Description

Technical Field

[0001] This invention relates to the field of gastric tubes, and more specifically to a gastric tube for assisting in gastric pressure monitoring and a monitoring method thereof. Background Technology

[0002] A gastric tube is used in special circumstances to help patients who cannot swallow to deliver necessary water and food. Gastric tubes are generally made of polyurethane or silicone. Depending on the material, polyurethane and silicone gastric tubes should be replaced every month. They come in different sizes and lengths and are divided into oral gastric tubes and nasogastric tubes.

[0003] Existing nasogastric tubes lack a fixed structure, making it impossible to secure the tube to the patient's nose. This causes the tube to slip easily, leading to patient discomfort. Furthermore, nasogastric tubes do not have the function of monitoring intragastric pressure. When medical staff need to check the intragastric pressure, they must remove the nasogastric tube and then insert a pressure-measuring catheter into the patient's stomach for testing. This procedure is cumbersome and increases patient pain.

[0004] Therefore, it is necessary to invent a gastric tube for assisting in gastric pressure monitoring and a monitoring method thereof. Summary of the Invention

[0005] Therefore, the present invention provides a gastric tube for assisting gastric pressure monitoring and a monitoring method thereof to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gastric tube for assisting gastric pressure monitoring, comprising a gastric tube body, a fluid guiding component disposed within the gastric tube body, two sets of catheter assemblies fixedly connected to the top of one side of the fluid guiding component, a gastric pressure monitoring component and a camera component disposed on the gastric tube body, and a fixing mechanism disposed on the upper part of the gastric tube body.

[0007] Preferably, the fluid guiding assembly includes channels symmetrically arranged on both sides of the gastric tube body. Each of the two sets of channels has a through hole at its bottom side. Each of the two sets of through holes has a unidirectional fluid guiding membrane fixedly arranged inside it. The top of each of the two sets of channels near the through hole is fixedly connected to the corresponding catheter assembly.

[0008] Preferably, the catheter assembly includes a catheter, a liquid guide tube is fixedly connected to the center of the bottom end of the catheter, a second magnetic ring is fixedly sleeved on the upper part of the catheter, a cap is slidably sleeved on the top of the catheter, the center of the top of the cap is fixedly connected to the middle of one side of the catheter by a rope, and a first magnetic ring is fixedly installed at the bottom end of the cap.

[0009] Preferably, the first magnetic ring and the second magnetic ring are configured with opposite magnetic properties, and the end of the liquid guide tube away from the conduit is fixedly connected to the top of the corresponding channel side.

[0010] Preferably, the gastric pressure monitoring component includes a miniature pressure sensor, which is fixedly installed on the bottom side of the channel. The miniature pressure sensor is electrically connected to a first USB cable via a first wire. The first wire is fixedly disposed in the inner wall of the gastric tube body. A first USB interface is provided at the end of the first USB cable away from the first wire, and the end of the first USB cable away from the first wire is slidably disposed in the first USB interface. A pressure gauge is electrically connected to the end of the first USB interface away from the first USB cable.

[0011] Preferably, the camera assembly includes a miniature camera and LED beads, and four sets of miniature cameras and LED beads are provided. The four sets of miniature cameras and four sets of LED beads are electrically connected to a second USB cable through a second wire. A second USB interface is provided at the end of the second USB cable away from the second wire, and the end of the second USB cable away from the second wire is slidably disposed in the second USB interface. A controller is electrically connected to the end of the second USB interface away from the second wire, and the controller is electrically connected to a display screen through a third wire.

[0012] Preferably, the four sets of miniature cameras and the four sets of LED beads are evenly fixedly installed on the four sides of the bottom of the gastric tube body, and the second wire is fixedly installed in the inner wall of the gastric tube body.

[0013] Preferably, the fixing mechanism includes an airbag, and a three-way pipe is fixedly connected to one end of the airbag via an air tube. A one-way valve is fixedly installed inside the top end of the three-way pipe. An annular plate is fixedly sleeved on the lower part of the three-way pipe. A sealing gasket is provided below the annular plate and is slidably sleeved on the three-way pipe. The outer surface of the bottom end of the three-way pipe is threaded, and a threaded sleeve is threadedly connected to the bottom end of the three-way pipe.

