Description

Technical Field

[0001] The utility model belongs to the technical field of intestinal stoma, and in particular relates to a double-cavity intestinal stoma connector. Background Art

[0002] The incidence of complications such as anastomotic fistula, rectovaginal fistula, and radiation enteritis after colorectal cancer treatment is relatively high. Therefore, doctors will perform a temporary loop double-lumen stoma to divert feces during radical surgery for rectal cancer, keep the distal intestine away from fecal contamination, promote healing of the rectal anastomosis, and avoid the occurrence of complications.

[0003] Three months after radical surgery for rectal cancer, the anastomosis has healed well. At this time, the doctor will close the temporary loop double-lumen stoma to allow the patient to resume defecation from the anus. Before surgery, the patient needs to undergo a series of examinations such as colonoscopy, defecography, barium enema, and rectal anorectal manometry to assess whether the distal intestinal tract is unobstructed and the anal control ability, that is, whether the patient can defecate normally after the stoma is closed. But the problem is that these examinations are only indirect evaluations and cannot thoroughly reflect the true condition of the patient's distal intestinal or anal function. For patients who have undergone neoadjuvant treatment before surgery, even if the results of the above examinations are normal before surgery, after the stoma is closed, they may have poor control of stool due to intestinal disuse atrophy, intestinal obstruction, and recurrence of anastomotic fistula, causing severe abdominal and pelvic infection, and even life-threatening.

[0004] The invention patent with application number CN202311333800.0 discloses an enterostomy connector, including a connecting ball, the inner side of which is a spherical hollow structure, the two sides of which are symmetrically fixedly connected to connecting pipes, and the side of which is provided with a connecting port; a three-way ball valve, which is rotatably connected to the inner side of the connecting ball; an annular airbag, which is sleeved on one end of the connecting pipe away from the connecting ball, and the side of the annular airbag is fixedly connected to a ventilating tube, and the intestinal condition after enterostomy retraction surgery is simulated by reversing the ball valve. However, the disadvantage of this type of stoma connector is that there is a gap between the ball valve and the valve core, and excrement is easily filled into the gap, resulting in the valve core rotating unsmoothly. At the same time, the excrement in the gap is not easy to be discharged, resulting in the excrement producing a large number of bacteria in the valve core. When the valve core is connected to the distal end of the stoma, the risk of infection of the intestine between the distal end of the stoma and the cylinder door will increase. Summary of the invention

[0005] In view of the above shortcomings, the technical problem to be solved by the utility model is to provide a double-lumen enterostomy connector, which adopts a rotating pipe structure to change the flow direction of excreta in the enterostomy connector to prevent excreta from remaining in the enterostomy connector.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A double-lumen enterostomy connector comprises a stoma connector and an inlet pipe and an outlet pipe group which are detachably connected to the stoma connector respectively. The outlet pipe group is rotatably mounted on the inlet pipe. A closing port and a waste outlet are provided on the outlet pipe group. The closing port or the waste outlet is connected to the stoma connector by rotating the outlet pipe group.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] A double-lumen intestinal stoma connector comprises a stoma connector 1, an inlet tube 2, and an outlet tube group 3. The inlet tube 2 and the outlet tube group 3 are respectively detachably connected to the stoma connector 1 to form an adjustment tube. The outlet tube group 3 comprises a connecting port 3-4, a closing port 3-1, and a waste outlet 3-2. The connecting port 3-4 is rotatably mounted on the inlet tube 2. The closing port 3-1 is in a closed state, and the waste outlet 3-2 is in an open state. By rotating the outlet tube group 3, the closing port 3-1 or the waste outlet 3-2 is connected to the stoma connector 1, thereby changing the discharge direction of excrement in the intestinal stoma connector.

[0025] The outlet pipe group 3 is in a T-shaped structure, the axis of the closed port 3-1 and the axis of the waste outlet 3-2 are located on the same straight line, and the axis of the connecting port 3-4 is arranged perpendicular to the axis of the closed port 3-1. A baffle 3-3 is arranged in the outlet pipe group 3, and the baffle 3-3 is arranged on one side of the closed port 3-1, so that the closed port 3-1 is closed, ensuring that the flow direction of the excrement in the regulating pipe always flows from the inlet pipe 2 to the waste outlet 3-2. A feces bag is connected to the waste outlet 3-2, and the feces is directly discharged through the waste outlet 3-2.

[0026] The baffle 3 - 3 is in an arc shape, so that the internal flow channel of the outlet pipe group 3 - 1 is smoother, preventing excrement from being retained in the outlet pipe group 3 and preventing the retained excrement from generating excessive bacteria.

[0027] In order to facilitate the connection of the closed port 3-1 and the waste outlet 3-2 to the stoma connection piece 1, end covers 4 are installed on the outside of the closed port 3-1 and the waste outlet 3-2, and the end covers are connected to the stoma connector 1-1 of the stoma connection piece 1 through threads, so that the closed port 3-1 and the waste outlet 3-2 are abutted against the end of the stoma connector 1-1, so that the stoma connector 1-1 is connected with the closed port 3-1 and the waste outlet 3-2.

