Description

Technical Field

[0001] The utility model relates to a medical appliance, in particular to a pressurized hemostatic cotton pad for preventing bleeding after hemodialysis. Background Art

[0002] After hemodialysis, the traditional puncture point hemostasis operation is to manually press the sanitary cotton wool at the puncture point. The operation is time-consuming and labor-intensive, and it is also easy to cause bleeding and bacterial infection at the puncture point due to improper pressing.

[0003] The conventional hemostasis operation for the existing fistula puncture point is to first apply a bandage to the puncture point, then press it with a cotton ball pad, and then tie it with a tourniquet. The operation is cumbersome; moreover, when the patient moves his arm or puts down his sleeve, the cotton ball is likely to slip off, causing bleeding at the puncture point.

[0004] The Chinese utility model patent CN208942256U announced on June 7, 2019 discloses a tool for compression hemostasis of hemodialysis fistula, including a compression hemostasis component for compressing and stopping bleeding at the puncture point, and a pressure-applied compress for fixing the compression hemostasis component. The compression hemostasis component is provided with a long strip of fixing belt, and a placement cavity for inserting a sterile hemostatic cotton ball is provided in the middle of the fixing belt. The sterile hemostatic cotton ball is arranged perpendicular to the adhesive tape, and the pressure-applied compress is provided with a transparent film that cooperates with the compression hemostatic component, and an adhesive coating is provided around the inner surface of the transparent film. Utility Model Content

[0005] The utility model aims to provide a pressurized hemostatic cotton pad for preventing bleeding after hemodialysis. Two thick gauze pads are used to prevent the thick cotton ball from rolling and shifting to cause bleeding at the puncture point. The pressurized hemostatic effect can also be enhanced by a fixing belt. The utility model is suitable for patients with high pressure of autologous arteriovenous fistula, and the fixing belt can be used continuously.
