Detailed Implementation
[0020] This application provides a disposable inoculation loop ejection device, which has a simple structure, is easy to manufacture, requires no hands to operate, is reusable, and avoids contamination.
[0021] The structure of the exemplary disposable inoculation loop ejection device provided in this application can be referred to... Figure 1 and Figure 2 .like Figure 1 As shown, the disposable inoculation loop ejection device includes: a housing 1, an inoculation loop container 2, a spring-loaded assembly 3, and a central rod 4. The top surface of the housing 1 has a spring-loaded hole 11 corresponding to the position of the inoculation loop container 2; preferably, the housing 1 is cylindrical or elliptical. The inoculation loop container 2 is symmetrically arranged inside the housing 1, with its bottom surface inclined downwards towards the circumference of the housing 1, such that the lowest point of the inoculation loop container 2 is directly below the spring-loaded hole 11; the inoculation loop container 2 is configured to accommodate multiple disposable inoculation loops; preferably, the disposable inoculation loop ejection device includes an even number of symmetrically arranged inoculation loop containers 2, such as 2, 4, or 6, etc. Figure 1 The diagram shows a structure comprising two inoculation loop containers 2. The bouncing assembly 3 includes a bouncing button 31, a metal rod 32, an inoculation loop clamp 33, and a spring 34. The bouncing button 31 is located on the top surface of the housing 1. The upper end of the metal rod 32 is connected to the bouncing button 31, and the lower end of the metal rod 32 is connected to the inoculation loop clamp 33. The inoculation loop clamp 33 passes through an opening on the side of the inoculation loop container 2, and the end of the inoculation loop clamp 33 located inside the inoculation loop container 2 has a gripping structure (e.g., fork-shaped or V-shaped), while the end of the inoculation loop clamp 33 located outside the inoculation loop container 2 is movably connected to a central rod 4. One end of the spring 34 is connected to the outside of the inoculation loop container 2, and the other end of the spring 34 is connected to the inoculation loop clamp 33. The central rod 4 is located at the center of the bottom of the housing 1. The disposable inoculation loop ejection device is configured such that when the pop-up button 31 is pressed, the inoculation loop clamp 33 moves downward; when the pop-up button 31 is released, the spring drives the inoculation loop clamp 33 to reset, and at the same time, the gripping structure of the inoculation loop clamp 33 holds the disposable inoculation loop in the inoculation loop container 2 and makes it pass through the pop-up hole 11 and eject.
[0022] In a preferred embodiment of this application, the inoculation loop clamp 33 has a U-shaped groove at its end located outside the inoculation loop container 2, and the inoculation loop clamp 33 is movably connected to the central rod 4 through the U-shaped groove; the central rod 4 is provided with a limiting rod 41 and a limiting inclined surface 42. (Reference) Figure 2 , Figure 2 The enlarged view provided shows the detailed structure of center rod 4. (See attached image.) Figure 2 As shown, the limiting rod 41 is configured to embed into the U-shaped groove of the inoculation loop clamp 33; the limiting ramp 42 is configured to limit the lowest position reached by the inoculation loop clamp 33. The disposable inoculation loop ejection device is further configured such that when the ejection button 31 is pressed, the inoculation loop clamp 33 slides downward along the U-shaped groove towards the center of the housing 1 until it reaches the lowest position defined by the limiting ramp 42 (e.g., at this time, the inoculation loop clamp 33 is in the position shown in the image). Figure 1 (as shown on the left side); when the pop-up button 31 is released, the spring 34 drives the inoculation loop clamp 33 to reset, and at the same time, the gripping structure of the inoculation loop clamp 33 holds the disposable inoculation loop in the inoculation loop container 2 and makes it pass through the pop-up hole 11 and pop out (for example, at this time the inoculation loop clamp 33 is in the position shown on the left side); Figure 1 (As shown on the right). After the operator takes the popped-out disposable vaccination ring, the above operation can be repeated to pop out subsequent disposable vaccination rings.
[0023] In a preferred embodiment of this application, the lowest point of the bottom surface of the inoculation ring container 2 is provided with a groove for accommodating a single disposable inoculation ring, such that based on natural sliding on the inclined bottom surface of the inoculation ring container 2 or based on slight shaking by the operator, as long as there are disposable inoculation rings in the inoculation ring container 2, there will always be a disposable inoculation ring in the groove, so that it can be grasped and ejected by the inoculation ring clamp 33.
[0024] In a preferred embodiment of this application, the bouncing component 3 is individually controlled for each inoculation ring container 2. For example, in... Figure 1In the illustrated structure comprising two inoculation loop containers 2, a disposable inoculation loop can be ejected from the corresponding inoculation loop container 2 by pressing either side of the pop-up button 31. Optionally, the operator can press the entire pop-up button 31, thereby ejecting one disposable inoculation loop from each of the two inoculation loop containers 2. This arrangement facilitates experiments requiring different numbers of inoculation loops, allowing the operator to eject at most the same number of disposable inoculation loops as the number of inoculation loop containers 2 at a time. In a further preferred embodiment, different inoculation loop containers 2 contain different disposable inoculation loops, such as disposable inoculation loops of different sizes, specifications, and materials; furthermore, the surface of the pop-up button 31 corresponding to different inoculation loop containers 2 may be labeled with information indicating the disposable inoculation loops within that container 2, allowing the operator to eject the corresponding disposable inoculation loop as needed. Those skilled in the art will understand that the term "disposable inoculation loop" herein can also refer to a disposable inoculation needle.
[0025] In a preferred embodiment of this application, the disposable inoculation loop ejector device further includes a sealing cap for sealing the device. This sealing cap isolates the device from the surrounding environment, allowing it to be sealed and placed in a sterile environment when not in use, thus preventing contamination.
[0026] In a preferred embodiment of this application, the surface of the gripping structure (e.g., the fork-shaped or V-shaped structure as described above) of the inoculation loop clamp 33 is coated with an elastic material (e.g., rubber) to facilitate more stable clamping of the disposable inoculation loop and to facilitate the operator to remove it from the inoculation loop clamp 33.

It should be understood that these examples are for the purpose of elaborating on the implementation of this application in detail and are not intended to limit the scope of this application. The embodiments in this application can be practiced without these specific examples.
