[0001] The present invention relates to the field of devices for inputting media into or onto the human body, and in particular to a high-flow respiratory humidification treatment device. Background Art

[0002] In the process of fighting the new crown epidemic, experts have discovered through exploration and clinical research that high-flow oxygen therapy has a good response for new crown patients. In the early and middle stages of the disease, the use of high-flow oxygen therapy has a significant effect on improving the patient's blood oxygen saturation. Since then, high-flow respiratory humidification therapy devices have been widely used in the treatment of new crown.

[0003] The basic working principle of high-flow oxygen therapy is to flush the patient's nasal cavity with a high-oxygen concentration and high-flow air-oxygen mixture. To improve patient comfort, high-flow ventilators are generally equipped with high-power humidification devices. To increase humidification efficiency, the heating plate at the bottom of the water tank generally provides a very high temperature, ranging from 80°C to 120°C. If the water tank runs low during operation, medical staff need to remove the water tank from the machine and refill it. During the process of removing and installing the water tank, medical staff may touch the high-temperature heating plate or the hot water tank bottom, posing a potential threat to their health.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0034] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0035] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0036] Please refer to Figures 1-11 This embodiment provides a high-flow respiratory humidification therapy device, including a device body 1, a heating component, a supply component, an anti-scalding component, and a control component 6. The device body 1 is provided with a mounting slot 101; the control component 6 is connected to the device body 1; the heating component includes a heater 2, which is arranged in the mounting slot 101; the supply component includes a liquid storage box 3, which is arranged on the top of the heater 2; the anti-scalding component includes a protective cover 4 and an anti-scalding cover 5, the protective cover 4 is connected to the periphery of the heater 2, the anti-scalding cover 5 is connected to the bottom of the side wall of the liquid storage box 3, the surfaces of the protective cover 4 and the anti-scalding cover 5 are both provided with a temperature-changing coating 7, the bottom of the anti-scalding cover 5 extends to the bottom of the heater 2, and the lower surface of the anti-scalding cover 5 is connected to a reset elastic member 501 and a baffle 502, an optical coupler switch 102 is provided in the mounting slot 101, the reset elastic member 501 controls the position of the baffle 502, and the baffle 502 controls the start and stop of the optical coupler switch 102.

[0037] It is worth noting that in this embodiment, all components are connected through the device body 1. The supply assembly enables the placement of liquid and the delivery of the air-oxygen mixture to the patient. The heating assembly heats the liquid placed in the supply assembly. The anti-scalding assembly protects the heating assembly and the supply assembly, preventing medical personnel from being burned when adding water to the high-flow respiratory humidification therapy device. The operation of each component is controlled by the control assembly 6. Specifically, within the mounting slot 101 defined in the device body 1, the heater 2 and the liquid reservoir 3 are sequentially disposed from bottom to top. The anti-scalding assembly includes a protective shield 4 and an anti-scalding cover 5. The anti-scalding cover 5 is disposed outside the mounting slot 101 and shields the lower portion of the liquid reservoir 3 and the entire side of the heater 2. Specifically, a reset spring 501 and a baffle 502 are connected to the lower surface of the anti-scalding cover 5. An optical coupler switch 102 is disposed within the mounting slot 101. The telescopic movement of the reset spring 501 causes the baffle 502 to change the distance relative to the bottom of the mounting slot 101. The first working mode is that the reset elastic member 501 is in a shortened state and the blocking piece 502 is away from the optical coupler switch 102. At this time, the blocking piece 502 does not block the optical coupler switch 102, and the device is in a normal working state; the second working mode is that when the medical staff is or is about to replace the liquid storage box 3, the medical staff needs to first apply a downward force to the anti-scalding cover 5 to remove it when removing the liquid storage box 3. The reset elastic member 501 extends and drives the blocking piece 502 to move downward so that it blocks the optical coupler switch 102. The optical coupler switch 102 recognizes the light signal and determines that the operator has the intention to take the water box, and then sends a signal to the control component 6. After receiving the signal, the control component 6 makes a corresponding warning, such as flashing a light or making a sound, to remind the operator of the high temperature danger and not to operate; the third working mode is that when the medical staff accidentally touches the anti-scalding cover 5 and applies a downward force to it, the control component 6 is prompted to issue a warning. The three working modes solve the problem that medical staff are easily scalded and have safety hazards during operation in the prior art.

