[0002] During the production process of radionuclide products, it is necessary to send samples for inspection many times. For example, during the production process of sodium iodine

[131] oral solution, not only the radionuclide

[131] sample needs to be sent for inspection, but also the sodium iodine

[131] oral solution needs to be sent for inspection, and the finished product needs to be sent for inspection. At present, lead sample bottles are usually used to hold samples that need to be sent for inspection. Because of the presence of nuclear radiation, the sample bottles after the inspection need to be sealed when they are stored to prevent the aerosol carrying the radionuclide from spilling.

[0003] In the prior art, a sample bottle for delivering radioactive nuclides (such as iodine

[131] ) is covered with a top cover after use, and then a sealing cover is installed outside the top cover, and tape is wrapped around the interface between the sealing cover and the sample bottle to prevent the radioactive nuclide aerosol from escaping.

[0004] However, after a period of storage, the radioactivity of the nuclide decreases or disappears, and the tape needs to be removed to recover the sample bottle.

[0059] 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.

[0060] Embodiment 1:

[0061] Reference Figure 1-Figure 6 As shown, the radionuclide sample bottle storage container provided in this embodiment includes a lead barrel 100, a barrel cover 200, a first sealing member 400, a second sealing member 500 and a first driving mechanism 600, wherein:

[0062] The lead barrel 100 may include a barrel seat made of lead and a barrel body made of lead installed on the barrel seat. The top of the barrel body is penetrated to form a barrel mouth, and the barrel cover 200 covers the barrel mouth. Optionally, the barrel cover 200 can be installed at the barrel mouth by screwing, or connected to the top of the lead barrel 100 by a buckle structure. In order to prevent aerosol from flowing out of the gap between the barrel cover 200 and the top of the lead barrel 100, a rubber sealing ring 210 is also installed between the barrel cover 200 and the top of the lead barrel 100. A handle is also provided on the outer wall of the barrel body.

[0063] The barrel cover 200 is provided with an insertion tube 300 extending in the vertical direction, the insertion tube 300 is connected to the interior of the lead barrel 100, and the insertion tube 300 has a first end close to the inside of the lead barrel 100 and a second end close to the outside of the lead barrel 100. Specifically, the first end of the insertion tube 300 is placed inside the lead barrel 100, and the second end is placed outside the lead barrel 100. The insertion tube 300 is integrally formed with the barrel cover 200. Of course, the insertion tube 300 can also be fixedly connected to the barrel cover 200 by welding. The inner diameter of the insertion tube 300 is larger than the outer diameter of the sample bottle, so that the sample bottle can be completely placed in the insertion tube 300 vertically or lying flat.

[0064] The first sealing member 400 and the second sealing member 500 are detachably mounted on the insertion tube 300, respectively, wherein the first sealing member 400 is used to block the first end of the insertion tube 300, and the second sealing member 500 is used to block the second end of the insertion tube 300. The first driving mechanism 600 is connected to the first sealing member 400, and the first driving mechanism 600 is used to drive the first sealing member 400 to open and close the first end of the insertion tube 300. The second sealing member 500 can be directly controlled to open and close by the hands of the staff. In this case, the staff holds the second sealing member 500 by hand to control it to open and close the second end of the insertion tube 300. However, in this case, the hands of the staff need to directly contact the second sealing member 500. Since the second sealing member 500 may directly contact the sample bottle, there is also a certain risk of radioactivity. Therefore, the best implementation method of this embodiment is to use the second driving mechanism 700 to drive the second sealing member 500 to open and close the above-mentioned second end, that is, the second driving mechanism 700 is connected to the second sealing member 500. The staff only needs to operate the second driving mechanism 700 to drive the second sealing member 500 to open and close the second end of the above-mentioned insertion tube 300. In this way, the staff's hands can be prevented from directly contacting the above-mentioned second sealing member 500.

[0065] The use process is as follows: when it is necessary to put the used sample bottle into the storage container, first open the second sealing member 500 from the outside, then put the sample bottle into the insertion tube 300 from the second end, and then immediately install the second sealing member 500 at the second end of the insertion tube 300 to block the second end of the insertion tube 300. At this time, the sample bottle is overlapped on the first sealing member 400, and then the first driving mechanism 600 is used to drive the first sealing member 400 to open the first end of the insertion tube 300. Under the action of gravity, the sample bottle in the insertion tube 300 will automatically fall into the lead barrel 100, and finally the first driving mechanism 600 is used to drive the first sealing member 400 to close the first end of the insertion tube 300. In this way, the first end of the insertion tube 300 is sealed by the first sealing member 400, and the second end is blocked by the second sealing member 500.

