The invention relates to the technical field of medical instruments, and provides an antibacterial device for a catheter and an antibacterial catheter. The device comprises an upper shell, a lower shell, a controller, a vibrating element, a first anti-vibration pad and a pressure sensor, the upper shell movably covers the opening of the lower shell, first notches are oppositely formed in the edgesof the front side and the rear side of the upper shell, and second notches corresponding to the first notches are formed in the edges of the front side and the rear side of the lower shell; a vibration element is connected with the inner wall of the lower shell sequentially through the first anti-vibration pad and the pressure sensor; the controller is electrically connected with the pressure sensor and the vibration element and used for adjusting the amplitude of the vibration element according to the pressure value detected by the pressure sensor. The antibacterial catheter comprises the catheter and an antibacterial device for the catheter body. According to the invention, the same antibacterial effect can be generated for different catheters, and the first anti-vibration pad can be used for preventing vibration energy from being transmitted to the lower shell, so that the vibration attenuation is remarkably reduced.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an antibacterial device for a catheter and an antibacterial catheter. Background technique [0002] With the advancement of medical technology, more and more treatments require the use of indwelling medical devices in the body. For example, medical catheters such as tracheal catheters, arteriovenous catheters, gastric tubes, peritoneal dialysis catheters, and urinary catheters. Although these medical catheters solve many clinical problems, they are easy to breed bacteria because they need to stay in the human body for a long time. These bacteria exist in a free state at the initial stage, and when they attach to the surface of a specific object, they will gradually adhere to each other and form a biofilm with a complex structure. After the biofilm is formed, it is usually necessary to increase the dose of antibiotics by hundreds or thousands of times to achieve the same...
