Description

Technical Field

[0001] The present disclosure relates to the field of intelligent medical technologies, and particularly to a nasal-gastric tube visualization detection device, a system, a control method thereof, and an electronic device. Background Art

[0002] A nasal-gastric tube is a catheter that is inserted from the nasal cavity through the esophagus into the stomach, through which enteral nutrition can be administered or gastric decompression can be performed. The nasal-gastric tube mainly consists of a connector (head end), a flexible hose, a gastric tube feeding port connector, a gastric tube clamp, a cross-knot plug, a stainless steel guide wire (some specifications of the catheter do not contain a guide wire), etc. Among them, the guide wire is used to support the flexible hose.

[0003] The operation process of the nasal-gastric tube mainly includes the following points:

[0004] First, before catheterization, fully inform the patient or family members of the importance and necessity of inserting the nasal-gastric tube. After obtaining the trust and understanding of the patient or family members, it is convenient for the smooth operation of the nasal-gastric tube; evaluate the patient's condition and abdominal signs, and ask about any nasal diseases.

[0005] Second, instruct the patient to relax, clean the nasal cavity, take a suitable lying position, evenly apply paraffin oil to the head end of the nasal-gastric tube, and then slowly insert it into one nostril of the patient.

[0006] Third, the patient will initially experience discomfort symptoms. Instruct the patient to relax and take deep breaths. When the nasal-gastric tube reaches the epiglottis, instruct the patient to perform a swallowing action, or give the patient a small amount of warm water to assist the nasal-gastric tube to smoothly enter the esophagus.

[0007] Fourth, once the nasal-gastric tube enters the esophagus, the insertion speed can be appropriately increased, and instruct the patient to continuously perform swallowing actions. The insertion scale of the adult nasal-gastric tube is about 45-55 cm. During catheterization, the operator should adjust according to the individual differences of the patient. After inserting the appropriate scale, stop the operation and fix the nasal-gastric tube to prevent it from falling off.

[0008] However, during the process of inserting the head end of the nasal-gastric tube from the nostril to the esophagus, the movement may be affected due to lack of experience or the patient's discomfort, resulting in failed catheterization; moreover, during the catheterization process, the operator does not know whether there is an obstruction at the position passed by the head end and whether the orientation of the head end needs to be adjusted. Therefore, catheterization often causes the patient to be more uncomfortable and even damages the throat. Summary of the Invention

[0059] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. Like reference numerals in the drawings denote functionally identical or similar elements. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0060] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments.

[0061] In addition, for a better description of the present disclosure, numerous specific details are given in the following detailed description. Those skilled in the art should understand that the present disclosure can be implemented without some of these specific details. In some instances, well-known means, elements, and circuits have not been described in detail so as to highlight the gist of the present disclosure.

[0062] Embodiment 1

[0063] By using an electronic laryngoscope, the nasal gastric tube and the electronic laryngoscope are combined to realize the visualization operation of the intubation of the nasal gastric tube for the patient, and the intubation process and the nasal gastric endoscope image of the patient can be visually displayed on the LED monitor, which is convenient for guiding the doctor to smoothly perform the intubation.

[0064] As Figure 1 shown in the electronic laryngoscope, the main body of the electronic laryngoscope includes a handle 2, a visualization terminal 1 (monitor), and a detection hose (which is replaced by a nasal gastric tube in this embodiment). The detection hose is integrated with an endoscopic light source and the CCD imaging module, and can collect image data of the corresponding part under cold light irradiation by the CCD camera and send it to the visualization terminal for image processing and display.

[0065] Input keys (input module) for controlling the endoscopic light source and the CCD imaging module are provided on the visualization terminal, and when the doctor holds the handle for operation, the corresponding keys can be pressed to input the corresponding working parameters into the internal control chip.

[0066] Therefore, in this solution, the electronic laryngoscope is combined with the nasal gastric tube to realize the visualization inspection of the nasal cavity, stomach, throat, and esophagus during nasogastric intubation, display the nasal gastric endoscope visualization image on the visualization terminal, guide the operator to perform intubation, avoid damaging the inner wall of the patient's nasal cavity and stomach, and smoothly perform intubation.

[0067] In this solution, the proposed visual endoscope adopts the principle and function of the above-mentioned electronic laryngoscope.

[0068] In specific implementation, each nasogastric tube needs to be installed at the tail of the handle 3 through a fixing member (the fixing member is, for example, a mounting sleeve that can sleeve the nasogastric tube). At the head end of the nasogastric tube, an endoscopic light source and the CCD camera module need to be integrated (data is transmitted to the visualization terminal through a data cable, and the endoscopic light source and the CCD camera module are powered by the data cable).

[0069] For nasogastric tubes of different models, a set of endoscopic light source and CCD camera module need to be integrated on each of them. They are integrally installed at the head of the nasogastric tube. Specifically, reference can be made to the endoscopic light source and CCD camera module of an electronic laryngoscope for integration and design use. This embodiment does not make any limitations.

[0070] In this solution, the endoscopic light source and the CCD camera module need to be electrically connected to the chip inside the visualization terminal through a data cable. Therefore, by using the data cable, the endoscopic light source and the CCD camera module are connected through the data cable.

