The penetration force, which occurs when the tip of the hypodermic needle inserts into the skin, is directly related to the pain felt by a person. It is said that the less penetration force, the less pain. Therefore, the penetration force is an important factor for hypodermic needle quality control and R&D. This video shows how to perform the peak penetration force and average Drag force test of a hypodermic needle complying with ISO 7864: 2016. The testing speed and needle penetration depth which specified in the standard can be easily set with Imada's measuring instruments. In addition, the peak penetration force and average Drag force results required by the standard, can also be displayed and calculated automatically by using Imada's force-displacement graphing software. It is useful for hypodermic needle's quality control and R&D.

In this video, the maximum force when pulling out the needle tube from the hub will be measured. This test complies with the corresponding part of ISO 7864: 2016. The non-destructive test that the needle tube keeps being pulled at certain force value can be also implemented with the same test unit. MED-NPT-200N, the attachment used in this video, has three slits with different widths and is available for needles whose diameters are from 0.3mm to 2.0mm. This kind of tests are conducted for quality evaluation, quality management, and R&D.

Syringe plunger is compressed to measure the compression (resistance) force for quality control and R&D.

Needle is fixed by specialized attachment to evaluate the force of pulling out the needle apart from the hub for quality control and R&D. It enables testing according to the corresponding part of ISO and JIS standard.

Syringe plunger is compressed to measure the compression (resistance) force for quality control and R&D. It complies with corresponding part of ISO 7886-1:2017.

Syringe needle is penetrated into something to measure its resistance force for quality control and R&D.

Medical devices and pharmaceuticals are used for diagnosis, treatment, and prevention of human and animal diseases, which are closely related to human and animal health. Therefore, high level of safety is required and many of these elements are strictly controlled by standards and internal regulations. This video shows how to perform a penetrability test of vial stoppers complying with ISO 8871-5: 2016. IMADA's specialized attachments, jig to fix the vial, Male Lure Slip Adapter to attach a hypodermic needle with 0.8 mm outer diameter (specified in the ISO standard), are used for this test. The peak force required for penetrating the vial stopper (rubber closure) is measured. The optional graphing software shows the entire force transition until the vial stopper (rubber closure) is penetrated, which helps you analyze the suitability of the vial stopper (rubber closure). It is used for the quality evaluation and quality control of vial.

To determine the strength and sharpness of acupuncture needle in conformance with the corresponding part of ISO 17218 : 2014, IMADA offers a dedicated testing system as the following configuration.

To determine the opening strength of a medical collection kit’s cap, grip the cap with a dedicated grip, and pull the cap with a force gauge. IMADA offers the dedicated testing system such as the following configuration, which is utilized in quality control and R&D.

Grip/pinch the forceps to the specialized attachment to measure gripping/pinch force for human gripping force training.

Medical devices and pharmaceuticals are used for diagnosis, treatment, and prevention of human and animal diseases, which are closely related to human and animal health. Therefore, high level of safety is required and many of these elements are strictly controlled by standards and internal regulations. This video shows how to measure the seal strength of flexible barrier materials complying with the corresponding part of ASTM F88/F88M-15: 2015. Using the optional graphing software, the user can graph the relationship between load and displacement at the same time as the measurement, and can also easily evaluate the seal strength while meeting the requirements of the standard (range selection of the center 80% of the acquired graph, obtaining average values from statistics).

This is compression test for measuring the hardness of tablets (pharmaceutical tablets). In this video, a tablet is pushed until it breaks using IMADA force gauge and a flat attachment. This test determines the hardness of tablets by obtaining the maximum load value when fracture initiates. Watch the video for more details. Tablet hardness testing is used for R&D and quality control.

This is probe tack test of adhesive plaster (bandage) to measure its adhesive strength for quality control and R&D.
