The syringe includes a body, a needle, a needle tube, a piston, and a needle core. Its characteristic is that finger cots are provided on both sides of the outer arm of the needle tube, which has a simple structure and is easy to use. As a basic medical instrument, its sliding performance directly affects the accuracy of drug injection, patient comfort, and equipment reliability. The sliding tester quantitatively evaluates the friction characteristics between the piston and the outer sleeve, providing a scientific basis for product quality control. The syringe sliding tester developed by Shanghai Yingle manufacturer is suitable for medical device inspection centers and disposable sterile syringe production enterprises. Designed and manufactured in accordance with the relevant standards of GB15810 "Disposable Sterile Syringes".

Usage:

The sliding performance tester is used to evaluate the smoothness of syringe piston sliding, ensuring that it meets medical safety standards. The following steps integrate common operating procedures and cover key links.

preparation

Before testing, it is necessary to check whether the appearance of the syringe is intact, without damage or contamination, and select a matching fixture according to its specifications (such as nominal capacity). Place the tester on a stable workbench, connect the power supply, and start the device. At the same time, prepare purified water as the testing medium, ensure that the water temperature is between 18 ° C and 28 ° C, and add water to the sink to eliminate bubbles.

Installation and parameter settings

Fix the syringe in the fixture, and adjust the position so that the syringe is in good contact with the test platform. Connect the hose, connect the other end to the needle tube and immerse it in water. The water level should be consistent with the middle height of the syringe scale. Set test parameters through the operation interface, including nominal capacity, core rod displacement, test speed (usually 100 mm/min ± 5 mm/min), test frequency, range (such as 0-40 N), and holding time (usually 30 seconds).

Calibration and testing execution

Click on "Zero Position Confirmation" in the testing software for calibration, and manually adjust the mechanical position if necessary to ensure the accuracy of the testing starting point. After starting the test, the instrument automatically pulls the core rod at the set speed to pump water to the nominal capacity line, and records the initial force FMaxSliding force and other data; Subsequently, the core rod is reversed to push the water back into the tank, and the resistance changes are monitored in real time during the process to observe whether there is any jamming or poor lubrication.

Result analysis and cleaning

After the test is completed, the device automatically generates a report displaying key indicators such as average sliding force. Users can view data and export it as charts for analysis. Clean the equipment and turn off the power after the test is completed.
