Headgear for a ventilator and a ventilator

Abstract

The application relates to a headband for a breathing machine and the breathing machine. The headband comprises a main band, two first connecting bands and two second connecting bands, and can be adjusted according to the face shape and head contour of a user, and is suitable for different users. Since a heating module is arranged in the headband, the condensation phenomenon of humid air in the mask can be reduced or prevented by heating the surrounding area of the mask, sufficient humidity can be ensured to be delivered to the respiratory tract, and nasal cavity dryness and discomfort can be reduced. Especially in cold environments, heating the headband can provide a warm touch for the user, reduce the discomfort caused by contact with cold materials, and improve the user experience. Moreover, flexible headbands may become hard at low temperatures, thereby affecting their fit with the face. Heating the headbands by the heating module can make them softer and more elastic, thereby better fitting the face contour, improving the sealing performance, reducing the possibility of air leakage, and ensuring the use effect of the breathing machine.

[0001] This application relates to the field of ventilator technology, and in particular to headbands for ventilators and ventilators. Background Technology

[0002] A ventilator is a device used to assist or replace a patient's spontaneous breathing. It is widely used in various settings such as intensive care, emergency care, and home care.

[0003] In ventilator systems, headbands play a crucial role, especially for patients requiring non-invasive ventilation with a face mask. The primary function of the headband is to ensure the mask is securely fastened to the patient's face, thereby guaranteeing effective airflow and therapeutic efficacy.

[0004] Among related technologies, the user experience of headbands is poor. Utility Model Content

[0005] Therefore, it is necessary to provide a headband for ventilators that addresses the problems existing in current ventilator headbands.

[0006] A headband for a ventilator, the headband for a ventilator comprising:

[0007] Main belt;

[0008] Two first connecting straps are arranged along a first direction; the two first connecting straps are connected to one end of the main strap along a second direction; a first connecting portion is provided at the end of the two first connecting straps away from the main strap, the first connecting straps are connected to the face mask through the first connecting portion, and the face mask can be connected to different positions of the first connecting straps;

[0009] Two second connecting straps are arranged along the first direction; the two second connecting straps are connected to the other end of the main strap along the second direction; a second connecting portion is provided at the end of the two second connecting straps away from the main strap, the second connecting straps are connected to the face mask through the second connecting portion, and the face mask can be connected to different positions of the second connecting straps;

[0010] At least one of the main belt, the first connecting belt, and the second connecting belt is provided with a heating module.

[0011] In one embodiment, the main belt, the first connecting belt, and the second connecting belt are all provided with the heating module.

[0012] In one embodiment, the headband further includes a temperature measurement module disposed in at least one of the main strap, the first connecting strap, and the second connecting strap, and the temperature measurement module is communicatively connected to the heating module.

[0013] In one embodiment, the main belt and the two first connecting belts form a clearance groove.

[0014] In one embodiment, the first connecting belt includes a first branch belt and a second branch belt connected to the first branch belt, the first branch belt and the main belt forming the clearance groove; the second branch belt intersects the extension direction of the first branch belt.

[0015] In one embodiment, the first connecting portion includes a first sub-Hook and loop fastener and a first female hook and loop fastener, the first sub-Hook and loop fastener passing through the face mask and connected to the first female hook and loop fastener; and / or,

[0016] The second connecting part includes a second sub-hook and a second female hook and loop fastener, the second sub-hook and loop fastener passing through the face mask and connected to the second female hook and loop fastener.

[0017] In one embodiment, a first scale mark is provided on the first connecting strip near the first connecting portion; and / or,

[0018] The second connecting strip has a second scale mark located near the second connecting part.

[0019] In one embodiment, at least one of the main strap, the first connecting strap, and the second connecting strap is provided with ventilation holes; and / or,

[0020] At least one of the main strap, the first connecting strap, and the second connecting strap is provided with an anti-allergy coating.

[0021] In one embodiment, the headband further includes a pressure measurement module disposed on at least one of the main strap, the first connecting strap, and the second connecting strap.

