, in this example, 128 doses of bolus will be administered at a rate of 1.953 ml per bolus. The flow rate monitor 120 may require a sensor power of 23 mAh, and a valve power of 0.7 mAh. Accordingly, a power source 124 capable of providing 75 mWh may be used. Other examples are possible.
The fluid valve 126 may be in the form of any number of three-way valves. For example, the fluid valve 126 may be in the form of a primary three-way valve 136 that includes a primary valve inlet 136a, a first primary valve outlet 136b, and a second primary valve outlet 136c. The fluid valve 126 further includes a secondary three-way valve 138 that includes a first secondary valve inlet 138a, a second secondary valve inlet 138b, and a secondary valve outlet 138c. The primary three-way valve 136 is coupled or ganged to the secondary three-way valve 138 such that selective switching of the primary three-way valve 136 also causes selective switching of the secondary three-way valve 138.
The primary valve inlet 136a selectively couples (e.g., via the digital controller 122) to one of the first primary valve inlet 136b or the second primary valve outlet 136c during operation. Further, the secondary valve outlet 138c selectively couples (e.g., via the digital controller 122 or through the ganged connection to the primary three-way valve 136) to one of the first secondary valve inlet 138a or the second secondary valve inlet 138b during operation. Generally, such operation allows the diaphragm assembly 128 to fill with drug 101 via the delivery container 102, and expel the drug out the outlet port 120b of the flow rate monitor 120.
The diaphragm assembly 128 includes a reservoir 140 defining an internal volume 140a and includes a first side port 140b and a second side port 140c. The diaphragm assembly 128 further includes a diaphragm 142 which may be constructed of a resilient and/or flexible material that is disposed within the internal volume 140a between the first side port 140b and the second side port 140c. The diaphragm 142 is constrained within the internal volume 140a of the reservoir 140 so the reservoir 140, when full and empty, offer predictable delivery cycle volumes. Lower resistance is preferred to enable flat delivery rates across a wider portion of the pressure curve of the delivery container 102. As a result, the diaphragm 142, combined with the reservoir 140, defines a first cavity 144 and a second cavity 145 (see, e.g.,
More specifically, as illustrated in
As shown in
Accordingly, the combination of timing and the confirmation that the diaphragm 142 has travelled a controlled distance allows the flow rate monitor 120 to effectively act as a flow meter that uses positive displacement instead of complex fluid properties (e.g., localized micro-heating and measurement of heat change with many assumptions in an algorithm such as laminar flow, a lack of bubbles, and/or device orientation that may be incorrect). As a result, the volume per cycle may be controlled down to low pressure levels (e.g., approximately 2-3 psi). Such a system has no frictional interface, thus minimizing pressure losses in the diaphragm assembly 128.
The user interface 130 may include a number of inputs (e.g., buttons) and/or displays that allow a healthcare professional and/or a patient to initially configure the flow rate monitor 120. Generally, the interface 130 includes a limited number of patient-level settings and inputs to reduce user confusion. For example, a healthcare professional may use the interface 130 to input a desired flow rate, a duration of drug delivery, and/or a risk profile for the specific drug 101 being administered, and this input or inputs will be transmitted to the digital controller 122. Accordingly, the flow rate monitor 120 will function as a flow controller. In some examples, all or some of this information may be already stored on the digital controller 122, and thus the healthcare professional may only need to enter the drug name and/or dosage. As previously stated, the software 122a on the digital controller 122 may be capable of determining desired output values required to operate the flow rate monitor 120 based on the input or inputs received from the interface 130 and determine required tolerances (e.g., threshold and/or alarm values), in which case the flow rate monitor 120 is used to monitor flow rates. Put another way, the interface 130 may be configured to only generate an output and may not receive any inputs beyond a selection of a desired drug.
The interface 130 may additionally include buttons that begin and/or pause operation of the system 100 so that a user may begin drug administration at a desired time. The interface 130 may also include a display that can indicates desired and/or actual flow values, error messages, remaining dosage time, and the like. In some examples, the interface may be disposed on or within the flow rate monitor 120, or optionally may be implemented via external connectivity (e.g., via a portable electronic device such as a smart phone, computer, tablet, etc.).
