Uterine cavity compression hemostatic balloon catheter and control system thereof

Abstract

The invention belongs to the field of medical instruments, and relates to a uterine cavity compression hemostatic balloon catheter and a control system thereof. According to the uterine cavity compression hemostasis balloon catheter, a balloon and a balloon catheter are both provided with imaging rubber strips, so that doctors can quickly track and position the displacement of the catheter in a vagina and a uterine cavity at any time, and the operation is convenient and fast; after the balloon is inflated, the balloon is in an inverted pear shape, and in the balloon inflation process, exuded blood can be smoothly discharged out of the uterine cavity from a catheter drainage cavity and an outer surface of the balloon, so that blood clots are prevented from hindering the balloon to adhere tothe uterine wall, which influences the hemostatic effect. The uterine cavity compression hemostaticballoon catheter control system has the advantages of automatic control, safety monitoring and simple operation, can more intelligently and scientifically control the capacity of the balloon, ensures that the balloon can be tightly attached to the uterine cavity, and has a good hemostatic effect; the uterine cavity compression hemostatic balloon catheter can rapidly and accurately position, track and monitor safety.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a uterine cavity compression hemostatic balloon catheter and a control system thereof. Background technique [0002] There is an urgent need for a simple, safe and effective hemostatic device in obstetrics. Postpartum hemorrhage refers to the bleeding volume of 500ml or more within 24 hours after delivery of the fetus. It is the most common clinical manifestation of obstetric hemostasis disorder and the main cause of increased obstetric complications and maternal death. The number one cause of death among pregnant women in my country is postpartum hemorrhage, which accounts for more than 1 / 3 of the number of deaths among pregnant women. Moreover, the primary cause of postpartum hemorrhage is uterine atony, and the drug treatment effect of some refractory uterine fibroids is extremely poor. Because intrauterine bleeding has the characteristics of diffuse bleeding points and the in...

AI Technical Summary

Problems solved by technology

The main defects of these balloon compression hemostasis in clinical application are as follows: first, the water bladder made by binding has uneven dead corners, and the capacity of the water bladder is not enough and cannot be adjusted, so it is difficult to effectively and safely compress the entire uterine cavity to achieve hemostasis; Second, if the intrauterine bleeding continues to occur, and the uterine ostium is compressed by the balloon and cannot be drained, it will lead to hemorrhage in the uterine cavity, and clinicians cannot judge the amount of bleeding, delaying clinical treatment

[0010] This patent does not involve balloon catheters, and only monitors the dual balloons through the pressure sensor of the water injection / discharge interface, which may result in inaccurate control of the balloon volume
