Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially is involved in a fistula nursing device. BACKGROUND

[0002] Intestinal fistula is a common serious complication after abdominal operation, and is common in intestinal advanced tumor and radiation enteritis, and its clinical treatment has higher difficulty. For intestinal fistula patients, realizing fistula sufficient drainage, infection control and nutrition support is the key measure for shortening the course and reducing complications.

[0003] The prior art is to combine the stoma drainage bag and the continuous negative pressure suction, and the overflowed intestinal contents are timely sucked away through the negative pressure suction, so that the fistula and the surrounding tissue are kept clean. However, in actual clinical operation, the intestinal contents cannot be well sucked away, but leak to the periphery of the stoma bag and accumulate between the stoma bag bottom plate and the skin tissue, which continuously corrodes the tissue around the fistula. The reasons are as follows: (1) the conventional stoma bag is made of polyethylene plastic material, and when the continuous negative pressure suction is performed, the plastic material will adhere to the suction pipe opening, block the opening and close the drainage channel; (2) when the negative pressure is formed in the stoma bag, the stoma bag will adhere to the surface of the fistula, preventing the intestinal contents from being discharged from the intestinal fistula; (3) in order to protect the fistula from being damaged by the negative pressure suction or mechanical damage, the negative pressure drainage pipe opening is not directly opposite to the fistula, and similarly, when the negative pressure is formed in the bag, the plastic surface of the stoma bag will adhere to the stoma bag bottom plate due to the negative pressure, also closing the drainage channel. Therefore, when the intestinal contents overflow under the action of intestinal pressure, they first accumulate at the fistula, and then spread to the periphery under pressure, and when a large amount of intestinal contents accumulates between the negative pressure drainage pipe opening and the intestinal fistula, the negative pressure suction can form effective suction, and the intestinal overflow can be drained. This method is not conducive to the overflow of intestinal contents on the one hand, and on the other hand, due to the poor negative pressure drainage effect, it is easy to form overflow of intestinal contents under the stoma bag bottom plate (between the stoma bag bottom plate and the skin soft tissue) or even outside the stoma bag bottom plate. The clinical solution is to frequently replace the stoma bag, which often needs to be replaced 2-3 times a day. The fistula nursing is time-consuming and laborious, and the effect is still not good.

[0036] like Figure 1 and Figure 2 As shown, the fistula care device provided by this utility model includes: an ostomy bag body 1 and an inner lining support cover 5.

[0037] The inner lining support cover 5 is located inside the ostomy bag body 1.

[0038] The ostomy bag body 1 is made of the same material as the ostomy bag body 1 in the prior art; the inner lining support cover 5 has a certain support force and is not easily deformed, and its material can be transparent PET plastic.

[0039] The ostomy bag body 1 is provided with an ostomy bag base plate 2 and an ostomy bag discharge port 3.

[0040] The ostomy bag base plate 2 is cut to size, allowing users to cut the appropriate holes according to the size of the patient's fistula.

[0041] The ostomy bag's drainage port 3 is sealed and connected to the inner lining suction tube 4, which passes through the inner lining support cover 5. The outer port of the inner lining suction tube 4 is connected to negative pressure to suction intestinal contents.

[0042] The opening of the inner lining support cover 5 faces the ostomy bag base plate 2 and covers the ostomy bag base plate 2. The inner lining support cover 5 includes a first cover body 9 and a second cover body 10, with the openings of the first cover body 9 and the second cover body 10 facing the same direction. The first cover body 9 covers the ostomy bag base plate 2 and provides support. The second cover body 10 is connected below the first cover body 9 and forms a storage volume. After intestinal contents leak out, the flushing fluid is first drained into the storage volume and then suctioned out by the inner lining suction tube 4.

[0043] The first cover 9 and the second cover 10 are connected by a connecting channel. Along the direction from the first cover 9 to the second cover 10, the cross-sectional area of ​​the connecting channel first decreases and then increases, thereby forming a narrow channel between the first cover 9 and the second cover 10. This makes it difficult for intestinal contents that have entered the second cover 10 to flow back to the first cover 9 side.

[0044] The fistula care device also includes an inlet tube 6 and an air inlet tube 7, both of which penetrate the ostomy bag body 1 and the inner lining support cover 5. Both the inlet tube 6 and the air inlet tube 7 are located on one side of the first cover 9, and in this embodiment, there are two of each.

[0045] Both the first cover 9 and the second cover 10 protrude toward the side opposite to the ostomy bag base plate 2, so that they can still be formed into their original shape under negative pressure and are not easily deformed.

[0046] A plug 8 is connected to the intake pipe 7. The plug 8 is connected to the intake pipe 7 via a connecting rope, and the plug 8 is press-fitted with the outer port of the intake pipe 7. The plug 8 is used to close the outer port of the intake pipe 7.

