Description

Technical Field

[0001] The present invention relates to the technical field of acupoint identification, and in particular to a device and method for identifying acupoints using fluorescence and thermal imaging technologies. Background Art

[0002] In traditional Chinese medicine meridian theory, the function of meridians is to communicate the inside and outside, and to circulate the qi and blood. Acupoints are the functional points on the meridians. Diseases in various parts of the body can be reflected by the acupoints on the meridians. However, in the prior art, the bone measurement method is often used to identify acupoints. The length or width between different parts of the human body is converted into several equal parts according to a certain ratio, and each equal part is 1 inch. This is used as a standard to determine the location of the acupoints. In actual operation, it is difficult to accurately measure the bone measurement, especially when the human body is in different postures and different physiological states, the measured length may be biased. For example, when measuring the length of the upper limb to determine the acupoints, the flexion and extension state of the arm will affect the measurement results; the prior art also uses the finger-to-body measurement method, which uses the patient's own fingers as the size standard to measure the acupoints, including the middle finger-to-body measurement (the width between the inner two ends of the middle section of the middle finger is taken as 1 inch when the middle section is flexed), the thumb-to-body measurement (the width of the thumb knuckle is taken as 1 inch), and the horizontal finger-to-body measurement (put the index finger, middle finger, ring finger and little finger together, and take the horizontal line of the middle section of the middle finger as the standard, and the width of the four fingers is 3 inches). However, the length and width of fingers of different individuals are different, such as the finger sizes of children and adults, men and women are different, which makes it not accurate enough to measure acupoints using fingers as the standard, which may lead to errors in acupoint positioning, and in special circumstances, such as when the patient's hand is injured or the fingers cannot be stretched normally, this method cannot be implemented, limiting its scope of application. Based on the above reasons, a device and method for identifying acupoints using fluorescence and thermal imaging technology are designed. Summary of the invention

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a device and method for identifying acupoints using fluorescence and thermal imaging technology.

[0012] By adopting the above solution, the rotation of the threaded rod drives the slider to move, and then drives the integrated board to move, thereby achieving a horizontal and all-round acupoint recognition effect.
