Description

Technical Field

[0001] The invention relates to the field of medical atomizers, and in particular to a portable atomizing drug delivery device. Background Art

[0002] At present, the atomization inhalation treatment method on the market is an important and effective treatment method for respiratory diseases. The drug solution is atomized into tiny particles by a nebulizer, and the drug enters the respiratory tract and lungs by inhalation, thereby achieving the purpose of painless, rapid and effective treatment. With the development of atomization technology, various atomizer devices are becoming more and more intelligent and more expensive, and are generally not discarded after use. Intelligent atomization devices generally use related electronic objects such as batteries, circuit boards and other electronic components, which will inevitably lead to the generation of electronic waste and pollute the environment. Therefore, existing atomizer devices have a commonality. After a long time of use, even if the atomizer device is cleaned after use, a certain amount of drug solution will be precipitated, and the deterioration will remain in the atomizer device. If these residual drug solutions are repeated many times and used continuously for a long time, they will contaminate the new drug solution or produce another chemical reaction to the new drug solution, which is likely to cause other diseases to the patient and is not conducive to the patient's treatment. Summary of the invention

[0008] The first threaded tube is communicated with the second threaded tube.

[0009] A first-stage pressurization chamber is provided in the passage connecting the first inner core fixing tube in the first threaded tube and the second inner core fixing tube in the second threaded tube.

[0010] A secondary pressurizing chamber is provided in the inner space of the first inner core fixed tube above the first one-way valve;

[0012] A second sealing ring is provided between the first inner core fixing tube and the first threaded tube;

[0013] A third sealing ring is provided between the second inner core fixing tube and the second threaded tube;

[0014] A booster motion structure is provided between the atomizing assembly and the lower shell assembly inside the upper shell, which cooperates with the liquid guide tube to boost the liquid supply to the nozzle for atomization. The booster motion structure includes claw-shaped fasteners extending downwards on both sides of the bracket, connecting pieces extending upwards on the lower shell below the corresponding fastener positions on both sides, arc-shaped transition protrusions in contact with the fasteners on the ends of the connecting pieces on both sides, oblique grooves connected with the fastener snap-on on the connecting pieces below the arc-shaped transition protrusions, top blocks extending outwards to the outside of the fasteners are provided on the side surfaces of the connecting pieces between the inner walls of the upper shells on both sides, first inverted buckles are provided on the brackets corresponding to the positions of the top blocks on both sides, second inverted buckles corresponding to the first inverted buckles are provided on the lower shell below the first inverted buckles, reset springs are provided between the first and second inverted buckles on both sides, and a key mechanism surrounding the fasteners on both sides is provided between the fasteners at the top block position and the inner wall of the upper shell; the top block is provided on one side of the oblique groove. The button mechanism is connected to the top of the return springs on both sides, and then the top block on the top connecting piece of the return spring makes the fastener disengage from the inclined groove. Therefore, the first one-way valve and the second one-way valve have the functions of guiding liquid and preventing liquid backflow. In addition, high-density cotton, microporous parts, etc. can be used as substitutes. Of course, it can also be set to have only one position or multiple positions.

[0015] In some embodiments, the button mechanism includes a first outer shell and a second outer shell that are sleeved on the return springs on both sides, an elastic body that is integrally connected to the first outer shell and the second outer shell is provided between the first outer shell and the second outer shell, and a pressing block that extends to the outside of the upper shell is provided on the first outer shell and the second outer shell. The pressing block is provided at a position corresponding to one side of the top block after the fastener is inserted into the inclined groove.

[0016] In some embodiments, the elastic body is a wave-shaped spring sheet or an arc-shaped spring sheet.

[0017] In some embodiments, a fourth sealing ring is provided at the position where the catheter is inserted into the drug solution bottle.

[0018] In some embodiments, the fixing frames on both sides of the lower shell are respectively provided with protrusions that are in frictional contact with the inner wall of the upper shell. The protrusions play a certain role in frictional fit with the upper shell, but the friction effect is not too great to hinder the movable connection between the lower shell and the upper shell.

