Description

Technical Field

[0001] The invention relates to a diabetes full-cycle health detection system, in particular to an X-ray machine for diabetes full-cycle health detection. Background Art

[0002] Diabetes is a group of metabolic diseases characterized by high blood sugar. High blood sugar is caused by defects in insulin secretion or its biological function, or both. Long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels, and nerves. Due to the reduced resistance of diabetic patients, diabetic osteoarthritis is a common complication, which can be confirmed by X-ray examination.

[0003] In an X-ray system, the beam limiter is usually installed under the tube. The tube emits X-rays, which are projected onto the subject through the blade opening (the size of the blade opening) inside the beam limiter. The rest is absorbed and blocked by the blades and cannot be emitted. Since X-rays are harmful to the human body, it is necessary to control the projection range of X-rays so that they only irradiate the parts of the patient that need to be examined, in order to protect other parts of the patient from unnecessary X-rays that may cause harm to the human body. The beam limiter is a device used to shield excess X-rays. The device used to control the size of the beam limiter blade opening is usually called a blade drive device. Currently, beam limiter blade drives include gear swing rod drives and lead screw plus linear guide drives.

[0004] For example, patent application No. 200910141786.8 discloses a drive device that uses a gear swing rod to drive the beam limiter blades. However, the above beam limiter blade drive device has a complex structure, many parts, and high cost. In the gear swing rod drive device, the gear processing is complicated; the blade drive requires a reversing gear conversion, and the intermittent gear will affect the accuracy of the blade movement, making assembly and adjustment difficult. In the lead screw plus linear guide drive device, the cost of the lead screw and the linear guide is relatively high, and it is also difficult to achieve manual operation with a knob.

[0019] The present invention discloses a diabetes full-cycle health detection system, comprising an X-ray machine body and a beam limiter arranged on the X-ray path, the beam limiter is used to shield the excess X-rays of the X-ray machine. Figure 1 As shown, the X-ray machine beam limiter includes a base plate 1 , one end of the base plate 1 is provided with a servo motor 2 , and the servo motor 2 is connected to a gear 3 provided on the base plate 1 .

[0020] A lower bottom plate 11 is fixed to the other end of the base plate 1. A rotatable circular rotating plate 110 is arranged inside the lower bottom plate 11. The rotating plate 110 has lower blades 12. Ejectors 14 are fixed to the rotating plate 110. The ejectors 14 are evenly distributed between each lower blade 12. An upper bottom plate 21 is fixed to the ejectors 14. Specifically, the upper bottom plate 21 is fixed to the ejectors 14 by an arc groove 24 provided on the upper bottom plate 21. The beam limiter also includes a circular top plate 25. The top plate 25 is arranged above the upper bottom plate 21. The inner diameter of the ring 26 is equivalent to the diameter of the rotating plate 110.

[0021] In order to strengthen the connection between the upper and lower base plates, a fixing pin 15 is fixed to the rotating plate 110 . The fixing pin 15 is arranged on the outer end blade of the lower blade 12 . The outer end blade of the upper blade 22 is correspondingly provided with a fixing hole (not marked in the figure).

[0022] For quick and accurate assembly, a guide pin 15 for guiding the position of the upper base plate 21 is fixedly disposed on the rotary plate 11 , and a guide groove (not shown in the figure) cooperating with the guide pin 15 is correspondingly opened on the upper base plate 21 .

[0023] The upper base plate 21 is provided with an upper blade 22. Four upper blades 22 and four lower blades 12 are provided. Lead sheets are attached to the upper and lower blades to absorb X-rays. An upper torsion spring 23 is provided inside the outer end blade of each upper blade 22. Similarly, a lower torsion spring 13 is provided inside the outer end blade of each lower blade 12.

[0024] The upper and lower blades are in a scimitar shape, and the angle between each upper blade 22 and the lower blade 12 is set to 45°.

[0025] Combination Figure 2 As shown, the blade opening and closing drive of the beam limiter is through the meshing of the gear 3 with one end of the rack 4, the other end of the rack 4 is arranged below the lower bottom plate 11, and an arc-shaped small groove 41 is provided on the rack 4, a positioning pin 17 is fixed to the bottom of the rotating plate 110, and the positioning pin 17 is inserted into the arc-shaped small groove 41. When the arc-shaped small groove 41 is in motion, the rotating plate 110 is driven to rotate through the positioning pin 17. Since the angle between the upper and lower blades is 45°, the opening and closing size of the upper and lower blades can be adjusted when the rotating plate 110 rotates, and it can stop at any position at will, so as to better adapt to the shielding of excess X-rays.

[0026] The rack 4 is also provided with a straight groove 42, and a pin 18 is fixed to the bottom of the lower base plate 11, and the pin 18 is inserted into the straight groove 42. The rack 4 moves linearly within the length of the straight groove 42.

[0027] In order to make the rack 4 move better on a designated straight line, two straight grooves 42 are provided, and two pins 18 are provided accordingly, and the straight grooves 42 are coaxial with the pins 18 .

[0028] The beam limiter is also provided with a resistance meter 5 for controlling the opening and closing size of the blades, which converts the real-time position of the blades into resistance values ​​and feeds them back to the program to better control the opening and closing of the blades.

[0029] The working process of the present invention is briefly described below:

[0030] After the switch is turned on, a signal is transmitted to the servo motor 2 through a signal, which can be a forward signal or a reverse signal. The servo motor 2 drives the gear 3 connected to it to move. At the same time, the gear 3 drives the rack 4 meshing with it to move, converting the circular motion of the gear 3 into the linear motion of the rack 4. When the rack 4 moves linearly, it drives the rotating plate 110 to rotate through the arc-shaped small groove 41 and the positioning pin 17, and finally achieves a change in the position relationship between the upper and lower blades. The position of the blades shields the excess X-rays, and the angled part formed by opening is irradiated by X-rays to the patient's lesion site.

[0031] The invention has a novel structure, effectively reduces the labor intensity of the operator, improves the work efficiency, and at the same time protects the motor and reduces the cost.

[0032] The present invention has many specific implementation modes, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
