A kind of peel stomach tubeTechnical field
The utility model medicine equipment, especially a kind of peel stomach tube.
Background technology
Stomach tube（Nose catheter, nasogastric tube feeding）Nasogastric tube stomach tubes are inserted by nostril, via pharyngeal, are led toCross oesophagus reach stomach, be mostly for taking out gastric juice, it is also possible to in dealing stomach inject liquid be supplied to the necessary food of patient andNutrition, should be noted that during nursing and avoids stomach tube from polluting, and stomach tube abjection, cause to inhale by mistake.As China Patent Publication No. isA kind of 204910149 stomach tubes with filtering function, are related to field of medical article technology, including stomach tube main body, and its upper end is provided withPerfusing hole, the closed end of the stomach tube main body is provided with multiple side openings, and the entrance point detachable connection of the perfusing hole hadFilter, the filter includes integrally formed bottom and the ring wall being connected with bottom, and the bottom is provided with filter screen, the ring wallFixing device is provided with to be connected with stomach tube main body.This kind of stomach tube is straight tube, after stomach tube insertion human body is interior, the easy play of stomach tube, veryTo being pulled out.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of peel stomach tube, it is not easy to fall off, operationIt is convenient.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of peel stomach tube, the stomach tube includesBody, the tail end closing of the body, the front opening of body, the tail end side of body is provided with more than one side opening, describedThe inner space of side opening and body, the body is provided with one section of bending pipeline section, the side of the bending pipeline section near front positionMore than one otch is provided with, the otch is circumferentially evenly distributed；Traction seal wire, the traction seal wire are provided with the bodyOne end be fixed on the tail end of body, the other end for drawing seal wire is drawn by the opening of front end.The utility model implementation principle：Before in stomach tube insertion human body, traction seal wire is in relaxed state, and body is essentially straight tube state；Body is passed through into nostril or pharyngealIn insertion stomach, after the front end of body reaches stomach, doctor draws seal wire in the front-end operations of body, because body is near tail end positionPut and be provided with bending pipeline section, bending pipeline section is provided with otch so that bending bend pipe is easier to be bent, and traction seal wire is tightened upAfterwards, the tail end of stomach tube can be bent to form back-off at bending pipeline section, and kink and people's in-vivo tissue of body offset, so as to preventBody is extracted and come off.
Used as improvement, the otch is elongated, and its length direction is consistent with the length direction of body.
Used as improvement, the wall thickness of the wall thickness more than body of the bending pipeline section, the intensity of powerful bending part makes it can be withBend repeatedly without being broken.
As improvement, the wire fixing clamp for fixed traction seal wire is provided with the front end of the body.Body tail end is pull-shapedInto after bending, by wire fixing clamp fixed traction seal wire so as to tubular form be shaped, doctor is facilitated to be performed the operation.
Used as improvement, the wire fixing clamp includes fixed plate and portable plate, and portable plate side is hinged with fixed plate, portable plate andJaws is formed between fixed plate, the traction seal wire passes through the jaws.
Used as improvement, the wire fixing clamp includes solidus groove and pinch roller, and the solidus groove includes inclined bottom surface and the bottom of positioned atThe side of face both sides, the side is provided with elongate holes, and the pinch roller is arranged in solidus groove and is articulated in both sides by rotating shaftSide on, it is described traction seal wire be located between bottom surface and pinch roller.
The beneficial effect that the utility model is brought compared with prior art is：
Because body is provided with bending pipeline section near end-position, bending pipeline section is provided with otch so that bending bend pipe is moreEasily it is bent, after traction seal wire is tightened up, the tail end of stomach tube can be bent to form back-off, the kink of body at bending pipeline sectionOffseted with people's in-vivo tissue, come off so as to prevent body from extracting.

Fig. 1 is the state diagram that stomach tube does not bend.
Fig. 2 is the state diagram after the winding folding of stomach tube.
Specific embodiment
With reference to Figure of description, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, 2, a kind of peel stomach tube, the stomach tube includes body 1, and body 1 is flexible pipe, the body 1Tail end 11 is closed, the front opening of body 1.The tail end side of body 1 is provided with more than one side opening 3, and side opening 3 is distributed in body1 side surrounding, the inner space of side opening 3 and body 1, for the transfusion in body 1 to be sent into stomach, or by gastric juice suction lineIn body 1.The body 1 is provided with one section of bending pipeline section 2 near end-position, and bending bend pipe is integrally formed with body 1, but bendingThe wall thickness of pipeline section 2 bends the intensity of pipeline section 2 to increase more than the wall thickness of body 1；The side of the bending pipeline section 2 is provided with oneOtch 21 above, the present embodiment is preferably more than three, and the otch 21 is circumferentially evenly distributed；The otch 21 is in stripShape, its length direction is consistent with the length direction of body 1；The otch 21 can weaken the buckling strength of bending pipeline section 2, make it moreEasily bending.Antacid traction seal wire 4 is provided with the body 1, one end of the traction seal wire 4 is fixed on the tail of body 1End seal is closed out, and the other end for drawing seal wire 4 is drawn by the opening of front end.It is provided with the front end of the body 1 and is led for fixationThe wire fixing clamp 5 of guide wire 4, the wire fixing clamp 5 includes fixed plate and portable plate, and portable plate side is hinged with fixed plate, portable plateJaws is formed between fixed plate, the traction seal wire 4 passes through the jaws.
The utility model implementation principle：Before in stomach tube insertion human body, traction seal wire 4 is in relaxed state, and body 1 is essentiallyStraight tube state；Body 1 is passed through in nostril or pharyngeal insertion stomach, after the tail end of body 1 reaches stomach, doctor is before body 1End operation traction seal wire 4, because body 1 is provided with bending pipeline section 2 near end-position, bending pipeline section 2 is provided with otch 21, makesBend pipe must be bent to be easier to be bent, after traction seal wire 4 is tightened up, the tail end of stomach tube can be bent to form down at bending pipeline section 2Button, kink and people's in-vivo tissue of body 1 offset, and are come off so as to prevent body 1 from extracting；The tail end of body 1 is by pull-shaped into bendingAfter shape, by wire fixing clamp fixed traction seal wire 4 so as to the shape of body 1 be shaped, doctor is facilitated to be performed the operation.
Embodiment 2
With embodiment except that, the wire fixing clamp include solidus groove and pinch roller, the solidus groove include inclined bottomFace and the side positioned at bottom surface both sides, the side are provided with elongate holes, and the pinch roller is arranged in solidus groove and by rotating shaftIt is articulated on the side of both sides, the traction seal wire is located between bottom surface and pinch roller.When needing to be fixed traction seal wire,Pinch roller is made to be rolled in solidus groove, because bottom surface is inclined-plane, pinch roller is walked in diverse location, the distance between pinch roller and bottom surface, be fixed for traction seal wire by pinch roller walking with bottom surface after contacting by difference.
