Description

Technical Field

[0001] The present invention relates to the technical field of intestinal obstruction catheters, and in particular to a novel intestinal obstruction catheter placed through abdominal wall-gastrostomy. Background Art

[0002] An intestinal obstruction catheter is a medical device used to treat intestinal obstruction. It is usually inserted into the stomach or small intestine through the nasal cavity to relieve obstruction and relieve symptoms. Intestinal obstruction catheters are usually made of soft plastic or silicone to facilitate movement in the digestive tract and reduce irritation. The catheter uses the principle of negative pressure to suck out fluid, gas, and contents accumulated in the intestine, thereby reducing abdominal distension and pain, helping to restore intestinal peristalsis, and promoting normal intestinal function. It is often used for mechanical intestinal obstruction, such as obstruction caused by tumors and adhesions, and may also be used for postoperative intestinal paralysis or functional intestinal obstruction.

[0003] When using the intestinal obstruction catheter in the prior art, a guide wire and a drainage tube need to be inserted from the patient's nasal cavity, through the esophagus and stomach into the duodenum, and then into the dilated and obstructed small intestine segment to achieve the effect of treating and relieving the patient's intestinal obstruction; however, the intestinal obstruction catheter is relatively thick, and long-term retention can easily cause discomfort in the pharynx and nasal cavity, and even cause pneumonia. If the patient has underlying diseases or damage in the nasopharynx or esophagus, the intestinal obstruction catheter cannot be placed into the gastrointestinal tract through the esophagus from the nostrils. At this time, the intestinal obstruction catheter in the prior art cannot meet the needs of such patients for the treatment of intestinal obstruction. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a new intestinal obstruction catheter placed through the abdominal wall-gastrostomy.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A new intestinal obstruction catheter placed through the abdominal wall-gastrostomy comprises a sleeve, an abdomen and a stomach, one end of the sleeve passes through the abdomen and the stomach in sequence, a first fixing mechanism is provided at the end of the sleeve located in the stomach, a first through hole and a second through hole are provided inside the sleeve, a catheter body and a nutrition tube are respectively installed inside the first through hole and the second through hole, a fixed end is installed at the end of the sleeve located outside the abdomen, a limiting mechanism for limiting and fixing the catheter body and the nutrition tube is provided at the end of the fixed end away from the abdomen, a second fixing mechanism is provided on the outer wall of the fixed end, a connecting port is provided at the end of the catheter body located outside the abdomen, a sheath is inserted inside the connecting port.

[0007] Optionally, a front balloon and a rear balloon are provided at the other end of the catheter body, and the other end of the catheter body is limited by abutting against the inner wall of the intestine through the front balloon or the rear balloon.

[0008] Optionally, two fixing seats are installed on the outer wall of one end of the connecting port away from the catheter body, and sealing covers are rotatably installed inside the two fixing seats. Rubber blocks are installed on the outer walls of the two sealing covers on one side close to the connecting port.

[0009] Optionally, the first fixing mechanism includes an air bag installed on the outer wall of one end of the sleeve located inside the stomach, the outer wall of the fixed end is provided with an air supply port connected to the air bag, and a first rubber stopper is provided inside the air supply port.

[0010] Optionally, the second fixing mechanism includes multiple rotating plates, and the multiple rotating plates are rotatably installed on the outer wall of the fixed end through a damping shaft. The outer walls on one side of the multiple rotating plates are provided with an adhesion part, and the outer walls on the other side of the multiple rotating plates are assisted by an abdominal belt and fixed to the abdomen. A suture part is provided at one end of the fixed end close to the multiple adhesion parts.

[0011] Optionally, a circular groove is provided at one end of the fixed end close to the sleeve, and two injection ports connected to the circular groove are provided at one end of the fixed end away from the sleeve, and a second rubber plug is installed inside the two injection ports.

[0012] Optionally, the limiting mechanism includes a first threaded sleeve and a second threaded sleeve, and the first threaded sleeve and the second threaded sleeve are both arranged on the outer wall of the fixed end away from the sleeve, and the first threaded sleeve and the second threaded sleeve are respectively in the same straight line with the first through hole and the second through hole inside the sleeve.

