Description

Oxygen atomizer for children

Technical Field

The utility model relates to an atomizer, and particularly discloses an oxygen atomizer for children.

Background

A children oxygen atomizer is a medical device commonly used in oxygen atomization inhalation therapy, and mainly comprises an atomizing cup, a cover body, an atomizing core, an air source pipe interface and an atomizing outlet. High-speed oxygen airflow is connected to the air source pipe interface to enable the liquid medicine to form a mist suspension, and then the mist suspension is inhaled into the respiratory tract along with respiration, so that the purpose of treatment is achieved.

Children's oxygen atomizer on the existing market, in the use, there is the liquid medicine foaming phenomenon in the atomizing cup, when the foam is more, can lead to blockking up the atomizing export, causes the fog to go out, makes the infant not inhale the fog.

Disclosure of Invention

The utility model aims to overcome the problems in the prior art and provide the children oxygen atomizer which can eliminate liquid medicine foam, so that a child patient can inhale mist more effectively and the aim of treatment is fulfilled.

The utility model is realized by the following steps: the utility model provides a children's oxygen atomizer, includes atomizing cup, atomizing core and lid, the bottom of atomizing cup is equipped with the air supply pipe connector mouth, upper portion one side of atomizing cup is equipped with the atomizing export, still includes fire fighting equipment, fire fighting equipment includes fixed column and bubble aggregation board, run through from top to bottom at the center of fixed column the fixed passage of fixed column, fixed passage fixes on the atomizing core, fixed passage with it runs through from top to bottom to be equipped with a plurality of between the lateral surface of fixed column the bubble fracture passageway of fixed column, the bubble aggregation board is the toper tube-shape that the upper shed diameter is less than the end opening diameter, the upper end of bubble aggregation board with the lower extreme of fixed column links to each other, the lower extreme of bubble aggregation board with be equipped with the clearance between the inner wall of atomizing cup.

The gap distance between the lower end of the bubble aggregation plate and the inner wall of the atomizing cup is 0.01-0.05 mm.

The inner diameter of the bubble bursting channel is 0.6-12 mu m.

The height of the fixing column is 60-100 mm.

The number of the bubble rupture channels is 36-60, and the bubbles are uniformly distributed in the side wall of the fixed column.

The beneficial effects of the utility model are: foam in the liquid medicine is gathered to the lower end of the fixed column through the bubble gathering plate of the defoaming device, the foam in the liquid medicine rises to the bubble rupture channel of the fixed column under the pushing of air source pressure, and the foam is impacted, extruded and broken after entering the bubble rupture channel under the combined action of the air source pressure and the bubble rupture channel, and finally discharged along the bubble rupture channel, so that the defoaming purpose is achieved. The utility model improves the quality, precision and efficiency of atomization inhalation, and saves energy consumption; the operation and the use are simple and easy.

Detailed Description

According to the figures 2-4, the utility model comprises an atomizing cup 1, an atomizing core 2, a cover body 3 and a defoaming device 4, wherein the bottom of the atomizing cup 1 is provided with an air source pipe interface 5, and the air source pipe interface 5 is connected with high-speed oxygen airflow through an air source pipe 7. One side of the upper part of the atomizing cup 1 is provided with an atomizing outlet 6, and the atomizing outlet 6 is connected with an oxygen mask. The defoaming device 4 comprises a fixed column 8 and a bubble aggregation plate 9, wherein a fixed passage 10 which penetrates through the fixed column 8 from top to bottom is arranged at the center of the fixed column 8, the atomizing core 2 penetrates through the fixed passage 10, the fixed passage 10 is fixed on the atomizing core 2, a plurality of bubble fracture passages 11 which penetrate through the fixed column 8 from top to bottom are arranged between the fixed passage 10 and the outer side surface of the fixed column 8, the bubble aggregation plate 9 is in a conical barrel shape with the upper opening diameter smaller than the lower opening diameter, the upper end of the bubble aggregation plate 9 is connected with the lower end of the fixed column 8, and a gap 12 is arranged between the lower end of the bubble aggregation plate 9 and the inner wall of the atomizing cup 1. The clearance distance 12 is 0.01-0.05 mm. The inner diameter of the bubble-fracturing channel 11 is 0.6-12 μm, preferably 10 μm. The height of the fixing column 8 is 60-100 mm, and preferably 80 mm. The number of the bubble-fracturing channels 11 is 36-60, preferably 60, and the bubble-fracturing channels are uniformly distributed in the side wall of the fixed column.

When the medicine liquid defoaming device is used, the gas source pipe 7 is connected with atomized medicine liquid, the medicine liquid is atomized under the thrust of the pressure of the gas source and then ascends to the atomizing outlet 6 through the gap 12 and the bubble fracture channel 11, when the medicine liquid generates foam, the foam is impacted, extruded and enters the bubble fracture channel 11 to be fractured under the combined action of the pressure of the gas source and the bubble fracture channel 11, and finally the foam is discharged along the bubble fracture channel 11, so that the defoaming is realized.
