Description

Compression atomizer

Technical Field

The application relates to a medical appliance, in particular to a suction type therapeutic instrument for treating respiratory diseases, such as cold, fever, cough, asthma, sore throat, rhinitis, chronic pharyngitis, tonsillitis, bronchitis and the like, in particular to a compression atomizer.

Background

Respiratory diseases such as cold, fever, cough, asthma, sore throat, rhinitis, chronic pharyngitis, tonsillitis, bronchitis, etc. are often treated using inhalation therapeutic devices, such as nebulizers. Compression atomizers and ultrasonic atomizers are two types of atomizers commonly used. The compression atomizer has the advantages of convenience, no pain, obvious curative effect, small side effect of the medicine and the like. The compressed atomizer atomizes the liquid containing the medicine by using an air compressor, and the atomized medicine is inhaled by a patient, easily goes deep into the positions of the lung and the branch capillary vessel by breathing, and is suitable for being directly absorbed by a human body.

CN 101060877 a discloses an inhaler, which utilizes compressed air to form high-speed airflow through a fine nozzle, and the generated negative pressure drives the liquid containing the medicine to be sprayed onto an obstacle, and splashed to the periphery under high-speed impact to form aerosol containing the medicine. The patient can mix the aerosol containing the medicine with the outside air through the suction inlet and inhale, and the excessive inhalation of the aerosol by the user can be prevented.

However, the above-mentioned inhaler has a nebulization generating region directly communicating with the inhalation port, so that the medicine scattered into the non-inhalation passage cannot be sufficiently absorbed and utilized. In addition, the interval between the atomization generating area and the suction inlet is lacked, the low-temperature atomized medicine and air are directly inhaled by a patient, the stimulation to the respiratory tract is easy to generate, the cough is easy to cause, and the cough airflow of the patient reversely enters the inhaler, so that the secondary pollution is easy to cause. Meanwhile, the existing atomizers have the problem of too many assembly parts, so that the unused medicines and bacteria-carrying parts inhaled by patients are difficult to be sufficiently cleaned. The atomizer is easy to introduce bacteria due to the fact that internal parts are multiple and difficult to disassemble and assemble, and the atomizer is required to be prevented from being directly contacted with hands in the process of disassembling, cleaning and assembling the internal parts in use, however, the problem of avoiding the bacterial contamination link is not emphasized in the industry, and the hidden instrument pollution problem is prominent.

Detailed Description

In order to more clearly understand the technical features, objects, and effects of the present application, embodiments of the present application will now be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

As described in the background, the present application provides a compressed atomizer, as shown in fig. 1, which shows a schematic structural view of a compressed atomizer according to an embodiment of the present application, and the compressed atomizer of the present application includes a compressor 10, an atomizing cup 20, and a hose 30 connecting a compressed air outlet 11 of the compressor 10 and a compressed air inlet 21 (shown in fig. 2 and 3) of the atomizing cup 20, wherein the compressor 10 delivers compressed air to the atomizing cup 20 via the hose 30.

Further, the present application is an improvement over the prior art primarily in the construction of the aerosolizing cup 20. Fig. 2 is an exploded perspective view showing an atomizing cup for a compression nebulizer according to an embodiment of the present application, and fig. 3 is an assembled structural view showing the atomizing cup for the compression nebulizer according to another embodiment of the present application. For convenience of explanation, a part of the structure in fig. 2 and 3 is processed in a partial sectional view.

Referring to fig. 2 and 3, the cup 20 for atomizing a medicine of the present application includes a medicine container 100, an atomizing core 200 disposed inside the medicine container 100, and a cap 300. Similar to the prior art cited in the background section, the bottom of the cartridge 100 of the present application is provided with a conical nozzle 101 communicated with the compressed air inlet 21, which can cooperate with the relevant structure of the atomizing core 200 to draw and spray the liquid medicine in the cartridge 100 through the ejection effect of the compressed air entering from the compressed air inlet 21. The fundamental operation principle of the present application is the same as the prior art cited in the background art, and the whole content is cited as reference, the relevant operation principle is not the invention point of the present application, and the present application can be understood by those skilled in the art by referring to the prior art, and the following part of the description relating to the operation principle will be briefly described.

Unlike the prior art, the bottom of the atomizing core 200 of the present application is integrally formed with a conical flow guide cap 201 which is turned over outside the conical nozzle 101, and the conical flow guide cap 201 is integrally formed between two arc-shaped arms 203 extending downward from a cylindrical side wall 202 of the atomizing core 200.