[0071] As Figure 2 shown, specifically, the data cable is wrapped in a corrosion-proof material inside a guide wire, passes through the guide wire inside the hose of the nasogastric tube 5, and ends with a data plug 6 at the tail. When in use, the data cable on the nasogastric tube is plugged into the data socket at the tail of the handle 3 through the data plug 6 (the data socket is connected to the visualization terminal through a data cable passing through the inside of the handle), so as to realize the data connection and communication between the endoscopic light source and the CCD camera module (the camera integration module 4, which integrates the endoscopic light source and the CCD camera module) on nasogastric tubes of different models and the visualization terminal.

[0072] When it is necessary to replace different nasogastric tubes, after replacement, the data plug 6 on the replaced nasogastric tube can be plugged into the data socket at the tail of the handle 3, so as to realize different plug-in uses.

[0073] Therefore, by adopting the above method, in the ward, only one or a few visualization terminals need to be configured. By replacing nasogastric tubes of different models, the visual nasogastric feeding of patients of different models can be realized, greatly saving the hardware cost.

[0074] On the one hand, the present application proposes a visual inspection device for a nasogastric tube, including:

[0075] A nasogastric tube;

[0076] A visual endoscope, and the nasogastric tube is installed on the visual endoscope in a supporting manner;

[0087] As an optional implementation solution of the present application, optionally, the visualization terminal is further used for:

[0088] Adjusting the working parameters of the endoscope light source and the CCD imaging module.

[0089] Specifically, different working parameters are input through the input keys on the visualization terminal.

[0090] As an optional implementation solution of the present application, optionally, the endoscope light source and the CCD imaging module are respectively electrically connected to the visualization terminal through a data cable, and the data cables are all wrapped in a wire inside the nasogastric tube hose through an anti-corrosion material.

[0091] In the application of this solution, if it is necessary to check the condition of the stomach, the wire with the data cable can be inserted again.

[0092] Because after the gastric tube is inserted, the wire is removed after taking an X-ray to determine the position, or for a gastric tube with imaging, the wire is removed after insertion and then an X-ray is taken to confirm. According to the above requirements, the wire in this solution can be inserted or removed at any time as needed.

[0093] For the final treatment of the wire, it can be retained or discarded by the patient's family member.

[0094] The guide wire of this solution can be reused. After disinfection, it can be reused, and the gastric tube is replaced each time; or the guide wire can be independently integrated and set in each gastric tube. This solution does not make specific limitations.

[0095] As an optional implementation of this application, optionally, one end of the data cable is respectively connected to the endoscopic light source and the CCD imaging module, and the other end is connected to the visualization terminal through the structure of a data plug.

[0096] As an optional implementation of this application, optionally, the visual endoscope further includes:

[0097] A data socket for connecting the data cables of the endoscopic light source and the CCD imaging module;

[0098] The data socket is provided at the tail end of the handle;

[0099] If it is necessary to replace the nasogastric tube of a different model, the data plug on the replaced nasogastric tube is plugged into the data socket at the tail end of the handle, so as to realize that the endoscopic light source and the CCD imaging module are respectively electrically connected to the visualization terminal in a plug-in manner.

[0100] As Figure 3 shown, as an optional implementation of this application, optionally, the visualization terminal includes:

[0101] An FPGA imager for image conversion processing;

[0102] An LED display for displaying the visualization image of the nasogastric endoscope;

[0104] A storage module for storing the image data of the nasogastric endoscope;

[0105] A power supply module for power supply;

[0106] An MCU control chip for controlling the logical work and data processing of the endoscopic light source, the CCD imaging module, the FPGA imager, the LED display, the input module, the storage module and the power supply module;

[0107] The endoscopic light source, the CCD imaging module, the FPGA imager, the LED display, the input module, the storage module and the power supply module are respectively electrically connected to the MCU control chip.

[0108] The specific application hardware of each of the above modules is not limited in this embodiment, and can be selected as long as it meets the functions of this solution.

[0109] For the functions of the above visualization terminal, please refer to the principle description and usage of the above electronic laryngoscope and nasogastric tube for understanding, and details will not be elaborated here.

[0110] The device also has specific data communication functions. It can transmit nasogastric endoscope image data (generating visual images of nasogastric feeding for each patient in the background for nasogastric feeding monitoring) to the background server through a data interface for the background staff to view and monitor. During nasogastric feeding, the attending doctor can remotely supervise the nurse's operation, which is determined according to the duration; or if necessary, it can stay at the end for a long time.

[0111] The background staff can judge whether there are any problems with the nasogastric feeding of each patient through nasogastric feeding monitoring and can intervene in treatment in a timely manner.

[0117] The background server can insert a data cable into the data interface of the visualization terminal to share the nasogastric endoscope image data with the visualization terminal for convenient nasogastric feeding monitoring.

[0118] Therefore, by adopting the method of an electronic laryngoscope, the present application combines the nasogastric tube and the electronic laryngoscope to realize the visualization operation of the catheterization of the nasogastric tube for patients. It can visually display the catheterization process and the nasogastric endoscope images of the patients on the LED display, which is convenient for guiding the operator to smoothly perform catheterization, judging whether there are obstacles at the catheterization site, timely adjusting the catheterization orientation and strength, etc., avoiding causing greater catheterization pain to the patient, avoiding the occurrence of esophageal inner wall damage caused by chaotic catheterization due to ignorance of the nasogastric conditions, and reducing the catheterization risk.
