Definitions

  • the syringe is a commonly used device. It generally includes a syringe, a piston, and. In order to prevent cross-infection, the more people use it, the less it is used. But the syringe used now is not a management concept, but its performance is not "
  • a safety ejector consists of,, seal, piston and cylinder at the front
  • 01243 99.6 provides a safety syringe with a number of outer seals in the front cylinder of the outer sleeve and a number of grooves in the axial direction of the front phase. It is not suitable for injection. After the injection, the outer sleeve has a piston and the performance does not move.
  • the wood to be solved is to overcome the shortage of wood
  • Injection means self-destruction.
  • the wooden solution used for this wood is to use a safety syringe, which includes a jacket,,,, piston, and a cylinder in front of the jacket
  • the installation is fixed in the front. It is specially matched with the piercing through the outer cylinder.
  • the piercing Viseu has a seal seal in the outer casing.
  • the front part of the piston is connected to the piston.
  • the front end will be fitted with the inner jacket of the outer jacket with dimensions on the outer circumference of the outer jacket.
  • the inner circumference of the outer jacket has a matching forest inner circumference.
  • the seal is installed in a curve in front of the groove in the front of the jacket and has a fit in the coaxial direction.
  • the shape of the front end of the piston is consistent with the shape of the seal.
  • This article has a cross-shaped direction.
  • the original position is the same as weak.
  • This push-up carbon has a front inner circumference with a radius.
  • the front of this casing is fitted with a tube, the casing has a sealed front end, and some can cooperate with the outer casing. After the injection is completed, the puncture is completed.
  • the used safety syringe includes a jacket, a human piston 4, 6 fixed in 2 and the same installed in the jacket 5 before the jacket 5 has a cylinder in front of the 5? Inside the jacket, complete the injection.
  • the composition is basically the same as the existing wood.
  • the front end of the piston 4 has a film 41 on the front side of the 6 61.
  • the part connected to the piston is empty 62.
  • Ben 2 has Lin 23 in front of the jacket and has a center hole in front of the cylinder 5.
  • 5 and 5 coats can also be connected to the outside 5 5 cylindrical? 52 front. As shown in, 4. Can effectively limit the fixation in the jacket, it can not move forward.
  • the upper phase has a matching positioning 63.
  • This 6 61 has a radius of 7 before the inner circumference has a phase. To the position of 6 radians 61
  • Assembly flexibility 65 restricts the position in the 6 jacket.
  • the injection uses its own elasticity to lift upwards or upwards. 65 When the restriction is lifted, normal injection can be used now.

Abstract

La seringue de sécurité jetable comprend un manchon externe, une aiguille (1), un siège d'aiguille (2), un piston (4) et une tige principale (6). La partie arrière du siège (2) adopte la forme d'un cône en pointe (21) présentant une protubérance annulaire (22) fixée dans le manchon externe (5) par une boucle extensible d'étanchéité (3). Une zone de membrane (41) recouvre la surface d'extrémité avant du piston (4). Une cavité (62) est ménagée dans la partie avant du cylindre (61) de la tige principale (6). A la fin de l'injection, la tige principale (6) pousse en avant le piston (4) et la boucle extensible d'étanchéité (3). La protubérance annulaire (22) sur la partie arrière du siège (2) s'engage solidement dans la cavité (62) sur la partie avant du cylindre (61) de la tige principale (6), ce qui permet le retrait du siège (2) dans le manchon externe (5). Une boucle de verrouillage (7) est placée sur la partie arrière du manchon externe (5). La boucle de verrouillage (7) présente une saillie de butée en cône (61) sur la paroi externe et une rainure de positionnement (76) sur la paroi interne. Une saillie de positionnement (73) en coopération avec la rainure de positionnement (76) est ménagée sur la tige principale (6).
