ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to shower head devices and, more specifically, to a shower head assembly connected to a hand held member by a length of flexible conduit wherein the water supply can be selectively channeled either directly to the hand held unit or into a treatment housing for further processing before going to the hand held unit. The treatment housing contains an antibiotic chamber, filter media and a filter media screen whereby all particulate matter according to the filter media will be retained within said filter media and an amount of antibiotic will be released into the water being controllably ejected through the hand held unit. In addition the shower head assembly has means for measuring and displaying the temperature of the water thereby allowing control of the solution temperature.
Further the hand held unit has a trigger for selectively releasing the rotational member for varying the intensity and pattern of the water.
2. Description of the Prior Art
There are other shower devices designed to remove particles from a water supply. Typical of these is U.S. Pat. No. 5,795,471 issued to Naito on Aug. 18, 1998.
Another patent was issued to Dixon on Mar. 27, 1990 as U.S. Pat. No. 4,911,704. Yet another U.S. Pat. No. 5,549,822 was issued to Ferguson on Aug. 27, 1996 and still yet another was issued on Dec. 7, 1993 to Ducoin et al., as U.S. Pat. No. 5,267,981.
Another patent was issued to Pronk on Nov. 18, 1986 as U.S. Pat. No. 4,623,095. Another U.S. Pat. No. 5,305,476 was issued to Ohyama et al. on Apr. 26, 1994. Yet another U.S. Pat. No. 4,901,765 was issued to Poe on Feb. 20, 1990 and still yet another was issued on Jan. 4, 1997 to DiGlacomo as U.S. Pat. No. 4,000,742.
U.S. Pat. No. 5,795,471 Inventor: Harusuke Naito Issued: Aug. 18, 1998
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.
U.S. Pat. No. 4,911,704 Inventor: Wilbur Dixon Issued: Mar. 27, 1990
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.
U.S. Pat. No. 5,549,822 Inventor: George E. Ferguson Issued: Aug. 27, 1996
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.
U.S. Pat. No. 5,267,981 Inventor: Jacques Ducoin Issued: Dec. 7, 1993
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.
U.S. Pat. No. 4,623,095 Inventor: Frank E. Pronk Issued: Nov. 18, 1986
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.
U.S. Pat. No. 5,305,476 Inventor: Kelichi Ohyama Issued: Apr. 26, 1994
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.
U.S. Pat. No. 4,901,765 Inventor: Frank C. Poe Issued: Feb. 20, 1990
A coupling for being mounted between the threaded end of the arm of a shower through which water flows and the shower head for mixing liquid into shower water. The coupling includes a coupling body having an inlet portion and an outlet portion with a flow path defined therebetween. A mixing chamber is mounted in fluid communication with the flow path through the coupling body which serves to selectively mix liquid such as body lotion with the water. In this regard, a vacuum generated by a venturi serves to draw the liquid into the mixing chamber. The vacuum is selectively controlled by a vacuum actuator which holds the vacuum until the shower is shut off.
U.S. Pat. No. 4,000,742 Inventor: Edward F. DiGiacomo Issued: Jan. 4, 1977
A hygiene device having a plate that is adapted to be mounted on a wall and the like with fittings thereon connected to a source of hot and cold water with a valve for adjusting the amount of hot water to be mixed with the cold water; the mixture then flowing through a fitting mounted on the plate having a slide valve that is normally closed but is opened upon inserting a quick coupler device therein. The quick coupler is provided with a receptacle for containing a medicine and a venturi into which the medicine is permitted to mix with the water that is then discharged through a douche nozzle.
While these shower head devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a device for irrigating wounds which can be attached to a sink, tub, or shower stall. The device has means for directing the water flow through a flexible hose directly to a hand held unit for washing the wound or alternatively the water can be directed through an antibiotic treatment unit wherein the water is filtered and disinfected, further the unit has means for measuring and displaying the temperature of the water prior to transmission of the water through the hand held unit and application to the wound. The hand held unit is equipped with means for pulsing the water and for heating the water prior to application to the wound. An alternative embodiment is also provided wherein a portable enclosure is provided wherein the user can connect the present invention to a water supply such as a lavatory and therein wash a wound.
A primary object of the present invention is to provide a wound irrigation system which can be used for outpatient treatment.
Another object of the present invention is to provide a shower head attachment having the ability to selectively filter tap water and add an amount of antibiotic to said water.
