Description

Technical Field

[0001] The invention relates to the technical field of medical atomizers, and in particular to an atomizer capable of adjusting the size of droplets. Background Art

[0002] In the medical field, the care of tracheotomy patients is extremely important. After tracheotomy, the patient's airway is directly connected to the outside world, and the natural humidification and filtering functions of the nasal cavity are lost, resulting in dry airway. In order to solve this problem, tracheotomy patients need to be humidified 24 hours a day to keep the airway moist. At present, although there are some humidification devices for tracheotomy patients on the market, most of them have the following problems:

[0003] On the one hand, it is difficult to accurately control the humidification amount with existing humidification devices. Since tracheotomy patients cannot tolerate excessive humidification, which can lead to serious complications such as pulmonary edema, a device that can accurately control the humidification amount is needed. However, existing humidification devices often cannot meet this requirement, and the humidification amount is difficult to adjust or the adjustment accuracy is not high.

[0004] On the other hand, existing humidification devices are insufficient in terms of portability and continuous use. Tracheotomy patients usually require long-term care, so a portable humidification device that can be used continuously for 24 hours is needed to facilitate the patient's daily activities and care. However, existing humidification devices are either large in size and inconvenient to carry, or have insufficient battery life and cannot meet the requirements of 24-hour continuous use.

DETAILED DESCRIPTION

[0033] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0034] Example

[0035] Reference Figure 1-3 , an atomizer with adjustable droplet size, comprising an outer shell tube 1, an upper end of the outer shell tube 1 is rotatably connected with an adjustment chamber 3, a lower end of the adjustment chamber 3 is installed with a threaded sleeve 2, and the threaded sleeve 2 is threadedly connected to the upper end of the outer shell tube 1, an upper end of the adjustment chamber 3 is inserted with an air guide tube 4, a rotating cylinder 5 is inserted on the air guide tube 4, a connecting tube 8 is vertically connected to the rotating cylinder 5, an atomizing nozzle 6 is plugged in the connecting tube 8, and a sliding sleeve 7 is installed outside the connecting tube 8 and the atomizing nozzle 6;

[0036] The outer shell barrel 1 includes an atomization bin 9 and a buffer bin 10, and the atomization bin 9 and the buffer bin 10 are connected by threads. An atomization tube 11 is inserted in the buffer bin 10, and the upper end of the atomization tube 11 is connected with the regulating bin 3. A plurality of connecting frames 14 are symmetrically installed on the inner top wall of the regulating bin 3. The lower ends of the plurality of connecting frames 14 are commonly connected with an air guide seat 13. An air guide hole 15 is opened on the air guide seat 13, and the air guide hole 15 is connected with the atomization tube 11. The lower end of the atomization tube 11 extends into the atomization bin 9 and is installed with a micro air compression pump.

[0037] When in use, the medicine and liquid to be atomized are placed in the atomization chamber 9, and then the atomizer is assembled. The micro air compressor pump works to compress the air and send it into the regulating chamber 3 through the atomization tube 11 and the air guide hole 15. The air passes through the lower end of the air guide tube 4 in the regulating chamber 3 and enters the rotating cylinder 5 and the connecting tube 8, and then enters the human body through the atomization nozzle 6.

[0038] refer to Figure 2-7 , an installation inner cylinder 16 is installed in the rotating cylinder 5, and the air guide tube 4 is located between the rotating cylinder 5 and the installation inner cylinder 16, a mist particle adjustment plate 19 is installed on the inner wall of the air guide tube 4, an adjustment plate 17 is installed at the lower end of the installation inner cylinder 16, and the adjustment plate 17 is located above the mist particle adjustment plate 19; the mist particle adjustment plate 19 is divided into a plurality of adjustment areas, each of which is evenly provided with a plurality of through holes 22 with different apertures, a fan-shaped corresponding hole 18 is provided on the adjustment plate 17, and the fan-shaped corresponding hole 18 corresponds to one of the adjustment areas, a plurality of limiting strips 21 are symmetrically provided on the upper end surface of the mist particle adjustment plate 19, and each adjustment area is located between two adjacent limiting strips 21, a plurality of limiting grooves 20 are symmetrically provided on the lower end surface of the adjustment plate 17, and each limiting strip 21 is clamped in the limiting groove 20 corresponding to the position;

[0039] An annular mounting groove 26 is provided on the inner side wall of the air guide tube 4, a limiting ring 33 is fixedly connected to the outer side wall of the inner tube 16, and the limiting ring 33 is located in the annular mounting groove 26, a mounting frame is installed on the inner top wall of the annular mounting groove 26, and a plurality of return springs 25 are installed between the mounting frame and the limiting ring 33. An annular mounting groove 26 is provided on the inner side wall of the air guide tube 4, a limiting ring 33 is fixedly connected to the outer side wall of the inner tube 16, and the limiting ring 33 is located in the annular mounting groove 26, a mounting frame is installed on the inner top wall of the annular mounting groove 26, and a plurality of return springs 25 are installed between the mounting frame and the limiting ring 33.

