Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, unless explicitly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected via an intervening medium, or in communication between two elements. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
FIG. 1 is a schematic view of a part of a nebulizer according to an embodiment of the invention;
fig. 2 is a schematic view of the overall structure of an aerosol inhaler according to an embodiment of the present invention, and as shown in fig. 1 and 2, the aerosol inhaler for aerosol treatment according to the present embodiment includes:
An atomizing spray device 1 for atomizing a medicine;
A gas tank 2;
the inlet of the air storage tank 2 is communicated with the medicine outlet of the atomizing spray device 1;
A respiratory mask 3;
The medicine inlet of the breathing mask 3 is communicated with the outlet of the air storage tank 2, and a first one-way air valve structure 31 is arranged between the breathing mask 3 and the air storage tank 2 to allow atomized medicine to flow from the air storage tank 2 to the breathing mask 3;
The breathing mask 3 is further provided with a second one-way gas valve structure 32 allowing gas to be discharged from the inner chamber of the breathing mask 3 to the outside.
Therefore, as the structure of the aerosol inhaler in the prior art is along with the intermittent process of breathing and inhaling during the treatment of patients, tiny fog drops or particles formed by the medicine are inhaled into the respiratory tract during inhalation, and the tiny fog drops or particles formed by the medicine are blown out through the air holes 313 arranged on the aerosol therapeutic device during exhalation, so that the medicine is dissipated in the air, and further the medicine is wasted.
Therefore, in the atomization inhaler of the application, the air storage tank 2 is adopted to store the atomized medicine in the process of atomizing the medicine by the atomization spraying device 1 for the patient to inhale, so that the atomized medicine is prevented from being dispersed in the air to form waste.
According to the aerosol inhaler of the above structure, the air storage tank 2 connected with the breathing mask 3 through the first one-way air valve structure 31 is provided, when the aerosol spray device 1 atomizes the medicine, the atomized medicine is discharged from the medicine outlet of the aerosol spray device 1, enters the air storage tank 2 through the inlet of the air storage tank 2 communicated with the aerosol spray device, then is discharged from the outlet of the air storage tank 2, enters the inner cavity of the breathing mask 3 through the first one-way air valve structure 31, and the patient brings the breathing mask 3, so that the atomized medicine can be inhaled smoothly.
The first one-way gas valve structure 31 allows the atomized medicine to flow from the gas reservoir 2 to the breathing mask 3, i.e. only the atomized medicine can flow from the gas reservoir 2 to the breathing mask 3, but not the gas can flow from the breathing mask 3 to the gas reservoir 2 in a reverse direction, by means of the first one-way gas valve structure 31 arranged between the breathing mask 3 and the gas reservoir 2.
Therefore, when the patient exhales with the medicine once, the first one-way valve structure 31 is closed, and the gas from the patient exhaled during the expiration is prevented from entering the gas tank 2, and the exhaled gas is exhausted to the outside of the breathing mask 3 from the second one-way valve structure 32 provided on the breathing mask 3.
While the nebulized aerosol apparatus 1 is continuously supplied with nebulized medicament during exhalation by the patient, i.e. during the discharge of exhaled gas from the second one-way gas valve arrangement 32 to the outside of the respiratory mask 3, unlike the prior art, in which nebulized medicament is continuously supplied, but is not carried over to the air by the patient for dissipation, but is stored in the reservoir 2 as a result of the pressure.
When the patient inhales and exhales for the next round, the atomized medicine can enter the breathing mask 3 again through the first one-way air valve structure 31 due to the influence of suction pressure, and then the patient inhales to the respiratory tract.
Therefore, the atomized medicine can be completely inhaled into the respiratory tract of a patient by using the atomization inhaler without being dispersed in the air, so that waste is formed.
Further, in an embodiment of the present invention, at least a portion of the air tank 2 has stretchability.
The nebulizing aerosol apparatus 1 is continuously provided with nebulized medicament since the expired air is discharged from said second one-way gas valve structure 32 to the outside of the respiratory mask 3 during exhalation by the patient.
