Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an atomizing inhaler and a medical device for atomization treatment. Background Art

[0002] Nebulization therapy mainly refers to aerosol inhalation therapy. The so-called aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, the aerosol inhalation therapy is to use a nebulizer to disperse the drug into tiny droplets or particles, suspend them in the gas, and allow them to enter the respiratory tract and lungs to achieve the purpose of cleaning the airway, humidifying the airway, local treatment or systemic treatment.

[0003] However, the existing nebulizer inhalers used for nebulization treatment have the defect of wasting drugs during the nebulization treatment process. Nearly half of the drug liquid is wasted in the air during exhalation. One of the drugs is called (Budesonide Dry Suspension for Inhalation). According to the China Pharmaceutical Network, the sales of this drug in the second quarter of 2016 alone reached 1.592 billion yuan. These expensive nebulizer drugs have to be wasted by existing technology, which will greatly increase the cost of nebulization treatment. Summary of the invention

[0004] The purpose of the present invention is to provide an atomizing inhaler and a medical device for atomizing treatment, so as to solve the technical problems of wasting medicine and increasing treatment cost existing in the prior art.

[0005] After studying the structure and treatment process of the nebulizer therapy device in the prior art, it was found that when the nebulizer therapy device in the prior art is used for nebulization therapy, the tiny droplets or particles formed by the drug will intermittently enter the patient's respiratory tract and dissipate in the air, that is, with the intermittent process of breathing and inhalation during the treatment process of the patient, when inhaling, the tiny droplets or particles formed by the drug will be inhaled into the respiratory tract, and when exhaling, the tiny droplets or particles formed by the drug will be blown out through the air holes set on the nebulizer therapy device and dissipated in the air.

[0006] However, the medicine that dissipates into the air during the patient's exhalation cannot be re-inhaled into the patient's respiratory tract, resulting in waste and failure to achieve the treatment purpose.

[0007] As we all know, the breathing process of the human body is intermittent and continuous. It is conceivable that in this normal breathing process, at least 50% of the drugs are wasted, resulting in a significant increase in costs.

[0008] The present invention provides an atomizing inhaler for atomization treatment, comprising:

[0009] A nebulizer spray device, used to atomize the drug;

[0010] gas tank;

[0014] The breathing mask is also provided with a second one-way air valve structure, allowing gas to be discharged from the inner cavity of the breathing mask to the outside.

[0015] Furthermore, in an embodiment of the present invention, at least a portion of the gas storage tank is retractable.

[0049] Figure 1 A schematic diagram of a partial structure of an atomizing inhaler provided by an embodiment of the present invention;

[0050] Figure 2 The overall structure diagram of the atomizing inhaler provided by one embodiment of the present invention is as follows; Figure 1 and Figure 2 As shown, this embodiment provides an atomizer inhaler for atomization therapy, comprising:

[0051] Atomizing spray device 1, used for atomizing the medicine;

[0052] Gas tank 2;

[0053] The inlet of the gas storage tank 2 is connected to the medicine outlet of the atomizing spray device 1;

[0054] Respiratory mask 3;

[0055] The medicine inlet of the breathing mask 3 is connected to the outlet of the gas storage tank 2, and a first one-way air valve structure 31 is provided between the breathing mask 3 and the gas storage tank 2 to allow the atomized medicine to flow from the gas storage tank 2 to the breathing mask 3;

[0056] The breathing mask 3 is also provided with a second one-way air valve structure 32 to allow gas to be discharged from the inner cavity of the breathing mask 3 to the outside.

[0057] As can be seen from the above, due to the structure of the nebulizer in the prior art, as the patient exhales and breathes intermittently during the treatment process, when inhaling, the tiny droplets or particles formed by the medicine will be inhaled into the respiratory tract, and when exhaling, the tiny droplets or particles formed by the medicine will be blown out through the air holes 313 set on the nebulizer and dissipated in the air, thereby causing a waste of medicine.

[0058] Therefore, in the process of the atomizing spray device 1 atomizing the medicine for the patient to inhale, the atomizing inhaler of the present application uses the gas storage tank 2 to store the atomized medicine to avoid the atomized medicine being dissipated in the air and wasted.

[0059] According to the nebulizer inhaler of the above structure, an air storage tank 2 connected to the breathing mask 3 via a first one-way air valve structure 31 is provided. After the nebulizer spray device 1 atomizes the medicine, the atomized medicine will first be discharged from the medicine outlet of the nebulizer spray device 1, enter the air storage tank 2 through the inlet of the air storage tank 2 connected thereto, and then be discharged from the outlet of the air storage tank 2, and enter the inner cavity of the breathing mask 3 through the first one-way air valve structure 31. When the patient wears the breathing mask 3, he can smoothly inhale the atomized medicine.

[0060] The first one-way air valve structure 31 allows the atomized medicine to flow from the gas tank 2 to the breathing mask 3, that is, through the first one-way air valve structure 31 arranged between the breathing mask 3 and the gas tank 2, only the atomized medicine can flow from the gas tank 2 to the breathing mask 3, but the gas cannot flow from the breathing mask 3 to the gas tank 2 in the opposite direction.

