Angioket 18, 20 and 22 is a multipurpose medical device that is used for frequent and long-term injections of various solutions and drugs into the patient’s vein. This product prevents the flow of injected liquid back. One of the main features of the green angioket is the possibility of taking blood easily and quickly from the patient. Patients who are in poor condition and need continuous injection in a short period of time will be relieved from the difficulty of finding a vein by installing it once. The green angioket needle is made of stainless steel and is completely sterile, non-toxic and non-pyrogenic. Angioket is removed from the vein after the end of the treatment period, and usually every 72 hours, the previous needle must be removed and a new needle replaced.
