Abstract

A device for delivering an IV catheter to an IV infusion site is disclosed. The device includes a cylindrical housing adapted to fit into the hand of the clinician. A catheter assembly is disposed in the housing and can be advanced to an extended position and retracted. The catheter assembly includes a needle adapted to be inserted into the vein and the catheter is mounted on the needle to allow the catheter to be removed at will. The catheter assembly is rotated as the needle is inserted into the vein. Preferably the catheter assembly is rotated during the insertion of the needle and catheter. After the needle and catheter are inserted into the vein, the needle is retracted into the housing leaving the catheter in place. The housing and the needle can now be discarded.

Claims

1. A device for establishing an IV catheter by a clinician comprising:

a housing sized and shaped to fit in the hand of the clinician;

a catheter assembly including a catheter member with a front portion adapted to be inserted into the vein of a patient;

a control member adapted to reciprocate said catheter assembly within said housing between a retracted position in which said catheter assembly is completely contained in said housing and an extended position in which said catheter member extends outwardly of said housing, said control member being movable with respect to said catheter assembly for selectively locking said catheter assembly with respect to said housing; and

rotating means adapted to rotate said catheter assembly about an axis as said catheter assembly is reciprocated by said control means.

2. The device of claim 1 wherein said catheter member is removably attached to said catheter assembly so that it can be removed in said extended position.

3. The device of claim 1 wherein said catheter assembly indudes a needle member including a needle which extends outwardly of said housing when said catheter member is in the extended position, said needle being arranged and constructed for insertion in the vein, said catheter member being telescopically associated with said needle member.

4. The device of claim 3 wherein said catheter member is removably attached to said needle member.

5. The device of claim 1 wherein said catheter member and said housing cooperate to rotate said catheter assembly about a longitudinal axis as said catheter assembly is reciprocated by said control member.

6. The device of claim 1 further comprising locking means for locking said catheter assembly with respect to said housing.

7. The device of claim 6 wherein said locking means is adapted to lock said catheter assembly in said retracted position.

8. The device of claim 6 wherein said locking means is adapted to lock said catheter assembly in said extended position.

9. The device of claim 1 further comprising disabling means adapted to selectively disable said catheter assembly within said housing to prevent said catheter assembly for being moved extend outside said housing.

16. The device of claim 1 wherein said housing and said control member cooperate to lock said catheter assembly in a retracted position in which said catheter is disposed within said housing.

17. The device of claim 1 wherein said housing and said control member cooperate to lock said catheter assembly in an extended position in which said catheter extends outwardly of said housing.

18. The device of claim 1 wherein said housing includes at least a hole and said control member is pivoting with respect to said housing and said catheter assembly between two positions, including a first position in which said control member engages said hole, and a second position that allows the catheter assembly to be reciprocated within said housing.

10. A device adapted to establish a catheter for providing IV infusions to a patient through a vein, said device comprising:

a cylindrical housing having a front end, a rear end and a cylindrical surface extending therebetween;

a catheter assembly including a needle member with a needle and a catheter member removably attached to said needle member and telescopically arranged on said needle;

control means for reciprocating said catheter assembly between a retracted position wherein said catheter assembly is completely disposed within said cylindrical and an extended position wherein said needle and said catheter member are operative to be inserted in the vein, said control means and said catheter assembly being rotatably joined to allow said catheter assembly to rotate with respect to said housing during said reciprocating; and

rotating means adapted to rotate said catheter assembly about an axis as said catheter assembly is reciprocated by said control means.

11. The device of claim 10 wherein said catheter assembly further comprises a piston, said needle member and said catheter member being connected to said piston.

12. The device of claim 10 further comprising a first locking means for locking said catheter assembly in said retracted position.

13. The device of claim 10 further comprising a second locking means for locking said catheter assembly in said extended position.

14. The device of claim 10 further comprising control disabling means adapted to disable said control means to prevent said catheter assembly from being moved to extend outside said cylindrical housing.

15. The device of claim 10 further comprising biasing means for biasing said catheter assembly toward said retracted position.

19. A device for establishing an IV catheter by a clinician comprising:

a housing sized and shaped to fit in the hand of the clinician;

a catheter assembly including a catheter member with a front portion adapted to be inserted into the vein of a patient;

a control member adapted to reciprocate said catheter assembly within said housing between a retracted position in which said catheter assembly is completely contained in said housing and an extended position in which said catheter member extends outwardly of said housing; and

control disabling means adapted to disable said control means to prevent said catheter assembly from being moved to extend outside said housing.

20. A device adapted to establish a catheter for providing IV infusions to a patient through a vein, said device comprising:

a cylindrical housing having a front end, a rear end and a cylindrical surface extending therebetween;

a catheter assembly including a needle member with a needle and a catheter member removably attached to said needle member and telescopically arranged on said needle;

control means for reciprocating said catheter assembly between a retracted position wherein said catheter assembly is completely disposed within said cylindrical and an extended position wherein said needle and said catheter member are operative to be inserted in the vein; and

control disabling means adapted to disable said control means to prevent said catheter assembly from being moved to extend outside said housing.

21. A device for establishing an IV catheter by a clinician comprising:

a housing sized and shaped to fit in the hand of the clinician;

a catheter assembly including a catheter member with a front portion adapted to be inserted into the vein of a patient;

a control member adapted to reciprocate said catheter assembly within said housing between a retracted position in which said catheter assembly is completely contained in said housing and an extended position in which said catheter member extends outwardly of said housing, said control member being movable with respect to said catheter assembly with respect to said catheter assembly for selectively locking said catheter assembly with respect to said housing; and

control disabling means adapted to disable said control means to prevent said catheter assembly from being moved to extend outside said housing.

22. A device adapted to establish a catheter for providing IV infusions to a patient through a vein, said device comprising:

a cylindrical housing having a front end, a rear end and a cylindrical surface extending therebetween;

a catheter assembly including a needle member with a needle and a catheter member removably attached to said needle member and telescopically arranged on said needle;

control means for reciprocating said catheter assembly between a retracted position wherein said catheter assembly is completely disposed within said cylindrical and an extended position wherein said needle and said catheter member are operative to be inserted in the vein, said control means and said catheter assembly being rotatably joined to allow said catheter assembly to rotate with respect to said housing during said reciprocating; and

control disabling means adapted to disable said control means to prevent said catheter assembly from being moved to extend outside said cylindrical housing.
