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; and

means for rotating said catheter assembly as said catheter assembly is advanced toward said extended position.

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 includes 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 housing cooperate to rotate said 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.

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; and

means for rotating said catheter assembly as said catheter assembly is advanced toward said extended position.

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

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

13. 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.

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

15. An IV catheter delivery device comprising:

a cylindrical housing with a housing front end, a housing rear end and a cylindrical housing extending therebetween;

a catheter assembly disposed in said housing and including a catheter member with a catheter front end adapted to be inserted in the vein of a patient;

a control member adapted to selectively move said catheter assembly from a retracted position wherein said catheter front end is disposed completely within said cylindrical housing and an extended position wherein said catheter front end extends outwardly of said housing front end;

biasing means for biasing said catheter assembly toward said retracted position; and

means for rotating said catheter assembly as said catheter assembly is advanced toward said extended position.

16. The device of claim 15 further comprising a needle member having a needle adapted to be inserted into a vein, said catheter member being telescopically mounted on said needle.

17. The device of claim 15 wherein said catheter front end is flexible.

18. 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 cylindrical housing.
