Description

Apparatus for radiation shielding

The present invention relates to a radiation shielding device.

In general, when using a radiation device, only a patient is located in an imaging room, but a medical practitioner closely adheres to the patient's side during fluoroscopy to perform medical treatment.

Radiation scattered in all directions occurs during fluoroscopy, and radiation exposure occurs in all areas in the fluoroscopic imaging room. Radiation to be covered is radiation (out-of-focus radiation, leakage radiation) generated in a direction other than the intended direction for fluoroscopy of the patient (double-dotted line shown in FIG. 1) Scattered radiation scattered around the patient (shown in FIG. 1) dotted line). Scattered radiation is the biggest cause of exposure of medical personnel rather than out-of-focus radiation and leakage radiation.

The base 10 supports the radiation shielding device 1 and makes it movable. A plurality of wheels 11 are coupled to the lower surface of the base 10, and the base 10 when viewed from a plan has a digut shape. Accordingly, one side of the base 10 is open, and the base 10 may be located under the bed of the fluoroscopic imaging device. At this time, the base 10 may be positioned around the pillar supporting the bed of the fluoroscopic imaging device.

On the other hand, the wheel 11 is provided with a locking device (not shown). By locking the locking device, the radiation shielding device 1 is fixed in the installation position and does not move.

The vertical frame unit 20 adjusts the vertical height of the radiation shielding device 1 . Accordingly, the vertical frame part 20 is vertically disposed upward from the upper surface of the other side of the base 10 . The vertical frame 20 is adjustable in length by combining bar members having different diameters. The bar members are slide-coupled to each other. The bar members whose length is adjusted by sliding may be fixed through a pin member. The length of the vertical frame portion 20 may vary depending on the position of the bed from the ground. Here, the upper end of the vertical frame part 20 is positioned higher than the bed with respect to the ground.

On the other hand, the vertical frame portion 20 may include an electric cylinder or the like. The length of the vertical frame part 20 can be adjusted by sliding the bar members using an electric cylinder.

The frame part 30 faces the base 10 at a distance from the top of the base 10 and can be length-adjusted along the length direction of the bed of the fluoroscopic imaging device. Accordingly, the frame part 30 can be adjusted in length according to the patient's body and the target area for photographing.

When the base 10 is located under the bed, the frame part 30 faces the base 10 with the bed interposed therebetween.

The frame part 30 includes a horizontal bar 31 and a variable bar 32 .

The horizontal bar 31 is disposed on the upper end of the vertical frame portion 20 to form a right angle with the vertical frame portion (20). A central portion of the horizontal bar 31 is connected to the vertical frame portion 20 . Accordingly, the horizontal bar 31 extends in the left and right directions with respect to the vertical frame portion 20 .

The variable bar 32 is disposed at both ends of the horizontal bar 31 , and the length is adjustable. The variable bar 32 includes a rail guide 321 and a slide bar 322 .

The rail guide 321 has a predetermined length. The rail guide 321 is disposed in one direction at both ends of the horizontal bar 31, and rail grooves 321a are formed along the longitudinal direction.

One end of the slide bar 322 is inserted into the rail groove 321a, and the other end is exposed to the outside of the rail guide 321 . Here, the length of the slide bar 322 is longer than the length of the rail guide 321 . The length of the variable bar 32 may be varied according to the slide of the slide bar 322 . The length of the variable bar 32 increases as the slide bar 322 is pulled out from the fully inserted state (refer to FIGS. 2 and 3 ) in the variable bar 32 . Accordingly, the length of the frame part 30 increases (see FIGS. 5 and 6).

Conversely, as the drawn out variable bar 32 is inserted into the slide bar 322 , the length of the variable bar 32 becomes shorter.

Next, another embodiment of the frame part will be described with reference to FIGS. 7 and 9 .

The frame part according to this embodiment includes the horizontal bar 31 according to the embodiment of FIGS. 2 to 6 as it is, while the variable bar 32a includes a variable support bar 323 and an exposed bar 324 .

The variable support bar 323 has an inside penetrated along the longitudinal direction, and locking protrusions 323a are formed at both ends. The variable support bar 323 consists of a plurality, and the variable support bar 323 located at one side is coupled to the horizontal bar 31 .

The exposed bar 324 has a predetermined length and connects the adjacent variable support bars 323 . The exposed bar 324 is inserted into the variable support bar 323 . The exposed bar 324 may slide on the variable support bar 323 . One end of the exposed bar 324 is located inside the one side variable support bar 323 , and the other end is located inside the other side variable support bar 323 . At both ends of the exposed bar 324, stepped 324a caught on the stopping jaw 323a are formed. The exposed bar 324 is not separated from the variable support bar 323 while the stepped 324a is caught on the engaging jaw 323a.

