Description

Novel AB type nose intestine tube

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a novel AB type nasointestinal tube.

Background

In critically ill patients, early enteral nutrition intervention is required, which requires manual catheterization to establish a tube feeding pathway. When a critically ill patient establishes an artificial airway for mechanical ventilation, high reflux and high aspiration risks exist, so that a catheter is usually kept in the jejunum for the critically ill patient clinically so as to reduce the incidence rate of feeding-related complications. Although nasojejunal intubation is the first choice for early enteral nutrition intervention of critical patients, the establishment of the tube feeding route has many problems in clinical practice, and the progress of early enteral nutrition is limited. At present, the methods for clinically indwelling the nasointestinal tube include a blind insertion method, a passive waiting method, a liquid sac jejunum catheter tube placing method, a nasal intestinal tube placed in an operation, a nasointestinal tube placed under the guidance of an endoscope, a nasointestinal tube placed under X-ray fluoroscopy and the like, wherein the blind insertion method is the most common method. The success rate of the blind insertion method varies from person to person, and the stability of successful tube placement is poor. In the process of placing the tube in the naso-intestinal tube, the tube is difficult to place due to the existence of the throat part from the nasal cavity to the esophagus, and meanwhile, the tube is difficult to place in the jejunum tube when passing through the pylorus.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provides a novel AB type nasointestinal tube.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a novel AB formula nose intestines pipe, establishes the outer tube and the inner tube of laminating including overlapping each other, and the inner wall of outer tube and the outer wall of inner tube all are equipped with the lubricant film.

One end of the outer tube and one end of the inner tube are bullet structures.

The outer tube is provided with an air bag, and the air bag is arranged at one side close to the bullet head.

The outer pipe and the inner pipe are both composed of two semicircular sheets which are bonded into a tubular body through bonding layers.

The inner diameter of the outer pipe is 3mm, the inner diameter of the inner pipe is 2mm, and the lengths of the outer pipe and the inner pipe are 130 cm.

The utility model has the beneficial effects that: the nasal and intestinal tubes sleeved with the AB type can assist the inner tube or the outer tube to be placed into the jejunum, so that the nasal and intestinal tube is easier to guide in, does not damage mucosa, and has high success rate.

In the figure: outer tube 1, inner tube 2, lubricating layer 3, gasbag 4, adhesive layer 5.

Detailed Description

The utility model is further described with reference to the accompanying drawings and the detailed description below:

as shown in fig. 1 ~ 4 a novel AB type nose intestines pipe, establish outer tube 1 and inner tube 2 of laminating including overlapping each other, the inner wall of outer tube 1 and the outer wall of inner tube 2 all are equipped with lubricating layer 3, make things convenient for two pipe to overlap each other and establish, when using, earlier put into the esophagus with outer tube 1, when the follow-up will be changed, only need embolia outer tube 1 with inner tube 2 in, can change after taking original outer tube 1 out, follow-up 1 cover of outer tube outside inner tube 2, relapse above-mentioned operation and can replace empty intestines pipe many times, and convenient for operation, it is more leading-in easily, can not cause the damage to the mucosa again, and the success rate is high.

One end of the outer tube 1 and one end of the inner tube 2 are of bullet head structures, so that the front ends of the outer tube 1 and the inner tube 2 can play a guiding role conveniently, and damage to mucosa is reduced.

Be equipped with gasbag 4 on the outer tube 1, gasbag 4 is close to one side setting of bullet head, has certain physiological curvature in nasal cavity to esophagus position, and when outer tube 1 put into, gasbag 4 carries out certain expansion to this position, makes things convenient for the pipeline to pass this position.

The outer pipe 1 and the inner pipe 2 are both composed of two semicircular sheets, the two semicircular sheets are bonded into a tubular body through a bonding layer 5, the bonding layer 5 is the prior art, and details are not repeated herein, when the outer pipe 1 needs to be taken out of an esophagus, the semicircular sheets of the outer pipe 1 are broken outwards and pulled outwards, the inner pipe 2 is fixed by hands, and therefore the outer pipe 1 is separated from the inner pipe 2; when the inner tube 2 needs to be taken out of the esophagus, the semicircular sheet of the outer tube 1 is firstly broken to expose the inner tube 2, the outer tube 1 is fixed by hands, the inner tube 2 is pulled out of the outer tube 1, and the semicircular sheet of the inner tube 2 can be broken in the process of pulling the inner tube 2, so that the inner tube 2 is separated from the outer tube 1.

The inner diameter of the outer tube 1 is 3mm, the inner diameter of the inner tube 2 is 2mm, the lengths of the outer tube 1 and the inner tube 2 are both 130cm, and the size accords with the embedding size of the jejunum tube.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