[0066] Through the above structure, the storage container provided in this embodiment can not only centrally store the sample bottles used for the nuclide sample delivery, but also effectively reduce the storage space when there are many sample bottles. Moreover, the storage container can realize double blocking with the help of the first sealing member 400 and the second sealing member 500, so as to more effectively prevent the aerosol containing nuclides in the lead barrel 100 from overflowing, and the stability and safety of use are higher, and the blocking does not need to be wrapped with tape. Moreover, in the process of putting the sample bottle into the lead barrel 100, there is always a sealing member to block the insertion tube 300, so that in the process of putting the sample bottle, the aerosol in the lead barrel 100 will not overflow from the insertion tube 300, and the use safety is higher. When the storage time of the sample bottle reaches the safety period, the radioactivity of the sample bottle is reduced to a weak level, or even no radioactivity. At this time, the non-radioactive sample bottle in the lead barrel 100 can be taken out by opening the barrel cover 200. Therefore, with the help of the storage container, the used sample bottles can be handled more safely, conveniently and efficiently.

[0067] Optionally, the first sealing member 400 in the present embodiment includes a first hard plate 410 and a first silicone plate 420. A first receiving groove is provided on one side surface of the first hard plate 410, and the first silicone plate 420 is embedded and fixed in the above-mentioned first receiving groove. Specifically, the first silicone plate 420 can be fixed in the first receiving groove by bonding, and the first silicone plate 420 can cover the first end of the above-mentioned insertion tube 300. The first driving mechanism 600 is connected to the first hard plate 410, and the first driving mechanism 600 can drive the hard plate to drive the first silicone plate 420 to approach or move away from the first end of the insertion tube 300, and when the first hard plate 410 moves to the first end close to the insertion tube 300, the first silicone plate 420 and the first end are attached to block the first end, and when the first hard plate 410 moves away from the position close to the first end, the first sealing member 400 composed of the first silicone plate 420 and the first hard plate 410 cannot block the first end of the insertion tube 300, and at this time, the first end of the insertion tube 300 is opened. The provision of the first silicone plate 420 can achieve a better sealing effect when blocking the first end.

[0068] Optionally, the first driving mechanism 600 in this embodiment includes a first bracket 610 and a lifting driving structure, wherein:

[0069] The first bracket 610 includes a connecting rod 611 and a swing plate 612. A through hole is opened at one end of the swing plate 612. The connecting rod 611 is inserted into the through hole, and the connecting rod 611 is perpendicular to the swing plate 612. Two fastening nuts 613 are screwed on the connecting rod 611. The two fastening nuts 613 are respectively located on both sides of the swing plate 612. In this way, the two fastening nuts 613 can clamp the swing plate 612 on both sides, thereby fixing the connecting rod 611 on the swing plate 612. At this time, the end of the connecting rod 611 away from the swing plate 612 serves as one end of the first bracket 610, and the end of the connecting rod 611 away from the swing plate 612 is connected to the other side plate surface of the above-mentioned first hard plate 410. A support 310 is provided on the outer wall of the insertion tube 300, and a protrusion is fixedly provided in the middle of the swing plate 612, and the protrusion is the middle of the first bracket 610. The protrusion is hinged to the support 310. At this time, the first bracket 610 constitutes a lever structure for driving the first sealing member 400 to rotate, and the fulcrum of the lever is the hinged part of the protrusion and the support 310. The other end of the swing plate 612 constitutes the other end of the first bracket 610.

[0070] The lifting drive structure is installed on the barrel cover 200, and the lifting end of the lifting drive structure is hinged to the other end of the swing plate 612. When the lifting drive structure drives the other end of the first bracket 610 to rise and fall, the first bracket 610 drives the first hard plate 410 to rotate around the fulcrum, thereby driving the first hard plate 410 to move closer to or away from the first end. Specifically, the lifting drive structure includes a lifting shaft 620, a first connecting rod 630 and a first handle 640, wherein:

[0071] The lifting shaft 620 is a straight rod. The barrel cover 200 is provided with a through hole. The lifting shaft 620 is inserted into the through hole in a sliding manner. The bottom end of the lifting shaft 620 is placed in the lead barrel 100 and is hinged to the other end of the swing plate 612 (that is, the other end of the first bracket 610). The top end of the lifting shaft 620 is located above the barrel cover 200. One end of the first connecting rod 630 is hinged to the top end of the lifting shaft 620, and the other end of the first connecting rod 630 is hinged to the middle of the first handle 640. A fixing frame 650 is fixedly installed on the top surface of the barrel cover 200. One end of the first handle 640 is hinged to the fixing frame 650. In this way, when the staff rotates the other end of the first handle 640, the first handle 640 can be rotated around the hinged portion of the fixing frame 650, and then the lifting shaft 620 is driven to rise and fall through the first connecting rod 630.

