NEEDLE WITH SEALING VALVE |
摘要 |
<p>A needle assembly (100) having a hollow needle (110) with a pointed distal end (112) and a proximal end (114). The assembly also includes a needle hub (120) having a distal hub end (122) fixedly connected to the needle (110), a proximal hub end (124) having an opening, and a passageway (126) extending therethrough between the distal end and the proximal end. A valve (140) is disposed within the passageway (126), wherein the valve comprises a sealing member (142) having at least one through-opening (150) disposed therein and a plunger (146) disposed proximate the sealing member (142) and slidable between a first position wherein the at least one through-opening (150) is closed such that the hollow needle (110) and the proximal hub end (124) are not in fluid communication with each other and a second position wherein the plunger (146) biases the at least one through-opening (150) to an open position, such that the hollow needle and the proximal hub end are in fluid communication with each other. A method of using the needle assembly (100) is also disclosed.</p> |
