Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a mist storage assembly and a nebulizer. BACKGROUND

[0002] In use, the nebulizer needs to convert the liquid medicine into aerosol. Before the air enters the mist storage assembly, it needs to be heated, and then the aerosol follows the air flow to be inhaled by the human body. In the related art, due to the aerosol cannot be inhaled in time and stored in the mist storage assembly, after the air enters the mist storage assembly and combines with the aerosol for a certain period of time, the heated air will be cooled to produce condensate water in the mist storage assembly, which will dilute the aerosol and change the gas flow path, thereby reducing the accuracy of the supplied liquid medicine concentration and the nebulization treatment effect, greatly weakening the delivery rate of the liquid medicine and wasting the use rate of the medicine. SUMMARY

[0027] The mist storage assembly of the first aspect embodiment and the atomizing device of the second aspect embodiment of the application will be described below with reference to the accompanying drawings. It should be noted that, for the purpose of description and understanding, in the embodiments of the present application, the downward direction is taken as the first direction, and the leftward direction is taken as the second direction.

[0028] The mist storage assembly 100 provided by the first aspect embodiment of the application, as shown in Figures 1 to 3 The mist storage assembly 100 comprises a cartridge body 110 and a liquid storage member 120.

[0029] The interior of the cartridge body 110 defines a mist storage cavity 112, an air inlet passage 113 and a liquid outlet passage 118. The mist storage cavity 112 is a chamber for storing aerosol, the air inlet passage 113 and the liquid outlet passage 118 are both in communication with the mist storage cavity 112, and the air inlet passage 113 and the liquid outlet passage 118 are arranged on the two sides of the cartridge body 110 along the upward and downward direction, the air inlet passage 113 is adapted to guide the aerosol into the cartridge body 110, and the liquid outlet passage 118 is adapted to discharge the condensed water in the mist storage cavity 112. Meanwhile, the cartridge body 110 further comprises a first passage 114 and a second passage 115, the first passage 114 and the second passage 115 are both in communication with the mist storage cavity 112, and the first passage 114 and the second passage 115 are distributed on the two sides of the cartridge body 110 along the leftward and rightward direction, the first passage 114 is adapted to guide the air into the cartridge body 110, and the second passage 115 is adapted to guide the aerosol out of the cartridge body 110.

[0030] The liquid storage member 120 comprises a liquid storage cup 121 and a valve core 122, the interior of the liquid storage cup 121 defines a liquid storage cavity 1211, the liquid storage cavity 1211 is a chamber for storing the condensed water, the liquid storage cup 121 is provided with a protruding portion 1212 along the upward and downward direction, and the protruding portion 1212 is protrudingly arranged towards the cartridge body 110. The valve core 122 is arranged in the liquid outlet passage 118. The liquid storage cup 121 is detachably connected to the cartridge body 110, so that the liquid outlet passage 118 has an open state and a closed state. In this embodiment, as shown in Figure 4 and Figure 5As shown, the protrusion 1212 is located on the side of the liquid storage cup 121 away from the container body 110 in the vertical direction, that is, on the lower side of the liquid storage cup 121. The protrusion 1212 is disposed inside the liquid storage cavity 1211. In another embodiment (not shown in the figure), the protrusion 1212 is located on the side of the liquid storage cup 121 facing the container body 110 in the vertical direction, and the protrusion 1212 is located on the outside of the liquid storage cavity 1211.

[0031] Among them, see Figure 4 As shown, when the liquid outlet channel 118 is open, the liquid storage cup 121 is connected to the side of the chamber 110 where the liquid outlet channel 118 is located. The protrusion 1212 abuts against the valve core 122, causing the valve core 122 to rise relative to the chamber 110. At this time, the valve core 122 and the inner wall of the liquid outlet channel 118 are spaced apart, so that the liquid storage chamber 1211 and the liquid outlet channel 118 are connected. (See reference...) Figure 3 As shown, when the liquid outlet channel 118 is closed, the liquid storage cup 121 is separated from the chamber 110, and the protrusion 1212 is also separated from the valve core 122. The valve core 122 will descend relative to the chamber 110 under its own weight. At this time, the outer wall of the valve core 122 and the inner wall of the liquid outlet channel 118 will abut against each other.