[0013] Optionally, a plurality of adjustment grooves are provided inside the first threaded sleeve and the second threaded sleeve, and two sealing rings are installed on the inner walls of the first threaded sleeve and the second threaded sleeve.

[0014] Optionally, the outer walls of the catheter body and the nutrition tube are respectively covered with a first sealing sleeve and a second sealing sleeve, and the first sealing sleeve and the second sealing sleeve are respectively threadedly connected to the outer walls of the first threaded sleeve and the second threaded sleeve.

[0015] The beneficial effects of the present invention are: 1. In this invention, a hole is directly made in the patient's abdomen and stomach under the guidance of a gastroscope, and a sleeve is installed in the patient's abdomen and stomach. Then, the catheter body is passed through the inside of the sleeve and placed in the patient's intestine, thereby avoiding directly passing the catheter body through the patient's esophagus, which would cause great pain to patients with damaged esophagus. In addition, the catheter body can be combined with a nutrition tube, allowing the patient to take in necessary nutrients, avoiding malnutrition during treatment and thereby prolonging the patient's survival time.

[0016] 2.

DETAILED DESCRIPTION

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Reference Figures 1-10 A new type of intestinal obstruction catheter placed through the abdominal wall-gastrostomy comprises a sleeve 4, an abdomen 1 and a stomach 2, one end of the sleeve 4 passes through the abdomen 1 and the stomach 2 in sequence, a first fixing mechanism is provided at the end of the sleeve 4 located at the stomach 2, a first through hole 26 and a second through hole 27 are provided inside the sleeve 4, a catheter body 7 and a nutrition tube 6 are installed inside the first through hole 26 and the second through hole 27 respectively, a fixed end 30 is provided at the end of the sleeve 4 located outside the abdomen 1, a limiting mechanism for limiting and fixing the catheter body 7 and the nutrition tube 6 is provided at the end of the fixed end 30 away from the abdomen 1, a second fixing mechanism is provided on the outer wall of the fixed end 30, a connecting port 21 is provided at the end of the catheter body 7 located outside the abdomen 1, a sheath 25 is inserted inside the connecting port 21. When using the cannula 4, medical staff need to open holes at appropriate positions in the patient's abdomen 1 and stomach 2, pass one end of the cannula 4 through the abdomen 1 and stomach 2 in sequence, and then insert the catheter body 7 and the feeding tube 6 from the corresponding first through hole 26 and second through hole 27 and extend them into the stomach 2.

[0024] In this embodiment, the length of the nutrition tube 6 from the sleeve 4 to the inside of the stomach 2 is greater than 40 cm, and the diameter of the nutrition tube 6 is the same as that of the stomach tube in the prior art; the catheter body 7 is an intestinal obstruction catheter in the prior art.

[0025] As a technical optimization solution of the present invention, the upper and lower ends of the stomach 2 are connected to the intestine 3 inside the human body, and the other end of the catheter body 7 extends into the inside of the intestine 3.

[0026] As a technical optimization solution of the present invention, a front balloon 9 and a rear balloon 10 are provided at the other end of the catheter body 7 , and the other end of the catheter body 7 is limited by abutting against the inner wall of the intestine 3 through the front balloon 9 or the rear balloon 10 .

[0027] As a technical optimization solution of the present invention, two fixing seats 22 are installed on the outer wall of the end of the connecting port 21 away from the catheter body 7, and sealing covers 23 are rotatably installed inside the two fixing seats 22. Rubber blocks 24 are installed on the outer wall of the two sealing covers 23 on the side close to the connecting port 21. After one end of the catheter body 7 passes through the first through hole 26 and enters the stomach 2, the sheath tube 25 is inserted into the inside of the connecting port 21, and then the guide tube, guide wire and other components whose diameter is smaller than the inner diameter of the sheath tube 25 are passed through the inside of the sheath tube 25 and extended to the inside of the catheter body 7. The end of the catheter body 7 entering the stomach 2 is controlled so that the end of the catheter body 7 with the front balloon 9 and the rear balloon 10 moves downward to the inside of the intestine 3. The medical staff supplies air to the air port designated at one end of the outside of the catheter body 7, so that the front balloon 9 or the rear balloon 10 is inflated, so that its outer wall is in close contact with the inner wall of the intestine 3, so that the catheter body 7 can be limited and fixed at the designated position inside the intestine 3 after entering the designated position inside the intestine 3, thereby improving the stability of the use of the catheter body 7.

