Blood collector for postpartum hemorrhage

Abstract

The utility model relates to the technical field of obstetrical auxiliary tools, and discloses a blood collector for postpartum hemorrhage, which comprises a cup body, the surface of the cup body is sleeved with an anti-overflow component, the bottom end of the cup body is communicated and connected with a pipeline A, the bottom end of the pipeline A is communicated and connected with an operation pipe, and the operation pipe is connected with a pipeline B; and the interior of the operation pipe is fixedly connected with an anti-reflux assembly. According to the blood collector for postpartum hemorrhage, through the arrangement of the anti-backflow assembly, when blood flows in the direction from a pipeline A to an operation pipe, the blood can eject a flow limiting ball open, due to the fact that a gap exists between the flow limiting ball and the inner wall of the operation pipe, the blood can flow out through the operation pipe, and when the blood flows in the reverse direction, a spring pushes the flow limiting ball to a blocking ring, and the flow limiting ball is blocked; the blocking ring just clamps the flow limiting ball, so that the pipeline space is blocked, blood cannot pass through the pipeline space, the blood cannot flow back to the wound, and the risk that the wound is polluted by backflow objects and then infected is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of obstetric auxiliary tools, in particular to a blood collector for postpartum hemorrhage. Background Art

[0002] Bleeding of more than 500 mL within 24 hours after the birth of the fetus is called postpartum hemorrhage. Postpartum hemorrhage is a serious complication during delivery and one of the four major causes of maternal death. In recent years, postpartum hemorrhage has been the leading cause of maternal death in my country. Due to the large subjective factors in measuring and collecting the amount of bleeding, the actual incidence rate is higher. Postpartum hemorrhage often occurs within 2 hours after the birth of the fetus, and can occur before, after, or both before and after the birth of the placenta. Vaginal bleeding can be heavy bleeding in a short period of time, or it can continue for a long time with a small amount of bleeding. It is generally overt, but there are also occult bleeding. Pregnant women will use a blood collector when they have postpartum hemorrhage. The main purpose of the blood collector is to collect lost blood for further examination, analysis or treatment. This can help doctors assess the patient's condition and determine whether further treatment measures are needed, such as blood transfusion, drug treatment or surgery.

[0003] Existing blood collectors for postpartum hemorrhage cannot prevent blood from flowing backward during delivery when used in practice, which can easily lead to contaminated blood carrying bacteria flowing backward into the uterine cavity of the parturient when the parturient changes her body position, causing infection.

[0004] After searching the existing patents: a blood collector for postpartum hemorrhage (publication number: CN220256853U), including a cup body, an air bag is arranged on the surface of the cup body, a flexible catheter is fixedly connected to the lower surface of the cup body, a bleeding port is opened on the lower surface of the cup body, one end of the flexible catheter is fixedly connected to a buffer box, a hard catheter is fixedly connected to the buffer box, one end of the hard catheter is fixedly connected to a connector, a connecting pipe is threadedly connected to the connector, and a replacement component is arranged on the buffer box. The blood collector for postpartum hemorrhage is provided with a replacement component. When the blood bag needs to be replaced, the adjustment plate is rotated, and the adjustment plate drives the threaded rod to rotate, so that the extrusion plate moves toward the limit plate. The hard catheter is clamped by the mutual cooperation of the extrusion plate and the limit plate to prevent blood from flowing into the connecting pipe. The internal thread and the external thread are rotated to disengage the lock, which is convenient for the replacement of the blood bag and improves practicality.

[0005] Although the above patent makes it easy to replace the blood bag, blood is easy to overflow during use, making it inconvenient to adapt to different patients.

[0006] Therefore, it is necessary to invent a blood collector for postpartum hemorrhage to solve the above problems. Utility Model Content

[0007] 1. Technical issues to be solved

[0010] To achieve the above objectives, the utility model is implemented through the following technical solutions: a blood collector for postpartum hemorrhage, comprising a cup body, the surface of the cup body is sleeved with an anti-leakage component, the bottom end of the cup body is through-connected with a pipe A, the bottom end of the pipe A is through-connected with an operating tube, the inside of the operating tube is fixedly connected with an anti-backflow component, the bottom end of the operating tube is fixedly connected with a rubber ring, the bottom of the rubber ring is fixedly connected with an elastic tube, the bottom end of the elastic tube is fixedly connected with a connecting ring, the inner wall of the connecting ring is threadedly connected with a picking component, and the bottom end of the picking component is fixedly connected with a receiving bag.

[0011] As a further solution of the utility model, the anti-leakage component includes an airbag layer sleeved on the surface of the cup body, and an elastic gasket is fixedly connected to the surface of the airbag layer, which facilitates sealing and fitting.

[0012] As a further solution of the utility model, the bottom end of the airbag layer is fixedly connected to an inflation tube, one end of the inflation tube is fixedly connected to a hand-pinch airbag, one end of the hand-pinch airbag is fixedly connected to an exhaust knob, and the exhaust knob is convenient for storing air.

[0013] As a further solution of the utility model, the anti-backflow component includes a positioning ring fixedly connected to the inside of the operating tube, and a spring is fixedly connected to the top end of the positioning ring to facilitate rebound.

[0014] As a further solution of the utility model, the top of the spring is fixedly connected to a flow-limiting ball, and the bottom of the inner wall of the pipeline A is fixedly connected to a blocking ring, which facilitates sealing the flow-limiting ball.

[0015] As a further solution of the utility model, a sealing ring pad is sleeved on the surface of the picking assembly, and a soft ring is fixedly connected to the top of the cup body, and the soft ring increases comfort and reduces damage.

[0016] (III) Beneficial effects

[0017] The utility model provides a blood collector for postpartum hemorrhage, which has the following beneficial effects:

[0018] 1. The blood collector for postpartum hemorrhage is provided with an anti-leakage component. When in use, according to the size of the patient's postpartum cervix, the airbag layer is inflated by squeezing the airbag to make the airbag swell and block the gap around the cervix. The elastic sealing pad can fit the surface of the tissue to increase stability and sealing. After determining the inflation amount, the exhaust knob is tightened to seal gas leakage, thereby achieving adaptation for postpartum hemorrhage collection for different patients, avoiding the overflow of blood on the medical staff due to a large cervix during operation, causing pollution, and improving the safety of blood collection.

[0019] 2. The blood collector for postpartum hemorrhage has an anti-backflow component. When blood flows from pipeline A to the operating tube, the blood will push the flow-limiting ball open. Since there is a gap between the flow-limiting ball and the inner wall of the operating tube, the blood can flow out through the operating tube. When the blood flows in the opposite direction, the spring pushes the flow-limiting ball to the blocking ring. The blocking ring just catches the flow-limiting ball, so that the pipeline space is blocked and blood cannot pass through. This ensures that blood will not flow back to the wound, thus avoiding the risk of the wound being contaminated by reflux and then infected. BRIEF DESCRIPTION OF THE DRAWINGS
