Description
Technical field
The utility model is related to a kind of nasogastric tube, specifically a kind of anti-backflow nasogastric tube.
Background technology
EA is that Jing intestines and stomach provide the nutriment of metabolism needs and the nutritional support of other various nutrients, its
It is decided by time length, the state of mind and gastrointestinal function, the approach of EA there are oral and Jing conduits to be input into two methods, its
The mode of middle Jing conduits input mainly conveys nutrient solution to patient by nasogastric tube, in intensive care unit, many urgent patients
Cannot independently take food, be inserted using nasogastric tube via intranasal application and carry out nutritional supplementation in stomach or enter medicine, nasal feeding, i.e. nasal feeding are exactly
Nasogastric tube is sent in patient's stomach by nasal cavity, is sought food toward patient's stomach thing by nasogastric tube, be generally used for stupor or can not
The patient of oneself feed, because the time of nasogastric tube indwelling is up to 1-3 as long as the month, prolonged indwelling causes unavoidably nasal feeding pipe plug
Plug, further, since pressure is big in stomach and intestine, gastric content can backflow along nasogastric tube, and backflowing can increase nasal feeding blockage.
Utility model content
The purpose of this utility model is to provide a kind of anti-backflow nasogastric tube, to solve above-mentioned background technology in propose ask
Topic.
For achieving the above object, the utility model provides following technical scheme：
A kind of anti-backflow nasogastric tube, including upper connecting tube, lower connecting tube and stomach tube, the upper end of the upper connecting tube is provided with
For the opening coordinated with syringe, the lower end of upper connecting tube cooperatively forms dismountable sealing and connects with the upper end of lower connecting tube
Connect, the lower lower end of connecting tube cooperatively forms with the opening of stomach tube and is removably tightly connected, filtration dress is provided with lower connecting tube
Put, filter is screen pack, screen pack forms interference fit with the internal perisporium of lower connecting tube；The stomach of the lower connecting tube lower end
Pipe is provided with anti-backflow device, and anti-backflow device includes bulge, and the left and right sides of bulge is arranged with left wedge and the right side
Wedge；The end of the stomach tube is provided with the one-way valve for preventing that nutrient solution and medicine from flowing backwards.
Further, the outer surface of the stomach tube is coated with one layer of water activity lubricating layer.
Further, the left wedge and right wedge are medical grade elastic silica gel material.
Compared with prior art, filter is provided with lower connecting tube of the present utility model, the liquid food in syringe exists
Will first by filtering, so as to effectively prevent the blocking of stomach tube into before body；The outer surface of the stomach tube is coated with one
Layer water activity lubricating layer, can facilitate the injury of body insertion esophagus and reduction to patient's esophagus；Liquid is injected by syringe
During diet, because liquid diet is bent downwardly left wedge and right wedge in the squeezing action of syringe, food just can lead to
Bulge is crossed into the stomach of patient, injection liquid diet is finished, and the elasticity of the silica gel material of left wedge and right wedge is returned
In the presence of contracting power, the tip closure of two wedges prevents the effect of food reflux, while coordinating stomach so as to reach part
The one-way valve of the end of pipe together plays a part of to prevent from flowing backwards, and simple structure is practical.
Description of the drawings
Fig. 1 is the structural representation of anti-backflow nasogastric tube.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Refer to Fig. 1, a kind of anti-backflow nasogastric tube, including upper connecting tube 1, lower connecting tube 2 and stomach tube 3, the upper connection
The upper end of pipe 1 is provided with the opening 11 for coordinating with syringe, and the lower end of upper connecting tube 1 coordinates with the upper end of lower connecting tube 2
Formation is removably tightly connected, and the lower end of lower connecting tube 2 cooperatively forms with the opening of stomach tube 3 and is removably tightly connected, under
Filter 4 is provided with connecting tube 2, filter 4 is screen pack, and screen pack forms interference with the internal perisporium of lower connecting tube 2
Coordinate, the liquid food in syringe will first by filtering, so as to effectively prevent the blocking of stomach tube 3 before into body；Institute
The outer surface for stating stomach tube 3 is coated with one layer of water activity lubricating layer, can facilitate body insertion esophagus and reduce to patient's esophagus
Injury；The stomach tube 3 of the lower end of lower connecting tube 2 is provided with anti-backflow device 5, and anti-backflow device 5 includes bulge 51, bulge
51 left and right sides is arranged with left wedge 52 and right wedge 53, and left wedge 52 and right wedge 53 are medical grade bullet
Property silica gel material；The end of the stomach tube 3 is provided with the one-way valve 31 for preventing that nutrient solution and medicine from flowing backwards, and is injected by syringe
During liquid diet, because liquid diet is bent downwardly left wedge 52 and right wedge 53 in the squeezing action of syringe, food
Thing just can enter the stomach of patient by bulge, and injection liquid diet is finished, the silica gel of left wedge 52 and right wedge 53
In the presence of the elastic recovery force of material, the tip closure of two wedges, so as to reach the work for preventing food reflux of part
With while the one-way valve 31 for coordinating the end of stomach tube 3 together plays a part of to prevent from flowing backwards.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from this patent objective
Various changes can be made.
