Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to field of medical and surgical procedures device. More particularly, it relates to a device for controlling intrauterine pressure during surgical procedures such as hysteroscopy.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Hysteroscopy is a process by which we visualize inside the uterine cavity with a telescope system's help. Added benefit of the hysteroscopy process is that we can visualize the vaginal canal and the cervical canal. Hysteroscopy is not only for the diagnosis of vaginal, cervical, and uterine pathology but can also be used for the therapeutic process. Hysteroscopy can also be used to detect and treat other uterine pathology like uterine developmental anomalies, foreign body, isthmocele, A-V malformation, etc. Hysteroscopy can also be used to treat many conditions like sub-mucosal fibroid, polyp, uterine synechiae, removal of foreign body, septal resection, etc.
[0004] There can be three component involved in the process of hysteroscopy. First can be Telescope system (includes hysteroscope, camera, and light system), second can be distension media that passes through inlet channel of the hysteroscope and help in visualization of intrauterine structures and third can be most critical factor to built pressure more than the resting intrauterine pressure to visualize the intrauterine cavity clearly using normal saline/glycine as distending media . Therefore, a low-cost automatic pressure control bag to safely push the distension media into the uterine cavity through the inlet of hysteroscope is required.
[0005] Existing solutions can include devices to pump distension media into the uterine cavity during hysteroscopy. However, a device is needed with modified pressure cuff with auto—cut safety valves that can maintain Intrauterine pressure for pre-determined limit and is safe during day care diagnostic and therapeutic hysteroscopy.
[0006] There is a need for advancement in existing prior art by bringing a solution that is safe to use during day care diagnostic and therapeutic hysteroscopy. The solution can also help gynecologists and other related medical practitioner in medical procedures like hysteroscopy and the like. Also, the solution is cost effective.
