## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to portable baby sanitizers for cleansing a baby's bottom, and more particularly, the present invention relates to a portable device, which has a pressurizable chamber, that upon demand, will dispense a multiplicity of liquid streams onto, and in order to cleanse and treat diaper rash on, a baby's bottom.
2. Description of the Prior Art
Ever since the convenient use of diapers to control and contain infant waste, a great concern for parents and caretakers alike has been diaper rash. Unfortunately, diaper rash is a common result of wearing diapers and may be caused by any number of reasons. The most general reason for diaper rash is commonly referred to as a friction rash, which is caused by the constant rubbing of the diaper against the infant's skin. The most pronounced areas affected by friction rash are where the elastic of the diapers are too tight. Luckily, this type of rash is quickly curable by frequent diaper changing, airing out of the infant's skin and the use of protective barriers.
There are, however, more severe types of diaper rash that are less easily treatable. These other types of diaper rash, to name a few, include irritant rash, allergic rash, Intertrigo and Seborrhea rash. Particularly, irritant rash is usually caused by prolonged exposure of the infant's skin to stool enzymes. Ironically, a parent or caretaker will generally treat this rash with harsh soaps, baby wipes, detergents or topical medicines that in turn are irritants to the infant. Thus, a concerned parent who is trying to clean the effected area is actually causing more irritation to the infant. As a result, the infant's outer most layer of skin becomes even more damaged.
Once the infant is re-diapered, and because the effected area is concealed from the parent's view, the rash will continue to develop and worsen as the effected area comes into contact with the infant's fecal matter and urine. Since the protective layer of skin has been breached it is inevitable that microorganisms such as yeast or bacteria will eventually invade the damaged skin.
Since the infant's skin has been tainted with microorganisms the rash will be less responsive to the usual treatments. Continuing to air dry the infant's skin is helpful, but having the infant without a diaper on for extended amounts of time presents the problem that the infant may make a mess, which is unsanitary and difficult to clean up. Applying over-the-counter creams to the rash is also a helpful treatment, but in view of the fact that the infant's skin is extremely sensitive, due to the rash, rubbing the cream onto the effected areas of the infant's skin may cause the infant additional pain and suffering. Yet another helpful remedy in treating this more severe type of rash is to wash the infant's skin with warm water or with a mixture of warm water and baking soda. Although this seems to be the most soothing remedy for the infant, it requires the time consuming task of drawing a bath each and every time the diaper is changed, which every parent and caretaker knows is more than quite frequent.
Therefore, it should come as a surprise that a portable baby sanitizer has not been developed and constructed heretofore in the prior art so as to dispense a soothing liquid mixture onto an infant's bottom for the purpose of treating diaper rash. Because a device like this is not in the prior art, it would be desirable to provide a device like this to parents and caretakers of infants.
A prior art search directed to the subject matter of this application in the U.S. Patent and Trademark Office revealed the following Letters Patent:

DESCRIPTION OF THE PREFERRED EMBODIMENTS
It is to be distinctly understood at the outset that the present invention shown in the drawings and described in detail in association with a portable baby sanitizer with air pump is not intended to serve as a limitation upon the scope or teachings thereof, but is to be considered merely for the purpose of convenience of illustration of one example of its application.
Referring now in detail to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is illustrated in FIGS. 1 through 8 a portable baby sanitizer with air pump device 10 constructed in accordance with the principles of the present invention.
As shown in FIG. 1, the sanitizer device 10 is defined by a tank assembly 12, a seat assembly 14 and a stand 16. Particularly, the tank assembly 12 includes a tank 18, an air release 20 and an air pump 22. The tank 18 has a top surface 24, a bottom surface 26, a front surface 28, a back surface 30, a left side surface 32 and a right side surface 34, which are all formed to create a substantially rectangular air-tight storage chamber 36. The tank 18 is made from any durable plastic preferably of transparent or translucent material. While the tank 18 has been described as having a substantially rectangular shape, it should be understood to one skilled in the art that the tank may be of any other suitably designed shape such as spherical, elliptical, oval, etc.
The air release 20 and air pump 22 are both threadedly attachable to top surface 24 of tank 18. The air pump 22 is, as illustrated, a manual hand pump with a cylindrical body 38 and a handle 40. Although a hand pump is described as the best mode, it is conceivable that any other compression device may also be used in a similar fashion such as an electrically driven or foot operated pump. Once the air pump 22 is threaded onto the top surface 24 of tank 18 the cylindrical body 38 of the pump 22 will be located within the storage chamber 36 and the handle 40 will be located exterior to the chamber 36.
