Embodiment Construction
[0056] Such as figure 1 , 2 , 10, and 11, the safety puncture needle of the present invention includes: a needle base 1, a needle body 2, an inner cylinder 3, an outer cylinder 4 and an elastic member 5. The safe puncture needle of the present invention and the indwelling soft needle 7 constitute the indwelling needle. Before using the safe puncture needle, the indwelling soft needle 7 is set on the needle body 2 of the safety puncture needle of the present invention, and the outside of the indwelling soft needle 7 is generally There will also be a protective cover 8, such as Figure 10 shown.
[0057] Such as image 3 As shown, the outer wall of the needle hub 1 is provided with a needle hub protrusion 13. In this embodiment, the needle hub 1 includes a columnar portion 11 and a cylindrical portion 12, and one end of the columnar portion 11 is fixedly connected to one end of the cylindrical portion 12. Together, the rear end of the cylindrical portion 12 is connected with...

The invention discloses a safety puncture needle, which comprises a needle seat, a needle body, an inner cylinder, an outer cylinder and an elastic member. Before the safe puncture needle of the present invention enters the safe state, the needle body protrudes from one end of the outer cylinder. After the puncture is completed, the inner cylinder is rotated to make the needle holder enter the inner cylinder, and the inner cylinder and the needle holder slide from one end of the outer cylinder to the The action of the other end makes the needle point enter the outer cylinder, so as to prevent the used puncture needle from hurting people, and the operation is simple and convenient. If sufficient force is not intentionally applied, the needle hub and inner barrel will not return to their original positions, so its safety is more reliable. The invention overcomes the disadvantage that the existing used puncture needles are easy to injure people, and provides a safe puncture needle which can prevent the used puncture needles from injuring people.
Description
technical field [0001] The invention relates to a medical transfusion device. Specifically, it is a safety puncture needle. Background technique [0002] At present, human transfusion has been widely used as an important and effective medical method for treating diseases. When the human body is transfused, the needle made of metal will cause pain to the patient when it is penetrated into the blood vessel of the human body. Multiple punctures are required if the disease requires multiple infusions. The indwelling needle can solve the above problems. The indwelling needle generally includes a puncture component and an infusion component. After the puncture is completed, the puncture component is separated from the human body. A part of the soft infusion needle of the infusion assembly is left in the blood vessel of the human body, and when infusion is performed next time, the infusion needle and the infusion tube can be connected for infusion without further puncture.
