Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a micro-net atomizer. Background Art

[0002] Aerosol inhalation is a direct drug delivery method targeting the respiratory tract and lungs, with the advantages of rapid onset, high local drug concentration, small dosage,

[0003] Due to its advantages such as easy application and few systemic adverse reactions, it has become an important treatment for respiratory system-related diseases.

[0004] Commonly used on the market are ultrasonic nebulizers, compression nebulizers and micro-mesh nebulizers:

[0005] Ultrasonic nebulizer: Ultrasonic nebulizer uses a high-power triode to amplify the oscillation signal from the main circuit board and transmit it to the ultrasonic chip. The ultrasonic chip converts electrical energy into ultrasonic energy. The ultrasonic energy atomizes the water-soluble medicine into tiny mist particles of 1μm to 5μm at room temperature. With the help of the internal fan wind, the medicine is sprayed into the patient's airway and then inhaled by the patient. The nebulizer has high power consumption, is inconvenient to carry, has a large fan running noise, and requires special cleaning methods. The ultrasonic chip is very fragile and can be easily damaged if not handled properly.

[0006] Compressed nebulizer: Based on the Venturi jet principle, compressed air is used to form a high-speed airflow through a small tube. The negative pressure generated drives the liquid or other fluid to be sprayed onto the obstruction. Under the high-speed impact, the droplets are splashed around and become mist particles that are sprayed out from the outlet pipe. Generally, a larger nebulizer host is required, which is difficult to carry and noisy. The particle size of the nebulizer is also relatively large, and the treatment effect is not ideal.

[0007] Micromesh nebulizer: The micromesh nebulizer uses the reverse electric effect of piezoelectric ceramics to generate tiny ultrasonic vibrations, drive the mesh atomizer to vibrate at the same frequency, and squeeze the liquid medicine through the holes of the mesh atomizer to form atomized particles. The atomized particle size of the micromesh nebulizer is smaller than that of the other two nebulizers, and the noise is also smaller, which is convenient to carry. However, the existing micromesh nebulizers on the market are generally used at home, which cannot meet clinical needs, and there is only one operating mode (commonly continuous mode) and only one gear, which cannot be selected according to the actual needs of patients. In addition, the micromesh nebulizers on the market generally have a timing function, and the atomization will stop in 10-15 minutes. When the amount of medicine is large and cannot be completely atomized within 15 minutes, there will be excess medicine and the utilization rate is low.

[0008] In summary, the commonly used atomizers currently have the following disadvantages:

[0009] Ultrasonic nebulizers consume a lot of power and are not easy to carry. The atomized particle size is relatively large, the therapeutic effect is not good, and special cleaning methods are required. The ultrasonic chip is very fragile and can be easily damaged by improper operation. Compressed nebulizers generally require a larger nebulizer host, which is difficult to carry and makes a lot of noise, causing trouble to patients. The atomized particle size is also large, and the proportion of particles smaller than 5μm is very small, resulting in poor therapeutic effect. Micromesh nebulizers generally have only one fixed operating mode (commonly continuous mode) and a fixed atomization rate gear, which cannot be selected according to needs, and are mostly used at home. They cannot be adapted to patients who have undergone tracheotomy in the hospital and cannot nebulize themselves, and have poor adaptability. Utility Model Content

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] The purpose of the utility model is to provide a micro-mesh atomizer to solve the problems existing in the prior art.

[0048] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The micro-grid atomizer in this embodiment is as follows: Figure 1-Figure 10 As shown, it includes a host 3 and an inhalation accessory 5. The host 3 is connected to the inhalation accessory 5 to control the working state of the inhalation accessory 5; the host 3 is connected to the power supply through the power adapter 1; the host 3 and the inhalation accessory 5 are electrically connected through an extension line 4, which can be retracted and convenient to carry, thereby solving the problems of patients turning over, moving, and distance during clinical use.

[0050] The host 3 includes a shell, a controller arranged in the shell, a gear controller 3-5, a switch button 3-3 and a gear adjustment knob 3-2 arranged outside the shell. The gear controller 3-5 is connected to the controller. The gear adjustment knob 3-2 is rotated to control the gear controller 3-5 to switch the gear. The gear controller 3-5 adjusts the gear so that the controller controls the suction accessory 5 to a continuous mode or a pulse mode. Both the continuous mode and the pulse mode include multiple different gears.

