Description

Technical Field

[0001] This invention belongs to the field of medical and nursing device technology, and in particular relates to a base structure of an ostomy bag with an ostomy dressing ring. Background Technology

[0002] Stoma surgery is an important treatment for intestinal and bladder diseases. It involves surgically removing one end of the intestine or bladder from the body surface to create a stoma, which is used to drain feces or urine, helping patients maintain normal physiological functions. In stoma care, the ostomy bag is an essential item, while the leak-proof bandage, as an auxiliary care component between the ostomy bag and the skin, is mainly used to fill the folds and gaps in the skin around the stoma, preventing leakage of feces or urine and protecting the skin around the stoma.

[0003] Existing stoma leak-proof rings are mostly simple ring-shaped soft pad structures that only serve to fill gaps and lack a dedicated drainage structure. When feces are discharged from the stoma, feces can easily remain on the inner edge of the leak-proof ring, at the junction of the ring and the skin, or even seep into the gap between the ring and the ostomy bag baseplate, leading to leakage. The leaked feces continuously irritate the skin around the stoma, damaging the skin barrier and causing skin inflammation such as redness, swelling, itching, and erosion, causing great pain to the patient. At the same time, the leaked feces contaminate the ostomy bag baseplate, causing a decrease in the baseplate's adhesiveness and requiring frequent baseplate replacements, increasing the patient's nursing costs and burden.

[0004] To address these issues, we propose a stoma bag base structure with a stoma dressing ring. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an ostomy bag base structure with an ostomy dressing ring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ostomy bag base structure with an ostomy patch ring, comprising an ostomy patch ring body and an ostomy bag snap-fit ​​base, wherein the bottom end of the ostomy bag snap-fit ​​base is fixedly bonded to the upper surface of the ostomy patch ring body, and a plurality of outwardly folded petal-shaped silicone guide plates are fixedly connected to the outer wall of the ostomy patch ring body at the ostomy sleeve hole.

[0007] A sealing mechanism is fixedly connected to the inner wall of the stoma sleeve hole of the stoma patch body. The sealing mechanism includes an annular thin-walled silicone airbag and a plastic limiting pressure ring plate fixedly connected to the inner wall of the stoma sleeve hole of the stoma patch body.

[0008] The lower surface of the stoma dressing ring body is fixedly connected to an adhesive installation mechanism;

[0009] The outer wall of the adhesive installation mechanism has a through hole, and the hole wall is fixedly connected to an inflation mechanism for the sealing mechanism to bulge and seal.

[0010] In the aforementioned ostomy bag chassis structure with stoma dressing ring, the outer wall of the annular thin-walled silicone airbag is fixedly connected to an air inlet pipe. The air inlet end of the air inlet pipe passes through the side wall of the stoma dressing ring body and is fixedly connected to an opening and closing valve. The opening end of the opening and closing valve is fixedly connected to an internal threaded interface.

[0011] In the above-mentioned ostomy bag base structure with ostomy dressing ring, the adhesive installation mechanism includes a reinforcing nonwoven fabric layer that is fixedly bonded to the lower surface of the ostomy dressing ring body. The upper protruding inner wall of the reinforcing nonwoven fabric layer is fixedly connected to the top side wall of the ostomy dressing ring body. The lower surface of the reinforcing nonwoven fabric layer is uniformly coated with an adhesive layer, and an anti-adhesive protective film is pasted on the side of the adhesive layer away from the reinforcing nonwoven fabric layer.

[0012] In the aforementioned ostomy bag base structure with stoma dressing ring, the four corners of the anti-adhesive protective film are integrally formed with easy-tear ear flaps.

[0013] In the above-mentioned ostomy bag base structure with stoma dressing ring, a flow guide gap for fecal flow is reserved between adjacent petal-shaped silicone guide sheets. The surface of the petal-shaped silicone guide sheets is coated with a smooth flow guide layer, and the smooth flow guide layer is made of medical anti-stick material.

[0014] In the above-mentioned ostomy bag base structure with stoma dressing ring, the number of petal-shaped silicone guide sheets is 4-8 pieces, all symmetrically distributed. The thickness of the petal-shaped silicone guide sheets is 0.3-0.8mm, the outward angle is 30°-60°, and the free end of the petal-shaped silicone guide sheets is rounded arc-shaped.

[0015] In the above-mentioned ostomy bag base structure with ostomy patch, the side wall of the ostomy patch body is provided with an annular groove, and the groove wall of the annular groove is fixedly connected with an annular elastic support. The air inlet end of the air inlet pipe passes through the outer wall of the annular elastic support and extends outward. The thickness of the ostomy patch body is 1.0-2.0mm and the outer diameter is 5-10cm.

