Description

Technical Field

[0001] The utility model relates to the technical field of fixing and anti-pulling devices, in particular to an anti-pulling type elderly care infusion cannula fixing device. Background Art

[0002] The infusion cannula used in elderly care generally refers to a device used to fix an intravenous needle or catheter. These cannulas are designed to ensure the stability of the venous channel and prevent the intravenous needle from falling off or shifting due to patient activity. The falling off or shifting of the intravenous needle will lead to the interruption of infusion or drug delivery, and the intravenous needle or catheter needs to be relocated, which delays the treatment process. This is especially important for patients who rely on infusion therapy. After the intravenous needle falls off, the needle or catheter may irritate the surrounding tissues, causing pain and discomfort to the patient, especially local inflammatory reactions may occur at the venous puncture site or around the catheter.

[0003] After searching, it was found that the Chinese patent with publication number CN219323734U discloses an infusion cannula fixing and anti-pulling device for elderly care, including: an infusion bottle, an infusion needle, a fixing frame, a support seat, an active rotating rod, a driven rotating rod, a docking seat, a connecting rod, a spring, a linkage rod and a clamping seat. In this anti-pulling device, the active rotating rod is pulled to rotate by the elastic force of the spring, thereby driving the clamping claw to link and clamp the infusion needle through the clamping claw, thereby achieving the fixing effect of the infusion needle, preventing the infusion needle from falling off the infusion bottle under the action of external tension during infusion, thereby effectively eliminating the safety hazard, and by setting the clamping claw to a rotatable structure, the device can be applied to infusion needles of different models, thereby improving its scope of application. A linkage rod is provided between the bottom of the active rotating rod and the driven rotating rod in this anti-pulling device, and both ends of the linkage rod are rotatably connected to it through bearings, so that the active rotating rod and the driven rotating rod can be linked synchronously.

[0004] The above-mentioned existing infusion cannula fixing and anti-pulling device has the following defects when used: when the infusion needle needs to be inserted into the infusion bottle, it needs to be inserted from the through hole at the center of the support base. In addition, due to the small opening of the through hole, the insertion is time-consuming and laborious; at the same time, the infusion bottle is fixed only by the fixing frame and the screw rod, and the stability is poor.
