[0002] Blood culture can identify the pathogen of infection and is the gold standard for determining bloodstream infection. It plays a vital role in clinical treatment and antibiotic management. The correct blood culture specimen collection method can reduce the contamination rate of blood culture specimens and improve the accuracy of test results. At present, clinical blood culture still has common problems such as low blood culture positivity rate and high contamination rate. The causes of blood culture contamination are contamination of blood culture bottle caps, contamination of blood collectors' hands, and improper disinfection of patients' skin.

[0003] Currently, there are no disposable blood culture collection kits for clinical use, despite the extremely high frequency of clinical application. This presents the following problems:

[0004] 1. When collecting blood culture, a variety of items are needed, but these items are placed in a rather scattered manner. The collectors need to pick up items from different places, which not only increases the workload and wastes time, but also leads to incomplete preparation of items.

[0005] 2. There are differences in the collection of blood cultures among various clinical departments. For example, some departments do not require the use of sterile gloves, which may lead to contamination of blood culture collection.

[0006] Chinese patent document application number 201922386906.2 discloses a disposable blood collection and culture tool box. The culture box has a complex structure and unreasonable item configuration. For example, the disinfection and drying time of iodine cotton balls and alcohol cotton balls is long, and the blood collector cannot meet the drying time requirements.
