Placing Seldinger kits in totally a totally closed procedure

 |
Due to the unique design of our needle free valve, you are able to place Seldinger kits as a totally closed procedure: |
|
1 |
The inside of the valve is similar to the shape of the Seldinger needle, allowing smooth passage of the guide wire. |
2 |
The valve is central-opening which allows guide wire access,
This is clinically useful when: |
* |
Placing central venous (jugular) catheters as the lumens can be primed with fluid and the placement avoids blood seepage. |
* |
Placing Seldinger chest drains as there the risk of worsening or inducing a pneumothorax is greatly reduced. |
Click the link for more details on our needle-free valve, We recommend having two valves to hand before you start, in case the first valve is damaged by the guide wire during placement. It is also important that you use the guide wire holder as this makes guide wire placement much easier through the valve. |
|
To place your Seldinger device as a closed system: |
|
1 |
Attach the valve to the Seldinger needle |
2 |
Check that the guide wire moves freely and back the wire into the holder hub to protect the tip |
3 |
Attach syringe firmly to the valve |
4 |
Place the needle as required, aspirate to ensure correct positioning |
5 |
Connect the guide wire holder to the valve and advance the wire into the Seldinger needle |
6 |
AS SOON as the wire is advanced into the needle remove the holder from the valve, leaving the wire in place. |
7 |
Advance the wire a suitable distance then, holding the wire, gently remove the needle; the needle and valve will pass over the wire. |
8 |
If you need to use the tissue dilator, attach the valve to this and advance over the guide wire to use as normal. The wire will pass out through the valve leaving the system closed. Remove as per needle when dilation is completed. |
9 |
Attach the valve to the distal channel of your Seldinger catheter and advance over the guide wire as usual. Again, the wire will pass out through the valve. Continue until the catheter is fully placed. |
10 |
Holding the catheter or valve, gently remove the guide wire. |
11 |
Inspect the valve surface. If there is damage evident, or the valve margins have separated or stepped at all, the valve should be replaced. Close the slide clamp or c-clamp on the catheter, replace with the spare valve, open the clamp then use the catheter as normal. |
The valve must be inspected and swabbed prior to every activation to ensure correct aseptic function. |
