The container in the disclosure can be used for a transferring and transporting stage of a medicine bottle containing radioactive medicine, and can also be used for a treatment stage of accessing the medicine bottle into an injection system, wherein the inner side wall of the containing groove in the container body and the outer side wall of the protruding part of the cover body are provided with specific shapes matched with each other, so that when the cover body is buckled on the container body, the first axis of the container body is basically collinear with the second axis of the cover body, and further the syringe assembly can be basically aligned with the medicine bottle containing radioactive medicine in the containing groove after being inserted into the through hole in the cover body, and therefore the medicine bottle is accessed into the injection system under the condition that the medicine bottle containing radioactive medicine is positioned in the radiation-proof container, the contact between medical staff and the radioactive medicine is reduced, and radiation protection is provided for the medical staff.

Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.

Fig. 1 is a schematic structural view of a container according to some embodiments of the present disclosure, and fig. 2 is a schematic explosive structural view of a container according to some embodiments of the present disclosure, in which a cover body is separated from a container body. As shown in fig. 1 and 2, the container 100 includes a container body 10 and a lid 20, and when the lid 20 is engaged with the container body 10, a relatively airtight space is formed inside the container 100. In some embodiments, the body 10 and the cover 20 may be made of a radiation-proof material, and may be one or a combination of lead, lead alloy, or tungsten alloy, such as lead. Thus, the container 100 may be used to house a vial containing a radiopharmaceutical, such as a penicillin vial. The container 100 may be used as a carrier for movement or transport of the vial of radiopharmaceutical to prevent radiation leakage during movement or transport and to prevent environmental contamination.

As shown in fig. 1 and 2, an open accommodating groove 13 is provided in the container body 10, and the accommodating groove 13 includes a first accommodating space 131, a second accommodating space 132 and a third accommodating space 133 sequentially adjacent to the bottom of the accommodating groove, wherein the third accommodating space 133 is configured to accommodate at least a portion of a medicine bottle containing a radiopharmaceutical.

The first sidewall 1311 of the first accommodating space 131 extends along a first direction, such as a vertical direction Y, the first direction is parallel to the first axis m1 of the container body 10, the second sidewall 1321 of the second accommodating space 132 gradually tapers from an end of the first sidewall 1311 near the second accommodating space 132 toward the first axis m1 of the container body 10 in the first direction, and the third sidewall 1331 of the third accommodating space 133 extends from an end of the second sidewall 1321 far from the first accommodating space 131 along the first direction. In some embodiments, the size of the third receiving space is substantially slightly larger than the size of the vial, such that the vial is prevented from substantially shaking in a horizontal direction during transportation when placed in the third receiving space.

The cover 20 includes a cover body 22 and a protruding portion 21 extending from a bottom surface of the cover body 22 in a direction away from a top surface of the cover body, and the protruding portion 21 includes a first protruding portion 211 and a second protruding portion 212 sequentially away from the top surface of the cover body. The first outer sidewall 2111 of the first protruding portion 211 extends along a second direction, such as a vertical direction Y, which is parallel to the second axis m2 of the cover 20, and the second outer sidewall 2121 of the second protruding portion 212 gradually tapers from an end portion of the first outer sidewall 2111 near the second protruding portion 212 toward the second axis m2 of the cover 20 in the second direction.

When the cover 20 is fastened to the container body 10, the first protruding portion 211 and the second protruding portion 212 are respectively received in the first receiving space 131 and the second receiving space 132, the first outer sidewall 1311 is matched and attached to the first sidewall 2111, and the second sidewall 1321 is matched and attached to at least a portion of the second outer sidewall 2121, so that the first axis m1 is substantially collinear with the second axis m 2.

Fig. 3 is a schematic view of a container access injection system containing a vial containing a radiopharmaceutical in accordance with some embodiments of the disclosure, and fig. 4 is a schematic cross-sectional view of fig. 3. As shown in connection with fig. 1 to 4, the medicine bottle 300 containing the radiopharmaceutical is accommodated in the accommodation groove 13 of the container body 10, specifically, a cylindrical body below the neck of the medicine bottle 300 is accommodated in the third accommodation space 133. The push pin assembly 200 in the injection system can be threaded into the vial 300 through the through hole of the cap 20 so that, with the vial 300 containing the radiopharmaceutical in the radiation-protected container 100, access to the injection system with the vial 300 reduces contact of the healthcare worker with the radiopharmaceutical, providing radiation protection to the healthcare worker, but such operation requires a relatively precise alignment of the push pin assembly 200 with the vial 300 in the container 100.

