For example, when the description states that a subject matter A may be or is adjacent to a subject matter B, this can be one of many possibilities including the possibility that the subject matter A is not adjacent to the subject matter B as it would be understood by a person of ordinarily skilled in the art.
[0031] Moreover, it is within the scope of the invention to combine the various embodiments disclosed relating to one or more particular drawing and their corresponding descriptions with one or more of other drawings and their corresponding descriptions when such combination is achievable by one of ordinary skilled in the art. The same referenced numerals referred to in the drawings and description generally correspond to same or similar parts throughout the disclosure.
[0032]
[0033]
[0034] The pocket 40 may be configured to hold one or more medical devices such as injector devices 50A and 50B and medicine 52. In particular, the medical devices 50A may general represent the outer shape and size of EPIPEN, the medical devices 50B may general represent the outer shape and size of AUVI-Q, and the medicines 52 may general represent the tablet form of BENADRYL. Note that the medical device and/or medicine which may be stored in the pocket 40 may be any device and/or medicine that may be sensitive to temperature fluctuation such as insulin for diabetes and nitroglycerin for heart disease. Moreover, the pocket 40 may be sized to have enough room to hold one or more medical devices 50A side by side and medicine 52 or the medical devices 50B arranged one on top of the other and medicine 52. Alternatively, the door 18 may slide open to expose the pocket 16 which is adapted to receive one or more medicines 52 for easy access by the user in case of an allergic reaction. Accordingly, the pocket 40 may be sized to hold more than one type of medical devices and medicine. In addition, some medical devices 50A may have a window 54 to allow the user to inspect the drug epinephrine contain therein to ensure that the epinephrine is still clear which may be indicative that the drug is still potent and effective. The pocket 40 may be configured so that the medical devices 50A may be held within the pocket 40 so that the window 54 may be aligned with the window 38 of the housing 12 to allow the user to inspect the drug in the medical devices 50A held within the pocket 40 without having to open the cover 14 and remove the medical device 50A to inspect the medical device.
[0035]
[0036] The housing 12 may have a first one-way valve 82 coupled to the first inner wall 64 to draw air out of the pocket 40 as indicated by the direction arrow 84 but not in the opposite direction or into the pocket 40. The sidewall 80 may have a second one-way valve 86 to draw air out of the first chamber 60 as indicated by the direction arrow 88 but not in the opposite direction or into the first chamber 60. Accordingly, once the cap 44 substantially seals the pocket 40, the air inside the pocket 40 may in effect only be removed via the first one-way valve 82 and no other means. As such, as the plunger 68 is withdrawn from the first chamber 60, the vacuum pressure is created therein since the atmospheric air cannot enter the first chamber 60 due to the second one-way valve 86 that prevents atmospheric air from entering the first chamber 60. The greater vacuum pressure (lower pressure) within the first chamber 60 relative the pressure within the pocket 40 causes the air within the pocket 40 to flow from the pocket 40 through the first one-way valve 82 and into the first chamber 60, thereby creating a vacuum pressure within the pocket 40. The housing 12 may have a block 90 near the opening of the first chamber 60 to engage with the seals 74 to stop the plunger 68 from fully withdrawing from the housing 12 once the plunger 68 has reached its extended position. To generate additional vacuum pressure within the pocket 40, the plunger 68 may be reinserted into the first chamber 60, which causes the air within the first chamber 60 to exit via the second one-way valve 86 but not via the first one-way valve 82 to maintain the vacuum pressure generated within the pocket 40 due to the first cycle of withdrawing the plunger 68 from the first chamber 60. As such, as the plunger 60 is cycled in and out of the first chamber 60, in the manner discussed above, the vacuum pressure within the pocket 40 may be increased to hermitically seal the medical devices and medicine stored within the pocket 40 to substantially isolate the items from the atmosphere. In addition, with the vacuum pressure generated, i.e.less atoms, within the pocket 40, the temperature fluctuations within the pocket 40 may be minimized to keep the drug potent and effective for a longer period of time compared to the drug exposed to the atmosphere such as oxygen and extreme temperature fluctuations. Note that it is within the scope of the invention to utilize a variety of mechanisms and method for generating vacuum pressure within the pocket 40 such as through a motorized pump that may not require the one-way valve or valves.
