Description

Technical Field

[0001] The invention relates to the technical field of inhalers, in particular to an inhaler with metering and monitoring functions. Background Art

[0002] An inhaler is a medical device used to treat respiratory diseases, especially asthma, chronic obstructive pulmonary disease (COPD) and other diseases. Its main function is to convert drugs into aerosol or powder form so that they can directly enter the respiratory tract and achieve better therapeutic effects.

[0003] In order to facilitate users to know the remaining amount of medicine in real time, current inhalers are equipped with a metering mechanism inside the inhaler, such as the patent "Publication No. CN116507378A Medicament Inhaler and Counting Mechanism". However, in actual use of existing inhalers, users may easily forget to observe the metering number displayed on the shell due to other things, so that users occasionally forget to add medicine. At this time, if the user happens to be outdoors or in other places where it is inconvenient to take medicine, the user will inevitably fall into a situation where there is no medicine available; finally, current inhalers usually rely on the user to inhale to obtain medicine, but this often requires the user to inhale a large enough flow rate, otherwise a large amount of medicine will be wasted. Summary of the invention

[0004] The object of the present invention is to provide an inhaler with metering monitoring function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: an inhaler with metering and monitoring function, the inhaler comprises a shell, a cover sleeve and a straw, the cover sleeve is arranged on the upper part of the shell, a mounting frame is arranged inside the shell, a mounting plate, a storage plate, a fixing belt and a fixing seat are arranged on one side of the mounting frame, a first gear, a fourth gear, a ratchet mechanism and a metering mechanism are arranged on the other side of the mounting frame, the first gear is connected to the cover sleeve, the ratchet mechanism is connected to the storage plate, the fourth gear is connected to the mounting plate, the first gear is connected to the ratchet mechanism through the second gear, the fourth gear is connected to the metering mechanism through the third gear, one end of the fixing belt is connected to the mounting plate, the other end of the fixing belt is connected to the storage plate, a plurality of capsules are arranged on one end of the fixing belt located in the mounting plate, the fixing belt runs through the fixing seat, a crushing assembly and an air cavity are arranged in the fixing seat, and the straw is communicated with the air cavity.

[0006] Furthermore, the metering mechanism includes a metering disk, which is engraved with several metering numbers. A metering hole is provided on the outside of the shell, and the metering hole is aligned with one of the metering numbers. When the present invention is in use, the user only needs to open the cover to make the first gear rotate. When the first gear rotates, the storage disk is rotated through the second gear and the ratchet mechanism to facilitate the unused capsules on the fixed belt to move to the bottom of the crushing component. Then the user only needs to hold the straw in his mouth. When the crushing component crushes the capsule, the user can inhale the medicine in the capsule into the lungs by inhaling. When the storage disk rotates, the mounting disk will rotate synchronously with the fourth gear. At this time, the metering disk will rotate to a specific angle (the angle of rotation of the metering disk depends on the transmission ratio of the third gear and the fourth gear, and the transmission ratio can be freely designed according to actual needs) so that a certain metering number engraved on the metering disk is aligned with the metering hole. The user can judge the number of unused capsules by observing the value of the metering number aligned with the metering hole.

[0007] Furthermore, an early warning component is provided on one side of the mounting frame close to the metering disk, and the early warning component includes a support seat, an early warning plate and an early warning rod, the early warning rod is fixedly mounted on the outer end of the metering disk and aligned with one of the metering numbers, the early warning plate is movably mounted on the support seat through a rotating shaft, an arc groove is provided in the support seat, an arc spring rod is provided in the arc groove, and one end of the arc spring rod is fixedly mounted on the early warning plate. Compared with the metering mechanism currently provided in the inhaler, the present invention has an early warning function, that is, when the number of unused capsules reaches a set critical value, the user needs to exert greater force to open the cover sleeve, for example: the total number of capsules on the fixed belt is ten, and the early warning rod is aligned with the metering number "two" marked on the metering disk (the specific position of the early warning rod can be freely designed according to actual needs), then when the user opens the cover sleeve to use the second to last capsule, the early warning rod will contact the early warning plate, and at this time, compared with the previous use of the capsule, the user needs to spend more effort to open the cover sleeve. Through this technical solution, the present invention can remind the user that the capsule is about to be used up and needs to add capsules in time to prevent the user from encountering a situation where there is no medicine available.

