TEMPERATURE INDICATOR FOR DRUG DELIVERY DEVICE

FIELD OF DISCLOSURE

The present disclosure generally relates to drug delivery devices and, more particularly, to drug delivery devices having temperature indicator assemblies to assist with drug administration.

BACKGROUND

Drug delivery devices, such as injectors, are used to deliver liquid drugs to a patient. Upon activation, a drug delivery device may expel a drug stored within an internal reservoir of a primary container through a needle, cannula, or other delivery member into the patient. Some drug delivery devices may be temporarily attached to a patient to deliver a drug via an injection needle or some other means over an extended period of time. The drug delivery device may be adhesively attached to the tissue of the patient's abdomen, thigh, arm, or some other portion of the patient's body.

Many medicaments require refrigeration to maintain stability and performance. Accordingly, it is common for these medicaments to be labeled for cold storage during manufacturing, transportation, and storage processes prior to patient and/or clinician use. These medicaments are often stored at temperatures ranging from approximately 2° C. and approximately 8° C. to support standard household refrigerators, and must be sufficiently warmed prior to administration in order to minimize pain and to ensure the delivery device functions properly and as intended. Patients may be hesitant to administer these drugs due to warming techniques which may result in risking administering a cold injection or require extended delivery times if the patient fails to wait an appropriate length of time after removing the device from refrigeration. These contributing factors which may extend the time of the perceived injection experience or add discomfort to the user may risk reducing adherence to therapy.

Patients desire both a comfortable and predictable injection experience. Administering injections using devices at substantially similar temperatures often yields substantially similar experiences. Differences of medicament temperatures at the time of administration of approximately 5° C. or more are likely to cause discernible differences to the patient, particularly in medicaments having highly temperature-dependent viscosities, which may lead to hesitation and uncertainty in administering subsequent doses. This in turn may lead to reduced adherence levels.

As described in more detail below, the present disclosure sets forth systems for delivery devices 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.

SUMMARY

In accordance with a first aspect, a drug delivery device includes a housing, a container disposed in the housing, an activation mechanism, a needle assembly, and a temperature indicator. The housing defines an inner volume and includes at least one opening. The container contains a medicament which is urged out of the container by the activation mechanism. The needle assembly has a needle and/or a cannula to deliver the medicament from the container. The temperature indicator is operably coupled with the outer surface of the container and is responsive to a change in temperature of the container. In some approaches, the temperature indicator is in the form of a reversible thermochromic sensor having a first operational temperature range.

In some examples, the drug delivery device may further include a window adapted to cover the at least one opening. The window may be a magnifier window. Further, in some examples, the window may be coupled with the temperature indicator.

In these and other examples, the drug delivery device may further include an insulating member disposed around an outer sidewall of the temperature indicator. The insulating member thermally insulates the temperature indicator from the housing.

DETAILED DESCRIPTION

The present disclosure generally relates to a temperature indicator for a drug delivery device that provides a visual indication to a user when the drug delivery device has reached a suitable temperature for drug administration. Injectable drugs are typically stored in cooling devices such as refrigerators at temperatures ranging between approximately 2° C. to approximately 8° C. Patients are recommended to wait until the drug has increased in temperature before administering the drug to aid in administration comfort. The drug delivery devices, and more specifically, the temperature indicators, described herein provide for an accurate visual indication for when the drug has reached a suitable temperature for injection.

Referring to the Figures, a general drug delivery device 100 is provided in the form of an autoinjector having a vertically oriented configuration with some or all drug delivery components disposed in stacked relation along a longitudinal axis L within a housing 102 thereof. As a more specific example, the device 100 can be configured to operate and inject a user with the device 100 oriented generally perpendicular to a skin surface of the user. The drug delivery device 100 can include the aforementioned housing 102 that defines an inner volume 102a and at least one opening 104, a container 110, an activation mechanism 120, a needle assembly 130, and a temperature indicator 150, each of which is at least partially disposed within the inner volume 102a of the housing 102.