[0022] A ventilator, including a headband for use as described above.

[0023] The headband used in the ventilator described above, via two first connecting straps and two second connecting straps, allows the headband to connect to the mask from multiple directions and positions, ensuring reliable wear on the user's head. Because the mask can be connected to different positions on the first and second connecting straps, it can be adjusted according to the user's face shape and head contour, ensuring even pressure distribution to accommodate different users and provide a personalized comfort experience. Simultaneously, the headband's fit helps ensure a tight seal between the mask and the patient's face, preventing air leakage from gaps and ensuring effective airflow into the respiratory tract. This avoids pressure drops and reduced therapeutic effects caused by leakage, maintaining a constant inflow pressure. Furthermore, for ventilators equipped with humidifiers, humidified air enters the mask through a duct. If the ambient temperature is low, condensation may form inside the mask, affecting patient comfort. The headband incorporates a heating module that heats the area around the mask, reducing or preventing condensation and ensuring sufficient humidity is delivered to the respiratory tract, reducing nasal dryness and discomfort. Especially in cold environments, heating the headband can provide users with a warm touch, reducing discomfort caused by contact with cold materials and improving the user experience. Furthermore, since headbands are generally made of flexible materials such as silicone, they may harden at low temperatures, affecting their fit to the face. Heating the headband with a heating module can make it softer and more elastic, thus better conforming to facial contours, improving sealing performance, reducing the possibility of air leakage, and ensuring the effectiveness of the ventilator.

[0033] A ventilator is a device used to assist or replace a patient's spontaneous breathing, widely used in intensive care, emergency care, and home care. In a ventilator system, the headband plays a crucial role, especially for patients requiring non-invasive ventilation with a face mask. The main function of the headband is to ensure the mask is securely fixed to the patient's face, thereby guaranteeing effective airflow and therapeutic efficacy. However, some headbands in this technology offer a poor user experience. For example, they can feel cold when worn, and the headband portion is primarily made of traditional fabric. These fabric headbands present several problems during use, such as difficulty in cleaning and disinfection, easy absorption of dust and bacteria, and slow drying after washing, thus impacting the user experience.

[0034] Based on this, one embodiment of this application provides a headband for a ventilator, which can improve the user experience. The headband for a ventilator provided in one embodiment of this application will be described in detail below with reference to the accompanying drawings.

[0035] See Figure 1 or Figure 2As shown in the figure, an embodiment of this application provides a headband for a ventilator. The headband includes a main strap 100, two first connecting straps 200, and two second connecting straps 300. The two first connecting straps 200 are arranged along a first direction. The two first connecting straps 200 are connected to one end of the main strap 100 along a second direction. A first connecting portion 230 is provided at the end of each of the two first connecting straps 200 away from the main strap 100. The first connecting straps 200 are connected to a face mask (not shown) through the first connecting portion 230, and the face mask can be connected to the first connecting portion 300. Different positions of the connecting strap 200; two second connecting straps 300 arranged along a first direction; the two second connecting straps 300 connected to the other end of the main strap 100 along a second direction; a second connecting part 310 is provided at the end of the two second connecting straps 300 away from the main strap 100, the second connecting straps 300 are connected to the face mask through the second connecting part 310, and the face mask can be connected to different positions of the second connecting straps 300; wherein, at least one of the main strap 100, the first connecting strap 200 and the second connecting strap 300 is provided with a heating module 400.

