Description

Technical Field

[0001] The invention relates to the technical field of CT scanning protection, in particular to a controllable CT scanning radiation protection bed. Background Art

[0002] CT, or computer tomography, is a medical imaging technology that uses precise X-ray beams and highly sensitive detectors to scan the human body layer by layer, and uses a computer to process the scanned data to generate high-resolution images of the body's internal cross-section, coronal or sagittal planes. CT images reflect the degree of X-ray absorption by organs and tissues in different grayscales, have high-density resolution, and can clearly display soft tissue and bone structures. CT scanning is widely used in the diagnosis of various diseases due to its fast and clear imaging capabilities.

[0003] During CT scans, a large number of X-rays enter the surrounding environment through scattering and transmission, causing the parts of the examiner that do not need to be scanned to be irradiated by X-rays. Compared with adults, children have more sensitive tissues and should be protected more, so more and more protection research has been conducted in recent years. For example, when performing CT scans on children, people use lead shielding and covering methods, using lead sheets or protective neckbands to protect the non-examined parts of the children from above;

[0004] Firstly, it is essentially just a simple covering protection. The X-rays emitted by the CT machine have the characteristic of 360-degree dispersion, which means that in addition to the upper area, the lower and surrounding areas of the patient will also be exposed to the radiation range of the X-rays, and the protection effect is poor; secondly, during the long CT scan process, children are in such an unfamiliar environment, which makes it easier for patients to feel nervous, anxious, uncomfortable, and under great mental stress.

[0005] To this end, we have developed a new controllable CT scanning radiation protection bed. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Examples, such as Figure 1 - Figure 6 As shown, an embodiment of the present invention provides a controllable CT scanning radiation protection bed, comprising a bed body 3, a bed board 4 is fixedly connected to the upper surface of the bed body 3, a fixed lead plate 8 is fixedly connected to the two ends of the upper surface of the bed board 4 and a movable lead plate 11 is slidably connected, a fixed block 5 is fixedly connected to the front and rear sides of one end of the outer surface of the bed body 3, a first protective cover 6 is fixedly connected to the upper surfaces of the two fixed blocks 5, a curved side plate 7 is fixedly connected to one end of the first protective cover 6, and a display mechanism is slidably connected to the bottom of the first protective cover 6;

[0031] like Figure 1 As shown, the front and rear sides of the other end of the outer surface of the bed body 3 are slidably connected with movable blocks 9, the opposite sides of the two movable blocks 9 are fixedly connected with movable lead plates 11, the upper surfaces of the two movable blocks 9 are commonly fixedly connected with a second protective cover 12, and the lower surfaces of the two movable blocks 9 are symmetrically fixedly connected with connecting plates 10, and one side of the outer surfaces of the plurality of connecting plates 10 is installed with a limiting mechanism that matches the bed body 3;

[0032] Among them, the first protective cover 6 and the second protective cover 12 are both in an arc-shaped semicircular structure, and the first protective cover 6 and the second protective cover 12 are both made of lead glass, which together with the fixed lead plate 8 and the movable lead plate 11 can better protect the child's body from radiation.

[0033] like Figure 2 and Figure 6As shown, the display mechanism includes a moving block 21 slidably connected to the bottom side wall of the first protective cover 6, a connecting rod 22 is fixedly connected to the lower surface of the moving block 21, one end of the connecting rod 22 is fixedly connected to a rotating platform 23, one end of the upper surface of the rotating platform 23 is rotatably connected to a support rod 24, one end of the support rod 24 is hinged to a connecting end 25 (the hinged manner can be achieved by a damping shaft commonly used on a notebook computer screen in the prior art, so that the direction of the display screen 26 can be changed by rotating the connecting end 25, and the direction is fixed and will not be easily deflected by external force), and one end of the connecting end 25 is fixedly connected to the display screen 26;

[0034] The display screen 26 can play music or cartoons. When the child lies in the relatively closed and unfamiliar space of the protective bed, cartoons and music can express emotions through their unique artistic forms. Cartoons, as a form of visual art, can attract children's attention through rich pictures and storylines, and cheerful nursery rhymes, with their brisk rhythm and childlike lyrics, can effectively eliminate children's nervousness, allowing them to temporarily forget the troubles of reality, and effectively help children relieve tension and anxiety.

