Description

Spiral Jejunal Nutrition Tube

technical field

The utility model relates to a medical device, which is a structure of a spiral jejunum nutrition tube.

Background technique

The spiral type jejunum nutrition tube comprises a flexible tube body, a liquid filling nozzle and a head, the front end of the head is sealed, and a liquid outlet hole is arranged on the side wall of the head. The spiral jejunal nutrition tube is used for patients who have difficulty in nasal feeding with a gastric tube and the function of the small intestine still exists. The material of the spiral jejunal nutrition tube body is relatively soft, and a guide wire needs to be inserted into the tube body to help when inserting it. However, even if the guide wire is used, the front part of the spiral jejunum nutrition tube is still in the shape of a hook, because the human body's pharynx The shape of the jejunum is relatively complicated, and the spiral jejunum feeding tube is easy to enter other parts of the pharynx but not easy to enter the esophagus, especially in comatose patients, which may easily cause intubation failure.

Contents of the invention

The utility model aims to provide a spiral jejunum nutrition tube with an improved structure, which is applied to patients who have placed a gastric tube, and can improve the success rate of intubation.

This spiral jejunum nutrition tube includes a tube body, a filling nozzle and a head, the filling nozzle is connected to the rear end of the tube body, the head is fixed on the front end of the tube body, the front end of the head is sealed, and the side wall of the head is sealed. There is a liquid outlet hole, there is a first operation hole on the wall of the pipe body close to the head, and there is a second operation hole on the wall of the pipe body 90-100cm away from the head.

When intubating the spiral jejunal nutrition tube with this structure, the guide wire can be inserted into the stomach by using the gastric tube left in the patient's body, and then the spiral jejunum nutrition tube can be inserted into the stomach by means of the two operation holes on the spiral jejunum nutrition tube. Put it on the guide wire, so that the spiral jejunal nutrition tube is inserted into the patient's body along the guide wire, so as to ensure the success of intubation.

Description of drawings

The accompanying drawing is a schematic structural view of the spiral jejunal nutrition tube of the present invention.

Detailed ways

As shown in the figure, this spiral jejunum nutrition tube includes a tube body 1, a liquid filling nozzle 2 and a head 3. The liquid filling nozzle is connected to the rear end of the tube body, the head is fixed on the front end of the tube body, and the front end of the head Sealing, liquid outlet hole 4 is arranged on the side wall of head. There is a first operation hole 5 near the head on the wall of the pipe body 1, and there is a second operation hole 6 on the wall of the pipe body 90-100 cm away from the head.

The specific operation steps for intubating the helical jejunal nutrition tube with this structure are as follows:

1. Cut the gastric tube at the patient's nose;

2. Remove the guide wire cap at the end of the guide wire, insert the front end of the guide wire into the gastric tube in the patient's body, until the length of the guide wire entering the body is slightly shorter than the length of the gastric tube in the body, and the front end of the guide wire enters In the stomach, the length of the guide wire in the patient's body at this time is about 50cm;

3. Pull out the remaining gastric tube from the body along the guide wire, and remove it from the tail end of the guide wire;

4. Insert the tail end of the guide wire into the first operating hole 5 of the spiral jejunum nutrition tube, so that the spiral jejunum nutrition tube fits on the guide wire until the tail end of the guide wire reaches the spiral jejunum At the second operation hole 6 on the nutrition tube, make the tail end of the guide wire stretch out from the second operation hole 6 on the spiral jejunum nutrition tube;

5. Continue to insert the spiral jejunum nutrition tube into the patient's body along the guide wire until it has a sufficient length (about 90cm), and then pull out the guide wire from the spiral jejunum nutrition tube;

6. Use adhesive tape to seal the second operation hole 6 on the spiral jejunum nutrition tube, so that there is no leakage in the second operation hole after sealing, fix the spiral jejunum nutrition tube well, and the operation is completed.

Because the front end of the gastric tube is straight and has a certain hardness, it is easier to insert. Use the gastric tube left in the patient's body to insert the guide wire into the stomach, and then rely on the two spiral jejunal nutrition tubes of the utility model. The operation hole puts the spiral jejunal nutrition tube on the guide wire, and inserts it into the patient's body along the guide wire, so as to ensure the success of intubation, the success rate of insertion can reach 100%, and reduce the complications during the catheterization process.

The length of the spiral jejunal nutrition tube is generally 145cm, and the diameter is 3.3mm. The length of the guide wire is also 145cm, and the diameter is about 1mm. The diameters of the first operation hole 5 and the second operation hole 6 may be 1.2-1.5mm. The length of the head of the spiral jejunum nutrition tube is about 12 mm, and the distance between the first operation hole 5 and the head can be about 5 mm.