In the present disclosure, the inner side wall of the accommodating groove in the container body and the outer side wall of the protruding portion of the cover body have specific shapes that are matched with each other, so that when the cover body is buckled on the container body, the first axis of the container body is substantially collinear with the second axis of the cover body, so that the cover body and the container body are aligned and buckled, and a large deviation exists in the horizontal direction when the cover body and the container body are buckled. So can make when the medicine bottle that will be equipped with the radiopharmaceutical inserts injection system later, push pin subassembly inserts the through-hole on the lid after can be basically with the medicine bottle of holding the radiopharmaceutical in the holding groove alignment to realize under the medicine bottle that holds the radiopharmaceutical is located the circumstances of radiation protection in the container, will the medicine bottle inserts injection system, reduced medical personnel and the contact of radiopharmaceutical, for medical personnel's supply radiation protection.

Fig. 5 is an exploded structural view of a container body provided in some embodiments of the present disclosure. As shown in connection with fig. 1-5, the container body 10 includes an outer body 11 and an inner body 12. The outer body is internally provided with an open first accommodating groove 111, the inner body 12 is detachably accommodated in the first accommodating groove 111, and the inner body 12 is internally provided with a second accommodating groove 121 with an opening. When the inner body 12 is mounted in the first accommodating groove 111 of the outer body 11, the second accommodating groove 121 includes the second accommodating space 132 and the third accommodating space 133, and in the first accommodating groove 111, a space from the top of the inner body 12 to the top of the outer body 11 constitutes the first accommodating space 131.

Since the inner body 12 and the outer body 11 are detachable, different inner bodies 12 can be mounted in the same outer body, and different inner bodies 12 can have different second receiving grooves for receiving different sizes of medicine bottles 300. When the container 100 is used to house different size vials 300, only the inner body 12 is replaced differently, and the container 100 is not replaced as a whole, thereby reducing the cost.

For example, the inner body includes multiple types of inner bodies, including, for example, a first inner body and a second inner body of different types FIG. 6 is a schematic structural view of the different inner bodies provided in some embodiments of the present disclosure. Fig. 6 (a) is a schematic structural view of the first inner body 12', and (B) is a schematic structural view of the second inner body 12 ". As shown in fig. 5 to 6, the first inner body 12' has the same outer diameter and the same height as the second inner body 12", and the inclination of the side wall of the second accommodating space 132' corresponding to the first inner body 12' is the same as the inclination of the side wall of the second accommodating space 132" corresponding to the second inner body 12 ". Thus, both can be mounted into the first receiving groove 111 in the outer body 11, and the cover 20 can be matingly snapped onto the container body 10.

The height of the second accommodating space 132 'corresponding to the first inner body 12' is different from the height of the second accommodating space 132 "corresponding to the second inner body 12", for example, the height of the second accommodating space 132 'corresponding to the first inner body 12' is greater than the height of the second accommodating space 132 "corresponding to the second inner body 12". The outer diameter of the third accommodating space 133 'corresponding to the first inner body 12' is also different from the outer diameter of the third accommodating space 133 "corresponding to the second inner body 12", for example, the outer diameter of the third accommodating space 133 'corresponding to the first inner body 12' is smaller than the outer diameter of the third accommodating space 133 "corresponding to the second inner body 12". The second inner body 12 "may house a vial having a larger outer diameter than the first inner body 12'.

In some embodiments, the material of the outer body is a high density metal material, which may be at least one or a combination of lead, lead alloy or tungsten alloy, such as lead, and the material of the inner body may be at least one or a combination of lead, lead alloy, tungsten alloy or organic polymer material, such as plexiglas, which produces high energy beta decay when the radiopharmaceutical, such as radioactive glass microspheres, impinges on elements with high atomic numbers, which release very strong bremsstrahlung. The protection against beta rays is first achieved with low Z materials. Therefore, the inner body material is selected as the organic glass with low Z material, which is favorable for reducing the bremsstrahlung radiation of the radioactive glass microspheres.

