Description

Technical Field

[0001] The utility model relates to a radiation protection device, in particular to an X-ray machine film protection screen. Background Art

[0002] The principle of X-ray filming is based on the penetration of X-rays, fluorescence effect and photosensitivity effect, and uses the differences in density and thickness between human tissues to form images. When X-rays pass through different tissue structures of the human body, they are absorbed to different degrees, and the amount of X-rays reaching the screen or film is different, so that images with different light and dark or black and white contrasts are formed on the screen or X-ray film. Although X-ray filming technology has been optimized and the intensity of X-ray exposure has been reduced to the minimum when taking X-rays, it is inevitable that the rays will penetrate the human body and cause harm to the human body. For this reason, a radiographing stand is needed for corresponding protection. The existing radiographing stand mainly includes a movable bracket and a lead plate. Before taking an X-ray, the patient moves the radiographing stand behind him to block the parts that do not need to be irradiated. However, the existing radiographing stand has a simple and heavy structure. When each patient comes to take an X-ray, medical staff needs to come out of the operating room to adjust according to the part that the patient needs to take a picture, which is not only inefficient but also labor-intensive. Utility Model Content

[0003] The utility model aims to provide an X-ray machine film protection screen to solve the problem that the original protection screen is difficult to push due to its weight and requires medical staff to run back and forth out of the studio for adjustment.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An X-ray machine film protection screen, comprising

[0006] The pivot mechanism is arranged on the side of the film stand;

[0007] A protective screen mechanism is connected to the pivot mechanism, and is placed between the patient and the X-ray machine during filming to leave a space for filming;

[0008] The protective screen mechanism includes a frame connected to a pivot mechanism, and lead plate groups that can be vertically extended and retracted are symmetrically arranged on the upper and lower sides of the frame, and a filming gap is left between the two groups of lead plates. A traction motor is mounted above the frame, and a traction rope is wound on the output shaft of the traction motor. The traction rope is respectively connected to the lower part of the lead plate group at the top and the upper part of the lead plate group at the bottom, and the traction motor is wirelessly connected to a remote control.

[0009] Preferably, the lead plate group includes a plurality of overlapping lead plates having an I-shaped cross-section, and the frame includes two horizontal frames arranged horizontally and two vertical frames arranged vertically. The vertical frames are vertically provided with guide grooves the same number as the lead plates in the lead plate group, and both ends of the lead plates can be vertically slid into the guide grooves.

[0010] Preferably, the protective screen mechanism also includes an adjusting motor, which is fixedly mounted on the upper part of the lower lead plate group, and the lower end of the traction rope is wound around the output shaft of the adjusting motor, and the adjusting motor is wirelessly connected to a remote control.

[0011] Preferably, the horizontal frame of the frame is in an arc shape, and the lead plate group is in an arc shape concentric with the horizontal frame.

[0012] Preferably, the pivot mechanism includes a pivot motor disposed on a side of the radiographic frame, the pivot motor is electrically connected to a foot switch, an output shaft of the pivot motor is coaxially connected to a vertically extending rotating shaft, and the frame is connected to the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. This solution is set up next to the radiograph stand. When the patient takes an X-ray, he only needs to start the pivot mechanism after standing still to complete the shielding of the protective screen mechanism behind him. After the patient is shielded, the medical staff can drive the traction motor to rotate through the remote control. As the traction motor rotates, the telescopic state of the two sets of lead plates can be easily adjusted to complete the up and down adjustment of the radiograph gap, which is convenient and quick.

[0015] 2. After the I-shaped lead plates overlap, one lead plate can be lifted or lowered to the upper or lower edge of the adjacent lead plate, which can drive the synchronous lifting or lowering of the lead plate, thereby achieving the synchronous extension and retraction of the upper and lower lead plate groups.

[0016] 3. By adjusting the individual rotation of the motor, the length of the traction rope between the two groups of lead plates can be changed, thereby changing the size of the gap between the two groups of lead plates, ensuring that the gap can be controlled at the most appropriate size when taking X-rays of patients to avoid excessive exposure of patients.

[0017] 4. The arc-shaped lead plate group can better protect the patient's body.

[0018] 5. The pivot mechanism is controlled by a foot switch, which is convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figures 1 to 3 The protective screen for X-ray machine shown in the figure comprises a pivot mechanism 200 and a protective screen mechanism 100. The pivot mechanism is arranged beside the film frame 300, and the protective screen mechanism is installed on the pivot mechanism 200, so as to be turned over under the drive of the pivot mechanism and shielded between the patient and the X-ray machine when the X-ray film is taken. It should be noted that the protective screen mechanism has a gap for the X-rays emitted by the X-ray machine to irradiate the patient's body.

