Description

Technical Field

[0001] This application relates to the field of ventilator technology, and in particular to a breathing hose, a breathing assembly, and a ventilator. Background Technology

[0002] A ventilator, also known as a ventilator or mechanical respirator, is a medical device that provides assistance or complete replacement for natural breathing when a patient is unable to maintain sufficient respiratory function on their own. It helps maintain proper gas exchange by delivering a predetermined pressure and volume of air or other oxygen-oxygen mixture to the patient's lungs, ensuring that the body's organs receive enough oxygen and expel carbon dioxide.

[0003] In related technical fields, a ventilator includes a main unit, a water tank, and a breathing hose connected to the water tank. A heat-conducting component is installed at the bottom of the water tank, and a heating element is installed on the main unit that is in contact with the heat-conducting component. The heat-conducting component is used to conduct heat from the heating element to the liquid in the water tank, humidifying and heating the liquid. When the ventilator is working, the fan in the main unit draws in air, and the airflow generated by the fan flows through the water tank and out through the breathing hose to the user's nasal cavity.

[0004] However, the existing breathing tubing has limited applications. It can only be used to connect the air outlet of the ventilator's water tank to the user's nasal cavity. If the user needs to use other respiratory medications during the use of the ventilator, such as nasal medications or traditional Chinese medicine fumigation packs, the breathing tubing and nasal mask / nose pillow need to be removed in order to use other medications. Utility Model Content

[0005] Therefore, it is necessary to provide a breathing hose, a breathing assembly, and a ventilator to address the issue of limited application scenarios for breathing hoses.

[0006] A breathing hose, the breathing hose comprising:

[0007] The pipeline body has a flow channel for gas flow;

[0008] Two tubing connectors are respectively located at both ends of the tubing body. One of the two tubing connectors is used to connect to the water tank of the ventilator, and the other is used to connect to the nasal mask or nasal pillow.

[0009] An installation component is used to carry the medicine package. The installation component is disposed in the flow channel and abuts against the pipe wall of the pipeline body to divide the flow channel into a first channel and a second channel. The installation component is provided with a first through hole connecting the first channel and the second channel.

[0010] In one embodiment, the mounting component includes an annular abutment plate and a plurality of support bars. The annular abutment plate abuts against the pipe wall, and the plurality of support bars are disposed within the inner ring of the annular abutment plate and connected to the annular abutment plate. A first through hole is formed between two adjacent support bars.

[0011] In one embodiment, a sealing cap is also included, which is fastened to one end of the pipeline body. The sealing cap and the mounting component form an installation space for accommodating the medicine pack, and the sealing cap is provided with a second through hole.

[0012] In one embodiment, the plugging cap is provided with a snap-fit ​​part, and the outer peripheral surface of the pipeline body is provided with a mating part, and the snap-fit ​​part is snapped into the mating part;

[0013] Multiple snap-fit ​​parts are arranged circumferentially around the sealing cap, and multiple mating parts are arranged circumferentially around the pipeline body, with each snap-fit ​​part and mating part corresponding to and engaging with the other.

[0014] In one embodiment, a first annular protrusion is provided on the outer peripheral surface of the pipeline body, and the first annular protrusion is located on the side of the mating part away from the sealing cap.

[0015] The pipe joint has a second annular protrusion on its inner circumferential surface. The pipe joint is sleeved on the pipe body, and the second annular protrusion overlaps with the first annular protrusion.

[0016] In one embodiment, a heating element disposed on the pipeline body is further included, the heating element being used to heat the gas in the flow channel.

[0017] In one embodiment, the heating element is a heating wire, which is embedded in the flow channel and integrally formed with the pipeline body.

[0018] In one embodiment, a temperature sensor and / or humidity sensor are also provided on the pipeline body.

[0019] This application also provides a breathing assembly, including a nasal interface and a breathing hose as described in any of the above claims, wherein one of the two tubing connectors is connected to the nasal interface, and the nasal interface is a nasal mask or a nasal pillow.

