Abstract
The application describes a protective case for an auto-injector. The medicament contained within these auto-injectors can be susceptible to degradation due to exposure to extreme temperatures and light. Thus, one embodiment of the protective case reduces the rate of heat transfer between the internal storage compartment of the case and the external atmosphere by including particularly configured vacuum chambers. Additionally, as auto-injectors become smaller, portability can be desirable. Thus, another embodiment of the protective case includes low-profile cases that allow the user to keep the auto-injector with them, e.g., by attaching the case to a common everyday item.
Core Innovation
The invention is directed to a protective case for an auto-injector that dampens external vibrations. The case includes a housing with an inner layer and an outer layer, where at least a portion of the inner layer extends outwardly to the outer layer, and the outer layer has an external surface comprising a coating. The housing is configured to dampen external vibrations while also providing structural protection for the auto-injector and medicament contained by the auto-injector.
The invention further includes a power source and connectivity to an external device through a connectivity module, with the case configured to provide power to the case. In the embodiments described, the connectivity module connects the case to an external device, including wireless connectivity, and an interface module is used to monitor internal and external conditions. The invention also describes support for internal environment feedback through a user interface module providing feedback indicative of an internal environment of the case.
In addition, the invention describes a vibration-damping and protective configuration that can accommodate low and high aspect ratio auto-injectors, using an aspect ratio definition of width divided by height. The case is configured to protect multiple devices in a low-profile configuration and includes ergonomic external coating and textured grip surface embodiments. The disclosed embodiments also include feedback mechanisms such as display, audible feedback, location-related feedback, and feedback indicative of a presence of another auto-injector, including emergency responder contact behavior triggered in certain configurations.
Claims Coverage
The provided independent claims are clm-00001 and clm-00013. Across these claims, four main inventive features are directed to a vibration-dampening protective housing with a power source and external-device connectivity, and a user interface module that provides feedback indicative of an internal environment of the case.
Vibration-dampening multi-layer protective housing with outward-extending inner layer and coated outer surface
A protective case for an auto-injector comprising a housing comprising an inner layer and an outer layer, where the housing is configured to dampen external vibrations and wherein at least a portion of the inner layer extends outwardly to the outer layer, and where an external surface of the outer layer comprises a coating.
Power source for the protective case
A protective case for an auto-injector comprising a power source configured to provide power to the case.
Connectivity module connecting the case to an external device
A protective case for an auto-injector comprising a connectivity module configured to connect the case to an external device.
User interface module providing feedback indicative of an internal environment
A protective case for an auto-injector comprising a user interface module connected to the power source, wherein the user interface module provides feedback indicative of an internal environment of the case.
The independent claims cover a protective auto-injector case with a vibration-dampening inner/outer layered housing (with outward-extending inner layer and a coated outer surface), a power source, and either external-device connectivity (clm-00001) or a user interface module providing feedback indicative of an internal environment (clm-00013).
Stated Advantages
Dampens external vibrations.
Provides feedback indicative of an internal environment of the case.
Connects the case to an external device.
Supports holding auto-injectors based on an aspect ratio (width to height) constraint.
Provides feedback mechanisms including display and audible feedback (as further specified in dependent claims).
Documented Applications
Protective case use for an auto-injector, including embodiments that provide connectivity and user-interface feedback related to internal and external conditions.
Configurations where removal of the auto-injector causes external device contact with an emergency responder.
Protecting multiple auto-injector devices in a low-profile configuration.
