The dosing device comprises an automatic dosing device, a fiberoptic bronchoscope and an oral cavity supporting device, wherein the automatic dosing device comprises a medicine inlet, a medicine outlet and an automatic dosing mechanism, the medicine inlet is connected with a flexible medicine bag, the medicine outlet is connected with a dosing tube, the interiors of the medicine inlet and the medicine outlet communicate with each other through the automatic dosing mechanism, the fiberoptic bronchoscope comprises a display screen, an optical fiber cable and a lens which are connected in sequence, the dosing tube and the optical fiber cable are connected with an insertion tube through a fixed tongue piece, the insertion tube communicates with the dosing tube, a dosing spray head is arranged at the front end of the insertion tube, the optical fiber cable is arranged in the insertion tube and penetrates out of the front end of the insertion tube in a sealed mode, and the lens is arranged at the front end of the dosing spray head. According to the above scheme, automatic intermittent dosing can be achieved through the automatic dosing device, accurate dosing in the trachea of a patient is achieved through the fiberoptic bronchoscope, the dosing spray head can be automatically closed, a liquid medicine can be prevented from spilling and leaking, and in addition, the comfort of the patient can be improved through an oral cavity supporting device.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug delivery device for conscious tracheal intubation. Background technique [0002] Endotracheal intubation refers to the technology of placing a special endotracheal tube into the trachea through the glottis. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory suction and prevention of aspiration. Endotracheal intubation technology has been It has become an important measure in the rescue process of cardiopulmonary resuscitation and critically ill patients with respiratory dysfunction. important role. Endotracheal intubation can timely suck out secretions or foreign bodies in the trachea, prevent foreign bodies from entering the respiratory tract, keep the respiratory tract unobstructed, perform effective artificial or mechanical ventilation, and prevent patients from hypoxia and carbon dioxide retention. ...

AI Technical Summary

Problems solved by technology

[0004] Generally, cricothyroidotomy is required for awake tracheal intubation. Cricothyroidotomy is one of the clinical first aid methods for patients with airway obstruction and severe dyspnea. It can buy time for tracheotomy and is the first aid on the spot. An important part of the puncture, but this kind of puncture has trauma, which will increase the patient's sense of fear. Therefore, before performing an awake tracheal intubation on the patient, it is necessary to inject anesthetics into the patient's trachea. In the prior art, due to the injection tube The front end of the esophagus is operated in the patient's body and cannot be directly observed. The current operation is based on the experience of the doctor, and it is easy to insert into the esophagus. At the same time, the mouth of the injection tube is easy to leak the medicine, which is not conducive to the precise administration of the trachea
