Description

Technical Field

[0001] The utility model relates to the technical field of ostomy bags, in particular to an ostomy bag with an adjustable hole size. Background Art

[0002] Stoma bags are used as containers for storing any excreta, such as urine and feces, and are suitable for people with anorectal, urethral, ​​and double-cavity stomas. When using a stoma bag, it is usually necessary to cut the opening according to one's own situation, tear off the protective film on the rubber ring of the stoma bag, and stick the stoma bag flatly on the skin around the stoma to collect excreta. For example, a stoma bag with a publication number of "CN214908958U" has a skin-friendly layer on one surface of the stoma bag body to improve the comfort of the patient, and the support layer is fixed between the skin-friendly layer and the stoma bag body through various connections and cooperation to prevent the patient from folding and twisting the stoma bag body during free activities and causing wound infection. When the stoma bag is used up, the support layer is untied and taken out through the gap between the skin-friendly layer and the stoma bag body. It can be reused and is easy to operate, but the stoma bag still has the following disadvantages in actual use:

[0003] When the above mechanism is in use, a hole is cut on the ostomy bag body with scissors, and then the drainage tube is passed through. However, the size of the hole is difficult to control, resulting in the inability to use drainage tubes of various thicknesses. At the same time, the sealing performance is poor, and when the patient lies down and the ostomy bag is placed horizontally, the excrement inside it will flow back, causing secondary infection to the patient.

[0004] Therefore, we proposed an ostomy bag with adjustable hole size to solve the above problems well. Utility Model Content

[0031] The invention also includes: a fixing ring 6 is bonded to the front of the ostomy bag body 1 at the position of the connecting port 3, and a cover plate 4 is hingedly connected to the front of the ostomy bag body 1 above the fixing ring 6, the cover plate 4 corresponds to the position of the fixing ring 6, and the cover plate 4 and the fixing ring 6 are snap-fitted; an adjusting structure is arranged inside the fixing ring 6, and drainage tubes of different thicknesses can be fixed by expanding and contracting the air bag 8, so as to facilitate the use of drainage tubes of various thicknesses, and at the same time ensure sealing, the adjusting structure includes an air bag 8 bonded to the inner side of the fixing ring 6, and an air inlet pipe 9 is fixed to the bottom of the air bag 8, and a valve is installed inside the air inlet pipe 9;

[0032] When in use, the medical staff opens the cover 4, and then passes the drainage tube through the connecting port 3. The medical staff then connects the air pump to the air inlet pipe 9 and starts the air pump, so that the air pump inflates or deflates the airbag 8 through the air inlet pipe 9, thereby causing the airbag 8 to expand or contract, so that it fits tightly with the outside of the drainage tube, thereby being able to adjust the size of the connecting port 3 and fix drainage tubes of different thicknesses, thereby facilitating the use of drainage tubes of various thicknesses, while also ensuring sealing. Furthermore, the valve provided can prevent gas turbulence.

[0033] Embodiment 2: Different from Embodiment 1, in this embodiment, the Velcro fur surface 12 is bonded to the Velcro hook surface 11, so that the skin-friendly layer 13 can be fixed to the back of the ostomy bag body 1, thereby improving the patient's comfort. For details, refer to Figure 2As shown, the back of the ostomy bag body 1 is sutured and connected with a Velcro hook surface 11, a skin-friendly layer 13 is provided on the right side of the ostomy bag body 1, and a Velcro fleece surface 12 is sewed on the left side of the skin-friendly layer 13, and the Velcro fleece surface 12 and the Velcro hook surface 11 are bonded and connected to each other;

[0034] The Velcro fleece surface 12 on the skin-friendly layer 13 is adhered to the Velcro hook surface 11 on the ostomy bag body 1 to complete the fixation of the skin-friendly layer 13, and then the ostomy bag body 1 is fixed to the patient's body through the connecting belt 5. The provided skin-friendly layer 13 can improve the patient's comfort. Then, after the use of the ostomy bag body 1 is completed, the medical staff removes and replaces the skin-friendly layer 13, thereby preventing cross infection and improving safety.

[0035] Embodiment 3: Different from Embodiment 2, this embodiment utilizes the elastic force of the reset spring 7 to drive the movable block 15 to reset upward, and can block the feed port 16, thereby preventing the excrement in the ostomy bag body 1 from flowing back. For details, refer to Figure 2 , Figure 4 and Figure 5 As shown, an anti-backflow structure is provided inside the ostomy bag body 1, and the elastic force of the reset spring 7 is used to drive the movable block 15 to move upward and reset, and the feed port 16 is blocked, so as to prevent the excrement in the ostomy bag body 1 from backflowing. The anti-backflow structure is provided on the baffle 14 inside the ostomy bag body 1, and the feed port 16 is provided inside the baffle 14. A fixing rod 10 is bonded to the top of the inner wall of the ostomy bag body 1, and the fixing rod 10 is provided in a "T" shape. The two ends of the reset spring 7 are respectively fixedly connected to the bottom of the movable block 15 and the outer side of the lower end of the fixing rod 10, the baffle 14 is provided in a funnel shape, and the outer side of the lower end of the fixing rod 10 is sleeved with the movable block 15, and the fixing rod 10 is located on the outer side of the lower end of the movable block 15 and is wound with the reset spring 7, the movable block 15 and the fixed rod 10 are slidably connected, and the outer side of the movable block 15 is in contact with the inner wall of the feed port 16, and the upper end of the movable block 15 is provided in an arc shape;

[0036] When excrement enters the ostomy bag body 1, it will fall on the baffle 14, and because the baffle 14 is arranged in a funnel shape, the excrement will be concentrated on the movable block 15. At this time, the movable block 15 will be weighed down and move downward on the fixed rod 10 (the gravity of the excrement must be greater than the elastic force of the reset spring 7), so that the movable block 15 no longer blocks the feed port 16. At this time, the excrement will enter the lower part of the ostomy bag body 1 from the feed port 16, and then when the addition of excrement stops, the movable block 15 will reset under the elastic force of the reset spring 7 and block the feed port 16, thereby preventing the excrement in the ostomy bag body 1 from flowing back when the patient lies down.
