Description

Technical Field

[0001] The utility model relates to the field of positioning equipment, in particular to a positioning device for skin lens hair detection. Background Art

[0002] A dermatoscope is a skin microscope that can magnify dozens of times. Its function is the same as that of an ophthalmoscope used in ophthalmology and an otoscope used in otolaryngology. It is a powerful tool for observing skin pigmentation diseases. It has the characteristics of being non-invasive, magnifying, and having perspective. It is of great significance in the diagnosis, identification, and efficacy evaluation of hair diseases.

[0003] Clinical dermatological lens dermatology, especially when evaluating treatment efficacy, requires regular monitoring and comparison of hair growth at the same location. Because scalp mapping is performed on an irregular spherical surface, the random location is unique to the individual being tested and also unique relative to a fixed point on the scalp. Therefore, ensuring multiple measurements of the same location for a given subject is challenging. Currently, some physicians use scalp tattooing methods, such as tattooing with liquid puncture, for accurate positioning. However, this method leaves a permanent mark, which can affect appearance when hair is thinning. Others use anatomical locations on the scalp, such as the Baihui acupoint, or physiological hair features such as hair whorls and temples. However, these methods can only locate specific, prominent locations and are not capable of random positioning, resulting in significant limitations. Without additional positioning methods, accurate positioning cannot be achieved to regularly observe hair changes in the same area.

[0004] A Chinese utility model patent with application number 202021472982.1 was retrieved, which discloses a scalp hair precision positioning device, which can solve the problem that the same position cannot be selected each time the skin lens hair is detected. However, this device needs to be connected to an external bracket, positioning and laser emission system, computer system, etc. The structure is complex and the operation is cumbersome. It cannot be widely promoted and used, and there is currently no clinical application. Utility Model Content

[0005] The utility model provides a positioning device for skin lens hair detection, which aims to solve the problem that there is no simple and effective positioning device during skin lens hair detection, and it is impossible to ensure that multiple detections are at the same scalp position during hair disease diagnosis and treatment evaluation.

[0006] To achieve its purpose, the utility model adopts the following technical solutions:

[0007] A positioning device for skin lens hair detection includes a semicircular angle ruler, two ends of the bottom of the angle ruler are connected to fixing belts, the center of the bottom of the angle ruler is vertically connected to a midline ruler, and the center of the bottom of the angle ruler is movably connected to a positioning ruler.

[0008] Furthermore, the fixing belt is an elastic belt.

[0009] Furthermore, the positioning ruler is a plastic soft ruler.

[0010] Furthermore, a positioning hole is provided in the middle of the positioning ruler.

[0011] Furthermore, the positioning hole is provided with a scale.

[0012] Furthermore, the positioning hole is in a long strip shape.

[0013] Furthermore, the angle ruler and the positioning ruler are hinged via a positioning pin.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The positioning device provided by the utility model can accurately locate the hair detection position of the dermatoscope, ensuring that multiple detections are at the same position, solving the problem of multiple dermatoscope hair detection positions not being unique, and achieving the purpose of regularly observing the changes in hair in the same part.

[0016] 2. The positioning device provided by the utility model uses the center point of the eyebrow as a fixed point or reference point when in use, does not require an external fixed bracket or reference point, and is positioned by relative angle and distance, does not require laser positioning, is simple in device, low in production cost, easy to operate, has high positioning accuracy, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a schematic structural diagram of the positioning device of the present utility model;

[0018] In the figure: 1-angle ruler; 2-center line ruler; 3-fixing belt; 4-locating pin; 5-locating ruler; 6-locating hole. DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1 As shown, the utility model is a positioning device for skin lens hair detection, including a semicircular 180 o An angle ruler 1 has an elastic fixing strap 3 horizontally connected to each end of the bottom of the ruler. A centerline ruler 2 is fixed vertically downward at the center of the bottom of the ruler 1. A positioning ruler 5 is hinged at the center of the bottom of the ruler 1 via a positioning pin 4. The positioning ruler 5 is a plastic soft ruler with a long positioning hole 6 in the middle, which is marked with a scale.

[0021] To use, first align the center of the angle ruler 1 with the center of the eyebrows to ensure accurate positioning. The bottom horizontal line of the angle ruler 1 should coincide with the eyebrows. Adjust the midline ruler 2 to coincide with the midline of the nose. Then, place the fixing strap 3 behind the head to secure it. Then, select the dermatoscope test site, rotate the positioning ruler 5 so that the long, central positioning hole 6 coincides with the test site, mark the location with a marker, and record the angle of the angle ruler 1 and the scale of the positioning ruler 5. Once the positioning is complete, begin dermatoscope testing. The next time you test, mark the same angle and distance with the marker and begin dermatoscope testing. This allows you to regularly observe changes in hair in the same area.
