[0030] Referring to Figure 1 and Figure 2 As shown, a digestive juice isolation catheter member 100 for intestinal indwelling according to an embodiment of the present utility model can be used in the intestinal tube 200 of the human body to isolate the intestinal tube 200 with a fistula. The intestinal tube 200 can be the duodenum. It should be noted that the end of the intestinal tube 200 close to the stomach 220 is the proximal end, and the end close to the large intestine is the distal end. The digestive juice isolation catheter member 100 for intestinal indwelling according to the embodiment of the present utility model includes: a diversion tube 110, a first expansion body 120, a second expansion body 130, and an adsorbent 140. One end of the diversion tube 110 is an outlet end 114, and the other end is an inlet end 115. A first channel 111 and a second channel 112 are provided in the diversion tube 110. One end of the first channel 111 communicates with the outlet end 114, and the other end can communicate with the outlet end 114. Both the first expansion body 120 and the second expansion body 130 are connected to the side wall of the diversion tube 110. The inner cavities of the first expansion body 120 and the second expansion body 130 both communicate with the second channel 112, and the first expansion body 120 and the second expansion body 130 are configured to be inflated or filled with water through the second channel 112, so that the first expansion body 120 and the second expansion body 130 expand and become larger. The adsorbent 140 is connected to the side wall of the diversion tube 110 and is located between the first expansion body 120 and the second expansion body 130. The adsorbent 140 is configured to be able to adsorb digestive juice.

[0031] Referring to Figure 1 As shown, when the digestive juice isolation catheter member 100 for intestinal indwelling is arranged in the intestinal tube 200, the inlet end 115 of the diversion tube 110 is located inside the intestinal tube 200, and the outlet end 114 is located outside the human body. Referring to Figure 2As shown, the first inflatable body 120 and the second inflatable body 130 are respectively located at both ends of the fistula 210. For example, the first inflatable body 120 is located at the distal end of the intestinal tube 200, and the second inflatable body 130 is located at the proximal end of the intestinal tube 200. Then, water or gas is filled into the first inflatable body 120 and the second inflatable body 130 through the second channel 112, so that the first inflatable body 120 and the second inflatable body 130 expand to block both ends of the fistula 210, thereby reducing the direct contact of digestive juice with the fistula 210. Since the first channel 111 communicates with the outlet end 114, the patient can supplement the required nutrition in the form of liquid diet. The liquid diet is poured into the first channel 111, passes through the first inflatable body 120 and the second inflatable body 130 in the first channel 111, and then enters the distal end of the intestinal tube 200 from the outlet end 114, thus avoiding the contact of liquid food with the fistula 210. The adsorbing member 140 is located at the fistula 210. The adsorbing member 140 can adsorb the digestive juice generated by the intestinal tube 200 between the first inflatable body 120 and the second inflatable body 130, or adsorb the digestive juice infiltrating from other positions, etc., so as to reduce the corrosion of the fistula 210 by the digestive juice, prevent anastomotic leakage, promote the healing of the fistula 210, and improve the cure rate.

[0032] In order to avoid the situation that when filling water or gas, the pressure in the first inflatable body 120 and the second inflatable body 130 is too high, resulting in damage, or squeezing the intestinal tube 200, or the pressure is too low and there is not enough pressure to isolate digestive juice. Refer to Figure 1 As shown, in the embodiment of the present utility model, a pressure gauge 150 is provided at the inlet end 115. The pressure gauge 150 is located at the inlet of the second channel 112 and is configured to detect the pressure in the second channel 112. For example, the pressure gauge 150 is a simple pressure gauge for detecting water pressure or air pressure, and a suitable pressure gauge 150 is selected specifically according to whether it is filling gas or water. By judging the magnitude of the pressure, it can be determined whether the first inflatable body 120 and the second inflatable body 130 are inflated in place, which can improve the safety and reliability of use.

[0033] Refer to Figure 2As shown, in the embodiment of the present utility model, the diversion tube 110 is further provided with a third channel 113, and the third channel 113 communicates with the inlet end 115. A first opening 1171 is provided on the side wall of the diversion tube 110 between the first expansion body 120 and the second expansion body 130. The first opening 1171 communicates with the third channel 113, and the adsorbent 140 covers the first opening 1171. The inlet end 115 of the diversion tube 110 is provided with three connectors, and each connector respectively corresponds to and communicates with the first channel 111, the second channel 112, and the third channel 113. The digestive fluid isolation catheter component 100 for indwelling in the intestine further includes a negative pressure component, and the negative pressure component is connected to the connector communicating with the third channel 113. It can be understood that the adsorption capacity of the adsorbent 140 is easily saturated, and after saturation, the adsorbent 140 will fail. Therefore, by setting the negative pressure component, a negative pressure is generated in the third channel 113, and then the digestive fluid adsorbed by the adsorbent 140 can be discharged through the third channel 113, so as to ensure that the adsorbent 140 can continuously function, improve the reliability of the adsorbent 140, and avoid the situation of frequent replacement.

