Description

Technical Field

[0001] The present invention relates to the technical field of digestive tract monitoring, and in particular to a digestive tract bleeding monitoring system with enteral nutrition support function. Background Art

[0002] There are many causes of digestive tract bleeding. First, peptic ulcer: This is the most common cause of upper digestive tract bleeding, often occurring in the stomach and duodenum, mainly related to excessive gastric acid secretion, smoking, Helicobacter pylori infection, long-term use of drugs such as ibuprofen, etc. Second, rupture of esophageal and gastric varices: Commonly seen in middle-aged and elderly people with long-term alcoholism or those with severe liver diseases. Due to portal hypertension, the return of esophageal and gastric varices to the portal vein is blocked, resulting in blood vessel dilation and neovascularization. When the portal vein pressure rises to a certain level, the esophageal and gastric varices will rupture and bleed. Third, acute erosive hemorrhagic gastritis: Commonly seen in acute gastric mucosal injury or erosive bleeding. When patients experience severe trauma and mental stress, etc., it is easy to cause a stress response in the gastric mucosa, leading to damage of the mucosal barrier, erosion, bleeding, and ulcers. When the ulcer ruptures, hematemesis is likely to occur. Fourth, digestive tract tumors: Such as gastric cancer, esophageal cancer, etc. When the tumor grows to a certain size, it is easy to rupture, and partial necrosis can lead to bleeding when it occurs.

[0003] During the observation period after treatment of the digestive tract, in order to avoid the stimulation of food to the digestive tract bleeding site, enteral nutrition support is often used to meet the nutritional supply of patients. The main method is to insert a tubular body into the human intestine, such as nasogastric feeding. The tubular body is inserted from the nostril, passes through the esophagus to reach the stomach or intestine. The problem with the existing technology is that since the doctor also needs to constantly understand the situation of the digestive tract bleeding site during the insertion of the tubular body, a gastroscope is still needed to observe the internal bleeding site of the digestive tract when observing the bleeding site. Obviously, this method increases the catheterization times and pain of patients, and using a traditional gastroscope to observe the digestive tract bleeding site also cannot meet long-term monitoring. Based on the above situation, a digestive tract bleeding monitoring system with enteral nutrition support function needs to be set up to solve the above problems. Summary of the Invention

[0004] The present invention provides a digestive tract bleeding monitoring system with enteral nutrition support function, which realizes synchronous monitoring of whether the digestive tract bleeds during enteral nutrition support by setting sensors on a tubular body capable of providing nutritional support to the intestine and having a host device cooperating with the sensors.

[0005] The technical problems solved by the present invention are realized by the following technical solutions: The present invention provides a digestive tract bleeding monitoring system with enteral nutrition support function, including a tubular body. A channel for transporting nutrients with an input port and an output port is arranged inside the tubular body. The input port is arranged near one end of the tubular body left outside the human body, and the output port is arranged near one end of the tubular body left inside the human body. The system further includes a sensor arranged on the side wall of the part of the tubular body left inside the human body for monitoring the bleeding condition of the human digestive tract, and a host device. The input end of the host device is connected to the output end of the sensor. The data processing module inside the host device processes the data transmitted by the sensor to judge the bleeding condition inside the human digestive tract.

[0006] Preferably, the sensor arranged on the side wall of the part of the tubular body left inside the human body is an optical sensor, which judges the bleeding condition inside the digestive tract by monitoring the presence of hemoglobin or red blood cells in the intestine.

[0007] Preferably, the sensor arranged on the side wall of the part of the tubular body left inside the human body is an electrochemical sensor, which indirectly judges the bleeding condition inside the digestive tract by monitoring the change of the concentration of specific chemical substances inside the digestive tract.

[0008] Preferably, a display screen module for displaying the judgment result of the data processing module is arranged on the host device.

[0009] Preferably, a camera is arranged at one end of the tubular body left inside the human body, and the picture taken by the camera is displayed through the display screen module on the host device.

[0010] Preferably, a control module and an alarm module are further arranged on the host device. When the data processing module judges that there is bleeding inside the intestine after processing the data of the sensor, the control module controls the alarm module to work.

[0011] Preferably, a communication module is further arranged inside the host device, and the host device realizes data interaction with an external terminal through the communication module.

