Abstract
The invention relates to the field of medical instruments, in particular to an X-ray protection device with an integrated structure for an angiography machine. The device comprises a protection screen unit, a protection curtain unit and a bedside sliding rail unit, wherein the protection screen unit is arranged on the protection curtain unit, and the protection curtain unit is fixed on the bedside sliding rail unit so as to enable the protection curtain unit and the protection screen unit to synchronously and horizontally move along a bedside. The protection device can synchronously move along with a bed, and in a moving process, the protection device is always in the best protecting state and close to a patient, so that the problem that the radiation, especially the secondary stray radiation caused by the rays reflected by the patient, can not be effectively shielded due to the movement of the bed surface of a conduit bed is effectively solved, and meanwhile, the problems of prolonged surgery time, increased surgery risk and the like that are caused by adjusting the protection screen unit during surgery in the prior art are effectively avoided.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of x-ray protection device with integral structure for the 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 doctor safety, must arrange radioprotector angiography machine is other, and this preventer generally adopts the above material of 0.5mm lead equivalent to make, in order to block X-radiation.
The other preventer of bed that needs clinically should meet: protection effect is sure, and is flexible for installation, easy and simple to handle, do not affect doctor's operation, can tackle the demand of various changing positions and position in art.
As shown in Figure 1, present preventer generally is comprised of three-piece: protective shield 1, be used for bed top is divided and carried out radiation protection, and it is fixed on ceiling, the balance arm of force and at least two above flex points are arranged between protective shield and fixing point, be used for the doctor and pull and locate protective shield; Cutting means enclosure 2, be used for the bed bottom is divided and carried out radiation protection, 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, be used for eliminating the gap between protective shield and cutting means enclosure, and it is fixed on cutting means enclosure.Be under radiation environment in radiography, the other protective plate 3 of protective shield 1, cutting means enclosure 2 and bed is used in conjunction with simultaneously, all be in the best and block position, just can reach the Radioprotective Effect of the best (as Fig. 1, gapless comparatively speaking between the other protective plate 3 of protective shield 1, cutting means enclosure 2 and bed, protection effect is best).Before each the use, the doctor, according to the radiography needs, adjusts cutting means enclosure 3 and is secured by bolts on an ad-hoc location in by-track road, can't readjust position in art.After sterilization, paving list, the doctor adjusts the position of protective shield, and it, as far as possible near the patient, is blocked the Secondary radiation from the patient body reflection.
Above-mentioned existing preventer has following defect at least:
(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, often need laterally or vertically move catheter bed.In case bed surface moves, being fixed on the other preventer of bed (the other protective plate 3 of cutting means enclosure 2 and bed) moves with bed, and protective shield 1 can not move with bed surface, therefore, the original the best that the other protective plate 3 of protective shield 1, cutting means enclosure 2 and bed forms is blocked position and is misplaced, and then causes between protective shield 1 and cutting means enclosure 2, the other protective plate 3 of bed and have gap, and its best is blocked the position relationship disintegration, easily cause radiation leakage, the injury doctor.
(2), concerning the doctor, in intervene operation, maximum radiation source is the Secondary radiation from the 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 can't continue to keep the as far as possible close patient's who mixes up in advance protective position relation, therefore, in case mobile catheter bed has not only destroyed the best of breed position relationship between protective shield 1 and cutting means enclosure 2, the other protective plate 3 of bed, and make protective shield 1 away from the patient, can't guarantee the protection effect for the Secondary radiation from the patient body reflection.
(3), in operation process, after each mobile catheter bed bed surface, preventer for fear of dislocation can't be proceeded effective radiation protection, have to readjust the protective shield position, protection effect in adjustment process can't guarantee, and adjustment process has extended operating time, has increased patient's infection probability, and then has increased the risk of operation.
(4), the other protective plate 3 of cutting means enclosure 2 and bed is immovable is fixed on the other track of bed, does not reinstall after all need not pulling down simultaneously head, breast, abdomen, lower extremity surgery display area again, complicated operation, not convenient, when especially an operation need to operate at two positions, can't be simultaneously with respect to the radiation protection at two positions, and can only divide two operations of do to realize, increased the risk of operation cost, time and operation.
(5), protective shield 1 hangs on conduit room's ceiling, make the loading and unloading of this preventer need to destroy the infrastructure such as ceiling, shipping and delivery cost is high, difficulty is large, especially,, in case position is fixed, generally be difficult to mobile this preventer to other sick beds or conduit room, in time perform the operation for meeting, certainly will need more preventer is installed, increase the equipment expenditure of hospital, and easily cause the problem of indivedual these preventer length standby time and waste hospital space resource.
