Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a novel portable dry salt aerosol generator. Background Technology

[0002] Salt therapy is frequently used to treat respiratory diseases in European countries. In China, it was first used in some hospitals in 1997 to treat respiratory diseases. Currently, some medical institutions in China use it to treat respiratory diseases such as pneumoconiosis. In the non-hospital market, many institutions have established salt therapy rooms to provide salt therapy services to patients with respiratory diseases. Dry salt aerosol therapy involves grinding dry salt into micron-sized powder, mixing it with compressed air to form a salt aerosol. Salt particles with a diameter of 1-5μm are inhaled deep into the trachea by the patient, achieving the effects of eliminating mucosal edema, reducing respiratory inflammation, enhancing ciliary clearance function, improving drainage, improving blood microcirculation in the affected area, and flushing and cleaning the respiratory tract. However, most dry salt aerosol therapies currently on the market are in the form of salt therapy rooms, which are large, costly, and not convenient for people to use or carry.

[0003] Therefore, it is necessary to design a nebulizer that can produce dry salt aerosols for inhalation therapy through a face mask, thereby solving the technical problems mentioned above, such as the large size and high cost of salt therapy rooms, which are not conducive to portability and use. Summary of the Invention

[0004] The purpose of this invention is to provide a novel portable dry salt aerosol generator, which solves the technical problems of existing salt therapy chambers being large, expensive, and unsuitable for portability and use. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a novel portable dry salt aerosol generator, comprising a dry salt atomization mechanism, an atomization buffer mechanism, and an atomization inhalation mechanism;

[0007] The atomizing buffer mechanism is connected at one end to the dry salt atomizing mechanism and at the other end to the atomizing inhalation mechanism;

[0008] The dry salt atomizing mechanism includes an atomizing canister, nozzles, and an air vent. There are two or more nozzles. The nozzles are disposed on the outer wall of the atomizing canister. One end of the nozzle extends into the atomizing canister, and the other end is located outside the atomizing canister and connected to the air vent. A high-speed airflow is introduced into the end of the air vent that is away from the nozzle.

[0009] The nozzle faces the bottom of the atomizing can, and the axis of the nozzle is out of plane from the axis of the atomizing can.

[0012] Preferably, the flow-blocking part is a multi-layer flow-blocking plate, the flow-blocking plate has gaps, and the two sides of the gaps are beveled fan blades.

[0013] Preferably, the flow-blocking part is a pipe diverter, and the branch outlets of the pipe diverter are all connected to the atomizing inhalation mechanism.

[0014] Preferably, a tightening part is provided in the middle of the buffer tank, the diameter of the tightening part is smaller than the diameter of the buffer tanks at both ends, and the diameter of the nozzle is smaller than the diameter of the tightening part.

[0015] Preferably, the nebulizing inhalation mechanism includes a medical nebulizing corrugated tube and a nebulizing inhalation mask, with one end of the medical nebulizing corrugated tube connected to the nebulizing buffer mechanism and the other end connected to the nebulizing inhalation mask.

[0019] The technical solution provided by this invention includes a dry saline nebulizer, a nebulization buffer mechanism, and a nebulization inhalation mechanism. The dry saline nebulizer includes a nebulizer canister, nozzles, and an air duct. There are two or more nozzles, which are disposed on the outer wall of the nebulizer canister.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] A specific embodiment of the present invention provides a novel portable dry salt aerosol generator, as shown in the attached figure. Figure 1 - Appendix Figure 3As shown, it includes a dry salt nebulizer 1, a nebulizer buffer 2, and a nebulizer inhalation 3; one end of the nebulizer buffer 2 is connected to the dry salt nebulizer 1, and the other end is connected to the nebulizer inhalation 3; the dry salt nebulizer 1 is used to form a rotating dry salt aerosol mist by passing powdered dry salt through a high-speed airflow, and then the nebulizer buffer 2 buffers a large amount of dry salt aerosol so that a smaller portion can be released through the nebulizer inhalation 3 and finally supplied to the patient.

[0030] The specific dry salt atomizing mechanism 1 includes an atomizing canister 4, a nozzle 5, and an air duct 6. The atomizing canister 4 contains dry salt powder. The nozzle 5 is used to introduce a high-speed airflow into the atomizing canister 4. The air duct 6 is used to connect the nozzle 5 to the air duct 6. A medical air compressor pump 12 is used to provide a high-speed airflow for the novel portable dry salt aerosol generator. In this application, there are two or more nozzles 5. The nozzles 5 are set on the outer wall of the atomizing canister 4. One end of the nozzle 5 extends into the atomizing canister 4, and the other end is located outside the atomizing canister 4 and connected to the air duct 6. The high-speed airflow is introduced into the end of the air duct 6 away from the nozzle 5. The high-speed airflow passes through the air duct. 6. The high-speed airflow from nozzle 5 propels dry saline powder into the nebulizer 4, forming a dry saline aerosol. To ensure the aerosol passes sequentially through the nebulization buffer mechanism 2 and the nebulization inhalation mechanism 3 before being supplied to the patient, the nozzle 5 is positioned in a specific way. Nozzle 5 must face the bottom of the nebulizer 4 so that the high-speed airflow directly contacts the dry saline powder at the bottom. Furthermore, the axis of nozzle 5 must be parallel to the axis of the nebulizer 4. This arrangement creates a rotating airflow within the nebulizer 4, which in turn carries the dry saline powder upwards into the nebulization buffer mechanism 2. The high-speed airflow from nozzle 5 provides the power for this rotating airflow.

