Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a protective lead can for a syringe. Background Art

[0002] With the widespread application and promotion of nuclear technology, radiation diagnosis and treatment technology, etc. in medicine, the rapid development of medical science, especially clinical medicine, has been promoted, bringing great benefits to patients. However, in clinical medical diagnosis and treatment, the oral, injection and application treatment methods for radioactive drugs will cause radiation to patients and staff, especially staff, who are exposed to radioactive drugs for a long time and in large doses during packaging or drug injection, and will be exposed to large doses of external radiation. Therefore, the issue of radiation shielding protection in clinical medicine is particularly important, and the protection requirements are also very strict. The syringe must be shielded to ensure the safety of the staff and the surrounding people, protect the environment and avoid radioactive contamination.

[0003] At present, the most common method used in clinical diagnosis is still the direct injection method using a syringe. Although it is easy to use, it is extremely unsafe for shielding the radioactive elements in the drug. In the transportation process of radioactive drugs, lead cans are often used as radiation protectors. After the syringe is used to extract the drug solution, the syringe is placed in the transport lead can, and then the syringe with the extracted drug solution is transported to the injection window with radiation protection function through the transport lead can. After that, the syringe is taken out of the lead can in the injection window and the injection is carried out.

[0004] An existing lead can for transporting syringes is as follows Figure 1 As shown, it comprises a tank body 1 and a tank cover 2, wherein the tank body 1 is a hollow columnar structure with an open upper end and a sealed lower end, a carrying plate 3 is arranged at the upper opening of the tank body 1, a groove 31 for placing a positioning block at the rear end of the syringe barrel of the syringe is arranged on the carrying plate 3, and a through hole 32 for extending into the syringe barrel of the syringe is arranged in the middle of the groove 31; the tank cover 2 is in the shape of a truncated cone with a sealed upper end and an open lower end, after the syringe draws the liquid medicine, the syringe barrel of the syringe is placed in the tank body 1, and then the tank cover 2 is covered, and the piston rod extending out of the syringe barrel and the push rod handle on the piston rod are located in the tank cover 2.

[0005] The length of the lead tank is fixed. If the syringe used has a longer barrel and more liquid medicine is drawn, the overall length of the syringe may exceed the length of the lead tank after the liquid medicine is drawn. After the syringe is placed and the tank cover is closed, the liquid medicine in the syringe will be pressed down by the sealed end of the tank cover, causing the liquid medicine in the syringe to be squeezed out. If the lead tank is made the longest, although it can be used for more types of syringes, there is a problem of increased space when not in use.

[0006] In view of this, the utility model improves the existing lead can and provides a protective lead can for a syringe with adjustable length. Utility Model Content

Without departing from the design spirit of the utility model, various modifications and improvements made to the technical solution of the utility model by ordinary technicians in this field should fall within the protection scope of the utility model.

[0022] like Figures 2 to 6 As shown, the protective lead can for syringes of this embodiment includes a can body 1 and a can cover 2.

[0023] The tank body 1 is a hollow columnar structure with an upper opening and a lower sealing, and the tank body 1 adopts a telescopic structure. Specifically in this embodiment, the tank body 1 includes an upper tank body 11 and a lower tank body 12, the upper tank body 11 is arranged at the upper end of the lower tank body 12, the upper tank body 11 is a hollow columnar structure with both ends open, the lower tank body 12 is a hollow columnar structure with a lower sealing and an upper opening, the lower end inner wall of the upper tank body 11 is connected with the upper end outer wall of the lower tank body 12 by a thread, the length of the tank body 1 can be changed by rotating the lower tank body 12 or the upper tank body 11, and the thread on the side wall of the lower tank body 12 is continuously screwed out of the upper tank body 11, so that the length of the tank body 1 can be increased; the lower tank body 12 can be rotated in the opposite direction, and the thread on the side wall of the lower tank body 12 is continuously screwed into the upper tank body 11, so that the length of the tank body 1 can be shortened.

[0024] The can cover 2 is a hollow columnar structure with a sealed upper end and an open lower end, and it is a telescopic structure. Specifically in this embodiment, the can cover 2 includes an upper cover 21 and a lower cover 22, the upper cover 21 is arranged at the upper end of the lower cover 22, the upper cover 21 is a hollow columnar structure with a sealed upper end and an open lower end, and the lower cover 22 is a hollow columnar structure with two ends open, the outer surface of the lower end of the upper cover 21 is threadedly connected with the inner surface of the upper end of the lower cover 22, and the length of the can cover 2 can be changed by rotating the upper cover 21 or the lower cover 22, and the length of the can cover 2 can be increased by continuously screwing the threads on the outer surface of the upper cover 21 out of the lower cover 22; the length of the can cover 2 can be shortened by rotating the upper cover 21 in the opposite direction and continuously screwing the threads on the outer surface of the upper cover 21 into the lower cover 22.

[0025] The upper end of the tank body 1 is detachably connected to the lower end of the tank cover 2. Specifically, the upper end of the upper tank body 11 is connected to the lower end of the lower cover 22 via threads.

[0026] A bearing plate 3 is provided at the upper opening of the upper tank body 11. A groove 31 for placing a positioning block at the rear end of the syringe barrel is provided on the bearing plate 3. A through hole 32 for inserting the syringe barrel is provided in the middle of the groove 31. When the syringe barrel is thin, the area of ​​the positioning block at the rear end of the syringe barrel is small and is set smaller than the area of ​​the through hole 32. At this time, the positioning block cannot be placed on the groove 31 of the bearing plate 3. To address this problem, two receiving grooves 33 are relatively provided on the side wall of the through hole 32 of the bearing plate 3 of this embodiment. An adjusting plate 4 is provided in each of the two receiving grooves 33. The cross section of the adjusting plate 4 is half-moon-shaped.

The push blocks 41 of the two adjustment plates 4 move along the linear groove 34, thereby changing the size of the through hole 32. When the two adjustment plates 4 move out of the receiving groove 33, the gap between the adjustment plates 4 is used to extend the syringe barrel, and the plate surface of the adjustment plate 4 extending out of the receiving groove 33 can be used to place the positioning block at the rear end of the syringe barrel.

[0027] The side wall of the can body 1 of this embodiment is provided with a handle 5 for easy gripping. The upper end of the can cover 2 is provided with a rotating rod 6, which is specifically provided at the upper end of the upper cover 21, so that the upper cover 21 can be easily rotated. The lower cover 22 can be provided with anti-slip grooves for easy rotation of the lower cover 22.

[0028] In summary, the tank body 1 and the tank cover 2 of the utility model are both retractable structures, so the height of the tank body 1 and the tank cover 2 can be changed, so as to be suitable for syringes of different lengths. When not in use, the tank body 1 and the tank cover 2 can be shortened to the shortest, which can reduce the occupied space. Moreover, the length of the through hole 32 can be adjusted by the adjustment plate 4, so as to be suitable for syringes of different thicknesses.