[0019] In some embodiments, in the initial state, the fastener is disengaged from the chute and the connector partially overlaps with the fastener. Pushing down the anti-slip pattern on the lower shell causes the upper shell assembly to slide downward until the fastener is inserted into the chute, at which point the lower shell assembly is locked by the fastener, the second one-way valve on the liquid guide tube is opened, the primary pressurizing chamber is in a near-vacuum state, and the air pressure in the liquid medicine bottle compresses the liquid medicine to enter the primary pressurizing chamber from the liquid guide tube.

[0020] In some embodiments, the length of the overlap between the connecting member and the fastener portion corresponds to the distance that the lower shell slides within the sliding groove.

[0021] In some embodiments, after the lower shell assembly is locked by the fastener, the pressing block pushes the top block through external force to disengage the fastener from the inclined groove. At this time, the lower shell assembly is unlocked, and the lower shell assembly slides upward and returns to its position under the action of the return spring. The second one-way valve is closed, and the medicine in the first-stage boosting chamber is pressed into the second-stage boosting chamber.

[0022] In some embodiments, after the liquid medicine in the secondary boosting chamber is full, it is compressed in the primary boosting chamber to spray out a liquid column, which is blocked by the nozzle with microporous mesh and is divided into an atomized state of small liquid particles.

[0023] The beneficial effects of the present invention are that it is easy to use, pollution-free and environmentally friendly. Since the overall atomization process is determined by whether there is a snap connection between the fastener on the bracket and the chute of the connecting piece on the lower shell. In the initial state, the fastener and the connecting piece overlap, and the fastener and the chute are detached. After pushing down, the fastener is snap-connected with the chute, and the liquid medicine is pressed into the primary booster chamber; after pushing up, the fastener is detached from the chute, moved up and overlapped, and the liquid medicine in the primary booster chamber is pressed into the secondary booster chamber until it is full, and so on, and finally the liquid medicine in the secondary booster chamber is sprayed out of the nozzle by atomization using pressure. The overall process is mainly to atomize the liquid medicine by mechanical physical principles, thereby achieving the purpose of atomization drug administration. In addition, the material of the quantitative liquid medicine bottle is used, which can be recycled and reused, and can be discarded after one use without secondary use pollution. In addition, no batteries and related electronic items are used as a whole, the cost is low, no electronic waste is generated, and it is energy-saving and environmentally friendly. The filter layer design is adopted to effectively filter the liquid medicine itself to a certain extent, which is safer and more effective. Therefore, it is easy to use, pollution-free and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] How it works

[0038] The overall structure is divided into three parts: an upper shell component 01, an atomizer component 02, and a lower shell component 03. The atomizer component 02 is fixed to the upper shell component 01, while the lower shell component 03 is movable.

[0039] like Figure 1As shown, when in use, push the anti-slip groove 36 downward, and the lower shell component 03 will move downward to the position shown in FIG. Figure 3 In the state shown, the second one-way valve 213 at the end of the liquid guide tube 212 is open, the first-stage boosting chamber 214 is in a near-vacuum state, and the air pressure in the liquid chamber compresses the liquid from the liquid guide tube 212 into the first-stage boosting chamber 214. At this time, the lower shell assembly 03 is locked. Then, press the pressing blocks 54 on both sides to push the top block 45 to urge the fastener 41 to disengage from the inclined groove 44, and then unlock. After unlocking, the lower shell assembly 03 rebounds under the action of the return spring 48, and the second one-way valve 213 at the end of the liquid guide tube 212 is closed, forming a piston-like mechanism, pressing the liquid from the first-stage boosting chamber 214 into the second-stage boosting chamber 215, and repeating this several times until the second-stage boosting chamber 215 is filled with liquid. At this time, according to the above steps, the liquid in the second-stage boosting chamber 215 is compressed by the liquid from the first-stage boosting chamber 214, and a liquid column is ejected. The liquid column is blocked by the microporous mesh on the nozzle 26 and is divided into small liquid particles, that is, atomized. Each operation is atomized once.

[0040] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the invention.
