Description

Technical Field

[0001] The utility model relates to the field of drying devices, in particular to a drying device for preparing ultrasonic contrast agents. Background Art

[0002] An ultrasonic contrast agent is a liquid containing bubbles with a diameter of several micrometers. Utilizing the characteristic that a liquid containing bubbles has strong scattering of ultrasonic waves, clinically, the ultrasonic contrast agent is injected into the human blood vessels to enhance the ultrasonic Doppler signal of blood flow and improve the clarity and resolution of ultrasonic images. In the preparation process of the contrast agent, the drying process is an important step, mainly used to remove moisture and other components that may affect the stability and safety of the contrast agent. Specifically, the drying methods include vacuum freeze-drying, spray drying, etc.

[0003] Currently, the Chinese utility model with the publication number CN219120896U discloses a vacuum freeze-drying device for promoting the rapid sublimation of moisture, which relates to the field of vacuum freeze-drying technology and includes a vacuum freeze-drying machine main body, a storage rack, and a vacuum cover. The storage rack includes multiple trays, and there is a stir-frying mechanism and a material tray between two adjacent trays. A plurality of driving mechanisms are provided on one side of the vacuum cover. The stir-frying mechanism includes a fixed rod, the fixed rod is fixedly arranged at the bottom end of the tray, a sleeve is sleeved on the outer end of the fixed rod, a toothed scraper is fixedly arranged at the bottom end of the sleeve, and the toothed scraper is arranged on the top of the material tray and extends into the material tray. The material is dried by the vacuum freeze-drying machine main body, and the stir-frying mechanism can be driven by the driving mechanism, so that the toothed scraper in the stir-frying mechanism rotates in the material tray to facilitate stir-frying the material to accelerate the drying speed, promote the rapid sublimation of moisture in the material, greatly shorten the drying time, and thus improve the working efficiency.

[0004] Although the existing drying device can promote the sublimation of moisture by continuously changing the position of the material container, there are still other problems in the use process. For example, the distance between the trays cannot be adjusted. The trays and the rack are fixedly welded. Although it is stable and reliable, when the volume of the container placed is large and the distance is not enough, it may not be able to be placed. On the contrary, when the volume of the container placed is small but the required quantity is large, there is also a situation of space waste, and the flexibility is poor. Moreover, it does not have an automatic lifting function. When the device is in use, the sealing cover plays a role in isolating gas. The sealing cover needs to be repeatedly taken and placed by personnel during feeding. Since the sealing cover is relatively heavy, it is extremely laborious for personnel to take and place it, and the practicability is low. To solve the above problems, we propose a drying device for preparing ultrasonic contrast agents. Content of the Utility Model
