Description

Technical Field

[0001] This invention relates to the field of spectral detection, and more particularly to a spectral analysis device and a method for preparing medical cesium carbonate. Background Technology

[0002] Cesium carbonate for medical use is an important medical raw material, widely used in the preparation of radiopharmaceuticals, synthesis of diagnostic reagents, and pharmaceutical excipients. Its purity and impurity content are directly related to the safety, efficacy, and stability of pharmaceutical products. Therefore, accurate detection and analysis of cesium carbonate for medical use is of utmost importance.

[0003] Among them, infrared spectroscopy detection technology has become a common means of qualitative identification, purity analysis and impurity screening of chemical substances due to its advantages such as simple operation, speed and efficiency, non-destructive testing and small sample volume. Its core principle is based on the characteristic absorption of electromagnetic waves in the infrared region by different chemical groups. By measuring the infrared absorption spectrum of the sample, the functional group structure, purity and impurity information of the substance can be obtained, so as to realize the qualitative and quantitative analysis of the substance.

[0004] In existing technologies, if the infrared generator is left exposed for a long time during the detection and analysis process, the infrared emitter is easily affected by external factors. External dust can easily cover the emitting lens end of the infrared generator, which can cause errors in spectral detection and analysis, thereby affecting the detection accuracy.

[0005] Therefore, it is necessary to provide a spectroscopic analysis device and a method for preparing medical cesium carbonate to solve the above-mentioned technical problems. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides a spectral analysis device, including an analyzer, an analysis mechanism, and a support mechanism;

[0008] The top of the analyzer is rotatably connected to a cover plate, and an installation plate is fixed inside the analyzer. A side plate is fixed on the outer wall of the installation plate and located inside the analyzer.

[0009] The analysis mechanism includes a mounting sleeve fixed inside the side plate, a sealing plate installed on the top of the mounting sleeve, a spring rod slidably connected inside the mounting sleeve, a lifting frame fixed inside the mounting sleeve and at the bottom end of the spring rod, an infrared generator installed inside the lifting frame, two flip plates rotatably mounted at the bottom end of the mounting sleeve via a torsion spring, and a guide wheel fixed inside the mounting sleeve and above the two flip plates.

[0010] The supporting mechanism includes a flipping frame, inside which is installed an electric turntable, and the electric turntable has multiple holes for storing samples.

[0011] Preferably, the spring rod moves vertically about the center of the sealing plate, and the top of the spring rod is higher than the top of the analyzer.

[0012] Preferably, the bottom of the lifting frame has a conical structure, and the outer wall of the guide wheel and the outer wall of the lifting frame are in close contact with each other.

[0013] Preferably, a support plate is fixedly installed at the bottom of the analyzer, and a slotted plate is fixedly installed on the top of the support plate and below the flipping frame. The slotted plate has a horizontal slot and an oblique slot respectively. An electric cylinder is installed on the back of the mounting plate, and a moving frame is installed at the output end of the electric cylinder. A connecting plate is rotatably connected to the side wall of the moving frame, and a positioning wheel is rotatably connected to the outer wall of the connecting plate.

[0014] Preferably, the positioning wheel is located inside the transverse groove, and the outer wall of the positioning wheel and the inner wall of the transverse groove are in contact with each other.

[0015] Preferably, the tilting frame and the moving frame are rotatably connected, the hinge joints of the tilting frame and the moving frame are keyway connected to the hinge joints of the connecting plate and the moving frame, and the electric cylinder passes through the outside of the analyzer.

[0016] Preferably, cleaning services are also included;

[0017] The top of the flipping frame is fixedly provided with a top plate. The cleaning mechanism includes a bracket installed inside the analyzer and located on one side of the analyzer. Two spring telescopic rods are fixedly provided at the bottom of the bracket. Positioning plates are fixedly provided at the bottom ends of the two spring telescopic rods. Cleaning rollers are rotatably connected to the opposite side of the two positioning plates. Baffles are installed on the side walls of the two positioning plates. Auxiliary wheels are rotatably installed at the bottom of the two positioning plates through torsion springs.

