turning now descriptively to the drawings , in which similar reference characters denote similar elements throughout the several views , fig1 through 8 illustrate a female security and rape prevention device indicated generally by the numeral 10 and shown in dashed lines in fig1 . the female security and rape prevention device 10 is positioned within a vaginal cavity 12 of a woman 14 . a midsection 16 of a woman 14 is illustrated in fig1 . the woman 14 is wearing an undergarment 18 and the female security and rape prevention device 10 is illustrated in dashed lines in position within the vaginal cavity 12 . the female security and rape prevention device 10 is positioned within the vaginal cavity 12 so as to be unobtrusive and not noticeable to persons other than the user . the female security and rape prevention device 10 is sized to fit within the vaginal cavity 12 as illustrated in fig2 and includes a cylindrical housing 20 having a first open end 22 and a second closed end 24 . the cylindrical housing 20 is made of an absorptive flexible material able to expand and contract with the walls of the vaginal cavity 12 . the first open end 22 includes a frontal pressure sensor 26 for sensing pressure caused by penile insertion and contracting upon sensing of pressure around the inserted penis . the second closed end 24 is preferably made of a flexible material and acts as a buffer to prevent trauma to the vaginal cavity 12 . the preferred material for the second closed end 24 is a flexible bladder made of latex and filled with a jell like substance . however , any material which is able to close the second end of the cylindrical housing 20 while maintaining a soft flexible texture able to prevent any trauma or damage to the vaginal cavity 12 when inserted therein may be used . a plurality of surface sensors 28 extend partially around an outer side 30 of the cylindrical housing 20 for sensing increased pressure exerted on and by the walls of the vaginal cavity 12 . a plurality of ribs 32 extend along an inner side 34 of the cylindrical housing 20 for expanding and contracting the cylindrical housing 20 along with the contractions of the walls of the vaginal cavity 12 and the insertion and pullback of a penis inserted therein . extending from the inner side 34 of the cylindrical housing 20 and into the cavity formed therein are first and second dual headed needles 36 and 38 for engaging a penis as it extends into the cylindrical housing 20 and injecting the penis with a tissue irritant . the first and second needles 36 and 38 are also able to take a tissue sample of the penis as it contacts the surface of the needles 36 and 38 . positioned at the second end 24 on the internal side of the cylindrical housing 20 is a connection device 40 for aiding in removal of the female security and rape prevention device 10 as will be discussed in more detail hereinafter with specific reference to fig6 . positioned within the connection device 40 is a microcomputer and auditory recording processor as will be discussed hereinafter with specific reference to fig4 and 5b . extending from the first end 22 of the cylindrical housing 20 are a pair of tabs 42 for use in removal of the female security and rape prevention device 10 from the vaginal cavity 12 . as is clearly illustrated in fig3 a plurality of internal surface pressure sensors 44 are also positioned on the inner side 34 of the cylindrical housing 20 . the internal surface pressure sensors 44 act to monitor penile advance within the female security and rape prevention device 10 and are connected to a reservoir 50 as shown in fig4 containing an identification dye therein for releasing the identification dye on the penis when it is sensed by the internal surface pressure sensors 44 that the penis has advanced a certain distance into the cylindrical housing 20 . the first and second needles 36 and 38 extend from the internal surface pressure sensors 44 and help monitor penile advancement into the cylindrical housing 20 . the first and second needles 36 and 38 trigger the internal surface pressure sensors 44 to release the identification dye from the reservoir 50 when they are contacted by a penis . a cut away portion of this figure also shows the jell substance 46 within the bladder 48 of the second closed end 24 . the positioning of the internal surface pressure sensors 44 , the reservoir 50 for retaining the identification dye and the first and second needles 36 and 38 within the cylindrical housing 20 is clearly illustrated in fig4 . a schematic diagram illustrating electrical components contained within the cylindrical housing 20 of the present invention and their interconnection is shown in fig5 . as can be seen in this figure the connection device 40 houses a microcomputer 52 and a power source 54 . the plurality of external surface sensors 28 are divided into first and second groups of sensors 56 and 58 , the first group 56 partially extending around a first half of the outer side 30 of the cylindrical housing 20 and the second group 58 partially extending around a second half of the outer side 30 of the cylindrical housing 20 . the microcomputer 52 is connected to the first group of external surface sensors 56 through a first connection wire 60 and to the second group of external surface sensors 56 through a second connection wire 62 . the microcomputer 52 is also connected to the internal surface pressure sensors 44 by third and fourth connection wires 64 and 66 . a switch 68 is also connected to the microcomputer 52 for manually activating the female security and rape prevention device 10 when it is determined by the user that a rape or unwanted sexual contact is eminent . the manual switch 68 allows for selective activation of the female security and rape prevention device 10 and thus will prolong the life of the power source 54 as it will not be drained constantly but only during times of need . fig5 a