Abstract
The invention belongs to medical instruments and particularly relates to a dual-purpose nasointestinal tube. The dual-purpose nasointestinal tube comprises a tube body (1) which is composed of a top complete section (11), a middle separated section (12) and a bottom complete section (13), the middle separated section (12) is separated into a cavity A (3) and a cavity B (4) by a separating wall (2) arranged in the length direction of the tube body (1), and the cavity A (3) is communicated with the top complete section (11) and the bottom complete section (13) to form a nasointestinal tube channel. A branch tube (5) is arranged on the top of the cavity B (4), the bottom of the cavity B (4) is a blind end, side holes (6) are formed in the outer wall of the bottom of the cavity B (4), and the cavity B (4) and the branch tube (5) form a nasogastric tube channel. The dual-purpose nasointestinal tube has the functions of a nasogastric tube and the nasointestinal tube, and the blocking rate of the nasointestinal tube is low.
Description
Technical field
The invention belongs to medical apparatus and instruments, particularly a kind of dual-purpose nasointestinal tube.
Background technology
Nasointestinal tube is a kind of polyurethane pipe of X-ray opaque.When use, nasointestinal tube is stretched by guiding steel wire, inserts the rear seal wire that takes out in stomach, and nutrient substance arrives intestinal tube intestinal through nasointestinal tube.In clinical care, nasointestinal tube and nasogastric tube often need to insert patient nostril simultaneously, increase the working strength that has also greatly increased medical personnel painful time to patient.Application number is that the innovation and creation of 200920068314.X disclose a kind of separable Nasal gastrointestinal tube, comprises nasogastric tube, nasointestinal tube, and Nasal gastrointestinal tube adopts two-chamber embedded design, and nasogastric tube possesses fluted compared with Large Diameter Pipeline and a side, can embed nasointestinal tube.This scheme can disposablely be inserted simultaneously and carry out the nasogastric tube of gastrointestinal drainage decompression and the nasointestinal tube that enteral nutrition is supplied with, and nasogastric tube can separate and remove respectively after inserting with nasointestinal tube.The weak point of this scheme is: the plugging rate of nasointestinal tube is very high.During tradition is clinical, nasointestinal tube and nasogastric tube respectively account for nostril of patient, because nasointestinal tube is thinner, often stop up, if it is inserted from a nostril together with nasogastric tube, total cross section of nasogastric tube and nasointestinal tube can not infinitely increase again, and the plugging rate of nasointestinal tube will increase greatly.
Summary of the invention
The object of this invention is to provide a kind of dual-purpose nasointestinal tube, this dual-purpose nasointestinal tube has not only played the effect of nasogastric tube, and the plugging rate of nasointestinal tube will reduce greatly.
The scheme that the present invention solve the technical problem is: a kind of dual-purpose nasointestinal tube, comprise body, body is made up of three sections of top complete segment, middle part compartmented, bottom complete segment, middle part compartmented is by being separated into A cavity and B cavity along the partition wall of body length direction setting, and A cavity is communicated with formation nasointestinal tube passage with top complete segment, bottom complete segment; The top of B cavity is provided with an arm, and the bottom of B cavity is cecum, on the outer wall of B cavity bottom, offers side opening, and B cavity, arm form nasogastric tube passage.
Body of the present invention plays the effect of nasointestinal tube and nasogastric tube simultaneously, inserts a body and is equivalent to insert nasointestinal tube and nasogastric tube simultaneously.The body of this programme is made up of three sections of top complete segment, middle part compartmented, bottom complete segment.Top complete segment, bottom complete segment refer to not be separated wall separately in the middle of it, are only complete circular channels.The diameter of top complete segment, middle part compartmented is consistent with the diameter of nasogastric tube of the prior art.The diameter of bottom complete segment both can be consistent with the diameter of nasogastric tube of the prior art, also can be consistent with the diameter of nasointestinal tube of the prior art.The low reason of plugging rate of nasointestinal tube is: 1, the existence of top complete segment, and make the top of nasointestinal tube passage have one section of large aperture, for the space of accommodating enteral nutrient solution, increase the gravitional force of body top enteral nutrient solution; 2, between A cavity and B cavity only by one deck partition wall, in the time that nasogastric tube passage is worked, the thing of stomach, in the process being sucked out, produces larger vibrations to nasointestinal tube passage, vibrations contribute to the enteral nutrient solution of top complete segment dirty.
As further technical scheme, the length of described top complete segment is 4～10 centimetres, and the length of described middle part compartmented is 40～60 centimetres, and the length of described bottom complete segment is 65～80 centimetres.
Top complete segment is too short, and the gravitional force of enteral nutrient solution is large not; Top complete segment is long, inadequate to the vibrating effect of nasointestinal tube passage when nasogastric tube passage carries out stomach drain.In addition, the length of middle part compartmented and bottom complete segment is set according to body dimension.
As technical scheme further, the inwall of described nasogastric tube passage has a trachea, and the top of trachea is positioned at the top of arm, the bottom of trachea and nasointestinal tube channel connection.
As technical scheme further, the bottom of described trachea is positioned at the junction of middle part compartmented and bottom complete segment.
Nasogastric tube passage is in work, and trachea is found time by the negative pressure of joining with nasogastric tube passage simultaneously, makes the pressure minimizing of middle part compartmented and complete segment junction, bottom, and enteral nutrient solution is more easily dirty.
In sum, the present invention has advantages of novel structure, successful, a pipe has the effect of nasogastric tube and nasointestinal tube under the prerequisite that does not increase aperture simultaneously, and the plugging rate of nasointestinal tube is lower, can significantly reduce patient's misery and medical personnel's working strength.

Detailed description of the invention
Embodiment 1
As shown in Figures 1 to 3, a kind of dual-purpose nasointestinal tube, comprise body 1, body 1 is made up of 13 3 sections of top complete segment 11, middle part compartmented 12, bottom complete segment, the length of top complete segment 11 is 4～10 centimetres, the length of middle part compartmented 12 is 40～60 centimetres, and the length of bottom complete segment 13 is 65～80 centimetres.The external diameter of top complete segment 11 and middle part compartmented 12 is 3.0 ± 0.5m, middle part compartmented 12 is by being separated into A cavity 3 and B cavity 4 along the partition wall 2 of body 1 length direction setting, the length of partition wall 2 is consistent with the length of middle part compartmented 12, and A cavity 3 is identical with the volume of B cavity 4.A cavity 3 is communicated with formation nasointestinal tube passage with top complete segment 11, bottom complete segment 13; The top of B cavity 4 is provided with an arm 5, and the bottom of B cavity 4 is cecum, on the outer wall of B cavity 4 bottoms, offers side opening 6, and B cavity 4, arm 5 form nasogastric tube passage.
The inwall of nasogastric tube passage has a trachea 7, and the top of trachea 7 is positioned at the top of arm 5, the bottom of trachea 7 and nasointestinal tube channel connection.The bottom of trachea 7 is positioned at the junction of middle part compartmented 12 and bottom complete segment 13.Trachea 7 is fixed on partition wall 2, is equivalent to hang weight on partition wall 2, makes the vibrating effect of partition wall 2 better.On the other hand, trachea 7 can also strengthen the water conservancy diversion effect of nasogastric tube passage.
