Description

Disposable enteral nutrition infusion device

Technical Field

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

Background technique

Enteral nutrition is a nutritional support method that provides nutrients required for metabolism and various other nutrients through the gastrointestinal tract. It is mainly infused through nasogastric tubes, nasoduodenal tubes, nasojejunal tubes and gastrojejunostomy tubes in clinical practice. It is widely used in patients in general surgery, neurosurgery, critical care medicine, geriatrics, etc. At present, clinical practice mainly involves pouring enteral nutrition liquid into a special enteral nutrition bag, and injecting nutrients into the patient's body with an enteral nutrition infusion pump or by gravity infusion.

The above method mainly has the following problems: 1. The opening of the enteral nutrition bag currently used is a buckle type and cannot be completely closed. For example, when the enteral nutrition bag needs to be removed during the patient's transfer, it is easy to spill and leak, resulting in waste of enteral nutrition liquid, contamination of the patient's bed unit, and increased workload of nurses; 2. There is no eye-catching mark on the enteral nutrition bag currently used to remind nurses that this liquid is used by a "non-intravenous" route, and there is a possibility of accidental intravenous infusion. Nurses need to re-make the label and mark the time when the liquid starts to be infused to prevent the enteral nutrition bag from being used for more than 24 hours; 3. The enteral nutrition bag currently used is designed with a material similar to a soft plastic bag. Although the scale is marked, due to the deformability of the liquid, in the actual use process, the nurse cannot accurately grasp the amount of enteral nutrition solution the patient has received and the amount of enteral nutrition solution remaining to be infused, which increases the difficulty of nursing; 4. The enteral nutrition bag currently used does not have a special place for nurses to hold so that the nurses can stabilize it. , conveniently pouring in enteral nutrition liquid; 5. The bottom of the enteral nutrition bag currently in use has no support, which is convenient for pouring in enteral nutrition liquid and storing it when not in use; 6. The Y-shaped bifurcation of the enteral nutrition bag currently in use has an independent cap, which is small in size. When the nurse injects the medicine, it needs to be removed and placed in a special place, which is easy to fall and increase the workload of the nurse; 7. When the patient stops injecting enteral nutrition liquid and needs to separate the enteral nutrition bag and the nasogastric tube and other pipelines, there is no special instrument position to place the pagoda joint of the enteral nutrition infusion device. Nurses often need to find gauze and rubber bands to wrap it, which wastes time and is easy to contaminate; 8. When it is necessary to connect or separate the enteral nutrition bag and the nasogastric tube and other pipelines, the enteral nutrition bag currently in use adopts a double-wing T-shaped design near the pagoda joint of the enteral nutrition bag, with a small contact area. It is often difficult for nurses to unscrew it easily and need to use tools, which is not easy to operate.
