Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a humidification assembly and a ventilator having therein. Background Technology

[0002] A ventilator, a medical device that can replace or assist patients in completing mechanical ventilation, improves respiratory function, reduces the work of breathing, and conserves cardiac reserve. It is mainly used in homes, sleep therapy centers, and some clinics and hospitals. To reduce the irritation of cold, dry air on the respiratory mucosa, most ventilators are equipped with humidification components. By heating water, they generate water vapor, making the air inhaled by the user warm and humid.

[0003] In existing humidification components, an air inlet and an air outlet are usually opened on the shell to connect the liquid storage chamber. In order to shorten the air path, the air inlet and the air outlet are set up adjacent to each other. This causes the external air to flow into the liquid storage chamber through the air inlet, be humidified briefly in the liquid storage chamber, and then flow out from the air outlet, resulting in low humidification efficiency of the humidification component. Summary of the Invention

[0004] The purpose of this invention is to provide a humidification component with high humidification efficiency.

[0005] To achieve one of the above-mentioned objectives, one embodiment of the present invention provides a humidification component, including a housing forming a liquid storage chamber. The housing has an air inlet and an air outlet communicating with the liquid storage chamber. The housing also has an air inlet exposed in the liquid storage chamber, an air inlet channel connecting the air inlet and the air outlet, an air outlet exposed in the liquid storage chamber, and an air outlet channel connecting the air outlet and the air outlet. The air inlet is open to the side opposite to the air outlet, and the air outlet is open to the side opposite to the air inlet.

[0008] As a further improvement of one embodiment of the present invention, the air intake channel further includes an air intake chamber, and the air guide shell further includes an air intake hole connecting the air intake passage and the air intake chamber. The air intake port is exposed in the air intake chamber, and the axis of the air intake port is set at a certain angle to the axis of the air intake hole.

[0009] As a further improvement of one embodiment of the present invention, the air outlet channel further includes an air outlet cavity, and the guide shell further includes an air outlet hole connecting the air outlet passage and the air outlet cavity. The air outlet is exposed in the air outlet cavity, and the axis of the air outlet is set at a certain angle to the axis of the air outlet hole.

[0010] As a further improvement of one embodiment of the present invention, the air inlet pipe has a first bottom wall opposite to the air inlet hole, and the air outlet pipe has a second bottom wall opposite to the air outlet hole. The horizontal height of the first bottom wall gradually decreases from the air inlet hole toward the air inlet, and the horizontal height of the second bottom wall gradually decreases from the air outlet hole toward the air outlet.

[0011] As a further improvement of one embodiment of the present invention, the axis of the air inlet is set at a certain angle to the axis of the air inlet, and the axis of the air outlet is set at a certain angle to the axis of the air outlet.

[0012] As a further improvement of one embodiment of the present invention, the housing further includes an air inlet pipe connected to the upper housing and connected to the air inlet, and an air outlet pipe connected to the upper housing and connected to the air outlet. The axis of the air inlet pipe is set at a certain angle to the axis of the air inlet, and the axis of the air outlet pipe is set at a certain angle to the axis of the air outlet.

[0014] As a further improvement of one embodiment of the present invention, the housing further includes a lower housing connected to the upper housing, and the humidification assembly further includes a protective member connected to the lower housing, with the upper housing abutting against the protective member.

[0015] To achieve the objectives of the invention described above, the present invention also provides a ventilator, which includes the humidification component as described above.

[0016] Compared with the prior art, in the embodiments of the present invention, external air flows into the liquid storage chamber through the air inlet for humidification, and the humidified gas is discharged from the liquid storage chamber through the air outlet. Since the air inlet and the air outlet are open and facing away from each other, the humidification time of the external gas in the liquid storage chamber is increased, thereby improving the humidification efficiency of the humidification component.

[0025] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0026] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] It should be understood that terms such as "upper," "lower," "outer," and "inner," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0028] The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein shall be interpreted accordingly. For ease of description, in this invention, when the humidifying component is in normal use, the direction facing the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is horizontal, and the direction perpendicular to the ground is vertical; the side closer to the user is the front side, and the side farther from the user is the rear side.

