1. Explanation of Why Bleeding May Occur

During wearing, the guide needle needs to penetrate the epidermis and dermis to apply the electrode into the interstitial fluid between tissues. Due to the high density of capillaries in this layer, if the needle happens to pierce a densely vascularized area during application, it may cause slight bleeding, which is considered a normal occurrence.

2. Suggestions for Users

Rest assured, there's no need to worry.

The reason for the bleeding is that our sensor detects the content data of interstitial fluid through an electrode applied under the skin. During the application of the electrode/soft needle under the skin, a needle is used for assistance. Occasionally, when the needle pierces the skin, it may come into contact with the capillaries beneath the skin, leading to bleeding.

This process is similar to when you use fingertip blood glucose test strips. Our human body naturally stops bleeding quickly. All you need to do is gently apply pressure and wipe it clean. That's it.

Generally, it won't affect your continued wearing. If there is any abnormality or great discomfort, it is recommended to remove the sensor in time. If serious, please seek medical treatment in time.