[0036] The headband used in the ventilator described above, via two first connecting straps 200 and two second connecting straps 300, allows the headband to connect to the mask from multiple directions and positions, ensuring reliable wear on the user's head. Because the mask can be connected to different positions on the first connecting straps 200 and second connecting straps 300, it can be adjusted according to the user's face shape and head contour, ensuring even pressure distribution to accommodate different users and provide a personalized comfort experience. Simultaneously, the close fit between the headband and the user helps to ensure a tight fit of the mask to the patient's face, preventing air leakage from gaps between the mask and the face, ensuring effective airflow into the respiratory tract, avoiding pressure drops and reduced therapeutic effects due to leakage, and maintaining a constant inlet airflow pressure. Furthermore, for ventilators equipped with humidifiers, humidified air enters the mask through a duct; if the ambient temperature is low, condensation may occur inside the mask, affecting patient comfort. Because the headband is equipped with a heating module 400, which heats the area around the mask, it reduces or prevents condensation, ensuring sufficient humidity is delivered to the respiratory tract and reducing nasal dryness and discomfort. Especially in cold environments, heating the headband provides a warm touch, reducing discomfort caused by contact with cold materials and improving the user experience. Furthermore, since headbands are generally made of flexible materials such as silicone, they may harden at low temperatures, affecting their fit to the face. Heating the headband with the heating module 400 makes it softer and more elastic, better conforming to facial contours, improving sealing performance, reducing the possibility of air leakage, and ensuring the effectiveness of the ventilator.

[0037] In some embodiments, the headband is made of a soft rubber material such as silicone, which has good flexibility and a certain degree of deformation ability, making it more suitable for the user's head, without irritating the skin, and improving the user's comfort and experience during long-term wear. At the same time, this material makes the surface of the headband relatively smooth, making it less prone to dirt accumulation and very convenient to clean. Moreover, the soft rubber material has good high temperature resistance and chemical resistance, and can be quickly disinfected using various disinfection methods. For example, the headband can be boiled in hot water for disinfection and cleaning, which greatly improves the efficiency of cleaning and disinfection without loss of effectiveness. After washing, the soft rubber material does not absorb water and can be easily wiped dry quickly, which is more convenient than traditional cloth headbands and has the advantages of being easy to clean, easy to disinfect, and easy to replace.

[0038] In some embodiments, such as Figure 1 As shown, the main strap 100, the first connecting strap 200, and the second connecting strap 300 can be assembled from multiple parts. For example, the headband can be assembled using a composite injection molding method where soft rubber is used to encapsulate hard rubber. For instance, the main strap 100 can be made of hard rubber, while the first connecting strap 200 and the second connecting strap 300 can be made of soft rubber. The soft rubber can be a thermoplastic elastomer (TPE), silicone, or other soft, elastic materials with high temperature resistance and excellent chemical stability. These materials are characterized by being soft, wear-resistant, comfortable to the touch, and quick-drying. The hard rubber can be a high-hardness plastic material such as polypropylene (PP), polycarbonate (PC), or ABS. Because the main strap 100, the first connecting strap 200, and the second connecting strap 300 are assembled from multiple modular components, it is convenient for users to regularly clean each component, reducing the risk of bacterial growth. Simultaneously, when certain components are worn or damaged, only one component can be replaced without replacing the entire headband, reducing replacement costs.

[0039] In other embodiments, such as Figure 2 As shown, the main belt 100, the first connecting belt 200 and the second connecting belt 300 can also be integrally molded, for example, by injection molding of soft rubber, which makes processing more convenient.

[0040] like Figure 2 As shown, in some embodiments, the heating module 400 can be embedded in the headband using an injection molding process. The heating module 400 can be a heating element or a heating wire, etc. For example, in the embodiment shown in the figures, the heating module 400 is a heating wire. In some embodiments, the headband is provided with a power interface 340, and the heating module 400 is put into a heating state by connecting a power source. In other embodiments, the heating module 400 can also be powered by a built-in power supply.