[0037] The housing 12 may also have a door coupled to the housing 12 via a hinge 94 to allow the door 92 to open and close as indicated by the direction arrow 96. The door 92 allows access to the second chamber 62 to hold other items such as tablet medicines and other medical devices which may not be sensitive to atmosphere or temperature fluctuations.
[0038]
[0039]
[0040] In reference to
[0041] In order to hermitically seal another set of medical devices, the medical devices may be placed inside the pocket 40 and cover 14 may be closed. The handle 20 may be moved to the retracted position to seal the tube 104. Thereafter, vacuum pressure may be generated within the pocket 40 in a manner described above in reference to
[0042]
[0043] The pump 122 may include a barrel 124 with a protruding tubular member 126 adapted to releasably couple to the first one-way valve 82. The barrel 124 may have a chamber 60 adapted to receive the plunger 68 having a first end 70 and a second end 72. The first end 70 of the plunger 68 may have one or more seals 74 to provide substantial air tightness between the plunger 68 and the chamber 60 as the plunger 68 moves in and out of the chamber 60 as indicated by the double ended direction arrows 76. The second end 72 of the plunger 68 may have an opening 78 to allow a user to grab onto the plunger 68 to move the plunger 68 in and out of the chamber 60. The tubular member 126 may have the second one-way valve 86 to draw air out of the chamber 60 as indicated by the direction arrow 88. Accordingly, once the cap 44 substantially seals the pocket 40 and the protruding tube element 126 is coupled to the first one-way valve 82, the air inside the pocket 40 may be removed via the first one-way valve 82. That is, as the plunger 68 moves from the retracted position, as shown in
[0044] To generate additional vacuum pressure within the pocket 40, the plunger 68 may be reinserted into the chamber 60, which causes the air within the chamber 60 to exit via the second one-way valve 86 but not via the first one-way valve 82 to maintain the vacuum pressure generated within the pocket 40 due to the first cycle of withdrawing of the plunger 68. As the plunger 60 is cycled in and out of the chamber 60, in the manner discussed above, the vacuum pressure within the pocket 40 may be increased to hermitically seal the medical device and medicine stored within the pocket 40 to substantially isolate the items from the atmosphere. To open the cover 14 relative to the housing 12, the case 10B may include the handle and actuator system disclosed above in reference to
[0045]
[0046]
[0047] The processor 202 may control the battery 204 to provide power to the TEC 208 to control the temperature within the pocket 40. By way of background, the TEC 208 may utilize the Peltier effect where whenever direct current passes through the circuit of heterogeneous conductors, heat is either released or absorbed at the conductors' junctions, which depends on the polarity of direct current provided to the TEC. The amount of heat may be proportional to the current that passes through conductors. When direct current moves across a Peltier device, it causes temperature differential between the opposing sides. As a result, one side may be hotter compared to its opposite side or cooler than its opposite side, and vice versa, if the polarity of direct current is reversed. In general, if the heat generated on the hot side is effectively dissipated into heat sinks, such as a radiator, into the surrounding environment, then the temperature on the cold side may be much lower than that of the ambient by dozens of degrees. The TEC's cooling capacity may be proportional to the current passing through the interconnected conductors' junction layer.
[0048]
[0049]
[0050] A number of factors may impact the insulation of the medical device within the pocket 40 such as the amount of vacuum pressure generated by the user from cycling the plunger 68, time the case is exposed to the outer atmosphere, effectiveness of the seal around the cap 44, moisture in the air, the elevation or the altitude where the case is used, atmospheric temperature, and etc. In general, the vacuum pressure generated by manually cycling the plunger 68 within the chamber 60 may insulate the medical device from about 10 to about 30 F. for an average of about 20 F. below relative to the outside temperature for about 2 to 3 hours. For example, if a single insulated case such as the cases 10A and 10B, as described above, is carried outside with the initial temperature inside the pocket of about 80 F. (26.7 C.), and the outside the temperature is about 110 F. (43.3 C.), then the temperature inside the pocket 40 may rise to about 90 F. (32.2 C.) after about 2 to 3 hours of being exposed to the outside atmosphere. The performance of the double insulated case such as the case 10C described above may improve the insulation of the pocket 40 such that the temperature inside the pocket 40 may rise to about 90 F. (32.2 C.) after about 4 to 6 hours, for example, thus extending the period of insulating the pocket 40 compared to the single insulated case under similar atmospheric conditions. For many parts of the United States, and around the world, outside temperatures reaching above 110 F. (43.3 C.) is not uncommon during summer, such as in Phoenix, Ariz., and especially inside automobiles where the temperature can reach well over 140 F. (60.0 C.).
