Body-Fluid-And-Medication Leak-Proof and Closed Medical Connector

A body-fluid-and-medication leak-proof and closed medical connector, one of two ends of the body-fluid-and-medication leak-proof and closed medical connector detachably connected to an injector or a fluid infusion tube, the other of the two ends of the body-fluid-and-medication leak-proof and closed medical connector detachably connected to a vial or a catheter, thereby communicating between the injector and the vial, or communicating between the fluid infusion tube and the catheter;

• the body-fluid-and-medication leak-proof and closed medical connector comprising:
• a first connecting assembly detachably connected to the injector or the fluid infusion tube, communicating with the injector or the fluid infusion tube, and comprising
• a first sleeve having
• a first end detachably connected to the injector or the fluid infusion tube;
• a second end;
• and
• a first channel formed through the first sleeve, extending from the first end of the first sleeve to the second end of the first sleeve, communicating with the injector or the fluid infusion tube, and forming a first opening in the second end of the first sleeve;
• and
• a first resilient valve mounted in the first channel and selectively sealing the first opening;
• and
• a second connecting assembly detachably connected to the vial or the catheter, communicating with the vial or the catheter, detachably connected to the first connecting assembly, and comprising
• a second sleeve having
• a first end detachably connected to the vial or the catheter;
• a second end detachably connected to the second end of the first sleeve;
• and
• a second channel formed through the second sleeve, extending from the first end of the second sleeve to the second end of the second sleeve, communicating with the vial or the catheter, and forming a second opening in the second end of the second sleeve;
• a connecting portion mounted in the second channel and having
• a closed end;
• and
• at least one lateral hole formed through a side wall of the connecting portion, communicating with an inner space of the connecting portion, and disposed adjacent to the closed end of the connecting portion;
• and
• a second resilient valve mounted in the second channel, and selectively sealing the second opening;
• wherein when the first connecting assembly and the second connecting assembly are connected to each other, the first sleeve abuts the second resilient valve to move the second resilient valve relative to the connecting portion to expose the at least one lateral hole of the connecting portion out of the second resilient valve;
• simultaneously, the closed end of the connecting portion abuts the first resilient valve to open the first opening such that the first connecting assembly and the second connecting assembly communicate with each other.