[0072] When the other end of the first handle 640 is lifted to the extreme, the lifting shaft 620 rises to the highest point, and the first sealing member 400 is driven to rotate downward to the lowest point through the swing plate 612 and the connecting rod 611. At this time, the first sealing member 400 is away from the first end of the insertion tube 300.

[0073] When the other end of the first handle 640 is pressed downward to the extreme, the lifting shaft 620 drops to the lowest point, and the first sealing member 400 is driven to rotate downward to the highest point through the swing plate 612 and the connecting rod 611. At this time, the first silicone plate 420 of the first sealing member 400 is tightly attached to the first end surface of the insertion tube 300. In this case, if a sample bottle is placed on the first sealing member 400, the weight of the sample bottle may drive the first sealing member 400 and the first bracket 610 to move downward. However, in actual situations, by setting the position of the protrusion on the swing plate 612 so that the distance between the protrusion and the connecting rod 611 is smaller than the distance between the protrusion and the lifting shaft 620, the first sealing member 400 will not be pressed by the sample bottle to open the first end. Of course, the lifting shaft 620 can also be set as a solid shaft with a heavier mass. When the lifting shaft 620 drops to the lowest point, the gravity of the sample bottle is not enough to overcome the gravity of the lifting shaft 620, so that the lifting shaft 620 rises, thereby preventing the first sealing member 400 from being pressed by the sample bottle to open the first end.

[0074] A silicone sleeve is sleeved on the first handle 640 to make the first handle 640 feel better.

[0075] In order to enable the lifting shaft 620 to be lifted and lowered more smoothly and stably, in this embodiment, a guide sleeve 651 is further provided on the above-mentioned fixed frame 650, and the above-mentioned lifting shaft 620 is inserted into the above-mentioned guide sleeve 651 so as to slide up and down, so that the guide sleeve 651 is used to guide the lifting and lowering of the lifting shaft 620.

[0076] Preferably, since the lifting shaft 620 will enter the lead barrel 100 and come into direct contact with the aerosol in the lead barrel 100, if there are no protective measures, when the lifting shaft 620 rises and causes the section of the lifting shaft 620 originally located in the lead barrel 100 to rise above the barrel cover 200, the aerosol attached to the outer wall of the lifting shaft 620 may also cause pollution to the environment. Therefore, in this embodiment, a sealing ring is provided in the above-mentioned through hole, and the lifting shaft 620 is inserted into the inner hole of the sealing ring, and the outer wall of the lifting shaft 620 is in contact with the outer wall of the sealing ring. In this way, not only can the sealing ring be used to seal the gap between the outer wall of the lifting shaft 620 and the inner wall of the through hole, but also, when the lifting shaft 620 rises, the sealing ring can scrape off the aerosol attached to the outer wall of the lifting shaft 620 to prevent the aerosol from moving with the lifting shaft 620 to the outside of the lead barrel 100.

[0077] Optionally, the second sealing member 500 in this embodiment includes a second hard plate 510 and a second silicone plate 520. A second receiving groove is opened on one side of the second hard plate 510, and the second silicone plate 520 is embedded and fixed in the second receiving groove. Specifically, the second silicone plate 520 can be fixed in the second receiving groove by bonding, and the second silicone plate 520 can cover the second end of the above-mentioned insertion tube 300. Moreover, when the second silicone plate 520 is in contact with the second end face of the insertion tube 300, the second sealing member 500 blocks the second end of the above-mentioned insertion tube 300.

