Acupuncture is a unique Chinese means of treating diseases, and the most important tool for acupuncture is acupuncture needles
.
Acupuncture acupuncture is directly acting on the human body, for the quality of acupuncture needles this country is a mandatory standard requirements, the quality of acupuncture needles to detect the need to use professional acupuncture needle testing equipment, today Weixia Technology will take you together to see what aspects of the national standard for acupuncture needles to do requirements
.
The national standard of acupuncture acupuncture is GB 2024-2016 acupuncture needles
.
The production standard of acupuncture needle tester is designed and manufactured according to the relevant provisions in GB 2024-2016
.
In GB 2024-2016 acupuncture acupuncture national standard, detailed requirements
are made for the type of acupuncture needle, the basic size of the needle diameter, the basic size of the needle length, the diameter of the wire around the handle, the appearance, the physical properties, the chemical properties, the biological properties and the test methods of various properties.
Here we will give you a detailed explanation
of the physical properties of acupuncture needles.
The physical performance requirements of acupuncture needles 1, the hardness of acupuncture needles requires that the needle body hardness of acupuncture needles should comply with the provisions of Table 5 2, acupuncture needle tip performance acupuncture acupuncture needle tip part should be round, no burrs, curved hooks and other defects, after applying the specified force and steel block contact top pressure, its piercing force should not be greater than the provisions of
Table 6.
The performance of the needle tip is mainly the strength and sharpness of the needle tip, which is tested
according to the prescribed method.
3.
The toughness of acupuncture needle body winds the needle body in a tight spiral circle, winding on a mandrel with a diameter of 3 times the diameter of the needle body in the direction of the spiral, and the length of the needle body is not more than 15 mm wrapped 2 times, and other length specifications are wound 5 times
.
The needle body should have good toughness, and there should be no cracks, breaks, and delamination
after the winding test.
4.
The connection between the needle body and the needle handle should be firm, and the tensile force test should be carried out under the force value specified in Table 8, and the axial displacement of the two shall not be greater than 3 mm
.
Test method: first measure the length of the needle body, and then fix the needle body in the fixture, and slowly add force along the axis of the needle body on the end face of the needle handle for non-impact tensile test to the force value specified in the table, and then measure the length
of the needle body.
Acupuncture needle tester is a professional precision instrument to detect the physical properties of acupuncture needles, and acupuncture needle testers are an important means
to verify the physical properties of acupuncture needles.
The testing instruments for detecting the physical properties of acupuncture needles are: acupuncture needle hardness tester, acupuncture needle toughness tester, acupuncture needle connection firmness tester, acupuncture needle tip strength tester, acupuncture needle tip sharpness tester and other instruments