[0018] Preferably, the outer wall of the cleaning roller is in contact with the upper surface of the electric turntable, the two auxiliary wheels are located directly above the top plate, and the outer walls of the two auxiliary wheels are in contact with the outer walls of the two baffles.

[0019] The method for preparing medical-grade cesium carbonate includes the following steps:

[0020] S1: Prepare an extraction tank, a pure water tank, and a carbonate tank to prepare a carbonate solution;

[0021] S2: Add caustic soda flakes to the rubidium and cesium feed tank and then to the separation and extraction tank. At the same time, add the extractant, wash water, and back-extraction acid to the extraction tank through the extractant high-level tank, pure water high-level tank, and carbonate high-level tank, respectively, for extraction.

[0022] After the loaded organic material passes through a washing section, it undergoes carbon dioxide back-extraction. The back-extraction solution is a cesium bicarbonate solution, which is then further carbonized to obtain a cesium bicarbonate solution. Centrifugation separates this solution into a wet cesium bicarbonate feed. The cesium bicarbonate is then dried and decomposed to obtain the product cesium carbonate.

[0023] S3: Dissolve the cesium carbonate product in high-purity sulfuric acid to generate a cesium sulfate solution. Then, extract, concentrate under reduced pressure, and cool to crystallize to obtain medical-grade cesium carbonate.

[0024] S4: Prepare a test sample from medical cesium carbonate for testing and analysis. The test and analysis must be performed in a spectral analysis device. The sample needs to be placed in a carrier mechanism and detected and analyzed by infrared spectroscopy emitted by the analysis mechanism.

[0025] Compared with related technologies, the spectral analysis device and the method for preparing medical cesium carbonate provided by the present invention have the following beneficial effects:

[0026] Compared to traditional designs, when not in use, the infrared generator is completely concealed within the mounting sleeve. Two closed flaps protect the infrared generator. During testing, the user can automatically extend the infrared generator by flipping the closed cover. As the generator extends, the two flaps flip synchronously to automatically avoid it. Therefore, in addition to protection, external factors are prevented from covering the infrared generator's emitting end, effectively improving spectral detection accuracy. At the same time, it can also effectively protect the infrared generator to further enhance the accuracy of spectral detection. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] This invention provides a spectroscopic analysis device and a method for preparing medical cesium carbonate.

[0049] First embodiment:

[0050] Please see Figures 1 to 6 A spectral analysis device includes an analyzer 1, an analysis mechanism 5, and a connecting plate 69;

[0051] The top of the analyzer 1 is rotatably connected to a cover plate 2, and an installation plate 3 is fixed inside the analyzer 1. A side plate 4 is fixed on the outer wall of the installation plate 3 and located inside the analyzer 1.

[0052] The analysis mechanism 5 includes a mounting sleeve 51 fixed inside the side plate 4. A sealing plate 52 is installed on the top of the mounting sleeve 51. A spring rod 53 is slidably connected inside the mounting sleeve 51. A lifting frame 54 is fixed inside the mounting sleeve 51 and at the bottom end of the spring rod 53. An infrared generator 55 is installed inside the lifting frame 54. Two flip plates 56 are rotatably installed at the bottom end of the mounting sleeve 51 via a torsion spring. A guide wheel 57 is fixed inside the mounting sleeve 51 and above the two flip plates 56.

[0053] The connecting plate 69 includes a flipping frame 67, and an electric turntable 68 is installed inside the flipping frame 67. The electric turntable 68 has multiple holes for storing samples inside.

[0054] The spring rod 53 moves vertically about the center of the sealing plate 52, and the top of the spring rod 53 is higher than the top of the analyzer 1.

[0055] The bottom of the lifting frame 54 has a conical structure, and the outer wall of the guide wheel 57 and the outer wall of the lifting frame 54 are in close contact with each other.

[0056] Please see Figure 6 Before testing, users need to place the medical cesium carbonate tablets sequentially into the various bearing holes within the electric turntable 68.