In the prior art, the conical draft shield associated with the conical nozzle is typically a separate component that is held within the cartridge. When disassembly and cleaning are needed, the independent components inside the medicine containing barrel need to be taken out of the medicine containing barrel by hands or tools, and after cleaning, the components need to be aligned with the conical nozzle to be assembled and restored, so that the disassembly is difficult on one hand, and the bacterial pollution is easily caused due to too many links of contact with the outside on the other hand. The cone-shaped drainage cover adopting an independent component in the prior art is formed by a plastic processing technology, namely, part of the structure of the cone-shaped drainage cover needs to be stretched into the cylindrical structure of the atomization core in the prior art, so that the cone-shaped drainage cover and the atomization core cannot be manufactured into an integral structure through an injection molding technology. And this application adopts two arc arms 203 that extend downwards from the cylindric lateral wall 202 of atomizing core 200, through two arc arms 203 centre gripping toper drainage cover 201 for the structure relevant with toper drainage cover 201 all is located outside the region that cylindric lateral wall 202 centers on, therefore is convenient for carry out disposable injection moulding through the form of moulding, has realized an organic whole structure through the structure of optimizing, has simplified processing, has avoided bacterial contamination.

Further, an atomization baffle 204 which generates an atomization effect corresponding to the conical flow guide cover 201 is also arranged between the two arc-shaped arms 203, as shown in fig. 4, which is an exploded schematic view of a part of the structure of the atomized medicine cup according to an embodiment of the present application. Referring to fig. 4, in order to reduce the number of parts for the sake of integral molding, an atomization baffle 204 located at the top of the conical flow guide cover 201 is integrally formed between two arc-shaped arms 203, and also in order to avoid the problem that the prior art cannot be integrally injection-molded, the atomization baffle 204 of the present application is located entirely outside the region surrounded by the cylindrical side wall 202. In the particular embodiment shown in FIG. 4, the upper edge of the atomizing baffle 204 is substantially flush with the lower edge of the cylindrical sidewall 202, or the upper edge of the atomizing baffle 204 is slightly lower than the lower edge of the cylindrical sidewall 202. It should be noted that for the purpose of integral molding, the conical flow guide cover 201, the arc-shaped arm 203, the atomizing baffle 204, etc. cannot extend into the inside of the area surrounded by the cylindrical sidewall 202, otherwise, the mold clamping and injection molding cannot be integrally performed.

Further, due to the lack of space between the aerosol generation region and the inhalation port in the prior art, the low-temperature aerosol medicine and air are directly inhaled by the patient, which is easy to stimulate the respiratory tract to cause cough, and the reverse flow of the patient cough air into the inhaler is easy to cause pollution. In response to this problem, the present application provides a very convenient solution, namely, as shown in fig. 2-4, by integrally forming a semi-annular partition 205 on the outside of the cylindrical side wall 202 to block half of the longitudinal air flow path between the cartridge 100 and the atomizing core 200.

The liquid medicine in the medicine containing barrel 100 is sucked out from the gap between the conical nozzle 101 and the conical drainage cover 201 by the injection action of the compressed air to be mixed with the compressed air, and then the liquid medicine collides with the atomization baffle 204 to form atomization action. That is, the lower edge of the atomizing baffle 204 is the main atomizing area.

In the prior art, no barrier exists between the atomization generating area and the breathing opening 102, and atomized liquid medicine is directly inhaled into the respiratory tract of a patient from the atomization generating area and is easy to choke to cause cough. In addition, when a patient inhales the medicine, the patient cannot stop at all, so that the patient always stops, the atomizer works all the time, and the atomized medicine can permeate into the whole medicine containing barrel 100. When a patient inhales the atomized medicine, the medicine between the atomization generating area and the breathing port 102 is easily sucked away, and the medicine dissipated to the non-inhalation channel range cannot be fully absorbed and utilized unless the patient inhales with great strength, which is originally difficult for the patient suffering from respiratory diseases, and particularly, the patient is easily choked by airflow with great strength to cause cough.

The solution of the present application is to provide a semicircular annular partition plate 205 on the upper portion of the atomization baffle plate 204 and on the lower portion of the breathing hole 102 of the drug container 100, and block a half of the longitudinal airflow channel between the drug container 100 and the atomization core 200 by the semicircular annular partition plate 205, as shown in fig. 3 and 5, wherein fig. 5 is a schematic sectional structure diagram of a compression atomizer according to still another embodiment of the present application. As is apparent from fig. 3 and 5, the semicircular partition plate 205 has a width that just fills half of the gap between the cartridge 100 and the atomizing core 200, and separates the area where the atomizing baffle 204 mainly generating the atomizing action is located from the breathing opening 102, so that when a patient inhales the medicine, the atomized medicine can only bypass the semicircular partition plate 205 and enter the breathing opening 102 from the other side around the cylindrical side wall 202 of the atomizing core 200. The end of the breathing port 102 may be connected to a breathing mask or the like.