[0016] In the aforementioned ostomy bag base structure with ostomy patch ring, the inflation mechanism includes an external threaded ring that is threadedly and sealed to the internal threaded interface. A first air inlet check valve is fixedly connected to the inner wall of the external threaded ring. An elastic reset rubber airbag is fixedly sleeved on the outer wall of the external threaded ring. A second air inlet check valve is fixedly connected to the inner wall of the air inlet hole of the elastic reset rubber airbag.

[0017] In the aforementioned ostomy bag base structure with ostomy dressing ring, the lower surface and upper raised outer wall of the reinforcing nonwoven fabric layer are provided with multiple evenly distributed air vents.

[0018] Compared with existing technologies, the advantages of an ostomy bag base structure with an ostomy dressing ring are:

[0019] 1. Through the designed sealing and inflation mechanisms, after the patient completes the attachment and fixation of the stoma dressing ring, the external threaded ring and internal threaded interface of the inflation mechanism are tightened to seal. After opening the opening and closing valve, the elastic reset rubber airbag is repeatedly pressed. With the cooperation of the first and second air intake one-way valves, outside air is pumped into the annular thin-walled silicone airbag. The plastic limiting pressure ring restricts the expansion of the airbag outward, guiding the airbag to expand evenly towards the stoma side, so that the soft thin-walled silicone gently covers the stoma surface, forming an adaptive flexible sealing ring. The sealing force can be flexibly adjusted by the inflation volume. This structure solves the problems of traditional stoma dressing rings that rely solely on filling gaps to achieve passive leak prevention, poor sealing effect, and easy leakage of exudate along the stoma root to the skin and base gaps. It is suitable for stomas of different sizes and shapes, does not cause hard pressure on the stoma, and can block the leakage path of exudate, effectively protecting the skin around the stoma, reducing the probability of skin redness, erosion and other inflammations, and greatly improving the reliability of leak prevention.

[0020] 2. Through the design of petal-shaped silicone guide plates and guide gaps, when feces are discharged from the stoma, the outwardly flared petal-shaped silicone guide plates form a continuous guiding slope, guiding the feces directly into the ostomy bag, avoiding feces residue on the inner edge of the bandage and at the connection between the bandage and the ostomy bag base. The guide gaps reserved between adjacent petal-shaped silicone guide plates can disperse the flow of feces and adapt to the slight deformation of the stoma with body movement, ensuring that the guide process is always smooth. This structure solves the problems of traditional stoma anti-leak bandages lacking a dedicated guide structure, easy feces residue and leakage, continuous contamination of the base adhesive layer leading to decreased base adhesiveness, and frequent replacement. It can effectively extend the service life of the ostomy bag base, reduce the patient's nursing costs and burden, and further reduce the probability of feces contacting the skin, enhancing the skin protection effect.

[0021] 3. Through the designed adhesive installation mechanism and annular elastic support, when the ostomy bag base structure with ostomy patch is used, the reinforced non-woven fabric layer can improve the overall structural strength of the ostomy patch body, preventing deformation of the patch during the pasting and pulling process. Combined with the evenly coated adhesive layer, it achieves a firm fit with the skin. The annular elastic support embedded inside the patch body continuously maintains the ring structure of the patch throughout the patient's daily wear, resisting twisting and deformation caused by limb movement, and ensuring that the sealing structure and drainage structure are always in the correct working position. This structure effectively improves the durability of the device and the comfort of daily use, and extends the effective service life of the patch and base. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-5 As shown, an ostomy bag base structure with an ostomy patch ring includes an ostomy patch ring body 1 and an ostomy bag snap-fit ​​base 2. The bottom end of the ostomy bag snap-fit ​​base 2 is fixedly bonded to the upper surface of the ostomy patch ring body 1. Multiple outwardly folded petal-shaped silicone guide plates 3 are fixedly connected to the outer wall of the ostomy patch ring body 1 at the ostomy sleeve hole.

[0030] The stoma dressing body 1 has a thickness of 2mm and an outer diameter of 10cm. The stoma dressing body 1 is made of breathable, waterproof, and non-irritating medical material, which reduces the probability of inflammation such as skin redness and erosion in patients. The side wall of the stoma dressing body 1 has an annular groove, and the groove wall is fixedly connected to an annular elastic support 9. The annular elastic support 9 is made of medical soft elastic material and is used to maintain the annular structure of the stoma dressing body 1 to prevent the stoma dressing body 1 from deforming and affecting the fitting effect. The air inlet end of the air inlet pipe 43 passes through the outer wall of the annular elastic support 9 and extends outward.

