This invention relates to the field of blood drawing nursing technology, specifically a blood drawing nursing device to reduce psychological resistance. It includes a partition with a display screen embedded inside. An airbag A is installed inside the partition, and an air pump is connected to one side of airbag A. A support plate is connected to one side of the partition, and a grip ring is fixedly connected to the upper end of the support plate. Guide grooves are installed on both sides of the support plate, and cooling plates slide inside both sets of guide grooves. An airbag B is fixedly connected to the outside of the grip ring. This invention generates continuous tactile stimulation by the reciprocating motion of the cooling plates on both sides of the arm. This physical stimulation, through nerve conduction, distracts the brain's attention, reducing the pain of needle insertion and lowering the patient's sensitivity to pain. Simultaneously, the partition and the display screen block the patient's direct line of sight to the needle and puncture site, preventing fainting and tension caused by visual stimulation, thus keeping the patient relaxed during the blood drawing process.
