  • the dilution chamber 21 is not in communication with the flow guiding hole 53 of the drip member 5; when the drip member 5 is in the drip state, the spring 7 is compressed, and a gap is formed between the sealing cover 52 and the bottom surface 26 of the dilution chamber, and the dilution chamber 21 is formed.
  • the liquid flows into the flow guiding passage 54 through the flow guiding hole 53.
  • an exhaust groove 14 is provided on the outer wall of the liquid storage pipe, and an exhaust groove 29 is provided in the first annular side wall 27 of the dilution pipe 2.

Abstract

L'invention concerne un dispositif de retenue de fluide corporel scellé jetable, qui comprend un tuyau de stockage de fluide (1) et un tuyau de dilution (2). Le tuyau de stockage de fluide comprend une cavité de stockage de fluide (11) et une partie ouverture (12). Le tuyau de dilution comprend une cavité de dilution (21). La partie ouverture est munie d'un bloc (4). La partie ouverture du tuyau de stockage de fluide est située dans la cavité de dilution. Le dispositif est pratique à utiliser, avec lequel un échantillon peut être directement dilué dans une solution après échantillonnage, la charge de travail d'un expert est réduite, et la force de travail est diminuée ; une pollution secondaire de l'échantillon est empêchée efficacement ; et la diffusion d'odeur de l'échantillon est empêchée.
