[0002] Cleaning, disinfection, and maintenance of ventilation therapy equipment are crucial for its safe and reliable clinical application and for extending its lifespan. These are essential considerations for both users and clinical engineers. To prevent microbial contamination, in addition to implementing multiple filtration systems, reusable components of the ventilation therapy equipment should be regularly disinfected.

[0052] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] In this invention, unless otherwise stated, directional terms such as "up," "down," "left," "right," "front," and "back" generally refer to the orientation shown in the accompanying drawings. "Inner" and "outer" refer to the inner and outer contours of each component itself.

[0054] The present invention provides a disinfection device 300, including a first power unit 310, a heating unit 320 and a gas transfer unit 330. The first power unit 310 is used to supply gas to the gas transfer unit 330. The heating unit 320 is disposed between the first power unit 310 and the gas transfer unit 330 to heat the gas to form high-temperature disinfection gas. The gas transfer unit 330 is used to pass the high-temperature disinfection gas into the air passage of the equipment to be disinfected.

[0055] In the above description, the device to be disinfected can be any device with an airway that requires disinfection, such as a ventilation therapy device. The heating unit 320 heats the gas from the first power unit 310 to form a high-temperature disinfecting gas. This high-temperature disinfecting gas then enters the gas transfer unit 330, which in turn passes it into the airway of the device to be disinfected, disinfecting the entire airway. The gas provided by the first power unit 310 can be air, and the high-temperature disinfecting gas is high-temperature dry hot air.

[0056] The disinfection device 300 of the present invention uses high-temperature dry heat gas for disinfection, which can achieve all-round disinfection of the entire airway, with no dead corners and no residues, high safety, simple operation and low cost. When the disinfection device is used for disinfection of the airway of ventilation therapy equipment, it can completely solve the risk of bacteria inside the ventilation therapy equipment when the patient uses it.

[0057] The embodiments of the first power unit 310, the heating unit 320, and the gas transfer unit 330 are described in detail below with reference to the accompanying drawings. It should be noted that the first power unit 310, the heating unit 320, and the gas transfer unit 330 are not limited to the embodiments described below, but may also be other embodiments capable of achieving the above functions.

[0058] According to one embodiment of the first power unit 310 of the present invention, the first power unit 310 may include a first fan 311, the first fan 311 having a first fan inlet 3111 and a first fan outlet 3112 (see...). Figure 6 ).

[0059] Furthermore, to facilitate the integration and installation of the first fan 311 with other structures, and to protect the first fan 311, see [reference needed]. Figures 3-5 The first power unit 310 may further include a housing 312. The housing 312 includes a mounting cavity 3121 and a housing air inlet 3122 and a housing air outlet 3123 communicating with the mounting cavity 3121. A first fan 311 can be installed within the mounting cavity 3121. The first fan air inlet 3111 is correspondingly connected to the housing air inlet 3122, and the first fan air outlet 3112 is correspondingly connected to the housing air outlet 3123. The housing 312 may have any suitable shape. For example... Figure 6 As shown, the first fan inlet 3111 can extend outside the housing inlet 3122 to improve gas supply efficiency. Of course, a filter can also be installed at the first fan inlet 3111 or the housing inlet 3122 to filter the incoming gas.

[0060] Additionally, the first power unit 310 may also include a power connector 313, which can be connected to an external power source to supply power to the first fan 311. The power connector 313 can be mounted on the housing 312, such as... Figure 1 and Figure 2 As shown. Of course, the power connector 313 can also be used to supply power to the heating unit 320. The power connector 313 can be any existing type of connector, such as a fixed type or a type with a cable plug.

[0061] According to one embodiment of the gas transfer unit 330 of the present invention, see [reference needed]. Figures 3-5 The gas transfer unit 330 may include a transfer housing 331, which includes a transfer cavity 3311, an air inlet 3312 and an air outlet 3313 connected to the transfer cavity 3311. The air inlet 3312 is connected to the air outlet 3112 of the first fan, and the air outlet 3313 is connected to the air duct of the equipment to be disinfected.

