The utility model discloses after the seal wire was withdrawn from, because the memorability of material ability, pipe head end screw -tupe flexion was crooked naturally, and this kind of design is favorable to through the pylorus to can stop in the small intestine enteric cavity with the state of ideal. All scribble hydrophilic ultra -smooth coating or hydrophobic coating in catheter surfaces's the hydrophilic ultra -smooth coating, seal wire surface and pipe inner wall, can be very convenient pass through can make the seal wire not have the twitch of hindrance during the nasal cavity inserts the stomach.
Description
Technical field
This utility model relates to a kind of medical aid tool, particularly to a kind of nasointestinal tube.
Background technology
In traditional field, for patients such as performing the operation, go into a coma, stomach can not be taken food, the most generally with gastrointestinal tract feeding and the infusion of nutritional solution, typically pass through nasal cavity along esophagus entrance duodenum or small intestinal by nasal feeding, i.e. conduit.For the ease of inserting smoothly, it is desirable to conduit has certain hardness, and there is elasticity it is difficult to give a discount.Doctor is often that the insertion of conduit is time-consuming clinically, and especially to insert duodenal patient, conduit is the most difficult through pylorus；For needing the patient of nasal feeding for a long time, it is replaced as frequently as conduit and can bring misery to patient, also increase the workload of medical worker.
In order to preferably solve above-mentioned problem, there are now production and the exploitation of nasointestinal tube, but these nasointestinal tubes have been constantly present such-and-such problem, used Shi Shangzeng to have seal wire extraction difficulty, conduit gives a discount, and not readily passes through pylorus and enters the dangerous appearance such as duodenum.The existence of this danger, causes hidden danger to patient, the most once produces this situation and will result in serious consequence, even threatens the life of patient, affected the therapic opportunity of patient adversely, bring great misery to patient and families of patients.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that a kind of reasonable in design, is used conveniently and safely, inserts nasointestinal tube easily.
Technical problem to be solved in the utility model is to be realized by following technical scheme, this utility model is a kind of nasointestinal tube, it is characterized in: include conduit tube component and Yarn guide component, described Yarn guide component includes that the seal wire of seal wire and fixing seal wire fixes seat, the head end of seal wire is provided with circular glue head, and the surface of described seal wire scribbles hydrophilic superslide coating or hydrophobic coating；Described conduit tube component includes the conduit that front end is closed, the tail end of conduit connects multipurpose joint, the leading section of described conduit is provided with elastic bend part, it is the annulus of 2-4cm that elastic bend part natural torsion forms 2-3 loop diameter, it is provided with 4 symmetrically arranged through holes in the conduit both sides of elastic bend part head end, described seal wire is inserted in conduit, and conduit elastic bend part stretches, and seal wire is fixed the tail end of seat and stretched out outside multipurpose joint；It is coated with hydrophilic superslide coating on the outer surface of described conduit, the inner surface of described conduit scribbles hydrophilic superslide coating or hydrophobic coating.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described nasointestinal tube: described elastic bend part natural torsion forms the annulus that 2.5 loop diameters are 3cm.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described nasointestinal tube: the total length of described conduit elastic bend part is 19-28cm.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described nasointestinal tube: the tube wall of described conduit is provided with developing line, and the side of developing line is provided with scale.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described nasointestinal tube: described multipurpose joint is provided with and its open-ended block coordinated.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described nasointestinal tube: described block is provided with medicine feeding hole, and medicine feeding hole is provided with the dosing block being connected with block.
Compared with prior art, when seal wire of the present utility model is inserted in conduit, conduit screw type bending section is stretched by seal wire, it is easy to insert in stomach by nasal cavity, after seal wire is withdrawn from, due to the memory performance of material, conduit head end screw type bending section natural torsion, this it is designed with beneficially by pylorus, and can rest in small intestinal enteric cavity with preferable state.The circular glue head of seal wire head end avoids seal wire to scratch conduit, damage mucosa and skin.Supravasal multipurpose joint, general connector and female Luer syringe, filling apparatus and intestinal provisions device joint match.There is hydrophilic superslide coating on the surface of conduit, can be inserted in stomach by nasal cavity very easily.All scribble hydrophilic superslide coating or hydrophobic coating on described seal wire surface and pipe inner wall, the without hindrance twitch of seal wire can be made, seal wire after having intubated, can be quickly drawn out.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation that seal wire extracts rear tube out.
Detailed description of the invention
Referring to the drawings, concrete technical scheme of the present utility model is further described, in order to those skilled in the art is further understood that the present invention, and does not constitute the restriction to its right.
Seeing figures.1.and.2, a kind of nasointestinal tube, including conduit tube component and Yarn guide component, described Yarn guide component includes that the seal wire of seal wire 4 and fixing seal wire 4 fixes seat 1, and the head end of seal wire 4 is provided with circular glue head, and circular glue head can avoid seal wire 4 to scratch conduit.Described conduit tube component includes the conduit 6 closed front end, and the tail end of conduit 6 connects has multipurpose joint 2, described multipurpose joint 2 to be provided with and its open-ended block 5 coordinated.Described block 5 is provided with medicine feeding hole, and medicine feeding hole is provided with the dosing block being connected with block.Medicine feeding hole coordinates with the female Luer of syringe, and multipurpose joint matches with filling apparatus and intestinal provisions device joint.Conduit 6 material uses white roentgenopaque polyester material, is beneficial to observe the particular location of conduit.Use polyester material, its good biocompatibility, to body without obvious stimulation, reduce the stimulation to nasopharynx throat and various complication.The tube wall of described conduit 6 is provided with developing line, and the side of developing line is provided with scale.Conduit 6 develops under X-ray, can see that conduit present position after such insertion.