[0041] See Figure 2As shown in the figure, in one embodiment, the main strap 100, the first connecting strap 200, and the second connecting strap 300 are all equipped with heating modules 400. For example, in the embodiment shown in the figure, the main strap 100, the first connecting strap 200, and the second connecting strap 300 are all equipped with heating modules 400, enabling them to cover a larger heating area, i.e., a larger heating surface, providing more uniform and widespread warm coverage, reducing local cold spots, and allowing the user to feel a comfortable temperature throughout the wearing process, further enhancing the user experience. At the same time, when the heating area is increased, more of the mask edge material will be heated and softened due to the effect of heat conduction. This helps the mask to better conform to the facial contours, adapting to the needs of different face shapes and sizes, and maintaining a good fit even on complex or irregular facial contours, thereby improving sealing performance and reducing air leakage. In addition, large-area heating can maintain the temperature of the environment around the mask at a relatively high level, thereby reducing or preventing the formation of condensation due to temperature differences after humidified air enters the mask.

[0042] See Figure 2 As shown, in one embodiment, the headband further includes a temperature measurement module 500, which is disposed on at least one of the main strap 100, the first connecting strap 200, and the second connecting strap 300. The temperature measurement module 500 is communicatively connected to the heating module 400. For example, in the embodiment shown in the figures, the temperature measurement module 500 is disposed on the second connecting strap 300. Of course, in other embodiments, the temperature measurement module 500 may also be disposed on the first connecting strap 200 or the main strap 100.

[0043] By incorporating a temperature measurement module 500, the headband temperature can be monitored in real time, allowing for precise temperature adjustment based on the user's actual needs. This helps ensure the user remains within a comfortable temperature range throughout use and prevents localized overheating caused by excessive heating, reducing the risk of skin burns or other discomfort. Simultaneously, it ensures sufficient warmth in cold environments, avoiding discomfort caused by contact with cold materials. When the headband is made of soft rubber, the rubber exhibits different hardness at different temperatures. Temperature detection helps maintain these materials in an ideal soft state for optimal facial fit and seal. In some embodiments, the temperature measurement module 500 can be a temperature sensor.

[0044] See Figure 1 or Figure 2As shown, in one embodiment, the main strap 100 and the two first connecting straps 200 form a relief groove 110. Since the main strap 100 is located behind the user's head when in use, the relief groove 110 can avoid the back of the user's head, reducing the discomfort caused by foreign objects when wearing it during sleep and improving the user experience.

[0045] See Figure 1 or Figure 2 As shown, in one embodiment, the first connecting strap 200 includes a first branch strap 210 and a second branch strap 220 connected to the first branch strap 210. The first branch strap 210 and the main strap 100 form a clearance groove 110; the extension direction of the second branch strap 220 intersects with that of the first branch strap 210. In the embodiment shown in the figures, the included angle between the first branch strap 210 and the second branch strap 220 is an obtuse angle. By having the first branch strap 210 and the second connecting strap 300 extend in different directions, the force distribution of the headband is more uniform, and it can be connected to the mask from multiple directions, thereby improving the wearing effect.

[0046] See Figure 1 or Figure 2 As shown, in one embodiment, the first connecting part 230 includes a first sub-hook and a first female hook and loop fastener. The face mask is provided with corresponding connecting interfaces, for example, four interfaces are provided at the four corners of the face mask. Two first connecting straps 200 and two second connecting straps 300 are respectively connected to the four interfaces one-to-one. Taking the first connecting strap 200 as an example, the first sub-hook and loop fastener of the first connecting strap 200 passes through the face mask interface and connects to the first female hook and loop fastener, thereby achieving the connection between the first connecting strap 200 and the face mask. Using hook and loop fasteners for fixation is more convenient and faster. By providing a first female hook and loop fastener with a certain coverage area, the first sub-hook and loop fastener can be pasted at different positions on the first female hook and loop fastener, thereby adjusting the connection position between the face mask and the first connecting strap 200, that is, adjusting the distance between the main strap 100 and the face mask, thus adapting to users with different head shapes.

[0047] See Figure 1 or Figure 2 As shown, in one embodiment, the second connecting part 310 includes a second sub-hook and a second female hook and loop fastener. The second sub-hook and loop fastener passes through the face mask and connects to the second female hook and loop fastener. Thus, the second sub-hook and loop fastener pass through the face mask interface and connect to the second female hook and loop fastener, thereby achieving the connection between the second connecting strap 300 and the face mask. By providing a second female hook and loop fastener with a certain coverage area, the second sub-hook and loop fastener can be attached to different positions on the second female hook and loop fastener, thereby adjusting the connection position between the face mask and the second connecting strap 300 to accommodate users with different head shapes.