[0062] The transfer shell 331 can be of any shape. To enable simultaneous sterilization of multiple devices, the transfer shell 331 may include multiple air outlets 3313, each of which can be connected to one device to be sterilized. Specifically, for example… Figure 1 As shown, the transfer housing 331 can be a square body, and the front, rear, left, right and top sides of the transfer housing 331 can be respectively provided with transfer housing air outlets 3313.

[0063] The multiple air outlets 3313 of the transfer housing can have the same shape and different dimensions to accommodate devices with different standard interface sizes. Of course, in actual use, each air outlet 3313 of the transfer housing can be equipped with an adapter with different diameters or a multi-connector to facilitate connection to devices with different pipe diameters or multiple devices.

[0064] Furthermore, the gas transfer unit 330 may also include a sealing plug 332, which is detachably sealed to the gas outlet 3313 of the transfer housing. The number of sealing plugs 332 may be equal to the number of gas outlets 3313 of the transfer housing.

[0065] When in use, the sealing plug 332 on the air outlet 3313 of the transfer shell used to connect with the equipment to be disinfected can be removed, and the other air outlets 3313 of the transfer shell can be sealed with sealing plugs 332.

[0066] For example Figure 6 In the embodiment shown, when disinfecting a device to be disinfected, one of the air outlets 3313 of the transfer housing is opened, and the air outlets 3313 of the remaining transfer housings are sealed with sealing plugs 332. The gas flow is as follows: Figure 6 As indicated by the middle arrow.

[0067] For example Figure 7 In the embodiment shown, when disinfecting two devices to be disinfected, two of the transfer shell air outlets 3313 are opened, and the remaining transfer shell air outlets 3313 are sealed with sealing plugs 332. The gas flow is as follows: Figure 7 As indicated by the middle arrow.

[0068] For example Figure 8 In the embodiment shown, when disinfecting three devices to be disinfected, three of the transfer shell air outlets 3313 are opened, and the remaining transfer shell air outlets 3313 are sealed with sealing plugs 332. The gas flow is as follows: Figure 8 As indicated by the middle arrow.

[0069] In this invention, the sealing plug 332 is preferably made of elastic, deformable, and sealable materials such as silicone or rubber. To facilitate rapid assembly of the sealing plug 332 with the air outlet 3313 of the transfer housing, the insertion end of the sealing plug 332 may be provided with a guide structure, such as a guide ramp. Additionally, the insertion end of the sealing plug 332 may be configured as a hollow structure to facilitate sealing, deformation, and insertion / removal. For the specific structure of the sealing plug 332, please refer to [reference needed]. Figure 3 The implementation method shown.

[0070] According to one embodiment of the heating unit 320 of the present invention, the heating unit 320 may include a heating element 321, which is disposed on the communication passage between the first fan outlet 3112 and the intermediate housing outlet 3313.

[0071] The heating element 321 can be understood as a component that generates heat when energized, thereby heating the gas. For example, the heating element 321 can be made of materials such as iron-chromium-aluminum alloy, nickel-chromium alloy, or copper wire. The heating element 321 can have any suitable shape, such as a sheet (e.g.,...). Figure 4 As shown), filamentous (i.e., heating wire), etc.

[0072] The temperature of the high-temperature sterilization gas obtained by the heating unit 320 is preferably not lower than 60°C, and more preferably 70-85°C.

[0073] Furthermore, to facilitate the installation of the heating element 321, the heating unit 320 may also include a mounting cylinder 322. One end of the mounting cylinder 322 is sealed and connected to the air outlet 3112 of the first fan, and the other end of the mounting cylinder 322 is sealed and connected to the air inlet 3312 of the transfer housing. The heating element 321 is installed inside the mounting cylinder 322 (see [reference]). Figure 5 and Figure 6 Of course, in other embodiments, the heating element 321 can be directly installed at the air inlet 3312 of the transfer housing or the air outlet 3123 of the outer housing. The heating element 321 can also be installed in other ways on the connecting passage between the air outlet 3112 of the first fan and the air outlet 3313 of the transfer housing.

