Technical Field

The utility model relates to the technical field of jejunum nutrition tubes, in particular to an anti-reflux jejunum nutrition tube.

Background

Jejunum nutrient canal is a method of maintaining nutrient intake in patients, and usually patients do not fully recover their stomach function after surgery, either by total intravenous injection of nutrient solution or by jejunal injection of enteral nutrient suspension, thereby allowing the patient to absorb nutrition. The jejunum nutrient canal is used by inserting jejunum nutrient canal directly from nasal cavity, entering stomach and jejunum from nasopharynx to esophagus, providing nutrient solution for patient. When the jejunum nutrition tube is used, the following problems exist:

because the patient is mostly lying down when using jejunum nutrient canal, when nutrient solution is in the in-process of suspending, the esophagus very easily will flow back the nutrient solution, leads to the user can not fine absorb the nutrient solution, leads to inconvenience such as waste of nutrient solution.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 6, an anti-reflux jejunum nutrition tube comprises a tube body 1, wherein a plurality of baffle sleeves 2 are connected in the tube body 1, the baffle sleeves 2 are arranged at equal intervals, the baffle sleeves 2 are arranged in a vertically through mode, the diameter of the baffle sleeves 2 is gradually reduced from top to bottom, and a current limiting assembly is connected in the tube body 1.

As shown in fig. 1, the anti-reflux jejunum nutrition tube is similar to the structure of the existing jejunum nutrition tube, and the main improvement point of the utility model is that the pipeline has an anti-reflux function, as shown in fig. 1 to 6, when the anti-reflux jejunum nutrition tube is used, after nutrient solution enters the tube body 1, the nutrient solution firstly flows forward through the flow limiting assembly, and the nutrient solution can enter the intestines of a patient through the baffle sleeve 2 in a downward and upward manner, and the nutrient solution can smoothly flow out through the baffle sleeve 2 due to the upward and downward through arrangement of the baffle sleeve 2, and the diameter of the baffle sleeve 2 is gradually reduced from top to bottom, when the liquid is reflux, a part of reflux liquid can be blocked by the reduced bottom of the baffle sleeve 2, and a plurality of baffle sleeves 2 are arranged, so that most of reflux liquid is blocked layer by layer, and finally the rest part of liquid is blocked by the flow limiting assembly, so that the liquid can not reflux.

As shown in fig. 2, 5 and 6, the current limiting assembly comprises a limiting ring 3 and a floating plate 4, wherein the limiting ring 3 is fixedly connected to the inner wall of the pipe body 1, the floating plate 4 is rotationally connected to the bottom of the limiting ring 3, a pull belt 5 is fixedly connected to one side, away from a hinge point, of the upper surface of the floating plate 4, the other end of the pull belt 5 is fixedly connected with the limiting ring 3, and the pull belt 5 is obliquely arranged.

Specifically, when the liquid passes through the baffle sleeve 2 and flows to the bottom of the floating plate 4, the flowing liquid has a certain impact, the floating plate 4 can be opened to impact, and the impacted floating plate 4 can rotate to prop against the limiting ring 3, so that the channel of the pipe body 1 is completely closed, and under the condition of gravity, a larger gap exists between the floating plate 4 and the limiting ring 3, and enough liquid flows downwards.

As shown in fig. 5 and 6, the diameter of the floating plate 4 is not smaller than the inner diameter of the retainer ring 3. By setting the diameter of the floating plate 4 not smaller than the inner diameter of the stopper ring 3, the floating plate 4 can be made to better abut against the stopper ring 3, thereby further increasing the effect of liquid blocking.

As shown in fig. 2 and 6, the floating plate 4 is hollow. This arrangement makes it easier for the floating plate 4 to be impacted by the liquid against the stop collar 3.

As shown in fig. 3 and 4, the top of the retaining sleeve 2 is fixedly connected with a connecting ring 21, and the connecting ring 21 is fixedly connected with the inner wall of the pipe body 1. This arrangement makes the connection of the sleeve 2 more stable.

As shown in fig. 1 to 4, the diameter of the bottom of the collar 2 is equal to the radius of the pipe body 1. By the arrangement, the blocking sleeve 2 can ensure the output of nutrient solution in the pipe body 1, and the effect of blocking the liquid layer by layer is better when the liquid flows back.
