A method of uterine hemostasis involves inserting a suction line of a postpartum hemorrhage mitigation device through a cesarian incision into the uterine cavity, guiding the suction line through the cervix and into the vagina, positioning an anchoring mechanism of the device adjacent the internal cervical OS of the uterine cavity, closing the cesarian incision to enclose the suction line within the uterine cavity, and connecting the suction line to a negative pressure source that introduces negative pressure to the uterine cavity via the suction line, thereby causing contraction of the uterus and evacuation of fluid from the uterus via the suction line extension. Upon completion of a treatment period, the negative pressure source is disconnected, and the suction line and anchoring mechanism are extracted from the uterus through the cervical canal and the vagina.

This invention discloses a seamless switching medical simulation training system that integrates virtual and real-world childbirth and postpartum hemorrhage scenarios. Its features include: a maternal model, a childbirth simulation mechanism, and a postpartum simulation mechanism, one of which can be selectively mounted on the maternal model; the childbirth model mechanism includes an infant model, a birthing belly component, a birthing vagina component, and a drive device. The drive device is located within the maternal model, and the infant model is mounted on the drive device, allowing the drive device to move the infant model linearly and rotate towards the birthing vagina component; the birthing belly component is equipped with undulating components; this system achieves seamless switching between childbirth and postpartum hemorrhage scenarios through a modular and detachable structure, realistically simulating clinical scenarios such as the childbirth process and postpartum hemorrhage care. It is comprehensive in function, realistic in operation, and can effectively improve the standardized operation and emergency response capabilities of medical personnel.

The application discloses a seamless switching type medical simulation training system for childbirth and postpartum hemorrhage deficiency and excess fusion, and has the characteristics that the system comprises a puerpera model, a childbirth simulation mechanism and a postpartum simulation mechanism, the childbirth simulation mechanism and the postpartum simulation mechanism can be selectively assembled on the puerpera model; the childbirth model mechanism comprises a baby model, a childbirth belly component, a childbirth vaginal component and a driving device, the driving device is arranged in the puerpera model, the baby model is arranged on the driving device, and the baby model is driven by the driving device to realize linear movement and rotary motion in the direction of the childbirth vaginal component; the childbirth belly component is internally assembled with a fluctuation component; the system realizes seamless switching of childbirth and postpartum hemorrhage scenes through a modular detachable structure, can truly simulate clinical scenes such as a childbirth process and postpartum hemorrhage nursing, is comprehensive in function, real in operation, and can effectively improve the standard operation and emergency disposal ability of medical staff.

The invention discloses an intelligent lochia nursing pad for postpartum hemorrhage monitoring and an early warning system, and relates to the technical field of physiological monitoring. The intelligent lochia nursing pad early warning system comprises a diffusion time phase construction module, a potential reversal recognition module, a phase dislocation analysis module, an anti-reversal time grating generation module and a reverse diffusion traction regulation and control module. The intelligent lochia nursing pad for postpartum hemorrhage monitoring comprises the early warning system. According to the invention, by establishing a diffusion time phase recording chain and introducing potential inversion identification, phase dislocation analysis and time grating traction regulation and control mechanisms, space-time synchronization of flexible sensing node response is realized, signal inversion and disorder are avoided, continuous increasing of a bleeding amount curve is maintained, negative sudden change is inhibited, and the stability and reliability of an early warning signal are improved. And accurate real-time monitoring of postpartum hemorrhage is realized.