[0032] Specifically, in one example, the air inlet channel 113 is located on the upper side of the chamber 110, and the liquid outlet channel 118 is located on the lower side of the chamber 110. When the aerosol is introduced through the air inlet channel 113 and the air is introduced through the first channel 114, the chamber 110 is connected to the liquid storage cup 121 to open the liquid outlet channel 118. If the aerosol and air combine to produce condensate, the condensate will flow along the wall of the liquid storage cup 121 and enter the liquid storage chamber 1211 through the liquid outlet channel 118. In this embodiment, since the first channel 114 is located on the left side of the chamber 110 and the second channel 115 is located on the right side of the chamber 110, and the air flows from left to right, the aerosol will flow towards the second channel 115 under the influence of the air and will not enter the liquid storage chamber 1211 with the condensate. This achieves the separation of condensate and aerosol and also prevents condensate from accumulating in the mist storage chamber 112.

[0033] In related technologies, when condensation occurs within the mist storage chamber, the condensate cannot be drained in time, leading to its accumulation. This accumulated condensate dilutes the aerosol, resulting in inaccurate drug concentration and dosage. Furthermore, when the patient inhales the aerosol, the condensate alters the gas flow path, increasing aerosol flow resistance. The accumulated condensate may also clog the micropores of the mist storage component, affecting nebulization efficiency and even damaging the nebulizer. In addition, the accumulated condensate can foster microbial growth, increasing the risk of respiratory infections in patients.

[0034] Compared with the related art, the mist storage assembly 100 of the embodiment of the present application is detachably connected with the cartridge body 110 through the liquid storage cup 121, so that the protruding portion 1212 can be separated from the valve core 122 or abut against each other to open or close the liquid outlet passage 118. When the liquid storage cup 121 is connected with the cartridge body 110, the protruding portion 1212 abuts against the valve core 122 to lift the valve core 122 upward, so that the liquid outlet passage 118 and the liquid storage cavity 1211 are communicated, thereby causing the condensed water in the liquid storage cup 121 to flow into the liquid storage cavity 1211 for storage, so as to avoid the problem that the aerosol is diluted due to the accumulation of condensed water. Meanwhile, when the mist storage assembly 100 is completed to be used or the liquid storage cup 121 is replaced, after the liquid storage cup 121 is separated from the cartridge body 110, the valve core 122 falls relative to the cartridge body 110 to abut against the inner wall of the liquid outlet passage 118, thereby closing the liquid outlet passage 118, so as to avoid the leakage of condensed water or aerosol.

[0035] In some embodiments, referring to Figure 3 As shown in the figure, the cartridge body 110 has an inclined structure 116, the first passage 114 and the second passage 115 are respectively located on two sides of the liquid outlet passage 118, and the side of the cartridge body 110 where the first passage 114 is located and the side of the cartridge body 110 where the second passage 115 is located are connected to the side of the cartridge body 110 where the liquid outlet passage 118 is provided through the inclined structure 116, so that the height of the side of the cartridge body 110 where the liquid outlet passage 118 is provided is lower than the height of the side of the cartridge body 110 where the first passage 114 is located and the side of the cartridge body 110 where the second passage 115 is located along the up-down direction. Through the inclined structure 116, the condensed water generated on the inner wall of the mist storage cavity 112 can flow along the inner surface of the inclined structure 116 to the liquid outlet passage 118 during use, and will not accumulate near the first passage 114 and the second passage 115, thereby improving the collection efficiency of the condensed water.