[0035] Furthermore, by pulling the display screen 26, the moving block 21 is driven to move along the bottom of the first protective cover 6. At the same time, the position of the bed board 4 facing the display screen 26 can be changed by rotating the support rod 24, and the angle of the display screen 26 relative to the bed board 4 can be changed by rotating the connecting end 25 to adapt to the different viewing angles of the children facing the display screen in different situations, which is more flexible to use.

[0036] Among them, Figure 5 As shown, the lower surface of the first protective cover 6 is symmetrically fixedly connected with a support plate 27, the lower surface of the moving block 21 is slidably connected to the inner sides of the two support plates 27, and the outer surface of the connecting rod 22 is slidably connected to the opposite sides of the two support plates 27. The existence of the support plates 27 provides a certain support for the moving block 21, preventing it from being separated from the sliding connection with the bottom side wall of the first protective cover 6 due to the action of gravity, and there is also a certain width between the two support plates 27, which can facilitate the passage of the connecting rod 22 without interfering with the changing position of the connecting rod 22 and the moving block 21 along the bottom of the first protective cover 6.

[0037] like Figure 3As shown, the limiting mechanism includes a fixed sleeve 18 and a slider 13 respectively penetrating and fixedly connected to the side wall of the connecting plate 10, the side wall of the fixed sleeve 18 penetrates and is slidably connected with an insertion rod 15, one end of the insertion rod 15 is sleeved and fixedly connected with a movable sleeve 14, and one side of the outer surface of the movable sleeve 14 abuts against the fixed sleeve 18, the other end of the insertion rod 15 is fixedly connected with a limiting block 16, and a spring 17 is fixedly connected between the limiting block 16 and the side wall of the fixed sleeve 18, and the spring 17 is sleeved on the outer surface of the insertion rod 15;

[0038] In the initial state, under the action of the elastic force of the spring 17 itself, the limit block 16 is in a position extending to the inner side of the slider 13. At this time, the limit block 16 can lock the slider 13 and the position of the connecting plate 10. Correspondingly, when the movable sleeve 14 is pinched and pulled outward, the movable sleeve 14 will drive the insertion rod 15 to move outward, thereby receiving the limit block 16 inside the fixed sleeve 18 and compressing the spring 17. At this time, the position of the slider 13 and the connecting plate 10 can be changed, and when it is subsequently determined that the slider 13 has moved to the appropriate position, the movable sleeve 14 can be released. Under the elastic force of the spring 17 to restore the initial state, the limit block 16 can extend out of the slider 13 again and lock the position of the connecting plate 10.

[0039] like Figure 1 and Figure 4 As shown, the front and rear sides of the outer surface of the bed body 3 are printed with scale lines 20, and the front and rear sides of the outer surface of the bed body 3 and the positions corresponding to the two scale lines 20 are respectively provided with slide grooves 19 matching the slider 13, and the sliding between the slider 13 and the slide groove 19 indirectly constitutes a sliding connection between the connecting plate 10 and even the movable block 9 and the bed body 3, so as to realize the change of the position of the movable lead plate 11 relative to the bed board 4;

[0040] At the same time, the side walls of the two slide grooves 19 are provided with a plurality of positioning holes matching the scale lines 20, and the diameters of the plurality of positioning holes are matched with the limit blocks 16. The limit blocks 16 are inserted into any of the positioning holes, that is, by aligning the limit blocks 16 with the scale lines and inserting them into the positioning holes, the positioning of the movable lead plate 11 and the second protective cover 12 can be achieved more accurately.

[0041] Correspondingly, the fixing sleeve 18 is provided with a through hole matching the insertion rod 15, and the side walls of the fixing sleeve 18 and the sliding block 13 are both provided with a clearance groove matching the limit block 16, wherein the clearance groove inside the side wall of the limit block 16 can just accommodate the limit block 16 passing through, and the clearance groove opened inside the side wall of the fixing sleeve 18 and the through hole form a stepped hole structure, which can enable the limit block 16 to be received inside the fixing sleeve 18, so that the limit block 16 can be moved out of the positioning hole and then pass through the sliding block 13, and finally be received into the side wall of the fixing sleeve 18, thereby not interfering with the sliding of the sliding block 13 along the sliding groove 19.

