Problems solved by technology

[0011] At present, there is still a lack of devices that integrate the two functions of drug delivery and effective conduction of ultrasonic energy bodies
In addition, the device must effectively transmit the ultrasonic waves transmitted in one (directional) direction evenly to the body fluid in the patient's surgically formed hole, all surfaces of the inner wall of the hole, and all tissues adjacent to the surface of the inner wall without localized damage. The treatment efficiency is low due to the low ultrasonic energy received by the tissue, and there will be no irreversible damage to the tissue due to the excessively high ultrasonic energy received by the local tissue

Abstract

The invention discloses an implantable ultrasonic conduction and drug delivery device. The implantable ultrasonic conduction and drug delivery device comprises a drug accommodating component and a shell-like ultrasonic scattering component; the shell-like ultrasonic scattering component is fixed to the bottom of the drug accommodating component; the drug accommodating component is provided with aplurality of connecting through holes formed in the bottom; the multiple connecting through holes communicate with the bottom of the drug accommodating component and the shell-like ultrasonic scattering component; the shell-like ultrasonic scattering component is provided with a plurality of scattering through holes; the shell-like ultrasonic scattering component is arranged in a body cavity of apatient in a matched mode; a drug is injected into an accommodating space of the drug accommodating component and conveyed to the body cavity through the multiple scattering through holes of the shell-like ultrasonic scattering component; and directional ultrasonic waves are transmitted to the multiple scattering through holes of the shell-like ultrasonic scattering component, and evenly scatteredto tissue fluid in the body cavity, all the surfaces of the inner wall of the cavity and tissue of all the inner wall surfaces adjacent to the cavity through the multiple scattering through holes. According to the implantable ultrasonic conduction and drug delivery device, the drug administration efficiency can be improved.

Description

technical field [0001] The present invention relates to an ultrasonic conduction and drug delivery device, and in particular, to an ultrasonic conduction and drug delivery device implanted in a body cavity of a patient. Background technique [0002] Regarding the relevant technical background of the present invention, please refer to the technical documents listed below: [0003] [1] Sergio Dromi, Clin Cancer Res 2007, 13(9), p.2722; [0004] [2] Nikolitsa Nomikou, Acta Biomaterialia 8, 2012, pp.1273–1280; [0005] [3] Feng-Yi Yang, Journal of Controlled Release 150, 2011, pp.111–116. [0006] Many studies have confirmed that ultrasound can enhance the efficacy of drugs. Studies have confirmed that ultrasound can trigger drug carriers to release drugs. For example, the use of ultrasonic waves to interact with temperature-sensitive liposomes (a drug carrier) produces the effect of drug release for the treatment of cancer [1]. [0007] Studies have confirmed that the use ...