This kind of blockage flourishing cartridge 100 and the design of atomizing core 200 between half longitudinal airflow channel's of this application semicircle annular baffle 205, the stimulation of prior art air current direct impact patient's respiratory track has been avoided, simultaneously through making the air current produce the air current swirl around atomizing core 200's cylindric lateral wall 202, attract out with the medicine of inside as far as with producing subsidiary suction force, can alleviate the inspiratory pressure of patient's strength, avoid further amazing and practice thrift the medicine, the gathering of inside medicine and the pollution of the anti-zone fungus air current of scurrying have been avoided, the safety in utilization of medical instrument has been improved.

Further, in order to improve the usage efficiency of the nebulizer, in one embodiment of the present application, as shown in fig. 2 to 5, the semicircular annular partition plate 205 is integrally formed at both ends thereof with a flow guiding side plate 206 extending vertically upward along the outer side of the cylindrical side wall 202, and the flow guiding side plate 206 is used for blocking a part of the annular air flow passage between the breathing opening 102 of the cartridge 100 and the nebulizing cartridge 200. That is, in the present embodiment, the diversion side plate 206 blocks a part of the circular airflow channel between the breathing opening 102 of the drug container 100 and the atomizing core 200, so that the airflow bypasses the semicircular partition plate 205 and continues to extend upwards along the diversion side plate 206, the length of the airflow channel is further lengthened, the impact of the airflow on the respiratory tract of the patient is alleviated, and a longer airflow channel can form a larger cyclone and suction effect, which is more beneficial to sucking out the atomized drug inside.

In another embodiment, as shown in fig. 3 and 5, the top of the flow-guiding side plate 206 exceeds half of the inner diameter of the breathing opening 102, so that the airflow tends to be sucked out downwards after turning over the flow-guiding side plate 206, and a relatively obvious vortex disturbance is formed at the top of the flow-guiding side plate 206, thereby increasing the suction force of the cyclone, and meanwhile, the atomization reduction caused by the overlong airflow channel can be broken up again through the vortex disturbance, thereby counteracting the disadvantage of the reduced atomization effect caused by the overlong airflow channel. Fig. 5 illustrates the deflector skirt 206 in phantom to show the height of the deflector skirt 206. In an embodiment not shown, a saw-tooth structure may be formed on the top of the deflector skirt 206 to enhance the turbulence effect on the airflow.

In yet another embodiment of the present application, the cartridge 100 is formed with a first handle 109 on the outside and the atomizing core 200 is formed with a second handle 209 on the outside of the top that is positioned with reference to the first handle 109. That is, in order to achieve the optimized atomization and treatment effects, the position of the semicircular partition plate 205 on the atomizing core 200 relative to the breathing opening 102 needs to be aligned according to the design drawing, and the position of the atomizing core 200 in the medicine container 100 can be accurately positioned by aligning the second handle 209 with the first handle 109, so as to avoid the influence of misalignment on the using effect.

Further, in order to avoid the atomizing air flow from being insufficient for suction, a rotary shutter 301 with an adjustable air inflow amount is provided on the cover 300 of the present application, and the air flow amount of the external air reaching the atomizing baffle 204 from the upper part through the atomizing core 200 can be adjusted by rotating the rotary shutter 301. When a patient inhales, atomized medicine generated below the atomization baffle plate 204 is mixed with outside air reaching the atomization baffle plate 204 by rotating the valve 301 in the area where the atomization baffle plate 204 is located, and the amount of air flow can be controlled through the valve 301. In addition, in order to facilitate the operation of the shutter 301, an operation vertical rod 302 is formed on the shutter 301.

On the other hand, it is also possible to prevent contaminants from falling into the drug container 100 by rotating the shutter 301 as an inlet port for the drug solution, without opening the cover 300.

In addition, the height of the liquid medicine added into the medicine container 100 preferably does not exceed the height of the conical nozzle 101, otherwise the liquid medicine flows back to the compressed air inlet 21, bubbles are continuously blown at the conical nozzle 101 after the compressed air enters, and the effect of atomizing the liquid medicine cannot be realized.

In another embodiment, in order to facilitate the medicine to enter the gap between the conical nozzle 101 and the conical drainage mask 201, a notch 208 for facilitating the liquid medicine to flow through is formed at the lower edge of the conical drainage mask 201, as shown in fig. 4.