[0029] refer to Figures 1 to 8As shown, a preferred embodiment of the present invention provides a humidification component that, when used in a ventilator, can humidify (or humidify and heat) the gas input from the fan assembly, and the completed gas is delivered to the breathing mask for user use.

[0030] Reference Figure 1 and Figure 2 As shown, specifically, a humidification assembly includes a housing 10 forming a liquid storage chamber 101. The housing 10 has an air inlet 102 and an air outlet 103 communicating with the liquid storage chamber 101. In this embodiment, the liquid storage chamber 101 can contain a humidifying liquid, such as water. The air inlet 102 is connected to the exhaust port of a fan assembly, thereby introducing the gas to be humidified into the liquid storage chamber 101 for humidification. The air outlet 103 is connected to the air output port of a ventilator, thereby delivering the humidified gas in the liquid storage chamber 101 to a breathing mask.

[0031] Furthermore, the housing 10 also has an air inlet 104 exposed in the liquid storage chamber 101, an air inlet channel connecting the air inlet 102 and the air inlet 104, an air outlet 106 exposed in the liquid storage chamber 101, and an air outlet channel connecting the air outlet 103 and the air outlet 106. In this embodiment, as... Figure 2 The air inlet 104 and air outlet 106 are exposed within the liquid storage chamber 101, specifically meaning that the air inlet 104 and air outlet 106 are directly connected to the liquid storage chamber 101. The gas to be humidified flows from the air inlet 102 through the air intake channel, then flows from the air inlet 104 into the liquid storage chamber 101 for humidification. After humidification is complete in the liquid storage chamber 101, the gas flows through the air outlet 106 to the air outlet channel, and then flows out from the air outlet 103.

[0032] Reference Figure 3 and Figure 4 As shown, furthermore, the air inlet 104 is open on the side opposite to the air outlet 106, and the air outlet 106 is open on the side opposite to the air inlet 104. In this embodiment, as... Figure 2 and Figure 4 The opening direction of the air inlet 104 is opposite to the opening direction of the air outlet 106. For example, the opening direction of the air inlet 104 is to the left, and the opening direction of the air outlet 106 is to the right. Therefore, the gas flowing into the liquid storage chamber 101 from the air inlet 104 first flows to the left and downwards, then to the right and upwards, and finally flows out of the liquid storage chamber 101 from the air outlet 106. Subsequently, the gas to be humidified forms a circulating airflow covering the entire liquid storage chamber 101, increasing the humidification time of the gas in the liquid storage chamber 101 and improving the humidification efficiency of the humidification component.

[0033] Of course, in some embodiments, the air inlet 104 may open forward and the air outlet 106 may open backward.

[0034] Reference Figure 5 As shown, the housing 10 includes an upper shell 11 forming an air inlet 102 and an air outlet 103, and a flow guide shell 12 connected to the upper shell 11. In this embodiment, the upper shell 11 and the flow guide shell 12 are detachably connected, for example, by a snap-fit ​​connection. The flow guide shell 12 is exposed inside the liquid storage chamber 101.

[0035] Specifically, the air inlet 104 and the air outlet 106 are formed on opposite sides of the guide shell 12. In this embodiment, the air inlet 104 and the air outlet 106 are formed on the guide shell 12, and the air intake channel and the air outlet channel are formed between the upper shell 11 and the guide shell 12, thereby reducing the manufacturing difficulty of the shell 10 and saving manufacturing costs.

[0036] Moreover, the air inlet 104 and the air outlet 106 are located on opposite sides of the guide shell 12, thereby maximizing the distance between the air inlet 104 and the air outlet 106, increasing the humidification time of the gas in the liquid storage chamber 101, and improving the humidification efficiency of the humidification component.

[0037] Of course, in embodiments not shown, the housing 10 may also be manufactured in a one-piece molding manner.

