Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of small intestinal double contrast radiography conduit, as depicted in figs. 1 and 2, comprises flexible pipe 2, and flexible pipe 2 near-end is fixedly connected with traction pendant 3, and traction pendant 3 inside offers through hole 6, and through hole 6 communicates with flexible pipe 2 is airtight.Described traction pendant 3 is rotary body.The ridge 5 of shape is threaded outside described traction pendant 3.Described traction pendant 3 comprises head 7, waist 8 and afterbody 9, and the external diameter of any one cross section of waist 8 is all less than the maximum outside diameter of head 7 and afterbody 9 cross section.Described traction pendant 3 is dumbbell or gourd shape.Described traction pendant 3 is metallic object.Described flexible pipe 2 is the microtubular of elongated flexible, surperficial superslide, and flexible pipe 2 far-end is airtight is fixedly connected with tee T 1, and afterbody 9 one of described traction pendant 3 is fixedly communicated with connection tube 4, and connection tube 4 fixedly communicates with flexible pipe 2 is airtight.
A kind of using method of small intestinal double contrast radiography conduit, it is characterized in that, step is as follows: patient gets end sitting position, traction pendant 3 is put into stomatosis people, warm water delivery service is swallowed, flexible pipe 2 is positioned at external, after half a minute, patient drinks warm water 100-200ml again, and after 3-5 minute, patient gets right arm reclining, is observed the position at traction pendant place after 15 minutes by x-ray fluoroscopy, do not arrive in duodenal bulb as drawn pendant 3, then patient continues right arm reclining, is observed once by x-ray fluoroscopy every 15 minutes, until traction pendant 3 arrives in duodenal bulb; Treat that traction pendant 3 has arrived in duodenal bulb, then syringe is connected with the tee T being reserved in extrabuccal flexible pipe far-end, inject positive contrast's agent, then be connected with tee T with air bag, pressurization gas injection 500-1000ml, observes the full situation after little enteral positive contrast agent and gas and vapor permeation, as contrast medium under x-ray fluoroscopy fills defective under x-ray fluoroscopy, then repeatedly in tee T, inject positive contrast's agent and gas again, until meet the full requirement of small intestinal double contrast radiography; If reach requirement full, then taking x-rays is diagnosed disease of intestine for doctor in good time; As radiography is qualified, x-ray fluoroscopy and take the photograph sheet and can meet doctor to after the diagnosis needs of disease of intestine, slowly lifts flexible pipe 2, is slowly extracted out from patient's mouth by traction pendant 3.The temperature of described warm water is 30-50 DEG C.Described positive contrast's agent is iohexol solution 50-100ml or barium sulfate weak solution 200-500ml.
Flexible pipe in the present invention is the microtubular of an elongated flexible, surperficial superslide, flexible pipe front end connects dumbbell shape traction pendant with holes, the dumbbell shape traction pendant with holes made requires its smooth surface and is threaded shape ridge, is conducive under the wriggling of esophagus, stomach by cardia pipe, pyloric canal and enter duodenum.
The patient's direct oral cavity warm water checked is needed naturally to swallow the traction pendant of bottom hose front end, under the effect that traction falls self gravitation and Human Physiology wriggling function, traction pendant traction flexible pipe front end enters in duodenum in the lump, its flexible pipe far-end to be then reserved in outside oral cavity and connecting tee pipe, contrast examination can be carried out through tee T injection air and contrast medium with syringe, patient's no pain is without danger, and be easy to accept, result of use is good.
In the present invention, the perforated metal body of traction pendant dumbbell shape, the front projection of traction pendant is of a size of 0.5cm*2cm, hose length is about about 80cm, external diameter is 0.04mm, making material is the soft materials such as the polrvinyl chloride of medical poisonless, and its far-end connects a tee T, convenient and syringe or airbags during use.
It is to allow traction pendant under the peristaltic forces effect of self gravitation and esophagus, stomach that traction pendant is designed to dumbbell shape, when by cardia pipe and pyloric canal, its front end enters after in above-mentioned pipe, the eel-like figure part of dumbbell shaped is fixed under the effect of esophagus, gastric peristalsis contraction wave, can prevent traction pendant slippage and retrogressing.
The center of traction pendant, along its length with through hole, is the passage entering small intestinal after being connected with flexible pipe for gas during radiography and positive contrast's agent.
Traction pendant surface, in screw-like, being to increase certain frictional force, being easy to push ahead under the wriggling of esophagus, stomach and enter in duodenum.Because esophagus, gastric mucous layer have a large amount of mucus to adhere to, if traction pendant surface is too sliding, not easily push ahead.
The connection tube of traction pendant one end ledge is used for being connected with flexible pipe.
Flexible pipe is for connecting traction pendant and threeway, and its purposes is by sacculus or syringe pressurization gas injection and injects positive contrast agent, thus enters little enteral and carry out radiography, namely reaches the object of small intestinal double-end profiler.
Using method of the present invention is: patient gets end sitting position, traction pendant with holes for dumbbell shaped is put into mouth, warm water delivery service is swallowed, to swallow and under action of gravity, dumbbell shaped traction with holes pendant is very fast enters gastric by esophagus, then patient gets right arm reclining, under the effect of gravity and gastric peristalsis, draw pendant enters in duodenal bulb, now need patient under x-ray fluoroscopy, observe the position of dumbbell shaped traction pendant with holes, as arrived precalculated position, namely in duodenal bulb, then syringe is connected with the tee T being reserved in extrabuccal flexible pipe far-end, inject positive contrast's agent, as iohexol solution 50-100ml, or barium sulfate weak solution 200-500ml, be connected with tee T with air bag again, pressurization gas injection 500-1000ml, enough gas is by full for small intestinal expansion, by mucous membrane of small intestine uniform application after positive contrast's agent injection, the gas that little enteral fills be applied in the opaque contrast medium of intestinal mucosa at x-ray fluoroscopy, black-and-white image is shown under taking the photograph sheet, observe the full situation after little enteral positive contrast agent and gas and vapor permeation under x-ray fluoroscopy, in good time taking x-rays is diagnosed disease of intestine for doctor.As full in contrast medium under x-ray fluoroscopy dissatisfied, can repeatedly inject positive contrast's agent and gas, to meet the requirement of small intestinal double contrast radiography.As satisfied in radiography, x-ray fluoroscopy and take the photograph after sheet meets and need the diagnosis of disease of intestine, slowly extracts out flexible pipe and dumbbell shaped traction pendant from oral cavity.