The air release 20 includes a shaft 42, a threaded cap 44 and a valve plunger 46. The threaded cap 44 is located at one end of the shaft 42 while the valve plunger 46 is located at the opposite end of the shaft 42. Once the threaded cap 44 of the air release 20 is screwed onto the top surface 24 of tank 18 the shaft 42 and valve plunger 46 will be located within the storage chamber 36. As best seen in the enlarged detailed perspective view of FIG. 7, when the threaded cap 44 is fully engaged the valve plunger 46 sits snugly into a socket 48, which is located on the bottom surface 26 of tank 18, and creates an air-tight seal within storage chamber 36. The socket 48 is placed in a surrounding relationship with an aperture 49 that is located on the bottom surface 26 of the tank 18. The aperture 49 leads directly into and is in fluid communication with the seat assembly 14. Alternatively, any other air release mechanism may used such as an air release assembly including an air release button, valves, an expansion spring and a metal release rod.
The seat assembly 14 includes a seat 50, a fill hole 52 with a cap 53, a removable waste container 54 and a plurality of discharge holes 56, preferably six upwardly oriented discharge holes. The plurality of discharge holes includes a first set of three upwardly oriented discharge holes 56a and a second set of three upwardly oriented discharge holes 56b. The first set of discharge holes 56a are oppositely and symmetrically disposed, across a center hole 66, to the second set of discharge holes 56b. The seat 50 has a top portion 58, a bottom portion 60, a front end 62, a back end 64 and the center hole 66, which has an inner rim 68. The top portion 58 and bottom portion 60 of seat 50 are formed so that an internal reservoir 70 is located within the two portions, as shown in FIG. 6. The top portion 58 is suitably contoured and dimensioned to comfortably receive the bottom end of a seated baby.
The fill hole 52 is disposed onto the top portion 58 of the seat 50 and is located near the back end 64. Male threads of fill hole 52 protrude slightly upward from the top portion 58 of seat 50 and are designed to engage with the female threads of cap 53. The fill hole 52 is a direct opening to the internal reservoir 70.
As shown in FIG. 3, there are six discharge holes 56 located along the inner rim 68 of seat 50. Although six discharge holes are shown, it should be understood by those skilled in the art that any number, more or less, of discharge holes may be incorporated along the inner rim 68 as desired.
Referring to FIG. 5, track rails 72, 74 are mounted onto the bottom portion 60 of seat 50 with one rail being disposed on either side of the center hole 66. The rails 72, 74 are formed with respective channels 75, 77 which are adapted to slidably receive therein the lip edge 76 of removable waste container 54 so that container 54 is positioned directly underneath the center hole 66 of seat 50 in order to catch drain off liquid from the discharge holes 56 and/or waste from a baby.
When the sanitizer device 10 is manufactured the tank assembly 12 and the seat assembly 14 will be preferably molded as a single continuous piece by an injection molding process or the like. In particular, the bottom surface 26 of the tank 18 is joined to the back end 64 and top portion 58 of seat 50. As described previously, the socket 48 located on the bottom surface 26 of tank 18 has the aperture 49 that leads into a corresponding aperture (not shown) located on seat assembly 14 and directly to the internal water reservoir 70. Again, when the threaded cap 44 of the air release 20 is fully engaged the valve plunger 46 fits snugly into the socket 48 and creates an air-tight storage chamber 36 within the tank 18.
Moving along, the stand 16 is designed to receive the fully joined tank assembly 12 and seat assembly 14. Stand 16 has a left vertical member 78 and a right vertical member 80. Each vertical member 78, 80 has a respective front leg 82, 83 and a respective rear leg 84, 85. A first horizontal cross member 81 joins left vertical member 78 with right vertical member 80 at a point substantially near the bottom of front legs 82, 83. Similarly, a second horizontal cross member 86 joins left vertical member 78 with right vertical member 80 at a point substantially near the top of front legs 82, 83. A third horizontal cross member 88 joins left vertical member 78 with right vertical member 80 at a point substantially near the bottom of rear legs 84, 85. Additionally, a platform 90 joins left vertical member 78 with right vertical member 80 at the top rear portion of each vertical member 78, 80. The stand 16 is configured in this manner so as to support the weight of a baby who is seated in the device 10. Therefore, a person of ordinary skill will appreciate that stand 16 may be of any configuration as long as it suitably accommodates or receives the joined tank assembly 12 and seat assembly 14 in the desired operational position, and stably supports the weight of a baby.
