Fixing device for deep vein catheterization

Abstract

The invention relates to the field of medical auxiliary devices, in particular to a fixing device for deep vein catheterization. The fixing device for deep vein catheterization comprises a first fixing unit and a second fixing unit, the first fixing unit comprises a cushion layer, and a Y-shaped strip-shaped seam is formed in the cushion layer; the second fixing unit comprises a fixing box and a pasting assembly, an opening and an air hole are formed in the fixing box, a containing groove with a downward opening is formed in the bottom of the fixing box, the pasting assembly comprises two fixing blocks and a plurality of fixing rods, the two fixing blocks are detachably connected with the containing groove, and the two fixing blocks are located on the two sides of the fixing rods correspondingly; the two ends of the fixing rod are detachably connected with the two fixing blocks respectively, the fixing rod can rotate relative to the fixing blocks at the same time, and a pasting part and a shielding part are arranged on the fixing rod. The fixing device for the deep venous catheter can fix the deep venous catheter, and meanwhile, the skin of a patient can be cleaned conveniently.

Description

technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to a fixing device for deep vein catheterization. Background technique [0002] Deep vein catheterization is to implant catheters into the internal jugular vein, femoral vein, subclavian vein and other important veins of the human body, and directly inject drugs into the vein through the pipeline. It is a routine step after major surgical operations. Deep vein catheterization Tube has undeniable advantages, it makes infusion faster, safer and more effective. Taking the deep jugular vein infusion as an example, hypertonic drugs can avoid the stimulation and damage of blood vessels during infusion, and when patients need massive blood transfusion and fluid replacement, it can be used to observe the dynamic changes of blood volume. [0003] After the deep vein catheter is implanted into the human body, the end of the catheter is located outside the body, and at this time, the ...

Problems solved by technology

When the deep venous catheter needs to be fixed for a long time, sweat, dirt and dead skin will appear on the surface of the patient's skin. , when replacing, you need to tear off the adhesive tape from the deep venous catheter first. In the process of tearing off the adhesive tape, the adhesive tape is also easy to pull the deep venous catheter, resulting in the displacement of the deep venous catheter; on the other hand, fix the deep venous catheter Finally, it is difficult to clean the skin under the deep venous catheter. If things go on like this, the deep venous catheter will be contaminated, leading to deep venous catheter and adhesive tape infection, which is not conducive to the recovery of patients
