Problems solved by technology

The traditional method is to cut the hair with scissors, put it into a sample bag, and then send it to the testing agency. After the testing agency gets the sample, it needs to continue processing, such as continuing to cut or organize, and then carry out chemical reagent treatment to dissolve the hair. Analytical substances, which bring a lot of inconvenience to the handling of samples

Embodiment 1

[0084] Embodiment 1 hair sample collection device provided by the present invention

[0085] The hair sample collection device provided in this embodiment is as Figure 1~6 shown, where figure 1 is the overall structure diagram of the hair sample collection device, figure 2 is a cutaway view of the hair sample collection device, image 3 An exploded view of the hair sample collection device, Figure 4 It is a structural schematic diagram of the hair cutting unit of the hair sample collecting device, Figure 5 It is a structural schematic diagram of the hair quantitative collection unit of the hair sample collection device, Image 6 It is a schematic diagram of the hair sample collection device in the sampling state.

[0086] The device for collecting hair samples provided in this embodiment includes a hair cutting unit 1, a quantitative hair collection unit 2 and a piston structure 3; the hair cutting unit 1 is assembled with the hair quantitative collection unit through...

Embodiment 2

[0111] Embodiment 2 Detachable collection platform

[0112] This embodiment adopts the hair sample collection device as provided in Embodiment 1, wherein the collection platform 16 in the hair quantitative collection unit 2 is connected to the quantitative hole 15 in a detachable manner, and after the sampling is completed, the collection platform is disassembled from the base 16, thus completing the sampling.

Embodiment 3

[0113] Embodiment 3 Obtaining hair samples of different sizes

[0114] In this embodiment, the hair sample collection device as provided in Embodiment 1 is adopted, and the distance between the two sets of blades is 12 cm.

[0115] The method for collecting hair samples using the hair sample collection device provided in this embodiment comprises the following steps:

[0116] 1) Put the hair in the quantitative hole 15. Due to the size limitation of the quantitative hole 15, the amount of hair that can be loaded each time is basically the same. Press the hair cutting unit 1 to cut the hair at the same time through two sets of blades 9 to obtain a length of 8 cm. , a consistent number of hair samples that are neatly arranged;

[0117] 2) The hair is taken out for subsequent processing and detection. The subsequent processing includes extracting the analyte in the hair with chemical reagents, such as for drug analysis.
