[0002] The jejunal feeding tube is generally used for the method of administering drugs to the jejunum of patients who are unable to eat. By using the jejunal feeding tube, nutrients are directly provided to the inside of the patient's jejunum, enabling the patient's intestine to directly absorb the nutrients, so as to maintain the patient's nutritional intake and ensure a medical means for the patient's survival regulation. Chinese Patent (Publication No.: CN105380806A) discloses a jejunal feeding tube with a water sac, including a main tube 1, and a tube cap 2 is provided at the tail of the main tube 1; a water pipe 3 is arranged along the tube wall on the side of the main tube 1, a water filling joint 4 is provided at the top end of the water pipe 3, a water-fillable balloon 5 is provided at the bottom end of the water pipe 3, and the water-fillable balloon 5 is coated on the outer wall of the head of the main tube 1.

[0003] However, there are some drawbacks in the use of the existing jejunal feeding tubes. For example:

[0004] In order to facilitate the insertion of the existing jejunal feeding tube into the patient's body, a soft tube is generally used. When inserting the soft jejunal feeding tube, the end of the tube is easily pressed against the gastric wall, causing the jejunal feeding tube to easily coil inside the stomach and preventing the feeding tube from entering the jejunum. Therefore, the expected use requirements of the jejunal feeding tube cannot be achieved. Summary of the Invention

[0030] A jejunal feeding tube with a water sac, comprising a nutrient delivery tube 101. One end of the nutrient delivery tube 101 is connected through a quick connector 102 for nutrient delivery, and the quick connector 102 for nutrient delivery is used to quickly connect the nutrient delivery tube 101 to a nutrient storage container. The outer part of the end of the nutrient delivery tube 101 away from the quick connector 102 for nutrient delivery is wrapped with a first water sac 105. On one inner side wall of the nutrient delivery tube 101, a first water delivery pipe 104 is fixedly laid. One end of the first water delivery pipe 104 is connected to the first water sac 105 through connection, and the end of the first water delivery pipe 104 away from the first water sac 105 penetrates through the nutrient delivery tube 101. The end of the first water delivery pipe 104 located outside the nutrient delivery tube 101 is connected through a first water delivery connector 103, and the first water delivery connector 103 is used to deliver liquid into the first water sac 105 through the first water delivery pipe 104. The outer part of one end of the nutrient delivery tube 101 is wrapped with a second water sac 108. The second water sac 108 is arranged on the side of the first water sac 105 close to the first water delivery connector 103. On the other inner side wall of the nutrient delivery tube 101, a second water delivery pipe 107 is fixedly laid. One end of the second water delivery pipe 107 is connected to the second water sac 108 through connection, and the end of the second water delivery pipe 107 away from the second water sac 108 penetrates through the nutrient delivery tube 101. The end of the second water delivery pipe 107 located outside the nutrient delivery tube 101 is connected through a second water delivery connector 106, and the second water delivery connector 106 is used to deliver liquid into the second water sac 108 through the second water delivery pipe 107. Both the first water delivery connector 103 and the second water delivery connector 106 are arranged at one end close to the quick connector 102 for nutrient delivery;

[0031] Wherein, both the first water sac 105 and the second water sac 108 are in a film-like structure attached to the outer part of the nutrient delivery tube 101. After being filled with water, the film-like structure can form a water sac interlayer, and when the film-like structure is in a state without water filling, it can closely adhere to the outer wall of the nutrient delivery tube 101 without increasing the size of the nutrient delivery tube 101;

[0032] Wherein, both the first water delivery connector 103 and the second water delivery connector 106 can be connected to a syringe. During use, the syringe can be used to inject water into the first water sac 105 and the second water sac 108 through the connection with the first water delivery connector 103 and the second water delivery connector 106;

[0033] Wherein, the nutrient delivery tube 101 is made of soft polyurethane material. The pipeline made of this material has a soft texture and a flat surface, and will not cause damage to the inner wall of human organs;

