Technical Field
[0001] The utility model relates to the technical field of limb venous indwelling needle protection devices, in particular to a limb venous indwelling needle protection device. Background Art
[0002] As we all know, intravenous catheters are widely used in clinical practice because they can reduce the stimulation of repeated punctures and vascular damage. The retention time of intravenous catheters is 72-96 hours. Using transparent or translucent dressings to cover the catheter site has become the most common method in clinical practice. However, with the movement of the patient's limbs and the friction during the movement, the transparent dressing of the intravenous catheter is easy to curl or even be lifted, which will cause the intravenous catheter to fall out and fail to achieve the expected retention time. Frequent replacement of dressings and intravenous catheters not only takes time and wastes medical supplies, but also increases the economic burden on patients.
[0003] Existing indwelling needles are prone to fall out during use, which will affect daily activities and cause great discomfort to patients. Therefore, we propose a limb vein indwelling needle protection device to solve the above problem. Utility Model Content
