intrauterine compression balloon

Abstract

The invention discloses an intrauterine compression balloon, which comprises a conduit, and a main balloon and a subordinate balloon which sleeve the conduit, and further comprises a drainage tube, wherein main balloon and subordinate balloon water injection passages and a first drainage passage are formed in the conduit; an opening part is formed in the main balloon; one end of the conduit extends into the main balloon in a sealed mode from the opening part; the outer wall of the main balloon extends inwards, so that a drainage part is formed; the drainage part is provided with a second drainage passage which communicates with the first drainage passage; and one end of the drainage tube penetrates through the first drainage passage and the second drainage passage and extends into a uterine cavity when the drainage tube is used. A uterine cavity form, which is similar to the structure of a uterine cavity, is shaped as the main balloon is injected with water and becomes swelled, so that a better effect of homeostasis by compression is achieved. By arranging a pressure sensor inside the main balloon, the compression balloon is convenient for a doctor to perform treatment, so as to avoid unnecessary pain in a patient due to excessive pressure.

Description

technical field [0001] The invention relates to a uterine cavity compression balloon, which belongs to the field of medical instruments. Background technique [0002] Postpartum hemorrhage is a serious complication during childbirth, and it is the first of the four major causes of maternal death. The treatment of postpartum hemorrhage is usually urgent and difficult. The most common cause of postpartum hemorrhage is uterine atony. This type of bleeding has the characteristics of rapid bleeding, large amount of bleeding, diffuse bleeding points, difficulty in exposure, and inability to stop bleeding under direct vision. If conventional conservative hemostasis fails, emergency hysterectomy is required. It caused the regret of the patient's organ loss and lifelong infertility. In recent years, intrauterine balloon compression has gradually become an alternative solution for postpartum hemorrhage. By injecting water into the balloon to make the balloon continuously expand, it c...

AI Technical Summary

Problems solved by technology

Due to the morphological characteristics of the existing balloon and the structural characteristics of the guide tube passing through the main balloon, the main balloon cannot fit well with the inner wall of the uterine cavity after being inflated with water, and the force on the inner wall of the uterine cavity is uneven, and some inner walls of the uterine cavity Not being compressed, thus not having a good hemostatic effect

In addition, the water pressure in the balloon cannot be accurately measured after the balloon is filled with water. At the same time, the compression force of the inner wall of the uterine cavity cannot be measured after the patient's uterine contractility recovers, so the balloon cannot be decompressed in time, causing huge physical and mental damage to the patient. Painful, but also brings great inconvenience to the doctor's treatment and prognosis
