Uterus occlusion balloon

Abstract

The invention relates to the field of medical instruments, in particular to a uterus occlusion balloon. The uterus occlusion balloon comprises a double-cavity catheter and a balloon body, an input cavity channel and an output cavity channel are concentrically arranged in the double-cavity catheter, the inner diameter of the input cavity channel is 0.05-0.5 mm larger than that of the output cavitychannel, and the output cavity channel penetrates through the balloon body and extends out of the balloon body. The uterus occlusion balloon is adopted, the uterine cavity passes through an open inletin the top end of the output flow channel; efflow inlet is increased, when bleeding and the like occur in the uterine cavity, the bleeding can be directly discharged; the hemostasis condition of theendometrial cavity can be conveniently and visually judged through a through hole, and the indwelling time is determined; in addition, the improved balloon can be used for carrying medicine, so that the mode of delivering medicine through an output cavity in an operation can be directly avoided or reduced when massive hemorrhage is treated, the stimulation to the uterine cavity membrane is reduced, the treatment time is shortened, and the pain of a patient is relieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and more specifically, the invention relates to a uterine blocking balloon. Background technique [0002] In the clinical process, parturients are prone to bleeding after delivery. Postpartum hemorrhage is the most important cause of maternal death worldwide. The most common cause of death is excessive blood loss, and more than half of maternal deaths occur within 24 hours of delivery. Worldwide, an estimated 140,000 women die each year from postpartum hemorrhage. In addition, postpartum hemorrhage may cause subsequent serious complications, the sequelae of which include adult respiratory distress syndrome, coagulopathy, shock, loss of reproductive function, and pituitary gland necrosis. [0003] In order to prevent postpartum hemorrhage, a balloon catheter or a balloon uterine stent is usually placed immediately after surgery to reduce postoperative bleeding. However, because the shape of the ...

AI Technical Summary

Problems solved by technology

However, because the shape of the catheter balloon is inconsistent with the uterus, the balloon cannot reach the uterine horn, so it cannot isolate the adhesion of the uterine horn, and it is easy to fall off

At present, although there are balloon uterine stents on the market that conform to the shape of the uterus, most of them are single-channel, which cannot observe intrauterine bleeding and drainage, and can only play an isolation role. The palace needs to be expanded to above the number "7", and it is very difficult to place and locate

In addition, the balloon part of both the urinary catheter and the balloon uterine stent is smooth. If the balloon is placed for too long, it may affect the blood circulation of the endometrium, which is not conducive to the healing of the surgical wound; Deformation, the diameter increases significantly, causing the balloon to be overstretched during the treatment and affect the operation
