Description

Technical Field

[0001] This invention belongs to the field of ventilator technology, and more specifically, relates to a tubeless integrated hollow cup brushless axial flow full-face ventilator. Background Technology

[0002] The ventilators commonly used by patients with COPD, obstructive sleep apnea, and special purpose ventilators consist of a gas (or oxygen-containing air) generating device and controller, and a breathing tube. Therefore, patients must use them in their hospital beds or at home, and are constrained and restricted by the breathing tube, which causes many inconveniences during treatment. In addition, the long breathing tube can also affect the breathing effect and cause dead space in the respiratory tract.

[0003] However, this traditional ventilator design with tubing causes numerous inconveniences for patients, severely impacting treatment adherence and quality of life. From a usage perspective, patients must be confined to a specific area in their hospital bed or home, unable to move freely. Clinically, patients experiencing acute exacerbations of COPD already suffer from breathing difficulties and limited mobility; the hindrance of the breathing tube further hinders their ability to turn over, sit up, or even perform simple bedside activities. For patients with obstructive sleep apnea, the tube is easily twisted and pulled during sleep due to turning over, affecting sleep comfort and potentially causing it to dislodge and interrupt treatment. For special populations requiring long-term home use, the presence of the tube prevents them from getting up, moving around, eating, or performing daily chores, leading to a prolonged state of "fixed-area confinement," which can easily cause anxiety, depression, and other negative emotions, thus reducing their motivation for treatment.

[0004] Therefore, there is an urgent need to design a tubeless ventilator to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a tubeless integrated hollow cup brushless axial flow full-face mask ventilator to solve the technical problems of traditional tubed ventilators in the prior art, such as restricting patient movement, creating dead space in the respiratory system, being prone to infection, and being cumbersome to maintain, resulting in low patient compliance.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a tubeless integrated hollow cup brushless axial flow full-face mask ventilator, comprising: The mask body has headbands on both sides for threading straps to secure it to the patient's face; A disposable latex face mask is located on the side of the mask body facing the face, so as to come into contact with the patient's face during wearing; An air supply housing is located on the side of the mask body away from the face; An air supply assembly, installed inside the air supply housing, is used to deliver air into the patient's face; The gas supply assembly includes: A hollow cup brushless axial flow fan is installed inside the air supply housing to draw in air and deliver it to the patient's face; The control module is electrically connected to the hollow cup brushless axial flow fan via a cable; The power supply module is electrically connected to the control module and the hollow cup brushless axial flow fan to provide power to the control module and the hollow cup brushless axial flow fan.

[0007] In one possible implementation, in conjunction with the above technical solutions, the ventilator further includes a respiratory control box, in which both the control module and the power module are installed.

[0008] In one possible implementation, based on the above technical solutions, the mask body has an exhalation hole for expelling the patient's exhaled gas, and a carbon dioxide sensor is installed on one side of the exhalation hole. The carbon dioxide sensor is electrically connected to the control module and the power module to detect the carbon dioxide concentration in the exhaled gas in real time and promptly detect carbon dioxide retention problems.

[0009] In one possible implementation, based on the above technical solutions, a respiratory pressure sensor is provided inside the disposable latex mask. The pressure sensor and the carbon dioxide sensor are electrically connected to the control module and the power module to monitor the pressure changes inside the mask during the patient's breathing process.

[0010] In one possible implementation, based on the above technical solutions, the gas supply housing includes a first housing and a second housing. The upper and lower ends of the second housing are provided with buckles, and the upper and lower walls of the first housing are provided with slots. The buckles are engaged in the slots, thereby fixing the second housing to one side of the first housing. Furthermore, a sealing rubber ring is provided on the side of the second housing facing the first housing to ensure the airtightness of the gas supply housing.

[0011] In one possible implementation, based on the above technical solutions, a first partition is formed inside the first housing, and the first partition and the first housing constitute a filtration and humidification chamber. The filtration and humidification chamber is provided with a disposable filtration and humidification layer for filtering and humidifying the air.

