Abstract
Description
Technical Field
[0001] This utility model relates to a multifunctional stoma bag with variable aperture. Background Technology
[0002] Post-operatively, stoma patients need to attach or bind a bag to collect excrement – the ostomy bag. Whether it's a one-piece or two-piece ostomy bag, the problem of it coming off can occur. Furthermore, regardless of how well the surgery is performed, stoma hernias can still occur in some patients due to various reasons. To better address these issues, various stoma care waist and abdomen belts have appeared on the market. While these belts can solve some of the problems of ostomy bag dislodgement and stoma hernias, the pre-drilled holes are fixed. In practice, different patients require stoma waist and abdomen belts of different diameters, and sometimes even the same stoma patient needs different diameter belts due to using different ostomy bag products. To meet the needs of different patients, factories must produce stoma waist and abdomen belts of different diameters and models, and patients also need to prepare multiple sizes and models of waist and abdomen belts, thus increasing the inventory burden for both parties. The existing stoma waist and abdomen belts on the market can be used by stoma patients without lumbar spine or lumbar muscle diseases. However, if the stoma patient also has lumbar spine or lumbar muscle diseases, they cannot use both the stoma waist and abdomen belt and the waist and abdomen belt for treating back pain. Summary of the Invention
[0003] The problem to be solved by this utility model is to provide a multifunctional stoma waist and abdomen bag with variable aperture. When using this multifunctional stoma waist and abdomen bag with variable aperture, stoma patients can select and adjust the size of the reserved hole on the stoma waist and abdomen bag according to their own situation to adapt to their own needs.
[0004] The technical solution provided by this utility model is: a multifunctional stoma waist belt with variable aperture, including an elastic band and Velcro attached to the elastic band. The Velcro is attached to the front and back of both ends of the elastic band. The elastic band is equipped with an annular variable aperture buckle, which includes an outer buckle and a combined inner buckle that engages with the outer buckle. The periphery of the outer buckle is connected to the elastic waist belt. The combined inner buckle is formed by stacking multiple Z-shaped inner buckles with varying diameters.
[0005] A pocket is provided on the elastic band, located below the buckle and attached to the elastic band with Velcro.
[0006] A hand pocket is provided on the front of one end of the elastic band, with the pocket opening located at the end away from the end of the elastic band.
[0007] The elastic band has multiple vertical slots along the horizontal direction, and each slot is fitted with a rigid, arched support strip to support the lumbar muscles.
[0008] This invention employs the aforementioned structure, utilizing a ring-shaped variable-diameter buckle mounted on an elastic band. The buckle consists of an outer buckle and a combined inner buckle that engages with the outer buckle. The outer buckle is connected to the elastic waistband, and the combined inner buckle is composed of multiple Z-shaped inner buckles stacked together with varying diameters. In use, ostomy patients can adjust the size of the pre-drilled hole on the ostomy bag by adding or removing inner buckles, according to their individual needs, to suit their specific requirements.

[0016] See Figures 1-7This utility model discloses a multifunctional stoma waist belt with variable aperture, comprising an elastic band 1 and Velcro 2 (Velcro, also known as hook and loop fastener, is a common connecting accessory on clothing, with a male and female side. One side of the Velcro is made of fine and soft fibers and round fibers, while the other side is made of stiffer hooks and bristles) disposed on the front and back of the elastic band at both ends. The elastic band is equipped with an annular variable aperture buckle 3, which is located at the end of the elastic band with the Velcro. The buckle 3 includes an outer retaining ring 4 and a combined inner retaining ring 5, both of which are plastic circular pieces. The outer retaining ring 4 connects to the elastic waistband. The cross-section of the outer retaining ring is L-shaped or stepped. The combined inner retaining ring 5 is composed of multiple inner retaining rings with varying diameters stacked together. The cross-section of the inner retaining ring is Z-shaped. The inner retaining rings are designed with an outer diameter of 60-100 mm. The outer side of the smaller inner retaining ring overlaps and fits with the inner side of the larger inner retaining ring, and the outer side of the largest inner retaining ring overlaps and fits with the inner side of the outer retaining ring, thus forming an L-shaped buckle 3. By increasing or decreasing the number of inner retaining rings, the buckle hole diameter can be changed to achieve the purpose of selecting different hole diameters according to customer needs. The inner corners of the Z-shaped inner retaining ring and the L-shaped outer retaining ring are concave rounds. The two protruding ends of the Z-shaped inner retaining ring are convex rounds that mate with the concave rounds, so as to have a certain locking effect when the retaining rings are stacked.
[0017] A storage pouch 7 is provided on the elastic band 1. The storage pouch 7 is located at the lower end of the buckle 3 and is attached to the elastic band 1 via Velcro. The main function of the storage pouch is to hold and secure the ostomy bag to prevent it from swaying when filled with excrement.
[0018] When using an ostomy waist and abdomen belt, ostomy patients often find it inconvenient to use one hand to hold the belt's buckle to prevent it from shifting, while using the other hand to grasp the other end of the belt. This invention addresses this by providing a hand pocket 8 on the front of one end of the elastic band 1 (the end with the Velcro on the reverse side). The hand pocket 8 is closed at one end and on both sides of the elastic band, with the opening at the end furthest from the elastic band end. The user holds the buckle 3 and the elastic band end where the buckle 3 is located with one hand, inserts the other hand into the hand pocket 8, and tightens the elastic band 1. Finally, the hand pocket 8 is attached to the elastic band end where the buckle 3 is located. This allows for easy fastening of both ends of the ostomy waist and abdomen belt together using Velcro, and also enables precise adjustment of the tightness and comfort.
[0019] The elastic band 1 has multiple vertical slots 6 along the horizontal direction, and each slot 6 is fitted with a rigid, arched support strip to support the lumbar muscles.
[0020] The buckle is located at one end of the elastic band, the vertical slot is located in the middle of the elastic band, and when the elastic band is wrapped around the patient's waist and abdomen for fixation, the buckle is aligned with the stoma, and the vertical slot is located at the waist.
[0021] This utility model adopts the above-described structure, using a ring-shaped variable-diameter buckle mounted on an elastic band. The buckle consists of an outer buckle and an inner buckle that engages with the outer buckle. The outer buckle is connected to the elastic waistband around its periphery. The combined inner buckle is composed of multiple Z-shaped inner buckles with varying diameters stacked together. Ostomy patients can adjust the size of the pre-drilled hole on the ostomy waistband by adding or removing inner buckles according to their own needs. In use, the ostomy bag is passed through the hole of the combined inner buckle of the ostomy waistband. The elastic band is wrapped around the patient's waist and abdomen, with the buckle aligned with the ostomy site. One hand holds the buckle, while the other hand is inserted into the purse located at the other end of the waistband to adjust the tightness and fasten it. A vertical slot is located at the waist; when needed, a rigid, arched support strip is added into the slot for fixation.
[0022] This utility model of a stoma lumbar support belt significantly reduces factory development, inventory, and patient usage costs by increasing or decreasing the number of internal clasps and changing the buckle hole diameter to meet patients' needs for different stoma lumbar support belt diameters. Furthermore, this utility model uses plastic circular pieces with a certain degree of hardness as external and internal clasps at locations where stoma hernias are highly likely to occur, thereby applying pressure or preventing stoma hernias.