[0074] In addition, the heating unit 320 may also include a one-way valve 323 to ensure that the gas flows unidirectionally from the outlet 3112 of the first fan to the inlet 3312 of the intermediate housing. The one-way valve 323 can be installed inside the mounting cylinder 322. By integrating the heating element 321, the one-way valve 323, and the mounting cylinder 322 into one unit, this invention facilitates installation, maintenance, and cooperation with other structures.

[0075] To ensure that the disinfection device 300 has a compact structure, reasonable layout, and small space occupation, such as Figure 6 As shown, the heating unit 320 can also be installed in the mounting cavity 3121 of the outer casing 312. The upper end of the mounting cylinder 322 is connected to the air outlet 3123 of the outer casing and to the air inlet 3312 of the transfer shell.

[0076] It should be noted that the connections between each air inlet and outlet in this invention are all sealed connections to prevent gas leakage, ensure efficient gas supply, and facilitate gas control.

[0077] In this invention, the disinfection device 300 may further include a first gas monitor 333, which may be installed in the transfer chamber 3311 to monitor the properties of the high-temperature disinfection gas, such as temperature, humidity, pressure, flow rate, and velocity.

[0078] The first gas monitor 333 can be installed at any position within the transfer chamber 3311. There can also be multiple first gas monitors 333. For example, the first gas monitors 333 can be installed at the air inlet and air outlet of the transfer chamber 3311 respectively to monitor the properties of the incoming and outgoing gases.

[0079] In this invention, the disinfection device 300 may further include a control unit. The first gas monitor 333 can transmit the monitored information to the control unit. The control unit can control the operation of the heating element 321 and the first fan 311 according to the information monitored by the first gas monitor 333, so as to realize the control of the properties of the high-temperature disinfection gas.

[0080] The disinfection device 300 of the present invention can have two working modes: disinfection mode and cooling mode.

[0081] Specifically, when the disinfection mode is activated, the first fan 311 operates to supply gas to the heating unit 320. The control unit controls the heating element 321 to heat the gas from the first fan 311 to form high-temperature disinfection gas. Then, the high-temperature disinfection gas enters the transfer chamber 3311 through the one-way valve 323, and then enters the air passage of the equipment to be disinfected through the air outlet 3313 of the transfer shell for high-temperature disinfection.

[0082] When switching to cooling mode, the operation is the same as disinfection mode, but the control unit controls the heating element 321 to not heat up, so that the room temperature gas from the first fan 311 directly enters the transfer chamber 3311 and then enters the airway of the device to be disinfected, quickly taking away the heat in the airway and cooling the entire airway, so that the patient can use the device to be disinfected in a timely manner.

[0083] The interface connecting the device to be disinfected to the air outlet 3313 of the transfer housing can be considered as the air inlet of the device, and the other end of the air passage of the device can be considered as the air outlet. In actual use, it is best to install a flow restrictor, such as a flow valve, at the air outlet of the device to be disinfected to control the output flow and avoid excessive flow that would reduce the disinfection effect.

[0084] In another aspect, the present invention provides a ventilation therapy device, including the above-mentioned disinfection device 300, which is used to introduce high-temperature disinfected gas into the airway of the ventilation therapy device.

[0085] Specifically, the ventilation therapy device may include a main unit 100 and a disinfection device 300. The main unit 100 is used to generate therapeutic gas and has a main unit air inlet 111 and a main unit air outlet 112. The disinfection device 300 is used to generate high-temperature disinfecting gas and is connected to the main unit air inlet 111 or the main unit air outlet 112 to introduce high-temperature disinfecting gas into the main unit 100 and the humidifier 200.

[0086] Furthermore, the ventilation therapy device may also include a humidifier 200 for humidifying the therapeutic gas. The humidifier 200 has a humidifier inlet 211 and a humidifier outlet 212, with the humidifier inlet 211 connected to the main unit outlet 112. A sterilization device 300 may be connected to the humidifier 200 for introducing high-temperature sterilization gas into the humidifier 200.

