Description

Technical Field

[0001] This utility model relates to the field of sterilization technology for liquid suction devices, specifically a liquid suction device tip connector holder. Background Technology

[0002] When culturing cells or microorganisms in the laboratory, aspirating and changing the culture medium is a necessary routine operation. In practice, the used pipette tips are usually placed inside the bottle or on the hook inside the biosafety cabinet or laminar flow hood for easy access.

[0003] A search revealed a laboratory aspirator disclosed in patent application number 202022058373.8, belonging to the technical field of laboratory aspiration devices. It mainly includes a power adapter, an electric vacuum pump, a connecting tube, a filtration flask, a perforated stopper, an inlet tube, and a pipette tip. The power adapter is electrically connected to the electric vacuum pump, and the connecting tube is connected at both ends to the suction port of the electric vacuum pump and the top of the filtration flask, respectively. The filtration flask has a filtration flask support on its side, and the inlet tube is connected at both ends to the filtration flask support and the pipette tip, respectively. It is suitable for rapidly aspirating liquids from experimental equipment such as glass dishes, microplates, petri dishes, slides, ordinary bottles, and bioreactors. It offers fast processing speed, ease of use, and effectively improves experimental efficiency. Furthermore, it is low-cost, and the entire device can be easily disassembled and cleaned. Since the liquid does not pass through the pump body, frequent pump cleaning is unnecessary.

[0004] However, the structure of the aforementioned application documents is complex. The pipette tips commonly used in laboratories are cylindrical. After cleaning, the pipette tips are usually placed on a bottle or hook, which is typically located at the edge of the workbench. The cleanliness level at this location is slightly lower than that in the center of the workbench, making it easy for bacteria to adhere to the tips. When reused, these bacteria may fall into the culture medium, contaminating the cultured material and causing experimental failure, resulting in economic and time losses. In addition, because there are gaps at the contact surfaces when the tips are connected to the pipette tips, culture medium residue may remain on the end face and outer surface of the tip after use. When bacteria are present, they can multiply, increasing the likelihood of contamination during subsequent operations.

[0005] Therefore, we propose a suction tip connector holder. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a suction tip connector holder, which solves the problems of limited sterilization effect and insufficient safety of existing suction devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a suction tip connector holder, including a base, a receiving component is assembled on the top of the base, a sterilization tube is clamped on the base through the receiving component, and a suction tip connector adjustment component located outside the receiving component is also assembled on the top of the base, and the top side of this component has a clip for fixing the suction tip connector inserted into the sterilization tube.

[0008] An LED sterilization lamp is fixedly installed on the inner side of the sterilization cylinder, located on the top side of the suction head connector of the liquid aspirator. An aluminum reflector is also installed on the inner side of the sterilization cylinder, located around the suction head connector of the liquid aspirator. The LED sterilization lamp and the aluminum reflector are spliced ​​into a cylindrical shape, and the curvature of the LED sterilization lamp is one-fifth of the overall curvature of the aluminum reflector. An LED power switch for opening and closing the positioning plug inside the sterilization cylinder is also fixedly installed on the top of the base.

[0009] As a preferred embodiment of this utility model, a positioning plug is press-fitted at the end of the sterilization tube, and a device hole is provided in the middle of the positioning plug, and the liquid aspirator is inserted into the inside of the sterilization tube through the positioning plug.

[0010] The positioning plug is designed to stably limit the position of the aspirator during the installation process, ensuring its stability during sterilization.

[0011] As a preferred embodiment of this utility model, a groove seat is fixedly installed on the front side of the top of the base, the groove seat has a circular slot hole, and a rinsing bottle containing 75% ethanol solution is clamped in the groove seat.

[0012] The design of the trough and its shape facilitates the placement of a rinsing bottle for efficient rinsing and cleaning of the aspirator.

[0013] As a preferred embodiment of the present invention, a receiving component is fixedly installed on the top of the base. The receiving component includes a support column fixedly installed on the top of the base. A fastener is provided on the top side of the support column. A sterilization cylinder is fastened and clamped on the inner side of the fastener. The top of the support column and the bottom of the fastener are assembled by a wing bolt.

[0014] The structure of the receiving component facilitates the mounting of the sterilization cartridge, and also allows for adjustment of the tilt angle of the sterilization cartridge, achieving efficient sterilization of the suction tip connector.

[0015] As a preferred embodiment of this utility model, the main body of the suction head connector receiving assembly is a telescopic column fixedly installed on the top of the base. A clip is provided on the top side of the telescopic column. The clip is a three-quarter arc-shaped clip, and the telescopic column and the clip are assembled together by fastening bolts.

[0016] The design of the suction head connector receiving component facilitates the insertion of the suction device into the sterilization cylinder, ensuring the subsequent sterilization effect.

[0017] This utility model provides a suction tip connector holder. It has the following advantages:

[0018] This pipette tip holder, with its rinse bottle on the base, allows for rinsing and cleaning of the pipettes after use. Simultaneously, the sterilization cartridge uses an LED sterilizing lamp to emit sterilizing ultraviolet light, which, along with an aluminum reflector, efficiently sterilizes the pipette tip connectors from all sides. Compared to the usual methods of placing them in a bottle or hanging them on a hook, this insertion-based sterilization reduces the risk of airborne bacteria adhering to the connectors. The added cleaning and sterilization functions further reduce the survival rate of bacteria attached to the connectors, increasing the safety of experimental operations and solving the problem of limited sterilization effectiveness and insufficient safety in existing pipette systems.