illustrates an optional form for the external pressure sensors 28 . instead of having first and second groups 56 and 58 of external pressure sensors 28 , a plurality of circular external pressure sensors 70 may be spacedly positioned along the length of the outer side 30 of the cylindrical housing 20 , each extending around the entire circumference of the cylindrical housing 20 . an additional auditory recording device 72 and a vibrator ring 74 are shown in fig5 b connected to the microcomputer 52 . the auditory recording device 72 is activated by the microcomputer 52 upon a determination that a rape is occurring and produces an auditory recording of the incident to provide further proof of the occurrence of a rape . the vibrator ring 74 is also activated by the microcomputer 52 upon a determination that a rape is occurring and causes the female security and rape prevention device 10 to vibrate thus alerting the user that it is activated . the determination by the microcomputer 52 that a rape is occurring is based upon an analysis of the signals received from both the external pressure sensors 28 and internal sensors 44 via the respective connection wires . fig5 c illustrates the use of a foam coating 76 for the external surface 30 of the cylindrical housing 20 . alternatively , the material coating the outer side 30 of the cylindrical housing 20 may be a jell , soft plastic or any other soft , pliable , conductive material which will not cause discomfort when inserted into the vaginal cavity 12 . furthermore , this material could be warmed by the body temperature of the user and thus be further concealed from a would - be attacker . an alternate way of connecting the external surface pressure sensors 78 is to embed or mold them in the foam cover layer 76 as depicted in fig5 d . this provides the female security and rape prevention device 10 with a smoother outer surface and thus is more comfortable for the user . the connection device 40 is illustrated in fig6 and includes a central portion 80 housing the microcomputer 52 along with the power supply and auditory recording device 72 as shown in fig5 b . depending from the central portion 80 is a skirt 82 including a lip 84 extending therearound . the combination of the skirt 82 and lip 84 create a recess above the central portion 80 . in order to remove the female security and rape prevention device 10 from its implanted position in the vaginal cavity 12 , a tong 86 including a pair of pivotal outwardly curling clips 88 extending therefrom is inserted into and through the cylindrical housing 20 to engage an underside of the lip 84 . once the pair of pivotal outwardly curling clips 88 engage the lip 84 the female security and rape prevention device 10 may be easily removed from within the vaginal cavity by pulling a handle 90 of the tong 86 in a direction away from the vaginal cavity 12 as is indicated by the arrow labeled 92 . an alternative device for removing the female security and rape prevention device 10 is illustrated in fig6 a and 6b . in this embodiment a lip 94 extends around the first open end 22 of the cylindrical housing 20 . this lip 94 may be used instead of the pair of tabs 42 described above with reference to fig2 and 3 . however , the removal of the female security and rape prevention device 10 is performed in the same manner when either is used . the use of the lip 94 or the pair of protrusions 42 is simply a design choice . in order to remove the device a pair of tongs 96 including a pair of pivotal inwardly curling clamps 98 connected to a handle portion 100 are inserted into the vaginal cavity 12 . the pair of pivotal inwardly curling clamps 98 are caused to engage the lip 94 and then a force is exerted on the handle portion 100 in the direction of the arrow labeled 102 out of the vaginal cavity 12 until the female security and rape prevention device 10 is removed therefrom . alternatively , the user may remove the female security and rape prevention device 10 without the pair of tongs 96 by grasping the pair of tabs 42 or lip 94 and exerting a force in the direction of the arrow 102 out of the vaginal cavity 12 . also contained within the inner side 34 of the cylindrical housing 20 is a surgical glue 104 as illustrated in fig7 . this surgical glue 104 is released upon pull back of the penis by the rapist and acts to form a seal 106 and close the front open end 22 of the cylindrical housing 20 preventing any further penile penetration . alternatively , a small air bag 108 as illustrated in fig8 may be retained within the cylindrical housing 20 and deployed to prevent further penile penetration . the air bag 108 is deployed to seal the first open end 22 of the cylindrical housing 20 upon a determination by the microcomputer 52 that a rape or some object has been inserted into the cylindrical housing 20 is occurring . the operation of the device will now be described with reference to the figures . in operation , the female security and rape prevention device 10 is inserted within the vaginal cavity 12 of a user by placing the female security and rape prevention device 10 at the entrance to the vaginal cavity 12 . a force is then exerted on either the pair of tabs 42 or the lips 94 towards the vaginal cavity 12 until the female security and rape prevention device 10 is fully inserted therein . due to the soft pliable nature of the material of which the female security and rape prevention device 10 is composed the user should feet a minimal amount of discomfort once the device is inserted . if the user feels a large amount of discomfort the device should either be adjusted within the vaginal cavity 12 until the discomfort is gone or removed , checked to make sure it is working properly , e . g . that the tissue irritant is not leaking , there are no sharp ends sticking through the outer surface or any other items which might be the cause of discomfort , and reinserted into the vaginal cavity 