Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an asthma inhaler device that facilitates control of drug dosage. Background Technology

[0002] Asthma is a common and frequently occurring respiratory disease, affecting people from children to those over 60. Essentially, asthma is a chronic airway inflammation involving multiple cells in the body, primarily manifesting as wheezing, chest tightness, and coughing. These symptoms typically worsen at night or in the early morning and tend to lessen or even disappear during the day. Using asthma medications, such as bronchodilators, can completely relieve symptoms without side effects or impacting quality of life. Asthma inhalers are medical devices that convert asthma medication into a mist, allowing patients to inhale it into their trachea. These devices are primarily used to quickly control asthma attacks and relieve symptoms such as chest tightness. By actively inhaling the nebulized medication, patients can directly target the airways for rapid therapeutic effects.

[0003] Currently, there are various asthma inhaler devices available on the market, including oxygen-driven nebulizers and compressor nebulizers that are not easy to carry, as well as portable options such as salbutamol inhaler, Symbicort, imported tiotropium bromide powder inhaler, and domestic tiotropium bromide powder inhaler.

[0004] However, in actual use, existing asthma inhalers often lack the function of controlling the dosage, making it difficult for patients to accurately control the amount of medication inhaled each time. This can easily lead to overdosing or underdosing. Overdosing not only increases unnecessary financial burden but may also cause adverse reactions such as increased heart rate, tremors, and headaches. Underdosing may fail to effectively control asthma symptoms, leading to recurrence or worsening of the condition.

[0005] Therefore, there is an urgent need to improve this shortcoming. The present invention studies and improves the existing structure and its deficiencies, and provides an asthma inhaler device that facilitates the control of drug dosage. Summary of the Invention

[0006] The purpose of this invention is to provide an asthma inhaler that facilitates the control of drug dosage, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an asthma inhaler device for easy control of dosage, comprising a medication chamber and a transmission structure. The outer surface of the medication chamber is provided with equidistant anti-slip textures and a viewing window. A control box is fixedly connected to the top of the medication chamber, and a micro motor is fixedly installed inside the control box. The output shaft of the micro motor is fixedly connected to a stirring rod via a coupling, and a stirring blade is fixedly connected to the outer wall of the stirring rod. The transmission structure is located inside the control box, and a feed control assembly is located inside the control box. The feed control assembly includes a shell, a hose, and a compression block. The outer wall of the shell is welded to the inner wall of the control box. One end of the hose is fixedly connected to a liquid extraction pipe, which is connected in series with a micro pump. The other end of the hose is fixedly connected to a temporary storage chamber, and an nebulizer is fixedly connected to the outer wall of the temporary storage chamber. A dispensing nozzle is fixedly connected to the outlet of the nebulizer.

[0008] Furthermore, the number of stirring blades is eight, and four stirring blades form a group, with the two groups of stirring blades arranged symmetrically about the central axis of the stirring rod.

[0009] Furthermore, the transmission structure includes a vertical rod, a first bevel gear, and a driven gear. The bottom end of the vertical rod is movably connected to the top of the medicine chamber via a bearing, and the top end of the vertical rod is fixedly connected to the first bevel gear. The driven gear is welded to the outer wall of the vertical rod.

[0010] Furthermore, the transmission structure also includes a drive gear, which is sleeved on the stirring rod and meshes with the driven gear.

[0011] Furthermore, the stirring rod and the vertical rod are driven by a driving gear and a driven gear, and the rotational speed of the stirring rod is faster than that of the vertical rod.

[0012] Furthermore, the transmission structure also includes a transverse rod and a second bevel gear. The two ends of the transverse rod are movably connected to the inner wall of the control box through bearings, and the outer wall of the transverse rod is fixedly connected to the second bevel gear, which meshes with the first bevel gear.

[0013] Furthermore, the hose is disposed inside the housing, and both ends of the hose extend through the housing to the outside.

[0014] Furthermore, the extrusion block is disposed inside the outer casing, and the extrusion block is sleeved on the transverse rod, which penetrates the outer casing.

[0015] Furthermore, a pressure balancing assembly is fixedly connected to the top of the drug compartment, and the pressure balancing assembly includes a cover, a channel, a vent pipe, an annular frame, and a nitrogen bladder. The top of the cover has a channel, and the bottom of the cover is fixedly connected to a vent pipe. The annular frame is fixedly installed inside the cover, and the top of the cover is fixedly connected to a nitrogen bladder.

[0016] Furthermore, the top end of the vent pipe is connected to the bottom of the cover, and the bottom end of the vent pipe is connected to the top of the medicine compartment. The cover is also connected to the medicine compartment through the vent pipe.

