Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to an emergency nebulizer. Background Technology

[0002] In outdoor emergency rescue scenarios, the combined implementation of nebulized drug administration and oxygen supply is a key means of rescuing patients with respiratory diseases (such as acute asthma and pulmonary edema) and traumatic hypoxia. However, existing technical solutions have significant drawbacks: mainstream solutions use a combination of independent devices, such as a nebulizer and a portable oxygen concentrator, which increases the burden of carrying the equipment and makes it difficult to meet the timeliness requirements of immediate treatment in outdoor emergency rescue scenarios.

[0003] Furthermore, traditional nebulization technology primarily utilizes compressed air or ultrasonic principles to atomize medication, generating fine droplets that are inhaled into the respiratory tract during deep inhalation to exert therapeutic effects. Traditional compressed air nebulizers break up the medication with high-speed airflow, but uncontrollable turbulence often results in an excessively wide distribution of atomized particle diameters, affecting the drug's deposition location and efficacy in the airways and lungs. While traditional ultrasonic nebulizers offer superior atomization, they typically operate at a single frequency, leading to higher atomization efficiency for certain particle sizes while other particle sizes remain insufficiently atomized, impacting drug delivery and absorption efficiency.

[0004] Therefore, there is a need to propose an emergency nebulizer that solves the problems of complex nebulization and oxygen supply devices, poor portability, and uneven drug atomization particles affecting drug deposition and efficacy in outdoor emergency rescue scenarios.

The nebulizer body 1 includes a mask connection port 11, an oxygen cylinder connection port 12, a top cover 13, a nebulization switch 14, and an isolation plate 18. The mask connection port 11 and the oxygen cylinder connection port 12 are located on opposite sides of the nebulizer body 1. The breathing mask 2 and the oxygen cylinder 3 are connected to the mask connection port 11 and the oxygen cylinder connection port 12, respectively. The medicine cup 4, the ultrasonic nebulizing plate 5, and the main control module are installed inside the nebulizer body 1, with the medicine cup 4 installed above the main control module. The top cover 13 is used to seal the top of the nebulizer body 1. Specifically, when the top cover 13 is placed on top of the atomizer body 1, the outer diameter of the top cover 13 is larger than the outer diameter of the top of the atomizer body 1, and part of the top cover 13 abuts against the inner wall of the atomizer body 1 to seal the atomizer body 1; furthermore, a fixing block is provided on the outer side of the atomizer body 1, and the edge of the top cover 13 is locked under the fixing block to prevent the top cover 13 from flipping open during use. When it is necessary to add medicine to the medicine cup 4, the top cover 13 can be opened to add medicine to the medicine cup 4.

[0022] For details, please refer to Figures 2 to 7 The inner wall of the atomizer body 1 is provided with a guide portion 15, and the outer wall of the medicine cup 4 is provided with an arc-shaped groove 45 that matches the guide portion 15. When the medicine cup 4 is installed inside the atomizer body 1, the guide portion 15 is located within the arc-shaped groove 45. (Reference) Figure 2 The main control module includes a control board 61 and a battery 62, which are electrically connected. The battery 62 powers the emergency nebulizer and is detachably installed in the nebulizer body. The battery 62 can be directly charged or replaced, which is common prior art and is not limited in this embodiment. The nebulizer switch 14 is electrically connected to the control board 61. In this embodiment, the control board 61 is common prior art and will not be described in detail. The ultrasonic atomizing plate 5 is installed at the bottom of the medicine cup 4 and is electrically connected to the control board 61. In this embodiment, the medicine cup 4 and the ultrasonic atomizing plate 5 can be separated from the nebulizer body 1 for cleaning and disinfection. Specifically, refer to... Figures 5 to 7 The bottom of the medicine cup 4 is provided with an annular groove 44, which is used to hold the ultrasonic atomizing plate 5 in place.

