A mixed microbial kit capable of preventing cross-infection

Abstract

This utility model discloses a mixed microbial reagent kit that can prevent cross-infection, including a box body. The box body has a tube rack inside, with through grooves evenly distributed in the middle of the tube rack. Guide rails located on both sides of the through grooves are fixedly installed on the top of the tube rack. A movable frame is slidably connected to the top of the guide rails. A pull button is slidably connected through the middle of the top of the movable frame. A lifting plate located inside the movable frame is fixedly installed at the bottom of the pull button. The lifting plate is slidably disposed within the movable frame. Downward pressure springs are located on both sides of the pull button on the top of the lifting plate. A sealing sheet abuts against the top of the test tube to seal it. Simultaneously, an insertion rod engages with the insertion hole on the guide rail. During placement and movement, the movable frame moves, ensuring the sealing effect of the reagent tubes. Furthermore, the handling of a single reagent tube does not affect the sealing of other reagent tubes, thus preventing cross-infection of mixed microorganisms.

Description

Technical Field

[0001] This invention relates to the field of microbial reagent kit technology, specifically a mixed microbial reagent kit that can prevent cross-infection. Background Technology

[0002] In long-term experimental and production practices, many biological processes cannot be completed or can only be carried out weakly by pure microbial culture and must be completed by co-culturing two or more microorganisms. For the biodegradation of many industrial pollutants, biopesticides, cellulose, and chitin, mixed microbial culture is necessary. Mixed microbial culture can be used for the fermentation production of vitamin C, vitamin B12, histidine, valine, malic acid, etc., and can also be used for the steroidal conversion of pharmaceuticals, biogas fermentation, hydrometallurgy, etc.; mixed microbial resources are receiving increasing attention.

[0003] The mixed microbial reagent kit is used to hold reagent tubes. Glass reagent tubes are preferred for the culture of mixed microorganisms. The tubes are sealed with stoppers. The mixed microorganisms should be of a stable species, and cross-infection should be prevented. However, if the stopper becomes loose during the movement of the kit, cross-infection of microorganisms will occur, affecting the culture effect of mixed microorganisms.

[0004] In the prior art, utility model patents with publication number CN218506444U (a mixed microbial reagent kit with good anti-cross-infection effect), CN216039619U (a microbial reagent kit for easy classification and screening), and CN216547420U (a multifunctional reagent kit for microbial fermentation experiments) can all achieve common sealing and common reinforced sealing of reagent tubes. However, they all adopt a uniform sealing structure. Once the lid is opened, the sealing effect of each reagent tube cannot be guaranteed, which is not conducive to preventing cross-infection of microorganisms.

[0005] Therefore, we propose a mixed microbial kit that can prevent cross-infection. Utility Model Content

[0006] The purpose of this invention is to provide a mixed microbial reagent kit that can prevent cross-infection, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mixed microbial reagent kit that can prevent cross-infection, comprising a box body, wherein a tube rack is provided inside the box body, a through groove is evenly opened in the middle of the tube rack, a guide rail is fixedly installed on the top of the tube rack on both sides of the through groove, a movable frame is slidably connected to the top of the guide rail, a pull button is slidably connected through the middle of the top of the movable frame, a lifting plate is fixedly installed at the bottom of the pull button inside the movable frame, the lifting plate is slidably disposed with the interior of the movable frame, a pressure spring is provided on the top of the lifting plate on both sides of the pull button, a sealing sheet is adhered to the bottom of the lifting plate, and plug rods on both sides of the sealing sheet are fixedly installed on the bottom of the lifting plate, and plug holes corresponding to the plug rods are opened on the top of the guide rail.

[0008] Optionally, the box body is fixedly installed with side pads located around the tube rack. One side of the side pad is fixed to the inner wall of the box body, and the other end of the side pad is pressed against the outside of the tube rack.

[0009] Optionally, a bottom pad is provided at the bottom inside the tube rack, and a placement groove corresponding to the through groove is opened on the top of the bottom pad. The bottom pad is a rubber pad.

[0010] Optionally, the sealing sheet is a silicone sheet, and the width and length of the sealing sheet are greater than the diameter of the through groove.

[0011] Optionally, an ice box is provided in the middle of the side pad, grooves are provided on both sides of the ice box, and a protrusion is provided in the middle of the side pad for placing the ice box. The ice box is fixedly installed to the side pad through the grooves and the protrusion.

[0012] Optionally, the top of the compression spring is abutted against the top of the interior of the movable frame, and the bottom of the compression spring is abutted against the top of the lifting plate.

[0013] Optionally, the pull button includes a long rod fixedly installed to the top of the lifting plate, and a pull head fixedly installed to the top of the long rod. The long rod of the pull button is slidably connected through the top of the movable frame, and the pull head of the pull button is located above the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This mixed microbial reagent kit, designed to prevent cross-infection, utilizes a guide rail and a sealing plate. After placing the test tube into the through slot of the tube rack, pulling the lever moves the moving frame along the guide rail, causing the lifting plate and sealing plate to move above the test tube. Releasing the lever allows the lifting plate to move downward under the action of the spring, pressing the sealing plate against the top of the test tube to seal it. Simultaneously, the insertion rod engages with the insertion hole on the guide rail. The kit's movement during the kit's operation ensures a tight seal on the reagent tubes, and the placement or removal of individual reagent tubes does not affect the sealing of other reagent tubes, thus preventing cross-infection from mixed microorganisms.

[0016] 2. This mixed microbial reagent kit, which can prevent cross-infection, has side pads that provide good protection for the tube rack, ensuring the stability of the mixed microorganisms during kit movement. Placing an ice box and creating a low-temperature environment is also beneficial to the stability of the microorganisms. Attached Figure Description
