Description
Technical Field
[0001] The utility model relates to the technical field of radioactive drug protection containers, in particular to a protection container for packaging and transporting radioactive capsules. Background Art
[0002] Radiopharmaceutical capsules, such as radioactive iodine-131 capsules, are typically stored and transported in resealable protective containers due to the radioactivity of iodine-131. Currently, these protective containers consist of an inner sealed container containing the capsules. This container, typically a vial or plastic bottle, meets medical sterility requirements but does not shield radiation, and is also protected by an outer protective container that also shields radiation. When using radiopharmaceutical capsules in medical institutions, the protective container must first be opened, the inner sealed container (i.e., the vial or plastic bottle) containing the capsules removed from the outer protective container, and then the lid of the inner sealed container must be opened to remove the capsules for oral administration. This process requires two steps of opening the package, exposing both the operator and the patient to a certain degree of radiation exposure. Removing the radioactive capsules is complex and carries the risk of exposure to radioactive material. Furthermore, because there is no interlocking mechanism between the inner sealed container and the outer protective container, there is a risk of the inner sealed container slipping out of the protective container and breaking, potentially causing drug dispersion.

DETAILED DESCRIPTION
[0036] A protective container for packaging and transporting radioactive capsules, the explosion structure of which is shown in the following figure Figure 1 As shown, the overall assembly structure diagram is as follows Figure 2 As shown, it includes a shell 1, a container shielding body 2, a capsule bottle 5, a capsule bottle cap 7, a container shielding body cap 9 and a shell cap 10, the container shielding body is clamped in the shell, the capsule bottle is placed in the container shielding body and temporarily locked with the container shielding body, the capsule bottle cap is mounted on the capsule bottle, the container shielding body cap is mounted on the container shielding body, and the container shielding body cap and the capsule bottle cap are temporarily locked, the container shielding body cap is clamped in the shell cap, and the shell cap is mounted on the shell.
[0037] During storage and transportation, the radioactive capsule 6 is placed in a capsule bottle. The overall structure of the protective container is relatively simple, and the packaged volume is relatively compact, making it convenient for storage and transportation. Furthermore, because the capsule bottle is placed within the container shield and temporarily locked to the container shield, the container shield cover is temporarily locked to the capsule bottle cap, and the container shield cover is clipped into the outer shell cover, and the outer shell cover is mounted on the outer shell, an interlocking lid assembly is achieved. This prevents the capsule bottle from slipping out of the container shield and falling, causing damage and drug dispersion during storage and transportation, thereby ensuring the safety of the radioactive capsule during storage and transportation. When the radioactive capsule is to be taken, the medical staff and the patient can open the capsule bottle without any unnecessary steps. They only need to open the outer shell cover, which then opens the container shield cover and the capsule bottle cap together, remove the radioactive drug, and take it. This reduces the exposure time of the medical staff and the patient, and ensures the safety of the radioactive capsule during administration.
[0038] The radioactive capsules herein may also be oral solutions or radioactive substances such as seed sources.
[0039] Furthermore, the housing 1 includes a housing body 11 and a housing annular rib 12 provided on the top of the housing body. The inner diameter of the housing annular rib is smaller than the inner diameter of the housing body and smaller than the outer diameter of the container shield. The outer diameter of the lower portion of the container shield cover is the same as the inner diameter of the housing annular rib.
[0040] 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.
[0041] The specific shell structure diagram is as follows Figure 3 As shown, the outer shell can be a plastic shell, and the outer shell cover, container shield cover, and capsule bottle cap are also made of plastic materials, specifically polypropylene, which is relatively lightweight, unbreakable, and easy to manufacture. The outer shell annular rib can be slightly thinner than the outer shell body, providing sufficient elasticity to be squeezed outward when the container shield is inserted into the outer shell body. Once the container shield is properly positioned within the outer shell body, the outer shell annular rib rebounds to retain the container shield in place, preventing it from slipping out and ensuring the safety and stability of the protective container.