[0008] Furthermore, a sealing assembly is also provided in the fixed seat, and the sealing assembly includes a lever, a sealing frame, a receiving groove and a second liquid storage tank. The sealing frame is arranged in the receiving groove, and the sealing frame and the receiving groove are connected by a first compression spring. A second piston and transmission fluid are arranged in the second liquid storage tank. One end of the lever is connected to the second piston, and the other end of the lever extends out of the outer shell. A fixing assembly is arranged on the outer side of one end of the lever close to the second piston.

[0009] Furthermore, the fixing component includes a block and a slot, and the block is movably installed in the slot by a second compression spring. A positioning block is arranged on the outside of one end of the lever close to the second piston. When the capsule is moved to the bottom of the crushing component of the present invention, the user needs to push the lever downward first. At this time, the lever will move downward with the second piston to squeeze the transmission fluid in the second liquid storage tank into the receiving tank. At the same time, the positioning block will pass through the block. Through the block and the positioning block, the lever will not be reset if the user does not continue to apply force to the lever. When the transmission fluid in the second liquid storage tank enters the receiving tank, under the action of hydraulic pressure, the sealing frame moves downward to form a closed space, ensuring that when the crushing component punctures the capsule, the medicine in the capsule will not splash around. Compared with the current inhaler, the present invention can reduce the risk of drug scattering and improve the efficiency of drug use.

[0010] Furthermore, a discharge channel is provided at one end of the air cavity close to the fixed belt, and the air cavity is connected with the straw through an exhaust channel. The crushing assembly includes a movable groove, a button, a transmission seat, a movable seat and a pricking needle. One end of the button extends out of the shell, and the other end of the button contacts the transmission seat. The ends of the button and the transmission seat that contact are both wedge-shaped structures. The movable seat is movably installed in the movable groove through a reset spring rod. The pricking needles are provided in several groups, and the several groups of pricking needles are all arranged at one end of the movable seat close to the fixed belt. A first push rod is provided at one end of the transmission seat close to the movable seat. To puncture the capsule according to the present invention, it is only necessary to press the button. When the button is pressed, the button will squeeze the transmission seat, thereby causing the transmission seat and the first push rod to move downward. The movable seat and the several groups of pricking needles are driven to move by the first push rod, and the capsule is punctured by the several groups of pricking needles. Compared with the current mechanism for puncturing capsules in inhalers, the present invention does not require multiple presses, thereby improving the use efficiency.

[0011] Furthermore, a first liquid storage tank, a hydraulic tank and a transmission spring rod are also provided in the fixed seat, a first piston and transmission fluid are provided in the first liquid storage tank, the transmission spring rod is provided in the hydraulic tank, the first piston is communicated with the hydraulic tank, a sealing plate is provided in the air cavity, the sealing plate is fixedly connected to one end of the transmission spring rod, a second push rod is provided at one end of the transmission seat close to the first piston, a gap is provided between the first push rod and the movable seat, when the button in the present invention is pressed, the transmission seat will go through two stages, the first stage: the transmission seat, the first push rod and the second push rod move downward, because there is a gap between the first push rod and the movable seat (the size of the gap can be freely designed according to needs), the second push rod will first push the first piston to move, under the action of the hydraulic pressure , the sealing plate and the transmission spring rod move down (the gas in the air cavity is discharged along the exhaust channel), the second stage: when the button is continued to be pressed, the movable seat will continue to move down, and finally the first push rod will contact the movable seat, and the movable seat and several groups of puncture needles will be driven to move by the first push rod, and the capsule will be punctured by several groups of puncture needles. When the capsule is punctured, the user needs to hold the straw and then release the transmission seat. Under the action of the reset spring rod and the transmission spring rod, the sealing plate and several groups of puncture needles will rise and reset. When the several groups of puncture needles are reset, the medicine in the capsule will be scattered into the sealing frame. When the sealing plate is reset, the medicine scattered into the sealing frame will be drawn into the air cavity, so as to facilitate the user to inhale the medicine into the lungs and prevent the user from having poor inhalation flow rate due to physical discomfort, so that the medicine is difficult to enter the user's lungs.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Compared with the current inhaler, the present invention is provided with an early warning component. When the number of unused capsules reaches a set critical value, the early warning component allows the user to spend more effort to open the cover. Compared with the current metering mechanism, the present invention can remind the user of the use of capsules according to the force used to open the cover, so that the user can add capsules in time and prevent the user from encountering a situation where there is no medicine available;

