Description

Tracheal catheter with mouth pad for gastroscope treatment

Technical Field

The invention belongs to the technical field of medical instruments, and relates to a tracheal catheter with a mouth pad, which is suitable for gastroscope treatment.

Background

At present, a gastroscope is not only an examination tool but also a good treatment tool, can complete the excision of pathological changes of a stomach wall, an esophagus mucosa layer or an intrinsic muscle layer, and provides high-quality and minimally invasive treatment for patients. However, these treatments are usually completed under general anesthesia of the tracheal intubation, which is bound to the situation that the oral cavity of a patient needs to occupy two pipelines of a gastroscope and a tracheal catheter at the same time, and brings great inconvenience to doctors during treatment operation.

At present, the tracheal catheter used in the market only has a single pipeline, and when the operation is performed, an additional mouth pad is almost needed to be arranged to separate the two pipelines, and then the tracheal catheter and the tooth pad are wound together by medical adhesive plaster and are adhered to the skin of the head and the face of a patient. At this time, if the tracheal catheter is not fixed properly or soaked in adhesive tape, saliva or blood, etc., the adhesiveness is easily lost, and the tracheal catheter slips. And the operation of fixing the tracheal cannula by an anaesthetist needs to be carried out in multiple steps, so that the operation cannot be completed in one step, and the working efficiency is reduced.

Furthermore, hospital staff is now very limited in number and there is significant uncertainty in the number of patients. If the number of patients suddenly increases in a certain time period, the medical staff can not be busy.

In order to improve the working efficiency and the safety factor of a hospital, reduce the pain of a patient as much as possible and improve the satisfaction degree of the patient, some less important steps are automated in the treatment process, so that the hands of people can be well saved, and the workload of medical care is reduced. Thus, more patients are treated in the same time period, with the same number of patients.
