Background technique

Postpartum hemorrhage is a serious complication during childbirth and an important cause of maternal death. When the amount of uterine bleeding is extremely large, if the bleeding cannot be stopped in a short time, it will endanger the life of the parturient. Therefore, uterine bleeding must be Immediately perform hemostatic treatment. When drug treatment is ineffective, the uterine cavity is usually filled with gauze to stop the bleeding. This method takes a long time to fill the process and causes severe pain stimulation to the parturient. It is difficult for the patient to bear it in the non-anesthesia state, which increases the risk of intrauterine infection and hemostasis slow. For this reason, the means of hemostasis through water bag compression has appeared in recent years, and the effect is better, and it will not harm the puerpera. However, there are still many problems in the existing water bag hemostasis methods, such as water bag is easy to leak, cannot press the uterus for a long time, and It is easy to slide out from the uterus, etc.; the search found that the Chinese utility model patent with the application number of 201620216576.6 discloses a hemostatic sac in obstetrics and gynecology, which uses the method of inflating the uterine sac to replace the water sac, which solves the problem of water leakage, and can be avoided by setting the vaginal sac. The uterine sac slides out, but there are still some problems. For example, the uterine sac is easily deformed, which affects the compression effect. The vaginal sac can prevent sliding out, but it cannot avoid sliding in. The uterine sac cannot be completely positioned, which affects the hemostasis effect. For this reason we disclose a kind of obstetrics and gynecology hemostatic bag which effectively solves the above problems.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figure 1-4, obstetrics and gynecology hemostatic sac includes uterine sac and vaginal sac 1; described uterine sac includes inner sac 2 and outer sac 3 sheathed on the outside of inner sac 2; inner sac 2 and outer sac 3 The front ends are all arc-shaped; the space between the inner capsule 2 and the outer capsule 3 is filled with a shear thickening fluid 4; inside the shear thickening fluid 4, an ultrasonic vibrator 5 is installed on the outer wall of the inner capsule 2; the outer wall of the outer capsule 3 is wrapped with a shockproof pad 6; anti-vibration pad 6 is wrapped with hemostatic cotton wool 7; the hemostatic cotton 7 is provided with a spray tube 8; spray holes 20 are evenly distributed on the spray tube 8; the entrance of the spray tube 8 is connected with a syringe 9; The rear end of the bag 2 is connected with an air inlet pipe 10 and a first air outlet pipe 11; a pressure gauge 12 is installed at the rear of the air inlet pipe 10; an air pump 13 is connected to the air inlet of the air inlet pipe 10; structure; the vaginal sac 1 is installed in the middle of the air intake pipe 10 and communicates with the air intake pipe 10; the vaginal sac 1 is communicated with a second air outlet pipe 14; the first air outlet pipe 11 and the second air outlet pipe 14 are equipped with air outlet valves 15; a pressure sensor 16 is installed on the outer wall of the vaginal sac 1; the signal output end of the pressure sensor 16 is connected to the processor; the processor is connected to the air pump 13; the auxiliary air bag 17 is evenly distributed outside the anti-vibration pad 6; the auxiliary air bag 17 is connected to a ventilation tube 18 The ventilation pipe 18 passes through the shockproof pad 6 and the outer bag 3, and communicates with the inner bag 2; a solenoid valve 19 is installed on the ventilation pipe 18.