[0038] In some embodiments, the anti-scalding cover 5 is provided with an anti-scalding groove 503 that mates with the outer circumference of the liquid reservoir 3. The protective cover 4 includes a main plate 401 and a main ring 402. The main plate 401 lies perpendicular to the plane of the main ring 402, and the main ring 402 is coaxially positioned on the top of the heater 2. The anti-scalding groove 503 allows the anti-scalding cover 5 to fit tightly against the outer circumference of the liquid reservoir 3. The main plate 401 mates with a side wall of the mounting groove 101, and the main ring 402 is positioned over the heater 2. Specifically, the temperature-variable coating 7 provides a more intuitive view of the temperature changes of the heater 2 and the liquid reservoir 3. The control component 6 sets a temperature safety parameter, and a temperature-variable coating with a corresponding composition is selected based on this temperature safety parameter. For example, at room temperature or a safety temperature, the temperature-variable coating 7 appears blue. When the temperature of the high-heat component exceeds the safety value of 60°C, the temperature-variable coating 7 changes from blue to red, alerting the medical staff operating the device through this temperature change. Preferably, the temperature-variable coating 7 is applied to all outer surfaces of the anti-scalding cover 5 and all outer surfaces of the main ring 402. Figure 11 The shown 60°C is only an example.

[0039] In some embodiments, the heater 2 includes a heating base 201, a heating plate 202 connected to one side of the heating base 201, a temperature sensor 203, a temperature fuse 204, and a heating connecting plate. A main ring 402 is disposed over the heating base 201. The side of the heating base 201 facing away from the heating plate 202 is in contact with the bottom of the liquid storage box 3. The temperature sensor 203 and the temperature fuse 204 are both connected to the heating plate 202, and the heating connecting plate is connected between the heating plate 202 and the heating base 201. The heater 2 also includes a plurality of heating elastic members 205 connected to the heating base 201 and spaced around the heating plate 202. The heating elastic members 205 flexibly connect the heating base 201 to the mounting slot 101. The heating base 201 secures the heating plate 202, temperature sensor 203, temperature fuse 204, and heating connecting plate, while also achieving a smoother fit with the liquid storage box 3. Specifically, the heating plate 202 acts as a heating element to provide heat, the temperature sensor 203 is used to measure the temperature of the heating plate in real time and feed it back to the control component 6, and the temperature fuse 204 is used to prevent the temperature sensor 203 from failing and to prevent risks when the temperature is out of control. The heating connecting piece is not shown in the figure and is used to tightly connect the heating base 201 to the heating plate 202. Preferably, the heating plate is made of aluminum, the heating plate 202 is made of ceramic, and the heating connecting piece is an elastic piece.

[0040] In some embodiments, the control assembly 6 includes a control module, a touchscreen display 601, a button 602, a light ring 603, an on / off switch 604, and a speaker connected to the control module. The on / off switch 604 controls the entire device's operation; the button 602 adjusts the device's parameters; the touchscreen display 601 displays various operating parameters, including but not limited to the temperature of the heating base 201 and the liquid storage box 3, enhancing the operator's awareness of and attention to burn hazards. The light ring 603 is coaxially arranged with the on / off switch 604 and emits different colors of light to warn the operator. In noisy environments, the speaker provides a dual warning of high-temperature and operational hazards. Specifically, the touchscreen display 601 can also be used to adjust and control various parameters. When the control module recognizes that the operator intends to remove the water box when the temperature is high, an alarm sounds, and the touchscreen display 601 displays messages such as "Temperature Too High" and "Do Not Touch Metal Parts to Avoid Burns."