[0042] Furthermore, the inner wall of the outer shell is provided with an outer 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 outer shell guide ridge. When the container shield is packaged with the outer shell, the container shield guide groove and the outer shell guide ridge are inserted into the container shield, which facilitates packaging positioning and further improves the stability of the container shield within the outer shell body, preventing the container shield from rotating.
[0043] Schematic diagram of the 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.
[0044] Optimized, the capsule bottle and the container shielding body are locked by the lower locking ring 3, and the specific lower locking ring structure diagram is as follows Figure 5 As shown, the schematic diagram of the capsule bottle structure is as follows Figure 6 shown.
[0045] Furthermore, the container shield 2 includes a container shield body main body 21 and a container shield body flange 24 on the top of the container shield body main body. The container shield body main body is provided with a capsule bottle receiving cavity. The container shield body flange and the inner wall of the capsule bottle receiving cavity are provided with a plurality of container shield body grooves 23. The outer wall of the lower locking ring is provided with a lower locking ring ridge 31 that matches the container shield body grooves.
[0046] 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 and locking groove 32, and the capsule bottle tab yielding and locking groove includes a capsule bottle tab yielding portion 321 with an open top and vertically arranged, and an L-shaped capsule bottle tab locking portion 322 connected to the bottom of the capsule bottle tab yielding portion.
[0047] When the lower locking ring is packaged, 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 so that the capsule bottle protrusion is 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 diffusion, thereby ensuring the safety of radioactive capsules during storage and transportation.
[0048] Furthermore, the capsule bottle is provided with a plurality of inwardly convex arcuate centering surfaces 52, the inscribed diameter of which is less than or equal to the diameter of the capsule bottle mouth. This prevents the radioactive capsule from swaying within the capsule bottle and serves to center the radioactive capsule. When the radioactive capsule is placed into the capsule bottle, it is placed along the arcuate centering surfaces, which serves to center the radioactive capsule, preventing it from swaying within the capsule bottle and preventing it from jamming when being poured out.
[0049] Optimally, the container shield 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 capsule bottle cap structure diagram is as follows Figure 8 As shown, the schematic diagram of the container shield cover structure is as follows Figure 9 shown.
[0050] Furthermore, an upper locking ring ridge 81 is provided on the outer wall of the upper locking ring, and a container shielding cover groove 92 matching the upper locking ring ridge is provided on the inner wall of the container shielding cover.
[0051] 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 and locking groove 82, and the capsule bottle cap tab yielding and locking groove includes a capsule bottle cap tab yielding portion 821 with an open 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.
[0052] When the locking ring is packaged, the ridge of the upper locking ring corresponds to the groove of the container shielding body cover, and 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 so that the capsule bottle cap protrusion is 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, he only needs to rotate the outer shell to open the cover assembly consisting of the capsule bottle cap, the container shielding body cover and the outer shell, so that the capsule can be taken out and taken with just one conventional bottle opening and capping action, which can ensure the safety of the radioactive capsule during the taking process.
[0053] When testing radioactive capsules during storage or transportation, the assembled 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. The radioactive capsule can be taken by the patient after the decay meets the requirements, further improving the safety of the testing process.
[0054] Furthermore, the outer wall of the container shield cover is provided with a container shield cover guide groove 91, and the inner wall of the shell cover is provided with a shell cover ridge 101 and a shell cover annular rib 102. The shell cover structure diagram is shown in FIG. Figure 10 As shown, the outer shell cover's annular ribs are sufficiently elastic to be squeezed outward when the container shielding body cover is placed into the outer shell cover. Once the container shielding body cover is in place, the outer shell cover's annular ribs rebound to hold the container shielding body cover in place, keeping the container shielding body cover stably within the outer shell cover. When the outer shell cover is rotated, the container shielding body cover rotates with the outer shell cover.
[0055] 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.
