Description

Painless gastroscope neck posture auxiliary fixing frame integrating mask

Technical Field

The invention relates to the technical field of gastroscope auxiliary frames, in particular to a neck posture auxiliary fixing frame for painless gastroscopes, which is integrated with a mask.

Background

Gastroscopy is an endoscopic device used to examine and treat diseases of the digestive tract, including the esophagus, stomach and intestine. The utility model can observe the internal conditions of the digestive tract in real time by inserting an elongated tubular instrument and providing a camera and a light source, thereby helping doctors to diagnose various diseases such as gastritis, gastric ulcer, intestinal tumor, etc. In addition, the gastroscope may perform several therapeutic procedures, such as biopsy, hemostasis, polypectomy, etc.

In performing gastroscopy, the position of the patient is critical, especially the angle of the head and torso, and the smooth insertion of the gastroscope requires a specific position. Proper head and trunk angles can reduce the resistance of the airway and the alimentary canal, so that the gastroscope can pass more smoothly, the body position of a patient can be adjusted to optimize the visual field of a doctor, and the endoscope can be ensured to clearly observe each part of the alimentary canal in the examination process. Incorrect posture may cause a view to be blocked, thereby affecting the diagnosis result, and maintaining the incorrect posture for a long time may cause the patient to feel discomfort or pain. Through adjusting the whole position, the discomfort of the patient in the inspection process can be relieved, the comfort and tolerance of the patient are improved, and under certain conditions, the damage risk caused by accidental movement can be reduced by fixing the head and trunk angles of the patient. Ensuring the stability of the patient throughout the examination helps to prevent inadvertent displacement of the endoscope.

The posture fixing frame in the traditional method often depends on manual operation of medical staff, so that discomfort and anxiety of patients in the examination process are caused, meanwhile, the working intensity of medical staff is increased, and equipment such as a throat or an oxygen mask is also arranged after the fixing frame is arranged, so that the steps are complicated.

The prior art patent with the publication number of CN116350460A discloses a gastroscope head fixing frame, which comprises an inspection bed, wherein sliding blocks are connected to the surfaces of two sides of the head of the inspection bed in a sliding way, supporting plates are fixedly connected to the top surfaces of the sliding blocks, sliding rods are fixedly connected between the two supporting plates, connecting frames are connected to the surfaces of the sliding rods in a sliding way, elastic pads are arranged on the top surfaces of the connecting frames, a tightening module is arranged on one side surface of the connecting frames, a fixing belt is arranged between the other side of the connecting frames and the tightening module, the fixing belt is used for fixing, after the fixing is finished, a patient can still adjust the head position of the patient by sliding the connecting frames on the surfaces of the sliding rods, so that the operation after a doctor is facilitated, the shaking degree of the patient due to uncomfortable feeling of the doctor is reduced when the doctor is plugged into the mouth cavity of the patient, the operation of the doctor is more convenient, and the working efficiency of the doctor is improved.

However, in the above technical scheme, the fixing frame cannot be automatically adjusted according to the head size of the patient, and the respiratory mask or the throat still needs to be installed subsequently, so that the flow is more, the working efficiency is low, the adjustment of the angle postures of the head and the chest of the patient is not accurate enough, the fixed angle cannot be quantified, the record is not restored, the angle self-locking and the quick disassembly cannot be realized after the angle adjustment is finished, and the steps are still complicated and not practical enough.
