Built-in negative-pressure drainage metering device for blood discharged from vagina for obstetrical department

Abstract

The invention discloses a built-in negative-pressure drainage metering device for blood discharged from vagina for obstetrical department. The device comprises a blood collecting device for receiving blood discharged from vagina and a negative-pressure drainage bag connected with the blood collecting device by a dual-cavity pipe. The wall of the blood collecting device is a dual-layer hollow wall; and a sealed cavity is formed between the inner wall and the outer wall of the blood collecting device. The blood collecting device is made of a flexible material. The dual-cavity pipe includes a drainage part for draining the blood in the blood collecting device to the negative-pressure drainage bag and a guiding part for guiding a stroke-physiological saline solution into the cavity. According to the built-in negative-pressure drainage metering device disclosed by the invention, timely drainage and collection of blood discharged from vagina during operation of the cesarean section and blood discharged from vagina after delivery can be realized; the bleeding amount is measured accurately in real time; and a doctor can be assisted in determining an intrapartum or postpartum bleeding amount rapidly and accurately, so that early-stage discovering and timely rescue for postpartum hemorrhage can be realized well.

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...