[0047] Both the ostomy bag body 1 and the inner lining support cover 5 are transparent, allowing direct viewing and adjustment of the irrigation tube's irrigation range. This provides ample irrigation space and ensures thorough cleaning of any overflowing intestinal fluid.

[0048] The opening of the inner lining support cover 5 may be, but is not limited to, circular, and the depth of the inner lining support cover 5 is less than the diameter of its opening, so that the device as a whole is flat and can be covered by clothing.

[0049] The two inlet pipes 6 are directly inserted through external extension tubes, and the length of the extension tubes and the flushing position can be adjusted manually. The air inlet pipe 7 and the inlet pipe 6 are sealed at their contact points with the ostomy bag body 1 and the inner lining support cover 5, respectively.

[0050] Detailed implementation: First, clean and care for the intestinal fistula opening and surrounding skin tissue. The ostomy bag body 1 has a base plate 2 with an appropriately sized hole according to the fistula size, and is securely attached to the surrounding skin tissue. A standard infusion set is connected to a disposable extension tube. The end of the extension tube is cut off, and the extension tube is inserted into the ostomy bag body 1 at the corresponding position of the infusion tube 6, entering the inner lining support cover 5. The appropriate length is adjusted so that the flushing fluid (0.9% saline) flowing from the extension tube can reach the fistula opening and surrounding area. The inner lining suction tube 4 of the ostomy bag drainage port 3 is connected to an external negative pressure device. The plug 8 is opened, the air inlet tube 7 is opened, and negative pressure suction is activated. By adjusting the single / double air inlet and the negative pressure, intestinal contents are suctioned.

[0051] The extension tube can be set to two flushing modes. Mode 1: Continuous flushing, adjusting the drip rate to flush continuously at a rate of 1 drop per second. Mode 2: Intermittent flushing, when a large amount of intestinal contents overflows, the flushing fluid can be fully opened to flush at a linear water flow rate, and the flushed intestinal contents are suctioned away by negative pressure. After flushing, the flushing tube is closed and can be reopened when needed. After the intestinal contents leak out, the flushing fluid is first drained to the area covered by the second cover 10, and then suctioned out by the inner lining suction tube 4. In addition, the position of the inner lining suction tube 4 at the ostomy bag drainage port 3 can be manually adjusted, allowing suction at different positions of the ostomy bag drainage port 3, making it highly operable.

[0052] This sustainable negative pressure irrigation fistula care device has the following advantages: (1) It has a simple structure, is easy to operate and manage, and can be operated by family members after training. The overall shape of the device is flat and can be covered by clothing; (2) The inner liner support cover 5 is made of transparent PET plastic, which allows for direct viewing and adjustment of the irrigation tube's irrigation range. It has a large irrigation space and can effectively clean up any overflowing fluid from the intestine; (3) The negative pressure suction and the air inlet tube 7 form a convection. By adjusting the number of air inlet tubes 7 closed and the intensity of the negative pressure suction, a stable negative pressure and continuous suction can be maintained inside the ostomy bag; (4) Under appropriate negative pressure, the inner liner support cover 5 does not change shape. The shape collapses, and the intestinal overflow fluid flows along the irrigation saline into the second cover 10, and is finally suctioned out by the negative pressure through the inner lining suction tube 4; there are three drainage modes, namely continuous irrigation negative pressure drainage mode, intermittent irrigation negative pressure drainage mode, and no negative pressure drainage mode. (5) The fistula can be kept clean, and the skin and soft tissue around the fistula are protected from the corrosion of digestive juices, which accelerates the growth of granulation tissue and shortens the length of hospital stay. (6) No intestinal overflow fluid accumulates in the ostomy bag, and no intestinal fluid overflows under or outside the stoma base, which significantly reduces the number of ostomy bag changes, saves manpower and resources, and reduces medical costs.

[0053] Example 2

[0054] like Figure 3 As shown, the difference from Embodiment 1 is that in this embodiment, the inlet pipe 6 is provided with a locking mechanism, which is used to lock the extension pipe passing through the inlet pipe 6 to the inlet pipe 6.

[0055] The locking mechanism includes a first clamping arm 11 and a second clamping arm 12. Both the first clamping arm 11 and the second clamping arm 12 have arc-shaped surfaces in their middle sections, forming a circle to clamp the circular extension tube. The first clamping arm 11 is connected to the liquid inlet pipe 6. One end of the first clamping arm 11 is rotatably connected to one end of the second clamping arm 12. The other ends of the first clamping arm 11 and the second clamping arm 12 are respectively provided with a latch and a locking hole. When the first clamping arm 11 and the second clamping arm 12 are joined together, the latch and locking hole connect and lock, clamping the extension tube. After the extension tube extends to the inner liner support cover 5 to a certain length, the locking mechanism fixes the extension tube, preventing subsequent relative movement between the extension tube and the liquid inlet pipe 6.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
