AI Technical Summary
Existing lead shielding devices, which use lead plates, are prone to damage, resulting in poor shielding effectiveness and failing to provide long-term and effective protection for medical staff and patients from radiation from radiopharmaceuticals.
The storage tank design, which is filled with lead powder, uses a structure formed by a door-shaped frame and side plates, combined with components such as rectangular tubes and stop pins, to achieve stable filling of lead powder and provide an observation channel, thus avoiding damage to the lead plate.
This design achieves good stability of lead powder, making it less prone to damage and providing a long-lasting shielding effect. It ensures radiation isolation during the transmission of radiopharmaceuticals and facilitates observation and prevents the device from tipping over.

Abstract
Description
Technical Field
[0001] This utility model relates to a shielding device, and more specifically, a lead shielding device for the transmission of radiopharmaceuticals. Background Technology
[0002] Lead shielding is crucial during the transport of radiopharmaceuticals to ensure effective radiation protection for medical personnel and patients when using or handling these drugs. These drugs are commonly used in diagnostic and therapeutic procedures, such as radionuclide therapy and imaging examinations. Lead shielding reduces the radiation exposure risk to medical personnel, especially during preparation, transport, and injection. However, existing lead shielding devices often use lead plates, and their effectiveness diminishes when these plates are damaged. Summary of the Invention
[0003] To overcome the shortcomings of the prior art, this utility model provides a lead shielding device for radiopharmaceutical transmission. Its advantages are that this utility model can easily fill lead powder to shield radiopharmaceuticals, will not cause damage to the lead plate, and has good stability.
[0004] A lead shielding device for radiopharmaceutical delivery includes a gate-shaped frame, characterized in that: side plates are connected to the front and rear sides of the gate-shaped frame by screws, and a storage groove is formed between the gate-shaped frame and the two side plates, the storage groove being filled with lead powder.
[0005] A top cover is inserted into the upper side of the storage slot.
[0006] The side plate is provided with square holes corresponding to the rectangular tubes, and the rectangular tubes pass through the two square holes.
[0007] Both ends of the rectangular tube are fitted with retaining pins.
[0008] Glass is bonded to the middle of the inner side of the rectangular tube.
[0009] Each of the side panels has a right-angle plate fixed to its lower end.
[0010] A connector is fixed to the lower side of one end of the rectangular tube.
[0011] A grooved rod is fixed on the connector.
[0012] The grooved rod is provided with a strip groove.
[0013] The lead plate can be inserted into the slot. Attached Figure Description

[0019] like Figure 1-3 As shown, this example allows for easy replacement without the risk of damage like that seen with rubber sheets.
[0020] The radiopharmaceutical delivery lead shielding device includes a gate-shaped frame 1, with side plates 3 connected to the front and rear sides of the gate-shaped frame 1 by screws. A storage tank 9 is formed between the gate-shaped frame 1 and the two side plates 3. The storage tank 9 is filled with lead powder. Since the lead powder is powder, it can be easily replaced and will not be damaged like rubber lead plates, thus exhibiting good stability.
[0021] like Figure 1-3 As shown, this example allows for the convenient sealing of the top of storage slot 9.
[0022] Since a top cover 8 is inserted on the upper side of the storage slot 9, the top cover 8 can easily close the upper side of the storage slot 9.
[0023] like Figure 1-3 As shown, this example can achieve the effect of forming an observation channel through the rectangular tube 7.
[0024] Since the side plate 3 is provided with square holes corresponding to the rectangular tube 7, the rectangular tube 7 passes through two square holes, thus forming an observation channel, which makes it convenient to observe the radiopharmaceutical behind the side plate 3.
[0025] like Figure 1-3 As shown, this example can achieve the effect of preventing the rectangular tube 7 from detaching from the two side plates 3.
[0026] Because both ends of the rectangular tube 7 are fitted with retaining pins 2, the retaining pins 2 prevent the rectangular tube 7 from detaching from the two side plates 3.
[0027] like Figure 1-3 As shown, this example allows for convenient observation of the radiopharmaceutical on the rear side of side plate 3.
[0028] Because glass 11 is bonded to the middle of the inner side of the rectangular tube 7, the radiopharmaceutical situation on the rear side of the side plate 3 can be easily observed through the glass 11.
[0029] like Figure 1-3 As shown, this example can achieve the effect of preventing the shielding device from tipping over.
[0030] Since each of the side plates 3 is welded to a right-angle plate 4 at its lower end, the right-angle plate 4 prevents the shielding device from tipping over.
[0031] like Figure 1-3 As shown, this example can achieve the effect of preventing radioactive materials from passing through the rectangular tube 7.
[0032] Because a connector 10 is welded to the lower side of one end of the rectangular tube 7, and a grooved rod 5 is welded on the connector 10, and a strip groove is provided on the grooved rod 5, the lead plate 6 can be inserted into the strip groove, so that the rectangular tube 7 can be shielded when needed to prevent radioactive materials from passing through the rectangular tube 7, and the lead plate 6 can be removed when observing.
