Description

Technical Field

[0001] The present invention relates to the field of nephrology instruments, and in particular to a hemostatic compressor used in nephrology surgery. Background Art

[0002] During nephrology surgery, a fistula puncture needle is typically used to puncture a patient's arteriovenous fistula. Due to the large puncture site, high blood flow and pressure in the fistula, coupled with the use of anticoagulants, bleeding from the fistula site is often difficult to stop when the needle is removed after hemodialysis, and may even cause swelling and subcutaneous ecchymosis. Existing puncture site compression and hemostasis fixation devices, such as Chinese Utility Model Patent Publication No. CN212346620U, disclose a device comprising a fixing bag with a sealed zipper fixedly attached to its surface, a breathable fabric fixedly attached to its bottom, an elastic band fixedly attached to one side of the bag, a Velcro surface A fixedly attached to the surface of the elastic band, and a fixing band fixedly attached to the other side of the bag, a Velcro surface B fixedly attached to the surface of the fixing band. This type of fixing device primarily consists of a fixing band structure that is adhered to the patient's puncture site by adhesive bonding. However, this method does not effectively compress the puncture site, resulting in less than ideal hemostasis. Summary of the Invention
