Description

Gastroenterology diagnoses table with outpatient service

Technical Field

The invention relates to the field of medical diagnosis auxiliary equipment, in particular to an outpatient diagnosis and treatment table for the department of gastroenterology.

Background

The digestive system department is the clinical third-level subject which mainly studies diseases of esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas, etc. Patients with digestive system diseases often have obvious vomiting reaction due to the above digestive organ diseases. In the diagnosis process of the gastroenterologist, the diagnosis measures can further generate stimulation, so that the phenomenon of vomiting generated in the diagnosis process of a patient is common. Once the patient fails to vomit to the designated position, the vomit needs to be cleared away immediately by medical staff due to strong pungent smell and even disease treatment factors. The process of removing vomit not only increases the working intensity of the doctor, but also greatly occupies the effective diagnosis time of the doctor, thus leading to low diagnosis efficiency.

In order to avoid the problems, the improvement of the diagnosis and treatment table for the department of gastroenterology is provided in the prior art, so that the vomitus collecting barrel is accommodated. When a patient vomits or doctors judge that the patient probably vomits according to experience, the collecting barrel is driven to be exposed, the patient can vomit into the collecting barrel without getting up, and the phenomenon that vomitus falls off due to the fact that the patient cannot find a conventional garbage can or other appointed vomit positions due to confusion is avoided, so that diagnosis time of the doctors is utilized more effectively. For example, CN201810906120.6 discloses a special diagnosis and treatment table for medical gastroenterology, which drives a belt to rotate through a worm gear, and a collecting barrel is lifted by the belt and a small table plate for blocking an empty barrel on a table top is lifted synchronously, so that a patient can be spitted into the collecting barrel through a hole on the table top. However, in the using process, after the collecting barrel and the small table board are lifted, the small table board still needs to be detached, and other complicated steps are needed to prepare for the vomiting of the patient. Therefore, the vomiting reaction of the patient is strong, and the patient still can not wait for the vomiting to be ready, so that the technical scheme can not completely solve the problem of avoiding the random scattering of vomit.