[0038] Specifically, the air intake channel includes an air intake passage 1051, and the air inlet 104 is exposed within the air intake passage 1051. In this embodiment, as... Figure 2 The air inlet 104 is exposed within the air intake passage 1051, specifically meaning that the air inlet 104 is directly connected to the air intake passage 1051. Thus, the gas to be humidified that flows in through the air inlet 102 passes through the air intake passage 1051 and then flows into the liquid storage chamber 101 from the air inlet 104.

[0039] Specifically, the air outlet channel includes an air outlet passage 1071, and the air outlet 106 is exposed within the air outlet passage 1071. In this embodiment, as... Figure 3 The air outlet 106 is exposed within the air outlet passage 1071, specifically meaning that the air outlet 106 is directly connected to the air outlet passage 1071. Thus, the gas that has been humidified in the liquid storage chamber 101 flows into the air outlet passage 1071 through the air outlet 106 and finally flows out from the air outlet 103.

[0040] Specifically, the guide shell 12 includes an air inlet pipe 121 forming an air inlet passage 1051 and an air outlet pipe 122 forming an air outlet passage 1071. In this embodiment, both the air inlet pipe 121 and the air outlet pipe 122 adopt a tubular structure, such as a tubular structure with a variable inner diameter, which reduces the resistance encountered by the airflow in the air inlet passage 1051 and the air outlet passage 1071.

[0041] Furthermore, the air inlet pipe 121 and the air outlet pipe 122 also serve to isolate the gas, that is, to separate the gas to be humidified from the humidified gas, to prevent the humidified gas from coming into contact with the gas to be humidified when it is output, to avoid mutual interference between the gas to be humidified and the humidified gas, and to ensure the humidification effect of the output gas.

[0042] Furthermore, the plane of symmetry of the air inlet duct 121 is parallel to the plane of symmetry of the air outlet duct 122. In this embodiment, as... Figure 4 The air inlet pipe 121 is symmetrical along the front-to-back direction, and the air outlet pipe 122 is also symmetrical along the front-to-back direction. Preferably, the airflow direction in the air inlet passage 1051 flows from the upper right to the lower left, and the airflow direction in the air outlet passage 1071 flows from the lower right to the upper left. Both airflow directions are at a certain angle to the horizontal direction, which makes the airflow circulation into and out of the liquid storage chamber 101 smoother, ensuring the humidification effect while improving the kinetic energy of the output humidifying gas.

[0043] In addition, the design of the air inlet pipe 121 and the air outlet pipe 122 enables the humidifier unit to have an anti-backflow function, preventing water from flowing back into the fan assembly after the ventilator is tilted at a certain angle, causing water damage to the components inside the fan assembly, or preventing water from flowing back into the breathing mask after the ventilator is tilted at a certain angle, thus affecting the user's experience.

[0044] Continue to cooperate with reference Figure 2 As shown, specifically, the air intake channel further includes an air intake chamber 1052, and the guide shell 12 further includes an air intake hole 124 connecting the air intake passage 1051 and the air intake chamber 1052. The air inlet 102 is exposed inside the air intake chamber 1052. In this embodiment, the air inlet 102 being exposed inside the air intake chamber 1052 specifically means that the air inlet 102 is directly connected to the air intake chamber 1052. Thus, the gas flowing in through the air inlet 102 first passes through the air intake chamber 1052, then flows into the air intake passage 1051 through the air intake hole 124, and finally flows into the liquid storage chamber 101 through the air inlet 104.

[0045] Furthermore, the axis of the air inlet 102 is set at a certain angle to the axis of the air inlet 124. In this embodiment, the airflow direction flowing into the air inlet chamber 1052 from the air inlet 102 is parallel to the axis of the air inlet 102, and the airflow direction flowing out of the air inlet chamber 1052 from the air inlet 124 is parallel to the axis of the air inlet 124. Moreover, preferably, the axis of the air inlet 102 and the axis of the air inlet 124 are perpendicular to each other. Thus, the airflow directions flowing into and out of the air inlet chamber 1052 are different, that is, the gas flow changes direction after passing through the air inlet chamber 1052. Consequently, the airflow velocity flowing into the liquid storage chamber 101 from the air inlet 102 is weakened by the air inlet chamber 1052 after passing through it, increasing the gas humidification time and reducing the noise generated by the high-speed gas flow.

