Description

Technical Field

[0001] The present invention relates to the technical field of sprayers, and more particularly to a dual-power nasal spray delivery device. Background Art

[0002] Nowadays, spray technology is widely used in the pharmaceutical industry. Using spray devices to spray various medicines on affected areas such as the mouth, nasal cavity and skin surface has a great effect on the absorption and efficacy of the medicines. The comfort and efficacy of the spray device products are crucial, especially the nasal spray device. Medically proven, daily nasal cleaning can effectively relieve various rhinitis symptoms such as nasal congestion and runny nose, and can reduce the invasion of bacteria, allergens and other substances into the nasal cavity, thereby improving one's own respiratory immunity.

[0003] Existing nasal spray delivery devices on the market are designed similar to perfume bottles. Although some devices have very long nozzles that can reach into the nasal cavity, due to the complex structure of the nasal cavity, no matter how the nozzle shape is changed, it cannot deliver the drug very deep. In addition, if the nozzle is inserted too deep, it will not only cause discomfort to the patient, but also the patient will instinctively resist inserting a foreign object very deep into the nasal cavity.

[0004] To deliver medication deep into the nasal cavity, existing nasal spray delivery devices typically utilize an extended nozzle. During use, the nozzle is inserted into the nasal cavity. Once the nozzle reaches its intended location, the spray button 600 is pressed. The medication is deposited within the nasal cavity within the nozzle's reach. However, the complex shape of the nasal cavity means that the sprayed medication can only be deposited near the nozzle, failing to reach deeper, more distant lesions. The reach of the medication spray is entirely dependent on the nozzle's reach; medication cannot reach areas beyond the nozzle's reach. Summary of the Invention

[0032] Furthermore, the hollow semi-enclosed structure of the button 600 is provided with reinforcing ribs near the closed portion to enhance the strength of the button 600 .

[0033] In a preferred embodiment of the present invention, considering how the patient can press the button 600 with the least effort, the upper portion of the button 600 protrudes from the housing 100, the lower portion is flush with the housing 100, and the pressing portion is the protruding portion.

[0034] Furthermore, a pressing protrusion 605 is provided in the middle of the protruding portion, and pressing at this position can save the patient the most effort.

[0035] Furthermore, the spray assembly 707 has a structure similar to a perfume bottle, and the medicine is sprayed out by pressing the spray head 700 and the medicine bottle cap 800.

[0036] Working principle:

[0037] When the button 600 is not pressed, the spring pushes the spray head 700 and the housing 100, pressing the first sealing ring 300 tightly, so that the entire airway from the mouthpiece 400 to the nosepiece 900 is completely sealed;

[0038] When the button 600 is pressed, the button 600 pushes the medicine bottle cap 800 to move upward, and the spray head 700 and the first sealing ring 300 also move upward. At this time, a gap is formed between the first sealing ring 300 and the housing 100, and the air flow channel 706 is opened. At this time, the mounting structure 704 of the spray head 700 contacts the first step 103 of the housing 100, preventing the spray head 700 from moving further upward. The opening of the air flow channel 706 and the spraying are timed. After pressing the button 600, the button 600 pushes the spray head 700 to move a small distance upward, and the air channel is opened. Continue to press the button 600, and the lower part of the spray head 700 contacts the stop structure 702 of the housing 100, and then the spraying action will be performed.

[0039] That is: blow air first, the airway is not opened at the beginning, and an air pressure will be formed in the device; then press the button 600, the airway is opened, and the airflow comes first; continue to press the button 600, and the spray is sprayed out; here follows the timing of airflow first and spray later.

[0040] It should be noted that pressing the button 600 is a continuous action and there is no need to deliberately wait for the air flow to pass through first.

[0041] Further pressing the button 600 compresses the spray assembly 707 and sprays the medicine.

[0042] How to do it:

[0043] 1. Without pressing the button 600, blow air into the mouthpiece 400, the airflow will be completely closed, and air pressure will be generated in the airflow channel 706 due to the mouth blowing;

[0044] 2. Continue blowing and press the button 600 to open the airflow channel 706 between the first sealing ring 300 and the housing, allowing air to flow through.

[0045] 3. Continue blowing and pressing the button 600 to compress the spray assembly 707 and spray the medicine. The airflow will accelerate the medicine spray sprayed by the spray assembly 707 and deliver the medicine spray to a farther location.

[0046] 4. After use, stop blowing, release the button 600, and the spring pushes the spray assembly 707 downward to complete the reset.

At this time, a gap is formed between the first sealing ring 300 and the housing 100, and the air flow channel 706 is opened. At this time, the mounting structure 704 of the spray head 700 contacts the first step 103 of the housing 100, preventing the spray head 700 from moving further upward. The opening of the air flow channel 706 and the spraying are timed. After pressing the button 600, the button 600 pushes the spray head 700 to move a small distance upward, and the air channel is opened. Continue to press the button 600, and the lower part of the spray head 700 contacts the stop structure 702 of the housing 100, and then the spraying action will be performed.

[0091] That is: blow air first, the airway is not opened at the beginning, and an air pressure will be formed in the device; then press the button 600, the airway is opened, and the airflow comes first; continue to press the button 600, and the spray is sprayed out; here follows the timing of airflow first and spray later.

[0092] It should be noted that pressing the button 600 is a continuous action and there is no need to deliberately wait for the air flow to pass through first.

[0093] Further pressing the button 600 compresses the spray assembly 707 and sprays the medicine.

[0094] How to do it:

[0095] 1. Without pressing the button 600, blow air into the mouthpiece 400, the airflow will be completely closed, and air pressure will be generated in the airflow channel 706 due to the mouth blowing;

[0096] 2. Continue blowing and press the button 600 to open the airflow channel 706 between the first sealing ring 300 and the housing, allowing air to flow through.

[0097] 3. Continue blowing and pressing the button 600 to compress the spray assembly 707 and spray the medicine. The airflow will accelerate the medicine spray sprayed by the spray assembly 707 and deliver the medicine spray to a farther location.

[0098] 4. After use, stop blowing, release the button 600, and the spring pushes the spray assembly 707 downward to complete the reset.
