Because the goal of the procedure is to place a plastic catheter into the vein. If you insert the needle/catheter vertically you will go through the vein. If you angle on insertion once placement in the vein is confirmed you can slide the hollow catheter off of the needle into the vein. The veins used for most IV's normally lie just under the skin. For this reason a shallow angle of insertion is used.
The optimal angle of insertion for a needle during a venipuncture is typically between 15 to 30 degrees relative to the skin surface. This angle helps to effectively access the vein while minimizing the risk of damaging surrounding tissues. A shallower angle may risk missing the vein, while a steeper angle could increase discomfort and complicate the procedure. Proper technique and positioning are crucial for successful venipuncture.
Healthcare professionals can prevent a hematoma when drawing blood by applying gentle pressure to the puncture site after removing the needle, ensuring proper needle insertion angle and depth, and avoiding excessive probing or movement of the needle during the procedure.
angle of pull is the angle between muscle insertion and the bone on which the muscle inserts
The angle of insertion for a subcutaneous injection is typically 45 to 90 degrees, depending on the thickness of the patient's skin and subcutaneous tissue. For thinner individuals, a 45-degree angle may be more appropriate, while a 90-degree angle can be used for those with more subcutaneous fat. It's important to ensure that the needle is inserted into the subcutaneous tissue to avoid intramuscular injection. Always follow specific guidelines or protocols for the best practice in your setting.
The needle should form a 15 to 30 degree angle with the surface of the arm.

A radial tire is different from a normal tire in that a radial tires athatre built to last longer. The main difference is that radial tire have wires or cords that radiate at a 90-degree angle from the tire rim.