[0020] This application also provides a ventilator, including a main unit, a water tank, and the above-described breathing components, wherein the air outlet of the water tank is connected to another of the aforementioned tubing connectors.

[0021] The aforementioned breathing hose has connectors at both ends of its main body. One end of the hose connects to the air outlet of the water tank, and the other end connects to a nasal mask or nasal pillow. When using the ventilator, the airflow generated by the ventilator unit is humidified by the water tank and then flows through the hose's channels to the nasal mask / pillow, ultimately reaching the user's nasal cavity. A mounting component within the channels holds the medication pack. This component abuts against the hose wall, dividing the channels into a first and a second channel. A first through-hole in the mounting component connects the first and second channels, allowing for gas flow. The breathing tubing of this application has an installation component installed in the flow channel, which carries a medication pack. When gas flows through the flow channel, it can flow through the medication pack, and the gas after flowing through the medication pack can also flow into the nasal mask / nose pillow, and then into the user's nasal cavity. This allows other medications, such as rhinitis medication or traditional Chinese medicine fumigation packs, to be used while using a ventilator, without having to remove the breathing tubing and nasal mask / nose pillow, thus improving ease of use and expanding the application scenarios of the breathing tubing.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] This application provides a breathing hose, which includes a hose body 100, two hose connectors 200, and an mounting member 300. The hose body 100 has a flow channel for gas flow. The two hose connectors 200 are respectively located at both ends of the hose body 100. One of the hose connectors 200 is used to connect to the water tank of a ventilator, and the other is used to connect to a nasal mask 700 or a nasal pillow 800. The mounting member 300 is used to carry a medication pack. The mounting member 300 is located in the flow channel and abuts against the wall of the hose body 100 to divide the flow channel into a first channel and a second channel. The mounting member 300 is provided with a first through hole 310 connecting the first channel and the second channel.

[0043] The aforementioned breathing hose has connectors 200 at both ends of the hose body 100, allowing one end of the hose body 100 to connect to the air outlet of the water tank and the other end to the nasal mask 700 or nasal pillow 800. When using the ventilator, the airflow generated by the ventilator unit is humidified by the water tank and then flows through the flow channel of the hose body 100 to the nasal mask 700 / nasal pillow 800, ultimately reaching the user's nasal cavity. A mounting piece 300 is installed within the flow channel to hold the medication pack. The mounting piece 300 abuts against the wall of the hose body 100, dividing the flow channel into a first channel and a second channel. A first through hole 310 is provided in the mounting piece 300 to connect the first and second channels, thus enabling gas flow. The breathing tubing of this application, by setting an installation component 300 in the flow channel, with the installation component 300 carrying a medicine pack, allows gas to flow through the medicine pack when it flows through the flow channel, and the gas after flowing through the medicine pack can also flow into the nasal mask 700 / nasal pillow 800, and then into the user's nasal cavity. This allows other medications, such as rhinitis medication or traditional Chinese medicine fumigation packs, to be used while using a ventilator, without having to remove the breathing tubing and nasal mask 700 / nasal pillow 800, thus improving ease of use and expanding the application scenarios of the breathing tubing.

[0044] In one example, the mounting component 300 is located within the flow channel and near the side of the ventilator's water tank.

[0045] In one example, the mounting element 300 is located within the flow channel, near the side of the nasal mask 700 / nasal pillow 800. It is understood that the specific location of the mounting element 300 is determined based on the user's requirements and habits.

[0046] In one embodiment of this application, as Figure 2 As shown, the mounting component 300 includes an annular abutment plate and multiple support strips. The annular abutment plate abuts against the pipe wall, and the multiple support strips are all disposed within the inner ring of the annular abutment plate and connected to the annular abutment plate. A first through hole 310 is formed between two adjacent support strips. By disposing of multiple support strips within the inner ring of the annular abutment plate and connecting them to the inner ring of the annular abutment plate, multiple support strips are connected through the annular abutment plate. Furthermore, by having the annular abutment plate abut against the pipe wall, the multiple support strips are thus positioned within the flow channel.