[0036] Moreover, when the liquid outlet passage 118 is opened, the valve core 122 is lifted along the up-down direction by the protruding portion 1212. In this embodiment, the end of the valve core 122 is spaced apart from the passage opening of the first passage 114 and the passage opening of the second passage 115 along the up-down direction, that is, the valve core 122 does not have corresponding parts relative to the first passage 114 and the second passage 115 along the left-right direction, so that the valve core 122 is lifted upward by the protruding portion 1212 of the liquid storage cup 121, and when the air flows into the mist storage cavity 112 from the first passage 114, the valve core 122 does not interfere with the air flow through the first passage 114 and the second passage 115, thereby maintaining the normal flow and distribution of the aerosol in the mist storage cavity 112, thereby improving the combination and flow efficiency of the gas and the aerosol.

[0037] It can be understood that, in one of the examples, referring to Figures 1 to 4As shown, the air inlet passage 113 is arranged obliquely relative to the up-down direction towards the left-right direction, i.e. the air inlet passage 113 is not arranged vertically or horizontally relative to the cartridge body 110, but is arranged obliquely relative to the cartridge body 110.

[0038] Specifically, the air inlet passage 113 has an included angle with the cartridge body 110, and the air inlet passage 113 is arranged obliquely towards the second passage 115. By arranging the air inlet passage 113 obliquely, the aerosol entering the mist storage cavity 112 forms a specific flow path, thereby avoiding the aerosol flowing towards the valve core 122 or the liquid storage cavity 1211 opening to cause aerosol leakage. Moreover, the air inlet passage 113 is arranged obliquely towards the second passage 115, so that when the aerosol and air enter the mist storage cavity 112 at the same time, the aerosol and air do not produce relative impact to cause flow interference. On the contrary, when the aerosol enters the mist storage cavity 112, it will flow towards the second passage 115 under the action of inertia, at which time the flow direction of the aerosol is the same as that of the air, thereby improving the flow speed of the aerosol and air and promoting the atomization effect.

[0039] In some embodiments, referring to Figures 2 to 4 As shown, the cartridge body 110 includes a mist storage cartridge 111 and a fixing frame 117, the fixing frame 117 is connected to the bottom of the mist storage cartridge 111 along the up-down direction, the inside of the mist storage cartridge 111 defines a mist storage cavity 112, and the fixing frame 117 is arranged outside the mist storage cavity 112. The fixing frame 117 defines a liquid outlet passage 118. The passage wall of the fixing frame 117 has a first inclined portion 1172, which is a passage wall structure of the fixing frame 117. The outer wall of the valve core 122 has a second inclined portion 1221, which is an outer wall structure of the valve core 122. When the liquid outlet passage 118 is in a closed state, the first inclined portion 1172 and the second inclined portion 1221 abut each other to close the liquid outlet passage 118. When the liquid outlet passage 118 is in an open state, the first inclined portion 1172 and the second inclined portion 1221 are arranged spaced apart along the left-right direction to make the liquid storage cavity 1211 and the mist storage cavity 112 communicate through the liquid outlet passage 118.

[0040] Specifically, in one example, the bottom of the mist storage bin 111 is provided with an opening, and when the fixed frame 117 is connected to the mist storage bin 111, the liquid outlet channel 118 will be connected to the mist storage cavity 112 through the opening. When the condensed water is generated in the mist storage cavity 112, the condensed water will enter the liquid outlet channel 118 through the opening. By arranging the first inclined portion 1172, the cross-sectional area of the liquid outlet channel 118 can be gradually reduced in the direction from top to bottom, so that the fixed frame 117 has a funnel-shaped structure, thereby improving the flow speed of the condensed water in the liquid outlet channel 118, and thus promoting the collection efficiency of the condensed water. In the case where the bin body 110 has an inclined structure 116, the inclined structure 116 is arranged on the mist storage bin 111, and when the mist storage bin 111 and the fixed frame 117 are connected, the inclined structure 116 and the first inclined portion 1172 are connected, that is, after the condensed water flows to the liquid outlet channel 118 through the inclined structure 116, the condensed water will flow to the first inclined portion 1172 and then flow to the liquid storage cavity 1211 through the first inclined portion 1172.

