FIELD OF THE INVENTION 
     This invention is in the field of Personal Hygiene Systems, and more particularly is a douching system that has the features of allowing continuous shower operation while also allowing controllable douching. 
     DESCRIPTION OF THE RELATED ART 
     In the field of Personal Hygiene Systems, many different douching devices are available on the market. These devices typically consist of either a stand-alone device, or a shower attachment device for use in a shower. The typical shower attachment device is used by attaching a douche device in place of, or over, a shower nozzle and then diverting the water flow through the douching device. Examples of these douching devices include those such as described in U.S. Pat. No. 4,642,100 by Kabbaby, in which the full water flow is diverted from showering to douching, or such as the device in U.S. Pat. No. 5,102,387 by Jorde which attaches over the shower nozzle thus using the entire shower water flow for douching. While these types of douche devices do work, they have many drawbacks however. The diversion of the entire shower water flow through the douching device prevents the user from easily controlling the pressure or volume of the douching flow. Furthermore, the diversion of the entire shower water flow through the douching device prevents the user from easily controlling the water temperature from the douching device. Additionally, the diversion of the entire shower water flow prevents simultaneously showering while douching. 
     Therefore, a need existed for a system of easily controlling the pressure or volume of the douching flow. A further need existed for a system of easily controlling the water temperature from the douching device. Yet a further need existed for a system that will allow simultaneous showering and douching. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a system for easily controlling the pressure or volume of the douching flow. 
     A further object of the present invention is to provide a system for easily controlling the water temperature from the douching unit. 
     Yet another object of the present invention is to provide for a system that allows simultaneous showering and douching.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIG. 1, an elevated perspective view of the shower douching system of the present invention is shown (“the system  10 ” hereinafter.) The system  10  is constructed and adapted to be coupled to a plumbing nipple  12  as is conventionally located in a shower or tub installation. Normally, a shower&#39;s plumbing nipple  12  will have a shower nozzle  16  directly connected to it. The shower nozzle  16  is removed and the system  10  coupled in its place. It will be understood by those skilled in the art that the use of the term shower is not limiting herein as the system  10  may also be coupled to a different plumbing nipple such as a plumbing nipple coupled to and used with a tub faucet (not shown herein). It will be further understood that the scope and function of the shower douching system  10  of the present invention will not be detrimentally described or limited by such usage of the present invention with a tub faucet, or other water sources. 
     The system  10  comprises a coupling  44  rotatably connected to the shower water extension tube  14 . The coupling  44  connects the system  10  to the plumbing nipple  12  by screwing onto the shower plumbing nipple  12 . This coupling thereby connects the shower water extension tube  14  of the system  10  to the plumbing nipple  12 . The shower nozzle  16 , previously removed, is connected to the shower water extension tube  14  by screwing the shower nozzle  16  onto the shower nozzle coupling  46 . 
     The system  10  is further comprised of the main douche body  20 . The main douche body  20  comprises the solution reservoir coupling flange  24  to which the solution reservoir  26  is connected. Protruding from the main douche body  20 , located generally proximate to and beneath the shower nozzle coupling  46  is the discharge tube  28 . As will be explained in more detail further on, the discharge tube  28  extends into the main douche body  20 . Connected to the discharge tube  28  is the douche flexible tubing  18 . Located within and extending from the side of the main douche body  20  is the douche control valve assembly  22 , of which the douche control valve operator  34  is shown pointing upwardly thus indicating that the douche control valve assembly  22  is in the off, or non-douche flow, position. 
     Referring now to FIG. 2, a cross-sectional view showing the internal arrangement features of the shower douching system  10  of the present invention is shown. As shown therein, the shower water extension tube  14  comprises a shower nozzle water channel  38  that allows the continuous flow of water from the plumbing nipple  12  (see FIG. 1) to and through the shower nozzle  16 . Located just downstream of the coupling  44  is the eductor water supply channel inlet  40 . The eductor water supply channel inlet  40  is connected to the eductor water supply channel  36 , which is in turn connected to the eductor venturi nozzle  50 , and thence to the eductor mixing chamber  52 . Coupled to the eductor mixing chamber  52  is the douche control valve assembly  22 , to which is coupled the discharge tube  28 . Coupled to the discharge tube  28  is the douche flexible tubing  18 . Further coupled to the eductor mixing chamber  52  is the solution reservoir eductor suction tube  48 , which extends down into the solution reservoir  26 . 
