Definitions

  • the blood sampling technique is now quite mature, but it does not reach the goal of not collecting blood from the patient, or the initial process of the test is performed by the blood collection needle and the blood collection tube. Therefore, the blood collection needle is currently the largest in the world.
  • One of the medical device products are worth noting that millions of people occur every year in hospitals around the world due to needle breakage or improper handling of medical personnel. Statistics published by the American Medical Association show that only about 1 million health care workers in the United States are accidentally injured by blood-collecting needles each year. At least a thousand of them are infected with hepatitis B virus, hepatitis C virus and HIV attached to the needle. The cost of first aid treatment for each medical staff and patient who is injured by a broken needle is $3,000 per person.
  • the needle is retracted into a protective sleeve for protecting the needle by using a spring force such as a spring.
  • a spring force such as a spring
  • the sliding member is a cylindrical shape with two ends open and is sleeved on the needle seat, and the length of the sliding member in the moving direction is greater than the length of the needle;
  • the limiting mechanism is disposed on the slider and the needle seat, and is configured to fix the slider to the needle seat after the sliding member slides to completely shield the needle;
  • the sliding member is provided with a protective cover for protecting the limiting mechanism
  • the blood collection needle of the present invention has a needle holder longer than the needle, so that the above-mentioned cylindrical shape
  • the slider can then slide back and forth over the hub such that the needle switches between being obscured by the slider and fully exposed.
  • the limit mechanism is used to limit the movement of the slider.
  • the sliding member In use, in the initial state, the sliding member is fixed to the needle seat through the limiting mechanism, (ie, the needle is completely exposed), the needle sleeve is first removed, and blood is collected; after the blood collection is completed, the fixing of the sliding member and the needle holder is released, The slider slides in the direction of the needle until the slider completely shields the needle, and the slider is once again fixed to the needle holder (through the limit mechanism). In this way, since the needle sleeve can be shielded by wearing the needle sleeve, the safety is greatly improved.
  • the limiting mechanism includes a first elastic washer and two second elastic washers; the first elastic washer is attached to an inner circumference of the sliding member away from the end of the needle, and The edge of the first elastic gasket is smoothly fitted to the inner wall of the sliding member;

Abstract

L'invention concerne une aiguille de prélèvement sanguin sans danger, comprenant une base d'aiguille (2), un manchon d'aiguille (5), une tête d'aiguille (6), une pièce coulissante (1), une poignée (7) et des mécanismes limiteurs. La base d'aiguille (2) est cylindrique. Une extrémité de la base d'aiguille (2) est fixe et en communication avec la tête d'aiguille (6), et l'autre extrémité est pourvue d'un orifice raccordé à un tuyau de transport externe. La pièce coulissante (1) a une forme analogue à celle d'un cylindre, avec deux extrémités ouvertes, et est disposée avec possibilité de déplacement sur la base d'aiguille (2) en mode avec manchon. La longueur de la pièce coulissante (1) dans la direction du déplacement est plus grande que celle de la tête d'aiguille (6). La longueur de la base d'aiguille (2) dans la direction axiale est plus grande que celle de la tête d'aiguille (6). Les mécanismes limiteurs sont disposés sur la pièce coulissante (1) et sur la base d'aiguille (2). La poignée (7) est contiguë à la base d'aiguille (2) et est fixée à la pièce coulissante (1). La pièce coulissante (1) est pourvue d'un couvercle protecteur (4). La pièce coulissante (1) et le couvercle protecteur (4) sont fixes. Une pièce d'articulation entre le couvercle protecteur (4) et la pièce coulissante (1) est lisse. L'aiguille de prélèvement sanguin évite l'utilisation d'une tête d'aiguille à ressort et est en outre pourvue du couvercle protecteur (4) pour protéger la pièce coulissante (1), et pour une articulation lisse avec la pièce coulissante (1), ce qui soulage la douleur des patients.