Referring back to FIGS. 1 and 2, the bottom surface 26 of tank 18 rests along the length of the platform 90 while the bottom portion 60 of the seat 50 rests partially on top of, and between, the left and right vertical members 78, 80. The placement of the joined tank assembly 12 and seat assembly 14 onto the stand 16 is designed in such a way so that joined tank assembly 12 and seat assembly 14 will not be dislodged from the stand 16 during use.
Additionally, a restraining means 92 for securing a baby onto seat 50 may be attached to either the tank 18 or the stand 16. The restraining means 92 may be a belt with a clasping means such as Velcro, snaps, buttons or clasps. Further, a liquid soap dispenser 94 may be conveniently attached to tank 18 on back surface 30, left side surface 32 or right side surface 34.
During operation of the device 10, a user will begin by unscrewing cap 53 in order to expose fill hole 52 for the purpose of filling the internal reservoir 70 with a desired amount of water, a predetermined mixture of water and baking soda or any other liquid medicaments. The user will then fully engage the threaded cap 44 of air release 20 so that the storage chamber 36 is completely air-tight due to the fact that valve plunger 46 is fully inserted into socket 48. Next, the user will activate the air pump 22 to compress the air within storage chamber 36. Alternatively, a user may unscrew air pump 22 so as to fill storage chamber 36 partially with liquid in order to reduce the amount of compressions needed to pressurize the storage chamber 36.
After the user places the joined tank assembly 12 and seat assembly 14 securely onto the stand 16, and also slides the waste container 54 into the track rails 72, 74 and directly underneath the center hole 66, the user can then safely place the baby onto the seat 50. Once the threaded cap 44 of air release 20 is unscrewed, the valve plunger 46 disengage from the socket 48 and allow the compressed air to force the liquid in the reservoir 70 through the discharge holes 56 spraying the baby's bottom. The distance between the valve plunger 46 and the socket 48, controlled by the amount of turns of the threaded cap 44, will determine the force at which the liquid will spray through the discharge holes 56. When the liquid is fully discharged the user can leave the valve plunger 46 in its disengaged position from the socket 48 and activate air pump 22 to force air through the discharge holes 56. This will help facilitate the drying of the baby's bottom before re-diapering.
In an alternative embodiment as illustrated in FIG. 8, the user can place the joined tank assembly 12 and seat assembly 14, defining the sanitizer device of the present invention as a separate add-on device, onto a seat of a standard toilet bowl instead of placing it onto the stand 16. In particular, seat 50 would rest of the seat of the standard toilet bowl and the back surface 30 of tank 18 would be supported by the front of the tank of the standard toilet bowl. In this embodiment, the user would not have to use the waste container 54 as the liquid drain off would drain directly through the center hole 66 into the basin of the standard toilet bowl. In addition, it should be readily apparent that the sanitizer device is easily portable since it can be packed into a relatively small area of space and then transported to any other desired location.
It is anticipated that the major components in the tank assembly, seat assembly and stand may each be manufactured by injection molding from a high-impact polypropylene or similar durable plastic material.
It should be appreciated by those skilled in the art that the components of the portable baby sanitizer with air pump in the present invention may be made of different sizes and dimensions which can be scaled up so as to accommodate an adult.
From the foregoing detailed description, it can thus be seen that the present invention provides a portable baby sanitizer with air pump device which allows a user to activate a pressurizable chamber, that will dispense a multiplicity of liquid streams onto, and in order to cleanse, a baby's bottom. The sanitizer device includes the pressurizable chamber which has an air pump and an air release valve. The chamber is in direct fluid flow communication with a seat. The seat contains a liquid holding reservoir which dispenses a liquid spray, when the air release valve is engaged, through a plurality of discharge holes that are disposed along the inner rim of the seat. The sanitizer device can be used in conjunction with an independently transportable stand or in conjunction with a standard toilet.
While there has been illustrated and described what is at present considered to be a preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made, and equivalents may be substituted for elements thereof without departing from the true scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the central scope thereof. Therefore, it is intended that this invention not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out the invention, but that the invention will include all embodiments falling within the scope of the appended claims.
