Luer comprehensive performance tester CSI-Z001 Shanghai Chengsi operation guide

The Luer Comprehensive Performance Tester Luer is a standardized microvolume impermeable connector that connects with a matching female Luer section through a male Luer
.

Now widely used in medical and laboratory instruments
.

Luer fittings are convenient connection devices used in the medical industry, which greatly simplify the management of liquid and gaseous medical fluids
.

The luer connector can switch 4 infusion bags without inserting and removing the patient's infusion needle
.

The connector also allows multiple compatible fluids to be administered using the same line, reducing trauma to the patient
.

Luer comprehensive performance tester is used to test medical device (Luer) conical joints (locking and non-locking) for liquid leakage, air leakage, separation force, unscrewing torque, ease of assembly, slip resistance, stress cracking, positive A number of performance indicators such as pressure and negative pressure are one of the important means to identify Luer cones for medical devices
.

Technical parameters: Axial force: 1N~50N; Internal water pressure: 200kPa~400kPa; Separation force: 1N~50N, its rate is 10 N/s; Holding time: 1~60s can be set arbitrarily; Torque sensor: 0N.

M Syringe nominal capacity: 1mL~60mL optional
.

Functional test: 1.
Ease of assembly Install the joint to be tested on the outer or inner standard conical joint by hand
.

For joints in rigid materials, install the joints tightly; for joints in semi-rigid materials, apply a torque of no more than 0.
08 N"m while applying no more than 20 N of axial force
.

 2.
Stress crack the joint under test with a standard conical joint Connection, the connected joint should be dry
.

When assembling, apply an axial force of not less than 27.
5 N, hold for 5 seconds, and apply a torque of not less than 0.
12 N"m
.

The assembled joint is placed at 20℃±5℃ for 48h±1 3.
Unscrew torque Assemble according to the procedure specified in 5.

m N" m to the assembly for a duration of not less than 10s
.

Do not apply any force in other directions or apply any inertial load 4.
The separation force connects the joint under test with the standard conical joint.
Standard joint; Assemble with the assembly procedure for the leak test
.

Apply an axial force of 35 N gradually in the direction away from the test fixture at a rate of 10 N/s for a duration of not less than 10 s, not in other directions Apply any force or apply any inertial load on it
.

5.
Leakage will connect the joint under test with the standard joint, the size of the standard joint should be in accordance with Figure 5 or Figure 7, respectively
.

The connected joint should be dry
.

Apply no more than 27.
5 N during assembly of axial force while applying a torque of not more than
.
12N
"m to inject water and exhaust air into the assembly
.

Make sure the outside of the assembly is dry
.

Along the axis of the horizontal locking joint, seal the outlet of the assembly, apply the internal water pressure to 300 kPa to 330 kPa, and keep it for 30S
