De-needle and liquid leakage detecting device combined with safety needle

The invention relates to a de-needle and liquid leakage detecting device, in particular to a de-needle and liquid leakage detecting device combined with a safety needle.

Long-term treatment of puncture of blood vessels from the body surface is a common clinical treatment, such as hemodialysis or central venous catheters. The needle after puncture needs to be fixed on the body surface for a period of time. At this time, the risk of leakage or infection accompanying the needle removal is low, but it is a fatal high risk! Especially for patients with inflammatory, cognitive impairment, occlusion or home dialysis, it is not to be ignored. Nowadays, it is only possible to rely on the nursing staff to check repeatedly, and it is rare to introduce such monitoring equipment; the American ANSI/AAMI more clearly stipulates that the dialysis machine needs to be filled with a warning that cannot detect the blood loss of the needle, reminding the medical staff to pay attention to this limitation.
