Base of mouth-nose aerosol dosing device

Abstract

According to the mouth and nose aerosol dosing device base, in the working process of the mouth and nose aerosol dosing device base, an output pipe of external aerosol is inserted into the insertion opening. Medicament is input into the atomizing cylinder of the dosing device by pressing a quantitative aerosol button on the external aerosol. In the process, a user inhales at the output end of an atomizing cylinder of an external dosing device, external air enters the four hollow spiral air inlet blocks through the four air inlets and enters the atomizing cylinder of the external dosing device through the four suction inlets, and due to the fact that the air suction direction of the suction inlets is tangent to the inserting pipe, the air suction direction of the suction inlets is tangent to the inserting pipe. Therefore, the spiral airflow can be formed in the atomizing cylinder of the external dosing device, and the spiral airflow can uniformly and fully scatter the medicament in the atomizing cylinder of the external dosing device, so that the medicament can be conveniently absorbed by a human body. And the square inserting opening is combined with the arc-shaped clamping bulges, so that aerosol output pipes with different sizes can be adapted, and the application range is wide.

Description

Technical Field

[0001] The utility model relates to the field of oral and nasal aerosol dispensers, in particular to a base of an oral and nasal aerosol dispenser. Background Art

[0002] Oral and nasal aerosol applicators are suitable for treating respiratory diseases such as chronic bronchitis, tuberculosis, pneumonia, asthma, emphysema, viral airway infections, bronchiectasis, bronchial muscle obstruction, pharyngitis, and strep throat in children and the elderly. The subepithelial layer of the nasal and oral mucosa is rich in capillaries and lymphatic capillaries, making them more receptive to foreign drugs than skin and muscle. They rapidly deliver drugs to the circulatory and lymphatic systems, and can deliver drugs to the cerebrospinal fluid within minutes. Oral and nasal aerosol applicators are a medical device and drug delivery method developed specifically to take advantage of these characteristics of the human oral and nasal cavities. Using the principles of a nebulizer, an oral and nasal aerosol applicator converts the drug into a mist or powder that is easily absorbed and digested by the human body before administration to the patient, ensuring optimal, fastest, and maximum drug absorption.

[0003] However, conventional oronasal aerosol dispensers, such as the one disclosed in patent application number CN202221779971.7, titled "Oronasal Aerosol Dispenser," require that the medication enter the dispenser from the bottom and be discharged from the top discharge nozzle. However, the insertion hole at the bottom of the dispenser can only accommodate aerosol delivery tubes of a single size, limiting its scope of use. Utility Model Content

[0004] Based on this, it is necessary to provide an oral and nasal aerosol dispenser base to address the technical problem that the insertion dosing hole opened at the bottom of the traditional dispenser can only adapt to aerosol output tubes of a single size and has a narrow range of use.

[0005] An oronasal aerosol dispenser base, comprising: a support base, an insertion tube, four hollow spiral air inlet blocks and a plurality of connecting ribs;

[0006] The support seat is a hollow cylindrical structure with one end open, and the insertion tube is a circular tube; the insertion tube is partially accommodated in the support seat, and one end of the insertion tube is connected to the inner wall of the middle area of ​​the bottom of the support seat; the part of the bottom of the support seat that is accommodated in the insertion tube is a soft receiving plate; the middle area of ​​the soft receiving plate is provided with an insertion opening, the insertion opening is a square hole, and a number of arc-shaped positioning protrusions are evenly arranged around the insertion opening;

[0007] The four hollow spiral air intake blocks are partially accommodated in the support seat, and the four hollow spiral air intake blocks are circumferentially arranged on the periphery of the insertion tube and connected to the insertion tube; four air inlets are evenly opened on the outer wall of the bottom of the support seat, and each of the air inlets is connected to a hollow spiral air intake block, and a suction port is opened on the hollow spiral air intake block, and the suction direction of the suction port is tangent to the insertion tube; an insertion groove is formed between each hollow spiral air intake block and the side wall of the support seat;

[0008] Each of the connecting ribs is arranged on the outer wall of the bottom of the support seat, and the support seat is connected to the insertion tube through each of the connecting ribs.

[0009] In one embodiment, the insertion tube and the support seat are integrally formed.

[0013] In one embodiment, each of the hollow spiral air inlet blocks is integrally formed with the support seat.

[0014] In one embodiment, each of the hollow spiral air inlet blocks is integrally formed with the insertion tube.

[0015] In one embodiment, each of the connecting ribs is integrally formed with the insertion tube.

[0016] In one embodiment, each of the connecting ribs is integrally formed with the support seat.

[0017] In one embodiment, the connecting rib is a rectangular parallelepiped structure.

[0018] During operation, the oral and nasal aerosol dispenser base is installed on the bottom of the external dispenser atomizer barrel, so that the bottom of the dispenser atomizer barrel is inserted into the insertion groove, so that the insertion tube and the four hollow spiral air inlet blocks are all accommodated in the bottom of the dispenser atomizer barrel. The output tube of the external aerosol is inserted into the insertion port. The medicine is input into the dispenser atomizer barrel by pressing the quantitative aerosol button on the external aerosol. In this process, the user inhales at the output end of the external dispenser atomizer barrel, and the outside air enters the four hollow spiral air inlet blocks through the four air inlets, and enters the external dispenser atomizer barrel through the four suction ports. Because the suction direction of the suction port is tangent to the insertion tube, a spiral airflow will be generated in the external dispenser atomizer barrel.

[0029] Please also refer to Figures 1 to 5 The utility model provides an oronasal aerosol dispenser base 10, which includes: a support base 100, an insertion tube 200, four hollow spiral air inlet blocks 300 and a plurality of connecting ribs 400.

[0030] The support seat 100 is a hollow cylindrical structure with one end open, and the insertion tube 200 is a circular tube. The insertion tube 200 is partially accommodated in the support seat 100, and one end of the insertion tube 200 is connected to the inner wall of the middle area of ​​the bottom of the support seat 100. In this embodiment, the insertion tube 200 and the support seat 100 are integrally formed. The part of the bottom of the support seat 100 that is accommodated in the insertion tube 200 is a soft receiving plate 110. In this embodiment, the soft receiving plate 110 is a TPE plate. In another embodiment, the soft receiving plate 110 is a soft silicone plate. The middle area of ​​the soft receiving plate 110 is provided with an insertion port 101, which is a square hole, and a number of arc-shaped positioning protrusions 111 are evenly arranged around the insertion port 101.
