Description

Structure is put into with novel stomach tube that intranasal endotracheal tube combined together

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a structure is put into to novel stomach tube that combines together with intranasal endotracheal tube.

Background

The insertion of a gastric tube in a patient under general anesthesia with a tracheal cannula, or in a tracheotomy condition, is a particularly disturbing problem for anesthesiologists. On one hand, because the stomach tube is inserted when the patient is awake before the operation, the patient suffers great pain, the complication is more, the probability of the stomach tube not being in position is very high, and surgeons tend to insert the stomach tube under the general anesthesia condition in the operation more and more; on the other hand, tracheal intubation and different operative positions have a great influence on the normal anatomical position of the digestive tract, and the conventional method generally has great difficulty.

It is reported that the average failure rate of the first procedure of inserting a gastric tube for a patient with an endotracheal tube by the conventional method approaches 50-66%, and the incidence of complications of the gastric tube insertion (such as damage to the nasal and pharyngeal mucosa) increases with the number of failures. It is generally accepted that the most significant difficulty in gastric tube insertion is the anatomical factor, for reasons including: (1) The esophagus has three parts of narrowness, the neck of the esophagus is narrowed, namely the initial part of the esophagus is the first part of the esophagus, and the stomach tube is inserted into the first part of the esophagus to feel increased resistance; (2) In the state of trachea cannula, the oppression on the esophagus after the cuff of the tracheal guide tube is inflated leads to the further shrinkage of the esophageal lumen; (3) The piriform sinuses and arytenoid cartilage become the most common sites of obstruction due to the inability of the patient to coordinate with swallowing; (4) Under the condition of general anesthesia muscle relaxation, the tongue root drops, and the oral trachea guide tube and the bite block interfere, so that the stomach tube is easy to be wound and knotted; (5) In open chest surgery, gastric tubes are more difficult to place due to the lateral position.

In addition, the difficulty of gastric tube placement also relates to the properties of the gastric tube material. The gastric tube is usually made of polyurethane or silicone, and the softer texture can reduce trauma, but if a larger anatomical barrier is encountered, the gastric tube is easy to coil or knot, and after multiple intubation failures, the gastric tube can be heated by body temperature and becomes softer. In addition, four asymmetric side holes are formed at the far end of the stomach tube to form a weak point, so that the tail end of the stomach tube is easy to bend and break.

In the prior art, a variety of methods have been proposed for the intraoperative placement of gastric tubes. (1) Self-made metal guide wires or duodenal nutrition tube guide steel wires are used. The advent of the guide-wire feeding tube ameliorated this problem to some extent, but in most cases repeated attempts were still required to succeed. The self-made steel wire is relatively complex and has potential damage to the machine body. The feeding tube guiding steel wire is not matched with the common stomach tube usually and is easy to loosen or slide out. (2) The stomach tube is inserted under the visual condition of a common laryngoscope or a visual laryngoscope. However, it is often not easy to see the anatomy due to obstruction of the intraoral tracheal guide tube and bite block. In addition, the trachea cannula balloon is usually loosened and bent forceps are used in the oral cavity, which may affect the position of the trachea cannula and risk the aspiration of gastric juice reflux. It cannot be used in lateral position. And (3) placing under a gastroscope for assistance. The success rate is reported to reach 100%, and the method has few complications and is a safe and effective method. However, assisted placement under a gastroscope generally requires large equipment, is complicated to operate, and is expensive. (4) The tracheal guide tube guiding method is a better method, but the prior researches adopt a common tracheal guide tube as a guide tube, and the common tracheal guide tube has the following defects: because the tail end of the stomach tube needs to be connected with a gastrointestinal pressurizing bag, the diameter is thick generally, the stomach tube cannot directly pass through a common trachea guide tube, after the stomach tube is in place, the whole trachea guide tube needs to be cut off by scissors and stripped from the stomach tube, the operation is relatively troublesome, time and labor are wasted, and the stomach tube can be damaged or shifted.

However, for some special patients, if the patient needs to be placed with the gastric tube but cannot cooperate with the gastric tube, if the patient is not under anesthesia, some patients may struggle or cannot swallow the gastric tube when the gastric tube is placed, thereby affecting the introduction efficiency of the gastric tube.

SUMMERY OF THE UTILITY MODEL