[0031] A flow gap 8 for fecal drainage is reserved between adjacent petal-shaped silicone guide sheets 3. The surface of the petal-shaped silicone guide sheet 3 is coated with a smooth flow layer, and the smooth flow layer is made of medical anti-adhesion material to reduce the adhesion between feces and the petal-shaped silicone guide sheet 3 and ensure smooth discharge of feces. There are 8 petal-shaped silicone guide sheets 3, which are symmetrically distributed. The thickness of the petal-shaped silicone guide sheet 3 is 0.6mm, the outward angle is 45°, and the free end of the petal-shaped silicone guide sheet 3 is rounded arc to avoid scratching the skin or ostomy bag.

[0032] A sealing mechanism 4 is fixedly connected to the inner wall of the stoma sleeve hole of the stoma dressing body 1. The sealing mechanism 4 includes an annular thin-walled silicone airbag 41 and a plastic limiting pressure ring 42 fixedly connected to the inner wall of the stoma sleeve hole of the stoma dressing body 1. The plastic limiting pressure ring 42 is 1 mm thick, which not only has strong structural strength, but also allows for easy trimming of the inner hole size with scissors to adapt to different stoma sizes. An air inlet pipe 43 is fixedly connected to the outer wall of the annular thin-walled silicone airbag 41. The air inlet end of the air inlet pipe 43 passes through the side wall of the stoma dressing body 1 and is fixedly connected to an opening and closing valve 44. The opening end of the opening and closing valve 44 is fixedly connected to an internal thread interface 45. This mechanism can block the leakage path of exudate and reduce the probability of skin redness, swelling, erosion and other inflammations.

[0033] The lower surface of the stoma dressing ring body 1 is fixedly connected to an adhesive installation mechanism 5. The adhesive installation mechanism 5 includes a reinforcing nonwoven fabric layer 51 that is fixedly bonded to the lower surface of the stoma dressing ring body 1. The lower surface and the upper raised outer wall of the reinforcing nonwoven fabric layer 51 are provided with multiple evenly distributed air vents 10. The air vents 10 can improve the air permeability of the reinforcing nonwoven fabric layer 51. The upper raised inner wall of the reinforcing nonwoven fabric layer 51 is fixedly connected to the top side wall of the stoma dressing ring body 1. The lower surface of the reinforcing nonwoven fabric layer 51 is uniformly coated with an adhesive layer 52. An anti-adhesive protective film 53 is pasted on the side of the adhesive layer 52 away from the reinforcing nonwoven fabric layer 51. The four corners of the anti-adhesive protective film 53 are integrally formed with easy-tear ear wings 7.

[0034] The outer wall of the adhesive installation mechanism 5 has a through hole, and the wall of the through hole is fixedly connected to an inflation mechanism 6 for the sealing mechanism 4 to bulge and seal. The inflation mechanism 6 includes an external threaded ring 61 that is threadedly sealed to the internal threaded interface 45. The inner wall of the external threaded ring 61 is fixedly connected to a first air inlet check valve 62. The outer wall of the external threaded ring 61 is fixedly sleeved with an elastic reset rubber airbag 63. The inner wall of the air inlet of the elastic reset rubber airbag 63 is fixedly connected to a second air inlet check valve 64.

[0035] The operating principle of the present invention is described as follows: Before using the stoma bag base structure with stoma dressing ring, the inner hole of the plastic limiting pressure ring 42 is first trimmed according to the actual size of the patient's stoma. This ensures that the diameter of the trimmed inner hole is slightly larger than the outer diameter of the stoma, so that the plastic limiting pressure ring 42 will not obstruct the stoma from passing through the stoma sleeve hole of the stoma dressing ring body 1. It also provides accurate limiting for the expansion direction of the subsequent annular thin-walled silicone airbag 41, and can adapt to stomas of different sizes. It is no longer necessary to strictly select products according to fixed specifications, thus broadening the range of applicable people for the product.

[0036] When using the ostomy bag base structure with stoma ring, the first step is to clean the skin around the stoma and attach the ring, such as... Figure 1 and Figure 2 As shown, first clean the patient's stoma and surrounding skin with warm water, and thoroughly dry them with a soft tissue to ensure that the skin surface is free of sweat and dirt, so as not to affect the adhesion of the adhesive layer 52. Then, pinch the easy-tear ear 7 at the edge of the anti-adhesive protective film 53, and first tear off half of the anti-adhesive protective film 53 to fully expose the stoma sleeve area in the middle of the stoma ring body 1. Align the stoma with the stoma and pass it through the stoma sleeve of the stoma ring body 1. Smoothly apply the exposed adhesive layer 52 to the skin around the stoma, and gently press it with your hand to ensure that it is tightly adhered without any lifting edges. After confirming that the position is correct, tear off the remaining anti-adhesive protective film 53 and press the entire adhesive layer 52 to adhere to the skin to complete the adhesion and fixation of the stoma ring body 1.

