Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides an enterostomy occluder, including an occluder structure, a gas storage cylinder 9, and an occluder plug 12. The occluder structure includes a pressure cap 1, with adhesive tape 4 on both sides of the pressure cap 1. The bottom of the adhesive tape 4 is coated with adhesive 5. With the adhesive 5, the pressure cap 1 can be fixed to the patient's skin by the adhesive tape 4 during use. The bottom of the adhesive 5 is covered with a release paper 6, and the end of the release paper 6 near the pressure cap 1 is bent downwards, making it easy for the user to tear off the release paper 6.

[0025] A sealing airbag 2 is fixedly connected to the bottom of the pressure cap 1. The bottom of the sealing airbag 2 has a groove in the middle, which can cover the patient's exposed ostomy mask. A shaping ring 3 is fixedly connected to the bottom of the sealing airbag 2. The inner diameter of the shaping ring 3 is the same as the inner diameter of the groove. The shaping ring 3 makes it easy for the user to move the sealing airbag 2 so that the sealing airbag 2 covers the patient's ostomy mask.

[0026] As described above, when using this occluder, the user can cover the exposed stoma with the external sealing structure formed by the sealing airbag 2, the shaping ring 3, and the pressure cap 1. When the user presses the pressure cap 1, the sealing airbag 2 can deform and fit tightly against the stoma, thus achieving external sealing of the stoma. After the stoma is externally sealed, the user can use the adhesive tape 4 to fix the position of the external sealing structure.

[0027] The outer surface of the shaping ring 3 is wrapped with a flexible pad, which can be made of silicone, to improve the comfort of using the external sealing structure.

[0028] An inflation tube 7 is fixedly connected to the middle of the pressure cap 1. The inner diameter of the inflation tube 7 is smaller than the inner diameter of the enterostomy port. The size of the inflation tube 7 can be set according to the requirements and is not limited here. The top of the inflation tube 7 is flush with the top of the pressure cap 1. The bottom of the inflation tube 7 is located below the shaping ring 3. An inflation airbag 8 is fixedly connected to the bottom of the inflation tube 7. An inflation port that matches the sealing plug 12 is provided in the middle of the top of the inflation tube 7. The inflation port can be blocked by the sealing plug 12 to improve the sealing performance of the inflation tube 7.

[0029] A support mesh plate 2 17 is fixedly connected to the top of the inner cavity of the inflation tube 7. A magnet plate 2 19 is connected to the top of the support mesh plate 2 17 via a spring 2 18. The magnet plate 2 19 is adapted to the inflation port, with the inner diameter of the inflation port, the outer diameter of the magnet plate 2 19, and the inner diameter of the inflation tube 7 increasing sequentially. A flexible pad, which can be made of rubber, is wrapped around the outer surface of the magnet plate 2 19. Due to the spring 2 18's rebound force, the magnet plate 2 19 and the top of the inner cavity of the inflation tube 7 are in a tight fit, effectively sealing the inflation port. A magnetic block 16, which can be made of iron, is fixedly connected to the top of the inner cavity of the inflation tube 7. The magnetic block 16 and the magnet plate 2 19 are magnetically attracted to each other, improving the effectiveness of the magnet plate 2 19.

[0030] The gas cylinder 9 stores air to inflate the airbag 8, and the air in the gas cylinder 9 allows the airbag 8 to fit tightly against the inner wall of the enterostomy opening. A piston 11 is movably connected inside the gas cylinder 9, and a push rod 10 is fixedly connected to the top of the piston 11. The other end of the push rod 10 extends to the outside of the gas cylinder 9 and is movably connected to the gas cylinder 9. The user can use the push rod 10 to move the piston 11, which can compress the gas stored in the gas cylinder 9. The bottom of the gas cylinder 9... The system includes an exhaust pipe adapted to the inflation port in the middle, with an exhaust hole at the bottom center of the exhaust pipe. A support mesh plate 13 is fixedly connected to the top of the exhaust pipe's inner cavity. A magnetic plate 15, adapted to the exhaust hole, is connected to the bottom of the support mesh plate 13 via a spring 14. The inner diameter of the exhaust pipe, the outer diameter of the magnetic plate 15, and the inner diameter of the exhaust hole decrease sequentially. A flexible pad covers the outer surface of the magnetic plate 15, and a magnetic block 16 is fixedly connected to the bottom of the exhaust pipe's inner cavity. The magnetic block 16 and the magnetic plate 15 are magnetically attracted to each other. The spring 14 applies a downward pushing force to the magnetic plate 15. Under the action of this pushing force and the magnetic attraction between the magnetic block 16 and the magnetic plate 15, the magnetic plate 15 can tightly fit against the top of the exhaust hole, sealing the exhaust hole and preventing gas from escaping from the gas storage cylinder 9.

