Description

Technical Field

[0001] The utility model relates to a screening machine for producing blood collection needles, belonging to the technical field of blood collection needle production. Background Art

[0002] The blood collection needle is composed of a needle and a needle rod. The needle is arranged at the head of the needle rod, and a sheath is slidably connected to the needle rod. A reset spring is arranged between the sheath and the needle rod, and the initial position of the sheath is located at the head of the needle and the needle rod. When the operator holds the needle tube and presses the head of the blood collection needle on the patient's limb, the sheath retracts under the elastic force of the skin, causing the needle to protrude and pierce the skin to cause minimal trauma. When the blood collection needle is removed, the sheath resets under the action of the reset spring to cover the needle to prevent the needle from being exposed and contaminated or accidentally stabbing the human body.