(Reference) Figure 7The medicine cup 4 includes a first opening 41, a second opening 42, and several spaced-apart blocking strips 43. The first opening 41 and the second opening 42 are respectively connected to the mask connection port 11 and the oxygen cylinder connection port 12. The blocking strips 43 curve upward from the bottom of the first opening 41 to the center of the medicine cup 4. The diameter of the atomized particles directly affects the drug deposition location. The effective atomized particle diameter should be 0.5~10μm, of which particles with a diameter of 5~10μm are mainly deposited in the oropharynx, particles with a diameter of 3~5μm are mainly deposited in the lungs, and 50%~60% of particles with a diameter <3μm are deposited in the alveoli. In the embodiments of this application, the blocking strips 43 block larger particles, causing them to flow back along the blocking strips 43 to the top of the ultrasonic atomizing plate 5 for re-atomization, improving the atomization effect and efficiency, so that the drug liquid is deposited in the lungs and the efficacy is guaranteed. Furthermore, the spaced-apart blocking strips 43 facilitate the dripping of the drug liquid into the medicine cup 4 through the intervals, eliminating the need to remove the medicine cup 4 for drug addition.

[0023] The emergency nebulizer proposed in this application uses an ultrasonic nebulizer 5 to atomize the liquid medicine and combines it with an oxygen cylinder 3 to supply oxygen, making it convenient for use in outdoor emergency rescue scenarios. The oxygen cylinder 3 is easy to install and has good portability. In addition, a blocking strip 43 is set in the medicine cup 4 to improve the atomization effect. It solves the problems of complex nebulization oxygen supply devices, poor portability, and uneven atomization of liquid medicine particles affecting the drug deposition position and efficacy in outdoor emergency rescue scenarios.

[0024] In a specific embodiment, it also includes an extension tube 7 and an elastic strap 8, with the extension tube 7 installed between the mask connection port 11 and the breathing mask 2. Specifically, refer to... Figure 4 and Figure 8 One end of the extension tube 7 is provided with a second protrusion 71, for reference. Figure 4 A U-shaped connecting part 111 is provided on the inner wall of the mask connection port 11 facing outward. A groove 112 is provided on the side of the U-shaped connecting part 111. When one end of the extension tube 7 is in the U-shaped connecting part 111, the second protrusion 71 is engaged in the groove 112 to fix one end of the extension tube 7 in the mask connection port 11. Figure 8 The other end of the extension tube 7 is fixedly connected to the breathing mask 2. (Reference) Figure 3 and Figure 8The other end of the extension tube 7 is provided with a buckle 72, and the outer wall of the mask connection port 11 is provided with a first protrusion 113. The buckle 72 can be fastened to the first protrusion 113 to fix the extension tube 7 to the storage position. The extension tube 7 is stored in the mask connection port 11. The extension tube 7 can be stored and extended to meet various usage scenarios and adapt to the patient's sitting, semi-sitting, or lying position. It ensures that the liquid medicine is in the medicine cup 4 and is nebulized by the ultrasonic nebulizer 5, ensuring the nebulization effect of the ultrasonic nebulizer 5 on the liquid medicine. The two ends of the elastic strap 8 are fixed to the breathing mask 2 and are sleeved on the side of the breathing mask 2 connected to the extension tube 7. The elastic strap 8 can be pulled out from the breathing mask 2 and sleeved on the patient's head to fix the position of the breathing mask 2 on the patient's face.

[0025] In a specific embodiment, refer to Figure 5 and Figure 6 The nebulizer body 1 also includes an oxygen cylinder mounting part 16 and an air inlet valve 17. The oxygen cylinder mounting part 16 is located below the oxygen cylinder connection port 12. A spring 161 is provided on the bottom surface of the oxygen cylinder mounting part 16. When the oxygen cylinder 3 is installed in the oxygen cylinder mounting part 16 and connected to the oxygen cylinder connection port 12, the spring 161 provides elastic force to the oxygen cylinder 3 toward the oxygen cylinder connection port 12 to press the air supply end of the oxygen cylinder 3 to supply air. In the embodiments of this application, the oxygen cylinder 3 used is the oxygen cylinder 3 commonly used in the prior art. The air inlet valve 17 is installed in the middle of the oxygen cylinder connection port 12. When the patient needs to receive nebulized medication and oxygen supply in synergy for treatment, the air inlet valve 17 is opened, and the air supply port of the oxygen cylinder 3 is connected to the inside of the medicine cup 4 through the oxygen cylinder connection port 12. When the patient only needs to receive nebulized medication, the air inlet valve 17 can be closed. Specifically, the oxygen cylinder mounting part 16 includes a first housing 162 and a second housing 163. One side of the first housing 162 is hinged to one side of the second housing 163. The other side of the first housing 162 and the other side of the second housing 163 are provided with multiple sets of magnetically attracted magnetic elements 164. When the magnetic elements 164 of the first housing 162 and the magnetic elements 164 of the second housing 163 are attracted, an installation space for the oxygen cylinder 3 is formed between the first housing 162 and the second housing 163 to fix the oxygen cylinder 3 and prevent the oxygen cylinder 3 from sliding out of the oxygen cylinder mounting part 16. A spring 161 is provided at the bottom of the first housing 162.

