Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a gastric tube for measuring abdominal pressure and an early warning system. Background Art

[0002] Intra-abdominal pressure (IAP) monitoring is crucial in critical care, postoperative management, and the diagnosis and treatment of digestive system diseases. Traditional methods rely on indirect measurement (such as cystometry), which has limitations such as complex operation, poor real-time performance, and inability to continuously monitor. In recent years, direct abdominal pressure measurement technology using a gastric tube has gradually developed, but existing technologies still have the following shortcomings:

[0003] Single monitoring function: Traditional gastric tubes only have drainage or drug administration functions. Although some products try to integrate pressure sensors, they lack coordinated monitoring with multimodal data such as temperature and imaging, making it difficult to comprehensively assess the state of the stomach. When the abdominal pressure exceeds the limit, it mostly relies on manual observation. There is a lack of active alarm function, making it difficult to intervene in time, which may delay the diagnosis of the disease.

[0004] Poor positioning stability: After insertion, the gastric tube is easily displaced due to factors such as changes in the patient's body position, gastrointestinal motility or coughing, causing the monitoring end to deviate from the target position and affecting data accuracy. Existing fixing methods (such as airbag inflation) require repeated adjustment of inflation and deflation, which is cumbersome and may damage the mucosa.

[0005] Low degree of automation: The insertion depth of the gastric tube depends on manual experience, and there is a lack of precise length control and delivery auxiliary devices, which can easily cause the insertion to be too deep or too shallow, increasing patient discomfort and the risk of complications.

[0006] Therefore, it is necessary to propose a gastric tube and early warning system for abdominal pressure measurement to solve the above problems. Summary of the Invention

[0040] Example 2

[0041] Please refer to Figures 1, 4, 5 and 8. This embodiment is further optimized on the basis of Example 1. Specifically, a gastric tube positioning mechanism 20 is provided on the outer side of the middle part of the gastric tube body 10. The gastric tube positioning mechanism 20 includes a fixing ring 21 fixed to the surface of the gastric tube body 10. The outer side of the fixing ring 21 is movably connected with a collar 22. The outer side of the collar 22 is fixedly connected with an air bag 23. One end of the air bag 23 is connected to the second air guide tube 30. A slide groove 24 is provided inside the collar 22.

[0042] In this embodiment, the second air pump is controlled by the second air pump knob switch 6, and the gas is transmitted through the second air duct 30 to supply air to the airbag 23, so that the gastric tube body 10 is fixed at the junction of the esophagus and the stomach; the suction function of the first air pump is controlled by the first air pump knob switch 5, and the gas is transmitted through the first air duct 29 to inflate or exhaust the piston cylinder 25, thereby controlling the position of the sealing piston 26, and the sealing piston 26 drives the slider 28 to move through the transmission rod 27, and the slider 28 drives the fixing ring 21 and then drives the gastric tube body 10 to move upward or downward. This function is used to fine-tune the position of the gastric tube body 10, and thereby adjust the position of the monitoring end 11; in this way, on the basis of ensuring that the airbag 23 is fixed to the gastric tube body 10, the position of the gastric tube body 10 can be adjusted without inflating or deflating the airbag 23.

[0043] Example 3

[0044] Referring to Figures 1, 6, 7 and 8, this embodiment is optimized as follows based on Example 1 or Example 2. Specifically, a conveying mechanism 40 is further provided on the outside of the gastric tube body 10. The conveying mechanism 40 includes a fixing box 41. A conveying channel 42 is provided in the middle of the fixing box 41. The gastric tube body 10 is located in the conveying channel 42. Transmission pulleys 46 are provided at the upper and lower ends of the conveying channel 42. A mounting slot 43 is provided inside the fixing box 41. Two rotating shafts 47 are symmetrically connected to the interior of the mounting slot 43 for rotation. A transmission gear 45 is fixedly connected to the outside of one end of the rotating shaft 47. The two transmission gears 45 are meshed and connected. The other end of the rotating shaft 47 is fixedly connected to the transmission pulley 46. A frequency conversion motor 44 is also fixedly connected to the interior of the mounting slot 43. The output shaft of the frequency conversion motor 44 is fixedly connected to one of the rotating shafts 47.

[0045] An infrared sensor 48 is provided at one end of the delivery channel 42; a reflective scale is provided on the surface of the gastric tube body 10, a data line is provided on the fixing box 41, and an interface connected to the data line is provided on the operating end 1, so that the infrared sensor 48 and the frequency conversion motor 44 are connected to the processor electrical signal, and data is input to the processor through the touch panel 4, and the processor controls the operation of the frequency conversion motor 44.