[0028] As a technical optimization solution of the present invention, the first fixing mechanism includes an airbag 5 mounted on the outer wall of one end of the cannula 4 located inside the stomach 2. The outer wall of the fixed end 30 is provided with an air supply port 12 connected to the airbag 5, and the interior of the air supply port 12 is provided with a first rubber stopper 15. After one end of the cannula 4 is passed through the abdomen 1 and stomach 2, the medical staff opens the first rubber stopper 15 and supplies air to the interior of the air supply port 12, causing the airbag 5 to inflate inside the stomach 2. With the expansion of the airbag 5, its outer wall abuts against the inner wall of the stomach 2, thereby achieving the effect of limiting and fixing the end of the cannula 4 inside the stomach 2.

[0029] As a technical optimization solution of the present invention, the second fixing mechanism includes a plurality of rotating plates 11, and the plurality of rotating plates 11 are rotatably installed on the outer wall of the fixed end 30 through a damping shaft. The outer walls on one side of the plurality of rotating plates 11 are provided with an adhesion portion 28, and the outer walls on the other side of the plurality of rotating plates 11 are assisted by the provided abdominal belt 8 to be connected and fixed to the abdomen 1, and a suture portion 31 is provided at one end of the fixed end 30 close to the plurality of adhesion portions 28. After the end of the sleeve 4 located inside the stomach 2 is limited and fixed by the airbag 5 of the first fixing mechanism, the multiple rotating plates 11 are rotated to a state parallel to the abdomen 1, and the multiple rotating plates 11 are adhered to the outer wall of the abdomen 1 by means of the corresponding adhesion parts 28, so that the multiple rotating plates 11 can be adhered to the outer wall of the abdomen 1, thereby achieving the effect of preliminarily fixing the end of the sleeve 4 located outside the abdomen 1; and in order to improve the connection stability between the sleeve 4 and the outside of the abdomen 1, the medical staff can suture the suture part 31 to the outside of the patient's abdomen by suturing; after the suture part 31 is sutured to the patient's abdomen, the abdominal belt 8 is used to auxiliary fix the outer wall of the side of the multiple rotating plates 11 away from the abdomen 1, so that it can protect the suture part, and further connect and fix the sleeve 4 to the abdomen 1, thereby improving the fixing effect of the sleeve 4 and avoiding the problem that the stability of the sleeve 4 cannot be guaranteed after installation.

[0030] As a technical optimization solution of the present invention, a circular groove 29 is provided at one end of the fixed end 30 close to the sleeve 4, and two injection ports 19 connected to the circular groove 29 are provided at one end of the fixed end 30 away from the sleeve 4. A second rubber stopper 20 is installed inside the two injection ports 19. After the sleeve 4 is installed on the abdomen 1 and the stomach 2, medical staff need to regularly use drugs to reduce inflammation and disinfect the wound area of ​​the abdomen 1. Since the end of the fixed end 30 close to the sleeve 4 is in contact with the wound area of ​​the abdomen 1 after installation, the two second rubber stoppers 20 can be opened directly to inject drugs into the interior of the fixed end 30 with the help of the two injection ports 19. After the drugs enter the interior of the fixed end 30, they will be directly discharged to the wound area through the circular groove 29, and the drugs will be quickly administered to the patient's wound area, thereby improving the efficiency of reducing inflammation and disinfecting the wound area, and avoiding the problem of accidentally touching the sleeve 4 during the administration of drugs to the patient's wound area, thereby increasing the patient's pain.

[0031] As a technical optimization solution of the present invention, the limiting mechanism includes a first threaded sleeve 16 and a second threaded sleeve 17. The first threaded sleeve 16 and the second threaded sleeve 17 are both arranged on the outer wall of the fixed end 30 away from the sleeve 4, and the first threaded sleeve 16 and the second threaded sleeve 17 are respectively in the same straight line with the first through hole 26 and the second through hole 27 inside the sleeve 4.

