BACKGROUND OF THE INVENTION

[0002] Embodiments of the present invention generally relate to a spray device and particularly to a spray canister device for the delivery of water, medication, solutions and/or a pharmaceutical formulation to a surface area of a human subject using a bidet or other modern toilet seat system. More specifically, aspects of the present invention provide a method and device for delivering and applying water, medication, and/or a cleaning solution to a region of a human body (e.g., genital or anal area, intimate parts, perianal region).

Description of the Related Art

[0003] People who have problems controlling their urine or bowels and suffer from incontinence are at risk of skin problems around the buttocks, hips, genitals, and the area between the pelvis and rectum (perineum). Excess moisture in these areas may result in skin problems (e.g., redness, peeling, irritation, and yeast infections, etc.), and if the person spends most of his or her day in a wheelchair, or bed, it is likely that bedsores may also develop. Such skin problem may be worse if the person uses diapers and other products, which allow urine or stool to be in constant contact with the skin. As such, special care by cleaning and drying the area right away after urinating or having a bowel movement, and/or cleaning the skin with mild, dilute soap and water then rinsing well and gently patting dry. In addition, moisturizing creams can help keep the skin moist. Also, a skin sealant or moisture barrier, barrier creams or ointments that contain occlusive, barrier-type topical, such as zinc oxide, lanolin, or petrolatum can form a protective barrier on the skin. Some skin care products, often in the form of a spray or a towelette, create a clear, protective film over the skin. A doctor or nurse can recommend barrier creams to help protect the skin.

[0004] There are a wide variety of ointments, creams or lotions known and available in the market for the treatment of diaper rash or incontinence. Most of these products include ingredients that offer some beneficial property to the product, for example, by acting as a water repellant, emollient, neutralizer or antibiotic. Examples of ingredients that are commonly included in such ointments are mineral oil, silicone fluids (e.g. , dimethicone and cyclomethicone), petrolatum, cod liver oil, lanolin, zinc oxide, talc, calamine, kaolin, topical starch and allantoin. For example, Desitin® ointment (Pfizer, Inc.) is probably the most common topical used in treating diaper rash. It contains common barrier materials (zinc oxide and petrolatum) and additionally contains two common skin conditioning agents (cod liver oil and lanolin).

[0005] In applying skin protection paste, ointments, barrier sprays, lotions, solutions, and fluids to an individual's skin. If the individual is alone, this is impossible since an individual cannot adequately apply skin protection fluid onto hard-to-reach areas of his or her own back and bottom. Accordingly, it is necessary to utilize the services of a second individual to apply the skin protection fluid on hard-to-reach areas such as the back and upper neck. Thus, there is a need for using a spray device, which applies a barrier materials, medicated solutions, fluids, protectants, suspensions, or paste to the skin area of a person, to be incorporated into a bidet seat cleaning systems have water spray nozzle for washing and cleaning private parts of the person.
