[0002] At present, intrapartum and postpartum hemorrhage has always been an important factor threatening the life, health and safety of parturients. In clinical practice, for bleeding during cesarean section, in addition to accurate measurement of bleeding during abdominal surgery, during cesarean section for high-risk pregnant women such as placenta previa, placenta accreta, and pernicious placenta previa, bleeding flows out through the vagina to the buttocks and lower body of the pregnant woman in a supine position and anesthesia. The amount of bleeding can only be roughly estimated by the assistants below the stage based on the approximate soaking area of ​​the towel under the pregnant woman. It is impossible to make an accurate and timely judgment, thus delaying the timing of blood transfusion and rescue, changing the scope of surgery, resulting in adverse maternal outcomes, and even the tragedy of maternal death. At the same time, blood flowing out through the cervix may also accumulate in the vagina and lower uterus, resulting in a large amount of blood accumulation, thereby affecting postpartum uterine contraction and further inducing bleeding.

[0027] A quantifiable drainage bag, such as Figure 1-7As shown, it includes: a collecting pool, a drainage tube, a measuring bag and a deformable eaves; the collecting pool is made of flexible material, the collecting pool is a wide-mouth container, the upper edge of the collecting pool is fixedly connected to the deformable eaves, the deformable eaves are rigid materials that are easy to deform, the bottom of the collecting pool is fixedly connected to the drainage tube, and a through hole is opened at the bottom of the collecting pool, the shape and size of the through hole are adapted to the cross-section of the drainage tube, the other end of the drainage tube is fixedly connected to the measuring bag, and the collecting pool is connected to the measuring bag through the drainage tube; the deformable eaves can be adjusted at will according to the shape of the opening of the delivery bed, so that the drainage bag can be conveniently fixed on the delivery bed, and the situation of falling off during use is greatly reduced, the drainage tube guides the liquid in the collecting pool to the measuring bag, so as to accurately measure the amount of bleeding of the parturient, thereby ensuring the safety of the parturient, the drainage bag is relatively simple in structure, and the manufacturing and use costs are relatively low, which reduces the treatment burden for patients and is conducive to popularization and use.

[0028] Furthermore, a hook is provided at the upper end of the measuring bag, and the hook is fixedly connected to the measuring bag; the function of the hook is to conveniently fix the measuring bag in a suitable position, so that the doctor can observe the liquid level in the measuring bag conveniently.

[0029] Furthermore, the drainage bag also includes a drainage tube, a switch cap and a cut-off assembly; the drainage tube is a hollow tubular structure, a through hole is opened at the bottom of the metering bag, the shape and size of the through hole are adapted to the cross-section of the drainage tube, the drainage tube is fixedly connected to the opening at the bottom of the metering bag, the switch cap is detachably fixedly connected to the other end of the drainage tube, the connection method of the switch cap to the drainage tube is preferably a threaded connection, and the cut-off assembly is arranged on the outer wall of the drainage tube; the function of the cut-off assembly is that when the amount of bleeding is large, the excessive liquid in the metering bag needs to be drained out, the switch cap is removed, and the liquid in the drainage bag is drained out When the blood is discharged through the diversion tube, the interception component can temporarily intercept the liquid in the collection pool so that it cannot flow into the measuring bag temporarily, thereby avoiding the problem that the liquid in the measuring bag is discharged and flows in at the same time, and the measurement cannot be accurate. When the drainage of the liquid in the measuring bag is completed, the interception component is released, so that the liquid continues to flow into the measuring bag, and the amount of bleeding continues to be measured, which further facilitates the use. Even when the amount of bleeding is large, there is no need to replace a new drainage bag. The liquid only needs to be discharged through the diversion tube, which saves resources, reduces costs, and further improves the accuracy of measurement.

[0030] Among them, the intercepting component includes two clips, which are rectangular sheet structures. The two clips are arranged opposite to each other, one end of the two clips is hinged, and the other end is provided with a fixed structure, and the fixed structure is preferably a magnetic buckle; the intercepting component adopts the form of a clip, and the structure is simple to achieve the purpose of interception, saving manufacturing costs.

Preferably, the hinge axis between the two clips is slidably connected to the slide rail; the clip is slidably connected to the slide rail, which not only plays a role in intercepting the flow, but also can squeeze the liquid hanging on the wall of the drainage tube into the measuring bag, thereby further improving the accuracy of the measurement.

[0032] Among them, the bottom of the collection pool is a funnel-shaped structure, such as Figure 1 , Figure 2 As shown, the funnel structure helps the liquid to flow into the drainage tube more smoothly.

[0033] The deformable eaves include a shell layer and a deformable rib; the shell layer is made of a flexible material and is wrapped around the outer surface of the deformable rib. Figure 7 As shown, the shell layer is fixedly connected to the upper end of the collection tank, and the deformable ribs are rigid materials that are easy to deform, preferably aluminum wire or low-strength steel wire.

[0034] Preferably, the collection pool and the drainage tube are made of polyethylene or polypropylene plastic film, and the measuring bag is made of medical soft transparent SEBS material.

[0035] When in use, the deformable eaves are bent according to the opening shape of the delivery bed, the measuring bag is installed on the delivery bed, and the liquid collected in the collection pool flows into the measuring bag through the drainage tube. The measuring bag is fixed in a suitable position by a hook for easy observation. When there is too much liquid in the measuring bag, the clip is fastened by the magnetic buckle, clamping the drainage tube and sliding from the top of the drainage tube to the bottom of the drainage tube, temporarily intercepting the liquid to the top of the measuring bag, opening the switch cap, and the liquid in the measuring bag is discharged through the diversion tube. After the discharge is completed, the switch cap is closed, the clip is opened, and the measuring is continued.
