Abstract

An ostomy system comprising a stretchable belt and a disposable ostomy unit. The stretchable belt comprises a band of stretchable material, a reinforced ring opening, a belt pouch surrounding the reinforced ring opening and belt fasteners. The disposable ostomy unit is comprised of an absorbent wafer and a waste bag that are adhesively connected together, where the absorbent side of the wafer faces the user's skin and the distal side of the wafer is adhesively connected to a circular flange of the waste bag. In use, the waste bag of the disposable ostomy unit is inserted through the reinforced ring opening of the stretchable belt and into the belt pouch until the reinforcing ring opening abuts against the circular flange of the waste bag. The disposable ostomy unit is then aligned with the stoma and placed on the peristomal skin. The absorbent wafer does not have skin adhesive on the skin side surface. The disposable ostomy unit is secured in the correct position on the peristomal skin by fastening the stretchable belt around the user's torso using the belt fasteners, where the reinforced ring opening of the stretchable belt applies pressure onto the circular flange of the waste bag, the absorbent wafer and persitomal skin.

Description

DISPOSABLE OSTOMY DIAPER SYSTEM

This invention relates to ostomy care management, more particularly a disposable ostomy diaper system.

Ostomy surgery patients (intended users) use ostomy pouches for body waste discharge management in their daily life. For decades, many forms of ostomy pouch systems have been developed by various companies. At present, there are two major types of ostomy pouch systems available; the drainable one piece system where the waste collection pouch is attached to a base-plate (or wafer so called) permanently, and two piece system where the waste collection pouch is attached to the base-plate by mechanical coupling or other means so that the waste collection pouch is exchanged without changing the base-plate. For both one-piece and two-piece ostomy pouch systems, the base-plate, which has a center opening corresponding to the size of stoma, is attached to peristomal skin by adhesive.

Both systems mentioned above require high level maintenance in terms of prevention of pouch leakage and peristomal skin complications. Numerous details have to be addressed when carrying out procedures such as preparing precision cutting the center opening of base-plate to fit the size of stoma, filling up cavities of deformed peristomal skin with sealing paste sealing strips, putting barrier on peristomal skin to prevent possible skin damages caused by both adhesive’s direct contact to peristomal skin and/or erosion by body waste discharge and its moisture seeping under the adhesive bonding, tearing off base-plate from peristomal skin, cleaning adhesive residue when changing new pouch, etc. Any ignorance of the above mentioned details will result in pouch failure which could leads to various forms of peristomal skin complications such as reddening, swelling, rash, infections and even ruptures of peristomal skin of intended users. For drainable pouch system, pouch rinsing, the procedure each intended user performs several times in a day, could be cumbersome when dexterous coordination is required in handling the squirting bottle to rinse out body waste discharge with the pouch attached to the body of intended users.

Moreover intended users have to deal with psychological frustrations of their body image change because it is very difficult to dress properly for various social occasions like normal people with the space occupation of ostomy pouch underneath their clothing. Even taking a daily shower becomes a serious undertaking because they have to worry about soaking of the pouch which could result in weakening of the adhesive bonding strength of the base-plate, and awkwardness to move around with ostomy pouch attached. So there is a demand for an ostomy care system that requires low maintenance without compromising the functions for body waste discharge collection and disposal.

The invention of disposable ostomy diaper system addresses the foregoing issues and provides practical solutions in resolving those issues. The disposable ostomy diaper system comprises both a disposable ostomy diaper unit, which is used for both collection and disposal of body waste discharge, and a stretchable belt with holding pouch, which holds the disposable ostomy diaper unit in place in maintaining reliable sealing between the disposable ostomy diaper unit and peristomal skin of intended users. Compared with current available ostomy pouch systems, this disposable ostomy diaper system eliminates the use of adhesive in attaching the ostomy diaper unit to peristomal skin of intended users so that requirements for skin care and related preparing procedures are significantly reduced. Additionally, the hygiene conditions for stoma and peristomal skin are significantly improved by thoroughly cleaning each time when the disposable diaper unit is changed. Easy and fasting change and disposal of the disposable diaper unit is possible even without access to water. It is an affordable system for many intended user population in both developing and under developing countries and regions compared with other available ostomy pouch systems.

