Theisolation region 105 may be formed from an insulating material such as, without limitation, silica aerogel with reinforcing fibers, e.g., Spaceloft™ insulation manufactured by Aspen Aerogel of Northborough, Mass., USA. - In some embodiments, a phase change material is used in addition or alternatively to the insulation material to protect the battery from damaging heat. For example, and without limitation, the phase change material may include sodium sulfate decahydrate (e.g., Glauber's salt) or a similar material whose phase change temperature is below the damage threshold temperature of the
battery cell 101. - This
isolation region 105 is sized to maintain the temperature of the battery cell (or cells) below its temperature limit when the case is subjected to the known time and temperature profile of an autoclave sterilization cycle. - The
battery pack 100 may further include at least one temperature sensor configured to sense the temperature of at least one of thehousing 107, theisolation region 105, or thebattery cell 101. For example, there may be at least one isolationregion temperature sensor 113 and/or at least one batterycell temperature sensor 115. - Referring to
FIG. 2 , abattery pack 200 may include abattery cell 201, ahousing 207, a firstouter terminal 209 a and a secondouter terminal 209 b, a first terminal 203 a andsecond terminal 203 b, a firstelectrical connection 211 a and a secondelectrical connection 211 b, and anisolation region 205, all similar to the embodiments as described above with respect toFIG. 1 . - In some embodiments, and as shown in
FIG. 2 ,battery pack 200 may further include a sterileterminal cap 217 configured to selectively cover at least one of the firstouter terminal 209 b and secondouter terminal 209 a. The sterileterminal cap 217 may be puncturable such that access to at least one of the firstouter terminal 209 b and secondouter terminal 209 a may be gained by piercing or removing a portion of the sterileterminal cap 217. This allows sterility of the terminals to be maintained underneath the sterileterminal cap 217 after autoclaving and during storage/installation into a surgical device. - Referring to
FIG. 3 , abattery pack 300 may include abattery cell 301, ahousing 307, a firstouter terminal 309 a and a secondouter terminal 309 b, a first terminal 303 a andsecond terminal 303 b, a firstelectrical connection 311 a and a secondelectrical connection 311 b, and anisolation region 305, all similar to the embodiments as described above with respect toFIG. 1 . - In some embodiments, and as shown in
FIG. 3 , theisolation region 305 may further include at least two layers, each layer being formed from at least one of a phase change material as described above or an insulation material as described above. In some embodiments where multiple layers include at least one phase change material, the phase change materials of each layer may be selected to have different phase change temperatures. For example, anouter layer 306 a may have a lower phase change temperature such that it melts at a first temperature and absorbs heat before aninner layer 306 b melts. - The
battery pack 300 may further include at least one temperature sensor configured to sense the temperature of at least one of thehousing 307, theisolation region 305, or thebattery cell 301. For example, there may be at least one isolationregion temperature sensor 313 and/or at least one batterycell temperature sensor 315. In embodiments where there are multiple layers in theisolation region 305, there may beadditional temperature sensors 314 for any combination of layers as desired. - An embodiment of a battery pack as described herein may protect a battery cell during a heating procedure. For example, during autoclaving, the heat of fusion of the phase change material enables the material to absorb a great deal of thermal energy, thus keeping heat from accumulating in the battery cell and thereby maintaining the cell (or cells) at a safe temperature.
- Referring to
FIG. 4 , further disclosed is abattery autoclaving system 400 that may include abattery pack 500 as described herein, a temperature sensor as described above, and anautoclave 401 configured to receive a temperature indication from the temperature sensor and to inhibit autoclaving (e.g., sterilization) when the temperature indication exceeds a predetermined value. - The autoclave may have a controller module designed to periodically or constantly monitor temperature indications from one or more temperature sensors. The
controller module 705 may include a processor, memory, and/or interface elements configured to communicate with one or more temperature sensors, an autoclave, and the like. The controller module may further be configured to shut down autoclaving or modify the temperature of autoclaving to avoid battery cell failure. The autoclave may alternatively be manually controlled based on a temperature display wherein the temperature information may be displayed on atext display 407 located on theautoclave 401, the housing, or through any other manner of indication such as audible means or visual display. - In some embodiments, a
temperature sensor 513 is operatively associated with thebattery pack 500 to enable a user to determine whether it is safe to autoclave thebattery pack 500. This may be beneficial in situations such as where heat from a prior, recent autoclaving procedure remains in the phase change material or the battery cell. In one scenario, the phase change material may be fully or partially liquefied (having already undergone a phase change during the previous autoclaving session) and thus not be able to fully absorb the necessary heat from another autoclaving session until it necessarily cools. The temperature information may be displayed on a text display located on the housing or through any other means such as audible means or visual display. - In some embodiments, the
temperature sensor 513 may be in operative communication with anautoclave 401 that is configured to receive a temperature signal from thetemperature sensor 513 indicative of an internal temperature of the battery pack, e.g., the temperature of the battery cell and/or the phase change material. The autoclave may be further configured to inhibit the autoclaving process in the case that one or more battery cells indicate that an internal temperature thereof exceeds a safe threshold for autoclaving. In an embodiment, theautoclave 401 may automatically determine the condition of any battery placed therein prior to initiating an autoclaving cycle. Theautoclave 401 may communicate with the battery by any suitable manner of communication, e.g., by electrical connection (e.g., via mating terminals on the battery and autoclave), by wireless connection (e.g., active or passive RFID tags), and/or or any other suitable communication link between the battery and the autoclave. Theautoclave 401 may even have an emergency door release feature to opendoor 403 and release heat quickly in the event of a near critical temperature reading inside the battery. Theautoclave 401 may even have an emergency vent feature to open one or more vents and release heat quickly in the event of a near critical temperature reading inside the battery. - Further disclosed is a method for autoclaving a battery pack. The method may include providing the battery pack as described above.
- The method may further include inserting the battery pack into an autoclave, sterilizing the battery pack in the autoclave, and removing the battery pack from the autoclave after sterilizing. The battery pack may be moved from the autoclave to a sterile storage area or into a sterile surgical device to maintain sterility.
- The method may further include providing an autoclave configured to accept the battery pack and to sterilize the battery pack.
- The method may further include monitoring the temperature of at least one of the housing, the battery cell, and the isolation region. The method may further include modifying the temperature of the autoclave or shutting down the autoclave in response to the monitored temperature.
- The method may further include providing a sterile terminal cap and placing the sterile terminal cap over at least one of the first or second outer terminals.
- The method may further include providing an autoclave configured to accept the battery pack and to sterilize the battery pack, wherein the autoclave is configure to read the at least one temperature sensor and provide an indication of temperature.
