Description

Protective case of digital X-ray detector

The present invention relates to a protective case of a digital X-ray detector capable of protecting the digital X-ray detector from external shocks and the like.

The diagnostic X-ray imaging system used in the conventional medical uses a film to photograph a subject and prints the film for reading to obtain an image. Recently, a digital x-ray detector for obtaining a digital image using a thin film transistor (TFT) without a film has been researched and developed.

A digital X-ray detector is formed on a thin film transistor array panel, an X-ray reaction layer of amorphous selenium stacked on top of the thin film transistor array panel, and on top of the X-ray reaction layer. It is configured to include a top electrode.

When X-rays are irradiated to the digital X-ray detector, the X-rays create electron-hole pairs in the X-ray reaction layer. The electron-hole pair is accelerated by the voltage applied to the top electrode so that the electrons move to the external electrode, and the holes are charged to the capacitor of the TFT through the upper electrode of the TFT. When the charged voltage is transferred to the image processing apparatus by the switching operation of the TFT, the image processing apparatus acquires the X-ray detection image.

Internal components of such digital X-ray detectors, such as X-ray reaction layers, thin film transistor array panels, are susceptible to damage from external forces. Since digital X-ray detectors are frequently used outside of X-ray imaging systems, they are more likely to be exposed to external forces.

For example, there may be a case where the digital X-ray detector falls and is shocked while moving or in use, or is shocked from the outside. In this case, internal components of the digital X-ray detector may be damaged, and a problem may occur in which the performance of the digital X-ray detector is degraded.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to protect the digital X-ray detector from external shock, and to provide a protective case of the digital X-ray detector that can facilitate the installation of the digital X-ray detector. In providing.

According to the present invention, when the digital X-ray detector is mounted on the protective case, while being moved or in use, the shock amount transmitted to the digital X-ray detector while absorbing most of the external shock is absorbed by the protective case even if it falls or receives an external shock. Can be minimized. Therefore, the problem that the internal components of the digital X-ray detector are damaged by the impact can be prevented, and the problem that the performance of the digital X-ray detector is degraded by the impact can be prevented.

Further, according to the present invention, the case body is covered from the top of the digital X-ray detector by holding the digital X-ray detector after the digital X-ray detector is covered without leaving the digital X-ray detector completely raised. Can be installed. Therefore, not only the process of mounting the digital X-ray detector on the case body can be simplified, but the fall accident of the digital X-ray detector can be prevented.

The case body 110 detects the digital X-ray detector 10 to cover at least a portion of the circumference of the digital X-ray detector 10 while covering the detection surface of the digital X-ray detector 10 or the opposite side thereof. The receiving groove 111 is recessed in a surface facing the surface or the opposite surface. Accordingly, in the state where the digital X-ray detector 10 is accommodated in the accommodation groove 111, the detection surface of the digital X-ray detector 10 or the opposite side thereof is covered by the bottom surface of the accommodation groove 111, and the digital The circumferential surface of the X-ray detector 10 is at least partially wrapped by the sidewall of the receiving groove 111 to be protected.

The case body 110 may be made of polycarbonate, carbon fiber, acrylic, tempered plastic, glass, or the like having excellent impact resistance. Accordingly, the case body 110 may increase the effect of protecting the digital X-ray detector 10 from external shock in a state in which the digital X-ray detector 10 is accommodated.

The locking mechanism 120 locks or unlocks the digital X-ray detector 10 in a state where the digital X-ray detector 10 is accommodated in the accommodation groove 111 of the case body 110. Is installed on. The digital X-ray detector 10 may be held and used in the case body 110 while being locked to the case body 110 by the locking mechanism 120, and may be accommodated in the case body 110. In the process of moving to the departure from the case body 110 can be prevented. When the digital X-ray detector 10 is to be detached in the state accommodated in the case body 110, the digital X-ray detector 10 may be unlocked from the state in which the digital X-ray detector 10 is locked to the case body 110 by the locking mechanism 120.

As described above, the digital X-ray detector 10 is covered by the case body 110 and at least partially wrapped and accommodated, and then locked and mounted to the case body 110. Accordingly, when the digital X-ray detector 10 is moved or in use while being mounted on the case body 110, the external shock is mostly absorbed by the case body 110 while being dropped or subjected to external shock, and thus the digital X-ray detector 10 is absorbed by the case. The amount of impact delivered to the line detector 10 can be minimized. Therefore, the problem that the internal components of the digital X-ray detector 10 are damaged by the impact can be prevented, and the problem that the performance of the digital X-ray detector 10 is degraded by the impact can be prevented. .

In addition, the digital X-ray detector 10 is placed on the floor or the like, and the case body 110 is covered from the top of the digital X-ray detector 10 to accommodate the digital X-ray detector 10 and then locked. I can attach it by processing. Accordingly, the user does not need to lift the digital X-ray detector 10 completely in order to mount the digital X-ray detector 10 to the case body 110. Therefore, the process of mounting the digital X-ray detector 10 to the case body 110 may be simplified, and the fall accident of the digital X-ray detector 10 may be prevented.

