What instruments are there for infusion testers?

What is the basic structure of an infusion set? The basic structure of the infusion set is composed of a stopper piercer, a drip pot, a catheter, a regulator, and a connector; A typical stopper puncher consists of: bottle insertion needle, protective cap, air filter membrane; Drip pot: composed of dropper and drip bottle; Conduit: is a long, transparent hose, generally made of
PVC material.
Interface: sliding sleeve type and locking type, 6% taper; Locked-in interfaces are safer and more reliable
.
According to the different components of the infusion set, there is a professional infusion tester to check its physical properties, test the tightness of the infusion set, and test the flow rate of
the infusion set.
Infusion device tightness test instrument - YM-C medical device tightness tester YM-C medical device tightness tester test process: GB8368-2018 standard requires that the infusion set should have no gas leakage phenomenon during the test, before the test starts, the entire system is adjusted at the test temperature, the infusion device is connected to the gas source, and the air pressure above the atmospheric pressure of 50kPa is applied inside the other outlet for 15s
.
Test for infusion set air leaks
in 40°C water.
Fill the infusion set with distilled water to remove bubbles, connect it to a straight empty device, and apply a pressure of -20kPa internally for 15s at 40 °C to check whether air enters the infusion device
.
Of course, there are also infusion set leakage positive and negative pressure tester, infusion set leakage positive pressure tester, infusion set leakage negative pressure tester, to test the sealing performance
of the infusion device body.
Infusion set flow rate test instrument--YL-C medical device flow testerYL-C medical device flow tester test process: fill an infusion container with distilled water at (23+2) °C and close the cork
.
The intake device is inserted into the container through the bottle and then into the infusion set
.
Turn off the flow regulator
.
Adjust the height of the vessel so that it forms a 1 m static head throughout the test, adjust the flow regulator to the maximum, and measure the flow rate
of the water in the infusion set.
Remove the filter from the air intake and repeat this step
.
Infusion device interface performance test - ZZ1962-C Luer cone joint multi-function testerZZ1962-C Luer cone joint multi-function tester can test a variety of 6% taper, locking and non-locking Luer joints, inspection items up to ten items, including leakage, air leakage, separation force, unscrewing torque, easy assembly, slip wire resistance, overload resistance, stress cracking, pressure decay leakage, positive pressure liquid leakage, negative pressure air leakage and other performance
.
And during the test, the axial force, torque, holding time, internal water pressure, separation force, leakage rate values
applied by the assembly are displayed.