[0032] As a technical optimization solution of the present invention, a plurality of adjustment grooves are provided inside the first threaded sleeve 16 and the second threaded sleeve 17 , and two sealing rings 18 are installed on the inner walls of the first threaded sleeve 16 and the second threaded sleeve 17 .

[0033] As a technical optimization solution of the present invention, the outer walls of the catheter body 7 and the feeding tube 6 are respectively covered with a first sealing sleeve 13 and a second sealing sleeve 14, and the first sealing sleeve 13 and the second sealing sleeve 14 are respectively threadedly connected to the outer walls of the first threaded sleeve 16 and the second threaded sleeve 17. Figure 4 As shown, before the catheter body 7 and the nutrition tube 6 are passed through the corresponding first through hole 26 and the second through hole 27, the first sealing sleeve 13 and the second sealing sleeve 14 can be slidably sleeved on the surface of the catheter body 7 and the nutrition tube 6 until one end of the catheter body 7 and the nutrition tube 6 enter the appropriate position inside the intestine 3 and the stomach 2 respectively. By screwing the first sealing sleeve 13 and the second sealing sleeve 14 in sequence, they are threadedly connected with the first threaded sleeve 16 and the second threaded sleeve 17 respectively, so that the positions of the catheter body 7 and the nutrition tube 6 can be limited and fixed respectively, thereby preventing the catheter body 7 and the nutrition tube 6 from shaking during subsequent use.

[0034] In the present invention, when the user uses the device, when it is necessary to use the catheter body 7 to treat the intestine 3 below the stomach 2, and use the nutrition tube 6 to deliver food or other nutrients to the stomach 2, in order to facilitate the two to be carried out simultaneously in the patient's body and reduce the pain suffered by the patient, the medical staff can pre-open holes at designated positions on the patient's abdomen 1 and stomach 2, and then tear off the stickers used to protect the adhesion part 28 on the outer wall of one side of the multiple rotating plates 11, and then pass one end of the sleeve 4 through the abdomen 1 and stomach 2 in sequence until one end of the sleeve 4 enters the stomach 2 to a suitable length. At this time, the adhesive portions 28 on the outer walls of one side of the plurality of rotating plates 11 are adhered to the outer wall of the patient's abdomen 1, so that the end of the sleeve 4 located on the outer wall of the patient's abdomen 1 is pre-adhesively fixed. In order to improve the connection stability between the sleeve 4 and the outside of the abdomen 1, the medical staff can sew the suture portion 31 to the outside of the patient's abdomen by suturing. Then, the first rubber stopper 15 inside the gas delivery port 12 can be removed, and gas can be supplied to the inside of the gas delivery port 12, so that the airbag 5 is expanded and deployed in the patient's stomach 2, thereby limiting and fixing the end of the sleeve 4 inside the patient's stomach 2. Then, the medical staff can use the abdominal belt 8 to assist in fixing the outer wall of the multiple rotating plates 11 away from the abdomen 1, so that it can protect the suture site, and further connect and fix the sleeve 4 and the abdomen 1, thereby improving the fixing effect of the sleeve 4 and avoiding the problem of the sleeve 4 not being able to ensure stability after installation.

[0035] After the sleeve 4 is installed on the patient's abdomen 1 and stomach 2, the first sealing sleeve 13 and the second sealing sleeve 14 can be slid onto the surface of the catheter body 7 and the feeding tube 6 until one end of the catheter body 7 and the feeding tube 6 pass through the first through hole 26 and the second through hole 27 respectively and enter the appropriate position inside the intestine 3 and the stomach 2. Then, the second sealing sleeve 14 is screwed to be threadedly connected with the second threaded sleeve 17 to limit and fix the position of the feeding tube 6, so that food or other nutrients can be delivered to the patient's stomach 2 with the help of the feeding tube 6. When the feeding tube 6 is not needed, the end of the feeding tube 6 located outside the abdomen 1 can be sealed with the sealing plug matched with the feeding tube 6.

