Description

Technical Field

[0001] This utility model belongs to the field of jejunal feeding tube technology, specifically relating to a jejunal feeding tube that can be subjected to negative pressure suction. Background Technology

[0002] A jejunal feeding tube is a medical device inserted surgically or percutaneously endoscopically, primarily for patients requiring long-term or short-term enteral nutritional support. It is inserted into the jejunum, the part of the small intestine that passes through the stomach, rather than directly into the stomach like a traditional gastric tube. The main purpose of a jejunal feeding tube is to provide enteral nutrition, that is, to deliver liquid nutrients directly into the small intestine through this tube, rather than through the mouth or stomach. This method is often used for people who cannot eat normally or for patients who require direct intestinal absorption of nutrients due to digestive and absorptive problems. In some cases, especially when precise control of the feeding rate is needed, a pump device may be required. This device uses a pump to precisely deliver the nutrient solution into the jejunum.

[0003] When delivering viscous nutrient solutions or medications, blockages may occur inside the tube, and traditional jejunal feeding tubes cannot handle such blockages.

[0004] To address these issues, those skilled in the art have proposed a negative pressure suction jejunal feeding tube to solve the problems raised in the background art.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a jejunal feeding tube that can be used for negative pressure suction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A negative pressure suction jejunal feeding tube, comprising:

[0009] The conveying mechanism includes a main pipeline and a branch pipe connected to the periphery of the main pipeline. The branch pipe is connected to the interior of the main pipeline. A regulating ball valve is installed at one end of the branch pipe, and a nutrient solution conveying pipe is connected to the end of the regulating ball valve away from the branch pipe.

[0010] The drainage mechanism includes a negative pressure ball connected to one end of a main pipe, a drainage bag connected to the other end of the main pipe, the drainage bag being connected to the negative pressure ball through the main pipe, a connecting tube being provided at the end of the negative pressure ball away from the main pipe, and a jejunal feeding tube being connected to one end of the connecting tube.

[0011] Preferably, a delivery pump is installed at the end of the nutrient solution delivery pipe away from the regulating ball valve, and a nutrient solution inlet is provided at the end of the delivery pump away from the nutrient solution delivery pipe, and the nutrient solution inlet is connected to the nutrient solution delivery pipe.

[0012] Preferably, a clamp is provided on the circumferential side of the main pipe, and the clamp is located between the branch pipe and the drainage bag.

[0013] Preferably, the upper surface of the drainage bag is provided with a detachable threaded interface, and one end of the main pipe is provided with a second threaded connection end, and the detachable threaded interface is screwed to the second threaded connection end.

[0014] Preferably, one end of the connecting tube is provided with a first threaded connection end, and one end of the jejunal feeding tube is provided with a connecting threaded opening, and the first threaded connection end is screwed into the connecting threaded opening.

[0015] Preferably, a drain valve is provided on the lower surface of the drainage bag, an air tube is connected to the negative pressure ball, and a piston is provided at one end of the air tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model is equipped with a nutrient solution delivery pipe, a negative pressure ball and a drainage bag. During normal use, the main pipe can be clamped with a clamp to keep the drainage bag in a sealed state. At this time, the regulating ball valve is open and the delivery pump can be used to deliver the nutrient solution normally. When the jejunal feeding tube is blocked, the clamp can be removed and the regulating ball valve can be closed. At this time, the negative pressure ball can be pressed to form a negative pressure inside, so that the foreign matter accumulated in the jejunal feeding tube can be adsorbed. The adsorbed foreign matter will flow into the drainage bag along the main pipe.

[0018] (2) This utility model has a gas tube with a piston on the drainage bag. The piston can be pulled out to access the negative pressure state. At the same time, the liquid discharge valve is used to discharge the collected waste liquid. Furthermore, the drainage bag and jejunal feeding tube of this device are threaded connections, which makes it easy to disassemble and clean them.

[0027] Please see Figures 1-4 As shown, a negative pressure suction jejunal feeding tube includes:

[0028] The conveying mechanism includes a main pipe 11 and a branch pipe 15 connected to the periphery of the main pipe 11. The branch pipe 15 is connected to the inside of the main pipe 11. A regulating ball valve 14 is installed at one end of the branch pipe 15, and a nutrient solution conveying pipe 1 is connected to the end of the regulating ball valve 14 away from the branch pipe 15.

[0029] The drainage mechanism includes a negative pressure ball 9 connected to one end of the main pipe 11, and a drainage bag 7 connected to the other end of the main pipe 11. The drainage bag 7 is connected to the negative pressure ball 9 through the main pipe 11. A connecting pipe 4 is provided at the end of the negative pressure ball 9 away from the main pipe 11, and a jejunal feeding tube 2 is connected to one end of the connecting pipe 4.

[0031] Specifically, clamps 6 are installed on the side of the main pipe 11, and clamps 6 are located between the branch pipe 15 and the drainage bag 7.

[0032] As can be seen from the above, this device, by setting up a nutrient solution delivery tube 1, a negative pressure ball 9, and a drainage bag 7, allows the main pipe 11 to be clamped with clamps 6 during normal use, so that the drainage bag 7 is in a sealed state. At this time, the regulating ball valve 14 is in the open state, and the delivery pump 12 can be used to deliver the nutrient solution normally. When stagnation and blockage occur in the jejunal feeding tube 2, clamps 6 can be removed and the regulating ball valve 14 can be closed. At this time, the negative pressure ball 9 can be pressed to create a negative pressure inside, thereby adsorbing the foreign matter accumulated in the jejunal feeding tube 2. The adsorbed foreign matter will flow into the drainage bag 7 along the main pipe 11.
