Description

TECHNICAL FIELD

[0001] The utility model relates to hair drug detection technical field, concretely is a kind of hair fast sampling device for drug detection. BACKGROUND

[0002] Hair detection is the routine way of drug detection, hair detection can detect whether a person is drug abuse in a long period of time, and some new drugs can also be detected, and the sampling difficulty is low, and the detection precision is high, therefore, when suspicious personnel are detected for drugs, their hair is usually extracted as a sample for detection, and drug detection by hair is widely used in Chinese judicial organs.

[0003] The patent document with publication number CN220477611U discloses a hair detection sampling device, which includes two hingedly connected scissors bodies and a hair collecting box. The scissors bodies have blades and handles arranged on both sides of the hinge connection between the two scissors bodies. The blades of the two scissors bodies can cooperate with each other to cut hair. The hair collecting box has a bottom plate and a side wall connected to the bottom plate. One side of the side wall is provided with an opening, and the side end of the bottom plate near the opening is detachably installed on the outside of any of the blades. Compared with the prior art, the hair detection sampling device is more convenient to operate, and the cut hair is less likely to scatter and fall off. However, the prior art still has the following defects:

[0004] The existing device cannot cut hair of a fixed length. According to the "Hair Sample Detection Specification for Drug-Involved Personnel" (Public No. 938 of 2018, hereinafter referred to as "Specification"), when extracting a hair sample, the staff should wear disposable gloves and use a medical scissors or a sawtooth scissors to cut the hair within 3 cm from the scalp surface of the person being tested at the back of the head (if the back of the head cannot provide enough hair, the nearest part of the head can be selected). Hair longer than 3 cm needs to be cut 3 cm from the root end. However, the existing device uses a conventional scissors to cut the hair of the person being tested, and then the length is measured by visual inspection for secondary trimming, resulting in a hair sample of the required length. This hair collection process requires multiple trimming, increasing the workload of the staff, increasing the difficulty of work, and reducing the work efficiency. The entire operation process is complex, and the hair samples obtained often have different lengths with large differences, which affects the accuracy of the test results. UTILITY MODEL CONTENTS
