Sanquan Zhongshi Medical Co., Ltd. fully implements the needle needle rigid tester GXY-02 which is developed and manufactured in accordance with the GB18457-2015 standard. It is used for disposable injection needles for human intradermal, subcutaneous, muscle and vein and hard stainless steel needles for other medical devices. The determination of the deflection value is also called a medical injection needle (needle) rigidity tester, a medical injection needle (needle) rigidity tester, a medical needle rigid tester, and a medical injection needle rigidity tester.
Medical injection needle needle rigidity tester
The medical needle needle rigid tester GXY-02 uses the dial gauge digital display displacement range, and collects the data through the dial gauge interface to the LCD display. It has the advantages of intuitive display, high precision, and digital display of the force of the needle tube. Deflection.
First, place the meter horizontally on the test bench; select the span block that matches the needle to be tested, and install it on the sensor; plug the power plug into the power distribution board, and place the power socket on the power distribution board. The wire must be reliably grounded.
Calculate the measured deflection: Select the model and load value of the needle to be tested on the main menu.
For example, a 0.7mm needle with a loading force of 10N and a needle placed on a 15mm span block, turn on the power switch of the dial gauge, set the metric conversion button to the mm stop, and then enter the test, when the needle is just under stress Write down the reading of the dial gauge (the dial gauge has a short pause time);
For example, -0.200, when the loading force value is reached, the dial gauge will observe that the large value of zui is, for example, -0.620, and the displacement measured on the dial gauge is 0.620 mm - 0.200 mm = 0.420 mm, and then subtracted. One sensor is subjected to force displacement, 0.011mm at 10N (check the verification report);
Then the deflection of the needle tube is 0.420mm-0.011mm=0.409mm, and the error should be no more than ±0.005mm compared with the measured deflection on the liquid crystal display.