[0014] 2. The present invention is also provided with a sealing component. When the capsule moves to the bottom of the crushing component, the present invention can isolate the capsule from the external environment through the sealing component, forming a closed space to ensure that when the crushing component pierces the capsule, the medicine in the capsule will not splash around. Compared with the current inhaler, the present invention can reduce the risk of drug scattering and improve the use efficiency of the drug;

[0015] 3. When the button in the present invention is pressed, the transmission seat will go through two stages. In the first stage, the transmission seat, the first push rod and the second push rod move downward. Since there is a gap between the first push rod and the movable seat, the second push rod will drive the sealing plate and the transmission spring rod to move downward, thereby discharging the gas in the air cavity. In the second stage, the first push rod contacts the movable seat, and the movable seat and several groups of puncture needles are driven to move by the first push rod, and the capsules are punctured by the several groups of puncture needles, thereby eliminating the need to press the button multiple times to improve the use efficiency. After the capsule is punctured, the user needs to hold the straw and then release the transmission seat. Under the action of the reset spring rod and the transmission spring rod, the sealing plate and several groups of puncture needles will rise and reset. When the several groups of puncture needles are reset, the medicine in the capsule will be scattered into the sealing frame. When the sealing plate is reset, the medicine scattered into the sealing frame will be drawn into the air cavity, so as to facilitate the user to inhale the medicine into the lungs, thereby preventing the user from having poor inhalation flow rate due to physical discomfort, so that the medicine is difficult to enter the user's lungs.

A plurality of capsules are arranged at one end of the fixing belt 14 located in the mounting disk 12, the fixing belt 14 runs through the fixing seat 6, a crushing assembly and an air cavity 64 are arranged in the fixing seat 6, and the straw 5 is communicated with the air cavity 64.

[0029] like Figure 1-Figure 5 As shown, the metering mechanism includes a metering disk 157 on which a plurality of metering numbers are engraved, and a metering hole 11 is provided on the outside of the housing 1, and the metering hole 11 is aligned with one of the metering numbers.

[0030] like Figure 1-Figure 5As shown, an early warning component is provided on one side of the mounting frame 15 close to the metering disk 157, and the early warning component includes a support seat 155, an early warning plate 1551 and an early warning rod 1571, the early warning rod 1571 is fixedly mounted on the outer end of the metering disk 157 and aligned with one of the metering numbers, the early warning plate 1551 is movably mounted on the support seat 155 through a rotating shaft, an arc groove is provided in the support seat 155, an arc spring rod is provided in the arc groove, and one end of the arc spring rod is fixedly mounted on the early warning plate 1551.