[0056] Preferably, the outer shell cover is threadedly connected to the outer shell, the capsule bottle cover is threadedly connected to the capsule bottle, and the container shield cover is snap-fitted to the container shield. When the radioactive capsule is to be administered, the patient or medical professional can open the capsule bottle without any additional steps. Simply rotating the outer shell cover will cause the container shield cover and the capsule bottle cover to rotate together, allowing the radiopharmaceutical to be removed and administered. This ensures the safety of the radioactive capsule during administration. Multiple anti-slip ridges can also be provided on the outer wall of the outer shell cover to prevent slipping during rotation of the outer shell cover.
[0057] The process of packaging radioactive capsules in protective containers is as follows:
[0058] 1) Insert the container shield into the shell. During the insertion process, the annular rib at the open end of the shell is squeezed outward. After the container shield is packed in place, the annular rib rebounds to keep the container shield in the shell.
[0059] 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;
[0060] 3) Placing activated carbon pads at the bottom of the container shield to absorb radioactive aerosols in the container and act as a buffer during transportation and transfer;
[0061] 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, inserting the capsule bottle into the container shielding body and locking it;
[0062] 5) Insert the container shield 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 squeezed outward. After the package is in place, the annular rib of the outer shell cover rebounds to keep the container shield cover in the outer shell cover;
[0063] 6) Align the ridge of the upper locking ring with the groove of the container shield cover, press down from the concave surface of the container shield cover, and rivet it into the groove of the container shield cover with a slight interference fit. After pressing it into place, a small amount of adhesive can be applied to the outer surface of the upper locking ring. The dual anti-slip effect of the adhesive and the interference fit will fix the upper locking ring in place and prevent it from falling off;
[0064] 7) Slide the capsule cap tab downward along the capsule cap tab yielding portion of the upper locking ring to the capsule cap tab locking portion, insert the capsule cap into the container shielding cover and lock it;
[0065] 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, thus simultaneously completing 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, thereby completing the packaging.
[0066] The protective container for radioactive capsules features a simple structure, compact size, precise positioning, and quick and easy installation, enhancing structural stability and facilitating storage and transportation. Furthermore, because the capsule bottle is placed within the container shield and temporarily locked to the container shield, the container shield cover is temporarily locked to the capsule bottle cap, and the container shield cover is snap-fitted into the outer shell cover, which in turn is mounted on the outer shell, forming a cover assembly that interlocks. This prevents the capsule bottle from slipping out of the container shield during storage and transportation, falling, and breaking, potentially causing drug dispersion. This ensures the safety of the radioactive capsules during storage and transportation.
[0067] The inspection process for protective containers of radioactive capsules is as follows:
[0068] When it is necessary to test the radioactive capsule, the assembled cover assembly is slightly rotated so that the capsule bottle cap tab reaches the capsule bottle cap tab yielding portion and then the cover assembly is lifted up to make the capsule bottle cap tab slide out of the capsule bottle cap tab yielding locking groove, thereby separating the capsule bottle cap from the cover assembly. Then, the radioactivity of the radioactive capsule can be tested without opening the capsule bottle itself.
[0069] When testing radioactive capsules, the radioactivity of the capsules can be tested without opening the capsule bottle cap. The radioactive capsules can be given to patients only after the decay reaches the required level. This maintains the sterility and integrity of the capsule bottle, avoids leakage of radioactive aerosols in the bottle, and improves the safety of the testing process.
[0070] The procedure for taking the radioactive capsules in protective containers is as follows:
[0071] At this time, since the capsule bottle cap tab is located at the capsule bottle cap tab locking portion and locks the capsule bottle cap and the container shielding body cover, the cover assembly is rotated, and the outer shell cover, the container shielding body cover and the capsule bottle cap 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.
[0072] When opening the capsule bottle, medical staff and patients do not need to perform any extra actions. 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. This reduces the exposure time of medical staff and patients and ensures the safety of radioactive capsules during consumption.
[0073] In summary, the protective container for packaging and transporting radioactive capsules proposed in the present invention is not only easy to operate, but also can provide protection throughout the entire process of packaging, storage, transportation, testing, and administration, thereby improving the safety of the protective container for radioactive capsules throughout the entire process.
