Description

Technical Field

[0001] This invention relates to the field of nursing aids technology, specifically to an automatic oral care machine for patients with endotracheal intubation. Background Technology

[0002] Currently, oral care for intubated patients relies primarily on manual operation. Specifically, nurses use cotton balls soaked in saline solution to manually wipe the patient's mouth. Furthermore, simple irrigation and suction devices require step-by-step operation, making the process cumbersome. While existing automated equipment improves efficiency to some extent, it can only perform single-function irrigation or suction according to fixed parameters, failing to achieve simultaneous irrigation and suction. This step-by-step approach not only increases the risk of aspiration but also makes parameter settings arbitrary, unable to be flexibly adjusted according to the patient's specific condition. The intensity and effectiveness of nursing care largely depend on the nurse's personal experience, lacking scientific methods for quantitatively assessing oral condition. Existing equipment also cannot effectively avoid the endotracheal tube's position, causing interference and further increasing the complexity and risk of nursing care. Therefore, we propose an automated oral care machine for patients with endotracheal intubation via orotracheal intubation. Summary of the Invention

[0003] The purpose of this invention is to address the problems arising from the current step-by-step oral care procedures for patients with endotracheal intubation. These procedures not only increase the risk of fluid aspiration but also lead to arbitrary parameter settings that cannot be flexibly adjusted according to the patient's specific condition. The intensity and effectiveness of nursing care largely depend on the nurse's personal experience, lacking scientific methods for quantitatively assessing oral health. Existing equipment also cannot effectively avoid the location of the endotracheal tube during use, causing interference and further increasing the complexity and risk of nursing care. This invention provides an automated oral care machine for patients with endotracheal intubation via orotracheal intubation.

[0004] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0005] An automated oral care machine for patients undergoing endotracheal intubation includes a main unit housing a dual-channel pump control system and a main control module. The main unit housing also houses an oral retractor with image acquisition capabilities and a coaxial dual-lumen catheter irrigation module. The oral retractor with image acquisition capabilities includes an elastic retractor frame with side silicone brackets fixedly connected to both sides. An image acquisition camera is fixedly connected to the upper center of the elastic retractor frame via a flexible, shape-adjustable hose. The image acquisition camera integrates a near-infrared camera and a ring-shaped LED supplemental light. The coaxial dual-lumen catheter irrigation module includes an outer irrigation tube for delivering irrigation fluid and a central negative pressure suction inner tube for simultaneously aspirating irrigation fluid and oral secretions. The main control module controls the operation of the dual-channel pump control system based on image information acquired by the oral retractor with image acquisition capabilities.

[0006] Furthermore, the dual-channel pump control system includes a brine extrusion electric push rod and a negative pressure suction pump. A square through hole is opened at the center of the upper end of the main unit, and a brine extrusion groove is fixedly connected to the bottom of the square through hole. An extrusion plate is movably inserted into the bottom of one side of the brine extrusion groove. The brine extrusion electric push rod is fixedly installed inside the main unit, and the output push rod of the brine extrusion electric push rod is fixedly connected to the outer center of the extrusion plate. The bottom of the flushing outer tube is fixedly connected to a brine connector through an infusion hose, and the infusion hose passes through the brine extrusion groove and is positioned at the upper part of the inner cavity of the brine extrusion groove. A square slot is opened at the bottom of the front side of the main unit, and a sewage tank is inserted and fixedly installed in the square slot. The negative pressure suction pump is fixedly installed inside the main unit on the upper side corresponding to the sewage tank, and the suction port of the negative pressure suction pump is connected to the bottom of the negative pressure suction inner tube through a pipe. A sewage discharge connector is fixedly connected to the upper end of the square slot at the bottom of the main unit, and the discharge port of the negative pressure suction pump is connected to the sewage discharge connector. A sewage inlet is opened at the upper back side of the sewage tank corresponding to the sewage discharge connector.

[0007] Furthermore, the main control module includes an endotracheal intubation positioning unit. This unit uses a YOLOv5 model to identify the intubation position in real time, outputting the intubation center coordinates (x, y) and outer diameter D, according to formula S. safe =0.8D+3mm to generate a safe operating area and generate a mask image to ensure that the cannulation area is excluded in subsequent analysis and to avoid misidentification.

