For use in all portable adult commode chairs, toddler potty chairs and used at all hospitals, convalescent homes or during a natural disaster (flood, hurricane, tornado) and military use. This is a sanitary inexpensive way of disposing of human waste.
Commode chair and portable toilet have several types of liners dispensing in many different applications as shown in prior art. Some dispensing from below the bowl, some on the side, others pulled over the top. All have common problems they are hard to install or do not work as planned. Potty Pick-Ups is simply a clean and sanitary solution to hazardous waste disposal, with a universal application that will fit all commode chairs.
There is a desperate need in today's market for ecological disposable commode chair liners. This present invention with a color activated, removable, highly absorbent pad, releases neutralizing odors while offering an economical, practical function. This present invention serves a genuine purpose for the dignity of the individual users as well as a safe and convenient method of disposal. While the prior arts have some similarities with the present invention, they differ in regards to design, material and fundamental uses. These differences are essential for the effective use of this present invention. The design stipulates a pleated liner bottom, a removal air-laid pad, and a drawstring closure top for sanitary disposal. The material is a biodegradable liner with a detachable air-laid, color activated removal pad, and biodegradable drawstrings. This present invention can be use in a adult commode/toddler portable potty chair. The liner is biodegradable, with a pleated bottom that expands to lay flat on the commode/potty chair bottom. The removable color activated pad has a dual purpose. 1. When it remains attached to the liner it changes color when exposed to urine denoting that the liner has been used and needs to be discarded. If a medical need arises to ascertain the volume of urine or taking a sample for testing the liner can be removed to allow for said use. To safely dispose of biodegradable liner, the drawstrings are pulled in opposite directions to close the top of the liner for safe disposal.
2. Description of Prior Art
Many of the prior patents have complicated mechanisms for installing the liner pulling them through the bottom of the commode or needing a special liner for a given chair. Potty Pick-Ups will fit most all commode chairs in the market place.
As in early U.S. Pat. No. 5,176,672 this product is designed as waste containment unit that is to be worn under your clothing which receives and isolates waste material from the wearer in a U shaped opening pocket opening in a absorbent material.
Another early U.S. Pat. No. 5,3929,644 their design is specifically made for a female's use it has a concave shaped box with an absorbent material in the bottom to absorb liquid waste. This is not a universal unit for multiple usage very one purpose.
The Einbinder U.S. Pat. No. 5,406,650 is designed for use away for a rest-room facilities or the bed ridden and is for urine only with a resealing plastic cap. With handles on the sides of the neck for the user to hold it in place during use.
The Young et al. U.S. Pat. No. 5,531,724 has a one way valve for use as a containment bag having a gel compound to absorb the liquid for use with a catheter with a holster to hold their bag in place.
The Abbott U.S. Pat. No. 6,625,823 B1 is constructed with a flange like collar securely attached along the edge of the opening of the bag member. Having a string looped through holes in the side of the bag as a way of closeting the bag after use.
The Pier et al. U.S. Pat. No. 6,813,786 B1 has a potty chair and bag combination with the extra bag being stored in a compartment under the bowl with no means of securing the opening after use. Having to pull a new liner out while having the used bag still attached.
The Tanaka et al. U.S. Pat. No. 7,101,357 B2 this apparatus you are to sit on but not crush while you sit on it. This is a very complicated containment aperitif to assemble and not very cost effective to the consumer.
Freeman et al. U.S. Pat. No. 6,202,224 this is an expandable, portable commode. The disadvantages: you must purchase the bag and gel pack separately. It must be attached to the top of the opening with a rubber band with the only way of closing is to tie the opening.
Cross et al. U.S. Pat. No. 5,605,161 Disposable urinary container for male and female units geared toward medical usage. Test strips placed in the interior wall are used for diagnostic testing. The test strips are not a usage indicator but medical diagnostic tools. This is a disposable product and is used to direct urine away from the body of the user when urinating in a upright position.
Person et al. U.S. Pat. No. 4,807,308 This apparatus is a nesting toilet and utilizes a bag from an out side source. The disadvantage to the bag indicated, it has no pleating on the bottom of bag, no drawstrings or deodorizer and it does not change color to indicate usage.
Known prior art includes U.S. Pat. No.
