Abstract
Description
Technical Field
[0001] The present application relates to the field of medical device technology, and more specifically, to a central venous line external access fixation device. Background Art
[0002] Several methods can be used to secure central venous lines:
[0003] 1. Bandage fixation method: Use a bandage of moderate width to fix the central venous line to the patient's skin. First, clean the skin near the line insertion point and apply an appropriate skin disinfectant. Then, wrap the bandage from the line insertion point, cross around the line until the two ends of the bandage overlap. Finally, tie the two ends of the bandage to ensure that the line is fixed to the skin.
[0004] 2. Attachment fixation method: Use some special films or tapes to stick the central venous line on the patient's skin. The advantage of this method is that the film or tape can be replaced at any time, which is convenient for cleaning and replacement.
[0005] 3. Clip fixation method: Use two small clips near the line insertion point to clamp the central venous line to the skin. The advantage of this method is that the tightness of the clip can be adjusted at any time to adapt to different skin conditions and line positions.
[0006] 4. Sling fixation method: Use a bracket with a sling to hang the central venous line on the patient. The advantage of this method is that it can reduce the patient's sense of restraint and avoid friction and damage to the skin.
[0007] A document with prior art publication number CN219050031U provides a central venous catheter external passage fixing device, which accommodates and protects the central venous catheter external passage through a cavity formed by buckling a box body and an upper cover. The upper cover is set to be transparent so that the arrangement of the internal catheter passage can be intuitively observed. In the care of critically ill patients in the ICU, it can solve the risks caused by improper catheter handling and improve work efficiency.
[0008] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is used, the pipeline is fixed by the limit clip, but the structure of the limit clip is simple, which can only fix the pipeline of fixed size and is not convenient for fixing pipelines of different sizes, resulting in poor practicality.