On the other hand, gripping grooves 112 are formed on both sides of the case body 110, and the user covers the digital X-ray detector 10 while holding the case body 110 by holding a finger on the gripping groove 112. Or to separate it from the digital X-ray detector 10. In addition, the case body 110 may further include a handle 113 to be gripped by the user. Accordingly, the user can conveniently carry the case body 110 in the empty state or the state in which the digital X-ray detector 10 is mounted while holding the handle 113.

The handle 113 may be formed at one side of the case body 110. In this case, as shown in Figure 2, the side of the case body 110, the handle 113 is formed, as shown in Figure 2, the case body 110 is attached to the footrest 114 that can act as a buffer when placed on the floor Can be. The footrest 114 may be made of a material such as urethane.

As shown in FIG. 4, the digital X-ray detector 10 may be accommodated in the accommodation groove 111 while being in close contact with the bottom surface of the accommodation groove 111. As another example, as shown in FIG. 5, the digital X-ray detector 10 may be accommodated in the accommodating groove 111 while maintaining a gap of a predetermined distance from the bottom of the accommodating groove 111. The gap between the bottom surface of the accommodating groove 111 and the digital X-ray detector 10 acts as a buffer space, so that an external shock is applied to the case body 110 to the digital X-ray detector 10. The effect of reducing can be further enhanced.

A supporting jaw 115 is formed in the accommodating groove 111 to support the digital X-ray detector 10 while maintaining a gap at a constant distance from the bottom surface of the accommodating groove 111. The support jaw 115 may protrude from the inner wall of the accommodation groove 111 into the accommodation groove 111 by a predetermined length. The support jaw 115 may be formed continuously or intermittently along the inner wall circumference of the receiving groove 111.

The shock absorbing member 130 may be further installed in the accommodation groove 111. When the external shock is applied to the case body 110 while the digital X-ray detector 10 is accommodated in the accommodating groove 111, the shock absorbing member 130 may transmit an impact transmitted to the digital X-ray detector 10. It can be absorbed. The shock absorbing member 130 may be made of a cushioning material such as sponge or rubber. As illustrated in FIG. 4, the shock absorbing member 130 may be disposed at a portion of the receiving groove 111 that is in contact with the edge of the digital X-ray detector 10. When the support jaw 115 is formed in the accommodation groove 111, as shown in FIG. 5, the shock absorbing member 130 may have the digital X-ray detector 10 in the support jaw 115 and the accommodation groove 111. It may be disposed at a portion in contact with the.

Meanwhile, the locking mechanism 120 may include a latch member 121 and a latch fixing mechanism 126. The latch member 121 includes a case for locking the outer surface of the digital X-ray detector 10 by the digital X-ray detector 10 and being released from the gun state while the digital X-ray detector 10 is accommodated in the receiving groove 111. The main body 110 is supported to be movable.

For example, referring to FIGS. 6 to 9 together, the latch member 121 is supported by the case body 110 such that the latching portion 122 slides in a direction parallel to the outer surface of the digital X-ray detector 10. Can be. When the locking portion 122 slides to the locked position to be located on the outer surface of the digital X-ray detector 10, the digital X-ray detector 10 is locked, and the outside of the digital X-ray detector 10 is moved. Sliding to the unlocked position away from the side surface can release the digital X-ray detector 10 from the locked state.

The latch member 121 may be provided in plurality so that the digital X-ray detector 10 may be stably locked in the state accommodated in the case body 110. For example, the four latch members 121 may be disposed one at both edges of one side of the case body 110 and at both edges of the opposite side thereof.

As another example, although not shown, the latch member 121 may be rotatably supported by the case body 110. Here, when the latch member 121 is rotated so as to be positioned on the outer surface of the digital X-ray detector 10, the digital X-ray detector 10 is locked, and the outer side of the digital X-ray detector 10 is disposed. Rotational movement away from the plane can release the digital X-ray detector 10 from the locked state.

The latch fixing mechanism 126 is for fixing the latch member 121 in a state where the latch member 121 is moved to the locked position to hook the outer surface of the digital X-ray detector 10. The latch lock mechanism 126 may be configured in various ways to secure the latch member 121 in the locked position.

For example, the latch fixing mechanism 126 may include a rod member 127, a guide member 128, and an elastic member 129. Here, the rod member 127 includes a rod body 127a fixed to the latch member 121 by a screw member, and a rod 127b protruding from the rod body 127a.

The guide member 128 includes a guide body 128a fixed to the case body 110 by a screw member, and a guide hole 128b formed to guide the slide movement of the rod 127b while the rod 127b is fitted. Include. Rails are formed on both sides of the guide body 128a, and guide jaws supporting the rails are formed inside the latch member 121, so that the latch member 121 can be slidably moved.

