Description

Technical Field

[0001] The utility model relates to the technical field related to tunnel needles, in particular to a subcutaneous tunnel needle for PICC placement. Background Art

[0002] Tunnel needle PICC refers to a new technology for inserting a central venous catheter through a peripheral vein. The difference from conventional PICC is that by establishing a subcutaneous tunnel, the blood vessel puncture point is kept at a certain distance from the catheter outlet, and the catheter outlet is transferred to a more suitable and advantageous position, so that the PICC catheter outlet avoids areas that are damp, sweaty, affect activity, and are inconvenient to use and maintain the catheter, and avoids skin with damage and scars. The development of this technology has greatly reduced the risk of catheter infection and thrombosis.

[0003] The existing tunnel needle is placed subcutaneously through the PICC tube at a 180-degree right angle. When the PICC tube and the tunnel needle move, the tunnel needle tip may move and puncture the PICC tube, causing damage to the skin or soft tissue at the tube site, infection, hematoma, etc. Utility Model Content

[0004] The purpose of the utility model is to provide a PICC catheter subcutaneous tunnel needle to solve the problems raised in the above background technology.

The PI CC catheter and the needle fixing sleeve prevent the PI CC catheter and the tunnel needle from moving, preventing the tunnel needle from moving and puncturing the PI CC catheter, and preventing damage, infection, hematoma, etc. to the skin or soft tissue at the catheterization site.

[0017] The tube end sleeve and the PI CC needle tube sleeve can wrap around the PI CC catheter subcutaneous tunnel needle tube to prevent the PI CC catheter subcutaneous tunnel needle tube from directly contacting the subcutaneous tissue or soft tissue. The tube end sleeve is connected and installed on the packaging end through the needle end sleeve. The packaging end is sealed by the blocking sleeve, which facilitates the connection of the PI CC catheter subcutaneous tunnel needle through the needle end sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