In some embodiments, including the one illustrated in FIG. 1, the drug delivery device 100 may be configured as an autoinjector or a pen injector. In other embodiments, the drug delivery device 100 may be in the form of a hybrid handheld device, a wearable drug delivery device such as an on-body injector or an ambulatory infusion pump that may be releasably coupled with a patient, or any other type of handheld devices including hybrids thereof. The drug delivery device 100 may be operated to subcutaneously or transdermally deliver a drug to a patient. The drug delivery device 100 may be configured to automatically deliver a fixed or a patient/operator-settable dose of a drug over a fixed and/or a patient/operator-settable period of time. The drug delivery device 100 may be intended for self-administration by the patient, and in some examples, may be used by a caregiver or a formally trained healthcare provider to administer an injection.

The container 110 includes an outer surface 110a and an interior volume 112. The container 110 (which, in some examples, may be referred to as a primary container) further accommodates a piston 114 within the interior volume 112 thereof. The piston 114 is moveably disposed within the container 110 along the longitudinal axis “L” and has a first end 114a that includes an interior surface 115. The interior surface of the container 110 and the interior surface 115 of the piston 114 define a reservoir to contain a drug or medicament 101. Generally, the at least one opening 104 is aligned with the container 110 to allow a user to see at least a portion of the outer surface 110a of the container 110 for the purposes of completing a visual inspection and/or to determine a quantity of remaining drug and/or medicament 101 prior to, during, and after drug administration.

The volume of the drug 101 contained in the reservoir prior to delivery may be: any volume in a range between approximately (e.g., ±10%) 0.5-20 mL, or any volume in a range between approximately (e.g., ±10%) 0.5-10 mL, or any volume in a range between approximately (e.g., ±10%) 1-10 mL, or any volume in a range between approximately (e.g., ±10%) 1-8 mL, or any volume in a range between approximately (e.g., ±10%) 1-5 mL, or any volume in a range between approximately (e.g., ±10%) 1-3.5 mL, or any volume in a range between approximately (e.g., ±10%) 1-3 mL, or any volume in a range between approximately (e.g., ±10%) 1-2.5 mL, or any volume in a range between approximately (e.g., ±10%) 1-2 mL, or any volume equal to or less than approximately (e.g., ±10%) 4 mL, or any volume equal to or less than approximately (e.g., ±10%) 3.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 3 mL, or any volume equal to or less than approximately (e.g., ±10%) 2.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 2 mL, or any volume equal to or less than approximately (e.g., ±10%) 1.5 mL, or any volume equal to or less than approximately (e.g., ±10%) 1 mL, or any volume equal to or greater than approximately (e.g., ±10%) 2 mL, or any volume equal to or greater than approximately (e.g., ±10%) 2.5 mL, or any volume equal to or greater than approximately (e.g., ±10%) 3 mL. The reservoir may be completely or partially filled with the drug or medicament 101. The drug or medicament 101 may be one or more of the drugs listed below under the heading “Drug Information”, such as, for example, a granulocyte colony-stimulating factor (G-CSF), a PCSK9 (Proprotein Convertase Subtilisin/Kexin Type 9) specific antibody, a sclerostin antibody, or a calcitonin gene-related peptide (CGRP) antibody.

The activation mechanism 120 is coupled to a piston rod 122 to drive the piston 114 through the container 110. The activation mechanism 120 may be in the form of any number of suitable components capable of exerting a force to urge the drug or medicament 101 out of the container 110. In some examples, the activation mechanism 120 may include a user input device 124 such as, for example, a button, that may be engageable by a user to initiate drug delivery. In some examples, the drug delivery device 100 may include a controller 126 that is in electrical and/or mechanical communication with the user input device 124 to control operation of the activation mechanism 120.

The needle assembly 130 is operably coupled with the activation mechanism 120 to insert a needle and/or a cannula 132 to deliver the drug or medicament 101. More specifically, the needle assembly 130 includes the needle and/or cannula 132 oriented along the longitudinal axis L, a flow path 134 fluidly coupling the reservoir to the needle and/or cannula 132, and an actuation assembly 136 configured to insert the needle and/or cannula 132 to a desired subcutaneous depth within the user. By some approaches, the actuation assembly 136 can be a retractable needle guard to expose the needle and/or cannula 132 or a drive mechanism to longitudinally move the needle and/or cannula 132 a desired distance.