[0041] In some embodiments, a top box 301, a bottom cover 302, a working tube 303, and a telescopic tube 304 are provided. The top box 301 and the bottom cover 302 are removed to clean or repair the interior thereof. The working tube 303 is used to import or export gas from the liquid storage box 3. The telescopic tube 304 can be extended or shortened according to different usage environments, thereby improving the environment and situation in which the entire device can be applied. In detail, there are two working tubes 303, one working tube 303 is used to input external dry air, and the other working tube 303 is used to output humidified humid air. The top box 301 is preferably made of a transparent material. Preferably, a liquid level line is provided on the top box 301 for displaying the water level therein. Preferably, a sealing sleeve is provided on the outside where the top box 301 is connected to the bottom cover 302 for preventing water leakage. It should be noted that the structure for humidifying air and mixing air and oxygen is prior art and will not be described in detail here.

[0042] In some embodiments, the outer circle of the bottom cover 302 is connected to a mounting ring 305 , the diameter of the top box 301 is smaller than the diameter of the bottom cover 302 , and a reinforcement groove 103 for inserting the mounting ring 305 is opened in the mounting groove 101 . When in use, first install the heater 2 in the installation groove 101, then connect the protective cover 4 with the installation groove 101, then push the liquid storage box 3 into the installation groove 101 from the outside of the installation groove 101 in parallel, specifically, the installation ring 305 is inserted parallel to the reinforcement groove 103, and then connect the anti-scalding cover 5 with the installation groove 101, and the outer circle of the installation ring 305 abuts against the anti-scalding groove 503. When it is necessary to move the liquid storage box 3, it is necessary to move the anti-scalding cover 5 first to achieve the removal of the liquid storage box 3. At this time, the position of the baffle 502 will be changed, and the optical coupler switch 102 will send a signal to the control module. The control module determines whether it is an over-temperature operation based on the temperature parameters transmitted by the temperature sensor 203. If the operator has over-temperature operation, the device will sound an alarm, the light ring 603 will light up or flash, and a warning message will be displayed on the touch display screen 601 to remind the operator again that there is a risk of scalding, and remind the operator to operate with caution to improve safety.

[0043] In some embodiments, the top box 301 is made of plastic, and the mounting ring 305 and bottom cover 302 are made of aluminum. The mounting ring 305 primarily conducts heat from the heater 2 into the bottom cover 302, transferring the high temperature of the heating plate 202 to the interior of the bottom cover 302, thereby increasing the water temperature and accelerating water evaporation, thereby increasing the humidity of the output gas.

[0044] In some embodiments, the optocoupler switch 102, the heater 202, the temperature sensor 203, the temperature fuse 204, and the resilient reset member 501 are all connected to a control module through signal connections. The control module controls the various operating parameters and operating states of the optocoupler switch 102, the heater 202, the temperature sensor 203, the temperature fuse 204, and the resilient reset member 501.

[0045] Preferably, the anti-scalding cover 5 includes an anti-scalding main plate, anti-scalding side plates, and an anti-scalding auxiliary plate. The anti-scalding main plate defines an anti-scalding groove 503. Two anti-scalding side plates are connected to either side of the anti-scalding main plate. The anti-scalding auxiliary plate is connected to the anti-scalding main plate and is located between the two anti-scalding side plates. The anti-scalding side plates and the anti-scalding auxiliary plate are both arranged perpendicular to the anti-scalding main plate. When in use, the anti-scalding auxiliary plate is located on the side away from the heater 2 and outside the mounting groove 101.

[0046] In some embodiments, the temperature-variable coating 7 is formed by injection molding or spraying to cover the entire anti-scalding cover 5 and the main ring 402 .

[0047] In some embodiments, a temperature indicator light or a micro display screen is provided on the top box 301 or the bottom cover 302 to display the real-time temperature through lights or numerical values.

[0048] In some embodiments, the alarm is performed in the form of voice broadcast.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