[0042] like Figure 1 As shown, support frames 1 are symmetrically fixedly connected to both ends of the lower surface of the bed 3, and universal wheels 2 are symmetrically fixedly connected to the lower surfaces of the two support frames 1. The support frames 1 support the bed 3 to a certain height, and the existence of the universal wheels 2 at the bottom of the support frames 1 enables the entire protective window to be easily moved to a position, which is convenient for CT examination. In actual applications, a linear moving mechanism can be arranged between the support frame 1 and the bed 3, and the support frame 1 is fixed to the linear moving mechanism, and the output end of the mechanism is fixed to the bed 3 during linear movement, and is utilized to drive the bed 3 to move, thereby facilitating CT scanning.

[0043] Working principle: First, when a child patient (the device of the present application is specifically for child patients under 8 years old and under 1.5 meters tall) needs to be examined, the first step is to instruct the patient to remove all metal foreign objects or metal ornaments on his body before the examination, and lie flat on the scanning bed during the examination, and a professional doctor will help the patient to position the body. If a head examination is required, the body part of the child patient will be covered with a movable lead plate 11 and a second protective cover 12. When an abdominal examination is required, only the abdomen is exposed, and the head and chest are covered under the first protective cover 6 (in actual application, the width of the first protective cover 6 is about 50 cm, so as to be able to cover the child patient's head to half of the chest or The position of the male nipple is preferably, so that the upper body of the child patient can be better protected when the liver, kidney and other parts are examined, achieving better protection performance; accordingly, since the scanning aperture of the common CT scanner scanning frame is 60cm, the radius of the semicircular structure of the first protective cover 6 and the second protective cover 12 should be set at about 25cm, and the width of the bed board 4 is set at about 50cm, so that the whole can pass through the central channel of the CT scanner normally), and the lower body is shielded under the second protective cover 12, and the examination of other parts is like this, which realizes the simultaneous satisfaction of the radiation protection requirements of the upper and lower areas of the child patient, and reduces the risk of unnecessary radiation to the non-examination parts of the patient;

[0044] During this period, the staff can pinch the movable sleeve 14 and pull it outward, and the movable sleeve 14 will drive the insertion rod 15 to move outward, so that the limit block 16 is received in the fixed sleeve 18 and the spring 17 is compressed. At this time, the positions of the slider 13 and the connecting plate 10 can be changed, and when it is determined that the slider 13 has moved to a suitable position, the movable sleeve 14 can be released. Under the elastic force of the spring 17 to restore the initial state, the limit block 16 can extend the slider 13 again and lock the position of the connecting plate 10, thereby moving the movable lead plate 11 and the second protective cover 12 relative to the bed board 4 and locking them (in actual application, the second protective cover 12 and the movable lead plate 11 can be automated by external electrical equipment such as electric push rods, linear motors, etc., so that the movement and locking of the second protective cover 12 can be more easily controlled);

[0045] In order to reduce the weight of the whole device, except for the first protective cover 6, the second protective cover 12, the curved side plate 7, the fixed lead plate 8 and the movable lead plate 11 which are made of lead material, the rest such as the bed plate 4, the bed body 3, the fixed block 5, the support frame 1, etc. can be made of carbon fiber material, so that the strength is guaranteed while the weight is greatly reduced, which is convenient for the movement of the equipment;

[0046] Subsequently, after the child patient is placed, the display screen 26 can be pulled to drive the moving block 21 to move along the bottom of the first protective cover 6. At the same time, the position of the bed board 4 facing the display screen 26 can be changed by rotating the support rod 24, and the angle of the display screen 26 relative to the bed board 4 can be changed by rotating the connecting end 25, so that the display screen 26 can be seen more easily by the child patient, and music or cartoons can be played on the display screen to attract the child's attention and reduce his or her nervous mental stress. The overall CT scanning radiation protection bed is more functional.

[0047] 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.