[0041] Moreover, abutting the first inclined portion 1172 and the second inclined portion 1221 to seal the liquid outlet channel 118 can improve the sealing performance of the valve core 122 to the liquid outlet channel 118. Moreover, by using the first inclined portion 1172 and the second inclined portion 1221, the valve core 122 can be limited, and the valve core 122 will be limited by the gradually reduced structure of the liquid outlet channel 118, thereby avoiding the case that the valve core 122 moves to the outside of the liquid outlet channel 118 under the action of gravity, thereby improving the connection stability of the valve core 122 and the fixed frame 117.

[0042] Further, in some embodiments, referring to Figures 2 to 4 As shown, the liquid storage member 120 further includes an elastic member 123, and the two ends of the elastic member 123 in the up-down direction are respectively connected to the fixed frame 117 and the valve core 122, that is, one end of the elastic member 123 is connected to the fixed frame 117, and the other end is connected to the valve core 122. When the liquid outlet channel 118 is in an open state, the elastic member 123 will be pressed in the up-down direction by the fixed frame 117 and the valve core 122.

[0043] In the embodiment, when the valve core 122 is abutted by the protrusion 1212 to lift and open the liquid outlet passage 118, the valve core 122 will compress the elastic member 123 upwardly, and at this time the elastic member 123 will apply a counterforce to the valve core 122 in the downward direction. When the liquid storage cup 121 is detached from the liquid storage tank 111 to separate the protrusion 1212 and the valve core 122, the valve core 122 will lose the support force of the protrusion 1212, and at this time the valve core 122 will move in the downward direction under the action of the elastic member 123 to return to the closed state. The elastic member 123 can improve the moving speed of the valve core 122, thereby improving the switching efficiency of the liquid outlet passage 118. In this embodiment, in the closed state, the elastic member 123 can still be compressed in the up-down direction between the fixed frame 117 and the valve core 122, so that the elastic member 123 always applies a downward pressure to the valve core 122, thereby improving the sealing performance of the valve core 122 to the liquid outlet passage 118. In other embodiments, in the closed state, the elastic member 123 can also return to the original state.

[0044] Further, in one example, as shown in Figures 2 to 4 , and Figure 7 , the end of the valve core 122 has an abutting portion 1222, and the side of the fixed frame 117 away from the liquid storage tank 111 has a connecting portion 1171 extending in the up-down direction and towards the abutting portion 1222. When the elastic member 123 is connected to the valve core 122 and the fixed frame 117, one end of the elastic member 123 is sleeved on the outer periphery of the connecting portion 1171, and the other end is abutted against the abutting portion 1222.

[0045] Specifically, the elastic member 123 has a hollow structure. When the elastic member 123 is connected to the valve core 122 and the fixed frame 117, the elastic member 123 is sleeved on the peripheral wall of the connecting portion 1171 so that the connecting portion 1171 is arranged in the hollow structure. When the liquid outlet passage 118 is switched from the closed state to the open state, the elastic member 123 will be squeezed upwardly by the valve core 122, and the pressure generated by the elastic potential energy of the elastic member 123 will be applied to the fixed frame 117. Therefore, by arranging the connecting portion 1171 in the hollow structure, the connecting portion 1171 can limit the displacement of the elastic member 123 in the circumferential direction when the elastic member 123 applies pressure to the fixed frame 117, thereby improving the stability of the elastic member 123. Meanwhile, when the liquid outlet passage 118 is switched from the open state to the closed state, the pressure of the elastic member 123 will be applied to the valve core 122 to drive the valve core 122 to move relative to the fixed frame 117. By arranging the abutting portion 1222, the connection stability of the elastic member 123 and the valve core 122 can be improved, and the elastic force of the elastic member 123 can be applied to the fixed position of the elastic member 123, thereby improving the moving efficiency of the valve core 122 and promoting the switching speed of the liquid outlet passage 118.

