Built-in negative pressure drainage metering device for obstetric vaginal bleeding

Abstract

The invention discloses a built-in negative pressure drainage metering device for obstetric vaginal bleeding, and belongs to the field of medical instruments. The device comprises a main body, whereina rotating shaft is fixedly installed at the middle section of the main body; a cleaning frame A and a cleaning frame B are fixedly installed in the left and right sides of the main body; a catheterA and a catheter B are detachably connected to the outer sides of the cleaning frame A and the cleaning frame B respectively; a flow guide pipe is detachably installed in a negative pressure catheter;a blood box is detachably connected to the other end of the flow guide pipe; and a grip strength air bag is connected to the outer side of the negative pressure catheter in an embedded mode. Accordingly, by installing the main body, the rotating shaft, a contraction cavity, a sliding device, a spring, a contraction roller, a contraction rope, the cleaning frame A, the cleaning frame B, the catheter A, the catheter B, a collecting cavity, a blocking curtain, the negative pressure catheter, the grip strength air bag and the blood box, the device can be suitable for pregnant women of different constitutions to use, meanwhile, bleeding in the bodies of the pregnant women can be discharged rapidly, the bleeding amount can be measured rapidly, and the using effect is improved.

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...

AI Technical Summary

Problems solved by technology

[0004] The device has the following disadvantages in use: 1. The device cannot sterilize the body of pregnant women with physiological saline, which is not safe and hygienic, and cannot meet the needs of vaginas of different sizes, so it needs to be improved; 2. The device When using it, it is impossible to quickly and timely remove the bleeding inside the pregnant woman's body, and it is impossible to judge the amount of bleeding in a timely and accurate manner, so the practicability is poor