[0057] Please see Figures 1 to 3 During the testing process, the user needs to flip the closed cover 2 and then start the analyzer 1 to perform spectral detection on the medical cesium carbonate tablet sample.

[0058] Please see Figure 4When the analysis mechanism 5 is in its initial state, and the cover plate 2 is not closed with the analyzer 1, the top of the spring rod 53 is at its highest point, and the two flaps 56 are closed to the bottom of the mounting sleeve 51. The infrared generator 55 is inside the mounting sleeve 51. Therefore, when not being detected, the infrared generator 55 cannot be disturbed by external factors.

[0059] Please see Figure 5 When the cover plate 2 is closing, the cover plate 2 will be subjected to downward force from the spring rod 53. The spring rod 53 drives the lifting frame 54 and the infrared generator 55 to descend. During the descent of the lifting frame 54, the guide wheel 57 under the inclined surface at the bottom controls the flip plate 56 to flip about the bottom hinge of the mounting sleeve 51. During the flipping process, the two flip plates 56 open to form an opening. At this time, the infrared generator 55 is fully exposed. After exposure, the infrared generator 55 emits penetrating infrared light into the medical cesium carbonate tablet sample.

[0060] Sample molecules selectively absorb infrared photons that match their inherent vibrational frequencies (where carbonate ions exhibit a fixed characteristic absorption peak), while unabsorbed infrared light is transmitted or diffusely reflected. The infrared light carrying sample molecule information is focused by the optical path system to the spectrometer and separated into monochromatic infrared light.

[0061] Monochromatic infrared light is incident on an infrared detector, which converts the light intensity signal into an electrical signal and transmits it to a data processing unit. The data processing unit amplifies, filters, performs analog-to-digital conversion and Fourier transform on the electrical signal, calculates the absorbance at different wavenumbers, generates a complete infrared absorption spectrum of the sample to be tested, and stores it synchronously in the device database.

[0062] In one application scenario, the aforementioned spectroscopic analysis device can be used for spectroscopic analysis of common cesium carbonate;

[0063] When performing spectral analysis on ordinary cesium carbonate, the ordinary cesium carbonate is made into a sample tablet and placed in the well of the electric turntable 68 within the connecting plate 69. The specific detection and analysis principle is as described above.

[0064] In another application, the aforementioned spectroscopic analysis device can be used to perform spectroscopic analysis on a variety of other medical chemicals.

[0065] This embodiment:

[0066] Medical-grade cesium carbonate has characteristic infrared absorption peaks that can directly reflect its molecular structure and functional group information. By analyzing the position, shape, and relative intensity of the characteristic peaks, it is possible to quickly determine whether a sample is cesium carbonate, effectively distinguishing between medical-grade and industrial-grade cesium carbonate, avoiding confusion and misuse of raw materials. Infrared spectroscopy can directly detect powdered medical-grade cesium carbonate, requiring only simple tablet compression or diffuse reflectance testing to complete the analysis. There is no need for cumbersome operations such as digestion, extraction, and derivatization, which greatly shortens the detection cycle and is suitable for rapid quality inspection and batch screening in the pharmaceutical production process.

[0067] Secondly, compared to traditional designs, when not in use, the infrared generator 55 is completely hidden inside the mounting sleeve 51. The two closed flaps 56 can protect the infrared generator 55. During the detection process, the user can automatically extend the infrared generator 55 by flipping the closed cover 2. During the extension process, the two flaps 56 flip synchronously to automatically avoid the infrared generator. Therefore, in addition to protection, external factors can be prevented from covering the emitting end of the infrared generator 55, which can effectively improve the spectral detection accuracy. At the same time, it can also protect the infrared generator 55 well and further improve the accuracy of spectral detection.

[0068] Second embodiment:

[0069] Please see Figure 6 and Figure 9 The analyzer 1 has a support plate 61 fixed at the bottom. The support plate 61 has a groove plate 62 fixed at the top and below the flipping frame 67. The groove plate 62 has a horizontal groove 63 and an oblique groove 64 respectively. The mounting plate 3 has an electric cylinder 65 installed on the back. The output end of the electric cylinder 65 has a moving frame 66 installed. The side wall of the moving frame 66 is rotatably connected to a connecting plate 69. The outer wall of the connecting plate 69 is rotatably connected to a positioning wheel 610.

