Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable air bag-fixed intestinal obstruction catheter. Background Art

[0002] Intestinal obstruction is caused by intestinal or extraintestinal factors that prevent the smooth passage of intestinal contents. The main clinical manifestations are abdominal pain, bloating, nausea, and vomiting. Therefore, one of the more important treatment methods is gastrointestinal decompression, that is, inserting a gastric tube to drain gastric juice out of the body, reduce tension in the gastrointestinal tract, and facilitate rapid recovery of the intestine.

[0003] Generally speaking, a gastric tube needs to be placed within about a week after intestinal obstruction surgery to perform gastrointestinal decompression and drain the digestive fluid from the gastrointestinal tract. In order to facilitate the fixation of the gastric tube, a drainage catheter such as application number CN201721686952.9 is currently disclosed, which is fixed after being inflated by a ring-shaped inflatable balloon.

[0004] However, it should be noted that after intestinal obstruction surgery, due to large-scale intestinal separation or inflammation in the abdominal cavity, it is easy to cause intestinal wall edema. The annular inflatable balloon of this type of fixed drainage catheter will adhere to the intestinal wall after inflation, and the annular balloon will block the intestinal tract, resulting in the inability to flow the drug when injecting the drug into the intestinal tract. The drainage catheter needs to be removed before injecting the drug, which is cumbersome and affects the patient's recovery.

[0005] Therefore, how to design an adjustable air bag fixed intestinal obstruction catheter that can solve the above technical problems is a technical problem that needs to be solved. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide an adjustable air bag fixed intestinal obstruction catheter to solve the problem that after the existing fixed drainage tube is fixed in the intestinal wall, it is difficult to inject the medicine solution, the operation of injecting the medicine solution is cumbersome, and the recovery efficiency of edema in the patient's intestinal wall is slow.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical solution: comprising a drainage tube, a plurality of annular inflatable airbags arranged at equal intervals along the length of the drainage tube, a plurality of storage sleeves respectively arranged corresponding to the positions of the annular inflatable airbags and sleeved outside the annular inflatable airbags, an air inlet branch pipe connected to the outer peripheral wall of one end of the drainage tube, and a limit assembly slidably sleeved on the drainage tube;

[0008] An inflation channel connected to a plurality of annular inflatable air bags is provided in the side wall of the drainage tube along the length direction of the drainage tube, and the top end of the inflation channel is connected to the air inlet branch pipe;

[0009] The medicine storage sleeve includes a connecting outer membrane fixed on the wall of the drainage tube and a connecting inner membrane fixed on the inner wall of the connecting outer membrane; a medicine storage cavity is formed between the outer wall of the connecting inner membrane and the inner wall of the connecting outer membrane; a plurality of overflow holes are evenly distributed on the connecting outer membrane; a medicine injection hole is also opened on the connecting outer membrane, and a removable sealing plug is provided in the medicine injection hole.

[0010] Furthermore, the limiting assembly includes a limiting ring slidably mounted on the drainage tube, a nasal septum fixer hingedly mounted on the outer peripheral wall of the limiting ring, and a connecting plate hingedly mounted on the outer peripheral wall of the limiting ring.

[0011] Furthermore, the connecting plate includes a main plate hingedly connected to the limiting ring and side plates hingedly arranged on both sides of the main plate.

[0012] Furthermore, a barrier film is fixedly provided in each of the overflow holes.

[0013] Furthermore, the barrier film is provided with a virtual sealed edge.

[0014] Furthermore, the outer peripheral wall of the medicine storage sleeve is also covered with a dustproof film on one side.

[0015] The present invention has the following beneficial effects:

[0016] 1- The present invention is provided with an annular inflatable airbag, an inflation channel and an inflation branch, which makes it convenient for medical staff to use an inflation mechanism to inflate the annular inflatable airbag through the inflation branch, so that the annular inflatable airbag is inflated and pressed against the intestinal wall, thereby fixing the use position of the drainage catheter in the intestinal tract and preventing the intestinal tract from moving inward or outward at will.

