Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a powerful sample gripping inoculation ring. Background Technology

[0002] An inoculating loop is a widely used laboratory instrument in microbial detection, cell biology, and molecular biology. The inoculating loop consists of a handle, a ring rod, and a ring or wire for streaking. Currently, laboratory inoculating loops can be classified by material into reusable metal inoculating loops and disposable plastic inoculating loops.

[0003] Currently, most widely used inoculation loops are made of copper alloy steel or aluminum alloy rods with a nickel-chromium wire or platinum wire installed at the front end. The front end of the wire is folded into a loop. Because the surface of existing inoculation loops is relatively smooth, it is not easy to pick up the desired location when sampling sputum, feces, pus, etc. (for example, sputum is slippery, and pus should be sampled from areas with pus). This may result in the inoculation loop not picking up the required sample or picking up an insufficient amount of sample, leading to poor sampling results. Furthermore, existing inoculation loops require frequent cleaning and disinfection when sampling different samples, which is cumbersome and can easily affect sampling efficiency. Utility Model Content

[0004] To address the problems mentioned above, this invention provides a powerful sample-grabbing inoculation loop, which facilitates the collection of the required sample, provides better sampling results, is easy to disassemble and replace, and has higher sampling efficiency.

[0005] This utility model is implemented as follows: a powerful sample gripping inoculation loop includes a rod body, one end of which is fixedly connected to a connector, the outer wall of which is provided with an external thread, and the outer wall of which is threadedly connected to a threaded cylinder through the external thread, the other end of which is fixedly connected to a fixing rod, the other end of which is embedded and fixedly connected to a ring rod, and the other end of which is fixedly connected to the inoculation loop body.

[0006] The outer wall of the inoculation ring body is provided with multiple storage slots, and multiple arrayed dipping columns are fixedly connected to the outer wall of the inoculation ring body. The outer wall of the inoculation ring body is provided with multiple arrayed dipping mechanisms located between two adjacent dipping columns. The dipping mechanism includes two first dipping plates and two second dipping plates fixedly connected to the outer wall of the inoculation ring body and located between two adjacent storage slots.

[0007] For ease of gripping, the preferred embodiment of the powerful sample-grabbing inoculation ring of this invention has a handle fixedly connected to the other end of the rod, and an anti-slip sleeve fixedly connected to the outer wall of the handle.

[0008] To increase the surface area of ​​the inoculation ring, as a preferred embodiment of the powerful sample-grabbing inoculation ring of this invention, the outer walls of the plurality of dipping columns are provided with threaded grooves, and the outer walls of the two first dipping plates and the two second dipping plates are fixedly connected with arc-shaped blocks.

[0009] To facilitate the sterilization of the inoculation loop, the threaded cylinder, fixing rod, ring rod, inoculation loop body, dipping column, first dipping plate, second dipping plate and arc block of this utility model are preferably made of nickel-chromium alloy.

[0010] To make the rod and handle lighter, the rod and handle of the powerful sample gripping inoculation ring of this utility model are preferably made of polystyrene plastic.

[0011] To facilitate sample collection, the ring rod of the present invention, preferably a powerful sample-grabbing inoculation ring, is configured as an L-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features multiple storage slots on the outer wall of the inoculation loop body, increasing the surface area of ​​the inoculation loop body. Multiple arrayed dipping columns are fixedly connected to the outer wall of the inoculation loop body. At the same time, the contact surface with the sample is increased by the threaded groove and the arc-shaped block, which can pick up more sample. By setting a first dipping plate and two second dipping plates, the sample picked up is less likely to be lost from the inoculation loop body, making it easier to pick up the required sample and improving the sampling effect.

[0014] By rotating the threaded cylinder, the cylinder is disengaged from the outer wall of the connector, and the ring rod and inoculation loop body are removed. The new ring rod and inoculation loop body are then screwed onto the outer wall of the connector through the threaded cylinder. No cleaning is required before sterilization and use, which facilitates the disassembly and replacement of the inoculation loop and improves sampling efficiency. Attached Figure Description

By setting a first dipping plate 13 and two second dipping plates 14, the sample is less likely to be lost from the inoculation ring body 9, making it easier to pick up the required sample and improving the sampling effect.

[0024] When the inoculation loop body 9 has taken a sample from one sample, and another sample needs to be taken, the threaded cylinder 6 is rotated to disengage from the outer wall of the connector 4. At the same time, the ring rod 8 and the inoculation loop body 9 are removed and replaced with new ring rod 8 and inoculation loop body 9. No cleaning is required and they can be directly disinfected and used. This makes it easy to disassemble and replace the inoculation loop, and the sampling efficiency is higher.

[0036] When the inoculation loop body 9 has taken a sample from one sample, and another sample needs to be taken, the threaded cylinder 6 is rotated to disengage from the outer wall of the connector 4. At the same time, the ring rod 8 and the inoculation loop body 9 are removed.
