Embodiment 1

[0037] Please refer to figure 1 , the present embodiment provides a gastric tube 100, which includes a gastric tube body 11, the gastric tube body 11 has an inlet end 101 and an outlet end 102 for extending into the gastric cavity 41.

[0038] The gastric tube 100 passes through the nostrils, passes through the pharynx, and passes through the esophagus 20 to reach the stomach 40. The stomach 40 has a gastric cavity 41 for containing and digesting liquid food. After the gastric tube 100 is installed, the outlet end 102 is located in the gastric cavity 41 , the liquid food enters the gastric tube body 11 through the inlet port 101 , and finally enters the gastric cavity 41 through the outlet port 102 .

[0039] The junction of the esophagus 20 and the stomach 40 is the cardia 30 .

[0040] The cardia 30 is a part of the human or animal digestive tract, and is the interface between the esophagus 20 and the stomach 40 . Food in the esophagus enters the stomach through the cardia...

Embodiment 2

[0063] Please refer to Figure 4 , this embodiment also provides a gastric tube 100, the technical solution described in embodiment 1 is also applicable to this embodiment, and the technical solution disclosed in embodiment 1 will not be described again.

[0064] Figure 4 Shown in is that the unfolding part 1113 of the gastric tube 100 is in an unfolded state.

[0065] Specifically, the difference between this embodiment and Embodiment 1 is that a second pressure sensor 118 is provided on the outside of the gastric tube body 11, and the second pressure sensor 118 is located between the inlet end 101 and the stopper 111 and is used to detect the pressure of the esophagus. Pressure within 20.

[0066] When the gastric tube body 11 is placed inside the human body, the second pressure sensor 118 is located in the esophagus 20 of the human body.

[0067] Optionally, a pH sensor 119 is also provided on the outside of the gastric tube body 11. The pH sensor 119 is located between...

Embodiment 3

[0092] This embodiment also provides a nasal feeding device, which includes the aforementioned gastric tube 100 and has all the functions of the gastric tube 100 . The structure of gastric tube 100 can refer to Embodiment 1 or 2.

[0093] The nasal feeding device also includes a detection instrument, which is used to detect and control the external switch 13 and the detection part 15 . Realize the effect of automatic control.

[0094] To sum up, the present invention provides a gastric tube 100, which can receive the pressure signal in the gastric cavity 41 through the first pressure sensor 113 to control the retraction or expansion of the expansion part 1113. When the reflux situation is about to When it occurs, the expansion part 1113 is expanded to isolate the esophagus 20 and the gastric cavity 41, preventing the fluid in the gastric cavity 41 from entering the esophagus 20, and avoiding the occurrence of reflux. The overall use effect is better, the patient has a higher...

Abstract

The invention provides a stomach tube and a nasal feeding device, and belongs to the technical field of medical apparatus. The stomach tube includes a stomach tube body, the stomach tube body is provided with an entry end and an exit end for stretching into a gastral cavity, the outer side of the stomach tube body is arranged with an umbrella-shaped stopper and a first pressure sensor, the umbrella-shaped stopper includes an expansion portion and a connecting portion which is connected with the stomach tube body, the stomach tube body has a first state where the expansion portion is shrunk so that the gastral cavity can communicate with an esophagus, and the stomach tube body also has a second state where the expansion portion is expanded so that the gastral cavity can be separated from the esophagus. The stomach tube can receive pressure signals in the gastral cavity by the first pressure sensor to control the shrinkage or expansion of the expansion portion, and the reflux phenomenon is avoided. The stomach tube has a high comfort level when used, is reasonable in structural design and compact in mechanism, and has great potential in market application. The nasal feeding device includes the stomach tube and has all functions the stomach tube has.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gastric tube and a nasal feeding device. Background technique [0002] Nasogastric tube is also called nasogastric tube, nasogastric tube feeding. The gastric tube is inserted through the nostril, passes through the pharynx, and reaches the stomach through the esophagus. Care should be taken to avoid contamination of the gastric tube and prolapse of the gastric tube, resulting in aspiration. [0003] Gastric intubation is a technique that a clinician must master, and its operational purposes include: [0004] 1. Drain the gastrointestinal contents through the gastrointestinal decompression tube, and prepare for abdominal surgery. [0005] 2. For patients who cannot take food orally, inject liquid food from the stomach tube to ensure that the patient takes in sufficient nutrition, water and medicine to facilitate early recovery. [0006] The inventor found in research...