[0078] As the best implementation of this embodiment, as described above, the second sealing member 500 is connected to the second driving mechanism 700, so that the second driving mechanism 700 is used to drive the second sealing member 500 to open and close the second end of the above-mentioned insertion tube 300. In fact, the second driving mechanism 700 is connected to the second hard plate 510, and the second driving mechanism 700 is used to drive the second hard plate 510 to approach or move away from the second end of the above-mentioned insertion tube 300. When the second hard plate 510 approaches the second end of the insertion tube 300, the second silicone plate 520 fits with the above-mentioned second end to block the second end of the insertion tube 300. The provision of the second silicone plate 520 makes the sealing effect of the second sealing member 500 better when blocking the second end. When the second hard plate 510 moves away from the position close to the second end of the insertion tube 300, the second silicone plate 520 is separated from the second end of the insertion tube 300, and the second sealing member 500 composed of the second silicone plate 520 and the second hard plate 510 cannot block the second end of the insertion tube 300. At this time, the second end of the insertion tube 300 is open.

[0079] Optionally, the second driving mechanism 700 in this embodiment includes a second bracket 710 and a yaw driving structure, wherein:

[0080] The second bracket 710 includes a connecting column 711 and a swing arm 712. The connecting column 711 is installed at one end of the swing arm 712. At this time, the connecting column 711 constitutes one end of the second bracket 710. The connecting column 711 is perpendicular to the swing arm 712, and the end of the connecting column 711 away from the swing arm 712 is connected to the other side of the second hard plate 510. In this embodiment, a hinge seat 720 is also installed on the top surface of the barrel cover 200, and the end of the swing arm 712 away from the connecting column 711 (that is, the other end of the second bracket 710) is hinged to the hinge seat 720. In this way, the swing arm 712 is driven to rotate around the position where it is hinged with the hinge seat 720, so that the second hard plate 510 can be driven to drive the second silicone plate 520 to approach or move away from the second end of the insertion tube 300 through the connecting column 711. Specifically, when the swing arm 712 rotates toward the side of the insertion tube 300, the second silicone plate 520 is driven to approach the second end of the insertion tube 300. If it is rotated to the extreme position toward the side of the insertion tube 300, the second silicone plate 520 is tightly fitted with the second end of the insertion tube 300; when the swing arm 712 rotates away from the insertion tube 300, the second sealing member 500 is driven away from the second end of the insertion tube 300.

[0081] The yaw drive structure includes a second connecting rod 730 and a second handle 740. One end of the second handle 740 is hinged to the middle of the swing arm 712 (i.e., the middle of the second bracket 710). Thus, by pulling the second handle 740, the swing arm 712 can be rotated, i.e., the second bracket 710 is driven to drive the second sealing member 500 to rotate. One end of the second connecting rod 730 is hinged to the middle of the second handle 740, and the other end of the second connecting rod 730 is hinged to the hinge seat 720. Moreover, the hinge position of the second connecting rod 730 and the hinge seat 720 is different from that of the second bracket 710. Thus, the second connecting rod 730 can limit the moving range of the second handle 740. However, when the second handle 740 is pulled, the effect of driving the swing arm 712 to rotate can still be achieved. In this way, the yaw drive structure is connected to the second bracket 710, and is used to drive the second bracket 710 to swing around the above-mentioned hinge seat 720, and when the yaw drive structure drives the second bracket 710 to drive the second hard plate 510 to swing, the second silicone plate 520 approaches or moves away from the second end of the above-mentioned insertion tube 300.

[0082] Optionally, a fixing seat 750 may be provided on the top surface of the barrel cover 200, and the hinge seat 720 may be bolted to the top of the fixing seat 750. In this embodiment, a long through slot extending along the length direction thereof is provided on the swing arm 712, the connecting column 711 is inserted into the long through slot, and the connecting column 711 may slide in the long through slot along the length direction of the long through slot, two locking nuts 713 are screwed on the connecting column 711, and the two locking nuts 713 are respectively provided on both sides of the swing arm 712, when the two locking nuts 713 are both in close contact with the swing arm 712, the connecting column 711 is locked on the swing arm 712, when one or both of the locking nuts 713 are loosened, the connecting column 711 may slide in the long through slot to change the specific position of the connecting column 711 and the second sealing member 500 connected thereto on the swing arm 712.

[0083] Of course, the hinged seat 720 can also be rotatably installed on the top of the fixed seat 750 through a turntable. In this case, when the second handle 740 is manipulated to drive the second sealing member 500 to open the second end of the insertion tube 300, the hinged seat 720 can be rotated to move the second sealing member 500 and the second bracket 710 away, so that the sample bottle can be smoothly placed from the second end into the above-mentioned insertion tube 300.

[0084] A silicone sleeve is also provided on the second handle 740 to make the second handle 740 feel better.