In addition, the lower bottom surface of the medicine containing barrel 100 surrounding the conical nozzle 101 for containing the liquid medicine can be designed to be a conical structure, that is, the lower bottom surface for containing the liquid medicine is formed with a conical inclined surface which is folded downwards, so that the liquid medicine is favorably concentrated towards the bottom, and the residue is reduced. Because in the actual atomization process, under the impact of air current, can fill liquid medicine aerial fog in the atomizing medicine cup, a lot of liquid medicine liquid drops can be attached to the medicine cup wall naturally, if these liquid drops can not concentrate again, just can basically atomize, can lead to the liquid medicine to remain in a large number around the medicine cup bottom surface like this, the liquid medicine utilizes inadequately, extravagantly seriously. This application adopts the lower bottom surface of the toper structure of optimizing the structure, can avoid the not high problem of medicine residue utilization ratio.

In a further embodiment of the present application, as shown in fig. 2-5, the outer side of the cylindrical sidewall 202 of the atomizing core 200 is fastened with a flow guiding sleeve 400, the top of the flow guiding sleeve 400 abuts against the lower side of the semi-circular partition 205, and the bottom of the flow guiding sleeve 400 is lower than the lower edge of the atomizing baffle 204.

As mentioned above, the conical draft shield 201, the arc-shaped arm 203, the atomizing baffle 204, etc. cannot extend into the interior of the area surrounded by the cylindrical sidewall 202 for the purpose of integral molding. The lower edge of the atomizing baffle 204, which primarily forms the atomizing effect, is exposed outside the area surrounded by the cylindrical sidewall 202. When a patient inhales, the atomized medicine is directly sucked away from the lower edge of the atomization baffle 204, and is insufficiently mixed with the external air introduced from the upper part of the atomization baffle 204, so that the concentration change of the medicine in the airflow is possibly large, and the treatment effect is influenced.

Therefore, in the above embodiment, the guiding sleeve 400 shields the atomizing baffle 204, so that when a patient inhales, the atomized medicine and the outside air need to be sucked out from the lower portion of the guiding sleeve 400 in opposite directions, thereby forming a better mixing effect and improving the uniformity of the medicine concentration in the airflow. In addition, the flow guide sleeve 400 is positioned by the semi-circular partition plate 205, so that the flow guide sleeve 400 is firmly buckled on the outer side of the cylindrical side wall 202 of the atomizing core 200, and the flow guide sleeve is prevented from shaking and falling off in the air suction process. The flow sleeve 400 is equivalently formed integrally on the atomizing core 200 during disassembly and assembly, and does not require separate removal and handling.

Further, as shown in fig. 4, the flow sleeve 400 has a cylindrical portion 401 at the upper portion thereof, an annular flange 402 extending inward from the cylindrical portion 401 at the lower portion thereof, and notches 403 formed in the annular flange 402 and corresponding to the two arc-shaped arms 203. The inner diameter of the cylindrical portion 401 is slightly larger than or equal to the outer diameter of the cylindrical side wall 202. When the flow sleeve 400 is installed, the two notches 403 are aligned with the two arc-shaped arms 203, and the flow sleeve 400 is pushed against the lower side surface of the semicircular partition plate 205.

The outer side wall of the cylindrical side wall 202 is formed with a snap projection 207, and the inner side wall of the cylindrical portion 401 is formed with a protruding strip 407 snap-fitted with the snap projection 207. To facilitate the installation of the snap tab 207 in alignment with the rib 407, the rib 407 is preferably vertically disposed along the inner sidewall of the cylindrical portion 401 within the area of the alignment notch 403, so long as the two notches 403 are aligned with the two arcuate arms 203 during installation, it is ensured that the snap tab 207 can be snapped onto the lower edge of the rib 407, as shown in fig. 5.

To sum up, this application adopts two arc arms that extend downwards from the cylindric lateral wall of atomizing core, through two arc arm centre gripping toper drainage covers for the structure relevant with toper drainage cover all is located outside the region that the cylindric lateral wall centers on, therefore is convenient for carry out disposable injection moulding through the form of moulding, has realized an organic whole structure through the structure of optimizing, has simplified processing, has avoided bacterial contamination. In addition, the design of the semicircular annular partition plate avoids stimulation of airflow direct impact on the respiratory tract of a patient, and airflow vortexes are generated through the cylindrical side wall of the airflow surrounding the atomizing core to generate subsidiary suction force to attract out the internal medicine as much as possible, so that the powerful air suction pressure of the patient can be reduced, further stimulation and medicine saving are avoided, the pollution of gathering and anti-channeling of the internal medicine to the airflow with bacteria is avoided, and the use safety of medical equipment is improved.