In some embodiments, referring to fig. 1-4, the cap 20 has a through hole 23 extending through the cap 20, the through hole 23 configured to insert a push pin assembly 200, and the container further includes a plug (not shown) mated to the through hole, the plug configured to be inserted into the through hole 23. The axis of the through hole 23 coincides with the second axis m2 of the cover 20, and penetrates the boss 21 of the cover 20. When the container 100 stores the vial 300 containing the radiopharmaceutical, the cap 20 is engaged with the container body, and the stopper is inserted into the through hole 23 of the cap 20 to block the through hole 23, thereby realizing the airtight and isolated storage of the vial 300 containing the radiopharmaceutical. In some embodiments, the cover and plug may each be made of a radiation resistant material, such as lead, to avoid radiation leakage. When the radiopharmaceutical in the radiopharmaceutical vial 300 is to be injected into the patient for treatment, the medical staff can pull the stopper out of the cap 20, insert the push-pin assembly 200 in the injection system into the through hole 23 of the cap 20, and insert the liquid guide needle of the push-pin assembly 200 into the vial 300 located in the third accommodating space 133 of the container 100 from the cap of the vial, so that the vial with the radiopharmaceutical is connected into the injection system under the condition that the vial with the radiopharmaceutical is located in the radiation-proof container, thereby reducing the contact between the medical staff and the radiopharmaceutical and providing radiation protection for the medical staff.

In some embodiments, as shown in fig. 1-4, in a cross section through the first axis m1, the second sidewall 1321 of the second accommodating space 132 forms an angle α with the first axis of 20 ° to 30 °. In placing the vial with radiopharmaceutical into the container body 10, the vial 300 may be placed directly into the third receiving space 133 of the container body 100 while the axis of the vial 300 is preferably aligned with the first axis m1 of the container body 10. When the axis of the medicine bottle 300 deviates greatly from the first axis m1 of the container body 10, the bottom of the medicine bottle 300 may first contact the second sidewall 1321 of the second accommodating space 132, and since the included angle α between the second sidewall 1321 and the first axis is 20 ° to 30 °, the medicine bottle 300 may slide into the third accommodating space 133 under the guidance of the second sidewall 1321.

In some embodiments, as shown in fig. 1-4, the side wall of the cover body 22 of the cover body 20 is provided with a groove 221, for example, a continuous annular groove, and the groove 221 may also be a discontinuous annular groove provided on the periphery of the side wall of the cover body 22. The loading of the radiopharmaceutical vial with the radiopharmaceutical into the container 100 of the present disclosure may be accomplished by using a robot arm, for example, the cap 20 may be first separated from the container body 10 by using the robot arm, at which time the robot arm may be inserted into the recess 221 to remove the cap 20 from the container body 10, then the robot arm may pick up the radiopharmaceutical vial 300 with the radiopharmaceutical into the third receiving portion 133 of the container body 10, and then the cap 20 may be fastened to the container body 10 by using the robot arm, and the entire process may be automatically accomplished by using the robot arm without manual operations, for example, in a closed space with radiation protection, thereby avoiding injury to the human body by radiation.

In some embodiments, as shown in fig. 1-4, the container 100 is, for example, substantially cylindrical, as are the container body 10 and the lid body 22 of the lid 20. The first accommodating space 131 is cylindrical, the second accommodating space 132 is inverted truncated cone-shaped, and the third accommodating space 133 is cylindrical. The shape of the third receiving space 133 substantially matches the shape of the vial 300 of radiopharmaceutical. In some embodiments, as shown in fig. 4, when the vial 300 of the radiopharmaceutical is loaded into the third accommodation space 133 in the container body 10, a portion below the neck of the vial 300 is accommodated in the third accommodation space 133, and a portion above the neck is accommodated in the second accommodation space 132, due to a specific structure of the accommodation groove 13 in the container body 10, i.e., a specific combination of the first accommodation space 131, the second accommodation space 132, and the third accommodation space 133, it is convenient for the robot arm to clamp the neck of the vial 300 to put the vial 300 into the container body 10 or to remove the vial 300 from the container body 10.

