Description

Children precision atomization device

Technical Field

The invention relates to the field of medical instruments, in particular to a child precision atomization device for implementing atomization treatment.

Background

Currently, inhalation therapy has been widely used in clinic, and after the 50 th 20 th century, along with the intensive research on the pathogenesis of asthma, the uk began to apply inhalation therapy to prevent and treat asthma, and finally selects a beta 2receptor agonist (beta 2receptor agonist, beta 2RA) to treat acute attack of asthma and uses ICS to prevent and treat relapse of asthma.

With the wide application in clinical treatment, the inhalation therapy is proved to have the advantages of quick effect, high curative effect, small adverse reaction, no wound, no pain, convenient use and the like. In 2003, the 'routine for preventing and treating children bronchial asthma' and 'guideline for diagnosing and preventing children bronchial asthma' in China also take inhalation therapy as the first choice therapy for preventing and treating asthma.

In foreign countries, clinical studies have successively demonstrated that glucocorticoid aerosol inhalation therapy has good efficacy, safety and compliance, and thus has been widely used in the field of respiratory related diseases (particularly allergic diseases) in pediatrics. The glucocorticoid aerosol inhalation therapy can effectively reduce the dosage of the glucocorticoid of the whole body, reduce the hospitalization rate and reduce the period of absence of lessons of children patients. In recent years, special atomization treatment centers are established in many hospitals in China, and glucocorticoid atomization inhalation therapy also becomes one of conventional treatment means for respiratory diseases.

However, the existing atomization therapy apparatus is not only complex in structure, but also difficult to control and adjust the discharge of atomized air for pediatrics with the existing hand-held or ordinary atomizer, and difficult to ensure the precision of the atomizer and to realize the household atomization.

Fig. 1 shows a child precision atomizing device disclosed in the present embodiment. The device comprises an air injection base, a medicament container 500, a jet flow lower baffle part 510 and a jet flow upper baffle part 520.

The air injection base in the embodiment is used for outputting air injection with different pressures to the air injection base; the medicament container 500, the lower jet baffle 510 and the upper jet baffle 520 form a liquid containing and atomizing assembly based on the venturi jet principle.

Specifically, fig. 2 and 3 show a sectional structure of the air injection base in the present embodiment.

The air injection base in the embodiment comprises a pressure regulating mechanism, an air injection cavity tube 700 and a vertebral rod.

The pressure regulating mechanism includes a first regulating seat 100, a second regulating seat 200, a telescopic seat 300 and a connecting seat 400.

In fig. 2, two ends of the second adjusting base 200 are respectively screwed with the first adjusting base 100 and the telescopic base 300. The two ends of the connecting base 400 are respectively connected with the telescopic base 300 and the air injection cavity tube 700 by screw threads.

The second adjustment base 200 is formed with an adjustment chamber extending therethrough in a longitudinal direction. The regulating cavity is T-shaped and is composed of a first regulating cavity 210 and a second regulating cavity 220 which are communicated from left to right in the figure. Wherein the first regulating chamber 210 has a smaller cross-sectional diameter than the second regulating chamber 220. A movable sleeve block is arranged in the second adjusting cavity 220 along the length direction, and the section diameter of the movable sleeve block is larger than that of the second adjusting cavity 220.

In this embodiment, the movable sleeve block is formed with a through T-shaped slot at the end opposite the first adjustment seat 100. The push rod 800 passes through the T-shaped sliding groove, the telescopic base 300 and the connecting base 400 and then extends into the jet cavity tube 700, and a sliding peripheral block matched with the T-shaped sliding groove is formed on the peripheral side of the push rod 800.

The first adjusting cavity 210 penetrates through an end of the second connecting seat 400, and the first sleeve connecting seat is connected with the push rod 800 through the first adjusting cavity 210 and the second adjusting cavity 220 by a first spring 810. The movable sleeve block is connected with the second adjusting seat 200 through the first adjusting cavity 210 and the second adjusting cavity 220, and a second spring 820 is connected with the second adjusting seat 200.

Through the above technical solution, in this embodiment, the second adjusting seat 200 and the telescopic seat 300 are relatively rotated, so that the first adjusting seat 100 and the second adjusting seat 200 are relatively close to or far away from each other.