The descriptions and references of the invention of disposable ostomy diaper system are presented here in detail to the current preferred embodiments of this invention as illustrated in appended drawings.

The disposable ostomy diaper system comprises a disposable ostomy diaper unit (Fig.1), and a stretchable belt with holding pouch (Fig.2).

The disposable ostomy diaper unit comprises, as shown in Fig.1, a disposable pouch 20, a flange with neck stub 30, and a moisture absorbent pad with a center opening 10. Said disposable pouch 20 is made of water proof materials, such as plastic, rubber, or fabrics with waterproof lining. Said flange 30 is made of flexible sheet materials, such as plastic, urethane, or glossy paper board stock which can accommodate the contoured body shape around stoma so as to maintain reliable sealing between the disposable ostomy diaper unit and peristomal skin of intended users. From the standpoint of mass industrial manufacturing and cost control concerns, thermal plastic, such as PVC, PE and PP, are recommended to use for both said disposable pouch and said flange with neck stub. The moisture absorbent pad 10 with center opening 12 is constructed with nonwoven top surface 14 and adhesive coated bottom surface 15 of water proof materials with water absorbent fibers in between both the same structure as feminine sanitary pad.

As shown in Fig.4, the circumference of opening 21 of said disposable pouch 20 fits the outside diameter of the neck stub 31 of said flange and is thermal bonded therein to serves the purpose of collection of body waste discharge through stoma of intended users.

The flange with neck stub 30, when assembled with both disposable pouch 20 and moisture absorbent pad 10, serves the purpose of holding disposable ostomy diaper unit in place with the stretchable belt 40 by fitting the neck stub 31 of said flange 30 with the opening of fixture washer 43 on said stretchable belt 40. The neck stub 31 of said flange 30 protects stoma of intended users against unexpected external force and at the same time provides secured passage for body waste discharge from stoma of intended users flowing into said disposable pouch 20 without blogging when the disposable ostomy diaper system is in use.

As shown in Fig.3, said moisture absorbent pad 10 has a center opening 12 of 30 mm in diameter and 6 radial incisions 13 evenly spaced with an outside boundary of 50 mm in diameter to accommodate different sizes of stomas of intended users; such a design of center opening 12 of said moisture absorbent pad 10 helps to stop back flow of body waste discharge without blogging the inflow and makes it possible to preassemble the disposable ostomy diaper unit by manufacturers so as to save intended users from the hassle of custom preparing the said unit before use. The top surface 14 of said moisture absorbent pad 10 has direct contact with peristomal skin and provides reliable sealing between the disposable ostomy diaper unit and the peristomal skin when said stretchable belt is fastened with Velcro fasteners.

The thermal bonded assembly of said disposable pouch 20 and said flange with neck stub 30 is bonded with said moisture absorbent pad 10 by putting together the top surface 33 of said flange 30 with the adhesive coated bottom surface 15 of said moisture absorbent pad 10 with concentric alignment of their center openings, thereafter four adhesive coated wings 11 on said moisture absorbent pad 10 are to be bonded on the underside32 of said flange 30 with neck stub to reinforce bonding unity of said disposable ostomy diaper unit to prevent leakage.

The stretchable belt 40, made from synthetic fibers and elastic elements, has an opening, which fits with the outside diameter of the neck stub 31 of said flange 30, cut about 300 mm from the end where the pad 41 with locking loops of Velcro fastener is attached so that both the fastening and unfastening of said stretchable belt 40 can be done easily in the front of body of the intended users.

As shown inFig.5, a fixture washer 42 of nonstretchable fabric is stitched on the inside opening of said stretchable belt 40 for keeping the dimension of the opening of said stretchable belt unchanged when said belt 40 is fastened in order to hold a secured fitting with the neck stub 31 of said flange 30 of the disposable ostomy diaper unit.

