Description

TECHNICAL FIELD

[0001] The present application relates to a medical ostomy bag, in particular to an ostomy drainage collection bag with a catheter. BACKGROUND

[0002] Intestinal exposure is a serious postoperative complication that may be encountered in digestive tract surgery. The golden rule for the treatment of this complication is early drainage, so as to control infection and improve nutritional status for subsequent treatment. If it still cannot heal by itself through drainage and infusion of nutrient solution, it is determined whether to use surgical treatment. Therefore, sufficient and effective drainage is always the key to treatment. In clinical use, it is often difficult to place and fix the double cannula, and the intestinal fistula liquid stimulates the surrounding tissue.

[0003] To solve the above problems, the prior art will paste an ostomy bag around the stoma for drainage, and the leakage of exudate from the ostomy bag base is relatively common. During the drainage process, when the drainage tube is not fully drained, or the tube is blocked, or there is too much abdominal fluid, or the stoma hole is too large, it will cause a large amount of exudate around the stoma, and also cause infection of the stoma. At the same time, the intestinal fistula liquid stimulates the surrounding skin, causing skin redness, swelling, rash, itching, discomfort, and great inconvenience to the daily life of the patient. After leakage occurs, the ostomy bag needs to be replaced, and the frequent replacement of the ostomy bag caused by leakage of the ostomy bag base will increase the economic burden of the patient.

[0004] In view of the defects of the prior art, some ostomy bags will seal the stoma during use to prevent leakage. By filling the gap between the stoma root and the center hole of the ostomy bag base, the purpose of preventing excrement leakage, protecting the skin around the stoma, and prolonging the service life of the ostomy bag is achieved. The main component of the leakage prevention ring is hydrocolloid, which surrounds the stoma root, and the ostomy bag is pasted on the stoma part where the leakage prevention ring is pasted. The defect of this method is that when the exudate leaks a small amount, the exudate can be absorbed by the leakage prevention ring, thereby preventing the excrement from leaking onto the surrounding skin and irritating the skin. However, if the leakage amount is large, the leakage prevention ring after absorbing the excrement will melt and become soft, thereby losing the leakage prevention effect.

[0005] Through repeated experiments, it is found that the main reason for leakage is still the mismatch between the stoma and the base, which leads to the fact that if the base surrounding the stoma is as large as possible, the drainage will be easier to achieve, and the phenomenon of exudate leakage will be greatly reduced. At the same time, the current ostomy bag or drainage bag does not have a design for catheter insertion, so it is not possible to directly operate the stoma through the ostomy bag. SUMMARY

[0006] The purpose of the present application is to provide an ostomy drainage collection bag with a catheter that can be adjusted according to the shape of the stoma to smoothly drain the drainage part.

[0007] The ostomy drainage collecting bag of the application is realized as follows: an ostomy drainage collecting bag which can be inserted into a catheter comprises a bottom disc connected at a bag opening of the collecting bag, an outer buckle ring with an opening downward is connected at the back of the bottom disc, an elastic leakage prevention layer is arranged on the inner wall of the outer buckle ring, an inner buckle ring with an opening upward is arranged in the outer buckle ring, a drainage plate is connected to the side of the bottom disc, a drainage opening is arranged on the drainage plate, the outer buckle ring, the inner buckle ring and the leakage prevention layer form a closed annular space, the exposed surface of the outer buckle ring, the leakage prevention layer and the inner buckle ring has an adhesive layer, and a first insertion opening for inserting the catheter is arranged at the center of the bottom disc.

[0008] A sleeve is fixed in the first insertion opening, a sealing ring is arranged between the sleeve and the first insertion opening, a plurality of sealing petals are arranged in the inlet and outlet of the sleeve, the plurality of sealing petals form a blocking layer covering the inlet or outlet, and a sealing plug is inserted into the inlet of the sleeve.

[0009] The outer buckle ring is an elastic ring, comprising a fixed part fixedly connected to the back of the bottom disc, and an adjusting part integrally connected to both sides of the fixed part.

[0010] The leakage prevention layer comprises a liquid absorption layer located at the outer ring and an elastic layer located at the inner ring, the liquid absorption layer is fixedly connected to the inner wall of the outer buckle ring, and the liquid absorption layer is fixedly connected to the elastic layer.

[0011] The drainage plate is an elastic arc-shaped plate, the curvature of the drainage plate is the same as the curvature of the inner buckle ring, and the drainage plate is connected to the inner end circumferential surface of the inner buckle ring.

[0012] The length of the drainage plate is at least 2 / 3 of the length of the inner buckle ring.

