Problems solved by technology

[0004] For the above-mentioned compressed air nebulizer, it is most widely used clinically in infants and young children; in actual use, because infants and young children are usually very uncooperative, the nebulizer often shakes or even topples during use. The liquid medicine in the medicine liquid chamber will not be stably sucked into the injection channel 20, and may even flow out of the medicine liquid chamber 10 due to overturning; therefore, the current nebulizer is very troublesome to use

Embodiment 1

[0016] exist figure 2 , image 3 In the first shown embodiment, the medical nebulizer includes a liquid medicine chamber 10, the lower end of the liquid medicine chamber 10 is provided with an air inlet 101, and a section of spray pipe 200 extends upward from the air inlet 101; A collision body 4 is arranged above the injection pipe 200; a mist outlet 100 is provided on the side of the liquid medicine chamber 10; the upper end of the liquid medicine chamber 10 is sealed by a funnel-shaped sealing plate 11, and the center of the sealing plate 11 communicates downward. A liquid medicine tube 300, the liquid medicine pipe 300 includes more than two spiral coils 3001 connected in series, each of the spiral coils 3001 is arranged in parallel in the liquid medicine cavity from top to bottom, and its plane spiral path such as image 3 As shown in the figure; the lower end of the liquid medicine pipe 300 is connected to the injection pipe 200 in a transverse direction.

Embodiment 2

[0020] Figure 4 Shown is the second embodiment of the medical nebulizer, which is different from the first embodiment in that: a whistle 6 is connected in series in the injection pipe 200, and a parabolic surface is covered above the collision body 4 Reflector 7 , the focal point of the parabolic reflector 7 is at the place where the lower end of the collision body 4 faces the injection pipe 200 .

[0021] The additional effect of embodiment two is: when the high-speed airflow passes through the whistle tube 6, a whistle with a higher frequency will be produced, and after the whistle passes through the direct light and the reflection of the parabolic reflector, most of the whistle will propagate towards the high-speed airflow, Due to the huge relative speed between the high-speed airflow and the whistle, the frequency of the whistle is converted to the ultrasonic band by the Doppler effect, and the gas-liquid mixture in the spray pipe 200 is ultrasonically atomized, thereby f...

Abstract

The invention provides a medical atomizer which comprises a liquid medicine cavity, wherein an air inlet is formed in the lower end of the liquid medicine cavity; one section of injection pipe is arranged by extending upwards from the air inlet; a collider is arranged above the injection pipe; a mist outlet is formed in the side face of the liquid medicine cavity; the upper end of the liquid medicine cavity is sealed by a funnel-shaped sealing plate; the center of the sealing plate is downwards communicated with a liquid medicine pipe; the liquid medicine pipe comprise more than two spiral coil pipes which are mutually connected in series; all the spiral coiled pipes are arranged in the liquid medicine cavity from top to bottom in a parallel manner; the lower end of the liquid medicine pipe is transversely communicated to the injection pipe. When the medical atomizer is used, even if the medical atomizer is positioned in a shake or turnover state, liquid medicine can be stably atomized, and actual operation is facilitated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a respiratory medical nebulizer. Background technique [0002] A nebulizer is a commonly used medical device, mainly used to treat respiratory diseases; its main function is to atomize liquid medicine into water mist, so that patients can directly inhale the medicine into the respiratory tract, thereby directly acting on the surface of the respiratory tract, therefore, atomization Drug therapy usually has a good therapeutic effect. [0003] There are two main types of nebulizers at present, one is a compressed air nebulizer, and the other is an ultrasonic nebulizer. For the compressed air atomizer, its structural principle is as follows: figure 1 As shown, the atomizer includes a liquid medicine chamber 10, and the liquid medicine is poured into the chamber from the top of the liquid medicine chamber 10 and kept at the bottom of the liquid medicine chamber; the bottom of the li...
