Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to an automatic liquid medicine atomization cup. Background Art
[0002] The drug nebulizer cup is a medical device used to convert drug liquid into fine droplets so that patients can be treated by inhalation. It usually consists of a container, a nozzle and an air flow channel. The drug liquid is sprayed out of the nozzle through a high-speed airflow to form mist particles for patients to inhale. This device is widely used in the treatment of respiratory diseases such as asthma, chronic obstructive pulmonary disease, etc., by delivering the drug directly to the lesion site to improve the treatment effect.
[0003] The medicine nebulizer cup may have some defects or shortcomings during use. Due to the influence of factors such as airflow shape, pressure, and medicine concentration, the size of the droplets may be uneven, which may cause some droplets to be too large and unable to enter the deep lungs, thus affecting the treatment effect. The nebulization effect is low, and sometimes a larger airflow is required to nebulize the medicine. An airflow that is too small will cause the volume of the droplets after nebulization to be too large, reducing the treatment effect and prolonging the treatment time. The medicine nebulizer cup may generate loud noise during use, which may interfere with the patient's treatment experience, especially for noise-sensitive patients. Utility Model Content
[0004] (I) Technical problems solved: In view of the shortcomings of the prior art, the utility model provides an automatic atomization cup for liquid medicine, which has the advantages of uniform atomization, small required air flow and low noise, and solves the problems of slow efficiency and uneven atomization in the process of liquid medicine atomization.
[0005] (ii) Technical solution: In order to achieve the above-mentioned purpose of uniform atomization, small required airflow and low noise, the utility model provides the following technical solution: an automatic liquid medicine atomization cup, comprising an atomization cup body, a medicine suction port, a liquid medicine pool, an airflow injection port and a lid, the medicine suction port being arranged on one side of the atomization cup body, the liquid medicine pool being arranged below the atomization cup body, the airflow injection port passing through the liquid medicine pool and entering into the atomization cup body, the airflow injection port being connected to the high-pressure airflow through an air pipe, the lid being arranged above the atomization cup body, and an airflow column being connected below the lid, a barrier for breaking up the liquid medicine being arranged on the side of the airflow column, and a vortex ring generating cavity being arranged below, the gas introduced into the airflow injection port flows into the vortex ring generating cavity from the center, the vortex ring generating cavity is provided with only one downward opening, and is circular in shape, the opening size is smaller than the overall size of the vortex ring generating cavity, after the airflow flows into the vortex ring generating cavity, it collides with the inner wall and flows out from the edge.
[0006] Preferably, a mesh is provided on the inner wall of the atomizer cup above the medicine liquid pool. The mesh can adhere to the airflow outside the vortex ring very well, thereby improving the quality and stability of the vortex ring. When the fluid is treated with the mesh, the vortex ring has a more regular and stable structure and stronger targeting, and its direction is easier to control. The presence of the mesh makes the vortex ring more stable, and the mesh can absorb larger droplets remaining in the vortex ring, so that the droplets converge and flow back into the medicine liquid pool.
[0007] Preferably, an annular filter is provided between the mesh cloth and the medicine inhalation port, the inner side of the filter is in contact with the airflow column, and the fine mesh holes of the filter will destroy the larger vortex structure in the airflow, thereby reducing the turbulence of the fluid. By reducing the turbulence, the patient will have a more comfortable treatment process when inhaling, and the pores of the filter can break up or block large droplets in the vortex, thereby preventing the patient from inhaling larger droplets during the process of inhaling the medicine.
[0008] Preferably, the pore size of the filter screen near the drug inhalation port is smaller than the pore size far from the drug inhalation port.
[0009] Preferably, the vortex ring generating cavity is spherical as a whole, and has rounded corners at the corners of the airflow column. The overall spherical shape of the cavity and the rounded corners effectively reduce the occurrence of turbulence and turbulence, making the gas flow more orderly. The overall spherical shape of the cavity will make the airflow flowing along the inner wall point to the middle of the opening when flowing out, which helps to form a strong rotational motion in the central area.
