Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical equipment, and in particular to a mobile DR. Background Art
[0002] A mobile DR, also known as a mobile X-ray machine, is a medical device that emits X-rays for radiological examinations and radiotherapy of human tissue. Because it can be moved, it's convenient to use. Doctors can move it to the ward as needed to diagnose or treat patients who are less mobile.
[0003] When doctors use mobile DR to take images in a ward, because the X-rays emitted by the mobile DR are radioactive, after setting up the radiation source and the flatbed, they always move at least 10 meters away from the source to minimize the harmful effects of the X-rays. This means that for each image, the doctor must travel 20 meters back and forth, which is physically demanding for doctors who may need to image dozens of patients a day. Furthermore, since a ward is rarely home to just one patient, when one patient is being imaged by a mobile DR, other patients cannot move as flexibly as the doctor, resulting in X-rays being radiated to other patients.
[0004] Therefore, how to propose a mobile DR with protective effects so that the mobile DR does not affect the health of other patients and doctors is a technical problem that needs to be solved urgently. Summary of the Invention
[0005] The object of the present invention is to provide a mobile DR which has a protective effect and is helpful in preventing medical staff from being harmed by X-rays.

[0031] Example 1
[0032] This embodiment provides a mobile DR. The mobile DR has mobility and can be moved to different wards and floors as needed to perform imaging and diagnosis on patients who are inconvenient to move.
[0033] like Figure 1 and Figure 2As shown, the mobile DR includes a movable frame 1, an X-ray source 2, a detector, and a protective assembly. The movable frame 1 is the mounting and support structure for the entire mobile DR, and rollers are rotatably mounted on its bottom. Using rollers to move the mobile DR can reduce resistance during the entire movement process and improve the flexibility of the mobile DR during movement. Optionally, the rollers are universal wheels to improve the flexibility of the frame 1 during turns. The number of rollers can be set to multiple, such as three, four, five, or six, as needed. The multiple rollers are evenly distributed below the frame 1 to improve the stability of the frame 1 during movement.
[0034] An X-ray source 2 is mounted on a movable frame 1 and configured to emit X-rays. A detector is disposed opposite the X-ray source 2 and configured to receive the X-rays. The specific structures of the X-ray source 2 and the detector are conventional and will not be described in detail herein.
[0035] The protective component is mainly used to isolate X-rays to prevent X-rays from irradiating other patients or medical staff except the target patient. Figure 1 and Figure 2 As shown, the protective assembly includes a protective plate 3 and a drive mechanism. Optionally, the protective plate 3 is a lead plate, which can effectively block X-rays. Of course, in addition to lead plates, other materials that can block X-rays can also be used as the material for the protective plate 3, and these are not listed here. In this embodiment, the protective plate 3 is a transparent, light-transmitting lead plate to improve visibility.
[0036] When the X-ray source 2 emits X-rays to film a target patient, the drive mechanism drives the shield 3 to move around the X-ray source 2 and detector to block the X-rays, thereby isolating the X-rays from medical staff and other patients, preventing them from being harmed by the X-rays. After the filming is complete, the drive mechanism drives the shield 3 to reposition itself to prevent it from interfering with the flexible movement of the mobile DR. Furthermore, the repositionable shield 3 reduces the likelihood of damage during the movement of the mobile DR.
[0037] Optionally, in this embodiment, the drive mechanism may be a lifting drive mechanism that drives the protective plate 3 to rise and fall along the height direction of the mobile DR, thereby achieving X-ray isolation. Specifically, in this embodiment, the lifting drive mechanism includes a gear and a linear rack that mesh with each other. The linear rack is connected to the protective plate 3 and is disposed along the height direction of the mobile DR. The gear can rotate under the action of an external force and drives the linear rack to rise and fall along the height direction of the mobile DR.
[0038] Furthermore, a crank handle can be provided at the center of the gear, with one end of the crank handle connected to the center of the gear. During use, manually rotating the other end of the crank handle can drive the gear to rotate, thereby driving the linear rack and protective plate 3 to move vertically up and down. Optionally, the crank handle can be shaped like a "Z" or "L" to facilitate force application by medical personnel.
[0039] In addition to placing a crank handle at the center of the gear, a motor can also be placed at the center of the gear, with the motor shaft connected to the center of the gear. The motor can automatically rotate the gear and automatically raise and lower the linear rack and protective plate 3. Compared to using a crank handle, using a motor offers a higher degree of automation and helps reduce the workload of medical staff. In addition to the above structure, other structures that can serve as lifting drive mechanisms are also applicable to this embodiment, such as the window lift mechanism on existing automobiles.
