Description

Technical Field

[0001] The utility model relates to the technical field of cleaning test tubes, in particular to a device for cleaning test tubes for testing the antibacterial performance of microorganisms. Background Art

[0002] Antimicrobial textiles refer to fibers or fabrics that have a killing or inhibitory effect on microorganisms such as bacteria, fungi and viruses. In recent years, the amount of textiles sent by enterprises to testing agencies for antimicrobial properties has also increased. The testing and evaluation of the antimicrobial properties of antimicrobial textiles is very important for regulating the antimicrobial market and protecting consumer health.

[0003] At present, the common antibacterial performance evaluation standards for antibacterial textiles are mainly the series of standards issued by the American Textile Printers and Chemists Association, the American Society for Testing and Materials, the Japanese Industrial Standards, the International Standards Organization, the National Standardization Administration of my country, and the Textile Industry Association, which mainly involve three aspects: qualitative detection methods, quantitative detection methods, and safety evaluation. In terms of quantitative detection, the commonly used standards for antibacterial performance detection in my country are the GB / T20944 "Evaluation of Antibacterial Performance of Textiles" series of standards and FZ / T73023-2006 "Antibacterial Knitwear". Among them, the oscillation method is suitable for non-dissolving antibacterial textiles and samples with poor water absorption. It has the advantages of accurate quantitative results and reliable results and is the most widely used.

[0004] In the antibacterial performance test of the oscillation method, the prepared sample bacterial solution and the control sample bacterial solution must be diluted to an appropriate concentration before being transferred to the culture dish. When performing gradient dilution operations, many 10mL test tubes with rotating lids are used. For example, E. coli culture usually needs to be diluted from the original solution to 10 -5 ~10 -6 concentration (a single parallel sample requires 5 to 6 test tubes), Candida albicans culture usually needs to be diluted from the original solution to 10 -3 ~10 -4 concentration (a single parallel sample requires 3 to 4 test tubes). The culture of Staphylococcus aureus usually needs to be diluted from the original solution to 10 -3 ~10 -4Concentration (3 to 4 test tubes are required for a single parallel sample). According to the standard requirement of 3 parallel samples, 33 to 42 test tubes are required for one sample. If a batch of 25 samples is calculated, the number of test tubes used in the entire batch will reach about 1,000. There are usually two ways to clean so many test tubes. One is manual cleaning, which involves unscrewing the caps of 5 to 6 test tubes and taking them out, then rinsing them with water and placing the test tubes in the rack, and then unscrewing the caps of 5 to 6 test tubes and rinsing them with water. Due to the lack of effective cleaning fixtures, this method is time-consuming and labor-intensive. The second method is to use an automatic bottle washer for washing. The automatic bottle washer requires people to unscrew the caps of the test tubes and pour out the solution inside, and then neatly place them on the rack of the bottle washer (the number of racks of the current automatic bottle washer is usually 300 to 500), and then set the washing method and start the cleaning operation. After cleaning, the clean test tubes need to be taken out of the bottle washer one by one and placed in a special test tube basket. The cost of automatic bottle washing machines is high (about 150,000 to 300,000 yuan per machine), and a lot of manpower is consumed in the process of rotating the test tube caps, placing the test tubes, and removing the test tubes. Utility Model Content

[0005] In order to solve the above problems in the prior art, the utility model provides a device for cleaning a test tube for testing the antibacterial performance of microorganisms, which can effectively save labor and reduce costs for cleaning the test tube.

The partition is arranged in the basket to divide the basket into a plurality of placement areas. The cover is detachably connected to the inner wall of the basket.

[0008] The beneficial effect of the utility model is that after screwing the caps of the bottles to be cleaned, a handful can be grabbed at one time and directly turned upside down in the placement area of ​​the basket, and due to the effect of the partition, the test tubes can be effectively prevented from tilting, thereby ensuring the placement efficiency of the test tubes. After the bottles are placed, the cover plate is put on and the basket is turned over. The cover plate can support the bottles placed in the basket to fix them, and the test tubes placed in the basket can be rinsed. After washing, the basket can be directly taken to the oven for drying and disinfection. The device is not only low-cost, but also saves time and labor, and greatly improves the cleaning efficiency.

[0009] Preferably, the partition has a M-shaped blade structure, and each blade of the partition has an arc shape.

[0010] From the above description, it can be seen that each blade of the partition is in the shape of an arc surface, which can better fit the shape of the test tube wall and ensure the stability of the test tube placement.

[0011] Preferably, first handles are respectively provided on both sides of the outer circumference of the basket.

[0012] It can be seen from the above description that by providing the first handle, it is convenient for the user to carry the basket.

[0016] From the above description, it can be seen that the screw connection between the cover and the inner wall of the basket can facilitate fixing the position of the test tube in the basket, and the screw connection height can be adapted according to the height of the test tube; in addition, the detachable connection between the partition and the inner wall of the basket is achieved by screwing, which is simple and convenient to implement.

[0017] Preferably, a foot pad is provided at the bottom of the basket.

[0018] Preferably, it also includes a cleaning equipment group;

[0019] The cleaning equipment group includes a spray device, an ultrasonic cleaning machine, a PLC controller, a water inlet solenoid valve and a water discharge solenoid valve;
