So, can guarantee to be reserved with certain space between examinating couch and the column, avoid person under inspection's lower limb or arm to be crushed by column 110 and examinating couch 200.
Consult Fig. 4, Fig. 4 is the sketch map of the X-ray detector bracing or strutting arrangement of the examinating couch of another kind of form and this utility model embodiment when being used.In the present embodiment, horizontal range between described first side and the described first side 110A is poor more than or equal to described preset distance and described second distance, and described second distance is that described bed board 210 is towards a side of described column 110 and near the horizontal range between the return pulley 220 of described column 110.That is to say:
L1≥L
safe-L2 (3)
Wherein, L1 represents the horizontal range between described first side 11 and the described first side 110A; L2 represents second distance; L
SafeThe expression preset distance.
In the present embodiment, current distance between described examinating couch 210 and the described column 110 is horizontal range and the second distance sum between first side 11 and the described first side 110A, and namely described bed board 210 can be obtained by following formula towards a side of described column 110 and the horizontal range between the described first side 110A:
L＝L14L2 (4)
Can be got by formula (3) and formula (4): L 〉=L
SafeWherein, L represents the current distance between described examinating couch 210 and the described column 110.Be that current distance between described examinating couch 210 and the described column 110 is more than or equal to preset distance.
So, can guarantee to be reserved with certain space between examinating couch and the column, avoid person under inspection's lower limb or arm to be crushed by column 110 and examinating couch 200.
Second distance be described bed board 210 towards a side of described column and near the horizontal range L2 between the return pulley 220 of described column more than or equal to 30mm and be less than or equal to 150mm.Second distance L2 is different according to the examinating couch specification, for example can be 30mm, 50mm, 80mm, 100mm, 120mm or 150mm.
Described isolation strip has second end away from first end of described column and close described column along its length.Distance between described first end and the described column is more than or equal to 100mm, and the distance between described second end and the described column is less than or equal to 70mm.That is to say that the length that is positioned at the isolation strip of described column either side is greater than or equal to 30mm, and described isolation strip be fixed in clinical in examinating couch routine corresponding position of return pulley when putting.In other embodiments, second end of described isolation strip, namely near an end of column, also can be close to described column, when failing to align with described column with the mid point of guaranteeing the examinating couch side, the return pulley of examinating couch also can with the isolation strip correspondence, and then the isolation strip can stop examinating couch and impact.
See also Fig. 5 and Fig. 6, Fig. 5 is the sketch map of an embodiment of the isolation strip of this utility model embodiment, and Fig. 6 is the A-A profile of isolation strip shown in Figure 5.In the present embodiment, described isolation strip 10A is trapezoidal perpendicular to the section of axle m2.Described first side 11 namely is trapezoidal side.When doctor or operator moved examinating couch to the X-ray detector bracing or strutting arrangement, trapezoidal first side made the return pulley bump of examinating couch produce buffering when isolating the 10A band, has avoided the person under inspection is caused excessive shock.In other embodiments, described isolation strip section perpendicular to axial direction also can be triangle or curved circular etc.
See also Fig. 7 and Fig. 8, Fig. 7 is the sketch map of another embodiment of the isolation strip of this utility model embodiment, and Fig. 8 is the B-B profile of isolation strip shown in Figure 7.In another embodiment, can be provided with lobe 12 on the described isolation strip 10B.When doctor or operator move examinating couch to the X-ray detector bracing or strutting arrangement, if the side of described isolation strip, for example the movement of examinating couch is failed to stop in the side of above-mentioned trapezoidal cross-section isolation strip, and the lobe that then is arranged on the described isolation strip can stop further that examinating couch is near column.Described lobe 12 can be salient point, also can be long rib or other shapes of projection.
Technical solutions of the utility model also provide a kind of X ray photographic equipment, comprise radiographic source and X-ray detector, and described X ray photographic equipment also comprises above-mentioned X-ray detector bracing or strutting arrangement.Described X ray photographic equipment also comprises examinating couch, the isolation strip of described X-ray detector bracing or strutting arrangement makes the distance of described examinating couch between the column of a side of described X-ray detector bracing or strutting arrangement and described X-ray detector bracing or strutting arrangement more than or equal to preset distance, avoids examinating couch and column to bump against lower limb or the arm that crushes the person under inspection.
In sum, compared with prior art, technical solutions of the utility model arrange the isolation strip so that the distance between the column of examinating couch and X-ray detector bracing or strutting arrangement is greater than or equal to preset distance in X-ray detector bracing or strutting arrangement both sides, has following advantage: when doctor or operator move examinating couch to column, if the too close column of examinating couch is its return pulley bump isolation strip then, motor pattern changes, give doctor or the clear and definite sensory feedback of operator, avoided only depending on personal experience's judgement of operator and the situation that control is difficult to guarantee the safe distance between examinating couch and the column; In addition, technical solutions of the utility model also provide the stop motion of physical means auxiliary examination bed, when the moving bed translational speed also can stop this examinating couch bump column under the situation faster, avoid X-ray detector bracing or strutting arrangement and examinating couch to damage or cause subject lesion.
More than disclose many aspects of the present utility model and embodiment, it will be understood by those skilled in the art that other side of the present utility model and embodiment.Disclosed many aspects and embodiment just are used for illustrating in this utility model, are not to be to restriction of the present utility model, and real protection domain of the present utility model and spirit should be as the criterion with claims.
