Built-in obstetric vaginal bleeding negative pressure drainage metering device

Abstract

The invention discloses a built-in obstetric vaginal bleeding negative pressure drainage metering device, which comprises a blood collector for receiving vaginal bleeding and a negative pressure drainage bag connected to the blood collector through a double-lumen tube; the device of the blood collector The wall is a double-layer hollow wall, and a sealed cavity is formed between the inner wall and the outer wall of the blood collector. The material of the blood collector is a flexible material; The drainage part of the drainage bag and the guide part for introducing sterile saline into the cavity; the built-in obstetric vaginal bleeding negative pressure drainage metering device can timely drain and collect vaginal bleeding during cesarean section and postpartum, and measure it accurately in real time The amount of bleeding can assist doctors to quickly and accurately judge the amount of intrapartum and postpartum hemorrhage, which is conducive to early detection and timely rescue of postpartum hemorrhage.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a built-in obstetric vaginal bleeding negative pressure drainage metering device. Background technique [0002] At present, intrapartum and postpartum hemorrhage have always been important factors that threaten the life and health of puerpera; in clinical practice, for cesarean section bleeding, in addition to accurate measurement of bleeding during abdominal surgery, for high-risk pregnant women such as placenta previa, During cesarean section with placenta accreta and dangerous placenta previa, the bleeding will flow out through the vagina to the buttocks and lower body of the pregnant woman under anesthesia in the supine position, and the amount of bleeding can only be determined by the assistant under the stage It is difficult to make accurate and timely judgments due to the rough estimation of the approximate wetted area of ​​the pad towel, thus delaying the rescue of blood tr...

[0002] At present, intrapartum and postpartum hemorrhage have always been important factors that threaten the life and health of puerpera; in clinical practice, for cesarean section bleeding, in addition to accurate measurement of bleeding during abdominal surgery, for high-risk pregnant women such as placenta previa, During cesarean section with placenta accreta and dangerous placenta previa, the bleeding will flow out through the vagina to the buttocks and lower body of the pregnant woman under anesthesia in the supine position, and the amount of bleeding can only be determined by the assistant under the stage It is difficult to make accurate and timely judgments due to the rough estimation of the approximate wetted area of ​​the pad towel, thus delaying the rescue of blood transfusion, changing the timing of the operation range, causing adverse maternal outcomes, and even the tragedy of maternal death; Blood may also accumulate in the vagina and lower uterine segment, resulting in a large amount of hemorrhage, which will affect postpartum uterine contraction and further induce bleeding
