Description

Technical Field

[0001] This utility model relates to the field of perianal ostomy bags, and more particularly to a novel perianal ostomy bag for adults. Background Technology

[0002] Anal ostomy bags are widely used in clinical practice as routine medical consumables, with their core function being to collect excrement and protect the integrity of the skin around the stoma. However, the application of existing ostomy bags has significant limitations in meeting the perianal care needs of critically ill patients (such as those with prolonged bed rest, acute diarrhea, or intestinal failure), and there is an urgent clinical need for technological innovation.

[0003] Traditional nursing methods (such as tea oil, diaper rash cream, and zinc oxide ointment) offer some protection to the skin barrier, but they cannot address the continuous irritation caused by the high frequency of loose stools (usually >8 times / day) in severely ill patients. Digestive enzymes and inflammatory mediators in the excrement can easily penetrate the existing protective layer, triggering incontinence-associated dermatitis (IAD), with an incidence rate exceeding 85% in patients with severe diarrhea. Existing negative pressure drainage devices and ostomy bags are designed as separate units, which are not securely fixed and are prone to falling off. The rigid interface can easily cause ischemic damage to the skin and mucous membranes due to prolonged pressure. The circular base can easily cause damage to the gluteal cleft, requiring the ostomy bag to be changed every 2-4 hours to prevent leakage. However, repeated tearing and pasting cause stratum corneum peeling, exacerbating the skin damage rate (clinical data shows that the risk of IAD increases by 17% with each additional change).

[0004] Existing ostomy bag base adhesives contain irritating adhesives, causing secondary damage to already broken skin. When the amount of loose stool / mucus exceeds 500ml / day, traditional ostomy bags are prone to bursting due to excessive bag tension, with a leakage rate as high as 32%. Critically ill patients often experience intestinal distension (abdominal pressure >15mmHg), and existing ostomy bags lack a pressure release mechanism, leading to bag bulging and detachment or backflow infection. Thick feces easily adhere to the inner wall of the bag, making cleaning time-consuming and increasing the workload of nursing staff (average daily nursing time >1.5 hours / patient). Furthermore, existing devices lack the function of monitoring excrement characteristics, affecting the efficiency of clinical decision-making. Utility Model Content

[0005] Therefore, to address the aforementioned problems, this utility model proposes a novel perianal ostomy bag for adults. It solves the technical problem of poor nursing effect of perianal ostomy bags.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel adult perianal ostomy bag includes a bag body, a base disposed on the bag body, the base having an adhesive backing, and a perianal opening on the base that leads to the bag body. The bag body has a flushing tube, which includes a water inlet located outside the bag body and at least one water outlet located inside the bag body. The bag body has a sampling window with an opening and closing door. The bag body has a suction port with a valve, and the bottom of the bag body has a drain port that can be sealed by a sealing element.

[0008] Further:

[0009] The rinsing pipe is located around the perimeter of the bag, and there are at least three water outlets. The water inlet of the rinsing pipe is covered with a cap.

[0010] The sampling window is located on the opposite side of the perianal opening, and the position of the sampling window corresponds to the position of the perianal opening.

[0011] The aperture of the perianal opening is not less than 35mm, and the sampling window is a square structure with a side length of 20mm.

[0012] The base has a thickened section at the top near the hip.

[0013] The valve is opened and closed by rotation, and the valve is connected to a suction tube.

[0014] A cap is connected to the end of the suction tube.

[0015] The base has a heart-shaped structure, and the adhesive backing has multiple annular scale lines at the perianal opening. The base has multiple cutouts along its periphery.

[0016] The bag body is provided with an exhaust port, and the exhaust port is provided with a waterproof membrane. The waterproof membrane is breathable but not liquid-permeable, and an activated carbon layer is detachably provided on the outside of the waterproof membrane on the exhaust port.

[0017] The bottom of the bag is provided with a folding part, and the sewage outlet is located at the lower end of the folding part. The sealing element includes a bending strip, a first double-sided adhesive in the middle of the bending strip, and a second double-sided adhesive at both ends of the bending strip. The first double-sided adhesive is fixed to the lower edge of the folding part. The folding part can be flipped upward at least twice to wrap the middle of the bending strip. The two ends of the bending strip are bent inward so that the second double-sided adhesive can be attached and fixed to the bag body.

[0018] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0019] This utility model features a flushing tube on the bag body, which effectively removes viscous excrement adhering to the bag wall and around the stoma, extending the ostomy bag's lifespan, reducing replacement frequency, and improving cleanliness. The flushing tube is fixed to the bag's edge, providing support and cushioning to prevent displacement or damage. A sampling window allows for sampling, reducing contamination. Feces collected inside the bag can be directly suctioned away through the suction port valve, reducing the need for bag replacements. For patients with diarrhea, characterized by loose and copious stools, continuous negative pressure suction can reduce bag detachment and improve cleanliness. Furthermore, at least three water outlets distributed around the perimeter form a ring-shaped flushing channel, working in conjunction with the water inlet to achieve 360° cleaning without dead angles, effectively removing viscous excrement adhering to the bag wall and around the stoma, significantly reducing the risk of enzymatic skin damage. Additionally, the breathable surface layer provides both ventilation and air release, preventing excessive or insufficient gas inside the ostomy bag and preventing the accumulation of harmful gases that could affect patient recovery. Furthermore, the 20mm... 2 The sampling window allows for rapid acquisition of excrement samples, enabling non-invasive monitoring in conjunction with a breathable surface layer, thus shortening the clinical decision response time. Furthermore, the heart-shaped base expands the contact area, and the 35mm large-diameter design accommodates patients of different body types, reducing the time required for a single nursing procedure. Furthermore, the thickened section reduces shear force on hard edges, and the heart-shaped structure disperses pressure, lowering the incidence of pressure injuries to the skin around the stoma. Furthermore, the fully enclosed drainage system and negative pressure drainage form a physical isolation barrier, reducing the risk of retrograde infection. Finally, the sealing element is fixed by folding, making assembly and disassembly convenient and quick. Attached Figure Description

The perianal opening 22 is located at the patient's anus, and the patient's excrement can be discharged into the bag 1 through the perianal opening 22. During sampling and testing, the opening and closing door 12 can be opened, and cotton swabs or other sampling devices can be used to collect samples through the sampling window 11. This is quick, convenient, and less likely to cause contamination. During cleaning, the second double-sided adhesive 43 of the bending strip 41 is torn off, and the folding part 18 is rotated to unfold the bag 1. The excrement can be discharged through the drain port 15 at the bottom of the bag 1. The water inlet port can be connected to a water pipe, and water can be used to clean the excrement in the bag 1 through the water outlet 32. The bag 1 can then be reused. When the stool is loose or plentiful, the valve 14 can be opened, and the suction tube 16 can be connected to the adsorption device. The adsorption device will clean the excrement adhering to the bag 1, preventing a large amount of excrement from adhering to the bag 1 and making it difficult to clean, thus improving cleaning efficiency.