[0047] It should be noted that the annular abutment plate abuts against the pipe wall, that is, the annular abutment plate is interference-fitted with the pipe wall to prevent the installation part 300 from shaking in the flow channel, thereby reducing the shaking of the drug pack in the flow channel.

[0048] Specifically, multiple support bars are arranged at radial intervals along the annular abutment plate.

[0049] In one embodiment of this application, such as Figure 2 and Figure 3As shown, the breathing hose also includes a sealing cap 400, which is fastened to one end of the tubing body 100. The sealing cap 400 and the mounting component 300 enclose an installation space for accommodating the medication pack. The sealing cap 400 has a second through hole 410. By setting the sealing cap 400 at one end of the tubing body 100 and fastening it to the tubing body 100, the sealing cap 400 and the mounting component 300 enclose an installation space, which can be placed within the installation space, further reducing the movement of the medication pack in the flow channel. Moreover, the sealing cap 400 has a second through hole 410, which communicates with the first through hole 310 and the flow channel, allowing airflow to pass normally through the flow channel.

[0050] In one example, such as Figure 2 and Figure 3 As shown, the sealing cover 400 is provided with a plurality of second through holes 410, which are strip-shaped holes, thereby increasing the flow velocity of the airflow through the sealing cover 400.

[0051] In one example, such as Figure 2 and Figure 3 As shown, the plugging cap 400 is provided with a snap-fit ​​part 420, and the outer peripheral surface of the pipeline body 100 is provided with a mating part. The snap-fit ​​part 420 is snapped into the mating part, thereby realizing the connection between the plugging cap 400 and the pipeline body 100.

[0052] In one example, such as Figure 2 and Figure 3 As shown, multiple snap-fit ​​parts 420 are arranged circumferentially around the sealing cap 400, and multiple mating parts are arranged circumferentially around the pipeline body 100, with each snap-fit ​​part 420 and mating part corresponding to another. By setting multiple snap-fit ​​parts 420 and multiple mating parts, the installation stability of the sealing cap 400 and the pipeline body 100 is improved.

[0053] Pipe fitting 200 is fitted onto one end of pipe body 100. To prevent interference between pipe fitting 200, one end of pipe body 100, and sealing cap 400, such as... Figure 2 and Figure 3As shown, a first annular protrusion 110 is provided on the outer circumferential surface of the pipeline body 100, and the first annular protrusion 110 is located on the side of the mating part away from the sealing cap 400; a second annular protrusion 210 is provided on the inner circumferential surface of the pipeline connector 200, the pipeline connector 200 is sleeved on the pipeline body 100, and the second annular protrusion 210 overlaps with the first annular protrusion 110. That is, when installing the sealing cap 400 and the pipeline connector 200 on the pipeline body 100, the sealing cap 400 is installed first, so that the sealing cap 400 is fastened to the end of the pipeline body 100, and then the pipeline connector 200 is sleeved on the end of the pipeline body 100 and the sealing cap 400, and the second annular protrusion 210 of the pipeline connector 200 overlaps with the first annular protrusion 110, thereby realizing the connection between the pipeline connector 200 and the pipeline body 100.

[0054] In one embodiment of this application, as Figure 2 and Figure 3 As shown, a first limiting boss 120 is provided on the pipe body 100, and a second limiting boss 220 extending radially outward is provided on the end face of the pipe connector 200. The pipe connector 200 is sleeved on the pipe body 100, and the second limiting boss 220 abuts against the first limiting boss 120. By providing the first limiting boss 120 and the second limiting boss 220, when the pipe connector 200 is sleeved on the pipe body 100, the second limiting boss 220 abuts against the first limiting boss 120, thereby further defining the relative position of the pipe connector 200 and the pipe body 100.

