Description

A kind of fixed frame for internal arteriovenous fistula ultrasonic examination

Technical field

The utility model relates to the field of medical instrument technology, and in particular to a kind of for internal arteriovenous fistula ultrasonic examination Fixed frame.

Background technique

It is well known that haemodialysis is that uremic patient treats the important means to sustain life, many patient's first choice forearms Internal arteriovenous fistula is as dialyzing access, it suffices to say that, internal arteriovenous fistula is exactly the lifeline of uremic patient.Internal arteriovenous fistula operation Before, the internal diameter and flow velocity of ultrasonic evaluation upper arm blood vessel need to be applied, internal fistula, which is established, to be completed；Need ultrasound observation Arterialized vein journey Degree, assesses whether it can be punctured；In internal fistula use process, there is the trembling of internal fistula, noise weakens or disappears, dialysis hour hands Thorn is difficult, and blood flow decline when dialysis, dynamic vein pressure increases, access recycling increases, fistula side edema of limbs and trunks or pain, puncture Prolonged bleeding time afterwards doubts and examines narrow, thrombus, steals the complication such as blood, hemotoncus, aneurysm or vein Ectasia etc. any one Kind situation, requires sonographic evaluation.For sonographer, carefully effective check can provide more for Nephrology dept. doctor Add valuable information.But since forearm vein vessel position table is shallow, and tube wall is easy to be pressurized and collapse, if ultrasonic probe Contact skin carries out sliding measurement, and vein blood vessel may can be fallen by ultrasonic probe be collapsed, causes artificial narrow illusion, influences quiet Arteries and veins vessel diameter and the accuracy of flow velocity measurement.Therefore, patient's upper arm internal arteriovenous fistula should use in ultrasonic examination Enough couplants, probe touch skin, and gimmick is soft, do not press as far as possible to blood vessel.This just needs sonographer to work with the wrist raised, close The work of collection causes carpal canal pressure to increase, and carpal tunnel syndrome occurs in Median nerve compression, influences the work of sonographer.Internal fistula Flow need to measure vessel diameter and need to measure same calibration point flow velocity, and error slightly just has very greatly to internal fistula flow is calculated It influences, since doctor's wrist is hanging, without fulcrum, stability is poor, one-point measurement accuracy can not be held well, Influence whether the accuracy of ultrasound examination data, thus, it is simple, easy to use, with measurement supporting point to research and develop a kind of structure It is the task that the art currently faces for the fixed frame of internal arteriovenous fistula ultrasonic examination.

Summary of the invention

That the purpose of this utility model is to provide a kind of structures is simple, easy to use, doctor's wrist is avoided vacantly to check simultaneously The fixed frame for internal arteriovenous fistula ultrasonic examination with adjustable measurement supporting point.

In order to achieve the above object, the utility model uses following technical scheme, and one kind is examined for internal arteriovenous fistula ultrasound The fixed frame looked into, by bottom plate, hollow column, upright bar, crossbeam, shaft, top plate, support rail, knighthead, handwheel jackscrew, rubber Rubber mat and pillow composition, its main feature is that: the upper interval fixation hollow of two sides transversally on a plane of rectangular base plate longitudinal direction side is vertical Support rail is fixed between column, two hollow columns, fixed knighthead is spaced on support rail, and the knighthead other end is fixed On the edge of rectangular base plate longitudinal direction side；Upright bar is vertically fixed at bar-shaped beam bottom surface both ends, and the upright bar other end is inserted into sky respectively It is locked in heart column and by handwheel jackscrew；Fixed vertical shaft in the middle part of bar shaped top board undersurface, the dynamic cooperation insertion bar-shaped beam of shaft In the vertical through hole at middle part, bar shaped cambered surface pillow is fixed above bar shaped top plate, is consolidated in the upper plane of the rectangular base plate longitudinal direction other side Rubber pad is determined, to constitute a kind of fixed frame for internal arteriovenous fistula ultrasonic examination.

When the utility model is used, the arm of patient is integrally placed on the rubber pad of bottom plate, doctor holds ultrasound and visits Wrist is placed in the bar shaped cambered surface pillow as fulcrum by head, carries out discontiguous ultrasonic examination, pillow distance to patient's arm The height of patient's arm can be adjusted by flexible in hollow column of upright bar, and be locked by handwheel jackscrew, bar shaped cambered surface Pillow adjusts measurement supporting point, it can be achieved that flat scanning inspection to patient's arm by rotation of the shaft on crossbeam.

The utility model structure is simple, it is easy to use, avoid doctor's wrist from vacantly checking, mitigate doctor's wrist pressure, surpass Sound one-point measurement is accurate, has reached goal of the invention.
