Description

Technical Field

[0001] This utility model relates to the field of enteral nutrition tubing technology, and in particular to an automatic flushing device for enteral nutrition tubing. Background Technology

[0002] Enteral nutrition is a nutritional support method that provides the body with the necessary nutrients and other nutrients through the gastrointestinal tract. Its duration depends on factors such as the patient's mental state and gastrointestinal function. There are two routes of enteral nutrition: oral administration and infusion via a catheter. Infusion via a catheter includes nasogastric tube, nasoduodenal tube, nasojejunal tube, and gastrojejunostomy tube.

[0003] Enteral nutrition tubing is used for enteral nutrition, diagnosis, treatment and monitoring of critically ill patients. It is especially suitable for patients who need to undergo gastrointestinal decompression and feeding at the same time, such as patients after esophageal cancer surgery, gastric cancer surgery, pancreatitis, gastric paralysis, gastric emptying disorder, pyloric stenosis, and prone ventilation for pulmonary infection.

[0004] Chinese patent application publication number CN215879103U discloses an automatic flushing device for enteral nutrition tubing. This invention uses an injection device to flush and clean the nutrient solution infusion line when it is blocked, ensuring that no nutrient solution adheres to the inner wall of the line after one flush, thus ensuring the unobstructed flow of the nutrient solution line and facilitating nutrient solution infusion, reducing the workload of medical staff. A control switch can close the nutrient infusion line or the flushing passage to prevent accidental connection between the two lines, which could lead to cross-contamination of nutrient solution. However, in the process of flushing and cleaning the line, the invention directly flushes out water and impurities, but the impurities flow out with the water, making it impossible to collect and process the impurities separately, which is not conducive to the use of the automatic flushing device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an automatic flushing device for enteral nutrition tubing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic flushing device for enteral nutrition tubing includes a nutrition bag, a nutrient infusion line at the bottom of the nutrition bag, a connecting line at one end of the nutrient infusion line, an installation plate fixedly mounted on the surface of the connecting line, an annular groove at the bottom of the installation plate, an annular block slidably mounted on the inner wall of the annular groove, an installation groove at the surface of the annular block, an opening at the inside of the installation plate, an installation column mounted on the inner wall of the opening via a reset mechanism, a connecting column fixedly mounted at the bottom of the installation plate, and a filtering mechanism at one end of the connecting column.

[0008] Preferably, the reset mechanism includes a sliding column slidably mounted on the inner wall of the slot, a movable plate fixedly mounted on one end of the sliding column, a spring fixedly mounted on the inner wall of the slot, one end of the spring and one side of the movable plate being fixedly mounted, and one side of the movable plate and one end of the mounting column being fixedly mounted.

[0009] Preferably, the filtration mechanism includes a cylinder fixedly installed at one end of the connecting column, and a filter plate is fixedly installed on the inner wall of the cylinder.

[0010] Preferably, one end of the connecting pipe is provided with a flushing fluid bag, and the surface of the connecting pipe is provided with a pump body.

[0011] Preferably, a first valve is provided on the surface of the nutrient infusion pipeline, and a second valve is provided on the surface of the connecting pipeline.

[0012] Preferably, the inner wall of the mounting groove and the surface of the mounting column are fitted together, and the surface of the movable plate and the inner wall of the groove are attached together.

[0013] Preferably, the number of connecting posts is four groups, arranged in an array.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When it is necessary to use a nutrition bag to deliver nutrient solution, the installation column is moved by the reset mechanism, so that the installation column leaves the inner wall of the installation groove. This releases the limiting installation of the annular block, and then the annular block, connecting column and cylinder are removed. By connecting the connecting pipeline to the patient's intestinal passage, opening the first valve and closing the second valve, the nutrient solution can be delivered to the inside of the connecting pipeline through the nutrient infusion pipeline, and finally reach the patient's intestine.