[0055] In one example, such as Figure 2 and Figure 3 As shown, when the pipe connector 200 is fitted onto the pipe body 100, the second limiting boss 220 is located between the first annular boss 110 and the first limiting boss 120.

[0056] Furthermore, in order to heat the gas within the flow channel and to activate the efficacy of the medication package carried on the mounting component 300, the breathing hose also includes a heating element disposed on the pipe body 100. The heating element is used to heat the gas within the flow channel. By installing a heating element on the pipe body 100 to heat the temperature of the gas within the flow channel, the gas within the flow channel is brought to a preset temperature, which not only reduces the irritation of cold gas to the nasal cavity but also activates the efficacy of the medication package carried on the mounting component 300.

[0057] In one example, the heating element is a heating wire, which is wound around the outer circumferential surface of the pipe body 100.

[0058] In one example, the heating element is a heating wire, which is embedded in the flow channel of the pipe body 100.

[0059] In one example, the heating element is a heating film, which is attached to the pipe body 100.

[0060] In one example, the heating element is a heating wire, which is located on the outer peripheral surface of the pipe body 100, and the heating wire and the pipe body 100 are integrally injection molded.

[0061] In one example, the heating element is a heating wire, which is embedded in the flow channel of the pipe body 100, and the heating wire and the pipe body 100 are integrally injection molded.

[0062] In one example, the heating element is a heating film, and the heating film and the pipeline body 100 are integrally injection molded.

[0063] Furthermore, such as Figure 2 As shown, a temperature detection element is provided on the pipeline body 100, and the temperature sensor 500 is used to detect the gas temperature in the flow channel.

[0064] Furthermore, such as Figure 2 As shown, a humidity detection device is provided on the pipeline body 100, and a temperature sensor 500 is used to detect the humidity of the gas in the flow channel.

[0065] One embodiment of this application also provides a breathing assembly, such as... Figure 4 and Figure 5 As shown, the breathing assembly includes a nasal interface and a breathing hose of any of the above, with one of the two tubing connectors 200 connected to the nasal interface, which is either a nasal mask 700 or a nasal pillow 800.

[0066] In one example, such as Figure 4 As shown, one of the tubing interfaces of the breathing hose is connected to the nasal mask 700.

[0067] In one example, such as Figure 5 As shown, one of the tubing interfaces of the breathing hose is connected to the nasal pillow 800.

[0068] It should be noted that the nasal mask 700 and nasal pillow 800 are two different types of interfaces used in respiratory therapy devices, primarily for providing continuous positive airway ventilation (such as CPAP therapy) or oxygen therapy.

[0069] A nose mask 700 is a face mask that covers the user's nose and typically includes a soft sealing pad that fits below the nostrils, above the upper lip, and on both sides of the cheeks to form a closed space. This design allows pressurized air or other gases to be delivered to the user through the mask.

[0070] A nose pillow 800 is a small interface that inserts directly into the nostril, delivering pressurized air or other gases by gently sealing the nostril. A nose pillow 800 is typically attached to a smaller frame or headband system to ensure its position is secure.

[0071] One embodiment of this application also provides a ventilator, including a main unit, a water tank, and the aforementioned breathing assembly. The air outlet of the water tank is connected to another pipe connector 200. A heat-conducting component is provided at the bottom of the water tank, and a heating component is provided on the main unit, which is in contact with the heat-conducting component. The heat-conducting component is used to conduct heat from the heating component to the liquid in the water tank, humidifying and heating the liquid. When the ventilator is working, the fan of the main unit draws in air, and the airflow generated by the fan passes through the water tank, flows out through the breathing hose, and flows into the user's nasal cavity through the nasal mask 700 / nasal pillow 800. Moreover, an mounting part 300 is provided on the tubing body 100 of the breathing hose, and the user can place a medicine pack on the mounting part 300 as needed, so that other medications, such as rhinitis medication or traditional Chinese medicine fumigation packs, can be used while using the ventilator without removing the breathing assembly, improving the convenience of use.

[0072] 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.

[0073] 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.
