Problems solved by technology

[0003] The purpose of the present invention is to provide an adjustable blood drawing auxiliary bracket, which can fix the patient's arm and relieve the patient's muscle tension, which facilitates the doctor to insert the needle to draw blood, alleviates the patient's fear of blood drawing, and increases the need for the patient to draw blood. The smoothness of the blood process reduces the chance of accidental injury caused by the patient's movement, and it is convenient to adjust the length and height of the bracket, which is suitable for different arm sizes. The state of restlessness and muscle tension makes it impossible for the doctor to draw blood, which will cause the blood drawing needle to be inserted in the wrong position, increase the patient's fear of drawing blood, and make it impossible to complete the blood drawing process. At the same time, it will also increase the risk of accidental injury As a result, the blood pumping auxiliary stent does not have the ability to adjust according to the state of the patient's arm, and the problem of low applicability
