Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a novel RFID-identified cryogenic carrier rod. Background Technology

[0002] Cryostats are medical devices used for the cryopreservation of biological samples and are widely used in assisted reproduction, cell therapy, and biological research. Their main function is to safely preserve oocytes, embryos, sperm, or other tissue samples in ultra-low temperature environments such as liquid nitrogen, preventing the samples from being damaged by ice crystal formation. They also integrate RFID technology to achieve non-contact identification and improve sample management efficiency. In simple terms, a cryogenic carrier typically consists of a carrier (including a handle and a slide rod) and a sheath; the carrier is used to fix the sample, while the sheath provides physical protection to prevent the sample from being contaminated or mechanically damaged during freezing or storage; some newer carriers also have built-in RFID tags for unique identification and tracking of the sample. However, some existing refrigeration carriers have a structural design problem where the RFID chip is tightly fixed to the carrier. This makes the disassembly process complicated and prone to damaging the carrier or the chip when the RFID module needs to be replaced or repaired. Furthermore, the RFID module is usually embedded inside the carrier, making it difficult for maintenance personnel to operate without damaging the overall structure. Therefore, a new type of RFID-identified refrigeration carrier is needed to solve the above problems. Utility Model Content

The abutment plate 23 abuts against the end face of the RFID collection block 14 at the end face away from the screw 24 and extends a predetermined distance along the side wall of the RFID collection block 14 at the end near the carrier rod 13. Connection structure 3 is installed between handle 11 and intermediate rod 12; In this embodiment, when the RFID collecting block 14 needs to be removed from the mounting cavity 121, the carrier plate 132 and the mounting plate 131 are first removed from one end of the carrier rod 13. Then, the operator rotates the screw 24, which drives the abutment plate 23, which is rotatably connected to the screw 24, to move along the axial direction of the screw 24 and away from the RFID collecting block 14. After the abutment plate 23 is completely detached from the RFID collecting block 14, the operator tilts the carrier rod 13 using the handle 11. Then, under the action of gravity, the RFID collecting block 14 slides along the inner wall of the carrier rod 13 and out from one end of the carrier rod 13. The operation is simple and will not cause damage to other parts of the main body 1, reducing the difficulty of operation and maintenance.

The sliding plate 25 is installed on one end of the abutment plate 23 near the RFID collection block 14, and the sliding plate 25 is slidably disposed in the sliding groove 221. In this embodiment, the sliding plate 25 slides along the slide groove 221. By setting the sliding plate 25, the abutment plate 23 is stably fixed to prevent the abutment plate 23 from shaking. Specifically, the plate carrier rod 13 has a pair of oppositely arranged snap-fit ​​blocks 133 and fixing blocks 134 at one end away from the intermediate rod 12.

In this embodiment, when the RFID collection block 14 needs to be removed from the mounting cavity 121, the operator first rotates the fixing stud 17 until it separates from the fixing post 16; then, the fixing post 16 is removed from the fixing block 134 and the carrier plate 132, and finally the carrier plate 132 and the mounting plate 131 are removed from one end of the carrier rod 13. At this time, the fixing block 134 and the snap-fit ​​block 133 are removed from the snap-fit ​​groove 135. Specifically, the connection structure 3 includes at least one pair of plug-in blocks 31 and plug-in pins 32. The plug-in block 31 has a plug-in hole 311. One of the plug-in blocks 31 in the pair is fixedly installed on the end face of the handle 11, and the other plug-in block 31 in the pair is fixedly installed on the end face of the intermediate rod 12. The pair of plug-in blocks 31 are engaged with each other, and the plug-in pin 32 is inserted into the plug-in hole 311. Specifically, the connection structure 3 also includes a pair of fixed frames 33, with adjacent sidewalls of the pair of fixed frames 33 fitting together, and at least one pair of plug-in posts 32 are provided, with one of the plug-in posts 32 in the pair being fixedly installed on the inner wall of one of the fixed frames 33 in the pair; Specifically, one of the plug-in pins 32 in the pair has a plug-in groove 321, and the other plug-in pin 32 in the pair has a plug-in rod 322. The connecting structure 3 also includes a rotating pin 34 and a torsion spring 35. The rotating pin 34 is rotatably disposed at one end of the plug-in rod 322, and the torsion spring 35 is connected to the rotating pin 34 and the plug-in rod 322. One of the fixed frames 33 has a limiting groove 331, and the rotating pin 34 has a limiting rod 341 at the end away from the plug-in rod 322. The rotating pin 34 is inserted into the limiting groove 331, and the limiting rod 341 is adapted to the limiting groove 331. In this embodiment, when it is necessary to remove the handle 11 from the end face of the intermediate rod 12, the operator rotates the rotating column 34 to align the limiting rod 341 with the limiting groove 331, at which point the torsion spring 35 deforms; then, the pair of fixing frames 33 are pulled in a direction away from each other, causing the plug-in rod 322 to gradually disengage from the plug-in groove 321 until the plug-in post 32 is completely disengaged from the plug-in hole 311; finally, the handle 11 and the intermediate rod 12 are pulled in a direction away from each other, which is simple to operate and reduces the difficulty of maintenance; Specifically, the handle 11 is 25-35mm long, 8mm wide, and 3mm thick, and the surface of the handle 11 is provided with an anti-slip treatment. The middle rod 12 is 40-60mm long, the carrier plate 132 is 15-25mm long, 0.5-3mm wide, and 0.1-0.5mm thick, and the outer sleeve 15 has an outer diameter of 10mm and a length of 70-100mm.

[0018] The working principle of this utility model is as follows: Before use, the operator uses an RFID reader to read the patient identity information and sample information in the RFID collection block 14 and checks and matches it with the information in the management system. During the freezing and thawing process, the operator uses an RFID reader to quickly and accurately identify the corresponding patient information, reducing the risk of mismatch that may occur during manual operation. When the RFID collection block 14 needs to be removed from the mounting cavity 121, the operator first rotates the fixing stud 17 until it separates from the fixing post 16; then, the fixing post 16 is removed from the fixing block 134 and the carrier plate 132, and finally the carrier plate 132 and the mounting plate 131 are removed from one end of the carrier rod 13. At this time, the fixing block 134 and the snap-fit ​​block 133 are removed from the snap-fit ​​groove 135. Then, the operator rotates the screw 24, which in turn drives the abutment plate 23, which is rotatably connected to the screw 24, to move along the axial direction of the screw 24 and toward a direction away from the RFID collection block 14; at this time, the sliding plate 25 slides along the slide groove 221. By setting the sliding plate 25, the abutment plate 23 is stably fixed to prevent the abutment plate 23 from shaking. After the contact plate 23 is completely detached from the RFID collection block 14, the operator tilts the carrier rod 13 using the handle 11; then, under the action of gravity, the RFID collection block 14 slides along the inner wall of the carrier rod 13 and out from one end of the carrier rod 13; the operation is simple and will not cause damage to other parts of the main body 1, reducing the difficulty of operation and maintenance. Furthermore, when it is necessary to remove the handle 11 from the end face of the intermediate rod 12, the operator rotates the rotating column 34 to align the limiting rod 341 with the limiting groove 331, at which point the torsion spring 35 deforms; then, the pair of fixed frames 33 are pulled in a direction away from each other, causing the plug rod 322 to gradually disengage from the plug groove 321 until the plug post 32 is completely disengaged from the plug hole 311; finally, the handle 11 and the intermediate rod 12 are pulled in a direction away from each other, which is simple to operate and reduces the difficulty of maintenance.