[0046] It can be understood that, referring to Figure 6 As shown in the drawings, in one embodiment, the abutting portion 1222 comprises at least two abutting positions 1223. Among them, the number of abutting positions 1223 can be two, three, or four, etc. At least two abutting positions 1223 are arranged at intervals around the outer peripheral wall of the valve core 122. When the elastic member 123 is connected to the valve core 122, one end of the elastic member 123 abuts at least two abutting positions 1223. Among them, by arranging at least two abutting positions 1223 at intervals, a distributed support structure can be formed between the abutting positions 1223. The abutting positions 1223 can respectively disperse the force of the elastic member 123, avoid the situation of pressure concentration of the abutting portion 1222, thereby prolonging the service life of the valve core 122.

[0047] Specifically, in one example, the number of abutting positions 1223 is four. Four abutting positions 1223 are arranged at intervals around the outer peripheral wall of the end of the valve core 122 away from the fixed frame 117. Four abutting positions 1223 are arranged in the direction of the axis away from the valve core 122. When the elastic member 123 is connected to the valve core 122, the elastic member 123 abuts on the four abutting positions 1223. When discharging condensed water, after the condensed water flows out of the liquid outlet channel 118, the condensed water has the condition of flowing along the outer wall surface of the valve core 122. When the condensed water flows to the bottom end of the valve core 122, the interval arrangement of the abutting positions 1223 can make the condensed water have a flowing space, thereby improving the collection efficiency of the condensed water, and also avoiding too much condensed water accumulated at the end of the valve core 122 to cause damage to the valve core 122.

[0048] In another embodiment, referring to Figure 3 and Figure 4As shown, the elastic member 123 is arranged around the outer circumferential wall of the valve core 122, and the length dimension of the abutting portion 1222 in the left-right direction is smaller than the length dimension of the connecting portion 1171 in the left-right direction. Specifically, the shape structure of the valve core 122 is matched with the shape structure of the liquid outlet channel 118, the size of the valve core 122 gradually decreases in the direction from top to bottom, the elastic member 123 is arranged around the outer circumferential wall of the valve core 122 to improve the connection stability of the valve core 122 and the elastic member 123, and the elastic member 123 provides a limiting effect to the valve core 122 to prevent the valve core 122 from deviating in use, and the outer circumferential wall of the valve core 122 also provides a guiding effect to the elastic member 123 to ensure the activity stability of the elastic member 123. At the same time, the abutting portion 1222 has a first length L1 in the left-right direction, and the connecting portion 1171 has a second length L2 in the left-right direction, wherein the first length L1 is smaller than the second length L2. When the elastic member 123 is connected to the fixed frame 117 and the valve core 122, the elastic member 123 abuts against the abutting portion 1222 and the connecting portion 1171, so that the elastic member 123 is formed in a tapered spiral shape, thereby improving the stress uniformity of the elastic member 123 and avoiding local stress concentration of the elastic member 123.

[0049] In addition, when the liquid outlet channel 118 changes from the closed state to the open state, the valve core 122 needs to be lifted upward to compress the elastic member 123, at this time the force of the elastic member 123 is concentrated on the connecting portion 1171 of the fixed frame 117, by making the length of the connecting portion 1171 greater than that of the abutting portion 1222, the connection area of the elastic member 123 and the connecting portion 1171 can be increased, thereby improving the compression stability of the elastic member 123 and the opening stability of the liquid outlet channel 118.