[0031] The aforementioned magnetic plate 15 and magnetic plate 19 are in a state of magnetic repulsion. Both magnetic plates 15 and 19 are made of permanent magnets. When the bottom of the exhaust pipe overlaps with the top of the inflation pipe 7, the magnetic repulsion between magnetic plates 15 and 19 can cancel out the thrust on magnetic plate 15 and magnetic plate 19. As the exhaust pipe continues to be inserted, magnetic plate 15 can be separated from the exhaust port, and magnetic plate 19 can be separated from the inflation port. The piston 11 can squeeze the gas in the gas storage bottle 9 into the inflation bladder 8, which can seal the inner cavity of the enterostomy. The inflation pipe 7 and the inflation bladder 8 form an internal sealing structure.

[0032] As described above, the enterostomy can achieve both external and internal sealing, improving its sealing performance. Furthermore, this occluder eliminates the need for additional inflation tools, enhancing ease of use. The expansion size of the inflation bladder 8 can be accurately controlled, reducing the difficulty of use. Additionally, the occluder allows for the selection of a suitable gas cylinder 9 based on the size of the enterostomy, making it adaptable to various needs.

[0033] The pressure cap 1, sealing airbag 2, and gas storage bottle 9 in this sealing device are all made of transparent material. The material can be selected according to the requirements and there are no restrictions here.

[0034] In summary: When using this enterostomy occluder, the user places the outer sealing structure over the patient's exposed enterostomy. At this time, the enterostomy is located inside the groove, the shaping ring 3 is in contact with the patient's skin, and the inflation tube 7 and the inflation balloon 8 are inserted into the patient's enterostomy. The user presses the pressure cap 1, which compresses the sealing balloon 2. The sealing balloon 2 deforms under pressure until it fits tightly against the top and outer wall of the enterostomy. The outer sealing structure achieves an external seal on the patient's enterostomy. The user presses the pressure cap 1 with one hand and tears off the release paper 6 with the other hand, using the adhesive tape 4 to fix the outer sealing structure to the patient's skin.

[0035] The user inserts the exhaust pipe of the gas cylinder 9 into the inner cavity of the inflation port. During the insertion of the exhaust pipe, the magnetic repulsion between the first magnetic plate 15 and the second magnetic plate 19 gradually increases. Under the action of the magnetic repulsion, the first magnetic plate 15 can be separated from the exhaust port, and the second magnetic plate 19 can be separated from the inflation port. The user squeezes the push rod 10, which drives the piston 11 to move. The piston 11 can squeeze the gas in the gas cylinder 9 into the inner cavity of the inflation bag 8, realizing the quantitative inflation of the inflation bag 8. The inflation bag 8 achieves the internal sealing of the enterostomy port. The user pulls out the gas cylinder 9 and uses the sealing plug 12 to seal the inflation port, further improving the sealing performance of the sealing device.

[0036] When removing the occluder, the user first inserts the exhaust pipe of the gas cylinder 9 into the inner cavity of the inflation port. The user then pulls the push rod 10 outward, and the rebound force of the inflation bladder 8 causes the gas inside to enter the gas cylinder 9, thereby deflating the inflation bladder 8 and releasing the inner seal of the enterostomy. The user then tears off the adhesive tape 4, and under the action of the rebound force of the sealing bladder 2, the sealing bladder 2 releases the outer seal of the enterostomy, and the occluder can be removed.
