when the external force is applied on both the first action area (212) and the second action area (214) simultaneously, the communication between the urine storage cavity (215) and the urine outlet (32) is blocked;
according to the deformation of the first pressure transmission surface (211) and/or the second pressure transmission surface (213), the external force applied on the first action area (212) and/or the second action area (214) can be removed, and when any one external force applied on the first action area (212) and the second action area (214) is removed, the blockage between the urine storage cavity (215) and the urine outlet (32) can be removed, the communication between the urine storage cavity (215) and the urine outlet (32) can be restored.

Abstract
A urine drainage and control device and system, and voiding method includes a urine inlet, a urine outlet and a bionic bladder unit. The bionic bladder unit includes a urine storage cavity connected to the urine inlet and outlet via a tube, and a first and second pressure sensing surface deforming with urine pressure in the urine storage cavity. A lower connecting tube has a first and second action area. In one aspect when force is applied on the action areas simultaneously, communication between the urine storage cavity and the urine outlet is ended. Other applications of force allows communication with the urine outlet. The urine drainage device senses the change of the urine pressure via the deformation of the pressure sensing surfaces, determines whether to conduct voiding according to the deformation level of the pressure sensing surfaces thus assisting a patient to void.

21. A micturition method which protects the bladder function, method comprises the steps of:
-
presetting a threshold of releasing pressure as well as a time to start releasing pressure and a duration of releasing pressure; collecting the pressure in the bladder; judging whether the pressure is equal to or greater than the preset threshold of releasing pressure; and if the judgement result is that the pressure is equal to or greater than the preset threshold of releasing pressure, then starts micturition to release pressure within the time to start releasing pressure, and the time for releasing pressure is the preset duration of releasing pressure. - View Dependent Claims (22, 23, 24)
