Enema device and a method of refilling said device with an enema

An enema device comprising a delivery container and an applicator nozzle, wherein said delivery container comprises two distinct cavities, an outer cavity defined by a squeezable external body, and an inner cavity defined by an inner flexible bladder, and wherein one of said two cavities is communicating with an outlet for dispersing an enema though the applicator nozzle and another one of said two cavities is communicating with surroundings via an air inlet, wherein the cavity communicating with the air inlet is arranged for becoming larger during intake of air, and the cavity communicating with the outlet is arranged for becoming smaller during intake of air, whereby an enema contained in the cavity communicating with the outlet is displaced towards said outlet, and wherein an increase in volume of the cavity communicating with the air inlet causes a corresponding reduction in volume of the cavity communicating with the outlet, such that expansion of the cavity communicating with the air inlet compresses the cavity containing the enema to displace the enema toward the out let, and wherein a first nonreturn valve is placed in communication with the outlet, and/or a second nonreturn valve is placed in communication with the air inlet.
