Description

A kind of multifunctional nursing bed for obstetrics and gynecology

technical field

The invention relates to the technical field of medical appliances, in particular to a multifunctional nursing bed for obstetrics and gynecology.

Background technique

The gynecological examination bed is used to examine the body of female patients. During the examination, it is usually necessary to fully expose the surgical field for examination with the doctor. Usually, the lithotomy position of the bladder is used, that is, the legs are separated at 90 degrees, and the legs are placed in the lithotomy position. On the tray frame, the knee joint is bent at 90 degrees, and the legs are abducted at 90 degrees. However, the examination beds in hospitals are usually bare beds. When the patient is examining the body, the medical tools need to be picked and placed separately, which will prolong the examination time; In addition, the current clinical examination of obstetrics and gynecology will bring great trouble to pregnant women with limited mobility, so it is inconvenient to use and needs to be improved.

Announcement No. CN106109157B is an auxiliary device for gynecological diagnosis and treatment, which has made great efforts to reduce the seat plate to the lowest position and adjust the seat plate to a suitable angle at the same time, so as to facilitate the patient to sit on the seat plate and pass the diagnosis and treatment. It is necessary to adjust the backrest to an appropriate angle through the backrest angle adjustment device, and to adjust the seat plate to an appropriate height through the lifting device at the lower part of the seat plate. Moreover, it makes gynecological patients more comfortable in the process of diagnosis and treatment. When the vagina of gynecological patients is cleaned and disinfected, the waste liquid washed out is collected in a collection bucket. In the process of gynecological examination, it is mostly used in the supine position or the bladder lithotomy position. The supine position can be achieved by general hospital beds, but the bladder lithotomy position requires specific devices. The above devices cannot meet the needs and are difficult for patients with mobility. needs to be improved.
