DETAILED DESCRIPTION

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0027] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see attached Figure 1 -Attached Figure 7The present invention discloses a drug dispensing device based on photocatalysis and antibacterial, comprising a base 1, wherein the top surface of the base 1 is provided with two limiting grooves, and a liquid storage tank 2 and an atomizing tank 3 are respectively placed in the two limiting grooves, a copper oxide cylinder 4 is clamped on the inner bottom surface of the atomizing tank 3, and an infusion tube 5 is connected through the copper oxide cylinder 4 and the liquid storage tank 2, a sealing cover 6 is detachably installed on the top surface of the atomizing tank 3, a bracket 8 is fixedly installed at the center of the top surface of the sealing cover 6 through a supporting rod 7, an electric push rod 9 is fixedly installed on the bottom surface of the bracket 8, a blocking sheet 10 is fixedly installed on the output end of the electric push rod 9, an LED lamp 11 is fixedly installed on the inner wall of the sealing cover 6, a connector 12 is installed through the top surface of the atomizing tank 3, and a gas delivery hose 13 is sleeved on the surface of the connector 12.

[0029] In the first embodiment, the diameter of the blocking sheet 10 is the same as the diameter of the copper oxide cylinder 4, and the top surface of the copper oxide cylinder 4 is lower than the top surface of the connector 12;

[0030] A battery is disposed on the top surface of the sealing cover 6, the battery is electrically connected to the LED lamp 11, and a handle is installed on the top surface of the sealing cover 6;

[0031] A reflective film is fixedly mounted on the inner wall of the atomizing tank 3, and the LED lamps 11 are arranged in a circle;

[0032] Specifically, in the respiratory ward of the hospital, the medical staff prepares to use the drug delivery device to perform aerosol treatment on a patient suffering from respiratory tract infection. First, confirm that the liquid storage tank 2 has been filled with an appropriate amount of aerosol medicine according to the doctor's instructions, and that all components are well connected. When the treatment begins, the electric push rod 9 is started, and the output end of the electric push rod 9 drives the blocking piece 10 to move upward rapidly until the blocking piece 10 no longer blocks the connector 12. At this time, the aerosol liquid in the liquid storage tank 2 flows into the aerosol tank 3 through the infusion tube 5 under the action of gravity or other pressure, and after aerosol treatment, smoothly passes through the connector 12 into the air delivery hose 13. During the entire treatment process, the aerosol liquid is continuously and stably delivered to the patient's respiratory tract;

[0033] When the treatment is over, the medical staff starts the electric push rod 9 again to move the blocking plate 10 downward until it completely covers the top opening of the copper oxide cylinder 4, and then turns on the LED lamp 11. The light emitted by the LED lamp 11 is evenly irradiated on the copper oxide cylinder 4. Since copper oxide has photocatalytic properties, it can produce active substances with strong oxidizing properties under light conditions. These active substances can effectively kill various microorganisms remaining in the atomization tank 3, such as bacteria, viruses and fungi. After a period of irradiation, the microbial contamination in the atomization tank 3 is significantly eliminated, making it fully prepared for the next use, ensuring the safety and hygiene of different patients when using it, and effectively preventing the occurrence of cross infection.

[0034] In the second embodiment, an electrically controlled valve 14 is provided inside the infusion tube 5, and a top cover 15 is detachably installed on the top surface of the liquid storage tank 2;

[0035] A weight sensor is installed in the limit groove below the liquid storage tank 2, and a display screen 16 is fixedly installed on the front of the base 1, and the display screen 16 and the weight sensor are linearly connected;

[0036] A mounting seat 17 is fixedly mounted on the top surface of the base 1, a damping rod 18 is rotatably connected to the top surface of the mounting seat 17, a telescopic rod 19 is fixedly mounted on the top surface of the damping rod 18, and a clamping block 20 is fixedly mounted on the top surface of the telescopic rod 19;

[0037] The output end of the gas delivery hose 13 is detachably mounted with a suction nozzle 21, and a storage box 23 is mounted on the top surface of the base 1. Spare gas delivery hoses 13 and suction nozzles 21 of different models are placed inside the storage box 23;

[0038] Specifically, in a home care scenario, an elderly person suffering from chronic bronchitis needs to use the drug delivery device for daily atomization treatment. The elderly person sits on a comfortable chair, and the family members help adjust the position of the drug delivery device. First, by rotating the damping rod 18 on the mounting seat 17, the horizontal angle of the nozzle 21 at the output end of the gas hose 13 can be easily changed. Then, the telescopic rod 19 is stretched or retracted to accurately adjust the height of the nozzle 21. For example, if the elderly person feels that it is more comfortable to use the nozzle 21 while lying flat, the family members rotate the damping rod 18 to a suitable angle and extend the telescopic rod 19 so that the nozzle 21 can be accurately placed at a suitable position above the elderly person's mouth and nose.

