Description

Technical Field

[0001] This utility model relates to the field of intestinal bypass stoma-free devices, specifically a rapid intestinal bypass stoma-free device. Background Technology

[0002] In modern warfare, abdominal injuries account for approximately 3% to 12% of all injuries, mostly penetrating wounds caused by bullets. Colonic injuries typically account for 23% of penetrating abdominal injuries, with the most common sites being the descending colon and sigmoid colon. X-rays taken while wearing a bulletproof vest reveal that these areas are unprotected. Because the colon contains a large number of microorganisms, once perforated, the abdominal cavity is often severely contaminated, and the injured area is larger, significantly increasing the risk of septic shock and even death. Furthermore, due to the greater number of fragments in expanding munitions used in modern warfare, colonic injuries are more likely to occur, resulting in a larger wound area and a mortality rate nearly three times higher than with conventional munitions (4.3%–11.7%).

[0003] In frontline medical settings where resources are scarce, damage control surgery is the first choice. Damage control for intestinal injuries mainly includes hemostasis, improving / reconstructing blood supply, simple closure of the intestinal perforation to control contamination, wrapping and protecting prolapsed intestinal segments, and temporary closure of the abdominal cavity. Among these, controlling bleeding and contamination of intestinal contents should be prioritized. After hemostasis is achieved, the abdominal cavity is flushed with large amounts of saline and multiple drainage tubes are placed for adequate drainage. Due to the frequent occurrence of intestinal edema, to avoid the risk of severe intestinal leakage, traditional methods generally involve primary repair / resection and anastomosis with a proximal prophylactic stoma, or resection of the damaged intestinal segment followed by a proximal stoma and distal closure. However, enterostomies are often accompanied by complications such as edema, dermatitis, bleeding, prolapse, stenosis, parastomal fistula, necrosis, and parahernia. In addition, stoma care, such as changing ostomy bags, places a considerable burden on frontline medical staff.

[0004] Therefore, we propose a rapid intestinal bypass device that can quickly complete intestinal bypass with excellent performance, low cost, and no need for stoma. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies, adapt to practical needs, and provide a rapid intestinal bypass device that eliminates the need for stomas. This addresses the current challenges posed by the frequent occurrence of intestinal edema and the need to avoid the risk of severe intestinal leakage. Traditional methods typically involve primary repair / resection and anastomosis with a proximal prophylactic stoma, or resection of the damaged intestinal segment followed by a proximal stoma and distal closure. However, stomas are often accompanied by complications such as edema, dermatitis, bleeding, prolapse, stenosis, parastomal fistula, necrosis, and parastomal hernia. Furthermore, the ongoing stoma care, including changing ostomy bags, places a significant burden on frontline medical staff.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a rapid intestinal transfer device without stoma, including a drainage tube body, an inner opening of the drainage tube on one side of the bottom of the drainage tube body, a first water bladder installed outside the inner opening of the drainage tube, and a first water injection port connected to one side of the top of the first water bladder.

[0007] A soft support rod is installed on the bottom side of the main body of the drainage tube, and a second water bladder is installed on the outside of the soft support rod. The top of the second water bladder is connected to a second water inlet.

[0008] Preferably, one end of the drainage tube body is connected to a connecting tube, and the other end of the connecting tube is connected to a negative pressure drainage ball.

[0009] Preferably, the negative pressure drainage ball is equipped with anti-backflow valves at both the upper and lower ends.

[0010] Preferably, the bottom of the negative pressure drainage ball is connected to a liquid collection bag, the bottom of the liquid collection bag is connected to a drain outlet, and a push-pull switch is installed on the outside of the drain outlet.