[0048] See Figure 2As shown, in one embodiment, the first connecting strap 200 has a first scale mark near the first connecting portion 230. In some embodiments, the second connecting strap 300 has a second scale mark 320 near the second connecting portion 310. By setting scale marks, users can more easily find and remember the ideal adjustment position, enabling quick wearing without repeated adjustments to tightness, thus improving wearing efficiency.

[0049] See Figure 2 As shown, in one embodiment, at least one of the main strap 100, the first connecting strap 200, and the second connecting strap 300 is provided with ventilation holes 330. For example, in the embodiment shown in the figures, both the first connecting strap 200 and the second connecting strap 300 are provided with ventilation holes 330. By providing a multiple ventilation hole structure 330 on the headband, air circulation can be increased, which helps to reduce the stuffiness and discomfort of the user during long-term wear, and further improves the user's wearing comfort. In other embodiments, the first connecting strap 200 and the second connecting strap 300 may also be made of materials with good breathability and moisture-wicking properties.

[0050] See Figure 2 As shown, in one embodiment, at least one of the main strap 100, the first connecting strap 200, and the second connecting strap 300 is provided with an anti-allergy coating, thereby reducing irritation or allergic reactions caused by prolonged wear. For example, in some embodiments, the main strap 100, the first connecting strap 200, and the second connecting strap 300 are all coated with an anti-allergy coating. In other embodiments, the anti-allergy coating may be applied only to the first connecting strap 200 or the second connecting strap 300. In some embodiments, the anti-allergy coating may be a silicone coating, a plant oil-based coating, or a polyurethane (PU) coating, etc.

[0051] In one embodiment, the headband further includes a pressure measurement module (not shown), which is disposed in at least one of the main strap 100, the first connecting strap 200, and the second connecting strap 300. The pressure measurement module detects the pressure applied to the head by the headband, allowing for precise adjustments based on the user's specific needs. This helps ensure the mask is securely fixed to the face, avoiding discomfort caused by excessive pressure and reducing the risk of skin damage from excessive pressure, thus improving the user experience. In some embodiments, the pressure measurement module can be a pressure sensor.

[0052] Furthermore, one embodiment of this application also provides a ventilator (not shown) including a headband as described in any of the above embodiments. Because this ventilator includes the headband, it can be connected to the mask from multiple directions and positions, ensuring the reliability of the headband on the user's head. Since the mask can be connected to different positions on the first connecting strap 200 and the second connecting strap 300, it can be adjusted according to the user's face shape and head contour, ensuring that the headband can evenly distribute pressure to adapt to different users and provide a personalized comfort experience. Simultaneously, the fit between the headband and the user helps to ensure a tight fit of the mask to the patient's face, preventing air leakage from the gap between the mask and the face, ensuring that gas can effectively enter the respiratory tract, avoiding pressure drops and weakened treatment effects due to air leakage, and ensuring a constant pressure of the input airflow. At the same time, for ventilators equipped with humidifiers, humidified air enters the mask through a duct; if the ambient temperature is low, condensation may occur inside the mask, affecting the patient's comfort. Because the headband is equipped with a heating module 400, which heats the area around the mask, it reduces or prevents condensation, ensuring sufficient humidity is delivered to the respiratory tract and reducing nasal dryness and discomfort. Especially in cold environments, heating the headband provides a warm touch, reducing discomfort caused by contact with cold materials and improving the user experience. Furthermore, since headbands are generally made of flexible materials such as silicone, they may harden at low temperatures, affecting their fit to the face. Heating the headband with the heating module 400 makes it softer and more elastic, better conforming to facial contours, improving sealing performance, reducing the possibility of air leakage, and ensuring the effectiveness of the ventilator.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
