Gynecological hemostatic device

Abstract

The application relates to the technical field of postpartum hemostasis, and discloses a gynecological hemostasis device which comprises an extension flow guide mechanism and an inflatable compression hemostasis mechanism. One end of the extension flow guide mechanism away from the inflatable compression hemostasis mechanism is provided with an electric pressure relief mechanism, and both sides of the electric pressure relief mechanism are provided with mechanical pressure relief mechanisms. The gynecological hemostasis device can monitor and feedback control the internal air pressure in real time by means of the electric pressure relief mechanism during use. When the uterus contracts and extrudes the internal compression air bag to cause the air pressure to rise, the electric pressure relief mechanism can be quickly started to release pressure to maintain pressure stability. Meanwhile, the two sets of mechanical pressure relief mechanisms arranged in parallel can automatically work when the electric pressure relief mechanism fails or responds with delay, forming a double-redundancy protection mechanism, so that the compression effect of the device on the uterine cavity during the uterine contraction process is always within the preset safe pressure range, and the risk of excessive local pressure in the uterus is effectively prevented.

Description

Technical Field

[0001] This invention relates to the field of postpartum hemostasis technology, specifically to a gynecological hemostasis device. Background Technology

[0002] Postpartum hemorrhage includes three periods: from the time of delivery of the fetus to the time of delivery of the placenta, from the time of delivery of the placenta to 2 hours postpartum, and from 2 hours to 24 hours postpartum. It mostly occurs in the first two periods. Uterine atony is the main cause of postpartum hemorrhage. When the uterine contraction is insufficient, it cannot effectively compress blood vessels, leading to increased bleeding.

[0003] Ordinary balloon compression hemostasis devices mainly rely on balloon inflation to apply continuous and constant external pressure to the bleeding point to achieve hemostasis. However, they usually lack a pressure relief and adjustment mechanism and cannot adjust the pressure synchronously during the postpartum uterine contraction hemostasis process. If the balloon still maintains the original volume of gas after uterine contraction, the pressure inside the balloon will increase as the uterus contracts and squeezes, which will in turn lead to excessive local compression in the uterus. This will not only hinder the normal physiological contraction and involution process of the uterus, but may also affect the closure of blood sinuses in the uterine cavity, thereby increasing the risk of tissue ischemia or secondary hemorrhage.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This obstetric and gynecological hemostasis device, through its electric pressure relief mechanism, mechanical pressure relief mechanism, extension and diversion mechanism, and inflatable compression hemostasis mechanism, can monitor and control the internal air pressure in real time using the electric pressure relief mechanism. When uterine contractions compress the internal airbag, causing the air pressure to rise, the electric pressure relief mechanism can be quickly activated to release pressure and maintain stability. At the same time, through two sets of mechanical pressure relief mechanisms set in parallel, they will automatically take over when the electric pressure relief mechanism malfunctions or has a delayed response, forming a dual redundancy protection mechanism. This ensures that the device's compression of the uterine cavity during uterine contractions is always within the preset safe pressure range, effectively preventing the risks caused by excessive local pressure in the uterus.

[0017] This obstetric and gynecological hemostasis device, through its multi-port tube, electromagnetic switch valve, pressure sensor, exhaust connector, filter block, waste gas extension tube, inflation extension tube, bypass tube, electromagnetic check valve, threaded plug, and pressure gauge, can release pressure through feedback from the electromagnetic switch valve via the pressure sensor during use, and pressurize through feedback from the electromagnetic check valve via the pressure sensor, thereby ensuring constant pressure of the internal pressure balloon during uterine contractions.

[0018] This obstetric hemostasis device, through its components including a flow guide seat, damping seat, sealing piston, extension column, damping plate, micro-pressure spring, adjusting stud, compression spring plate, pressure regulating spring, pressure relief inlet and outlet, constant pressure hole, filter block, damping cavity, guide groove, sealing end seat, first sliding seal ring, second sliding seal ring, comparison plate, scale ring, inner through groove, damping hole, clearance airbag, pressure regulating torsion wheel, flow groove, guide protrusion, and liquid inlet, enables pressure relief by triggering the sealing piston with air pressure during use. The pressure relief value can be adjusted by twisting the pressure regulating torsion wheel. At the same time, the damping fluid and damping plate work together to filter out the instantaneous pressure increase caused by the mother's movement, avoiding misleading pressure relief, and ensuring that the constant pressure increase caused by uterine contractions can smoothly push the sealing piston open.

[0019] This obstetric and gynecological hemostasis device, through its diversion extension tube, anti-drainage bladder, threaded sleeve, liquid filling sleeve, liquid filling plug, contaminated blood extension and extraction tube, seepage ring groove, main ventilation channel, injection channel, contaminated blood extraction channel, and contaminated blood extraction hole, enables the flow of saline, contaminated blood, and air through the diversion extension tube during use, ensuring the normal operation of the device.

[0020] This obstetric and gynecological hemostasis device, through its internal pressure balloon, exudate groove, medical silicone sponge filling layer, external pressure balloon, hemostasis and exudate zone, and perforated rubber ring, can simultaneously compress and stop bleeding inside the uterus by utilizing the medical silicone sponge filling layer and the external pressure balloon, while also draining contaminated blood. Compared to traditional methods of draining contaminated blood through tubes, the evenly distributed exudate holes improve the uniformity of contaminated blood drainage. Attached Figure Description

[0042] The inflatable compression hemostasis mechanism includes an external compression airbag 404, a hemostasis and exudate zone 405, and a perforated rubber ring 406.

