Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a gastrointestinal feeding tube that can monitor the pH value of the gastrointestinal tract. Background Technology

[0002] A gastrointestinal feeding tube is a tube inserted through the nose or mouth, passing through the pharynx and esophagus, and finally placed in the stomach or intestines. Through the gastrointestinal feeding tube, nutrients can be delivered directly to the stomach or intestines, ensuring that patients ingest sufficient protein, carbohydrates, fats, vitamins, and minerals, maintaining the body's nutritional status, and promoting physical recovery.

[0003] Currently, common types of nasoenteric tubes include: ordinary nasoenteric tubes and visual nasoenteric tubes. The former is characterized by its placement and feeding functions, serving only the purpose of feeding. Clinically, the tube's location cannot be clearly determined during placement, requiring auxiliary examinations such as X-rays and ultrasound. These examinations often necessitate interrupting feeding, increasing patient suffering and financial burden, as well as the workload of staff. The latter, visual nasoenteric tubes, allow for direct assessment during placement, but are expensive and cannot provide real-time monitoring during tube insertion. In cases of tube displacement due to coughing or vomiting in long-term patients, effective assessment is not possible. Furthermore, current enteral feeding tubes lack the function of pH monitoring in the gastrointestinal tract, indicating a certain degree of limitation.

[0004] Therefore, a gastrointestinal feeding tube that can monitor the pH value of the gastrointestinal tract is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention designs a gastrointestinal feeding tube capable of monitoring the pH value of the gastrointestinal tract. This tube can detect the pH value of the gastrointestinal tract and determine the position of the tube tip by detecting the pH, enabling precise tube placement. Furthermore, pH detection helps determine the state of the patient's stomach, guiding clinical medical staff to adjust the feeding route accordingly.

[0006] To achieve the above-mentioned technical effects, the present invention discloses a gastrointestinal feeding tube that can monitor the pH value of the gastrointestinal tract, comprising: a detection body and a gastrointestinal feeding tube; the side end of the detection body is connected to the gastrointestinal feeding tube, and a detection head is fixedly installed at the front end of the gastrointestinal feeding tube; The outer wall of the detection head has a circumferential array of liquid collection holes. Corresponding to the position of the liquid collection holes, a flushing tube is fixedly installed on the inner wall of the detection head. The upper end face of the inner side of the liquid collection hole is flat, and the lower end face is arc-shaped, with the arc-shaped lower end face inclined from the outside to the inside. At the same time, a probe is fixedly installed corresponding to the position of the liquid collection hole. The pH is monitored by the probe while the liquid is collected through the liquid collection hole.

[0007] Furthermore, the flushing pipe is provided with several liquid outlets at the lower end of the flushing head, and the liquid outlets are directly opposite the inner end face of the liquid collection hole. Furthermore, a rubber head is movably connected to the end of the rinsing head via a rotating shaft; both the rotating shaft and the rubber head are made of silicone. Furthermore, the upper end of the probe is connected to a transmission line, and the upper end of the transmission line extends to the outside through the gastrointestinal feeding tube. Furthermore, the side end of the detection body is provided with a signal hole for transmission line connection, and the front end of the detection body is provided with a display screen; Furthermore, the end of the gastrointestinal feeding tube furthest from the detection head is also fixedly connected to a nutrient addition head and a drug addition head for rinsing and drug addition, respectively.

[0008] The beneficial effects of this invention are: This invention designs a gastrointestinal feeding tube for monitoring the pH value of the gastrointestinal tract, comprising: a detection body and a gastrointestinal feeding tube; the side end of the detection body is connected to the gastrointestinal feeding tube, and a detection head is fixedly installed at the front end of the gastrointestinal feeding tube; The detection head allows for the measurement of pH levels in the gastrointestinal tract. To further ensure accurate detection, a circumferential array of liquid collection holes is arranged on the outer wall of the front end of the detection head. The upper surface of each collection hole is flat, while the lower surface is curved. This curved design allows for better collection of fluid from the gastrointestinal tract, ensuring accurate probe detection. A flushing tube is also included to flush the collection holes, effectively preventing blockage caused by prolonged retention of gastrointestinal tract tissue. This combination of flushing tube and detection head achieves both effective pH measurement and blockage prevention, making it convenient and practical. Attached Figure Description

