[0001] The utility model relates to the technical field of atomizing medicine storage cups, and more specifically to an integrated medical atomizing medicine storage cup. Background Art
[0002] Atomization inhalation therapy is one of the important treatment means for respiratory system related diseases and has been widely used clinically. During the process of a patient receiving atomization treatment, an aerosol mainly composed of tiny atomized liquid medicine particles ejected by an atomization device passes through a medical breathing mask and then is inhaled into the human respiratory tract through the mouth and nose. The liquid medicine particles are diffused to the entire respiratory system through the airflow generated during breathing and act on the corresponding pharmacological positions.
[0003] Atomization refers to the operation of dispersing a liquid into tiny droplets through a nozzle or with a high-speed airflow. Methods of liquid atomization include pressure atomization, rotary disk atomization, gas atomization, and acoustic wave atomization, etc., which mean that a liquid is turned into small droplets through a special device and sprayed out in a mist shape;
[0004] Existing traditional medical atomization devices are often relatively large in size, which greatly limits the movement range of users during use, and the manufacturing cost is also relatively expensive. Moreover, the miniaturization of equipment will also be one of the directions of atomization devices;
[0005] At the same time, the atomization generating device and the inhalation mask of traditional medical atomization treatment equipment have a relatively long channel, and finally there is a lot of liquid medicine residue;
[0006] If the atomization channel of the device after use is not thoroughly cleaned, it is easy to cause cross-infection or mixed contamination of different liquid medicines during its subsequent use. Content of the Utility Model

Specific embodiments
[0024] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. In addition, the forms of each structure described in the following embodiments are only examples. An integrated medical atomization medicine storage cup related to the present utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0025] Embodiment 1:
[0026] As Figures 1-7 shown, a structure of an integrated medical atomization medicine storage cup in an embodiment, an integrated medical atomization medicine storage cup includes a liquid medicine cylinder 1. The inside of the liquid medicine cylinder 1 is a liquid medicine storage chamber 9 for storing the liquid medicine required in the atomization treatment process. A first housing 2 is provided below the liquid medicine cylinder 1. A second housing 3 is installed on one side between the liquid medicine cylinder 1 and the first housing 2. The second housing 3 is composed of two semi-circular cylinders. A DC power socket 4 is installed inside the second housing 3. Buckles 14 and positioning posts 15 are installed around the bottom of the liquid medicine cylinder 1. Positioning holes 21 and clamping positions 22 are provided around the upper part of the inner wall of the first housing 2. The outer wall of the buckle 14 is clamped inside the clamping position 22, and the outer wall of the positioning post 15 is inserted inside the positioning hole 21. A piezoelectric ceramic atomization sheet 5 is provided inside between the liquid medicine cylinder 1 and the first housing 2. A cable 7 is electrically connected between the positive and negative poles of the DC power socket 4 and the piezoelectric ceramic atomization sheet 5. The positive and negative poles of the DC power socket 4 and the piezoelectric ceramic atomization sheet 5 are connected by the cable 7 to form an atomization assembly 8. A plurality of atomization holes with tiny apertures are provided at the center position of the piezoelectric ceramic atomization sheet 5. The atomization holes are regularly distributed in a circular shape near the center position of the piezoelectric ceramic atomization sheet 5. By using the clamping between the buckle 14 and the clamping position 22 and the insertion between the positioning post 15 and the positioning hole 21, it is convenient to assemble and fix the liquid medicine cylinder 1 and the first housing 2 together.
[0027] Embodiment 2:
[0028] As Figures 1-7As shown in the figure, a medicine liquid cylinder cover 11 is provided on the medicine liquid cylinder 1. An air vent hole 13 is opened in the middle of the medicine liquid cylinder cover 11. Medicine liquid volume scale lines 12 are engraved on the outer side of the medicine liquid cylinder 1. A mist spraying port 10 is opened at the lower part of the first housing 2. Since the medicine liquid directly contacts the piezoelectric ceramic atomizing sheet 5 in the medicine liquid cylinder 1 and then is directly sprayed out from the mist spraying port 10, the atomizing channel in the atomizing medicine storage cup is shortened.