[0013] The inner buckle ring is an elastic ring, the inner end circumferential surface of the inner buckle ring is designed as an inclined surface with the left side being higher than the right side, the outer end circumferential surface is a plane, a drainage gap is formed at the lowest side of the inner end surface of the inner buckle ring, and the drainage plate is arranged at the drainage gap.

[0014] The drainage plate is an elastic arc-shaped plate, one end of the drainage plate is flush with and connected to the upper edge of the drainage gap, the other end of the drainage plate is inclined downward, and the two sides of the drainage plate are fixedly connected to the inner buckle ring at both sides of the drainage gap, so that the length of the inner buckle ring is the same as the length of the drainage gap.

[0015] By implementing the above technical solutions, the application can quickly drain excrement and exudate into the bag body when the human body exudate is discharged from the stoma, avoid a large amount of excrement from being accumulated on the leakage prevention material with hydrogel components for a long time, thereby improving the leakage prevention effect and reducing the frequency of replacement. The application can also introduce a catheter through the operation opening, so as to perform operations such as intestinal stoma enema, collection of liquid through the stoma (self), flushing of the drainage tube, collection of liquid, and nutrition supply for short bowel syndrome. The application has a simple structure, good leakage prevention effect, and can be applied to various operations at the stoma. BRIEF DESCRIPTION OF DRAWINGS

[0023] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0024] In the description of the application, it should be understood that the terms “center”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0025] Embodiment: As Figures 1-3As shown, the ostomy drainage bag with insertable catheter includes a base 1 connected at the bag opening of a receiving bag 6, an outer buckle 2 connected at the back of the base 1 with the opening downward, an elastic leakproof layer 3 provided on the inner wall of the outer buckle 2, an inner buckle 5 provided in the outer buckle 2 with the opening upward, a drainage plate 5-2 connected to the side of the base 1 on the inner buckle 5, a drainage opening 5-3 provided on the drainage plate 5-2, the outer buckle 2, the inner buckle 5 and the leakproof layer 3 forming a closed annular space, the exposed surfaces of the outer buckle 2, the leakproof layer 3 and the inner buckle 5 having an adhesive layer, and a first insertion opening 8 provided at the center of the base 1 for the insertion of a catheter.

[0026] Further, as shown, Figure 3 the first insertion opening 8 is fixed with a sleeve 4, a sealing ring 9 is provided between the sleeve 4 and the first insertion opening 8, a plurality of sealing flaps 4-1 are provided in the inlet and outlet of the sleeve 4, the plurality of sealing flaps 4-1 form a blocking layer covering the inlet or outlet, and a sealing plug is inserted into the inlet of the sleeve 4.

[0027] Further, as shown, Figure 1 the upper end of the receiving bag 6 is open, and the opening is respectively sealed and connected with the first opening left and right sides of the outer buckle 2, the back of the base 1 and the lower part of the inner buckle 5. The lower end of the receiving bag 6 is provided with a sewage outlet 7, which can be folded upward and held by a clamp to form a blockage.

[0028] Further, the outer buckle 2 is an elastic ring, including a fixed part 2-1 fixedly connected with the back of the base 1, an adjusting part 2-2 integrally connected on both sides of the fixed part 2-1, and an adhesive layer provided on the side of the base 1 of the adjusting part 2-2. When not in use, a lining paper is adhered to the adhesive layer, and the adhesive layer can be a non-drying adhesive.

[0029] Further, the inner buckle 5 is also an elastic ring, which can be forced to shrink during use according to the size of the stoma, and the exposed surface of the inner buckle 5, i.e. the adhesive layer on the side facing the stoma, is bonded to the skin around the stoma. The lower edge of the inner buckle 5 is slightly lower than the lower edge of the stoma, and the rest of the inner buckle 5 surrounds the stoma as close as possible, so that the skin within the range of the inner buckle 5 is as little as possible, reducing the corrosion of the skin by the exudate.

[0030] Further, the leakproof layer 3 includes a liquid absorbing layer on the outer ring and an elastic layer on the inner ring, the liquid absorbing layer is fixedly connected with the inner wall of the outer buckle 2, and the liquid absorbing layer and the elastic layer are fixedly connected, which can be connected by adhesion or heat sealing. The liquid absorbing layer is made of hydrocolloid material, which can effectively absorb exudate. The elastic layer is made of sponge or other materials with deformation and water absorption properties, which can not only absorb exudate, but also fill the gap between the outer buckle 2 and the inner buckle 5 by deformation. Since the liquid absorbing capacity of the elastic layer is small, a liquid absorbing layer is provided outside the elastic layer, so that a large amount of exudate can be absorbed, thereby achieving the effect of blocking leakage.

