Description

Technical Field

[0001] The utility model relates to the field of scissors, in particular to a pair of scissors used for drug detection. Background Art

[0002] The current global drug control situation remains quite severe, and hair drug detection technology plays an important role in preventing and combating drug crimes. Keratinized biological matrices (such as hair and nails) can absorb and accumulate drugs over time, so a retrospective investigation of past drug use can be conducted. After drugs enter the human body, the drug precursors and their metabolites will migrate from the roots to the tips of the hair as the hair grows, so segmented testing can reflect an individual's drug use at different stages. Compared with urine and blood tests, hair testing greatly extends the drug use tracing period, and has the advantages of long detection timeliness, high accuracy, and not easy to be contaminated.

[0003] When inspectors use existing scissors to cut hair, the shearing force can cause the hair to be simultaneously severed and carried by air currents, causing it to fly and lose the test sample. This can affect the accuracy and reliability of test results, and ultimately hinder the investigation and judgment of the case. Therefore, it is necessary to design a special scissors for cutting hair in drug testing to facilitate the hair cutting operation and prevent problems such as loss of evidence and tedious hair segmentation during hair cutting. Utility Model Content

[0004] To this end, it is necessary to provide a pair of scissors for drug testing to solve the problem that when testers use existing scissors to cut hair, the shearing force will cause the hair to be cut and easily carried by the airflow, causing the hair to splash, resulting in the loss of test samples and affecting the accuracy and reliability of the test results.

[0005] To achieve the above-mentioned purpose, the present invention provides a pair of scissors for drug detection, comprising:

[0006] An upper blade body, comprising an outer surface, an upper cutting edge, a long baffle and an upper fixing portion;

[0007] an upper shear handle, one end of which is fixedly connected to the upper fixing portion;

[0008] A lower blade body, comprising an inner surface, a lower cutting edge and a lower fixing portion;

[0009] a lower shear handle, one end of which is fixedly connected to the lower fixing portion; and the upper blade and the lower blade are hingedly connected to each other;

[0010] The storage component includes a segmented baffle, a box body, a pouring port and a connecting portion, wherein the connecting portion is fixedly connected to the lower blade body, and the segmented baffle is parallel to the lower blade body and is located on the back side of the inner port surface.

[0011] Furthermore, the segmented baffle includes a plurality of sub-baffles, each sub-baffle is parallel to the lower blade body, and each sub-baffle is arranged at a different distance from the lower blade body.

[0012] Furthermore, the inner side of the box body is a horizontally inverted semi-cylindrical structure, and the outer side is a stepped structure that is narrow at the bottom and wide at the top and open at the top, and the box body is formed by combining the inner and outer structures.

[0013] Furthermore, the length of the upper scissors handle is shorter than the length of the lower scissors handle.

[0014] Furthermore, the upper scissors handle and the lower scissors handle are both curved structures.

[0015] Furthermore, the ends of the upper scissors handle and the lower scissors handle are both open structures.

[0016] Furthermore, an elastic layer is included, and the elastic layer is arranged on the inner side of the upper scissors handle and the lower scissors handle.

[0017] Furthermore, the storage assembly is made of an antistatic plastic material; and / or an antistatic film layer is provided on the inner wall surface of the storage assembly. Unlike the prior art, the above-mentioned technical solution of this novel invention has a relatively simple structure and is similar in operation to ordinary scissors, requiring only simple training to master its use. Compared with most ordinary scissors on the market, this scissors has a clear purpose and has obvious advantages in the field of hair drug detection for hair shredding operations. It not only allows for convenient storage and access of hair, but also can quantitatively segment hair according to the processing requirements of hair samples.

[0018] All components of the scissors are made of materials widely available on the market. Generally speaking, the scissors have low production costs, are easy to process, and can be reused after cleaning.

[0019] Based on the above characteristics, the following conclusions can be drawn:

[0020] (1) This design solves the problem of the lack of scissors for cutting hair in drug detection.

[0021] (2) This design improves the efficiency of hair drug detection to a certain extent and enhances the accuracy and reliability of the detection results. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] See also Figures 1 to 5 This embodiment provides a pair of scissors for drug detection, comprising:

[0055] The upper blade body 3 includes an outer surface 31, an upper cutting edge 32, a long baffle 33 and an upper fixing portion 34;

[0056] An upper scissors handle 1, one end of which is fixedly connected to the upper fixing portion 34;

[0057] The lower blade body 4 includes an inner surface 41, a lower cutting edge 42 and a lower fixing portion 43;

[0058] The lower scissors handle 2 has one end fixedly connected to the lower fixing portion 43; the upper blade 3 and the lower blade 4 are hinged to each other;

[0059] The storage assembly 5 includes a segmented baffle 51, a box body 52, a pouring spout 53, and a connecting portion 54. The connecting portion 54 is fixedly connected to the lower blade 4. The segmented baffle 51 is parallel to the lower blade 4 and is located on the back side of the inner opening surface 41. The connecting portion 54 can be connected to the lower blade 4 by welding or by a locking fastener.