[0026] The working principle of an emergency atomizer proposed in this application will be further explained below.

[0027] Install the ultrasonic atomizing plate 5 into the annular groove 44 at the bottom of the medicine cup 4, then align the arc groove 45 of the medicine cup 4 with the guide part 15 of the atomizing bottle body, and install the medicine cup 4 inside the atomizing bottle body. Use the arc groove 45 and the guide part 15 to position the medicine cup 4 so that the first opening 41 and the second opening 42 of the medicine cup 4 can be connected to the mask connection port 11 and the oxygen cylinder connection port 12 respectively, so that the conductive contact 181 on the isolation plate 18 can contact the conductive contact 51 of the ultrasonic atomizing plate 5, making installation convenient.

[0028] When using the emergency nebulizer proposed in this application, open the top cover 13 of the nebulizer body 1, drip the medication for nebulization into the medicine cup 4, then close the top cover 13 and fasten it to the nebulizer body 1. In the area blocked by the blocking strips 43 above the ultrasonic nebulizer plate 5, the medication drips through the gaps between the blocking strips 43 onto the ultrasonic nebulizer plate 5. Fix the breathing mask 2 to the patient's face, turn on the nebulizer switch 14, and the control panel 61 controls the ultrasonic nebulizer plate 5 to atomize the medication in the medicine cup 4, breaking the surface tension of the medication into fine droplets. These droplets enter the patient's airway and lungs through the first opening 41, the extension tube 7, and the breathing mask 2. Larger atomized particles are blocked by the blocking strips 43 in the medicine cup 4 and flow back along the blocking strips 43 or drip from the blocking strips 43 onto the ultrasonic nebulizer plate 5 for re-nebulization, improving the nebulization effect and efficiency, and ensuring efficacy.

[0029] When a patient requires nebulized medication and oxygen supply for combined treatment, the second housing 163 is rotated to open, the bottom of the oxygen cylinder 3 is placed above the spring 161, and pressure is applied to the spring 161 so that the gas supply end of the oxygen cylinder 3 can be installed in the oxygen cylinder connection port 12. The second housing 163 is rotated so that the other sides of the first housing 162 and the second housing 163 are brought closer together, and the magnetic components 164 on the first housing 162 and the second housing 163 are magnetically attracted to fix the oxygen cylinder 3. The air inlet valve 17 is opened, and oxygen enters the medicine cup 4 through the gas supply end of the oxygen cylinder 3, the oxygen cylinder connection port 12, and the second opening 42, where it mixes with the droplets. The baffle strip 43 set in the medicine cup 4 helps the oxygen to mix evenly with the droplets in the medicine cup 4, improving the medication efficiency.

[0030] During treatment, the patient may adopt different body positions. When the patient is in a semi-sitting or lying position, the emergency nebulizer will tilt. The buckle 72 of the extension tube 7 is removed from the first protrusion 113 of the mask connection port 11. The extension tube 7 is used to extend the tubing according to the patient's body position, and the angle of the nebulizer body 1 is finely adjusted to ensure that the liquid medicine is above the ultrasonic nebulizing plate 5, thereby ensuring the nebulization effect and drug delivery efficiency.

[0031] The above embodiments are only used to further illustrate the technical solution of this utility model, but this utility model is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of the technical solution of this utility model.
