Description

Technical Field

[0001] The present invention relates to the technical field of stoma devices, and in particular to an intestinal stoma device. Background Art

[0002] Currently, ordinary ostomy bags are used for stoma patients, that is, the ostomy bag is adhered to the skin around the incision. This ostomy bag generally consists of two parts, a non-woven gauze (adhering to the skin) bag body (storing intestinal contents). Since the ostomy bag covers the entire incision and stoma during the skin adhesion process, after the intestinal contents come out from the stoma, it is very easy to contaminate the adjacent incision, resulting in incision infection. In mild cases, the wound healing is delayed, and in severe cases, serious infection is caused, inducing subsequent serious problems. Moreover, the ostomy bag is connected to the skin by adhesion, and the skin is easily damaged during the replacement process. Summary of the Invention

[0003] The purpose of the present invention is to provide an intestinal stoma device to solve the problems existing in the above-mentioned prior art, so that the stoma and the incision can be separated to avoid incision infection.

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0027] Embodiment 1

[0028] As Figures 1 to 4 shown: This embodiment provides an intestinal fistula device 1, including a catheter joint, an outlet tube 14 or an ostomy bag 15. One end of the catheter joint is used to pass through the incision of the body surface fistula and is hermetically connected to the incision and the port of the intestinal tube respectively, and the other end is communicated with the outlet tube 14 or the ostomy bag 15.

[0029] The catheter connector includes a catheter 2 and a sealing component. The catheter 2 passes through the sealing component, and the sealing component is hermetically connected to the incision and the port of the intestinal tube respectively. The sealing component includes a silica gel plate 3, an intestinal tube fixing member, and a protective sleeve 4. The silica gel plate 3 is sleeved on the catheter 2. An intestinal tube fixing member and a protective sleeve 4 are arranged on the surface of one side of the silica gel plate 3. The protective sleeve 4 is located outside the intestinal tube fixing member. The intestinal tube fixing member is hermetically connected to the port of the intestinal tube. The protective sleeve 4 is pasted around the incision through a non-woven adhesive tape 5 to cover and protect the entire stoma, ensuring the healing of the incision. The non-woven adhesive tape 5 is preferably an integral structure with the protective sleeve 4. When in use, only the sticker on the non-woven adhesive tape 5 needs to be removed. The catheter 2 connector is an integrally formed part made of medical material. Among them, the silica gel plate 3 is a rigid silica gel plate, which is convenient for providing a setting space for other components; the protective sleeve 4 is a frustum-shaped polyvinyl chloride film, whose shape can be arbitrarily changed and is convenient for the operation of fitting with the incision; the lower end of the catheter 2 is made of soft silica gel, which is convenient for inserting into the stoma colon without damaging the intestinal tube. The upper end of the catheter 2 above the silica gel plate 3 is made of rigid silica gel and is provided with threads, which is convenient for connecting the rigid silica gel screw sleeve on the outlet tube 14 or the ostomy bag 15.

[0030] An intestinal tube locking sleeve 6 is arranged between the intestinal tube fixing member and the protective sleeve 4. One end of the intestinal tube locking sleeve 6 is fixed on the silica gel plate 3, and a contraction band 7 is arranged at the other end. The contraction band 7 is used to lock the port of the intestinal tube on the catheter 2, sealing the end of the intestinal tube again to avoid the leakage of contents and polluting the incision, which is convenient for operation and has strong practicability. Among them, the intestinal tube locking sleeve 6 is made of polyvinyl chloride film, which is convenient for changing the shape for closing and locking; after the colon bag bionic balloon and the intestinal tube are both expanded, the outer wall of the intestinal tube will be fixed by the contraction band 7 at the lower end of the intestinal tube locking sleeve 6. The intestinal tube fixing member is a fixing ring 9 or a protrusion 10. The protrusions 10 are evenly distributed in a circular shape at equal intervals on the surface of the silica gel plate 3. The port of the intestinal tube is sutured with the fixing ring 9 or the protrusion 10 to achieve the sealing connection between the intestinal tube and the catheter 2 and prevent the leakage of intestinal contents.

[0031] At least one colon bag bionic balloon 8 is arranged on the catheter 2. Each colon bag bionic balloon 8 is communicated with an injection tube 12. The injection tube 12 is fixed on the outer wall of the catheter 2. The injection tube 12 is used to inject physiological saline into the colon bag bionic balloon 8, so that the colon bag bionic balloon 8 expands into a colon bag shape to match the inner wall of the colon, and then stably adheres to the inside of the colon. The intestinal tube is separated from the clean incision, preventing the intestinal tube from directly contacting the outside world, effectively controlling the leakage of intestinal contents and excessive loss of liquid in the intestinal tube. A flushing tube 13 is arranged on the outer wall of the catheter 2. The flushing tube 13 extends into the port of the intestinal tube and can inject physiological saline for cleaning the intestinal tube. The outlet tube 14 or the ostomy bag 15 is connected to the catheter 2 by threads. The outlet tube 14 is a telescopic tube and can be stretched when discharging intestinal contents. A discharge valve 16 is arranged at the lower end of the ostomy bag 15 or the middle of the outlet tube 14, which is convenient for controlling the excretion of intestinal contents.

[0032] The specific usage operation of the intestinal fistula device 1 in this embodiment is as follows:

[0033] First, insert the lower end of the catheter 2 into the port of the intestinal tube, suture the port of the intestinal tube to the fixing ring 9, inject an appropriate amount of normal saline into the colon bag bionic balloon 8 through the injection tube 12, expand it into a colon bag shape, and stably attach it in the colon. Then, tighten the end of the intestinal tube with the contraction band 7 of the intestinal tube locking sleeve 6. The protective sleeve 4 adheres to the skin near the incision through non-woven gauze to protect the entire fistula incision and the exposed intestinal tube. Finally, connect the catheter 2 with a thread to the ostomy bag 15 or the outlet tube 14 with a screw sleeve, and inject warm normal saline through the flushing tube 13 to flush and moisten the intestinal tube, and then it can be used normally. After fixing the inserted part of the intestinal tube (the catheter 2 part) in the intestinal tube, select to connect the ostomy bag 15 or the outlet tube 14 according to the patient's needs, and the timely discharge of the contents can be achieved by controlling the discharge valve. In this embodiment, the port of the intestinal tube is sutured to the fixing ring 9, which is suitable for long-term fistulas, and can make the intestinal contents enter the catheter 2 from the intestinal tube without causing external leakage of intestinal contents and contamination of the clean incision.

[0034] Embodiment 2

[0035] As Figure 5 shown, the difference between the structure of this embodiment and that of Embodiment 1 is only that the intestinal tube fixing part is a locking ring 11 or a clamp. The middle part of the locking ring 11 or the clamp is fixedly connected to the silica gel plate 3, and the locking ring 11 or the clamp can lock the port of the intestinal tube onto the catheter 2. In this embodiment, the port of the intestinal tube is locked onto the catheter 2 through the locking ring 11 or the clamp. The intestinal tube fixing part is easy to disassemble, suitable for short-term fistulas, can be stably indwelled within the required time of the condition, and the operation is relatively simple. Other operation steps are the same as those in Embodiment 1.
