DETAILED DESCRIPTION

[0033] A protective container for packaging and transporting radioactive capsules, the explosion structure diagram of which is as follows Figure 1 As shown, the schematic diagram of the general assembly structure is as follows Figure 2 As shown, it includes an outer shell 1, a container shielding body 2, a capsule bottle 5, a capsule bottle cover 7, a container shielding body cover 9 and an outer shell cover 10, the container shielding body is clamped in the outer shell, the capsule bottle is placed in the container shielding body and temporarily locked with the container shielding body, the capsule bottle cover is covered on the capsule bottle, the container shielding body cover is covered on the container shielding body, and the container shielding body cover and the capsule bottle cover are temporarily locked, the container shielding body cover is clamped in the outer shell cover, and the outer shell cover is covered on the outer shell.

[0034] The radioactive capsule 6 is placed in the capsule bottle during storage and transportation. The overall structure of the protective container is relatively simple, and the volume after packaging is relatively small, which is convenient for storage and transportation. In addition, since the capsule bottle is placed in the container shielding body and temporarily locked with the container shielding body, the container shielding body cover and the capsule bottle cover are temporarily locked, the container shielding body cover is clamped in the outer shell cover and the outer shell cover is installed on the outer shell, and an interlocking cover assembly is achieved to prevent the capsule bottle from slipping out of the container shielding body and falling and being damaged during storage and transportation, causing drug dispersion, thereby ensuring the safety of the radioactive capsule during storage and transportation. When it is necessary to take the radioactive capsule, when the medical staff and the patient open the capsule bottle, there is no need for extra actions. They only need to open the outer shell cover, and then they can open the container shielding body cover and the capsule bottle cover together, take out the radioactive medicine and take it, which reduces the exposure time of the medical staff and the patient, and can ensure the safety of the radioactive capsule during taking.

[0035] The radioactive capsules here can also be oral liquids or radioactive substances such as seed sources.

[0036] Furthermore, the shell 1 includes a shell body 11 and a shell annular rib 12 arranged on the top of the shell body, the inner diameter of the shell annular rib is smaller than the inner diameter of the shell body and smaller than the outer diameter of the container shielding body, and the outer diameter of the lower part of the container shielding body cover is the same as the inner diameter of the shell annular rib.

[0037] When the container shielding body is placed into the shell body, the shell annular ribs will be squeezed outwards. After the container shielding body is placed into the shell body, the shell annular ribs rebound to limit the container shielding body, and the container shielding body cover can maintain a good seal after being buckled.

[0038] The specific shell structure diagram is as follows Figure 3 As shown, the shell can be a plastic shell, and the shell cover, the container shielding body cover and the capsule bottle cover are also made of plastic materials, specifically polypropylene materials, which are relatively light and not easy to be damaged, and are easy to process and manufacture. The thickness of the shell annular rib can be slightly thinner than the shell body, so that it has sufficient elasticity to be squeezed outward when the container shielding body is placed in the shell body. After the container shielding body is placed in place in the shell body, the shell annular rib rebounds to limit the container shielding body, so that the container shielding body is kept in the shell body and will not slide out, thereby ensuring the safety and stability of the protective container.

[0039] Furthermore, the inner wall of the shell is provided with a shell guide ridge 13, and the outer wall of the container shield is provided with a container shield guide groove 22 that cooperates with the shell guide ridge. When the container shield is packaged with the shell, the container shield guide groove is inserted into the shell guide ridge in a facing manner, which facilitates packaging positioning, and can further improve the stability of the container shield in the shell body, and prevent the container shield from rotating.

[0040] Schematic diagram of container shielding structure Figure 4As shown, the container shielding body can be made of lead-antimony alloy material, specifically 97% lead and 3% antimony alloy, to ensure that the container shielding body has a good shielding effect.

[0041] Optimally, the capsule bottle and the container shielding body are locked by the lower locking ring 3. The specific schematic diagram of the lower locking ring structure is as follows: Figure 5 As shown, the schematic diagram of the capsule bottle structure is as follows Figure 6 shown.

[0042] Further, the container shielding body 2 comprises a container shielding body main body 21 and a container shielding body flange 24 on the top of the container shielding body main body, the container shielding body main body is provided with a capsule bottle receiving cavity, the container shielding body flange and the inner wall of the capsule bottle receiving cavity are provided with a plurality of container shielding body grooves 23, and the outer wall of the lower locking ring is provided with a lower locking ring ridge 31 matching the container shielding body grooves.

[0043] Furthermore, a capsule bottle tab 51 is provided on the outer wall of the capsule bottle, and the lower locking ring is provided with a capsule bottle tab yielding locking groove 32, and the capsule bottle tab yielding locking groove includes a capsule bottle tab yielding portion 321 which is open at the top and vertically arranged, and an L-shaped capsule bottle tab locking portion 322 which is connected to the bottom of the capsule bottle tab yielding portion.

