ISO 11608-3 with cartridge loose and retention test

Test requirements

Compared with the traditional small bottle and syringes, for delivering drugs (such as insulin pen injector has gain professional recognition.Injection of optimization design is easy to use, at the same time of delivering small doses provides higher accuracy, and injection in patients with pain relief.In order to verify the new pen injector design and at the age of mass production to maintain consistent quality, need a large number of mechanical testing.

Mechanical test including measurement to medicine pen injector operation when the required thrust.It is called "loose and sustainability", ISO 11608-3 involved in the relevant test method for finished product container type needle injection systems.It is very important for patients, because if the patient underwent treatment requires frequent small dose injection, requires the use of pre-filled cartridge, and input dose into the skin.The larger thrust or violent games cause the pain of pricker.

The solution

BOB体育最新下载安装Mecmesin pen injector with leading multinational companies and pre-filled cartridge manufacturer cooperation, to provide easy to use and cost-effective test solutions.In order to implement the ISOBOB体育最新下载安装 11608-3 of the breaking strength and sustainable force test, Mecmesin MultiTest 2.5 -i test system is the ideal choice.It is controlled by the Emperor software, the operator can quickly and easily select test method, the sample fixed in custom fixture, finish the work by the tester.

Lever is connected to the tester sensor will automatically reduce, detected until the top of the cartridge plug and set to zero position.From starting to 50 mm/min on the travel distance of constant speed in 40 mm cartridge plunger applied axial load, and real-time display a strength/displacement data on the graph.

At the end of the test, it will automatically calculate the following key parameters:

Loose force (also known as the "breakthrough" or "initial force") required to start the piston movement is the first peak

, this article, including the average force to keep plunger movement, and the entire movement stage, the minimum/most strongly

Result shown in the chart table beside, and classify the acceptance criteria according to ISO 11608-3.The results automatically included in the test report or export to the network to include in the other analysis software.

The same device effortlessly for cartridge leak test, testers from the cartridge liquid medicine box under the condition of leakage, (based on the inner diameter of the cartridge case) at a predetermined force exerting force of 60 seconds.

Test equipment
