Abstract
The utility model relates to a nose gastric tube, including tubing assembly and guidewire assembly, be equipped with 6-8 stainless steel steel balls in the front end of tubing assembly pipe, scribble hydrophilic lubricant coating on the surface of pipe, guidewire assembly includes the seal wire, and the head end of seal wire is equipped with circular gluey head, all scribble hydrophilic lubricant coating or hydrophobic coating on seal wire surface and the pipe inner wall. The utility model discloses there is hydrophilic lubricant coating on the surface of pipe, as long as soak it a period in the sterile water during use, water expansion is understood to hydrophilic coating, touches smoothness as the loach is surperficial, the intubate of being convenient for. At the intubate in -process, the pipe is flare -outed by the seal wire, is convenient for get into. The pipe is favorable to through the pylorus in the action of gravity of front end steel ball to can stop in the small intestine enteric cavity with the state of ideal. Seal wire and pipe inner wall are handled through lubricated, can make the seal wire not have the twitch of hindrance, and the seal wire can be taken rapidly out after accomplishing to the intubate.
Description
Technical field
This utility model relates to a kind of medical aid tool, particularly a kind of Nasal gastrointestinal tube.
Background technology
In traditional field, for patients such as performing the operation, go into a coma, stomach can not be taken food, usually carry out the infusion of nutritional solution clinically with Nasal gastrointestinal tube feeding, generally by nasal feeding, namely conduit is entered in Stomach duodenum or jejunum along esophagus by nasal cavity.For the ease of smooth insertion, require that conduit has certain hardness, and there is elasticity not easily give a discount, and need at lubricants such as catheter surface coating liquid paraffin.Doctor is often that the insertion of conduit is time-consuming clinically, and especially to inserting duodenal patient, conduit is just more difficult through pylorus; For the patient needing nasal feeding for a long time, change conduit continually and can bring misery to patient, also increase the workload of medical worker.
In order to better solve the above problems, there are now production and the exploitation of Nasal gastrointestinal tube miscellaneous, but always there is such-and-such problem in these Nasal gastrointestinal tubes, used Shi Shangzeng to have seal wire to extract difficulty, conduit gives a discount, and not readily passes through the danger such as cardia, pylorus and occurs.The existence of this danger, causes hidden danger to patient, often once produce this situation will cause serious consequence, even threatens the life of patient, has affected the therapic opportunity of patient adversely, brought 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, and provide a kind of reasonable in design, easy to use, intubate is easy to Nasal gastrointestinal tube.
Technical problem to be solved in the utility model is realized by following technical scheme, this utility model is a kind of Nasal gastrointestinal tube, be characterized in: comprise conduit tube component and Yarn guide component, described conduit tube component comprises the conduit that front end is closed, the rear end of conduit is connected with multipurpose joint, in the front end of conduit, be provided with 6 ~ 8 rustless steel steel balls, the duct wall at rustless steel steel ball rear be provided with some liquid outlets, the outer surface of described conduit scribble hydrophilic lubricant coating; Described Yarn guide component comprises the seal wire holder of seal wire and fixing seal wire, the head end of seal wire is provided with circular glue head, seal wire inserts in conduit, and seal wire holder stretches out outside multipurpose joint, and described seal wire surface and pipe inner wall all scribble hydrophilic lubricant coating or hydrophobic coating.
Conduit adopts polyester material, and good biocompatibility, to body without obvious stimulation, reduces the stimulation to nasopharynx throat and various complication.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described Nasal gastrointestinal tube: described liquid outlet is provided with 4, and staggered symmetry is located at the both sides of conduit.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described Nasal gastrointestinal tube: described rustless steel steel ball is provided with 8, is enclosed in conduit by glue.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described Nasal gastrointestinal tube: described multipurpose joint is provided with the block that coordinate open-ended with it.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described Nasal gastrointestinal tube: described block is provided with medicine feeding hole, and medicine feeding hole is provided with blocks a shot with the dosing be connected of blocking a shot.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, in described Nasal gastrointestinal tube: the tube wall of described conduit is provided with developing line, and the side of developing line is provided with scale.
Compared with prior art, there is hydrophilic lubricant coating on the surface of this utility model conduit, as long as it is soaked a period of time in sterilized water during use, hydrophilic coating meeting imbibition, touches up smooth as Misgurni anguillicaudati surface, be convenient to intubate.In catheterization procedure, conduit is stretching by seal wire, is convenient to enter.Conduit, in the action of gravity of front end steel ball, is conducive to by pylorus, and can rest on desirable state in small intestinal enteric cavity.Seal wire and pipe inner wall, through lubricated, can make the without hindrance twitch of seal wire, can extract seal wire out rapidly after intubate completes.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.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that seal wire extracts structural representation out.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
See figures.1.and.2, a kind of Nasal gastrointestinal tube, comprises conduit tube component and Yarn guide component, and described conduit tube component comprises the conduit 4 that front end is closed, and the tube wall of described conduit 4 is provided with developing line, and the side of developing line is provided with scale.Conduit 4 develops under X-ray, can see conduit 4 present position after such insertion.The rear end of conduit 4 is connected with multipurpose joint 3, and described multipurpose joint 3 is provided with the block 2 that coordinate open-ended with it.Described block 2 is provided with medicine feeding hole, and medicine feeding hole is provided with blocks a shot with 2 dosings be connected of blocking a shot.Medicine feeding hole coordinates with the female Luer of syringe, and multipurpose joint 3 matches with filling apparatus and intestinal provisions device joint.In the front end of conduit 4, be provided with 8 rustless steel steel balls 7, be enclosed in conduit 4 by glue.By the action of gravity of steel ball 7, be conducive to by pylorus, and can rest on desirable state in small intestinal enteric cavity.Conduit 4 tube wall at rustless steel steel ball 7 rear is provided with 4 liquid outlets, 5,4 liquid outlets 5 symmetry of interlocking and is located at the both sides of conduit 4.