[0031] The number of nozzles 5 used in this application can be two, three, four, five, or six. The preferred option is to have three nozzles 5, which are evenly distributed around the circumference of the atomizing can 4. The multiple nozzles 5 are arranged on the same horizontal plane of the atomizing can 4. The nozzles used in this application are atomizing nozzles, which make the sprayed gas form a large surface that can quickly drive the dry salt powder in the atomizing can 4. The nozzles 5 are arranged in the lower half of the atomizing can 4, so that the nozzles 5 are close to the dry salt powder at the bottom of the atomizing can 4 and can provide sufficient power.

[0032] Specifically, this application provides a certain way of setting the nozzle 5. The angle between the nozzle 5 and the horizontal plane is in the range of 10 degrees to 60 degrees, that is, the downward tilt angle of the nozzle 5 is in the range of 10 degrees to 60 degrees. Since the axis of the nozzle 5 and the axis of the atomizing can 4 are in a non-plane state, the point where the nozzle 5 and the atomizing can 4 are connected is the connection point. The angle between the axial section of the atomizing can 4 passing through the connection point and the nozzle 5 is in the range of 10 degrees to 60 degrees. In this way, the nozzle 5 is set at an angle downward. The downward direction is more likely to blow dry salt powder, and the tilting direction provides rotational power for the blown dry salt powder.

[0033] In the structure of the three nozzles 5 provided in this application, the angle between the nozzle 5 and the axial section of the atomizing can 4 passing through the connection point is set to 50 degrees. At the same time, the angle between two of the nozzles 5 and the horizontal plane is 35 degrees, and the angle between one of the nozzles 5 and the horizontal plane is 50 degrees. The nozzle 5 with the 50-degree angle to the horizontal plane mainly blows the dry salt powder at the bottom of the atomizing can 4, while the other two nozzles 5 with the 35-degree angle to the horizontal plane provide more rotational power for the dry salt powder.

[0034] The nebulization buffer mechanism 2 is connected to the upper end of the nebulizer 4. The rotating and rising dry saline aerosol generated by the nebulizer 4 enters the nebulization buffer mechanism 2 for buffering. Since the concentration of dry saline aerosol formed in the nebulizer 4 is relatively high, but such a high concentration is not required for patient inhalation therapy, the nebulization buffer mechanism 2 is needed to supply only a portion of the dry saline aerosol to the patient for inhalation therapy. Specifically, the nebulization buffer mechanism 2 includes a buffer tank 7 and a flow-blocking part 8. One end (bottom end) of the buffer tank 7 is connected to the nebulizer 4, and the other end (top end) is provided with the flow-blocking part 8, which is connected to the nebulization inhalation mechanism 3. The buffer tank 7 needs to have a tightening part 9 in the middle of its tank body. The diameter of the tightening part 9 is smaller than the diameter of the two ends of the buffer tank 7. The narrow space formed inside the tank body of the tightening part 9, with two conical tips connected, reduces the amount of dry saline aerosol allowed to pass through, thus playing a buffering role.

[0035] The flow-blocking part 8 provided in this application can use a nozzle with a smaller diameter to achieve the flow-blocking effect and limit the content of dry salt aerosol in the ejected gas. The diameter of the nozzle is set to be smaller than the diameter of the constriction part 9, which further reduces the content of dry salt aerosol passing through and increases the intensity of the ejected dry salt aerosol airflow supplied to the patient.

[0036] The flow-blocking part 8 can also be configured as shown in the attached figure. Figure 2The multi-layer baffle structure shown resembles a louvered air vent. Through the slit plate, the inclined blades on both sides of the slits can effectively block dry salt particles in the gas, thereby reducing the dry salt content in the dry salt aerosol. Specifically, the slit width on the lower baffle 8 should be greater than the slit width on the upper baffle 8, so that the dry salt particles blocked by the blades can effectively fall back into the lower buffer tank 7. This setting can also reduce the dry salt content in the sprayed dry salt aerosol, making it more suitable for patients.

[0037] The flow-blocking part 8 can also be configured as shown in the attached figure. Figure 3 The shown tubing splitter structure can split the gas passing through the buffer tank 7. Multiple nebulizers 3 are connected to the other end of the tubing splitter, so that it can supply gas to multiple patients at the same time, which greatly facilitates the use of multiple patients.

[0038] To facilitate patient use, the nebulizer inhalation mechanism 3 is designed as a medical nebulizer corrugated tube 10 and a nebulizer inhalation mask 11. The medical nebulizer corrugated tube 10 is relatively soft and convenient for patients to use. One end of the medical nebulizer corrugated tube 10 is connected to the nebulizer buffer mechanism 2 and the other end is connected to the nebulizer inhalation mask 11. The nebulizer inhalation mask 11 is convenient for patients to wear.

[0039] Alternatively, an outer casing can be provided, housing the dry salt nebulizer 1, the nebulizer buffer 2, and the medical air compressor pump 12, making the whole unit modular. Only the medical nebulizer corrugated tube 10 and the nebulizer inhalation mask 11 need to be exposed on the outside for use. At the same time, a control switch and a power connection line are also provided on the outer casing to control the operation of the medical air compressor pump 12 and its power supply.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