[0087] As can be understood from the above, the connection between the disinfection device 300 and the main unit 100 and the humidifier 200 can be in three ways: First, the disinfection device 300 is connected to the main unit 100, specifically to the main unit's air inlet 111, with the disinfection device 300 located on the side of the main unit 100, and the main unit's air outlet 112 directly connected to the humidifier's air inlet 211; Second, the disinfection device 300 is connected to the humidifier 200, specifically to the humidifier's air outlet 212, with the disinfection device 300 located on the side of the humidifier 200, and the main unit's air outlet 112 directly connected to the humidifier's air inlet 211 (see...). Figure 15The third type: The disinfection device 300 is connected to the main unit 100 and the humidifier 200, specifically to the air outlet 112 of the main unit and the air inlet 211 of the humidifier. In other words, the disinfection device 300 is located between the main unit 100 and the humidifier 200, and the air outlet 112 of the main unit and the air inlet 211 of the humidifier are indirectly connected through the disinfection device 300 (see...). Figure 9 , Figure 11 , Figure 13 or Figure 14 ).

[0088] In the first and second cases described above, the disinfection device 300 may have a transfer housing outlet 3313 (see Figure 15 In the third scenario described above, the disinfection device 300 may have two intermediate housing air outlets 3313, which are respectively connected to the main unit air outlet 112 and the humidifier air inlet 211 (see...). Figure 13 or Figure 14 ).

[0089] In this invention, see Figure 12 The main unit 100 may include a main unit housing 110 having a cavity 113 and a second power unit disposed within the cavity 113. The main unit air inlet 111 and the main unit air outlet 112 are disposed on the main unit housing 110 and communicate with the cavity 113.

[0090] Among them, see Figure 13 The second power unit may include a second fan 120, which has a second fan inlet 121 and a second fan outlet 122. The second fan inlet 121 is connected to the main unit inlet 111, and the second fan outlet 122 is connected to the main unit outlet 112.

[0091] In use, the second fan 120 can draw gas from outside the main unit's air inlet 111 into the second fan 120 in sequence through the main unit's air inlet 111 and the second fan's air inlet 121, and discharge the gas from the main unit 100 in sequence through the second fan's air outlet 122 and the main unit's air outlet 112.

[0092] In this invention, the main unit 100 may further include a main unit connector 150, which may be disposed on the main unit housing 110. The main unit connector 150 may be electrically connected to an external power source to supply power to the second fan 120. The power connector 313 of the disinfection device 300 may be connected to the main unit connector 150 to be powered by the main unit connector 150 (see [link]). Figure 13 ).

[0093] In this invention, the main unit 100 may further include a filter element 130, which is installed at the air inlet 111 of the main unit. The filter element 130 can be used to filter the gas entering the main unit 100, preventing dust, impurities, particulate matter, etc. from entering the main unit 100 and contaminating the main unit 100, and ultimately entering the patient's respiratory tract.

[0094] Since the second fan 120 will generate negative pressure at its air inlet 121 during operation, a limiting structure can be installed at the main unit's air inlet 111 to prevent the filter element 130 from entering the second fan 120 under negative pressure. Specifically, for example... Figure 12 and Figure 13 As shown, the limiting structure can be a stop 140 disposed inside the main unit air inlet 111, and the stop 140 is provided with a through hole for gas to pass through.

[0095] In this invention, see Figure 12 and Figure 13 The humidifier 200 includes a humidifier housing 210 with a humidification chamber 213, and a humidifier air inlet 211 and a humidifier air outlet 212 are disposed on the humidifier housing 210 and communicate with the humidification chamber 213.

[0096] In the above description, the humidification chamber 213 may store a liquid, such as water, to humidify the gas. To increase the water-passing area of ​​the gas within the humidification chamber 213, thereby improving the humidification rate, a guiding structure capable of guiding the gas to flow along a longer flow path can be provided within the humidification chamber 213. Specifically, for example… Figures 12-15 As shown, the guiding structure can be a guide plate 220. The gas entering the humidification chamber 213 through the humidifier inlet 211 can first flow downward along the guide plate 220, and then flow upward to the humidifier outlet 212 for discharge.

[0097] In this invention, the ventilation therapy device may further include a control unit, which may be the control unit of the disinfection device 300. This control unit is configured to control the operation of the first power unit 310, the second power unit, and the heating unit 320. In other words, the control unit is used to control the operation of the entire ventilation therapy device.