[0060] Since hair is light and easy to fly, the ultimate goal of the scissors design is to quickly cut and preserve the hair while achieving quantitative segmentation of the hair, providing convenience for testers and improving the accuracy and reliability of test results.

[0061] The shearing portions of the upper and lower blades 3 and 4 are partial blades, interlaced and fitted together. Axial holes are provided between the upper and lower blades 3 and 4, and the blades are hingedly connected using rivets to achieve the shearing function. The upper portion of the storage assembly 5, namely the segmented baffle 51, can be a single baffle or a hollow rectangular parallelepiped lacking two sides, serving as the hair shredding operation area. The lower portion of the storage assembly 5, namely the box 52, can be a container of any shape, including a semi-cylinder with a bottom surface and a hollow trapezoidal body without an upper bottom surface, forming the storage area. This allows for quantitative segmentation of hair and convenient access.

[0062] The present new blade design includes an upper blade 3 and a lower blade 4. The upper blade 3 includes an outer surface 31, an upper cutting edge 32, a long baffle 33, and an upper connecting portion 54 of the upper blade 3. The lower blade 4 includes an inner surface 41, a lower cutting edge 42, and an upper connecting portion 54 of the lower blade 4. The processing range of the outer surface 31, the upper cutting edge 32, the inner surface 41, and the lower cutting edge 42 is limited to the storage range of the storage assembly 5, avoiding excessive processing of the outer surface 31 and the cutting edge and incurring additional costs. The design of the upper baffle allows the upper blade 3 to fit closely with the lower blade 4 and the storage assembly 5. After the hair is chopped, it is in a relatively closed space, surrounded by the upper baffle and the segmented baffle 51 of the storage assembly 5, and can only enter the storage area of ​​the storage assembly 5 (i.e., fall into the box body 52). After the upper connecting portion 54 of the upper blade 3 and the upper connecting portion 54 of the lower blade 4 are respectively connected and fixed to the upper scissors handle 1 and the lower scissors handle 2, they have good stability and are not prone to problems such as the scissors handle shifting or falling off.

[0063] It should be noted that according to relevant regulations, during the pre-treatment of hair samples, the hair samples must be washed twice with appropriate amounts of water and acetone, followed by shaking. After drying, the hair samples are cut into approximately 1mm segments and pulverized in a freezer grinder to form a powder. Therefore, the distance between the segmentation baffle 51 and the lower blade 4 can be set to 1mm. During shearing, the hair is simply inserted into the storage assembly 5 and pressed against the segmentation baffle 51. Since hair is not completely straight and has some curvature, the final length of the sheared hair should be approximately 1mm, meeting pre-treatment requirements and achieving the function of quantitative hair segmentation.

[0064] After the hair is cut into pieces, the functions of storage and removal need to be realized. In most cases, the right hand is the dominant hand, and the thumb is on top and the other four fingers are on the bottom to cooperate in the operation. When cutting, the hand is tilted to the right (that is, the palm is offset upward, not completely upward). During the cutting process, the hair will fall into the box body 52 under the influence of gravity, and the hair storage function can be realized.

[0065] Hair is small and easily sticks to the corners of the storage space. Therefore, the box body 52 is designed. The inner side of the box body 52 is a horizontally inverted semi-cylindrical structure, and the outer side is a stepped platform structure that is narrow at the bottom and wide at the top and open at the top. The box body 52 is formed by combining the inner and outer structures, that is, a combination of a semi-cylinder (with a bottom surface) and a hollow trapezoid (without an upper bottom surface). The 135° dumping platform can prevent dead angles less than 90°, solving problems such as hair stuck and difficulty in cleaning. After the shredded hair enters the box body 52, the shredded hair is poured out through the dumping platform, thereby realizing the hair removal function.

[0066] Furthermore, the segmented baffle 51 comprises multiple sub-baffles, each parallel to the lower blade 4 and spaced at varying distances from the lower blade 4. By providing multiple sub-baffles with varying spacing, it is possible to achieve segmented hair shearing to meet varying requirements. For example, with a spacing of 1 mm, three sub-baffles with spacings of 1 mm, 2 mm, and 3 mm could be provided, increasing versatility.

[0067] The symmetrical straight handles of traditional scissors require the wrist to be in a state of ulnar deviation during operation, which is physiologically difficult for people to adapt to. In this state, the hand strength cannot be fully exerted, which limits the improvement of work efficiency. Therefore, the angle of the handles should be changed to adapt to the characteristics of the human wrist. When holding the scissors, the thumb is on the left side of the upper handle 1. Therefore, in order to adapt to the characteristics of the human wrist and fingers, the handles are bent, that is, the upper handle 1 and the lower handle 2 are both curved structures or the length of the upper handle 1 is less than the length of the lower handle 2, so that the thumb can be in a left position relative to the lower handle 2 or the four fingers, which can greatly improve the problem that the symmetrical straight structure of the handles of traditional scissors is not physiologically adapted. At the same time, in order to adapt to the different hand sizes of different operators, the ends of the upper handle 1 and the lower handle 2 are both open structures, which can leave extra space for the fingers.

