[0028] In this embodiment, the inflation tube 1010 is disposed inside the blood drawing tube 107 , and the blood drawing tube 107 is disposed inside the drug adding tube 103 .

[0029] In this embodiment, the inflation mechanism 2 includes a gas filling tube 201, the outer periphery of the upper end of the gas filling tube 201 is fixedly connected to the inflation bag 202, the inner lower part of the gas filling tube 201 is fixedly connected to a sliding frame 203, the inner sliding frame 203 is slidably connected to a slide rod 204, the lower end of the slide rod 204 is fixedly connected to a baffle 205, the middle part of the upper end of the baffle 205 is fixedly connected to a spring 206, the left upper end opening of the gas filling tube 201 is fixedly connected to an air intake pipe 207, the inner middle part of the air intake pipe 207 is fixedly connected to a sliding frame 208, the left end of the sliding frame 208 is fixedly connected to a slide rod 209, and the middle part of the right end of the slide rod 209 is fixedly connected to a baffle 2010.

[0032] Specifically, the hemostatic device is inserted into the patient's vagina until the hemostatic ball 101 is inserted into the bleeding point of the patient's lower uterine segment, the inflation bag 202 is pressed, and the gas inside the inflation bag 202 enters the interior of the gas filling tube 201, and the blocking piece 1 205 is squeezed to slide downward, so that the lower end opening of the gas filling tube 201 is opened, and the gas enters the interior of the inflation tube 1010 through the gas filling tube 201, and then enters the interior of the expansion ball 109, supporting the left end of the hemostatic device. When the inflation bag 202 is released, the blocking piece 1 205 is re-fitted with the lower end of the gas filling tube 201 by the spring 1 206. At this time, the interior of the inflation bag 202 is in a negative pressure state, so that the slide bar 209 slides to the right inside the air inlet pipe 207, thereby allowing the air to enter the interior of the gas filling tube 201 from the left end of the air inlet pipe 207, and then enter the interior of the inflation bag 202, and repeat the operation. , repeatedly press the inflation bag 202 until the hemostatic ball 101 expands to block the bleeding point. At this time, insert the dosing needle 4 into the dosing inlet 1011, and send the hemostatic agent into the hemostatic ball 101 through the dosing tube 103, and send the hemostatic agent into the bleeding point of the patient's lower uterus through the drug outlet 102, and insert the blood drawing needle 5 into the blood drawing outlet 1012 to suck out the remaining blood and excess agent in the patient's uterus. Through the cooperation of the hemostatic mechanism 1 and the inflation mechanism 2, the bleeding point of the patient's lower uterus is compressed, which can achieve the effect of hemostasis, and through the cooperation of the hemostatic mechanism 1, the dosing needle 4 and the blood drawing needle 5, it is possible to add hemostatic agents to the bleeding point of the patient's lower uterus, and the remaining blood and excess agent in the uterus can be sucked out, which is beneficial to the patient's recovery.

[0033] In this embodiment, the adjustment mechanism 3 includes an adjustment frame 301, a slide rod 302 is slidably connected to the inner right opening of the adjustment frame 301, a baffle 303 is fixedly connected to the left end of the slide rod 302, and a spring 304 is provided on the outer periphery of the slide rod 302.

[0036] Specifically, when the hemostatic ball 101 completely compresses the bleeding point in the lower segment of the patient's uterus, at this time, when the inflation bag 202 is pressed again, the expansion ball 109 can no longer expand, and the gas pressure inside the inflation tube 1010 increases, causing the baffle three 303 to slide out from the opening at the right end of the inflation tube 1010, completing the pressure relief. When the pressure inside the inflation tube 1010 is normal, the baffle three 303 is re-fitted with the inside of the right end opening of the inflation tube 1010 through the spring three 304, so that the gas will not leak out. By providing the adjustment mechanism 3 at the right end of the hemostatic mechanism 1, it is achieved that after the left end of the hemostatic ball 101 compresses the bleeding point, when the medical staff presses the inflation bag 202 again, the hemostatic ball 101 can no longer expand, thereby avoiding the medical staff from excessively pressing the inflation bag 202 and causing excessive compression of the patient's lower segment of the uterus, thereby reducing the patient's pain.

[0037] Working principle:

[0038] First, insert the hemostatic device into the patient's vagina until the hemostatic ball 101 is inserted into the bleeding point of the patient's lower uterine segment, press the inflatable bag 202, and let the gas inside the inflatable bag 202 enter the interior of the gas filling tube 201, squeeze the baffle 1 205 to slide downward, so that the lower end opening of the gas filling tube 201 is opened, and the gas enters the interior of the gas filling tube 1010 through the gas filling tube 201, and then enters the interior of the expansion ball 109, supporting the left end of the hemostatic device. When the inflatable bag 202 is released, the baffle 1 205 is re-fitted with the lower end of the gas filling tube 201 through the spring 1 206, and now the interior of the inflatable bag 202 forms a negative pressure The state causes the second slide bar 209 to slide to the right inside the air inlet pipe 207, thereby allowing air to enter the inside of the air filling pipe 201 from the left end of the air inlet pipe 207, and then enter the inside of the inflation bag 202. Repeat the operation and repeatedly press the inflation bag 202 until the hemostatic ball 101 is expanded to block the bleeding point. At this time, the dosing needle 4 is inserted into the dosing inlet 1011, and the hemostatic drug is sent into the inside of the hemostatic ball 101 through the dosing tube 103. The hemostatic drug is sent to the bleeding point position of the patient's lower uterine segment through the drug outlet 102, and the blood drawing needle 5 is inserted into the blood drawing outlet 1012 to remove the residual blood inside the patient's uterus. The remaining blood and excess medicine are sucked out, and through the cooperation of the hemostatic mechanism 1 and the inflation mechanism 2, the bleeding point position of the patient's lower uterine segment is compressed, which can achieve the effect of hemostasis, and through the cooperation of the hemostatic mechanism 1, the dosing needle 4 and the blood-drawing needle 5, it is possible to add hemostatic medicine to the bleeding point position of the patient's lower uterine segment, and the blood and excess medicine remaining in the uterus can be sucked out, which is beneficial to the patient's recovery. When the hemostatic ball 101 completely presses the bleeding point of the patient's lower uterine segment, at this time, when the inflation bag 202 is pressed again, the expansion ball 109 can no longer expand, and the inside of the inflation tube 1010 The gas pressure increases, causing the baffle three 303 to slide out of the opening at the right end of the inflation tube 1010, completing the pressure relief. When the internal pressure of the inflation tube 1010 is normal, the baffle three 303 is re-fitted with the inside of the right end opening of the inflation tube 1010 through the spring three 304, so that the gas will not leak out. By providing the adjustment mechanism 3 at the right end of the hemostatic mechanism 1, after the left end of the hemostatic ball 101 compresses the bleeding point, when the medical staff presses the inflation bag 202 again, the hemostatic ball 101 cannot expand again, thereby avoiding the medical staff from excessively pressing the inflation bag 202 and causing excessive compression of the patient's lower uterine segment, thereby reducing the patient's pain.
