Movable body movably seals the adjusting cavity, and the motion of the regulating part changes the volume of the adjusting cavity and changed via described
Compressing chamber is delivered to the pressure of the pressuring piece.
So, when the motion of regulating part makes the volume of adjusting cavity change (such as diminishing), due to adjusting cavity and compressing chamber
Connection, thus make the volume change (such as diminishing) of the two fluid cavity formed, thus make the pressure respective change in fluid cavity
(such as becoming big), the change of this Fluid pressure are delivered on the pressuring piece of sealing compressing chamber so that pressuring piece is (in its compressing
End) on pressure respective change (such as become big), patient's bleeding position is thus acted on bigger oppressive force and oppressed only
Blood operates.Vice versa, can also correspondingly reduce the pressure of hemostasis by compression.The pressure change applied by governor motion is delivered to
The pressure side of the pressuring piece directly contacted with patient's bleeding position, it is achieved in the regulation of pressing type hemostasia pressure.
Such compression hemostasis device, it is not necessary to external gas or fluid supply provide operating pressure, but in relative envelope
The regulation of pressing type hemostasia pressure is realized in the system closed, not only compact-sized size is small, and easy to operate.
