Description

Visual stomach tube
Technical Field
The invention belongs to the technical field of medical catheters, and particularly relates to a stomach tube with a visual function.
Background
Gastric tubes are used to help patients who cannot swallow the stomach to deliver the necessary moisture, food, and medication in special cases. And may act to attract gastric contents. Gastric tubes are generally composed of a catheter, a connector, a guide wire, and the like. Currently, a nasogastric tube is commonly used in the market, and is inserted through a nostril, passes through a pharynx and enters a stomach through an esophagus. When in intubation, the patient needs to be placed in the body position, the nasal cavity is cleaned and lubricated, the head of the patient is tilted backwards, the stomach tube and the nostril form an angle of 60 degrees and are inserted, and the patient continues to be inserted into the nasopharynx; when the stomach tube is inserted to 15CM (meeting throat), 1-2ml of lubricant is instilled along the outer wall of the stomach tube, then the head of the patient is supported, and the lower jaw of the patient is tightly attached to the chest wall, so that the radian of the throat is increased, the stomach tube conveniently slides along the rear wall and smoothly enters the esophagus through the throat. At this moment, the stomach tube is slowly inserted to the required length and then fixed while the patient is ordered to swallow. It can be said that the gastric tube needs to go through a long and complicated procedure when being inserted into the human body. The current market adopts a blind insertion method, medical workers need to have abundant intubation experience, and the condition that a gastric tube enters the internal tissues of the body of a human stomach cannot be seen in the insertion process. Generally, doctors need to observe the pathological changes of stomach tissues and need to take devices such as gastroscopes and the like. The lower gastroscope is an extra work for medical staff and a pain for patients. In addition, the stomach lesion is treated by adopting a minimally invasive interventional catheter in clinic. And at present, the stomach tube is fixed clinically, and has certain problems, and the stomach tube falls off because of insecure fixation, so that the development of a stomach tube capable of observing the pathological changes of stomach tissues is necessary. And the visual stomach tube with the balloon is matched with the laryngeal mask for use, so that the risk of backflow and aspiration can be prevented.

The stomach tube with the visual function is developed to realize the visual operation of stomach tube implantation and the observation of the pathological change condition of the stomach tissue of a human body clinically.
Specifically, the catheter is provided at its rear end with a connector 12 through which water, food and medication are delivered to the catheter. Can also suck gastric contents
Before a medical worker inserts the stomach tube into a human body, the transmission tube and the camera can be inserted into the stomach tube firstly, the transmission tube can support the soft stomach tube to smoothly enter the stomach of the human body, and the phenomena of bending and kinking are avoided; the visual operation of stomach tube implantation can be realized through the visual system.
Example 2
Because the stomach tube is easy to fall off, the key is that how to fix the stomach tube to keep the stomach tube stably kept in the body of a patient, the common operation means of the existing medical treatment is to apply white rubber adhesive tapes to paste the rear side of the stomach tube on the nose part, then the adhesive tapes are easy to fall off because the mouth and the nose of the patient can move frequently, and the stomach tube is not firm to be fixed through the adhesive tapes;
with reference to fig. 4-6, in the visible gastric tube provided in example 1 according to this embodiment, a positioning balloon and an inflation member communicating with the positioning balloon are provided on the catheter, the balloon is disposed at the rear side of the side hole and is adapted to be capable of sealing the cardia in an inflated state after entering the stomach with the head end 11 of the catheter, so that the gastric tube can be stably held in the stomach.
Furthermore, the stomach tube is cooperated with the laryngeal mask for practical use, and the air bag is plugged at the esophagus to fundamentally prevent liquid from flowing back from the stomach to the air passage, so that the technical problem which cannot be solved by the backflow of the laryngeal mask at present is solved.
Specifically, the inflation piece comprises an inflation cavity 70 formed on the inner wall of the catheter, an inflation tube 71 communicated with the inflation cavity and arranged outside the catheter, an indicating air bag 72, a quick release connector 73 and an inflation valve 74.
Thus, after the visible stomach tube enters the body, such as the stomach, the air sac can be inflated through the inflation cavity to expand the visible stomach tube to play a positioning role; the inflatable air bag is adopted to prevent the catheter from being inserted into the body, the transverse penetration size of the catheter is not changed when the inflatable air bag is in an uninflated state, and after the catheter passes through the esophagus to reach the stomach through the pharynx, the expansion degree of the positioning air bag is controlled by controlling the inflation process so that cardias with different sizes can be effectively blocked.
