In the process of using the product, the separating ring 13 separates the bladder into two cavities which are not communicated with each other, two liquid blocking rings 14 adjacent to the pathological change position are determined according to the specific pathological condition and the pathological change position of a patient, a liquid blocking injection tube 109 communicated with the liquid blocking ring 14 positioned at the rear part is selected, and air is injected into the liquid blocking ring 14 through the liquid blocking injection tube 109, so that the liquid blocking ring 14 positioned at the rear part is tightly propped against the inner wall of the bladder. Then, the medicine is injected into the medicine feeding cavity through the medicine feeding hole 104, and then the patient is adjusted to the position where the medicine is contacted with the inner wall of the bladder with the pathological change under the action of gravity. Then, a liquid blocking injection tube 109 communicated with the liquid blocking ring 14 positioned in front is selected, air is injected into the liquid blocking ring 14 through the liquid blocking injection tube 109, so that the liquid blocking ring 14 positioned in front is tightly abutted against the inner wall of the bladder, and a sealed administration cavity is formed by the two liquid blocking rings 14 and the inner wall of the bladder.
Similarly, when the lesion position is close to the separating ring 13, one liquid blocking ring 14 is selected to form a sealed medicine cavity together with the separating ring 13 and the inner wall of the bladder, and when the lesion position is close to the medicine feeding hole 104, one liquid blocking ring 14 is selected to form a sealed medicine cavity together with the inner wall of the bladder. The medicine action position is more concentrated, increases the effect of medicine, and the contact of medicine to the bladder inner wall that does not have pathological change is littleer simultaneously, prevents that the medicine from causing the damage to other bladder inner walls that do not have pathological change, reduces the medicine side effect, is favorable to the later stage rehabilitation after the patient treats.