[0010] (III) Beneficial effects: Compared with the prior art, the utility model provides an automatic atomization cup for liquid medicine, which has the following beneficial effects:
[0011] 1. The automatic atomization cup for liquid medicine has an intermittent pulsed airflow introduced through the airflow injection port. After the airflow enters the body of the atomization cup, it rushes into the vortex ring generating cavity, then collides with the inner wall and flows to the side, and flows out from the periphery of the circular opening of the vortex ring generating cavity. Moreover, because the airflow injection port sprays airflow to the middle of the vortex ring generating cavity, the air pressure in the middle of the airflow flowing out of the circular opening is reduced, forming a collapse, and the outer airflow flows inward, the airflow rotates, forming a vortex ring, and the vortex ring flows downward. The flowing airflow attracts the liquid medicine in the liquid medicine pool. The high-speed rotation of the vortex ring causes the liquid medicine to be quickly decomposed into tiny droplets in a very short time. This rapid decomposition process ensures that the drug can be quickly and evenly distributed to the patient's respiratory tract. In the lungs, the rotating force generated by the vortex ring helps to form droplets of uniform size. This uniformity ensures that the drug particles are deposited more evenly in the lungs, thereby improving the therapeutic effect. Through the formation of the vortex ring, a good atomization effect can be achieved even at a lower air flow rate, which means that the nebulizer cup consumes less energy during operation, thereby reducing energy costs. The formation of the vortex ring makes the airflow inside the nebulizer cup smoother, reducing the friction with the cup wall, thereby reducing the generation of noise. Whether it is a high-viscosity or low-viscosity drug solution, the nebulizer cup based on the vortex ring principle can achieve effective atomization by adjusting the structure of the vortex ring and the airflow parameters. This flexibility enables the nebulizer cup to cope with a variety of different drugs and treatment needs.
[0012] 2. The automatic atomization cup of the liquid medicine is provided with a mesh on the inner wall of the atomization cup above the liquid medicine pool. The mesh can adhere to the airflow outside the vortex ring very well, improving the quality and stability of the vortex ring. When the fluid treated by the mesh forms a vortex ring, the structure of the vortex ring is more regular and stable, and the targeting is stronger, and the direction is easier to control. The existence of the mesh makes the vortex ring more stable and reduces the fluctuation and instability of the vortex ring, which is very important for applications that require precise control of the shape and position of the vortex ring. At the same time, the mesh can absorb the larger droplets remaining in the vortex ring, so that the droplets converge and flow back to the liquid medicine. In the pool, an annular filter is provided between the mesh and the medicine inhalation port, the inner side of the filter is fitted with the airflow column, and the fine mesh holes of the filter will destroy the larger vortex structure in the airflow, and this destructive effect helps to decompose the large vortex into smaller vortices, thereby reducing the turbulence of the fluid. The filter can make the fluid flow smoother and more uniform, and by reducing turbulence, the patient has a more comfortable treatment process when inhaling. At the same time, the pores of the filter can break up or block large droplets in the vortex, avoiding the patient from inhaling larger droplets during the process of inhaling the drug, causing damage to the respiratory tract and causing discomfort to the patient.

[0014] In the figure: 1, atomizer cup body; 11, medicine suction port; 12, medicine liquid pool; 13, air flow injection port; 14, cover; 15, filter; 141, vortex ring generating cavity; 142, air flow column; 151, mesh cloth. DETAILED DESCRIPTION
[0015] 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.
[0016] See also Figure 1 A liquid medicine automatic atomization cup comprises an atomization cup body 1, a medicine suction port 11, a liquid medicine pool 12, an air flow injection port 13 and a cover 14, wherein the medicine suction port 11 is arranged on one side of the atomization cup body 1, the liquid medicine pool 12 is arranged below the atomization cup body 1, the air flow injection port 13 passes through the liquid medicine pool 12 and enters the atomization cup body 1, the air flow injection port 13 is connected to the high-pressure air flow through an air pipe, the cover 14 is arranged above the atomization cup body 1, and an air flow column 142 is connected below the cover 14, a barrier (not shown) for breaking up the liquid medicine is arranged on the side of the air flow column 142, and a vortex ring generating cavity 141 is arranged below, the gas introduced by the air flow injection port 13 flows into the vortex ring generating cavity 141 from the center, and the vortex ring generating cavity 141 is formed by the air flow injection port 13. The generating cavity 141 is provided with only one downward opening, which is circular in shape. The size of the opening is smaller than the overall size of the vortex ring generating cavity 141. After the airflow flows into the vortex ring generating cavity 141, it collides with the inner wall and flows out from the edge. Moreover, because the airflow injection port 13 sprays airflow toward the middle of the vortex ring generating cavity 141, the air pressure in the middle of the airflow flowing out from the circular opening is reduced, forming a collapse. The outer airflow flows inward, the airflow rotates, and a vortex ring is formed. The vortex ring flows downward, and the flowing airflow attracts the medicine in the medicine pool 12. After the medicine is attracted by the negative pressure of the airflow, the medicine is crushed into droplets of different sizes due to the blocking effect of the high-speed rotating airflow and the obstacles set on the airflow column 142. The droplets are then carried upward by the airflow.