[0037] During the application and use, the reinforced nonwoven fabric layer 51 can improve the overall structural strength of the stoma dressing ring body 1 and prevent the dressing ring from deforming when it is stretched. The ventilation holes 10 evenly distributed on the reinforced nonwoven fabric layer 51 can continuously ensure air circulation in the area where the skin contacts the dressing ring, reduce the feeling of stuffiness and dampness on the skin, and reduce the risk of skin redness and inflammation.

[0038] The second step is to assemble the inflation mechanism 6 and complete the sealing of the stoma root, such as... Figures 1-5As shown, align the external threaded ring 61 of the inflation mechanism 6 with the internal threaded interface 45 of the sealing mechanism 4, and rotate and tighten to ensure a seal at the connection. Then open the opening and closing valve 44. The patient gently and repeatedly presses the elastic reset rubber airbag 63 with his hand. With the one-way air guiding action of the first air intake check valve 62 and the second air intake check valve 64, outside air will be continuously pumped in and flow into the annular thin-walled silicone airbag 41 along the air intake pipe 43. As the annular thin-walled silicone airbag 41 gradually expands, the outer plastic limiting pressure ring 42 restricts the airbag from expanding outward, guiding the annular thin-walled silicone airbag 41 to expand evenly towards the stoma side. Since the annular thin-walled silicone airbag 41 is made of soft thin-walled silicone material, it will gently adhere to the stoma surface after expansion. Moreover, the adhesion force can be adjusted by the amount of air injected by the inflation mechanism 6, ensuring that the adhesion force of the annular thin-walled silicone airbag 41 is sufficient to achieve a seal without compressing the stoma, forming a complete flexible sealing structure. After the sealing effect is qualified, the opening and closing valve 44 is closed to maintain the airbag pressure, and then the inflation mechanism 6 is unscrewed.

[0039] The sealing mechanism 4 and the inflation mechanism 6 work together to adaptively adjust the fit according to the actual shape of the stoma, achieving active sealing at the stoma root and effectively preventing exudate from leaking into the gap between the dressing ring and the skin. At the same time, the flexible airbag will not put hard pressure on the stoma, solving the problems of traditional dressing rings that rely solely on filling gaps to prevent leakage, resulting in poor sealing and easy side leakage of exudate, thus greatly improving the reliability of leakage prevention. Moreover, the inflation operation is simple and easy to understand, and patients can complete it independently, making it very convenient to use.

[0040] The third step is to assemble the ostomy bag and facilitate fecal drainage, such as... Figures 1-3 As shown, align the snap ring of the ostomy bag with the snap base plate 2 of the ostomy bag, press evenly to snap it into place, and complete the installation of the ostomy bag; after the ostomy bag is installed, the free end of the petal-shaped silicone guide plate 3 at the inner diameter of the stoma patch 1 will extend into the ostomy bag. When the stoma discharges feces, the arc-shaped outward-curving petal-shaped silicone guide plate 3 will form a continuous guide slope, guiding the feces directly into the ostomy bag and preventing it from remaining at the inner diameter edge of the patch; the pre-reserved guide gap 8 between adjacent petal-shaped silicone guide plates 3 can disperse the flow of feces, while adapting to the slight deformation of the stoma caused by body movement, ensuring that the guide is always smooth; combined with the medical anti-stick smooth guide layer on the surface of the petal-shaped silicone guide plate 3, it can greatly reduce the adhesion between feces and the guide plate, and avoid the growth of bacteria from fecal residue.

[0041] Combined with the previously formed annular thin-walled silicone airbag 41 sealing structure, the device forms a dual leak-proof system at the stoma site, which includes active sealing at the root and outward drainage of waste: the annular thin-walled silicone airbag 41 blocks the leakage of exudate to the skin side from the stoma root, while the petal-shaped silicone drainage plate 3 guides all the discharged feces into the stoma bag. This dual approach effectively solves the core problems of traditional leak-proof rings, such as fecal residue and exudate leakage that irritates the skin. This structure can protect the skin around the stoma, reduce the probability of dermatitis and skin erosion, and reduce the contamination of the stoma bag base plate by feces, effectively extending the service life of the base plate and reducing the nursing cost and burden for patients.

[0042] In addition, during the entire process of daily wear by the patient, the annular elastic support 9 embedded inside the stoma dressing body 1 can continuously maintain the annular structure of the dressing, prevent the dressing from twisting or deforming when the patient moves their limbs, ensure the stability of the adhesive fit, and at the same time allow the petal-shaped silicone guide plate 3 to always maintain the correct outward angle and stably perform the guiding function, further improving the reliability and durability of the device.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