[0044] When the lower locking ring is packed, the ridge of the lower locking ring corresponds to the groove of the container shielding body, and the lower locking ring is inserted downward to the flange of the container shielding body. When the capsule bottle is placed in the container shielding body, the capsule bottle protrusion corresponds to the capsule bottle protrusion yielding part of the lower locking ring and then presses the capsule bottle downward. After the capsule bottle protrusion reaches the bottom of the capsule bottle protrusion yielding part, the capsule bottle is rotated to make the capsule bottle protrusion stuck in the capsule bottle protrusion locking part, that is, the capsule bottle and the container shielding body can be locked to prevent the capsule bottle from rotating or slipping out of the container shielding body and falling and being damaged during transportation, causing drug dispersion, thereby ensuring the safety of radioactive capsules during storage and transportation.

[0045] Furthermore, the capsule bottle is provided with a plurality of inwardly convex arc-shaped centering surfaces 52, the diameter of the inscribed circle of the arc-shaped centering surfaces being less than or equal to the diameter of the capsule bottle mouth, so as to prevent the radioactive capsule from shaking in the capsule bottle and to center the radioactive capsule. When the radioactive capsule is put into the capsule bottle, the radioactive capsule is put in along the arc-shaped centering surface, which has a centering effect on the radioactive capsule, preventing the radioactive capsule from shaking in the capsule bottle and avoiding jamming when pouring out the radioactive capsule.

[0046] Optimally, the container shielding body cover and the capsule bottle cover are locked by an upper locking ring 8. The specific upper locking ring structure diagram is as follows: Figure 7 As shown, the schematic diagram of the capsule bottle cap structure is as follows Figure 8 As shown, the schematic diagram of the container shielding cover structure is as follows Fig. 9 shown.

[0047] Furthermore, an upper locking ring ridge 81 is provided on the outer wall of the upper locking ring, and a container shielding body cover groove 92 matching the upper locking ring ridge is provided on the inner wall of the container shielding body cover.

[0048] Furthermore, a capsule bottle cap tab 71 is provided on the outer wall of the capsule bottle cap, and the upper locking ring is provided with a capsule bottle cap tab yielding locking groove 82, and the capsule bottle cap tab yielding locking groove includes a capsule bottle cap tab yielding portion 821 with an opening at the bottom and vertically arranged, and an L-shaped capsule bottle cap tab locking portion 822 connected to the bottom of the capsule bottle cap tab yielding portion.

[0049] When the locking ring is packaged, the ridge of the locking ring corresponds to the groove of the container shielding body cover, the upper locking ring is pressed into the container shielding body cover, the capsule bottle cap protrusion corresponds to the capsule bottle cap protrusion yielding part of the upper locking ring, and then the capsule bottle cap is pressed. After the capsule bottle cap protrusion reaches the bottom of the capsule bottle cap protrusion yielding part, the capsule bottle cap is rotated to make the capsule bottle cap protrusion stuck in the capsule bottle cap protrusion locking part, that is, the capsule bottle cap and the container shielding body cover can be locked, and then the container shielding body cover and the outer shell cover are clamped together, so that the capsule bottle cap, the container shielding body cover, and the outer shell cover are locked together to form a cover assembly. When the patient takes the radioactive capsule, it is only necessary to rotate the outer shell to open the cover assembly composed of the capsule bottle cap, the container shielding body cover, and the outer shell, so that only one conventional bottle opening and capping action is required to take out the capsule for taking, which can ensure the safety of the radioactive capsule during the taking process.

[0050] When testing radioactive capsules during storage or transportation, the combined cover assembly can be slightly rotated and then lifted upward to separate the capsule bottle cap from the cover assembly. Since the capsule bottle cap is made of plastic or other materials that do not have a shielding effect and can transmit the radiation emitted by the radioactive capsule, the radioactivity of the capsule can be tested without opening the capsule bottle cap, and the radioactive capsule can be taken by the patient after the decay meets the requirements, further improving the safety of the inspection process.

[0051] Furthermore, the outer wall of the container shielding cover is provided with a container shielding cover guide groove 91, and the inner wall of the outer shell cover is provided with an outer shell cover ridge 101 and an outer shell cover annular rib 102. The outer shell cover structure schematic diagram is shown in Fig.10 The annular rib of the outer shell cover has sufficient elasticity and is pressed outward when the container shielding body cover is placed into the outer shell cover. After the container shielding body cover is in place, the annular rib of the outer shell cover rebounds to limit the container shielding body cover so that the container shielding body cover is stably maintained in the outer shell cover. When the outer shell cover is rotated, the container shielding body cover will rotate together with the outer shell cover.

[0052] Furthermore, the capsule bottle receiving cavity is provided with an activated carbon pad 4, which can capture aerosols in the air and play a shock-absorbing role during transportation and transfer.