[0017] This invention provides an asthma inhaler device that facilitates control of drug dosage, and has the following beneficial effects:

[0018] 1. This invention is equipped with a micro motor, which drives the stirring rod and stirring blade to rotate, stirring the medicine to prevent the precipitation of the active ingredients and help to control the dosage more accurately. A transmission structure is also included, allowing the vertical rod to rotate with the stirring rod, thereby driving the extrusion block to periodically extrude the tubing inside the outer shell. This ensures that the medicine enters the temporary storage chamber evenly and in equal amounts, achieving strict dosage control. This allows patients to accurately control the amount of medicine inhaled each time, avoiding overdose or underdose, thus helping to improve the treatment effect of asthma.

[0019] 2. This invention is equipped with a pressure balancing component. When the amount of medicine in the medicine chamber decreases, causing a decrease in its internal pressure, the nitrogen stored in the nitrogen bladder can enter the medicine chamber along the ventilation tube under the action of the pressure difference to balance the pressure difference. If the nitrogen in the nitrogen bladder is exhausted, outside air can also enter the cover through the slot at the top of the cover, causing the nitrogen bladder to collapse inward to balance the pressure difference. The improved asthma inhaler can not only maintain the pressure stability inside the medicine chamber and avoid negative pressure inside the medicine chamber due to the decrease of medicine, which helps the stability of the spraying operation of the inhaler, but also prevents the medicine from contacting the outside air and deteriorating faster, thus improving the effectiveness of the device.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] like Figures 1-5As shown, an asthma inhaler device for easy dosage control includes a medication chamber 1 and a transmission structure 8. The outer surface of the medication chamber 1 is provided with equidistant anti-slip textures 2, and a viewing window 3 is provided on the outer surface of the medication chamber 1. A control box 4 is fixedly connected to the top of the medication chamber 1, and a micro motor 5 is fixedly installed inside the control box 4. The output shaft of the micro motor 5 is fixedly connected to a stirring rod 6 via a coupling, and stirring blades 7 are fixedly connected to the outer wall of the stirring rod 6. There are eight stirring blades 7, and four stirring blades 7 form a group. Two groups of stirring blades 7 are symmetrically arranged about the central axis of the stirring rod 6. The transmission structure 8 is located inside the control box 4. The transmission structure 8 includes a vertical rod 801, a first bevel gear 802, and a driven gear 803. The bottom end of the vertical rod 801 is movably connected to the top of the medicine container 1 via a bearing, and the top end of the vertical rod 801 is fixedly connected to the first bevel gear 802. The driven gear 803 is welded to the outer wall of the vertical rod 801. The transmission structure 8 also includes a driving gear 804, which is sleeved on the stirring rod 6 and meshes with the driven gear 803. The stirring rod 6 and the vertical rod 801 are connected via the driving gear 803. 4. The stirring rod 6 meshes with the driven gear 803, and the rotational speed of the stirring rod 6 is faster than that of the vertical rod 801. The transmission structure 8 also includes a horizontal rod 805 and a second bevel gear 806. The two ends of the horizontal rod 805 are movably connected to the inner wall of the control box 4 through bearings, and the outer wall of the horizontal rod 805 is fixedly connected to the second bevel gear 806. The second bevel gear 806 meshes with the first bevel gear 802. The control box 4 is equipped with a material control assembly 9, which includes a housing 901, a hose 902, and an extrusion block 903. The outer wall of the housing 901 is connected to the control box 4. The inner walls are welded together. The hose 902 is located inside the outer shell 901, and both ends of the hose 902 extend through the outer shell 901 to its outside. The extrusion block 903 is located inside the outer shell 901, and the extrusion block 903 is sleeved on the transverse rod 805, and the transverse rod 805 extends through the outer shell 901. One end of the hose 902 is fixedly connected to the liquid extraction pipe 10, and the liquid extraction pipe 10 is connected in series with the micro pump body 11. The other end of the hose 902 is fixedly connected to the temporary storage chamber 12, and the outer wall of the temporary storage chamber 12 is fixedly connected to the nebulizer 13, and the mist outlet of the nebulizer 13 is fixedly connected to the drug dispensing nozzle 14.

[0029] The specific operation is as follows: When using, hold the medicine container 1 and place the dispensing nozzle 14 at the patient's breathing position. Start the micro motor 5, which drives the stirring rod 6 and stirring blade 7 to rotate, stirring the medicine to prevent the precipitation of the active ingredients and help to more accurately control the dosage. During this process, the stirring rod 6 is driven by the meshing of the driving gear 804 and the driven gear 803, which drives the vertical rod 801 to rotate. Then, the second bevel gear 806 meshes with the first bevel gear 802 to drive the horizontal rod 805 to rotate, thereby driving the squeezing block 903 to periodically squeeze the tubing 902 inside the outer shell 901. At the same time, the micro pump 11 is started to pump the medicine container. The medication is drawn from the tube 10 and enters the flexible tube 902. Under the compression control of the feeding component 9, the medication enters the temporary storage chamber 12 in an even and equal amount. It is then atomized by the nebulizer 13 and sprayed from the dispensing nozzle 14 onto the patient's breathing position until the medication dosage in the temporary storage chamber 12 reaches the target dosage. At this point, the micro motor 5 stops operating. Through the transmission structure 8, the feeding component 9 can be driven to operate while the medication is being evenly distributed, strictly controlling the dosage of medication entering the temporary storage chamber 12. With the combined use of the feeding component 9 and the stirring blade 7, the purpose of strictly controlling the dosage is achieved, allowing the patient to accurately grasp the amount of medication inhaled each time, avoiding overdose or underdose, thereby helping to improve the treatment effect of asthma.