[0068] When operating scissors, prolonged operation or improper operation may cause finger pain or even injury, which will not only reduce work efficiency, but may also cause deformation due to operational errors and even affect the accuracy of the test results. Therefore, preferably, the grip of the scissors should be attached with a soft material to improve the user experience. In some embodiments, an elastic layer 7 is also included. The elastic layer 7 is arranged on the inner side of the upper scissors handle 1 and the lower scissors handle 2, that is, the elastic layer 7 is attached to the grip part of the upper scissors handle 1 or the lower scissors handle 2 to reduce hand pain and improve the user experience. The elastic layer 7 can be made of existing flexible plastic or fiber materials, such as soft PVC material, which is easy to shape, soft in texture, and widely used. The soft PVC material is attached to the upper scissors handle 1 or the lower scissors handle 2 to reduce hand fatigue during operation and improve comfort.

[0069] Generally, the upper blade 3 and the lower blade 4 can be made of materials such as stainless steel, low carbon steel, carbon tool steel, etc. In this design, in order to avoid contaminating the hair sample, the scissors need to be washed and cleaned, so the upper blade 3 and the lower blade 4 are made of stainless steel, which has good rust resistance, is environmentally friendly and durable.

[0070] There are many options for the preparation materials of the upper scissors handle 1 and the lower scissors handle 2, such as PP, ABS rubber, PVC and other materials. In order to avoid contamination of the hair sample, non-toxic and harmless materials should be selected. Among them, PP (polypropylene) plastic products will precipitate lubricants and plasticizers added by the manufacturer under high-temperature heating conditions. However, there is no high-temperature heating during the operation of the scissors designed in this invention, so PP material can be selected, which has the advantages of easy processing, corrosion resistance, and light weight.

[0071] The storage assembly 5 can be made of plastic to reduce weight and cost. Plastic has good insulating properties, but this also means that plastic easily generates static electricity when rubbed, which is difficult to dissipate through conduction. When the scissors are used to cut hair, the box body 52 will constantly rub against the hair, which can easily generate static electricity.

[0072] The hazards of static electricity can be prevented by reducing and preventing friction to reduce the generation of static charges or by allowing static charges to leak away quickly. Among antistatic methods, adding antistatic agents to plastics is the simplest and most effective method, with low cost and wide application. This pair of scissors is designed to be reusable. In order to avoid contaminating hair samples, repeated washing before use is necessary, so it is necessary to select antistatic agents that are resistant to washing and friction. Among antistatic agents, internally added polymer antistatic agents have the advantages of being resistant to washing and friction. They are widely used in PE and PP resins. They are added to the resin during the batching process, migrate from a uniform distribution in the polymer to the outer surface, and form a uniform antistatic layer on the surface.

[0073] In some embodiments, the storage component 5 is made of antistatic plastic material, and / or an antistatic film layer is provided on the inner wall surface of the storage component 5. The antistatic film layer can be an antistatic plastic film or an aluminum foil layer.

[0074] The operation method of the present invention is as follows: when in use, the operator uses the dominant hand (usually the right hand) as the operating hand, with the thumb on top and the index finger, middle finger, ring finger, and little finger at the bottom for operation in any combination. The operator holds the hair with the other hand (take good protection or use tweezers to pick it up) and inserts the hair into the storage component 5 and presses against the segmented baffle 51. The operator exerts force to control the upper cutting edge 32 and the lower cutting edge 42 to rotate around the hinge to cut the hair. The cut hair falls into the box body 52. ​​After the hair sample is cut into pieces, the operator turns left and pours the cut hair out through the pouring port 53.

[0075] The structure of this new type of scissors is relatively simple, and the operation method is similar to that of ordinary scissors. It can be used proficiently after simple training. Compared with most ordinary scissors on the market, this type of scissors has a clear purpose and has obvious advantages in cutting hair in the field of hair drug detection. It can not only realize convenient storage and access of hair, but also quantitatively segment hair according to the processing requirements of hair samples.

[0076] All components of the scissors are made of materials widely available on the market. Generally speaking, the scissors have low production costs, are easy to process, and can be reused after cleaning.

[0077] Based on the above characteristics, the following conclusions can be drawn:

[0078] (1) This design solves the problem of the lack of scissors for cutting hair in drug detection.

[0079] (2) This design improves the efficiency of hair drug detection to a certain extent and enhances the accuracy and reliability of the detection results.