Compared with the traditional method of draining contaminated blood through tubes, the uniform distribution of seepage holes improves the uniformity of contaminated blood drainage.

[0043] Working principle:

[0044] When in use, adjust the pressure relief value of the air pressure sensor 103, twist the pressure regulating wheel 224 to adjust the pressure relief value by referring to the scale ring 220, so that the two pressure relief values ​​are the same, connect the blood and filth extension tube 306 to the external negative pressure suction pipe, connect the inflation extension tube 107 to the external positive pressure pipe, and close the passage of the electromagnetic switch valve 102.

[0045] Then, the contracted external pressure balloon 404 is inserted into the uterus, so that the hemostasis and exudate area 405 faces the position to be compressed. Then, the electromagnetic one-way valve 109 is opened to inflate the balloon. The airflow passes through the inflation extension tube 107, through the electromagnetic one-way valve 109, into the multi-port tube 101, and then through the threaded plug 110 and the main ventilation channel 308 into the internal pressure balloon 401 to inflate it. The position of the internal pressure balloon 401 is adjusted so that the perforated rubber ring 406 is aligned with the position to be compressed. By observing the change in the value of the pressure gauge 111, the electromagnetic one-way valve 109 is closed when the pressure reaches the pressure relief value and begins to relieve pressure.

[0046] Then, place the anti-loosening fluid bag 302 at the cervix and inject physiological saline into the upper liquid cap 304 using a syringe. The physiological saline enters the anti-loosening fluid bag 302 along the injection channel 309 to inflate it. Then, close the upper liquid plug 305 to prevent the device from easily falling out.

[0047] When the pressure regulating wheel 224 is turned, the pressure regulating wheel 224 drives the adjusting stud 207 to rotate. When the adjusting stud 207 rotates, it pushes the pressure spring plate 208 up and down. When the pressure spring plate 208 slides outward, the pressure regulating spring 209 extends, the pressure of the pressure regulating spring 209 on the damping plate 205 decreases, the combined force of the pressure regulating spring 209 and the micro-pressure spring 206 on the sealing piston 203 decreases, and the air pressure to push open the sealing piston 203 decreases. When the pressure spring plate 208 slides inward, the pressure regulating spring 209 contracts, the pressure of the pressure regulating spring 209 on the damping plate 205 increases, the combined force of the pressure regulating spring 209 and the micro-pressure spring 206 on the sealing piston 203 increases, and the air pressure to push open the sealing piston 203 increases. Thus, the pressure relief pressure can be adjusted by turning the pressure regulating wheel 224.

[0048] After the device is installed, the external negative pressure suction pipe is opened. The negative pressure is transmitted through the blood-stained extension suction pipe 306 and the blood-stained removal channel 310, so that a negative pressure is formed between the internal pressure balloon 401 and the external pressure balloon 404. This allows the blood-stained blood to pass through the perforated rubber ring 406 and enter the medical silicone sponge filling layer 403. Then, it enters the blood-stained removal channel 310 through the gaps in the medical silicone sponge filling layer 403. At the same time, the blood-stained blood at the cervix enters the blood-stained removal channel 310 through the blood-stained suction hole 311 and is then discharged through the blood-stained extension suction pipe 306. The slight negative pressure transmitted by the blood-stained removal channel 310 can also guide uterine contractions and assist uterine contractions to inhibit bleeding.

[0049] When the uterus contracts, the pressure on the seepage tank 402 increases the internal air pressure. The air pressure sensor 103 filters out the intermittent pressure increase signal and transmits the continuous pressure increase signal to the solenoid valve 102, causing the solenoid valve 102 to open. This avoids interference caused by the instantaneous pressure increase due to the mother's movement, thus achieving normal pressure relief. When the air pressure reaches the set value, the air pressure sensor 103 transmits the signal to the solenoid valve 102 to close it, thus preventing excessive pressure.

[0050] Meanwhile, when the air pressure increases to the pressure relief value and the electromagnetic switch valve 102 does not respond or does not respond in time, the air pressure will squeeze the sealing piston 203 to slide outward. If the electromagnetic switch valve 102 responds, the sealing piston 203 will reset due to pressure relief. When the air pressure changes instantaneously, the damping plate 205 will squeeze the damping fluid when it slides. It takes a certain amount of time for the damping fluid to pass through the damping hole 222. Therefore, the sealing piston 203 cannot quickly open the pressure relief vent 211 to relieve pressure, thereby avoiding pressure relief caused by the instantaneous pressure increase due to the change in the mother's body position. If the increase in air pressure is caused by normal uterine contractions, the air pressure will not return to normal after a period of time. Therefore, when the increase in air pressure is maintained, the sealing piston 203 will gradually open the pressure relief vent 211 after a period of time, and the damping fluid will pass through the damping hole 222 to achieve pressure relief.

[0051] When the air pressure is lower than the set value, the air pressure sensor 103 will send a signal to the solenoid one-way valve 109 to open it for inflation, thereby avoiding excessive depressurization.