In some examples, the activation mechanism 120 may be configured to drive both movement of the piston 114 and the needle and/or cannula 132 by moving any combination of the container 110, the flow path 134, and/or the needle and/or cannula 132. As commonly configured, one or more of the components of the device 100, such as the drive mechanism 108 and needle insertion mechanism 116, can be operable in response to actuation of a user input device 124 which is accessible on an exterior of the housing 102. Suitable activation mechanisms 120 include, but are not limited to, springs, gas sources, phase changing materials, motors, or other electromechanical systems. As previously noted, the controller 126 may control operation of one or more of the drug delivery components.

It will be understood that although FIG. 1 shows the components centered along the longitudinal axis L, one or more of the components can be disposed off-center from the longitudinal axis L within the housing 102 and still be considered to be in a stacked relation. In one example, an autoinjector drug delivery device having drug delivery components in a stacked relation corresponds to the container 110 co-axially aligned with the needle and/or cannula 132. Examples of suitable autoinjector devices are described in U.S. Ser. No. 62/447,174, filed Jan. 17, 2017, which is hereby incorporated by reference herein.

The temperature indicator 150 may be in the form of a reversible thermochromic sensor that changes a visual property thereof in response to a change in temperature. More specifically, the temperature indicator 150 may be in the form of a liquid crystal and/or a leuco dye member that is thermally coupled with the outer surface 110a of the container 110. In some examples, the temperature indicator 150 may be in the form of a disc member that is affixed and/or adhered directly to the outer surface 110a of the container 110. In other examples, the temperature indicator 150 may be in the form of a label, strip, or painted component affixed to the container 110. The temperature indicator 150 or label may be constructed from polypropylene, polyester, LD polyethylene, polyolefin, paper, vinyl, and/or a combination thereof. The temperature responsive component may be water-based, a solvent-based ink, or any combination thereof. Other examples of suitable materials are possible. The temperature indicator 150 may be constructed from a material having high thermal conductivity and elastomeric properties so that close physical contact with the container 110 provides for high thermal responsiveness.

In some examples, the temperature indicator 150 may be responsive to a designated temperature range such as, for example, between an administration temperature of approximately 15° C. and approximately 35° C., and preferably between approximately 22° C. and approximately 28° C. Other examples of suitable temperature ranges are possible. In some examples, the temperature indicator 150 may be a first color and/or pattern (e.g., generally clear) when exposed to a low temperature, and may shift to a second color and/or pattern (e.g., green) when being exposed to a higher temperature suitable for drug administration. In some examples, the temperature indicator 150 may change colors in a reversed manner.

As illustrated in FIGS. 1 and 2, in the first embodiment of the drug delivery device 100, the temperature indicator 150 is coupled with and positioned on the outer surface 110a of the container. The temperature indicator 150 is positioned with the opening 104 so that a user may look through the opening 104 to discern the color of the temperature indicator 150 (as well as to observe whether the drug or medicament 101 includes any particulates, discoloration, and/or abnormalities), and thus whether the drug or medicament 101 is at a suitable administration temperature. Such a configuration advantageously provides close proximity with the drug or medicament 101. More specifically, because the temperature indicator 150 is thermally coupled with the container 110, when the container 110 increases in temperature due to being removed from the refrigeration unit, the temperature indicator 150 will reflect the increase in temperature by changing colors.

A second embodiment of a drug delivery device 200 including a temperature indicator 250 is illustrated in FIGS. 3-5. It will be appreciated that the drug delivery device 200 illustrated in FIGS. 3-5 may include similar features to the drug delivery device 100, and accordingly, elements illustrated in FIGS. 3-5 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1 and 2 increased by 100. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery device 100 may be incorporated into the drug delivery device 200.

In this embodiment, the housing 202 includes a separate opening 204 specifically for visualizing the temperature indicator 250. Put differently, the housing 202 includes the above mentioned opening(s) 204 which may be used to visually inspect the container 210, and the drug or medicament 201 contained therein, as well as an additional opening 204′ that is used to provide visual access to the temperature indicator 250. The opening 204′ may be positioned at approximately 90° from the opening or openings 204, though other examples of suitable placements are possible. Further, it is appreciated that the cross-sectional shape, size, and/or thickness of the temperature indicator 250 (and thus, the respective opening 204′, may be customized depending on the design of the drug delivery device 200 and the location of the container 210 within the housing 202.