[0014] Preferably, the top and bottom of the sealing gasket are respectively fitted to the bottom of the ring plate and the top of the threaded sleeve, and the airbag is fixedly sleeved on the upper part of the gastric tube body.

[0015] A monitoring method, comprising the following methods;

[0016] Step 1: Medical staff insert the bottom end of the gastric tube into the patient's stomach through the nose;

[0017] Step 2: After the gastric tube is inserted to an appropriate length, the medical staff fixes the upper part of the gastric tube to the patient's nose using a fixing mechanism. The gastric tube cannot easily slide at the patient's nose, so that the gastric tube does not easily slide in the patient's stomach.

[0018] Step 3: The miniature pressure sensor in the gastric pressure monitoring component, which enters the patient's stomach along with the bottom of the gastric tube, can monitor the pressure in the patient's stomach in real time. The pressure value in the patient's stomach is displayed by the pressure gauge in the gastric pressure monitoring component.

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] See attached document Figure 1-6 The present invention provides a gastric tube for assisting gastric pressure monitoring and a monitoring method thereof, including a gastric tube body 1, a fluid guiding component disposed in the gastric tube body 1, two sets of catheter assemblies fixedly connected to the top of one side of the fluid guiding component, a gastric pressure monitoring component and a camera component disposed on the gastric tube body 1, and a fixing mechanism disposed on the upper part of the gastric tube body 1.

[0029] The fluid delivery assembly includes channels 2, which are symmetrically arranged on both sides of the gastric tube body 1. The two sets of channels 2 are used to draw gastric juice and deliver nasogastric feeding solution, respectively, thus making the gastric tube multifunctional. Both sets of channels 2 have through holes 3 connected to one side of their bottoms. One-way fluid delivery membranes 4 are fixedly installed in both sets of through holes 3. The one-way fluid delivery membranes 4 can conduct liquid on one side, thus making it difficult for gastric juice to enter the channel 2 that delivers nasogastric feeding solution. The top of the side of both sets of channels 2 near the through holes 3 is fixedly connected to the corresponding catheter assembly.

[0030] The conduit assembly includes a conduit 26, with a liquid guide tube 25 fixedly connected to the center of the bottom end of the conduit 26. A second magnetic ring 30 is fixedly sleeved on the upper part of the conduit 26, and a cap 28 is slidably sleeved on the top of the conduit 26. The cap 28 is used to block the upper part of the conduit 26, thereby preventing the top of the conduit 26 from being exposed to the outside and contaminated. The center of the top of the cap 28 is fixedly connected to the middle of one side of the conduit 26 by a rope 27, which makes the cap 28 less likely to be lost. A first magnetic ring 29 is fixedly installed at the bottom end of the cap 28. The first magnetic ring 29 and the second magnetic ring 30 are magnetically opposite. The cap 28 is installed on the conduit 26 by magnetic connection between the first magnetic ring 29 and the second magnetic ring 30. The end of the liquid guide tube 25 away from the conduit 26 is fixedly connected to the top of one side of the corresponding channel 2.

[0031] The gastric pressure monitoring component includes a miniature pressure sensor 5, which is fixedly installed on the bottom side of the channel 2. The pressure sensor 5 is used to monitor the pressure in the patient's stomach. The miniature pressure sensor 5 is electrically connected to a first USB cable 7 via a first wire 6. The first wire 6 is fixedly installed in the inner wall of the gastric tube body 1. The end of the first USB cable 7 away from the first wire 6 is provided with a first USB interface 8, and the end of the first USB cable 7 away from the first wire 6 is slidably installed in the first USB interface 8. Through the first USB interface 8 and the first USB cable 7, the pressure gauge 9 can be removed and reused after the gastric tube has been used. The end of the first USB interface 8 away from the first USB cable 7 is electrically connected to the pressure gauge 9, which is used to receive pressure information and display the pressure value in the patient's stomach.