Then, the fixing jaw 128c is formed on the guide body 128a. The fixing jaw 128c allows the latch member 121 to be fixed in a state in which the latch member 121 slides to the locked position. The elastic member 129 applies an elastic force between the rod 127b and the guide body 128a to keep the latch member 121 fixed in the locked position. The elastic member 129 is elastically deformed by the user when the latch member 121 moves from the locked position out of the fixed jaw 128c to the unlocked position. When the force applied to the latch member 121 is removed, the elastic member 129 is removed by the restoring force. The latch member 121 can be fixed beyond the fixing jaw while automatically moving to the locked position. The elastic member 129 may use a compression coil spring.

When the case body 110 mounted with the digital X-ray detector 10 is subjected to a normal level of impact during movement or use, the clamping force of the latch member 121 causes the digital X-ray detector 10 to have a case body ( 110 may be set so as not to be separated. If a large impact is applied to the case main body 110 on which the digital X-ray detector 10 is mounted due to a drop, the clamping force of the latch member 121 may cause the digital X-ray detector 10 to be inserted into the case main body 110. It can be set to minimize the impact received by the digital X-ray detector 10 while being separated from it.

The locking mechanism 120 may further include a fixing holder 123 as shown in FIG. 3. In this case, some of the latch members 121 may be replaced with the fixed holder 123. For example, the two latch members 121 disposed at both edges of one side of the case body 110 may be replaced with two fixing holders 123. The fixed holder 123 receives the accommodating groove 111 from the case body 110 so that the outer surface of the digital X-ray detector 10 is caught while the digital X-ray detector 10 is accommodated in the accommodating groove 111. It has a structure formed to protrude into the entrance of the.

As shown in FIG. 10, each inner surface of the latch member 121 and the fixed holder 123 has the digital X-ray detector 10 with the digital X-ray detector 10 accommodated in the receiving groove 111. It can be formed in a shape that can support the periphery of the digital X-ray detector 10 to fit the periphery of the. For example, when the circumference of the digital X-ray detector 10 is a convex curved shape, each inner surface of the latch member 121 and the fixed holder 123 is at least partially adapted to the circumference of the digital X-ray detector 10. It may be made in the shape of a concave curved surface. Accordingly, in the state where the digital X-ray detector 10 is accommodated in the accommodating groove 111, the digital X-ray detector 10 may be stably supported without being shaken in parallel with the bottom surface of the accommodating groove 111.

As shown in FIG. 11, in the receiving groove 111, the digital X-ray detector 10 guides the reception of the digital X-ray detector 10 when the digital X-ray detector 10 is accommodated in the receiving groove 111. An elastic guide 140 may be installed to elastically support the circumference of the detector 10. Accordingly, when the user places the case body 110 on the upper portion of the digital X-ray detector 10 and presses the case body 110, the digital X-ray detector 10 guides the elastic guide 140. Received can be accommodated smoothly in the receiving groove 111 at a time. Thus, the acceptance process of the digital X-ray detector 10 can be convenient. The elastic guide 140 may be installed along the inner wall of the receiving groove 111, and may be formed of a leaf spring having a curved surface that is convex toward the circumference of the digital X-ray detector 10.

On the other hand, as shown in Figure 12 and 13, the protective case 100 may further include a grid member 150 that is detachably installed on the outer surface of the case body (110). The grid member 150 prevents X-ray scattering when photographing a subject while the digital X-ray detector 10 is accommodated in the accommodation groove 111, thereby preventing the image of the image photographed by the digital X-ray detector 10. To increase the sharpness. That is, when photographing a thick area such as the chest or abdomen of the subject, X-rays are scattered to reach the digital X-ray detector 10, and the grid member 150 is used to eliminate such scattering.

For example, the grid member 150 may include a grid 151 and a grid 151 disposed on an outer surface of the case body 110 that covers the detection surface of the digital X-ray detector 10 or the opposite surface thereof. The frame 152 formed at the circumference and the grid member 150 may include an attachment / detachment mechanism 153 for attaching or detaching the outer surface of the case body 110.

The frame 152 is formed in a shape that can surround the circumferential surface of the case body 110. The attachment and detachment mechanism 153 includes a locking ring 154 and a fixing lever 155. The hook ring 154 has a structure protruding from the frame 152 to the inside of the case body 110 so as to hook the case body 110 in a state in which the grid member 150 is mounted to the case body 110.

The fixed lever 155 is slidably mounted to the frame 152 to lock or unlock the grid member 150 while the grid member 150 is mounted to the case body 110. The fixing lever 155 is provided with a fixing protrusion. The fixing protrusion locks the grid member 150 when moved to fit into the fixing groove of the case body 110 or the handle 113, and when the movement is separated from the fixing groove, the grid member 150 is released from the locked state. can do. The fixing lever 155 may be fixed by the lever fixing mechanism in a state in which the grid member 150 is locked. The lever lock mechanism may be configured in the same manner as the latch lock mechanism 126.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Could be. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
