Abstract
Description
Technical Field
[0001] The present application relates to the technical field of self-contained biological indicators, and in particular to a self-contained biological indicator inoculation tool. Background Art
[0002] Self-contained biological indicators play an important role in confirming sterilization equipment performance, developing sterilization processes for specific items, and monitoring sterilization effectiveness during production. They consist of a specific microorganism and culture medium combination with defined and stable tolerance to specific sterilization procedures. When using self-contained biological indicators, it is necessary to crush the culture medium tube with a pinch to prevent evaporation during incubation. Currently, pressing the removable cap is a common method for controlling culture medium evaporation. By pressing the open cap, sterilant penetration is achieved and culture medium evaporation is controlled during incubation. However, this method has certain drawbacks. First, the cap must be pressed and then the culture medium tube must be crushed with a pinch, doubling the workload. Second, some caps fit tightly, and excessive pressing can cause discomfort or even strain on the operator's hands, impacting both work efficiency and health.
[0003] Therefore, a new self-contained biological indicator inoculation tool is urgently needed to solve the problems existing in the prior art. Utility Model Content
[0004] The purpose of this application is to provide a self-contained biological indicator inoculation tool to address the above-mentioned problems existing in the prior art.
[0005] In order to achieve the above application objectives, this application adopts the following technical solutions: The self-contained biological indicator inoculation tool includes:
[0006] The main body is provided with an opening for placing the biological indicator and a cavity for inserting and placing the biological indicator;
[0007] A top block is located at the top of the cavity and is provided with a guide surface;
[0008] The side protrusions are located on the inner wall of the cavity and are symmetrically arranged;
[0009] Among them, when the biological indicator enters the cavity through the opening, it can swing with its own bottom as the fulcrum. When the biological indicator swings toward the top block, the cap of the biological indicator can be pressed by the guide surface of the top block. At the same time, the side protrusions in the cavity can squeeze the side wall of the biological indicator to break its culture medium tube.
[0010] Furthermore, a bottom support is provided in the cavity for supporting the biological indicator.
[0011] Furthermore, a guide protrusion for guiding the biological indicator is provided in the cavity.
[0012] Furthermore, the guide protrusion corresponds to the bottle cap of the biological indicator.
[0013] Furthermore, the distance between the two side protrusions is smaller than the outer diameter of the biological indicator bottle.
[0014] Furthermore, the main body, the top block and the side protrusions are an integrated structure.
[0015] Furthermore, the main body is provided with two openings. When the biological indicator enters from one opening, it can be squeezed out of the cap and the culture medium tube in the process of being driven to swing to the other opening, and can be taken out from the other opening.
[0016] Furthermore, the main body is made of metal or polymer material.
[0017] Furthermore, the top block is located on the center line of the two side protrusions.
[0018] Furthermore, a notch is provided on the main body.
[0019] Compared with the prior art, this application has the following beneficial effects:
[0020] 1. Improve operational efficiency
[0021] Compared with the prior art which requires pressing the cap before crushing the culture medium tube, the inoculation tool of the present application can simultaneously press the cap and crush the culture medium tube while swinging with its own bottom as the fulcrum after the biological indicator is placed in the cavity, thereby greatly reducing the number of operation steps and improving work efficiency.
[0022] 2. Reduce labor intensity
[0023] In the prior art, some caps fit tightly, and frequent pressing operations may cause discomfort or even strain to the operator's hands. However, the tool of the utility model does not require repeated manual pressing of the cap, thus avoiding the physical burden on the operator caused by repeated operations and reducing labor intensity.
[0024] 3. Reasonable structural design
[0025] A bottom support is provided in the cavity, which can stably support the biological indicator and ensure the stable position of the biological indicator during operation.
[0026] A guide protrusion is provided to guide the biological indicator, and in particular, the guide protrusion corresponds to the bottle cap of the biological indicator, so that the biological indicator can swing and operate accurately according to the designed path.
[0027] The two side protrusions are symmetrically arranged and the distance between them is smaller than the outer diameter of the biological indicator bottle, which can effectively squeeze the side wall of the biological indicator to ensure that the culture medium tube is squeezed and broken.
