Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of protective shield unit of the x-ray protection device for angiography machine catheter bed.
Background technology
Some as clinical operations such as angiography and interventional therapys in, need to rely on the X ray that penetrates patient body by angiography machine and form image.For avoiding X-radiation to leak, protection operator safety, must arrange radioprotector angiography machine is other, and this preventer generally adopts material more than 0.5mm lead equivalent to make, in order to block X-radiation.
The other preventer of bed needing clinically should meet: protection effect is sure, flexible for installation, easy and simple to handle, does not affect operator's operation, can tackle the demand of various changing positions and position in art.
As shown in Figure 1, current preventer is generally comprised of three-piece: protective shield 1, and for bed top is divided and carried out radiation protection, it is fixed on ceiling, between protective shield and fixing point, there are the balance arm of force and at least two above flex points, for operator, pull and locate protective shield; The lower cutting means enclosure 2 of bed, carries out radiation protection for bed bottom is divided, and it is fixed on the other track of angiography lathe, and this track is the catheter bed standard configuration part of such clinical operation; The other protective plate 3 of bed, for eliminating the gap between the lower cutting means enclosure of suspention protective shield and bed, it is fixed on a lower cutting means enclosure.In radiography, be under radiation environment, suspention protective shield 1, the lower cutting means enclosure 2 of bed and the other protective plate 3 of bed are used in conjunction with simultaneously, all in the best, block position, just can reach best Radioprotective Effect (as Fig. 1, gapless comparatively speaking between suspention protective shield 1, the lower cutting means enclosure 2 of bed and the other protective plate 3 of bed, protection effect is best).Before each use, operator, according to radiography needs, adjusts the lower cutting means enclosure 3 of bed and is secured by bolts on an ad-hoc location in by-track road, in art, cannot readjust position.After sterilization, paving list, operator adjusts the position of suspention protective shield, is tried one's best near patient, blocks the Secondary radiation from patient body reflection.
The protective shield of above-mentioned existing preventer at least has following defect:
(1), in order to show the different regions of anatomy, or observe the traveling of conduit, in the clinical operation processes such as angiography or intervene operation, need frequent lateral or longitudinal movement catheter bed.Once bed surface moves, being fixed on the other preventer of bed (the lower cutting means enclosure 2 of bed and the other protective plate 3 of bed) moves with bed, and the protective shield 1 that is suspended in roof can not move with bed surface, therefore, the original the best that protective shield 1, the lower cutting means enclosure 2 of bed and the other protective plate 3 of bed form is blocked position and is misplaced, and then causes between protective shield 1 and the lower cutting means enclosure 2 of bed, the other protective plate 3 of bed and have gap, and its best is blocked position relationship disintegration, easily cause radiation leakage, injury operator.
(2), concerning operator, in intervene operation, maximum radiation source is the Secondary radiation from patient body reflection, therefore requires the protective shield 1 close patient body of will try one's best.When bed surface moves, protective shield 1 can not move with bed, and then cause in mobile catheter bed process, protective shield 1 cannot continue to keep to mix up in advance as far as possible near patient's protective position relation, therefore, once mobile catheter bed has not only destroyed the best of breed position relationship between the lower cutting means enclosure 2 of protective shield 1 and bed, the other protective plate 3 of bed, and make protective shield 1 away from patient, cannot guarantee the protection effect for the Secondary radiation from patient body reflection.
(3), in operation process, after each mobile catheter bed bed surface, preventer for fear of dislocation cannot be proceeded effective radiation protection, have to readjust protective shield position, protection effect in adjustment process cannot guarantee, and adjustment process has extended operating time, increased patient's infection probability, and then increased the risk of operation.
(4), protective shield 1 hangs on conduit room's ceiling, make the handling of this preventer need to destroy the infrastructure such as ceiling, shipping and delivery cost is high, difficulty is large, especially, once position is fixed, be generally difficult to mobile this preventer to other sick beds or conduit room, for meeting, perform the operation in time, certainly will need more preventer is installed, increase the equipment expenditure of hospital, and easily cause the problem of indivedual this preventer length standby time and waste hospital space resource.
For this reason, this utility model provides a kind of protective shield unit being directly installed on a lower cutting means enclosure (being cutting means enclosure unit).