[0051] In this specific embodiment, the continuous mode includes three gears: low, medium and high. Different gears can be selected for nebulization therapy according to the patient's tolerance; the pulse mode gears include three gears: 12PPM, 20PPM, and 36PPM (PPM: times / minute). It can be matched according to the patient's breathing rhythm or the set rhythm of the ventilator, and the best gear can be selected for nebulization therapy to ensure the maximum utilization of the nebulized drug and better treatment effect; a gear indicator light 3-1 corresponding to the corresponding gear is set on the outer casing.

[0052] Continuous mode: continuous spraying after turning on;

[0053] Pulse mode: After starting up, spray and pause according to the frequency set by the program, with a duty cycle of 50%;

[0054] 12PPM: spray for 2.5 seconds, pause for 2.5 seconds;

[0055] 20PPM: spray for 1.5 seconds, pause for 1.5 seconds;

[0056] 36PPM: spray for 0.83 seconds, pause spray for 0.83 seconds;

[0057] The working principles of the two modes are the same as the atomization principle. Both modes generate an alternating voltage of a specific frequency through program control, which is applied to the two electrodes of the piezoelectric ceramic, causing the piezoelectric ceramic to deform, driving the micro-mesh tightly bonded to the piezoelectric ceramic to vibrate, squeezing the medicine in the medicine cup, and causing the medicine to spray out of the medicine cup from the micropores of the mesh.

[0058] Gear control principle: The gear controller 3-5 has a total of 12 gears, and the wires are only connected to 6 guide pillars. By rotating the knob 3-2, the internal gear controller 3-5 is driven to rotate, thereby achieving the purpose of gear adjustment.

[0059] In this embodiment, the inhalation accessory 5 includes a spray head assembly 5-1, a three-way connection 5-2, a mouthpiece 5-3, a large mask 5-4 and a small mask 5-5. The spray outlet of the spray head assembly 5-1 is connected to the three-way connection 5-2 or the mouthpiece 5-3 or the large mask 5-4 or the small mask 5-5. The spray head assembly 5-1 and the three-way connection 5-2 can be matched with the ventilator pipeline. The large mask 5-4 and the small mask 5-5 in the spray head assembly 5-1 can be selected according to the patient's identity (adult, child), the mouthpiece 5-3 can be selected and used according to the patient's needs (some patients with facial injuries or when they do not carry masks, they can choose the mouthpiece 5-3), the three-way connection 5-2 can be matched with the ventilator pipeline 7, and the atomization treatment is performed on patients who have tracheotomy or cannot use masks and mouthpieces 5-3, and the adaptability is stronger.

[0060] In this specific embodiment, a hanger assembly 2 is also provided on the shell, and the hanger assembly 2 includes a hanger 2-1, a fixed handle and a fixed clamp 2-2. Fixed handle; 2-3, the hanger 2-1 is sleeved on the outside of the shell, and the back of the hanger 2-1 is provided with a fixed clip 2-2. Fixed handle; 2-3, the fixed clamp 2-2. Fixed handle; 2-3 can be clamped to the outside of the infusion stand 6 through the fixed handle, which is convenient for operation and storage.

[0061] In this specific embodiment, a power indicator light 3-4 is also provided on the housing to indicate whether the power is on.

[0062] In this specific embodiment, the inhalation accessory 5 includes a spray head assembly 5-1 and a spray outlet, and a liquid level probe 5-11 and an atomizing sheet 5-12 are arranged inside the spray head assembly 5-1, and the liquid level probe 5-11 is connected to the extension line 4 through the spring terminal 4-1. The setting of the liquid level probe 5-11 enables the atomizer to have a residual liquid prompt function, and both the continuous mode and the pulse mode can be realized. After the liquid medicine is sprayed, the atomizing sheet 5-12 stops vibrating, triggering an audible and visual prompt, and automatically shuts down after 1 minute, and will not continue to dry burn.

[0063] The residual liquid prompt principle is: under working condition, during normal spraying, the residual liquid probe at the bottom of the medicine cup is in contact with the medicine liquid, and the metal part of the atomizer sheet 5-12 at the front of the medicine cup is also in contact with the medicine liquid. The medicine liquid is a conductive aqueous solution, so the metal part of the atomizer sheet 5-12 and the residual liquid probe are in a conductive state; during the atomization process, the medicine liquid gradually decreases until there is no medicine liquid at the residual liquid probe at the bottom of the medicine cup, at which time the metal part of the atomizer sheet 5-12 and the residual liquid probe are in a non-conductive state.

[0064] In this specific embodiment, the size of the shell is 110*52*26mm (length*width*height), which has the advantages of being small and easy to carry.

[0065] The utility model uses specific examples to illustrate the principle and implementation of the utility model. The above examples are only used to help understand the method and core idea of ​​the utility model. At the same time, for those skilled in the art, according to the idea of ​​the utility model, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