[0050] In one example, referring to Figure 4 As shown, the liquid storage cup 121 has a planar portion 1213 on the side away from the cartridge body 110 in the up-down direction, i.e., the bottom of the liquid storage cup 121 is a planar structure. Specifically, the planar portion 1213 of the liquid storage cup 121 provides a support surface for the liquid storage cup 121, when the mist storage assembly 100 is in use, the mist storage assembly 100 needs to be placed for use by the patient, at this time the mist storage assembly 100 can be placed through the planar portion 1213, thereby avoiding the case that the mist storage assembly 100 is accidentally knocked over to cause aerosol leakage.

[0051] In another embodiment, the mist storage assembly 100 further comprises a liquid absorbing cotton, which is arranged in the liquid storage cavity 1211 of the liquid storage cup 121. The liquid absorbing cotton is used to absorb the condensed water flowing into the liquid storage cup 121, thereby increasing the amount of liquid that can be stored in the liquid storage cup 121.

[0052] Specifically, the liquid-absorbing cotton is exemplarily described as medical polyvinyl alcohol (PVA) cotton, which is contained in the liquid storage cavity 1211. When the condensed water enters the liquid storage cavity 1211, the condensed water is absorbed by the liquid-absorbing cotton. When the liquid-absorbing cotton reaches a saturated state, the condensed water is collected by the cup body space of the liquid storage cup 121, so that the content of the condensed water that can be collected by the liquid storage cup 121 is increased without increasing the volume of the liquid storage cup 121. When the liquid storage cup 121 is full of the condensed water, the continuous collection of the condensed water can be realized by replacing another liquid storage cup 121 with liquid-absorbing cotton, thereby saving the user's water pouring times and reducing the user's workload. In some embodiments, by replacing the liquid-absorbing cotton in the liquid storage cup 121, the continuous use of the liquid storage cup 121 can also be realized, and the reusability of the liquid storage cup 121 can be improved.

[0053] The second aspect of the present application provides an atomization device 10, as shown in Figures 1 to 8 The atomization device 10 includes an atomization assembly 200, an air tube assembly 300, and the liquid storage assembly 100 described in any of the above embodiments. The atomization assembly 200 includes a medicine cup 210 and an atomizer 220 connected to each other. The atomizer 220 converts the liquid medicine in the medicine cup 210 into aerosol, so that the aerosol enters the liquid storage cavity 112 through the air inlet channel 113 for use by the patient. The air tube assembly 300 includes an air inlet tube 310 and an air outlet tube 320. The air inlet tube 310 is connected to the first channel 114 to introduce air into the liquid storage cavity 112. The air outlet tube 320 is connected to the second channel 115 to allow the user to inhale the aerosol in the liquid storage cavity 112 for atomization treatment.

[0054] Specifically, in one example, the atomizer 220 is a vibrator. The atomizer 220 vibrates by piezoelectric ceramic to make the liquid medicine pass through the microporous mesh cover to form aerosol. In other embodiments, the atomizer 220 can also atomize the liquid medicine to form aerosol by heating. When the atomization device 10 is working, the atomizer 220 converts the liquid medicine into aerosol, which is then introduced into the liquid storage cavity 112 from the air inlet channel 113. At the same time, the first channel 114 also introduces air to combine with the aerosol to be inhaled by the patient from the second channel 115. The heating wire is arranged in the pipeline to heat the air to maintain the delivery air at a suitable temperature and humidity to prevent the patient's airway from drying. If the heated air combines with the aerosol to produce condensed water, the condensed water is discharged to the liquid storage cavity 1211 through the liquid outlet channel 118 for storage, thereby avoiding the situation that the condensed water is inhaled by the patient and the condensed water accumulates, thereby improving the atomization treatment effect of the atomization device 10.

[0055] The atomizing device 10 of the embodiment of the present application opens and closes the liquid outlet channel by the valve core 122, so that the condensed water can flow from the mist storage cavity 112 to the liquid storage cavity 1211 for storage, thereby avoiding the situation that the condensed water accumulates in the mist storage cavity 112 to dilute the aerosol and change the gas flow path, thus improving the accuracy of the supplied drug liquid concentration and the atomization treatment effect.

[0056] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