[0034] In the embodiment of the present utility model, the adsorbent 140 can be a sponge. Due to its porous structure, the sponge has excellent adsorption ability and can quickly absorb and store a large amount of digestive fluid to reduce the infection of the digestive fluid to the fistula opening 210. At the same time, medical sponges are usually made of materials that are harmless and non-irritating to the human body. These materials will not cause allergic reactions or rejection reactions when used inside the human body, which is beneficial to the healing and recovery of the fistula opening 210. Moreover, the sponge is soft and easy to shape, and can easily adapt to various shapes and sizes of the fistula opening 210 or the area where digestive fluid needs to be absorbed. This enables the sponge to closely fit the surface of the fistula opening 210 and effectively absorb and reduce the leakage of digestive fluid.

[0035] Refer to Figure 3 As shown, in the embodiment of the present utility model, the diversion tube 110 includes a tube body 117, a first partition 118, and a second partition 119. The first partition 118 is provided inside the tube body 117, and both side edges of the first partition 118 are connected to the inner wall of the tube body 117. A first channel 111 is formed between one side of the first partition 118 and the inner wall of the tube body 117. The two side edges of the second partition 119 are respectively connected to the other side of the first partition 118 and the inner wall of the tube body 117 to respectively form a second channel 112 and a third channel 113. With the above solution, the first channel 111, the second channel 112, and the third channel 113 are mutually separated and do not interfere with each other, and the structure of the diversion tube 110 is compact and occupies a small space. In another embodiment, it can also be a way of arranging three pipelines inside the diversion tube 110 to respectively form the first channel 111, the second channel 112, and the third channel 113, and a suitable solution is specifically selected according to the actual situation.

[0036] To avoid the accumulation of digestive fluid at the upper end of the second inflatable body 130, refer to Figure 2 As shown, in the embodiment of the present utility model, the first inflatable body 120 is located on one side of the diversion tube 110 close to the outlet end 114, and the second inflatable body 130 is located on the side of the diversion tube 110 away from the outlet end 114. The side wall of the diversion tube 110 is provided with a second opening 1172 communicating with the first channel 111, and the second opening 1172 is located on the side of the second inflatable body 130 facing away from the adsorbent 140. Therefore, the digestive fluid generated by the stomach 220 and the intestinal tube 200 can enter the first channel 111 through the second opening 1172, and then enter the distal end of the intestinal tube 200 from the outlet end 114 of the diversion tube 110, effectively reducing the accumulation of digestive fluid.

[0037] Refer to Figure 2 As shown, in the embodiment of the present utility model, the shortest distance between the second opening 1172 and the second inflatable body 130 is L, satisfying 0mm ≤ L ≤ 20mm. It can be understood that when L is less than 0mm, that is, when the second opening 1172 is covered by the second inflatable body 130, it is difficult to play a role in drainage; when L is greater than 20mm, that is, when the distance between the second opening 1172 and the second inflatable body 130 is too far, it is easy to cause the accumulation of digestive fluid in the intestinal segment between the second opening 1172 and the second inflatable body 130. Therefore, reasonably designing the size of L can effectively reduce the accumulation of digestive fluid at the upper end of the second inflatable body 130 and improve the patient's use experience.

[0038] In the embodiment of the present utility model, the first inflatable body 120 and the second inflatable body 130 are water sacs. The water sacs can adapt to the shape of the intestinal tube 200, closely fit the intestinal wall, and form an effective barrier, thereby greatly reducing the leakage of digestive fluid or food residues. And the water sacs are usually made of medical-grade materials and have good biocompatibility, and will not cause irritation or damage to the intestine. In another embodiment, the first inflatable body 120 and the second inflatable body 130 are air sacs, and the effects are similar to those of the water sacs, which will not be elaborated here.

[0039] In the embodiment of the present utility model, a water pump is provided at the outlet end 114 of the diversion tube 110, and the water pump is connected to a joint communicating with the second channel 112. Water is pumped to the water sac through the water pump, so that the water sac can expand to block both ends of the fistula 210. When it is confirmed that the fistula 210 has healed, the water in the water sac can also be pumped out by the water pump, and the volumes of the first inflatable body 120 and the second inflatable body 130 are reduced, so as to facilitate the extraction of the digestive fluid isolation catheter 100 for indwelling in the intestine from the intestinal tube 200.

[0040] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
