Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical and sanitary appliances, and in particular relates to a leakage-proof ostomy bag. Background Art
[0002] For surgical patients who currently need to have a drainage tube placed to drain the intra-abdominal fluid in clinical practice, such as patients with intestinal fistula, the fistula is small and limited. When a drainage tube is placed at the wound for drainage, the intestinal fluid flows out of the wound where the drainage tube is placed because the drainage tube is not completely in contact with the surrounding skin. At this time, the drainage tube cannot be removed, and the drainage fluid in the abdominal cavity needs to be fully drained, so a stoma bag will be attached to the leakage site. Currently, there is only one outlet at the bottom of the clinical stoma bag, and the opening is large, which cannot fit tightly with the drainage tube. In addition, when there is a drainage tube at the opening, the drainage fluid flowing out of the wound into the stoma bag cannot be better poured out. In order to solve this problem, the existing method is to cut a small hole on the top of the stoma bag, lead the drainage tube out from the small hole, and pour the drainage fluid in the stoma bag out from the original outlet of the stoma bag. However, the sealing of the stoma bag is poor after the hole is cut. When the patient turns over or changes position, the drainage fluid in the stoma bag is easy to flow out from the cut, soiling the patient's clothes and bed sheets, affecting the rest of the patient and his family members, and may also cause discomfort to the patient due to frequent dressing changes, and cause the patient's clothes and bed sheets to be frequently changed and washed, increasing the workload of the patient's family members and nursing staff, and the overall experience is poor.
[0003] Patent CN217645601U discloses a stoma drainage collection device, including a stoma bag, a drainage tube and a drainage bag. The bag body of the stoma bag is provided with an opening, one end of the drainage tube passes through the stoma chassis and enters the stoma, and the other end of the drainage tube passes through the opening and is connected to the drainage bag. A plastic adhesive ring is provided around the opening for sealing. However, this method of sealing with a ring is difficult to adjust arbitrarily according to the size of the drainage tube. Even if the ring is enlarged and lengthened so that it can be cut according to the diameter of the drainage tube, it is still relatively troublesome, and errors are prone to occur during cutting, and leakage may still occur. In addition, the drainage tube is tightly adhered by the ring, and it is still possible to detach from the opening during pulling and friction, resulting in leakage. When the pulling is severe, it may also cause the drainage tube to fall out of the stoma, posing certain safety hazards. Utility Model Content

DETAILED DESCRIPTION
[0018] Embodiment 1
[0019] like Figure 1As shown, this embodiment provides a leak-proof ostomy bag, comprising an ostomy base plate 1, a bag body 2 detachably connected to the ostomy base plate 1, a drainage tube 3 for connecting the ostomy, and a drainage bag 4 connected to the drainage tube 3. The bag body 2 comprises a main body 21 and a bellows-shaped, retractable and foldable extension 23 connected to one side of the main body 21, the drainage tube 3 passes through an opening 231 of the extension 23, a double-sided tape 233 with a surface covered with release paper is adhered around the inner side of the opening 231, and a single-sided tape 235 with a surface covered with release paper is connected to the outer side of the opening 231. When in use, after the drainage tube 3 is passed through the opening 231 of the extension portion 23, the release paper on the surface of the double-sided tape 233 of the opening 231 is torn off, and the double-sided tape 233 is pinched according to the diameter of the drainage tube 3 so that the double-sided tape 233 wraps the drainage tube 3 and seals the opening 231. Then the release paper on the surface of the single-sided tape 235 is torn off, and the single-sided tape 235 is used to wrap the interface between the opening 231 and the drainage tube 3 tightly and wrap it around and stick it for several turns to further tighten the sealing structure at the interface between the opening 231 and the drainage tube 3 to prevent liquid flowing out of the stoma wound from leaking from the interface. The retractable and foldable extension portion 23 is used to prevent the drainage tube 3 from directly falling out of the stoma when it is accidentally pulled. When the drainage tube 3 is led out from the extension portion 23, the extension portion 23 is folded. Based on the retractable and foldable length range of the extension portion 23, a tube segment of corresponding length is reserved for the drainage tube 3 in the bag body 2. In this way, even if the patient's drainage tube 3 or drainage bag 4 is accidentally pulled, the extension portion 23 in the folded state is stretched by external force. The extension portion 23 in the folded state can play a buffering role, avoiding direct pulling on the drainage tube 3 and pulling the drainage tube 3 off the stoma, which has higher safety.