[0034] During use, first insert the end of the nutrient delivery tube 101 with the first water sac 105 into the patient's stomach through the nasal cavity or oral cavity. When the first water sac 105 enters the patient's stomach, use a syringe to inject water into the first water sac 105 through the first water delivery connector 103 and the first water delivery tube 104. At this time, since the first water sac 105 is filled with water, under the action of gravity, the end of the nutrient delivery tube 101 faces downward, which can facilitate the adjustment of the angle of the nutrient delivery tube 101 and make it easier to pass through the pylorus below the stomach. Since there is a certain bending angle at the pylorus below the stomach and the texture of the nutrient delivery tube 101 is soft, the water in the first water sac 105 can be pumped out, and then use a syringe to inject water into the second water sac 108 through the second water delivery connector 106 and the second water delivery tube 107. At this time, after the second water sac 108 is filled with water, it can push the nutrient delivery tube 101 into the bent pylorus under the action of gravity, relying on the gravity of the second water sac 108 to offset the resistance of the nutrient delivery tube 101 in the pylorus, making it easier for the nutrient delivery tube 101 to enter the jejunum; according to the actual situation, more water sacs can be added to the nutrient delivery tube 101, and repeating the above steps can avoid the situation where the nutrient delivery tube 101 is blocked by the inner wall of the jejunum and cannot enter the predetermined position, making the placement process of the nutrient delivery tube 101 more convenient;

[0035] In the present invention, by providing the first water sac 105 and the second water sac 108 at the end of the nutrient delivery tube 101, and laying the first water delivery tube 104 and the second water delivery tube 107 inside the nutrient delivery tube 101, during the process of inserting the nutrient delivery tube 101 into the patient's body, the angle of the nutrient delivery tube 101 can be adjusted by injecting water into the first water sac 105 and the second water sac 108 in sequence, and the gravity of the water sacs is used to accurately place the nutrient delivery tube 101 into the jejunum, avoiding the nutrient delivery tube for jejunum from coiling inside the gastric cavity and achieving the expected placement requirements of the nutrient delivery tube for jejunum.

[0036] Further, a third water sac 203 is wrapped around the outer part of one end of the nutrient delivery tube 101 away from the nutrient delivery quick connector 102. The third water sac 203 is arranged on the side of the second water sac 108 away from the first water sac 105. A third water delivery pipe 202 is laid on the inner wall of the nutrient delivery tube 101. One end of the third water delivery pipe 202 is connected to the third water sac 203 in a penetrating manner. The end of the third water delivery pipe 202 away from the third water sac 203 penetrates through the nutrient delivery tube 101. One end of the third water delivery pipe 202 located outside the nutrient delivery tube 101 is connected to a third water delivery connector 201 in a penetrating manner. The third water delivery connector 201 is used to deliver liquid into the third water sac 203 through the third water delivery pipe 202. The third water delivery connector 201 is arranged at one end close to the nutrient delivery quick connector 102. A water sac valve 204 is arranged at the connection between the third water delivery pipe 202 and the third water delivery connector 201. The water sac valve 204 is used to prevent the water in the third water sac 203 from flowing out through the third water delivery pipe 202;

[0037] Among them, the structure of the third water sac 203 is the same as that of the first water sac 105 and the second water sac 108, and the usage method is the same. However, the third water sac 203 needs to be arranged at the connection between the nutrient delivery tube 101 and the gastric juice extraction tube 403. That is, when the third water sac 203 moves to the pylorus position of the stomach, the end of the nutrient delivery tube 101 has been inserted into a predetermined position in the jejunum. At this time, the third water sac 203 can also play a role in blocking the pylorus, effectively preventing the nutrients in the jejunum from flowing back into the stomach, and can also prevent gastric juice from flowing into the jejunum through the pylorus. At the same time, the gravity generated by the water in the third water sac 203 can also firmly block the third water sac 203 at the pylorus opening to ensure the above functions. Therefore, after injecting water into the third water sac 203 through the third water delivery connector 201 and the third water delivery pipe 202 using a syringe, it is necessary to use the water sac valve 204 to close the third water delivery pipe 202 to avoid the water in the third water sac 203 from flowing out through the third water delivery pipe 202.

