Description

A self-propelled disposable jejunal tube

technical field

The invention relates to the technical field of medical devices, in particular to a self-propelled disposable jejunal tube.

Background technique

Some patients cannot eat on their own after gastric surgery, or some young children have digestive tract problems and lack the ability to eat on their own. At this time, they need to use a feeding tube to deliver food or milk directly to the stomach. However, due to the peristalsis of the stomach and other reasons, feeding food or milk directly into the stomach through a feeding tube will cause reflux. Therefore, most people choose to use a jejunal tube to put it into the duodenum, so that the food or milk can be directly delivered to ten The duodenum thus avoids reflux.

In the prior art, the placement of the jejunal tube into the duodenum is usually assisted by instruments. One is to let the patient lie down under X-rays and observe the position of the jejunal tube with the aid of X-rays, so that the jejunal tube can be smoothly inserted into the duodenum. This method is very expensive; another method is to use a gastroscope to complete the operation of inserting a jejunal tube into the duodenum with the aid of a gastroscope, but this method is very uncomfortable for patients, and some patients (especially young children) The esophagus is too narrow for the endoscope to enter the esophagus.

SUMMARY OF THE INVENTION

In order to solve the shortcomings of the above technologies, the present invention provides a self-propelled disposable jejunal tube.

In order to solve the above technical problems, the technical solution adopted in the present invention is: a self-propelled disposable jejunal tube, comprising a jejunal lumen, a No. 1 tube head and a No. 2 tube head, a balloon is arranged on the jejunum lumen, and the No. 1 tube is provided with a balloon. The head and the No. 2 tube head are connected in a Y-shape, the No. 1 tube head is provided with a nutrition lumen, the nutrition lumen is placed inside the jejunum lumen, a guide wire is placed in the nutrition lumen, and the lower part of the nutrition lumen is opened. There is a nutrition port running through the nutrition lumen and the jejunum lumen;

The No. 2 pipe head is provided with a water injection lumen, and the water injection lumen is placed inside the jejunum lumen; the top of the No. 2 pipe head is connected with a No. 1 syringe, and the top of the No. 1 pipe head is connected with a No. 2 syringe.

Further, the No. 1 pipe head is sleeved with a No. 1 pipe cover that matches the No. 1 pipe head.

Further, the balloon is located at the lower part or bottom of the jejunum lumen, and the balloon contains water or air or contrast agent.

Further, the top end of the nutrient lumen is communicated with the No. 1 tube head, and the bottom end thereof reaches the bottom of the jejunum lumen or the top of the balloon.

Further, the guide wire is a steel wire or a nylon guide wire.

Further, the top end of the water injection lumen is communicated with the No. 2 tube head, and the bottom end thereof reaches the lower part of the jejunum lumen 1 and communicates with the inner cavity of the balloon.

Further, the opening of the No. 2 pipe head is provided with a pipe plug that matches it.

Further, the nutrition port includes one or more.

The beneficial effects of the present invention are: when the present invention is in use, only the jejunal tube needs to be inserted into the stomach from the nasal cavity or the oral cavity. Under the action of peristalsis, with the peristalsis of the stomach, it will be delivered to the duodenum after 24 hours, without the help of artificial instruments, so that food or milk can be directly delivered to the duodenum to avoid reflux, and nutrition The lumen can deliver nutrients and, if necessary, suck out food/milk residues in the stomach.

The invention solves the existing clinical problems, does not require the patient to spend a lot of money for X-ray operation, and also solves the problem that the esophagus of the patient (especially young children) is too narrow for gastroscopic operation, and is convenient to use and easy to popularize.

Detailed ways

The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

The self-propelled disposable jejunal tube shown in FIG. 1-3 includes a jejunal lumen 1, a No. 1 tube head 2 and a No. 2 tube head 3. The jejunal lumen 1 is provided with a balloon 6, and the balloon 6 is located in the jejunal lumen 1. The lower part or bottom of the balloon can be injected with water or air or contrast agent. The No. 1 tube head 2 is sleeved with a No. 1 tube cover 11 that matches it. The No. 1 tube head 2 and the No. 2 tube head 3 are Y No. 1 tube head 2 is provided with a nutrition lumen 4, the nutrition lumen 4 is placed inside the jejunum lumen 1, its top is communicated with the No. 1 tube head 2, and its bottom end directly reaches the bottom of the jejunum lumen 1 Or on the top of the balloon 6, a guide wire 5 is placed in the nutrition lumen 4. The guide wire 5 is a steel wire or a nylon guide wire. The guide wire 5 increases the weight of the jejunal lumen 1, which is more conducive to the downward entry of the jejunal tube In the duodenum, a nutrition port 8 extending through the nutrition lumen 4 and the jejunum lumen 1 is opened in the lower part of the nutrition lumen 4, the nutrition port 8 includes one or more, and the nutrition port 8 is used for milk and food from nutrition.