[0017] 2-The present invention sets a medicine storage sleeve outside the annular inflatable airbag, and squeezes the inner membrane after the annular inflatable airbag is inflated, so that the medicine liquid in the medicine storage cavity is squeezed out through the barrier membrane and overflows outward, and is applied or injected into the intestinal wall, thereby improving the patient's treatment efficiency and accelerating the recovery of the patient's intestinal wall edema.

[0027] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] See also Figure 1-3 As shown, the solution includes a drainage tube 1, a plurality of annular inflatable airbags 2 arranged at equal intervals along the length of the drainage tube 1, a plurality of storage sleeves 3 respectively arranged at positions corresponding to the annular inflatable airbags 2 and sleeved outside the annular inflatable airbags 2, an air inlet branch pipe 4 connected to the outer peripheral wall of one end of the drainage tube 1, and a limit assembly 5 slidably sleeved on the drainage tube 1;

[0029] An inflation channel 11 communicating with a plurality of annular inflatable airbags 2 is provided in the side wall of the drainage tube 1 along the length direction of the drainage tube 1, and the top end of the inflation channel 11 is connected to the air intake branch pipe 4;

[0030] The drug storage sleeve 3 includes a connecting outer membrane 31 fixed to the wall of the drainage tube 1 and a connecting inner membrane 32 fixed to the inner wall of the connecting outer membrane 31. A drug storage cavity 33 is formed between the outer wall of the connecting inner membrane 32 and the inner wall of the connecting outer membrane 31. The connecting outer membrane 31 is evenly distributed with a plurality of overflow holes 311. The connecting outer membrane 31 also has a drug injection hole 312, and a removable sealing plug 3121 is installed in each drug injection hole 312. Optimally, the sealing plug 3121 is I-shaped to prevent it from falling out of the intestinal tube.

[0031] Furthermore, the limiting assembly 5 includes a limiting ring 51 that is slidably mounted on the drainage tube 1, a nasal septum holder 52 hingedly mounted on the outer peripheral wall of the limiting ring 51, and a connecting plate 53 hingedly mounted on the outer peripheral wall of the limiting ring 51. The limiting ring 51 is fixed to the patient's nose via the nasal septum holder 52, or the limiting ring 51 is fixed to the nose or abdomen via the connecting plate 53 in conjunction with adhesive tape. By using the connecting plate 53, the contact area between the adhesive tape and the patient's skin is reduced, thereby minimizing the pain felt by the patient when removing the adhesive tape.

[0032] Furthermore, the connecting plate 53 includes a main plate 531 hingedly connected to the limiting ring 51 and side plates 532 hingedly arranged on both sides of the main plate 531 .

[0033] Furthermore, a barrier film 3111 is fixedly installed in each of the overflow holes 311. Furthermore, a virtual sealing edge 3112 is provided on the barrier film 3111. When there is no external force, the required sealing edge is intact. When subjected to external force, the required sealing edge is broken, allowing the liquid in the drug storage cavity 33 to flow outward through the overflow hole 311.

[0034] Furthermore, the outer peripheral wall of the medicine storage sleeve 3 is also covered with a dustproof film 34 on one side.

[0035] The working principle is roughly as follows:

[0036] Remove the dust-proof film 34, inject the anti-inflammatory drug into the drug storage cavity 33 through the injection hole 312, extend the drainage tube 1 away from the end of the air inlet branch 4 into the patient's body from the patient's nasal cavity or abdominal wound, and inflate each annular inflatable airbag 2 from the inflation channel 11 through an inflation mechanism (such as an air pump, etc.) so that the annular inflatable airbag 2 is inflated and contacts the intestinal wall; when the annular inflatable airbag 2 contacts the intestinal wall, the annular inflatable airbag 2 applies pressure to the connecting inner membrane 32, so that the liquid medicine in the drug storage cavity 33 overflows through the barrier membrane 3111 and contacts the intestinal wall, making it convenient to inject anti-inflammatory drugs and other liquid medicines into the intestinal tract.

[0037] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