[0040] The protective plate 3 can be composed of a single plate or a plurality of plates stacked together. In order to take into account both the protective effect and the storage capacity of the mobile DR, the protective plate 3 is configured to be a plurality of plates stacked together. Specifically, in the present embodiment, there are two protective plates 3, and the two protective plates 3 are a fixed protective plate 301 and a movable protective plate 302. The fixed protective plate 301 is fixedly arranged on the movable frame 1, and the movable protective plate 302 is slidably connected to the fixed protective plate 301. In the present embodiment, the fixed protective plate 301 and the movable protective plate 302 can be flat lead plates or curved lead plates.
[0041] When the X-ray source 2 does not emit X-rays, the initial positions of the fixed shielding plate 301 and the movable shielding plate 302 are as follows: Figure 1 As shown, the overlapping is arranged at the bottom of the frame 1. When the X-ray source 2 needs to radiate X-rays, the movable protective plate 302 moves upward under the drive of the driving mechanism, thereby achieving the following Figure 2 Of course, in other embodiments, the fixed protection plate 301 can also be set on the upper part of the frame 1, and the movable protection plate 302 can be moved from top to bottom to achieve protection.
[0042] Furthermore, in order to facilitate medical staff to observe the working status of the mobile DR, a visual area is provided on the protective plate 3, through which medical staff can carefully observe the mobile DR so as to grasp the working status of the mobile DR in a timely manner.
[0043] Optionally, the technical features mentioned in this application may be provided to accessories of the mobile DR rather than the mobile DR itself. For example, the mobile DR may be equipped with a lead glass trolley with an automatic following function, and the protective component is provided on the lead glass trolley. The lead glass trolley is specially provided with a protective plate 3, and the protective plate 3 is liftable. By providing the lead glass trolley with an automatic following function, the location of the protective component can be selected very flexibly, thereby being able to better and more comprehensively protect the operating doctor or the patient next door. The lead glass trolley that reaches the target position can be locked, so that the radiation protection of the mobile DR reaches a state similar to that of a fixed DR, reducing unnecessary X-ray radiation exposure to people other than the patient.
[0044] Example 2
[0045] This embodiment provides a mobile DR that is substantially identical to the mobile DR in Example 1, differing only in the structure of its drive mechanism. In this embodiment, the mobile DR employs a rotary drive mechanism capable of driving the protective plate 3 along the circumference of the mobile DR, thereby enabling the protective plate 3 to transition between a protective state and a stowed state. Specifically, the rotary drive mechanism comprises a gear and an arcuate rack. The arcuate rack is connected to the protective plate 3 and arranged around the circumference of the mobile DR. The gear is configured to rotate, driving the arcuate rack to rotate along the circumference of the mobile DR.
[0046] In order to drive the gear to rotate, a crank can be set at the center of the gear, and one end of the crank can be connected to the center of the gear. When in use, the gear can be driven to rotate by manually rotating the other end of the crank, thereby driving the arc-shaped rack and the protective plate 3 to move circumferentially around the mobile DR. Of course, in addition to setting the crank at the center of the gear, a motor can also be set at the center of the gear, and the motor shaft of the motor can be connected to the center of the gear. By using the motor, the automatic rotation of the gear and the automatic horizontal movement of the arc-shaped rack and the protective plate 3 can be achieved. Compared with using a crank, using a motor has a high degree of automation and is conducive to reducing the workload of medical staff.
[0047] Of course, in this embodiment, the protective plate 3 can be composed of a single plate or a plurality of plates stacked together. In order to balance the protective effect and storage, the protective plate 3 is configured to be a plurality of plates stacked together. Specifically, in this embodiment, there are two protective plates 3, namely a fixed protective plate 301 and a movable protective plate 302. The fixed protective plate 301 is fixedly mounted on the movable frame 1, and the movable protective plate 302 is slidably connected to the fixed protective plate 301. In this embodiment, both the fixed protective plate 301 and the movable protective plate 302 are curved plates.
[0048] When the X-ray source 2 is not emitting X-rays, the fixed shield 301 and the movable shield 302 are arranged overlappingly on the right side of the bottom of the gantry 1. When the X-ray source 2 needs to emit X-rays, the movable shield 302 is driven to the left by the drive mechanism, thereby reaching a shielding state for protection. Of course, in other embodiments, the fixed shield 301 can also be arranged on the left side of the gantry 1, and the movable shield 302 can be moved horizontally from left to right to achieve a protective effect.
[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