The optional alarm 132 may function as a feedback device to alert the user of a potential problem (e.g., a full and/or partial occlusion) in the system 100. The alarm may be in the form of a speaker that produces an audible noise, a buzzer that vibrates, and/or a light that flashes. Other examples are possible. Upon the digital controller 122 receiving an input value from the user interface 130 that indicates a desired drug and/or dosage to be administered, the digital controller 122 may optionally initiate a risk profile corresponding to the selected drug. This risk profile may include an indication of an allowable flow rate range for the particular drug 101 being administered and/or any additional important operational values associated with the drug. In these examples, upon a user inputting settings (e.g., the particular drug, a desired flow rate, etc.) into the interface 130, the digital controller 122 may determine the appropriate risk profile, which can include an alarm value, via software 122a. In the event that the sensed flow value obtained from the end of travel sensors 144 exceeds this alarm value, the digital controller 122 may transmit a signal that causes the alarm 132 to be triggered and/or actuated. For example, the alarm value may be a range of approximately 10-15% from the desired flow rate. In other words, if the measured or sensed flow rate is higher or lower than 10%-15% of the desired flow rate, the alarm may be triggered, thus alerting the user to take appropriate action. Advantageously, by using the alarm 132, the patient will no long need to restart on a new delivery cycle upon occurrence of an occlusion.
In some examples, the system 100 may additionally include at least one compliance member in the form of a flexible tube, a diaphragm, and/or a bellows that predictably absorb high frequency fluid displacement operation. Some drug delivery systems operating at high frequencies (e.g., more than 50% duty cycle, or where chamber is filling for at least 50% of the time) may need a compliance member to ensure delivery accuracy. Lower frequency delivery allows sufficient time to ‘equalize’ and create predictable delivery, but for high frequencies (e.g., when using components such as a rigid flow digital controller system) there may be reduced accuracy after the system has completely primed and eliminated air bubbles (e.g., compliance). A compliance member positioned downstream of the flow digital controller may assist in ensuring delivery accuracy.
So configured, the flow rate monitor 120 may be implemented as an optional component in existing delivery systems 100 used in a variety of locations including a patient's home, office, or other non-medical facility environment. In some examples, the flow rate monitor 120 may be water resistant or waterproof to enable use while a user bathes. The flow rate monitor 120 may be provided with a coiled second supply line that automatically retracts, thus staying out of the way of the user.
Advantageously, the flow rate monitor 120 provides increased accuracy as compared to conventional reusable systems (e.g., conventional systems have an accuracy of approximately ±15%, while the system described herein may result in an accuracy of approximately ±6%) and may reduce and/or eliminate patient sensitivity to running out of drug 101. The flow rate monitor 120 may allow for a constant pressure to be delivered over longer periods of time. Further, the need to overfill the container 102 is eliminated due to less wasted medication and feedback in the case of blockage. Advantageously, alarms are minimized through the use of custom risk profile based on the specific drug 101.
The flow rate monitor 120 may be replaced at each refill interval, so battery 124 needn't occupy a large volume. Accordingly, the flow rate monitor 120 may have a small, discrete, patient-friendly size that is easy to transport and is suitable for pain management. In some examples, by pairing a relatively high flow displacement pump with the flow rate monitor 120, a low duty cycle may be provided that only allows flow for approximately 6% of the overall administration time, thereby reducing amount of time the valve 126 needs to be powered. Most drug delivery cycles may be averaged over time such that the flow rate monitor 120 delivers numerous high flow rates for short periods of time, which is the clinical equivalent to constant, low flow rates.

The end of travel sensor 146 may be used to determine if under delivery of the drug 101 may be sufficient. For example, a pressure differential may be present if the delivery cycle was successful, or equal input/output pressures may be expected if the cycle was unsuccessful. Accordingly, a differential pressure sensor may be positioned on the inlet/outlet lines that determine whether to reject an “increment” to the cycle count that updates the delivered volume.
