technical field

The utility model relates to the technical field of medical devices, in particular to a disposable portable enteral nutrition input device.

Background technique

In Children's Hospital, an enteral nutrition method is used to provide children with daily needs for children who cannot eat independently after gastrointestinal surgery. Enteral nutrition is input through indwelling nasogastric tube or nasojejunal feeding tube. For large doses of nutrients, we will use disposable enteral nutrition supply line devices. At present, enteral nutrition in hospitals usually uses 100 peptides, homogenates, etc. There are often cases where 100 peptides cannot be completely dissolved, and the homogenate cannot be completely broken. The disposable enteral nutrition supply pipeline we use does not Without a filter device, the nasogastric tube or nasojejunal feeding pipeline will be blocked. Even if the tube is flushed with warm water immediately and enters the child’s gastrointestinal tract, it will also cause adverse reactions such as diarrhea and abdominal pain in the child.

The Chinese utility model patent with the announcement number CN204932308U discloses a disposable enteral nutrition supply pipeline, which has the following drawbacks: before the nutrition agent is delivered to the nasogastric tube or the nasojejunum of the child, the dissolved oligopeptide cannot be Or the homogenate residue is filtered, so that the pipeline is blocked.

The sealing mechanism It consists of a sealing seat with a hanging strip and a sealing plug. The sealing seat is placed at the input end of the nutrient solution bag. The sealing plug and the sealing seat are connected and fixed by a connecting rubber strip, and the sealing plug is placed inside the sealing seat. An iron ring is installed in the middle of the seat through the hanging ear, the outer wall of the iron ring is wrapped with a gauze bag, and the gauze bag is located in the sealing seat.

Preferably, a through hole is opened in the middle of the sealing seat, and a convex plug block is provided on the middle side of the sealing plug, the plug block is adapted to the through hole, and the gauze bag is placed in the through hole Inside.

Preferably, the iron ring is circular, and the diameter of the through hole is equal to the diameter of the iron ring.

Preferably, the hanging lugs are symmetrically distributed on both sides of the iron ring, and the hanging lugs and the iron ring are fixed by hinged connection.

Preferably, the angle through which the hanging lug and the sealing seat are clamped is 90°.

Compared with the prior art, in the present invention, a sealing mechanism is arranged at the entrance of the nutrient solution bag, and an iron ring with a gauze bag is arranged through the hanging ear in the sealing mechanism, so that the nutrient solution is delivered to the nasogastric area of the child before it is delivered. Before the tube or nasojejunum, the dissolved small peptide or homogenate residue can be filtered, so as to avoid the problem of tube blockage.