[0046] In this embodiment, by setting up a conveying mechanism 40, the gastric tube body 10 can be placed in the conveying channel 42, so that the gastric tube body 10 is located between the two transmission pulleys 46, and then the frequency conversion motor 44 is started, the frequency conversion motor 44 drives the transmission gear 45 to rotate, and the transmission gear 45 drives the transmission pulley 46 to rotate to convey the gastric tube body 10. When the gastric tube body 10 moves, the reflective scale reflects the light of the infrared sensor 48, and then the infrared sensor 48 is used to measure the conveying length of the gastric tube body 10, and the data is transmitted to the operating end 1. The processor receives the data from the infrared sensor 48, converts the data into a length dimension, and transmits it to the display screen 3.

[0047] Example 4

[0048] Please refer to Figure 6. This embodiment is based on Example 3 and is optimized as follows. Specifically, a groove 49 is opened on one side of the conveying channel 42. A spring 50 is fixedly connected to the inside of the groove 49. A baffle 51 is fixedly connected to the top of the spring 50. An operating panel 52 is fixedly connected to the outside of the baffle 51.

[0049] In this embodiment, a baffle 51 and a spring 50 are added to effectively prevent the gastric tube from escaping from the delivery channel 42 during the delivery process, thereby improving safety. The operating panel 52 controls the baffle 51 to enter and exit the groove 49 by compressing the spring 50. After the gastric tube is placed, the delivery mechanism 40 can be easily removed, simplifying the operation process. As an independent module, the delivery mechanism 40 can be compatible with the gastric tube body 10, retaining the original monitoring function while enhancing operational flexibility to meet the needs of different clinical scenarios.

[0050] In summary, the present invention monitors abdominal pressure in real time through the pressure sensor 12, and combines the temperature sensor 13, the micro camera 15 and the lighting lamp 16 to achieve multi-dimensional monitoring of gastric pressure, temperature and images, providing comprehensive data support for clinical practice. The touch panel 4 can preset the pressure threshold, and the processor automatically determines the over-limit situation and triggers the alarm 7 for early warning, avoiding the lag of traditional manual observation and reducing the risk of misjudgment. The monitoring data is transmitted to the operating terminal 1 through the data line 17, and is displayed on the display screen 3 in real time after being processed by the processor, so that medical staff can quickly grasp the patient's status. The micro camera 15 and the lighting lamp 16 can intuitively observe the stomach condition and assist in diagnosis or adjustment of the gastric tube position. The operating terminal 1 integrates the display screen 3, the touch panel 4 and the air pump knob switch, which simplifies the operation process and improves the efficiency of human-computer interaction.

[0051] A new gastric tube positioning mechanism 20 is added, which fixes the gastric tube at the junction of the esophagus and stomach by inflating the airbag 23, avoiding displacement of traditional gastric tubes due to peristalsis or coughing, and improving monitoring stability; the first air pump controls the inflation / evacuation of the piston cylinder 25 through the first air guide tube 29, driving the sealing piston 26 to drive the gastric tube body 10 to move up and down fine-tuning, achieving precise positioning of the monitoring end 11 without repeatedly inflating and deflating the airbag 23. The second air pump knob switch 6 independently controls the inflation amount of the airbag 23, and the first air pump knob switch 5 is dedicated to position fine-tuning. The clear division of labor avoids operational conflicts. The sliding connection design of the collar 22 and the fixing ring 21 ensures that the gastric tube can still be flexibly adjusted when the airbag 23 is fixed, taking into account both stability and adaptability.

[0052] The conveying mechanism 40 drives the transmission gear 45 and the transmission pulley 46 through the frequency conversion motor 44 to realize the automatic pushing of the gastric tube body 10, reducing the error and operation difficulty of manual insertion. The infrared sensor 48 combines with the reflective scale on the surface of the gastric tube to measure the conveying length in real time and feedback to the display screen 3, ensuring that the monitoring end 11 accurately reaches the target position such as the fundus of the stomach, improving the monitoring accuracy. The conveying channel 42 adopts a double pulley clamping design and is synchronously driven with the transmission gear 45 to avoid twisting or jamming of the gastric tube and ensure a smooth conveying process. The data cable connects the infrared sensor 48 and the operating end 1 to realize real-time transmission and processing of length data, enhancing the intelligence level of the system.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
