Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically to a hemostatic balloon for uterine cavity. Background Art

[0002] The uterine cavity is the space of the uterus, also called the uterus. The uterus is a single muscular organ. During normal delivery, the mother's body has a perfect self-hemostatic function, including strong contraction of the uterus to compress the capillaries in the placenta and fetal membrane detachment wound in the cavity. The body's coagulation system is activated and works together to play a hemostatic role. When the above two self-hemostatic functions are destroyed, excessive postpartum bleeding may occur. Intrauterine balloon compression is a conservative treatment method for postpartum hemorrhage. Water is injected into the balloon to make the balloon continue to expand, thereby forming a compression effect on the blood vessels at the bleeding site, thereby achieving the hemostatic function.

[0003] In the existing hemostasis technology, an anti-blocking structure is set up, and a plastic pull rope is used to pass through the guide tube and the inside of the blood guide groove in sequence and fixedly connected to one end of the retaining groove. When blood stasis blocks the blood guide groove, the retaining groove is inserted into the blood guide groove by pulling and pulling the plastic pull rope, and the blood stasis condensed in the blood guide groove is squeezed and broken, so that the blood stasis can flow into the inside of the main guide tube through the blood guide groove and be discharged from the blood drainage tube, thereby preventing the discharge of blood stasis from being blocked. However, in this process, the plastic pull rope runs through the inside of the blood guide groove. Although it can clear the blocked blood stasis, the introduction of the plastic pull rope also shrinks the blood guide groove, hindering the discharge of blood stasis. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hemostatic balloon for the uterine cavity which can effectively clear the blocked blood stasis and does not hinder the discharge of the blood stasis.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Furthermore, a first connecting pipe and a second connecting pipe are provided in the main conduit, and an inner wall of one end of the main conduit is sealedly connected to an outer wall of the drainage pipe.

[0008] Furthermore, one end of the first connecting tube passes through the tube wall of the main tube and is connected to the balloon body, and the other end of the first connecting tube is connected to an energy supply device.
