Description:
BACKGROUND OF THE INVENTION  
         [0001]    A substantial amount of research has been conducted and reported emphasizing the physiological and psychological benefits of sexual activity including sexual activity between partners as well as masturbation. Most physicians believe that masturbation is healthful as long as religious, moral, and psychological concerns—fear of sin or feelings of guilt—can be put aside. Some of the reports indicate that ejaculation and orgasm three times a week is healthful. Even once or twice a week, sex increases levels of immunoglobulin and thereby helps prevent tension and possible other illnesses. Some of the reports have indicated that sex once a day might add several years to a man or woman&#39;s life. Most of these authorities do not specifically state that solo masturbation is as helpful as is sexual intercourse with a partner, but masturbation is increasingly viewed not only as a response to the loss of sexual contact with a partner, but also as a natural and ongoing supplemental activity within a relationship. It is generally thought that masturbation as well as sexual intercourse reduce tension and stress in both men and women.  
           [0002]    There have been many devices developed for providing blood engorgement of both the penis for men and the clitoris of women to aid them in sexual activity with a partner. Some of these attempts are disclosed in the following patents: U.S. Pat. Nos. 6,099,463; 4,856,498; 4,378,008; 3,744,486; 1,225,341; 6,036,635; 5,115,800; and RE 36,958. In addition to the patents, there are numerous articles discussing the problems with erectile dysfunction and the fact that sexual activity has both physiological and psychological benefits. As reported there are many persons, especially older men and women, who suffer from erectile dysfunction.  
           [0003]    Accordingly, it is an object of the present invention to provide an apparatus which aids a user in obtaining an erection to facilitate masturbation in an attempt to have an orgasm.  
         SUMMARY OF THE INVENTION  
         [0004]    A device for aiding and stimulating blood flow in the sexual organ of a user leading to an erection for facilitating masturbation. The device may be used by both men and women, and when reference is made to a sexual organ in the claims and in the specification hereof, it could include both the penis of the male and the clitoris of a female.  
           [0005]    The device includes a chamber adapted to receive and enclose a user&#39;s body from adjacent the waist of the user to adjacent the upper thighs. The chamber includes a front wall and a rear wall joined by side walls, a top, and a bottom wall. The rear wall has two openings through which the legs of the user extend. The front wall has a main opening for allowing the user to insert his lower body into the chamber allowing the user&#39;s legs to extend through openings in the rear walls. A source of vacuum is coupled to the chamber for creating a negative pressure within the chamber. Arm openings are provided in the front wall through which the user&#39;s arms extend in order for the user to touch and/or massage his/her sexual organ. Air seals are provided between the openings in the rear wall and the user&#39;s legs and similar air seals are provided between the main opening and the user&#39;s body and the arm openings and the arms of a user.  
           [0006]    Once the user extends his torso into the chamber with his legs extending out the rear, he inserts his arms through the openings provided in the front wall to touch and manipulate his sexual organ to initiate sexual arousal. After sexual arousal begins, a switch is operated to turn on a vacuum pump to place a negative pressure within the chamber. When a negative pressure is applied to the chamber, it assists in causing the engorgement of blood into the penis or clitoris of the user to produce an erection. Once an erection has occurred, the user through manual manipulation either by the hands or any other suitable mechanical tool manipulates the sexual organ until ejaculation and/or orgasm occurs.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0012]    Referring in more detail to FIG. 1 of the drawings, there is a device for aiding in stimulating blood flow into the penis of a male or the clitoris of a female. Such is accomplished by producing a negative pressure over the user&#39;s body in the housing extending from about the waist to the thighs. After the user has performed preliminary manipulation of his sexual organ, the chamber is placed under a vacuum which causes the walls of the corpora cavemosa to distend and overfill with blood. The engorgement leads to a very hard erection of the penis or clitoris usually within one or two minutes. The apparatus includes a chamber generally designated by the reference character  10  into which a user extends his body. The chamber  10  for purposes of comfort, is inserted between two mattresses  12  and  14  so that the user&#39;s body can extend conveniently through the openings provided in the chamber. Suitable pillows  16  are provided for additional comfort to the user to aid him in lying in a supine position.  
         [0013]    The chamber includes a front wall  18  and a rear wall  20  joined by side walls  22  and  24 , a top  26 , and a bottom  28 . The rear wall has a pair of openings  32  provided therein through which the user&#39;s legs extend. Only one of the openings is shown.  
         [0014]    A main opening  34  is provided in the front wall  18  for enabling the user to insert his torso through the housing. The opening  34  is of sufficient size to permit the hips to pass therethrough into the interior of the chamber and to extend around the waist portion of the user. Two additional openings  36  and  38  are provided in the front wall  18  for permitting the user to insert his arms therethrough into the cavity of the chamber. In order to provide a substantially sealed chamber, a latex sheet  39  is attached by any suitable means to the front wall and has a centrally located opening  40  that extends over the opening  34  in the front wall. It also has a pair of openings  42  and  44  provided therein that extend over the openings  36  and  38  respectively for permitting the arms of the user to pass therethrough. As a result of the latex material being elastic and flexible when the arms of the user and the torso are inserted through the holes therein, a seal is produced around the arms and torso. The opening  40  in the latex sheet  39  has a flap portion  46  that is joined adjacent the lower side of the opening so that it can be pulled down by any suitable means such as a strap  48  when the user is inserting his body therethrough.  
