Description

A nebulizer that can meet any use angle

technical field

The invention relates to a medical nebulizer, in particular to a medical nebulizer which can be placed horizontally.

Background technique

Compared with the traditional method of taking medicine to treat asthma and other respiratory diseases, the medical nebulizer atomizes the medicine liquid into tiny particles, and the medicine enters the respiratory tract and lungs for deposition through inhalation, so as to achieve painless, rapid and effective treatment. The current nebulizers are generally divided into three types: ultrasonic nebulizer, mesh nebulizer and gas compression nebulizer.

As shown in Figure 13, the gas compression nebulizer uses compressed air to pass through a small nozzle at a high flow rate, thereby forming a Venturi effect, and the negative pressure generated drives the liquid medicine to be sprayed onto the obstacle together. When the impact splashes around, the liquid droplets become mist particles and are ejected from the air outlet pipe. There are mainly two problems in the process of using this atomizer:

First, it can only be placed vertically or slightly tilted at a certain angle during use. This is because when the inclination angle of the atomizer is too large, on the one hand, the liquid medicine is easy to leak, and on the other hand, the liquid level of the liquid medicine cannot submerge the lower port of the diversion sleeve. Since the density of the air is much smaller than that of the liquid medicine, the atmospheric pressure will cause a large amount of air to be ejected from the annular gap between the diversion sleeve and the central spinal canal, while the ejection amount of the liquid medicine will be extremely small or even non-existent. It is difficult to form an effective atomization when the liquid medicine is sprayed out. Such requirements for use are generally satisfactory for adults, but for some infants, especially some infants, it is very inconvenient, and the effective cooperation of the child is often not obtained, and the therapeutic effect will get twice the result with half the effort.

The second, there is the situation of liquid medicine waste. Because even if the atomizer is used strictly in a vertical manner, when the liquid level of the liquid medicine is separated from the lower end surface of the flow guide sleeve, the liquid medicine cannot be sprayed, that is to say, it will always be wasted part of the liquid medicine.

As shown in FIG. 6 , the bottom surface 12 is provided with a liquid medicine injection port 122 for injecting liquid medicine, and the liquid medicine injection port 122 is provided with a sealing cover (not shown in the figure).

The main housing 1 has an integrated structure and is made of transparent materials. As a specific implementation, the main housing 1 in this embodiment is made of transparent hard plastic.

As shown in Figure 3 and Figure 4, the upper cover 2 is fastened above the main housing 1, and the inside of the upper cover 2 is provided with a collision plate 21 corresponding to the annular gap, One side of the collision plate 21 is provided with an air outlet pipe interface 22 for connecting the air outlet pipe.

Further, in order to increase the collision area between the liquid medicine and the collision plate 21 and improve the atomization effect, the collision plate 21 is in the shape of an umbrella.

As shown in Fig. 5, Fig. 6 and Fig. 12, the capsule 5 is made of transparent soft plastic. The outside of the capsule 5 is pressed against the first stepped surface 13 by the first pressure ring 3 , and the inside of the capsule 5 is pressed against the second step by the second pressure ring 4 . Adhesives are respectively provided on the surface 17 and between the capsule 5 and the first stepped surface 13 , the second stepped surface 17 , the first pressure ring 3 and the second pressure ring 4 . The main purpose of this design has two, one is to ensure the smoothness of the connection between the capsule membrane 5 and the main housing 1, and on the other hand, because the first pressure ring 3 and the second pressure ring 4 are rigid, Can increase bonding strength.

As shown in Fig. 3 and Fig. 7, the exhaust assembly 6 includes a hemispherical piston 61 arranged inside the main casing 1, and the piston 61 is provided along the axial direction for accommodating the The through hole of the flow guide sleeve 16. The piston 61 is made of transparent material. As a specific implementation, the piston 61 in this embodiment is made of transparent hard plastic. On the plane of the upper end of the piston 61, several guide posts 62 are evenly distributed along the circumferential direction, and the guide posts 62 extend upwards and protrude from the upper surface of the upper cover 2, and the upper ends of the guide posts 62 pass through The ring-shaped pressing plates 63 are connected to each other.
