Abstract

A catheter syringe conveyor with a needle guard housing is adapted to facilitate the insertion of a catheter into a targeted blood vessel. A catheter syringe is slidably situated within a hand-held housing structure; a syringe holder that is slidably connected to the housing allows a technician to maneuver the catheter syringe up and down within the housing. At least one stabilizer finger is attached to the bottom of the housing. After a blood vessel is penetrated by the needle of the catheter syringe, the technician maneuvers a catheter pusher to lower the catheter off of the needle and into the blood vessel. After the catheter is inserted, the technician is able to slide the catheter syringe back up within the housing to move the needle within the protective walls of the housing for safety, and a syringe lock holds it there securely for safekeeping.

Claims

a stabilizer comprising at least one stabilizer finger with a bottom surface that contacts said skin of said patient on one side of a targeted blood vessel during said catheter insertion procedure;

a syringe holder adapted to retain said blood receptacle component of said catheter syringe so that said catheter syringe can be maneuvered within said housing stably, said syringe holder comprising a body that is slidably connected to said housing so that said syringe holder can be maneuvered along said longitudinal axis of said housing, wherein part of said syringe holder is adapted to protrude from said housing slit for access by a technician; and

a catheter pusher adapted to contact said catheter hub, said catheter pusher further adapted to protrude from within said housing slot and allow said technician to urge said catheter down over said needle to separate said catheter from said syringe.

2. The device of claim 1 wherein said stabilizer comprises two stabilizer fingers, each stabilizer finger comprising a bottom surface that contacts said skin of said patient on opposite sides of said targeted blood vessel during said catheter insertion procedure, and said stabilizer fingers are connected to said bottom end of said housing so that said housing positions said needle of said syringe to enter into said blood vessel between said stabilizer fingers.

3. The device of claim 2 wherein said stabilizer fingers are spaced apart so as to contact said skin above said blood vessel directly adjacent said blood vessel, to stabilize said blood vessel as well as said housing during said catheter insertion procedure.

4. The device of claim 1 further comprising a stabilizer finger adjustment track in which each stabilizer finger is set, said stabilizer finger adjustment track adapted to allow said technician to adjust the position of each stabilizer finger.

5. The device of claim 3 wherein:

said bottom surface of each of said stabilizer fingers is elongated and positioned so that at least part of said bottom surface of each of said stabilizer fingers is angled relative to said longitudinal axis of said housing, said angle adapted to retain said syringe over an artery at a predetermined angle when said stabilizer is properly pressed onto the patient'"'"'s skin above said artery, thereby providing an appropriate and steady angle of needle passage into said artery; and

said housing positions said needle to enter said artery beyond the shortest tip of said stabilizer fingers.

6. The device of claim 1 wherein said housing comprises a first and a second housing slit, and part of said syringe holder protrudes from said first housing slit while part of said catheter pusher protrudes from said second housing slit for access by said technician.

7. The device of claim 1 wherein part of said syringe holder and part of said catheter pusher both protrude through said housing slit and are slidably situated there.

8. The device of claim 1 wherein, said syringe holder further comprises a syringe lock adapted to render said syringe immobile within said housing slot within at least one predetermined location where the tip of said needle is stationed within said housing near said bottom end of said housing.

9. The device of claim 1 further comprising a guide wire unit attached to said blood receptacle of said catheter syringe, said guide wire unit adapted to allow said technician to insert into said blood vessel a flexible feed over which said catheter can travel as said catheter is inserted into said blood vessel, wherein said housing comprises a top perimeter that frames an aperture at said top end of said housing, and said guide wire unit is adapted to emerge out from within said top perimeter at said top end of said housing.

10. The device of claim 8 wherein said syringe holder further comprises a syringe holder arm that is adapted to protrude from said housing slit for access by said technician.

11. The device of claim 10, further comprising a housing bridge that comprises a rigid structure joining at least part of each side of said housing slit, said housing bridge adapted to add structural support to said housing by closing at least part of the gap within said housing created by said housing slit, wherein said housing bridge is elevated compared to the rest of said housing to allow at least said syringe holder arm to pass within said housing bridge as said syringe holder is maneuvered within said housing.

12. The device of claim 10 wherein:

said syringe lock further comprises a locking tooth incorporated on said syringe holder arm, said locking tooth comprising a protuberance adapted to engage into a locking position along at least one section of said housing; and

said housing further comprises at least one notch cut within said housing, said notch adapted to receive and lock said locking tooth in place.

13. The device of claim 12 wherein:

said housing further comprises a series of notches cut into said housing along a linear path near said housing slit; and

said syringe holder arm further comprises a first end accessible to said technician and a second end where said locking tooth is disposed, whereby when said first end is released by said technician while said locking tooth is positioned within the boundaries of said series of notches, said locking tooth engages fixedly within one of the notches, and said locking tooth dislodges from within said notch when said technician appropriately presses on said first end, thereby freeing said syringe holder arm for movement up or down said housing, said series of notches adapted to provide multiple locations along the length of said housing to securely retain said syringe holder arm.

14. The device of claim 1 wherein said catheter pusher comprises:

a catheter pusher body shaped to slide stably up and down said housing; and

a push member attached to said catheter pusher body, said push member adapted to be situated between said blood receptacle and said catheter hub, said push member adapted to contact said catheter hub to allow said technician to push said catheter hub down over said needle.

15. The device of claim 14 wherein said catheter pusher further comprises a catheter pusher arm adapted to emanate from said catheter pusher body, said catheter pusher arm adapted to protrude out from within said housing for contact by said technician.
