[0009] A shower device having a water purifying function includes a cartridge type filter formed with a water inlet at one end and a water outlet at the other end and means for showering such a shower head connected to the water outlet of the cartridge type filter. The cartridge type filter contains a tannin layer consisting of a material comprising tannin, a bakuhanseki layer consisting of granular ceramic formed in a layer, a magnetite layer consisting of broken pieces of magnetite formed in a layer and provided at least on the water inlet side of the ceramic layer, and magnetizing means such as magnets for magnetizing the magnetite layer.

[0010] Apparatus attached to a shower head for cleansing parts of the body with a stream of medicated liquid. The apparatus includes a control valve assembly between the water supply pipe and the shower head and a flexible hose having one end connected to the control valve. The other end of the flexible tube lies within an elongated cylindrical mixing chamber with a small hole in the tube spaced from the end of the tube also lying with the mixing chamber. The forward end of the cylindrical mixing chamber is sealed by the swiveable ball-shaped end of a dispensing nozzle from which a mixture of water and medicant is discharged.

[0011] The water purification filter is coupled intermediate any conventional shower head feed pipe and shower head. The filtration device is toroidal with a serpentine flow path. The filtration device envelopes the feed pipe which enables the shower head to remain within substantially the same location as before the insertion of the filter. To purify the shower water, the filter contains a filter media coupled between two filter screens.

[0012] A hygiene and treatment device wherein it comprises a pipe having a chamber at one of its ends, suitable for being put into communication with an end piece connected to a supply of water under pressure, the other end of the pipe being curved and having a longitudinal slot. The invention is particularly suitable for anal and gynecological hygiene.

[0013] A device to air entrain and add liquid soap or some other liquid to the water stream which flows through a shower head. There is a secondary liquid additive passageway leading into a constructed reduced pressure area of the main flow passageway of the shower water. There is a container rotatably mounted in a manner to either shut off flow of the liquid soap or other liquid, or to selectively meter the flow into the main water stream by selectively aligning aspirating air holes with an aspirating air passageway that leads into the secondary passageway.

[0014] A shower bathing device comprising a passage through which hot water is passed, a chamber filled with a medical solution to supply the medical solution into the passage, a stream pump for mixing the medical solution in the chamber with hot water passing through the passage, and a screw inserted into a through hole for adjusting the amount of medical solution supplied to the stream pump, wherein hot water can be showered while including a desired density of medicine therein.