As the exposed bar 324 is drawn out from the variable support bar 323, the interval between the adjacent variable support bars 323 is widened, and the length of the frame part 30 is increased as shown in FIG. 9 .

Next, another embodiment of the frame part will be described with reference to FIG. 10 .

Referring to FIG. 10 , the frame part 30 according to this embodiment further includes a horizontal frame 33 while including the frame part 30 according to the embodiments of FIGS. 2 to 9 as it is.

The horizontal bar 31 of the frame part 30 according to this embodiment is separated from the vertical frame part 20 and the horizontal frame 33 connects the horizontal bar 31 and the vertical frame part 20 . The horizontal frame part 33 has a structure in which the length can be adjusted in the same way as the vertical frame part 20 . Accordingly, the frame portion 30 can be adjusted in length along the longitudinal direction of the bed through the horizontal frame 33 and the variable bars 32 and 32a.

Referring back to FIGS. 2 and 5 , the shielding part 40 is installed in the frame part 30 to minimize radiation exposure of patients and medical personnel. The shielding part 40 includes a variable length fiber 41 , a vertical fiber 42 , and a see-through panel 43 .

The variable-length fiber 41 is located on the upper surface and the side surface of one side of the frame part 30 in a corrugated form to cover the upper surface, and hangs down from the side surface. As shown in FIG. 5 , the variable-length fiber 41 may be spread along the stretched frame part 30 as the wrinkled portion is expanded when the length of the frame part 30 is increased.

The vertical fibers 42 have a predetermined width and are disposed on the other side of the frame part 30 . At this time, the adjacent vertical fibers 42 maintain an overlapping state with each other. A medical practitioner may treat/operate a patient with a gap between the adjacent vertical fibers 42 . Conversely, the patient may expose the body between adjacent vertical fibers 42 . In addition, since the adjacent vertical fibers 42 maintain an overlapping state with each other, radiation emitted between the adjacent vertical fibers 42 can be effectively shielded.

Such variable length fibers 41 and vertical fibers 42 can be spread down or rolled up, so there is no obstacle to installation due to the fluoroscopic imaging device and the patient's body.

In addition, as the variable length fiber 41 and the vertical fiber 42 take the form that is spread down from the side of the frame part 30, the scattering rays generated from the patient, up to the position of the X-ray generating part (X-ray tube) It is formed to be long and can shield radiation leaking from the X-ray generator.

The see-through panel 43 is disposed on the upper surface of the other side of the frame part 30 and is formed to be transparent so that the condition of the patient can be checked. This makes it easy to check the patient's condition during fluoroscopy and to take immediate action in case of emergency. In addition, without removing the radiation shielding device 1 from the fluoroscopic imaging device, the operation/surgery can be performed while observing the patient's condition through the fluoroscopic panel 43 .

The variable length fiber 41, the vertical fiber 42, and the see-through panel 43 include lead to shield radiation. The see-through panel 43 may include lead glass, lead acrylic, and the like.

Next, an operation of the radiation shielding device described above will be described with reference to FIG. 11 .

Referring to FIG. 11 , the radiation shielding device 1 is positioned on one side and the other side of the bed of the fluoroscopic imaging device during fluoroscopy, respectively. Cover the patient with the radiation shielding devices (1) located on both sides of the bed except for the area for fluoroscopy. The length of the frame part 30 is adjusted in a state where the support bar 325 of the frame part 30 (refer to FIGS. 2 and 5) is positioned on the bed. The frame portion 30, the length of which is increased by the support of the support bar 325, does not sag. By adjusting the length of the frame part 30 , the shielding part 40 performs fluoroscopy in a state in which a portion other than the target area for fluoroscopy is covered.

The radiation irradiated to the patient is irradiated toward the target area for imaging, and the portion other than the target area is blocked by contacting the outer surface of the shielding unit 40 . Therefore, the patient can shield the radiation directed to the area other than the target area, which is effective in reducing the patient's exposure dose. In addition, when scattered radiation scattered from the patient to the surroundings comes into contact with the inner surface of the shielding unit 40, it is blocked. Accordingly, it is possible to prevent the medical personnel from being exposed to the scattered radiation.

In addition, since the shielding unit 40 covers all portions except for the fluoroscopic imaging target portion, it is possible to shield radiation scattered in all directions. The radiation shielding device 1 can be used without additional modification of the fluoroscopic imaging device by the movable base 10 and the adjustable length frame 30 .

As the radiation shielding device 1 wraps around the patient, the medical personnel can minimize the wearing of the protective clothing. Accordingly, it is possible to reduce the fatigue of the medical personnel due to the weight of the protective suit.
