referring to fig1 a perspective view of the instructional card 10 , shows an envelope 12 that contains the functional components ( shown in fig5 ) of the card . the envelope 12 may be an envelope , box , laminate or other appropriate container of the components of the instructional card 10 . the instructional card 10 has a front 26 that indicates a button 14 to be depressed to activate the audio output and / or visual display features of the instructional card 10 . the front 26 of the instructional card 10 contains a window 28 through which the user may view the video display unit 18 . the front 26 of the instructional card 10 also has openings 16 to allow sound to be heard by the user when the audio components of the instructional card 10 are activated . the instructional card 10 may display an icon 20 that indicates the particular first aid situation that will be addressed by that particular instructional card 10 . a color - coded band 22 may also be placed on the instructional card 10 . the color - coded band 22 will correspond to a color - coded pack of supplies ( depicted in fig6 ) that contains the supplies the user would need to administer the particular first aid situation addressed by the instructional card 10 . written instructions 24 that correspond to the audio and / or video instructions may also appear on the instructional card 10 . the written instructions may also include instructions on the use of particular first aid supplies for treating the first aid situation , such supplies being contained in the packs of fig6 and may further include graphical depictions of the first aid instructions to guide the administering of first aid to an injured person . [ 0020 ] fig2 is a circuit diagram of the components of the instructional card with one switch to activate both the audio output and video components . a switch 30 , such as an interrupt switch for example , signals a processor 32 such as a microprocessor or a digital signal processor ( dsp ), that the button 14 ( shown in fig1 ) has been depressed . the microprocessor 32 is powered by a power source 34 that is typically a battery . other power supplies known in the art may also be used with embodiments of the present invention . the microprocessor 32 accesses a memory chip 36 for a digitally stored sound file . the memory chip 36 also stores at least one program . words of data from the digital sound file are fed through a register 38 to a digital - to - analog converter 40 , which produces an analog audio signal that drives the associated speaker 42 to output sound . to activate the video instructions , the microprocessor 32 sends message data to a video controller 44 and the video controller 44 renders the message data into a video random access memory 46 (“ ram ”) for output to the video display 18 . alternatively , the function of the video controller may be performed by the processor 32 . fig3 is the circuit diagram of fig2 with a second switch 31 to allow separate signals to the processor to active the audio and visual components of the instructional card 10 separately . the operational process of the instructional card 10 having an audio and , optionally , video instructions or output . the audio and video instructions are coordinated in time so that specific words are outputted to the speaker 42 at the same time that a particular video frame is outputted to the video display 18 . the operation diagramed in fig4 begins when the processor receives input from the user . input from the user is entered upon processor power up or upon interrupt caused by switch activation . the processor will retrieve from memory a message file corresponding to the user input . the processor will be directed , in the case of an instructional card having an audio output as in fig4 to get a first portion of an audio file . the audio file will be sent to the digital - to - audio converter and subsequently converted for output from a speaker . upon retrieving the portion of audio file , a first video frame or message will be rendered and sent to the video display . the retrieval and output of audio and , if available , video messages will continue until the files containing the audio and video messages no longer contains a next portion of audio or a next frame of video message . [ 0023 ] fig5 depicts the components of the instructional card 10 that are embedded in a substrate 48 . the substrate may be foam , such as styrofoam , or other foam or cushioning material of sufficient durability and flexibility to hold the components in place and prevent damage due to crushing or dropping of the instructional card 10 . the switch 30 is held within the substrate 18 and connected to the microprocessor 32 on a circuit board 50 by a wire connection 33 . the circuit board 50 supports the microprocessor 32 , power supply 34 , video controller 44 , video ram 46 , memory 36 , register 38 , and digital - to - analog converter 40 . the video controller 44 on the circuit board 50 is connected to the video display 18 by a video wire 45 . the speaker 42 is connected to the digital - to - analog converter 40 by a speaker wire 41 . the instructional card 10 may be assembled to include only the audio components , or only the video components . the instructional card 10 is included in a first aid kit 60 , for example as depicted in fig6 . the instructional card 10 may be contained within a pack 62 of first aid supplies required to treat the first aid situation described on the instructional card 10 as depicted in fig6 a . alternatively , as shown in fig6 b , the first aid supply pack 62 may display a color - coded band 64 and / or icon 66 corresponding to the color - coded band 22 and icon 20 on the instructional card 10 . the instructional card 10 and corresponding pack 62 may be numbered 23 , 63 as well . the pack 62 containing the instructional card 10 of fig6 a may be placed within the first aid kit 60 sequentially . alternatively , the pack 62 and separate corresponding instructional card 10 of fig6 b , may be arranged together in the first aid kit 10 . the first aid kit 60 contains a plurality of packs 62 as shown in fig6 . each pack 62 contains the first aid supplies required to treat a particular first aid situation and the corresponding instructional card 10 includes instructions on how to administer first aid for that particular situation . the first aid situations for which a pack 62 and instructional card 10 are prepared may include breathing , bleeding , shock , head and spine , bone , eye , burn and bite injuries . the color - coded bands 22 , 64 are unique and different for each pack 62 . in cases were first aid may be administered for a particular situation and no first aid supplies are required , an instructional card 10 may be included in the first aid kit 60 without a corresponding pack . for example , an instructional card 10 may contain audio , video and written instructions for cardiopulmonary resuscitation (“ cpr ”) without a corresponding pack , or an instructional card 10 describing treatment of a person who ingested a poison may not have a corresponding pack . the plurality of packs 62 may be arranged within a plurality of compartments 68 within the first aid kit 60 or otherwise sequentially arranged for a card catalogue / filing cabinet effect . it should be understood that various changes and modifications preferred in the embodiment described herein will be apparent to those skilled in the art . such changes and modifications can be made without departing from the spirit and scope of the present invention and without demising its attendant advantages . it is therefore intended that such changes and modifications be covered by the appended claims .
an instructional card for a first aid kit that gives instructions for administering first aid by audio means , visual means , written means , graphical means or a combination of means thereof . the instructional card may be identified as corresponding to a pack of first aid supplies to be used to administer the first aid treatment as instructed by the instructional card . alternatively , the instructional card may be included inside the pack of first aid supplies that are to be used to administer the first aid treatment described by the instructional card .