[0012] Preferably, the number of the output ports is multiple, and the multiple output ports are arranged on the side wall near one end of the tubular body left inside the human body.

[0013] Preferably, a valve is arranged on the input port. When the data processing module of the host device judges bleeding inside the digestive tract, the control module of the host device controls the valve on the input port to close.

[0014] Preferably, the number of sensors arranged on the side wall of the part of the tubular body left inside the human body is multiple, and the multiple sensors are arranged at intervals.

[0015] The beneficial effects of the present invention are as follows: By providing a sensor on the tubular body capable of providing nutritional support to monitor whether there is bleeding inside the digestive tract, and cooperating with the host device to process the data of the sensor, it is possible to know in real time whether there is bleeding inside the digestive tract, and this monitoring process is sustainable until the tubular body is removed from the human body, thereby reducing the number of catheter insertions and the pain of patients with digestive tract diseases.

[0016] By providing a camera at one end of the tubular body that remains inside the human body, it is possible to observe in real time through the display module of the host device the position where the tubular body is inserted into the human body, which is more convenient for the operation of the catheter insertion process.

[0017] By providing a valve at the channel inlet inside the tubular body, when the sensor detects bleeding in the digestive tract, the host device can immediately control the closing of the valve through the control module inside the host device to avoid accidental human operation for enteral nutrition supply.

Detailed implementation

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0022] For digestive tract diseases, such as esophageal cancer, gastric cancer, gastric ulcer, etc., after surgery, in order to avoid food irritating the digestive tract wound, enteral nutrition support is usually required to maintain the patient's nutritional supply. For example, Figure 1 In, which is a common enteral nutrition support method. Taking the esophagus 11 having a wound as an example, it is inserted into the human body through a nostril 10 by a tubular body 1 and reaches the stomach 12 of the human body through the esophagus 11. Nutrients can be injected from one end of the tubular body 1 through a syringe. The nutrients directly reach the stomach 12 of the human body through the channel 4 inside the tubular body 1, thus avoiding food contacting the wound on the esophagus 11 and causing bleeding due to wound irritation. Of course, if the position of the wound is in the stomach 12, the tubular body 1 needs to be extended to reach the duodenum 13 or jejunum 14 of the human body to achieve contact between the digestive tract wound position and food. This tubular body, as a temporary enteral nutrition support device, can be used once or can be retained in the human body for several days or weeks according to the patient's condition. For patients who need long-term enteral nutrition support, the tubular body 1 is often made of a material that can be retained for a long time, thus reducing the number of catheter insertions and pain. Existing enteral nutrition support has the following defects: it cannot monitor the easily bleeding positions inside the digestive tract. After the tubular body 1 needs to be removed, a gastroscope is used to observe the position of the digestive tract wound, which undoubtedly increases the number of catheter insertions and pain for the patient. At the same time, monitoring the internal wounds of the patient's digestive tract with a gastroscope is also temporary and cannot achieve continuous monitoring during enteral nutrition support. Based on this problem, a digestive tract bleeding monitoring system with enteral nutrition support function needs to be designed to solve the above problems.

[0023] Reference Figures 2 - 5 A digestive tract bleeding monitoring system with enteral nutrition support function provided by the present invention is provided. A sensor 9 is arranged on the side wall of the existing tubular body 1 capable of providing enteral nutrition support to monitor data inside the human intestine. At the same time, a host device 7 is arranged to be connected to the sensor 9 to receive the data of the sensor 9. The data processing module 701 inside the host device 7 processes the received data of the sensor 9 to judge whether there is bleeding inside the human intestine.

[0024] Furthermore, the above-mentioned sensor 9 can be an optical sensor 9 (such as a hemoglobin sensor 9), which monitors the presence of hemoglobin or red blood cells in the intestine and transmits the data to the host device 7. The host device 7 processes the data to determine whether there is bleeding in the intestine.

[0025] Furthermore, the above-mentioned sensor 9 can also be an electrochemical sensor 9, which monitors the change in the concentration of specific chemical substances inside the digestive tract (such as the change in Fe ion concentration), transmits the data to the host device 7, and thereby determines whether there is bleeding inside the digestive tract.