[0020] In this embodiment, the lining of the bag body 2 is made of non-woven fabric, which has higher comfort level. A flow guide port 27 is provided at the bottom of the main body 21, and the flow guide port 27 is sealed by a double-layer PP sealing strip 271. Belts 5 for fixing are respectively connected to both sides of the stoma chassis 1, and the two belts 5 are connected by Velcro 51. Considering the different waist circumferences of different patients, the fur surface of the Velcro 51 is designed to be longer, so that the hook surface of the Velcro 51 can be bonded to the corresponding fur surface position according to the specific waist circumference of the patient, so that the belt 5 has the advantage of arbitrarily adjustable connection length. The surface of the stoma chassis 1 is provided with circular scale lines for matching the size of the stoma. The outlet of the drainage tube 3 is connected to the upper part of the drainage bag 4, and the upper part of the drainage bag 4 is provided with a single-sided adhesive strip 41 for sealing with a surface covered with release paper at the connection point. The connection between the drainage tube 3 and the upper part of the drainage bag 4 is wrapped and bonded by the single-sided adhesive strip 41 to strengthen the connection between the drainage tube 3 and the upper part of the drainage bag 4, thereby preventing leakage at the connection or the drainage tube 3 from falling out of the upper part of the drainage bag 4.
[0021] The anti-leakage ostomy bag of the present embodiment is provided with a retractable and foldable extension part for the drainage tube to pass through on the bag body detachably connected to the stoma base plate. A double-sided tape with a surface covered with release paper is adhered around the inner side surface of the opening of the extension part, and a single-sided tape with a surface covered with release paper is connected to the outer side surface of the opening. When in use, it is only necessary to pinch the double-sided tape on the inner side of the opening according to the diameter of the drainage tube, so that the double-sided tape wraps and sticks the drainage tube tightly, and then use the single-sided tape to reinforce the seal. The double-sided tape on the inner side of the opening can be adjusted and tightened at will according to the diameter of the drainage tube, and can be suitable for drainage tubes of different diameters, which is convenient for medical staff to operate quickly, and has a good sealing effect, which can effectively solve the problem of leakage of the ostomy bag; and the retractable and foldable extension part can prevent the drainage tube from directly falling out of the stoma when it is accidentally pulled, and has a buffering effect on the accidental pulling of the drainage tube or the drainage bag, so as to avoid the drainage tube being directly pulled out of the stoma, and has higher safety.
[0022] Embodiment 2
[0023] like Figure 2 As shown, compared with the first embodiment, the difference of the leakage-proof ostomy bag of this embodiment is that the main body 21 includes a buffer bag 211 detachably connected to the stoma base 1, a connecting tube 213 with one end connected to the bottom of the buffer bag 211, and a discharge bag 215 connected to the other end of the connecting tube 213, and a sheet-shaped tube clamp 217 is clamped on the connecting tube 213. The buffer bag 211 is detachably connected to the stoma base 1. If the main body 21 only has the buffer bag 211, and the connecting tube 213 and the discharge bag 215 are not provided, the buffer bag 211 needs to be directly operated every time the liquid overflowing from the stoma is discharged. The buffer bag 211 is very close to the stoma. In order to avoid affecting the stoma or accidentally pulling off the buffer bag 211, more care must be taken, and the operation is inconvenient. In this embodiment, the main body 21 is designed to be a buffer bag 211, a connecting tube 213 and a discharge bag 215 which are connected in sequence. The liquid in the buffer bag 211 is drained to the discharge bag 215 through the connecting tube 213. In this way, each time the liquid overflowing from the stoma is discharged, only the discharge bag 215 needs to be operated, and the risk of affecting the stoma or accidentally pulling off the buffer bag 211 is small, and the operation is more convenient. The remaining beneficial effects of this embodiment are the same as those of the first embodiment, and will not be repeated here.