[0011] Preferably, the bottom of the main body of the drainage tube is equipped with an anti-slip protrusion.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This invention effectively drains fecal matter from the proximal intestinal lumen, achieving intestinal diversion quickly and conveniently while avoiding stoma surgery, stoma care, and long-term stoma reduction surgery. Furthermore, this invention can be used with routine surgical drainage consumables such as negative pressure drainage balls and drainage bags, eliminating the need for additional supplies for stoma care such as ostomy bags. It also addresses the challenges posed by traditional methods, which often involve primary repair / resection and anastomosis with a proximal prophylactic stoma, or resection of damaged intestinal segments followed by proximal stoma and distal closure, to prevent severe intestinal leakage due to frequent intestinal edema. Intestinal stomas are often accompanied by complications such as edema, dermatitis, bleeding, prolapse, stenosis, parastomal fistula, necrosis, and parastomal hernia. The added burden of stoma care, including ostomy bag changes, further strains frontline medical staff. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: A rapid intestinal bypass device without ostomy, see [link to documentation]. Figures 1 to 4 The system includes a drainage tube body 1, with an inner drainage port 2 at one bottom side of the body 1. A first water-filled balloon 3 is installed outside the inner drainage port 2, and a first water inlet 13 is connected to one side of the top of the first water-filled balloon 3. A soft support rod 4 is installed at the bottom side of the body 1, and a second water-filled balloon 14 is installed outside the soft support rod 4. A second water inlet 6 is connected to the top of the second water-filled balloon 14. During proximal loop stoma placement, an incision of appropriate size is made at the intended intestinal diversion point, and the drainage tube is inserted into the intestinal lumen. The soft support rod 4 points towards the distal end of the intestinal tract, and the inner drainage port 2 points towards the proximal end of the intestinal tract. After placement, the intestinal... A purse-string suture is made next to the incision to expose the anti-slip protrusion 5. The purse-string is then tightened, and physiological saline is injected into the two inlet ports to inflate the first water bladder 3 around the inner opening 2 of the drainage tube and the second water bladder 14 around the soft straight support rod. The drainage tube is then connected to the negative pressure drainage ball 9, which is connected to the collection bag 10. When performing a proximal end-to-end stoma, the straight support rod and the water bladder around it need to be removed. The drainage tube is then placed into the proximal intestinal lumen, and a purse-string suture is made at the proximal intestinal stump. The purse-string is tightened so that the intestinal wall is wedged between the anti-slip protrusion 5 and the water bladder around the inner opening 2 of the drainage tube to prevent the drainage tube from falling out. The device is then connected.

[0021] After the device is placed, when intestinal fluid and feces flow through the inner opening 2 of the drainage tube in the proximal intestinal tract, the first water bladder 3 around the inner opening can block the passage of fecal fluid. Under the action of negative pressure suction, the fecal fluid is drawn out from the drainage tube into the negative pressure drainage ball 9. When the negative pressure drainage ball 9 is nearly full, squeezing the negative pressure drainage ball 9 causes the internal fecal fluid to be discharged into the collection bag 10. The soft support rod 4 and the surrounding second water bladder 14 can prevent the drainage tube from rotating and shifting in the intestinal lumen.

[0022] For details, see Figure 1 The top of the drainage tube body 1 is connected to one end of the connecting tube 7, and the other end of the connecting tube 7 is connected to the negative pressure drainage ball 9.

[0023] Further, see Figure 1The negative pressure drainage ball 9 has anti-backflow valves 8 installed at both the top and bottom ends.

[0024] It is worth noting that, see Figure 1 The bottom of the negative pressure drainage ball 9 is connected to a liquid collection bag 10, the bottom of the liquid collection bag 10 is connected to a drain port 12, and a push-pull switch 11 is installed on the outside of the drain port 12.

[0025] It is worth noting that, see Figure 1 The bottom of the main body 1 of the drainage tube is equipped with an anti-slip protrusion 5, which can prevent the purse-string suture intestinal wall from slipping.

[0026] When using a rapid intestinal bypass stoma-free device for proximal loop stoma, after making an incision of appropriate size at the intended bypass site, the drainage tube is inserted into the intestinal lumen. The soft support rod 4 points towards the distal end of the intestinal tract, and the inner opening 2 of the drainage tube points towards the proximal end. After placement, a purse-string suture is made next to the intestinal incision to expose the anti-slip protrusion 5. The purse-string is then tightened, and physiological saline is injected through the two infusion ports to inflate the first water sac 3 around the inner opening 2 of the drainage tube and the second water sac 14 around the soft support rod. The drainage tube is then connected to the negative pressure drainage ball 9, which is connected to the collection bag 10. When performing a proximal end stoma, the support rod and the surrounding water sac need to be removed. The drainage tube is then placed into the proximal intestinal lumen, and a purse-string suture is made at the proximal intestinal stump. The purse-string is tightened so that the intestinal wall is wedged between the anti-slip protrusion 5 and the water sac around the inner opening 2 of the drainage tube to prevent the drainage tube from dislodging. The device is then connected. After the device is placed, when intestinal fluid and feces flow through the inner opening 2 of the drainage tube in the proximal intestinal tract, the first water bladder 3 around the inner opening can block the passage of fecal fluid. Under the negative pressure suction, the fecal fluid is drawn out from the drainage tube to the negative pressure drainage ball 9. When the negative pressure drainage ball 9 is nearly full, the negative pressure drainage ball 9 is squeezed to drain the internal fecal fluid into the collection bag 10. The soft support rod 4 and the surrounding second water bladder 14 can prevent the drainage tube from rotating and shifting in the intestinal lumen. The anti-slip protrusion 5 can prevent the purse-string sutured intestinal wall from slipping.