When encountering uterine bleeding, the uterine sac and vaginal sac 1 have not been inflated and are in a contracted state, and the front ends of the outer sac 3 and the inner sac 2 are arc-shaped, which can be easily sent into the uterus through the vagina, while avoiding Contact the inner wall of the vagina; when the uterine sac reaches the uterus, turn on the air pump 13 to inflate the inner sac 2 and the vaginal sac 1 through the air inlet tube 10, and the vaginal sac 1 will bulge and fit the inner wall of the vagina. It can block the cervix and keep it fixed, which ensures the positioning of the utility model. Even if it is subjected to uterine contraction or external force, the uterine sac will not move in the uterus at this time. The inner wall is in contact with the bleeding part of the inner wall of the uterus, and then the ultrasonic vibrator 5 is turned on, and the ultrasonic vibrator 5 emits ultrasonic vibrations, and the shear thickening liquid 4 between the inner capsule 2 and the outer capsule 3 thickens and hardens rapidly, so that the shape of the uterine capsule remains fixed , to prevent deformation from affecting the compression effect, and then spray the medicine spraying tube 8 through the syringe 9, and the medicine is sprayed into the hemostatic cotton wool 7 through the spraying holes 20 evenly distributed on the medicine spraying tube 8, and the hemostatic cotton wool 7 is in contact with the uterine bleeding. The drug plays a role to achieve the purpose of hemostasis; in order to prevent the hemostatic cotton wool 7 from affecting the inflation and expansion effect of the uterine sac, the hemostatic cotton wool 7 can be set as a segmented structure; after the hemostasis is completed, the ultrasonic vibrator 5 is closed, the air outlet valve 15 is opened, the first air outlet pipe 11 and The second trachea 14 deflates, the uterine sac and the vaginal sac 1 shrink, and the utility model can be successfully taken out.

During the process of hemostasis, because the shear thickening liquid 4 maintains a hard state under the vibration of the ultrasonic vibrator 5, the shape of the inner bag 2 remains fixed, so the air inlet tube 10 cannot inflate the inner bag 2 at this time, and can only inflate the vaginal bag 1. Inflation, but in order to avoid continuous inflation causing excessive contact pressure between the vaginal sac 1 and the inner wall of the vagina and harming the patient, a pressure sensor 16 is set to detect the pressure of the contact between the vaginal sac 1 and the inner wall of the vagina. When the pressure reaches the set value, the pressure The sensor 16 controls the closing of the air bag through the processor AT89C2051-24PU, and stops inflation; a pressure gauge 12 is provided on the air intake pipe 10 to monitor the pressure in the uterine sac and the vaginal sac 1 at any time. , pulse and other conditions to adjust the pressure of the uterine sac and vaginal sac 1 on the inner wall of the uterus in time. If it is necessary to adjust the pressure of the uterine sac on the inner wall of the uterus, then turn off the ultrasonic vibrator 5, and the shear thickening liquid 4 will return to liquid state without being subjected to vibration , at this time, it is possible to inflate and pressurize through the air inlet pipe 10 or open the outlet valve 15 to deflate and depressurize through the first outlet pipe 11, and the same vaginal pouch 1 can also be inflated and pressurized through the inlet pipe 10 or to open the outlet valve 15 to pass through the second The air outlet pipe 14 is deflated and decompressed to achieve the purpose of regulation, and the pressure change can be visually observed through the pressure gauge 12 .

Wrap the anti-vibration pad 6 outside the outer bag 3 to absorb the ultrasonic vibrations sent by the ultrasonic vibrator 5 and prevent the ultrasonic vibration from harming the human body; an auxiliary air bag 17 is set outside the anti-vibration pad 6. The air tube 18 connected to the inner bag 2 can inflate the auxiliary airbag 17, and the inflation will stop when the solenoid valve 19 is closed. These auxiliary airbags 17 play a role in auxiliary compression. When compressing the inner wall of the uterus, there may be places where the hemostatic cotton wool 7 cannot touch At this time, inflate the auxiliary airbag 17 of the corresponding part, and the auxiliary airbag 17 is bulged, so that the hemostatic cotton wool 7 is in contact with the place, and the purpose of hemostasis is realized. The utility model can realize tighter compression on all parts of the inner wall of the uterus by setting the auxiliary airbag 17 , Increased the practicability of the utility model. When using the utility model, the observation means such as endoscope and B-ultrasound can be used to ensure the accuracy of operation.