Detailed Implementation

[0012] Example A gastrointestinal feeding tube 2 capable of monitoring gastrointestinal pH includes: a detection body 1 and a gastrointestinal feeding tube 2; the side end of the detection body 1 is connected to the gastrointestinal feeding tube 2, and a detection head 25 is fixedly installed at the front end of the gastrointestinal feeding tube 2; through the detection head 25, the pH value of digestive fluids in the gastrointestinal tract can be detected. According to literature reports, gastric juice is usually acidic, and intestinal juice is alkaline, with a normal gastric juice pH value of 3.0-5.0 and a normal small intestinal juice pH value of 5.8-7.5. This technology can, on the one hand, guide the patient to initially determine the position of the tube tip by real-time monitoring of the pH value at the tube tip; on the other hand, it can monitor the pH value of gastric or intestinal fluids in real time during the patient's tube insertion process to determine whether there is insufficient gastrointestinal motility, gastric retention, gastroparesis, etc., and guide medical staff to adjust the feeding plan in a timely manner. Furthermore, to further ensure the effectiveness of the detection... The outer wall of the detection head 25 has a circumferential array of collection holes 253. Corresponding to the positions of the collection holes 253, a flushing tube 211 is fixedly installed on the inner wall of the detection head 25. The upper surface of the inner side of the collection hole 253 is flat, and the lower surface is curved, with the curved surface of the lower surface sloping from the outside to the inside. Simultaneously, a probe 241 is fixedly installed corresponding to the positions of the collection holes 253. While collecting liquid through the collection holes 253, the probe 241 is used to monitor pH. The upper end of the probe 241 is connected to a transmission line 24, the upper end of which extends to the outside through the gastrointestinal feeding tube 2. The curved surface design allows for better retention of liquid in the gastrointestinal tract, ensuring the accuracy of the probe 241 detection. Simultaneously, the flushing tube 211 flushes the collection holes 253, effectively preventing blockage caused by prolonged retention of the gastrointestinal tract.

[0013] In this embodiment, in order to clean up the gastrointestinal contents accumulated in the collection hole 253, prevent blockage, and ensure the accuracy of pH detection during use, several outlets 2111 are provided at the lower end of the flushing pipe 211 and the outlets 2111 are directly opposite the inner end face of the collection hole 253; the flushing liquid injected into the flushing pipe 211 is used to flush it.

[0014] In this embodiment, the collection hole 253 is typically designed as a direct opening, and is cylindrical in shape. This allows for direct pH detection via the movement of the gastrointestinal feeding tube 2. While this method adapts to rapidly changing environments, the constantly changing liquid does not provide the probe 241 with an accurate detection environment or sufficient duration to ensure detection accuracy. (Since the stomach or intestines are constantly peristaltic, a cylindrical shape would inevitably cause liquid at the detection site or slippage of the cylinder, leading to accidental detection factors.) Therefore, this embodiment employs an arc-shaped collection hole 253. Specifically, the upper surface of the collection hole 253 is flat, while the lower surface is arc-shaped, with the arc-shaped lower surface sloping inwards. This arc-shaped design better retains the liquid in the gastrointestinal tract, ensuring accurate detection by the probe 241.

[0015] In addition, in this embodiment, the end of the rinsing head 21 is movably connected to a rubber head 252 via a rotating shaft 251; the rotating shaft 251 and the rubber head 252 are made of silicone; the rotating shaft 251 is connected in a way that allows it to rotate, and after rotation, it can deliver nutrient solution or nutrients. After delivery, the end can be sealed to prevent backflow.

[0016] Furthermore, in this embodiment, based on the aforementioned detection body 1, a signal hole 11 connected to the transmission line 24 is provided on the side end of the detection body 1 for establishing a signal connection with the transmission line 24. A display screen 12 is provided at the front end of the detection body 1 for observing the pH value fed back by the probe, which helps the doctor determine the current position of the gastrointestinal tube and facilitates adjustments. Simultaneously, a nutrient addition head 23 and a medication addition head 22 are fixedly connected to the end of the gastrointestinal feeding tube 2 furthest from the detection head 25 for rinsing and medication addition, respectively.

[0017] In addition, in this embodiment, the total length of the gastrointestinal feeding tube 2 is between 110-130 cm, and its length design can meet the physiological path requirements from the nasal cavity through the esophagus and stomach to the small intestine (upper jejunum). At the same time, the gastrointestinal feeding tube 2 is also equipped with a scale, which serves as a positioning mark for operation. By matching the physiological path from the human nasal cavity to the small intestine (the jejunum segment in adults usually requires 110-130 cm), the insertion depth can be precisely controlled. Quantitative depth control avoids insertion that is too deep (e.g., exceeding 130 cm, causing intestinal perforation) or too shallow (e.g., only reaching 50 cm, resulting in ineffective treatment), reducing the risk of mechanical damage to the digestive tract, reflux, aspiration, etc. It assists in the dynamic monitoring of tube displacement (e.g., comparing the initial and exposed scales to determine dislodgement) and, in conjunction with imaging examinations such as X-rays, quickly confirms the anatomical position of the tube end. It adapts to the differences in the digestive tract of adult patients with different body types, providing a basis for personalized depth adjustment for diseases such as gastroparesis. At the same time, the standardized scale guides the operation process, shortens the insertion time, and improves clinical standardization and patient comfort.
