Description

Self-fixing disposable blood taking needle

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical equipment, in particular to the technical field of a self-fixing type disposable blood taking needle.

[ background of the invention ]

The venous blood taking needle generally comprises a head needle for puncturing a blood vessel, a tail needle for puncturing a vacuum blood taking test tube and a hose for connecting the head needle and the tail needle, and blood can be sucked into the tube by using negative pressure in the test tube to realize blood collection. According to the operating specification requirement of medical personnel, the medical adhesive plaster is used for fixing the blood taking needle in the blood taking process so as to avoid blood taking failure caused by the fact that the blood taking needle is separated or displaced, or the needle tip is rubbed and moved in the blood vessel cavity to damage the vein, thereby bringing pain to patients. However, since the medical tape is required to be placed in a dedicated container of a treatment tray or a treatment cart, when a medical worker draws blood, the medical worker holds the blood collection needle with one hand and cannot easily take out the medical tape from the treatment tray and smoothly tear the protective film to fix the blood collection needle with the other hand, so that compliance in fixing the blood collection needle with the medical tape is very poor, and the medical tape is usually fixed by simply pressing the blood collection needle with a hand.
