[0034] An ostomy bag is a type of container used to store human excreta such as urine and feces. The ostomy bag is mainly composed of a base and a bag. The bag is used to hold excreta flowing out of the stoma. After a certain period of use, the bag needs to be cleaned. At present, the connection between the base and the bag of the ostomy bag is achieved by direct hard pressing, which will affect the stoma and cause discomfort when wearing.

[0035] In view of this, the utility model proposes an ostomy bag. When the chassis and the ostomy bag structure are installed, the limiting part arranged on the annular protrusion corresponds to the corresponding screw-on groove. The ostomy bag structure is rotated under the action of an external force, so that the fixing ring rotates relative to the annular connector, and then the limiting part slides along the screw-on groove. After the limiting part slides into place, the annular connector and the fixing ring can be locked to achieve a sealed connection between the chassis and the ostomy bag. During the installation process of the chassis and the ostomy bag structure, there is no pressing operation, so the stoma will not be squeezed, making it more comfortable to wear. Figures 1 to 6 FIG. 1 is an embodiment of the ostomy bag provided by the utility model.

[0036] like Figures 1 to 4 As shown, the ostomy bag 100 proposed by the utility model includes a base plate 1, an annular connector 2 and an ostomy bag structure 3, the base plate 1 is provided with a pre-cut hole 11, the lower end surface of the base plate 1 is provided with an adhesive sheet, so as to fix the base plate 1 at the stoma; the annular connector 2 is provided on the upper end surface of the base plate 1 and covers the pre-cut hole 11, the upper end surface of the annular connector 2 is formed with an annular convex portion 21, and the outer wall surface of the annular convex portion 21 is provided with a limiting portion 211; the ostomy bag structure 3 includes a fixing ring 31 and a bag body 32 provided on the upper end surface of the fixing ring 31, the inner wall surface of the fixing ring 31 is correspondingly provided with a screw-on groove 311, so as to allow the limiting portion 211 to pass through and slide and install.

[0037] In the technical solution of the utility model, the ostomy bag 100 includes a base plate 1, an annular connector 2 and an ostomy bag structure 3. The base plate 1 is provided with a pre-cut hole 11. The lower end surface of the base plate 1 is provided with an adhesive sheet to fix the base plate 1 at the stoma. The annular connector 2 is provided on the upper end surface of the base plate 1 and covers the pre-cut hole 11. The upper end surface of the annular connector 2 is formed with an annular convex portion 21. The outer wall surface of the annular convex portion 21 is provided with a limiting portion 211. The ostomy bag structure 3 includes a fixing ring 31 and a bag body 32 provided on the upper end surface of the fixing ring 31. The inner wall surface of the fixing ring 31 is provided with a screw-on groove 311 for the limiting portion 211 to penetrate and slide. The pre-cut hole 11 is reserved on the base plate 1 for the scissors to penetrate, so as to facilitate cutting a hole suitable for the size of the patient's stoma on the base plate 1. Among them, when the chassis 1 and the ostomy bag structure 3 are installed, the limiting portion 211 arranged on the annular protrusion 21 corresponds to the corresponding screw-on groove 311, and the ostomy bag structure 3 is rotated under the action of external force, so that the fixing ring 31 rotates relative to the annular connector 2, and then the limiting portion 211 slides along the screw-on groove 311. After the limiting portion 211 slides into place, the annular connector 2 and the fixing ring 31 can be locked to achieve a sealed connection between the chassis 1 and the ostomy bag 100. During the installation process of the chassis 1 and the ostomy bag structure 3, there is no pressing operation, so the stoma will not be squeezed, making it more comfortable to wear.

[0038] Specifically, in this embodiment, Figure 3 and Figure 4 As shown, the screwing groove 311 includes a guide groove section 311a and a hanging groove section 311b. The guide groove section 311a extends in the up-down direction and passes through the lower end surface of the fixing ring 31 downward, so as to allow the limiting portion 211 to pass through and slide. One end of the hanging groove section 311b is connected to one side of the guide groove section 311a and is arranged at an angle with the guide groove section 311a, so as to allow the limiting portion 211 to be hung. When the annular connector 2 is connected to the ostomy bag structure 3, the limiting portion 211 on the annular connector 2 is passed through the guide groove section 311a, and the fixing ring 31 is screwed so that the limiting portion 211 slides along the guide groove section 311a until it enters the hanging groove section 311b, so that the fixing ring 31 is locked with the annular connector 2.

[0039] In this embodiment, if Figure 1 As shown, the pre-cut hole 11 is located on one side of the center of the chassis 1 .

[0040] By offsetting the pre-cut hole 11 to one side of the center of the base plate 1, the ostomy bag 100 can be used by patients with double-cavity stomas or loop stomas, thereby improving the versatility of the stoma bag 100. For normal stoma patients, the adhesive surface of the pre-cut hole 11 close to the center of the base plate 1 is larger, so that the base plate 1 and the surrounding skin of the stoma are more firmly adhered.