     Referring to FIG. 4, a cross-sectional view of the douche control valve assembly  22  of the shower douching system  10  of the present invention is shown. The douche control valve assembly  22 , in a preferred embodiment, is a ball type valve assembly. However, other types of valves, well known in the art, may be utilized herein without affecting the scope or operation of the present invention. Referring to FIG. 4, it is shown that the douche control valve assembly  22  comprises a ball  30  within a valve body  32 . The ball  30  has a ball channel  31  through the center of the ball  30 . The ball  30  is coupled to and rotated by the douche control valve operator  34 . If the douche control valve operator  34  is aligned substantially horizontal, or parallel to the shower water extension tube  14 , this is the on, or douche flow position, and fluid flow will freely occur through the ball channel  31  of the ball  30 . Conversely, if the douche control valve operator  34  is aligned substantially vertical, or perpendicular to the shower water extension tube  14 , this is the off, or non-douche flow position, and fluid flow through the douche control valve assembly  22  will be blocked by the side of the ball  30 . 
     Referring to FIG. 3, a top view of the shower douching system  10  of the present invention is shown. In a preferred embodiment the system  10  will further comprise a douche flexible tubing storage clamp  42  coupled to the solution reservoir coupling flange  24 . The douche flexible tubing storage clamp  42  is sized and adapted to allow the douche flexible tubing  18  to be securely held and stored by the douche flexible tubing storage clamp  42  when not in use or as desired. 
     Douche Operation 
     To operate the system  10 , the user will prepare the desired douche solution (details not shown herein) according to personal preference, and place this douche solution into the solution reservoir  26 . The solution reservoir  26  is in turn screwed into the solution reservoir coupling flange  24 . The douche control valve operator  34  is checked, or positioned to the off, or non-douche flow, position. Once the solution reservoir  26  is securely seated into the solution reservoir coupling flange  24 , and the douche control valve operator  34  is in the off position, the shower, or tub, water flow and temperature is adjusted by the user, (details not shown herein). The water flow path for showering is from the plumbing nipple  12  via the shower water extension tube  14 , and out the shower nozzle  16 . 
     When the user is ready to commence douching, the user rotates the douche control valve operator  34  to the on, or douche flow, position. The eductor water supply channel inlet  40  will then divert a portion of the water flow that is being supplied from the plumbing nipple  12  (see FIG.  1 ). The diverted water flow is channeled through the eductor water supply channel  36 , to and through the eductor venturi nozzle  50 . The water flow through the eductor venturi nozzle  50  into the eductor mixing chamber  52  will result in a low pressure condition with the eductor mixing chamber  52  due to the venturi effect of the eductor venturi nozzle  50 . The low pressure within the eductor mixing chamber  52  will cause the douching solution within the solution reservoir  26  to be drawn up through the solution reservoir eductor suction tube  48 . The douching solution will be drawn into the eductor mixing chamber  52  where it will become entrained by the shower water flow through the eductor mixing chamber  52 . The combined douching solution and shower water flow will pass out of the eductor mixing chamber  52 , through the ball channel  31  of the ball  30 , and thence through the discharge tube  28 . The combined douching solution and shower water flow will next pass through the douche flexible tubing  18  to the user&#39;s nozzle (not shown herein.) Throughout the entire time frame from pre-douching, through douching, and after douching the shower water flow is in operation through the system  10 , and out the shower nozzle  16 . This functionality allows the healthful uninterrupted cleansing of showering before, during, and after douching. 
     Therefore, throughout the use of a preferred embodiment of the system  10  of the present invention, the shower flow will be easily controlled thus supplying a substantially constant pressure and volume of both the shower flow and the douching flow. Furthermore, the water temperature through the system  10  will remain substantially constant. And finally, a preferred embodiment of the present invention will allow simultaneous showering and douching by the user. 
     Although the invention has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that changes in form and detail may be made therein without departing from the spirit and scope of the invention.
