The second elastic member 246 has both ends connected to the movable plate 244 and the bracket 245, respectively, and presses the movable plate 244 against the annular step 243. The pressure regulating assembly 240 is used to regulate the pressure in the empty bag 210, and the pressure regulating assembly 240 is determined by the elastic force of the second elastic member 246. When the pressure in the empty bag 210 is too high, i.e. greater than the elastic force designed by the second elastic member 246, the air pressure pushes the movable plate 244, and the excess air in the empty bag 210 enters the buffer bag, until the pressure in the empty bag 210 is less than the pressure of the second elastic member 246, the movable plate 244 abuts against the annular step 243, and the pressure in the empty bag tends to be stable.

The specific method of using the compression hemostat 10 includes:

when in use, the box cover 252 of the protection box 250 is taken down, and the box body 251 is slid along the first connecting pipe 220 until the storage bin 230 is completely exposed; then, inserting the fixing strap 100 into the through hole 111 at the tail end of the fixing strap 100 from the beginning to the end, so that the fixing strap 100 forms a circle from the beginning to the end and the diameter of the circle is larger than that of the arm of the patient; establish fixed band 100 cover afterwards on the arm and remove patient's elbow joint top to let the patient assist with fixed band 100 and take, medical personnel carry out the blood sampling operation, in the twinkling of an eye of accomplishing the blood sampling, medical personnel move hemostatic pad 300 on the oppressive hemostat 10 on one hand to the blood sampling point and oppress on the blood sampling point, pull fixed tail end and drag fast on the other hand, fix firmly on the arm until fixed band 100. Then, the storage bin 230 is pressed, so that the air in the storage bin 230 enters the empty bag 210, the volume of the empty bag 210 expands to generate pressure, and the hemostatic pad 300 is firmly pressed at the blood sampling point, so that hemostasis can be realized. After hemostasis is completed, the patient only needs to stir the L-shaped sliding rod 121 in the direction away from the through hole 111, so that the L-shaped sliding rod 121 and the insertion hole 112 fall off, and the fixing band 100 can be taken down.

The compression hemostat 10: the hemostatic pad 300 is a cotton pad soaked with hemostatic drugs, which may be blood clotting rapidly. The fixing band 100 is used to fix the whole compression hemostat 10 to the needle hole, and performs both fixing and partial compression hemostasis. The fixing band 100 is clamped by the clamping component, so that the fixing band is convenient to fix and take down. The empty bag 210 is normally in an empty state, and after the whole compression hemostat 10 is fixed, the air in the storage bin 230 is squeezed into the empty bag 210, and then the pressure assembly 200 applies pressure to the hemostatic pad 3004 again, so as to increase the pressurizing effect. The isolation membrane 221 functions as a one-way valve to prevent the gas in the empty bag 210 from being guided, thereby affecting the pressurization effect. The support frame 223 can prevent the isolation film 221 from being deformed and further opening the gap 222 when the pressure of the isolation film 221 is too large in the direction of the empty bag 210; the protective pocket 250 serves to prevent the storage bin 230 from being accidentally compressed; the pressure regulating assembly 240 prevents the bag 210 from being emptied of too much air, which may cause excessive pressure on the arm and thus affect the comfort of the patient.
