Blood collector for postpartum hemorrhage

Abstract

The invention relates to a blood collector for postpartum hemorrhage. The blood collector comprises an air bag, an inflation pump, a communicating pipe, a negative-pressure suction tube, a blood storage bag and at least two pressure alarm devices, wherein the upper surface of the air bag is in an arch shape, the lower surface of the air bag is provided with a fixing part capable of reducing and increasing the inner diameter of a corresponding part, the upper surface of the air bag is provided with an inner cavity which is concave towards the interior of the air bag and runs through the fixingpart, and a supporting part is arranged on the portion, on the peripheral side of the inner cavity, on the upper surface of the air bag; the inflation pump is connected with the air bag and is used for inflating the air bag; one end of the communicating pipe is inserted into the fixing part to the inner cavity and is fixed through the fixing part; the negative-pressure suction tube is integrated with the communicating pipe and communicated with the communicating pipe; the blood storage bag is provided with a control valve connecting pipe, and the two ends of the blood storage bag are connectedwith the communicating pipe and the blood storage bag respectively; the pressure alarm devices are arranged on the supporting part of the air bag and on the outer surface of the blood storage bag respectively. According to the blood collector, blood of postpartum hemorrhage can be accurately collected, the early warning function is achieved, medical staff do not need to bend over and check, and blood blockage cannot be caused.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood collector for postpartum hemorrhage. Background technique [0002] Postpartum hemorrhage is defined as bleeding exceeding 500 mL within 24 hours after delivery of the fetus. Postpartum hemorrhage is a serious complication during childbirth and one of the four major causes of maternal death. In my country, postpartum hemorrhage has always been the number one cause of maternal death in recent years. Due to the large subjective factors in measuring and collecting the amount of bleeding, the actual incidence rate is higher. Postpartum hemorrhage mostly occurs within 2 hours after the fetus is delivered. Before, after, or both after delivery of the placenta. Vaginal bleeding can be heavy bleeding in the short term, or it can last in a small amount for a long time. Generally dominant, but there are also occult bleeding. [0003] The clinical manifestations are mainly vagina...

Problems solved by technology

[0004] For example, in the Chinese patent with the application number: 201320100989.4, a postpartum hemorrhage collection device is mentioned, which includes a U-shaped holder and an elastic sleeve, and a drainage groove is provided at the lower end of the U-shaped holder, and a tray is provided at the lower end of the drainage groove. When in use, The U-shaped support is placed on the perineum of the parturient and fixed on the leg with an elastic sleeve. The blood flows directly into the tray along the drainage groove for collection. However, it is impossible to estimate the amount of blood collected by this method, requiring medical staff to bend over from time to time. Check the blood condition in the tray, if there is no warning function, if there is too much blood flowing out, it will cause the life-threatening of the parturient, and the blood collected by this method often contains urine or other foreign objects, which makes the amount of blood collected Inaccurate

[0005] For example, in the Chinese patent with the application number: 201721451029.7, a postpartum hemorrhage measurement and alarm device applied on the delivery bed is recorded. The device adds an alarm device and reduces the number of medical staff leaning over to observe the amount of bleeding, but still requires medical care. leaning over observation