In some embodiments, when the cap 20 is snapped onto the container body 10, the second protrusion 212 is spaced from the vial 300 by a distance less than a predetermined distance, such as 50mm, in the first axial direction m 1. To avoid a large amount of shaking of the vial 300 accommodated in the container 100 in the vertical direction. In some embodiments, when the cap 20 is snapped onto the container body 10, the second protrusion 212 abuts the vial 300.

In some embodiments, when the inner body 12 is installed in the outer body 11, the inner body 12 and the outer body 11 are in interference fit, so that the inner body 12 is prevented from shaking in the first accommodating groove 111 in the outer body 11, and the medicine bottle 300 is ensured to be stably placed in the container body 100.

Fig. 7 is an exploded view of a container according to other embodiments of the present disclosure, in which a container body is separated from a cap body, a rubber pad portion of a boss of the cap body is separated from other portions of the cap body, and a medicine bottle 300 accommodated in the container is shown in fig. 7. If the rubber pad is mounted at the end of the protruding portion, the overall structure of the cover is similar to that of the cover shown in fig. 2, and the same points are not described here again.

As shown in fig. 1 and 7, the container 100 includes a container body 10 and a lid 20, and when the lid 20 is engaged with the container body 10, a relatively airtight space is formed inside the container 100. In some embodiments, the container body 10 and the cap 20 may each be made of a radiation resistant material, such as lead, and the like, whereby the container 100 may be used to house a vial containing a radiopharmaceutical, such as a penicillin bottle. The container 100 may be used as a carrier for movement or transport of the vial of radiopharmaceutical to prevent radiation leakage during movement or transport and to prevent environmental contamination.

As shown in fig. 1 and 7, an open receiving slot 13 is provided in the container body 10, the receiving slot 13 being configured to receive at least a portion of a vial 300 containing a radiopharmaceutical. The accommodating groove comprises, for example, the aforementioned first accommodating space 131, the second accommodating space 132 and the third accommodating space 133 which are sequentially adjacent to the bottom of the accommodating groove, wherein the third accommodating space 133 is configured to accommodate at least a portion of a medicine bottle containing a radiopharmaceutical. The cover 20 includes a cover body 22 and a boss 21 extending from a bottom surface of the cover body 22 in a direction away from a top surface of the cover body 22. The end of the protruding portion 21 away from the cover body 22 is provided with a rubber pad 2123.

Fig. 8 is a schematic perspective view of a rubber pad provided in some embodiments of the present disclosure, and fig. 9 is a cross-sectional view of a rubber pad provided in some embodiments of the present disclosure. As shown in fig. 1 and 7-9, the end of the rubber pad 2123 away from the cover body is provided with a first groove 21231, and the side wall of the first groove 21231 gradually moves away from the axis of the cover body, namely, the second axis m2 along with moving away from the cover body. When the cap 20 is fastened to the container body 10, the first groove 21231 accommodates the top of the vial 300, so that the second axis m2 of the cap 20 is collinear with the axis of the vial 300, hereinafter referred to as the third axis.

In this case, when the container 100 is used to hold the container 300 of the radiopharmaceutical vial, and the cover 20 is aligned and fastened to the container body 10, the top surface of the vial is restrained in the first groove 21231, so that it can be stably placed in the container, and the push pin assembly can be substantially aligned with the vial containing the radiopharmaceutical in the holding groove after being inserted into the through hole in the cover, so that the vial is connected to the injection system with the vial containing the radiopharmaceutical in the radiation-proof container, thereby reducing contact between medical staff and the radiopharmaceutical and providing radiation protection to the medical staff.

Specifically, referring to fig. 1,7-9, the size of the third receiving space 133 in the receiving groove 13 in the container body 10 in the second direction, for example, the horizontal direction X, will generally be slightly larger than the size of the vial 300 in the horizontal direction, for example, the inner diameter of the third receiving space 133 is slightly larger than the diameter of the vial 300. This arrangement allows the vial 300 to be conveniently placed into the third receiving space 133 by a robot, allowing the robot holding the vial 300 to have a certain deviation in alignment of the third receiving space 133.