[0046] Furthermore, the inner diameter of the air inlet 102 is smaller than that of the air inlet cavity 1052, resulting in a reduced airflow velocity after the airflow enters the air inlet cavity 1052, thus reducing the noise generated by the high-speed gas flow. Some of the noise generated by the fan assembly flows into the air inlet cavity 1052 with the airflow, and is redirected after passing through the air inlet cavity 1052. This redirection process impacts the cavity wall of the air inlet cavity 1052, and the reflected noise airflow partially cancels out the noise, preventing the noisy airflow from directly entering the liquid storage cavity 101. Additionally, since the air inlet cavity 1052 is located inside the housing 10 (inside the liquid storage cavity 101), when the airflow impacts the cavity wall of the air inlet cavity 1052 and generates noise, the housing 10 can isolate this noise within the liquid storage cavity 101, preventing the noise from directly radiating to the outside of the ventilator and reducing the overall noise of the ventilator.

[0047] Continue to cooperate with reference Figure 3 As shown, specifically, the air outlet channel further includes an air outlet chamber 1072, and the guide shell 12 further includes an air outlet hole 125 connecting the air outlet passage 1071 and the air outlet chamber 1072. The air outlet 103 is exposed inside the air outlet chamber 1072. In this embodiment, the air outlet 103 being exposed inside the air outlet chamber 1072 specifically means that the air outlet 103 is directly connected to the air outlet chamber 1072. Thus, the gas flowing out through the air outlet 106 first passes through the air outlet passage 1071, then flows into the air outlet chamber 1072 through the air outlet hole 125, and finally flows out through the air outlet 103.

[0048] Furthermore, the axis of the air outlet 103 is set at a certain angle to the axis of the air outlet 125. In this embodiment, the airflow direction flowing into the air outlet chamber 1072 from the air outlet 125 is parallel to the axis of the air outlet 125, and the airflow direction flowing out of the air outlet chamber 1072 from the air outlet 103 is parallel to the axis of the air outlet 103. Preferably, the axis of the air outlet 103 is perpendicular to the axis of the air outlet 125. Thus, the airflow directions flowing into and out of the air outlet chamber 1072 are different, meaning the gas flow changes direction after passing through the air outlet chamber 1072. Consequently, the airflow velocity flowing out of the liquid storage chamber 101 from the air outlet 106 is weakened by the air outlet chamber 1072 after passing through it, increasing the gas humidification time and reducing the noise generated by high-speed gas flow.

[0049] Similarly, the exhaust chamber 1072 has a noise reduction function that communicates with the intake chamber 1052, which will not be elaborated here.

[0050] Furthermore, the design of the air inlet chamber 1052 and the air outlet chamber 1072, which change the direction of gas flow, can prevent the liquid in the liquid storage chamber 101 from flowing out when the humidification component is tilted or overturned, that is, prevent the liquid in the liquid storage chamber 101 from flowing to the fan component or the mask, thus realizing the backflow prevention function of the humidification component.

[0051] Specifically, the air inlet pipe 121 has a first bottom wall 126 opposite to the air inlet hole 124, and the air outlet pipe 122 has a second bottom wall 127 opposite to the air outlet hole 125. In this embodiment, as... Figure 2 The first bottom wall 126 is located at the bottom of the air inlet duct 121. For example... Figure 3 The second bottom wall 127 is located at the bottom of the air outlet duct 122.

[0052] Furthermore, the horizontal height of the first bottom wall 126 gradually decreases from the air inlet 124 towards the air outlet 104, and the horizontal height of the second bottom wall 127 gradually decreases from the air outlet 125 towards the air outlet 106. In this embodiment, the first bottom wall 126 at the bottom of the air inlet pipe 121 is inclined relative to the horizontal plane, and the horizontal height of the outlet end of the air inlet pipe 121 is lower. The second bottom wall 127 at the bottom of the air outlet pipe 122 is inclined relative to the horizontal plane, and the horizontal height of the inlet end of the air outlet pipe 122 is lower. Therefore, when the humidification component is tilted or overturned and then reset to its original position, the water in the air intake passage 1051 and air intake chamber 1052 flows smoothly back to the liquid storage chamber 101 through the first bottom wall 126, or the water in the air outlet passage 1071 and air outlet chamber 1072 flows smoothly back to the liquid storage chamber 101 through the second bottom wall 127, thus preventing water accumulation in the air intake and air outlet passages and providing two layers of protection for the backflow prevention function of the humidification component.