[0016] 2. When flushing the connecting pipeline is required, the annular block, connecting column, and cylinder can be positioned by inserting the annular block into the inner wall of the annular groove. The resetting mechanism drives the mounting column to insert into the inner wall of the mounting groove, thereby limiting the installation of the annular block, and then limiting the installation of the connecting column and cylinder. The first valve is closed, the second valve is opened, and the pump body is started to draw out the water inside the flushing liquid bag, thus flushing the connecting pipeline. At the same time, the filtration mechanism filters impurities, making it easy to collect and process them later. The structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figure 1-4 This utility model provides a technical solution: an automatic flushing device for enteral nutrition tubing, comprising a nutrition bag 1, a nutrition infusion tubing 2 at the bottom of the nutrition bag 1, a connecting tubing 3 at one end of the nutrition infusion tubing 2, a flushing fluid bag 4 at one end of the connecting tubing 3, a pump body 5 on the surface of the connecting tubing 3, a first valve 18 on the surface of the nutrition infusion tubing 2, a second valve 19 on the surface of the connecting tubing 3, an installation plate 6 fixedly mounted on the surface of the connecting tubing 3, an annular groove 7 at the bottom of the installation plate 6, an annular block 8 slidably mounted on the inner wall of the annular groove 7, and an installation groove 9 on the surface of the annular block 8. The part has a slot 10, and the inner wall of the slot 10 is equipped with a mounting column 14 through a reset mechanism. The reset mechanism includes a sliding column 11 that is slidably installed on the inner wall of the slot 10. A movable plate 13 is fixedly installed at one end of the sliding column 11. A spring 12 is fixedly installed on the inner wall of the slot 10. One end of the spring 12 is fixedly installed on one side of the movable plate 13. One side of the movable plate 13 is fixedly installed on one end of the mounting column 14, which facilitates the resetting and movement of the mounting column 14. The inner wall of the mounting slot 9 and the surface of the mounting column 14 are matched, and the surface of the movable plate 13 is in contact with the inner wall of the slot 10 to limit the movement of the movable plate 13, making the movement of the movable plate 13 more stable.

[0024] Specifically, a connecting column 15 is fixedly installed at the bottom of the mounting plate 6. A filter mechanism is provided at one end of the connecting column 15. The filter mechanism includes a cylinder 16 fixedly installed at one end of the connecting column 15. A filter plate 17 is fixedly installed on the inner wall of the cylinder 16 to facilitate the filtration of impurities. When the nutrient bag 1 is needed to deliver nutrient solution, the mounting column 14 is moved by the reset mechanism, so that the mounting column 14 leaves the inner wall of the mounting groove 9, thereby releasing the limiting installation of the annular block 8. Then, the annular block 8, the connecting column 15, and the cylinder 16 can be removed. By connecting the connecting pipe 3 to the patient's intestinal passage, opening the first valve 18 and closing the second valve 19, nutrition can be delivered through the nutrient infusion pipe 2. The liquid is delivered into the connecting pipe 3 and eventually reaches the patient's intestine. When the connecting pipe 3 needs to be flushed, the annular block 8, connecting column 15, and cylinder 16 are positioned by inserting the annular block 8 into the inner wall of the annular groove 7. The installation column 14 is inserted into the inner wall of the installation groove 9 by the reset mechanism, which limits the installation of the annular block 8, and then limits the installation of the connecting column 15 and cylinder 16. The first valve 18 is closed and the second valve 19 is opened. The water inside the flushing liquid bag 4 is drawn out by starting the pump body 5, which flushes the connecting pipe 3. At the same time, the impurities are filtered by the filtration mechanism, which facilitates the collection of impurities and facilitates subsequent processing of impurities. The structure is simple and easy to use.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: When using this automatic enteral nutrition tubing flushing device, when it is necessary to use the nutrition bag 1 to deliver nutrient solution, pull the sliding column 11 to move the moving plate 13. The moving plate 13 moves the mounting column 14, causing the mounting column 14 to leave the inner wall of the mounting groove 9. This releases the limiting installation of the annular block 8, allowing the annular block 8, connecting column 15, and cylinder 16 to be removed. By connecting the connecting tubing 3 to the patient's intestinal passage, opening the first valve 18 and closing the second valve 19, the nutrient solution can be delivered to the inside of the connecting tubing 3 through the nutrition infusion tubing 2, ultimately reaching the patient's intestines. When it is necessary to flush the connecting tubing 3, insert the annular block 8... The ring block 8, connecting column 15, and cylinder 16 are positioned by inserting the ring 12 into the inner wall of the annular groove 7. The spring 12 resets and moves the moving plate 13, which in turn moves the mounting column 14, allowing the mounting column 14 to insert into the inner wall of the mounting groove 9. This limits the installation of the annular block 8, and consequently limits the installation of the connecting column 15 and cylinder 16. The first valve 18 is closed, and the second valve 19 is opened. The pump body 5 is started to draw out the water inside the flushing liquid bag 4, which flushes the connecting pipeline 3. At the same time, the filter plate 17 blocks the impurities, leaving them inside the cylinder 16 for easy collection and subsequent processing. The structure is simple and easy to use.