[0098] In this invention, the ventilation therapy device may further include a flow limiting unit 400, which may be located at the main unit air inlet 111 and / or the humidifier air outlet 212.

[0099] Specifically, when the disinfection device 300 is connected to the main unit's air inlet 111, the flow-limiting unit 400 can be installed at the humidifier's air outlet 212 to limit the airflow at the humidifier's air outlet 212; when the disinfection device 300 is connected to the humidifier's air outlet 212, the flow-limiting unit 400 can be installed at the main unit's air inlet 111 to limit the airflow at the main unit's air inlet 111 (see...). Figure 15 When the disinfection device 300 is connected between the main unit's air outlet 112 and the humidifier's air inlet 211, there can be two flow-limiting units 400, respectively located at the main unit's air inlet 111 and the humidifier's air outlet 212, to limit the airflow at the main unit's air inlet 111 and the humidifier's air outlet 212 (see...). Figure 11 ).

[0100] The flow-limiting unit 400 may include a flow-limiting element 410. The flow-limiting element 410 is configured to connect to the main unit's air inlet 111 or the humidifier's air outlet 212 to limit the flow rate of the high-temperature disinfecting gas discharged through the main unit's air inlet 111 or the humidifier's air outlet 212, preventing excessive flow and loss of disinfection effectiveness. The flow-limiting element 410 can have various implementations; for example, it can be a flow valve or something similar. Figure 11 and Figure 12 The cylindrical structure shown has one end that can be plugged into the main unit's air inlet 111 or the humidifier's air outlet 212, and the other end has an end wall with multiple vent holes.

[0101] Of course, in other embodiments, the ventilation therapy device may not have a separate flow limiting unit 400, but may use the large air resistance generated by the structure of the main unit or humidifier itself to achieve the flow limiting function.

[0102] To prevent burns or other injuries from the high-temperature sterilization gas discharged through the main unit's air inlet 111 or the humidifier's air outlet 212, the flow limiting unit 400 may include a protective component 420, which is configured to connect to the main unit's air inlet 111 or the humidifier's air outlet 212. Of course, the flow limiting component 410 may employ a design such as... Figure 11 and Figure 12 In the embodiment shown, the protective element 420 can be installed outside the flow restrictor 410.

[0103] Specifically, such as Figure 11 and Figure 12 As shown, the protective component 420 may include a protective cylinder 421, which is sleeved outside the flow restrictor 410.

[0104] Furthermore, in order to prevent fingers from entering the protective cylinder 421 or other objects from entering the protective cylinder 421 and causing blockage, an intercepting grille 422 may be provided at the end of the protective cylinder 421 away from the flow restrictor 410.

[0105] In this invention, the ventilation therapy device may further include a second gas monitor 430, which can be used to monitor the properties of the high-temperature disinfection gas discharged through the main unit air inlet 111 or the humidifier air outlet 212, so as to better control the operation of the disinfection device.

[0106] In this invention, the ventilation therapy device may further include a ventilation pipeline and a patient interface device. One end of the ventilation pipeline is connected to the patient interface device, and the other end of the ventilation pipeline may be connected to the humidifier outlet 212 or the transfer housing outlet 3313.

[0107] The ventilation therapy device of the present invention can have three working modes: treatment mode, disinfection mode, and cooling mode.

[0108] Specifically, with Figure 14 For example, when the treatment mode is activated, the first fan 311 and the one-way valve 323 are closed, and the second fan 120 is running. Figure 14 As shown by the middle arrow, the gas enters the second fan 120 through the main unit air inlet 111 and the second fan air inlet 121 in sequence. Then, it enters the transfer chamber 3311 through the second fan air outlet 122, the main unit air outlet 112, and the left transfer shell air outlet 3313 in sequence. After that, it enters the humidification chamber 213 through the right transfer shell air outlet 3313 and the humidifier air inlet 211 in sequence for humidification. After humidification, the gas enters the ventilation pipeline through the humidifier air outlet 212 and finally enters the patient interface device for the patient to inhale.

