Abstract
Description
Technical Field
[0001] This utility model relates to the field of design technology of protective devices for artificial nuclide injection, and in particular to a portable and precise dispensing and injection protective device for radionuclide drugs. Background Technology
[0002] Currently, the packaging of artificial radionuclide drugs is carried out using large horizontal packaging machines, medium-sized vertical packaging cabinets, and small tabletop packaging stations. However, these packaging devices are not portable and cannot meet the needs of packaging and injecting artificial radionuclide drugs into non-radioactive drug-specific injection sites.
[0003] Chinese Patent Publication No. CN209747142U discloses a portable and precise dispensing and injection protective device for artificial radionuclide drugs. The device is characterized by a shielded container with an upper-opening storage tank for an artificial radionuclide drug vial in the middle. The upper-opening storage tank is fitted with a shielding cap that engages with it. The shielding cap has a slanted insertion hole for a suction needle and a slanted insertion hole for a venting needle, corresponding to the rubber stopper opening of the artificial radionuclide drug vial inside the upper-opening storage tank. A shielding cap is provided on the shielding cap to cover it. The shielded container is equipped with an adjustable and locking universal support mechanism for adjusting and locking the tilt direction and angle of the container. At least in the area surrounding the slanted insertion hole of the suction needle, the shielding cap has a vertical surface with a horizontal bubble, perpendicular to the axis of the slanted insertion hole.
[0004] While it meets the requirements for portability and existing ward, outpatient, and mobile injection procedures, a significant safety hazard exists: after piercing the rubber stopper with a needle to extract the medication, the medication leaks through the puncture hole into the shielding cap during transport. When the cap is opened, the medication spills out, posing a serious safety risk. Therefore, there is an urgent need to design a portable, precise, and protective device for the injection of radionuclide drugs to address these issues. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a portable and precise dispensing and injection protective device for radionuclide drugs. It has the advantage of being able to seal the rubber stopper hole punctured by the needle after drug dispensing, thus solving the problem of easy leakage after drug dispensing in existing portable and precise dispensing and injection protective devices for radionuclide drugs.
[0006] This invention is implemented as follows: a portable and precise dispensing and injection protective device for radionuclide drugs includes a shielding container and a drug storage container placed inside the shielding container. The top of the drug storage container is provided with a cap, and the top wall of the cap has a receiving cavity. A rubber stopper is placed inside the receiving cavity. When dispensing the drug, a needle pierces the rubber stopper to reach the inside of the drug storage container. A blind hole is provided at the upper center of the rubber stopper to facilitate needle piercing. A threaded cylinder is integrally formed on the upper part of the drug storage container. A shielding cap is threadedly connected to the outside of the threaded cylinder. A compression part is integrally formed at the inner center of the shielding cap, and a sealing plate is provided between the compression part and the rubber stopper.
[0007] As a preferred embodiment of this utility model, the top of the blind hole is provided with a flared portion, and the bottom center of the sealing plate is integrally formed with a conical portion that abuts against the flared portion.
[0008] As a preferred embodiment of this utility model, the threaded cylinder is provided with a guide rod inside. The guide rod includes a square column portion fixedly connected to the upper wall of the shielding tank and a cylindrical portion located above the square column portion. A square hole is provided on the sealing plate for the square column portion to pass through. The diameter and width of the cylindrical portion are equal to the width of the square column portion.
[0009] As a preferred embodiment of this utility model, a spring is fixedly connected to the upper wall of the shielding tank, the top of the spring abuts against the sealing plate, and the height of the spring and the square column are equal to the height of the threaded cylinder.
[0010] As a preferred embodiment of this invention, a limiting part is fixedly connected to the top of the cylindrical part, and the diameter of the limiting part is larger than the diameter of the cylindrical part.
[0011] As a preferred embodiment of the present invention, the side wall of the shielding container is provided with a handle, and the number of handles is two, and the two handles are symmetrically located on the outer side wall of the shielding container.
[0012] As a preferred embodiment of this utility model, the bottom of the shielding tank is integrally formed with a base, and the diameter and length of the base gradually increase from top to bottom.