[0053] Preferably, the outer shell cover is connected to the outer shell by a threaded connection, the capsule bottle cover is connected to the capsule bottle by a threaded connection, and the container shielding body cover is buckled and connected to the container shielding body. When it is necessary to take radioactive capsules, when medical staff and patients open the capsule bottle, no extra actions are required. They only need to rotate the outer shell cover, and the container shielding body cover and the capsule bottle cover will also rotate together, so that the container shielding body cover and the capsule bottle cover are opened together, and the radioactive medicine can be taken out, which can ensure the safety of the radioactive capsules during the taking process. A plurality of anti-skid ridges can also be provided on the outer wall of the outer shell cover to prevent slipping when the outer shell cover is rotated.

[0054] The process of packaging radioactive capsules in protective containers is as follows: 1) Insert the container shielding body into the shell. During the insertion process, the annular rib at the open end of the shell is squeezed outward. After the container shielding body is packed in place, the annular rib rebounds to keep the container shielding body in the shell; 2) Align the ridge of the lower locking ring with the groove of the container shield, press down from the top surface of the flange of the container shield, and rivet it into the groove of the container shield with a slight interference fit; 3) Placing activated carbon pads at the bottom of the container shield to absorb radioactive aerosols in the container and to act as a buffer and shock absorber during transportation and transfer; 4) The capsule bottle tab slides downward along the capsule bottle tab yielding portion of the lower locking ring to reach the capsule bottle tab locking portion, and the capsule bottle is inserted into the container shielding body and locked; 5) Insert the container shielding body cover into the outer shell cover along the ridge of the outer shell cover. During the insertion process, the annular rib of the outer shell cover is pressed outward. After the package is in place, the annular rib of the outer shell cover rebounds to keep the container shielding body cover in the outer shell cover; 6) Align the ridge of the upper locking ring with the groove of the container shielding cover, press down from the concave surface of the container shielding cover, and slightly interfere with the rivet into the groove of the container shielding cover. After pressing into place, a small amount of adhesive can be applied to the outer surface of the upper locking ring. The double anti-slip effect of the adhesive and the interference fit can fix the upper locking ring in place to prevent it from falling off; 7) Slide the capsule bottle cap tab downward along the capsule bottle cap tab yielding portion of the upper locking ring to the capsule bottle cap tab locking portion, insert the capsule bottle cap into the container shielding body cover and lock it; 8) Place the radioactive capsule in the capsule bottle along the arc-shaped centering surface on the inner side of the capsule bottle, snap the outer shell cover of the packaged cover assembly onto the outer shell and tighten it, that is, the snapping between the container shielding body cover and the container shielding body and the tightening between the capsule bottle cover and the capsule bottle are completed at the same time, thereby completing the packaging.

[0055] The protective container of the radioactive capsule has a simple structure, a compact size, precise positioning, and is easy and quick to install, thereby enhancing the structural stability and facilitating storage and transportation. In addition, since the capsule bottle is placed in the container shielding body and temporarily locked with the container shielding body, the container shielding body cover and the capsule bottle cover are temporarily locked, the container shielding body cover is clamped in the outer shell cover and the outer shell cover is mounted on the outer shell, a cover assembly is formed, and interlocking is achieved, which can prevent the capsule bottle from slipping out of the container shielding body and falling and being damaged during storage and transportation, causing drug dispersion, thereby ensuring the safety of the radioactive capsule during storage and transportation.

[0056] The inspection process for protective containers of radioactive capsules is as follows: When it is necessary to test the radioactive capsule, the assembled cover assembly is slightly rotated to make the capsule bottle cover tab reach the capsule bottle cover tab yielding portion and then the cover assembly is lifted up to make the capsule bottle cover tab slide out of the capsule bottle cover tab yielding locking groove, thereby separating the capsule bottle cover from the cover assembly, and then the radioactivity of the radioactive capsule can be tested without opening the capsule bottle itself.

[0057] When testing radioactive capsules, the radioactivity of the capsules can be tested without opening the capsule bottle cap, and the radioactive capsules can be given to patients only after the decay reaches the requirement. This maintains the sterility and integrity of the capsule bottle, avoids the leakage of radioactive aerosols in the bottle, and improves the safety of the testing process.

[0058] The procedure for taking the radioactive capsules in protective containers is as follows: Since the capsule bottle cap tab is located at the capsule bottle cap tab locking portion at this time and the capsule bottle cap and the container shielding body cap are locked, the cover assembly, the outer shell cover, the container shielding body cover and the capsule bottle cap will rotate simultaneously until the outer shell cover is separated from the outer shell, the container shielding body cover is separated from the container shielding body, and the capsule bottle cap is also separated from the capsule bottle, and the radioactive capsule can be taken out for consumption.

[0059] Medical staff and patients do not need to make any extra movements when opening the capsule bottle. They only need to open the outer cover with a regular bottle opening and cap twisting action, and then they can open the container shielding body cover and the capsule bottle cover together to take out the capsule for consumption, which reduces the exposure time of medical staff and patients and ensures the safety of radioactive capsules during consumption.

[0060] In summary, the protective container for packaging and transporting radioactive capsules proposed by the present invention is not only easy to operate, but also can provide protection throughout the entire process of packaging, storage, transportation, testing, and taking, thereby improving the safety of the protective container for radioactive capsules throughout the entire process.