[0051] As with insulating the pocket 40, a number of factors may impact the performance of the TEC to cool or heat the pocket 40 such as the quality of the TEC, outside temperature, conductive material used for the radiator and thermal plate, thermal paste used to thermally couple the TEC to the radiator and the thermal plate, power of the fan, and etc. In general, the TEC may cool the pocket 40 from about 10 to about 30 F. for an average of about 20 F. below relative to the outside temperature. On the other hand, the TEC may heat the pocket 40 from about 30 to about 50 F. for an average of about 40 F. above relative to the outside temperature. For example, if the temperature inside the pocket reaches about 90 F. (32.2 C.), then the temperature adjustment system 200 may cool the pocket to about 70 F. (21.1 C.). As another example, if the pocket temperature reaches about 40 F. (4.4 C.), then the temperature adjustment system 200 may heat the pocket to about 70 to about 90 F. (21.1 C.-32.2 C.). Accordingly, the case may utilize single or double insulations, as discussed above, along with the temperature adjustment system 200 to substantially insulate the medical device stored in the pocket within a desired temperature rang such as from 59 to 86 F. (15 -30 C.), and a narrower preferred temperature range from 68 to 77 F. (20 -25 C.) to prolong the life expectancy of the medicine and its effectiveness such as epinephrine.

[0053]
[0054]
[0055] In reference to
[0056] The application software 404 may also be preprogrammed to automatically contact a mobile transportation or ride-sharing service 418 such as UBER, LYFT and/or ambulance with a priority service with the pickup location based on the location of the phone 402 and the address of the hospital 410 based on the information stored in the phone 402 to transport the user to an emergency treatment center 410 without having the user drive his or her own vehicle when the user may not be in a proper physical condition to drive the vehicle or for minors who cannot drive. The phone 402 may contact the mobile transportation service 418 via a direct communication line 414 and/or indirect communication line 416.
[0057] The system 400 may also connect other users of the case 10D to the user 402 via the network 406 for assistance. For instance, if the user 402 is without the case 10D or the medical device during an allergic reaction, the application software 404 may have a backup notification which the user can activate to seek assistance from other users nearby who has a medical device. That is, the system 400 may include a second type of users 420 and a third type of users 422. The second type of users may be people who carry a medical device with them, and the third type of users 422 may be mobile transportation drivers such as drivers for UBER and LYFT. For example, in situations where the user 402 is without the case 10D or if the medical device has expired or if the user needs another shot of the drug from the medical device, the user 402 may activate the backup notification such that the phone 402 sends the notification to the network 406 via the communication line 416. The network 406 may then search the data base for other users nearby the user 402 based on the locations of the other users' phones 420 and 422, and request for assistance. For instance, mobile transportation drivers 422 may carry a case 10D or medical devices 50 with them in their vehicles 424, and when driver receives a notification for an emergency assistance, the driver nearby or nearest the user 402 may accept the notification and drive to the user 402 and deliver the case 10D and/or the medial device to be administered and drive the user to an emergency facility 410 for further treatment. Alternatively, the user 402 may receive a request for assistance from the other users such as the user 420, and if the user 402 is in a position to assist the user 420, the user 402 may accept the request and allow the other user 420 to use the user's 402 medical device 10.
[0058] The network 406 may also collect information from all the cases 10D utilized within the system 400 and provide helpful analytics information to the users. For instance, the case 10D may communicate the temperature within the pocket 40 to the phone 402 via the communication device 212 and the application software 404 may forward the temperature information to the network 406 to keep a record the temperature fluctuations within the pocket 40. The network 406 may periodically request the user to check the medical device 50 to determine if the drug is still potent such as by inspecting if the epinephrine is still clearwhich may be an indication that the drug is still potent and effective. If the epinephrine is not clear, this may be an indication that the drug is no longer potent. Such information about the temperature exposure history of the medical devices, the period of time it took for the drug to lose its potency, the geographic location of the drug, climate, and the like may be gather from the users within the system 400 and analyzed to predict a more accurate lifespan and effectiveness of the drug. Based on such analytics, the network 406 may send a notification to the application software 404 with its best predictions on the effectiveness of the drug along with recommendation on how to store the drug and when to replace the drug or medical device.