[0008] Furthermore, the main control module (24) also includes a nursing parameter dynamic mapping unit, which calculates the coverage ratio of dirt in the effective mucosal area through an image processing algorithm. The calculation formula is as follows:

[0009]

[0010] Among them, P contam (i) represents the dirt pixel, P mucosa(j) represents the effective coating area pixels. Coverage is used to quantify the degree of oral contamination. Based on the contamination coverage, rinsing parameters are dynamically generated and executed by an electric pump system.

[0011] Furthermore, the mapping logic of the dynamic mapping unit for nursing parameters is as follows:

[0012] When Coverage < 0.15: Set to mild care mode, with a flushing flow rate of 8 ml / s and a duration of 30 seconds;

[0013] When 0.15≤Coverage<0.4: activate the medium care mode, with a rinsing flow rate of 15ml / s, and activate the 0.5Hz pulse rinsing mode, that is, perform a pulse rinsing every 2 seconds, with each pulse lasting 1 second, to improve the cleaning effect;

[0014] When Coverage ≥ 0.4: Set to intensive care mode, with a flushing flow rate of 20 ml / s, and a suction power compensation coefficient K = 1.2, which means the suction pump power is increased by 20% to ensure that a large amount of flushing fluid and secretions can be suctioned out in time.

[0015] Furthermore, the main control module also includes a pump control unit, which controls the brine extrusion electric push rod and the negative pressure suction pump respectively. The brine extrusion electric push rod adopts flow closed-loop control with an accuracy of ±1ml / s. The negative pressure suction pump adopts negative pressure closed-loop control and adjusts the suction power in real time according to the flushing flow rate to ensure that the flow ratio is maintained at 1:1.05±0.03 to prevent liquid residue.

[0016] Furthermore, a digital display screen is fixedly connected to the outer side of the center of the elastic expansion frame, and a catheter fixing clamp is fixedly connected to the inner side of the center of the elastic expansion frame. A fixing bracket is fixedly connected to the upper end of the main unit, and the fixing bracket matches the oral cavity expander with image acquisition.

[0017] Furthermore, the coaxial dual-lumen catheter flushing module also includes a flushing head. The flushing head has multiple flushing nozzles evenly distributed at the end away from the flushing outer tube. All flushing nozzles are connected to the area between the negative pressure suction inner tube and the flushing outer tube through channels in the side wall of the flushing head. A pressure sensor suction seat is embedded in the center of the flushing head, and a suction nozzle is opened on the side wall of the pressure sensor suction seat. The pressure sensor suction seat is connected to the inner cavity of the negative pressure suction inner tube, and the suction nozzle on the side wall of the pressure sensor suction seat penetrates the flushing head.

[0018] Furthermore, the two ends of the elastic support frame are symmetrically provided with fixing holes, and two connecting mushroom heads are symmetrically fixedly connected to the side of the side silicone card holder facing the elastic support frame. The connecting mushroom heads are inserted and fixed one-to-one with the fixing holes.

[0019] Furthermore, an operation panel is fixedly installed on the top of the main unit, and the operation panel is equipped with a touch screen and multiple operation buttons. The touch screen and multiple operation buttons are electrically connected to the main control module, and the main control module is connected to the mains power supply via a power cord.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention integrates an oral retractor with image acquisition and a coaxial double-lumen catheter irrigation module, combined with intelligent control of the main control module, to achieve simultaneous irrigation and suction operations. This innovative design not only simplifies the operation process and reduces the risk of fluid aspiration, but also makes parameter settings more scientific and reasonable, allowing for flexible adjustments based on the patient's specific condition.

[0022] 2. This invention, through the design of a saline extrusion electric pusher and a negative pressure suction pump, can provide stable rinsing fluid flow and negative pressure suction respectively, ensuring effective rinsing and suction during oral care. The saline extrusion electric pusher is driven by a servo motor, which not only has a wide adjustable range of pushing speed but also high precision in pushing distance, meeting the rinsing needs of different care modes. The negative pressure suction pump is also driven by a servo motor, with an adjustable negative pressure range, allowing for flexible adjustment of suction power according to actual care conditions, ensuring that rinsing fluid and oral secretions can be suctioned out promptly and effectively.

