There are a number of medicaments that require temperature regulation to maintain their efficacy. Some of these medicaments must be transported from one place to another for administration to a user at a certain time. During transportation of these medicaments the temperature of the medicament must remain at a certain level in order to preserve the efficacy of the medicament. If the medicament temperature falls below a certain low threshold level, or increases above a certain high threshold level, the medicament may no longer function as intended in the user. Consequently, it is of utmost importance to monitor the temperature of a medicament up until the time of administration thereof.
Portable insulated containers are known to maintain contents at a cold temperature for a period of time. Prior art containers typically include hard or soft body construction, and one or more cooling units, which may often include ice, disposed therein to cool the contents of the container for a limited amount of time by transferring heat energy between the ice and the product.
A more particular description briefly stated above will be rendered by reference to specific embodiments thereof that are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments and are not therefore to be considered to be limiting of its scope, the embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
For the purposes of promoting an understanding of the principles and operation of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated container and method, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to those skilled in the art to which the invention pertains.
It is to be noted that the terms “first,” “second,” and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, unless otherwise specifically stated herein. The terms “a” and “an” do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. The modifier “about” used in connection with a quantity is inclusive of the stated value and has the meaning dictated by the context. Furthermore, to the extent that the terms “including,” “includes,” “having,” “has,” “with,” or variants thereof are used in either the detailed description and/or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”
It is to be noted that all ranges disclosed within this specification are inclusive and are independently combinable. Notwithstanding that the numerical ranges and parameters setting forth the broad scope are approximations, the numerical values set forth in specific non-limiting examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. As a non-limiting example, a range of “less than 10” can include any and all sub-ranges between (and including) the minimum value of zero and the maximum value of 10, that is, any and all sub-ranges having a minimum value of equal to or greater than zero and a maximum value of equal to or less than 10, e.g., 1 to 7.
The term “freezing unit” as used herein may refer to a machine for maintaining a temperature at least below 40 degrees Fahrenheit, more particularly, for maintaining a temperature below zero degrees Fahrenheit, for example, a freezer.
The term “medicament” as used in describing the various embodiments of this invention includes an injectable liquid medicine, medication, drug, pharmaceutical, vaccine, prescriptive, agent, antidote, anti-venom, hormone, stimulant, vasodilator, anesthetic, nutritional supplement, vitamin and/or mineral compound, saline solution, biological, organic compound, genetically and/or chemically modified protein and/or nucleic acids, or other liquid that is adapted to be injected into the tissue of a subject.
The term associated or association, as used herein, includes but is not limited to direct and indirect attachment, adjacent to, in contact with, partially or fully attached to, and/or in close proximity therewith. The term “in conjunction with” as used herein includes but is not limited to synchronously or near synchronous timing, the phrase may also include the timing of outputs, where one output directly follows another output.
As used herein, the terms “subject”, “user” and “patient” are used interchangeably. As used herein, the term “subject” refers to an animal, preferably a mammal such as a non-primate (e.g., cows, pigs, horses, cats, dogs, rats etc.) and a primate (e.g., monkey and human), and most preferably a human.
As used herein, the term “efficacy” refers to the capacity for sufficient therapeutic effect or beneficial change in a patient in a clinical setting, for example, for a given intervention. Efficacy refers to the minimum threshold required to achieve a positive effect in a patient.
The inventors have discovered herein a new and useful portable insulated medicament container for maintaining a medicament at a predetermined temperature to comply with the medicament instructions for use (IFU) and/or to prevent medicament expiration, and provide for a means for traveling with a medicament without access to refrigeration. The efficacy of medicaments which are required to be kept at temperatures between 2-8 degrees Celsius, for example, depends on the medicament being maintained within the temperature range indicated for the particular medicament. Achieving this objective is often difficult when doses must be delivered to a user throughout the day, and accessibility to a refrigerator or freezer is not always possible. Furthermore, many cooling packs for holding medicament either: 1) do not maintain the medicament within the required predetermined range, and/or 2) require a warming or normalization period between removal of the cooling pack from a cooling environment such as a freezer, for example, and prior to placement of the medicament within the cooling pack, therefore increasing the wait time prior to departure in order to avoid over-cooling, or possibly freezing the medicament rendering it inactive or less effective. Further, overly cooled or frozen medicament is quite painful to administer by way of parenteral administration; and therefore, temperature regulation of medicament is not only crucial for maintaining the stability of the medicament, but also for patient comfort.
The described normalization period has been the standard in the industry, requiring users to specifically follow the instructions preventing the insertion of the medicament into the cooling pack immediately upon removal of the cooling pack and/or the cooling elements within the cooling pack from the cooling environment. Typically, the prescribed normalization period extends 20 minutes from removal of the cooling pack or container from the cooling environment, and prior to disposing the medicament device into the container. Problems which may be encountered with these prior art cooling packs or containers which require the warming, or normalization period before use include risk of cooling the medicament below recommended temperature risking destroying the efficacy of the medicament by inserting the medicament into the cooling pack prior to completion of the normalization (wait) time as aforementioned, or the inconvenience associated with waiting to place the medicament into the cooling pack until the typically-required 15-20 minutes following removal of the pack or the cooling units from the cooling environment.
Oftentimes, users are unaware of the required normalization period or wait time, or are in a hurry, and therefore place the medicament device into the container prior to completion of the normalization period/warming period. Therefore, in embodiments herein, the term “warming period or “normalization period” in reference to the container or cooling elements includes a time period defined as between removal of the container and/or the cooling elements from a cooling environment, and prior to placement of a medicament device into the container containing the cooling elements.