[0041] In this embodiment, if Figure 1 As shown, a release film 12 is provided on the side of the adhesive sheet facing away from the base plate 1, and a plurality of cutting coils 121 are provided on the release film 12 and are located outside the pre-cut hole 11. The areas of the cutting coils 121 are different to correspond to stomas of different sizes. In this way, appropriate holes can be cut on the base plate 1 along the corresponding cutting lines according to the size of the patient's stoma, so that the base plate 1 can be adapted to the stoma.

[0042] The bag body 32 is used to hold excrement flowing out of the stoma. Since there is gas in the excrement, in order to avoid the problem of bag bulging after long-term use, it is generally necessary to exhaust the gas. Specifically, in this embodiment, Figure 6 As shown, an exhaust port is provided on the upper side of the bag body 32, and a waterproof breathable membrane 321 is provided at the exhaust port. The waterproof breathable membrane 321 has a waterproof and breathable function, so that the gas in the bag body 32 can be discharged in time to prevent the bag from bulging.

[0043] Specifically, in this embodiment, Figure 6 As shown, a drain valve 322 is provided at the bottom of the bag body 32 to connect the cavity of the bag body 32 with the outside. In this way, after the ostomy bag 100 has been used for a period of time, the excrement in the bag body 32 can be discharged by opening the drain valve 322, which is convenient and simple to operate.

[0044] During use, when the excrement in the bag body 32 is almost full, backflow is likely to occur, which may affect the health of the patient. An anti-backflow structure is provided in the bag body 32. Specifically, in this embodiment, Figure 5As shown, the bag body 32 is provided with two waterproof membranes 323 stacked in the vertical direction. The two waterproof membranes 323 are welded and fixed to define a drainage channel together. One end of the drainage channel is connected to the opening of the bag body 32, and the other end is connected to the cavity of the bag body 32. After the excreta of the stoma flows into the cavity of the bag body 32 from the opening of the bag body 32 through the drainage channel, liquid remains on the two waterproof membranes 323. Since the thickness of the waterproof membrane 323 is small, the two waterproof membranes 323 can be adsorbed and attached to close the drainage channel. Therefore, the excreta in the cavity of the bag body 32 cannot flow back to the opening of the bag body 32, avoiding stoma infection and ensuring the health of the patient. It should be noted that the waterproof membrane 323 is a film made of polyolefin or polyester material.

[0045] In this embodiment, the cross section of the drainage channel is reduced from the opening of the bag body 32 to the bottom of the bag body 32. In this way, the drainage channel and the cavity of the bag body 32 have a smaller communication port, so that the closure effect of the drainage channel is better, so as to improve the anti-backflow effect.

[0046] In one embodiment, the outer wall surface of the annular connector 2 is provided with a first connecting portion 22, and the first connecting portion 22 is provided with a first penetration hole 221 for the belt buckle to penetrate; after the base plate 1 is adhered to the stoma of the patient, the belt buckle on the belt passes through the first penetration hole 221 to fix the base plate 1 again through the belt, thereby improving the reliability of the installation of the ostomy bag 100. In another example, the outer wall surface of the fixing ring 31 is provided with a second connecting portion 312, and the second connecting portion 312 is provided with a second penetration hole 312a for the belt buckle to penetrate; the belt buckle on the belt passes through the second penetration hole 312a to tie the ostomy bag structure 3 to the body through the belt, thereby helping to improve the reliability of the connection between the annular connector 2 and the ostomy bag structure 3. In another embodiment, the outer wall of the annular connector 2 is provided with a first connecting portion 22, and the first connecting portion 22 is provided with a first penetration hole 221 for the belt buckle to penetrate; the outer wall of the fixing ring 31 is provided with a second connecting portion 312, and the second connecting portion 312 is provided with a second penetration hole 312a for the belt buckle to penetrate. Specifically, in this embodiment, Figures 1 to 3As shown, the outer wall surface of the annular connector 2 is provided with a first connection portion 22, and the first connection portion 22 is provided with a first penetration hole 221 for the belt buckle to penetrate; the outer wall surface of the fixing ring 31 is provided with a second connection portion 312, and the second connection portion 312 is provided with a second penetration hole 312a for the belt buckle to penetrate. After the base plate 1 is attached to the stoma of the patient, the belt buckle on the belt is passed through the first penetration hole 221 to fix the base plate 1 again through the belt, and the belt is used again, and the belt buckle on the belt is passed through the second penetration hole 312a to tie the ostomy bag structure 3 to the body through the belt, so as to improve the stability of the ostomy bag 100.

[0047] Optionally, the chassis 1 is fixedly welded to the annular connector 2. By welding, the chassis 1 and the annular connector 2 are integrated, and the ostomy bag structure 3 only needs to be connected to the annular connector 2 to complete the assembly of the ostomy bag 100, so that the assembly of the ostomy bag 100 is simple and convenient, and the chassis 1 and the annular connector 2 are welded and fixed with good sealing performance.

[0048] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
