Abstract
(EN) A gas-liquid delivery connector, a gas-liquid delivery connector pair, and a gas-liquid delivery device. The gas-liquid delivery connector comprises: a male connector (1) for connecting a catheter, wherein the male connector (1) is provided with a first connecting channel (11) in the axial direction thereof; and a female connector (2) for connecting a microcatheter, wherein the female connector (2) is provided with a second connecting channel (21) in the axial direction thereof. The female connector (2) is connected to the male connector (1) such that the second connecting channel (21) is in butt joint with and in communication with the first connecting channel (11), and the inner diameter of the second connecting channel (21) is the same as the inner diameter of the first connecting channel (11). When a gas-liquid mixture flows from the first channel of the male connector to the second channel of the female connector, no large bubbles are generated, such that the smoothness of flow of the gas-liquid mixture is ensured, and embolism is prevented from occurring.
(FR) Raccord de distribution de gaz-liquide, paire de raccords de distribution de gaz-liquide, et dispositif de distribution de gaz-liquide. Le raccord de distribution de gaz-liquide comprend : un raccord mâle (1) pour raccorder un cathéter, le raccord mâle (1) étant pourvu d'un premier canal de raccordement (11) dans sa direction axiale ; et un raccord femelle (2) pour raccorder un microcathéter, le raccord femelle (2) étant pourvu d'un second canal de raccordement (21) dans sa direction axiale. Le raccord femelle (2) est raccordé au raccord mâle (1) de telle sorte que le second canal de raccordement (21) est en aboutement avec le premier canal de raccordement (11) et en communication avec ce dernier, et le diamètre interne du second canal de raccordement (21) est identique au diamètre interne du premier canal de raccordement (11). Lorsqu'un mélange gaz-liquide s'écoule du premier canal du raccord mâle au second canal du raccord femelle, aucune bulle importante n'est générée, de telle sorte que la régularité de l'écoulement du mélange gaz-liquide est assurée, et qu'une embolie est empêchée.
(ZH) 一种气液输送接头、气液输送接头对及气液输送装置。气液输送接头包括:用于连接导管的公接头(1),公接头(1)沿其轴向方向开设有第一连接通道(11);用于连接微导管的母接头(2),母接头(2)沿其轴向方向开设有第二连接通道(21);母接头(2)与公接头(1)连接,以使第二连接通道(21)与第一连接通道(11)相互对接并连通,且第二连接通道(21)的内径与第一连接通道(11)的内径相同。当气液混合物从公接头的第一通道流入母接头的第二通道时,不会出现大气泡,保证了气液混合物流动的顺畅性,防止出现栓塞。