[0028] A limiting ring 3-5 is connected to the end faces of the closed port 3-1 and the waste outlet 3-2, and the end cover 4 is limitedly installed on the closed port 3-1 or the waste outlet 3-2 through the limiting ring 3-5. When the end cover 4 is fastened to the stoma joint 1-1 by threads, the limiting ring 3-5 abuts against the stoma joint 1-1 of the stoma connector 1, thereby realizing the connection between the stoma joint 1-1 and the closed port 3-1 and the waste outlet 3-2.

[0029] A limiting ring is also connected to the front end of the inlet pipe 2, and the inlet pipe 2 is abutted against the stoma joint 1-1 through the end cover 4. A connecting ring 2-1 is provided at the rear end of the inlet pipe 2, and the connecting port 3-4 is rotatably mounted on the connecting ring 2-1, and the sealing of the connection between the connecting port 3-4 and the connecting ring 2-1 is ensured by a sealing ring.

[0030] The stoma connector 1 includes two stoma connectors 1-1 and a connector base 1-3. An installation cavity 1-4 is provided in the connector base 1-3. The two stoma connectors 1-1 are arranged in the installation cavity 1-4. The two stoma connectors 1-1 are respectively connected to the proximal end and the distal end of the intestinal stoma 5. The inlet pipe 2 and the outlet pipe group 3 are respectively detachably connected to the two stoma connectors 1-1.

[0031] When there is a lot of excrement in the intestine, it is easy for the intestine to separate from the stoma connector when the intestine is fixed to the outside of the stoma connector by an ordinary air bag. In order to ensure the connection stability between the intestine and the stoma connector, an air bag 1-2 is provided on the inner wall of the installation cavity 1-4. The air bag 1-2 is arranged on the outside of the stoma connector 1-1. When the air bag 1-2 is inflated, the air bag 1-2 expands toward the stoma connector 1-1, and the intestinal stoma is abutted against the side wall of the stoma connector 1-1, thereby stably fixing the intestinal stoma on the stoma connector 1-1.

[0032] The stoma connector of this embodiment is used to connect an incompletely cut intestinal stoma to prevent tearing at the intestinal incision when the connector is connected to the proximal and distal ends of the intestinal stoma, and the spacing between adjacent stoma connectors 1-1 is controlled to be 0.5-1cm. At the same time, the airbag 1-2 is in an 8-shaped structure, and the two rings of the airbag 1-2 are hollow to prevent interference between the airbag 1-2 and the intestinal stoma connection.

[0033] To ensure smooth blood supply to the intestinal wall, a notch 1-6 is provided on the outer wall of the airbag 1-2 facing the stoma connector 1-1. The notch 1-6 and the hollow structure in the middle of the airbag 1-2 ensure smooth blood supply to the intestine.

[0034] An annular protrusion 1-5 is provided on the outer side wall of the stoma connector 1-1, and the intestinal stoma is limited by the annular protrusion 1-5 to prevent the intestinal stoma from being separated from the stoma connector 1-1, and the annular protrusion 1-5 is located below the airbag 1-2. Preferably, the airbag 1-2 is arranged with an inclined surface facing the upper end of the annular protrusion 1-5, and the intestine is limited by the cooperation of the airbag 1-2 and the annular protrusion 1-5 to ensure that the intestine and the stoma connector can be stably connected.

[0035] The working principle of this enterostomy connector is as follows:

[0036] (1) In the early stage of treatment, the excrement in the intestine is discharged directly through the stoma connector. At this time, the intestinal stoma is first connected to the two stoma connectors 1-1. During the connection process, the intestinal stoma should be prevented from tearing;

[0037] (2) Inflate the airbag 1-2 to fix the intestinal stoma on the stoma connector 1-1;

[0038] (3) Adjust the outlet tube group 3 so that the closed port 3-1 of the outlet tube group 3 is consistent with the inlet of the inlet tube 2, and connect the closed port 3-1 and the inlet of the inlet tube 2 to the stoma connector 1-1 through the end cap 4. At this time, the excreta flows from the proximal end of the intestinal stoma into the inlet tube 2, and then flows from the inlet tube 2 into the waste outlet 3-2, and the excreta is discharged from the waste outlet 3-2;

[0039] (4) In the later stage of treatment, it is necessary to test whether the excreta in the intestine can be discharged directly through the anus. The outlet tube group 3 and the inlet tube 2 are removed from the stoma connector 1-1, and the outlet tube group 3 is adjusted so that the waste outlet 3-2 of the outlet tube group 3 is consistent with the inlet of the inlet tube 2. The waste outlet 3-2 and the inlet of the inlet tube 2 are connected to the stoma connector 1-1 through the end cover 4. At this time, the excreta flows from the proximal end of the intestinal stoma into the inlet tube 2, and then from the inlet tube 2 into the waste outlet 3-2, and then from the waste outlet 3-2 into the distal end of the intestinal stoma, so that the excreta is discharged through the patient's anus.