[0023] 3. The application of the dynamic mapping unit for nursing parameters in this invention makes the oral care process more intelligent and personalized. By accurately calculating the coverage ratio of debris in the effective mucosal area, the system can assess the contamination status of the oral cavity in real time. This calculation formula not only considers the area of ​​debris but also compares it with the effective mucosal area, thus obtaining a more accurate debris coverage rate. Based on this coverage rate, the system automatically adjusts rinsing parameters, such as the flow rate, pressure, and duration of the rinsing solution, to ensure maximum rinsing effect while avoiding unnecessary irritation or harm to the patient. The execution of the electric pump system further ensures the precise implementation of the rinsing parameters, making the entire oral care process more efficient and safer.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Please see Figures 1-4 This invention provides an automatic oral care machine for patients with endotracheal intubation, comprising a main unit 1, which houses a dual-channel pump control system and a main control module 24. The main unit 1 also includes an oral retractor with image acquisition and a coaxial dual-lumen catheter irrigation module. The oral retractor with image acquisition includes an elastic retractor frame 2, with side silicone brackets 3 fixedly connected to both sides of the elastic retractor frame 2. An image acquisition camera 5 is fixedly connected to the upper center of the elastic retractor frame 2 via a flexible, shaping hose 4. The image acquisition camera 5 integrates a near-infrared camera and a ring LED supplemental light. The coaxial dual-lumen catheter irrigation module includes an outer irrigation tube 10 for delivering irrigation fluid and a central negative pressure suction inner tube 9 for simultaneously aspirating irrigation fluid and oral secretions. The main control module 24 controls the operation of the dual-channel pump control system based on the image information acquired by the oral retractor with image acquisition.

[0032] Nursing machine operation procedure:

[0033] Preparation phase: Nursing staff open the patient's mouth, secure the oral care device, and ensure the camera module and double-lumen catheter are in place. After the system is started, the camera module automatically acquires oral images (including visible light and near-infrared images).

[0034] Evaluation Phase: The main control module 24 processes the image: It uses the HSV color space to segment and identify contaminated areas. Noise is removed through morphological processing. The contaminated coverage is calculated. Based on the coverage value, the system automatically generates care parameters (such as flow rate, mode, etc.) and displays the plan on the control panel.

[0035] Execution Phase: After confirming the parameters, the nursing staff initiates the nursing procedure. The electric pump system begins operation: saline solution is expelled through the electric plunger 19 at a set flow rate, such as 15 ml / s, and sprayed through the flushing head 11. Simultaneously, the suction pump draws out fluid and waste through the central channel at a slightly higher flow rate, such as 15.75 ml / s. During the nursing process, images are re-acquired and parameters are adjusted every 5 seconds; the flow rate is reduced as waste decreases.

[0036] Safety monitoring: The system monitors the cannula position and flushing pressure throughout the procedure. Flushing is paused if the cannula displacement exceeds 2mm, and the flushing is stopped if the flushing pressure exceeds 25kPa. After the procedure, the system automatically records before-and-after image comparisons and parameters for medical staff to review.

[0037] By integrating an oral retractor with image acquisition and a coaxial dual-lumen catheter irrigation module, combined with the intelligent control of the main control module 24, simultaneous irrigation and suction operations are achieved. This innovative design not only simplifies the operation process and reduces the risk of fluid aspiration, but also makes parameter settings more scientific and reasonable, allowing for flexible adjustments based on the patient's specific condition. The endotracheal intubation positioning unit in the main control module 24 identifies the intubation position in real time using an advanced YOLOv5 model and generates a safe operating area, effectively avoiding interference with the endotracheal tube during nursing care, further reducing the complexity and risk of nursing work. The nursing parameter dynamic mapping unit can dynamically generate irrigation parameters based on the soil coverage rate calculated by the image processing algorithm, and execute them precisely through the electric pump system. This function not only improves the oral cleaning effect but also realizes the personalization and refinement of the nursing process. The saline extrusion electric push rod 19 and the negative pressure suction pump 21 in this invention both adopt closed-loop control, ensuring precise adjustment of irrigation flow and suction power, effectively preventing fluid residue, and further improving the quality and safety of nursing care.