[0029] Embodiment 3:
[0030] As Figures 1-7 shown in the figure, an upper sealing ring 61 is fixedly inlaid at the bottom end of the medicine liquid cylinder 1, and a lower sealing ring 62 is fixedly inlaid at the top end of the first housing 2. The upper sealing ring 61 is located at the contact surface between the piezoelectric ceramic atomizing sheet 5 and the bottom of the medicine liquid cylinder 1, and the lower sealing ring 62 is located at the contact surface between the piezoelectric ceramic atomizing sheet 5 and the inside of the first housing 2. When the medicine liquid cylinder 1 and the first housing 2 are installed, the upper sealing ring 61 and the lower sealing ring 62 are pressed tightly to prevent the leakage of the medicine liquid during the use of the product.
[0031] To sum up, as Figures 1-7 shown in the figure, during the use of this integrated medical atomizing medicine storage cup, open the medicine liquid cylinder cover 11, add the medicine liquid for atomizing treatment into the medicine liquid cavity 9 of the medicine liquid cylinder 1, and quantify the added medicine liquid according to the medicine liquid volume scale lines 12 on the side wall. After the medicine liquid is filled, tighten the medicine liquid cylinder cover 11. Since the bottom of the medicine liquid cavity 9 is the piezoelectric ceramic atomizing sheet 5, and the upper sealing ring 61 will effectively prevent the medicine liquid from leaking out from the contact surface between the medicine liquid cylinder 1 and the piezoelectric ceramic atomizing sheet 5 after being assembled and pressed tightly, the medicine liquid stored in the medicine liquid cylinder 1 will directly contact the atomizing holes at the center position of the piezoelectric ceramic atomizing sheet 5 due to the action of gravity. Connect the power supply to this utility model through the DC power socket 4, and the current is conducted to the piezoelectric ceramic atomizing sheet 5 through the cable 7, so that the atomizing assembly 8 can operate.
[0032] More specifically, after the atomizing assembly 8 is powered on, the annular piezoelectric ceramic of the piezoelectric ceramic atomizing sheet 5 is attached to a microporous mesh sheet to form the key element for ultrasonic atomization. The radial expansion and contraction vibration of the annular piezoelectric ceramic drives the axial vibration of the microporous mesh sheet, and then the microporous mesh sheet absorbs the liquid in the medicine liquid cylinder 1 and sprays it out through the micropores. Since there are many micropores and the pore diameters are very small (about 5 - 10 microns), the tiny liquid droplets sieved out by the microporous mesh form a liquid mist and are sprayed out from the mist spraying port 10. This atomizing method is not the atomization generated by the traditional vibration tearing, so this atomizing method is different from other ultrasonic atomizing methods. Its atomizing particle size has nothing to do with the ultrasonic frequency and is only related to the pore diameter of the micropores. The atomizing particle size is basically close to the pore diameter, which is convenient for manufacturing a smaller atomizing particle size so that the atomized medicine liquid can be more efficiently absorbed by the respiratory tract.
[0033] The atomized liquid medicine ejected from the atomizing ejection port 10 at the lower part of the first housing 2 can directly enter the buffer chamber of the breathing mask matching with the present utility model, be mixed with the inhaled air to form an aerosol, and then be directly inhaled by the human body. Since the contact surface between the piezoelectric ceramic atomizing sheet 5 and the first housing 2 is tightly pressed and sealed by the lower sealing ring 62, it can effectively prevent the atomized liquid medicine particles from diffusing into the interior of the structure of the present utility model.
[0034] Due to the distribution of the overall vertical working structure of the present utility model, the residual amount of the liquid medicine can be reduced to the greatest extent. Its overall streamlined structure reduces the manufacturing cost to the greatest extent. At the same time, the small volume can be directly installed on the matching atomizing mask, reducing the restriction on the user's activities due to the product volume.
[0035] The example of the present utility model especially refers to a liquid medicine atomizing device required for atomizing treatment of respiratory-related diseases, and can be a disposable product for single-patient use. A single patient only uses its corresponding atomizing medicine storage cup. After the patient finishes the atomizing treatment stage, the atomizing medicine storage cup can be discarded, but the present utility model is not limited thereto.
[0036] The technical solution of the example described in the present utility model simplifies and reduces the volume of the product to the greatest extent. The optimization of the liquid medicine storage and atomizing passage structure greatly improves the problem of liquid medicine residue. At the same time, the streamlined structure reduces the manufacturing cost of the product of the present utility model to a very low level. It can be a kind of disposable-like product for single-patient use. A single patient only uses its corresponding atomizing medicine storage cup. After the patient finishes the atomizing treatment stage, the atomizing medicine storage cup can be discarded, fundamentally avoiding the problems of cross-infection or mixed pollution of different liquid medicines caused by incomplete disinfection.
[0037] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, and can also be the communication inside two components.
