Description

The split type compressor of intravenous urography

Technical field

This utility model relates to medical apparatus and instruments, is specifically related to the split type compressor of a kind of intravenous urography.

Background technology

Intravenous urography [IVP] is urinary system x-ray inspection method commonly used, although the large-scale image documentation equipment such as current MRI.CT.US has some superiority in the inspection of relevant disease, intravenous urography is understood renal function in observation and is had especially its unique one side at the aspects such as inspection of Ureteral Obstruction pathological changes when checking urologic disease.In recent years, along with the continuous renewal development of contrast agent and x-ray equipment, the picture quality of intravenous urography is greatly improved.But how to check technology at good contrast agent and the supporting lower further improvement IVP of digital X-ray machine? is raising improved in the aspects such as comfortableness of how just to shorten the review time, reduce radiation, improving patient? remain the problem that need solution of pendulum in face of us in this work.

According to individual long-term investigation, the special-purpose compressor of intravenous urography is still unified the finished product of production on the medical market at present, each hospital substantially all is homemade abdominal part 360 degree cluster bellybands, or the random seat belt of some Imported adds, and pad carries out whole bilateral compressing as the compressing head in the various self-controls, exist the compressing scope large, pressure point is selected the problems such as inadequate science.When inconsistent as developing when two kidneys, can only wait for by time-delay, not only the time-consuming efficient of taking a lot of work is low, and patient is longer by the bellyband binding time, and uncomfortable Proportion of patients accounts for 100%.

During radiography, be conducive to diagnosis in order to make the full form satisfaction of renal pelvis renal calices, usually all to pressurize at abdomen anterior [hypomere in the sacroiliac joint leading edge ureter].By oppressing to control or block contrast agent flows to bladder from kidney speed, the normal kidney of general utility functions all can rapid development about 5 minutes, have in pathological changes one side or the renal dysfunction situation, Ipsilateral Fen can occur secretes hypofunction and develops not good or the sign of not developing, when conventional contrast examination, only have this moment by prolonging pressing time and wait for the wait development, because a normal side and Ipsilateral are in simultaneously by the interlock compressing, developing simultaneously for the both sides kidney sharp with worn-out contradiction state just occurs.Develop a good side under compressor control for normal renal function, can slow down the contrast agent drainage rate and can guarantee to have in the blood enough contrast concentrations to keep, develop to promote offside renal pelvis renal calices.As will constantly flowing to bladder from kidney through ureter without the strong side contrast agent of compressor.Along with the reduction of contrast concentration in the blood, the poor unusual side kidney that then is unfavorable for developing is full to be shown.So in time, oppresses a normal side and is very important.Develop not good or do not develop such as the poor side of renal function, this moment is under the extruding of compressor, more suppress so that function is secreted in Ipsilateral kidney Fen, the on the contrary more slow even development of developing is because ureter is not only oppressed in compressing, also oppress simultaneously common iliac artery and sympathetic trunk, the ureter pressurized causes urinary tract obstruction, and ureter and hydrostatic pressure in Bowman's space power raise suddenly and reduced the effective filtration pressure of glomerule, and filtration rate reduces, contrast agent can not gather renal pelvis and develop badly, or does not develop.And the sympathetic trunk pressurized stimulates the sympathetic activation visceral vessel to shrink, and renal blood flow or plasmaflux significantly reduce, and glomerular filtration rate significantly descends, and contrast agent causes development bad in the obvious minimizing of gathering of renal pelvis.Need to pressurize and Ipsilateral when not pressurizeing when strong side this moment, is conducive on the contrary the bad kidney Fen of function and secretes development.

The conventional IVP review time generally all about 30 minutes in addition the time longer because human peripheral bundlees with bellyband, there is block object extruding the abdomen front portion, causes the circulation of abdominal visceral browser pressure rising body to be under some influence, uncomfortable degree is well imagined.

Investigate through many hospitals, many sphygomanometer rubber bag, cotton pad, triangle wooden units etc. all used when doing contrast examination are made as underbed body in the compressing head certainly, used pressure method all is human body 360 degree bellyband bindings mostly, it is loaded down with trivial details when the doctor operates, because the long checking efficiency of contrast time can not get improving, and outmoded binding mode all can not adapt to for the old and the weak, child, Abdominal Masses, postoperative patient.Compressing was a unsolved bottleneck problem always during IVP checked, therefore also derive the multiple IVP inspection method that need not oppress, as: the high position change of the low foot of head method, large or IV dripping in low dosage method, low Zhang method of medicine etc., but all can not promote the use of because of all worn-out ends.1998.12.865. China's radiation magazine has been published " design of IVP controllability compression band and application " [patent].