[0070] The positioning wheel 610 is located inside the transverse groove 63, and the outer wall of the positioning wheel 610 and the inner wall of the transverse groove 63 are in contact with each other.

[0071] The flip frame 67 and the moving frame 66 are rotatably connected. The hinge joints of the flip frame 67 and the moving frame 66 are keyway connected to the hinge joints of the connecting plate 69 and the moving frame 66. The electric cylinder 65 passes through the outside of the analyzer 1.

[0072] Please see Figure 6 and Figure 7 The user starts the electric cylinder 65 to push the moving frame 66, which controls the flipping frame 67 and the electric turntable 68 to push from the initial left side to the right side. During the pushing process, the positioning wheel 610 moves horizontally in the transverse groove 63 inside the slot plate 62.

[0073] Please see Figure 7 and Figure 8Furthermore, as the tilting frame 67 moves, the top plate 611 also moves with the tilting frame 67 to the position of the auxiliary wheel 76. The right slope of the top plate 611 will abut against the force-bearing auxiliary wheel 76 and roll adaptively to the top surface of the top plate 611. During the rising process, the positioning plate 73 drives the spring telescopic rod 72 to rise. During the rising process, the cleaning roller 74 is simultaneously driven to rise away from the upper surface of the electric turntable 68. In the process before unloading, the cleaning roller 74 automatically separates from the electric turntable 68. The purpose of this is to protect the sample on the one hand and to ensure that the cleaning roller 74 is cleaner on the other hand.

[0074] Understandably: Since the baffle 75 blocks the right side of the auxiliary wheel 76, it can ensure that the auxiliary wheel 76 cannot flip to the right, thus smoothly controlling the rise of the cleaning roller 74;

[0075] Please see Figure 9 When the moving frame 66 moves to the top of the inclined groove 64, the connecting plate 69 follows and drives the positioning wheel 610 to adaptively move from the horizontal groove 63 to the inside of the inclined groove 64. During the movement of the positioning wheel 610, it will drive the connecting plate 69 to rotate clockwise. During the clockwise rotation of the connecting plate 69, it will drive the flipping frame 67 to flip clockwise inside the moving frame 66, thereby causing the electric turntable 68 to flip clockwise synchronously to assist in sample pressing and feeding.

[0076] This embodiment:

[0077] The automatic flipping action assists in the unloading of samples after testing. Combined with the testing requirements of medical cesium carbonate and the requirements of infrared spectroscopy for clean optical path, repeatability, and batch efficiency, it can eliminate human contact contamination and ensure the cleanliness of samples and the testing environment. In existing technologies, manual unloading is often used. Sweat from the operator's hands, clothing fibers, environmental dust, etc., can easily adhere to the sample surface or fall into the connecting plate 69. This not only contaminates the samples that need to be recovered after testing, but may also introduce external impurities, affecting the accuracy of subsequent tests on other samples, and failing to meet the cleanliness requirements of medical-grade testing.

[0078] The automatic flip-assisted unloading can realize the full automation of sample unloading after testing, eliminating the need for direct manual contact with the sample and the supporting mechanism. This fundamentally avoids the pollution risk caused by manual operation, while also avoiding the safety hazards that may arise from operators coming into contact with medical cesium carbonate powder. It ensures that the cleanliness of the sample is not compromised, the testing environment meets clean testing standards, and improves the standardization of the entire testing process.

[0079] Secondly, the material feeding is more thorough, significantly reducing sample residue and improving the repeatability and accuracy of the test. Medical cesium carbonate is a fine powder with a certain degree of hygroscopicity, which easily adheres to the inner wall and corners of the connecting plate 696 during the test. Existing manual feeding methods are difficult to completely clean the residual powder. The additional feeding mechanism with scraper and air blowing is not only complex in structure, but may also cause powder to fly or remain due to scraper wear or improper air blowing force. In this case, the flipping frame 67 can automatically flip and tilt when it is moved outside the analyzer 1, which makes it convenient for staff to thoroughly clean the holes in the electric turntable 68 and further improve the accuracy of the test.

