Description

Vein-pressing hemostatic patch

Technical Field

The invention relates to a medical hemostatic dressing, in particular to a vein pressing hemostatic patch.

Background

Arteriovenous blood sampling is a common examination item. After blood sampling, the needle hole is often pressed by a patient or others to stop bleeding by using a cotton swab, a cotton ball and the like. Subcutaneous congestion and even infection are easy to occur when the pressure is not in place. If the infant cries after blood sampling, pressing to stop bleeding is more difficult. If the bare limb is pressed for a long time in cold winter, cold catching may also occur. In daily life, pressure hemostasis is also needed for the skin to be collided and damaged to bleed, but the conventional band-aid, wound dressing and the like on the market cannot play the role. To overcome these drawbacks, various elastic pressure hemostatic patches have been developed. However, the hemostatic patch has a complex structure, is troublesome to operate, has poor use experience, and increases the manufacturing cost and the use cost.
