Description

Technical Field

[0001] The utility model relates to the field of positioning equipment, in particular to a head-mounted scalp and hair precision positioning ruler. 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 dermatology lens dermatology testing, especially for efficacy evaluation, requires regular monitoring and comparison of hair growth at the same location. Since scalp positioning is based on an irregular spherical surface, the random positioning location is unique to the individual being tested and is also unique relative to fixed points 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 cannot randomly locate, resulting in significant limitations. Without additional positioning methods, accurate positioning cannot be achieved to allow for regular observation of hair changes in the same area. While existing intelligent detection equipment positioning methods can address the issue of not being able to select the same location for testing, they require additional connection to a positioning and laser emission system, resulting in complex structures, cumbersome operation, and high procurement costs, hindering widespread adoption. Utility Model Content

[0004] The utility model provides a head-mounted scalp hair precision positioning ruler, which aims to solve the problem that there is no simple and effective positioning device when detecting hair through skin lens, and it is impossible to ensure that multiple detections are at the same scalp position when diagnosing hair diseases and evaluating treatment effects.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A head-mounted scalp and hair precision positioning ruler comprises a fixed ruler with fixing straps connected at both ends, a convex groove provided on the outer surface of the fixed ruler, a slider connected to the convex groove that can slide along the convex groove, and a positioning ruler vertically connected to the top of the slider; both the fixed ruler and the positioning ruler are soft rulers with scales.

[0007] Furthermore, the fixing belt is an elastic belt.

[0008] Furthermore, a positioning hole is provided in the middle of the positioning ruler.

[0009] Furthermore, the positioning hole is in a long strip shape.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 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.

[0012] 2. When using the positioning device provided by the utility model, the center of the fixed ruler is aligned with the center of the eyebrows, and the two sides are placed at the base of the ears. The three points of the commonly used human body surface landmarks, the center of the eyebrows and the base of the ears, are connected to form a virtual plane as the fixed point. No external fixed bracket or reference point is required, and positioning is performed by relative distance, without the need for laser positioning. The device is simple, low in production cost, easy to operate, highly accurate in positioning, and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a schematic structural diagram of the positioning device of the present utility model;

[0014] In the figure: 1-fixed ruler; 2-slider; 3-fixed belt; 4-positioning ruler; 5-groove; 6-positioning hole. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figure 1 As shown, the utility model is a head-mounted scalp and hair precision positioning ruler, comprising a fixed ruler 1, with an elastic fixing strap 3 connected to both ends of the fixed ruler 1, a convex groove 5 provided on the outer surface of the fixed ruler 1, a slider 2 that can slide along the convex groove 5 is connected to the convex groove 5, a positioning ruler 4 is vertically connected to the top of the slider 2, and a long strip-shaped positioning hole 6 is provided in the middle of the positioning ruler 4; the fixed ruler 1 and the positioning ruler 4 are both plastic soft rulers with scales.

[0017] To use, first align the center of the fixed ruler 1 with the center of the eyebrows, then place the two sides of the fixed ruler 1 at the base of the ears, and finally place the fixing strap 3 behind the head to secure it. Next, select the dermatoscope examination site, move the slider 2 along the convex groove 5, and press down the positioning ruler 4 until the long, central positioning hole 6 of the positioning ruler 4 coincides with the examination site. Mark the location with a marker, and simultaneously record the scales of the fixed ruler 1 and the positioning ruler 4. Once the positioning is complete, begin dermatoscope examination. The next time you perform a test, mark the same distance with the marker and begin dermatoscope examination, thereby regularly observing changes in hair in the same area.
