Description

Technical Field

[0001] This utility model relates to the field of inoculation device technology, specifically to a disposable inoculation device. Background Technology

[0002] Inoculation loops are a commonly used inoculation tool in bacterial culture, widely applied in many disciplines such as microbial detection, cell microbiology, and molecular biology. Existing disposable plastic inoculation loops are generally designed as a 180mm long thin rod with a ring-shaped or needle-like structure at the head, and are packaged for single use, making them convenient to use; however, the cost of using existing disposable inoculation loops is relatively high. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a disposable inoculation device with a reusable handle, which helps reduce usage costs.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A disposable vaccination device includes a placement frame, a handle, and two vaccination parts detachably connected to both ends of the handle. Each vaccination part has a connector fixed to its end, and the connector has a plug-in portion. Both ends of the handle have slots adapted to the plug-in portions. A locking structure is provided between the slots of the plug-in portions and the plug-in portions of the handle. The handle is equipped with a pressing structure that acts on the locking structure, so that the pressing structure controls the locking structure to unlock, thereby separating the vaccination parts from the handle. The placement frame has a stepped placement groove adapted to the connector.

[0006] Furthermore, the connector is fitted into the stepped placement groove and the end face of the connector is flush with the placement groove.

[0007] Furthermore, a receiving tray is placed at the bottom of the shelf.

[0008] Furthermore, one of the two inoculation parts includes a connecting rod and an annular inoculation head located at the end of the connecting rod, and the other inoculation part includes a connecting rod and a tip located at the end of the connecting rod.

[0009] Furthermore, multiple support blocks are installed on the handle.

[0010] Furthermore, the support block is fixedly connected to the handle portion, the support block is located on the periphery of the handle portion, and the end of the support block has a planar structure.

[0011] Furthermore, the snap-fit ​​structure includes an elastic snap-fit ​​arm fixed to the insertion part, and a slot is provided in the slot. The elastic snap-fit ​​arm snaps into the slot 5 to form a snap-fit ​​engagement, so that the handle part and the inoculation part are connected together.

[0012] Furthermore, the insertion part has a relief groove corresponding to the elastic snap-fit ​​arm. The pressing structure includes a pressing rod, which is slidably connected to the handle part. A spring is fixed between the pressing rod and the handle part. One end of the pressing rod extends into the snap-fit ​​groove. By operating the pressing rod, the elastic snap-fit ​​arm is pushed from the snap-fit ​​groove into the relief groove, thereby unlocking the snap-fit ​​structure.

[0013] The above technical solution has the following advantages or beneficial effects:

[0014] In the disposable inoculation device described in this utility model, during use, the connector can be placed in the stepped placement groove, thereby supporting the handle and the inoculation part. The connector can also be positioned through the stepped placement groove, making it convenient to disassemble the handle and reusable. Attached Figure Description

[0025] Please refer to the appendix. Figure 1 To be continued Figure 6 One embodiment of this utility model provides a disposable vaccination device, including a placement frame 14, a handle 1, and two vaccination parts 2 detachably connected to both ends of the handle 1. Each vaccination part 2 has a connector 7 fixed to its end, and the connector 7 has a plug-in portion 9. Both ends of the handle 1 have slots 8 adapted to the plug-in portions 9. A locking structure is provided between the slots 8 of the plug-in portions 9 and the plug-in portions 9 of the handle 1. The handle 1 is equipped with a pressing structure that acts on the locking structure, so that the pressing structure controls the locking structure to unlock, thereby separating the vaccination parts 2 from the handle 1. The placement frame 14 has a stepped placement groove 15 adapted to the connector 7. It is understood that, in use, the disposable vaccination device of this embodiment allows the connector 7 to be placed in the stepped placement groove 15, thereby supporting the handle 1 and the vaccination parts 2, and positioning the connector 7 through the stepped placement groove 15, thus facilitating the disassembly of the handle 1.

[0026] Please refer to the appendix. Figure 1 To be continued Figure 6 In one preferred embodiment, the connector 7 is fitted into the stepped placement groove 15 and the end face of the connector 7 is flush with the end face of the placement groove 15. In this embodiment, preferably, the groove wall of the stepped placement groove 15 is provided with friction texture, and the connector 7 is in contact with the groove wall of the stepped placement groove 15.