[0013] As a preferred embodiment of this utility model, a carrying rope is fixedly connected to the upper surface of the two handles, and an anti-slip sleeve is fitted over the middle of the carrying rope.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, by setting up a shielded container, a medicine storage container, a threaded cylinder, a shielded cover, a bottle cap, a receiving cavity, a rubber stopper, a blind hole, a sealing plate, and a squeezing part, enables the needle to be inserted into the medicine storage container with the blind hole aligned with it when taking medicine. After the blind hole is punctured, the medicine is extracted. After the medicine is taken out, when the shielded cover and the threaded cylinder are tightened, the squeezing part inside the shielded cover squeezes the sealing plate downward to seal the blind hole of the rubber stopper, preventing the medicine from leaking out.
[0016] 2. By providing a flared part and a conical part, this utility model enables the flared part and the conical part to interlock, which can further ensure the sealing of the punctured blind hole.
[0017] 3.

[0032] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0033] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0034] like Figures 1 to 8 As shown, this utility model discloses a portable and precise dispensing and injection protective device for radionuclide drugs, comprising a shielding container 1 and a drug storage container 2 placed inside the shielding container 1. The top of the drug storage container 2 is provided with a cap 4, and the top wall of the cap 4 is provided with a receiving cavity 5. A rubber stopper 6 is provided inside the receiving cavity 5. When dispensing the drug, a needle pierces the rubber stopper 6 to reach the inside of the drug storage container 2. A blind hole 7 is provided at the upper center of the rubber stopper 6 to facilitate needle piercing. A threaded cylinder 101 is integrally formed on the upper part of the drug storage container 2. A shielding cover 3 is threadedly connected to the outside of the threaded cylinder 101. A compression part 301 is integrally formed at the inner center of the shielding cover 3. A sealing plate 8 is provided between the compression part 301 and the rubber stopper 6.
[0035] The above solution, by setting up a shielded container 1, a medicine storage container 2, a threaded cylinder 101, a shielded cover 3, a bottle cap 4, a receiving cavity 5, a rubber stopper 6, a blind hole 7, a sealing plate 8, and a squeezing part 301, allows the needle to be inserted into the medicine storage container 2 with the blind hole 7 aligned with it when taking medicine. After the blind hole 7 is punctured, the medicine is extracted. After the medicine is taken out, when the shielded cover 3 and the threaded cylinder 101 are tightened, the squeezing part 301 inside the shielded cover 3 squeezes the sealing plate 8 downward to seal the blind hole 7 of the rubber stopper 6, preventing the medicine from leaking out.
[0036] refer to Figure 5 The top of the blind hole 7 is provided with a flared part 701, and the bottom center of the sealing plate 8 is integrally formed with a conical part 801 that abuts against the flared part 701.
[0037] By adopting the above solution, by setting the flared part 701 and the conical part 801, the flared part 701 and the conical part 801 can be interlocked, which can further ensure the sealing of the punctured blind hole 7.
[0038] refer to Figure 6 and Figure 8 The threaded cylinder 101 is provided with a guide rod 9 inside. The guide rod 9 includes a square column portion 901 fixedly connected to the upper wall of the shielding tank 1 and a cylindrical portion 902 provided on the upper part of the square column portion 901. The sealing plate 8 is provided with a square hole 802 for the square column portion 901 to pass through. The diameter and width of the cylindrical portion 902 are equal to the width of the square column portion 901.
[0039] The above solution, by setting guide rod 9, cylindrical part 902, square column part 901 and square hole 802, can prevent the sealing plate 8 from rotating when the square hole 802 of the sealing plate 8 is engaged with the square column part 901, so that the axis of the sealing plate 8 always coincides with the axis of the rubber plug 6, ensuring that the conical part 801 can be aligned with the flared part 701. When the cylindrical part 902 is engaged with the square hole 802, the guide rod 9 disengages from the anti-rotation effect on the sealing plate 8, so that the sealing plate 8 can rotate to one side of the threaded cylinder 101 without affecting the drug dispensing process.
