The compression device 2 includes a lower seat 201 disposed below the housing 1. One side of the middle part of the lower seat 201 is provided with a hand pressing plate 202, and the hand pressing plate 202 is used for supporting and placing the arm of the patient. The bottom of the hand pressing plate 202 is fixedly connected with a second spring 203, the other end of the second spring 203 is abutted to a cover plate seat 204, and the cover plate seat 204 is fixedly connected with the lower seat 201 through screws.

As shown in fig. 5, the pressing device 2 further includes two sensor mounting holes 205 disposed at the bottom of the casing 1 and facing the lower base 201, each sensor mounting hole 205 is engaged with a snap connector 206, and the snap connectors 206 are in a snap style and can be engaged with the sensor mounting holes 205. The bottom of the snap connector 206 is fixedly connected with a mounting seat 207, and the bottom of the mounting seat 207 is adhered with a compression hemostasis head 208.

The arm of the patient is inserted between the compression hemostasis head 208 and the hand press plate 202, the distance between the hand press plate 202 and the compression hemostasis head 208 is gradually reduced through the elastic device 3, and finally the hand press plate 202 and the compression hemostasis head 208 are tightly pressed on the wound of the patient, so that the artery at the wound of the patient achieves the purpose of compression hemostasis.

As shown in fig. 6, 7 and 8, the tensioner 3 includes a first belt groove 31 disposed on the lower seat 201. The lower base 201 is provided with two first notches 32 corresponding to the two first notches 32, and the shell 1 is provided with a second matched notch 33. A buckle belt 34 is arranged in the groove. Two ends of the buckle belt 34 respectively pass through the two first belt notches 32, one end of the buckle belt 34 passes through the first belt notch 32 and the second belt notch 33 and is fixedly connected with a buckle belt column 35, and the buckle belt column 35 is fixedly connected in the shell 1. The other end of the buckle belt 34 passes through the first belt notch 32 and the second belt notch 33 and is fixedly connected with a roller 36.

The take-up unit 3 further comprises a take-up mechanism 37 for winding;

the tightening mechanism 37 comprises a mounting hole 301 arranged at the center of one side of the shell 1, and the roller 36 is slidably mounted in the mounting hole 301. The roller 36 is hollow in the middle and is fixedly provided with a center seat 302. A first spring 303 is wound around the central seat 302, and one end of the first spring 303 abuts against the roller 36 in the middle of the roller 36. The other end of the first spring 303 abuts against a rear cover 304. The rear cover 304 is fixedly connected with the housing 1 through screws. A screw hole 305 is formed in the middle of the rear cover 304, a safety screw 306 is screwed into the screw hole 305, and the safety screw 306 is finally abutted against the center base 302. The safety screw 306 needs to be assembled and disassembled by using a special tool, so that the patient can not disassemble the hemostat in the using process. The bottom of the lower seat 201 is provided with a rear cover plate 3014, and the rear cover plate 3014 is in screw connection with the lower seat 201. The rear cover 304 can be attached and detached only after the rear cover 3014 is opened.

A ratchet 308 is provided around the roller 36 and a knob 307 is provided through one end of the mounting hole 301. The ratchet 308 is fitted with a moving pawl wheel 309. A fixing column 3010 is arranged in the middle of the movable jaw wheel 309 in a penetrating manner. The fixed column 3010 is sleeved with a pressing plate 3011, the pressing plate 3011 is close to the movable claw wheel 309 but not abutted against the movable claw wheel, and the pressing plate 3011 is fixedly connected with the inner side of the shell 1 through screws. The pressing plate 3011 is used for placing the movable claw wheel 309 to be separated from the fixed column 3010. A torsion spring (not shown in the figure) is arranged between the movable jaw wheel 309 and the fixed column 3010. The fixing post 3010 is fixedly connected to the inner side of the housing 1. When the knob 307 is turned, the ratchet 308 is turned to wind the strap 34, so as to drive the lower base 201 to move toward the direction pressing the hemostatic head 208. When the artery wound of the patient is pressed by the compression hemostasis head 208, other blood vessels can not be pressed by the hemostat, thereby ensuring the blood in other blood vessels to be unblocked. The second spring 203 can reduce the sudden movement of the position of the artery wound of the patient caused by pressure change and the influence of pressure adjustment on the artery wound of the patient when the pressure is finely adjusted by the knob 307 when the hemostat is used by the patient.

When the safety screw 306 is not screwed into the screw hole 305, the knob 307 can be pressed inward to disengage the ratchet 308 from the movable pawl wheel 309, and at this time, the knob 307 is rotated reversely to rotate the ratchet 308 rapidly, so as to achieve the purpose of rapidly unwinding the buckle belt 34, and at this time, the distance between the hemostatic head 208 and the lower base 201 is pressed gradually. After unwinding, the knob 307 is released, and the roller 36 returns to its original position and engages with the pawl wheel 309 under the action of the first spring 303.

Preferably, a gear seat 3013 is fixedly disposed inside the housing 1 below the moving pawl wheel 309 for preventing the moving pawl wheel 309 from swinging downward to disengage the ratchet 308.

The sensing device 4 comprises a display screen 41 arranged on one side of the shell 1, and a pressure sensor electronic circuit element board 42 is fixedly arranged on the back of the display screen 41. The pressure sensor electronic circuit element board 42 is connected with a switch 43 and a power source 44 through electric wires, the power source 44 is arranged inside the housing 1, and the switch 43 penetrates through the housing 1 and is provided with a switch 43 button. The pressure sensor electronic circuit component board 42 is connected with two sensor chips 46 through electric wires, and the two sensor chips 46 are respectively connected with two sensor bases 47. Each sensor seat 47 is provided with a connecting hole 48 at the middle part, and a snap connector 206 passes through the sensor mounting hole 205 and is clamped with the connecting hole 48 on the sensor seat. On one hand, the arrangement of the second spring 203 can make the accuracy of the tested pressure higher through the reaction force of the second spring 203.

The whole working process is as follows:

1. the switch 43 button is turned on, so that the pressure sensor electronic circuit element board 42 starts operating, and the safety screw 306 is tightened. The patient passes an arm between the compression hemostasis head 208 and the hand press 202 with the patient wound between the compression hemostasis head 208 and the hand press 202;

2. rotating the knob 307 to enable the roller 36 to rotate to roll the fastening belt 34, wherein the fastening belt 34 is wound on the roller 36 and drives the lower seat 201 to move towards the direction of pressing the hemostatic head 208 until the artery wound of the patient is pressed by the pressing hemostatic head 208;

3. the two sensing chips 46 sense the reverse pressure applied to the compression hemostasis head 208, information is transmitted to the pressure sensor electronic circuit element board 42, and after information processing, the pressure value is displayed on the display screen 41, and the reason for arranging the two sensing chips 46 is to improve the measurement precision;

4. when it is necessary to disassemble the hemostat described herein, the knob 307 is pushed inward, so that the ratchet 308 is separated from the movable jaw wheel 309. The button is rotated in the opposite direction to unwind the buckle strap 34, and the buckle strap 34 is unwound to press the hemostatic head 208 away from the hand press 202, so as to pass the arm of the patient.
