Description

Technical Field

[0001] The utility model relates to the technical field of hemostasis, in particular to a hemostasis auxiliary fixation device. Background Art

[0002] Blood is mostly collected from veins and radial arteries in the hematology department. The radial artery blood collection method is to find the radial artery pulsation on the outside of the forearm, select the puncture site, draw a small amount of heparin with a 5ml syringe, fill the needle with heparin, fix the radial artery with the index and middle fingers of the left hand, hold the syringe with the right hand, and insert the needle vertically between the middle finger and index finger. When there is a pulsation at the needle tip, it means that the radial artery is touched. Insert the needle slightly further and blood can be seen flowing into the syringe. Draw 4-5ml of arterial blood, pull out the syringe, and quickly plug the syringe needle. Press the puncture site with a sterile cotton swab until the bleeding stops. Radial artery blood collection is used for blood gas analysis and to assess whether the patient is suffering from hypoxia, etc.

[0003] The existing radial artery puncture hemostasis has the following problems:

[0004] When applying pressure to stop bleeding at the puncture site of a patient with radial artery puncture, the pressure needs to be released for ten seconds every five minutes. The purpose is to prevent obstruction of venous return and avoid uncomfortable symptoms such as numbness and swelling at the patient's limb extremities. The existing method of stopping bleeding is to use a cotton swab to press the puncture site, and the pressure needs to be readjusted after the pressure is released from the patient.