[0026] Furthermore, in order to facilitate personnel to observe in real time whether there is bleeding inside the digestive tract displayed by the host device 7, a display screen module 702 is also provided on the host device 7, through which personnel can conveniently observe in real time.

[0027] Furthermore, in order to facilitate personnel to send the tubular body 1 to the target position, such as the wound at the position of the esophagus 11, generally, the end of the tubular body 1 placed inside the human body needs to be placed in the stomach 12 to ensure that the nutrient supply avoids the wound at the esophagus 11. If the wound is in the stomach 12, then the end of the tubular body 1 needs to be placed in the duodenum 13 or the jejunum 14 of the human body to ensure that the nutrients avoid the wound in the stomach 12. Therefore, in order to facilitate the determination of the end position of the tubular body 1, a camera 8 is also provided at the end of the tubular body 1. The picture taken by the camera 8 can be displayed in real time through the display screen module 702 provided in the above-mentioned host device 7. At the same time, it should be further explained that the display screen module 702 can also be set as a touch screen to facilitate human-machine interaction.

[0028] Furthermore, in order to give an alarm reminder in time when the host device 7 determines that the digestive tract of the human body is in a bleeding state, a control module 704 and an alarm module 703 are also provided on the host device 7. When the data processing module 701 determines that the current human intestine is in a bleeding condition, the host device 7 controls the alarm module 703 to work through the control module 704 for reminder. At this time, the structure of the host device 7 not only includes the data processing module 701 and the display screen module 702, as Figure 8 shown, but also includes a control module 704 and an alarm module 703.

[0029] Furthermore, in order to notify medical staff in time when the host device 7 determines internal bleeding in the digestive tract, as Figure 9 shown, the host device 7 also has a communication module 705 inside, which can communicate with an external terminal, perform real-time data interaction, and notify medical staff in time.

[0030] Further, to facilitate the dispersion of nutrients inside the channel 4 when being discharged, an input port 2 is provided at one end of the tubular body 1 close to the end left outside the human body, and an output port 3 is provided at one end of the tubular body 1 close to the end left inside the human body. Nutrients are injected into the input port 2 through a syringe, and the nutrients are discharged from the output port 3 after passing through the channel 4. The output port 3 is provided on the side wall of the end of the tubular body 1 left inside the human body, and multiple output ports are provided, which can achieve the dispersion of nutrients and avoid accumulation.

[0031] Further, as Figure 10 shown, it is a schematic diagram of the electrical connection between the host device 7 and the external sensor 9 and the camera 8. The host device 7 can display the internal picture of the intestine by connecting with the camera 8. At the same time, in order to avoid others performing enteral nutrition support operations on the patient during gastrointestinal bleeding, that is, injecting food into the tubular body 1, a valve 15 is also provided at the position of the input port 2. The valve 15 is controlled by the control module 704 inside the host device 7. When the host device 7 determines that there is internal bleeding in the digestive tract, the control module 704 controls the valve 15 to close, thereby preventing enteral nutrition support operations.

[0032] Further, for patients with more than one wound position inside the digestive tract, multiple sensors 9 can be arranged at intervals on the side wall of the tubular body 1 to roughly judge the bleeding position in the digestive tract. Taking the hemoglobin sensor 9 mentioned above as an example, when there is internal bleeding in the digestive tract, the data monitored by the sensor 9 close to the bleeding position is larger, while the data detected by the sensor 9 far from the bleeding position in the digestive tract is smaller, or no data is detected. Therefore, by arranging multiple sensors 9 at intervals, the bleeding position inside the digestive tract can be roughly judged.

[0033] It should be further noted that the connection between the host device 7 and the camera 8 and the sensor 9 on the tubular body 1 is a wired connection. As Figure 6 and Figure 7 shown, a plug 6 connected by a wire is provided on the host device 7, and a socket 5 is provided at the end of the tubular body 1. The socket 5 is connected to the sensor 9 and the camera 8 through wires. When the plug 6 is connected to the socket 5, the host device 7 can obtain the data of the camera 8 and the sensor 9. Thus, during the process of a person getting out of bed and moving, the bleeding monitoring of the digestive tract can be cancelled by separating the plug 6 from the socket 5.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed.