[0038] In this embodiment, preferably, the dual-channel pump control system includes a saline extrusion electric push rod 19 and a negative pressure suction pump 21. A square through-hole is formed at the center of the upper end of the main unit 1, and a saline extrusion groove 16 is fixedly connected to the bottom of the square through-hole. A squeezing plate 20 is movably inserted into the bottom of one side of the saline extrusion groove 16. The saline extrusion electric push rod 19 is fixedly installed inside the main unit 1, and the output push rod of the saline extrusion electric push rod 19 is fixedly connected to the outer center of the squeezing plate 20. The bottom of the flushing outer tube 10 is fixedly connected to a saline connector 18 via an infusion hose, and the infusion hose passes through the saline extrusion groove 16 and is positioned near the upper part of the saline extrusion groove 16's inner cavity. A square slot is formed at the bottom front side of the main unit 1, and a wastewater tank 17 is fixedly inserted into the square slot. The negative pressure suction pump 21 is fixedly installed inside the main unit 1 on the upper side corresponding to the wastewater tank 17. The suction port of pump 21 is connected to the bottom of the negative pressure suction inner tube 9 via a pipe. A drain plug 22 is fixedly connected to the upper end of the square slot at the bottom of the main unit 1, and the outlet of the negative pressure suction pump 21 is connected to the drain plug 22. A wastewater inlet 23 is provided on the upper back side of the wastewater tank 17 corresponding to the drain plug 22. A bag of saline solution is placed into the saline squeezing tank 16, and then the opening of the saline bag is connected to the saline connector 18. The main control module 24 in the main unit 1 drives the saline extrusion electric push rod 19 to extend and retract, thereby driving the squeezing plate 20 to squeeze the saline bag, squeezing the saline solution into the rinsing outer tube 10, and then pressurizing and spraying it out to rinse the patient's oral cavity. The saline extrusion electric push rod 19 and the negative pressure suction pump 21 provide stable rinsing fluid flow and negative pressure suction, ensuring effective rinsing and suction during oral care. The saline extrusion electric push rod 19 is a servo motor-driven electric push rod, which not only has a wide adjustable speed range but also high precision in pushing distance, meeting the rinsing needs of different care modes. The negative pressure suction pump 21 is also driven by a servo motor, and the negative pressure range is adjustable. It can flexibly adjust the suction power according to the actual nursing situation to ensure that the rinsing fluid and oral secretions can be suctioned out in a timely and effective manner.

[0039] In this embodiment, preferably, the main control module 24 includes an endotracheal intubation positioning unit. The endotracheal intubation positioning unit identifies the intubation position in real time using the YOLOv5 model, outputs the center coordinates (x, y) and outer diameter D of the intubation tube, and calculates the position according to formula S. safeA safe operating area of ​​0.8D + 3mm is generated, along with a mask image to ensure the exclusion of the intubation area in subsequent analysis, avoiding misidentification. The endotracheal tube positioning unit accurately monitors the position of the endotracheal tube within the patient's mouth. The YOLOv5 model, as an advanced real-time object detection algorithm, features high accuracy and rapid response, enabling it to quickly identify the intubation location and output the tube's center coordinates and outer diameter information in real time. Based on this information, the system automatically calculates the safe operating area, which is defined around the intubation tube to ensure that all tools and equipment will not accidentally touch or damage the tube during oral care procedures, thus guaranteeing patient safety. Simultaneously, the generated mask image further excludes the intubation area in subsequent analysis, effectively avoiding potential risks caused by misidentification. This design not only improves the accuracy and safety of oral care but also significantly reduces the workload of medical staff.

