Technical Field

[0001] The present invention relates to the technical field of radiology, and in particular to a kidney imaging diagnostic device for radiological examination. Background Art

[0002] The kidney imaging diagnostic device uses x-rays to perform a cross-sectional scan of the human body. The analog signal r received by the detector is converted into a digital signal, and the attenuation coefficient of each pixel is calculated by an electronic computer. The image is then reconstructed to display the cross-sectional structure of various parts of the human body.

[0003] A Chinese patent with authorization announcement number CN113520433A discloses a kidney imaging diagnostic device for radiological examination, comprising a diagnostic bed, an imaging diagnostic mechanism and a slide, wherein the imaging diagnostic mechanism is rotatably installed on the top side of the diagnostic bed, the slide is slidably installed on the top side of the diagnostic bed, and a spray seat is installed on the bottom side of the slide; the imaging diagnostic mechanism is located below the diagnostic bed, which is convenient for the patient to lie directly on the diagnostic bed without any obstruction, and the second motor on the shaft seat drives the rotating arm to rotate, thereby driving the arc seat to rotate 180°. At this time, the imaging diagnostic mechanism is located directly above the diagnostic bed, and the third motor on the U-shaped seat drives the rotating gear to rotate, driving the U-shaped seat to move along the meshing external teeth, and at the same time, the slide connected to the connecting rod moves on the roller of the arc groove, thereby driving the scanner to move on the inner side of the arc seat, and the arc of movement is 180°. By cooperating with the rotation of the arc seat itself, 360° blind-angle scanning is achieved, and the overall device occupies a small area and is easy to operate.

[0004] However, after the existing renal imaging diagnostic device for radiological examination is used, the scanning bed is sprayed with disinfectant for disinfection, but the disinfectant is not wiped off, which causes the scanning bed to be relatively damp. At the same time, every time the patient gets off the scanning bed, it is necessary to manually press a switch to allow the disinfectant to disinfect the scanning bed, resulting in cumbersome and inconvenient operation.

[0005] Therefore, it is necessary to provide a kidney imaging diagnostic device for radiological examination to solve the above technical problems. Summary of the invention

[0006] The present invention provides a renal imaging diagnostic device for radiological examination, which solves the problem that after the existing renal imaging diagnostic device for radiological examination is used, after the scanning bed is sprayed with disinfectant for disinfection, the disinfectant is not wiped off, which causes the scanning bed to be relatively wet, and at the same time, every time the patient gets off the scanning bed, a switch needs to be pressed manually to allow the disinfectant to disinfect the scanning bed, resulting in cumbersome and inconvenient operation.

[0007] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention is a kidney imaging diagnosis device for radiological examination, comprising a base plate, a scanner fixedly connected to one side of the top of the base plate, a support seat fixedly connected to the top of the base plate, a diagnostic bed fixedly connected to the top of the support seat, a scanning couch slidably connected to the top of the diagnostic bed, limit rods fixedly connected to both ends of the inner cavity of the base plate, a sleeve block slidably sleeved on the surface of the limit rod, a C-shaped connecting plate fixedly connected to one end of the sleeve block, and the C-shaped connecting plate extends to the outside of the diagnostic bed, arc plates are arranged at one end of two groups of C-shaped connecting plates close to each other, a disinfection mechanism is arranged at one end of the surface of one group of C-shaped connecting plates, a disinfection and cleaning mechanism is arranged on one side of the arc plate, and a power drive mechanism is arranged in the inner cavity of the diagnostic bed.

[0011] By adopting the above technical solution, when the water pump is started, the disinfectant in the liquid storage tank is sprayed onto the surface of the scanning bed to disinfect it, thereby preventing the spread of bacteria between patients.

[0012] In the above-mentioned renal imaging diagnostic device for radiological examination, the disinfection and cleaning mechanism includes: three groups of mounting plates arranged on one side of the arc-shaped plate, a positioning rod is arranged on the top of the mounting plate, and the positioning rod passes through the mounting plate, the bottom of the positioning rod is fixedly connected with the arc-shaped mounting plate, and the arc-shaped mounting plate is located above the scanning bed, a sponge block is arranged at the bottom of the arc-shaped mounting plate, and a spring is sleeved below the mounting plate on the surface of the positioning rod.

By starting the water pump 6, the disinfectant in the liquid storage tank 20 is transported to the atomizing nozzle 11 through the liquid guide tube 7, and then sprayed to the surface of the scanning bed 4 through the atomizing nozzle 11 to disinfect it.

[0040] See also Figure 3 and Figure 5 The disinfection and cleaning mechanism includes: three groups of mounting plates 10 arranged on one side of the arc plate 9, a positioning rod 12 is arranged on the top of the mounting plate 10, and the positioning rod 12 passes through the mounting plate 10, and the bottom of the positioning rod 12 is fixedly connected with an arc mounting plate 15, and the arc mounting plate 15 is located above the scanning bed 4, and a sponge block 16 is arranged at the bottom of the arc mounting plate 15, and a spring 13 is sleeved below the mounting plate 10 on the surface of the positioning rod 12. When the arc plate 9 moves, it will drive the sponge block 16 on the arc mounting plate 15 to move together and clean the disinfectant sprayed by the atomizing nozzle 11 on the surface of the scanning bed 4, and at the same time, the elastic force of the spring 13 can drive the arc mounting plate 15 to move down and closely adhere to the surface of the scanning bed 4, so that the sponge block 16 fits more closely on the surface of the scanning bed 4, improving the wiping effect.

