Description

Technical Field

[0001] The utility model belongs to the field of protective measures for X-ray equipment, and in particular relates to a protective device for mobile X-ray equipment. Background Art

[0002] Mobile DR (mobile digital X-ray machine) is a subcategory of X-ray products. It has the advantages of portability, mobility, flexible operation, easy positioning, and small footprint. It is widely used in departments such as radiology, orthopedics, wards, emergency rooms, operating rooms, ICUs, as well as large-scale physical examinations, out-of-hospital emergency treatment, and is known as the "radiology department on wheels."

[0003] Mobile DR has greatly facilitated the examination of critically ill patients. For critically ill patients who cannot be moved to the DR room for examination, the mobile DR can be pushed to the bedside for examination and diagnosis, which greatly reduces the risk of critically ill patients being transferred. However, precisely because the mobile DR can take pictures in front of the bed, it lacks the radiation protection equipment such as lead walls and lead doors of conventional DR rooms, and radiation issues have become an issue that needs attention.

[0004] At present, the commonly used protection methods for mobile DR are as follows: 1. Clear the area before exposure. Before exposure, the operator notifies the surrounding people who can be evacuated to leave temporarily, generally two meters away. When used in the ward, protective measures should be taken for patients in adjacent beds, and useful harnesses should not be directed towards other patients. 2. Use protective equipment in conjunction. If there are still people around who cannot leave, it is recommended to separate them with a mobile lead screen. When operating mobile DR, staff should wear lead protective equipment, such as lead clothing, lead neckbands, lead glasses, lead hats, etc. When taking pictures, stay away as much as possible. When exposing, choose high kilovolt, low milliampere, and small photography conditions for exposure. 3. Be familiar with the operation of the equipment. Try to do a one-time exposure to avoid repeated shooting and generate greater radiation.

[0005] However, since all three protective measures have certain limitations, surrounding personnel and workers are still at risk of being exposed to X-ray radiation. Utility Model Content

[0006] In view of the problems and limitations of existing mobile DR protection measures, the utility model provides a protective device for mobile X-ray equipment, which can simply and effectively protect the X-rays of the mobile DR, protecting the staff, surrounding personnel and the patient themselves from radiation.

[0007] The utility model is implemented as follows: a protective device for a mobile X-ray device comprises an annular bracket, a lead coat and a hook; the annular bracket is fixed directly below the tube of the X-ray device through a connecting piece, the inner ring size of the annular bracket is larger than the tube size of the X-ray device, and the lead coat is suspended below the annular bracket through the hook.

[0008] Furthermore, the lead clothing comprises two wide lead clothings arranged opposite to each other and two narrow lead clothings arranged opposite to each other, and the wide lead clothings and the narrow lead clothings are bonded together by Velcro.

[0009] Furthermore, a first step and a second step are respectively provided at the junction of the wide lead coat and the narrow lead coat, the first step and the second step can be fitted with each other, and the male surface and the female surface of the Velcro are respectively fixed on the first step and the second step.

[0010] Furthermore, the annular bracket includes a mounting plate and an annular ring; the mounting plates are welded on the tops of both sides of the annular ring, the mounting plates are provided with mounting holes, and the connecting piece passes through the mounting holes and is connected to the support plate at the bottom of the tube.

[0011] Furthermore, the connecting member is a screw, the head of the screw is located at the bottom, and the screw passes upward through the mounting hole on the mounting plate and is threadedly connected to the support plate at the bottom of the tube.

[0012] Furthermore, the annular ring is rectangular.

[0013] Furthermore, a hanging hole is provided on the top of the lead suit, the bottom of the hook is inserted into the hanging hole, and the top of the hook is hooked on the annular bracket.

[0014] Furthermore, the hook includes an S-shaped hook body, a first reinforcement ring and a second reinforcement ring, the top and bottom ends of the S-shaped hook body are respectively provided with a first snap-in and a second snap-in, and the middle section of the S-shaped hook body is provided with two first connecting holes and a second connecting holes spaced apart from each other on the left and right; one end of the first reinforcement ring is passed through the first connecting hole, and the other end is buckled into the first snap-in, and one end of the second reinforcement ring is passed through the second connecting hole, and the other end is buckled into the second snap-in.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the protective device provided by the utility model includes an annular bracket, a lead coat and a hook. The annular bracket is fixed directly below the tube of the X-ray device through a connecting piece. The annular bracket has a certain bearing capacity, and the inner ring size of the annular bracket is larger than the tube size of the X-ray device, which does not affect the forward, backward, left and right rotation of the tube. The lead coat is hung below the annular bracket through a hook to form a closed annular lead coat. At this time, the annular lead coat can completely surround the exit port below the mobile DR tube. The bottom surface of the annular lead coat is above the patient's shooting site. This protective device can isolate most of the scattered rays and part of the straight rays, and only retain the straight rays above the required patient's shooting site.

[0016] It can be seen that the protective device can simply and effectively protect the X-rays of the mobile DR, protecting the staff, surrounding personnel and the patient from radiation. It solves the problems existing in the three commonly used protective measures. In addition, the protective device can be operated independently by one person, which improves the efficiency of assembly and disassembly, is not restricted by the site, is simple and flexible, has low cost and good versatility.