[0040] refer to Figure 6 and Figure 8 A spring 10 is fixedly connected to the upper wall of the shielding tank 1. The top of the spring 10 abuts against the sealing plate 8. The height of the spring 10 and the square column 901 are equal to the height of the threaded cylinder 101.
[0041] By adopting the above solution, by setting the cylindrical part 902 and the spring 10, when the shielding cover 3 is unscrewed from the threaded cylinder 101, as the shielding cover 3 rises, the sealing plate 8 is squeezed and raised by the spring 10. When the shielding cover 3 is completely removed, the sealing plate 8 is just at the position where it is disengaged from the square column part 901, and the sealing plate 8 can be directly rotated to the side above the rubber stopper 6 to remove the medicine.
[0042] refer to Figure 6 and Figure 8 The top of the cylindrical portion 902 is fixedly connected to a limiting portion 903, and the diameter of the limiting portion 903 is larger than the diameter of the cylindrical portion 902.
[0043] By adopting the above solution, the sealing plate 8 can be prevented from separating from the guide rod 9 by setting the limiting part 903.
[0044] refer to Figure 1 The shielding container 1 is provided with a handle 11 on its side wall. There are two handles 11, and the two handles 11 are symmetrical on the outer side wall of the shielding container 1.
[0045] The above solution is adopted: by setting two handles 11, it is possible to hold the handles 11 with both hands to pick up and put down the shielded container 1, which is safer and reduces the shaking of the medicine in the storage container 2.
[0046] refer to Figure 1 The bottom of the shielding tank 1 is integrally formed with a base 13, and the diameter and length of the base 13 gradually increase from top to bottom.
[0047] By adopting the above solution, the shielding container 1 can be made more stable during placement by setting the base 13.
[0048] refer to Figure 1 The upper surfaces of the two handles 11 are fixedly connected with a carrying rope 12, and the middle part of the carrying rope 12 is fitted with an anti-slip sleeve 14.
[0049] By adopting the above solution, by setting up a carrying rope 12 and an anti-slip sleeve 14, when the medicine in the shielded container 1 is used up, the shielded container 1 can be moved to a specific area for processing by carrying the carrying rope 12.
[0050] The working principle of this utility model:
[0051] In use, placing the drug storage container 2 inside the shielding container 1 ensures that the radioactive drugs contained therein will not cause harm to the human body during transport. During drug retrieval, first unscrew the shielding cover 3 from the threaded cylinder 101 on the shielding container 1. When the shielding cover 3 disengages from the threaded cylinder 101, the sealing plate 8 is lifted by the spring 10 and engages with the cylindrical portion 902 of the guide rod 9. Rotate the sealing plate 8 around the cylindrical portion 902 to one side, and use a needle to pierce the blind hole 7 of the rubber stopper 6. The drug can then be extracted from the drug storage container 2 through the needle. After extraction... Rotate the sealing plate 8 to a position coaxial with the rubber plug 6, and then tighten the shielding cover 3 and the threaded cylinder 101 through the threads. During the tightening process, the squeezing part 301 squeezes the sealing plate 8 downward, so that the sealing plate 8 engages with the square column part 901. At this time, the sealing plate 8 can stop rotating under the action of the square hole 802 and the square column part 901, so that the axis of the sealing plate 8 and the axis of the rubber plug 6 always coincide. Thus, after tightening, the conical part 801 and the flared part 701 are inserted to seal the punctured blind hole 7, preventing radioactive drugs from flowing into the shielding cover 3.
[0052] In summary, this portable and precise dispensing and injection protective device for radionuclide drugs, by incorporating a shielding container 1, a drug storage container 2, a threaded cylinder 101, a shielding cover 3, a bottle cap 4, a receiving cavity 5, a rubber stopper 6, a blind hole 7, a sealing plate 8, and a squeezing part 301, has the advantage of being able to seal the rubber stopper hole punctured by the needle after drug dispensing, thus solving the problem of easy leakage after drug dispensing in existing portable and precise dispensing and injection protective devices for radionuclide drugs.
