Ultrasonic guidance pernasal implantation dual-chamber nasogastric tube and nasal jejunal feeding tube composite conduit

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to an ultrasonic guidance pernasal implantation dual-chamber nasogastric tube and nasal jejunal feeding tube composite conduit. The composite conduit comprises a conducting wire body (1), a conducting wire handle (2), an injection hole (3), a connecting tube (4), a nasal jejunal feeding tube body (5), a tail end connecting body (6), a hook body (7), a liquid sac (8), a sealing tube (9), a nasogastric tube (10), a tee joint (11), a main tube (12), a side tube (13), side holes and a tube cap. The composite conduit is characterized in that one end of the tee joint (11) is a first inlet, the other end of the tee joint (11) is an outlet, a second inlet is formed in one side, the main tube (12) isinstalled in the first inlet of the tee joint (11) in a matched mode, the nasogastric tube (10) is installed in the outlet of the tee joint (11) in a matched mode, the side tube (13) is installed in the second inlet of the tee joint (11) in a matched mode, and the side holes are formed in the two sides of one end of the nasogastric tube (10) respectively.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ultrasound-guided double-cavity nasogastric tube nasojejunal tube composite catheter inserted through the nose. Background technique [0002] Modern nutrition theory and practice attaches great importance to the special role of enteral nutrition (EN) in nutritional support treatment, maintenance of intestinal mucosal barrier, intestinal motility and secretion function, which has attracted the attention of clinicians. The guidelines and consensus further support early enteral nutrition (EEN), which believes that in addition to providing nutritional support, EEN can also prevent infection and metabolic complications, reduce the permeability of the intestinal mucosa, prevent bacterial translocation and endotoxin exposure. Use the intestines as soon as possible, which can improve the nutritional status and immunity of the patient, reduce complications, and reduce clinical ...

Problems solved by technology

However, in this method, patients need to receive gastroscopic diagnosis and treatment, which requires high equipment and technology, and it is difficult to promote

[0007] 3. Electromagnetic positioning navigator guides down-going nasojejunal tube insertion technology. The method is to insert a guide wire or nutrition tube with an electromagnetic transmitter from the nasal cavity through the stomach and duodenum under the monitoring of the electromagnetic positioning navigator at the bedside. , placed in the distal end of the Treitz ligament, and then a bedside plain film of the abdomen was performed to confirm the position of the nutrition tube.

[0008] 4. X-ray-guided catheterization, the method is to insert the nostril enteral nutrition tube into the upper part of the jejunum distal to the Treitz ligament by using a super-smooth guide wire and contrast catheter under the guidance of X-rays. The effect is reliable, but the disadvantage is that there are radiation and equipment venue restrictions

Ultrasound-guided naso-intestinal tube implantation was reported at the 2016 National Intensive Care Medicine Conference, which is a current method with low equipment investment (bedside ultrasound is popular in most hospitals), no site restrictions, high technical feasibility, and good results. At the same time, it has the advantages of less invasive operation and no radiation. It is the most popular method known so far. However, the existing technology has the practical problems of difficulty in developing the catheter in the gastrointestinal cavity and difficult identification of the catheter in the image.
