Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a mobile nursing device. Background Art

[0002] Anesthesia means using drugs or other methods to temporarily make the patient lose all or part of the sensation so as to achieve painless surgical treatment. Anesthesiology is a science that uses the basic theories, clinical knowledge and techniques of anesthesia to eliminate surgical pain, ensure patient safety and create good conditions for surgery. Now, anesthesiology has become a specialized independent discipline in clinical medicine. As a new type of profession, anesthesia nursing is increasingly valued and cultivated by major hospitals. Anesthesia nursing can be well used in various surgeries, bringing convenience to the smooth implementation of surgery.

[0003] At present, when performing preoperative anesthesia on patients, it is necessary to put surgical tools such as scalpels, tweezers, and forceps needed for the operation on a tray so that the doctor can quickly take them and ensure the efficiency of the operation. However, the existing operating room anesthesia care devices still have the following shortcomings: First, the existing operating room anesthesia care devices cannot adjust the rotation angle of the tray according to the required use, resulting in the direction of the tray not being consistent with the doctor's standing position, so that the doctor cannot conveniently take the tools, which may have an adverse effect on the operation; second, most of the existing operating room anesthesia care devices will choose to install universal wheels to ensure flexible movement, and the operating room anesthesia care devices installed with universal wheels are often too flexible and may slide, which is not conducive to medical staff taking surgical tools.