[0061] Therefore, when the patient inhales the medicine once and then exhales, the first one-way air valve structure 31 is closed, preventing the gas exhaled by the patient during the exhalation process from entering the gas storage tank 2, and instead the exhaled gas is discharged to the outside of the breathing mask 3 from the second one-way air valve structure 32 provided on the breathing mask 3.

[0062] While the patient is exhaling, that is, while the exhaled gas is discharged from the second one-way air valve structure 32 to the outside of the breathing mask 3, the atomizing spray device 1 continuously provides atomized medicine. Unlike the prior art, although the atomized medicine is continuously provided, it is not carried into the air by the patient's exhaled gas to dissipate, but is stored in the gas storage tank 2 under the guidance of pressure.

[0063] When the patient performs the next round of inhalation and exhalation, due to the influence of suction pressure, the atomized medicine will enter the breathing mask 3 again through the first one-way air valve structure 31, and then be inhaled into the respiratory tract by the patient.

[0064] Therefore, by using this nebulizer inhaler, all the atomized medicine can be inhaled into the patient's respiratory tract without dissipating in the air and causing waste.

[0065] Furthermore, in an embodiment of the present invention, at least a portion of the gas storage tank 2 is retractable.

[0066] During the process of the patient's exhalation, that is, during the process of the exhaled gas being discharged from the second one-way air valve structure 32 to the outside of the breathing mask 3, the atomizing spray device 1 continuously provides atomized medicine.

[0067] If the patient does not completely inhale the medicine during the next inhalation process, the continuously provided atomized medicine will gradually fill up the gas storage tank 2. As the amount of medicine in the gas storage tank 2 increases, it is easy to cause excessive pressure in the gas storage tank 2, causing the patient to be forced to inhale, resulting in discomfort.

[0068] Therefore, when a retractable structure is provided on at least a portion of the gas storage tank 2, when the internal pressure is too high, the internal pressure can be relieved by the retractable portion, so that the patient can have a buffer time to absorb the medicine, thereby preventing the entire process of inhaling the medicine from being rushed and causing discomfort.

[0069] Preferably, in the embodiment of the present invention, the gas storage tank 2 is provided with at least one retractable air bag portion 22 .

[0070] Therefore, an airbag portion 22 may be provided on the air storage tank 2. The airbag portion 22 has a telescopic effect and may be made of rubber material, for example.

[0071] Preferably, in an embodiment of the present invention, the gas storage tank 2 includes a retractable air bag.

[0072] In order to obtain a greater buffering effect, the entire gas storage tank 2 can be replaced by an air bag, which can store gas and also has the effect of expansion and contraction and buffering pressure.

[0073] Furthermore, in an embodiment of the present invention, a third one-way gas valve structure 21 is provided on the gas storage tank 2 to allow gas to enter the inner cavity of the gas storage tank 2 from the outside of the gas storage tank 2 .

[0074] Because the patient's inhalation and exhalation process, the amount of air inhaled in a single breath is uneven, that is, the problem of occasionally inhaling a large amount of air may occur.

[0075] Therefore, if the single inhalation volume is large and the entire device is airtight, it will cause inhalation to be unsmooth.

[0076] By providing the third one-way valve structure 21, when the patient inhales a large amount of air at a time, the third one-way valve structure 21 can be automatically opened to allow the outside air to pass through the gas storage tank 2 and enter the breathing mask 3 along with the medicine, thereby allowing the patient to inhale a large amount of gas, forming an inhalation effect with a large amount of air.

[0077] Figure 3 A schematic structural diagram of a first partition 311 provided in one embodiment of the present invention; Figure 4 The overall structural diagram of the first one-way air valve structure 31 provided in one embodiment of the present invention is as follows; Figure 3 and Figure 4 As shown, in an embodiment of the present invention, the first one-way air valve structure 31 includes a first baffle 311 having an air hole 313 and a first flexible sheet 312 partially connected to the first baffle 311;

[0078] The first flexible sheet 312 covers the air hole 313 to close the air hole 313;

[0079] The first partition 311 is arranged at the medicine inlet of the breathing mask 3 or the outlet of the gas storage tank 2 .

[0080] Of course, in addition to the above structure, those skilled in the art may also select other one-way valve structures that allow gas to flow in one direction according to their needs, which is not limited here.

[0081] Similarly, referring to the structure of the first one-way air valve structure 31, in an embodiment of the present invention, the second one-way air valve structure 32 includes a second baffle having an air hole 313 and a second flexible sheet partially connected to the second baffle;

[0082] The second flexible sheet covers the air hole 313 to close the air hole 313;

[0083] The second partition is arranged on the side wall of the breathing mask 3 .

[0084] Similarly, referring to the structure of the first one-way valve structure 31, in the embodiment of the present invention, the third one-way valve structure 21 includes a third baffle having an air hole 313 and a third flexible sheet partially connected to the third baffle;

[0085] The third flexible sheet covers the air hole 313 to close the air hole 313;

[0086] The third partition is arranged on the side wall of the gas storage tank 2 .

[0087] Preferably, in an embodiment of the present invention, two second one-way air valve structures 32 are provided;

[0088] The two second one-way air valve structures 32 are symmetrically arranged on both sides of the breathing mask 3 .

[0089] The two second one-way air valve structures 32 are symmetrically arranged to ensure that the exhaled gas is discharged more evenly.

[0090] The present invention also provides a medical device, comprising the atomizing inhaler.
