Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an integrated gastrointestinal tube using a floating balloon for pressure measurement. Background Art

[0002] ICU patients often suffer from gastrointestinal dysfunction, and numerous studies have demonstrated the significant benefits of enteral nutrition (EN) for maintaining gastrointestinal function and microbiota. Nasogastric tubes are the preferred route of EN in clinical practice. A nasogastric tube is a tube inserted through the nostrils, passing through the pharynx and esophagus to the stomach. However, due to the anatomical characteristics of the digestive tract and gastrointestinal dysfunction in critically ill patients, EN via nasogastric tubes is prone to complications such as VAP, gastric retention, gastrointestinal bleeding, reflux aspiration, and diarrhea, often resulting in treatment outcomes worse than expected, thereby prolonging treatment time and increasing treatment costs. Because the nasogastric tube passes through the pylorus, nutrients are directly absorbed by the intestine, providing more ideal nutritional support and significantly reducing the incidence of reflux aspiration and lung infection.

[0003] Previous studies have shown that dynamic management approaches, such as adjusting feeding methods and rates based on intra-abdominal pressure (IAP) and gastric residual volume (GRV) monitoring data, can further improve patients' nutritional status. However, IAP is affected by objective factors and lacks accuracy, while GRV monitoring requires ultrasound expertise, and data acquisition is not fast or direct. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a gastrointestinal integrated tube using a floating balloon pressure measurement to achieve rapid and direct acquisition of gastrointestinal pressure values, dynamic and continuous monitoring of gastrointestinal pressure, and to guide the implementation of clinical enteral nutrition.

[0005] According to an embodiment of the present application, a gastrointestinal integrated tube using a floating balloon pressure measurement is provided, including a gastrointestinal nutrition tube with an integrated double-lumen structure, wherein the gastric tube 55 cm and the head end of the intestinal tube of the gastrointestinal nutrition tube are respectively connected to an intragastric floating pressure measuring balloon and an intestinal floating pressure measuring balloon, a first catheter and a second catheter are respectively placed in the gastric tube cavity and the intestinal tube cavity of the gastrointestinal nutrition tube, one end of the first catheter is connected to the intragastric floating pressure measuring balloon, and the other end is divided into two catheters, the ends of the two catheters serve as a first gas injection port and a first pressure measuring port, respectively, a first inflation ball is installed on the first gas injection port, and a first pressure sensor is installed on the first pressure measuring port, one end of the second catheter is connected to the intestinal floating pressure measuring balloon, and the other end is divided into two catheters, the ends of the two catheters serve as a second gas injection port and a second pressure measuring port, respectively, a second inflation ball is installed on the second gas injection port, and a second pressure sensor is installed on the second pressure measuring port.

[0006] Optionally, the gastric tube of the integrated gastrointestinal nutrition tube is 100 cm long and 5.3 mm in outer diameter, and the intestinal tube is 40 cm long and 4 mm in inner diameter.

[0007] The technical solutions provided by the embodiments of the present application may have the following beneficial effects:

[0008] As can be seen from the above embodiments, the present application is a gastrointestinal integrated tube that only needs to be placed in one side of the patient's nasal cavity to reduce patient discomfort. At the same time, a gastric floating pressure measuring balloon and an intestinal floating pressure measuring balloon are connected to the 55cm position of the gastric tube and the head end of the intestinal tube of the gastrointestinal nutrition tube, respectively. The pressure in the stomach and intestines are collected through sensors, respectively, to more directly reflect the pressure in the gastrointestinal tract. The balloon design has a larger contact surface, and pressure can be felt on all sides, which can obtain more accurate pressure, guide the clinician to better adjust the feeding method and feeding speed, and adopt a dynamic management method.

[0020] The method of using the utility model is as follows:

[0021] Indwelling: The gastrointestinal integrated tube 1 is indwelled in the same manner as the indwelling intestinal tube. Only one catheter needs to be indwelled to solve the function of two catheters.

[0022] Intragastric pressure measurement: The first inflation ball 6 can be used to inflate gas through the first gas injection port 7 to fill the intragastric floating pressure measuring balloon 2 with gas. The intragastric floating pressure measuring balloon 2 is connected to the first pressure sensor on the first pressure measuring port 8 through the first catheter 4 for pressure measurement. The pressure in the intragastric floating pressure measuring balloon 2 can be detected by the first pressure sensor to reflect the pressure in the stomach.

[0023] Intestinal pressure measurement: The intestinal floating pressure measuring balloon 3 is inflated with gas by injecting gas through the second gas injection port 9 using the second inflation ball 15. The intestinal floating pressure measuring balloon 3 is connected to the second pressure sensor on the first pressure measuring port 10 via the second catheter 5 for pressure measurement. The second pressure sensor detects the pressure within the intestinal floating pressure measuring balloon 3, thereby reflecting the pressure within the intestine.