[0017] A mesh 151 is provided on the inner wall of the atomizer cup body 1 above the liquid medicine pool 12. The mesh 151 can adhere to the airflow outside the vortex ring very well, thereby improving the quality and stability of the vortex ring. When the fluid treated by the mesh 151 forms a vortex ring, the structure of the vortex ring is more regular and stable, and the targeting is stronger, and the direction is easier to control. The presence of the mesh makes the vortex ring more stable and reduces the fluctuation and instability of the vortex ring, which is crucial for applications that require precise control of the shape and position of the vortex ring. At the same time, the mesh 151 can absorb larger droplets remaining in the vortex ring, causing the droplets to converge and flow back into the liquid medicine pool 12.
[0018] An annular filter screen 15 is provided between the mesh cloth 151 and the medicine inhalation port 11, and the inner side of the filter screen 15 is fitted with the airflow column 142. The fine mesh holes of the filter screen 15 will destroy the larger vortex structure in the airflow. This destructive effect helps to decompose the large vortex into smaller vortices, thereby reducing the turbulence of the fluid. The filter screen 15 can make the fluid flow smoother and more uniform, and by reducing turbulence, the patient has a more comfortable treatment process when inhaling. At the same time, the pores of the filter screen 15 can break up or block large droplets in the vortex, thereby preventing the patient from inhaling larger droplets during the process of inhaling the medicine, causing damage to the respiratory tract and causing discomfort to the patient.
[0019] The pore size of the filter screen 15 near the medicine inhalation port 11 is smaller than the pore size far from the medicine inhalation port 11 , so that the droplets passing through the part near the medicine inhalation port 11 are smaller.
[0020] The vortex ring generating cavity 141 is spherical as a whole, and has rounded corners at the corners of the airflow column 142. The spherical shape and rounded corners of the cavity 141 effectively reduce the occurrence of turbulence and turbulence, making the gas flow more orderly and the formed vortex ring flow more stable. The cavity 141 is spherical as a whole, which will make the airflow flowing along the inner wall point to the middle of the opening when flowing out, which helps to form a strong rotational motion in the central area. This rotational motion is the key to the formation of vortex because it makes the fluid rotate around the central axis, thereby forming a vortex ring structure and improving the stability of the vortex ring.
[0021] Working principle: one end of the air pipe is connected to the compressor, and the other end is connected to the air flow injection port 13, and the gas is sprayed into the atomizer cup body 1, and the air flow introduced into the air flow injection port 13 is an intermittent pulse air flow. After the air flow enters the atomizer cup body 1, it rushes into the vortex ring generating cavity 141, then collides with the inner wall and flows to the side, and flows out from the circular opening around the vortex ring generating cavity 141. Because the air flow injection port 13 sprays air flow to the middle of the vortex ring generating cavity 141, the air pressure in the middle of the air flow flowing out of the circular opening is reduced, forming a collapse, and the outer air flow flows inward, the air flow rotates, forming a vortex ring, and the vortex ring flows downward. The flowing air flow attracts the medicine in the medicine pool 12. After the medicine is attracted by the negative pressure of the air flow, due to the high-speed rotating air flow and the air flow column 142 set The medicine liquid is crushed into droplets of different sizes due to the blocking effect of the obstruction, and then the droplets are carried upward by the airflow and pass through the filter 15. The larger droplets cannot pass through and condense on the filter 15 and fall back into the medicine liquid pool 12, or are affected by the airflow and pass through the filter 15, breaking themselves into smaller droplets again. The droplets suitable for human inhalation carried by the airflow pass through the filter 15 along with the vortex ring airflow. At the same time, when the vortex ring airflow passes through the filter 15, the fine mesh of the filter 15 will destroy the larger vortex structure in the airflow. This destructive effect helps to decompose the large vortex into smaller vortices, thereby reducing the turbulence of the fluid. The filter 15 can make the fluid flow smoother and more uniform. By reducing turbulence, the patient has a more comfortable treatment process when inhaling.