[0040] When the size of the mist droplets needs to be adjusted, the rotating drum 5 is rotated, and the inner drum 16 is installed to rotate accordingly, driving the adjustment plate 17 to rotate. Since the limit strip 21 on the mist particle adjustment plate 19 is clamped in the limit groove 20 on the lower end surface of the adjustment plate 17, the adjustment plate 17 rotates stably and can accurately correspond to different adjustment areas; when the fan-shaped corresponding hole 18 corresponds to different adjustment areas, the air passes through the through holes 22 with different apertures, thereby achieving the adjustment of the size of the mist droplets. For example, when the fan-shaped corresponding hole 18 corresponds to the through hole 22 with a smaller aperture, the generated mist droplets are smaller; when it corresponds to the through hole 22 with a larger aperture, the mist droplets are larger.

[0041] When the rotating drum 5 and the installation inner drum 16 rotate, the adjusting plate 17 is driven to rotate, and the adjusting plate 17 drives the limiting ring 33 fixedly connected thereto to rotate in the annular installation groove 26. During the rotation process, the limiting strip 21 is disengaged from the limiting groove 20, and the position of the limiting strip 21 remains fixed. The limiting strip 21 pushes the adjusting plate 17 to move upward in the vertical direction, so the installation inner drum 16 and the rotating drum 5 move upward accordingly, and the position of the air guide pipe 4 and the annular installation groove 26 remains fixed. Therefore, the distance between the limiting ring 33 and the mounting frame is shortened, and the reset spring 25 is compressed, and the rotating drum 5 continues to rotate until the fan-shaped corresponding hole 18 on the adjusting plate 17 corresponds to the position of the next adjustment area. At this time, the limiting strip 21 is again stuck in the limiting groove 20 , the reset spring 25 is reset, and the adjustment plate 17 and the mist particle adjustment plate 19 are against each other; the reset spring 25 plays a certain buffering and positioning role, ensuring that the relative position between the adjustment plate 17 and the mist particle adjustment plate 19 is stable, and at the same time provides a certain sense of resistance during rotation adjustment, so as to accurately adjust the droplet size; for patients with more sensitive respiratory tracts, smaller droplets can be selected to reduce irritation to the respiratory tract; and for patients who need to absorb drugs quickly, larger droplets can be selected to improve the absorption efficiency of the drugs; at the same time, different drugs may require droplets of different sizes to achieve the best therapeutic effect. This nebulizer with adjustable droplet size can be adjusted according to the characteristics of the drugs to improve the utilization rate and therapeutic effect of the drugs.

[0042] refer to Figure 1-2 and Figure 8-9 A fixing ring seat 32 is fixedly connected to the outer wall of the connecting tube 8, a wedge ring 31 is fixedly connected to the inner wall of the sliding sleeve 7, a locking spring 28 is installed between the fixing ring seat 32 and the wedge ring 31, a plurality of spherical grooves 12 are symmetrically provided on the outer wall of the atomizing nozzle 6, a plurality of spherical holes 29 are symmetrically provided on the connecting tube 8, a locking ball 30 is provided in each spherical hole 29, and each locking ball 30 is clamped in the spherical groove 12 corresponding to the position, and each locking ball 30 is against the inner wall of the wedge ring 31, a first sealing ring is installed on the side of the fixing ring seat 32 close to the wedge ring 31, and a second sealing ring is installed on the side of the wedge ring 31 close to the fixing ring seat 32.

[0043] When the atomizer nozzle 6 needs to be installed or replaced, the sliding sleeve 7 is pushed, and the wedge ring 31 compresses the locking spring 28 and moves toward the fixed ring seat 32. The inner wall of the wedge ring 31 no longer squeezes the locking ball 30, so that the locking ball 30 can be withdrawn from the spherical groove 12. At this time, the atomizer nozzle 6 can be inserted or removed. After the atomizer nozzle 6 is installed, the sliding sleeve 7 is loosened. Under the action of the locking spring 28, the wedge ring 31 is reset, squeezing the locking ball 30 to make it snap into the spherical groove 12, thereby fixing the atomizer nozzle 6; the first sealing ring and the second sealing ring between the fixed ring seat 32 and the wedge ring 31 play a sealing role to prevent gas leakage.