[0036] After one end of the catheter body 7 enters the stomach 2, Figure 5 As shown, the two sealing covers 23 are rotated upward and downward respectively, driving the two semicircular rubber blocks 24 to rotate outward from the inside of the connecting port 21, thereby releasing the blockage of the connecting port 21. Then, one end of the sheath tube 25 can be inserted into the inside of the connecting port 21 between the two rubber blocks 24. With the help of the close contact between the two rubber blocks 24 and the outer wall of the sheath tube 25, the position of the sheath tube 25 after being inserted into the inside of the connecting port 21 can be automatically abutted and limited. Subsequently, the guide tube, guide wire and other components of the sheath tube 25 with a diameter smaller than the inner diameter of the sheath tube 25 can be removed from the sheath tube 25. 5 passes through the interior of the catheter body 7 and extends to the interior of the catheter body 7. The end of the catheter body 7 entering the stomach 2 is controlled so that the end of the catheter body 7 with the front balloon 9 and the rear balloon 10 moves downward to the interior of the intestine 3. The medical staff supplies air to the designated air port at the external end of the catheter body 7 to inflate the front balloon 9 or the rear balloon 10 so that its outer wall is in close contact with the inner wall of the intestine 3. This can achieve the effect of limiting and fixing the catheter body 7 at the designated position inside the intestine 3 after it enters the internal part of the intestine 3, thereby improving the stability of the catheter body 7 during use. After the position of the catheter body 7 inside the intestine 3 is adjusted by means of the sheath 25 and its supporting components, the sheath 25 can be removed from the inside of the connecting port 21, and the two sealing covers 23 and the rubber block 24 can be rotated and reset so that the two sealing covers 23 and the rubber block 24 cooperate with each other to seal the connecting port 21, thereby improving the applicability of the two sealing covers 23 and the rubber block 24; then the first sealing sleeve 13 is threadedly connected to the first threaded sleeve 16, so that the end of the catheter body 7 outside the patient's abdomen 1 can be limited and fixed, which is convenient for the subsequent use of the catheter body 7. When it is necessary to adjust the position of the catheter body 7 inside the intestine 3, the first sealing sleeve 13 can be loosened so that the catheter body 7 can continue to move back and forth inside the first through hole 26, and the length of the catheter body 7 can be adjusted again by means of the sheath 25 and its supporting components, so as to achieve the effect of flexibly adjusting the position of the catheter body 7 inside the intestine 3, thereby facilitating the use of the catheter body 7.

[0037] After the sleeve 4 is installed on the abdomen 1 and the stomach 2, medical staff need to use drugs regularly to reduce inflammation and disinfect the wound area of ​​the abdomen 1. Since the fixed end 30 of the sleeve 4 is close to the end of the sleeve 4 and contacts the wound area of ​​the abdomen 1 after installation, the two second rubber stoppers 20 can be opened directly, and the two injection ports 19 can be used to inject drugs into the interior of the fixed end 30. After the drugs enter the interior of the fixed end 30, they will be directly discharged to the wound area through the circular groove 29, and the drugs will be quickly administered to the patient's wound area, thereby improving the efficiency of reducing inflammation and disinfection of the wound area and avoiding the problem of accidentally touching the sleeve 4 during the process of administering drugs to the patient's wound area, thereby increasing the patient's pain.

[0038] Since the plurality of rotating plates 11 are rotatably connected to the outer wall of the fixed end 30 through the damping shaft, the sleeve 4 can be rotated 90 degrees toward the fixed end 30 to be in a retracted state when not in use, so as to facilitate storage of the sleeve 4; and when the sleeve 4 needs to be displayed, the plurality of rotating plates 11 after rotation adjustment can be retracted. Figure 7 As shown, the sleeve 4 can be placed on the top of the display platform with the help of multiple rotating plates 11 after rotation adjustment, which is convenient for placing the sleeve 4 so that other people can observe the airbag 5 and other components of the sleeve 4; Figure 8 As shown, at this time, multiple rotating plates 11 are in use and can be directly placed on the top of the display platform. With the help of two of the rotating plates 11, the fixed end 30 is supported, making it convenient for other personnel to observe the first through hole 26, the second through hole 27, the first threaded sleeve 16, the second threaded sleeve 17 and other components of the sleeve 4.
