WO 2015154301 A1
Resumen
A medical switch connector for use in liquid diversion, convergence, injection, drawing, and drainage in medical procedures. Infusion connectors (4) of the medical switch connector are sealedly connected to a corresponding part of a connector base (1) in a way that allows movements relative to the connector base (1). A valve that opens or closes with movements of the infusion connectors (4) relative to the connector base (1) is bridged between an infusion channel (4.1) of the inner core of the infusion connectors (4) and a solution-transferring cavity (1.3) of the inner core of the connector base (1). The infusion channels (4.1) are in communication with a solution-outlet channel (1.2) of the inner core of a solution-outlet connector via the valve and the solution-transferring cavity (1.3). Based on such structure, when a penetrating needle is withdrawn at the completion of an infusion, no negative pressure is generated and a medicinal solution injection channel can be closed off, thus allowing for intermittent infusion. The three-way connector can be used in a swapped direction, that is, the solution-outlet connector is used as the infusion connectors (4), while the infusion connectors (4) are used as the solution-outlet connector; this is applicable in a scenario of medicinal solution diversion, that is, one extremity is used for solution supply, while multiple extremities are used for solution output.