[0012] In one possible implementation, based on the above technical solutions, a second partition is formed on the first partition, and the first partition, the second partition, and the first shell constitute a heating cavity. A graphene heating layer is provided inside the heating cavity to heat the air.

[0013] In one possible implementation, based on the above technical solutions, an air inlet is provided on the side of the first housing away from the patient's face, and an air outlet is provided on the first partition, the second partition, and the first housing. An air delivery port is provided on the mask body and the disposable latex mask. The hollow cup brushless axial flow fan draws air through the air inlet and discharges it through the air outlet, and finally delivers it to the patient's face through the air delivery port.

[0014] In one possible implementation, based on the above technical solutions, the first housing is further provided with an installation cavity, and the hollow cup brushless axial flow fan is installed in the installation cavity. The hollow cup brushless axial flow fan uses mixed-flow fan blades inside. The mixed-flow fan blades are provided in one set or multiple sets of mixed-flow fan blades connected in series. The diameter of the air outlet of the hollow cup brushless axial flow fan is smaller than the diameter of the air inlet, so as to increase the fan air pressure to meet the tidal volume requirements of the small ventilator. An air pressure sensor is provided on one side of the air inlet of the hollow cup brushless axial flow fan to monitor the external air pressure entering the hollow cup brushless axial flow fan.

[0015] In one possible implementation, in conjunction with the above technical solutions, a display is also provided on one side of the first housing. The display is electrically connected to the control module and the power module. One side of the mask body is provided with an oxygen replenishment port for connecting to an oxygen supply tube to mix oxygen into the breathing gas. The other side is provided with a power control circuit port for plugging into the end of the cable.

[0016] The beneficial effects of the tubing-free integrated hollow cup brushless axial flow full-face mask ventilator provided by this invention are as follows: Compared with the prior art, the beneficial effects of this invention are: 1. Eliminating the constraints of tubing and improving freedom of movement: This invention abandons the external breathing tubing of traditional ventilators, integrating the air supply component into the air supply housing and combining it with the mask body as one piece. After wearing it, the patient can move freely without being fixed in a specific area, effectively solving the problem of traditional tubing ventilators restricting the patient's movement, and greatly improving the patient's treatment compliance and quality of life; 2. Optimizing respiratory effect and eliminating dead space: The tubing-free integrated design avoids long... The dead space problem caused by the tubing is addressed by using a hollow cup brushless axial flow fan with a smaller outlet diameter than the inlet diameter. This, combined with the mixed-flow fan blade design, effectively increases air pressure, meeting the tidal volume requirements of small ventilators, ensuring the stability and effectiveness of air supply, and improving respiratory support. 3. Multiple air treatments enhance respiratory comfort: The air supply housing is equipped with a filtration and humidification chamber and a heating chamber. The disposable filtration and humidification layer filters and humidifies the inhaled air, while the graphene heating layer heats the air, ensuring that the air delivered to the patient's face reaches a suitable temperature and humidity, reducing irritation to the respiratory tract and improving patient comfort during wear and breathing.

[0020] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention.

However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0022] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0023] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features.

In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0026] The present invention will now describe a tubeless integrated hollow cup brushless axial flow full-face ventilator.

[0027] like Figures 1 to 5 As shown, this invention provides a tubeless integrated hollow cup brushless axial flow full-face ventilator, including a mask body 100, a disposable latex mask 200, an air supply shell 300, and an air supply assembly 400. The mask body 100 serves as the main support structure, and elastic straps can be threaded through the headbands 110 on both sides to fix the entire ventilator to the patient's face. The disposable latex mask 200 fits against the side of the mask body 100 facing the patient's face. It is made of flexible latex material, which can fit closely to the patient's face, ensuring a seal while improving wearing comfort. It is also disposable, effectively avoiding cross-infection.

