The invention discloses an atomization device with controllable flow, flow velocity and particle size, relates to the technical field of medical atomizers, and provides the following scheme that the atomization device comprises a box body, a controllable airflow conveying mechanism is arranged on the right side of an inner cavity of the box body, and a conveying port of the controllable airflow conveying mechanism is connected with an airflow conveying pipeline; a liquid medicine conveying mechanism is arranged in the middle area of the inner cavity of the box body, and the tail end of the liquid medicine conveying mechanism is inserted into the airflow conveying pipeline. According to the technical scheme, the airflow conveying pipeline and the controllable airflow conveying mechanism are matched with each other, the flow speed and flow of airflow for conveying atomized liquid medicine are controlled, the medicine feeding amount is selected according to the treatment purpose of a patient, and the problem that the patient feels uncomfortable due to large-amount medicine feeding can be solved. In addition, the size of atomized particles of the liquid medicine is adjusted by means of the liquid medicine conveying mechanism, so that the medicine can reach a target area more effectively, and the situation that the medicine is deposited on the pharynx and the bronchus and consequently the utilization rate of the medicine is reduced is prevented.

The present invention relates to the technical field of fire fighting equipment, and in particular to an emergency fire truck with a CAFS system, wherein a base is sleeved on the outer wall of a nozzle, the top and bottom surfaces of the base are arc-shaped structures, and are sliding areas, two half-tubes are respectively slidably arranged on the top and bottom surfaces of the base, the two half-tubes are mirror-distributed, and the two half-tubes are symmetrical along an axis, a push rod is arranged on the side wall of the base, a connecting block is arranged on the output end of the push rod, the first ends of the two connecting rods are respectively hinged on the connecting block, the second ends of the two connecting rods are respectively hinged on the outer walls of the two half-tubes, two first coil springs are respectively arranged at the connection between the two connecting rods and the connecting block, two second coil springs are respectively arranged at the connection between the two connecting rods and the two half-tubes, a locking mechanism is arranged on the outer walls of the two half-tubes, and a flip cover device is detachably installed on the ends of the two half-tubes, so as to improve the applicability of the system by changing the extension length of the nozzle.

The application relates to the technical field of supramolecular, in particular to a ternary eutectic solvent as well as a preparation method and application thereof. The ternary eutectic solvent is prepared from component A, component B and component C, wherein the component A is a hydrogen bond donor, the component B is a hydrogen bond acceptor, and the component C is adenosine. The intermolecular interaction mode of the ternary eutectic solvent breaks the original strong force between adenosine molecules, so that the adenosine can be uniformly dispersed in the ternary DES system in the form of single molecules or small aggregates, thereby significantly improving the solubility of adenosine. Meanwhile, the existence of the ternary DES changes the dissolution and release behavior of the drug in the body, promotes the absorption of the drug, and greatly improves the bioavailability of adenosine.
