Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a clinical atomizing spray device for respiratory medicine. Background Art

[0002] In modern medicine, the treatment of respiratory diseases is gaining increasing attention, especially with the continuous advancement of treatments for acute and chronic respiratory diseases. As a crucial tool in the treatment of respiratory diseases, medical atomizers, with their ability to convert liquid medicine into tiny particles and deliver them directly to the lesions through breathing, have become an indispensable part of clinical treatment. These devices are used for the non-invasive treatment of a variety of tracheal, bronchial, alveolar, and intrathoracic diseases, including colds, fevers, coughs, asthma, sore throats, pharyngitis, rhinitis, bronchitis, and pneumoconiosis, greatly improving the comfort and efficiency of treatment.

[0003] However, existing medical atomization spray equipment often uses simple stirring methods during the liquid medicine preparation stage, such as magnetic stirrers or mechanical stirring rods, which results in poor mixing between drugs. Uneven drug mixing will directly affect the therapeutic effect after atomization. Excessive concentration of some drugs may cause local irritation or adverse reactions, while too low a concentration may not achieve the desired therapeutic effect. In addition, to further improve the mixing effect between drugs, some medical atomizers are also equipped with a heating function, which improves the mixing degree between drugs by moderately heating the liquid medicine. However, existing heating systems often use fixed heating temperatures and modes. This fixed heating method may lead to excessive and / or repeated heating of drugs, especially for heat-sensitive drugs. Excessive and / or repeated heating may destroy the chemical structure of the drug, causing drug deterioration, reducing efficacy, and even producing toxic substances. Summary of the Invention

The piston rod of the suction assembly 14 is connected to a connecting block arranged in cooperation with the annular groove, and the connecting block is slidably arranged on the inner side of the annular groove. The inlet and outlet of the suction assembly 14 are connected by a three-way pipe 15. The two communicating ends on the lower side of the three-way pipe 15 are respectively connected to the mixing box 2 and the medicine storage box 3, and the three-way pipes 15 connected by the two suction assemblies 14 are in the same horizontal straight line. The communicating ends of the two three-way pipes 15 and the mixing box 2 are both arranged in the middle of the stirring paddle. Both ends of the lower side of the three-way pipe 15 are provided with a one-way valve 16. Among them, the one-way valve 16 between the medicine storage box 3 and the three-way pipe 15 controls the one-way flow of the medicine liquid from the medicine storage box 3 to the suction assembly 14 side, and the one-way valve 16 between the three-way pipe 15 and the mixing box 2 controls the one-way flow of the medicine liquid from the suction assembly 14 to the mixing box 2 side.

[0033] The base box 1 is also connected to a pump 17, the inlet and outlet ends of the pump 17 are respectively connected to a liquid guide tube 18 and a three-way valve 19, the lower end of the liquid guide tube 18 is connected to the medicine mixing box 2, and the other two connecting ends of the three-way valve 19 are connected to the atomizing assembly through a shunt pipe 24. The atomizing assembly is provided with a heating assembly, which includes a heating box 20 and four resistive heating plates 23 for heating the heating box 20. The heating box 20 is cylindrical, and the four resistive heating plates 23 are evenly distributed around the outside of the heating box 20. The end of the shunt pipe 24 away from the three-way valve 19 is connected to the heating box 20. The heating box 20 It is connected to the base box 1 through a spring 22, the resistive heating plate 23 is fixedly connected to the base box 1, and the heating box body 20 is fixedly connected to a sliding block 21, which slides through the resistive heating plate 23.

In this embodiment, the diverter pipe 24 and the atomizing pipe 25 are both hoses, and the end of the atomizing pipe 25 away from the heating box body 20 is detachably connected to an atomizing nozzle 26.

[0034] The specific implementation process is as follows:

[0035] When using this atomizing spray device, first hold the transfer handle 6, and transfer the entire device to the designated position under the action of the transfer wheel group 5, and then add two different liquid medicines into the medicine storage box 3 through the medicine inlet 4 respectively, and then start the dual-output shaft motor 8 to draw the liquid medicine in the medicine storage box 3 into the medicine mixing box 2 for mixing. After the liquid medicine is mixed to the specified state, start the pump 17 again, and let the mixed liquid medicine in the medicine mixing box 2 enter the heating box 20 through the liquid guide tube 18 and the diversion tube 24 for heating, and finally spray it out through the atomizing tube 25 and the atomizing nozzle 26 to complete the atomizing spraying demand for the liquid medicine.

[0036] Among them, a one-way valve 16 is set at the two ports of the three-way pipe 15 connecting the medicine storage box 3 and the medicine mixing box 2. When the dual-output shaft motor 8 drives the piston rod to move upward, the suction component 14 draws the medicine liquid from the medicine storage box 3 into its cylinder. When the piston rod moves downward, the medicine liquid in the cylinder is discharged into the medicine mixing box 2. In the process of drawing and discharging the medicine liquid, the suction component 14 makes the medicine liquid itself dispersed under the interaction of the liquids, and when discharging the medicine liquid into the medicine mixing box 2, the liquids and the stirring element 10 impact each other, so that the medicine liquid is dispersed; and in the process of the suction component 14 drawing the medicine liquid from the medicine storage box 3 to the medicine mixing box 2, the stirring element 10 is always in a rotating state, constantly stirring the different medicine liquids in the medicine mixing box 2 to mix them, thereby increasing the mixing effect between the medicine liquids.

[0037] The heating box 20 of the heating assembly is connected to the base box 1 through a spring 22. The more liquid medicine there is in the heating box 20, the greater the pressure on the spring 22 and the greater its deformation. Conversely, as the liquid medicine in the heating box 20 decreases, the pressure on the spring 22 will also decrease and its deformation will also decrease. The heating box 20 is connected to a sliding block 21 that is slidably connected to the resistive heating plate 23. When the liquid medicine in the heating box 20 changes, the sliding block 21 will slide relative to the resistive heating plate 23 under the action of the spring 22. The sliding block 21 slides through the resistive heating plate 23, and the sliding block 21 and the resistive heating plate 23 are respectively connected to the power supply through electrical wires. The heating power of the resistive heating plate 23 is linearly related to the sliding position of the sliding block 21 relative to it, so that the heating power of the resistive heating plate 23 is linearly related to the liquid medicine in the heating box 20. That is, the more liquid medicine there is in the heating box 20, the greater the heating power of the resistive heating plate 23, so as to ensure the heating effect and efficiency of the liquid medicine. Conversely, the less liquid medicine there is in the heating box 20, the smaller the heating power of the resistive heating plate 23, so as to avoid excessive and / or repeated heating of the liquid medicine, which may cause changes in the chemical structure of the medicine and ensure the efficacy of the medicine.