[0030] like Figure 1 and Figure 6 As shown, the transmission structure 8 is located inside the control box 4, and the control box 4 contains a material control assembly 9. The material control assembly 9 includes a housing 901, a hose 902, and a squeezing block 903. One end of the hose 902 is fixedly connected to a liquid extraction pipe 10, and the liquid extraction pipe 10 is connected in series with a micro pump body 11. The other end of the hose 902 is fixedly connected to a temporary storage chamber 12, and an atomizer 13 is fixedly connected to the outer wall of the temporary storage chamber 12. A drug dispensing nozzle 14 is fixedly connected to the mist outlet of the atomizer 13. A pressure balancing assembly 15 is fixedly connected to the top of the drug chamber 1, and the pressure balancing assembly 15 includes a cover 1. 501, through groove 1502, vent pipe 1503, ring frame 1504 and nitrogen bladder 1505. The top of the cover 1501 is provided with through groove 1502, and the bottom of the cover 1501 is fixedly connected with vent pipe 1503. The ring frame 1504 is fixedly installed inside the cover 1501, and the top of the cover 1501 is fixedly connected with nitrogen bladder 1505. The top end of vent pipe 1503 is connected to the bottom of the cover 1501, and the bottom end of vent pipe 1503 is connected to the top of the medicine chamber 1. The cover 1501 is connected to the medicine chamber 1 through vent pipe 1503.

[0031] The specific operation is as follows: when the asthma medication in the medication chamber 1 is drawn out by the micro pump 11, it is sent to the control assembly 9 and the temporary storage chamber 12 along the extraction pipe 10. As the amount of medication in the medication chamber 1 decreases, the pressure in the medication chamber 1 decreases accordingly. This allows the nitrogen stored in the nitrogen bladder 1505 to enter the medication chamber 1 along the ventilation pipe 1503 under the action of the pressure difference, so as to balance the pressure difference. When the nitrogen in the nitrogen bladder 1505 is exhausted, outside air can enter the cover 1501 through the through groove 1502 on the top of the cover 1501, causing the nitrogen bladder 1505 to indent inward, which can also achieve the effect of balancing the pressure difference. Through the above design, not only can the pressure inside the medication chamber 1 be kept stable, avoiding negative pressure inside the medication chamber 1 due to the decrease of medication, which helps the stability of the spraying operation of the spraying device, but also the medication is prevented from contacting the outside air and deteriorating rapidly, thus improving the effect of the device.

[0032] In summary, combining Figures 1-6 As shown, the working principle of this asthma inhaler device, which facilitates dosage control, is as follows: First, hold the medication chamber 1 and place the dispensing nozzle 14 at the patient's breathing position. Then, start the micro motor 5, which drives the stirring rod 6 and stirring blade 7 to rotate, stirring the medication. During this process, the stirring rod 6 is driven by the meshing of the driving gear 804 and the driven gear 803, which drives the vertical rod 801 to rotate. Then, the second bevel gear 806 meshes with the first bevel gear 802, which drives the horizontal rod 805 to rotate. This causes the squeezing block 903 to periodically squeeze the hose 902 inside the outer shell 901. At the same time, the micro pump 11 is activated to draw the medication from the medication chamber 1, causing the medication to flow along the pump... The liquid tube 10 enters the hose 902 and, under the squeezing control of the feed control component 9, enters the temporary storage chamber 12 in a uniform and equal amount. It is then atomized by the nebulizer 13 and sprayed from the dispensing nozzle 14 towards the patient's breathing position until the dosage in the temporary storage chamber 12 reaches the target dosage. During the spraying process, as the dosage in the medication chamber 1 decreases, the pressure in the medication chamber 1 decreases accordingly. The nitrogen stored in the nitrogen bladder 1505 will enter the medication chamber 1 along the ventilation tube 1503 under the action of the pressure difference to balance the pressure difference. When the nitrogen in the nitrogen bladder 1505 is exhausted, outside air can enter the cover 1501 through the through groove 1502 at the top of the cover 1501, causing the nitrogen bladder 1505 to indent inward, which can also achieve the effect of balancing the pressure difference.
