Abstract

A vaginal douche comprises a vaginal douche applicator for introduction in the vaginal canal and a source or supply of douching fluid connected with the vaginal douche applicator. The vaginal douche applicator comprises an applicator body, a head joined to the applicator body and an internal passage for being supplied with douching fluid. Rearward discharge holes and forward discharge holes in the head communicate with the passage and discharge douching fluid into the vaginal canal. The rearward discharge holes face proximally toward the applicator body, and the forward discharge holes face distally and outwardly from the head at an angle. Douching fluid discharged into the vaginal canal is directed proximally along a plurality of external head channels of the head toward a plurality of external body channels of the applicator body. Douching fluid is directed proximally along the body channels toward the vaginal opening for exit from the vaginal canal. The vaginal douche and vaginal douche applicator are used in a method of vaginal douching.
