Description

Technical Field

[0001] The utility model relates to the technical field of nutrition supply devices, in particular to an enteral nutrition device. Background Art

[0002] Enteral nutrition refers to a nutritional support method that provides the body with the required energy and various nutrients through the gastrointestinal tract, mainly through nasogastric tubes, nasoduodenal tubes, nasojejunal tubes, percutaneous gastrostomy tubes, etc.

[0003] Referring to the prior art portable enteral nutrition device - CN218853130U, it includes a ring sleeve; a liquid storage bag is arranged in the inner cavity of the ring sleeve, and the liquid storage bag is used to store nutrient solution; a liquid pump is arranged on the outside of the ring sleeve, the inlet of the liquid pump is connected to the liquid storage bag, and the outlet of the liquid pump is connected to an infusion tube, which is used to input nutrient solution into the human body.

[0004] The device uses a liquid pump to extract nutrient solution from a liquid storage bag and then injects it into the human body through an infusion tube. The ring can be worn around the waist for portability. However, the above device does not have the function of flushing the liquid pump, infusion tube, and adjacent connecting catheters. On the one hand, the liquid pump, infusion tube, and catheter are located inside the ring, making replacement difficult. On the other hand, due to cost issues, these components need to be reused multiple times before replacement. However, after the nutrient solution is injected, some nutrient solution will remain in the liquid pump, infusion tube, and catheter. If the residual nutrient solution is not flushed in time, it is easy to breed bacteria, affecting further use. Therefore, it is necessary to flush and clean these components. Utility Model Content

[0005] The utility model aims to provide an enteral nutrition device to solve the problem in the prior art that a liquid pump, an infusion tube and adjacent catheters cannot be flushed and cleaned, resulting in bacterial growth.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] An enteral nutrition device includes a ring sleeve, a liquid storage bag, a liquid pump, a flushing bag and a Y-shaped tube arranged on the ring sleeve, the output end of the liquid pump is connected to an infusion tube, the Y-shaped tube includes a first bifurcated tube, a second bifurcated tube and a main tube, the main tube is connected to the input end of the liquid pump, a connecting tube is connected between the first bifurcated tube and the second bifurcated tube, the first bifurcated tube, the second bifurcated tube and the connecting tube are all provided with valves, the first bifurcated tube is connected to the flushing bag, and the second bifurcated tube is connected to the liquid storage bag.

[0008] The working principle and beneficial effects of this utility model:

[0009] In this solution, the flushing liquid (such as pure water or saline) is injected into the flushing bag, and the nutrient solution is injected into the liquid storage bag. At this time, the valves on the connecting tube and the first bifurcated tube are closed, and the valve on the second bifurcated tube is opened. The liquid pump generates suction, and the nutrient solution in the liquid storage bag is drawn into the main tube through the second bifurcated tube, and then drawn into the liquid pump. The nutrient solution is then input into the human body through the infusion tube.

[0010] When it is necessary to flush these components, the infusion tube is pulled out of the human body, the valve of the second bifurcated tube is closed to prevent the nutrient solution from flowing into the second bifurcated tube, the valves on the first bifurcated tube and the connecting tube are opened, and the liquid pump generates suction. Part of the flushing liquid flows into the main tube through the first bifurcated tube, and part of the flushing liquid flows into the second bifurcated tube through the connecting tube. After flushing the second bifurcated tube, the flushing liquid flows into the main tube again. The collected flushing liquid is discharged after passing through the main tube, the liquid pump and the infusion tube. The flushing liquid flushes the main tube, the liquid pump and the infusion tube, thereby completing the flushing of the residual nutrient solution on the Y-shaped tube, the liquid pump and the infusion tube.

[0011] This solution sets up a Y-shaped tube and a flushing bag. On the one hand, the nutrient solution delivery and flushing work are independent of each other and do not affect each other. On the other hand, the flushing liquid is used to flush the nutrient solution remaining in the second bifurcation tube, main tube, liquid pump and infusion tube, thereby preventing bacteria from breeding in the above components and extending the service life of the above components.

[0012] Furthermore, the ring sleeve is provided with a heating element for heating the liquid storage bag. The heating element, such as a heating wire or a heating strip, generates heat when energized, and utilizes the heat to heat the nutrient solution in the liquid storage bag, thereby increasing the temperature of the nutrient solution and reducing the physiological discomfort caused by the infusion of the nutrient solution into the human body.

[0013] Furthermore, the infusion tube is provided with a one-way valve, which is open in a direction away from the infusion tube. The one-way valve can ensure that the nutrient solution is only transported in a one-way direction toward the human body, thereby preventing the nutrient solution contaminated by the human body from flowing back into the infusion tube.

[0014] Furthermore, the liquid storage bag and the flushing bag are both provided with an injection head, and the injection head is provided with a sealing plug. The flushing liquid or nutrient solution is injected through the injection head and then sealed with the sealing plug.

[0015] Furthermore, the ring sleeve is provided with a zipper, and the liquid storage bag and the flushing bag are detachably arranged in the ring sleeve. This arrangement makes it convenient to disassemble and take out the liquid storage bag and the flushing bag for replacement.

[0016] Furthermore, the first bifurcated tube and the connecting tube are located above the second bifurcated tube. This arrangement can fully utilize gravity so that the flushing liquid automatically flows into the second bifurcated tube through the connecting tube.

[0017] Furthermore, the ring sleeve is provided with a shoulder strap to provide better support. BRIEF DESCRIPTION OF THE DRAWINGS
