Definitions

  • the medical staff In use, after successful puncture of the flexible catheter with a puncture steel needle, the medical staff is required to apply pressure on the skin directly above the puncture vessel to close the blood vessel, and then quickly withdraw the puncture steel needle, insert the infusion closure joint, and compress the blood vessel to minimize The blood continues to escape outward through the steel needle and the catheter as it exits the puncture needle.
  • the above-mentioned techniques have the following disadvantages: First, the operation of the acupressure method is slightly inappropriate, and the blood outflow cannot be avoided, thereby causing blood pollution and causing safety hazards to medical personnel; secondly, the operation process of the indwelling needle is cumbersome. It requires skilled skills and rich experience, which will cause greater psychological pressure on medical staff and patients.
  • the gap of the seal needs to have a certain length, which is slightly larger than the radius of the upper sealing piece, so that the intermediate sealing section needs to provide a structure to cooperate with the slit, and the intermediate sealing section needs
  • flat structure is the best choice, can be flat, or flat oval.
  • Figure 6 is a schematic view showing the structure of another sealing angle of the sealing base in the sealed needleless joint of the present invention.

Abstract

La présente invention concerne un ensemble cathéter anti-reflux pour une aiguille à demeure qui comprend un cathéter flexible (1), une embase de cathéter (2) connectée à une extrémité du cathéter (1), et un adaptateur d'étanchéité sans aiguille (3). L'adaptateur d'étanchéité sans aiguille (3) comprend une base d'étanchéité (32) et un élément d'étanchéité (31). Une extrémité de la base d'étanchéité (32) est installée au niveau de l'extrémité extérieure de l'embase de cathéter (2). L'élément d'étanchéité (31) est un composant élastique souple, et entièrement constitué d'une feuille d'étanchéité supérieure (311), d'une feuille d'étanchéité inférieure (313) et d'une section d'étanchéité intermédiaire (312). Une fente de fermeture (314) disposée au centre est fournie sur la face terminale de la feuille d'étanchéité supérieure (311). La fente (314) passe de la feuille d'étanchéité supérieure (311), à travers la section d'étanchéité intermédiaire (312), et dans la feuille d'étanchéité inférieure (313). La longueur de la fente (314) est supérieure au rayon de la feuille d'étanchéité supérieure (311). La base d'étanchéité (32) a une cavité interne cylindrique allant de la gauche à la droite, dans laquelle l'élément d'étanchéité (311) est installé. La feuille d'étanchéité supérieure (311) et la feuille d'étanchéité inférieure (313) sont hermétiquement fixées sur les deux faces d'extrémité longitudinales de la cavité interne de la base d'étanchéité (32) respectivement, et un espace redondant se trouve entre la section d'étanchéité intermédiaire (312) et la cavité intérieure cylindrique. L'adaptateur sans aiguille a, dans son ensemble, une structure simple et une petite quantité de composants, il est ainsi peu coûteux.