During preparation of the drug delivery device 200, care must be taken to ensure the visual indicator 250 is properly aligned with the opening 204′. By using a separate opening 204′, the remaining opening or openings 204 may be visually unblocked and accessible for inspection.

A third embodiment of a drug delivery device 300 including a temperature indicator 350 is illustrated in FIGS. 6 and 7. It will be appreciated that the drug delivery device 300 illustrated in FIGS. 6 and 7 may include similar features to the drug delivery devices 100, 200, and accordingly, elements illustrated in FIGS. 6 and 7 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-5 increased by 100 or 200. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100 and/or 200 may be incorporated into the drug delivery device 300.

In this embodiment, the temperature indicator 350 additionally includes a thermally insulating layer 352 positioned along a sidewall 351 of the temperature indicator 350. The thermally insulating layer 352 provides thermal insulation from the housing 302 and assists in creating an isothermal pathway between the outer surface 310a of the container 310 and the visually exposed surface of the temperature indicator 350. The thermally insulating layer 352 may be constructed from a number of materials such as, for example, woven fabric, fiberglass, fluoropolymer, foam, polyethylene, polypropylene, polystyrene, polyester, polyimide, poly(ethylene terephthalate) or polyolefin, which may trap a single or multiple pockets of air. Other suitable materials may be used. As before, the temperature indicator 350 may be constructed from a material having a high thermal conductivity and elastomeric property.

A fourth embodiment of a drug delivery device 400 including a temperature indicator 450 is illustrated in FIG. 8. It will be appreciated that the drug delivery device 400 illustrated in FIG. 8 may include similar features to the drug delivery devices 100, 200, and 300, and accordingly, elements illustrated in FIG. 8 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-7 increased by 100, 200, or 300. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, and/or 300 may be incorporated into the drug delivery device 400.

In this embodiment, the temperature indicator 450 additionally includes a window member 456 constructed from a transparent and/or translucent material. In this example, the window member 456 is coupled with and abuts the temperature indicator 450. Any change in color and/or pattern of the temperature indicator 450 can be seen through the window member 456. As before, the material, shape, and/or configuration of the temperature indicator 450, as well as the window member 456, may be selected to ensure the temperature indicator 450 is in physical contact with the outer surface 410a of the container 410.

A fifth embodiment of a drug delivery device 500 including a temperature indicator 550 is illustrated in FIGS. 9-11. It will be appreciated that the drug delivery device 500 illustrated in FIGS. 9-11 may include similar features to the drug delivery devices 100, 200, 300, and 400, and accordingly, elements illustrated in FIGS. 9-11 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-8 increased by 100, 200, 300, or 400. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, 300, and/or 400 may be incorporated into the drug delivery device 500.

In this embodiment, the temperature indicator 550 also includes a window member 556 constructed from a transparent and/or translucent material. In this example, however, the window member 556 is positioned to be generally flush with the housing 502 so as to reduce and/or eliminate any recesses formed in the opening 504′. The window member 556 may be in the form of a magnifying window that may assist the user with viewing the temperature indicator 550 through the opening 504′. As before, the cross-sectional shape, size, and/or thickness of the temperature indicator 550, the window member 556, and the relative locations thereof may be adjusted depending on the design of the drug delivery device 500.

A sixth embodiment of a drug delivery device 600 including a temperature indicator 650 is illustrated in FIG. 12. It will be appreciated that the drug delivery device 600 illustrated in FIG. 12 may include similar features to the drug delivery devices 100, 200, 300, 400, and 500, and accordingly, elements illustrated in FIG. 12 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-11 increased by 100, 200, 300, 400, or 500. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, 300, 400, and/or 500 may be incorporated into the drug delivery device 600.

In this embodiment, the temperature indicator 650 is in the form of a strip that entirely surrounds a portion of the outer surface 610a of the container 610. Accordingly, the container 610, and thus the temperature indicator 650, needn't be aligned with a particular opening 604 to allow a user to view the temperature indicator 650. While not illustrated in FIG. 12, the housing 602 may include an additional opening specifically for viewing the temperature indicator 650.