[0027] Specifically, the protective screen mechanism 100 includes a frame 110 fixedly mounted on a pivot, the frame is a rectangular structure, and a group of lead plate groups 120 are symmetrically arranged on the upper and lower sides of the frame, the lead plate groups can be vertically extended, and a gap is left between the two groups of lead plate groups for X-rays to pass through. It should be noted that a traction motor 130 is set above the frame. Preferably, the traction motor is a double-axis motor, and a traction rope 140 is respectively wound on the two rotating shafts of the motor, and the traction rope is suspended downward and connected to the lower part of the upper lead plate group and the upper part of the lower lead plate group. When it is necessary to control the lifting and lowering of the two groups of lead plate groups 120, the traction rope is driven to rotate, and as the traction motor rotates, the traction rope is reeled or unreeled, and as the traction rope is reeled or unreeled, the two groups of lead plate groups are coordinated to retract and retract. It should also be noted that in order to facilitate the control of medical staff, the traction motor is wirelessly connected to a remote controller 160 that can control its forward and reverse reeling.

[0028] As a further improvement of the above-mentioned embodiment, the lead plate group is composed of several pieces of lead plates 121 with an "I"-shaped cross section, and adjacent lead plates overlap each other so that the restrictions between adjacent lead plates can be realized through the protruding edges at both ends when the lead plates are stretched up and down. In order to prevent the lead plate group from spreading out, the frame 110 matched therewith includes two horizontal frames 111 arranged horizontally and two vertical frames 112 arranged vertically. The four frames are connected end to end to form a frame with a rectangular projection surface. On the vertical frame, several guide grooves 113 extending along the length direction of the vertical frame are provided, and the two ends of the lead plate are slidably matched and plugged into the guide grooves to slide up and down in the guide grooves. The traction line is respectively connected to the lowest lead plate of the upper lead plate group and the top lead plate of the lower lead plate group.

[0029] In addition, it should be noted that the size of the area required for filming of each patient is different. In order to allow the X-ray to irradiate only the position where the X-ray film is required, the protective screen mechanism 100 also includes an adjusting motor 150, which is fixedly installed on the upper part of the lead plate group below. Specifically, the adjusting motor is located on a lead plate 121 placed on the upper part of the lead plate group below. At the same time, the lower end of the traction rope 140 is wound on the output shaft of the adjusting motor. The length of the traction rope between the upper and lower lead plate groups is controlled by driving the adjusting motor to rotate forward and backward. It should be noted that for the convenience of control, the adjusting motor is wirelessly connected to the remote control.

[0030] It should also be noted that in order to protect the patient's parts that do not need to be irradiated with X-rays as much as possible, the horizontal frame 111 in the frame 110 is an arc-shaped structure. In conjunction with this, the lead plate group is an arc-shaped structure concentric with the horizontal frame 111, that is, each lead plate is concentric with the arc-shaped horizontal frame. After the protective screen mechanism is turned over, other parts of the patient can be shielded as much as possible.

[0031] In addition, it should be noted that in order to control the rotation of the protective screen mechanism after the patient stands still, the pivot mechanism 200 includes a pivot motor 210 buried under the ground, a rotating shaft 220 is coaxially connected to the output shaft of the pivot motor, and the support block of the protective screen mechanism is fixedly mounted on the rotating shaft. At the same time, a foot switch 230 is also provided at the position where the patient's sole reaches, and the foot switch is electrically connected to the pivot motor to conveniently drive the pivot motor to rotate.

[0032] Working principle: When a patient needs to take an X-ray, the patient first stands in front of the X-ray stand, then steps on the foot switch to drive the pivot mechanism to rotate. As the pivot mechanism rotates, the protective screen mechanism flips to between the X-ray machine and the patient to shield the patient. During this period, the medical staff controls the extension and retraction of the adapter wires of the two sets of lead plates through the remote control, so that the gap between the two sets of lead plates is facing the position where the patient needs to be exposed to X-rays. During this period, the medical staff can also control the forward and reverse rotation of the motor through the remote control to adjust the gap between the upper and lower sets of lead plates, so as to minimize the possibility of unnecessary areas of the patient being exposed to X-rays.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
