Description
Technical field
This utility model relates to calibrating and the test of radioactivity Medical Instruments, particularly a kind of remote control propeller for digital subtraction angiography equipment Inspection die body.
Background technology
Digital subtraction angiography (Digital Subtraction Angiography, DSA) is the angiography method of assisting imaging by electronic computer, is to be applied to clinical a kind of brand-new x-ray to check new technique.In order to guarantee the performance of digital subtraction angiography equipment, guarantee the reliable of check result, hospital and armarium supervision department need regularly with detection die body the indexs such as the simulated blood vessel minimum dimension to machine, spatial resolution, low contrast resolving power, contrast linearity to detect, see whether index changes, can meet description or national standard requirement.
Detecting die body is generally the simulation human vas that contains different levels of iodine (general a set of die body is made up of 7 templates) made from acryhic material.When detection, each piece die body will be measured by the working condition of actual clinical diagnosis, to under X ray conditions of exposure, distinguish mobile die body one by one, allow die body on pedestal at the uniform velocity by roentgen radiation x open country, observe subtracting the indexs such as shadow effect, resolving power and whether meeting related request of tested equipment with simulating blood mobile situation in blood vessel of having mixed developing agent.In other words adopt and subtract shadow module replacement diodone, injector replacement high-pressure injection, thereby the dynamic vascular completing under real-time exposure subtracts shadow function and performance detecting.For example, subtracting in shadow in real time, can skeleton background module image be eliminated and clear demonstration blood vessel image; In blood vessel module is propelled automatically, whether subtraction image there is " hangover "; The quantitative analysis of subtraction image medium vessels tumor/angiostenosis; Whether the spatial resolution of module image and contrast meet technical requirement.
At present, medical measurement department or other detection departments mostly need testing person's close-table and artificial forward operation from the DSA blood vessel calibrating die body of external import, thereby inevitably cause and advance the inaccurate of speed, occur artifact, not fogging phenomenon.And then impact is passed judgment on the calibrating that subtracts shadow performance indications.In addition,, due to close-table operation, staff's eyes, body, hands etc. are all exposed under X-ray ray sensitive part, all can accept to exceed the X-radiation of normal dose at every turn, and testing person's psychology is also exerted heavy pressures on.Therefore, detect unit although most of and purchased standard blood vessel die body, but calibrating to angioradiographic system or detect and can not normally carry out.
Offshore company has released a kind of propeller with the work of gas control mode in recent years, by hold air bag by pipeline air pressure by trachea and electric wire be delivered to die body complete to calibrating die body propelling.Though this pattern can make to do the operation of personnel's compartment, but Shortcomings, the one, advance speed uncertain (advancing speed, with operator, the grip difference of air bag is had to significant change), it is poor that next holds the not enough promotion of gasbag pressure die body reliability, can not meet the calibrating requirement to dissimilar machine; The 2nd, be difficult for realizing compartment manipulation.In practical operation, need wear to operating room from the radioprotective wire casing ditch of machine room connecting trachea, execute-in-place is very inconvenient, as directly caused radiation leakage through going into crack between a door and its frame from protective door, other medical worker and outpatients is formed to injury.
In existing document, also see some external electric plating propulsions, but generally be line traffic control, this all need to will carry out in advance pipeline passway in the time doing capital construction, want perforate difficulty through walls larger and hospital radiological department body of wall is thicker at home, and the propeller of import is expensive, be unfavorable for promoting the use of.
Domestic original Ye You minority producer carried out the angle of rake development of some remote controls, but because X-ray examination cell structure is special, in order to shield the effusion of lonizing radiation, inspection chamber six walls are all very thick concrete walls, door is to apply stereotype door, unique watch window is also to adopt super thick lead bearing glass, and radio signal is seriously shielded, and has affected the reliability of wireless remote control propeller work.Originally the instrument of design also needs to use 220V power supply to be used as power, be in workplace another pull the wire, and using neither be very convenient.Therefore most domestic hospital, in the time doing the relevant calibrating of DSA, still adopts manual operation, lags far behind, is unsuitable for the current situation of radiological medicine entirety science and technology.