Then during the approach of the second adjusting seat 200 and the telescopic seat 300; firstly, the second spring 820 tensions the movable sleeve block to make the movable sleeve block abut against the inner wall of the left side of the second adjusting cavity 220, the first spring 810 is compressed to generate a tendency of pushing the push rod 800 towards the telescopic base 300, so that the push rod 800 abuts tightly against the movable sleeve block; at the later time, due to the relative approach of the second adjusting seat 200 and the telescopic seat 300, the movable sleeve block is actually displaced toward the telescopic seat 300, the push rod 800 is actually displaced toward the telescopic seat 300, and the first spring 810 is continuously compressed. On the contrary, in the process that the second adjusting seat 200 and the telescopic seat 300 are far away, firstly, the first spring 810 tensions the movable sleeve block, so that the movable sleeve block abuts against the inner wall of the left side of the second adjusting cavity 220, and the first spring 810 is compressed; at the back, due to the relative distance between the retractable seat 300 and the second adjusting seat 200, the movable sleeve block is actually displaced by the reverse retractable seat 300, and the push rod 800 is actually displaced by the reverse retractable seat 300.

Further, in the present embodiment, the first adjusting seat 100 and the second adjusting seat 200 are relatively rotated to further move the push rod 800 closer to or away from the retractable seat 300.

In the process of approaching the first adjusting seat 100 and the second adjusting seat 200, no matter what state the second adjusting seat 200 and the telescopic seat 300 are, the first adjusting seat 100 approaches relative to the second adjusting seat 200, at this time, the first spring 810 compresses until the pulling force of the second spring 820, the movable sleeve block no longer abuts against the inner wall of the second adjusting cavity 220, and at this time, the push rod 800 is pushed towards the telescopic seat 300 together with the movable sleeve block under the acting force of the first spring 810. On the contrary, when the first adjusting seat 100 and the second adjusting seat 200 are far away from each other, the push rod 800 is pulled back by the reverse telescoping seat 300 together with the movable sleeve under the action of the second spring 820.

Moreover, since the push rod 800 and the movable sleeve block are slidably engaged, when the first adjusting seat 100 is too far away from the second adjusting seat 200, the movable sleeve block is separated from the push rod 800 by being limited by the inner wall of the second adjusting cavity 220. After the push rod 800 and the movable sleeve block are separated, the push rod 800 does not approach or leave the telescopic base 300 only when the second adjusting block and the telescopic base 300 are relatively rotated.

In this embodiment, since the jet chamber tube 700 is connected to the connecting seat 400, and the retractable seat 300 and the connecting seat 400 are both provided with through holes communicated with the jet chamber tube 700, when the push rod 800 is close to or far from the retractable seat 300, it is actually controlled whether the push rod 800 intervenes in the output airflow of the jet chamber tube 700, so as to control the pressure of the airflow.

Specifically, in this embodiment, one end of the air jet cavity tube 700 is communicated with the external air source through the vent groove 410 of the second adjusting seat 200.

The other end of the jet chamber tube 700 opposite to the connection seat 400 is configured as an open end in this embodiment, and the open end is configured with a tapered cavity penetrating and tapering inside.

Specifically, the vertebral rod coaxially extends into the air injection cavity tube 700 after passing through the telescopic seat 300 and the connecting seat 400, the end part of the vertebral rod extending into the air injection cavity tube 700 is constructed into a vertebral end part, and an air injection channel can be formed between the conical cavity and the vertebral end part in a matching manner when the conical cavity and the vertebral end part are close to each other. Then when the first adjusting seat 100 rotates relative to the second adjusting seat 200 and/or the second adjusting seat 200 rotates relative to the telescopic seat 300, the end of the vertebra can be partially pushed toward or away from the conical cavity, and the channel size of the air injection channel is expanded or reduced. Then the pressure of the jet base output air stream is inversely related to the channel size of the jet channel when the external air source is stable. The regulation of the output airflow can be achieved by the control of the pressure regulating mount by one skilled in the art.

Preferably, the retractable base 300 and the connecting base 400 may be configured as an integral structure in this embodiment. However, in the present embodiment, a telescopic base 300 connected between the connecting base 400 and the second adjusting base 200 is provided in consideration of the size setting of the actual product, etc. When the length of the telescopic base 300 is changed, the volume of the whole product can be changed, and the crowd adaptability is improved.

The connecting socket 400 is provided with an air source chamber at a side opposite to the sealing chamber 320, and the air source chamber is connected to an external air source through a vent groove 410 formed in a side wall of the connecting socket 400, and is communicated with the air injection chamber tube 700 in the connecting socket 400. Then the external gas source may be accessed through vent channel 410 in this embodiment.