If the patient does not completely inhale the medicine during the subsequent inhalation, the continuously supplied atomized medicine gradually fills the air reservoir 2. With more and more medicines in the air storage tank 2, the excessive pressure in the air storage tank 2 is easy to cause, so that a patient is forced to suck, and the feeling of medicine suction is uncomfortable.
Therefore, when the structure with elasticity is arranged on at least one part of the air storage tank 2, when the internal pressure is too large, the internal pressure can be relieved through the part with elasticity, so that a patient can absorb the medicine in a buffering time, and the whole medicine absorption process is prevented from being rapid, and the medicine absorption is uncomfortable.
Preferably, in the embodiment of the present invention, at least one air bag portion 22 having scalability is provided on the air tank 2.
Therefore, the air tank 2 may be provided with the air bag portion 22, and the air bag portion 22 may have an expansion and contraction effect, and may be made of rubber, for example.
Preferably, in an embodiment of the present invention, the air tank 2 includes an air bag having stretchability.
In order to obtain a larger buffering effect, the whole air storage tank 2 can be replaced by an air bag, namely the air storage tank can store air and has the effects of stretching and buffering pressure.
Further, in the embodiment of the present invention, a third one-way air valve structure 21 is provided on the air tank 2 to allow air to enter the inner cavity of the air tank 2 from the outside of the air tank 2.
Because the uneven inhalation amount of single inhalation is considered in the process of exhaling and inhaling of a patient, the problem of larger inhalation amount occasionally occurs.
Therefore, if the single inhalation amount is large, the whole device is airtight, and thus the inhalation is not smooth.
The third one-way air valve structure 21 is arranged, so that when the single inhalation amount of a patient is large, the third one-way air valve structure 21 can be automatically opened, and the outside air passes through the air storage tank 2 and enters the breathing mask 3 along with the medicine, so that the patient can be allowed to inhale a large amount of air, and an inhalation effect with large inhalation amount is formed.
Fig. 3 is a schematic structural view of a first partition plate 311 according to an embodiment of the present invention, fig. 4 is a schematic structural view of a first one-way valve structure 31 according to an embodiment of the present invention, and as shown in fig. 3 and 4, in an embodiment of the present invention, the first one-way valve structure 31 includes a first partition plate 311 having air holes 313 and a first flexible sheet 312 partially connected to the first partition plate 311;
the first flexible sheet 312 covers the air hole 313 and is used for closing the air hole 313;
the first baffle 311 is arranged at the medicine inlet of the breathing mask 3 or the outlet of the air storage tank 2.
Of course, in addition to the above structure, those skilled in the art may select other one-way valve structures with one-way air flow allowing function according to the requirements, and the invention is not limited thereto.
Similarly, referring to the structure of the first one-way valve structure 31, in an embodiment of the present invention, the second one-way valve structure 32 includes a second partition plate having air holes 313 and a second flexible sheet having a portion connected to the second partition plate;
The second flexible sheet covers the air hole 313 and is used for closing the air hole 313;
The second partition is provided on the side wall of the breathing mask 3.
Similarly, referring to the structure of the first one-way valve structure 31, in an embodiment of the present invention, the third one-way valve structure 21 includes a third partition plate having an air hole 313 and a third flexible sheet having a portion connected to the third partition plate;
the third flexible sheet covers the air hole 313 and is used for closing the air hole 313;
the third partition plate is arranged on the side wall of the air storage tank 2.
Preferably, in the embodiment of the present invention, the second one-way air valve structure 32 is provided with two;
the two second one-way air valve structures 32 are symmetrically arranged at two sides of the breathing mask 3.
The symmetrical arrangement of the two second one-way air valve structures 32 can ensure more uniform discharge process of the exhaled air.
The invention also provides a medical device comprising the aerosol inhaler.
Because the specific structure, functional principle and technical effect of the aerosol inhaler are described in detail above, the detailed description is omitted here.
Therefore, any technical content related to the aerosol inhaler may be referred to the description of the aerosol inhaler.