[0031] In use, the inner buckle ring 5 is first adjusted to be slightly larger than the size of the stoma, then the backing paper attached to the adhesive layer is torn off, and the inner buckle ring 5 is tightly attached to the skin around the stoma. Then the adjustment part 2-2 on both sides of the outer buckle ring 2 is adjusted, and the outer buckle ring 2 is attached to the skin outside the inner buckle ring 5, so that the outer buckle ring 2 is as close to the inner buckle ring 5 as possible, and preferably the two sides of the opening of the outer buckle ring 2 can touch the outer wall of the inner buckle ring 5, that is, the elastic layer in the leakage-proof layer 3 is compressed to the extreme. After the inner buckle ring 5 and the outer buckle ring 2 are attached to the skin outside the stoma, the backing paper on the other side of the outer buckle ring 2 is torn off, and the adjustment part 2-2 is attached to the bottom disc 1, thereby shaping the outer buckle ring 2. The outer buckle ring 2 will block the expansion of the inner buckle ring 5 outward, so as to ensure that the inner buckle ring 5 is always substantially the same size as the stoma. The stoma will be sealed in the closed space formed by the skin, the bottom disc 1, the outer buckle ring 2, the inner buckle ring 5 and the leakage-proof layer 3, and the exudate, feces and the like flowing out of the stoma can be guided to the collection bag 6 through the drainage port 5-3 on the drainage plate 5-2 for collection. If the exudate seeps from the attachment between the inner buckle ring 5 and the skin, it will be absorbed by the leakage-proof layer 3 or flow into the collection bag 6.

[0032] Further, to ensure that the shape of the inner buckle ring 5 matches the stoma, an adhesive layer is also provided on the inner end circumferential surface of the inner buckle ring 5, by which the inner end circumferential surface of the inner buckle ring 5 can be attached to the back of the bottom disc 1, so that the thickness of the inner buckle ring 5 needs to be equal to that of the outer buckle ring 2.

[0033] As shown in Figure 2 , the drainage plate 5-2 is an elastic arc-shaped plate, the curvature of the drainage plate 5-2 is the same as that of the inner buckle ring 5, and the drainage plate 5-2 is connected to the inner end circumferential surface of the inner buckle ring 5. The length of the drainage plate 5 is at least 2 / 3 of the length of the inner buckle ring 5, that is, the drainage plate 5 covers the lower part and both sides of the inner buckle ring 5, so as to ensure that the exudate will be concentrated in the collection bag 6 through the drainage plate 5 when the patient is in a supine or lateral position. If only the standing position of the patient is considered, then the length of the drainage plate 5 can be less than 1 / 2 of the length of the inner buckle ring 5, or even shorter, as shown in the ratio of Figure 2 .

[0034] Since the patient is in a supine position for a long time, in a lateral position for a short time, and in a standing position for a very short time, the present application needs to be optimized as follows.

[0035] As shown in Figure 5 , in order to facilitate rapid drainage when the patient is in a supine position, the inner end circumferential surface of the inner buckle ring 5 is designed as a left-high right-low inclined surface, the outer end circumferential surface is a flat surface, a drainage gap is formed on the lowest side of the inner end surface of the inner buckle ring 5, and the drainage plate 5-2 is arranged at the drainage gap. One end of the drainage plate 5-2 is flush with and connected to the upper edge of the drainage gap, and the other end of the drainage plate 5-2 is inclined downward, that is, inclined toward the skin side. The inner end surface of the inner buckle ring 5 is the surface facing the bottom disc 1, and the outer end surface of the inner buckle ring 5 is the surface attached to the skin.

[0036] Further, the drainage plate 5-2 is an elastic arc-shaped plate, and the two sides of the drainage plate 5-2 are fixedly connected with the inner buckle 5 on both sides of the drainage gap, so that the inner buckle 5 has the same length as the drainage gap, and it is ensured that the liquid seepage will flow out at the drainage plate 5-2.

[0037] Further, as shown in FIG. 6, a second socket 12 is formed on the bag body of the storage bag 6, and the sleeve 4 is inserted into the second socket 12, and the structure and sealing structure of the sleeve 4 are the same as those of the sleeve 4 at the first socket 8. Figure 4

[0038] Further, as shown in FIG. 6, a second socket 12 is formed on the bag body of the storage bag 6, and the sleeve 4 is inserted into the second socket 12, and the structure and sealing structure of the sleeve 4 are the same as those of the sleeve 4 at the first socket 8. Figure 4

[0039] Further, an opening corresponding to the second socket 12 is formed on the lower part of the extension 10, and the front side of the lower part of the extension 10 is sealingly connected with the inner side of the storage bag 6.

[0040] Another catheter can be inserted through the second socket 12, and the catheter is guided to the stoma by the drainage port 5-3. In this way, two catheters can be introduced through the first socket 8 and the second socket 12 at the same time.

[0041] The above technical features constitute the embodiments of the present application, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.​​
