The present invention is a transurethral bladder communication device, which is characterized in that the communication body includes a buffer chamber and a drug administration chamber, the top of the buffer chamber is connected to the animal catheter, and the bottom end is provided with a buffer chamber sealing rubber plug. A central hole is provided in the buffer chamber plugging rubber plug, the annular wall of the buffer chamber is connected to the bottom end of the connection port, the top end of the connection port is sealed to one end of the drug delivery tube, and the other end is sealed to the top end of the drug delivery chamber. The bottom end of the drug delivery cavity is provided with a drug delivery cavity seal, the inner core includes a metal inner core, a base and a handle, the base is connected and fixed to the handle, the base is provided with a through hole, and the bottom of the metal inner core The end is inserted and fixed in the through hole. The invention provides a minimally invasive communication device for infusing the bladder of experimental animals with medicinal liquid and subsequent laser irradiation treatment through the urethra, so as to achieve the purpose of safety, effectiveness and minimal invasiveness.
Description
technical field [0001] The invention relates to a transurethral bladder communication device, which is an experimental device for basic research on animal bladder. Background technique [0002] At present, for the research of bladder diseases, researchers often conduct experiments and studies by establishing animal models of corresponding diseases. During the experiment, drugs and cells and other biological agents need to be injected into the bladder of animals to observe the formation and development of inflammation and tumors in the bladder. For the treatment of related diseases with drugs, the research on biomaterials has accelerated the development of auxiliary experimental equipment. Most biomaterials, especially nanomaterials, can only exert their biological effects under laser irradiation. The principle is that they have photothermal properties. After the drug is activated by the laser, it produces a photodynamic reaction to produce highly active singlet oxygen. The s...
