Abstract

A catheter appliance having a catheter in fluid communication with a luer connector is releasably secured to a catheter applicator having a track for slidably mounting a needle carrier module. The needle carrier module includes a hypodermic which extends through the catheter for insertion and which is in fluid communication with a flashback indicator on the module. The catheter applicator includes a needle cavity for containing the hypodermic needle after use.

Claims

1. A catheter and insertion device comprising:

(a) a catheter applicator having a catheter for insertion into the vein of a patient;

(b) a catheter appliance releasably secured to said catheter applicator; and

(c) a needle carrier module slidably mounted on said catheter applicator, said needle carrier having a hypodermic needle extending through said catheter.

2. The catheter and insertion device according to claim 1 wherein said catheter applicator comprises a paddle having a track down the center with a catheter retainer pawl at one end, a needle cavity at the opposite end and a rear track stop near the needle cavity end of said track.

3. The catheter and insertion device according to claim 1 wherein said catheter appliance comprises a catheter carrier body having a catheter flap, a paddle retainer for securing said catheter appliance to said catheter applicator and a luer connector mounted on said body and in fluid communication with said catheter.

4. The catheter and insertion device according to claim 3 wherein said luer connector is rotatably mounted on said body.

5. The catheter and insertion device according to claim 3 further comprising a one-way check valve between said catheter and said luer connector.

6. The catheter and insertion device according to claim 3 further comprising a two-way valve between said catheter and said luer connector.

7. The catheter and insertion device according to claim 1 wherein said needle carrier module comprises a needle carrier having a flashback cavity containing a flashback indicator, a hypodermic needle mounted on said needle carrier to extend through said catheter and in fluid communication with said flashback cavity, a track follower and a needle carrier retainer spring.

8. A catheter and insertion device comprising:

(a) a catheter applicator comprising a paddle having a track down the center with a catheter retainer pawl at one end, a needle cavity at the opposite end and a rear track stop near the needle cavity end of said track;

(b) a catheter appliance releasably secured to said catheter applicator comprising a catheter carrier body having a catheter flap, a paddle retainer for securing said catheter appliance to said catheter applicator and a luer connector mounted on said body and in fluid communication with said catheter; and

(c) a needle carrier module comprising a needle carrier having a flashback cavity containing a flashback indicator, a hypodermic needle mounted on said needle carrier to extend through said catheter and in fluid communication with said flashback cavity and a track follower slidably secured on said track by a needle carrier retainer spring.

9. The catheter and insertion device according to claim 8 wherein said luer connector is rotatably mounted on said body.

10. The catheter and insertion device according to claim 8 further comprising a one-way check valve between said catheter and said luer connector.

11. The catheter and insertion device according to claim 8 further comprising a two-way valve between said catheter and said luer connector.
