Background

The diabetic patient needs to continuously inject insulin to treat, and the needle hole is constantly and repeatedly pricked on the skin surface, the infusion part is placed on the body of the patient for a long non-specific time period, and the infusion part can be connected and disconnected from time to time. This is overly cumbersome and frequent for the patient to be able to disconnect from the medical device, e.g. a pump connected to the drug reservoir, walk around, and reconnect to the medical device at some later point.

In addition, containers or gauges of different medications are also different, and different infusion components are converted between different medical devices (e.g., different medication reservoirs), requiring multiple skin penetration operations, which can cause discomfort to the patient.

Some people have a countering or hesitant mind to use medical needles to penetrate their own skin and experience difficulty in properly positioning the needle or cannula for proper administration.

For this reason, there is a need to address how to avoid frequent needle sticks of different medical devices to the skin surface.