[0038] Further, a rubber cap 301 is sleeved on the end of the nutrient delivery tube 101 away from the nutrient delivery quick connector 102. The rubber cap 301 is used to protect the end of the nutrient delivery tube 101. A nutrient outlet 302 is opened on the side of the rubber cap 301. The nutrient outlet 302 is used to discharge nutrients into the jejunum;

[0039] Among them, since the end of the nutrient delivery tube 101 is likely to abut against the inner wall of the human body cavity during the insertion into the jejunum through the human body cavity, it is necessary to set its end to a soft material such as rubber to avoid damaging the inner wall of the human body cavity. In addition, the soft rubber cap 301 is easier to bend, making the insertion of the nutrient delivery tube 101 smoother. However, it is necessary to ensure that the friction coefficient on the surface of the rubber cap 301 is not too large. This can be achieved by improving the processing technology of the rubber cap 301 to make its surface smoother, or by applying a lubricating substance on the surface of the rubber cap 301 to facilitate the insertion of the nutrient delivery tube 101.

[0040] Furthermore, a gastric juice extraction tube 403 is sleeved outside the nutrient delivery tube 101. The nutrient delivery tube 101 is laid on one side inside the gastric juice extraction tube 403. One end of the gastric juice extraction tube 403 is connected through a negative pressure extraction connector 401. The negative pressure extraction connector 401 is used to connect the gastric juice extraction tube 403 to a negative pressure device. A gastric juice extraction valve 402 is provided at the connection between the gastric juice extraction tube 403 and the negative pressure extraction connector 401. The nutrient delivery quick connector 102 is arranged at one end close to the negative pressure extraction connector 401. One end of the nutrient delivery tube 101 connected to the nutrient delivery quick connector 102 penetrates through the side wall of the gastric juice extraction tube 403. The end of the gastric juice extraction tube 403 away from the negative pressure extraction connector 401 is used to extract gastric juice from the patient's stomach.

[0041] Among them, the extraction port of the gastric juice extraction tube 403 is arranged near the third water sac 203. Since the third water sac 203 can block the pylorus, the third water sac 203 must be placed in the gastric juice gathering area at the bottom of the stomach. Setting the extraction port of the gastric juice extraction tube 403 near it can more easily extract the gastric juice secreted by the human body. The function of the third water sac 203 is similar to that of the gravity ball straw.

[0042] Furthermore, the gastric juice extraction valve 402 is a flow regulating valve, and the gastric juice extraction valve 402 can be any one of a ball valve, a gate valve, and a butterfly valve.

[0043] Among them, since a negative pressure needs to be applied inside the gastric juice extraction tube 403, if this negative pressure is too large, it is easy to cause the gastric juice extraction tube 403 to adsorb on the gastric wall or damage the inner wall of human tissues. Therefore, the gastric juice extraction valve 402 is set as a valve that can regulate the flow rate, and the negative pressure suction can be adjusted by using the gastric juice extraction valve 402 to avoid harm to the inner wall of human tissues.

[0044] Further, one end of the gastric juice extraction tube 403 away from the negative pressure extraction connector 401 is connected through a pipe necking 501. The other end of the pipe necking 501 is fixedly connected to the outer wall of the nutrient delivery tube 101. A gastric juice extraction port 502 is formed on the side wall of the pipe necking 501. The gastric juice extraction port 502 is used to extract the gastric juice in the patient's stomach.

[0045] Among them, since the nutrient delivery tube 101 is placed inside the gastric juice extraction tube 403, and the gastric juice extraction tube 403 needs to perform the work of negative pressure extraction of gastric juice, the diameter of the gastric juice extraction tube 403 needs to be larger than that of the nutrient delivery tube 101. Therefore, a pipe necking 501 needs to be provided at the end of the gastric juice extraction tube 403 to connect the two. Moreover, the pipe necking 501 is also beneficial for the transition from thin to thick when inserting the pipe into the human body, avoiding damage to the inner wall of the human body cavity by the end of the gastric juice extraction tube 403.