[0039] During the adjustment process, the nozzle 21 can stably maintain the set position and angle. When the elderly person needs to slightly change his posture during treatment, the nozzle 21 can still fit the mouth and nose tightly, and the medicine can be continuously and accurately delivered to the diseased part of the respiratory tract. This flexible adjustment function not only improves the comfort of the elderly in using the drug delivery device, reduces the discomfort such as choking caused by improper position of the nozzle 21, but also ensures that the medicine can fully exert its therapeutic effect, improves the effectiveness and compliance of the treatment, and enables the elderly to carry out home nebulization treatment more conveniently and comfortably.

[0040] In the third embodiment, a buffer mechanism 22 is provided inside the limiting groove below the atomizer tank 3. The buffer mechanism 22 includes a buffer pad 221, a buffer rod 222, a buffer spring 223 and a bottom plate 224. The top surface of the buffer pad 221 is in contact with the bottom surface of the atomizer tank 3. The two ends of the buffer rod 222 and the buffer spring 223 are fixedly connected to the bottom surface of the buffer pad 221 and the top surface of the bottom plate 224 respectively.

[0041] Specifically, in the daily diagnosis and treatment process of a small clinic, medical staff frequently use the drug delivery device to perform aerosol treatment on different patients. During each use, the aerosol can 3 is subjected to various degrees of impact, such as collision with a desktop or other objects when placing or taking it, or shaking due to internal pressure changes and mechanical vibrations during the aerosol process;

[0042] Since a buffer mechanism 22 is provided in the limiting groove below the atomizer tank 3, when the atomizer tank 3 is impacted, the buffer pad 221 first contacts the bottom surface of the atomizer tank 3, and the buffer pad 221 evenly disperses the impact force. At the same time, the buffer rod 222 will compress the buffer spring 223 downward with the impact force. The buffer spring 223 absorbs and transforms the impact force through its own elastic deformation, thereby preventing the impact force from being directly transmitted to the atomizer tank 3 and its internal precision components. For example, in a hurried operation, the medical staff accidentally knocked over the base 1 on which the atomizer tank 3 was placed. However, due to the action of the buffer mechanism 22, the copper oxide cylinder 4, the infusion tube 5 and other components inside the atomizer tank 3 were not damaged, and the atomization process was not significantly disturbed, so the atomization and drug delivery can still be carried out stably.

[0043] Working principle:

[0044] First, the liquid storage tank 2 and the atomization tank 3 are fixed by the limit groove on the base 1, and the liquid medicine in the liquid storage tank 2 flows into the copper oxide cylinder 4 in the atomization tank 3 through the infusion tube 5. When the drug delivery device needs to be used, the electric push rod 9 drives the blocking plate 10 to move away, allowing the atomized liquid to enter the air delivery hose 13 through the connector 12, and finally output to the patient through the suction nozzle 21. When not in use, the electric push rod 9 makes the blocking plate 10 cover the copper oxide cylinder 4, and at the same time the LED lamp 11 is started to irradiate the surface of the copper oxide cylinder 4, and the photocatalytic effect is used to decompose and produce bactericidal substances, which effectively kills the microorganisms in the atomization tank 3. Biological, to ensure health and safety. In addition, the drug delivery device realizes the free adjustment of the height and angle of the suction nozzle 21 through the design of the mounting seat 17, the damping rod 18, the telescopic rod 19 and the block 20, thereby improving the flexibility and accuracy of treatment. At the same time, the buffer mechanism 22 under the nebulizer tank 3, including the buffer pad 221, the buffer rod 222, the buffer spring 223 and the base plate 224, effectively absorbs and disperses the impact and vibration generated during use, protects the nebulizer tank 3 and its internal components, and ensures the stability and reliability of the nebulization process. At this point, the entire workflow is completed.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.

[0048] It is apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and the changes still fall within the protection scope of the invention.
