Description

Technical Field

[0001] The utility model relates to a double-cavity stoma supporting device with intracavity flushing and flow diversion functions. Background Art

[0002] Double-lumen stoma is a commonly used surgical method in gastrointestinal surgery. The surgical process is to drag the intestine out to the outside of the abdominal wall, cut the intestine longitudinally to form two openings, and then suture the serosal layer of the intestinal wall to the peritoneum and subcutaneous tissue respectively. Finally, the proximal end of the stump helps the intestinal contents to be discharged, and the distal end helps the gastrointestinal mucus to be discharged. Double-lumen stoma is mainly used for patients with obstruction of the distal intestine or severe adhesion of distal tumor lesions to surrounding tissues that cannot be removed. Patients with distal intestinal rupture that cannot be sutured in the first stage may also undergo a proximal double-lumen stoma. Currently, after a double-lumen stoma, a rigid tube is placed below the stoma. The two ends of the rigid tube are bent into a ring, and the ring is closed above the stoma. The purpose of placing the rigid tube is to serve as a support device to prevent the double-lumen stoma from retracting into the subcutaneous tissue. Then a stoma bag is pasted on the skin around the stoma to facilitate the collection of intestinal contents discharged from the stoma.

[0003] When the patient has gastrointestinal dysfunction or the intestinal contents are relatively dry, the double-lumen stoma may be blocked, resulting in the inability to discharge the intestinal contents, which in turn leads to intestinal obstruction. The patient will experience abdominal pain, nausea, vomiting, and cessation of defecation through the stoma. At this time, the patient is usually given paraffin oil or other laxatives orally. The effect is poor for some patients, and it is necessary to insert a finger into the intestinal tube to dig out the intestinal contents to relieve the obstruction. However, it is inconvenient to clean deeper feces, and only shallower feces can be cleaned, and then cleaned after the intestines peristalsis outward. The cleaning process is long and the effect is poor. Utility Model Content

The bag opening of the drainage bag 8 is connected to the inner ring of the outer annular disk 7, and the bottom of the drainage bag 8 is provided with a diversion port 10.

[0027] The flushing and suction assembly includes a syringe 11 and two water injection pipes 12. A piston 13 and a push rod 14 are arranged in the syringe 11. One end of the push rod 14 is connected to the piston 13, and the other end of the push rod 14 is provided with a push handle 15. A drain pipe 16 is arranged on the side wall of the syringe 11, and a drain valve 17 is arranged on the drain pipe 16. Two interfaces are arranged at the end of the syringe 11, each of which is provided with a control valve 18, and each interface is connected to an inner tube 1 9, the inner cannula 19 has three lumens, namely, an inflation cavity 20, an injection cavity 21 and a suction cavity 22. The suction cavity 22 of the inner cannula 19 is connected to the interface. The upper outer wall of the inner cannula 19 is connected to the inflation interface 23. The end outer wall of the inner cannula 19 is provided with a blocking airbag 24. The inflation interface 23 is connected to the blocking airbag 24 through the inflation cavity 20. The upper part of the inner cannula 19 is provided with an insertion port 25, and the insertion port 25 is connected to the injection cavity 21.

[0028] The two water injection pipes 12 are respectively inserted into the injection cavity 21 of the inner insert tube 19 through the insertion port 25. The lower part of the water injection pipe 12 is connected to a disturbance pipe 26, and a plurality of water injection holes 27 are evenly distributed on the disturbance pipe 26. The outer diameters of the water injection pipe 12 and the disturbance pipe 26 are equal to the diameter of the injection cavity 21.

[0029] When the double-lumen stoma of this embodiment is in use, the fixed chassis 1 is adhered to the periphery of the stoma through the adhesive layer on the back side, the inner ring of the fixed chassis 1 can pass through the intestinal tube, the swivel 2 can rotate on the inner ring of the fixed chassis 1, the support rod 3 can be removed from the swivel 2, and then the support rod 3 is passed through the intestinal tube, and the two ends of the support rod 3 are fixed to the two bayonet holes 4 on the swivel 2. At this time, the superior arc-shaped air bag can support the intestinal tube, and the concave groove of the superior arc-shaped air bag is used to place the intestinal tube. At this time, the support of the intestinal tube is completed, and finally the outer annular disk 7 is installed on the docking ring 6 of the fixed chassis 1 through the snap ring 9. After fixing, the intestinal contents of the double-lumen stoma can be discharged into the drainage bag 8 through the inner ring of the fixed chassis 1. At this time, the diversion port 10 at the bottom of the drainage bag 8 is in a closed state. When the drainage bag 8 needs to be emptied, the diversion port 10 can be opened for discharge.

[0031] In addition, when it is necessary to flush the intestinal contents of the double-lumen stoma to relieve the obstruction, the outer annular disk 7 and the drainage bag 8 can be removed, and the flushing and suction assembly can be used for operation, specifically as follows: the two inner cannulas 19 are respectively inserted into the intestinal cavities at both ends, and then gas is injected through the inflation interface 23, and the gas enters the blocking airbag 24 through the inflation cavity 20, and the blocking airbag 24 is expanded and blocks the intestinal tract; then the water injection tube 12 and the disturbance tube 26 are respectively inserted from the insertion port 25 into the injection cavity 21 of the inner cannula 19, and the flushing liquid is injected through the water injection tube 12, and the flushing liquid flows into the intestinal cavity through the water injection hole 27, and the flushing liquid has an effect on the intestinal contents. The intestinal contents (feces and water) are flushed and diluted, and suction begins after flushing, the drain valve 17 is closed, the push rod 14 is pulled, and the piston 13 is used to generate negative pressure in the injection cylinder, so that the suction chamber 22 of the inner tube 19 starts suction, and the intestinal contents are attracted to the injection cylinder. When the intestinal contents of the injection cylinder need to be discharged, the control valve 18 is closed, the drain valve 17 is opened, and the push rod 14 is pushed to push the intestinal contents out. In addition, the material of the disturbance tube 26 is harder than that of the water injection tube 12, and the disturbance tube 26 can be passed through the injection chamber 21 and directly inserted into the feces for flushing, which has the effect of mechanical damage and is convenient for flushing.