[0028] like Figure 1As shown, the air supply housing 300 is fixed to the side of the mask body 100 away from the patient's face. Its interior is hollow and used to install the air supply assembly 400 and various air handling components. The air supply assembly 400 is the core air supply structure of the ventilator, including a hollow cup brushless axial flow fan 410, a control module, and a power module. The hollow cup brushless axial flow fan 410 is installed in the mounting cavity 316 of the air supply housing 300. The control module and power module are integrated in the respiratory control box 500, which can be placed on the side of the air supply housing 300 or held by hand. The power module is an embedded rechargeable medical lithium battery that can provide power to the electrical components of the entire device. The control module is electrically connected to the hollow cup brushless axial flow fan 410 through the cable 150 and can adjust the fan speed to control the air volume and air pressure of the air supply to meet the respiratory needs of different patients.

[0029] Compared with existing technologies, the tubeless integrated hollow cup brushless axial flow full-face mask ventilator provided by this invention eliminates the constraints of tubing, improves freedom of movement, and abandons the external breathing tubing of traditional ventilators. The air supply component 400 is integrated into the air supply housing 300 and combined with the mask body 100 as one unit. After wearing it, the patient can move freely without being fixed in a specific area, effectively solving the problem of traditional tubing ventilators restricting the patient's movement, and greatly improving the patient's treatment compliance and quality of life.

[0030] like Figure 2 As shown, in this embodiment, the mask body 100 has several exhalation holes 120 distributed on it to expel the patient's exhaled air and prevent the exhaled air from accumulating inside the mask. A carbon dioxide sensor 600 is installed on one side of the exhalation hole 120, and a respiratory pressure sensor 210 is attached to the inner wall of the disposable latex mask 200. Both the carbon dioxide sensor 600 and the respiratory pressure sensor 210 are electrically connected to the control module and the power module. The carbon dioxide sensor 600 can detect the carbon dioxide concentration in the exhaled air in real time and transmit the detection data to the control module. If the concentration exceeds the standard, the control module can issue an early warning through the display 900 to promptly detect the patient's carbon dioxide retention problem. The respiratory pressure sensor 210 can monitor the pressure changes inside the mask in real time to avoid abnormal pressure inside the mask due to the mask being too tight or the fan pressure being too high, thus ensuring the patient's safety.

[0031] like Figures 3 to 5As shown, the gas supply housing 300 is composed of a first housing 310 and a second housing 320. For easy disassembly and maintenance, the upper and lower ends of the second housing 320 are integrally formed with elastic buckles 321. The upper and lower walls of the first housing 310 are respectively provided with slots 311. The buckles 321 can be elastically engaged in the slots 311 to achieve quick fixation of the first housing 310 and the second housing 320. A sealing rubber ring 322 is glued to the side of the second housing 320 facing the first housing 310. When the first housing 310 and the second housing 320 are engaged, the sealing rubber ring 322 can fill the gap between them to ensure the airtightness of the gas supply housing 300 and avoid gas leakage during the gas supply process.

[0032] like Figure 4 As shown, the first housing 310 has a first partition 312 and a second partition 313 integrally formed inside. The first partition 312 and the inner wall of the first housing 310 enclose a filtration and humidification chamber 314. A disposable filtration and humidification layer 700 is placed inside the filtration and humidification chamber 314. This filtration and humidification layer 700 is a disposable water-containing air purification filter membrane that can filter the air drawn in by the hollow cup brushless axial flow fan 410, removing dust, particulate matter, odors and other impurities from the air, while humidifying the dry air to prevent dry air from irritating the patient's respiratory system. The airway; the first partition 312, the second partition 313 and the inner wall of the first housing 310 enclose a heating cavity 315, in which a graphene heating layer 800 is placed. The graphene heating layer 800 is electrically connected to the control module and the power module, and can convert electrical energy into heat energy. The air is first heated by the graphene heating layer 800, and then filtered and humidified by the disposable filter and humidification layer 700. The control module can adjust the heating temperature to keep the air delivered to the patient's face at a suitable temperature of 22-30°C, thereby improving breathing comfort.

