Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to an infusion port butterfly wing needle.
Background
An implanted venous transfusion port (called as a transfusion port for short) is a closed venous transfusion system which can be completely implanted into a body and mainly comprises an injection seat for puncture and a venous catheter. The syringe holder is a space for storing liquid, called reservoir, and the catheter is connected to the syringe holder by a catheter lock. When the transfusion port is used for transfusion, the injection seat is required to be used as the center for conventional disinfection, and the butterfly wing needle is punctured to establish a central venous transfusion passage. Generally, during continuous infusion, the butterfly needle is replaced 1 time per week, and the condition of the puncture site needs to be observed at any time. The removal of the implanted port after completion of infusion is the last step in the use and maintenance of the venous port, however, the conventional clinical removal method is that a nurse fixes the base of the port with one hand and holds the needle with the other hand to remove the needle. However, in the traditional needle pulling operation process, because the force required by needle pulling is large, certain back force can be generated, the hand used for fixing the base of the transfusion port is easy to hurt, the needle stick injury is caused, and the butterfly wing needle is complex to operate and is not easy to fix.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the butterfly wing needle in the prior art that the butterfly wing needle is difficult to fix and is difficult to pull out, and providing the butterfly wing needle for the transfusion port.
In order to achieve the above purpose, the utility model adopts the following technical scheme:

Preferably, a dressing sheet is adhered to the top end of the first wing sheet, and a patch is arranged at the tail end of the dressing sheet.
Preferably, a dressing sheet is adhered to the top end of the second wing sheet, and a patch is arranged at the tail end of the dressing sheet.
Preferably, the outer side of the second connecting block is in sliding fit with the inner side of the limiting block.
Preferably, the first connecting block is provided with a long hole.
Preferably, the second connecting block is provided with a long hole.
Compared with the prior art, the beneficial effects of the utility model are that:
1. after the fingers clamp the first wing piece and the second wing piece, the friction force is increased in the strip holes, so that slipping can be prevented, medical workers can pull out the needle head more easily, and the medical workers cannot injure themselves or patients due to the fact that the needle is pulled out difficultly.
2. The patch and the dressing sheet are matched to fix the butterfly wing needle, so that the nursing staff can observe the skin condition of the puncture part conveniently, and the whole device is convenient to fix.
