Syringe Tester GB15810-2019

Syringe tester is a professional testing instrument for identifying the physical properties of syringes.
The syringes mentioned here are also exquisite
.

Syringe is a general term for all types of syringes.
The types of syringes can be roughly divided into the following: insulin syringes, glass syringes, syringes with needles, syringes with power-driven syringe pumps, self-destructing fixed-dose vaccine syringes, and anti-reuse syringes , Syringes prefilled with medicinal liquid by the manufacturer and syringes matched with medicinal liquid,
etc.

The syringe we often say refers to a manual syringe used for sucking liquid or injecting immediately after sucking liquid, also known as a single-use sterile syringe
.

What Weixia Technology wants to talk to you about today is the one-time use of sterile syringes
.

The standard basis for single-use sterile syringes is GB15810-2019 single-use sterile syringes
.

The nominal capacity of the disposable sterile syringe is the syringe capacity marked by the manufacturer according to the standard, which can be roughly divided into 1ml, 5ml, 50ml and other specifications
.

In order to ensure the quality of single-use sterile syringes, GB15810-2019 single-use sterile syringe standards have made requirements for sterile syringes in terms of physical properties, chemical properties, biological properties, packaging, standards, and storage
.

Next, let's take a look at the physical requirements in detail
.

1.
Residual capacity Syringe residual capacity tester test principle: with the same syringe, the difference between the quality of the syringe before suction and after emptying, calculate the residual capacity of the syringe
.

According to the test method required by the GB15810-2019 standard for single-use sterile syringes, when the piston is completely pushed to the bottom of the jacket, the maximum residual capacity of the syringe should meet the requirements in Table 1
.

2.
The body tightness of the syringe body tightness positive pressure tester test principle: use a syringe to suck water, seal the cone hole of the syringe, the core rod is located in the most unfavorable direction relative to the jacket, and a certain force is applied to try to cause the piston and seal leaks
.

According to the test method for leakage at the piston or sealing ring when the syringe is under positive pressure, there should be no liquid leakage at the piston or sealing ring
.

The test principle of the negative pressure tester for the tightness of the syringe body: connect the cone head of the syringe to the equipment, and suction part of the water in the syringe.
Apply negative pressure through the cone head, check the leakage at the syringe piston and the sealing ring, and determine the piston Whether it has been separated from the core rod
.

According to the test method for the leakage of the piston or the sealing ring and the separation of the piston and the core rod when the syringe is pumping negative pressure, there should be no gas leakage at the piston or the sealing ring, and the reading of the pressure gauge should not continue to drop
.

3.
Sliding performance Syringe slidability tester test principle: The mechanical test device is used to discharge water from the syringe while continuously recording the force generated by the movement of the piston assembly
.

According to the sliding performance test method, the sliding performance value shall meet the requirements of Table 2
.

To sum up, the syringe tester includes a syringe residual tester, a syringe sliding tester, a syringe tightness positive pressure tester, a syringe tightness negative pressure tester and a 6% Luer cone joint multifunctional tester