[0041] See also Figure 3-4 The power drive mechanism includes: a motor 24 disposed at one side of the bottom of the inner cavity of the diagnosis bed 3, the output end of the motor 24 is rotatably connected to a threaded rod 22, and one end of the threaded rod 22 is rotatably connected to one side of the inner cavity of the diagnosis bed 3, the surface of the threaded rod 22 is threadedly connected to an internal threaded sleeve block 23, and both ends of the internal threaded sleeve block 23 are fixedly connected to a connecting plate 21, and one end of the connecting plate 21 away from the internal threaded sleeve block 23 is connected to one end of the sleeve block 18. The threaded rod 22 is driven to rotate by the motor 24, so that the internal threaded sleeve block 23 slides on the threaded rod 22, and then the C-shaped connecting plates 19 on the two sets of sleeve blocks 18 are driven to move by the connecting plate 21, thereby causing the arc plate 9 to move along the top of the scanning bed 4.

[0042] See also Figure 3 and Figure 5 A liquid injection port is provided on one side of the top of the liquid storage tank 20, and a sealing plug is provided on the inner side of the liquid injection port. By the provision of the liquid injection port, it is convenient to replenish disinfectant in the liquid storage tank 20.

[0043] See also Figure 2-5The two ends of the top of the diagnostic bed 3 are provided with a slide groove 8, the inner side of the slide groove 8 is slidably connected with a slider 14, and the top of the slider 14 is connected to the surface of the C-shaped connecting plate 19. The slider 14 can assist in supporting the C-shaped connecting plate 19 and assist in moving the C-shaped connecting plate 19.

[0044] See also Figure 2 and Figure 5 The top of the scanning bed 4 is formed by an arc, and the arc-shaped mounting plate 15 and the top of the scanning bed 4 are adapted to each other. It is convenient to make the sponge block 16 on the arc-shaped mounting plate 15 fit the surface of the scanning bed 4, thereby improving the wiping effect of the sponge block 16.

[0045] See also Figure 1 The scanning bed 4 is provided with three groups of pressure sensors, and the three groups of pressure sensors are respectively a front sensor, a middle sensor and a rear sensor. The front sensor corresponds to the patient's head, the middle sensor corresponds to the patient's buttocks, and the rear sensor corresponds to the patient's legs. When the patient stands up from the scanning bed 4, but the buttocks do not leave the scanning bed 4, the control module still cannot start the disinfection process. Only when the patient leaves the scanning bed 4, the motor 24 and the water pump 6 can be started for disinfection, so that the device can automatically disinfect and improve the safety of operation.

[0046] See also Figure 1 The inner cavity of the diagnostic bed 3 is provided with a control module, a transmission module and an analysis module. By providing three sets of pressure sensors inside the scanning bed 4, when the patient leaves the scanning bed 4, the motor 24 and the water pump 6 can be started by the control module to automatically disinfect the surface of the scanning bed 4, without the need for medical staff to manually operate buttons, thus saving time and effort.

[0047] The working principle of the renal imaging diagnosis device for radiological examination provided by the present invention when in use is that three groups of pressure sensors are arranged inside the scanning bed 4. When the patient lies on the scanning bed 4, the patient's head will press the front sensor, the buttocks will press the middle sensor, and the legs will press the rear sensor. Then the scanning bed 4 is started to push the patient into the inside of the scanner 2 for scanning examination. When the examination is completed, the scanning bed 4 is reset. Then, when the patient leaves the scanning bed 4, the three groups of pressure sensors cannot sense the existence of gravity on the surface of the scanning bed 4. The gravity data will be transmitted to the analysis module through the transmission module. After the analysis module analyzes the data and determines that the patient has left the scanning bed 4, the motor 24 and the water pump 6 are started through the control module, and the threaded rod 22 is driven to rotate by the motor 24, so that the internal threaded sleeve block 23 slides on the threaded rod 22, and then the connecting plate 21 drives the C-shaped connecting plates 19 on the two sets of blocks 18 to move, thereby making the arc plate 9 move along the top of the scanning bed 4. At the same time, the water pump 6 transports the disinfectant in the liquid storage tank 20 to the atomizing nozzle 11 through the liquid guide tube 7, and then sprays it onto the surface of the scanning bed 4 through the atomizing nozzle 11 for disinfection. At the same time, when the arc plate 9 moves, it will drive the sponge block 16 on the arc mounting plate 15 to move together and clean the disinfectant sprayed onto the surface of the scanning bed 4 by the atomizing nozzle 11. At the same time, the elastic force of the spring 13 can drive the arc mounting plate 15 to move down and fit tightly to the surface of the scanning bed 4, so that the sponge block 16 fits more closely to the surface of the scanning bed 4, thereby improving the wiping effect. When the arc plate 9 reaches the farthest end of the scanning bed 4, the arc plate 9 is reset by reversing the motor 24, and then the operation of the motor 24 is stopped, so that the next patient lies on the scanning bed 4 for scanning examination.
