Ultrasonic dosing device

Abstract

The invention relates to the technical field of medical apparatus and instruments, and in particular relates to an ultrasonic dosing device. The device comprises a main probe; the main probe comprisesan electrode plate, an adhesive, an ultrasonic transducer, a patch carrier and a medicine containing patch; the electrode plate is arranged in a shell of the main probe and is bonded with the ultrasonic transducer through the adhesive; at the periphery of the electrode slice, one surface of the patch carrier is fixed on the electrode plate and is in good contact with the surface of the electrodeplate; the medicine containing patch capable of being immersed with liquid medicines is attached to the other surface of the patch carrier; wires of the electrode slice and the ultrasonic transducer are led out through signal wires to be connected with treatment equipment; the surface of the medicine containing patch is provided with a microstructure assisting in adsorbing the surface of skin, sothat the adsorption force between the ultrasonic medicine feeding device and the skin can be enhanced; and the device further comprises an auxiliary probe which can be electrically connected with themain probe, so that the dosing area can be expanded.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ultrasonic drug delivery device. Background technique [0002] With the development of society and the improvement of science and technology, more and more people pay attention to medical and health issues. Among the treatment methods at this stage, drug therapy is the most common treatment method. Its therapeutic principle is to transfer the drug from the outside of the body to the human body through a certain transport method to produce the drug effect. [0003] Transdermal Drug Delivery (TDD) refers to the absorption of drugs through the skin into the blood circulation at a certain rate to achieve effective blood drug concentration and achieve the treatment or prevention of diseases. With the development of biotechnology, there are more and more biological agents based on macromolecules such as polypeptides, proteins, and oligonucleotides. The route of adminis...

Problems solved by technology

[0009] However, in the practice of treatment, due to the limitations of the structure, there are still many inconveniences in operation. For example, the patent with the publication number CN208641537U discloses a transdermal drug delivery device, which includes a housing, a first microneedle system, a second microneedle system, and a second microneedle system. Needle system and pulse power supply, although the transdermal drug delivery device can improve the speed of transdermal drug delivery and the effect of transdermal drug delivery, and improve the therapeutic effect of the drug; but the transdermal drug delivery device, when the device is applied, needs to be held for a long time , the latter requires auxiliary means such as medical tape to fix the device on the treatment site, and since the transdermal drug delivery device needs to be used many times, after using medical tape, etc., it is troublesome to clean and may cause discomfort to the treatment site ; In addition, because the transdermal drug delivery device is in order to meet the treatment of different parts of the body, the area of ​​the device in contact with the skin is generally set relatively small, and when it needs to perform drug treatment on a larger area, multiple operations are required. this would waste a lot of time