A seventh embodiment of a drug delivery device 700 including a temperature indicator 750 is illustrated in FIG. 13. It will be appreciated that the drug delivery device 700 illustrated in FIG. 13 may include similar features to the drug delivery devices 100, 200, 300, 400, 500, and 600, and accordingly, elements illustrated in FIG. 13 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-12 increased by 100, 200, 300, 400, 500, or 600. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, 300, 400, 500, and/or 600 may be incorporated into the drug delivery device 700.

In this embodiment, the temperature indicator 750 is in the form of a label that is adhered to the outer surface 710a of the container 710. Such a label may be adhered to the container 710 during the manufacturing process.

An eighth embodiment of a drug delivery device 800 including a temperature indicator 850 is illustrated in FIGS. 14-16. It will be appreciated that the drug delivery device 800 illustrated in FIGS. 14-16 may include similar features to the drug delivery devices 100, 200, 300, 400, 500, 600, and 700, and accordingly, elements illustrated in FIGS. 14-16 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-13 increased by 100, 200, 300, 400, 500, 600, or 700. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, 300, 400, 500, 600, and/or 700 may be incorporated into the drug delivery device 800.

In this embodiment, the temperature indicator 850 is in the form of a progressive display. More specifically, in the illustrated example, the temperature indicator 850 includes a first temperature indicator 850a, a second temperature indicator 850b, and a third temperature indicator 850c. Each of the temperature indicators 850a, 850b, 850c has a different temperature response range. More specifically, the first temperature indicator 850a is configured to act as a “control” that provides a visual indication of what the temperature indicator 850 will look like upon changing to the second color or pattern. As such, the first temperature indicator 850a may be configured to be unresponsive to changes in temperature that occur during typical use of the device 800.

The second temperature indicator 850b may be responsive to a second temperature range. For example, the second temperature indicator 850b may change colors and/or patterns when the outer surface 810a of the container 810 (and thus the drug or medicament 801) is between approximately 10° C. and approximately 16° C. The third temperature indicator 850c may be responsive to a third temperature range. For example, the third temperature indicator 850c may change colors and/or patterns when the outer surface 810a of the container 810 (and thus the drug or medicament 801) is between approximately 18° C. and approximately 20° C.

Accordingly, as illustrated in FIG. 14, when the temperature of the drug delivery device 800 remains below approximately 9° C., only the first temperature indicator 850a exhibits the “changed” color and/or pattern. As illustrated in FIG. 15, when the drug delivery device 800 warms to a temperature between approximately 10° C. to approximately 16° C., the second temperature indicator 850b changes to the same color and/or pattern as the first temperature indicator 850a. As illustrated in FIG. 16, when the drug delivery device 800 warms to a temperature between approximately 18° C. and approximately 20° C., the third temperature indicator 850c changes to the same color and/or pattern as the first and second temperature indicators 850a, 850b. In some examples, the first temperature indicator 850a may not be used.

A ninth embodiment of a drug delivery device 900 including a temperature indicator 950 is illustrated in FIGS. 17-19. It will be appreciated that the drug delivery device 900 illustrated in FIGS. 17-19 may include similar features to the drug delivery devices 100, 200, 300, 400, 500, 600, 700, and 800, and accordingly, elements illustrated in FIGS. 17-19 are designated by similar reference numbers indicated in the embodiment illustrated in FIGS. 1-16 increased by 100, 200, 300, 400, 500, 600, 700, or 800. Accordingly, these features will not be described in substantial detail. Further, it is appreciated that any of the elements described with regards to the drug delivery devices 100, 200, 300, 400, 500, 600, 700, and/or 800 may be incorporated into the drug delivery device 900.

In this embodiment, the temperature indicator 950 is also in the form of a progressive display. In this example, the first, second, and third temperature indicators 950a, 950b, 950b are elongated strips and/or labels that wrap around the outer surface 910a of the container 910.

So configured, by thermally coupling the described temperature indicators with the container as compared to the housing, the temperature indicator may identify more accurate temperatures, because the temperature of the container may not always be equal to the temperature of the housing. Further, the present designs reduce and/or eliminate a likelihood of a user inadvertently touching the temperature indicator, which could provide a false temperature reading.

It is appreciated that the drug delivery devices and temperature indicators may include any number of suitable alternatives. For example, while not illustrated, an alternative drug delivery device may incorporate a temperature indicator that is coupled to a conductive material that itself contacts the container.
