Embodiment 1

[0034] A gastric juice pipeline system with acid reflux reminder function, such as Figures 1 to 4 As shown, it includes a laryngeal mask body 1 that can be inserted into the patient's larynx and a gastric tube 2 that can pass through the laryngeal mask body 1 and extend to the patient's stomach; The stomach tube channel 12 through which the tube 2 passes; the head of the stomach tube 2 is provided with at least one gastric juice drainage port 21; When gastric acid flows through the indicating part 22 along the gastric tube 2, the gastric acid can contact the color-developing material 221 embedded in the indicating part 22; the color of the color-developing material 221 can change when encountering acid.

[0035] In this embodiment, the indicating part 22 is tubular and integrally formed in the gastric tube 2; the color-developing material 221 is tubular and embedded in the indicating part 22; the inner wall of the indicating part 22 is provided with a group of radial capillar...

Embodiment 2

[0040] A gastric juice pipeline system with acid reflux reminder function, such as figure 1 , 2 , 5 and 6, it includes a laryngeal mask body 1 that can be inserted into the patient's larynx and a gastric tube 2 that can pass through the laryngeal mask body 1 and extend to the patient's stomach; the laryngeal mask body 1 is provided with an airway for gas to pass through 11 and a gastric tube channel 12 for the gastric tube 2 to pass through; the head of the gastric tube 2 is provided with at least one gastric juice drainage port 21; When gastric acid flows through the indicating part 22 along the gastric tube 2, the gastric acid can contact the color-developing material 221 embedded in the indicating part 22; the color of the color-developing material 221 can change when encountering acid.

[0041] In this embodiment, the indicating part 22 is in the shape of a tube, and is connected in series with the stomach tube 2 with an interference fit; the chromogenic material 221 is i...

Embodiment 3

[0046] A gastric juice pipeline system with acid reflux reminder function, such as figure 1 , 2 , 5 and 6, it includes a laryngeal mask body 1 that can be inserted into the patient's larynx and a gastric tube 2 that can pass through the laryngeal mask body 1 and extend to the patient's stomach; the laryngeal mask body 1 is provided with an airway for gas to pass through 11 and a gastric tube channel 12 for the gastric tube 2 to pass through; the head of the gastric tube 2 is provided with at least one gastric juice drainage port 21; When gastric acid flows through the indicating part 22 along the gastric tube 2, the gastric acid can contact the color-developing material 221 embedded in the indicating part 22; the color of the color-developing material 221 can change when encountering acid.

[0047] In this embodiment, the indicating part 22 is in the shape of a tube, and is connected in series with the stomach tube 2 with an interference fit; the chromogenic material 221 is i...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a gastric juice pipeline system with an acid regurgitation prompting function. The system comprises a laryngeal mask body capable of being inserted into the throat of a patient and a stomach tube capable of penetrating through the laryngeal mask body and extending to the stomach of the patient. An air passage through which air passes and a stomach tube passage through which a stomach tube passes are arranged in the laryngeal mask body; at least one gastric juice drainage opening is formed in the stomach tube head; and at least one indicating component capable of indicating regurgitation of gastric acid is arranged in the stomach tube. When the gastric acid flows through the indicating component along the stomach tube, the gastric acid can be in contact with the color developing material embedded in the indicating component; the color of the color developing material changes when meeting acid, so that a doctor is reminded to treat in time. According to the gastric juice pipeline system with the acid regurgitation prompting function, an obvious prompt can be given out when gastric acid regurgitation occurs, and the response time is short and ranges from 0.1 s to 0.3 s. Meanwhile, a guide spring with a proper length is embedded in the tube wall of the stomach tube, so that the stomach tube can penetrate through the stomach tube channel more conveniently.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a gastric juice pipeline system with an acid reflux prompt function. Background technique [0002] The laryngeal mask is a medical device that was successfully developed in the mid-1980s and used clinically. Since it was introduced into China in the 1990s, the use of the laryngeal mask has made significant progress, and its application range has become wider and wider. At present, one of the important uses of the laryngeal mask is to establish a safe airway in general anesthesia surgery. The advantage of using a laryngeal mask instead of an endotracheal tube is that it can reduce the irritation to the patient and significantly reduce postoperative pharyngeal discomfort. However, during the use of the laryngeal mask, the patient's gastric juice may reflux, and once gastric reflux occurs, it is easy to cause aspiration. Therefore, doctors must always pay atten...
