[0027] Embodiment one

[0028] Refer to Figs. 1-3 , A multifunctional gastrointestinal nutrient tube with sensors comprises a tube body 1 and four connecting tubes 13.

[0029] Refer to Figs. 1-2 , The inside of the tube body 1 is provided with a nutrition delivery cavity 2, a gastrointestinal decompression cavity 3, a medicine delivery cavity 4 and a function cavity 5 extending from the top end to the tail end and not communicating with each other. Specifically, the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3 and the medicine delivery cavity 4 penetrate the top end and the tail end of the tube body 1. It can be understood that the linear length of the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3, the medicine delivery cavity 4 and the tube body 1 is consistent, and a through hole matched with the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3 and the medicine delivery cavity 4 is formed on the surface of the top end and the tail end of the tube body 1, which is the opening of the corresponding end of the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3 and the medicine delivery cavity 4. The function cavity 5 only penetrates the tail end of the tube body 1, and a circular hole matched with the function cavity 5 is formed on the surface of the tail end.

[0030] Among them, the surface of the top end and the tail end refers to the upper and lower bottom surfaces of the tube body 1; and in this embodiment, the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3, the medicine delivery cavity 4 and the function cavity 5 are designed as circular cavities; at the same time, among the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3, the medicine delivery cavity 4 and the function cavity 5, the cross-sectional area of the nutrition delivery cavity 2 is the largest, because the nutrition delivery cavity 2 is used for delivering nutrient solution or extracting samples in the gastrointestinal tract for detection, therefore a larger cross-sectional area can improve the rate of delivering nutrient solution, and at the same time a large amount of liquid samples in the gastrointestinal tract can be quickly obtained; and the cross-sectional area of the function cavity 5 is the smallest, because the function cavity 5 is used for realizing wired connection of the sensor on the gastrointestinal nutrient tube, therefore a larger space is not needed.

[0031] The gastrointestinal decompression cavity 3 is used for decompressing the gastrointestinal tract, and the medicine delivery cavity 4 is used for delivering medicine to the gastrointestinal tract; therefore, the gastrointestinal decompression cavity 3 and the medicine delivery cavity 4 can be adaptively adjusted.

[0032] Refer to Fig. 1 , One end of the four connecting tubes 13 is connected with the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3, the medicine delivery cavity 4 and the function cavity 5 on the surface of the tail end of the tube body 1 respectively, and the other end is used for connecting a nutrient solution delivery pipe, a medicine delivery pipe and the like. At the same time, the gastrointestinal nutrient tube outputs nutrient solution or medicine through the top end of the tube body 1.

[0033] Through the above setting, the nutrition delivery cavity 2, the gastrointestinal decompression cavity 3, the drug delivery cavity 4 and the function cavity 5 are all arranged inside the tube body 1, avoiding the external connection of the corresponding pipelines on the side surface of the tube body 1, thereby reducing the transverse section of the gastrointestinal nutrition tube as a whole, so that the gastrointestinal nutrition tube can enter the digestive tract through the oral cavity of the human body during use and realize the process of corresponding infusion, drug delivery or gastrointestinal decompression, thereby ensuring that the functions of the human body are maintained in a stable state.

[0034] Referring to Fig. 1 The tube body 1 is provided with a notch 18 and is divided into a first section 11 and a second section 12; meanwhile, the multifunctional gastrointestinal nutrition tube further comprises a first sensor group, a second sensor group and a third sensor group, and the first sensor group and the second sensor group are arranged on the outer surface of the tube body 1 in the first section 11, and the third sensor group is arranged on the outer surface of the tube body 1 in the second section 12.

[0035] Specifically, the first sensor group comprises a position sensor 6, a pH sensor 7 and a biochemical sensor 8; wherein the position sensor 6, the pH sensor 7 and the biochemical sensor 8 are all arranged on the outer surface of the tube body 1 near the top end of the first section 11 in a nested manner; meanwhile, the position sensor 6 is closest to the top end of the nutrition tube, so as to determine which position in the gastrointestinal tract the top end of the gastrointestinal nutrition tube is located.