[0040] In this embodiment, preferably, the main control module 24 further includes a nursing parameter dynamic mapping unit, which calculates the coverage ratio of dirt in the effective mucosal area through an image processing algorithm. The calculation formula is as follows:

[0041]

[0042] Among them, P contam (i) represents the dirt pixel, P mucosa (j) represents the effective coating area pixels. Coverage is used to quantify the degree of oral contamination. Based on the contamination coverage, rinsing parameters are dynamically generated and executed by an electric pump system.

[0043] The application of a dynamic mapping unit for nursing parameters makes oral care more intelligent and personalized. By accurately calculating the coverage ratio of debris in the effective mucosal area, the system can assess the contamination status of the oral cavity in real time. This calculation formula not only considers the area of ​​debris but also compares it with the effective mucosal area, thus obtaining a more accurate debris coverage rate. Based on this coverage rate, the system automatically adjusts rinsing parameters, such as the flow rate, pressure, and duration of the rinsing solution, to ensure maximum rinsing effectiveness while avoiding unnecessary irritation or harm to the patient. The execution of the electric pump system further ensures the precise implementation of rinsing parameters, making the entire oral care process more efficient and safer. This design not only improves the quality of oral care but also reflects respect and care for individual patient differences.

[0044] In this embodiment, preferably, the mapping logic of the nursing parameter dynamic mapping unit is as follows:

[0045] When Coverage < 0.15: Set to mild care mode, with a flushing flow rate of 8 ml / s and a duration of 30 seconds;

[0046] When 0.15≤Coverage<0.4: activate the medium care mode, with a rinsing flow rate of 15ml / s, and activate the 0.5Hz pulse rinsing mode, that is, perform a pulse rinsing every 2 seconds, with each pulse lasting 1 second, to improve the cleaning effect;

[0047] When Coverage ≥ 0.4: Set to intensive care mode, with a flushing flow rate of 20 ml / s, and a suction power compensation coefficient K = 1.2, which means the suction pump power is increased by 20% to ensure that a large amount of flushing fluid and secretions can be suctioned out in time.

[0048] In this embodiment, preferably, the main control module 24 further includes a pump control unit, which controls the saline extrusion electric push rod 19 and the negative pressure suction pump 21 respectively. The negative pressure suction pump 21 adopts negative pressure closed-loop control, adjusting the suction power in real time according to the flushing flow rate to ensure that the flow ratio is maintained at 1:1.05±0.03, preventing liquid residue. Through the set pump control unit, precise control of the saline extrusion electric push rod 19 and the negative pressure suction pump 21 is achieved. Controlling the ejection speed and ejection distance of the saline extrusion electric push rod 19 can control the squeezing force and squeezing speed on the saline bag, thereby controlling the flow rate and impact force of the extruded flushing water, ensuring the stability and accuracy of the flushing flow rate, ensuring the flushing effect, and avoiding discomfort to the patient caused by excessive flow. The negative pressure suction pump 21 adopts negative pressure closed-loop control, automatically adjusting the suction power according to the real-time changes in the flushing flow rate, so that the flushing flow rate and suction flow rate maintain a constant ratio relationship, i.e., 1:1.05±0.03. This design effectively prevents liquid residue in the mouth, further enhancing the safety and comfort of oral care.

[0049] The brine connector 18 and the output of the negative pressure suction pump 21 are respectively equipped with a flushing valve and a suction valve. The flushing valve and the suction valve are synchronized by hardware PWM with a phase difference of <5ms.

[0050] Flow balance equation:

[0051]

[0052] When V accum When the volume is >0.5ml, Q will automatically increase. out The gain coefficient is 0.1, where Q in Input flow rate Q for brine connector 18 out To attract the pump's output flow, V accum This represents the volume of fluid accumulated in the oral cavity. This flow balance equation ensures the timely drainage of rinsing fluid and secretions, preventing the risks associated with fluid accumulation. Hardware PWM synchronous control of the rinsing and suction valves guarantees coordinated rinsing and suction actions.