[0053] Furthermore, the axis of the air inlet 124 is set at a certain angle to the axis of the air inlet 104. In this embodiment, as shown... Figure 2 The airflow direction from the air inlet 124 into the air intake passage 1051 is parallel to the axis of the air inlet 124, and the airflow direction from the air inlet 104 out of the air intake passage 1051 is parallel to the axis of the air inlet 104. Therefore, the airflow directions into and out of the air intake passage 1051 are different, meaning the gas flow changes direction after passing through the air intake passage 1051. Consequently, the airflow velocity from the air inlet 102 into the liquid storage chamber 101 is weakened by the air intake passage 1051 after passing through it, increasing the gas humidification time and reducing the noise generated by high-speed gas flow.

[0054] Moreover, when the humidification unit is tilted or overturned, the liquid in the liquid storage chamber 101 is less likely to flow out from the air inlet channel, thereby preventing the liquid in the liquid storage chamber 101 from flowing to the fan assembly or mask, thus realizing the backflow prevention function of the humidification unit.

[0055] Furthermore, the axis of the air outlet 125 is set at a certain angle to the axis of the air outlet 106. In this embodiment, as shown... Figure 3 The airflow direction from the air outlet 106 into the air outlet passage 1071 is parallel to the axis of the air outlet 106, and the airflow direction from the air outlet 125 out of the air outlet passage 1071 is parallel to the axis of the air outlet 125. Therefore, the airflow directions into and out of the air outlet passage 1071 are different, meaning the gas flow changes direction after passing through the air outlet passage 1071. Consequently, the airflow velocity from the air outlet 106 out of the liquid storage chamber 101 is weakened by the air outlet passage 1071 after passing through it, increasing the humidification time of the gas and reducing the noise generated by the high-speed gas flow.

[0056] Moreover, when the humidification unit is tilted or overturned, the liquid in the liquid storage chamber 101 is less likely to flow out from the air outlet, thereby preventing the liquid in the liquid storage chamber 101 from flowing to the fan assembly or mask, thus realizing the anti-backflow function of the humidification unit.

[0057] Reference Figure 6 and Figure 7 As shown, specifically, the housing 10 also includes an air inlet pipe 13 connected to the upper housing 11 and connected to the air inlet 102, and an air outlet pipe 14 connected to the upper housing 11 and connected to the air outlet 103. In this embodiment, the humidification component is connected to the exhaust port of the fan component through the air inlet pipe 13, and to the air inlet of the breathing mask through the air outlet pipe 14.

[0058] Furthermore, the axis of the air inlet pipe 13 is set at a certain angle to the axis of the air inlet 102. In this embodiment, the axis of the air inlet pipe 13 is preferably inclined relative to the horizontal plane, and the horizontal height of the inlet of the air inlet pipe 13 is lower than the horizontal height of the outlet of the air inlet pipe 13. Therefore, when the humidification component is tilted or overturned, the liquid in the liquid storage chamber 101 is less likely to flow out from the air inlet pipe 13, thereby preventing the liquid in the liquid storage chamber 101 from flowing to the fan assembly or the mask, and realizing the backflow prevention function of the humidification component.

[0059] Furthermore, the axis of the air outlet pipe 14 is set at a certain angle to the axis of the air outlet 103. In this embodiment, the axis of the air outlet pipe 14 is preferably inclined relative to the horizontal plane, and the horizontal height of the outlet of the air outlet pipe 14 is lower than the horizontal height of the inlet of the air outlet pipe 14. Therefore, when the humidification component is tilted or overturned, the liquid in the liquid storage chamber 101 is less likely to flow out from the air outlet pipe 14, thereby preventing the liquid in the liquid storage chamber 101 from flowing to the fan assembly or the mask, and realizing the backflow prevention function of the humidification component.

