Embodiment Construction

[0048] Figure 1 to Figure 3 Shown is a medical stopcock 1 which allows the preparation of a mixture, preferably an emulsion, intended to be injected into a patient. The medical stopcock 1 comprises a hollow body 2 from which extend three female connectors 5a, 5b and 5c and one male connector 6, preferably a Luer connector. The body 2 comprises a central hole 200 from which extend four conduits 2a, 2b, 2c and 2d which extend through the connectors 5a, 5b, 5c and 6 respectively.

[0049] Plug valve 1 comprises plug 3, and this plug is specifically as Figure 4 and Figure 5 As shown, it is rotatably mounted in bore 200 . The plug 3 includes a fluid circulation channel 10 for communicating the conduits 2a, 2b, 2c and 2d in a manner as described below. The plug 3 comprises an outer cylindrical wall 14 for ensuring the tightness of the plug valve 1 to the hole 200 . The axial end of the plug 3 comprises a collar 16 held in the body 2 by clipping.

Abstract

A medical stopcock (1) comprising: a body (2) equipped with three female connectors (5a, 5b, 5c) and a male connector (6), the female connectors (5a, At least one (5c) of 5b, 5c) is designed to receive an infusion syringe; and a moving plug (3) mounted in the body (2), equipped with a rotating rod, and comprising a fluid loop channel. The female connector (5c) designed to receive an infusion syringe includes a safety self-locking device to prevent a mixing syringe from being mounted on this connector (5c). The invention also relates to a kit for preparing a product to be infused, said kit comprising such a medical stopcock (1). The invention also relates to a method for preparing a mixture or emulsion intended to be implanted in a patient with the help of such a medical stopcock (1).

Description

technical field [0001] The present invention relates to a medical stopcock, to a kit for preparing a product, preferably a mixture or an emulsion, to be injected, said kit comprising such a medical stopcock, and to a kit for preparing a product intended to be injected into a patient. A method of products or emulsions, said method being carried out with the help of such a preparation kit. Background technique [0002] Lipiodol has now been used in interventional radiology procedures for nearly three decades. is characterized by its tendency to be selectively captured by liver tumors. Therefore, this oil is used as a carrier of anticancer agents for the treatment of hepatocellular carcinoma technically known as arterial chemoembolization (TACE) (Nakamura et al.: Radiology, 1989; 170:783 -6 and J.M.Idée-B.Guiu: Critical Reviews in Oncology / Hematology, 2013;88(3):530-49 [Nakamura et al., Radiology, 1989;170:783-6 and J.M.Idée, B.Guiu: Oncology / Hematology Reviews, 2013;88(3):...
