In utility model, the control driver uses programmable PLC control system.
In order to clearly show the effect of the application device in actual use, applicant is by the application device and now
There is man-hour manually hand-held detection in technology to make following comparative testing:
One, protection safety problem
The angiography DSA equipment of 5 different models is chosen respectively, and with reference to GBZ130-2013, " medical X-ray diagnostics are put
Penetrate requirement of shelter " in about close-table operate radioprotective test method, 1.5mmCu plate is placed on standard water mould, water mould is then
It is placed in the center of irradiation field on diagnostic couch, diagnostic couch is adjusted to 250mm, automatic exposure at a distance from panadaptor, used
451P type ionisation detector tests the Air Kerma value of each operation position respectively.
Test result
5 DSA close-table operation defense controls testing results are shown in Table 1
Table 1
Injured dose estimation
As shown in Table 1, the maximum illumination that the first operation position may be subject to is 268 μ Gy/h, what the second operation position may be subject to
Maximum illumination is 223 μ Gy/h；To ensure that equipment can be used safely, GBZ130-2013 regulation: close-table operates defense controls should not
Greater than 400 μ Gy/h, while the shielding factor of 0.5mmPb is 1/26, and the shield effectiveness of lead protection device takes 2 times of safety coefficients.?
When radioactive protection monitors, monitoring personnel at least needs to expose 10 times, calculates every time by 4s, then one-time detection process exposes in total
40s.Therefore, for testing staff after dressing protective articles, normal condition monitors maximum possible next time can receive 0.34 μ Gy (400
μ Gy/h ÷ 26 × 2 × 40s ÷ 3600S/h), if 1 year monitoring close-table equipment 50 times, protective survey personnel will receive 17 μ Gy
Dosage irradiation；And in actual monitoring work, since hand needs to hold equipment, thus non-wearing gloves；Eyes are seen for convenience
See and comfortably, also do not wear lead protection glasses, at this point, arm and eyes crystal maximum agree to receive 4.44 μ Gy (400 μ Gy/h ×
40s/3600S/h), equally, 1 year monitoring DSA 50, machine, then protective survey personnel irradiate the dosage for receiving 222 μ Gy.According to
The saying for radiating deterministic effect, after human body receives to be more than the radiation irradiation of certain threshold dose, tissue mesopodium is enough thin
Born of the same parents will be killed or seriously damage, and have an impact to the allomeric function of organ, cause organ dysfunction.Certain organ exposures
The dose value (being shown in Table 2) of deterministic effect is generated afterwards.
Table 2
| Dosage (Gy) | Organ | Effect |
| 3.0 | Gonad | Permanent infertility |
| 5.0 | Eyes | Posterior cataracts are formed |
| 3.0 | Ovary | Infertility |
| 3.0 | Skin | Erythema |
| 1.0 | Marrow | Cell is reduced to be formed |
| 10.0 | Lung | It is dead |
| 0.1 | Fetus | There may be deformities |
Moreover, above calculate only considers the successful perfect condition of one-time detection.When actually detected, because of equipment under test parameter
Not right or protective equipment position is set and puts improper or data readings unsuccessfully and need the factors such as resurvey, often exposure dosage is practical
It is greater than perfect condition several times or ten times or more, it is most likely that be more than safety limit, such as will avoid radiating completely using the present apparatus
Harm.
Two, measurement accuracy and quality
By test we acquire second, third, fourth, penta, oneself 5 different people it is anti-to same DSA equipment close-table operation
Protect performance monitoring results；1 people of first is repeated 5 times close-table operation protective performance monitoring result to the DSA equipment；And it is using this
System carries out 5 close-tables to the DSA equipment and operates protective performance monitoring result, and details are shown in Table 3
The monitoring result obtained under 3 different experiments mode of table
It being analyzed by above data, the same person monitors 5 times, due to each measurement position of human body, the difference of time of measuring,
To which data discrete is larger；And different 5 people are even more because measurement habit, measurement position, the difference of time of measuring and measure
Data difference is bigger.The transmission of its X-ray protection monitoring data and support carrier system monitoring data consistency are substantially better than manually
Monitoring data, this system have been entirely capable of that testing staff is replaced to complete indoor radiation protection test assignment.Thus data are analyzed, continuously
Monitoring data are repeated, the present apparatus is defeated completely manually.
The utility model has the following beneficial effects: 1, avoid artificial detection personnel directly by or mediate contact radioactive ray, greatly
Protect testing staff's radioactive radiation safety.
2, when due to artificial detection, in order to protect testing staff, when detection, reduces time for exposure (radiated time) to the greatest extent, from
And the time for exposure is caused to be less than measuring instrument time response, it causes time complexity curve and increases measurement error.It, can be with when prosthetic detects
Longer exposure times are more than the measuring instrument response time without time complexity curve, to reduce measurement error link, it is ensured that entire inspection
It surveys more acurrate.
3, for manually detecting indoors, personnel when monitoring the fixed position points such as upper, middle and lower, miss when duplicate measurements by position
It is poor big, cause measurement data inaccurate.And mechanical movement means are run in strict accordance with programming, position is mobile accurate, and measurement misses
Difference is minimum.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