[0060] Specifically, the humidification assembly further includes a sealing element 20, the flow guide shell 12 is snap-fitted to the upper shell 11, and the sealing element 20 connects to the flow guide shell 12 and abuts against the upper shell 11. In this embodiment, as... Figure 5 The guide shell 12 also includes a mounting plate 123 connecting the air inlet pipe 121 and the air outlet pipe 122. The mounting plate 123 is snap-fitted to the upper shell 11. The air inlet chamber 1052 and the air outlet chamber 1072 are formed between the upper shell 11 and the mounting plate 123. The sealing element 20 is made of elastic material and is sleeved on the edge of the guide shell 12, that is, on the edge of the mounting plate 123. When the guide shell 12 is snap-fitted to the upper shell 11, the sealing element 20 abuts against the guide shell 12 and the upper shell 11, eliminating the gap between the guide shell 12 and the upper shell 11, and ensuring the sealing of the air inlet chamber 1052 and the air outlet chamber 1072.

[0061] Specifically, the housing 10 also includes a lower housing 15 connected to the upper housing 11. In this embodiment, the upper housing 11 and the lower housing 15 are pivotally connected. Figure 4 After the upper shell 11 is pivoted open, liquid can be added to the liquid storage chamber 101.

[0062] Furthermore, the humidification assembly also includes a protective member 30 connected to the lower shell 15, with the upper shell 11 abutting against the protective member 30. In this embodiment, the protective member 30 is made of an elastic material, such as silicone, which can play a role in noise reduction, vibration damping, and sealing. The protective member 30 is sleeved on the lower shell 15. When the upper shell 11 is pivotally closed, the upper shell 11 abuts against the protective member 30, thereby ensuring the sealing of the liquid storage chamber 101. After the protective member 30 and the lower shell 15 are fixed together, the sealing strip 31 of the protective member 30 protrudes from the upper edge of the lower shell 15, and the upper shell 11 presses against the sealing strip 31.

[0063] Reference Figure 8 As shown, the humidification assembly further includes a heat-conducting plate 40 connected to the lower shell and a heating element (not shown) in contact with the heat-conducting plate 40. The shell 10 also has a mounting cavity 108, which is located on both sides of the heat-conducting plate 40 with the liquid storage cavity 101. In this embodiment, the heat-conducting plate 40 transfers the heat generated by the heating element to the liquid in the liquid storage cavity 101, thereby causing the liquid to evaporate, enabling simultaneous humidification and heating of the gas to be humidified.

[0064] Continue to cooperate with reference Figure 7 and Figure 8 As shown, specifically, the lower shell 15 has a first shell 151 forming an installation cavity 108 and a second shell 152 connecting the first shell 151. The humidification assembly also includes a latch 50 cooperating with the first shell 151, an unlocking member 60 cooperating with the latch 50, and an elastic member (not shown in the figure) abutting against the latch 50 and the unlocking member 60.

[0065] In this embodiment, the first shell 151 and the second shell 152 are fixed to each other, for example, by ultrasonic welding. A sealing gasket is provided between the heat-conducting plate 40 and the first shell 151, and the heat-conducting plate 40 is fixedly connected to the first shell 151 by a hot-melt column. A mounting post 153 is provided on the first shell 151, and the mounting post 153 is located in the mounting cavity 108. The latch 50 and the unlocking member 60 are both sleeved on the mounting post 153. The latch 50 can rotate relative to the mounting post 153, and the unlocking member 60 can move back and forth relative to the mounting post 153. An elastic member elastically abuts against the first shell 151 and the latch 50 in the back-and-forth direction, and the unlocking member 60 abuts against the latch 50. By pressing the unlocking member 60, the unlocking member 60 abuts against the latch 50 and drives the latch 50 to rotate around the mounting post 153, thereby unlocking the humidification component from the ventilator; after releasing the unlocking member 60, the latch 50 is reset by the action of the elastic member, and at the same time the latch 50 also resets the unlocking member 60, thereby locking the humidification component onto the ventilator.