[0036] Through the above setting, during use of the gastrointestinal nutrition tube, the first section 11 needs to reach the pylorus (in the duodenum and / or in the jejunum) of the human body and ensure that the drug, nutrient liquid and other substances are delivered to the small intestine, so as to provide nutrition or drug for the human body through enteral nutrition, thereby avoiding the discomfort caused by intravenous nutrition to the human body; moreover, enteral nutrition is more in line with the natural absorption of the human body and will not have too much impact on the digestion of the human body. Meanwhile, the position sensor 6, the pH sensor 7 and the biochemical sensor 8 also measure the parameters after the pylorus (in the duodenum and / or in the jejunum), so as to determine whether the gastrointestinal nutrition tube reaches the appropriate position.

[0037] In this embodiment, the second sensor group only comprises a pressure sensor 9, and the pressure sensor 9 is also arranged on the outer surface of the tube body 1 near the notch 18 in the first section 11 in a nested manner.

[0038] During use of the gastrointestinal nutrition tube, the pressure sensor 9 is used to monitor the pressure data of the pylorus between the stomach and the intestine, so as to determine whether the stomach and the intestine of the human body need to be decompressed.

[0039] Finally, the third sensor group comprises a pH sensor 7 and a temperature sensor 10; and the pH sensor 7 and the temperature sensor 10 are both arranged on the outer surface of the tube body 1 near the notch 18 in the second section 12 in a nested manner.

[0040] Wherein, the gastrointestinal nutrition tube is in use, the second section 12 is located in front of the pylorus (in the stomach), and the pH sensor 7 and the temperature sensor 10 are used for monitoring the parameters in the stomach, so that the state of the stomach can be obtained.

[0041] And the sensors in the above-mentioned first sensor group, second sensor group and third sensor group transmit data in a wired manner after monitoring the corresponding data parameters.

[0042] Specifically, in the embodiment, the nesting mode is that a ring-shaped groove is formed on the surface of the tube body 1, and the sensors are nested in the groove to fix the sensors; meanwhile, fine holes are formed at positions corresponding to the sensors in the functional cavity 5, and a transmission line is arranged in the functional cavity 5, the transmission line is connected with the sensors through the fine holes, so that the data obtained by the sensors are transmitted in a wired manner.

[0043] In addition, in the embodiment, the cross-sectional area of the tube body 1 in the first section 11 is smaller than the cross-sectional area of the tube body 1 in the second section 12; this is to facilitate the first section 11 to enter the pylorus (in the duodenum and / or in the jejunum) and measure the parameters in the duodenum and / or in the jejunum; at the same time, it is beneficial for the second section 12 to be located in front of the pylorus (in the stomach) and measure the parameters in the stomach.

[0044] Meanwhile, in the embodiment, the material of the gastrointestinal nutrition tube (including the tube body 1 and the connecting pipe 13) is selected from medical-grade biocompatible materials, such as silicone, polyurethane and the like, to ensure the flexibility and safety of the pipeline and reduce the irritation to the mucosa of the digestive tract.

[0045] Referring to Fig. 3 Taking the delivery of the nutrient solution as an example, the use steps of the gastrointestinal nutrition tube are described as follows:

[0046] Step one: first, connect the liquid 15 (nutrient solution) and the connecting pipe 13 corresponding to the tail nutrition delivery cavity of the gastrointestinal nutrition tube through the infusion tube, and turn on each sensor; at the same time, connect the transmission line in the functional cavity 5 with the data processing unit 16; wherein, the data processing unit 16 is connected with the display 17 and is used for displaying various parameters.

[0047] Step two: deliver the gastrointestinal nutrition tube through the oral cavity into the esophagus, and observe the parameters on the display 17 to ensure that the gastrointestinal nutrition tube is correctly inserted into the esophagus.

