Abstract

La présente invention est une seringue qui peut être verrouillée dans un état de pression négative (vide), qui s'inscrit dans les domaines des nécessités humaines. Il s'agit également d'une sous-section du domaine de santé. L'objet de la présente invention est de produire une seringue ayant la capacité d'être verrouillée en mode d'aspiration (pression négative). Le changement d'état de la seringue d'un état de verrouillage à un état de déverrouillage et vice versa doit également être effectué facilement et avec une erreur minimale possible, et un plongeur en état verrouillé doit être aussi stable. De plus, la possibilité d'obtenir un déverrouillage ne doit pas se produire au niveau du plongeur. La présente invention est appliquée dans divers domaines, tels que l'aspiration du sang et d'autres fluides du corps humain à partir de la cavité thoracique et abdominale, l'aspiration de pus et de fluides à partir de kystes et d'autres lésions du corps humain, et la péricardiocentèse et l'aspiration du liquide articulaire.
