Abstract
A catheter insertion device (10) includes a housing (12) with a base (14), a catheter (28), an introducer needle (30) and an actuator (26) mounted within the housing. The catheter (28) and needle (30) are coupled to the actuator (26) and movable between a first position where the catheter and needle are retracted within the housing and a second position where the catheter (28) and needle (30) extend from the housing, and where the needle retracts into the actuator when the catheter and needle reach the second position. A spring (90) is provided in the housing (12) or the actuator (26) where the spring (90) is released after deployment of the device to retract the needle (20) with respect to the catheter (28).
Claims20
A catheter insertion device comprising:
- a housing;
- a catheter having a catheter hub;
- an introducer needle within said catheter;
- a spring disposed in said housing;
- a spring retainer retaining said spring in a compressed state between a surface of said housing and said spring retainer;
- and
- an actuator having an end engaging said catheter hub, said actuator being movable from a first position where said catheter and introducer needle are positioned within said housing, and an extended second position where said catheter and introducer needle extend from said housing, and where said catheter hub engages said spring retainer when said actuator is in said extended second position to release said spring to engage said introducer needle and retract said introducer needle into said actuator.
A catheter insertion device comprising:
- a housing;
- an actuator having an axially extending slot, said actuator being movable with respect to said housing;
- a catheter and catheter hub coupled to said actuator;
- an introducer needle in said catheter and received in said slot of said actuator, said introducer needle connected to a fluid supply to supply fluid to said catheter when said introducer needle is in said retracted position;
- a spring;
- and
- a spring retainer to retain said spring in a compressed state;
- said actuator being movable from a first position where said catheter and introducer needle are positioned in said housing and a second position where said catheter and introducer needle extend from said housing, said actuator being configured to release said spring from said spring retainer when said actuator is moved to said second position to expand said spring, where said spring engages said introducer needle and retracts said introducer needle into said actuator and said slot when said actuator is moved to said second position.
A catheter insertion device comprising:
- a housing;
- a catheter and catheter hub;
- an introducer needle within said catheter, said introducer needle having a connecting portion connected to a fluid supply;
- a spring disposed in said housing;
- a spring retainer in said housing and retaining said spring in a compressed state between said housing and said spring retainer;
- and
- an actuator movable with respect to said housing, said actuator engaging said catheter hub, said connecting portion of said introducer needle extending from said actuator and being slidably received in said actuator, said actuator being movable from a first position where said catheter and introducer needle are in said housing and a second position where said catheter and introducer needle extend from said housing and said spring retainer releases said spring to retract said introducer needle into said actuator.
