Abstract

An insertion device is disclosed. The insertion device includes a base portion, a top portion slidably connected to the base portion, an introduction needle, a catheter in slidable relation to the introduction needle, and a substantially cylindrical flash chamber, the flash chamber having an inlet in fluid communication with the introduction needle. The flash chamber is connected to the base portion, the top portion slidably engages with the flash chamber, and the catheter and the top portion slidably advance with respect to the introduction needle and the base portion.

First claim

What is claimed is:

1. An insertion device comprising:
a base portion;
a top portion slidably connected to the base portion;
an introduction needle;
a catheter in slidable relation to the introduction needle;
a substantially cylindrical flash chamber, the flash chamber having an inlet in fluid communication with the introduction needle;
wherein the flash chamber is connected to the base portion, and
wherein the top portion slidably engages with the flash chamber, and
wherein when the top portion slidably advances towards the introduction needle the top portion maintains slidable engagement with the flash chamber while advancing;
a locking mechanism having a first end and a second end, the locking mechanism located on the base portion; and
a clip connected to the top portion, wherein the clip adapted to accommodate and control the locking mechanism and wherein the clip slidably engages the locking mechanism,
wherein as the top portion slidably advances with respect to the base portion, the clip slidably advances from the first end of the locking mechanism to the second end of the mechanism, whereby the locking mechanism moves from an unlocked to a locked position and whereby in the locked position, the top portion is positioned about the needle.

2. The insertion device of claim 1 , wherein the flash chamber further comprising an insert.

3. The insertion device of claim 2 , wherein the insert is a cylindrical insert.

4. The insertion device of claim 2 , wherein the insert comprising a color contrasting to the color of a flash fluid.

5. The insertion device of claim 2 , wherein the insert comprising a wicking material.

6. The insertion device of claim 5 , wherein the wicking material further comprising an assay test strip wherein the assay test strip indicates the presence of one or more indicators in a fluid.

7. The insertion device of claim 1 , wherein the flash chamber further comprising a filter.

8. The insertion device of claim 7 wherein the filter comprising a membrane material.

9. The insertion device of claim 1 , wherein the flash chamber further comprising an expandable membrane in fluid communication with the introduction needle.

10. The insertion device of claim 1 further comprising a needle guard removably connected to the base portion.

11. The insertion device of claim 1 wherein the top portion further comprising an opening to at least a portion of the flash chamber whereby the flash chamber may be viewed.

12. The insertion device of claim 1 , further comprising:
a locking mechanism, wherein as the top portion advances with respect to the base portion, the locking mechanism moves from an unlocked position to a locked position, whereby in the locked position, the top portion is positioned about the needle.

13. The insertion device of claim 1 , wherein the catheter further comprising:
a distal end comprising a non-perpendicular angle to the axis of the catheter and conforming to a keel of the introduction needle.

14. An insertion device comprising:
a base portion;
a top portion slidably connected to the base portion;
a substantially cylindrical flash chamber, the flash chamber having an inlet and adapted for connection to an introduction needle, wherein the top portion slidably engages with the flash chamber; and
a locking mechanism having a first end and a second end, the locking mechanism located on the base portion; and
a clip connected to the top portion, wherein the clip adapted to accommodate and control the locking mechanism and wherein the clip slidably engages the locking mechanism,
wherein as the top portion slidably advances with respect to the base portion, the clip slidably advances from the first end of the locking mechanism to the second end of the mechanism, whereby the locking mechanism moves from an unlocked to a locked position and whereby in the locked position, the top portion is positioned about the introduction needle.

15. The insertion device of claim 14 , wherein the flash chamber further comprising an insert.

16. The insertion device of claim 14 , wherein the insert is a cylindrical insert.
