Description

Next, the above blood modifying agent will be described in detail. The blood modifying agent is about 0.00 to about 0.05 g of IOB of about 0.00 to about 0.60, a melting point of about 45 ° C. or less, and 100 g of water at 25 ° C. Water solubility.

[Example 6]
[Surface tension of blood containing blood modifying agents]
The surface tension of blood containing a blood modifying agent was measured by a pendant drop method using a contact angle meter Drop Master 500 manufactured by Kyowa Interface Science Co., Ltd. The surface tension was measured after adding a predetermined amount of blood modifying agent to sheep defibrinated blood and shaking sufficiently. Although the measurement is automatically performed by the instrument, the surface tension γ is obtained by the following equation (see FIG. 16).