[0048] Step three: transport the gastrointestinal nutrition tube to the appropriate position and observe the parameters on the display 17 to ensure that the first section 11 of the gastrointestinal nutrition tube is located at the appropriate position in front of the pylorus (in the duodenum and / or in the jejunum), and the second section 12 is located at the appropriate position in front of the pylorus (in the stomach).

[0049] Step four: Start the infusion, and observe the data monitored by each sensor on the display 17 in real time to avoid abnormal conditions of the patient's gastrointestinal tract.

[0050] Step five: After the infusion is completed, slowly withdraw the gastrointestinal feeding tube, and turn off each sensor, the data processing unit 16, and the display 17.

[0051] In this embodiment, the data processing unit 16 includes a microprocessor, which is used to process each parameter monitored by each sensor.

[0052] At the same time, the gastrointestinal feeding tube provided in this embodiment is not only used for monitoring various indicators during infusion or eating of the patient, but also can be used for real-time monitoring of the gastrointestinal function, gastric cavity, and abdominal cavity pressure of the patient in the state of water fasting and food fasting of the patient, thereby providing safety guarantee for timely discovery of disease course changes and the like. In addition, the gastrointestinal feeding tube can also be used for various clinical service scenes, such as extraction of gastric juice, direct intervention of drugs, surgical operation, and the like.

[0053] In this embodiment, the position sensor 6 is based on electromagnetic induction to detect the change of the magnetic field to realize positioning, and is combined with the structure of the stomach and the intestine in the esophagus of the human body to be used for assisting in judging the depth and position of the gastrointestinal feeding tube. The pH sensor 7 is based on the electrochemical principle, and uses a glass electrode to measure the hydrogen ion concentration in the solution. When the sensitive part of the glass electrode contacts the solution in the gastrointestinal tract, the hydrogen ion will generate a potential difference between the electrode and the reference electrode. The potential difference is related to the pH value of the solution, and by measuring the potential difference, the pH value can be obtained to detect the acidity and alkalinity of the digestive juice at different positions in the digestive tract, and help to evaluate the gastric acid secretion and the local environment of the digestive tract.

[0054] The biochemical sensor 8 can adopt an enzyme electrode, an ion-selective electrode, or an optical sensing technology. The enzyme electrode uses the electrical signal generated by the specific enzyme catalytic reaction to measure the concentration of biological molecules; the ion-selective electrode can selectively detect the concentration of specific ions (such as sodium, potassium, and calcium); the optical sensing technology measures the concentration of chemical substances by detecting the absorption or fluorescence reaction of the biological sample to light; it can detect specific biomarkers such as lactic acid, glucose, protein decomposition products, and electrolyte levels to evaluate the metabolic state of the gastrointestinal tract.

[0055] The pressure sensor 9 is usually based on piezoelectric effect or capacitance change principle. The piezoelectric effect sensor generates an electric signal by applying pressure to a piezoelectric material; the capacitance type pressure sensor detects pressure change by measuring the change of capacitance caused by pressure. It is used to monitor the pressure in the gastrointestinal tract, evaluate the peristalsis and possible obstruction of the gastrointestinal tract, and thus help adjust the speed and amount of nutrient or drug delivery. The temperature sensor 10 is usually based on thermocouple or thermistor principle. Among them, the thermocouple measures temperature by the voltage difference generated at the contact point of two different metals; the thermistor detects temperature by the change of resistance with temperature, which can monitor the temperature of the environment around the pipeline, help judge the abnormal situation in the digestive tract, such as infection or inflammation, etc.

[0056] And the data processing unit 16 will transmit the processing results to the display 17 for display after processing each parameter by microprocessor, in order to assist the gastrointestinal nutrition tube to carry out infusion process; and the function and processing method of the data processing unit 16 can be adaptively selected and adjusted.

[0057] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