The holding pouch 43 is made of knitted stretchable synthetic fabric. Said holding pouch 43, which is stitched on the outside opening of said stretchable belt 40, houses said disposable pouch 20 of the disposable ostomy diaper unit and conceals it cosmetically. For reinforced sealing between said disposable ostomy diaper unit and peristomal skin, the length of the holding pouch 43 on said stretchable belt 40 is 30 mm shorter than that of disposable pouch 20 of said disposable ostomy diaper unit so that the weight of said disposable ostomy diaper unit, when filled with body waste discharge, is carried by said holding pouch 43 without pulling the disposable ostomy diaper unit away from peristomal skin. The combination of stretchable holding pouch 43 and extra length of the disposable pouch 20 gives an extra buffer volume in order to accommodate any unexpected excessive body waste discharge of intended users, for instance in case of diarrhea, so that the intended users can change the disposable ostomy diaper unit time in without dealing with possible body waste discharge spillage.

The length of stretchable belt 40 is designed to accommodate the circumference of the waist where the stoma of intended user is located in such a way that, with 10 to 15% elongation of the belt for chosen stretchable band material, the said stretchable belt 40 will apply holding pressure onto the flange 30 of the disposable ostomy diaper unit for a reliable sealing between said disposable ostomy diaper unit and peristomal skin of intended users.

How to Use

For the convenience of intended users, it is recommended that each intended user keep two or three said stretchable belts in possession for both alternate use and cleaning on regular basis. Preferably, use two belts alternately in such a ways that when one belt is in use the other one has the disposable ostomy diaper unit installed so that both changing and disposal of used disposable ostomy diaper unit can be done quickly without hassle.

Procedures for Putting on the disposable ostomy diaper system

Step 1. When in use, put said disposable ostomy unit into the holding pouch of said stretchable belt with the neck stub of said disposable ostomy diaper unit fitting securely with the opening of the holding pouch of said stretchable belt.

Step 2. Align the center of the opening of said the moisture absorbent pad with the orifice of stoma and attach it on peristomal skin.

Step 3. Fasten the belt by putting both loop and lock pads of Velcro fastener together.

Step 4. Make adjustment to ensure the tension of said stretchable belt evenly distributed along the length of said belt to prevent position shifting of said disposable ostomy diaper unit due to the slipping of said stretchable belt. When fastened, said stretchable belt applies holding pressure onto the flange of said disposable ostomy diaper unit to achieve secured and reliable sealing.

Procedures for changing disposable ostomy diaper unit

Step 1. Have the spare stretchable belt with disposable ostomy diaper unit installed on sight.

Step 2. Put one hand to hold said stretchable belt around holding pouch to prevent said stretchable belt from falling off when unfastened.

Step 3. Release the Velcro fastener and take the whole assembly of disposable ostomy diaper system off and put it on a staging place.

Step 4. Clean thoroughly both stoma and peristomal skin with disposable wet towels and/or bathroom tissues and mild soap.

Step 5. Follow step 2 to step 4 from procedures for putting on disposable ostomy diaper system

Step 6. Separate the used disposable ostomy diaper unit from the stretchable belt by lifting the edge of the used disposable ostomy diaper unit and pull it off from holding pouch of the stretchable belt. Dispose body waste discharge content into toilet and put the used disposable ostomy diaper unit in a garbage bag for disposal

Care and Application Tips

It is recommended to clean the stretchable belt with holding pouch every week if two belts are used alternatively. When cleaning, soak said belt in warm water with clothes washing detergent and soft brush to scrub the belt thoroughly, rinse clean and hang to dry. If drying with drier, keep said belt fastened to prevent both loops and hooks of fasteners from damages due to tumbling and make sure to set the drier at low temperature setting because high heat would change the physical properties of synthetic materials.

Foul odor due to gas release and delayed change of disposable ostomy diaper unit when filled with body waste charge can be offset temporarily by using deodorant spray inside of the holding pouch before fitting the disposable ostomy diaper unit on to the holding pouch of the stretchable belt. It is recommended to change the disposable ostomy diaper unit in time after each body waste discharge.
