Description

DISPOSABLE KIT FOR NASOINSTINAL NUTRITION

The proposed utility model relates to medicine, namely to surgery.

The modern concept of nutritional therapy in the correction of metabolic disorders in patients with trophic status disorder and the impossibility of a full enteral nutrition consists in the early intraintestinal administration of nutrient mixtures, nutrients and prebiotics. However, the installation of a nutrient probe is associated with certain difficulties.

Known probe 1 (twice the length of the endoscope) for enteral nutrition, introduced through the instrument channel of the endoscope to the desired area, followed by careful extraction of the endoscope. However, there are no sterile, single-use, specially made enteral probes for passing through the instrument channel of the endoscope.

The prototype of the invention is a single-use kit for trans-needle catheterization jejunostomy "Intestofix, manufactured by" B. Braun Melsungen 2 and used for enteral artificial nutrition. However, there are no sterile, industrially manufactured single-use kits for naso-intestinal nutrition, which would allow a patient to quickly and safely establish a system for introducing a nutrient mixture.

In connection with the foregoing, we have developed a disposable set for nasointestinal nutrition.

EFFECT: reduced traumatism, increased safety and simplified insertion of the probe.

The essence of the proposed utility model:

MPCA61 J 15/00

Probe (1). The outer diameter is 2.5 mm, the inner diameter is 1.5 mm, and the length is 2500 mm. Five holes 0.8 mm in diameter are located at the distal end of the probe. The stiffness of the probe is selected in such a way (Bayer polyvinyl chloride) so that it can be passed through the endoscope channel without the use of a mandrel;

Removable adapter with plug (2). Allows you to connect a system for the drip of nutrient mixtures;

Hollow nasal conductor (3). The outer diameter is 4 mm, the inner diameter is 2.5 mm, and the length is 300 mm. Allows you to quickly and without injury to the mucous membrane to bring the proximal end of the probe through the nose;

1500 ml polyethylene container (4) for a nutrient mixture with a dropper without a filter;

Sealed packaging (5). These kit components are packaged and sterilized.

The proposed kit is used as follows:

1. After the endoscope is inserted into the duodenum, an enteral probe is removed from the kit, which is passed through the instrument channel of the endoscope into the initial section of the jejunum;

2. The endoscope is removed by holding the probe in place;

3. The nasal conductor is passed through the nasal passage and removed through the mouth;

4.A proximal end of the probe is carried out along the hollow nasal conductor and then along with the conductor the end of the probe is pulled through the nasal passage;

5. Using an adapter, the probe is connected to a dropper tank for the nutrient mixture;

6. The solution is poured into the container and the infusion begins at the required speed.

the onset of functioning was 13.6 ± 2.8 minutes. The stay of the probe in the gastrointestinal tract was 5.6 ± 3.8 days. No complications were noted during installation and during operation.

Example:

Patient Iksanova, 52 years old, No. 15750, was admitted to the intensive care unit on 4.08.2001 with a diagnosis of Bilateral purulent salpingitis, diffuse purulent-fibrinous peritonitis, multiple interloop abscesses. The severity of the condition on the ARACNE-P scale is 16 points. On the first day, with the help of an endoscope, a probe from the naso-intestinal nutrition kit was installed, and infusion of saline solutions (start mode) in the amount of 1500-2000 ml per day was started. On the second day, signs of intestinal peristalsis appeared. The introduction of nutrient mixtures has begun. The cessation of congestive gastric contents was noted on the 3rd day, the transition to complete enteral tube feeding was made. The patient was in the intensive care unit for 8 days, the probe stayed in the intestinal tract for 6 days. In the future, the condition improved, the patient was discharged with recovery.