[0031] When the present invention is in use, the user only needs to open the cover 2 to rotate the first gear 151. When the first gear 151 rotates, the second gear 152 and the ratchet mechanism 156 rotate the storage tray 13 to facilitate the unused capsules on the fixing belt 14 to move to the bottom of the crushing assembly. Then the user only needs to hold the straw 5 in his mouth. When the crushing assembly crushes the capsule, the user can inhale the medicine in the capsule into the lungs by inhaling. When the storage tray 13 rotates, the mounting tray 12 will rotate synchronously with the fourth gear 154. At this time, the metering disk 157 will rotate to a specific angle (the rotation angle of the metering disk 157 depends on the transmission ratio of the third gear 153 and the fourth gear 154, and the transmission ratio can be freely designed according to actual needs) so that a certain metering number marked on the metering disk 157 is aligned with the metering hole 11. The user can observe the metering hole 11. 1 can determine the number of unused capsules. Finally, compared with the metering mechanism currently provided in the inhaler, the present invention has an early warning function, that is, when the number of unused capsules reaches the set critical value, the user needs greater force to open the cover 2. For example, the total number of capsules on the fixing belt 14 is ten, and the early warning rod 1571 is aligned with the metering number "two" marked on the metering disk 157 (the specific position of the early warning rod 1571 can be freely designed according to actual needs). When the user opens the cover 2 to use the second to last capsule, the early warning rod 1571 will contact the early warning plate 1551. At this time, compared with the previous use of the capsule, the user needs to spend more effort to open the cover 2. Through this technical solution, the present invention can remind the user that the capsule is about to be used up and needs to add capsules in time to prevent the user from encountering a situation where there is no medicine available.

[0032] like Figure 2 , Figure 4-Figure 9 As shown, a sealing assembly is also provided in the fixing seat 6, and the sealing assembly includes a shifting rod 4, a sealing frame 65, a receiving groove 67 and a second liquid storage tank 68. The sealing frame 65 is arranged in the receiving groove 67, and the sealing frame 65 and the receiving groove 67 are connected by a first compression spring. A second piston 681 and a transmission fluid are provided in the second liquid storage tank 68. One end of the shifting rod 4 is connected to the second piston 681, and the other end of the shifting rod 4 extends out of the housing 1. A fixing assembly is provided on the outer side of one end of the shifting rod 4 close to the second piston 681.

[0033] like Figure 7 As shown, the fixing assembly includes a clamping block 69 and a clamping slot. The clamping block 69 is movably installed in the clamping slot through a second compression spring. A positioning block 41 is arranged outside one end of the shifting rod 4 close to the second piston 681 .

[0034] When moving the capsule to the bottom of the crushing assembly of the present invention, the user needs to push the lever 4 downward first. At this time, the lever 4 will move downward with the second piston 681, squeezing the transmission fluid in the second liquid storage tank 68 into the receiving tank 67. At the same time, the positioning block 41 will pass through the block 69. Through the block 69 and the positioning block 41, the lever 4 will not be reset without the user continuing to apply force to the lever 4. When the transmission fluid in the second liquid storage tank 68 enters the receiving tank 67, under the action of hydraulic pressure, the sealing frame 65 moves downward to form a closed space, ensuring that when the crushing assembly punctures the capsule, the medicine in the capsule will not splash around. Compared with the current inhaler, the present invention can reduce the risk of drug scattering and improve the efficiency of drug use.

[0035] like Figure 6 and Fig.10 As shown, a discharge channel 66 is provided at one end of the air cavity 64 close to the fixed belt 14, and the air cavity 64 is connected with the straw 5 through the exhaust channel. The crushing assembly includes a movable groove, a button 3, a transmission seat 61, a movable seat 62 and a needle 621. One end of the button 3 extends out of the housing 1, and the other end of the button 3 contacts the transmission seat 61. The contacting ends of the button 3 and the transmission seat 61 are both wedge-shaped structures. The movable seat 62 is movably installed in the movable groove through a return spring rod. The needle 621 is provided with a plurality of groups, and the plurality of groups of needles 621 are all arranged at one end of the movable seat 62 close to the fixed belt 14. A first push rod is provided at one end of the transmission seat 61 close to the movable seat 62.