[0080] Third embodiment:

[0081] Please see Figures 10 to 11 It also includes 7 cleaning agencies;

[0082] The top of the flipping frame 67 is fixedly provided with a top plate 611. The cleaning mechanism 7 includes a bracket 71 installed inside the analyzer 1 and located on one side of the analyzer 5. Two spring telescopic rods 72 are fixedly provided at the bottom of the bracket 71. Positioning plates 73 are fixedly provided at the bottom ends of the two spring telescopic rods 72. Cleaning rollers 74 are rotatably connected to the opposite side of the two positioning plates 73. Baffles 75 are installed on the side walls of the two positioning plates 73. Auxiliary wheels 76 are rotatably installed at the bottom of the two positioning plates 73 through torsion springs.

[0083] The outer wall of the cleaning roller 74 is in contact with the upper surface of the electric turntable 68, the two auxiliary wheels 76 are located directly above the top plate 611, and the outer walls of the two auxiliary wheels 76 are in contact with the outer walls of the two baffles 75.

[0084] Please see Figure 10 and Figure 11 In the second embodiment, after all the sample tablets in the electric turntable 68 have been fed out, the user starts the electric cylinder 65 to drive the moving frame 66 to control the flipping frame 67 to reset from the right side to the initial left side position.

[0085] During the reset process, the top plate 611 will move synchronously with the tilting frame 67. When the left side of the top plate 611 is displaced, it will contact the force-bearing auxiliary wheel 76 and tilt to the left. During the tilting process, the auxiliary wheel 76 will not affect the lifting and lowering of the positioning plate 73 and the spring telescopic rod 72. Therefore, when the tilting frame 67 is displaced and reset, the cleaning roller 74 can form a close contact with the electric turntable 68, and the cleaning roller 74 will roll to clean the surface of the electric turntable 68.

[0086] Understandably: Since there is no obstruction on the left side of the auxiliary wheel 76, when the top plate 611 is subjected to force from the left side of the auxiliary wheel 76, the auxiliary wheel 76 can be flipped smoothly.

[0087] This embodiment:

[0088] Medical-grade cesium carbonate is highly hygroscopic, has fine particles, and is easy to adhere to. Simply flipping the plate to unload it is not enough to completely remove the trace amounts of powder remaining on the surface of the connecting plate 69. Residual samples can cause problems such as impurities, baseline drift, and overlapping characteristic peaks in subsequent tests. By automatically activating the cleaning roller 74 during the reset process, the surface of the connecting plate 69 can be continuously and uniformly cleaned, effectively removing adhesive residual powder and dust, keeping the surface of the connecting plate 69 clean, avoiding interference from previous samples to subsequent tests, significantly improving the repeatability and accuracy of infrared spectroscopy detection, and meeting the high-precision requirements for the detection of trace impurities in medical-grade cesium carbonate.

[0089] This structure synchronously couples the reset action with the cleaning action, eliminating the need for a separate cleaning station and additional waiting time. The rolling cleaning is completed synchronously on the path of the connecting plate 69 as it returns from the unloading position to the initial detection position, avoiding the time loss caused by step-by-step actions, shortening the detection cycle of a single sample, and significantly improving the overall detection efficiency.

[0090] A method for preparing medical-grade cesium carbonate, characterized by comprising the following steps:

[0091] S1: The extractant is delivered to the extractant high-level tank by the extractant delivery pump, and pure water is delivered to the pure water high-level tank by the pure water pump. A certain amount of water is added to the carbonate back-extraction liquid mixing tank, and carbon dioxide is flushed into the mixing tank by the carbon dioxide tank area pump to prepare a carbonate solution, which is stored in the carbonate storage tank and then delivered to the carbonate high-level tank by the carbonate pump.

