Results The hemostasis was rapid and accurate with hemostatic pressure in the range from 190 to 230 mmHg. The excellent effect guarantees the diagnosis, observation, bandaging and secure transmission of victims until they were sent to the operation room. Conclusion It is reliable to use portable auto-haemostat machine on body's limbs in clinic works.

The instrument is com posed of such components as SCM,pressure sensor,electric pump,magnetic valve and sleeve-type gasbag.It can control the hemostatic pressure,hemostatic time and slack time automatically.So the ischemic necrosis can be avoided thoroughly thr ough it.With the small volume,light weight,low power consumption and convenient operation,the instrument is fit for emergency treatment of mass casualties.