[0028] The top block is located on the center line of the two side protrusions, ensuring the accuracy and stability of the cap plug pressing.
[0029] 4. The integrated structure is stable and reliable
[0030] The main body, top block and side protrusions are an integrated structure, which enhances the overall strength and stability of the inoculation tool and reduces the possibility of looseness and malfunction between components.
[0031] 5. Wide range of applicable materials
[0032] The main body can be made of metal or polymer materials, with a wide range of material options to meet different usage environments and needs.
[0033] 6. Convenient operation
[0034] The main body has two openings. The biological indicator enters through one opening and can be removed from the other opening after being squeezed by the cap and the culture medium tube during the swinging process, making operation more convenient and smooth. In addition, a notch on the main body further facilitates operation and observation, and also facilitates the demolding of the main body from the mold during the manufacturing process.

Therefore, the above terms cannot be understood as limiting this application.
[0041] like Figure 1-3 As shown, the self-contained biological indicator inoculation kit includes:
[0042] 1. Overall structure
[0043] This self-contained biological indicator inoculation tool primarily comprises a main body 1, a top block 11, and side projections 12. The main body 1 has an opening for inserting the biological indicator 2 and a cavity for inserting and placing the biological indicator 2. The top block 11 is located at the top of the cavity and has a guiding surface (e.g., an inclined surface). The side projections 12 are symmetrically arranged on the inner wall of the cavity.
[0044] 2. Functions and characteristics of each component
[0045] Main body 1: Openings in main body 1 facilitate the insertion and removal of biological indicator 2. Once inserted through one opening, biological indicator 2 can be manipulated within the cavity and then removed through another opening, providing convenient operation. Notch 15 in main body 1 can be used for internal observation or to assist in manipulation, and also facilitates demolding of the main body during the manufacturing process.
[0046] The main body 1 can be made of metal or polymer materials, which have good strength and durability and can adapt to different usage environments. It can be machined, injection molded, or 3D printed.
[0047] Top block 11: The inclined surface of top block 11 is cleverly designed. When biological indicator 2 swings toward top block 11, the inclined surface presses down on its cap 21, controlling sterilant penetration and culture medium evaporation during incubation. This eliminates the need to manually press cap 21, reducing both the number of steps and the labor involved.
[0048] Side protrusions 12: Symmetrically arranged side protrusions 12 are located on the inner wall of the chamber. The distance between the two side protrusions 12 is less than the outer diameter of the bottle body 23 of the biological indicator 2. When the biological indicator 2 swings, the side protrusions 12 can squeeze the side wall of the biological indicator 2, thereby rupturing the culture medium tube.
[0049] Bottom support 13: A bottom support 13 is provided in the cavity to support the biological indicator 2. The bottom support 13 ensures that the position of the biological indicator 2 in the cavity is stable, ensuring the smooth operation process.
[0050] Guide protrusion 14: A guide protrusion 14 is provided within the cavity to guide the biological indicator 2. The guide protrusion 14 corresponds to the bottle cap 22 of the biological indicator 2, allowing the biological indicator 2 to swing and operate accurately along the designed path, improving operational accuracy and reliability.
[0051] 3. Operation process
[0052] The biological indicator 2 is placed into the cavity through the opening on the main body 1. The biological indicator 2 swings in the cavity with its own bottom as the fulcrum. When the biological indicator 2 swings toward the top block 11, the inclined surface of the top block 11 presses the cap 21. At the same time, the side protrusions 12 in the cavity squeeze the side wall of the biological indicator 2, so that the culture medium tube is squeezed and broken. After the operation is completed, the biological indicator 2 can be taken out from the other opening. That is, after the self-contained biological indicator 2 is placed in the cavity from one side, the biological indicator 2 is pushed so that it pops out from the other side. During the pushing process, the lever principle and the action of the inclined surface and the side protrusions 12 are used to simultaneously achieve the breaking of the culture medium tube and the pressing of the cap 21.
[0053] In summary, the self-contained biological indicator 2 inoculation tool of the present invention has a reasonable structural design, is easy to operate, can effectively improve work efficiency, reduce labor intensity, and has good application prospects.
[0054] The parts not described in detail in this application are prior art, so this application does not describe them in detail.