[0032] The camera assembly includes miniature cameras 10 and LEDs 11, with four sets of each. The miniature cameras 10 capture images of the patient's stomach, while the LEDs 11 illuminate the stomach, allowing the miniature cameras 10 to clearly capture the internal conditions. All four sets of miniature cameras 10 and LEDs 11 are electrically connected to a second USB cable 13 via a second wire 12. A second USB interface 14 is located at the end of the second USB cable 13 furthest from the second wire 12, and this end slides within the second USB interface 14. The SB interface 14 and the second USB cable 13 allow the display screen 16 and controller 24 to be detached and reused after the gastric tube is used. The end of the second USB interface 14 away from the second wire 12 is electrically connected to the controller 24. The controller 24 is used to process the image information captured by the four miniature cameras 10. The controller 24 is electrically connected to the display screen 16 through the third wire 15. The display screen 16 is used to display the images captured by the four miniature cameras 10. The four miniature cameras 10 and the four LED beads 11 are evenly fixedly installed on the four sides of the bottom of the gastric tube body 1. The second wire 12 is fixedly installed in the inner wall of the gastric tube body 1.

[0033] The fixation mechanism includes an air bladder 17. A three-way tube 19 is fixedly connected to one end of the air bladder 17 via an endotracheal tube 18. The air bladder 17, when inflated, can fill the patient's nose, thus fixing the upper part of the gastric tube body 1 at the patient's nose, preventing the gastric tube body 1 from slipping and causing discomfort to the patient. A one-way valve 20 is fixedly installed inside the top of the three-way tube 19 to prevent gas leakage through the upper part of the three-way tube 19 when inflating the air bladder 17. The lower part of the three-way tube 19... A ring plate 21 is fixedly fitted, and a sealing gasket 22 is provided below the ring plate 21. The sealing gasket 22 is slidably fitted on the three-way tube 19. The sealing gasket 22 is used to seal the part between the ring plate 21 and the threaded sleeve 23 to prevent air leakage. The bottom end of the three-way tube 19 is threaded on its outer surface, and the bottom end of the three-way tube 19 is threadedly connected to the threaded sleeve 23. The top and bottom of the sealing gasket 22 are respectively fitted to the bottom of the ring plate 21 and the top of the threaded sleeve 23. The air bladder 17 is fixedly fitted on the upper part of the gastric tube body 1.

[0034] The usage process of this invention is as follows: During use, medical personnel insert the bottom end of the gastric tube body 1 into the patient's stomach through the nose. When the air bladder 17 enters the patient's nose, the medical personnel inflate the three-way tube 19 through the top of the three-way tube 19. At this time, the gas in the three-way tube 19 enters the air bladder 17 through the trachea 18, causing the air bladder 17 to inflate and fill the patient's nose. This fixes the upper part of the gastric tube body 1 at the patient's nose, making it less prone to slippage and thus avoiding discomfort caused by slippage. (Miniature pressure sensor) Device 5 can monitor the pressure inside the patient's stomach in real time. It transmits signals to pressure gauge 9 via the first lead wire 6, the first USB cable 7, and the first USB interface 8, displaying the pressure level within the patient's stomach. This allows the nasogastric tube to monitor stomach pressure in real time without requiring medical personnel to remove the tube and insert a pressure-measuring catheter, thus avoiding pain for the patient. When it is necessary to check the patient's stomach, four sets of LEDs 11 illuminate the stomach, and four miniature cameras 10 capture images of the stomach. These images are then transmitted via the second lead wire 12, the second USB cable 13, and the first USB interface 8. The second USB interface 14 transmits the captured image to the controller 24. The controller 24 processes the captured image and transmits it to the display screen 16 via the third wire 15 for display, allowing medical staff to see the patient's stomach condition in real time, greatly facilitating patient treatment. The gastric tube body 1 is equipped with two sets of channels 2, which are used for drawing gastric juice and delivering nasogastric feeding solution, respectively. When medical staff need to draw gastric juice or deliver nasogastric feeding solution, they can pull the corresponding cap 28 upwards, thereby disengaging the first magnetic ring 29 and the second magnetic ring 30 from their magnetic connection. Then, medical staff can remove the cap 28 from the catheter 26. They can then use the catheter 26, the fluid inlet tube 25, the channel 2, and the through hole 3 to draw gastric fluid or deliver nasogastric feeding solution. This allows the gastric tube to draw gastric fluid and deliver nasogastric feeding solution without requiring different procedures by inserting different tubes, greatly simplifying its use. When removing the gastric tube, medical staff only need to rotate the threaded sleeve 23 to remove it from the three-way tube 19. At this time, the gas in the cuff 17 will be released through the trachea 18 and the lower part of the three-way tube 19, thus releasing the fixation and allowing the gastric tube to be removed from the patient's stomach.

[0035] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
