Ultrasonic atomization inhalation device special for general surgery department nursing

Abstract

The invention discloses an ultrasonic atomization inhalation device special for general surgery department nursing, and belongs to the technical field of medical instruments. The ultrasonic atomization inhalation device comprises a machine body; a liquid storage cavity is formed in the machine body; a top cover is detachably connected to the top of the machine body; an ultrasonic generator is installed at the bottom end in the liquid storage cavity; a bearing is installed in the middle of the interior of the top cover; the top cover is connected with a rotating rod in a matched mode through the bearing, and the bottom of the rotating rod extends into the liquid storage cavity; the rotating rod rotates to drive a connecting rod and bristles to rotate synchronously, and the bristles make contact with the inner wall of the liquid storage cavity in the rotating process to sweep the liquid storage cavity, so that the cleaning efficiency and the cleaning quality are greatly improved; pressing rods are extruded, and corresponding pistons B are pressed, therefore, vent holes B and vent holes A are staggered from each other, and the pistons B block the corresponding vent holes A, so that atomized gas remains in the liquid storage cavity, loss and waste are avoided, and liquid medicine is saved; and when the liquid medicine needs to be sucked continuously, only the pressing rods need tobe loosened, adjustment is flexible, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a special ultrasonic atomization inhalation device for general surgery nursing. Background technique [0002] Ultrasonic atomization is to use ultrasonic directional pressure to make the surface of the liquid bulge, and cavitation occurs around the raised liquid surface, so that the liquid is atomized into an aerosol of small molecules, so that the drug molecules can directly enter the capillaries or alveoli through the aerosol to achieve therapeutic effect. It is suitable for colds, allergic rhinitis, nasal congestion, nasal polyps, emphysema, acute and chronic pharyngitis, laryngitis, bronchitis, bronchial asthma and other upper respiratory tract infectious diseases, and is also suitable for the treatment of old and young patients and people with limited mobility. Often used in general surgical care. [0003] Patent No. CN 109078243 A discloses a special ultrasonic ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned ultrasonic atomization device has the following disadvantages during use 1. When the atomization device is used, water and liquid medicine need to be filled in the liquid storage chamber for atomization treatment. After use, the interior of the liquid storage chamber needs to be cleaned. The opening of the liquid cavity is small, which makes it difficult to clean the inner wall, and the residual liquid medicine will affect the quality of the subsequent use of the atomization device; 2. When the atomization device is in use, the atomized gas is usually directly discharged into the breathing mask through the pipeline , during use, it is necessary to remove the breathing mask at intervals to avoid long-term inhalation of the liquid medicine and cause discomfort to the user. During the suspension process, the liquid medicine continues to be atomized and discharged, which will cause waste in the pharmaceutical industry and increase the cost of use. Therefore, we propose a special ultrasonic atomization inhalation device for general surgery nursing
