Oropharynx protection and oxygen uptake combined device for endoscopic minimally invasive diagnosis and treatment

Abstract

The invention relates to an oropharynx protection and oxygen inhalation combined device for endoscopic minimally invasive diagnosis and treatment. The combined device comprises a seam, an oxygen inhalation nasal mask and an oropharynx protection tube; at least one mushroom-head-shaped fastener is arranged on the extension part of the seam; a connecting hole used for being connected with the fastener is formed in the flange part of the oxygen inhalation nasal mask; the fastener is detachably connected and fixed with the connecting hole; the oropharynx protection tube comprises a flexible cylindrical hollow tube and a connecting tube which are connected with each other, the upper end of the connecting tube is provided with a conical opening allowing an endoscope to enter conveniently, handles are arranged on the two sides of the connecting tube, buckles protruding outwards are arranged on the handles, and the buckles can be inserted into through holes formed in the inner walls of the two sides of a seam body by pressing the handles, so that the connecting tube is connected with the seam body; and an air bag is arranged on the lower portion of the oropharynx protection tube, an interlayer is arranged on the tube wall of the oropharynx protection tube, and an air channel is arranged in the interlayer, communicated with the air bag and communicated with an external air source.

Description

technical field [0001] The invention relates to an oropharyngeal protection and oxygen inhalation combined device for endoscopic minimally invasive diagnosis and treatment, belonging to the technical field of medical devices. Background technique [0002] In recent years, the incidence of digestive tract diseases and tumors has gradually increased, and new treatment technologies have emerged in an endless stream. Endoscopy is not only used for the examination of these diseases, but also for treatment, so the demand for endoscopic diagnosis and treatment is increasing. Endoscopic diagnosis and treatment has developed from simple polypectomy, drug injection and removal of foreign bodies to the effective radical cure of early cancers; moreover, the types of surgery cover all parts of the gallbladder, pancreas, esophagus, stomach, and large and small intestine, basically eliminating surgical blind spots. Gastric cancer, esophageal cancer, pancreatic cancer and other early tumor...

AI Technical Summary

Problems solved by technology

[0005] 2. During painless gastroscopy diagnosis and treatment, when the patient is under anesthesia or in a special position, it is difficult to insert the gastroscope into the upper esophagus, and repeated insertion may be required, which may easily cause damage to the throat mucosa or hematoma formation;

[0006] 3. When a sharp foreign body in the upper gastrointestinal tract is taken out under the gastroscope, it is easy to cause inevitable and obvious mucosal damage, or even perforation of the digestive tract;

[0007] 4. When taking out the pathological specimens resected under gastroscopy, it is easy to fall into the mouth through the oropharynx. In the absence of tracheal intubation anesthesia, it increases the difficulty of taking out and the risk of falling into the trachea and causing suffocation;

[0008] 5. For patients with acute upper gastrointestinal bleeding, because the blood clots and liquid retention in the gastric cavity cannot be quickly sucked and cleared, the best opportunity for treatment may be missed during the gastroscopy diagnosis and treatment process, which may cause aspiration and cause serious complications;

[0009] 6. When the retained food in the gastric cavity or the gastroliths taken out in pieces are taken out from the esophagus, due to their special characteristics, other surgical instruments cannot be used to collect them, and they are only attracted by the front end of the endoscope. The operation time is shortened, and it may cause suffocation caused by mis-aspiration;

[0010] 7. In the process of painless endoscopic diagnosis and treatment, if there is aspiration, coughing, etc., it is urgent to remove the mask and mouth pad at the mouth and nose, replace the pressurized mask or insert the nasopharyngeal ventilation tube, there are many obstacles, and it is impossible to quickly replace or direct intubation;

[0011] 8. The existing oxygen inhalation mask is fixed on the head by the rubber band. In the case of a long operation time, the mask may press the facial skin and the rubber band presses the eye area, resulting in deep marks and conjunctival congestion.