12 . while in the vaginal cavity 12 the female security and rape prevention device 10 should not prevent the user from performing any of her normal daily activities and thus the user can go on and perform all normal activities she would otherwise perform . if the user is presented with a rape situation , she may then activate the device using the switch 68 and thus the device should now be functional . upon activation of the switch 68 the vibrator ring 74 should vibrate to alert the user that the device is operational . if there is no switch to activate , the device will automatically activate when penile penetration into the cylindrical housing is sensed by the internal sensors 44 and contractions of the vaginal wall are sensed by the external surface pressure sensors 28 or 70 . these sensors send signals to the microcomputer 52 which analyze the signals to determine if a rape situation exists . if it is determined that a rape situation exists , the microcomputer 52 will activate the vibrator ring 74 to vibrate and thus alert the user that the female security and rape prevention device 10 has been activated . upon activation of the device , the auditory recording device 72 is activated to record any sounds produced during the rape and the identification dye is caused to be released from the reservoir 50 by the internal surface pressure sensors 44 . the release of the identification dye causes the dye to contact the penis which has penetrated into the cylindrical housing 20 and cause a discoloration to the outer skin of the penis for use in later proving sexual intercourse . any of the identification dye which is not removed with the penis is absorbed by the foam material covering the inner side 34 of the cylindrical housing 20 . when a penis is inserted into the cylindrical housing 20 the frontal pressure sensitive aperture 26 and the ribs 32 extending along the inner side 34 of the cylindrical housing 20 are caused to expand and contract with the insertion and removal forces caused by insertion and pullback of the penis . as the penis is inserted it is also caused to contact the first and second needles 36 and 38 . when these needles 36 and 38 are contacted by the penis a pressure is applied thereto and the needles 36 and 38 cause the internal surface pressure sensors 44 to send a signal indicating an object has been inserted into the cylindrical housing 20 to the microcomputer 52 . the needles 36 and 38 also inject a tissue irritant into the penis causing an irritation of the skin on the penis to form . any additional tissue irritant dispensed within the cylindrical housing 20 is absorbed by the foam material covering the inner side 34 of the cylindrical housing 20 . furthermore , the first and second needles 36 and 38 include a double edged head which acts to retrieve a tissue sample of the penis inserted into the cylindrical housing for future identification purposes . if a surgical glue 104 as illustrated in fig7 is contained within the cylindrical housing 20 it is caused to be dispensed upon pullback of the penis and forms a seal 106 within the cylindrical housing 20 preventing further insertion of a penis and thus preventing any further rape . if an air bag 108 as illustrated in fig8 is contained within the cylindrical housing 20 it is deployed upon pullback of the penis and seals the open front end 22 of the cylindrical housing 20 preventing further insertion of the penis . if neither the surgical glue 104 nor the air bag 108 are contained within the cylindrical housing 20 repeated insertion and pullback of the penis is permitted and any semen deposited within the cylindrical housing is absorbed by the foam material covering the inner side 34 of the cylindrical housing 20 . the female security and rape prevention device 10 thus blocks the cervix of the user and also protects the vaginal surface from bacterial infection , viral infection and semen entry . from the above description it can be seen that the female security and rape prevention device of the present invention is able to overcome the shortcomings of prior art devices by providing a female security and rape prevention device which is able to retrieve evidence of rape and provide evidence for identifying a perpetrator . the female security and rape prevention device includes pressure sensitive sensors responding to pressure applied to a vaginal wall and a microcomputer connected to the sensors for activating the device upon receipt of signals from the sensors indicating vaginal muscle contraction indicative of penile penetration and a double sided needle able to obtain a penile tissue sample upon pullback by the rapist . the female security and rape prevention device is also able to inject a tissue irritant into the penis of a rapist upon insertion into the device is positioned within the vaginal cavity of a female and remove excess tissue irritant and retain a semen sample of the rapist . furthermore , the female security and rape prevention device of the present invention is simple and easy to use and economical in cost to manufacture . it will be understood that each of the elements described above , or two or more together may also find a useful application in other types of methods differing from the type described above . while certain novel features of this invention have been shown and described and are pointed out in the annexed claims , it is not intended to be limited to the details above , since it will be understood that various omissions , modifications , substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention . without further analysis , the foregoing will so fully reveal the gist of the present invention that others can , by applying current knowledge , readily adapt it for various applications without omitting features that , from the standpoint of prior art , fairly constitute essential characteristics of the generic or specific aspects of this invention .
