Wherein, the measuring belt 611 is provided with a measuring scale, and the second monitoring piece is arranged on the connecting ring 612 matched with the insertion end 613. The second monitoring element is capable of measuring the measurement value from the measurement scale and reading the measurement value in order to upload the second information, i.e. the measurement value, to the controller 51. As shown in fig. 1 and 2, the radial artery compression hemostat further includes a finger tip oximetry clip 70, the finger tip oximetry clip 70 being in signal communication with the controller 51. The finger tip blood oxygen measuring clamp 70 is sleeved at the finger tip on the same side of the puncture point, and is connected with the controller 51 through a first lead in a signal manner, and the finger tip blood oxygen measuring clamp can monitor the blood oxygen saturation level of a patient. When the blood oxygen saturation is lower than 90% or the basic blood oxygen level is too low, that is, finger end ischemia is considered, after the third information is transmitted to the controller 51, the controller 51 controls the lifting device 40 to lift, the lifting speed of the lifting device 40 is increased, the pressure of the pressing piece 30 is reduced, and the risk of finger end ischemia is reduced. The technical scheme of the sample embodiment has more comprehensive and objective monitoring indexes, and can monitor complications such as bleeding, finger tip hypoxia, nerve compression and the like more timely.

As shown in fig. 1 and 2, the pressing member 30 is a transparent pressing ring, so that bleeding can be observed. The transparent compression ring is preferably a rigid member.

As shown in fig. 1 and 2, the lifting device 40 includes a motor 41 above the fixing plate 10, a screw 42 penetrating the fixing plate 10, and a nut sleeved outside the screw 42 and fixed to the fixing plate 10.

The motor 41 drives the screw rod 42 to ascend or descend and drives the pressing member 30 to ascend or descend so as to change the amount of force applied to the puncture point by the pressing member 30. After the compression member 30 is compression-stopped for half an hour, the motor 41 starts to continuously rotate in the counterclockwise direction at an angular velocity of a preset pi/1800 rad/sec, and the screw 42 is driven to rise to reduce the pressure applied to the radial artery puncture site by the compression member 30. The motor 41 is controlled and connected by a controller 51 through a signal line 22, and the rotation speed is dynamically adjusted under the control of instructions of the controller 51. When the first monitoring member 31 senses that the bleeding speed of the puncture site is greater than 1 ml/second, the first information is uploaded to the controller 51, the controller 51 gives an instruction to the motor 41, the motor 41 stops rotating, simultaneously starts rotating clockwise, and drives the screw rod 42 and the pressing member 30 to descend simultaneously, so that the pressure on the puncture site is increased. Half an hour after the first monitoring member 31 senses the bleeding is stopped, the controller 51 resends the instruction to resume the counterclockwise rotation of the motor 41 at the preset rotation speed.

After the second information and the third information are transmitted to the controller 51, the controller 51 transmits a command to the motor 41 to increase the speed of counterclockwise rotation to control the speed of ascent of the elevating device 40.

When the motor 41 is lifted or lowered along with the screw rod 42, the motor 41 can be prevented from rotating relative to the screw rod 42 due to the rotation-stopping engagement of the first rotation-stopping surface and the second rotation-stopping surface, so that the motor 41 can move up and down only along the extending direction of the support 11.

As shown in fig. 1 and 2, in order to facilitate mounting of the controller 51 on the fixing plate 10, the fixing plate 10 is provided with a mounting groove into which the controller 51 is inserted.

As shown in fig. 1 to 3, the radial artery compression hemostat further includes a display 52, and the display 52 is in signal connection with the controller 51.

Connected to a patient worn controller 51 via bluetooth and can be recalled at a display 52 to view the patient's basic information.

The controller 51 is located at the center of the fixed plate 10 and is in control connection with the motor 41 through a second wire. By scanning the patient hospitalization wristband 21, basic information and test results of the patient are input, and various monitoring indexes such as bleeding amount and bleeding speed, forearm circumference, finger tip blood oxygen saturation and the like after the patient begins radial artery compression hemostasis are collected. When the first monitoring member 31 monitors that the bleeding speed exceeds a certain amount, the controller 51 instructs the motor 41 to rotate the motor 41 clockwise according to circumstances, increasing the pressure applied to the puncture site until bleeding is stopped. If the second monitoring element detects a significant increase in forearm circumference, a decrease in finger tip blood oxygen saturation below 90% or a significant decrease from baseline, indicating that compression is too tight, venous return is blocked or finger tip blood supply is limited, the controller 51 may instruct the motor 41 to rotate the motor 41 counterclockwise, reducing the pressure exerted by the compression element 30 on the puncture site. The first information, the second information and the third information are transmitted through the wireless module and displayed in the display 52, so that medical staff can conveniently and fully grasp the condition of a patient in time.

Therefore, the technical scheme of the embodiment not only can automatically change the decompression speed of the arterial compression hemostat, monitor the occurrence risk of complications such as bleeding, finger tip hypoxia, nerve compression and the like, but also can intelligently adjust the pressure applied to the puncture point according to objective monitoring indexes. And according to the comprehensive information, possible hemostasis strategies can be analyzed and explored, and the subsequent operation flow is optimized.
