Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, in particular to a compression hemostasis device for postoperative care of liver cancer intervention. Background Art

[0002] Interventional surgery for liver cancer is usually performed through femoral artery puncture. The femoral artery is a large artery in the human body, relatively superficial and fixed. The pulsation can be felt below the midpoint of the inguinal ligament in the leg, which makes it easier for doctors to perform puncture operations. After the completion of the interventional surgery for liver cancer, compression hemostasis treatment is required, that is, the catheter is placed in the right femoral artery in the patient's groin. Since the femoral artery is the main trunk of the lower limb artery, the compression hemostasis device used in postoperative care for liver cancer intervention is directly fixed on the patient's leg. The existing panel includes a strap and a screw compression assembly threadedly connected to the panel. The specific principle is to use the strap to position the panel directly above the patient's bleeding port, and then use the thread of the screw to rotate so that the abutting end is pressed above the patient's bleeding port, thereby completing the hemostasis function. After the panel and the bleeding port are pressed tightly for a period of time, the panel and the patient's bleeding port are pressed tightly again. Due to the differences in coagulation function and bleeding port size of different patients, the compression force and compression time of the bleeding port are different. In addition, during the actual compression hemostasis process, the patient's bleeding port is covered, and the medical staff cannot observe the bleeding port. When the patient's bleeding port oozes blood, the compression force on the bleeding port cannot be increased in time, resulting in a prolonged hemostasis time of the bleeding port, which increases the patient's pain. At the same time, when the hemostasis effect of the bleeding port has reached the expected level, due to the inconvenience of observation by the medical staff and the judgment based on experience, the patient's bleeding port will be squeezed for a long time, which will cause complications such as skin damage and nerve damage, thereby reducing the quality of postoperative care for liver cancer intervention and the comfort of the patient.

[0028] Working principle: When it is necessary to stop bleeding at the bleeding point of a liver cancer patient after an interventional surgery, the gauze 402 is first rolled up onto the first winding roller. When the gauze 402 is rolled up onto the first winding roller, one end of the gauze 402 is first inserted into the limiting hole 501, and then the drive ring 601 is rotated. Under the action of the threaded engagement transmission, the conical ring 602 is driven to move. During the movement of the conical ring 602, the two limiting rods 503 are squeezed relative to each other to push the two limiting plates 502 closer to each other, and then as the drive ring 601 is continuously rotated, the limiting plates 502 are pushed closer to each other. The conical ring 602 will push the two opposite limiting rods 503 closer together, so that the two limiting plates 502 are against the side walls of the gauze 402. After one end of the gauze 402 is connected and fixed to the side wall of the first winding roller, the motor 405 is started to drive the first winding roller to rotate, and then the gauze 402 is rolled onto the side wall of the first winding roller. After the gauze 402 is rolled onto the first winding roller, the other end of the gauze 402 is passed through the sliding holes on the two opposite side walls of the fixing box 1, and is connected and fixed to the second winding roller 404 through the limiting assembly 5. After the gauze 402 is connected and fixed, the fixing box 1 can be placed on the bleeding point of the patient, and the gauze 402 can be against the bleeding point of the patient. Then, by winding the fixing belt 804, the fixing belt 804 is passed through the side of the patient's leg away from the fixing box 1 and inserted between the first rotating roller 802 and the second rotating roller 803. Then, the rotating handle 905 is rotated to drive the worm 903 on the rotating column 902 to rotate. The worm 903 and the worm wheel 904 are meshed with each other to transmit the action. The second rotating roller 803 is driven to rotate, and then the fixing belt 804 is driven to pass through the first rotating roller 802 and the second rotating roller 803 under the meshing action of the card slot 806 on the second rotating roller 803 and the card tooth 805 on the fixing belt 804, so that the fixing belt 804 is constantly close to the patient's leg. When the fixing belt 804 abuts against the patient's leg, the rotation of the rotating handle 905 can be stopped, and then under the tightening action of the fixing belt 804, the fixing box 1 is fixed to the patient's leg; After the fixing box 1 is fixed to the patient's leg, the micro air pump 204 is started, and then the airbag 201 is inflated by the air under the action of the air injection of the micro air pump 204. During the process of the airbag 201 being inflated by the air, the sliding plate 202 will be pushed to move close to the bleeding hole of the patient's leg. During the process of the sliding plate 202 moving close to the bleeding hole, the connecting component 3 will synchronously push each arc-shaped hemostatic plate 203 to move close to the patient's leg. When each arc-shaped hemostatic plate 203 is against the bleeding hole of the patient's leg, under the action of the squeezing force and the elastic expansion and contraction of the connecting component 3, each arc-shaped hemostatic plate 203 is pushed to generate a certain pressure on the skin of the patient's leg, thereby realizing the compression and hemostasis operation on the bleeding point of the patient's leg. In the process of each arc-shaped hemostatic plate 203 moving close to the patient's leg, the gauze 402 will be pushed against the patient's bleeding point. As the micro air pump 204 continues to work, the air pressure in the airbag 201 will continue to increase, thereby continuously increasing the pressure of the arc-shaped hemostatic plate 203 on the patient's bleeding point. After the barometer 206 shows that the pressure of the airbag 201 has reached the set standard, the micro air pump 204 stops working. At this time, due to the initial compression of the bleeding point, a certain amount of blood will ooze out of the bleeding point and be adsorbed by the gauze 402. After a period of compression on the bleeding point, if the amount of exuded blood increases, the amount of blood adsorbed on the surface of the gauze 402 will continue to increase, which will cause The blood-stained area on the surface of the gauze 402 is enlarged. At this time, the image sensor 7 detects that the compression effect on the bleeding point on the patient's leg is insufficient, so that the bleeding point is still bleeding. At this time, the micro air pump 204 can be started again to increase the internal pressure of the airbag 201, thereby increasing the compression force of each arc-shaped hemostatic plate 203 on the bleeding point. Thus, the image sensor 7 detects the blood-stained area on the surface of the gauze 402, and can effectively judge the hemostatic effect on the patient's bleeding point, thereby avoiding the bleeding point being covered and the medical staff being unable to observe the hemostatic effect and timely adjusting the compression force on the bleeding point, thereby improving the compression hemostasis effect and intelligence of the bleeding point after the interventional surgery of liver cancer patients. At the same time, after compressing the bleeding point of the patient for a certain period of time, when the blood area on the surface of the gauze 402 does not change, the air pressure in the airbag 201 can be reduced by opening the control valve on the air outlet pipe 205. Thereby reducing the pressure of the arc-shaped hemostatic plate 203 on the patient's bleeding point, and then, starting the two motors 405, so that the first winding roller releases the gauze 402, and the second winding roller 404 winds up the gauze 402, so that the gauze 402 on the patient's bleeding point is replaced. After the replacement of the gauze 402 is completed, starting the micro air pump 204 again, so that the arc-shaped hemostatic plate 203 maintains the original pressure on the bleeding point. After a period of compression, if there is no obvious blood staining on the surface of the gauze 402, it can be judged that the hemostasis of the patient's bleeding point is completed. At this time, the air pressure of the airbag 201 is slowly reduced through the air outlet pipe 205, and the pressure on the patient's bleeding point can be gradually released, thereby avoiding complications such as skin damage and nerve damage to the patient caused by long-term compression of the bleeding point, thereby improving the quality of postoperative care for liver cancer intervention and the comfort of the patient.
