Description

Upper gastrointestinal endoscopy type laryngeal mask

technical field

The utility model belongs to the technical field of medical instruments, in particular to an upper digestive tract endoscopy type laryngeal mask.

Background technique

In the traditional painless upper gastrointestinal endoscopy, the patient is first anesthetized, and the patient is put into the gastrointestinal endoscope after falling asleep. At present, all general anesthesia causes different degrees of respiratory depression to patients. Therefore, under this anesthesia state, it is easy to cause hypoventilation, oxygen saturation drop, and anesthesia accidents. However, once an anesthesia accident occurs clinically, the upper gastrointestinal endoscope needs to be pulled out before the patient can be fully rescued. It is a potentially huge risk for patients with poor cardiopulmonary function. In order to ensure that the patient has sufficient lung ventilation, the tracheal intubation is performed after the patient is given general anesthesia, but the upper gastrointestinal endoscopy and the tracheal intubation are in the same channel. In this case, the endotracheal tube is inserted next to the The endoscopic catheter may cause upper gastrointestinal damage due to the volume problem, so the endotracheal intubation examination will cause unnecessary damage to the patient and even increase the economic burden. In summary, traditional painless upper gastrointestinal endoscopy has the following disadvantages: 1. It is easy to irritate the upper respiratory tract and cause laryngospasm; 2. It is easy to cause hypoventilation and cause hypoxia in patients. 3. It may cause aspiration. 4. Rescue takes time.

The current upper gastrointestinal endoscopy in the prior art is to anesthetize the patient, keep the patient breathing spontaneously, and use ultra-short-acting intravenous anesthetics for anesthesia to ensure that the patient can wake up in time after the examination. In order to reduce the suffering of patients with endotracheal intubation, clinically some patients adopt a laryngeal mask for ventilation, which can eliminate the trauma of the endotracheal intubation to the patient. The gastric tube interface is thin, but the gastric tube interface is too thin to be inserted into the endoscope. At present, upper gastrointestinal endoscopy is an important examination method for the diagnosis of gastrointestinal diseases, and it is the best method and means to obtain diseased tissue. The number of upper gastrointestinal endoscopy in various hospitals is increasing year by year. How can we provide a comprehensive A kind of upper digestive tract endoscopic examination type laryngeal mask that can not only ensure sufficient pulmonary ventilation, but also gastroscopy and assisted breathing can be carried out simultaneously has become an urgent demand of people.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides an upper digestive tract endoscopic examination type laryngeal mask which can not only ensure sufficient lung ventilation, but also perform gastroscopic examination and assisted breathing simultaneously.

The utility model is realized through the following technical solutions: an upper gastrointestinal endoscopic examination type laryngeal mask, comprising an inflatable bag, an endoscopic inspection pipeline and a breathing pipeline, the endoscopic examination pipeline and the breathing pipeline are respectively connected with the inflatable bag, An inflatable tube is connected to the inflatable bag, and a one-way valve is connected to the inflatable tube. The endoscopic inspection pipeline and the respiratory pipeline are set independently of each other. At the bottom of the inflatable bag, the endoscopic examination inner port is located at the lower end of the inflatable bag, the outer diameter of the endoscopic examination outer port is 1.5 cm, and the inner diameter is 1.2 cm; the inner diameter of the endoscopic examination inner port 7 is 1.2 cm.

The outer diameter of the breathing tube is 1.5 cm, and the inner diameter is 0.65 cm.

The upper gastrointestinal endoscopy laryngeal mask of the utility model is a disposable plastic laryngeal mask, which conforms to the physiological anatomical curve of the human throat and throat,

The beneficial effects of the utility model are: the utility model expands the straight diameter of the endoscopic inspection pipeline on the basis of the traditional laryngeal mask, which can not only ensure the smooth progress of the upper gastrointestinal endoscopy, but also ensure that the patient has enough Ventilation, and once an anesthesia accident occurs, it can be quickly put into rescue without removing the endoscope. The independent upper gastrointestinal endoscopy tube is separated from the respiratory tube, which can significantly reduce the occurrence of reflux and aspiration, and facilitate the placement and positioning of the laryngeal mask, and the insertion is simple. The inflatable bag can also strengthen the sealing of the hypopharynx, and the laryngeal mask has good sealing performance, which can also ensure effective ventilation during long-term endoscopy. If the utility model is popularized, the risk of patients in the examination process can be greatly reduced, the safety factor can be improved, and the incidence rate of aspiration can be greatly reduced. The airway of the laryngeal mask of the utility model is isolated from the digestive tract to ensure sufficient lung ventilation, and the outer end of the laryngeal mask is connected to a ventilator or a breathing bag for assisted breathing, so that gastroscopic examination and assisted breathing can be performed simultaneously.