         [0015]    The latex sheet  39  provides a seal over the front wall of the chamber. An additional latex member  50  is attached to the rear wall of the chamber and has circular openings  51  provided therein which are slightly smaller than the openings  32  provided in the rear wall so as to produce a seal around the thighs once they are inserted therethrough. The elastic flexible sheet  50  may be attached to the rear wall in any suitable manner such as through taping or by adhesive.  
         [0016]    While it is shown that a latex sheet is being used to provide seals around the openings for receiving the arms, torso, and legs, it is to be understood that other suitable sealing members could be used such as an inflated flexible rubber tubular member or elastic material as long as it provides a seal around the legs, torso, and arms when a negative pressure is applied to the interior of the chamber.  
         [0017]    A negative pressure is produced in the chamber by a vacuum pump  52  for evacuating air from the chamber that has a pressure gauge  54  connected to the conduit  56  that is attached to the side wall of the chamber. Any suitable electrical switch can be used with the vacuum pump for turning the vacuum pump on. A foot operated switch is preferred since it does not require the user to remove his arms from the chamber.  
         [0018]    A transparent viewing window  68  is provided in the front wall  18  of the chamber for permitting the user to see inside the chamber. The viewing window  58  is shown in the latex sheet  39 . The transparent viewing window  58  however, could be inserted in the front wall opening  68 . If this is the case, then it would be necessary for the latex sheet to be secured to the front wall slightly below the viewing window  68 . The viewing window  58  may be constructed of any suitable transparent material that can be attached to the latex sheet  39  by any suitable adhesive means. A battery operated light  63  is provided on top of the chamber for illuminating the inside of the chamber. Since users of the apparatus will be of different sizes, in order to aid in producing positive seals around the users torso, a baffle plate  60  can be inserted between the front wall  18  and the flexible sheet  39 . The baffle plate  60  has a contoured cut out  62  which produces a closer fit with the abdomen and the ribs of the user. Such minimizes the chance that the flexible elastic sheet  39  will be involuted into the chamber by the negative pressure. Other types of baffle plates could be utilized, and while the baffle plate as shown in FIG. 5 is attached to the front wall by a screw or peg, it is to be understood that baffle plates could be supported between vertically extending tracks so that it could be lowered and raised by the user after inserting his body into and before taking his body out of the chamber. As can be seen in FIG. 2, the openings in the front wall shown in phantom lines are larger in diameter and length than the openings provided in the elastic flexible sheet  39  so that the sheet  39  is pulled securely around the arms and the torso of the user to provide an air seal. It has been found that the preferred negative pressure in the chamber should be approximately −160 mmHg. While a −160 mmHg is the preferred pressure, it has been found that a pressure between a −120 mmHg to a −210 mmHg is suitable.  
         [0019]    While the chamber has been shown to be constructed in a single unitary housing having a top, side walls, and a bottom, it is to be understood that the chamber could be constructed into separable portions such as a bottom half and a top half that are secured together by any suitable means such as a hinge connection that permits the chamber to be closed around the user&#39;s body when he is positioned therein. This would require different types of seals from the flexible elastic sheets shown but it is to be understood that any suitable seals could be used for providing a seal around the limbs and the torso of the body.  
         [0020]    Handles  70  are provided on the side walls for permitting the user to grip when pulling his body into the chamber.  
         [0021]    In operation, when a user desires to use the device for aiding in obtaining an erection in his penis, he slides his legs through the opening  40  provided in the sheet  39  while pulling the flap  46  downwardly with the straps  48  over his buttocks. Once the user pulls himself into the chamber so that his legs extend out the rear of the chamber and the front wall  18  is located approximately at his waist, he is in a position to begin the mental foreplay that is preferred prior to applying suction to the chamber. This mental foreplay can include stimulating photographs and/or manually manipulating the sexual organ with his hands. Once the user becomes manually stimulated, he depresses a switch with his foot or any other means to turn on the vacuum pump. The vacuum pump creates a negative pressure within the chamber that increases blood flow into the penis that produces an erection. At this point in time, the user can masturbate to obtain an orgasm or if he prefers, he can place a restrictive device such as a rubber band on the penis adjacent the junction of the body so as to hold the penis in an erected position to enable him to complete the sexual activity with a partner.  
         [0022]    While the above description has been primarily related to a male and the penis sexual organ, it is to be understood that the same procedure could be used by a female permitting her to have an erection of the clitoris by means of blood trapped therein when exposed to the negative pressure in the chamber.  
         [0023]    While the chamber  10  as shown in the drawings is a substantially rectangular shaped chamber, it is understood that the chamber that includes the top and side walls could be made in tubular shape. An elongated tubular pipe of substantially the same diameter as the height of the chamber could be utilized with front and rear walls through which the user inserts his torso, arms, and legs. If such were the case, it would still be desirable to have a viewing window in the front wall to allow the user to see inside the chamber.  
         [0024]    The dimension of the chamber could be varied to accommodate persons of different sizes.  
         [0025]    If it is preferred that the viewing window  58  should be in the front wall  68  rather than in the latex sheet  39 , then the height of the front wall should be increased to provide adequate space between the viewing window  68  and the openings  36  and  38  for the arms to permit the latex sheet  39  to be attached to the front wall. In one particular application, the latex sheet  39  is attached to the front wall by “duct tape”.  
         [0026]    While the preferred embodiment invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
