Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a blood collection device for cesarean section. Background Art

[0002] The scarred uterus is prone to uterine rupture, which refers to the rupture of the uterine body or lower uterine segment during pregnancy or delivery. Uterine rupture often leads to heavy bleeding, and placenta previa is also prone to postpartum hemorrhage, which can cause a series of complications such as hemorrhagic shock, disseminated intravascular coagulation (DIC), ischemic hypoxic encephalopathy, pulmonary edema, and Sheehan syndrome. In mild cases, the patient needs hysterectomy, and in severe cases, death occurs. When bleeding occurs during cesarean section, it is often necessary to measure the amount of bleeding to further evaluate the condition. The Chinese utility model patent with announcement number CN218500953U discloses "a device for collecting bleeding during cesarean section", which includes a collection bag, a connection seat fixedly connected to the upper surface of the collection bag, a groove provided on the upper surface of the connection seat, a first piston plate slidingly arranged in the groove, a connecting rod fixedly connected to the upper surface of the first piston plate, one end of the connecting rod fixedly connected to the second piston plate, a placement groove provided on the upper surface of the second piston plate, a connector plugged into the placement groove, an opening provided on the lower surface of the second piston plate, a through groove provided on the inner wall of the groove, a drainage tube connected to the upper end of the connector, and a collection bucket connected to one end of the drainage tube. The bleeding amount in the uterine cavity can be effectively collected through the cooperation among the collection bag, the connection seat, the groove, the first piston plate, the connecting rod, the second piston plate, the placement groove, the connector, the opening, the through groove, the drainage tube and the collection bucket, so as to not destroy the sterile environment during cesarean section and accurately assess the bleeding amount. However, the above-mentioned collection device has the following problems when in use:

[0003] It uses drainage tubes to connect and accumulate bleeding, but the drainage tubes are relatively long and may get stuck to the wall. When bleeding is severe, the small drainage tubes may be blocked and cannot drain quickly. Without careful observation, it is impossible to know that the drainage tubes are blocked. The above situations often lead to medical staff being unable to quickly determine the amount of bleeding. Therefore, how to achieve rapid drainage during bleeding and timely alarm in case of blockage is an urgent problem to be solved. Summary of the invention

[0021] like Figure 1 to Figure 2As shown, a preferred embodiment of the utility model provides a blood collecting device for cesarean section surgery, including a mounting plate 1 and a blood collecting piece 2, the mounting plate 1 is provided with a mounting hole 11; the blood collecting piece 2 includes an open-mouth ring 21, a funnel collecting tube 22 and a liquid storage bottle 23, the open-mouth ring 21 is detachably clamped on one side of the mounting hole 11, the funnel collecting tube 22 is detachably provided with the mounting hole 11, and the wide-mouth end of the funnel collecting tube 22 is connected to the open-mouth ring 21; the liquid storage bottle 23 is connected to the narrow-mouth end of the funnel collecting tube 22 and extends to the outside of the mounting plate 1, and a scale line 233 is provided on the liquid storage bottle 23.

[0022] When using the above-mentioned blood collection device for cesarean section, the mounting plate 1 is placed under the patient's crotch, the open-end ring 21 is clamped on the side of the mounting hole 11 facing the patient and the open-end ring 21 is made to correspond to the patient's vaginal opening. When heavy bleeding occurs, the blood flows directly from the open-end ring 21 into the funnel collecting tube 22, and the blood is quickly collected through the funnel collecting tube 22 and directed to the liquid storage bottle 23 for collection. The operator can intuitively and quickly read the collected blood volume from the scale line 233. It can be seen that because the funnel collecting tube 22 and the liquid storage bottle 23 have a larger temporary storage space than the drainage tube in the prior art, the blood flow is quickly collected in the funnel collecting tube 22 and the liquid storage bottle 23 when the amount of bleeding is large, thereby realizing rapid drainage of the blood flow.

[0023] In this embodiment, the open-end ring 21 includes a ring body 211 and a snap-on step 212. The inner diameter of the ring body 211 is larger than the inner diameter of the mounting hole 11. The snap-on step 212 is connected to the ring body 211. The outer diameter of the snap-on step 212 is consistent with the inner diameter of the mounting hole 11, so that when the snap-on step 212 is inserted into the mounting hole 11, the ring body 211 is snap-on to the side of the mounting plate 1 corresponding to the mounting hole 11.

[0024] In this embodiment, the inner wall of the clamping step 212 is provided with an internal thread, and the outer surface of the funnel collecting tube 22 corresponding to the internal thread is provided with an external thread 220, so that the funnel collecting tube 22 and the clamping step 212 can be connected by screwing the internal thread and the external thread 220. The inner diameter of the funnel collecting tube 22 gradually decreases in the direction away from the external thread 220, so that a wide end is formed at the end of the funnel collecting tube 22 connected to the clamping step 212, and a narrow end is formed at the end of the funnel collecting tube 22 away from the clamping step 212. The funnel shape of the funnel collecting tube 22 enables the funnel collecting tube 22 to instantly receive a large amount of blood flow.

[0025] In this embodiment, the liquid storage bottle 23 includes a wide-mouth tube body 231 and a bottle body 232. The wide-mouth tube body 231 is connected to the narrow end of the funnel collecting tube 22 and extends to the outside of the mounting plate 1. The length of the wide-mouth tube body 231 is the sum of the thickness of the mounting plate 1 and the thickness of the bed plate. The bottle body 232 is connected to the end of the wide-mouth tube body 231 away from the funnel collecting tube 22; and a scale line 233 is provided on the bottle body 232. The length of the wide-mouth tube body 231 is shorter than that of the drainage tube in the prior art, which can further reduce the occurrence of blockage.

[0026] In this embodiment, a flow detection valve 3 is inserted into the bottle body 232, and an alarm 4 is overlapped and connected to one side of the inner part of the flow detection valve 3. When the flow detection valve 3 detects that the blood flow is too large or too small, it can be linked to the alarm 4 to alarm, so as to facilitate the operator to handle it, thereby increasing the safety of blood flow monitoring.

[0027] In this embodiment, a hook block 5 is provided on the side of the mounting plate 1 , and the hook block 5 can be provided for an operator to hang surgical supplies.