[0092] S2: Add caustic soda flakes to the rubidium-cesium material mixing tank to adjust the OH- concentration of the delivered rubidium-cesium material mixture to about 0.5N. Pump it to the high-level tank of rubidium-cesium material liquid and meter it into the separation extraction tank. At the same time, add the extractant, washing water and back-extraction acid into the extraction tank through the high-level tank of extractant, high-level tank of pure water and high-level tank of carbonate respectively for extraction.

[0093] After the loaded organic material passes through the washing section, it undergoes carbon dioxide back-extraction. The back-extraction solution is a cesium bicarbonate solution. The unloaded organic material after back-extraction is then acid-washed, water-washed, and regenerated before being reintroduced into the cesium extraction section for cesium extraction. After oil removal, the back-extraction solution is decomposed, filtered to remove calcium, and then deeply carbonized to obtain a cesium bicarbonate solution. The cesium bicarbonate solution is concentrated and centrifuged to obtain wet cesium bicarbonate. The mother liquor is recycled into the degreasing tank. The cesium bicarbonate is dried and decomposed to obtain the product cesium carbonate.

[0094] S3: Dissolve the cesium carbonate product in high-purity sulfuric acid to generate a cesium sulfate solution. Add high-purity aluminum sulfate and heat with ultrapure water to dissolve it to obtain high-purity cesium alum. Extract with selective extractants such as T-BAMBP crown ether to obtain a high-purity cesium carbonate solution. Concentrate under reduced pressure and cool to crystallize to obtain medical-grade cesium carbonate.

[0095] S4: Prepare a test sample from medical cesium carbonate for testing and analysis. The testing and analysis shall be performed in the spectral analysis device as described in any one of claims 1-8. The sample shall be placed in the support mechanism 6 and detected and analyzed by infrared spectroscopy emitted by the analysis mechanism 5.

[0096] Please refer to the reference again. Figures 1 to 11 The working principle of the spectral analysis device and the method for preparing medical cesium carbonate provided by the present invention is as follows:

[0097] Step S1: Place the cesium carbonate tablets made of medical grade into the respective bearing holes in the electric turntable 68, flip and close the cover plate 2, and then start the analyzer 1 to perform spectral detection on the cesium carbonate tablet sample.

[0098] During the closing process, the cover plate 2 will be subjected to downward force from the spring rod 53. The spring rod 53 drives the lifting frame 54 and the infrared generator 55 to descend. During the descent of the lifting frame 54, the inclined surface at the bottom can be used to control the guide wheel 57 to control the flip plate 56 to flip about the bottom hinge of the mounting sleeve 51. During the flipping process, the two flip plates 56 open to form an opening. At this time, the infrared generator 55 is fully exposed. After exposure, the infrared generator 55 emits penetrating infrared light into the medical cesium carbonate tablet sample.

[0099] Monochromatic infrared light is incident on an infrared detector, which converts the light intensity signal into an electrical signal and transmits it to a data processing unit. The data processing unit amplifies, filters, performs analog-to-digital conversion and Fourier transform on the electrical signal, calculates the absorbance at different wavenumbers, generates a complete infrared absorption spectrum of the sample to be tested, and stores it synchronously in the device database.

[0100] Step S2: After the test is completed, start the electric cylinder 65 to push the moving frame 66 to control the tilting frame 67 and the electric turntable 68 to push from the initial left side to the right side. During the pushing process, the positioning wheel 610 moves horizontally in the transverse groove 63 inside the slot plate 62.

[0101] When the moving frame 66 moves above the inclined groove 64, the connecting plate 69 follows and drives the positioning wheel 610 to adaptively move from the horizontal groove 63 to the inside of the inclined groove 64. During the movement of the positioning wheel 610, it will drive the connecting plate 69 to rotate clockwise. During the clockwise rotation of the connecting plate 69, it will drive the flipping frame 67 to flip clockwise inside the moving frame 66, thereby causing the electric turntable 68 to flip clockwise synchronously to assist in sample pressing and feeding.

[0102] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