[0036] like Figure 6 and Figure 8 As shown, a first liquid storage tank 63, a hydraulic tank and a transmission spring rod are also provided in the fixed seat 6, a first piston 631 and a transmission fluid are provided in the first liquid storage tank 63, the transmission spring rod is provided in the hydraulic tank, the first piston 631 is communicated with the hydraulic tank, a sealing plate is provided in the air cavity 64, the sealing plate is fixedly connected to one end of the transmission spring rod, a second push rod is provided at one end of the transmission seat 61 close to the first piston 631, and a gap is provided between the first push rod and the movable seat 62.

[0037] To puncture the capsule in the present invention, it is only necessary to press the button 3. When the button 3 is pressed, the button 3 will squeeze the transmission seat 61, thereby causing the transmission seat 61, the first push rod and the second push rod to move downward. Since there is a gap between the first push rod and the movable seat 62 (the size of the gap can be freely designed according to needs), the second push rod will first push the first piston 631 to move. Under the action of hydraulic pressure, the sealing plate and the transmission spring rod will move downward (the gas in the air cavity 64 will be discharged along the exhaust channel). When the button 3 is continued to be pressed, the movable seat 62 will continue to move downward. Finally, the first push rod will contact the movable seat 62, and the movable seat 62 and the plurality of groups of puncture needles 621 will be driven to move by the first push rod. The capsule is punctured by several groups of puncture needles 621. Compared with the current mechanism of puncturing the capsule of the inhaler, the present invention does not need to be pressed multiple times, thereby improving the use efficiency. When the capsule is punctured, the user needs to hold the straw 5 and then release the transmission seat 61. Under the action of the reset spring rod and the transmission spring rod, the sealing plate and the several groups of puncture needles 621 will rise and reset. When the several groups of puncture needles 621 are reset, the medicine in the capsule will be scattered into the sealing frame 65. When the sealing plate is reset, the medicine scattered into the sealing frame 65 will be drawn into the air cavity 64, so as to facilitate the user to inhale the medicine into the lungs and prevent the user from having poor inhalation flow rate due to physical discomfort, so that the medicine is difficult to enter the user's lungs.

[0038] Working principle of the present invention: When the present invention is in use, the user opens the cover 2 to rotate the storage tray 13, and the storage tray 13 moves the fixing belt 14 on the one hand, and rotates the installation tray 12 and the metering tray 157 on the other hand. When the metering tray 157 rotates, a certain metering number marked on the metering tray 157 will be aligned with the metering hole 11. The user can judge the number of unused capsules by observing the value of the metering number aligned with the metering hole 11. When the number of unused capsules reaches a set critical value, the user needs to have a greater force to open the cover 2 to remind the user that the capsules are about to be used up and that capsules need to be added in time. Finally, when the unused capsules on the fixing belt 14 move to the right below the several groups of needles 621, the user needs to push the lever 4 downward first, and at this time the sealing frame 65 moves downward to form a closed space to ensure that the several groups of needles 621 are in When the capsule is punctured, the medicine in the capsule will not splash around. Then the user only needs to press the button 3. At this time, the second push rod will first push the first piston 631 to move so that the gas in the air cavity 64 is discharged. When the button 3 is continued to be pressed, the first push rod will drive the movable seat 62 and the plurality of groups of puncture needles 621 to move, and the capsule is punctured by the plurality of groups of puncture needles 621. After the capsule is punctured, the user needs to hold the straw 5 and then release the transmission seat 61. Under the action of the reset spring rod and the transmission spring rod, the sealing plate and the plurality of groups of puncture needles 621 will rise and reset. When the plurality of groups of puncture needles 621 are reset, the medicine in the capsule will be scattered into the sealing frame 65. When the sealing plate is reset, the medicine scattered into the sealing frame 65 will be drawn into the air cavity 64, so as to facilitate the user to inhale the medicine into the lungs and prevent the user from having poor inhalation flow rate due to physical discomfort, so that the medicine is difficult to enter the user's lungs.