[0109] When disinfection mode is activated, see Figure 13 In the embodiment shown, the second fan 120 is in the off state, the first fan 311 and the one-way valve 323 are turned on, and the heating element 321 heats up, as shown. Figure 13 As shown by the middle arrow, gas enters the first fan 311 through the first fan inlet 3111, and then enters the mounting cylinder 322 through the first fan outlet 3113. The high-temperature sterilizing gas generated by the heating element 321 enters the transfer chamber 3311 through the one-way valve 323 and the transfer shell inlet 3312, and then enters the second fan 120 and the humidification chamber 213 through the transfer shell outlets 3313 on the left and right sides, respectively. After high-temperature sterilization of the main unit 100 and the humidifier 200, the gas is discharged through the main unit inlet 111 and the humidifier outlet 212. Of course, when the humidifier outlet 212 is connected to a ventilation pipeline and a patient interface device, the ventilation pipeline and the patient interface device can also be further sterilized at high temperature.

[0110] When disinfection mode is activated, see Figure 15 In the embodiment shown, the second fan 120 is in the off state, the first fan 311 and the one-way valve 323 are turned on, and the heating element 321 heats up, as shown. Figure 15 As shown by the middle arrow, the gas enters the first fan 311 through the first fan inlet 3111, and then enters the mounting cylinder 322 through the first fan outlet 3113. The high-temperature disinfection gas formed by the heating element 321 enters the transfer chamber 3311 through the one-way valve 323 and the transfer shell inlet 3312 in sequence. Then, it enters the humidification chamber 213 through the transfer shell outlet 3313 and the humidifier outlet 212 in sequence to disinfect the humidifier 200 at high temperature. After that, the high-temperature disinfection gas enters the second fan 120 through the humidifier inlet 211, the main unit outlet 112, and the second fan outlet 122 in sequence to disinfect the main unit 100 at high temperature, and then exits through the second fan inlet 121 and the main unit inlet 111 in sequence.

[0111] When the cooling mode is activated, the heating element 321 does not generate heat. The first fan 311 or the second fan 120 runs, drawing ambient temperature air into the ventilation therapy device to quickly remove heat from the device and cool the entire device.

[0112] In actual use, the ventilation therapy device can be set to activate the disinfection mode only when the humidifier outlet 212 is connected to the flow limiting unit 400. This can prevent the humidifier outlet 212 without the flow limiting unit 400 from being exposed to the air or connected to the ventilation pipeline, which could cause burns or other injuries to the user or patient.

[0113] Through the above technical solution, from the air inlet to the air outlet of the ventilation therapy device, the air breathed by the patient can be thoroughly disinfected through all airways inside the ventilation therapy device by the high-temperature disinfecting gas of the disinfection device. The disinfection is thorough and leaves no dead corners or residues, which can completely solve the risk of bacteria inside the ventilation therapy device when the patient uses it.

[0114] In this invention, the ventilation therapy device may be a ventilator, an oxygen therapy device, etc.

[0115] In this invention, see Figure 16 The ventilation therapy device may also include a disinfection pipeline 500, the two ends of which can be detachably connected and communicated with the main unit 100 and the disinfection device 300 respectively, so as to form a channel for the circulation of high-temperature disinfection gas together with the main unit 100 and the disinfection device 300.

[0116] It should be noted that the connection between the disinfection pipeline 500 and the main unit 100 and the disinfection device 300 can be direct or indirect. For example, in... Figure 16 In the illustrated embodiment, the two ends of the disinfection pipeline 500 are directly and detachably connected to the main unit 100 and the disinfection device 300, respectively, specifically connected to the air inlet 111 of the main unit and the air outlet 3313 of the transfer housing; for example, in Figure 9In the embodiment shown, the two ends of the disinfection pipeline 500 are directly and detachably connected to the main unit 100 and the humidifier 200 respectively (specifically, connected to the air inlet 111 of the main unit and the air outlet 212 of the humidifier), and are indirectly connected to the disinfection device 300.

[0117] In addition, to improve the temperature uniformity of the high-temperature disinfection gas throughout the channel and ensure the disinfection effect, a heating unit 320 can be installed inside the main unit 100, such as... Figure 16 As shown.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0119] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0120] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