[0033] like Figure 4 As shown, an air inlet 317 is provided on the side of the first housing 310 away from the patient's face. A dust filter can be installed at the air inlet 317 to further filter large particulate impurities in the air. Air outlets are provided on the first partition 312, the second partition 313, and the side wall of the first housing 313. Air supply ports are provided in the middle of the mask body 100 and the disposable latex mask 200. When the hollow cup brushless axial flow fan 410 is working, it draws in outside air through the air inlet 317. The air passes through the heating chamber 315 and the filtration and humidification chamber 314 in sequence for heating, filtration, and humidification treatment, and is then discharged through the air outlet. Finally, it is delivered to the patient's face through the air supply port to complete the air supply process.

[0034] To meet the tidal volume requirements of small ventilators, the hollow cup brushless axial flow fan 410 uses mixed-flow fan blades. A single set of mixed-flow fan blades can be installed, or multiple sets can be connected in series, to improve the fan's extraction efficiency. Simultaneously, the outlet diameter of the hollow cup brushless axial flow fan 410 is designed to be smaller than the inlet diameter. Utilizing fluid dynamics principles, this effectively increases the outlet air pressure during fan rotation, ensuring the strength and stability of the air supply. This design is suitable for patients with various conditions such as COPD and obstructive sleep apnea. Furthermore, an air pressure sensor 420 is installed on the inlet side of the hollow cup brushless axial flow fan 410 to monitor the external air pressure entering the fan.

[0035] like Figure 1 As shown, a display 900 is embedded in the outer wall of the first housing 310. The display 900 uses a small LCD screen and is electrically connected to the control module and power module. It can display data such as carbon dioxide concentration, mask pressure, fan speed, heating temperature, and remaining power in real time, making it convenient for patients and medical staff to view the working status of the equipment and the patient's vital signs. If abnormal data occurs, the display 900 can simultaneously display an early warning prompt, improving the convenience and safety of equipment use. An oxygen supplement is provided on one side of the mask body 100. The oxygen jack 130 is equipped with a one-way valve. When a patient needs oxygen, the oxygen source can be connected to the oxygen jack 130 to mix oxygen into the breathing gas, precisely adjusting the oxygen concentration to meet the oxygen needs of different patients such as COPD and high-altitude hypoxia. On the other side of the mask body 100, there is a power control circuit jack 140. The circuit jack 140 is electrically connected to the graphene heating layer 800, the hollow cup brushless axial flow fan 410, and various sensors to insert the cable 150, thereby electrically connecting to the control module and the power module.

[0036] When using the ventilator of this invention, firstly, the disposable latex mask 200 is fitted to the inside of the mask body 100, the elastic strap is threaded through the headband 110, the mask is worn on the patient's face, and the tightness of the strap is adjusted to ensure a tight fit between the disposable latex mask 200 and the patient's face; then, the device power is turned on, and the control module starts the hollow cup brushless axial flow fan 410. The fan draws in outside air through the air inlet 317, and the air passes through the graphene heating layer 800 and the filter and humidification layer 700 in sequence, undergoing heating, filtration, and humidification, before being delivered to the patient's face. The patient's exhaled air is discharged through the exhalation port 120. The carbon dioxide sensor 600, respiratory pressure sensor 210, and air pressure sensor 420 detect relevant data in real time and display it on the display 900. Medical staff or patients can adjust parameters such as fan speed and heating temperature according to actual needs through the adjustment buttons on the control module or by directly operating the display 900. If the carbon dioxide concentration exceeds the standard or the mask pressure is abnormal, the device will issue an early warning in time. In addition, the control module is also equipped with a wireless module, such as a Bluetooth module, so patients can also use mobile devices to connect to Bluetooth to set and adjust parameters such as fan speed and heating temperature.

[0037] After use, turn off the power to the device, remove and discard the disposable latex mask 200. If the filter humidification layer 700 has been used for too long, open the second housing 320 of the air supply housing 300 and replace it with a new disposable filter humidification layer 700. Then clean the device and put it away. When the power module is low on power, it can be charged by connecting to an external power source via a charging cable for reuse.