[0046] Among them, the pipe necking 501 is arranged at a position close to the third water sac 203, which is beneficial for the gastric juice extraction port 502 to extract the gastric juice inside the gastric cavity.

[0047] Further, a pressure regulating tube 602 is laid on the other side inside the gastric juice extraction tube 403. One end of the pressure regulating tube 602 close to the pipe necking 501 is connected through a pressure regulating port 603. The pressure regulating port 603 is arranged through the side wall of the gastric juice extraction tube 403. The pressure regulating tube 602 adjusts the air pressure inside the patient's stomach through the pressure regulating port 603. The other end of the pressure regulating tube 602 away from the pressure regulating port 603 penetrates through the side wall of the gastric juice extraction tube 403. One end of the pressure regulating tube 602 located outside the gastric juice extraction tube 403 is connected through a pressure tube connector 601. The pressure tube connector 601 is used to connect the pressure regulating tube 602 to a pressure regulating device; a pressure regulating valve 700 is installed at the connection between the pressure tube connector 601 and the pressure regulating tube 602. The pressure regulating valve 700 is used to control the movement state of the air flow inside the pressure regulating tube 602.

[0048] Among them, the pressure regulating tube 602 is used to adjust the air pressure balance inside the gastric cavity, avoiding the increase in the air pressure inside the gastric cavity due to the delivery of nutrients into the jejunum or the air pressure generated by the fermentation of food in the intestine. When the air pressure inside the gastric cavity increases, the patient is prone to feel abdominal distension, bringing discomfort to the patient. At the same time, it can also adjust the negative pressure generated in the gastric cavity after the gastric juice extraction tube 403 extracts the gastric juice. When the air pressure inside the gastric cavity decreases, the patient will also feel discomfort. By appropriately delivering air into or extracting air from the gastric cavity through the pressure regulating tube 602, the air pressure balance in the gastric cavity can be ensured, improving the comfort of the patient.

[0049] In summary, during use, first insert the end of the nutrient delivery tube 101 with the first water sac 105 into the patient's stomach through the nasal cavity or oral cavity. When the first water sac 105 enters the patient's stomach, use a syringe to inject water into the first water sac 105 through the first water delivery connector 103 and the first water delivery tube 104. At this time, since the first water sac 105 is filled with water, under the action of gravity, the end of the nutrient delivery tube 101 faces downward, which can facilitate the adjustment of the angle of the nutrient delivery tube 101 and make it easier to pass through the pylorus under the stomach. Since the pylorus under the stomach has a certain bending angle and the texture of the nutrient delivery tube 101 is soft, the water in the first water sac 105 can be pumped out, and then use a syringe to inject water into the second water sac 108 through the second water delivery connector 106 and the second water delivery tube 107. At this time, after the second water sac 108 is filled with water, it can push the nutrient delivery tube 101 into the bent pylorus under the action of gravity, relying on the gravity of the second water sac 108 to offset the resistance of the nutrient delivery tube 101 in the pylorus, making it easier for the nutrient delivery tube 101 to enter the jejunum; according to the actual situation, more water sacs can be added to the nutrient delivery tube 101, and repeating the above steps can avoid the situation where the nutrient delivery tube 101 is blocked by the inner wall of the jejunum and cannot enter the predetermined position, making the placement process of the nutrient delivery tube 101 more convenient;

[0050] In the present invention, by providing the first water sac 105 and the second water sac 108 at the end of the nutrient delivery tube 101, and laying the first water delivery tube 104 and the second water delivery tube 107 inside the nutrient delivery tube 101, during the process of inserting the nutrient delivery tube 101 into the patient's body, the angle of the nutrient delivery tube 101 can be adjusted by injecting water into the first water sac 105 and the second water sac 108 in sequence, and the gravity of the water sacs is used to accurately place the nutrient delivery tube 101 into the jejunum, avoiding the nutrient delivery tube in the jejunum from coiling inside the gastric cavity and achieving the expected placement requirements of the jejunum nutrient tube.