[0053] In this embodiment, preferably, a digital display screen 6 is fixedly connected to the outer side of the center of the elastic expansion frame 2, and a catheter fixing clip 7 is fixedly connected to the inner side of the center of the elastic expansion frame 2. A fixing seat 8 is fixedly connected to the upper end of the main unit 1, and the fixing seat 8 matches the oral retractor with image acquisition. The digital display screen 6 can display the oral cavity nursing parameters in real time, allowing nursing staff to intuitively understand the patient's oral condition and make adjustments as needed. The catheter fixing clip 7 is used to firmly fix the coaxial double-lumen catheter, preventing it from shifting or falling off during nursing, and ensuring the continuity and stability of irrigation and suction. The design of the fixing seat 8 allows the oral retractor with image acquisition to be easily installed on the main unit 1, which not only facilitates operation but also improves the overall stability and reliability of the equipment.

[0054] In this embodiment, preferably, the coaxial dual-lumen catheter irrigation module further includes an irrigation head 11. Multiple irrigation nozzles are evenly distributed at the end of the irrigation head 11 away from the outer irrigation tube 10, and these nozzles communicate with the area between the negative pressure suction inner tube 9 and the outer irrigation tube 10 through channels in the sidewall of the irrigation head 11. A pressure sensor-equipped suction seat 14 is embedded in the center of the irrigation head 11, and a suction nozzle is provided on the sidewall of the pressure sensor-equipped suction seat 14. The pressure sensor-equipped suction seat 14 communicates with the inner cavity of the negative pressure suction inner tube 9, and the suction nozzle on the sidewall of the pressure sensor-equipped suction seat 14 penetrates the irrigation head 11. Through the irrigation head 11, the irrigation fluid can be evenly sprayed into the patient's oral cavity, improving the irrigation effect. The design of multiple irrigation nozzles allows the irrigation fluid to cover a wider area, ensuring that every corner of the oral cavity is thoroughly cleaned. Meanwhile, the rinsing nozzle connects to the area between the negative pressure suction inner tube 9 and the rinsing outer tube 10 through a channel in the side wall of the rinsing head 11. This design not only ensures smooth flow of the rinsing fluid but also allows waste fluid generated during rinsing to be promptly removed, preventing accumulation in the oral cavity. The suction seat 14 with a pressure sensor monitors pressure changes during suction in real time, ensuring stable and reliable operation of the suction pump. When the suction pressure exceeds a preset value, the system automatically adjusts the power of the suction pump to prevent discomfort to the patient due to excessive pressure. The suction nozzle penetrates the rinsing head 11, allowing waste fluid to be directly drawn into the negative pressure suction inner tube 9, further improving waste fluid collection efficiency.

Through the insertion design of the connecting mushroom heads 12 and the fixing holes 13, the connection between the elastic support frame 2 and the side silicone bracket 3 is more firm and reliable. This design not only facilitates installation and disassembly, allowing the side silicone bracket 3 to use disposable replacement materials, reducing the risk of cross-infection, but also enables rapid assembly through simple insertion operations, improving the ease of use and flexibility of the device. In addition, a sealing gasket is provided between the connecting mushroom heads 12 and the fixing holes 13 to ensure the seal during oral care, preventing leakage of rinsing fluid and dirt, further improving the quality and safety of care.

[0056] In this embodiment, preferably, an operation panel 25 is fixedly installed on the top of the main unit 1. The operation panel 25 is equipped with a touch screen display 26 and multiple operation buttons 27.

The design of the operation panel 25 allows caregivers to easily control the entire oral care process. The touch screen display 26 provides an intuitive user interface, allowing caregivers to adjust care parameters such as irrigation flow rate, suction power, and care mode using virtual buttons or sliders on the touch screen display 26. Simultaneously, the touch screen display 26 can also display images and care parameters inside the oral cavity in real time, helping caregivers monitor the care process and ensure the accuracy and safety of the operation. The multiple operation buttons 27 provide another control method, allowing caregivers to quickly perform specific operations by pressing the corresponding buttons, such as starting or stopping the irrigation and suction process, switching care modes, etc. This dual control design not only improves the flexibility and ease of use of the equipment but also allows caregivers to choose the most suitable operation method according to their habits and needs. Connecting to mains power via power cord 15 ensures the continuous and stable operation of the equipment, providing reliable power support for the oral care process.
