Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a U-shaped secondary fixer for an indwelling needle. Background Art
[0002] The intravenous indwelling needle is also called the intravenous cannula needle. When used, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely in the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion treatment. The extension tube outside the indwelling needle needs to be fixed outside the puncture port in a U-shaped fixing manner. The U-shaped fixed extension tube uses the principle of a U-shaped communicating vessel in physics. When there is only one liquid in the communicating vessel, when the liquid does not flow, the pressure on the left and right sides of the U tube is equal, and the liquid levels in each container remain level, which can reduce blood return in the catheter;
[0003] When fixing it, the needle seat part needs to be completely covered with a film to form a completely closed sterile area. At the same time, the extension tube needs to be fixed with tape to keep it in a U-shape. The existing fixing method fixes the extension tube to the skin through the tape. During infusion, the infusion tube needs to be connected to the extension tube. When the infusion tube is affected by external forces such as traction, the extension tube will be directly pulled, and the extension tube is prone to traction and deformation. At the same time, the needle seat part is also prone to traction, resulting in curling of the film covering position, which affects the protection of the puncture site and is prone to the risk of slipping of the indwelling needle.
